    2015-01-01

    Fish perceive water motions and pressure gradients with their lateral line. Lateral line information is used for prey detection, spatial orientation, predator avoidance, schooling behavior, intraspecific communication and station holding. The lateral line of most fishes consists of superficial neuromasts (SNs) and canal neuromasts (CNs). The distribution of SNs and CNs shows a high degree of variation among fishes. Researchers have speculated for decades about the functional significance of this diversity, often without any conclusive answers. Klein et al. (2013) examined how tubules, pore number and pore patterns affect the filter properties of lateral line canals in a marine teleost, the black prickleback (Xiphister atropurpureus). A preliminary mathematical model was formulated and biomimetic sensors were built. For the present study the mathematical model was extended to understand the major underlying principle of how canal dimensions influence the filter properties of the lateral line. Both the extended mathematical model and the sensor experiments show that the number and distribution of pores determine the spatial filter properties of the lateral line. In an environment with little hydrodynamic noise, simple and complex lateral line canals have comparable response properties. However, if exposed to highly turbulent conditions, canals with numerous widely spaced pores increase the signal to noise ratio significantly. © 2014 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

  4. Lateral line canal morphology and signal to noise ratio

    The lateral line system of fish is important for many behaviors, including spatial orientation, prey detection, shoaling, intra specific communication and entraining. The smallest sensory unit of the lateral line is the neuromast that occurs free standing on the skin and in fluid filled canals. With aid of the lateral line fish perceive minute water motions. In their natural habitat fish are not only faced with biotic water motion but also with the abiotic fluctuations caused by various inanimate sources. The detection of meaningful signals is crucial for survival, and therefore animals should be able to separate meaningful signals from noise. Fishes live in various habitats (e.g. in still water or in running water). Therefore it is not surprising that the number and distribution of neuromasts as well as canal dimension, canal shape and canal branching patterns differ among fish species. We studied how lateral line canal parameters influence the filter properties of lateral line canals. To do so we exposed artificial lateral line canals, equipped with artificial neuromasts (sensors), to the vortex street shed by a submerged cylinder and to air bubble noise. We found that certain canal parameters significantly can enhance the signal to noise ratio.

    Full Text Available Fish sense water motions with their lateral line. The lateral line is a sensory system that contains up to several thousand mechanoreceptors, called neuromasts. Neuromasts occur freestanding on the skin and in subepidermal canals. We developed arrays of flow sensors based on lateral line canal neuromasts using a biomimetic approach. Each flow sensor was equipped with a PDMS (polydimethylsiloxane lamella integrated into a canal system by means of thick- and thin-film technology. Our artificial lateral line system can estimate bulk flow velocity from the spatio-temporal propagation of flow fluctuations. Based on the modular sensor design, we were able to detect flow rates in an industrial application of tap water flow metering. Our sensory system withstood water pressures of up to six bar. We used finite element modeling to study the fluid flow inside the canal system and how this flow depends on canal dimensions. In a second set of experiments, we separated the flow sensors from the main stream by means of a flexible membrane. Nevertheless, these biomimetic neuromasts were still able to sense flow fluctuations. Fluid separation is a prerequisite for flow measurements in medical and pharmaceutical applications.

    Mudflow in Siring Village, Sidoarjo Regency, Indonesia, has been in eruption since May 29, 2006. It still shows irregular large bursts which loaded in a sludge reservoir with capacity of 59 million m3. From 2007 until 2015, there were more than 20 studies which concluded that the mudflow could be used as a mixture of building materials. However, the studies were not detailed and needed further research. This research aims to investigate the use of mudflow as tertiary irrigation canal lining material. This research comes with several laboratory tests to obtain a mixture that is solid and water-resistant. The methods that were used are descriptive methods as follows: 1). Sampling of mudflow, to be analyzed in Material Testing Laboratory. 2). Sampling of soil at research site, to be analyzed in Soil Mechanics Laboratory 3). Mixing of materials which are consist of mudflow and other materials and doing strength test in the laboratory. 4). Installation of tertiary irrigation canal lining using materials that have been tested. 5). Observation of lining's strength inactive soil pressure-bearing and its impermeability. It is expected that the results of this research will be applied extensively throughout the tertiary irrigation canals, so mudflow can be utilized as raw materials that are environmentally friendly, which are able to help preserving the environment, also to reduce the removal of sand / rock in the river, which has been used for lining materials, that benefits in preventing damage to the river ecosystem.

  8. Heterochrony, modularity, and the functional evolution of the mechanosensory lateral line canal system of fishes.

    Bird, Nathan C; Webb, Jacqueline F

    2014-01-01

    The canals of the mechanosensory lateral line system are components of the dermatocranium, and demonstrate phenotypic variation in bony fishes. Widened lateral line canals evolved convergently in a limited number of families of teleost fishes and it had been hypothesized that they evolved from narrow canals via heterochrony and explore modularity in the lateral line system. Two species of cichlids with different canal phenotypes were used to test a hypothesis of heterochrony. Histological material prepared from ontogenetic series of Aulonocara stuartgranti (widened canals) and Tramitichromis sp. (narrow canals) was analyzed using ANCOVA to determine rates of increase in canal diameter and neuromast size (length, width) and to compare the timing of onset of critical stages in canal morphogenesis (enclosure, ossification). A faster rate of increase in canal diameter and neuromast width (but not length), and a delay in onset of canal morphogenesis were found in Aulonocara relative to Tramitichromis. However, rates of increase in canal diameter and neuromast size among canals, among canal portions and among canals segments reveal similar trends within both species. The evolution of widened lateral line canals is the result of dissociated heterochrony - acceleration in the rate of increase of both canal diameter and neuromast size, and delay in the onset of canal morphogenesis, in Aulonocara (widened canals) relative to Tramitichromis (narrow canals). Common rates of increase in canal diameter and neuromast size among canal portions in different dermatocranial bones and among canal segments reflect the absence of local heterochronies, and suggest modular integration among canals in each species. Thus, canal and neuromast morphology are more strongly influenced by their identities as features of the lateral line system than by the attributes of the dermatocranial bones in which the canals are found. Rate heterochrony manifested during the larval stage ensures that the

    2014-08-01

    The lateral line system of teleost fish is composed of mechanosensory receptors (neuromasts), comprising superficial receptors and others embedded in canals running under the skin. Canal diameter and size of the canal neuromasts are correlated with increasing body size, thus providing a very simple system to investigate mechanisms underlying the coordination between organ growth and body size. Here, we examine the development of the trunk lateral line canal system in zebrafish. We demonstrated that trunk canals originate from scales through a bone remodeling process, which we suggest is essential for the normal growth of canals and canal neuromasts. Moreover, we found that lateral line cells are required for the formation of canals, suggesting the existence of mutual interactions between the sensory system and surrounding connective tissues.

  11. The functional significance of lateral line canal morphology on the trunk of the marine teleost Xiphister atropurpureus (Stichaeidae).

    Klein, Adrian; Münz, Heinrich; Bleckmann, Horst

    2013-09-01

    We investigated the filter properties of the highly branched trunk lateral lines of the stichaeid Xiphister atropurpureus and compared them to the filter properties of simple lateral line canals. For this purpose artificial canals were constructed, some of which were fitted with artificial neuromasts. In still water, the response of a simple canal versus two types of Xiphister-like canals to a vibrating sphere stimulus were similar, as was the decrease in the responses as a function of sphere distance. Also comparable was the mechanical coupling between neighboring parts of the main canal. However, compared to the simple canal, the Xiphister-like canals showed a lower spatial resolution. Equipping artificial lateral line canals with artificial neuromasts revealed that Xiphister-like canals, i.e., lateral lines canals with tubuli that contained widely spaced pores, improve the signal-to-noise ratio in a highly turbulent environment. Even though a reduced spatial resolution is the price for this improvement, Xiphister may compensate for this compromise by having four instead of the usual single trunk lateral line canal. We suggest that lateral line canals with tubuli that contain widely spaced pores and multiple lateral line canals on each body side are an adaptation to a highly turbulent aquatic environment.

  12. Morphology and ontogeny of multiple lateral-line canals in the rock prickleback, Xiphister mucosus (Cottiformes: Zoarcoidei: Stichaeidae).

    2015-10-01

    The structure and ontogeny of lateral-line canals in the Rock Prickleback, Xiphister mucosus, were studied using cleared-and-stained specimens, and the distribution and morphology of neuromasts within lateral-line canals were examined using histology. X. mucosus has seven cephalic canals in a pattern that, aside from four branches of the infraorbital canals, is similar to that of most teleostean fishes. Unlike most other teleosts, however, X. mucosus features multiple trunk lateral-line canals. These include a short median posterior extension of the supratemporal canal and three paired, branching canals located on the dorsolateral, mediolateral, and ventrolateral surfaces. The ventrolateral canal (VLC) includes a loop across the ventral surface of the abdomen. All trunk canals, as well as the branches of the infraorbitals, are supported by small, dermal, ring-like ossifications that develop independently from scales. Trunk canals develop asynchronously with the mediodorsal and dorsolateral canals (DLC) developing earliest, followed by the VLC, and, finally, by the mediolateral canal (MLC). Only the mediodorsal and DLC connect to the cephalic sensory canals. Fractal analysis shows that the complexity of the trunk lateral-line canals stabilizes when all trunk canals develop and begin to branch. Histological sections show that neuromasts are present in all cephalic canals and in the DLC and MLC of the trunk. However, no neuromasts were identified in the VLC or its abdominal loop. The VLC cannot, therefore, directly function as a part of the mechanosensory system in X. mucosus. The evolution and functional role of multiple lateral-line canals are discussed. © 2015 Wiley Periodicals, Inc.

  13. Morphology of lateral line canals in Neotropical freshwater stingrays (Chondrichthyes: Potamotrygonidae from Negro River, Brazilian Amazon

    Directory of Open Access Journals (Sweden)

    Akemi Shibuya

    Full Text Available The relationship between the distribution of the lateral line canals and their functionality has not been well examined in elasmobranchs, especially among Neotropical freshwater stingrays of the family Potamotrygonidae. The spatial distribution of the canals and their tubules and the quantification of the neuromasts were analyzed in preserved specimens of Potamotrygon motoro, P. orbignyi, Potamotrygon sp. "cururu", and Paratrygon aiereba from the middle Negro River, Amazonas, Brazil. The hyomandibular, infraorbital, posterior lateral line, mandibular, nasal and supraorbital canals were characterized and their pores and neuromasts quantified. The ventral canals are known to facilitate the accurate localization of prey items under the body, and our results indicate that the dorsal canals may be employed in identifying the presence of predators or potential prey positioned above the stingray's body. The presence of non-pored canals in the ventral region may be compensated by the high concentration of neuromasts found in the same area, which possibly allow the accurate detection of mechanical stimuli. The concentration of non-pored canals near the mouth indicates their importance in locating and capturing prey buried in the bottom substrate, possibly aided by the presence of vesicles of Savi.

    Surface mounted 'smart skin' can enhance the situational and environmental awareness of marine vehicles, which requires flexible, reliable, and light-weight hydrodynamic pressure sensors. Inspired by the lateral line canal system in fish, we developed an artificial lateral line (ALL) canal system by integrating cantilevered flow-sensing elements in a polydimethylsiloxane (PDMS) canal. Polypropylene and polyvinylidene fluoride (PVDF) layers were laminated together to form the cantilevered flow-sensing elements. Both the ALL canal system and its superficial counterpart were characterized using a dipole vibration source. Experimental results showed that the peak frequencies of both the canal and superficial sensors were approximately 110 Hz, which was estimated to be the resonance frequency of the cantilevered flow-sensing element. The proposed ALL canal system demonstrated high-pass filtering capabilities to attenuate low-frequency stimulus and a pressure gradient detection limit of approximately 11 Pa/m at a frequency of 115 ± 1 Hz. Because of its structural flexibility and noise immunity, the proposed ALL canal system shows significant potential for underwater robotics applications.

    Full Text Available Objective: To assess the effect of lining material (cement of Nubaria canal (Beheira Governorate, Egypt on its water quality. Methods: Trace metal ions (Fe, Zn, Cu, Pb, and Cd and bacterial indictors for water samples collected from two types of stations (lined and unlined during successive four seasons were analyzed. The effect of lining on bacterial indicators; total viable bacterial count at 22 and 37 °C, total coliform, fecal coliform and fecal streptococci and presence of some bacterial species were studied. Results: Bacterial indicators and trace metals showed seasonal variations, where the highest values were recorded during summer. A significant reduction for Cu (P < 0.05, Zn (P < 0.01 and Cd (P < 0.001 was recorded in lined stations compared to those of unlined ones. Bacterial indicators recorded the lowest counts in lined stations during all seasons, while there was a significant reduction (P < 0.05 between total coliform values (1.70 ± 0.50 in lined stations and unlined ones (3.57 ± 1.01 during summer. Escherichia coli bacteria were predominant in water samples of Nubaria canal, where it recorded 34.4% of bacterial isolates. Conclusions: Lined material plays a role for reducing the bacterial growth and metals concentration, therefore the lining of canal helps in preventing the discharge of sewage pollution into canal.

    The current study collected the first quantitative data on lateral line pore squamation patterns in sharks and assessed whether divergent squamation patterns are similar to experimental models that cause reduction in boundary layer turbulence. In addition, the hypothesis that divergent orientation angles are exclusively found in fast-swimming shark species was tested. The posterior lateral line and supraorbital lateral line pore squamation of the fast-swimming pelagic shortfin mako shark Isurus oxyrinchus and the slow-swimming epi-benthic spiny dogfish shark Squalus acanthias was examined. Pore scale morphology and pore coverage were qualitatively analysed and compared. In addition, pore squamation orientation patterns were quantified for four regions along the posterior lateral line and compared for both species. Isurus oxyrinchus possessed consistent pore scale coverage among sampled regions and had a divergent squamation pattern with multiple scale rows directed dorsally and ventrally away from the anterior margin of the pore with an average divergent angle of 13° for the first row of scales. Squalus acanthias possessed variable amounts of scale coverage among the sampled regions and had a divergent squamation pattern with multiple scale rows directed ventrally away from the anterior margin of the pore with an average angle of 19° for the first row of scales. Overall, the squamation pattern measured in I. oxyrinchus fell within the parameters used in the fluid flow analysis, which suggests that this pattern may reduce boundary layer turbulence and affect lateral line sensitivity. The exclusively ventral oriented scale pattern seen in S. acanthias possessed a high degree of divergence but the pattern did not match that of the fluid flow models. Given current knowledge, it is unclear how this would affect boundary layer flow. By studying the relationship between squamation patterns and the lateral line, new insights are provided into sensory biology that warrant

  19. Determination of object position, vortex shedding frequency and flow velocity using artificial lateral line canals.

    Science.gov (United States)

    Klein, Adrian; Bleckmann, Horst

    2011-01-01

    The lateral line system of fish consists of superficial neuromasts, and neuromasts embedded in lateral line canals. Lateral line neuromasts allow fish to sense both minute water motions and pressure gradients, thereby enabling them to detect predators and prey or to recognize and discriminate stationary objects while passing them. With the aid of the lateral line, fish can also sense vortices caused by an upstream object or by undulatory swimming movements of fish. We show here that artificial lateral line canals equipped with optical flow sensors can be used to detect the water motions generated by a stationary vibrating sphere, the vortices caused by an upstream cylinder or the water (air) movements caused by a passing object. The hydrodynamic information retrieved from optical flow sensors can be used to calculate bulk flow velocity and thus the size of the cylinder that shed the vortices. Even a bilateral sensor platform equipped with only one artificial lateral line canal on each side is sufficient to determine the position of an upstream cylinder.

    2016-10-01

    The relatively simple structural organization of the cranial lateral line system of bony fishes provides a valuable context in which to explore the ways in which variation in post-embryonic development results in functionally distinct phenotypes, thus providing a link between development, evolution, and behavior. Vital fluorescent staining, histology, and scanning electron microscopy were used to describe the distribution, morphology, and ontogeny of the canal and superficial neuromasts on the head of two Lake Malawi cichlids with contrasting lateral line canal phenotypes (Tramitichromis sp. [narrow-simple, well-ossified canals with small pores] and Aulonocara stuartgranti [widened, more weakly ossified canals with large pores]). This work showed that: 1) the patterning (number, distribution) of canal neuromasts, and the process of canal morphogenesis typical of bony fishes was the same in the two species, 2) two sub-populations of neuromasts (presumptive canal neuromasts and superficial neuromasts) are already distinguishable in small larvae and demonstrate distinctive ontogenetic trajectories in both species, 3) canal neuromasts differ with respect to ontogenetic trends in size and proportions between canals and between species, 4) the size, shape, configuration, physiological orientation, and overall rate of proliferation varies among the nine series of superficial neuromasts, which are found in both species, and 5) in Aulonocara, in particular, a consistent number of canal neuromasts accompanied by variability in the formation of canal pores during canal morphogenesis demonstrates independence of early and late phases of lateral line development. This work provides a new perspective on the contributions of post-embryonic phases of lateral line development and to the generation of distinct phenotypes in the lateral line system of bony fishes.

    Two of five scalloped hammerhead sharks (Sphyrna lewini) captured May 1987 in Hawaii (USA) developed granulomatous exudative mycotic dermatitis localized in the lateral line canal system. The lesion initially was noted in the cephalic canals, but over a period of months extended into the lateral canal. Fusarium solani and Vibrio spp. were isolated from the canal exudate of both sharks. Bacterial colonies were not observed in the canal walls or surrounding tissues. Fusarium solani infection resulted in a chronic physical and behavioral deterioration of the two sharks; one shark was euthanized in September 1988 and the other in July 1989. This is the first report of Fusarium solani infection in the lateral line canal system and the third account in hammerhead sharks.

  2. Identification of dental root canals and their medial line from micro-CT and cone-beam CT records.

    Shape of the dental root canal is highly patient specific. Automated identification methods of the medial line of dental root canals and the reproduction of their 3D shape can be beneficial for planning endodontic interventions as severely curved root canals or multi-rooted teeth may pose treatment challenges. Accurate shape information of the root canals may also be used by manufacturers of endodontic instruments in order to make more efficient clinical tools. Novel image processing procedures dedicated to the automated detection of the medial axis of the root canal from dental micro-CT and cone-beam CT records are developed. For micro-CT, the 3D model of the root canal is built up from several hundred parallel cross sections, using image enhancement, histogram based fuzzy c-means clustering, center point detection in the segmented slice, three dimensional inner surface reconstruction, and potential field driven curve skeleton extraction in three dimensions. Cone-beam CT records are processed with image enhancement filters and fuzzy chain based regional segmentation, followed by the reconstruction of the root canal surface and detecting its skeleton via a mesh contraction algorithm. The proposed medial line identification and root canal detection algorithms are validated on clinical data sets. 25 micro-CT and 36 cone-beam-CT records are used in the validation procedure. The overall success rate of the automatic dental root canal identification was about 92% in both procedures. The algorithms proved to be accurate enough for endodontic therapy planning. Accurate medial line identification and shape detection algorithms of dental root canal have been developed. Different procedures are defined for micro-CT and cone-beam CT records. The automated execution of the subsequent processing steps allows easy application of the algorithms in the dental care. The output data of the image processing procedures is suitable for mathematical modeling of the central line. The

    OBJECTIVE Grabb's line-the perpendicular distance from the basion-C2 line (pB-C2)-is a widely used radiographic measurement with significant clinical implications in patients with a complex Chiari malformation. Rigorous demonstration of the reproducibility of this measurement has not previously been reported. The authors report a standardized measurement technique with excellent inter- and intrarater reliability on T1-weighted sagittal MRI. METHODS The authors developed a standardized measurement technique that included specifications of midline slice selection, landmark and reference line definitions, and measurement technique on T1-weighted sagittal images. Twenty MR images were reviewed by 2 pediatric neurosurgeons, 1 pediatric radiologist, and 1 undergraduate student. Measurements were performed using the technique specified on 2 separate occasions. Intrarater and interrater reliabilities were calculated using the intraclass correlation coefficient. RESULTS A combined interrater reliability of 0.879 was achieved for the pB-C2, and 0.916 for the clival-canal angle, another measure of interest in patients with complex Chiari malformations. Intrarater reliability for these measurements exceeded 0.858 for all 4 reviewers. CONCLUSIONS Grabb's line-the pB-C2-can be measured with excellent reliability using a standardized measurement protocol. Individual clinicians and collaborative databases should consider using validated measurement techniques to guide clinical decision making in patients with craniocervical junction pathology.

    Full Text Available Alternative dispute resolution (ADR includes dispute resolution processes and techniques that act as a means for disagreeing parties to come to an agreement short of litigation. It is a collective term for the ways that parties can settle disputes, with (or without the help of a third party. Despite historic resistance to ADR by many popular parties and their advocates, ADR has gained widespread acceptance among both the general public and the legal profession in recent years. In fact, some courts now require some parties to resort to ADR of some type, before permitting the parties' cases to be tried. The rising popularity of ADR can be explained by the increasing caseload of traditional courts, the perception that ADR imposes fewer costs than litigation, a preference for confidentiality, and the desire of some parties to have greater control over the selection of the individual or individuals who will decide their dispute. Directive 2013/11/EU of the European Parliament and of the Council on alternative dispute resolution for consumer disputes and amending Regulation (EC No 2006/2004 and Directive 2009/22/EC (hereinafter „Directive 2013/11/EU” aims to ensure a high level of consumer protection and the proper functioning of the internal market by ensuring that complaints against traders can be submitted by consumers on a voluntary basis, to entities of alternative disputes which are independent, impartial, transparent, effective, simple,quick and fair. Directive 2013/11/EU establishes harmonized quality requirements for entities applying alternative dispute resolution procedure (hereinafter "ADR entity" to provide the same protection and the same rights of consumers in all Member States.

    Full Text Available This essay will examine the process of boundary dispute and definition between Guatemala and Mexico after 1821. The disagreement and negotiations over limits between countries revealed the wide-reached interest in delineation of national territories, fundamental for the formation of independent nation-states. Several ideological and economic factors affected the dispute and the final boundary treaty between Guatemala and Mexico. An important ideological influence played the nineteenth-century romantic nationalism, which made the Creole elites to establish particular and unique national entities. Moreover, the worldwide drive to map the earth‘s surface by using tools of the modern cartographic science played an important role in the process of Mexican-Guatemalan boundary definition. The postcolonial expansion of agro-export economy in Central America, and especially the coffee boom starting in the Mexican southeastern and Guatemalan western borderlands from the second half of the nineteenth century onward became an economic stimulus for boundary definition process. This is the historical context, in which Mexican and Guatemalan elites were engaged in a long-running debate and negotiations over the common border.

    The present study investigated the effect of the Iodoform-containing root canal filling material on the viability of cultured macrophages and epithelial cells, and on cytokine secretion. The effect of Endoflas F.S. on the proliferation of a RAW 264.7 macrophage cell line and on a RKO epithelial cell line, and on the production of tumour necrosis factor alpha (TNFα) from macrophages was examined. Cell vitality was evaluated using a colourimetric XTT (sodium 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)-carbonyl]-2H-tetrazolium inner salt) assay. The presence of cytokines was determined by two-site enzyme-linked immunosorbent assay (ELISA). Direct exposure of Endoflas F.S. and its media, up to a dilution of 1/8, decreased the viability of macrophages and epithelial cells by ∼70% compared to control media (Pmaterial. Direct and indirect exposure to high concentrations of iodoform-containing root canal filling material showed a cytotoxic effect on macrophages and epithelial cells, while low concentrations induced cell proliferation.

    Construction work on the civil engineering contract started at Point 5 in August 1998. The new surface buildings and underground structures are necessary to accommodate the CMS detector for the LHC Project. The principal underground works consist of two new shafts, two parallel caverns separated by a supporting pillar, and a number of small connection tunnels and service galleries. A dispute resolution procedure has been included in the contract, whereby a Panel of Adjudicators may be called upon to make a decision in the case of a difference or dispute between the parties. The aim of this paper is to present CERN's first experience of civil engineering Adjudication arising from problems encountered with the ground freezing technique employed to allow construction of two new shafts.

    1990-01-01

    This paper presents an X-ray scheme for calculating the depth of pterygoid canals required for accurate tomography. The scheme includes three lines: line A corresponds to the physiological horizontal line, line B is drawn, normally to line A through the tip of the nose, and line C is the perpendicular from line B to the upper third of the posterior wall of the pterygopalatine fossa. The length of line B plus 1 cm (thickness of external nose soft tissues) is the value to be determined. Twenty-six patients underwent X-ray examinations by an EDK-750B unit (70 kV, 150 mA, 1.65 s). In all cases 1-3 images were sufficient to obtain good visualization of the pterygoid canals.

    Full Text Available The activity of administrative bodies includes big numbers of various acts and actions, through which the will of public administration is formed. The will of public administration bodies, expressed in administrative individual and normative acts, in administrative contracts and real acts, finds its reflection in the Constitution, laws and other provisions of legal character. All this activity is not inerrant and therefore, it is not uncontrollable. The supervision of executive activity is subject to political control of administrative acts through authorities designated for this purpose, as well as internal control and the judicial control. The institution of judicial control of administrative acts and actions appears as very important and widely treated in the legal doctrine. The protection of constitutional and legal rights of private persons is accomplished by subjecting administrative activity both to internal administrative control, as well as to the judicial control in accordance with legal provisions. The judicial control of administrative acts represents a constitutional guarantee for citizens to protect their rights through public and fair trial by an independent and impartial court. In this way, the Constitution empowers the common administrative court that invalidates an action or administrative act, but not all administrative acts may be subject to administrative dispute, with the exception of cases against which the administrative conflict cannot be carried out (negative enumeration.

    2017-08-01

    The purpose of this study was to investigate the relationships between the location of the mental foramen (MF) and the mandibular canal (MC) and the surgical access line (SAL) of the mandibular posterior teeth using cone-beam computed tomographic (CBCT) scans. CBCT scans of 204 subjects ranging in age from 18-76 years old were evaluated. The vertical and horizontal distances from the MF to the SAL of the mandibular premolars and first molars and the vertical distance from the MC to the SAL of the second premolars and first molars were measured via CBCT scans. The average vertical distance between the MF and the SALs showed significant increases sequentially from the first premolars to the distal roots of the first molars, and the shortest average distance of 2.74 mm was obtained for the first premolars. The SALs of the second premolars were the closest to the MF in the horizontal direction with an average distance of 1.5 mm. In 19.9% of the cases, the vertical and horizontal distances between the MF and the SALs of the second premolars were less than 2 mm. In addition, the MF was located superior to the root apices in 6.62% of the cases. The majority of the SALs were located at a vertical distance from the MC that was more than 2 mm. Men and women exhibited significant differences in both the horizontal distance from the MF to the SALs of the first premolars and the vertical distance from the MC to the SALs of the second premolars. To improve the success of endodontic microsurgery, adequate knowledge of the anatomic relationships between the location of the MF and MC and the SAL of the mandibular posterior teeth is indispensable to surgeons.

  3. Drag force acting on a neuromast in the fish lateral line trunk canal. I. Numerical modelling of external-internal flow coupling.

    Science.gov (United States)

    Barbier, Charlotte; Humphrey, Joseph A C

    2009-07-06

    Fishes use a complex, multi-branched, mechanoreceptive organ called the lateral line to detect the motion of water in their immediate surroundings. This study is concerned with a subset of that organ referred to as the lateral line trunk canal (LLTC). The LLTC consists of a long tube no more than a few millimetres in diameter embedded immediately under the skin of the fish on each side of its body. In most fishes, pore-like openings are regularly distributed along the LLTC, and a minute sensor enveloped in a gelatinous cupula, referred to as a neuromast, is located between each pair of pores. Drag forces resulting from fluid motions induced inside the LLTC by pressure fluctuations in the external flow stimulate the neuromasts. This study, Part I of a two-part sequence, investigates the motion-sensing characteristics of the LLTC and how it may be used by fishes to detect wakes. To this end, an idealized geometrical/dynamical situation is examined that retains the essential problem physics. A two-level numerical model is developed that couples the vortical flow outside the LLTC to the flow stimulating the neuromasts within it. First, using a Navier-Stokes solver, we calculate the unsteady flow past an elongated rectangular prism and a fish downstream of it, with both objects moving at the same speed. By construction, the prism generates a clean, periodic vortex street in its wake. Then, also using the Navier-Stokes solver, the pressure field associated with this external flow is used to calculate the unsteady flow inside the LLTC of the fish, which creates the drag forces acting on the neuromast cupula. Although idealized, this external-internal coupled flow model allows an investigation of the filtering properties and performance characteristics of the LLTC for a range of frequencies of biological interest. The results obtained here and in Part II show that the LLTC acts as a low-pass filter, preferentially damping high-frequency pressure gradient oscillations, and

    The courts have provided the traditional battleground for conflicts between environmental interest groups and those whose actions in some way have an adverse impact on the environment The judicial process is a time-consuming one in which all sides usually must concede to some points. Environmental disputes involve complex scientific issues which the court system is not set up to comprehend, so that the process gives the parties to a dispute the sense of having lost control of their own destinies. An increasing number of parties to environmental disputes are turning to negotiation, or mediation, as an alternative in which they can be active parties in the settlement-making process rather than the victims of a court-imposed solution When do the parties to a dispute choose a negotiated settlement over a court battle? To what extent does each party make the concessions necessary to reach an agreement? These questions can be answered by the game theory that provides a model for analyzing the negotiation process. This paper will apply game theory to two environmental conflict cases A series of questions pertinent to the analysis of all environmental disputes will be raised

    Immunoglobulin-like domain containing receptor 1 (ILDR1) is a poorly characterized gene that was first identified in lymphoma cells. Recently, ILDR1 has been found to be responsible for autosomal recessive hearing impairment DFNB42. Patients with ILDR1 mutations cause bilateral non-progressive moderate-to-profound sensorineural hearing impairment. However, the etiology and mechanism of ILDR1-related hearing loss remains to be elucidated. In order to uncover the pathology of DFNB42 deafness, we used the morpholino injection technique to establish an ildr1b-morphant zebrafish model. Ildr1b-morphant zebrafish displayed defective hearing and imbalanced swimming, and developmental delays were seen in the semicircular canals of the inner ear. The gene expression profile and real-time PCR revealed down-regulation of atp1b2b (encoding Na(+)/K(+) transporting, beta 2b polypeptide) in ildr1b-morphant zebrafish. We found that injection of atp1b2b mRNA into ildr1b-knockdown zebrafish could rescue the phenotype of developmental delay of the semicircular canals. Moreover, ildr1b-morphant zebrafish had reduced numbers of lateral line neuromasts due to the disruption of lateral line primordium migration. In situ hybridization showed the involvement of attenuated FGF signaling and the chemokine receptor 4b (cxcr4b) and chemokine receptor 7b (cxcr7b) in posterior lateral line primordium of ildr1b-morphant zebrafish. We concluded that Ildr1b is crucial for the development of the inner ear and the lateral line system. This study provides the first evidence for the mechanism of Ildr1b on hearing in vivo and sheds light on the pathology of DFNB42. © The Author 2014. Published by Oxford University Press.

The two books under review here demonstrate some of the diversity of writing within the discipline of international relations. In China’s Troubled Waters: Maritime Disputes in Theoretical Perspectives, political scientist Steve Chan, following Kant, describes his style as “nomothetic,” “which emphasizes attention to classes of events rather than specific episodes” (vii. Strategic and defense studies scholar Do Thanh Hai’s Vietnam and the South China Sea: Politics, Security and Legality is an example of what Chan calls the “idiographic approach,” focusing “on the more unique or specific aspects of the situation” (vii. Chan wants to be able to generalize and compare, and he explicitly eschews narratives of “who did what to whom.” Hai, on the other hand, is keen to make clear that it is China who did something to Vietnam. The most obvious criticism to make of his book is that it is written from an overtly Vietnamese perspective. That is a weakness, but also potentially a draw for those interested in the formulation of Vietnamese policy. Chan writes from an ostensibly neutral position, but, as we shall see, his analysis is rooted within a Chinese world view.

    Full Text Available In this article author studies issues of resolving civil disputes in the People's Republic of China. Author notes that earlier, if the dispute concerns individuals or legal entities, administrative powers or affected rights and legitimate interests, as a rule such disputes were not considered by arbitration courts. But now there is a tendency that if the dispute concerns the basic rights and obligations, then it can be divided into different parts and determine what can be resolved by arbitration. In conclusion, the author notes that at present there are several points of view regarding the resolution of civil disputes in arbitration. On the one hand, there is an opinion that arbitration (the arbitral tribunal is not in a position to strictly follow the legislation and, therefore, the interests of the parties may be threatened. On the other hand, it is considered that arbitration as an existing form of dispute settlement is initially nonclassical and when choosing this type there is no need for full compliance with legal procedures, therefore, the arbitrator can justify his decision based on his own experience, conscience and justice. Thus, the most effective and used mechanism for resolving civil disputes in China is arbitration.

    Full Text Available This article studies the latest trends observed in the area of contradictory relations between countries with regard to international trade, which cause changes in the paradigm of international trade disputes. It has been found out that any state of inconsistent relations between the countries is recently characterized as a «trade war». It has been analyzed the notions of «dispute», «conflict», «war» according to international regulatory documents and determined the applicability of these terms depending on a number of criteria. It has been studied the evolution of the objects of international trade disputes since the time of ancient Greece until today, and new trends based on this have been revealed with regard to use of trade policy instruments that cause disputes between countries. Several specific examples of international trade disputes and causes of their occurrence have been considered. A quantitative analysis of international trade disputes in general and in relations between the leading countries in terms of a number of the trade disputes in which they were involved has been performed.

During the first few years in work of new established Administrative Court in Republic of Serbia, jurisprudence was completely corresponded to all legal rules in advocating of the parties in this type of dispute. However, with the gradualy increasing number of oral hearings, which are still, unfortunately, exception rather than rule, we notice the existence of a certain deviation from the legal rules, which is reflected in giving opportunities Attorney's Office to represent the defendant authority as a party to the hearing, although when the subject of dispute is not violation of any property rights of the state, autonomous province or local self-government, which is primary competence of Attorney's Office. The main problem in this occurrence is that the point of representation of organs, as decision making authorities, by Attorney's Office, is in a greater protection of property interests of territorial communities, but on this way, it is only creating additional costs of an administrative dispute, which in the case of loss of the dispute, falling on the burden of the citizens as a prosecutor, and go directly to the budget of the relevant territorial community. Therefore, in order to create legal certainty and the protection of citizens property interests, it is necessary to discontinue with this practice and representation of the parties in this type of disputes start to exercise according to legal rules, which for the competent Attorney's Office provide opportunity to participate in any administrative dispute when it considers that some administrative act violated property rights and interests of some of territorial communities.

    Full Text Available The perception of elements in a system often creates their interdependence, interconditionality, and suppression. The lines from a basic geometrical element have become the model of a reductive world based on isolation according to certain criteria such as function, structure, and social organization. Their traces are experienced in the contemporary world as fragments or ruins of a system of domination of an assumed hierarchical unity. How can one release oneself from such dependence or determinism? How can the lines become less “systematic” and forms more autonomous, and less reductive? How is a form released from modernistic determinism on the new controversial ground? How can these elements or forms of representation become forms of action in the present complex world? In this paper, the meaning of lines through the ideas of Le Corbusier, Leonidov, Picasso, and Hitchcock is presented. Spatial research was made through a series of examples arising from the projects of the architectural studio “Residential Transformations”, which was a backbone for mapping the possibilities ranging from playfulness to exactness, as tactics of transformation in the different contexts of the contemporary world.

    The report sets out lessons learned while carrying out the study. It concludes that genetic disputes will increase in number and that ADR processes including mediation, arbitration, the use of independent experts and court-appointed masters can be helpful in resolving them. It suggests additional effort on bioremediation, and workplace disputes and training for ADR neutrals.

  10. Industrial Disputes in the Construction Sector

    2012-11-01

    Full Text Available The Cole Royal Commission enquiry into the building and construction (abbreviated to ‘construction’ sector recommended controversial workplace-relation reforms for that sector. The recommended changes are likely to be enshrined in legislation within the year. The Commission drew on analyses of industrial disputes that focused, in the main, on quite recent experience. This paper attempts to give a broader historical perspective on disputes in that sector by considering the pattern of disputes for the entire post-World War II period. Accordingly, data on disputes and employees during the entire period are gathered from Australian Bureau of Statistics current and archived sources. These data are classified according to sector (construction versus non-construction and analysed. It is found that the strike rate has, on average, been greater in the construction sector than in the non-construction sector. However, there have been periods during which disputes in the construction sector have been relatively low. The most recent period was during the period of the Accord (1983-96, during which the strike rate in the construction sector fell relatively strongly. The analysis of this relatively broad historical period draws attention, among other things, to the possibility that the sort of strategies employed during the Accord years – strategies of cooperation and consensus building – may provide a more effective means of bringing industrial peace to the workplace relations scene of the construction sector than policies that are relatively confrontational.

    2014-03-01

    The China Grand Canal is one of the earliest canals in the world, having lasted for nearly 3000 years. Even its section canals have a rich history, such as the North-South Grand Canal that was established during the Sui Dynasty, whereas the Beijing-Hangzhou Canal was excavated during the Yuan Dynasty and the east line of the South-to-North Water Diversion. As one of the longest in the world, the China Grand Canal's total length is over 3500 kilometers. This length includes the navigable, unnavigable, and underground sections. Making the best use of situations and according to local conditions, the Chinese people harmoniously constructed the Beijing-Hangzhou Canal with nature. Tens of millions of workers took nearly 3000 years to complete the great shipping system. Navigable sections still exist for up to 900 kilometers and the volume of freight traffic is approximately 300 million tons. The canal remains the main logistical channel of the North-to-South Coal Transportation, South-to-North Water Diversion, and resources circulation. To date, China is promoting the success of heritage application. Part of these efforts is the declaration of the China Grand Canal as a World Cultural Heritage by 2014. In addition, the east route of the South-to-North Water Transfer project is planned to be navigable by 2016. The ancient Beijing-Hangzhou Grand Canal will usher in the new ecological civilization and cultural revival along the canal. This paper presents technical methods of water environment evolution research on the river system, river, and water quality along the Beijing-Hangzhou Canal through the integration of historical literature and modern remote sensing image data. The study carried out water environment investigation and analysis along the Beijing-Hangzhou canal by using ETM, SPOT image data, and GPS measurement data.

  3. Dispute Resolution through Third Party Mediation: Malaysia and Indonesia

    2007-12-01

    Full Text Available Abstract: Since independence, Malaysia has been involved in territorial disputes and overlapping maritime claims with almost all its neighbours. Some of these disputes were resolved through bilateral and multilateral treaties. However, Malaysia and Indonesia settled the dispute over Sipadan-Ligitan islands by referring the issue to the International Court of Justice (ICJ. This high sense of civility shown by the two countries need to be analysed and appreciated. Documentary analysis shows that the consideration of the geopolitical conditions, the state of bilateral relations the disputing countries were enjoying, security problems, the lack of progress in settling disputes through the bilateral efforts and the weaknesses inherent in ASEAN’s dispute settlement mechanism made the two parties to refer their dispute to the ICJ rather than to the ASEAN High Council (AHC. The ICJ’s decision, delivered in 2002, was accepted by the two parties as stipulated in the referral agreement.

According to a survey conducted by the Taiwan Network Information Center, the on-line game is one of the most popular amusements among those activities. Due to the trend of playing on-line games, many legal disputes are inevitably invoked on the Internet. Firstly, we have to think about how to adjust legal rules or to enact new statutes and then applying them to Cyberspace. In order to deal with those disputes, the Legislative Yuan enacted the whole new Chapter of Criminal Code, Crimes of Disrupting Computer Usages, on June 3, 2003. However, there should be a gap between the law in books and law in action. For the purpose of examining whether the objects of law are fulfilled or not, we should not only be focusing on the logical procedure of legal tradition, but also excising a new approach, economic analysis of law, to evaluate the effects of the new statute and, in addition, to provide a different point of view for judges and other legal enforcement agents to elaborate the new law. For the sake of resolving on-line disputes by the new statute, this article will analyze the issue through cost-benefit module based on economic analysis. The point here is how to increase the cost of committing the perpetration that would keep a ration and self-interest person away from the wrongdoing act. Furthermore, the benefit of increasing the cost of perpetration would decrease the cost of legal enforcement

    Dispute settlement over groundwater issues is hampered by the fact that groundwater is not discussed in existing bilateral treaties between Mexico and the United States whereas aquifers frequently span the border zone. Accurate, international data on groundwater resources and dynamics are therefore needed to assist formulation of bi-national groundwater policy, particularly in the Colorado River delta region. We will present our preliminary InSAR (Interferometric Synthetic Aperture Radar) measurements of cm-scale vertical displacements of the surface above the Mexicali Valley aquifer/ Mesa d'Andrade, using these as a proxy for aquifer depletion and recharge events. It is anticipated that this InSAR monitoring will allow characterization of aquifer behavior across the border zone over the past decade, and prior to (or during) the planned lining of the All-American Canal and the federal reductions in Colorado River surface water allocations to urban and/or rural California consumers. Either action could seriously alter a major aquifer recharge zone and, consequently, groundwater volumes in Mexico (655 private and federal pumping sites) and southeastern California. We will present preliminary deformation maps for a roughly 650 km2 area of the Mexicali-Calexico region; a first step in characterizing regional and local `pre-lining' subsidence signals due to groundwater pumping, geothermal energy operations, tectonic creep and, possibly, changes in soil properties.

    Full Text Available Indicators that rank countries according socioeconomic measurements are important tools for regional development and political reform. Those currently in widespread use are sometimes criticized for a lack of reproducibility or the inability to compare values over time, necessitating simple, fast and systematic measures. Here, we applied the 'guilt by association' principle often used in biological networks to the information network within the online encyclopedia Wikipedia to create an indicator quantifying the degree to which pages linked to a country are disputed by contributors. The indicator correlates with metrics of governance, political or economic stability about as well as they correlate with each other, and though faster and simpler, it is remarkably stable over time despite constant changes in the underlying disputes. For some countries, changes over a four year period appear to correlate with world events related to conflicts or economic problems.

    Full Text Available Labor disputes can be small or large, individual or collective, refer to a particular job or lie in more than one enterprise. The causes of these disputes are numerous and diverse, ranging from a simple appeal of one individual employee for the right of compensation, in a collective complaint of the employees about the unsafe or unhealthy conditions of work, or termination of work by all employees in a workplace, claiming that they are prevented from setting up a union to protect their interests. The product of this process is a binding agreement for its implementation and is the result of ongoing cooperation between employees and employers based on consensual decision. Organizations of employees are important actors of collective conflict resolution procedures of labor relations, and particularly those held in the offices of reconciliation, should revitalize their role.

    The overwhelming majority of intellectual property lawsuits settle before trial. These settlements involve agreements between the patentee and the accused infringer, parties who are often competitors before the lawsuit. Because these competitors may agree to stop competing, to regulate the price each charges, and to exchange information about products and prices, settlements of intellectual property disputes naturally raise antitrust concerns. In this paper, we suggest a way to reconcile the ...

    We wanted to report the CT image findings of the osteoma of the external auditory canal. Temporal bone CT scanning was performed on eight patients (4 males and 4 females aged between 8 and 41 years) with pathologically proven osteoma of the external auditory canal after operation, and the findings of the CT scanning were retrospectively reviewed. Not only did we analyze the size, shape, distribution and location of the osteomas, we also analyzed the relationship between the lesion and the tympanosqumaous or tympanomastoid suture line, and the changes seen on the CT scan images for the patients who were able to undergo follow-up. All the lesions of the osteoma of the external auditory canal were unilateral, solitary, pedunculated bony masses. In five patients, the osteomas occurred on the left side and for the other three patients, the osteomas occurred on the right side. The average size of the osteoma was 0.6 cm with the smallest being 0.5 cm and the largest being 1.2 cm. Each of the lesions was located at the osteochondral junction in the terminal part of the osseous external ear canal. The stalk of the osteoma of the external auditory canal was found to have occurred in the anteroinferior wall in five cases (63%), in the anterosuperior wall (the tympanosqumaous suture line) in two cases (25%), and in the anterior wall in one case. The osteoma of the external auditory canal was a compact form in five cases and it was a cancellous form in three cases. One case of the cancellous form was changed into a compact form 35 months later due to the advanced ossification. Osteoma of the external auditory canal developed in a unilateral and solitary fashion. The characteristic image findings show that it is attached to the external auditory canal by its stalk. Unlike our common knowledge about its occurrence, osteoma mostly occurred in the tympanic wall, and this is regardless of the tympanosquamous or tympanomastoid suture line.

    2012-01-01

    Full Text Available Dilaceration is the result of a developmental anomaly in which there has been an abrupt change in the axial inclination between the crown and the root of a tooth. Dilaceration can be seen in both the permanent and deciduous dentitions, and is more commonly found in posterior teeth and in maxilla. Periapical radiographs are the most appropriate way to diagnose the presence of root dilacerations. The controlled regularly tapered preparation of the curved canals is the ultimate challenge in endodontics. Careful and meticulous technique will yield a safe and sufficient enlargement of the curved canals. This article gives a review of the literature and three interesting case reports of root dilacerations.

  16. The circulation of the cerebrospinal fluid (CSF) in the spinal canal

    Science.gov (United States)

    Sanchez, Antonio L.; Martinez-Bazan, Carlos; Lasheras, Juan C.

    2016-11-01

    Cerebrospinal Fluid (CSF) is secreted in the choroid plexus in the lateral sinuses of the brain and fills the subarachnoid space bathing the external surfaces of the brain and the spinal canal. Absence of CSF circulation has been shown to impede its physiological function that includes, among others, supplying nutrients to neuronal and glial cells and removing the waste products of cellular metabolism. Radionuclide scanning images published by Di Chiro in 1964 showed upward migration of particle tracers from the lumbar region of the spinal canal, thereby suggesting the presence of an active bulk circulation responsible for bringing fresh CSF into the spinal canal and returning a portion of it to the cranial vault. However, the existence of this slow moving bulk circulation in the spinal canal has been a subject of dispute for the last 50 years. To date, there has been no physical explanation for the mechanism responsible for the establishment of such a bulk motion. We present a perturbation analysis of the flow in an idealized model of the spinal canal and show how steady streaming could be responsible for the establishment of such a circulation. The results of this analysis are compared to flow measurements conducted on in-vitro models of the spinal canal of adult humans.

    Park, Ellen; Chehroudi, Babak; Coil, Jeffrey M

    2014-05-01

    This study examined the effect of the access size and straight-line path of access on third-year dental students' ability to locate a second mesiobuccal (MB2) canal in maxillary first and second molars. One hundred and six third-year dental students at one Faculty of Dentistry performed simulated root canal treatment with the aid of 2x magnification loupes on extracted teeth. A postgraduate endodontic student subsequently made a reasonable search for an untreated MB2 canal with the aid of a dental operating microscope. The mesiobuccal roots were then sectioned horizontally for determination of the canal configuration. The dental students were able to treat an MB2 canal in 15.8 percent of the teeth, but this was not associated with satisfactory access criteria. The postgraduate endodontic student identified an MB2 canal in 54.7 percent of the remaining tooth samples excluding those where the MB2 canal was found by the dental students; this represented 94.3 percent of those teeth confirmed by horizontal sectioning of the root to have an MB2 canal. The postgraduate student troughed, on average, 2.6 mm before negotiating the MB2 canal. As satisfactory access criteria and straight-line path of access did not correlate with the dental students' ability to find a second mesiobuccal canal, this result has important implications for educational goals with respect to endodontic treatment of maxillary molar teeth.

  1. Analysis of sedimentation of canals

    Directory of Open Access Journals (Sweden)

    Agunwamba, J.C.,

    2013-03-01

    Full Text Available The dredged canals in the Niger Delta coastal flood plain are being threatened by siltation. This study is limited to those canals in Rivers State of Nigeria, which are under the influence of tidal waves. A total of eight canals were considered with four each from Ekulama and Cawthorne Channel. Different approaches were used to carry out this study, which includes field reconnaissance survey, hydrographic survey, soil sample analysis and collection of all available data and information. The typical bed materials size (D50 is approximately 0.01mm; which gives a settling velocity of 0.09mm/sec using stroke’s law. Hydrographic survey of the canals from 1992 to 1996 revealed an average siltation rate of 2.35m/yr. A regression equation was also derived which relates the cost of dredging to canal area, rate of siltation and average aggregation. A plot of canal centre profile; entrance, middle and end cross sections showing sediment distribution along the canal profile, shows that majority of the particles that form the sediment enter the canal from the rivers. The sedimentation is caused by the reduction in water current, which has average value of 0.0145m/sec. The bathyorographical check on the canals revealed that the sum of the two exterior angles of the canal with the river at the point of connection has to lie within 1800 + 50 for an effective flow that will minimize settlement of particles. In addition, the canals should be constructed to start and terminate on a moving water body, to avoid dead ends. A regression equation was determined which relates the cost of dredging to canal area, rate of siltation and average aggradations.

Despite historic resistance, over the years ADR has gained widespread acceptance among both the general public and the legal profession. In the discussion there was a specific emphasis on mediation and arbitration. Kathrin Nitschmann, a lawyer and mediator from Saarbruecken, Germany, talked about “Professionalisation in mediation”. In addition to participation aspects she determined both the risks and the perspectives of professionalization in mediation. Luigi Cominelli, Assistant Professor of Sociology of Law at the University of Milan, Italy, reported on “Regulating Mediation in the EU”. He described the history of regulating mediation in the EU as well as domestic regulations since the beginning of modern mediation movement in the western world since the 1970s. Claude Witz, a French civil law professor at the University of Saarland, Germany, referred to “His experience in arbitration.” After highlighting some aspects of his experience, he pointed out the importance of arbitration in international commercial disputes. Alec Stone Sweet, Leitner Professor of Law, Politics, and International Studies, Yale Law School, United States, was reporting on “Arbitration and judicialization.” Initially, he presented arbitration as a triadic dispute resolution and then focused on judizialization in arbitration. Sir David Edward, former Judge of the Court of Justice of the European Communities and Professor Emeritus of the School of Law of the University of Edinburgh, United Kingdom, spoke about “The view of an arbitrator.” While elaborating on multiple reasons for ADR, he honed focus on mediation and arbitration.

    A comparison of the pattern and timing of development of cranial lateral line canals and canal neuromasts in three species of Lake Malawi cichlids, Labeotropheus fuelleborni and Metriaclima zebra (narrow lateral line canals), and Aulonocara baenschi (widened lateral line canals) was used to test the hypothesis that the evolution of widened canals (thought to be an adaptive phenotype in the lateral line system) from narrow canals is the result of heterochrony. Using histological analysis and scanning electron microscopy, this study has provided the first detailed and quantitative description of the development of widened lateral line canals in a teleost, and has demonstrated that: 1) canal neuromast number and the pattern of canal morphogenesis are conserved among species with different adult canal phenotypes, 2) heterochrony ("dissociated heterochrony" in particular) can explain the evolution of widened canals and variation in morphology between canals within a species with respect to canal diameter and neuromast size, and 3) the morphology of the lateral line canals and the dermal bones in which they are found (e.g., the mandibular canal the dentary and anguloarticular bones of the mandible) can evolve independently of each other, thus requiring the addition of another level of complexity to discussions of modularity and integration in the skull of bony fishes.

  4. Resolution of territorial disputes in international law

    Full Text Available Territorial disputes in international law are resolved by peaceful means, like negotiations, mediation, conciliation, arbitration and in the procedure at the International Court of Justice. Borders between states are, in practice, determined on the basis of the uti possidetis iuris principle and principle of effective control. Historical arguments for territorial acquisition are not generally accepted, because changes of borders have to be a result of democratically expressed will of states. Also, the right of people for self-determination was used in the process of decolonization for creating new states but it has emerged in later years like in the case of East Timor, as a legal title for gaining independence. Apart from the process of decolonization, the right to self-determination is rather unclear and disputable regarding its scope and content. Traditional modes of territorial acquisition still have decisive role in international law. Almost all states rely on them in order to substantiate their claims for possession of certain territories. Therefore, international courts and arbitrations cannot ignore them.

    1997-04-01

    Lumbar canal stenosis is an increasingly recognized condition in patients more than 65 years of age. The clinical syndrome is dominated by neurogenic claudication. The natural history of the Condition is not yet well described. Long-term results of surgical therapy are frequently disappointing, and reoperation is required in more than 10% of patients. Nonoperative treatment options include physical therapy exercise programs, calcitonin, analgesics, and epidural steroid injections. A clinical pathway for management of symptomatic stenosis, emphasizing an initial nonoperative approach, is suggested.

    The lateral line system allows elasmobranchs to detect hydrodynamic movements in their close surroundings. We examined the distribution of pit organs and lateral line canals in 4 species of sawfish (Anoxypristis cuspidata, Pristis microdon, P. clavata and P. zijsron). Pit organs could only be located in A. cuspidata, which possesses elongated pits that are lined by dermal denticles. In all 4 pristid species, the lateral line canals are well developed and were separated into regions of pored and non-pored canals. In all species the tubules that extend from pored canals form extensive networks. In A. cuspidata, P. microdon and P. clavata, the lateral line canals on both the dorsal and ventral surfaces of the rostrum possess extensively branched and pored tubules. Based on this morphological observation, we hypothesized that these 3 species do not use their rostrum to search in the substrate for prey as previously assumed. Other batoids that possess lateral line canals adapted to perceive stimuli produced by infaunal prey possess non-pored lateral line canals, which also prevent the intrusion of substrate particles. However, this hypothesis remains to be tested behaviourally in pristids. Lateral line canals located between the mouth and the nostrils are non-pored in all 4 species of sawfish. Thus this region is hypothesized to perceive stimuli caused by direct contact with prey before ingestion. Lateral line canals that contain neuromasts are longest in P. microdon, but canals containing neuromasts along the rostrum are longest in A. cuspidata. Copyright © 2011 S. Karger AG, Basel.

    Spinal stenosis is a narrowing of the spinal canal by a combination of bone and soft tissues, which can lead to mechanical compression of spinal nerve roots or the dural sac. The lumbal spinal compression of these nerve roots can be symptomatic, resulting in weakness, reflex alterations, gait disturbances, bowel or bladder dysfunction, motor and sensory changes, radicular pain or atypical leg pain and neurogenic claudication. The anatomical presence of spinal canal stenosis is confirmed radiologically with computerized tomography, myelography or magnetic resonance imaging and play a decisive role in optimal patient-oriented therapy decision-making. (orig.) [German] Die Spinalkanalstenose ist eine umschriebene, knoechern-ligamentaer bedingte Einengung des Spinalkanals, die zur Kompression der Nervenwurzeln oder des Duralsacks fuehren kann. Die lumbale Spinalkanalstenose manifestiert sich klinisch als Komplex aus Rueckenschmerzen sowie sensiblen und motorischen neurologischen Ausfaellen, die in der Regel belastungsabhaengig sind (Claudicatio spinalis).

    Full Text Available Abstract Complete atrioventricular canal (CAVC, also referred to as complete atrioventricular septal defect, is characterised by an ostium primum atrial septal defect, a common atrioventricular valve and a variable deficiency of the ventricular septum inflow. CAVC is an uncommon congenital heart disease, accounting for about 3% of cardiac malformations. Atrioventricular canal occurs in two out of every 10,000 live births. Both sexes are equally affected and a striking association with Down syndrome was found. Depending on the morphology of the superior leaflet of the common atrioventricular valve, 3 types of CAVC have been delineated (type A, B and C, according to Rastelli's classification. CAVC results in a significant interatrial and interventricular systemic-to-pulmonary shunt, thus inducing right ventricular pressure and volume overload and pulmonary hypertension. It becomes symptomatic in infancy due to congestive heart failure and failure to thrive. Diagnosis of CAVC might be suspected from electrocardiographic and chest X-ray findings. Echocardiography confirms it and gives anatomical details. Over time, pulmonary hypertension becomes irreversible, thus precluding the surgical therapy. This is the reason why cardiac catheterisation is not mandatory in infants (less than 6 months but is indicated in older patients if irreversible pulmonary hypertension is suspected. Medical treatment (digitalis, diuretics, vasodilators plays a role only as a bridge toward surgery, usually performed between the 3rd and 6th month of life.

    Issues concerning the social acceptance of wind energy are major challenges for policy-makers, communities and wind developers. They also impact the legitimacy of societal decisions to pursue wind energy. Here we set out to identify and assess the factors that lead to wind energy disputes in Ontario, Canada, a region of the world that has experienced a rapid increase in the development of wind energy. Based on our expertise as a group comprising social scientists, a community representative and a wind industry advocate engaged in the Ontario wind energy situation, we explore and suggest recommendations based on four key factors: socially mediated health concerns, the distribution of financial benefits, lack of meaningful engagement and failure to treat landscape concerns seriously. Ontario's recent change from a feed-in-tariff-based renewable electricity procurement process to a competitive bid process, albeit with more attention to community engagement, will only partially address these concerns.

    2009-12-15

    A multi-stage conflict model is developed to analyze international hazardous waste disposal disputes. More specifically, the ongoing toxic waste conflicts are divided into two stages consisting of the dumping prevention and dispute resolution stages. The modeling and analyses, based on the methodology of graph model for conflict resolution (GMCR), are used in both stages in order to grasp the structure and implications of a given conflict from a strategic viewpoint. Furthermore, a specific case study is investigated for the Ivory Coast hazardous waste conflict. In addition to the stability analysis, sensitivity and attitude analyses are conducted to capture various strategic features of this type of complicated dispute.

  3. Disputable issues in the application of the Administrative Procedure Act

    Directory of Open Access Journals (Sweden)

    Dimitrijević Predrag

    2014-01-01

    Full Text Available The reform of administrative procedure and the applicable General Administrative Procedure Act (GAPA calls for determining the 'open' and 'disputable' issues in the application of this Act. The process of reforming the administrative legislation does not only imply taking into account the EU standards but also considering the complex, abundant and diverse national administrative practice and case law. The Serbian administrative practice points to some 'open' questions in the application of the current GAPA which should be the cornerstones in the reform of administrative legislation. In that course, it is crucial to start from the current administrative legislation and administrative practice. It is worth noting that the GAPA is already subject to permanent reform through the process of amending the subject-specific substantive provisions governing special administrative proceedings. Such practice should be upheld because the area of special administrative procedure is a dynamic environment where the APA is actually being modeled by amending the special administrative proceedings but in full compliance with the fundamental GAPA principles. Thus, the GAPA should be subject to minimal reform, primarily in the regulation of those procedural matters which have already passed the application test in both national and comparative practice; these 'safe points of reference' significantly improve the process in line with the basic administrative principles and largely contribute to its efficiency, as opposed to other alternative proposals on procedural solutions. The basic presumption for a successful APA reform is the functional analysis of the Draft GAPA. Some of the disputable issues include the subject matter of the GAPA, the enactment of administrative acts and concluding administrative agreements. In case of expanding the scope of the GAPA subject matter, the legislator is obliged to expressly regulate the administrative proceeding for concluding

    The research investigates the field methodologies to evaluate water losses from canals, in order to find a reliable method to identify and quantify them. This study was conducted in five canal lines in Piedmont, north-western Italy, different for hydraulic, morphological, geological and hydrogeological contexts (De Luca et alii, 2012). At a regional scale, Piedmont network consists of several tens of thousands km of irrigation canals. The loss of water due to seepage from irrigation canals constitutes a substantial part of the usable water. Irrigation canals placed in natural soil or fine and coarse sediments are characterized by water losses ranging from 20 % to more than 50 %. These losses cause economic, hydrogeological and environmental consequences: water losses evaluation from irrigation canals in the basis for the sustainable water resource use and management. First, hydrogeological and hydrological characterisation of the study area and of the bottom of the irrigation canals was carried out for every investigated canal, in order to evaluate the relationships between groundwater and stream water (eg. piezometric and hydrogeochemical survey campaigns, infiltrometry tests, penetrometric tests and electrical tomographies, soil characterizations from the bottom of investigated canals). The canals seepage rates were subsequently estimated using different methodologies: empirical formulas, inflow-outflow tests and double tracer tests. The empirical formulas applied for the study underestimated the real amount of the losses probably due to the scarce number of the considered variables. Then the canals seepage rates were evaluated employing inflow-outflow tests, considered the best tool by several authors. This method allows the determination of seepage quantities measuring inflow and outflow of a canal test reach either by instruments. The canal discharge was evaluated using a current meter. This method, even if easy to apply and practical, is not efficient

  5. Mediation as a method of solving legal disputes

    Directory of Open Access Journals (Sweden)

    Petrušić Nevena

    2004-01-01

    Full Text Available Disputes in the sphere of law are solved by applying diverse court and non-court methods and techniques. Apart from traditional methods of solving disputes by sentencing, many national legal systems have also developed different alternative mechanisms for the peaceful dispute resolution (so called ADR techniques - Alternative Dispute Resolution, among which the process of mediation has a special significance. The application of mediation exists in Serbian law as well, but this method is not being used regularly. The most important reason for this is that we still haven’t obtained all the necessary organizational, functional and other conditions that would enable a practical verification of mediation’s advantages and potentials. It is not easy to predict the pace and intensity of the future work on the enhancement and affirmation of mediation in Serbian society. However, it is evident that the time of mediation is inevitably coming.

This alternative of dispute resolution to legal proceedings in front of the law court may be considered as more favorable to the parties in conflict, from an economical perspective. Therefore the scope of the paper herein is eventually to establish that a conflict may generate value by negotiation. Further to the conclusion that by negotiation, a conflict may be solved more efficiently, the objectives of the paper are to identify (i the role played by the legal counsel in identifying the values thereto and (ii the mechanisms leading to such effect, as well as (iii the intrinsic connection between law and economics in an adequate approach of the negotiation throughout a commercial dispute. Not lastly, the paper has as objective identifying the key elements of a settlement agreement that are reflecting the added value.

    Full Text Available The authors undertake an analysis of features of mediation in individual labour disputes settlement in the Republic of Kazakhstan and the Russian Federation. The current paper also analyzes the experience of some foreign countries (USA, UK, Germany, based on a study which suggests the ways of improving the mediation institution in Kazakhstan. In addition, the identified advantages of mediation as an extra-judicial regulation of labour disputes, the authors point out the identified shortcomings of the matter in new the Labour Code of the Republic of Kazakhstan. Relevance of the topic is reasoned to the fact that in the 21st century extra-judicial settlement of disputes is preferred worldwide these days. In this context, it is no exception to the regulation of individual labour disputes without appealing to the courts. It demonstrates the role and significance of the introduction and development of conciliation procedures, including mediation, without diminishing the importance of other remedies to protect labour rights and freedoms provided in the labour legislation. An analysis of Kazakhstan’s and Russia’s procedural laws indicates a steady trend of expansion of alternative legal ways of disputes settlement in general, and particularly in labour disputes, including disputes between economic agents (employer and employee, which seems to be responded to the modern development of economic relations. Extrajudicial ways of conflict resolution may be undertaken not only by jurisdictional, but also by non-judicial mechanisms that are in the beginning stage of formation as alternative ways of resolving labour disputes at this period of Kazakhstan’s development.

    2017-12-01

    The purpose of this study was to investigate the incidence and location of the second mesiobuccal (MB2) root canal of the maxillary first molar and the relationship between the presence of an MB2 canal and the distribution of canal orifices on the pulpal floor with the aid of cone-beam computed tomographic (CBCT) technology. A total of 1008 maxillary first molars (548 patients) were randomly selected and analyzed through CBCT imaging. The association between the incidence of MB2 canals and potential impacting factors including sex, side, age, and the distribution of the main root canal orifices on the pulpal floor was explored. The interorifice distances (ie, the length of a line between the center point of any 2 orifices) at the pulpal floor level were measured using Mimics 10.01 software (ImageWorks, Materialise, Belgium). The majority of 3-rooted maxillary first molars showed 2 root canals (85.4%) in the mesiobuccal root. The incidence of MB2 canals had no statistically significant difference between the left and right sides (P > .05) but had a significant association with the patients' sex and age (P 1.26) indicated a highly probable existence of an MB2 canal. In this study, no molar presented an MB2 canal with a distance ratio of less than 1.16, whereas all molars with a ratio greater than 1.37 presented an MB2 canal without exception. A Bland-Altman scatterplot showed great agreement between the distances of the main mesiobuccal and the distobuccal canal orifices and the second mesiobuccal and the distobuccal canal orifices. Understanding the incidence of MB2 canals and the distribution pattern of canal orifices on the pulpal floor may help clinicians to quickly identify and locate MB2 canals.

    Turlock Irrigation District (TID) is located in the northern portion of the fertile San Joaquin Valley of California. TID`s primary water supply is conveyed from the 100-year-old LaGrange Diversion Dam via their historic Upper Main Canal. The original canal was constructed by excavating into slate bedrock for the uphill (cut) bank, and constructing unmortared rock walls and rock fill for the downhill (fill) embankment; the excavation was then lined with concrete. Soil fill raises of the downhill embankment over the last 30 years have reduced the slope stability to unacceptable levels in the steepest embankment areas. In March of 1994, two surficial slides prompted investigation of the long term embankment stability in the Warehouse Slide Area. Based on results of analysis for various stabilization scenarios, TID chose a stabilization method which included: (1) excavation of an access bench below the existing canal, (2) installation of steel pipe piles through the existing rock fill and into the bedrock, (3) construction of a mechanically stabilized earth (MSE) retaining wall and (4) construction of a soil-cement canal roadway pavement. The design was chosen by the owner because of cost competitiveness compared to other design alternatives and because the construction sequence allowed uninterrupted use of the canal. By using local river cobble for the MSE wall facing material, TID met the desired 50-year design life of the repair while maintaining the area`s historic visual features.

    Full Text Available En este trabajo se analizan y se estudian tres tipos de entrelazadores de bit: bloque, dorado y dorado relativo, y se determina su desempeño en un canal de línea eléctrica de baja tensión. Se utiliza el modelo de ruido dado por Middleton, para la simulación del canal de línea eléctrica de baja tensión y el algoritmo que se utiliza para generar ruido gaussiano es el método de Box-Muller. Se compara el desempeño de los entrelazadores de bits de bloque, dorado y dorado relativo, en relación al largo de la palabra versus la razón de señal a ruido y bits erróneos por palabras versus la razón de señal a ruido. La codificación de línea que se utiliza es no retorno a cero. El entrelazador de bit dorado es el que tiene el mejor desempeño, por lo tanto, se puede emplear en la transmisión por línea eléctrica de baja tensión para disminuir los errores de bits consecutivos producido por el ruido impulsivo.This paper analyzes three types of interleavers: block, golden and golden relative to determine their performance in of low voltage power line channel. The model of noise given by Middleton is used for the simulation of the low voltage power line channel and the algorithm used to generate Gaussian noise is based on the Box-Muller method. The performance of interleavers block, golden and golden relative is compared in relationship to the length of the words versus the signal to noise ratio. The error bit by word versus signal to noise ratio is compared also. The codification of line used is no return to zero. It is concluded that the interleavers of golden has the best performance, thus it can be used in data transmission in low-voltage power line, reducing errors consecutive bits produced by impulse noise.

    To assessment the angle between mandibular canal and occlusal plane at each posterior tooth region and location of mental foramen on the panoramic radiographs. This study analysed 46 half-mandibles of panoramic radiographs. Inferior border of mandibular canal was traced. Occlusal plane was drawn from lingual cusp tip of the first premolar to distolingual cusp tip of the second molar. Perpendicular line from occlusal plane was drawn at each tooth region and then tangential lines were drawn from the crossing points at canal. The angle between occlusal plane and tangential line was measured. The location of mental foramen was also studied. According to the location of mental foramen, radiographs were divided into M (mesial) group and D (distal) group on the basis of the second premolar. and then inter-group analysis about mandibular canal angle was done. The angles of mandibular canals were -17.7 .deg. C, -9.5 .deg. C, 8.2 .deg. C, 22.3 .deg. C, and 39.2 .deg. C at first premolar, second premolar, first molar, second molar, and third molar, respectively. The commonest position of the mental foramen was distal to the second premolar. Inter-group comparison showed statistically significant difference at the second premolar and the first molar (p<0.001). The acknowledgement of mandibular canal angulation and location of mental foramen can help understanding the course of mandibular canal.

    Full Text Available The Atazar Canal helps to supply Madrid with water, from the rivers Lozoya, Jarama and Sorbe. The section which operates at present starts at the Torrelaguna dam and finishes at the El Goloso reservoir. Later a further section will be added, from the Atazar dam, on the Lozoya river, to link up with the control dam at Torrelaguna. The canal capacity is 16 m3/sec, and it is 43.47 km long. It has a slope of 4/10.000. The cross section is similar to that of the Jarama canal, already built. There are interconnections between this canal and the Canal Alto, which previously supplied the high and medium part of Madrid. To overcome the ground unevenness 5 syphons have been built, the most important of which is the Colmenar Goloso syphon, which is 10.88 km in length. Construction commenced on December 10, 1962, and water reached Madrid on June 15th, 1966. The initial budget for this project was 1,500 million pesetas.El canal del Atazar refuerza considerablemente el abastecimiento de aguas a Madrid, procedentes de los ríos Lozoya, Jarama y, en un próximo futuro, del Sorbe. El tramo, actualmente en funcionamiento, empieza en el salto de Torrelaguna y finaliza en los depósitos de El Goloso. Más adelante se completará su trazado mediante un nuevo tramo que partirá del embalse de Atazar, en el Lozoya, para unirse al actual en el depósito regulador de Torrelaguna. Su capacidad es de 16 m3/s; su longitud, 43,471 km, y su pendiente, 4 diezmilésimas. La sección tipo es análoga a la del canal del Jarama, de construcción anterior. Mediante la oportuna obra de transvase se realizan intercambios entre este Canal y el Canal Alto que abastecía anteriormente la parte media y alta de la capital. Para salvar los desniveles del terreno se han construido 5 sifones, siendo el más importante el de Colmenar-Goloso, con una longitud de 10,8S4 km. El comienzo de las obras tuvo lugar el 10 de diciembre de 1962, y el agua llegó a Madrid el 15 de junio de 1966. Su

  20. Ab interno Schlemm's Canal Surgery.

    Francis, Brian A; Akil, Handan; Bert, Benjamin B

    2017-01-01

    In primary open-angle glaucoma, the site of greatest resistance to aqueous outflow is thought to be the trabecular meshwork (TM) and inner wall of Schlemm's canal. Augmentation of the conventional (trabecular) outflow pathway can facilitate physiologic outflow and subsequently lower intraocular pressure. The most recent approach to enhancing the conventional outflow pathway is via an internal approach to the TM and Schlemm's canal. Ab interno Schlemm's canal surgery includes 4 novel surgical approaches: (1) removal of the TM and inner wall of Schlemm's canal by an internal approach (ab interno trabeculectomy), (2) implantation of a microstent to bypass the TM, (3) disruption of the TM and inner wall of Schlemm's canal via an internal approach (ab interno trabeculotomy), and (4) dilation of Schlemm's canal via an internal approach (ab interno canaloplasty). The first category includes the Trabectome (Neomedix, Tustin, CA, USA), and Kahook Dual Blade (New World Medical, Rancho Cucamonga, CA, USA). The second category includes the iStent (Glaukos, Laguna Hills, CA, USA), as well as the investigational Hydrus Microstent implant (Ivantis, Irvine, CA, USA). The third category includes gonioscopic-assisted transluminal trabeculotomy (iSciences catheter; Ellex, Adelaide, Australia), and 360° suture trabeculotomy (TRAB360, Sight Sciences, Menlo Park, CA, USA). The fourth category includes ab interno canaloplasty or AbiC (Ellex), and Visco360 (Sight Sciences). In contrast to external filtration surgeries, such as trabeculectomy and aqueous tube shunt, these procedures are categorized as internal filtration surgeries and are performed from an internal approach via gonioscopic guidance. Published results suggest that these surgical procedures are both safe and efficacious for the treatment of open-angle glaucoma. © 2017 S. Karger AG, Basel.

    2014-11-01

    Variation in semicircular canal morphology correlates with locomotor agility among species of mammals. An experimental evolutionary mouse model was used to test the hypotheses that semicircular canal morphology (1) evolves in response to selective breeding for increased locomotor activity, (2) exhibits phenotypic plasticity in response to early-onset chronic exercise, and (3) is unique in individuals possessing the minimuscle phenotype. We examined responses in canal morphology to prolonged wheel access and selection in laboratory mice from four replicate lines bred for high voluntary wheel-running (HR) and four nonselected control (C) lines. Linear measurements and a suite of 3D landmarks were obtained from 3D reconstructions of μCT-scanned mouse crania (μCT is microcomputed tomography). Body mass was smaller in HR than C mice and was a significant predictor of both radius of curvature and 3D canal shape. Controlling for body mass, radius of curvature did not differ statistically between HR and C mice, but semicircular canal shape did. Neither chronic wheel access nor minimuscle affected radius of curvature or canal shape These findings suggest that semicircular canal morphology is responsive to evolutionary changes in locomotor behavior, but the pattern of response is potentially different in small- versus large-bodied species. © 2014 The Author(s).

    The hypothesis that somatotype and cervical spine developmental canal stenosis may be associated has been investigated by anthropometry and measurement of lateral projection cervical spine radiographs. A significant association of canal size with somatotype has been found such that those with developmentally narrow canals are more likely to have relatively shorter long-bones, particularly in the upper arm, and longer trunks.

    The choice of single- versus multiple-visit root canal treatment for infected teeth is in dispute. The purpose of this systematic review was to compare the healing rate and post-obturation pain of single- versus multiple-visit root canal treatment for teeth with infected root canals. An exhaustive literature search combined with specified inclusion criteria was performed to identify randomized or quasi-randomized controlled trials (RCTs or quasi-RCTs), comparing root canal treatment in single and multiple appointments (2 or more visits) in patients with infected root canals. Ten RCTs were identified and included in this review. Of these, 6 compared the healing rate and 5 compared the prevalence of post-obturation pain in single- and multiple-visit root canal treatment on teeth with infected root canals. No significant difference was observed in the healing rate between single- versus multiple-visit root canal treatment, as well as the incidence of medium-term post-obturation pain. As to the short-term follow up, the prevalence of post-obturation pain was significantly lower in single-visit than in multiple-visit group. On the basis of current studies, the healing rate of single- and multiple-visit root canal treatment is similar for infected teeth. Patients experience less frequency of short-term post-obturation pain after single-visit than those having multiple-visit root canal treatment. Copyright © 2011 American Association of Endodontists.

    2012-09-15

    This study evaluated the association between cone beam computed tomography (CBCT) and panoramic radiographs in the assessment of a superimposed relationship between the mandibular canal and impacted third molars. The study samples consisted of 175 impacted third molars from 131 patients who showed a superimposed relationship between the mandibular canal and third molars on panoramic radiographs and were referred for the examination of the mandibular canal with CBCT. Panoramic images were evaluated for the darkening of the root and the interruption of the mandibular canal wall. CBCT images were used to assess the buccolingual position of the mandibular canal relative to the third molar, the proximity of the roots to the canal, and lingual cortical bone loss. The association of the panoramic and CBCT findings was examined using a Chi-square test and Fisher's exact test. Panoramic radiographic signs were statistically associated with CBCT findings (P<0.01). In cases of darkening roots, lingual cortical bone loss or buccally positioned canals were more frequent. In cases in which the mandibular canal wall was interrupted on panoramic radiographs, contact or lingually positioned canals were more frequent. The results of this study suggest that contact between the mandibular third molar and canal and a lingually positioned canal could be more frequently observed in cases of the interruption of the white line of the mandibular canal and that there could be more lingual cortical loss in cases of darkening roots.

    2011-10-01

    Full Text Available In recent years, there were increasing interests in quantitative survey research on experiences of legal problems and access to justice in an unprecedented number of countries. Such survey research was initially conducted in the U.K. and the U.S. and later in Canada, New Zealand and Australia, countries with the Anglo-American legal tradition. However, a similar survey was recently carried out in the Netherlands, Japan and Hong Kong, countries of the Civil Law tradition, some of them with Asian social background. Now we have fantastic opportunities for comparative studies of civil disputes and dispute handling behavior among countries with different socio-legal backgrounds. Drawing upon these survey data, we discussed on how experiences of legal problems and occurrences of disputes differ among countries, how legal machineries are used or not used to resolve disputes, how levels of satisfaction with outcomes differ, and research designs and quantitative analytical methods for future surveys.DOWNLOAD THIS PAPER FROM SSRN: http://ssrn.com/abstract=1941689

  1. The mutual agreement procedure and arbitration of double taxation disputes

    Directory of Open Access Journals (Sweden)

    Ilias Bantekas

    2008-12-01

    Full Text Available It is in the interest of most states to eliminate double taxation (i.e. the payment of the same tax in two jurisdictions oftransnational commercial enterprises. Because such disputes involve, on the one hand, the state imposition of taxes, a right universally asserted by all states, and private entities on the other, taxation disputes between such parties are not, on their face, easily susceptible to arbitration. This article analyzes two disputesettlement procedures-the OECD First Model Tax Convention and a similar EU Convention-with the exclusive focus on disputes relatingto the imposition of double taxation. It will look at the ways in which state roles may vary under these procedures from assisting inthe negotiation process to taking a part similar to, but with important differences from, diplomatic protection on behalf of an affected enterprise. The article will examine the situations under which the settlement procedure is required and/or available, how the procedures are triggered, the obligations and parts played bythe parties, the means by which the disputes are resolved (from negotiations to tribunals and the limitations of the procedures. Are they “taxpayer friendly”? As a result the reader may draw comparisons between the two procedures. Finally, the article will look at the proposed OECD Arbitration Clause which is intended to be incorporated into Article 25 of the OECD Model Tax Convention as well as how thesemechanisms relate and/or conflict with bilateral tax treaties and theGATS.

    negotiations of the two parties, related to determination of the frontier. The records were disclosing consent of the parties on some sections of the disputed frontier that has not reached the form of an international treaty binding to the parties. The Chamber used to confirm such consent of the parties as their acceptance of mutual frontier and, in such occasions, it did not investigate title deeds related to these sectors. The Chamber investigated evidences, submitted by the parties, on exercise of their powers in dispute areas. It was done to explore whether effective exercise of power of one or other party required a correction of uti possidetis frontier. There was no case where the Chamber found that principle of effectivités asked the correction uti possideties frontier. The Chamber took into account, also, topography and by an occasion it changed a little bit uti possidetis frontier to provide topographically superior boundary line. Also, it applied the customary rule that the frontier follows the middle of the bed of a non-navigable river. In such a way, the Chamber resolved the dispute by application of uti possidetsi juris principle as the basic principle which was supplemented or substituted by other rules of international law.

  19. Arbitrating a fiction: Canadian federalism and the Nova Scotia/Newfoundland and Labrador boundary dispute

    2003-09-30

    The dispute between the provinces of Nova Scotia and Newfoundland and Labrador, regarding ownership of natural resources to be found in the offshore area lying between the two provinces is discussed. Constitutionally, ownership of offshore natural resources belongs to the federal government. In this instance, the intention was to share control over development and revenues with the provinces through joint management accords, however, a dispute over offshore boundary arose, which eventually resulted in an arbitration tribunal. This paper analyzes the terms of reference for the tribunal and its findings, and concludes that the tribunal process was flawed. The authors cast doubts on the appropriateness of the tribunal's role, the method by which it reached its decision, and the legality of its findings. They conclude that the tribunal merely cloaks a political decision in legal garb since there are no genuine boundaries between the provinces, and the tribunal process simply apportioned federal resources between two provinces. The authors ultimately conclude that by resorting to the tribunal process the federal minister of natural resources was able to avoid political responsibility for making an unpopular decision by relying on a pseudo-judicial body for technical recommendations, and in so doing undermined the legitimacy of the Canadian federal system by obscuring the already murky lines of accountability of the federal and provincial governments. 57 end notes.

  20. Justice Dispensation through the Alternative Dispute Resolution System in India

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available The Law Commission of India in its 222nd report emphasized the need for Alternative Disputes Resolution (ADR for the dispensation of justice, because the courts are inaccessible owing to various factors, e.g., poverty, social and political backwardness, illiteracy, ignorance, procedural formalities and inordinate delay in judgments. During the ancient period the disputes were resolved in an informal manner by neutral third persons or people’s court in villages and it continued till the middle of the 20th century. Unfortunately, after the Independence of India in 1947, this system was dissuaded and the government permitted to continue the adversarial system of justice. In 1980, a committee was set up. It recommended Lok Adalats (People’s Courts. In 1987, the Legal Services Authorities Act was enacted. This Act obligates the states to provide free legal aid to poor persons. Besides this, the Act provides for the establishment of permanent Lok Adalats.This is one of the important modes of ADR. Lok Adalats have been established in all the districts of the country. They bring conciliatory settlement in complicated cases arising out of matrimonial, landlord-tenants, property, insurance and commercial disputes. There are four methods of ADR, viz., negotiation, mediation, conciliation and arbitration. Mediation and arbitration are widely preferred. They are alternatives to litigation. The Arbitration Act for the first time was enacted in 1889 and it was subsequently amended many times. On the objections raised by the Supreme Court of India and also on the adoption of UNCITRAL Model Law on International Commercial Arbitration, in 1996 Arbitration and Conciliation Act was enacted. This law is almost the same as is almost in all the countries.Further, the Government of India established International Centre for Alternative Disputes Resolution (CADR with the objectives of promotion, propagation, and popularizing the settlement of domestic and

  1. Exploring risk judgments in a trade dispute using Bayesian networks.

    2014-06-01

    Bayesian networks (BNs) are graphical modeling tools that are generally recommended for exploring what-if scenarios, visualizing systems and problems, and for communication between stakeholders during decision making. In this article, we investigate their potential for exploring different perspectives in trade disputes. To do so, we draw on a specific case study that was arbitrated by the World Trade Organization (WTO): the Australia-New Zealand apples dispute. The dispute centered on disagreement about judgments contained within Australia's 2006 import risk analysis (IRA). We built a range of BNs of increasing complexity that modeled various approaches to undertaking IRAs, from the basic qualitative and semi-quantitative risk analyses routinely performed in government agencies, to the more complex quantitative simulation undertaken by Australia in the apples dispute. We found the BNs useful for exploring disagreements under uncertainty because they are probabilistic and transparently represent steps in the analysis. Different scenarios and evidence can easily be entered. Specifically, we explore the sensitivity of the risk output to different judgments (particularly volume of trade). Thus, we explore how BNs could usefully aid WTO dispute settlement. We conclude that BNs are preferable to basic qualitative and semi-quantitative risk analyses because they offer an accessible interface and are mathematically sound. However, most current BN modeling tools are limited compared with complex simulations, as was used in the 2006 apples IRA. Although complex simulations may be more accurate, they are a black box for stakeholders. BNs have the potential to be a transparent aid to complex decision making, but they are currently computationally limited. Recent technological software developments are promising. © 2014 Society for Risk Analysis.

  2. The mutual agreement procedure and arbitration of double taxation disputes

    Directory of Open Access Journals (Sweden)

    Ilias Bantekas

    2008-10-01

    Full Text Available It is in the interest of most states to eliminate double taxation (i.e. the payment of the same tax in two jurisdictions of transnational commercial enterprises. Because such disputes involve, on the one hand, the state imposition of taxes, a right universally asserted by all states, and private entities on the other, taxation disputes between such parties are not, on their face, easily susceptible to arbitration. This article analyzes two dispute settlement procedures-the OECD First Model Tax Convention and a similar EU Convention-with the exclusive focus on disputes relating to the imposition of double taxation. It will look at the ways in which state roles may vary under these procedures from assisting in the negotiation process to taking a part similar to, but with important differences from, diplomatic protection on behalf of an affected enterprise. The article will examine the situations under which the settlement procedure is required and/or available, how the procedures are triggered, the obligations and parts played by the parties, the means by which the disputes are resolved (from negotiations to tribunals and the limitations of the procedures. Are they “taxpayer friendly”? As a result the reader may draw comparisons between the two procedures. Finally, the article will look at the proposed OECD Arbitration Clause which is intended to be incorporated into Article 25 of the OECD Model Tax Convention as well as how these mechanisms relate and/or conflict with bilateral tax treaties and the GATS.

    Full Text Available The focus of the present study was to examine the effect of canal bank filtration on the quality of water and the geological settings along the banks of canals at the shallow depth aquifers. The four Model wells were drilled at different locations of the Line channel, Pinyari and phulali canals in the study area. The samples of soil were collected throughout drilling of the model wells for the analysis of grain size distribution .In addition to this, canal water and model well water samples were collected and analyzed for the water quality characteristics during winter and summer seasons. The analysis of soil and water samples reveals that the ground water is influenced by the grain size distribution, hydraulic conductivity and the location of the model Wells. The model well that has higher percentage of 0.075 mm of grain size distribution(hydraulic conductivity between 10-25 ft/day was more suitable for the filtration of the canal water through its banks, followed by 0.15 mm of grain size distribution (hydraulic conductivity > 25ft/ day. Moreover, the present study also shows that the canal water filtration is suitable in terms of total alkalinity, nitrate-nitrogen, total iron and pH to get the potable water at the location near upstream of the canal, especially in the summer season.

    To isolate and characterize bacteria and fungi from the healthy ear and to obtain susceptibility profiles on each bacterial isolate. Prospective. Specimens were collected from the external canals and cerumen of healthy subjects. Species-level identification was obtained by combining phenotypic and genotypic data. End-point minimal inhibitory concentration testing was performed using National Committee for Clinical Laboratory Standards recommended methods. One hundred sixty-four subjects were cultured. Seventeen canal and 16 cerumen specimens showed no growth. One hundred forty-eight cerumen specimens yielded 314 organisms, including 23 fungi. One hundred forty-seven canal specimens yielded 310 organisms, including 7 fungi. Of 291 bacteria isolated from cerumen, 99% were Gram-positive. Of 302 bacteria isolated from the canal, 96% were Gram-positive. Staphylococci were 63% of both the cerumen bacteria and the canal bacteria. Coryneforms represented 22% of the bacteria in cerumen and 19% in the canal. Turicellaotitidis was the primary coryneform isolated from both the canal and the cerumen. Streptococci-like bacteria were 10% from the cerumen, 7% from the canal. In both cerumen and canal, Alloiococcusotitis was more than 95% of the streptococci-like bacteria. Fifteen gram-negative organisms were isolated from the canal and cerumen, including four Pseudomonas aeruginosa strains. The percentages of Staphylococcus epidermidis isolates that had high-level resistance (> or =8 microg/mL) were as follows: to neomycin, 28% from cerumen and 11% from the canal; to oxacillin, 28% from cerumen and 25% from the canal; and to ofloxacin, 15% from cerumen and 19% from the canal. Turcellaotitidis and A. otitidis were present with a much higher frequency than previously described, lending evidence that they be considered normal otic flora. Corynebacterium auris, previously reported only in children, was isolated from normal adults.

    1980-01-01

    In 1968, a canal draining cooling water from a factory was found to be the source of infection with primary amoebic meningoencephalitis (PAME) (one case). The bed of the canal lined with stone slabs was about 2 m wide, the flow rate of water was approximately 2 m/sec. Average annual water temperatures ranged from 27-30 degrees C. In culture, Naegleria fowleri was not found in the water of the canal, but it was present in scrapings off the canal walls and in its bottom sediment for a length of about 2 km starting at the site of the outlet of the water from the factory. The maximum number of amoebae in 1 liter of the sample was 800 individuals. The present paper discusses the detective efficacy of the culture methods employed, and the epidemiological bearing of the findings.

    To determine the more valuable information to detect the mandibular canal and the mental foramen in panoramic radiographs of a selected Korean population for the implant. This study analysed 288 panoramic radiographic images of patients taken at the Dental hospital of Chosun University retrospectively. Indirect digital panoramic X-ray machine (ProlineXC, PLANMECA, Finland) with processing by using Directview CR950 (Kodak, U.S.A.) and Direct digital panoramic X-ray machine (Promax, PLANMECA, Finland) were used for all exposures. All images were converted into Dicom format. The common position of the mental foramen was in line with the longitudinal axis of the second premolar (68.1%). The mental foramen was lower symmetrical in 81.8% of cases. The mandibular canal was not identified at anterior portion and discontinued with the mental foramen in 27.8% of all cases, in 42.4% identified with lower border line continued with the mental foramen, in 14.6% with both upper and lower border lines, and in 15.3% unilaterally identified with lower border line. Clinicians can estimate the upper border line of the mandibular canal from the confirmation of the mental foramen and the lower border line of the mandibular canal symmetrically on the panoramic radiography taken in adjusted midsaggital plane of patient's head.

    The hypothesis that somatotype and cervical spine developmental canal stenosis may be associated has been investigated by anthropometry and measurement of lateral projection cervical spine radiographs. A significant association of canal size with somatotype has been found such that those with developmentally narrow canals are more likely to have relatively shorter long-bones, particularly in the upper arm, and longer trunks.

    Resent advances have led to the reexamination of the intraosseous pathway of the chorda tympani a few years ago and they stated that the nerve never enters the mandibular fossa and its exit the skull base in the sphenopetrosal fissure. In our report, 58 temporal bones were investigated after maceration and formalin fixation in order to understand the development of the anterior chordal canal. Our study revealed that the chorda tympani leaves the tympanic cavity through the tympanosquamosal fissure before formation of the anterior chordal canal of Huguier. This canal is situated parallel to and in front of the musculotubal canal and formed by the processus inferior tegminis tympani and the sphenoid bone between the second and fifth years of age. Prior to the age of 2, only the exit of the bony canal exists which is gradually followed by the appearance of a groove in the growing processus inferior tegminis tympani. The borders of the groove elevate and develop to upper and lower plates which lengthen with similar plates of the sphenoid bone, completing the anterior chordal canal by the fifth postnatal year. The entrance of the canal develops above the petrotympanic fissure and similar to the canal itself, it is also completely formed in the fifth year. In case of an incomplete development the anterior chordal canal remains partially opened laterally which might allow the head of the mandibula to effect the chorda tympani mechanically causing Costen's syndrome.

    Similar to many types of legal institutions, international courts employ a wide variety of legitimation strategies in order to establish and maintain a sound basis of support among their constituents. Existing studies on the legitimacy or legitimating efforts of the World Trade Organization's (WTO......) judicial bodies have relied largely on theoretical or normative priors about what makes these institutions legitimate. In contrast, this paper directly connects the study of courts' legitimating efforts with their effects by empirically mapping how the WTO Dispute Settlement Mechanism's (DSM) exercise...... of authority has been received by the system's primary constituents—WTO Members. Drawing on an original dataset of statements made by WTO Members within meetings of the Dispute Settlement Body from 1995-2013 and a series of interviews, this paper provides a descriptive analysis of expressed views on its...

    Lloyd-Smith, Mariann E; Bell, Lee

    2003-01-01

    The paper examines the rise of environmental justice issues in Australia, evident in two toxic disputes; the first, in a Perth outer suburb in Western Australia where residents faced both a hazardous waste dump and the nation's biggest chemical fire; and the second, in the Sydney suburb of Botany where residents were confronted with the destruction of what is thought to be, the world's largest stockpile of hazardous hexachlorobenzene (HCB) waste. The paper reviews the range of factors that impacted the local communities' fight for environmental justice. It explores the limitations of risk assessment and risk-based policies, as well as the problematic role of the expert and the communication of risk. The informational inequity and resource disparities so evident in toxic disputes are highlighted. The case studies confirmed the inequitable distribution of chemical risk as a failure to secure environmental justice for all Australians.

    Full Text Available Actuality. The topic of teaching economic disciplines has always been relevant and useful. The article considers the technique of organization and of the seminar-dispute on economic subjects. In this paper there are also identified criteria for evaluating the participants of the seminar-dispute. Methods of teaching economic disciplines in higher education are held by holding lectures and seminars. The seminar provides an opportunity to determine the degree of independence and responsibility, to rise creativity in every student. The purpose is to disclose the main objectives of the seminar-dispute, which as a result of the preliminary work on the program material, the teacher and students are in a situation of direct active communication during performance of students on topics arising between discussion and generalizations by teacher, bu solving the problem of cognitive, developmental and educational character that imparted methodological and practical skills to students. Methods. Logical and descriptive, monographic, analysis and synthesis. Results. It should be concluded that in preparation for the seminar, students acquire the skills to work with the book, read the analysis, selection of the main and necessary speeches for the report, , and systematizing the selected materials. Students learn to clearly express their thoughts, work out the ability to speak without papers to prove their beliefs, to establish contact with the audience, etc. Accordingly, it is best to choose the topics of the seminar where the student must not only learn certain information, but also find a solution. One of the most popular forms of classes in the framework of methodological approaches to the teaching of economic disciplines is a seminar-dispute.

    2013-09-01

    Full Text Available Within the framework of a sociocultural theory of human development and learning (Vigotsky, 2009; Bruner, 1986; Nelson, 1996; Tomasello, 1998, 2003, this paper aims to investigate the multimodal construction of arguments produced by 5 year-old children during disputes in a kindergarten play situation. We considered the juxtaposition of information provided by resources from different semiotic fields (Goodwin, 2000, 2007. The corpus consists of the interactions in a group of children while they play with building blocks. This play situation was videotaped in a kindergarten classroom that is attended by an urban marginalized population of outer Buenos Aires, Argentina. The analysis makes use of the qualitative logic derived from the methodological tools of Conversation Analysis developed in previous research (Goodwin, 2000, 2007; Goodwin and Goodwin, 1990, 2000; Goodwin, Goodwin and Yaeger-Dror, 2002. The results show the different semiotic fields that overlap with the linguistic expression of the arguments or points of view that children maintain while quarrelling during play situations. This demonstrates the importance of attending to intonation, the use of space, the direction of gaze, gestures, and body positioning as they are components that contribute to the argumentative force of the utterances in disputes. These elements emerge as indicators of the emotions that parties experience in disputes which can not be disregarded when attempting to account for how argumentation occurs in real situations of interaction.

    2014-07-01

    Full Text Available Mediation provides a means of resolving disputes that promises to reduce litigation while avoiding further damage to party relationships. The present study addressed the question whether parents engaged in parenting disputes generated by divorce or separation received the promised benefits of mediation when services were delivered by means of community mediation, which combined the dual features of free services and volunteer mediators. Reported outcomes such as agreements, party satisfaction, relationship changes, and court involvement, as well as the connection between these outcomes and party factors of custodial status and income level, were examined, and several encouraging trends emerged. Results indicated that an economically diverse group of disputing parents were provided access to mediation services delivered under community mediation. Moreover, the prospect of avoiding litigation motivated a majority of parents to participate in community mediation. The positive outcomes reported by most parents, irrespective of income level and custodial status, included agreement and process satisfaction rates consistent with national trends, the development of parenting plans, and for a sizable minority of parents, reduced court involvement and improved between-parent interactions. However, non-custodial parents tended to be significantly more positive about mediation’s helpfulness with parenting issues than were custodial parents.

    Full Text Available On 11 June 2013, the Commission issued the Recommendation on common principles for injunctive and compensatory collective redress mechanisms in the Member States concerning the violations of rights granted under Union law. The main areas where private enforcement of rights granted under Union law in the form of collective redress is of value are consumer protection, competition, environment protection, protection of personal data, financial services legislation and protection of investments. Point 13 of the Recommendation concurrently emphasises that the principles it puts forward relate both to judicial and out-of-court collective redress. The Member States should ensure that judicial collective redress mechanisms are accompanied by appropriate means of collective alternative dispute resolution available to the parties before and throughout the litigation.

    Full Text Available Background: Preparation of root canal is an important stage in endodontic treatment. During conducting preparation, it is always be followed with root canal irrigation that has aim to clean root canal from necrotic tissue remains, grind down dentin powder, micro organism, wet the root canal to make preparation process of root canal easier, and solute root canal content at area that can not be reached by equipment. Flesh of Tamarindus indica (pulpa tamarindorum is used as traditional medicine and it contains vitamin C (antioxidant, protein, fat, glucose, etc. Previous research shows that 5% tamarindus indica extract can clean smear layer but it is more cytotoxicity to cell line BHK–21 than sterilized aquabides. Purpose: This research is to compare cytotoxicity between 5% Tamarindus indica extract with 3% H2O2 as root canal irrigation material. Method: Four teen culture cell line BHK 21 divides into 2 groups. Group 1 is treated with 3% H2O2 and Group 2 is treated with 5% Tamarindus indica extract, for about 2.5 minutes in every group. Then, living and death cell percentage is measured. Data is analyzed with independent t test with significant level of 0.05%. Result: The research showed that death cell in group 1 was 29.3% and in group 2 was 21.1%. There was a significant different (p < 0.05 between group 1 and group 2. Conclusion: Cytotoxicity of 5% Tamarindus indica extract to the cell line BHK–21 is lower than 3% H2O2.

  7. CONTEXTUALIZING THE USE OF THE DIPLOMATIC ALTERNATIVE IN CONFLICT RESOLUTION IN THE DISPUTE BETWEEN NIGERIA AND CAMEROON OVER BAKASSI 1994 -2006

    Ekpotuatin Charles Ariye

    2017-09-01

    Full Text Available This study focuses on the subject of the application of alternative means as a complement to the judicial, adjudication and arbitration options in the resolution of disputes/conflicts. The Nigeria-Cameroon conflict over Bakassi is used as a case in point. By blending the theoretical perspectives on the diplomacy/negotiation approach with the reality of this case it argues that the application of alternative dispute resolution mechanism, in this instance, facilitated a long lasting and negotiated settlement, which led to amicable and final resolution. With the understanding that dispute/conflict resolution seeks to find solutions acceptable to both parties to achieve peaceful coexistence, the question arises as to whether the ICJ’s ruling in itself was able to amicably resolve the dispute? What we find is that the Ruling of 2002 did not in itself lead to instant settlement, rather it drew negative responses from Nigeria, so that it took the intervention of stakeholders in the international system, especially the Western countries, and particularly the UN and its then Secretary-General, Kofi Annan, to activate the UN machinery to put in place direct bilateral talks between Nigeria and Cameroon to iron out their differences. The emergent Mixed Commission and the Greentree Agreement of 2006 ensured the achievement of reconciliation, lasting peace and final resolution along the lines of the ICJ’s Judgment of 2002.

  10. The enigma of the lateral canal.

    Weine, F S

    1984-10-01

    It is difficult to summarize an article of this type, in which the author is certain that his case has been presented fairly, but is aware that other views that are contrary could be stated and endorsed by pertinent clinical cases. Bearing this fact in mind, I wish to reiterate the following: Lateral canals are demonstrated in endodontic cases with much less frequency than they exist. This variance rarely, if ever, causes an endodontic failure. Some demonstrated lateral canals may really be other conditions. Preoperative evaluation should include examination of radiographs for lateral, as well as periapical, lesions. Lateral canals may be demonstrated by a variety of filling techniques. Careful canal preparation may enhance the frequency of such demonstration. Cases with necrotic pulps probably yield more frequent demonstration than do cases with vital pulps. Lateral canals harboring inflamed and/or infected material may cause pain during endodontic treatment. They may simulate periodontal disease and may cause problems with treatment if present when a tooth is left open for drainage. Periodontal disease may cause pulp exposure via lateral canals located coronally. Improper use of post room may lead to lateral failure from breakdown of tissue in a lateral canal. The enigma of the lateral canal has been the object of description and discussion in many articles, but no one is truly certain of their exact significance in endodontic therapy for the long haul.

    2015-08-01

    The purpose of this study was to assess computed tomography (CT) findings of mandibular nutrient canals using CT images. We retrospectively analyzed the mandibular CT images of 194 consecutive patients. For image analysis such as canal prevalence, location, number, size, shape, and the CT value of nutrient foramina were determined using CT axial images of 0.5 and 3 mm slice thickness. We revealed that the nutrient canals were seen 94.3% in the mandible, mostly seen in the anterior region. By location, nutrient canals were particularly seen between the central and lateral incisors. The mean number of nutrient canals was 2.7. The mean diameter of the nutrient foramen between the central and lateral incisors was 1.0 mm. In about 80% of the cases, foramina between the central and lateral incisors were ovoid. The mean CT value for the nutrient foramina between the central and lateral incisors was 411 HU. Mandibular nutrient canals were ovoid shape, and the mean CT value was 411 HU. By preoperative knowledge of the position and anatomy of the mandibular nutrient canals, complications such as injury to the nutrient canals can be avoided.

  12. Type III apical transportation of root canal

    Directory of Open Access Journals (Sweden)

    Shiv P Mantri

    2012-01-01

    Full Text Available Procedural accidents leading to complications such as canal transportation have been ascribed to inapt cleaning and shaping concepts. Canal transportation is an undesirable deviation from the natural canal path. Herewith a case of apical transportation of root canal resulting in endodontic retreatment failure and its management is presented. A healthy 21-year-old young male presented discomfort and swelling associated with painful endodontically retreated maxillary incisor. Radiograph revealed periradicular radiolucency involving underfilled 11 and overfilled 12. Insufficiently obturated 11 exhibited apical transportation of canal. This type III transportation was treated by periradicular surgery and repair using white mineral trioxide aggregate (MTA. Comfortable asymptomatic patient presented uneventful healing at third and fourth month recall visits. A decrease in the size of radiolucency in radiograph supported the clinical finding. In the present case, MTA is useful in repairing the transportation defect. The result of these procedures is predictable and successful.

  13. Updated regime equations for alluvial Egyptian canals

    Directory of Open Access Journals (Sweden)

    Fahmy Salah Abdelhaleem

    2016-03-01

    Full Text Available Real accuracy of several regime relationships for designing stable alluvial channels in Egypt was determined. Extensive field measurements had been carried out on 26 Egyptian stable canals, which cover various categories of irrigation canals starting from distributary, branch to carrier canals in Egypt. Analysis of 1484 velocity profiles for 371 cross sections was employed in order to formulate new regime equations characterizing Egyptian canals. The functional formulations to include the flow depth, cross section area, hydraulic radius and mean velocity were achieved. This research compared the deduced formulas from the measured data with the equations derived by other researchers for stable channel design. It was found that the derived formulas are reliable and could help in the design of Egyptian canals to convey a discharge ranging from 0.11 to 287.5 m3/s (0.0095–24.84 millions m3/day.

    Over the past 20 years the East China Sea territorial and maritime dispute has become a key flashpoint in East Asia. Although the dispute has caused diplomatic and economic damage, its existence suits the key actors involved, thus reducing the incentive for resolution. The dispute undergirds...... the Chinese Communist Party's nationalist credentials and thus its legitimacy.

    1979-12-01

    This study assesses the potential of mediation as a tool for resolving disputes related to the environmental regulation of new energy facilities and identifies possible roles the Federal government might play in promoting the use of mediation. These disputes result when parties challenge an energy project on the basis of its potential environmental impacts. The paper reviews the basic theory of mediation, evaluates specific applications of mediation to recent environmental disputes, discusses the views of environmental public-interest groups towards mediation, and identifies types of energy facility-related disputes where mediation could have a significant impact. Finally, potential avenues for the Federal government to encourage use of this tool are identified.

  1. The fluoridation war: a scientific dispute or a religious argument?

    Science.gov (United States)

    Newbrun, E

    1996-01-01

    Communal water fluoridation is not considered controversial by the vast majority of the scientific community; however, politically it has persisted as an issue that many legislators and community leaders have avoided because of an aura of dispute, it has been a battleground for vigorous opposition by a very small but outspoken minority who have fought it with the dedication of religious zealots. This paper reviews the nature of the opposition, who they are, the broad thrust of their arguments, some of the specific issues they have raised, and their techniques.

  2. Wave Mechanics of the Vestibular Semicircular Canals.

    Science.gov (United States)

    Iversen, Marta M; Rabbitt, Richard D

    2017-09-05

    The semicircular canals are biomechanical sensors responsible for detecting and encoding angular motion of the head in 3D space. Canal afferent neurons provide essential inputs to neural circuits responsible for representation of self-position/orientation in space, and to compensatory circuits including the vestibulo-ocular and vestibulo-collic reflex arcs. In this work we derive, to our knowledge, a new 1D mathematical model quantifying canal biomechanics based on the morphology, dynamics of the inner ear fluids, and membranous labyrinth deformability. The model takes the form of a dispersive wave equation and predicts canal responses to angular motion, sound, and mechanical stimulation. Numerical simulations were carried out for the morphology of the human lateral canal using known physical properties of the endolymph and perilymph in three diverse conditions: surgical plugging, rotation, and mechanical indentation. The model reproduces frequency-dependent attenuation and phase shift in cases of canal plugging. During rotation, duct deformability extends the frequency bandwidth and enhances the high frequency gain. Mechanical indentation of the membranous duct at high frequencies evokes traveling waves that move away from the location of indentation and at low frequencies compels endolymph displacement along the canal. These results demonstrate the importance of the conformal perilymph-filled bony labyrinth to pressure changes and to high frequency sound and vibration. Published by Elsevier Inc.

    Nica, Luminita; Todea, Carmen; Furtos, Gabriel; Baldea, Bogdan

    2014-01-01

    Bonding to root canal dentin may be difficult due to various factors: the structural characteristic of the root canal dentin, which is different from that of the coronal dentin; the presence of the organic tissue of the dental pulp inside the root canal, which has to be removed during the cleaning-shaping of the root canal system; the smear-layer resulted after mechanical instrumentation, which may interfere with the adhesion of the filling materials; the type of the irrigants used in the cleaning protocol; the type of the sealer and core material used in the obturation of the endodontic space; the type of the materials used for the restoration of the endodontically treated teeth. The influence of the cleaning protocol, of the root canal filling material, of the type of the adhesive system used in the restoration of the treated teeth and of the region of the root canal, on the adhesion of several filling and restorative materials to root canal dentin was evaluated in the push-out bond strength test on 1-mm thick slices of endodontically treated human teeth. The results showed that all these factors have a statistically significant influence on the push-out bond strength. Formation of resin tags between radicular dentin and the investigated materials was observed in some of the samples at SEM analysis.

    The Agua Salud Project utilizes the Panama Canal’s (Canal) central role in world commerce to focus global attention on the ecosystem services provided by tropical forests. The Canal was one of the great engineering projects in the world. Completed in 1914, after almost a decade of concerted effort, its 80 km length greatly shortened the voyage between the Atlantic and Pacific Oceans. An entire class of ships, the Panamax, has been constructed to maximize the amount of cargo that can be carried in a Canal passage. In today’s parlance, the Canal is a “green” operation, powered largely by water (Table 1). The locks, three pairs on each end with a net lift of 27 meters, are gravity fed. For each ton of cargo that is transferred from ocean to ocean, about 13 tons of water (m3) are used. Lake Gatún forms much of the waterway in the Canal transect. Hydroelectricity is generated at the Gatún dam, whenever there is surplus water, and at Madden Dam (completed in 1936) when water is transferred from Lake Alhajuela to Lake Gatún. The Canal watershed is the source of drinking water for Panama City and Colon City, at either end of the Canal, and numerous towns in between.

    Full Text Available Enlargement of the mandibular canal is a rare radiological finding. Clinically, it may or may not be associated with sensory deficits. We report four cases of widening of the mandibular canal observed with various methods of imaging with different clinical characteristics. We describe this unique radiological finding and elaborate the importance of quality assessment of the imaging that is vital for accurate diagnosis and treatment planning. Clinicians should be mindful when assessing the imaging whenever the size of the mandibular canal is implicated. The case ranged from a benign tumor to malignancy, radiological errors, and artifacts. A more superior imaging or treatment modality was necessary to ascertain the diagnosis.

    Full Text Available This Article represents an overview of long-running border dispute between two neighboring states – Republic of Croatia and Republic of Slovenia in the maritime area of the Northern Adriatic. Despite more than two decades of unsuccessful efforts, including several documents controversial on one or both sides, there are still some disputable points waiting for the final settlement. It is expected to be reached by the Arbitration Tribunal established by the Arbitration Agreement between Croatia and Slovenia, signed in 2009. Without any doubt, this Agreement represents a step forward in their mutual efforts toward peaceful solution, but also contains few open questions to be resolved by the Arbitration Tribunal. In this Article the author presents brief overview of long-time efforts that led to the conclusion of the Arbitration Agreement, as well as the main components that has to be considered – strong political demands in relation to preserve territorial integrities of both states and – at the end – to accomplish a peaceful solution in accordance to the rules of international law.

  8. Postponement of execution of the administrative act in administrative dispute

    2012-01-01

    Full Text Available The newly established legal regime postponement of execution administrative acts in an administrative dispute, contains a number of elements that significantly contribute to raising quality of the legal position of parties in administrative matters. One of the most important innovation is the establishment of an administrative court jurisdiction to decide on the request of the Prosecutor for a stay of execution of an administrative act challenged in administrative proceedings, particularly against administrative acts which appealed the appellate administrative body that has no suspensive effect. Regardless of some defects that can be seen in the legal regime of postponement of the execution of administrative decisions in administrative proceedings, which are related mainly to the lack of a legal remedy against a court decision on the request for stay of execution of administrative acts and the inability to use temporary measures in the administrative proceedings, with a lot of basis, however, it could be concluded that the new Law on Administrative Disputes created more than a solid legal basis for further promotion of legal security of the parties in administrative matters.

  9. Scanning electron microscopy investigation of canal cleaning after canal preparation with nickel titanium files

    Directory of Open Access Journals (Sweden)

    Živković Slavoljub

    2010-01-01

    Full Text Available Introduction. Root canal preparation is the most important phase of endodontic procedure and it consists of adequate canal space cleaning and shaping. In recent years, rotary instruments and techniques have gained importance because of the great efficacy, speed and safety of the preparation procedure. Objective. The aim of this research was to investigate the influence of different NiTi files on the canal wall cleaning quality, residual dentine debris and smear layer. Methods. The research was conducted on extracted human teeth in vitro conditions. Teeth were divided in 7 main groups depending on the kind of instruments used for root canal preparation: ProTaper, GT, ProFile, K-3, FlexMaster, hand ProTaper and hand GT. Root canal preparation was accomplished by crown-down technique. Prepared samples were assessed on scanning electron microscopy JEOL, JSM-6460 LV. The evaluation of dentine debris was done with 500x magnification, and the evaluation of smear layer with 1,000 times magnification. Quantitive assessment of dentine debris and smear layer was done according to the criteria of Hulsmann. Results. The least amount of debris and smear layer has been found in canals shaped with ProFile instruments, and the largest amount in canals shaped with FlexMaster instruments. Canal cleaning efficacy of hand GT and ProTaper files has been similar to cleaning efficacy of rotary NiTi files. Statistic analysis has shown a significant difference in amount of dentine debris and smear layer on the canal walls between sample groups shaped with different instruments. Conclusion. Completely clean canals have not been found in any tested group of instruments. The largest amount of debris and smear layer has been found in the apical third of all canals. The design and the type of endodontic instruments influence the efficacy of the canal cleaning.

    Adorno, C G; Yoshioka, T; Suda, H

    2010-05-01

    To investigate the vertical and horizontal distribution and the incidence of accessory canals in Japanese maxillary anterior teeth following root filling. The study included maxillary teeth; 69 central incisors, 61 lateral incisors and 31 canines. After the canal systems had been dyed and root canal instrumentation had been carried out, all prepared canals were filled with gutta-percha without using sealer. Transparent specimens were then obtained and examined with a digital microscope for horizontal and vertical distributions of accessory canals. The incidence of teeth with accessory canals in the apical 3 mm was 46%, 29% and 38% for the maxillary central incisors, lateral incisors and canines, respectively. The horizontal distribution was mainly buccal for central incisors, palatal for lateral incisors and distal and palatal for canines. There was a significant difference (P < 0.05) between the apical 3 mm and the rest of the root (16%, 20% and 19% for the maxillary central incisors, lateral incisors and canines, respectively) in terms of the presence of accessory canals. A high percentage of accessory canals can be found in apical 3 mm of the root. The horizontal distribution of accessory canals differed amongst the tooth types studied.

    This in vitro study compared debridement efficacies of a sonic irrigation technique (Vibringe; Cavex Holland BV, Haarlem, The Netherlands) with side-vented needle irrigation (SNI) in the mesiobuccal root of maxillary first molars. Twenty roots with narrow isthmuses (≤ 1/4 canal diameter) were selected using micro-computed tomography scanning. Collagen solution was injected into canals/isthmuses and reconstituted with NH(4)OH to simulate canal debris. Each root was sealed apically and embedded in polyvinyl siloxane simulating a closed-canal system. Canals were instrumented to size 40/.04 taper 1 mm short of the anatomic apex. The final irrigation was performed with the Vibringe or SNI. Roots were demineralized, sectioned at 6 levels (1.2-3.2 mm) from the anatomic apex, and stained using Masson trichrome stain. The areas occupied by canals and isthmus and the debris-containing areas were statistically analyzed with repeated-measures analyses using "irrigation technique" as the between factor and "canal level" as the within factor (α = 0.05). Canals had significantly more debris at 1.2 and 1.6 mm (P .05). Considerably more debris remained at 1.2 and 2.0 mm for the Vibringe (P < .05). A significant difference was observed between the canal and the isthmus (P < .001). There is no difference between the Vibringe and SNI in their overall debridement efficacy in apical one third of the mesiobuccal root of maxillary first molars. Published by Elsevier Inc.

    The human vestibular system is a sensory and equilibrium system that manages and controls the human sense of balance and movement. It is the main sensor humans use to perceive rotational and linear motions. Determining an accurate mathematical model of the human vestibular system is significant for research pertaining to motion perception, as the quality and effectiveness of the motion cueing algorithm (MCA) directly depends on the mathematical model used in its design. This paper describes the history and analyses the development process of mathematical semicircular canal models. The aim of this review is to determine the most consistent and reliable mathematical semicircular canal models that agree with experimental results and theoretical analyses, and offer reliable approximations for the semicircular canal functions based on the existing studies. Selecting and formulating accurate mathematical models of semicircular canals are essential for implementation into the MCA and for ensuring effective human motion perception modeling.

  13. Sugar receptor response of the food-canal taste sensilla in a nectar-feeding swallowtail butterfly, Papilio xuthus

    The feeding behavior in nectar-feeding insects is triggered by a sugar-receptor response in contact chemosensilla. The contact chemosensilla are distributed not only on tarsi and the outside of the proboscis but also on the inside of the food canal in Lepidoptera. Although the chemosensilla inside the food canal are assumed to detect sweet taste during the passage of nectar through the food canal, their electrophysiological function has received little attention. In the nectar-feeding Asian swallowtail butterfly, Papilio xuthus (Lepidoptera: Papilionidae), we found 15- to 30-μm-long sensilla neatly lined up along the inside galea wall, which forms the food canal in the proboscis. The receptor neurons of these sensilla responded to sucrose. We hypothesized that starch and sucrose compete with each other for a taste receptor site on the sensilla. When we added starch and sucrose to the food-canal sensilla, the electrophysiological responses of food-canal sensilla were inhibited in parallel with the food-sucking behavior of the butterflies. These results suggest that the food-canal sensilla are involved in the behavioral control of nectar-sucking in this butterfly species.

  16. A revisit on the current practice of dispute resolution and ADR in the Malaysian construction industry

    Directory of Open Access Journals (Sweden)

    Mohd Suhaimi Mohd Danuri

    2012-06-01

    Full Text Available The current dispute resolution procedures available in the Malaysian construction industry are mainly litigation and arbitration. In addition, the alternative dispute resolutions (ADR, namely mediation and adjudication, have also been introduced as the other methods for resolving disputes. The objective of this study is to examine the current practice of dispute resolution and ADR available in the Malaysian construction industry. The aim of this paper is two-fold: to report the current practice of dispute resolution and ADR, and identify the attributes of successful implementation of both mechanisms based on the perceptions of the Malaysian construction industry players. From the jurisprudence point of view, this study looks into the law as it is, in relation to the current practice of dispute resolution and ADR, by showing how those findings can be used to explain why improvement is needed to promote a successful and well received dispute resolution and ADR, and what lessons can be learnt, towards the formulation of a more viable methods for the Malaysian construction industry. NVivo software has been used to manage and organise the complete interview transcripts and facilitate the data analysis process for this study. Literature review reveals a continuous development of dispute resolution and ADR in the Malaysian construction industry, while, globally the industry has not only embraced ADR but also spearheaded the development of innovative forms of dispute avoidance mechanism. The findings of interviews show that locally, apart from litigation, the common types of ADR are arbitration, mediation and ad hoc mechanism. The findings also lead to the discovery of the following attributes: faster, less procedural, cost effective and enforceable; regulation and government's support; professionalism and ethic; training; and facility, that may promote a successful implementation of dispute resolution and ADR in Malaysia.

  17. The ability of 5% Tamarindus indica extract as cleaner of the root canal wall smear layer

    Full Text Available Tamarindus indica is one of traditional medicines. Pulpa tamaridorum consist of organic acid that is usually used as irrigant and to remove root canal wall smear layer. The aimed of this study was to elucidate the ability of 5% Tamarindus indica extract as a root canal irrigant to remove root canal wall smear layer. Eighteen tooth samples were cut on cervical line and divided into 2 then groups were prepared with K file and irrigated. Group 1 was irrigated by sterile aquabidest and group 2 was irrigated by 5% Tamarindus indica extract. Samples were cut longitudinally and formed 7 × 2× 2 mm specimen. Each specimen was photographed by scanning electron microscope, scored and summed. The total score obtained is used as the hygiene value of root canal wall. The collected data were statistically analyzed by using independent t test at 0.05 level. The result of the study showed there was a significant difference between 5% Tamarindus indica extract and sterile aquabidest (p < 0.05, the hygiene value of 5% Tamarindus indica extract was higher than sterile aquabidest. The conclusion of this investigation showed that 5% Tamarindus indica extract remove root canal wall smear layer.

  18. The fluid mechanics of root canal irrigation.

    Gulabivala, K; Ng, Y-L; Gilbertson, M; Eames, I

    2010-12-01

    Root canal treatment is a common dental operation aimed at removing the contents of the geometrically complex canal chambers within teeth; its purpose is to remove diseased or infected tissue. The complex chamber is first enlarged and shaped by instruments to a size sufficient to deliver antibacterial fluids. These irrigants help to dissolve dying tissue, disinfect the canal walls and space and flush out debris. The effectiveness of the procedure is limited by access to the canal terminus. Endodontic research is focused on finding the instruments and clinical procedures that might improve success rates by more effectively reaching the apical anatomy. The individual factors affecting treatment outcome have not been unequivocally deciphered, partly because of the difficulty in isolating them and in making the link between simplified, general experimental models and the complex biological objects that are teeth. Explicitly considering the physical processes within the root canal can contribute to the resolution of these problems. The central problem is one of fluid motion in a confined geometry, which makes the dispersion and mixing of irrigant more difficult because of the absence of turbulence over much of the canal volume. The effects of treatments can be understood through the use of scale models, mathematical modelling and numerical computations. A particular concern in treatment is that caustic irrigant may penetrate beyond the root canal, causing chemical damage to the jawbone. In fact, a stagnation plane exists beyond the needle tip, which the irrigant cannot penetrate. The goal is therefore to shift the stagnation plane apically to be coincident with the canal terminus without extending beyond it. Needle design may solve some of the problems but the best design for irrigant penetration conflicts with that for optimal removal of the bacterial biofilm from the canal wall. Both irrigant penetration and biofilm removal may be improved through canal fluid

  2. Territorial disputes, identity conflicts, and violence in surfing

    Directory of Open Access Journals (Sweden)

    Marília Martins Bandeira

    2014-03-01

    Full Text Available Aggressive manifestations of localism are a current concern among surfers and are becoming well known as a result of specialized media. The objective of this paper was to investigate this phenomenon through the examination of a specific case and empirical fieldwork that was conducted for an ethnography of São Paulo surfers. The data were obtained via participant observations and open interviews. The results indicate that conflicts generally begin as disputes over the best waves. Surfing has a general rule of "wave priority criteria," based on spatial positioning. However, this universal rule may be intentionally broken depending on surfers' sociability. Ethnic and class differences based on historical processes can exist in oppositional relationships among surfers and are manifested by categories of accusation or identity (in São Paulo's case, local, haole, roots,prego,and playboy. However, this category attribution is contextual and interchangeable because surfers circulate between groups and beaches while searching for waves.

  3. Disputes And The Territory. The Case Of Deseado Massif

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available This article examines some of the problems presented in the area of the Deseado Massif, in the north-centre of the province of Santa Cruz, Argentina's southern Patagonia, a space in which the metalliferous mega-mining develops, almost exclusively, as the only possible activity. In this context, we will analyze the disputes that untie "in and for" the territory due to this activity, in a context where the multiplicity of people involved in this space make the conflicts more complex. In this scenario, the concept of territory proposed by Bernardo Mançano Fernándes, supported by a critical perspective, allows us to disrupt the plot of the conflict, under a qualitative methodology based on secondary sources. Regarding the results, this article describes the operation of the rentier mentality, the violence and the trap of abundance in regions with extractive vocation.

  4. Mediation as a method of parent intervention in children's disputes.

    Siddiqui, Afshan; Ross, Hildy

    2004-03-01

    This study examined the feasibility and short-term effects of mothers' use of mediation to help children (5 to 8 years) resolve disputes. Families in which mothers were trained to use mediation were compared with control families on intervention strategies at home and discussion of a recurring conflict in the laboratory. With training, mothers could use mediation strategies, and these strategies were favored by both mothers and children. Children responded appropriately to mediation (reasoning, discussing emotions, and understanding motivations more often than in control families). Mediation empowered children, particularly younger siblings, to solve conflict issues. Although questions of the long-term implications of mediation remain, this study suggests that mediation may be a powerful parenting tool, promoting social understanding and productive conflict resolution.

    Yang, Zhang

    Because the disputes and case facts of construction project contracts are intricate, there are many new conditions and problems involved in application of law, it's very difficult to dispose in the judicial practice with the difference in judicial theories and understanding spirit of the laws, and the juridical criterions of judgment are not unified in the courts of various regions. As judicial organs, people's courts should keep pace with the times, take precautions, and do well investigations and researches on such application of law in such cases in order to give full play to the judicial function, to safeguard the lawful rights and interests of disadvantaged groups and to promote the sustained, rapid and sound development of real estate market.

    Heading Abstract.The aim of this study was to assess imaging findings of posterior semicircular dehiscence on computed tomography and to evaluate incidence of posterior and superior semicircular canal dehiscence in patients presenting with vertigo, sensorineuronal hearing loss or in a control group without symptoms related to the inner ear. Computed tomography was performed in 507 patients presenting either with vertigo (n=128; 23 of these patients suffered also from sensorineuronal hearing loss), other symptoms related to the inner ear, such as hearing loss or tinnitus (n=183) or symptoms unrelated to the labyrinth (n=196). All images were reviewed for presence of dehiscence of the bone, overlying the semicircular canals. Twenty-nine patients had superior semicircular canal dehiscence. Of these patients, 83% presented with vertigo, 10% with hearing loss or tinnitus and the remaining 7% with symptoms unrelated to the inner ear. In 23 patients dehiscence of the posterior semicircular canal was encountered. Of these patients, 86% presented with vertigo, 9% with hearing loss or tinnitus and 5% with symptoms unrelated to the inner ear. Defects of the bony overly are found at the posterior semicircular canal, in addition to the recently introduced superior canal dehiscence syndrome. Significant prevalence of vertigo in these patients suggests that posterior semicircular canal dehiscence can cause vertigo, similar to superior semicircular canal dehiscence. (orig.)

  7. Analyzing endosonic root canal file oscillations: an in vitro evaluation.

    Lea, Simon C; Walmsley, A Damien; Lumley, Philip J

    2010-05-01

    Passive ultrasonic irrigation may be used to improve bacterial reduction within the root canal. The technique relies on a small file being driven to oscillate freely within the canal and activating an irrigant solution through biophysical forces such as microstreaming. There is limited information regarding a file's oscillation patterns when operated while surrounded by fluid as is the case within a canal root. Files of different sizes (#10 and #30, 27 mm and 31 mm) were connected to an ultrasound generator via a 120 degrees file holder. Files were immersed in a water bath, and a laser vibrometer set up with measurement lines superimposed over the files. The laser vibrometer was scanned over the oscillating files. Measurements were repeated 10 times for each file/power setting used. File mode shapes are comprised of a series of nodes/antinodes, with thinner, longer files producing more antinodes. The maximum vibration occurred at the free end of the file. Increasing generator power had no significant effect on this maximum amplitude (p > 0.20). Maximum displacement amplitudes were 17 to 22 microm (#10 file, 27 mm), 15 to 21 microm (#10 file, 31 mm), 6 to 9 microm (#30 file, 27 mm), and 5 to 7 microm (#30, 31 mm) for all power settings. Antinodes occurring along the remaining file length were significantly larger at generator power 1 than at powers 2 through 5 (p < 0.03). At higher generator powers, energy delivered to the file is dissipated in unwanted vibration resulting in reduced vibration displacement amplitudes. This may reduce the occurrence of the biophysical forces necessary to maximize the technique's effectiveness. Copyright (c) 2010 American Association of Endodontists. Published by Elsevier Inc.

  8. Management of C-shaped canals: Two case reports

    Directory of Open Access Journals (Sweden)

    Nilesh Suryakant Kadam

    2013-01-01

    Full Text Available A C-shaped canal with varying configuration is commonly observed in single-rooted mandibular second molars. Cooke and Cox (1979 first documented the C-shaped canal in endodontic literature. The presence of high incidence of transverse anastomoses, lateral canals, and apical deltas makes it difficult to clean and seal the root canal system in these teeth. The main reason for failure in endodontic treatment of mandibular second molars is the inability to detect the presence of C-shaped canals prior to an endodontic therapy. This case report presents successful management of two rare cases of C-shaped canal configurations.

  9. Islamic Banking in Malaysia: Arbitration Resolution of Financial Disputes and Obstacles to its Spread

    Directory of Open Access Journals (Sweden)

    Elena V. Sitkareva

    2017-01-01

    Full Text Available Purpose: the article examines the main problems associated with the extension of arbitration of domestic and international Islamic financial disputes in Malaysia. These include the specific features of the legal regulation of Malaysia, excluding the resolution of certain categories of cases by way of arbitration, and the lack of legal certainty in the submission of cross-border contracts in the field of Islamic banking to Sharia law.To achieve this goal in the article you must accomplish the following tasks: to determine whether there are institutions in Malaysia providing arbitration services for disputes in the field of Islamic banking; investigate the reasons for the unwillingness of the parties to a financial dispute to transfer it to arbitration; to identify the main problems of transferring a cross-border financial dispute to international arbitration; to study the practice of international arbitration on this issue.Methods: this article is based on an interdisciplinary concept of research, which allowed to distinguish the distinctive features of the legal regulation of the settlement of financial disputes in Malaysia.Results: currently the popularization of arbitration permits for domestic and international financial disputes in Malaysia faces difficulties due to both internal reasons and the traditional approach of Islamic banks to include in contracts the reservation of subordination of the provisions of the contract to the law of England or the United States in conjunction with the reservation clause financial disputes in the courts and arbitration of these states. Nevertheless, one can assume with great confidence that, following the development of Islamic banking, so-called Islamic arbitration will spread in Malaysia.Conclusions and Relevance: the materials outlined in the article show the special role of arbitration in resolving domestic and international disputes in the field of Islamic banking. Practical application of its results

  10. What We Can Learn from Artificial Lateral Line Sensor Arrays.

    Klein, A T; Kaldenbach, F; Rüter, A; Bleckmann, H

    2016-01-01

    The lateral line system of fish is important for many behaviors, including spatial orientation, prey detection, intraspecific communication, and entraining. With aid of the lateral line, fish perceive minute water motions. The smallest sensory unit of the lateral line is the neuromast, which occurs freestanding on the skin and in fluid-filled canals. We have built artificial lateral line canal systems that can be used to measure spatiotemporal flow patterns. Those patterns can, for instance, be used to distinguish between different environments and upstream objects.

  11. Study of root canal accessibility in human primary molars.

    Aminabadi, Naser A; Farahani, Ramin M Z; Gajan, Esrafil B

    2008-03-01

    The aim of the present study was to provide a general scheme for pulpectomy of primary molars that may be useful for decision-making about negotiation of root canals and selection of appropriate instruments. A total of 160 vital primary molars in 85 patients (40 males, 45 females) aged 4-6 years were selected. After taking primary radiographs, local anesthesia was induced, and the teeth were isolated using a rubber dam. Canal accessibility index (CAI) and tooth accessibility index (TAI) were calculated according to initial file size. Mandibular first molars had either three canals (79.2%) or four canals (20.8%), and all second molars had four canals. Maxillary first molars had three canals and second molars had either three canals (70.9%) or four canals (29.1%). Lower accessibility of the mandibular first molar distobuccal root accounted for the lower accessibility of these teeth in comparison with mandibular second molars. While three-canal maxillary second molars were more accessible due to the lower accessibility of the distobuccal canal of the maxillary first molar, poor accessibility of the distal canal in four-canal second molars was responsible for the difficult accessibility of these teeth. In conclusion, it seems that the accessibility of a single canal in each tooth determines the difficulty of accessibility for any given tooth. Moreover, while primary second molars are more accessible than first molars, all of them are negotiable.

    2017-01-01

    Successful root canal treatment depends on proper cleaning, disinfecting and shaping of the root canal space. Pulpless teeth have lower dentin microhardness value compared to that of vital teeth. A material which can cause change in dentin composition may affect the microhardness. Thus the aim of this study was to evaluate and compare the effect of two root canal sealers on dentin microhardness. Forty two single rooted teeth were selected and divided into 3 equal groups; Apexit, iRootSP and control groups (n=14) Each group was then divided into 2 subgroups according to the post evaluation period; 1 week and 2 months (n=7). Root canal procedure was done in the experimental groups and obturation was made using either; Apexit, iRootSP or left unprepared and unobturated in the control group. Roots were sectioned transversely into cervical, middle and apical segments. The three sections of each root were mounted in a plastic chuck with acrylic resin. The coronal dentin surfaces of the root segments werepolished. Microhardness of each section was measured at 500 µm and 1000 µm from the canal lumen. Four way-ANOVA revealed that different tested sealer materials, canal third, measuring distance from the pulp and time as independent variables had statistically non significant effect on mean microhardness values (VHN) at p≤0.001. Among iRootSP groups there was a statistically significant difference between iRoot SP at coronal root portion (87.79±17.83) and iRoot SP at apical root portion (76.26±9.33) groups where (p=0.01). IRoot SP at coronal canal third had higher statistically significant mean microhardness value (87.79±17.83) compared to Apexit at coronal third (73.61±13.47) where (p=0.01). Root canal sealers do not affect dentin microhardness. Key words:Root canal, dentin, sealers, microhardness, bioceramic.

    This case report presents surgical endodontic management outcomes of maxillary incisors that were infected via the lateral canals. Two cases are presented in which endodontically-treated maxillary central incisors had sustained lateral canal infections. A surgical endodontic treatment was performed on both teeth. Flap elevation revealed vertical bone destruction along the root surface and infected lateral canals, and microscopy revealed that the lateral canals were the origin of the lesions. After the infected lateral canals were surgically managed, both teeth were asymptomatic and labial fistulas were resolved. There were no clinical or radiographic signs of surgical endodontic management failure at follow-up visits. This case report highlights the clinical significance and surgical endodontic management of infected lateral canal of maxillary incisor. It is important to be aware of root canal anatomy variability in maxillary incisors. Maxillary central incisors infected via the lateral canal can be successfully managed by surgical endodontic treatment.

  19. Apologies, Mediation and the Law: Resolution of Civil Disputes

    Full Text Available Mediation is a process that provides opportunities for parties to civil disputes to engage in dialogue that can satisfy their expectations and needs for apologies. While the literature on law and apology identifies why and ways in which the process can be beneficial, there are concerns associated with apologies offered in mediation. This article provides an overview of the apology and mediation literature in which these benefits and concerns are explored and the psychological research that reveals the complexity of apologies. We use case examples that illustrate this complexity and indicate ways that mediators working with parties in mediation who have indicated that apologies are important to them, might work with this. The article also reflects on the ways that the law interacts with apologies in the mediation of private law disputes and concludes that the law plays a significant indirect role in supporting parties who seek an apology as an outcome of mediationLa mediación es un proceso que ofrece a las partes implicadas en disputas civiles la oportunidad de entablar un diálogo que permita satisfacer sus expectativas y necesidades de disculpas. Mientras la literatura sobre derecho y disculpas identifica el porqué y las formas en las que el proceso puede ser beneficioso, existen preocupaciones asociadas a las disculpas ofrecidas en la mediación. Este artículo ofrece una visión de la literatura sobre disculpas y mediación, que analiza estos beneficios y preocupaciones, y de la investigación psicológica que muestra la complejidad de las disculpas. Se usan ejemplos de casos que ilustran esta complejidad e indican formas en las que podían aplicarlos los mediadores que trabajan en mediaciones en las que las partes han indicado que las disculpas son importantes para ellos. Este artículo también refleja las formas en las que el derecho interactúa con las disculpas en la mediación entre disputas de derecho privado y llega a la conclusi

    The aim of this study was to compare sizes of the first instrument with or without a taper that binds at the apical constriction of a root canal after coronal flaring. A total of 310 canals were evaluated in patients presenting for root canal therapy. Canals with intact apices were selected. After gaining straight line endodontic access, the coronal third was flared using Gates-Glidden drills. Working length was determined using an apex locator. ISO Standard K-files (tapered) were passively introduced into the canals starting with a No. 15 file. The first K-file size to bind against the canal walls without pushing and to reach the working length was recorded as the FKFB (First K File to Bind). Next, ISO Standard Lightspeed files (non-tapered instruments) starting with No. 20 were then gently introduced by hand to each canal in ascending order to the working length. The first size of a Lightspeed instrument to bind against the canal walls and reach the working length was recorded as FLSB (First Light Speed to Bind). In all instances a larger file was introduced to ensure it could not reach the same depth (i.e., working length). Statistical analysis was carried out using a univariate analysis of variance (ANOVA). The average size of the FLSB to bind against the canal walls first at the working length was approximately two ISO sizes larger than the FKFB (Papical canal diameter plays a major factor in identifying the extent of final apical shaping. Because the first non-tapered instrument that binds the apical constriction is larger than the corresponding tapered instrument, it better reflects the actual narrow apical diameter of the canal. The initiation of canal instrumentation with a K-file size three sizes beyond the mean values of the FLSB will result in greater final enlargement of the canal compared to starting with the FKFB. This increased canal enlargement facilitates improved mechanical and chemical cleansing of the root canal ensuring removal of more

  2. Mendacious moms or devious dads? Some perplexing issues in child custody/sexual abuse allegation disputes.

    Science.gov (United States)

    Penfold, P S

    1995-08-01

    To explore relevant literature about sexual abuse allegations arising in child custody disputes. A literature review of false allegations is given and the contribution of gender bias to this issue is discussed. The role a child psychiatrist may play in such cases is outlined. Contrary to much popular and professional opinion, sexual abuse allegations are found in only 2% of child custody disputes, and, of these, 8% to 16.5% are false. While false allegations arise for a variety of reasons, the word "false" can imply both erroneous and deceitful activities. This ambiguity, along with gender bias, may lead to disbelief of, and blame towards, parents who report sexual abuse in the context of a dispute about custody or access. The child psychiatrist who testifies in such custody disputes should have caution, humility, and an open mind both in the courtroom and in dealing with other professionals working in this area.

  5. The Role of Customary Arbitration in the Resolution of Disputes among Nigerian Indigenous Communities

    Directory of Open Access Journals (Sweden)

    T. Kehinde Adekunle

    2015-12-01

    Full Text Available Central to the issue of resolution of any disputes is the mechanism adopted in handling it. Customary arbitration is, thus, one of the recognised methods of resolving disputes among the indigenes of Nigeria. Unlike the Western adversarial method of settling disputes under which the winner-takes-all, customary arbitration aimed at reconciling the parties to disputes after effecting settlement. The question, however, is whether customary arbitration has any relevance among Nigerian indigenous communities and whether it has made any impact on the maintenance of societal equilibrium. This paper, therefore, examined the issues involved in customary arbitration such as the ingredients that make it work, conditions of its validity and its effect on the state of the society with a view to making it work more effectively among the indigenes.

    Full Text Available This study discusses about an Alternative Dispute Resolution in BanyumasRegency as a non-litigation dispute resolution. The problem observed was a breakthroughtaken by the Society in Banyumas Regency in overcoming the so far deadlock of lawenforcement and the attitude of not trusting the justice enforcement. It has been a publicsecret that the dispute resolutions employing the legal centralism paradigm have beendominated by the judicial network.

    The present study investigated emotions as they were made visible and responded to in a particular institutional setting. Following discursive psychology the aim was to provide a rigorous account of emotion as observable in talk-in-interaction. Using conversation analysis a focus was on the temporality of emotion in turns of talk and over the course of an interaction. Data were recordings and transcriptions of calls to a dispute resolution service for consumers' problems with electricity and gas. The analysis identified systematic practices callers' use for describing and doing upset. Call-takers rarely displayed emotion in the body of the calls and typically responded to institutionally relevant aspects of the callers' troubles and not the emotional ones. In the absence of any kind of endorsement of the callers' emotional stance, emotionality could escalate. Emotional affiliation regularly occurred at the end of the calls. The escalation of emotion in the absence of its endorsement and the occurrence of emotional affiliation at call-closing evidences a sequential property of emotion that has been largely overlooked. © 2014 The British Psychological Society.

  5. Democracy and secularism: remarks on an ongoing dispute

    2014-06-01

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2014v13n1p141This paper focus on the disputed issue concerning the proper role of religion in politics, confronting the contributions of three major contemporary political thinkers about democracy and secularism. I present, first, Charles Taylor’s characterization of secularist regimes as attempts to secure the basic principles of the modern moral order. Next, I argue that John Rawls’s growing interest in the relation between religion and democracy led him to an even more inclusive view of public reason. Thirdly, I show that Jürgen Habermas preserves a distinction between faith and knowledge that proves essential to grasping the debate over the place of religion in the public sphere. All three thinkers are concerned with the appropriate forum for the basic political language of the secular state. In a nutshell, my interpretation highlights a much greater proximity between Habermas and Rawls on political justification, on the one hand, and between the former and Taylor regarding the normative basis for the secular state, on the other hand, than their various interventions seem to indicate.

  6. Judicial privilgies of Saxons in mixed disputes in Medieval Serbia

    Directory of Open Access Journals (Sweden)

    Katančević Andreja

    2015-01-01

    Full Text Available Based on the contemporary testimonies, wealth of the Serbian medieval kings was significantly increased by exploitation of number of precious metal mines that existed in their realm. Beginnings of the mine exploitation in medieval Serbia are related to the settlements of Saxon miners. Saxons were mining experts in medieval Europe who worked in distant mines far away from their homeland Saxony. They worked in this profitable mining business not only in Serbia, but also in Bohemia, Hungary (Transylvania and modern Slovakia and Bosnia. The settlement of Saxons in Serbia occurred in time of the reign of King Stefan Uros I (1234-1276. Although without preserved sources which could directly support this thesis, Serbian historiography advocates that certain privileges were granted to the Roman Catholic Saxons at the time of their migration in orthodox Serbia. It appears that these privileges included self-government, freedom of religion, and mining concessions. Also judicial privileges are often mentioned in historiography especially the right of Saxons to one half of the members of their ethnicity in judicial collegium and jury in the case of a dispute with member of another ethic group. This paper attempts to test the thesis related to composition of mixed courts and juries by applying historical method, and linguistic, systemic and historical interpretation of the sources such as King's Charters issued to Dubrovnik, Dusan's Code and Despot Stefan's Mining Code.

  7. The crazy project – Canal Istanbul

    Directory of Open Access Journals (Sweden)

    Seda Kundak

    2011-10-01

    Full Text Available It was late April 2011 when “the Crazy Project - Canal Istanbul” was proposed by the Prime Minister of Turkey, during his election campaign.  Although the idea of an artificial canal is not new, since it is initiated without any consensus between the people and institutions in Istanbul, the project immediately set a large number of debates. These vary from the legitimacy of decentralization of governance, to potential impacts of the canal on international politics, economy, environment and urban life.  Regarding past infrastructure projects in Istanbul, such large scale investments have caused extensive acceleration in construction sector in one hand and social and economic shifts on the other.  In this paper, the Canal Istanbul Project is evaluated according to basic motivations and claims of the PM, multi-perspective view through challenges and limitation that the project is likely to face with and speculations on implementation approach. The final discussion on the project is based on benefits/losses of Istanbul once the project will be implemented.

  12. Divided parents, shared children
    Conflicting approaches to relocation disputes in the USA

    Directory of Open Access Journals (Sweden)

    Theresa Glennon

    2008-06-01

    Full Text Available Custody relocation disputes pose intractable dilemmas for courts in a highly mobile society. The custodial parent, most often a woman, seeks self-determination, freedom of movement and a continued custodial relationship with the child. The non-custodial parent seeks to preserve a geographically close relationship with the child. Courts must identify the best interests of the children amidst these multiple and conflicting interests. They make decisions that may determine the course of custodial parents’ lives, affecting remarriage, employment, education, and proximity to family. A narrow doctrinal focus on children’s best interests ignores these key aspects of relocation disputes. This article examines the varied legislative and judicial approaches to relocation disputes in the US and proposed principles for resolution of these disputes. It reviews scholarship analyzing relocation disputes from a wide range of perspectives, including: conflicting social science research; competing ideologies of the post-divorce family; alternative dispute resolution; parents’ constitutional rights; domestic violence victims; and proposals to eliminate geographic presumptions and remedy the economic effect of restraints on relocation. Relocation doctrine in the US should be realigned to address these complex perspectives. States should also assist post-divorce families to support children through the common experience of relocation.

    Science.gov (United States)

    Cegon, Amanda Brooke

    El Paso County Water Improvement District No. 1 (EPCWID No.1) delivers the Rio Grande water for agricultural production and urban uses through numerous networked irrigation canals. Of the nearly 86 billion gallons of water released annually for irrigation uses in Texas, billions are lost due to evaporation and seepage in unlined canals with 56 million gallons of the billions are lost in Franklin Canal annually due to improper lining and sediment variation of the canals. To characterize seepage patterns and identify areas of high seepage, Electrical Resistivity, Ground Truthing via soil sample analysis were used along three, half-mile long sectioned canals during irrigation and non-irrigation seasons. The data lines acquired were processed in EARTHIMAGER 2D to create 2D vertical resistivity inversion profiles to locate potential areas of high seepage/high resistivity. The research results will help El Paso County Water Improvement District No. 1 to develop management strategies to conserve water and improve the delivery efficiency systems which leads to economic growth in the Rio Grande Basin.

    Objectives: Lumbar punctures (LPs) are frequently performed in neonates and often result in traumatic haemorrhagic taps. Knowledge of the distance from the skin to the middle of the spinal canal (mid-spinal canal depth - MSCD) may reduce the incidence of traumatic taps, but there is little data in extremely premature or low birth weight neonates. Here, we determined the spinal canal depth at post-mortem in perinatal deaths using magnetic resonance imaging (MRI). Patients and methods: Spinal canal depth was measured in 78 post-mortem foetuses and perinatal cases (mean gestation 26 weeks; mean weight 1.04 kg) at the L3/L4 inter-vertebral space at post-mortem MRI. Both anterior (ASCD) and posterior (PSCD) spinal canal depth were measured; MSCD was calculated and modelled against weight and gestational age. Results: ASCD and PSCD (mm) correlated significantly with weight and gestational age (all r > 0.8). A simple linear model MSCD (mm) = 3 Multiplication-Sign Weight (kg) + 5 was the best fit, identifying an SCD value within the correct range for 87.2% (68/78) (95% CI (78.0, 92.9%)) cases. Gestational age did not add significantly to the predictive value of the model. Conclusion: There is a significant correlation between MSCD and body weight at post-mortem MRI in foetuses and perinatal deaths. If this association holds in preterm neonates, use of the formula MSCD (mm) = 3 Multiplication-Sign Weight (kg) + 5 could result in fewer traumatic LPs in this population.

    The cervical spine in Chiari I patient with syringomyelia has significantly different anteroposterior diameters than it does in Chiari I patients without syringomyelia. We tested the hypothesis that patients with idiopathic syringomyelia (IS) also have abnormal cervical spinal canal diameters. The finding in both groups may relate to the pathogenesis of syringomyelia. Local institutional review boards approved this retrospective study. Patients with IS were compared to age-matched controls with normal sagittal spine MR. All subjects had T1-weighted spin-echo (500/20) and T2-weighted fast spin-echo (2000/90) sagittal cervical spine images at 1.5 T. Readers blinded to demographic data and study hypothesis measured anteroposterior diameters at each cervical level. The spinal canal diameters were compared with a Mann-Whitney U test. The overall difference was assessed with a Friedman test. Seventeen subjects were read by two reviewers to assess inter-rater reliability. Fifty IS patients with 50 age-matched controls were studied. IS subjects had one or more syrinxes varying from 1 to 19 spinal segments. Spinal canal diameters narrowed from C1 to C3 and then enlarged from C5 to C7 in both groups. Diameters from C2 to C4 were narrower in the IS group (p < 0.005) than in controls. The ratio of the C3 to the C7 diameters was also smaller (p = 0.004) in IS than controls. Collectively, the spinal canal diameters in the IS were significantly different from controls (Friedman test p < 0.0001). Patients with IS have abnormally narrow upper and mid cervical spinal canal diameters and greater positive tapering between C3 and C7. (orig.)

    Full Text Available It is very important that the dentists have sufficient information about possible variations in the expected root canal configurations in order to achieve success in endodontic treatment. In addition to having adequate knowledge on the variations of the root canal anatomy, periapical radiographs from different angles, careful examination of the pulp chamber floor, and use of dental operation microscope during the procedure are also important factors that contribute to the diagnosis of the additional roots and canals. The aims of this article are to present the diagnostic approach and root canal treatments of two maxillary first premolar teeth with three canals in two patients.

  19. Endodontic treatment options after unsuccessful initial root canal treatment: Alternatives to single-tooth implants.

    2016-03-01

    Initial root canal treatment is highly successful, appreciated by patients, and cost-effective, but failures occur. Should a tooth with unsuccessful initial root canal treatment be treated by means of other endodontic procedures or be replaced by a single-tooth implant? Results from systematic reviews of the outcomes of nonsurgical retreatment, apical surgery, replantation, and autotransplantation show high tooth survival rates. Nonsurgical retreatment generally is prioritized before surgical endodontic treatment. Microsurgical endodontic treatment is superior to traditional surgical endodontic treatment and has high survival rates. Intentional replantation remains a viable alternative to extraction. Autotransplantation has a place, particularly in growing patients with an appropriate donor tooth. Single-tooth implants have higher survival rates, but the natural state has intrinsic value. The first-line treatment option after failure of initial root canal treatment is nonsurgical retreatment. Endodontic surgery, intentional replantation, and autotransplantation should be considered before extraction and replacement by a single-tooth implant. Comprehensive case assessment, evaluation of all endodontic options, and risk assessment for caries and periodontal disease are always necessary when choosing the optimal treatment for a patient when initial root canal treatment has failed to heal.

    To evaluate changes in the spinal canal in cases of L5 spondylolysis, as seen on sagittal MR images. We retrospectively analysed the MR findings of 27 patients suffering from L5 spondylolysis without spondylolisthesis and compared them with 100 control subjects. Spondylolysis had been confirmed by conventional radiography. On midsagittal MR images, sagittal canal ratio (SCR) was defined as midsagittal canal diameter at L5 devided by that at L1. We analysed the frequency of posterior epidural fat deposition(posterior epidural fat between the posterior margin of the dural sac and the anterior cortical margin of the spinous process on the midsagittal line), and compared this with the frequency in 100 control subjects. Mean SCR value in 27 patients with L5 spondylolysis(1.22) was significantly greater than 100 control subjects(0.96, p<0.001). Mean SCR value in 17 patients with L5 spondylolysis and posterior epidural fat deposition(1.27) was significantly higher than in nine control subjects with posterior epidural fat deposition(0.97). Posterior epidural fat deposition was more frequently indentified in patients with L5 spondylolysis(63%) than in control subjects(9%). The possibility of L5 spondylolysis is suggested when on midsaggital MR imaging, the anteroposterior diameter of the L5 spinal canal is seen to be widened and posterior epidural fat deposition is noted.

  1. Numerical modeling of the 1964 Alaska tsunami in western Passage Canal and Whittier, Alaska

    Full Text Available A numerical model of the wave dynamics in Passage Canal, Alaska during the Mw 9.2 megathrust earthquake is presented. During the earthquake, several types of waves were identified at the city of Whittier, located at the head of Passage Canal. The first wave is thought to have been a seiche, while the other two waves were probably triggered by submarine landslides. We model the seiche wave, landslide-generated tsunami, and tectonic tsunami in Passage Canal and compute inundation by each type of wave during the 1964 event. Modeled results are compared with eyewitness reports and an observed inundation line. Results of the numerical experiments let us identify where the submarine landslides might have occurred during the 1964 event. We identify regions at the head and along the northern shore of Passage Canal, where landslides triggered a wave that caused most of the damage in Whittier. An explanation of the fact that the 1964 tectonic tsunami in Whittier was unnoticed is presented as well. The simulated inundation by the seiche, landslide-generated tsunami, and tectonic tsunami can help to mitigate tsunami hazards and prepare Whittier for a potential tsunami.

  2. A new system for classifying tooth, root and canal anomalies.

    Understanding the normal anatomical features as well as the more unusual developmental anomalies of teeth, roots and root canals is essential for successful root canal treatment. In addition to various types of root canal configuration and accessory canal morphology, a wide range of developmental tooth, root and canal anomalies exists, including C-shaped canals, dens invaginatus, taurodontism, root fusion, dilacerations and palato-gingival grooves. There is a direct association between developmental anomalies and pulp and periradicular diseases that usually require a multidisciplinary treatment approach to achieve a successful outcome. A number of classifications have categorized tooth, root and canal anomalies; however, several important details are often missed making the classifications less than ideal and potentially confusing. Recently, a new coding system for classifying root, root canal and accessory canal morphology has been introduced. The purpose of this article is to introduce a new system for classifying tooth, root and canal anomalies for use in research, clinical practice and training, which can serve as complementary codes to the recently described system for classifying root, as well as main and accessory canal morphology. © 2017 International Endodontic Journal.

    Measure the space direction of semicircular canals to provide the anatomical basis for the diagnosis and treatment of BPPV. We calculated angles among semicircular canals of 24 patients using MRI scaning with 3D-CISS sequence. The angle between the left and right posterior semicircular canals was 106.61 degress ± 8.58 degrees, so the angle among the posterior semicircular canals and sagittal head plane was 53.31 degrees ± 4.29 degrees. Pairs of contralateral synergistic canal planes were not parallel, forming 171.67 degrees ± 4.36 degrees between the left and right horizontal semicircular canal planes, 154.37 degrees ± 10.87 degrees between the left posterior and right anterior semicircular canal planes and 156.84 degrees ± 9.34 degrees between the right posterior and left anterior semicircular canal planes. Our measurement of the angles among semicircular canals coincided with those of previous reports. The angles between contralateral synergistic canal planes were close to parallel, but the angle between the posterior semicircular canals and sagittal head plane was great than 45 degrees that traditionally thought to be.

    OBJECTIVE To analyze the regional governance of the health systemin relation to management strategies and disputes. METHODOLOGICAL PROCEDURES A qualitative study with health managers from 19 municipalities in the health region of Bahia, Northeastern Brazil. Data were drawn from 17 semi-structured interviews of state, regional, and municipal health policymakers and managers; a focus group; observations of the regional interagency committee; and documents in 2012. The political-institutional and the organizational components were analyzed in the light of dialectical hermeneutics. RESULTS The regional interagency committee is the chief regional governance strategy/component and functions as a strategic tool for strengthening governance. It brings together a diversity of members responsible for decision making in the healthcare territories, who need to negotiate the allocation of funding and the distribution of facilities for common use in the region. The high turnover of health secretaries, their lack of autonomy from the local executive decisions, inadequate technical training to exercise their function, and the influence of party politics on decision making stand as obstacles to the regional interagency committee’s permeability to social demands. Funding is insufficient to enable the fulfillment of the officially integrated agreed-upon program or to boost public supply by the system, requiring that public managers procure services from the private market at values higher than the national health service price schedule (Brazilian Unified Health System Table). The study determined that “facilitators” under contract to health departments accelerated access to specialized (diagnostic, therapeutic and/or surgical) services in other municipalities by direct payment to physicians for procedure costs already covered by the Brazilian Unified Health System. CONCLUSIONS The characteristics identified a regionalized system with a conflictive pattern of governance and

  6. Confidence in Alternative Dispute Resolution: Experience from Switzerland

    Full Text Available Alternative Dispute Resolution plays a crucial role in the justice system of Switzerland. With the unified Swiss Code of Civil Procedure, it is required that each litigation session shall be preceded by an attempt at conciliation before a conciliation authority. However, there has been little research on conciliation authorities and the public's perception of the authorities. This paper looks at public confidence in conciliation authorities and provides results of a survey conducted with more than 3,400 participants. This study found that public confidence in Swiss conciliation authorities is generally high, exceeds the ratings for confidence in cantonal governments and parliaments, but is lower than confidence in courts.Since the institutional models of the conciliation authorities (meaning the organization of the authorities and the selection of the conciliators differ widely between the 26 Swiss cantons, the influence of the institutional models on public confidence is analyzed. Contrary to assumptions based on New Institutional-ism approaches, this study reports that the institutional models do not impact public confidence. Also, the relationship between a participation in an election of justices of the peace or conciliators and public confidence in these authorities is found to be at most very limited (and negative. Similar to common findings on courts, the results show that general contacts with conciliation authorities decrease public confidence in these institutions whereas a positive experience with a conciliation authority leads to more confidence.The Study was completed as part of the research project 'Basic Research into Court Management in Switzerland', supported by the Swiss National Science Foundation (SNSF.

    The main purpose of this study is to investigate the prevalence of medical disputes among plastic surgeons in Taiwan and to elucidate their perspectives regarding the influence of medical litigation media coverage on the physician-patient relationship. A self-administered questionnaire was distributed among plastic surgeons attending a series of continuing education training lectures organized by the Taiwan Society of Plastic Surgery in 2015. Of the 109 respondents, over a third (36.4%) had previously experienced a medical dispute. The vast majority of both physicians who had medical disputes (77.1%) and those who did not (72.1%) felt that the media tends to be supportive of patients in their reporting, and 37.1% of all plastic surgeons felt that the media always portrays the patient as a victim. Respondents who experienced medical disputes in this study felt that the top five leading causes of the high incidence of medical disputes were patient disappointment with procedure results (81.1%), insufficient patient psychological preparation or emotional instability (61.7%), inadequate risk communication on the part of the physician (64.9%), patient uneasiness with the procedure or perception of carelessness (60.6%), and insufficient physician training or incorrect medical evaluation (57.4%). Over a third of the respondents had previously experienced a medical dispute. This study highlights the perception among plastic surgeons that the media reporting of medical disputes and medical litigation is biased in favor of the patients, with 37.1% of the plastic surgeons surveyed opining that patients are always cast as victims.

    Anal canal epidermoid carcinomas represent 1.2% of digestive cancers and 6% of ano-rectal cancers. For localized diseases, the treatment is based on radiotherapy with or without chemotherapy (5-FU and cisplatin or mitomycin), according to tumour and nodal extension. The recommended treatment dose is 45 Gy in the anal canal, the mesorectum, para-rectal lymph nodes, and inguinal lymph nodes. An additional dose of 15 to 20 Gy is delivered in the initial tumour for good responders. Salvage surgery is necessary in case of poor response. The organs at risk to be considered are bladder, femur heads, small intestine and vulva. The objective of this work is to summarize the epidemiological and radio-anatomic and prognostic characteristics of this tumour. The conformal radiotherapy technique is illustrated by a case report.

  12. Root Canal Filling after Revascularization/Revitalization.

    Science.gov (United States)

    Plascencia, Hugo; Cruz, Álvaro; Díaz, Mariana; Jiménez, Ana Laura; Solís, Rodrigo; Bernal, Cesar

    Revascularization/revitalization therapy is considered an alternative procedure for management of teeth with an immature apex and necrotic pulp, mainly when root development is interrupted in the early phases of formation. However, this clinical treatment protocol should be considered a permanent procedure? A maxillary central incisor with a previous and successful RR treatment was intentionally filled with a biocompatible material with the periapical tissues due to the patient's lack of adherence to the follow-up protocol. The 20-month follow-up showed absence of clinical, radiological and tomographic signs and symptoms of an endodontic re-infection. This case demonstrates that once the increased thickening of the canal walls, incrementing the root length, apical closure and the total resolution of the apical lesion are observed, the main canal of a previously treated tooth with an RR procedure can be filled.

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    In a consecutive series of minor surgical specimens from the anal canal, neuronal hyperplasia was found in nine of 56 haemorrhoidectomy specimens and in four of 23 fibrous polyps. In an additional series of 14 resections of the anal canal, neuronal hyperplasia was present in six cases, of which...... five showed haemorrhoids. In all cases, neuronal hyperplasia was located in the submucosa beneath squamous epithelium and extended over an area from 5 to 12 mm. Immunohistochemically, the foci of hyperplasia were found to consist of both neuronal and Schwann cell components. Staining for vasoactive...... intestinal peptide, neuropeptide Y and calcitonin gene related peptide, did not demonstrate any increased terminal density. It is suggested that anal neuronal hyperplasia in these cases represents an acquired lesion due to local mechanical influence....

  15. The shape of the human lumbar vertebral canal A forma do canal vertebral lombar humano

    1996-09-01

    Full Text Available Literature on the anatomy of the human vertebral column characterizes the shape of the lumbar vertebral canal as triangular. The purpose of the present study was to determine the precise shape of the lumbar vertebral canal. Ten lumbar vertebral columns of adult male cadavers were dissected. Two transverse sections were performed in the third lumbar vertebra. One section was performed at the level of the lower border of the ligamenta flava, and the other section was performed at the level of the pedicles. The shape of the lumbar vertebral canal at the level of the pedicles tends to be oval or circular, whereas the shape of the lumbar vertebral canal at the level of the lower border of the ligamenta flava is triangular. Thus, the shape of the human lumbar vertebral canal is not exclusively triangular, as reported in the literature. It is related to the level of the transversal section performed on the lumbar vertebra. This finding should be taken into consideration among factors involved in the spread of solutions introduced into the epidural space.A literatura sobre a anatomia da coluna vertebral descreve como sendo triangular o formato do canal vertebral na região lombar. O objetivo deste estudo é determinar a real forma do canal da coluna vertebral lombar.Dez colunas vertebrais de cadáveres de homens adultos foram dissecadas. Dois cortes transversais foram executados na terceira vértebra lombar. Um corte foi feito no nível das bordas inferiores de dois ligamentos amarelos vizinhos e o outro corte foi transversal, no nível dos pedículos. A forma do canal vertebral variou: no nível dos pedículos ela tende a ser oval ou circular e junto às bordas inferiores dos ligamentos amarelos passa a ser triangular. Portanto, a forma do canal vertebral lombar não é somente triangular; ela depende do nível em que se faz o corte transversal da vértebra.

  18. Root canal filling using Resilon: a review.

    LENUS (Irish Health Repository)

    Shanahan, D J

    2011-07-01

    Root canal treatment is achieved by chemo-mechanical debridement of the root canal system followed by filling. The filling material \\'entombs\\' residual bacteria and acts as a barrier which prevents the entrance of oral microorganisms and reinfection of the root canal system through microleakage. However, filling with contemporary root filling materials such as gutta-percha offers limited long-term resistance to microorganisms; as a result other materials such as Resilon have been investigated as alternatives. The aim of this review was to analyse the literature to consider whether Resilon is a suitable root canal filling material. A MEDLINE and Cochrane library search including various keyword searches identified several papers which investigated or discussed Resilon or RealSeal\\/Epiphany. Analysis of the literature demonstrated that the bulk of the literature is in vitro in nature, based largely on leakage-type studies, and demonstrates a wide variety of methodologies with conflicting findings; as a result meaningful conclusions are difficult. Within the limit of these in vitro studies Resilon appears to perform adequately in comparison to gutta-percha, however, as a result of the questionable merit of such studies, it cannot presently be considered an evidence-based alternative to the current gold standard gutta-percha. It is imperative that before Resilon is considered as a replacement material, a better understanding of the physical properties of the resin sealer and the reality of the adhesive \\'monoblock\\' are elucidated. The literature also demonstrates a paucity of quality long-term clinical outcome studies which will need to be addressed before firm conclusions can be reached.

    Abnormalities of the floor of the carotid canal have been studied in 538 skulls. These abnormalities range from a fissure to total absence of the floor. This variation may be caused by abnormalities of the internal carotid artery or deficiencies in ossification of the skull base. CT suggests that these changes should be taken into account by surgeons working on the skull base. (orig.) With 4 figs., 8 refs.

    The mandibular canal must be considered carefully during the surgical treatment, especially surgical extraction of the impacted tooth and intraosseous implant, because it contains the important inferior alveolar nerve and vessels. The author investigated the curvature of the mandibular canal and its relation to the mandibular molars and positional relation between the mental foramen and the mandibular premolars in orthopantomogram. The materials consisted of 441 orthopantomograms divided four groups; Group I consisted of 56 males and 44 females from 1 to 6 years of age, Group II consisted of 58 males and 45 females from 7 to 12 years of age, Group III consisted of 65 males and 33 females from 13 to 18 years of age, Group IV consisted of 86 males and 54 females over 19 years of age. The results were as followings; 1. The curvature of mandibular canal was 144.50 .deg. in Group II, 148.11 .deg. in Group III, 147.33 .deg. in Group IV. 2. The curvature of mandibular canal was located most frequently on the area between mandibular 1st molar and mandibular 2nd molar in Group I (42%) and on the mandibular 2nd molar area in Group II (54%), Group III (59%), Group IV (53%). 3. The position of mental foramen was most frequently below the mandibular 1st premolar in Group I (58%), between the mandibular 1st premolar and the 2nd premolar in Group II (62%), Group III (47%), and below the mandibular 2nd premolar in Group IV (58%).

    To evaluate the effect of semiconductor laser irradiation on root canal sealing after routine root canal therapy (RCT). Sixty freshly extracted single-rooted human teeth were randomly divided into six groups (n = 10). The anatomic crowns were sectioned at the cementoenamel junction and the remaining roots were prepared endodontically with conventional RCT methods. Groups A and B were irradiated with semiconductor laser at 1W for 20 seconds; Groups C and D were ultrasonically rinsed for 60 seconds as positive control groups; Groups E and F without treatment of root canal prior to RCT as negative control groups. Root canal sealing of Groups A, C and E were evaluated by measurements of apical microleakage. The teeth from Groups B, D and F were sectioned, and the micro-structures were examined with scanning electron microscopy (SEM). One way ANOVA and LSD-t test were used for statistical analysis (α = .05). The apical sealing of both the laser irradiated group and the ultrasonic irrigated group were significantly different from the control group (p0.5). SEM observation showed that most of the dentinal tubules in the laser irradiation group melted, narrowed or closed, while most of the dentinal tubules in the ultrasonic irrigation group were filled with tooth paste. The application of semiconductor laser prior to root canal obturation increases the apical sealing of the roots treated.

    Full Text Available Introduction: The purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. Methods: Sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. The teeth were sectioned at a 10 mm distance from the apex. After instrumentation, the teeth were divided into 3 groups and the canals in the three groups were obturated with lateral condensation (G1, warm vertical condensation (G2 and thermoplasticized injectable gutta percha (G3. The teeth were exposed to human saliva. Observing the turbidity of the BHI broth for a period of 63 days the number of days required for the complete contamination of root canals was recorded. The data were analyzed using descriptive statistical methods and Kruskal-Wallis test with SPSS statistical software. Results: Warm vertical condensation (G2 needed a significantly greater average time for leakage than the two other methods. No significant differences were found between lateral condensations and thermoplasticized injectable G.P techniques. Conclusion: warm vertical condensation provides a better seal against bacterial leakage than lateral condensation and obtura II method in obturating oval-canals.

Case series with chart review of patients presenting positional vertigo and positional downbeating nystagmus during a 2-year period. Outpatients' tertiary referral center for balance disorders. Eighteen patients suffering from positional vertigo and presenting positional downbeating nystagmus were treated with a maneuver based on a modification of the procedure proposed by Crevits. disappearance of positional downbeating nystagmus. Positional downbeating nystagmus was elicited unilaterally with the Dix-Hallpike maneuver in 6 cases. In 4 patients, it was triggered by both left and right Dix-Hallpike tests. In 8 patients, the positional nystagmus was elicited by a straight head-hanging maneuver. The positional nystagmus was purely downbeating in 12 patients. In the remaining, a torsional component was detected. After the treatment, only 1 patient showed positional nystagmus at 30 days. In anterior canal benign paroxysmal positional vertigo, the presence of a positional downbeating nystagmus in response to positional tests is key for diagnosis. In a significant number of patients, the affected side may not be detected because of the inconstant presence of a torsional component. Treatment with a simplified maneuver based on Crevits's technique can be considered an effective method for the treatment of anterior canal lithiasis, especially when the affected side cannot be detected clearly.

    Histologic investigations have demonstrated that root canal sealers can induce mild to severe bone resorption. Alkaline phosphatase (ALP) is a membrane-bound glycoprotein, which is one of the osteogenic differentiation markers considered to indicate the formation of new bone. The aim of this study was to investigate the effects of an epoxy resin-based sealer AH26, a zinc oxide-eugenol-based sealer Canals, and a paste sealer N2 on the expression of ALP in human osteoblastic cell line U2OS cells. Freshly mixed materials were filled in glass rings and eluted in 10 mL of culture medium for 1 day. Subsequently, various dilutions (final dilution: 1/2, 1/4, and 1/8) of these extraction media were prepared for this study. Cytotoxicity was measured by the almar blue dye assay. Gene expression of ALP was examined by using reverse transcription-polymerase chain reaction. ALP activity was further evaluated by using substrate assay. The results showed that AH26, Canals, and N2 were cytotoxic to U2OS cells in a concentration-dependent manner (P < .05). The exposure of U2OS cells to AH26 and N2 resulted in the down-regulation of ALP mRNA gene expression (P < .05). ALP activity was significantly suppressed by 3 root canal sealers (P < .05). The inhibition of ALP expression might play an important role in the pathogenesis of root canal sealer-induced periapical bone destruction. Crown Copyright 2010. Published by Elsevier Inc.

    Disputes regarding medical malpractice occur between practitioners and patients. As patients have become increasingly aware regarding medical care, an increase in the unexpected side effects of procedures has been observed, thereby leading to an increase in disputes regarding medical malpractice. In this study, we reviewed trends in precedents involving cosmetic surgery-related medical disputes, with the goal of helping to prevent unnecessary disputes in the future. We conducted a search of the judgments made in South Korean courts between 2000 and 2013 that were related to the field of plastic surgery. A total of 54 judgments were analyzed, and the selected precedents were reviewed and classified according to the kind of negligence involved. The claim amounts ranged from under 8 million KRW (6,991 USD) to 750 million KRW (629,995 USD). The most common ratio of the judgment amount to the claim amount was 20%-30%. The judgments were classified according to the following categories: violation of the duty of explanation in 17 cases (29%), violation of the duty of care in 10 cases (17%), violation of both duties in 20 cases (35%), and no violation of duty in six cases (10%). Cosmetic surgery-related suits require different approaches than general malpractice suits. The Supreme Court requires plastic surgeons to determine the type, timing, methods, and scope of their treatments when considering possible results. Therefore, practitioners should be educated on their rights and responsibilities to enable them to cope with any possible medical dispute that may arise.

    Full Text Available The increasing expansion of the Islamic financial services industry beyond its original frontiers has not only come with success stories but has also been affected by the growing preference for litigation as the mode of dispute resolution. Exorbitant legal fees and cost of sustaining protracted litigation are two major challenges that require the attention of major stakeholders in the industry. This paper examines these challenges through a Maqāṣid al-Sharī‘ah focused prism considering the importance of the sustainable dispute management framework in Islamic financial services and products. While singling out the important higher objective (maqṣad of ḥifẓ al-māl, this study argues that preservation of wealth and financial resources requires effective means of resolving increasingly diverse disputes in the Islamic financial services industry. It is further argued that an effective dispute management framework will consider the original value proposition of Islamic financial intermediation which promotes maṣlaḥah (benefits and prevents mafsadah (hardship and ḍarar (financial harm. This makes a case for the affirmative relevance, potential adoption, and systemic modernisation of Islamic dispute management mechanisms such as ṣulḥ, taḥkīm, and muḥtasib in order to fulfil the overarching objective of protection and preservation of wealth and financial resources as one of the core objectives of Sharī‘ah.

  11. Investor-State Dispute Settlement Mechanism: The Quest for a Workable Roadmap

    2013-01-01

    Full Text Available The last decade has witnessed an unprecedented increase in the use of investor-State arbitration, highlighting numerous shortcomings of the existing investor-State dispute settlement system. The legitimacy of the International Investment regime has been under severe criticism due to the growing discontent amongst the investors as well as the host States. The increased litigation has led to both the process and the outcome being questioned and has undermined the growth of harmonious relationships between foreign investors and host States. The object of this paper is to explore a workable roadmap for the investor-State dispute settlement mechanism by tracing the evolution of the existing system and by analysing the dispute settlement mechanism in major international investment agreements. Furthermore, it highlights the causes and the possible consequences of the denunciation of Bilateral Investment Treaties ('BITs' and the International Centre for Settlement of Investment Disputes ('ICSID' by host nations, which have been plagued by a myriad of investment suits. The authors suggest the need for doing away with highly protective investor-State dispute settlement mechanisms ('ISDSMs' in future investment agreements and recommend the need for designing an appellate mechanism for bringing consistency and predictability to the system.

  12. Collective Labor Disputes and Strikes in Russia: The Impact of Judicial Precedents and Enforcement

    Full Text Available The right to strike is recognized in the Constitution and the Labor Code of the Russian Federation as a means to resolve collective labor disputes. However, in Russia labor protests come up for discussion much more frequently than strikes. In recent years the number of labor protests in Russia, including various forms of work stoppage, has increased significantly compared to previous years, but the number of legally constituted collective labor disputes and strikes has remained very low. The legislation on resolution of collective labor disputes and mounting strikes is quite restrictive in Russia, and its enforcement also encourages employees to seek alternative ways to settle collective labor conflicts. There is little empirical research on the judicial implementation of these norms and its influence on the enforcement of legislation. Therefore, this paper analyses the reasoning of courts in cases on the legality of strikes, their interpretations of the law, and the impact these decisions have on the enforcement of the legislation on resolution of collective labor disputes and strikes. Our conclusion is that the courts act as another restrictive influence on the resolution of collective labor disputes and the exercise of the right to strike in Russia.

  13. Desire to Bargain and Negotiation Success: Lessons About the Need to Negotiate from Six Hydropower Disputes.

    1998-11-01

    / We investigated the notion that successful negotiations require that all parties to the dispute must have a desire to bargain. This desire is most likely to be present when the dispute exhibits ripeness and each party believes a bargained solution is the most cost-effective way to resolve differences. Structured interviews of participants in six Federal Energy Regulatory Commission hydropower licensing consultations were conducted to determine the level of need to negotiate for each party. The findings indicate that a need to negotiate is a necessary, but not sufficient, condition for success. Several factors were associated with a need to negotiate: a weak BATNA (best alternative to a negotiated agreement); a salient issue; participants' sense of efficacy; a sense of inevitability; professional roles encouraging negotiation; and disputes about facts as opposed to disputes about values. Participants' need to negotiate fluctuated throughout the process and intensified when questions were ripe: i.e., critical issues were debated or the regulatory process required action.KEY WORDS: Alternative dispute resolution; Federal licenses; Federal Energy Regulatory Commission; Instream flow; Environmental planning

    Objectives The objective of this in vitro study was to evaluate and compare the cytotoxicity of four different root canal sealers i.e. Apexit Plus (Ivoclar Vivadent), Endomethasone N (Septodont), AH-26 (Dentsply) and Pulpdent Root Canal Sealer (Pulpdent), on a mouse fibroblast cell line (L929). Materials and Methods Thirty two discs for each sealer (5 mm in diameter and 2 mm in height) were fabricated in Teflon mould. The sealer extraction was made in cell culture medium (Dulbecco's Modified Eagle's Medium, DMEM) using the ratio 1.25 cm2/mL between the surface of the sealer samples and the volume of medium in a shaker incubator. Extraction of each sealer was obtained at 24 hr, 7th day, 14th day, and one month of interval. These extracts were incubated with L929 cell line and 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) assay was done. Two-way ANOVA for interaction effects between sealer and time and Post-hoc multiple comparison using Tukey's test across all the 16 different groups were used for statistical analysis. Results Apexit Plus root canal sealer was significantly less toxic than other sealers (p Sealer showed severe to moderate toxicity. Conclusions Apexit Plus was relatively biocompatible sealer as compared to other three sealers which were cytotoxic at their initial stages, however, they became biocompatible with time.

Sixty extracted human premolars with mature apex and single root canal were randomly divided into 2 control groups and 4 experimental groups. Group CW was filled with continuous wave technique using gutta-percha and AH Plus sealer. Group GC was coated with AH-Plus sealer and then obturated with soften GuttaCore. Group GF was obturated using GuttaFlow and gutta-percha. Group EM was filled with EndoSeal MTA and gutta-percha using ultrasonic vibration. The AH-Plus, GuttaFlow, and EndoSeal were labeled with Hoechst 33342 to facilitate fluorescence. The obturated root tip was incubated with Carboxyfluorescein diacetate succinimidyl ester (CFSE)-stained E. faecalis for 14 days. CLSM was performed to evaluate the sealer distribution and bacterial leakage for the apical 1-, 2-, 3-mm specimens. Statistically significant differences were determined by 1-way ANOVA with Tukey's post-hoc test and Pearson's correlation analysis. Group EM showed the better sealer distribution score than the other groups (p  0.05). Under the conditions of this study, different root canal filling materials and methods showed different efficacy for canal distribution and bacterial leakage resistance. © Wiley Periodicals, Inc.

    The Bureau of Land Management (BLM) has been actively expanding its capacity to work cooperatively with other agencies, Tribes, the public, and other stakeholders using collaborative and alternative dispute resolution (ADR) approaches. In 1997, the BLM created the BLM’s Collaboration and Alternative Dispute Resolution Program (Collaboration/ADR Program) to centralize, strengthen, and coordinate these efforts. Specifically, the Collaboration/ADR Program is charged with developing ADR policies; ensuring that statutory and regulatory requirements are met; and providing training, resources, and direct support for collaboration and ADR in the BLM. At the request of the Collaboration/ADR Program, the Policy Analysis and Science Assistance Branch of the U.S. Geological Survey, located in the Fort Collins Science Center, conducted an online survey of BLM employees in early 2013 to address four overarching questions: What information sources and assistance resources are BLM employees currently accessing to fill their conflict/dispute resolution and collaboration needs?

    Despite advances in medical science, the causes of death can sometimes only be determined by pathologists after a complete autopsy. Few studies have investigated the importance of forensic autopsy in medically disputed cases among different levels of institutional settings. Our study aimed to analyze forensic autopsy in 120 cases of medical disputes among five levels of institutional settings between 2001 and 2012 in Wenzhou, China. The results showed an overall concordance rate of 55%. Of the 39% of clinically missed diagnosis, cardiovascular pathology comprises 55.32%, while respiratory pathology accounts for the remaining 44. 68%. Factors that increase the likelihood of missed diagnoses were private clinics, community settings, and county hospitals. These results support that autopsy remains an important tool in establishing causes of death in medically disputed case, which may directly determine or exclude the fault of medical care and therefore in helping in resolving these cases. © 2015 American Academy of Forensic Sciences.

    In recent years, the Nicaraguan government's renewed interest in constructing this interoceanic canal has once again aroused widespread concern, particularly in the global shipping industry. The project's immense ecological risks, coupled with the recent expansions of both the Panama Canal and the Suez Canal, have raised questions among scientists and experts about its viability. Whether the Nicaragua Canal is really feasible for international shipping, given its high marine pollution risks, requires the further study. This paper discusses and analyses the feasibility of the Nicaragua Canal in the context of its environmental impact and value as a shipping service. This paper aims to provide an important information reference to inform strategic decision-making among policymakers and stakeholders. Our research results indicate that the environmental complexity, economic costs and safety risks of building a new transoceanic canal are simply too high to justify the project.

    The root canal fillings are destined to seal the root canal especially in the apical areea. Invasive techniques are known which are used to assess the quality of the seal. These lead to the destruction of the probes and often no conclusion could be drawn in respect to the existence of any microleakage in the investigated areas of interest. Optical coherence tomography (OCT) is a relatively novel non-invasive imaging technique which presents potential in assessing the microleakage of the apical area in the root canal fillings with micron depth resolution. 3D reconstruction allows a complete view with obvious display of gaps in the apical root canal filling. For this study, 30 monoradicular teeth were prepared by conventional and rotative methods. Afterwards, root canal fillings were produced in each tooth. The images obtained show some microleakage in all the investigated root canal fillings. The advantages of the OCT method consist in non-invasiveness and high resolution.

    Canal of Nuck abnormalities are a rare but important cause of morbidity in girls, most often those younger than 5 years of age. The canal of Nuck, which is the female equivalent of the male processus vaginalis, is a protrusion of parietal peritoneum that extends through the inguinal canal and terminates in the labia majora. The canal typically obliterates early in life, but in some cases the canal can partially or completely fail to close, potentially resulting in a hydrocele or hernia of pelvic contents. Recognition of this entity is especially important in cases of ovarian hernia due to the risk of incarceration and torsion. We aim to increase awareness of this condition by reviewing the embryology, anatomy and diagnosis of canal of Nuck disorders with imaging findings on US, CT and MRI using several cases from a single institution.

    In June 2010 Belarus – the former Soviet country that does not feature too often in European media – attracted many headlines because of its transit dispute with Russia’s Gazprom. Presented with an ultimatum to repay its gas debt it five days or face supplies cuts, Belarus confronted Gazprom with a counter-demand to pay the debt for transit at an increased rate, threatening to reduce and potentially halt transit of gas and oil to Europe. This was not the first transit dispute between Belarus ...

    The characteristics of the infection in the root canal are analyzed, specially its development before pulpal necrosis. It is inferred that it is an ecological infection with a function: to decompose the necrosis. Inactivating the infection in the canal by the formocresol technique, calcium hidroxide or with the conventional basic treatment in Endodontics, cleaning, washing, disinfecting and, in this case, with partial obturation of the canal, it is possible to induce a reparation with osteodentine that can cover all the free extension of the canal.

  9. Mandibular second premolar with three canals: Re-treatment of a case with unusual root canal anatomy

    Directory of Open Access Journals (Sweden)

    Niranjan Desai

    2011-01-01

    Full Text Available A thorough knowledge of root canal anatomy along with the anatomical variations that may be present is essential for success of endodontic therapy. Unusual presentations in the number of the roots or the canals should be expected in every tooth. Mandibular second premolars are thought of as having a single root and canal. Studies have stated that the prevalence of three canals with three orifices in this tooth is 0.4%. The mandibular second premolar is particularly difficult to treat owing to the fact that a wide variation in the number, location and curvature of the roots and canals exist. Added to this is the fact that the access opening is restricted and location of the lingually placed orifices is difficult. This case report details the re-treatment of a mandibular second premolar with three canals and three separate orifices using the surgical microscope.

  12. Revestimientos especiales para diques y canales

    Directory of Open Access Journals (Sweden)

    Zorzi, Silvano

    1964-11-01

    Full Text Available This paper summarizes the possibilities and advantages of adopting special facings for dykes and canals, and generally for all large hydraulic works, where waterproofing is of paramount importance. Technical advances in recent years have made it possible to prefabricate many facing units used in these types of works; large slabs, made in reinforced and prestressed concrete, are flexible, and watertight. Although there are many possibilities and types of facing treatments, the one described here is outstanding. It consists of narrow slabs, highly flexible, placed transversally with respect to the canal axis. They are attached with cement mortar, and the joints are finally sealed with a special mortar, called «Emboco». In this article a description is also given of a series of projects, where facing treatments have been used, which are now successfully in service. Finally some general and simple advise is given on the best procedure to apply these facing treatments in the most effective and economic manner.En este trabajo se resumen las posibilidades y ventajas que ofrecen los revestimientos especiales de diques y taludes de canales y, en general, en todas las grandes obras hidráulicas, en que la impermeabilización es de mayor importancia al tratar de conservar los caudales iniciales o la retención de aguas embalsadas, según los casos. Los progresos de las técnicas modernas, en particular la prefabricación, han permitido este tipo de revestimientos con losas de gran longitud, extremadamente flexibles e impermeables, de hormigón armado y pretensado. Aunque son muchas las posibilidades y tipos de revestimiento, destaca el que a continuación se expone: consiste en placas o losas estrechas, de gran flexibilidad, colocadas transversalmente al eje del canal sobre tongadas de mortero de cemento, y cuyas juntas se sellan, finalmente, con un mortero especial llamado «Emboco».

  14. Root canal treatment of mandibular second premolar tooth with taurodontism

    Directory of Open Access Journals (Sweden)

    Vujašković Mirjana

    2008-01-01

    Full Text Available INTRODUCTION Taurodontism is a morphoanatomical change in the shape of a tooth. An enlarged body of a tooth with smaller than usual roots is a characteristic feature. Internal tooth anatomy correlates with this appearance, which means that a taurodontal tooth has a large pulp chamber and apically positioned furcations. This dental anomaly may be associated with different syndromes and congenital discoders. CASE OUTLINE The case report presents the patient of a rare case of taurodontism in the mandibular second premolar with chronic periodontitis. Endodontic treatment was performed after dental history and clinical examination. Special care is required in all segments of endodontic treatment of a taurodontal tooth from the identification orifice, canal exploration, determining working length, cleaning and shaping and obturation of the root canal. Precurved K-file was used for canal exploration and location of the furcation. One mesial and one distal canal with the buccal position were identified in the apical third of the root canal. The working lengths of two canals were determined by radiographic interpretation with two K-files in each canal and verified with the apex locator. During canal instrumentation, the third canal was located in the disto-lingual position. The working length of the third canal was established using the apex locator. CONCLUSION Thorough knowledge of tooth anatomy and its variations can lead to lower percentage of endodontic failure. Each clinical case involving these teeth should be investigated carefully, clinically and radiographically to detect additional root canals. High quality radiographs from different angles and proper instrumentarium improve the quality of endodontic procedure.

    Full Text Available The endodontic treatment of a mandibular molar with aberrant canal configuration can be diagnostically and clinically challenging. This case report presents the treatment of a mandibular first molar with six root canals, of which three canals were located in the mesial root and three in distal root. Third canals were found between the two main root canals. This case presents a rare anatomic configuration and points to the importance of expecting and searching for additional canals.

    2011-10-01

    This study aimed to investigate the key factors in medical disputes (arguments) among female patients after cosmetic surgery in Taiwan and to explore the correlates of medical litigation. A total of 6,888 patients (3,210 patients from two hospitals and 3,678 patients from two clinics) received cosmetic surgery from January 2001 to December 2009. The inclusion criteria specified female patients with a medical dispute. Chi-square testing and multiple logistic regression analysis were used to analyze the data. Of the 43 patients who had a medical dispute (hospitals, 0.53%; clinics, 0.73%), 9 plaintiffs eventually filed suit against their plastic surgeons. Such an outcome exhibited a decreasing annual trend. The hospitals and clinics did not differ significantly in terms of patient profiles. The Chi-square test showed that most patients with a medical dispute (p factors: marital stress (odds ratio [OR], 10.67; 95% confidence interval [CI], 1.20-94.73) and an education level below junior college (OR, 9.33; 95% CI, 1.01-86.36). The study findings suggest that the key characteristics of patients and surgeons should be taken into consideration not only in the search for ways to enhance pre- and postoperative communication but also as useful information for expert testimony in the inquisitorial law system.

  10. Past and Present Resource Disputes in the South China Sea: The Case of Reed Bank

    Directory of Open Access Journals (Sweden)

    Micah S. Muscolino

    2013-09-01

    Full Text Available In 2012, tensions flared between China and the Philippines over plans to drill for oil in the Reed Bank, a disputed shoal in the South China Sea, rekindling fears about the possibility of military conflict over the area’s energy resources. This article shows that international controversy centering on the Reed Bank’s hydrocarbon reserves initially emerged during the oil crisis of the 1970s, when the pursuit of energy resources transformed the islets into a hotly contested area. As in recent years, oil exploration by multinational corporations in conjunction with the Philippines catalyzed international disputes. Vigorous protests from China and other nations that lay claim to territories in the South China Sea prompted the Philippines to assert its own jurisdictional claims. The territorial dispute pushed claimants to the brink of military confrontation in the 1970s, yet armed conflict failed to materialize. By examining the initial round of tensions surrounding oil exploration at Reed Bank, this article situates the current international competition for the South China Sea’s energy resources in historical perspective. Analyzing past disputes and their ultimate resolution offers insights into the dynamics of present tensions, while making it possible to critically engage with arguments predicting future “resource wars” in the South China Sea.

    2000-10-01

    The central canal of the spinal cord is present at birth and becomes progressively obliterated. Cadaver studies have shown that it may persiste partially or completely. To our knowledge, this entity has not been described on MRI. We reviewed 794 MRI studies of the spinal cord, and found 12 patients (aged 14 to 65 years) who had an intramedullary cavity. The cavity was at the junction of the ventral {sup 1}/{sub 3} and dorsal {sup 2}/{sub 3} of the spinal cord, except at the level of the lumbar enlargement, where it was central. It was filiform in most cases, although sometimes fusiform (3 to 4 mm in diameter), and had regular contours. The cavity were thoracic in 69 % of cases. The clinical features were totally unrelated to the image, and there were no anatomical factors (Chiari malformation, dysraphism) predisposing to syringomyelia. The images were perfectly compatible with a persistent central canal, which we interpret as a variant of normal anatomy. Therefore it is important to regard these findings as normal, to avoid unnecessary treatment and follow-up. (orig.)

  13. Root canals-from concretion to patency

    Directory of Open Access Journals (Sweden)

    Chandrakar Chaman

    2015-01-01

    Full Text Available Teeth with calcification provide an endodontic treatment challenge; traumatized teeth usually develop partial or total pulpal obliteration which is characterized by apparent loss of the pulp space radiographically and a yellow discoloration of the clinical crown. Since only 7-27% of such teeth develop pulp necrosis with radiographic signs of apical periodontitis, it is difficult to decide whether to treat these teeth immediately upon detection of the pulpal obliteration or to wait until signs and symptoms of pulp and/or apical periodontitis occur. This article reviews the etiology, prevalence, classification, mechanism, diagnosis as well as treatment options for teeth with pulp obliteration and the various management approaches and treatment strategies for overcoming potential complications. A search of articles from "PubMed" and "Medline" from 1965 to present was done with the keywords dental trauma, discoloration, pathfinding instruments, pulp canal obliteration, and root canal treatment was conducted.

    Full Text Available The consumer field is widespread and often encompasses different legal fields on a single market, especially when it comes to the field of consumer protection. In fact, the consumer mostly remains a weaker party in resolving consumer disputes, especially in administrative proceedings. Traditional court proceedings do not always offer the most cost-appropriate way of resolving consumer disputes, because the damage with legal costs is disproportionate, especially in Small Claims (20 EUR. In theory, Alternative Dispute Resolution (hereinafter: ADR is considered more flexible, faster and cheaper for disputes between consumers and businesses. Insofar, Consumer ADR (hereinafter: CADR is seen as a useful tool that helps consumers realize their right of access to justice. It is argued that CADR systems provide valuable information on the needs of disputants, while preserving confidentiality, increasing consumer satisfaction, equality and grater trust. While CADR is praised in theory as an added value, in practice it still remains unrecognizable and therefore is seen as an ineffective formalism in some EU countries. It seems that consumers and businesses lack awareness of the CADR schemes and their benefits, which have effects on the efficient use of CADR in different public and private institutions. The focus of this paper is on the field of Public Administrative Law, which, through different approaches of scientific analysis, combines the main administrative aspects of CADR systems in the EU. Special attention is given to different administrative barriers in the development of various CADR schemes, which cause the formation of administrative dilemmas in some Member states. The new EU legal regulation on Consumer ADR, Online Dispute Resolution (ODR and EU Administrative law have set flexible rules and principles that would assure the quality of dispute resolution between EU entities with private or public interests.

    Full Text Available Aim: To assess the effects of three root canal preparation techniques on canal volume and surface area using three-dimensionally reconstructed root canals in extracted human maxillary molars. Materials and Methods: Thirty extracted Human Maxillary Molars having three separate roots and similar root shape were randomly selected from a pool of extracted teeth for this study and stored in normal saline solution until used. A computed tomography scanner (Philips Brilliance CT 64-slice was used to analyze root canals in extracted maxillary molars. Specimens were scanned before and after canals were prepared using stainless steel K-Files, Ni-Ti rotary ProTaper and rotary SafeSiders instruments. Differences in dentin volume removed, the surface area, the proportion of unchanged area and canal transportation were calculated using specially developed software. Results: Instrumentation of canals increased volume and surface area. Statistical analysis found a statistically significant difference among the 3 groups in total change in volume (P = 0.001 and total change in surface area (P = 0.13. Significant differences were found when testing both groups with group III (SafeSiders. Significant differences in change of volume were noted when grouping was made with respect to canal type (in MB and DB (P < 0.05. Conclusion: The current study used computed tomography, an innovative and non destructive technique, to illustrate changes in canal geometry. Overall, there were few statistically significant differences between the three instrumentation techniques used. SafeSiders stainless steel 40/0.02 instruments exhibit a greater cutting efficiency on dentin than K-Files and ProTaper. CT is a new and valuable tool to study root canal geometry and changes after preparation in great details. Further studies with 3D-techniques are required to fully understand the biomechanical aspects of root canal preparation.

  17. Endodontic management of mandibular canine with two canals

    2013-01-01

    Full Text Available Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment procedures. Many investigators have reported the anatomical variations associated with mandibular canines. Mandibular canines are recognized as usually having one root and one root canal in most cases. This case report describes a clinical case of mandibular canine with two canals. Human mandibular canines do not present internal anatomy as simple as could be expected; there are such canines with a single root and two canals, two roots or fused roots. The existence of mandibular canines with more than one root canal is a fact that clinicians ought to keep in mind, in order to avoid failure during endodontic treatment. In spite of the low incidence of lower canines with one root and two canals, this possibility cannot be forgotten, inasmuch as the presence of a second canal in these teeth leads to difficulties in endodontic treatment. The precise knowledge of the dental endocanalicular system′s anatomy is essential in the success of the root canal therapy, because the failure to detect the accessories canals and the incomplete radicular obturation leads to the infection of the periapical space, which will ultimately result in the loss of the tooth.

    To evaluate the current technical quality of root canal treatment (RCT) in Taiwan. A total of 1085 RCT cases, randomly selected from a large sample and representative of the Taiwanese population from April to September 2000, were evaluated by eight endodontic specialists. The qualitative evaluation of RCT cases was based on two variables: length of the root filling and density of the obturation. A root canal with both adequate filling length (the apical termination of the root filling within 2 mm of the radiographic apex) and complete obturation (no lateral or apical canal lumen visible in the apical one-third of the root canal) was defined as having good-quality endodontic work (GQEW). A tooth was defined as having a GQEW when all its canals were categorized as GQEW. From a total of 1867 root canals, overfilling occurred in 235 (12.6%), adequate filling length in 1152 (61.7%), underfilling in 466 (25.0%) and no filling in 12 (0.6%). Of the 1867 root canals, 710 (38.0%) demonstrated complete obturation and 1157 (62%) demonstrated incomplete obturation. GQEW was found in 650 (34.8%) root canals and 329 (30.3%) teeth. The percentage of teeth with GQEW in hospital cases (38.1%) was significantly greater (P RCT in Taiwan were either of inadequate filling length or sealing density.

    2006-01-01

    To clarify which part of the median nerve is the most compressed and to compare carpal canal pressure with the latency of the sensory nerve potential and the duration of symptoms. Fifteen patients with idiopathic carpal tunnel syndrome were studied using a pressure guidewire system to record canal pressure. The wire was introduced from the distal end of the carpal canal to 2 cm proximal to the distal wrist crease (DWC) and then retracted in 5-mm increments using an image intensifier to guide the progress. A nerve conduction study was performed, and all patients were asked how long the symptoms lasted. Carpal canal pressure was significantly higher 5 to 15 mm distal to the DWC. The most compressed point was 10 mm distal to the DWC, with a pressure of 44.9 +/- 26.4 mm Hg. The correlation coefficient between the highest canal pressure and the latency was 0.393 and between highest canal pressure and duration of symptoms was 0.402. Our study showed that the most compressed part of the median nerve in the carpal canal is 10 mm distal to the DWC. The carpal canal pressure was related to the latency and to the duration of symptoms.

    The lateral line system of teleost fishes consists of an array of superficial and canal neuromasts (CN). Number and distribution of neuromasts and the morphology of the lateral line canals vary across species. We investigated the morphology of the lateral line system in four diurnal European cyprinids, the limnophilic bitterling (Rhodeus sericeus), the indifferent gudgeon (Gobio gobio), and ide (Leuciscus idus), and the rheophilic minnow (Phoxinus phoxinus). All fish had lateral line canals on head and trunk. The total number of both, CN and superficial neuromasts (SN), was comparable in minnow and ide but was greater than in gudgeon and bitterling. The ratio of SNs to CNs for the head was comparable in minnow and bitterling but was greater in gudgeon and ide. The SN-to-CN ratio for the trunk was greatest in bitterling. Polarization of hair cells in CNs was in the direction of the canal. Polarization of hair cells in SNs depended on body area. In cephalic SNs, hair cell polarization was dorso-ventral or rostro-caudal. In trunk SNs, it was rostro-caudal on lateral line scales and dorso-ventral on other trunk scales. On the caudal fin, hair cell polarization was rostro-caudal. The data show that, in the four species studied here, number, distribution, and orientation of CNs and SNs cannot be unequivocally related to habitat. Copyright © 2013 Wiley Periodicals, Inc.

  5. Application of Environmental Conflict Resolution to Public Interest Issues in Water Disputes

    Directory of Open Access Journals (Sweden)

    Michael Jeffrey QC

    2011-10-01

    Full Text Available This article examines the role of environmental conflict resolution (ECR in the public interest issues of water disputes. The article endeavours to  illustrate the strengths and weaknesses of a range of alternative dispute resolution (ADR and negotiation approaches in the context of decision-making. Although many embrace ECR as the cheaper and more effective alternative to more formalistic and entrenched judicial processes before courts of law and quasi-judicial tribunals, the authors argue that there is an urgent need for a more critical, contextual and issue-oriented approach. In particular, the article highlights the significant difficulties associated with representing the full range of stakeholders who should be involved in an ADR process, and the lack of transparency and procedural safeguards associated with ADR in complex public interest disputes. The strength of ADR in smaller project-specific disputes involving a very limited number of stakeholders is well understood. The authors argue that ADR may have a significant role in scoping the issues and associated research as well as facilitating agreement on procedural aspects of large, complex public interest water disputes. However, ADR has severe limitations as a decision-making process. For example, water conflicts necessarily involve the concept of sustainability that in turn touches on a complex maze of social, political, economic and ecological values. The probability of reaching a mediated settlement in such a context is severely curtailed. A preferable approach may be one that is entirely transparent, capable of being both monitored and enforced, and is binding on all stakeholders whether or not they are parties to the mediation.

  6. Traditional and contemporary techniques for optimizing root canal irrigation.

    Holliday, Richard; Alani, Aws

    2014-01-01

    Canal irrigation during root canal treatment is an important component of chemo-mechanical debridement of the root canal system. Traditional syringe irrigation can be enhanced by activating the irrigant to provide superior cleaning properties. This activation can be achieved by simple modifications in current technique or by contemporary automated devices. Novel techniques are also being developed, such as the Self-adjusting File (Re-Dent-Nova, Ra'anana, Israel), Ozone (Healozone, Dental Ozone, London, UK), Photoactivated Disinfection and Ultraviolet Light Disinfection. This paper reviews the techniques available to enhance traditional syringe irrigation, contemporary irrigation devices and novel techniques, citing their evidence base, advantages and disadvantages. Recent advances in irrigation techniques and canal disinfection and debridement are relevant to practitioners carrying out root canal treatment.

  7. Hydrology and environmental aspects of Erie Canal (1817-99)

    1976-01-01

    As the first major water project in the United States, the old Erie Canal provides an example of the hydrological and environmental consequences of water development. The available record shows that the project aroused environmental fears that the canal might be impaired by the adverse hydrologic effects of land development induced by the canal. Water requirements proved greater than anticipated, and problems of floods and hydraulic inefficiencies beset navigation throughout its history. The Erie Canal proved the practicality of major hydraulic works to the extent that operations and maintenance could cope with the burdens of deficiencies in design. The weight of prior experience that upland streams, such as the Potomac and Mohawk Rivers, had proved unsatisfactory for dependable navigation, led to a decision to build an independent canal which freed the location from the constraints of river channels and made possible a cross-country water route directly to Lake Erie. The decision on dimensioning the canal prism--chiefly width and depth-involved balance between a fear of building too small and thus not achieving the economic potentials, and a fear of building too expensively. The constraints proved effective, and for the first part of its history the revenues collected were sufficient to repay all costs. So great was the economic advantage of the canal that the rising trend in traffic soon induced an enlargement of the canal cross section, based upon a new but riskier objective-build as large as the projected trend in toll revenues would finance. The increased revenues did not materialize. Water supplies were a primary concern for both the planners and the operators of the canal. Water required for lockage, although the most obvious to the planners, proved to be a relatively minor item compared with the amounts of water that were required to compensate for leakage through the bed and banks of the canal. Leakage amounted to about 8 inches of depth per day. The total

    2014-09-01

    Full Text Available Background: Successful endodontic treatment requires effective biomechanical preparation of the root canals and three-dimensional obturation of the root canal system. This can be achieved only by knowing and identifying the variations in the root canal system of the endodontically treated teeth. The Aim: The aim of this article is to present cases of endodontic treatment of maxillary first premolar with three root canals – different types. Material and Methods: Five clinical cases of successful endodontic treatment of patients with maxillary first premolar and three root canals are described. Result and Discussion: It is noted that good endodontic practice requires good knowledge of dental anatomy and possible variations, accurate X-ray images, as well as use of magnifying equipment. Conclusion: Knowledge of dental anatomy is fundamental for good endodontic practice.

    Superior canal dehiscence syndrome (SCDS) is an increasingly recognized cause of hearing loss and vestibular symptoms, but the etiology of this condition remains unknown. To describe 7 cases of SCDS across 3 families. This retrospective case series included 7 patients from 3 different families treated at a neurotology clinic at a tertiary academic medical center from 2010 to 2014. Patients were referred by other otolaryngologists or were self-referred. Each patient demonstrated unilateral or bilateral SCDS or near dehiscence. Clinical evaluation involved body mass index calculation, audiometry, cervical vestibular evoked myogenic potential testing, electrocochleography, and multiplanar computed tomographic (CT) scan of the temporal bones. Zygosity testing was performed on twin siblings. The diagnosis of SCDS was made if bone was absent over the superior semicircular canal on 2 consecutive CT images, in addition to 1 physiologic sign consistent with labyrinthine dehiscence. Near dehiscence was defined as absent bone on only 1 CT image but with symptoms and at least 1 physiologic sign of labyrinthine dehiscence. A total of 7 patients (5 female and 2 male; age range, 8-49 years) from 3 families underwent evaluation. Family A consisted of 3 adult first-degree relatives, of whom 2 were diagnosed with SCDS and 1 with near dehiscence. Family B included a mother and her child, both of whom were diagnosed with unilateral SCDS. Family C consisted of adult monozygotic twins, each of whom was diagnosed with unilateral SCDS. For all cases, dehiscence was located at the arcuate eminence. Obesity alone did not explain the occurrence of SCDS because 5 of the 7 cases had a body mass index (calculated as weight in kilograms divided by height in meters squared) less than 30.0. Superior canal dehiscence syndrome is a rare, often unrecognized condition. This report of 3 multiplex families with SCDS provides evidence in support of a potential genetic contribution to the etiology

    To study the effect of the left bacteria on the root canal therapy. 50 single-rooted teeth with chronic apical periodontitis were divided into two groups, one was instrumented with step-back technique and 2.5%NaOCl ultrasonic irrigation for 3 min, then filled with Thermafil. Samples were taken after instrumentation to culture. The other was treated with traditional RCT at three visits. In 24 months the apical radiolucency were greatly reduced in all cases. There weren't significant relationship among the postoperative pain and the left bacteria, the degree of the obturation or the pre-operative symptoms (P > 0.05). The effect of left bacteria in root canal filled with Thermafil wasn't observed.

    The toxic wastes that were dumped in the 1950s at Love Canal in New York and then seeped into groundwater and the basements of local residents in the late 1970s are to be finally incinerated, according to a plan recently announced by the US Environmental Protection Agency (EPA). This last, five-year stage in the cleanup will entail the building of an incinerator for burning 35,000 cubic yards of dioxin-contaminated sediment dredged from creeks and sewers in the area at a cost of up to $31 million. The incinerated residue - which will be purified of detectable levels of dioxin, says EPA - will be returned to the site and spread several feet deep.

    A large portion of the seismic noise spectrum is dominated by water wave energy coupled into the solid Earth. Distinct mechanisms of water wave induced ground motions are distinguished by their spectral content. For example, cultural noise is generally Panama Canal there is an additional source of long-period noise generated by standing water waves, seiches, induced by disturbances such as passing ships and wind pressure. We compare seismic waveforms to water level records and relate these observations to changes in local tilt and gravity due to an oscillating seiche. The methods and observations discussed in this paper provide a first step toward quantifying the impact of water inundation as recorded by seismometers. This type of quantified understanding of water inundation will help in future estimates of similar phenomena such as the seismic observations of tsunami impact.

    Full Text Available Economic actors are the main trade player in the World Trade Organization, although, the relation between WTO and economic actor is built by trade regulation that is negotiated among the WTO Members. Nothing in the WTO regulates economic actors to involve directly in the WTO, especially in the WTO dispute settlement system. Nevertheless, the debate amongst experts regarding the involvement of economic actors in the WTO dispute settlement system is unavoidable. This article therefore discusses the possibility of the involvement of economic actors in the WTO dispute settlement system, whether there is legal and political point of views

  15. MANAGEMENT OF LUMBAR SPINAL CANAL STENOSIS

    2016-06-01

    Full Text Available BACKGROUND Spinal stenosis is one of the most common conditions in the elderly. It is defined as a narrowing of the spinal canal. The term stenosis is derived from the Greek word for narrow, which is “Stenos”. The first description of this condition is attributed to Antoine portal in 1803. Verbiest is credited with coining the term spinal stenosis and the associated narrowing of the spinal canal as its potential cause. [1-10] Kirkaldy–Willis subsequently described the degenerative cascade in the lumbar spine as the cause for the altered anatomy and pathophysiology in spinal stenosis. [11-15] If compression does not occur, the canal should be described as narrow but not stenotic. Some studies defined lumbar spinal stenosis as a “narrowing of the osteoligamentous vertebral canal and/or the intervertebral foramina causing compression of the thecal sac and/or the caudal nerve roots; at a single vertebral level, narrowing may affect the whole canal or part of it” (Postacchini 1983. This definition distinguished between disc herniation and stenosis. [16] . The most common type of spinal stenosis is caused by degenerative arthritis of the spine. Hypertrophy and ossification of the posterior longitudinal ligament which usually are confined to the cervical spine, and diffuse idiopathic skeletal hyperostosis (DISH syndrome also may result in an acquired form of spinal stenosis. Congenital forms caused by disorders such as achondroplasia and dysplastic spondylolisthesis are much less common. Congenital spinal stenosis usually is central and is evident or imaging studies. Idiopathic congenital narrowing usually involves the anteroposterior dimension of the canal secondary to short pedicles; the patient otherwise is normal. In contrast, in achondroplasia, the canal is narrowed in the anteroposterior plane owing to shortened pedicles and in lateral dimension because of diminished interpedicular distance. Acquired forms of spinal stenosis usually are

    Lumbar canal stenosis (LCS) is a degenerative disease involving the lumbar vertebrae, discs, and ligamentum flavum that result in neurological deficit to some extent. The natural history of symptoms of LCS is highly important because they do not necessarily worsen with progressive degeneration. Therefore, a observation therapy is adopted for the treatment of this condition. Although invasive treatment is required for some patients, surgery cannot be performed solely on the basis of radiological findings and careful evaluation of neurological symptoms is necessary. In the event that spinal surgery is required, it is important to minimize degree of invasiveness; various devices and operative approaches and methods have been developed to this end. Our strategy for the surgical treatment of LCS involves microscopic decompression via a posterior approach. In our method, modified bilateral decompression via the splitting of the spinous process using an ultrasonic bone curette (SONOPET), and the results of this approach have been excellent. Our method is less invasive, facilitates the preservation of the paraspinal muscle, and represents a useful approach to posterior spinal elements. Our findings indicate that this method involves less muscle damage as compared to other methods. LCS should be differentiated from conditions other than those involving the spinal canal such as foraminal stenosis and far-out syndrome, piriformis syndrome, and tarsal tunnel syndrome. The incidence of these conditions is higher than appreciated and they present with neurological deficits similar to observed in LCS. Here, we report our criteria of operative indications for surger and the procedures that we developed for the treatment of LCS, based on a review of the available literature.

    Root canal preparation is an important process in endodontic therapy. Nickel-titanium (NiTi) rotary file system can be used in single length technique (simultaneous technique) without early coronal enlargement, as well as in crown-down method. The purpose of this in vitro study was to compare single length with crown-down methods' shaping ability using Mtwo NiTi files. Fifteen acrylic-resin blocks containing simulated canals were divided into two experimental groups. In group A, single length technique was used and in group B root canals were prepared by crown-down technique. Pre- and post-preparation canals were photographed in a standardized manner and were superimposed. The inner and outer walls of canal curvature were evaluated at three points (apical, middle and coronal) to determine the greatest change. The data was statistically analyzed using the Student t-test by Statistical Analysis System (SAS) software. Statistical analysis revealed that in group B, dentine was equally removed within the canal coronal to the curvature, whereas in group A, the inner wall was predominantly removed (Plength method and crown-down technique using Mtwo for preparation of apical and middle portion of canal curvature.

    Complications that arise during endodontic procedures pose serious threats to the long-term integrity and health of the tooth. Potential complexities of root canals include residual pulpal tissue, cracks, mesial-buccal 2 and accessory canals. In the case of a failed root canal, a successful apicoectomy can be jeopardized by isthmuses, accessory canals, and root microfracture. Confirming diagnosis using a small imaging probe would allow proper treatment and prevent retreatment of endodontic procedures. An ultrathin and flexible laser scanning endoscope of 1.2 to 1.6mm outer diameter was used in vitro to image extracted teeth with varied root configurations. Teeth were opened using a conventional bur and high speed drill. Imaging within the opened access cavity clarified the location of the roots where canal filing would initiate. Although radiographs are commonly used to determine the root canal size, position, and shape, the limited 2D image perspective leaves ambiguity that could be clarified if used in conjunction with a direct visual imaging tool. Direct visualization may avoid difficulties in locating the root canal and reduce the number of radiographs needed. A transillumination imaging device with the separated illumination and light collection functions rendered cracks visible in the prepared teeth that were otherwise indiscernible using reflected visible light. Our work demonstrates that a small diameter endoscope with high spatial resolution may significantly increase the efficiency and success of endodontic procedures.

  19. Management of middle mesial canal in mandibular second molar

    Directory of Open Access Journals (Sweden)

    J V Karunakaran

    2012-01-01

    Full Text Available The primary objective of endodontic therapy is to achieve a three-dimensional obturation of the root canal space after adequate preparation of the canal space to remove the tissue debris, microorganisms, and their byproducts. Anatomical variations have frequently been encountered in endodontic practice and have to be adequately managed by the clinician. Missed roots and canals are a major reason for failure of therapy. Technological advances have given the clinician ample opportunity to identify and treat these aberrations successfully. The present report describes a left mandibular second permanent molar requiring root canal treatment, found to have three separate canals in the mesial root. This case demonstrates a rare anatomical configuration and emphasizes the need for the clinician to be aware of and look out for such variations and use adequate diagnostic methodologies prior to and during therapy to detect such variations. The possibility of additional canals, whenever in doubt, should be explored with the assistance of technologies such as those of magnification and illumination and various diagnostic aids. Operator experience has also shown to be a key factor in negotiation and management of these aberrant canal configurations.

    Compression neuropathy of the ulnar nerve at the Guyon canal is commonly seen by hand surgeons. Different anatomical variations of structures related to the Guyon canal have been reported in the literature. A thorough knowledge of the normal contents and possible variations is essential during surgery and exploration. To review the recognized anatomical variations within and around the Guyon canal. This study is a narrative review in which relevant papers, clinical studies, and anatomical studies were selected by searching electronic databases (PubMed and EMBASE). Extensive manual review of references of the included studies was performed. We also describe a case report of an aberrant muscle crossing the Guyon canal. This study identified several variations in the anatomical structures of the Guyon canal reported in the literature. Variations of the ulnar nerve involved its course, branching pattern, deep motor branch, superficial sensory branch, dorsal cutaneous branch, and the communication with the median nerve. Ulnar artery variations involved its course, branching pattern, the superficial ulnar artery, and the dorsal perforating artery. Aberrant muscles crossing the Guyon canal were found to originate from the antebrachial fascia, pisiform bone, flexor retinaculum, the tendon of palmaris longus, flexor carpi ulnaris, or flexor carpi radialis; these muscles usually fuse with the hypothenar group. The diverse variations of the contents of the Guyon canal were adequately described in the literature. Taking these variations into consideration is important in preventing clinical misinterpretation and avoiding potential surgical complications.

    Determining root canal length is a crucial step in success of root canal treatment. Root canal length is commonly estimated based on pre-operation intraoral radiography. 2D depiction of a 3D object is the primary source of error in this approach. Techniques based on impedance measurement are more accurate than radiographic approaches, but do not offer a method for depicting the shape of canal. In this study, we investigated a stererotactic approach for modeling and measurement of root canal of human dentition. A weakly perspective model approximated the projectional geometry. A series of computer-simulated objects was used to test accuracy of this model as the first step. The, to assess the clinical viability of such an approach, endodontic files inserted in the root canal phantoms were fixed on an adjustable platform between a radiographic cone and an image receptor. Parameters of projection matrix were computed based on the relative positions of image receptors, focal spot, and test objects. Rotating the specimen platform from 0 to 980 degrees at 5-degree intervals set relative angulations for stereo images. Root canal is defined as the intersection of two surfaces defined by each projection. Computation of error for length measurement indicates that for angulations greater than 40 degrees the error is within clinically acceptable ranges.

    The aim of this radiographic investigation was to study procedural errors encounterd in root canal treatment in a Jordanian population as evidenced using periapical radiographs A total of 2380 periapical radiographs including 3178 endodontically treated teeth were assessed in respect of the quality of endodontic treatment. The results indicated that the prevalence of endodontically treated teeth in the maxilla was higher than that in the mandible ( P endodontic treatment, and the maxillary second molars have the lowest prevalence of endodontic treatment. In respect of the quality of endodontic treatment, 30.2% of endodontically treated teeth exhibited an ideal length of root canal filling, 23.64% of the evaluated teeth were mummified, 37.45% of the teeth have short root canal fillings, 6.25% were overfilled, 1.35% were with preparations which deviated from the line of the root canal and 1.10% of the evaluated teeth have perforations of the root walls or the floor of the pulp chamber. It is concluded that the Maxillary teeth were found to be endodontically treated more frequently than the mandibular teeth, anterior teeth were found to be endodontically treated more than premolar and molar teeth, maxillary central incisors have the highest prevalence of endodontic treatment whilst the maxillary second molars have the lowest prevalence. The quality of endodontic treatment was disappointing. Therefore, emphasis on continuing education and post graduate courses in endodontics must be a priority in Jordan.

    Background The aim of the present study was to compare in vitro the antimicrobial activity of different root canal sealers against Enterococcus faecalis, prior and subsequent to setting. Material and Methods Agar diffusion test (ADT) was used for evaluating the antibacterial activity of non-set sealer while the direct contact test (DCT) was used for after setting. Results ADT: Except for TotalFill BC Sealer all the others sealers tested showed antibacterial activity. BioRoot™RCS, MTA Fillapex and Sealapex Root Canal Sealer showed the lowest antibacterial activity, a significant increase in antibacterial effect for both Pulp Canal Sealer™ and AH plus sealers were found. Significantly higher were the mean diameters of the bacterial inhibition zone by both EasySeal or N2 sealers. DCT: AH plus and Sealapex Root Canal Sealer doesn’t show any bactericidal effect after 6 min of contact. After 15 and 60 min of contact a significant increment for AH plus and for Sealapex Root Canal Sealer of the bactericidal effect was found. Significantly much higher was the antibacterial effect of Sealapex Root Canal Sealer compare to that observed for AH plus. BioRootTMRCS, MTA Fillapex, Pulp Canal Sealer™ and N2 showed at least means of the number of colonies formed in milliliter after 6 min of contact. Except for N2, a significant increase in bactericidal effect after 15 and 60 min for the other compared sealers (BioRootTMRCS, MTA Fillapex and Pulp Canal Sealer™). Conclusions For every contact times considered, both TotalFill BC Sealer and EasySeal were bactericidal against E. faecalis and killed all bacteria. Key words:Agar diffusion test, antibacterial activity, direct contact test, Enterococcus faecalis, root canal sealer. PMID:28638549

    Full Text Available Before the formation of the Central American Isthmus, there was a Central American Peninsula. Here we show that southern Central America existed as a peninsula as early as 19 Ma, based on new lithostratigraphic, biostratigraphic and strontium chemostratigraphic analyses of the formations exposed along the Gaillard Cut of the Panama Canal. Land mammals found in the Miocene Cucaracha Formation have similar body sizes to conspecific taxa in North America, indicating that there existed a terrestrial connection with North America that allowed gene flow between populations during this time. How long did this peninsula last? The answer hinges on the outcome of a stratigraphic dispute: To wit, is the terrestrial Cucaracha Formation older or younger than the marine La Boca Formation? Previous stratigraphic studies of the Panama Canal Basin have suggested that the Cucaracha Formation lies stratigraphically between the shallow-marine Culebra Formation and the shallow-to-upper-bathyal La Boca Formation, the latter containing the Emperador Limestone.

    The purpose of this study was to analyze the quality of obturation affecting the long-term results of root canal therapy (RCT) by radiographic evaluation. Teeth of RCT for 2 or more than 2 years were chosen, and periapical radiographs were taken with paralleling technique. The patients' age, gender, etiology, the time of therapy were recorded. The current apical periodontal status of these endodontically treated teeth were examined and recorded. The data were subjected to univariate and multivariate analysis with SPSS13.0 software package. This study investigated 215 cases with 376 endodontically treated teeth. The success rate was 54.79%. If counted by root canal, there were 513 root canals, the success rate was 61.4%. The quality of obturation including obturation position and obturation density affected significantly the results of root canal therapy (Pobturation position for successful treated canals was 0.5-2mm from the radiographic apex. The success rate was higher for a good obturation density, especially in the apical third. No statistically significant differences were found based on gender, age and obturation time. The quality of root canal obturation significantly affected the long-term results of root canal therapy.

    Full Text Available Introduction: Cleanliness of the canal space is the ultimate goal of its preparation. Nevertheless, some portion of the canal walls are left un-instrumented during preparation. Therefore, the aim of this ex vivo study was to evaluate the cleanliness of un-instrumented canal walls after root canal preparation for the presence or absence of debris and smear layer. Materials and Methods: A total of 24 single-rooted extracted teeth were prepared with the crown-down technique using Protaper universal rotary file system. Micro-computed tomography (micro-CT was used to scan the specimens before and after instrumentation. The un-instrumented area was measured and localized. The roots were split longitudinally and then subjected to scanning electron microscopy (SEM. The presence of debris and smear layer in the instrumented and un-instrumented areas of the canal were evaluated by analysing the SEM images with a five-score evaluation system based on the reference photographs. Results: High levels of root canal cleanliness (≤ score 2 were found for the instrumented areas were detected (P = 0.003. Conclusions: Under the condition of this study, un-instrumented areas of the canal were less clean in comparison to instrumented portion.

    Full Text Available Between 1997 and 2003, in a series of relevant cases, the Electoral Court of the Federal Judicial Branch (ECFJB increased its capacity to adjudicate intraparty disputes. This paper explains how the ECFJB, without a supporting legislation, was able to establish a direct and far reaching control over intraparty disputes such as the election of party leaders, the selection of candidates, or the punishment of party members. Following a strategic behavior approach, I will provide empirical evidence to prove that there was a negative correlation between the level of judicial control over the parties’ internal life, on the one hand, and the vulnerability of the ECFJB from the legislature and party leaders, on the other.

    2008-03-01

    Qualitative case study findings are presented. We examined whether public participation in a hazardous waste dispute manifested in ways consistent with theories of social power; particularly whether participatory processes or participants' experiences of them were consistent with the three-dimensional view of power (Gaventa, Power and powerlessness: quiescence and rebellion in an appalacian valley, 1980; Lukes, Power: A radical view, 1974; Parenti, Power and the powerless, 1978). Findings from four data sources collected over 3 years revealed that participatory processes manifested in ways consistent with theories of power, and participants' experiences reflected this. Results illustrated how participation was limited and how citizen influence could be manipulated via control of resources, barriers to participation, agenda setting, and shaping conceptions about what participation was possible. Implications for community research and policy related to participation in hazardous waste disputes are discussed.

    Recalcitrant disputes among health care providers and patients or their families may signal deep cultural differences about what interventions are needed or about clinicians's professional duties. These issues arose in relation to a mother's request for hymenoplasty or revirgination for her minor daughter to enable an overseas, forced marriage and protect her from an honor killing. The American College of Obstetrics and Gynecology committee recommends against members performing a hymenoplasty or other female genital cosmetic surgeries due to a lack of data concerning their safety and efficacy. A key issue in such cases is how to determine what is in the minor's best interest and the scope of health care moral or professional's duties. The Best Interests Standard can serve as a powerful moral tool for resolving cross-cultural disputes and identifying needed policy.

    Full Text Available Based on a geographical-administrative definition of the region, the theoretical assumptions of contemporary French structuralist geopolitics, cross-sectional data for 1990, 1995, 2000, 2005 and 2010 from the Updated Arctic Regional Attributes Dataset, and the technical capabilities of MS Office Excel 2010, this research (a reveals and contrasts the Arctic states’ capability constraints deriving from their longitudinal material and virtual power potential (physical potential, socio-economic potential, military potential, and symbolic potential; and (b analyses the role of this constraint in the process of preference formation in case of one specific Arctic actor, Russia, in the Arctic territorial dispute. This study confirms that Russia’s capability constraint is the lowest in the region and that the latter does not form a stable trend throughout the period studied. It also suggests the preference formation framework for Russia in the Arctic dispute based on the evolution of its polar capability constraint.

    Song, Wei; Song, Jiakun

    2012-03-01

    Light and scanning electron microscopy (SEM) were used to study the epidermal lateral line system of the Siberian sturgeon (Acipenser baerii Brandt, 1869). This system consists of mechanoreceptive neuromasts, ampullae and the electroreceptive organ. The neuromasts are located in 5 pairs of cephalic and 1 pair of trunk canals and superficially in the middle and posterior pit lines that lie dorsomedially along the top of the skull immediately adjacent to the otic ampullae field. Both canal neuromasts and pit organ superficial neuromasts have opposite polarized hair cells that are parallel along the axis of the canal and pit line, respectively. However, they differ in both size and shape and in the density and length of the hair bundles. The ampullae are confined on the head, adjacent to the neuromast lines. The morphological structure of the ampullae in the Siberian sturgeon is similar to the ampullae in elasmobranchs and other primitive fish. Nevertheless, it has a relatively large mucus-filled ampulla, and a shorter and narrower canal leading to a small opening to the outer epidermal surface. We also present new information concerning the peripheral innervation of lateral line receptors in sturgeons. The receptors of the lateral line system are innervated by 2 pairs of cranial nerves: anterior and posterior lateral line nerves. The peripheral processes of the anterior lateral line nerve form superficial ophthalmic, buccal, otic and anteroventral rami. The peripheral processes of the posterior lateral line nerve form middle, supratemporal and lateral rami. © 2012 ISZS, Blackwell Publishing and IOZ/CAS.

    2013-05-01

    A well-established doctor-patient relationship is essential for dental care. Once ­there is a legal dispute between the dentist and the patient this doctor-patient relationship has failed. Here we show for the first time how dentists experience these lawsuits. We characterise the dentist's perspectives and investigate their influence on the doctor-patient relationship. The experience of dentists who were involved in a legal dispute due to a failed dental treatment is pictured in a pilot study on the basis of narrative and problem-oriented interviews. The narrative part of the interview was analysed with the technique of narration analysis. The problem-oriented part of the interview was evaluated content-analytically. From these data a model describing the failure of a doctor-patient relationship was developed. Communicated burdens and stress were: expenditure of time, duration of the proceedings, financial burdens, limited support and the feeling of being treated unfairly. Consequences taken from the legal dispute were a more detailed documentation and an improvement in patient information. The conflict in the doctor-patient relationship is transformed to a different platform when the legal profession is involved. This contradictory constellation leads to a break in the doctor-patient relationship. Advice for other affected colleagues is: remain calm, aim at an out of court settlement, seek advice from other colleagues and request legal advice, be proactive, avoid court litigation and in the end draw conclusions from the dispute. There is a need for a higher quality of legal dental experts. A contact platform provided by the dental profession is required for interactive collegial communication. Lawsuits in cases of a conflict between the doctor and the patient are very stressful and need an active coping management but also are a chance for the development of the individual dentist and the profession. © Georg Thieme Verlag KG Stuttgart · New York.

    Force, Melissa K.

    2013-09-01

    The mechanisms and procedures for settlement of disputes arising from space debris collision damage, such as that suffered by the Russian Cosmos and US Iridium satellites in 2009, are highly political, nonbinding and unpredictable - all of which contributes to the uncertainty that increases the costs of financing and insuring those endeavors that take place in near-Earth space, especially in Low Earth Orbit. Dispute settlement mechanisms can be found in the 1967 Outer Space Treaty, which provides for consultations in cases involving potentially harmful interference with activities of States parties, and in the 1972 Liability Convention which permits but does not require States - not non-governmental entities - to pursue claims in a resolution process that is nonbinding (unless otherwise agreed.) There are soft- law mechanisms to control the growth of space debris, such as the voluntary 2008 United Nations Space Debris Mitigation Guidelines, and international law and the principles of equity and justice generally provide reparation to restore a person, State or organization to the condition which would have existed if damage had not occurred, but only if all agree to a specific tribunal or international court; even then, parties may be bound by the result only if agreed and enforcement of the award internationally remains uncertain. In all, the dispute resolution process for damage resulting from inevitable future damage from space debris collisions is highly unsatisfactory. However, the Administrative Council of the Permanent Court of Arbitration's recently adopted Optional Rules for the Arbitration of Disputes Relating to Outer Space Activities are, as of yet, untested, and this article will provide an overview of the process, explore the ways in which they fill in gaps in the previous patchwork of systems and analyze the benefits and shortcomings of the new Outer Space Optional Rules.

    Full Text Available Disinfection of the root canal system is one of the primary aims of root canal treatment. This can be achieved through the use of various antimicrobial agents in the form of irrigants and medicaments. The antimicrobial substantivity of 2% chlorhexidine gluconate, 1% povidone iodine, 2.5% hydrogen peroxide followed by 2% sodium hypochlorite, and 2% sodium hypochlorite alone as irrigants was assessed in instrumented root canals. 2% chlorhexidine showed antimicrobial substantivity lasting up to 72 h, followed by 1% povidone iodine, and 2% sodium hypochlorite. Thus 2% chlorhexidine should be used as a final rinse irrigant in endodontic treatment protocols.

    Emergency medicine is a 'high risk' specialty. Some diseases develop suddenly and progress rapidly, and sudden unexpected deaths in the emergency department (ED) may cause medical disputes. We aimed to assess discrepancies between antemortem clinical diagnoses and postmortem autopsy findings concerning emergency medicine dispute cases and to figure out the most common major missed diagnoses. Clinical files and autopsy reports were retrospectively analysed and interpreted. Discrepancies between clinical diagnoses and autopsy diagnoses were evaluated using modified Goldman classification as major and minor discrepancy. The difference between diagnosis groups was compared with Pearson χ2 test. Of the 117 cases included in this study, 71 of cases (58 class I and 13 class II diagnostic errors) were revealed as major discrepancies (60.7%). The most common major diagnoses were cardiovascular diseases (54 cases), followed by pulmonary diseases, infectious diseases and so on. The difference of major discrepancy between the diagnoses groups was significant (pclinical diagnoses and postmortem examinations exist in emergency medical disputes cases; acute aortic dissection and myocardial infarction are the most frequently major missed diagnoses that ED clinicians should pay special attention to in practice. This study reaffirmed the necessity and usefulness of autopsy in auditing death in EDs. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  15. J. B. S. Haldane, Ernst Mayr and the Beanbag genetics dispute.

    Rao, Veena; Nanjundiah, Vidyanand

    2011-01-01

    Starting from the early decades of the twentieth century, evolutionary biology began to acquire mathematical overtones. This took place via the development of a set of models in which the Darwinian picture of evolution was shown to be consistent with the laws of heredity discovered by Mendel. The models, which came to be elaborated over the years, define a field of study known as population genetics. Population genetics is generally looked upon as an essential component of modern evolutionary theory. This article deals with a famous dispute between J. B. S. Haldane, one of the founders of population genetics, and Ernst Mayr, a major contributor to the way we understand evolution. The philosophical undercurrents of the dispute remain relevant today. Mayr and Haldane agreed that genetics provided a broad explanatory framework for explaining how evolution took place but differed over the relevance of the mathematical models that sought to underpin that framework. The dispute began with a fundamental issue raised by Mayr in 1959: in terms of understanding evolution, did population genetics contribute anything beyond the obvious? Haldane's response came just before his death in 1964. It contained a spirited defense, not just of population genetics, but also of the motivations that lie behind mathematical modelling in biology. While the difference of opinion persisted and was not glossed over, the two continued to maintain cordial personal relations.

    2013-07-01

    Full Text Available Root canal therapy is the most effective way to treat various pulposis and periapical disease. Simple mechanical apparatus can not clean root canal thoroughly, but may affect tight filling instead. It can achieve a satisfactory cleansing effect only when it is combined with a chemical solution. Irrigation fluid for root canal should possess the properties of tissue dissolution, antimicrobial, lubrication, and removal of smear layer. So far, no solution is able to fulfill all these functions. Therefore, a combined use of multiple irrigation solutions is suggested. It can not only achieve good effect in cleaning and disinfection, also it can lower the concentration of different solutions, thus reducing the side effects. Nevertheless, some experiments proved that antagonism existed among the chemicals used for irrigations. The purpose of present article is to review the antagonistic effect among the chemicals used for irrigation when they are used together for root canal treatment.

    To analyze greater palatine canal (GPC) dimensions using cone-beam computed tomography (CBCT) images, and to evaluate the position of the greater palatine foramen (GPF) with respect to various landmarks selected in relation to dental status. This study included 150 CBCTs. Axial slices were used to determine the position and dimensions of the GPF. Sagittal slices were used to assess GPC length. Reference lines were established to evaluate the GPC diameter in sagittal and coronal slices. From the 77 GPF analyzed, 76 were located on level 2. Average posterior GPF distance was 6.59 ± 3.27 mm on right side and 7.35 ± 3.40 mm on left side. Several measurements to determine the position and dimensions of the GPF presented significant values (p ≤ 0.05). GPC length was 12.31 ± 1.96 mm on right side and 12.52 ± 2.15 mm on left side, statistically significant differences were detected between genders only on right canal (p ≤ 0.004). Sagittal and coronal reference lines presented significantly higher values for men except for the S3 (p plane and posterior nasal plane are two intraoral anatomical landmarks for the location of the GPF. Their scant variability allows accurate identification of GPFs in both dentate as well as edentulous patients.

    Preoperative radiographic assessment of the mandibular third molars is essential to prevent inferior alveolar nerve damage during extraction. The purpose of this study was to assess the reliability of panoramic signs of association between the roots of teeth and the canal, and to compare the panoramic signs with cone beam computed tomography (CBCT) findings. CBCT images of 132 impacted mandibular third molars were evaluated to determine the association of the root to the canal. The CBCT findings were compared with the corresponding panoramic images. Logistic regression analysis was used to define the diagnostic criteria of the panoramic images. Among the panoramic signs, loss of the cortical line was the most frequent radiographic sign predicting association (sensitivity: 79.31). Contact of the tooth with the canal was observed in all cases in which the loss of cortical line of the canal or darkening of the roots was found on the panoramic radiographs. Darkening of the roots and loss of the cortical line on panoramic radiographs might be highly suggestive of the risk of nerve injury.

    Root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection. RCT involves removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue through biomechanical instrumentation, and root canal obturation using a filler material to replace the space that was previously composed of dental pulp. Gutta percha (GP) is typically used as the filler material, as it is malleable...

    Endodontic therapy is often complicated and technically demanding. The aim of this study was to develop a reproducible biomimetic root canal model for pre-clinical and postgraduate endodontic training. A specific ceramic shaping technique (3D printing and slip casting of a root canal mould) was developed to reproduce canal systems with the desired shape and complexity using a microporous hydroxyapatite (HAp)-based matrix. The microstructural morphology, pore size and porosity, as well as the Vickers microhardness of the ceramic simulators (CS) were assessed and were compared with natural dentin and commercial resin blocks. The reproducibility of the root canal shapes was assessed using the Dice-Sørensen similarity index. Endodontic treatments, from refitting the access cavity to obturation, were performed on the CS. Each step was controlled by radiography. Many properties of the CS were similar to those of natural dental roots, including the mineral component (HAp), porosity (20%, porous CS), pore size (3.4 ± 2.6 μm) and hardness (120.3 ± 18.4 HV). We showed that it is possible to reproduce the radio-opacity of a tooth and variations in root canal morphology. The endodontic treatments confirmed that the CS provided good tactile sensation during instrumentation and displayed suitable radiological behaviour. This novel anatomic root canal simulator is well suited for training undergraduate and postgraduate students in endodontic procedures. © 2016 John Wiley & Sons A/S.

    2016-04-01

    Full Text Available Causality between spinal cord compression and polyneuropathy is difficult to define, especially under the circumstances that polyneuropathy can have many causes. Seven patients with spinal cord compression and electrophysiological signs of polyneuropathy were treated surgically on decompression of their spinal canal stenosis in the time from April 2010 to January 2013. Median follow up time was 9 months (2-23 months. Causes of polyneuropathy were: 1 patient with methotrexate-induced polyneuropathy, 1 endocrine-dysfunction-induced, 2 with diabetic- polyneuropathy, and 3 patients had unknown reasons. The localization of the spinal canal stenosis was also varying: 2 patients suffered of cervical spinal canal stenosis and 5 of lumbar. Decompressive surgery led to pain relieve in all patients initially. Surprisingly, also symptoms of polyneuropathy seemed to regress in all 7 patients for the first 5 months after surgery, and in 5 patients for the time of 9 months after surgery. There are two points we would like to emphasize in this short report. Since 5/7 patients with polyneuropathy and spinal canal stenosis improved clinically after surgery, surgery has a place in the treatment of such a combined pathology. Since it seems to be a possible causality between polyneuropathy of unknown origin and spinal cord stenosis, decompression of the spinal canal could also be a therapeutic step in a specific kind of polyneuropathy. Which patients could possibly have a spinal canal stenosis induced polyneuropathy remains a subject of further studies.

Material and Methods Fibroblasts (3T3, 1×105 cells per well were incubated with elutes of fresh specimens from eight root canal sealers (AH Plus, Epiphany, Endomethasone N, EndoREZ, MTA Fillapex, Pulp Canal Sealer EWT, RoekoSeal and Sealapex and with elutes of the same specimens for 5 succeeding weeks after immersing in simulated body fluid. The cytotoxicity of all root canal sealers was determined using the MTT assay. Data were analyzed using ANOVA and Tukey's test. Results RoekoSeal was the only sealer that did not show any cytotoxic effects (p<0.05. All the other tested sealers exhibited severe toxicity initially (week 0. MTA Fillapex remained moderately cytotoxic after the end of experimental period. Toxicity of the other tested sealers decreased gradually over time. The evaluated root canal sealers presented varying degrees of cytotoxicity, mainly in fresh mode. Conclusions RoekoSeal had no cytotoxic effect both freshly mixed and in the other tested time points. MTA Fillapex was associated with significantly less cell viability when compared to the other tested root canal sealers.

    Objectives (1) Evaluate changes in subjective symptoms in patients following transmastoid canal plugging for superior semicircular canal dehiscence (SSCD) syndrome. (2) Quantify changes in hearing in patients who have undergone transmastoid canal plugging for SSCD syndrome. Study Design Case series with chart review. Setting Single tertiary care institution. Subjects and Methods We retrospectively reviewed patients with SSCD who underwent repair with canal plugging via a transmastoid approach between January 2012 and January 2017. Symptom severity was assessed prospectively (autophony, sound/pressure-induced vertigo, disequilibrium, aural fullness, and pulsatile tinnitus) and after surgery. Pure-tone and speech audiometry were measured before and after surgery. Two-sided Wilcoxon rank-sum tests were used to evaluate changes in subjective symptoms and audiometric outcomes. Results Seventeen patients (19 ears) met inclusion criteria. The superior canal was successfully plugged via the transmastoid approach in all cases. Patients reported a statistically significant improvement in autophony, vertigo, aural fullness, and pulsatile tinnitus ( P study, patients with SSCD demonstrated excellent hearing outcomes and resolution of most otologic symptoms after surgical repair. Transmastoid canal plugging, which has been described to date only in smaller case series, is a safe and effective alternative to the traditional middle cranial fossa approach.

    2017-04-01

    Full Text Available Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal. Research productivity directed at understanding better methods for diagnosing and treating this condition has substantially increased over the last two decades. We now have a sound understanding of the pathophysiology of third mobile window syndromes, higher resolution imaging protocols, and several sensitive and specific diagnostic tests. Furthermore, we have a treatment (surgical occlusion of the superior semicircular canal that has demonstrated efficacy. This review will highlight some of the fundamental insights gained in SCDS, propose diagnostic criteria, and discuss future research directions.

    1992-06-01

    Conventional cleaning and shaping of root canal systems employs hand and/or rotary instrumentation to remove the contents of the canal and shape the canal to receive a filling material. With the advent of the Nd:YAG laser system another method of accomplishing proper cleaning and shaping is evaluated. Single rooted teeth were radiographed bucco- lingually and mesio-distally and were divided into 2 groups. The first group was accessed and the root canal systems cleaned and shaped with a step back technique utilizing hand files and gates glidden burs. At completion of the procedure the teeth were again radiographed at the same positions as those prior to the procedure. The teeth were split longitudinally and examined under scanning electron microscopy to assess cleaning. The second group of teeth were accessed, and cleaning and shaping was accomplished using the Nd:YAG laser in combination with hand files and rotary instruments. These teeth were subjected to the same analysis as those in the first group. The before and after radiographs of each group were subjected to image analysis to determine effectiveness of the two methods in shaping the canal systems. We will discuss the ability of Nd:YAG to clean and shape root canal spaces and remove smear layer and organic tissue remnants from those areas.

    The aim of this study was to compare the cleaning of main and lateral canals using the irrigation methods: negative pressure irrigation (EndoVac system), passive ultrasonic irrigation (PUI) and manual irrigation (MI). Resin teeth were used. After root canal preparation, four lateral canals were made at 2 and 7 mm from the apex. Root canals were filled with contrast solution and radiographed pre- and post-irrigation using digital radiographic system [radiovisiography (RVG)]. The irrigation protocols were: MI1-manual irrigation [22 G needle at 5 mm short of working length-WL]; MI2-manual irrigation (30G needle at 2 mm short of WL); PUI; EV1-EndoVac (microcannula at 1 mm short of WL); EV2-Endovac (microcannula at 3 mm short of WL). The obtained images, initial (filled with contrast solution) and final (after irrigation) were analyzed by using image tool 3.0 software. Statistical analysis was performed by analysis of variance (ANOVA) and Tukey tests (5% significance level). EV1 and EV2, followed by PUI showed better cleaning capacity than manual irrigation (MI1 and MI2) (p irrigation and PUI promoted better cleaning of main and simulated lateral canals. Conventional manual irrigation technique may promote less root canal cleaning in the apical third. For this reason, the search for other irrigation protocols is important, and EndoVac and PUI are alternatives to contribute to irrigation effectiveness.

    Full Text Available The present study describes the histological and mucin histochemical properties of the alimentary canal (AC of the pangas catfish, Pangasius pangasius. The results revealed that the mucosa of the oesophagus was lined by a stratified epithelium containing chloride cells and taste buds which suggested mechanic, gustatory and physiologic roles of the oesophagus in this species. The stomach mucosa was lined by a simple columnar epithelium. The lamina propria-submucosa in cardiac and fundic stomach contained gastric glands. The pyloric stomach had the thickest muscularis layer among all the parts of the AC. The villi showed the maximum height and width in the middle intestine. The tunica muscularis and serosa showed the thinnest thickness among all parts of AC. The mucin histochemistry showed that the goblet cells of oesophagus and intestine contained both neutral and acidic with carboxylated and sulfated mucins and there was not acidic mucins in epithelial cells of the stomach.

    By reviewing retrospectively the HRCT findings in 130 surgically proven cases of chronic otitis media with cholesteatoma, we estimated the sensitivity, specificity, and positive predictability of the HRCT compared to surgical findings. For exposure of the facial canal, the sensitivity, specificity, and positive predictability was 59.7%, 84.9%, and 85.2% respectively. For exposure of the lateral semicircular canal, the sensitivity was 80.6%, the specificity 99.0%, and the positive predictability 96.2%. Conclusively, the diagnostic accuracy of preoperative temporal bone CT regarding the state of the lateral semicircular canal seems to be highly reliable. Gross invasion of the facial canal can be usually detected. However, relatively low sensitivity suggests that evaluation of the ultra-thin structures of the tympanic segment is often problematic.

    Fecal incontinence after the surgical repair of Hirschsprung disease is a potentially preventable complication that carries a negative impact on patient's quality of life. Patients that were previously operated for Hirschsprung disease and presented to our bowel management clinic with the complaint of fecal incontinence were retrospectively reviewed. All patients underwent a rectal examination under anesthesia looking for anatomic explanations for their incontinence. One hundred three patients were identified. 54 patients had a damaged anal canal. 22 patients also had a patulous anus. The operative reports mentioned the pectinate line in 32 patients, in 12 it was not mentioned, and in 10 patients the operative report was not available. All patients with a damaged anal canal suffered from true fecal incontinence; 45 of them are on daily enemas (41 are clean and 4 are still having "accidents"), 7 are not doing bowel management due to noncompliance and 2 patients have a permanent ileostomy. 49 patients did not have a damaged anal canal, 25 of those responded to changes in diet and medication and are having voluntary bowel movements. Fecal incontinence may occur after an operation for Hirschsprung disease. When the anal canal is damaged, incontinence is always present, severe, and probably permanent. The preservation of the anal canal may avoid this complication. Copyright © 2017. Published by Elsevier Inc.

    To evaluate whether passive ultrasonic irrigation (PUI) of 2.5% NaOCl would dissolve necrotic pulp tissue from simulated accessory root canals (SACs) better than passive placement of the irrigant, when temperature was equilibrated between the two treatments. Transparent root canal models (n = 6) were made from epoxy resin. SACs of 0.2 mm diameter were placed at defined angles and positions in the mid-canal and apical area. SACs were filled with necrotic bovine pulp tissue. PUI was performed five times for 1 min each with irrigant replenishment after every minute. Main canal temperature was measured after each minute, and a digital photograph was taken. In control experiments, mock treatments were performed with the same set-up without activation of the file using heated NaOCl to mimic the temperature created by PUI. Experiments were repeated five times. Digital photographs were analysed for the distance of dissolved tissue into the SACs in mm. Overall comparison (sum of dissolved tissue from all five accessory canals) between treatments was performed using paired t-test. Differences between SAC angulation and position after PUI were investigated using anova/Bonferroni (alpha temperature in the main canal to 53.5 +/- 2.7 degrees C after the fifth minute. PUI dissolved a total of 6.4 +/- 2.1 mm, mock treatment controlled for heat: 1.4 +/- 0.6 mm (P temperature.

    To evaluate the effects of working length and root canal preparation technique on crack development in the apical root canal wall. Seventy extracted mandibular premolars were mounted in a resin block with simulated periodontal ligaments and divided into seven groups according to preparation technique and working length: group A, step-back preparation with stainless steel files with working length set at the apical foramen and defined as root canal length (CL); group B, same as for A, except that the working length was CL-1 mm; group C, crown-down preparation with Profile instruments followed by an apical enlargement sequence with CL as working length and group D, same as for C, except that the working length was CL-1 mm. Groups E, F and G served as controls. Groups E and F were prepared only with the crown-down sequence up to CL and CL-1 mm, respectively. Group G was left unprepared. Digital images of the apical root surface (AS) were recorded before preparation, immediately after instrumentation and after removing the apical 1 mm (AS-1 mm) and 2 mm (AS-2 mm) of the root end. Working length significantly affected crack development at AS (P crack development at AS-1 mm (P crack development on the canal wall. Root canal preparation alone, regardless of the technique used, can potentially generate cracks on the apical root canal wall as well as the apical surface. Working 1- mm short of the apical foramen might produce fewer cracks in the apical region.
