    2009-01-01

    Full Text Available Thumb pulp defects are commonly due to avulsion injuries. It is very important to reconstruct these defects using sensate flaps as the thumb pulp needs to be sensate for implementing the various functions of the thumb. A very good option for coverage of these defects is the islanded first dorsal metacarpal artery flap. Our study was done over a period of 2 years and involved 9 consecutive cases of thumb pulp defects treated at our institution. The patients included 8 males and 1 female, ranging in age from 16 to 51 years old. The flap size ranged from 2 x 1.5 cm to 5 x 3 cm. We had only one complication in the form of partial flap necrosis, which fortunately healed following debridement without the need for a secondary procedure. All our cases were done under local anesthesia with tourniquet control. All the patients had good fine touch and average two-point discrimination of 6 mm, which was satisfactory. Our good results further reinforce the islanded first dorsal metacarpal artery flap as one the best flaps for sensate reconstruction of thumb pulp defects. It replaces the soft tissue loss at the thumb pulp with minimal donor site morbidity and with good return of thumb pulp sensation.

  3. Gender difference in metacarpal descent of fifth metacarpal

    To determine the difference in metacarpal descent of fifth metacarpal between men and women. Skyline of the 2nd and 3rd metacarpals were used as reference line, from which the descent of the 5th metacarpal head was measured. The position of 5th metacarpal head was documented as angle X. Metacarpal descent was defined as the difference between angle 'X' in relaxed and clenched fist position. The relaxed position was standardized by placing the forearm, wrist and palm on a shaped woodblock such that the wrist would be held in 25 - 30 degree in extension by a triangular spur, supported the 3rd metacarpal only. It was ensured that the movement of 4th and 5th metacarpals were not impaired. Analysis of variance was performed to compare the significance of means between genders at p < 0.05 level of significance. Metacarpal descent of the 5th metacarpal of both hands was significantly greater for women, with a mean of 7 degree as compared with a mean of 4 degree for the men. This decrease in angle 'X' was significant for the right 5th metacarpal relaxed and fist position and the fist position on the left. In contrast, women showed no significant differences between the various age groups for any of the variables tested.There was no relationship between metacarpal descent and hand dominance.Difference in metacarpal descent between men and women is significant and must be kept in mind when hand function is evaluated in both genders to assess the outcome of treatment and rehabilitation.

    2016-03-01

    Traumatic injuries to the digits resulting in soft tissue or bone loss require reconstruction. Traditionally, local flaps, such as homodigital flaps, heterodigital flaps, pedicled flaps, or distant flaps, are used for digital resurfacing. However, free tissue transfers can be used in selected patients. In this study, we present the use of different free flaps including groin skin flaps, groin osteocutaneous flaps, groin chimeric flaps, second dorsal metacarpal artery flaps, and partial toe flaps for digital reconstruction. A total of 19 digits were treated with 16 free flaps in our hospital. Of the flaps used, 5 were free groin skin flaps, 4 were free partial toe flaps, 3 were free groin chimeric flaps, 2 were free groin osteocutaneous flaps, and 2 were free second dorsal metacarpal artery flaps. The average flap size was 4.7 × 2.0 cm (range, 1.5 × 1 to 5 × 4 cm), and the average operative time was 6.0 hours (range, 4-9 hours). All flaps survived without partial or total necrosis. In conclusion, the free flap is a reliable and safe alternative for digital reconstruction. Moreover, the free groin flap provides not only a chimeric pattern for multiple fingers coverage but also an osteocutaneous pattern for thumb lengthening. The free second dorsal metacarpal artery flap provides a tenocutaneous pattern for tendon reconstruction and soft tissue coverage simultaneously, and the free partial toe flap is an excellent alternative for pulp reconstruction in terms of aesthetic appearance and functional outcome.

  7. Chondromyxoid fibroma of the metacarpal

    This report describes a chondromyxoid fibroma which developed in the distal part of the second metacarpal of a 12-year-old girl. The tumor is rare, perhaps the rarest of all bone tumors, and the occurrence in a metacarpal of a young female is extraordinarily uncommon. (orig.)

  8. Intraosseous schwannoma of the metacarpal

    Intraosseous schwannoma (neurilemmoma) is an extremely rare, benign neoplasm, constituting less than 0.2% of primary bone tumors. It infrequently involves the bones of the hand. We present a case of intraosseous neurilemmoma of the metacarpal. (orig.)

  9. Metacarpal proportions in Australopithecus africanus.

    Green, David J; Gordon, Adam D

    2008-05-01

    Recent work has shown that, despite being craniodentally more derived, Australopithecus africanus had more apelike limb-size proportions than A. afarensis. Here, we test whether the A. africanus hand, as judged by metacarpal shaft and articular proportions, was similarly apelike. More specifically, did A. africanus have a short and narrow first metacarpal (MC1) relative to the other metacarpals? Proportions of both MC breadth and length were considered: the geometric mean (GM) of articular and midshaft measurements of MC1 breadth was compared to those of MC2-4, and MC1 length was compared to MC3 length individually and also to the GM of MC2 and 3 lengths. To compare the extant hominoid sample with an incomplete A. africanus fossil record (11 attributed metacarpals), a resampling procedure imposed sampling constraints on the comparative groups that produced composite intrahand ratios. Resampled ratios in the extant sample are not significantly different from actual ratios based on associated elements, demonstrating the methodological appropriateness of this technique. Australopithecus africanus metacarpals do not differ significantly from the great apes in the comparison of breadth ratios but are significantly greater than chimpanzees and orangutans in both measures of relative length. Conversely, A. africanus has a significantly smaller breadth ratio than modern humans, but does not significantly differ from this group in either measure of relative length. We conclude that the first metacarpals of A. africanus are more apelike in relative breadth while also being more humanlike in relative length, a finding consistent with previous work on A. afarensis hand proportions. This configuration would have likely promoted a high degree of manipulative dexterity, but the relatively slender, apelike first metacarpal suggests that A. africanus did not place the same mechanical demands on the thumb as more recent, stone-tool-producing hominins.

    2009-01-01

    Full Text Available Background: Metacarpal lengthening in the hand is a new application for distraction neo-histiogenesis. Metacarpal lengthening with distraction helps in improvement in pinch function. Thumb lengthening is technically easy in comparison to other metacarpals. We present the operative treatment and post-operative outcome in nine patients with amputations and congenital anomalies. Materials and Methods: Nine patients underwent distraction osteogenesis for the treatment of amputations of the hand and other congenital anomalies. The dominant right hand was operated in eight cases and the left hand in one case. There were six males and three females. Improvement of function was always the aim of surgery. Age range was between 18 and 23 years. Thumb lengthening was performed in five patients and that of the index finger in four patients. Distraction started on the fifth post-operative day at the rate of 0.25 mm/day. Sensory function and bone consolidation was assessed before fixator removal. Results: The mean duration of distraction was 51 days (range, 42-60 days and the distractor was removed at a mean of 150 days (range, 140 and 160 days and the bones were lengthened by a mean of 24 mm (range, 20-28 mm There was improvement of function in all cases. Conclusion: The metacarpal lengthening by distraction histiogenesis in congenital and traumatic amputations is safe and simple method to improve pinch function of hand.

  18. Intraosseous ganglion in the first metacarpal bone

    Intraosseous ganglia occur most frequently in the long bones of the lower limbs, particularly in the medial malleolus of the tibia. They usually appear as radiographically well circumscribed juxta-articular cystic lesions, containing myxoid fibrous tissue histologically. Intraosseous ganglia in the hand are very rare. Most reported cases have involved the carpal bones, in particular the lunate and scaphoid. To our knowledge, the present case is the third report of an intraosseous ganglion appearing in the first metacarpal bone; it arose in a patient who had been on dialysis for 25 years, mimicking amyloidosis of bone.

  19. Thumb Reconstruction Using Foucher’s Flap

    Kola, Nardi

    2016-01-01

    BACKGROUND: Extensive pulp defects of the thumb, with the exposure of tendon or bone, are challenging reconstructive problems. Surgical treatment includes the use of local, regional, and free flaps. AIM: This paper is focused in Foucher’s neuro vascular flap. First DMCA or Foucher’s pedicle flap is a successful thumb reconstruction method, especially in patients not disturbed by its cosmetic appearance. MATERIAL AND METHODS: The first dorsal metacarpal artery (FDMCA) arises from the radial artery in the first intermetacarpal space, just distal to the tendon of the extensor pollicis longus. Pulp area of the thumb is the area where Foucher’s flap is more utilizable. This technique has other applications such as first web reconstruction, thumb lengthening, and following resection of tumors on the dorsum of the hand. RESULTS: We have in study 7 cases with work related trauma in two years period of time, between 2012 and 2014. We had only one partial flap survival and all the other flaps survived entirely. We have also taken in consideration subjective satisfaction with a range score from 4 to 10, cold intolerance, flap area and donor site sensibility with a range score from low to medium to normal. CONCLUSION: Careful pedicle discovery, secured elevation, pedicle strangulation prevention are very important for flap survival.

  2. Biomechanical failure of metacarpal fracture resorbable plate fixation.

    Lionelli, Gerald T; Korentager, Richard A

    2002-08-01

    Metacarpal fractures are a relatively common hand injury that may require operative intervention to ensure adequate reduction and stabilization. The use of permanent hardware, although acceptable, may lead to complications and an increased number of surgical procedures. The use of resorbable hardware such as poly-L-lactic acid and polyglycolic acid copolymer plates and screws may circumvent some of these complications. In vitro studies have demonstrated that the biomechanical characteristics of these resorbable plates may provide the rigid fixation necessary to allow for union of metacarpal fractures in vivo. However, limited clinical data are available regarding the success of their use in this application. The authors present what they believe is the first reported case of the failure of a poly-L-lactic acid and polyglycolic acid copolymer miniplate after use in the fixation of a metacarpal shaft fracture.

  3. Monoaxial distraction of ulna to second metacarpal followed by single bone forearm in massive post infective radial bone loss

    Jitendra N Pal

    2012-01-01

    Full Text Available Introduction: Radial bone loss associated with gross manus valgus deformity can be managed by open reduction internal fixation using intervening strut bone graft, callus distraction using ring or monoaxial fixator, and achieving union by distraction histogenesis. These methods are particularly suitable when bone loss is small. Single or staged procedure is described for congenital as well as in acquired extensive bone loss of radius. Distraction through radial proximal to distal segments, to achieve reduction of distal radio-ulnar joint (DRUJ, is also described in acquired cases. In the present series, functional results of distraction through ulna to 2 nd metacarpal is studied alongwith, functional status of hand, stability of wrist, level of patient′s satisfaction are also studied. Materials and Methods: 7 unilateral cases of radial loss (M = 5, F = 2 affecting 4 right hands of mean age 17 years (range 9 to 24 years were included in this study. They were treated by distracting through ulna to 2 nd metacarpal to achieve DRUJ alignment in first stage. Subsequently ulna was osteotomised and translated to distal stump of radius. It was then fixed to the distal radial remnant in 30° pronation in dominant and 30° supination non dominant hands. Results: Union was achieved in all cases associated with beneficial cross union of distal ulna. Hand functions improved near to normal, with fully corrected stable wrist joint, hypertrophied ulna and without recurrence. All of them had practically complete loss of forearm rotations, however patients were fully satisfied. Conclusion: This method is particularly suitable when associated with 6 cm or more radial bone loss. But when loss is small, sacrifice of one bone may not be justifiable.

  6. Radiodiagnosis of closed fractures of 2-5 metacarpal bones

    A unified method of radiodiagnosis of angular deformities in subcapital fractures of 2-5 metacarpal bones was proposed. It was based on the standardization of the wrist laying for roentgenography of the oblique view strictly at the angle of 45 deg. The projection angle of deformity of the metacarpal bone was measured on a radiogram obtained and then a true value of the angular displacement of the bone fragments to the palm was determined on a nomogram (i.e. on a chart of the ratio of values of the true and projection angles). The healthy metacarpal bone heads were inclined to the palm at the angle of 13-33 deg. It was found that in subcapital fractures of 2-5 metacarpal bones certain self-correction (varying from 10 to 15 deg) of angular deformities was possible in children and adolescents only. Owing to such radiodiagnosis and a differentiated choice of therapeutic methods (in 48.8% of the patients indications for reposition were determined) good anatomical and functional results were obtained in most of the patients (96.9%)

  8. Exogenous attention enhances 2nd-order contrast sensitivity.

    Barbot, Antoine; Landy, Michael S; Carrasco, Marisa

    2011-05-11

    Natural scenes contain a rich variety of contours that the visual system extracts to segregate the retinal image into perceptually coherent regions. Covert spatial attention helps extract contours by enhancing contrast sensitivity for 1st-order, luminance-defined patterns at attended locations, while reducing sensitivity at unattended locations, relative to neutral attention allocation. However, humans are also sensitive to 2nd-order patterns such as spatial variations of texture, which are predominant in natural scenes and cannot be detected by linear mechanisms. We assess whether and how exogenous attention--the involuntary and transient capture of spatial attention--affects the contrast sensitivity of channels sensitive to 2nd-order, texture-defined patterns. Using 2nd-order, texture-defined stimuli, we demonstrate that exogenous attention increases 2nd-order contrast sensitivity at the attended location, while decreasing it at unattended locations, relative to a neutral condition. By manipulating both 1st- and 2nd-order spatial frequency, we find that the effects of attention depend both on 2nd-order spatial frequency of the stimulus and the observer's 2nd-order spatial resolution at the target location. At parafoveal locations, attention enhances 2nd-order contrast sensitivity to high, but not to low 2nd-order spatial frequencies; at peripheral locations attention also enhances sensitivity to low 2nd-order spatial frequencies. Control experiments rule out the possibility that these effects might be due to an increase in contrast sensitivity at the 1st-order stage of visual processing. Thus, exogenous attention affects 2nd-order contrast sensitivity at both attended and unattended locations. PMID:21356228

    2005-03-01

    Implant loosening and mechanical failure of components are frequently reported following metacarpophalangeal (MCP) joint replacement. Studies of the mechanical environment of the MCP implant-bone construct are rare. The objective of this study was to evaluate the predictive ability of a finite element model of the intact second human metacarpal to provide a validated baseline for further mechanical studies. A right index human metacarpal was subjected to torsion and combined axial/bending loading using strain gauge (SG) and 3D finite element (FE) analysis. Four different representations of bone material properties were considered. Regression analyses were performed comparing maximum and minimum principal surface strains taken from the SG and FE models. Regression slopes close to unity and high correlation coefficients were found when the diaphyseal cortical shell was modelled as anisotropic and cancellous bone properties were derived from quantitative computed tomography. The inclusion of anisotropy for cortical bone was strongly influential in producing high model validity whereas variation in methods of assigning stiffness to cancellous bone had only a minor influence. The validated FE model provides a tool for future investigations of current and novel MCP joint prostheses. PMID:15642506

  14. Thermoluminescent characteristics of ZrO2:Nd films

    In this work it is exposed the obtained results after analysing the photo luminescent and thermoluminescent characteristics of activated zirconium oxide with neodymium (ZrO2 :Nd) and its possible application in the UV radiation dosimetry. The realized experiments had as objective to study the characteristics such as the optimum thermal erased treatment, the influence of light on the response, the response depending on the wavelength, the fadeout of the information, the temperature effect, the response depending on the time and the recurring of the response. The results show that the ZrO2 :Nd is a promising material to be used as Tl dosemeter for the UV radiation. (Author)

    2002-01-01

    Full Text Available This paper presents the experiences of the thumb reconstruction with osteofasciocutaneous reverse flap (OFCR flap. In the period between 1987 and 2000 the OFCR flap was used in 15 patients. The youngest of them was 18 and the oldest was 38 years of age. The average age was 25.4. All the patients had post-traumatic amputations. Defects on proximal phalangae and a part of metacarpal bone occurred in two cases. In one case there was an amputation on the base level of proximal phalanx and the metacarpophalangeal (MPH joint was preserved. In all cases of reconstruction the OFCR flap was used, which included antebrachial skin nerves that were anastomosed with digital nerve. The flap nutrition was carried out through the reverse circulation of a. radialis, and the venous drainage through the comitant vein of a. radialis. Superficial veins were not anastomosed. Secondary defects were covered with a free skin graft. All the flaps survived. The bone graft was healed in the period of eight weeks. The sensibility of this flap was regained in the period of three to six months after the surgery. The distance of two-point discrimination (TPD was increased for 30% compared to the same region on the other hand after six months. The opposition of the reconstructed thumb to the other fingers was possible, as well as abduction, adduction and normal grasp. The method of reconstruction of the amputated thumb with the OFCR flap was better than other classical methods because it allowed the reconstruction of all the structures in one surgical operation. The sensibility that was regained represented good protection from injuries. There were no functional damages on the secondary defect. The esthetic result was not good due to the lack of a fingernail.

  1. Metacarpal torsion in apes, humans, and early Australopithecus: implications for manipulatory abilities.

    Drapeau, Michelle S M

    2015-01-01

    Human hands, when compared to that of apes, have a series of adaptations to facilitate manipulation. Numerous studies have shown that Australopithecus afarensis and Au. africanus display some of these adaptations, such as a longer thumb relative to the other fingers, asymmetric heads on the second and fifth metacarpals, and orientation of the second metacarpal joints with the trapezium and capitate away from the sagittal plane, while lacking others such as a very mobile fifth metacarpal, a styloid process on the third, and a flatter metacarpo-trapezium articulation, suggesting some adaptation to manipulation but more limited than in humans. This paper explores variation in metacarpal torsion, a trait said to enhance manipulation, in humans, apes, early australopithecines and specimens from Swartkrans. This study shows that humans are different from large apes in torsion of the third and fourth metacarpals. Humans are also characterized by wedge-shaped bases of the third and fourth metacarpals, making the metacarpal-base row very arched mediolaterally and placing the ulnar-most metacarpals in a position that facilitate opposition to the thumb in power or cradle grips. The third and fourth metacarpals of Au. afarensis are very human-like, suggesting that the medial palm was already well adapted for these kinds of grips in that taxon. Au. africanus present a less clear human-like morphology, suggesting, perhaps, that the medial palm was less suited to human-like manipulation in that taxa than in Au. afarensis. Overall, this study supports previous studies on Au. afarensis and Au. africanus that these taxa had derived hand morphology with some adaptation to human-like power and precision grips and support the hypothesis that dexterous hands largely predated Homo.

  2. Diaphyseal sequestration of the metacarpal and metatarsal bone in cattle

    Between 1990 and 1993 ten cows with diaphyseal sequestration of the metacarpal or metatarsal bone were brought to the Clinic for Food Animals and Horses, University of Bern. History, clinical and radiographic findings at admission, therapy, and clinical and radiographic short- and longterm results were evaluated retrospectively. Six animals had a history of trauma. The metatarsal bone (n = 9) was much more frequently affected than the metacarpal bone (n = 1). Lameness was slight in seven cases and intermediate in three cases. Soft tissue swelling was present in all cases, and fistula formation in eight cases. Sequestrectomy was performed in nine cases, the exuberant new bone circumferentially removed in three of these cases, and the skin primarily closed in all nine cases treated surgically. One animal with a small sequestrum, showing no fistula formation, was treated conservatively. Four to 44 months after surgery, interviews with the owners by telephone revealed that the recovery had been satisfactory in all ten cases. At the same time period, clinical and radiographic examinations of the six animals that were still alive were performed by a veterinarian additionally. Normal limb function had been restored in all six animals, although the affected limb was clearly distinctable from the unaffected contralateral limb, because of its increased diameter. From the results of this study we concluded that longterm prognosis after sequestrectomy is favourable; primary wound closure can be attempted with good success. Cosmetically promising results, however, can only be achieved, if sequestrectomy is performed early enough in the course of the disease or if the exuberant new bone is surgically removed

  4. Propagation of a dorsal cortical fracture of the third metacarpal bone in two horses

    Seemingly, propagation of a dorsal cortical fracture in the third metacarpal bone developed after continued race performance in 2 horses. Historically, both horses had intermittent lameness that had responded to nonsteroidal anti-inflammatory drugs and brief rest periods. However, lameness in both horses had increased in severity. Radiography revealed a dorsal cortical fracture of the third metacarpal bone, with propagation of the fracture plane proximally. Fractures were incomplete and healed with stall rest in both horses

    Natural scenes contain a rich variety of contours that the visual system extracts to segregrate the retinal image into perceptually coherent regions. Covert spatial attention helps extract contours by enhancing contrast sensitivity for 1st-order, luminance-defined patterns at attended locations, while reducing sensitivity at unattended locations, relative to neutral attention allocation. However, humans are also sensitive to 2nd-order patterns such as spatial variations of texture, which are ...

    2014-01-01

    A severe crush injury to the hand is devastating to patients. Under conditions in which the crush force is too great, the digits are not viable candidates for replantation. We present two cases in which the patients suffered from loss of the thumb ray at the first carpometacarpal joint and skin defect at the radial side. The tendons, radial nerve and metacarpal bone of the index finger were injured, and the second metacarpal head was retained. There was a comminuted fracture of the trapezium in both patients. The treatment protocols consisted of the index finger pollicization and the free anterolateral thigh flap transfer. The procedure was performed in a single operation. The new thumb is able to provide a stable post for pinch and grip after six months follow-up. Both patients were satisfied with the function and appearance of the reconstructed thumb.

    Pisoni, L; Del Magno, S; Cinti, F; Dalpozzo, B; Bellei, E; Cloriti, E; Joechler, M

    2014-01-01

    Ectrodactyly is a rare developmental anomaly of the distal part of the forelimb. It is characterized by the presence of an abnormal longitudinal soft tissue and osseous separation or cleft between the digits and the metacarpal bones. It can be associated with hypoplasia, aplasia and malformation of one or more bones of the antebrachium, carpus, metacarpus and digits. Unilateral ectrodactyly and moderate lameness were diagnosed in a young female dog. The dog was treated surgically with reconstruction of soft tissues and stabilization of the metacarpal bones by two nylon cerclage sutures. After three years a mild residual lameness was present. Radiographic signs of synostosis between the metacarpal bones II, III and IV with presence of a cleft between carpal bones II and III were observed. PMID:24569849

  13. Super Boiler 2nd Generation Technology for Watertube Boilers

    Mr. David Cygan; Dr. Joseph Rabovitser

    2012-03-31

    This report describes Phase I of a proposed two phase project to develop and demonstrate an advanced industrial watertube boiler system with the capability of reaching 94% (HHV) fuel-to-steam efficiency and emissions below 2 ppmv NOx, 2 ppmv CO, and 1 ppmv VOC on natural gas fuel. The boiler design would have the capability to produce >1500 F, >1500 psig superheated steam, burn multiple fuels, and will be 50% smaller/lighter than currently available watertube boilers of similar capacity. This project is built upon the successful Super Boiler project at GTI. In that project that employed a unique two-staged intercooled combustion system and an innovative heat recovery system to reduce NOx to below 5 ppmv and demonstrated fuel-to-steam efficiency of 94% (HHV). This project was carried out under the leadership of GTI with project partners Cleaver-Brooks, Inc., Nebraska Boiler, a Division of Cleaver-Brooks, and Media and Process Technology Inc., and project advisors Georgia Institute of Technology, Alstom Power Inc., Pacific Northwest National Laboratory and Oak Ridge National Laboratory. Phase I of efforts focused on developing 2nd generation boiler concepts and performance modeling; incorporating multi-fuel (natural gas and oil) capabilities; assessing heat recovery, heat transfer and steam superheating approaches; and developing the overall conceptual engineering boiler design. Based on our analysis, the 2nd generation Industrial Watertube Boiler when developed and commercialized, could potentially save 265 trillion Btu and $1.6 billion in fuel costs across U.S. industry through increased efficiency. Its ultra-clean combustion could eliminate 57,000 tons of NOx, 460,000 tons of CO, and 8.8 million tons of CO2 annually from the atmosphere. Reduction in boiler size will bring cost-effective package boilers into a size range previously dominated by more expensive field-erected boilers, benefiting manufacturers and end users through lower capital costs.

  14. [The "candlestick" technique for the correction of certain types of congenital metacarpal synotosis].

    Foucher, G; Medina, J; Bollecker, V; Lorea, P

    2002-10-01

    Metacarpal synostosis is a rare congenital hand malformation requiring only occasionally a surgical correction. However in case of divergent epiphyses there is a progressive accentuation of the deformity. In the "Y" type of symmetrical synostosis, the authors propose a trapezoidal osteotomy with upside down relocation allowing realignement of the epiphyses without distant bone donor site.

  16. Aggressive Behavior of a Giant Cell Tumor Involving the Metacarpal Bone During Pregnancy: Case Report

    Giant cell tumors are benign osteolytic tumors with a variable degree of aggressiveness. We report a rare case of a giant cell tumor involving the metacarpal bone, which was detected during pregnancy and showed rapid progression on a follow-up examination.

  17. Incomplete oblique sagittal fractures of the dorsal cortex of the third metacarpal bone in six horses

    To describe incomplete oblique sagittal dorsal cortical fractures of the equine third metacarpal bone, their surgical repair, and subsequent performance of the horses. Retrospective examination of medical records and racing performance. Six Thoroughbred race horses, 2 to 4 years of age. Radiographic confirmation of all fractures preceded general anesthesia and surgical correction. Three fractures were treated by intracortical compression using screws placed in lag fashion, and five fractures were treated by osteostixis. Race records were reviewed for each horse to determine performance after surgery. Fractures were best observed on palmarodorsal radiographic projections. Three horses treated by intracortical compression returned to racing, but fracture recurred in one horse and was treated by osteostixis. This horse and the other three horses treated by osteostixis raced after surgery. Horses with incomplete oblique sagittal fractures of the dorsal cortex of the third metacarpal bone can race after surgical management of the fracture by screws placed in lag fashion or osteostixis. The authors' preferred surgical procedure for managing this fracture is osteostixis. Palmarodorsal radiographic projections of the third metacarpal bone are recommended in young Thoroughbred race horses suspected of having dorsal metacarpal stress fractures

  18. Some observations on lameness associated with pain in the proximal metacarpal region

    The carpus and metacarpus of 40 horses which were free from lameness and 40 horses with lameness associated with the metacarpophalangeal joint or more distal limb were examined radiographically (Group A). The opacity of the proximal third of the third metacarpal bone was regular, with a uniform trabecular pattern. Osseous cyst-like lesions (OCLLs) were identified in the radial carpal bone (1), the ulnar carpal bone (2), the second carpal bone (15) and the fourth carpal bone (1). Thirty-one of 638 horses (4.8 percent) with forelimb lameness had pain localised to the proximal metacarpal region using local anaesthesia (Group B). All these horses were examined radiographically and an ultrasonographic examination was performed in seven. No definitive diagnosis was reached in 16 horses, seven of which had an OCLL in one of the carpal bones or the second metacarpal bone. One horse had, in addition to a poorly defined lucent area in the second carpal bone, radiographic evidence of degenerative joint disease of the carpometacarpal joint and an hypoechoic lesion in the accessory ligament of the deep digital flexor tendon. One horse had an hypoechoic lesion in the proximal part of the suspensory ligament. Abnormalities of the trabecular structure of the third metacarpal bone were identified in 13 horses. In 11 of these there was a vertically orientated lucent line, usually surrounded by sclerotic bone. These lucent lines may represent fatigue fractures seen end on. In one horse an horizontal lucent line was seen. One of these 13 horses also had a lesion in the proximal part of the suspensory ligament. Ten of the 13 (77 per cent) horses with presumed fractures of the third metacarpal bone recovered completely, whereas only eight of the 16 (50 per cent) horses in which no definitive diagnosis was reached returned to their former function

  1. 2nd International technical meeting on small reactors

    The 2nd International Technical Meeting on Small Reactors was held on November 7-9, 2012 in Ottawa, Ontario. The meeting was hosted by Atomic Energy of Canada Limited (AECL) and Canadian Nuclear Society (CNS). There is growing international interest and activity in the development of small nuclear reactor technology. This meeting provided participants with an opportunity to share ideas and exchange information on new developments. This Technical Meeting covered topics of interest to designers, operators, researchers and analysts involved in the design, development and deployment of small reactors for power generation and research. A special session focussed on small modular reactors (SMR) for generating electricity and process heat, particularly in small grids and remote locations. Following the success of the first Technical Meeting in November 2010, which captured numerous accomplishments of low-power critical facilities and small reactors, the second Technical Meeting was dedicated to the achievements, capabilities, and future prospects of small reactors. This meeting also celebrated the 50th Anniversary of the Nuclear Power Demonstration (NPD) reactor which was the first small reactor (20 MWe) to generate electricity in Canada.

  2. APTWG: 2nd Asia-Pacific Transport Working Group Meeting

    This conference report summarizes the contributions to and discussions at the 2nd Asia-Pacific Transport Working Group Meeting held in Chengdu, China, from 15 to 18 May 2012. The topics of the meeting were organized under five main headings: momentum transport, non-locality in transport, edge turbulence and L–H transition, three-dimensional effects on transport physics, and particle, momentum and heat pinches. It is found that lower hybrid wave and ion cyclotron wave induce co-current rotation while electron cyclotron wave induces counter-current rotation. A four-stage imaging for low (L) to high (H) confinement transition gradually emerges and a more detailed verification is urgently expected. The new edge-localized modes mitigation technique with supersonic molecular beam injection was approved to be effective to some extent on HL-2A and KSTAR. It is also found that low collisionality, trapped electron mode to ion temperature gradient transition (or transition of higher to lower density and temperature gradients), fuelling and lithium coating are in favour of inward pinch of particles in tokamak plasmas.

    The aim of this study was to examine if a propeller thoracodorsal artery perforator (TAP) flap can be used for breast reconstruction. Fifteen women were reconstructed using a propeller TAP flap, an implant, and an ADM. Preoperative colour Doppler ultrasonography was used for patient selection to...... major complications needing additional surgery. One flap was lost due to a vascular problem. Breast reconstruction can be performed by a propeller TAP flap without cutting the descending branch of the thoracodorsal vessels. However, the authors would recommend that a small cuff of muscle is left around...

    Yoshiaki Sakamoto

    2014-01-01

    Full Text Available We describe a combination of the common rhomboid flap and bilobed flap and provide an example of its use. The rhombic bilobed flap is simple to use and is associated with fewer complications, such as pin-cushioning and standing cone deformities, while minimizing the risk of skin necrosis and tension on the flap.

  9. Complex Dorsal Dislocation of the Metacarpophalangeal Joint: The Deep Transverse Metacarpal Ligament as a Barrier to Reduction

    DeCoster, Thomas A; McGrew, Deborah; Omer, George E.

    1988-01-01

    Dorsal dislocation of the second metacarpophalangeal (MCP) joint may involve dorsal displacement of the deep transverse metacarpal ligament (DTMCL). In addition to retraction of the volar plate, reduction of the deep transverse metacarpal ligament to its normal volar position is necessary to achieve stable, complete reduction of the MCP joint. The factors associated with this pathologic condition are reviewed as well as an anatomic study of the mechanism of injury.

    The NASA Real Time Mission Monitor (RTMM) is a visualization and information system that fuses multiple Earth science data sources, to enable real time decision-making for airborne and ground validation experiments. Developed at the National Aeronautics and Space Administration (NASA) Marshall Space Flight Center, RTMM is a situational awareness, decision-support system that integrates satellite imagery and orbit data, radar and other surface observations (e.g., lightning location network data), airborne navigation and instrument data sets, model output parameters, and other applicable Earth science data sets. The integration and delivery of this information is made possible using data acquisition systems, network communication links, network server resources, and visualizations through the Google Earth virtual globe application. In order to improve the usefulness and efficiency of the RTMM system, capabilities are being developed to allow the end-user to easily configure RTMM applications based on their mission-specific requirements and objectives. This second generation RTMM is being redesigned to take advantage of the Google plug-in capabilities to run multiple applications in a web browser rather than the original single application Google Earth approach. Currently RTMM employs a limited Service Oriented Architecture approach to enable discovery of mission specific resources. We are expanding the RTMM architecture such that it will more effectively utilize the Open Geospatial Consortium Sensor Web Enablement services and other new technology software tools and components. These modifications and extensions will result in a robust, versatile RTMM system that will greatly increase flexibility of the user to choose which science data sets and support applications to view and/or use. The improvements brought about by RTMM 2nd generation system will provide mission planners and airborne scientists with enhanced decision-making tools and capabilities to more

  11. 2nd interface between ecology and land development in California

    Keeley, Jon E.; Baer-Keeley, Melanie; Fortheringham, C.J.

    2000-01-01

    The 2nd Interface Between Ecology and Land Development Conference was held in association with Earth Day 1997, five years after the first Interface Conference. Rapid population growth in California has intensified the inevitable conflict between land development and preservation of natural ecosystems. Sustainable development requires wise use of diminishing natural resources and, where possible, restoration of damaged landscapes. These Earth Week Celebrations brought together resource managers, scientists, politicians, environmental consultants, and concerned citizens in an effort to improve the communication necessary to maintain our natural biodiversity, ecosystem processes and general quality of life. As discussed by our keynote speaker, Michael Soule, the best predictor of habitat loss is population growth and nowhere is this better illustrated than in California. As urban perimeters expand, the interface between wildlands and urban areas increases. Few problems are more vexing than how to manage the fire prone ecosystems indigenous to California at this urban interface. Today resource managers face increasing challenges of dealing with this problem and the lead-off section of the proceedings considers both the theoretical basis for making decisions related to prescribed burning and the practical application. Habitat fragmentation is an inevitable consequence of development patterns with significant impacts on animal and plant populations. Managers must be increasingly resourceful in dealing with problems of fragmentation and the often inevitable consequences, including susceptibility to invasive oganisms. One approach to dealing with fragmentation problems is through careful landplanning. California is the national leader in the integration of conservation and economics. On Earth Day 1991, Governor Pete Wilson presented an environmental agenda that promised to create between land owners and environmentalists, agreements that would guarantee the protection of

  12. The association between metacarpal ratio, radiographic hand and knee osteoarthritis and its progression after meniscectomy

    Paradowski, P T; Lohmander, Stefan; Englund, Martin Kristian

    2013-01-01

    OBJECTIVE: To examine whether the ratio of the second and fourth metacarpal bone length (MC2:MC4) in subjects with prior meniscectomy of the knee is associated with radiographic hand and knee osteoarthritis (OA) and its progression. DESIGN: We assessed 219 subjects (175 men and 44 women) twice with...... a follow-up time ranging from 4 to 10 years. Participants had all undergone prior meniscectomy. The subjects were of mean (SD) 53 (11) years of age at the first radiographic examination. One observer measured the metacarpal lengths of both hands. We used the average MC2:MC4 from left and right hand...... divided into tertiles as the exposure variable, using the highest tertile, i.e., "female" pattern as reference category. Radiographic OA of both hands and knees and its progression were evaluated on subject level as our outcomes. We used logistic regression to evaluate the possible association of MC2:MC4...

  13. Florid reactive periostitis of the metacarpal and phalanx: 2 case reports.

    Gao, Zhenhua; Wang, Jifei; Wang, Zhuo; Meng, Quanfei

    2013-11-01

    Florid reactive periostitis is a rare benign fibro-osseous proliferative lesion of soft tissue and is mainly composed of fibrous connective tissue and mature bone. The lesion usually occurs in the finger and seldom in the metacarpal. The lesion mimics malignant and infectious disorders, thus often leading to inappropriate treatment. Radiography usually shows an ossified mass attached to the underlying hand bones without interruption of the cortex. We report 1 case of florid reactive periostitis with unossified mass and underlying bone marrow edema in the metacarpal of hand and 1 case with adjacent cortical destruction in the phalanx. In addition, we describe the imaging findings of computed tomography CT and magnetic resonance imaging MRI and discuss their diagnostic values compared with routine radiographic examination.

  14. Sexual dimorphism of the metacarpals in contemporary Cretans: Are there differences with mainland Greeks?

    Nathena, Despoina; Gambaro, Laura; Tzanakis, Nikolaos; Michalodimitrakis, Manolis; Kranioti, Elena F

    2015-12-01

    Sex in the adult skeleton can usually be reliably determined through an assessment of features found on the pelvis and cranium. In the lack of these elements it is necessary to elaborate other methods to establish sex in skeletonised remains recovered in forensic cases. Standards for other bones (e.g. humerus, metacarpals and metatarsals) have already been established for the Greek population. The aim of this study is to determine whether the standards for metacarpals provided from a study on the Athens collection are representative of a modern Cretan population. Using a digital caliper we took 7 measurements on each one of the left and right metacarpal bones of 108 adult individuals from a modern collection from Crete. Totally twenty formulae for left and right bones created from the Athens collection were used to sex the sample of this study. The overall classification accuracy obtained for our sample was very close to the cross-validated accuracy reported by the authors. However, looking at the classification accuracy for males and females, a consistent trend for low classification rates in females was observed. New formulae were developed for the Cretan sample yielding up to 85% classification accuracy. This study clearly indicates that the standards for metacarpals developed from the Athens collection are not appropriate for application in forensic cases for the island of Crete as they do not represent the local population efficiently. This may hold true for other regions of Greece thus great caution should be taken when applying these standards. Obviously more research is needed to confirm these results. PMID:26462576

    Gupta Rakesh

    2007-01-01

    Full Text Available Background: Optimized functional results are difficult to achieve following hand injuries. This prospective study was undertaken to evaluate the functional outcome after surgical stabilization of metacarpal and phalangeal fractures. Materials and Methods: Forty-five fractures of digits of hand in 31 patients were managed by surgical stabilization. Five fractures were fixed with closed reduction and percutaneous Kirschner wire fixation; 10 with external fixator; 26 with open reduction and Kirschner wire fixation; and four with open reduction and plate and screw or screw fixation. Results: Final evaluation of the patients was done at the end of three months. It was based on total active range of motion for digital functional assessment as suggested by the American Society for surgery of hand. Overall results were excellent to good in 87%. Better total active range of motion (excellent grade was observed in metacarpal fractures (47% versus phalanx fractures (31%; closed fractures (57% versus open fractures (27%; and single digit involvement (55% versus multiple digits (29%. Excellent total active range of motion was observed with all four plate and screw/ screw fixation technique (100% and closed reduction and percutaneous kirschner wire fixation (60%. Twenty-two complications were observed in 10 patients with finger stiffness being the most common. Conclusion: Surgical stabilization of metacarpal and phalangeal fractures of hand seems to give good functional outcome. Closed fractures and fractures with single digit involvement have shown a better grade of total active range of motion.

    The 2nd workshop on Germanium (Ge) detectors and technology was held at the University of South Dakota on September 14-17th 2014, with more than 113 participants from 8 countries, 22 institutions, 15 national laboratories, and 8 companies. The participants represented the following big projects: (1) GERDA and Majorana for the search of neutrinoless double-beta decay (0νββ) (2) SuperCDMS, EDELWEISS, CDEX, and CoGeNT for search of dark matter; (3) TEXONO for sub-keV neutrino physics; (4) AGATA and GRETINA for gamma tracking; (5) AARM and others for low background radiation counting; (5) as well as PNNL and LBNL for applications of Ge detectors in homeland security. All participants have expressed a strong desire on having better understanding of Ge detector performance and advancing Ge technology for large-scale applications. The purpose of this workshop was to leverage the unique aspects of the underground laboratories in the world and the germanium (Ge) crystal growing infrastructure at the University of South Dakota (USD) by brining researchers from several institutions taking part in the Experimental Program to Stimulate Competitive Research (EPSCoR) together with key leaders from international laboratories and prestigious universities, working on the forefront of the intensity to advance underground physics focusing on the searches for dark matter, neutrinoless double-beta decay (0νββ), and neutrino properties. The goal of the workshop was to develop opportunities for EPSCoR institutions to play key roles in the planned world-class research experiments. The workshop was to integrate individual talents and existing research capabilities, from multiple disciplines and multiple institutions, to develop research collaborations, which includes EPSCor institutions from South Dakota, North Dakota, Alabama, Iowa, and South Carolina to support multi-ton scale experiments for future. The topic areas covered in the workshop were: 1) science related to Ge

  17. Flapping of Insectile Wings

    Huang, Yangyang; Kanso, Eva

    2015-11-01

    Insects use flight muscles attached at the base of the wings to produce impressive wing flapping frequencies. Yet the effects of muscle stiffness on the performance of insect wings remain unclear. Here, we construct an insectile wing model, consisting of two rigid wings connected at their base by an elastic torsional spring and submerged in an oscillatory flow. The wing system is free to rotate and flap. We first explore the extent to which the flyer can withstand roll perturbations, then study its flapping behavior and performance as a function of spring stiffness. We find an optimal range of spring stiffness that results in large flapping amplitudes, high force generation and good storage of elastic energy. We conclude by conjecturing that insects may select and adjust the muscle spring stiffness to achieve desired movement. These findings may have significant implications on the design principles of wings in micro air-vehicles.

    2011-07-01

    Nanocrystalline Ba2NdSbO6, a complex cubic perovskite metal oxide, powders were synthesized by a self-sustained combustion method employing citric acid. The product was characterized by X-ray diffraction, differential thermal analysis, thermogravimetric analysis, Fourier transform infrared spectroscopy, transmission electron microscopy and scanning electron microscopy. The as-prepared powders were single phase Ba2NdSbO6 and a mixture of polycrystalline spheroidal particles and single crystalline nanorods. The Ba2NdSbO6 sample sintered at 1500°C for 4 h has high density (∼ 95% of theoretical density). Sintered nanocrystalline Ba2NdSbO6 had a dielectric constant of ∼ 21; and dielectric loss = 8 × 10-3 at 5 MHz.

  10. Control of Flap Vortices

    Greenblatt, David

    2005-01-01

    A wind tunnel investigation was carried out on a semi-span wing model to assess the feasibility of controlling vortices emanating from outboard flaps and tip-flaps by actively varying the degree of boundary layer separation. Separation was varied by means of perturbations produced from segmented zero-efflux oscillatory blowing slots, while estimates of span loadings and vortex sheet strengths were obtained by integrating wing surface pressures. These estimates were used as input to inviscid rollup relations as a means of predicting changes to the vortex characteristics resulting from the perturbations. Surveys of flow in the wake of the outboard and tip-flaps were made using a seven-hole probe, from which the vortex characteristics were directly deduced. Varying the degree of separation had a marked effect on vortex location, strength, tangential velocity, axial velocity and size for both outboard and tip-flaps. Qualitative changes in vortex characteristics were well predicted by the inviscid rollup relations, while the failure to account for viscosity was presumed to be the main reason for observed discrepancies. Introducing perturbations near the outboard flap-edges or on the tip-flap exerted significant control over vortices while producing negligible lift excursions.

    Whenever there is soft tissue loss from the perineum there are many options for reconstruction. These include allowing the wound to heal by secondary intention and the use of local random or axial pattern flaps, regional flaps, or free flaps. The axial skin flap can be defined as a flap based on known constant vessels of the subcutaneous tissue and its vena comitantes. The perforator flap on the other hand is a randomly selected perforator consisting of an artery with vena comitantes, which p...

    de Góes Ribeiro, Arthur; Gonçalez, Daniel Hidalgo; Filho, João Manoel Fonseca; da Fonseca, Guilherme Marques; Costa, Antonio Carlos; Chakkour, Ivan

    2016-01-01

    Objective The aim of this study was to establish an indirect, easy-to-use, predictable and safe means of obtaining the true degree of displacement of fractures of the neck of the fifth metacarpal bone, through oblique radiographic views. Methods An anatomical specimen from the fifth human metacarpal was dissected and subjected to ostectomy in the neck region. A 1-mm Kirschner wire was fixed to the base of the fifth metacarpal bone, perpendicular to the longitudinal axis of the bone and parallel to the ground. Another six Kirschner wires of the same diameter were bent over and attached to the ostectomized bone to simulate fracture displacement. Axial rotation of the metacarpus was used to create oblique radiographic views. Radiographic images were generated with different angles and at several degrees of rotation of the bone. Results We deduced a mathematical formula that showed the true displacement of fractures of the neck of the fifth metacarpal bone by means of oblique radiographs. Conclusions Oblique radiographs at 30̊ of supination provided the best view of the bone and least variation from the real value of the displacement of fractures of the fifth metacarpal bone. The mathematical formula deduced was concordant with the experimental model used. PMID:27069882

  15. Incomplete fracture of the proximo-palmar aspect of the third metacarpal bone

    Previous descriptions of incomplete longitudinal fractures and fatigue injury of the proximopalmar aspect of the third metacarpal bone (McIII) have focused on diagnostic imaging findings, especially in racehorses. Objectives: To document the case details, clinical features, response to diagnostic analgesia, diagnostic imaging findings and follow-up data in a large group of horses with an incomplete longitudinal fracture or fatigue injury of the proximopalmar medial aspect of the McIII. Materials And Methods: Horses were included in the study if pain was localised to the proximopalmar aspect of the metacarpal region, with radiological evidence of an incomplete longitudinal fracture or generalised increased radiopacity in the proximopalmar medial aspect of the McIII, or focal increased radiopharmaceutical uptake (IRU) in the proximopalmar aspect of the McIII. Age, breed, gender, height, bodyweight, work discipline, work history, duration of lameness, clinical signs and responses to diagnostic analgesia were recorded. Radiographic and scintigraphic images were assessed subjectively and objectively. Results: There were 55 horses representing a broad spectrum of ages and work disciplines, 73% of which had radiological abnormalities. The majority had no localising clinical signs, although 73% of horses with radiological abnormalities showed a characteristic pattern of lameness. Lameness was generally worse in straight lines than in circles. Increased radiopharmaceutical uptake ranged from mild to intense in the lame limb; 14% of nonlame limbs had mild IRU. Of horses for which long-term follow-up was available, 98% returned to full athletic function. Conclusions And Potential Relevance: Incomplete longitudinal fractures and fatigue injury of the proximopalmar medial aspect of the McIII may occur in horses of many types and sports disciplines, and are not confined to immature performance horses. They should be considered an important differential diagnosis for proximal

    Fifty-two of digital, metacarpal or metatarsal canine tumors and 48 pododermatitis lesions were reviewed retrospectively. The tumors were divided into 42 malignant neoplasms, 6 benign neoplasms and 4 non-neoplastic tumor-like growths. The distribution and radiographic changes of the lesions associated with the tumors and inflammation were compared. Pododermatitis and benign processes could not be radiographically differentiated from malignant neoplasms of the foot; however, lesions exhibiting osteolysis were more likely (p < 0.05) to be associated with malignant neoplasms

    We analyse the extent of intergenerational transmission through parental capital, ethnic capital and neighbourhood effects on several aspects of the school-to-work transition of 2nd generation immigrants and young ethnic Danes. The main findings are that parental capital has strong positive effects...... on the probability of completing a qualifying education and on the entry into the labour market, but it has a much smaller impact on the duration of the first employment spell and on the wage level. Growing up in neighbourhoods with a high concentration of immigrants is associated with negative...... labour market prospects both for young natives and 2nd generation immigrants....

  19. Monitoring North Korea Explosions: Status and Result of 1st and 2nd Tests (Invited)

    Chi, H.; Lee, H.; Shin, J.; Park, J.; Sheen, D.; Kim, G.; Che, I.; Lim, I.; Kim, T.

    2009-12-01

    Through data exchanging with China, Russia and Japan, KIGAM could monitor North Korea explosion tests in near real time with azimuthal full coverage from the test site. Except for the East Sea (Japan Sea) side, the seismic stations are distributed uniformly along the boundaries of North Korea and adjacent countries, and only stations with the distance of 200 to 550 Km from the test site were considered. Irrespective of azimuthal directions of stations from the test site, the conventional discrimination, Pn/Lg spectral ratio clearly showed that both tests were explosion. But mb-Ms discrimination did not show apparently the known pattern of explosion for both tests. Body wave magnitude, mb(Pn) of 2nd test, which was evaluated as 4.5 by KIGAM, varies with directional location of stations widely from 4.1 to 5.2. The magnitude obtained from Lg, mb(Lg), showed narrow variation between 4.3 to 4.7 with the average of 4.5. In the case of 1st test, both mb(Pn) and mb(Lg) showed equivalently large variation with directional station location. The error ellipses of epicentral determination of test site for 1st and 2nd tests showed almost identical pattern if they were separately calculated with the same configuration of stations. But the combined use of 1st and 2nd test data showed that 2nd test site was moved approximately 2 Km westward from 1st site. The cut-off frequencies of P wave of 1st and 2nd tests showed no or negligible difference even though the estimated yield of 2nd test were much larger than that of 1st one. The ratio of 1st and 2nd P-wave amplitudes showed from 2 to 3.1 times. Correspondingly the estimated energy or yield were ranged from 4 to roughly 10 times. KIGAM evaluated the yield of 2nd test were 8 times in the average larger than that of 1st one.

    Through data exchanging with China, Russia and Japan, KIGAM could monitor North Korea explosion tests in near real time with azimuthally full coverage from the test site. Except for the East Sea (Japan Sea) side, the seismic stations are distributed uniformly along the boundaries of North Korea and adjacent countries. The error ellipses of epicentral determination of test site for 1st and 2nd tests showed almost identical pattern if they were separately calculated with the same configuration of stations. But the combined use of the 1st and the 2nd test data showed that the 2nd test site was moved approximately 2 Km westward from 1st site. The Pn/Lg spectral ratio clearly discriminate these events from two nearby natural earthquakes above 4 Hz. Full moment tensor inversion also indicate the 2nd test had a very large isotropic component. But mb-Ms discrimination, which has been considered one of the most reliable discriminants for separating explosions and earthquakes, did not show apparently the known pattern of explosion for both tests. Body wave magnitude, mb(Pn) of the 2nd test, which was evaluated as 4.5 by KIGAM, varies with directional location of stations widely from 4.1 to 5.2. The magnitude obtained from Lg, mb(Lg), showed narrow variation between 4.3 to 4.7 with the average of 4.5. In the case of both 1st and 2nd tests, both mb(Pn) and mb(Lg) showed equivalently large variation with directional station location. These variations are mainly due to lateral variation of crustal structures surrounding the test site. Remarkably mb(Lg) showed very linear relationship with mb(Pn). By considering attenuation characteristics according to the propagation path, the variations could be effectively reduced. The cut-off frequencies of P wave of both tests showed no or negligible difference even though the estimated yield of the 2nd test were much larger than that of the 1st one. The ratio of P-wave amplitudes of two tests showed from 2 to 3.1 times. Correspondingly the

  10. Performance and validation of COMPUCEA 2nd generation for uranium measurements in physical inventory verifications

    Full text: In order to somewhat alleviate the kind of logistical problems encountered in the in-field measurements with the current COMPUCEA equipment (COMbined Product for Uranium Content and Enrichment Assay), and with the expected benefits of saving some time and costs for the missions in mind, ITU is presently developing a 2nd generation of the COMPUCEA device. This new development also forms a task in the support programme of the Joint Research Centre of the European Commission to the IAEA. To validate the in-field performance of the newly developed 2nd generation COMPUCEA, a prototype has been tested together with the 1st generation equipment during physical inventory verification (PIV) measurements in different uranium fuel fabrication plants in Europe. In this paper we will present the prototype of COMPUCEA 2nd generation, its hardware as well as the software developed for the evaluation of the U content and 235U enrichment. We will show a comparison of the performance of the 2nd generation with the 1st generation on a larger number of uranium samples measured during the in-field PIVs. The observed excellent performance of the new COMPUCEA represents an important step in the validation of this new instrument. (author)

    Sandra Olivia; Natalina Natalina; Felix Hartono

    2013-01-01

    Flap surgery is treatment for periodontal disease with alveolar bone destruction. Surgical periodontal flap with conventional incision will result in gingival recession and loss of interdental papillae after treatment. Dilemma arises in areas required high aesthetic value or regions with a fixed denture. It is challenging to perform periodontal flap with good aesthetic results and minimal gingival recession. This case report aimed to inform and to explain the work procedures, clinical and rad...

    2015-11-01

    We study the flapping of a flag in an inviscid channel flow. We focus especially on how quantities vary with channel spacing. As the channel walls move inwards towards the flag, heavier flags become more unstable, while light flags' stability is less affected. We use a vortex sheet model to compute large-amplitude flapping, and find that the flag undergoes a series of jumps to higher flapping modes as the channel walls are moved towards the flag. Meanwhile, the drag on the flag and the energy lost to the wake first rise as the walls become closer, then drop sharply as the flag moves to a higher flapping mode.

  17. Keystone flaps in coloured skin: Flap technology for the masses?

    Satish P Bhat

    2013-01-01

    Full Text Available Introduction: Viscoelastic properties of skin in coloured ethnic groups are less favourable compared to Caucasians for executing Keystone flaps. Keystone flaps have so far been evaluated and reported only in Caucasians. The potential of Keystone flaps in a coloured ethnic group is yet unknown. Aim: This article reviews the experience to reconstruct skin defects presenting in a coloured ethnic group, by using Keystone flaps, with a review of existing literature. Design: Uncontrolled case series. Materials and Methods: This retrospective review involves 55 consecutive Keystone flaps used from 2009 to 2012, for skin defects in various locations. Patient demographic data, medical history, co-morbidity, surgical indication, defect features, complications, and clinical outcomes are evaluated and presented. Results: In this population group with Fitzpatrick type 4 and 5 skin, the average patient age was 35.73. Though 60% of flaps (33/55 in the series involved specific risk factors, only two flaps failed. Though seven flaps had complications, sound healing was achieved by suitable intervention giving a success rate of 96.36%. Skin grafts were needed in only four cases. Conclusions: Keystone flaps achieve primary wound healing for a wide spectrum of defects with an acceptable success rate in a coloured skin population with unfavorable biophysical properties. By avoiding conventional local flaps and at times even microsurgical flaps, good aesthetic outcome is achieved without additional skin grafts or extensive operative time. All advantages seen in previous studies were verified. These benefits can be most appreciated in coloured populations, with limited resources and higher proportion of younger patients and unfavorable defects.

  20. Revised data for 2nd version of nuclear criticality safety handbook/data collection

    This paper outlines the data prepared for the 2nd version of Data Collection of the Nuclear Criticality Safety Handbook. These data are discussed in the order of its preliminary table of contents. The nuclear characteristic parameters (k∞, M2, D) were derived, and subcriticality judgment graphs were drawn for eleven kinds of fuels which were often encountered in criticality safety evaluation of fuel cycle facilities. For calculation of criticality data, benchmark calculations using the combination of the continuous energy Monte Carlo criticality code MVP and the Japanese Evaluated Nuclear Data Library JENDL-3.2 were made. The calculation errors were evaluated for this combination. The implementation of the experimental results obtained by using NUCEF facilities into the 2nd version of the Data Collection is under discussion. Therefore, related data were just mentioned. A database is being prepared to retrieve revised data easily. (author)

  1. Analysis of plume oxidation during the air pollution episode of September 2nd 1998

    Harrison, R.M.; Baggot, S.

    2001-08-01

    This study was commissioned by the Environment Agency in order to provide further investigation into the air pollution episode of September 2nd, 1998 which afflicted parts of the Midlands and South Yorkshire. A report by the Environment Agency based upon numerical modelling by the Meteorological Office indicated a number of major industrial facilities as the source of the emissions responsible for the episode. In this report an investigation is made of likely chemical changes during airmass transport and its impact on air composition at ground-level and downwind receptor locations. It is concluded that the measurements of air quality at Nottingham Centre, Stoke on Trent and Birmingham Centre on 2nd September 1998 are consistent with emissions from the sources identified in the Environment Agency report on this episode when allowance is made for oxidation of sulphur and nitrogen oxides within the plume. 3 refs., 9 figs., 9 tabs.

    We have investigated the crystal structure of deuterated lithium imide, Li{sub 2}ND, by means of neutron and X-ray diffraction. An order-disorder transition occurs near 360K. Below that temperature Li{sub 2}ND can be described to the same level of accuracy as a disordered cubic (Fd3-bar m) structure with partially occupied Li 32e sites or as a fully occupied orthorhombic (Ima2 or Imm2) structure. The high temperature phase is best characterized as disordered cubic (Fm3-bar m) with D atoms randomized over the 192l sites. Density functional theory calculations complement and support the diffraction analyses. We compare our findings in detail with previous studies.

    2013-08-01

    Near-infrared micro-imaging will not only provide the sample's spatial distribution information, but also the spectroscopic information of each pixel. In this thesis, it took the artificial sample of wheat flour and formaldehyde sodium sulfoxylate distribution given for example to research the data processing method for enhancing the quality of near-infrared micro-imaging. Near-infrared spectroscopic feature of wheat flour and formaldehyde sodium sulfoxylate being studied on, compare correlation imaging and 2nd derivative imaging were applied in the imaging processing of the near-infrared micro-image of the artificial sample. Furthermore, the two methods were combined, i.e. 2nd derivative compare correlation imaging was acquired. The result indicated that the difference of the correlation coefficients between the two substances, i.e. wheat flour and formaldehyde sodium sulfoxylate, and the reference spectrum has been increased from 0.001 in compare correlation image to 0.796 in 2nd derivative compare correlation image respectively, which enhances the imaging quality efficiently. This study will, to some extent, be of important reference significance to near-infrared micro-imaging method research of agricultural products and foods.

    2014-01-01

    Objectives:To evaluate the radiological and functional results of osteosynthesis with mini-plate and screws in metacarpal fractures. Methods:In our study43 patients who were operated between2009 and2012 were included. The patients were followed-up for(19.76±5.61) months.The mean age of patients was(31.11±7.81) years(7 females,36 males).The fracture types were oblique for19 patients, spiral for15 patients and transverse for9 patients.The patients were operated after a mean of3.4 d(range3 h-6 d) after the fracture had occurred.Patients were immobilized for2 weeks with a splint after surgery. Passive joint movements were started on the third days, and active joint movements were started in the second week.Rehabilitation of all patients was done in the same center with supervision of the same physiotherapist.The patients were assessed by total joint range of movement of the finger, grasping strength andQuick-DASH scores. Results:No significant differences were detected between fingers of the operated hand with same finger of the healthy hand according to total joint range of movement.Total joint range of movement values were measured perfect for38 patients, good for4 patients and medium for 1 patient.There were no significant differences with the corresponding finger on the opposite healthy side according to grasping strength.Soiling in the wound dressing was observed in1 patient but there was no active drainage.Soiling of the wound dressing disappeared after3-5 d of treatment with antimicrobial agent.Bone union was observed in all patients in a mean of6 weeks (range5-7 weeks).The time to return to work was(31.6±8.9) d after the surgical treatment of the fracture. Conclusions:Mini-plate and screws fixation of unstable metacarpal fractures produces anatomical reduction of fractures with stabilization that is rigid enough to allow early mobilization, thereby preventing stiffness and hence good functional results.

    1995-01-01

    Forty-two heifers and 38 steers sired by either Charolais (n = 47) or Salers (n = 33) from Bos indicus x Hereford dams were used to determine the effects of an anabolic agent on metacarpal characteristics and accompanying weight gain and carcass characteristics. Calves were blocked by sex and sire breed and either not implanted or implanted with Synovex-C within 45 d of birth, and with Synovex-S or -H at weaning and 84 and 169 d postweaning. Calves grazed oat pastures immediately after weaning for 169 d, after which calves received a feedlot diet for 124 d and were slaughtered. Live weight and hip height were recorded at initial implanting, weaning, d 84 and d 169 postweaning, and at approximately 28-d intervals during the feedlot period. Metacarpal and carcass characteristics were determined after slaughter. Metacarpals from implanted calves had greater medio-lateral axis (P grade and tended (P yield grade in heifers, but not in steers. Implanted calves tended (P < .08) to have a lower marbling score.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7601754

    2008-01-01

    The transition energies, wavelengths and dipole oscillator strengths of 1s22p-1s2nd (3≤n≤9) for Mn22+. ion are calculated. The fine structure splittings of 1s2nd (n ≤9) states for this ion are also evaluated. In calculating energy, the higher-order relativistic contribution is estimated under a hydrogenic approximation. The quantum defect of Rydberg series 1s2nd is determined according to the quantum defect theory. The results obtained in this paper excellently agree with the experi-mental data available in literatures.

  1. Active Control of Long Bridges Using Flaps

    Hansen, H. I.; Thoft-Christensen, Palle

    The main problem in designing ultra-long span suspension bridges is flutter. A solution to this problem might be to introduce an active flap control system to increase the flutter wind velocity. The investigated flap control system consists of flaps integrated in the bridge girder so each flap is...... different flap configurations for a bridge section model by using aerodynamic derivatives for a flat plate. The example shows that different flap configurations can either increase or decrease the flutter wind velocity. for optimal flap configurations flutter will not occur....

    A flap of the type that is movably connected to an aircraft wing to provide control of an aircraft in flight includes opposite ends, wherein at least a first opposite end includes a plurality of substantially rigid, laterally extending protrusions that are spaced apart to form a plurality of fluidly interconnected passageways. The passageways have openings adjacent to upper and lower sides of the flap, and the passageways include a plurality of bends such that high pressure fluid flows from a high pressure region to a low pressure region to provide a boundary condition that inhibits noise resulting from airflow around the end of the flap.

  3. Pathology of the distal condyles of the third metacarpal and third metatarsal bones of the horse

    This study examined material from Thoroughbred horses, the majority of which had been in race training, for evidence of pathology in the third metacarpal (McIII) and third metatarsal (MtIII) bones which might be related to the occurrence of distal condylar fractures. Whole bone samples were studied and documented by macrophotography prior to macroradiography and computed tomographic (CT) imaging. Microradiographs were made from 100 microm thick mediolateral sections cut perpendicular to the dorsal and palmar/plantar articular surfaces of distal condylar regions of McIII and MtIII. Blocks were prepared for morphological imaging using the backscattered electron mode of scanning electron microscopy (BSE SEM). Linear defects in mineralised articular cartilage and subchondral bone were found in the palmar/plantar aspects of the condylar grooves adjacent to the sagittal ridge. These were closely related to the pattern of densification of the subchondral bone and were associated with intense focal remodelling of the immediately adjacent and subjacent bone. Parasagittal fractures of the condyles originated in similar defects. A unifying hypothesis for the aetiopathogenesis of these fractures is presented

  4. Incomplete longitudinal fracture of the proximal palmar cortex of the third metacarpal bone in horses

    Seven horses, 2 to 4 years of age, were examined because of moderate-to-severe forelimb lameness, mild effusion of the middle carpal joint (3 horses), and pain on palpation of the origin of the suspensory ligament (4 horses). The lameness was abolished by anesthetic infiltration of the middle carpal joint in six horses. In four of them, a high palmar nerve block also abolished the lameness. A linear radiolucency in the proximal end of the third metacarpal bone (McIII) was interpreted as an incomplete longitudinal fracture. In one horse, distinct intramedullary sclerosis limited to the palmar cortex was indicative of an incomplete fracture confined to the palmar cortex. No osteoproliferative lesions were identified on the dorsal cortex of any of the horses. Surgical treatment with cortical screws in lag fashion accompanied by a rest period was successful in one horse. In four horses, rest for at least 3 months resulted in clinical soundness. In two horses, a shorter rest period resulted in recurrence of the lameness even though the horses were sound when put back into training. Careful clinical and radiographic examinations helped differentiate incomplete longitudinal fractures from lesions involving the carpus and proximal aspect of the suspensory ligament

  5. Nuclear scintigraphic evaluation of third metacarpal and metatarsal bone fractures in three horses

    Nuclear scintigraphy was used to evaluate healing of third metacarpal bone (MC III) fractures in 2 horses (horses 1 and 2) and a third metatarsal bone fracture in 1 horse (horse 3) after stabilization of each fracture with 2 broad dynamic compression plates. In horse 1, the fracture had uniform uptake of 99mTc methylene diphosphonate on days 1, 15, and 30 after surgery. The fracture healed, and the horse was discharged from the clinic on day 52. In horse 2, a 6-cm photopenic region (ie, area of low radioactivity) was seen over the diaphysis of MC III on day 3. The region persisted and became more distinct by day 32. The diaphysis of MC III sequestered, and horse 2 was euthanatized on day 44. In horse 3, vascularity was seen bridging the fracture on day 5, with a 3-cm photopenic region over the dorsal diaphysis of the third metatarsal bone. By days 18 and 32, uptake of 99mTc methylene diphosphonate in the region had increased, indicating vascularization of the site. the fracture healed, and horse 3 was discharged from the clinic on day 47. Our findings indicated that serial nuclear scintigraphy can be used to evaluate fracture vascularization after surgery in horses

  6. Comparison of radiogrammetrical metacarpal indices in children and reference data from the First Zurich Longitudinal Study

    A number of radiogrammetrical metacarpal indices are in use, some of which have been adapted for children. The purpose of this study was to compare four known indices - bone mineral density (BMD), relative cortical area, Exton-Smith index, bending breaking resistance index - and the more recently defined pediatric bone index (PBI) according to the two criteria of minimum height dependence and minimum variability in children of equal bone age. A total of 3,121 left-hand radiographs from 231 healthy Caucasian children ranging in age from 3 to 19 years old were analysed using BoneXpert registered, a programme for automatic analysis of hand radiographs and assessment of bone age. Dependence on height for chronological age or bone age and the mean relative standard deviation were lowest in the PBI for both genders pooled. The differences in height dependence were statistically significant and are shown to be clinically relevant. Reference data for PBI are presented. PBI may be a better indicator than BMD for bone health in children; however, verification in a clinical group is needed. (orig.)

    2008-01-01

    The transition energies, wavelengths and dipole oscillator strengths of 1s22p-1s2nd (3 ≤ n ≤ 9) for Cr21+ ion are calculated. The fine structure splittings of 1s2nd (n ≤ 9) states for this ion are also calculated. In calculating energy, we have estimated the higher-order relativistic contribution under a hydrogenic approximation. The quantum defect of Rydberg series 1s2nd is determined according to the quantum defect theory. The results obtained in this paper excellently agree with the experimental data available in the literature. Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from initial state 1s22p to highly excited 1s2nd states (n ≥ 10) and the oscillator strength density corresponding to the bound-free transitions are obtained.

  10. Systems Engineering Approach to Technology Integration for NASA's 2nd Generation Reusable Launch Vehicle

    Thomas, Dale; Smith, Charles; Thomas, Leann; Kittredge, Sheryl

    2002-01-01

    The overall goal of the 2nd Generation RLV Program is to substantially reduce technical and business risks associated with developing a new class of reusable launch vehicles. NASA's specific goals are to improve the safety of a 2nd-generation system by 2 orders of magnitude - equivalent to a crew risk of 1-in-10,000 missions - and decrease the cost tenfold, to approximately $1,000 per pound of payload launched. Architecture definition is being conducted in parallel with the maturating of key technologies specifically identified to improve safety and reliability, while reducing operational costs. An architecture broadly includes an Earth-to-orbit reusable launch vehicle, on-orbit transfer vehicles and upper stages, mission planning, ground and flight operations, and support infrastructure, both on the ground and in orbit. The systems engineering approach ensures that the technologies developed - such as lightweight structures, long-life rocket engines, reliable crew escape, and robust thermal protection systems - will synergistically integrate into the optimum vehicle. To best direct technology development decisions, analytical models are employed to accurately predict the benefits of each technology toward potential space transportation architectures as well as the risks associated with each technology. Rigorous systems analysis provides the foundation for assessing progress toward safety and cost goals. The systems engineering review process factors in comprehensive budget estimates, detailed project schedules, and business and performance plans, against the goals of safety, reliability, and cost, in addition to overall technical feasibility. This approach forms the basis for investment decisions in the 2nd Generation RLV Program's risk-reduction activities. Through this process, NASA will continually refine its specialized needs and identify where Defense and commercial requirements overlap those of civil missions.

  11. Application to non-destructive assay of 2nd layer tail cylinder at Rokkasho Enrichment plant

    International Atomic Energy Agency (IAEA) safeguards criteria 93+2 requirement stipulates that depleted uranium under the single C/S (Metal or Camera) is re-verified with 10% coverage (β=0.9) once a year, normally during physical inventory verification. In order to maintain the continuity of knowledge, the entire depleted uranium cylinders transferred from the processing area are sealed by inspectorates (the state and the IAEA) after sufficient verification with 50% coverage (β=0.5). At Rokkasho Enrichment plant, the depleted uranium cylinder (0.2∼0.3% enrichment of tail cylinder centrifuged by cascade) separated at the processing area is stored in the cylinder storage. The 2nd layer tail cylinder pile-up has been adopted for efficient-use of the storage; one block is comprised of four cylinders on the lower, three on the upper. The capacity of the specific cylinder crane is limited to as low as height of the upper cylinder. Current lifter with germanium detector is applied to the lower cylinder. However, it is highly possible that inspectorate selects random for the upper tail cylinder at the physical inventory verification. Therefore, at the verification, the operators corporate to lift down the 2nd layer tail cylinder to ground floor so that inspectorate is able to verify it. The Nuclear Material Control Center (NMCC) has designed and manufactured the specific detector lifter capable of the 2nd layer measurement and the potable detector's collimator. Afterwards, we conducted a site test in the plant and inspection efficiency and reduced operator's burden. (author)

  3. The ratio of 2nd to 4th digit length: a new predictor of disease predisposition?

    Manning, J T; Bundred, P E

    2000-05-01

    The ratio between the length of the 2nd and 4th digits is: (a) fixed in utero; (b) lower in men than in women; (c) negatively related to testosterone and sperm counts; and (d) positively related to oestrogen concentrations. Prenatal levels of testosterone and oestrogen have been implicated in infertility, autism, dyslexia, migraine, stammering, immune dysfunction, myocardial infarction and breast cancer. We suggest that 2D:4D ratio is predictive of these diseases and may be used in diagnosis, prognosis and in early life-style interventions which may delay the onset of disease or facilitate its early detection.

    Weigel, M; Friese, K; Schmitt, W; Strittmatter, H J; Melchert, F

    1992-12-01

    Superinfected subchorionic haematomas are a rare septic focus in the 2nd trimenon. Symptoms being unspecific, the diagnosis has to be made by exclusion, in most cases. As the changes of a successful treatment of the manifest infection is poor, antibiotic prophylaxis as well as close laboratory controls and early antibiotic therapy should be discussed after sonographic diagnosis of an intrauterine haematoma. Two of our three patients reported on having suffered a miscarriage; only one pregnancy could be maintained after spontaneous depletion of the infected haemorrhage. PMID:1490559

  18. Modified osteomyocutaneous iliac crest flaps transplantation.

    Liu, Jun; Song, Dajiang; Li, Jinsong; Xu, Jian; Lv, Hongbin

    2015-04-01

    The paper aims to improve the operative technique of osteomyocutaneous iliac crest flap harvesting, further minimise morbidity of donor site, and improve the effect of recipient site reconstruction. From March 2005 to March 2011, 55 cases of osteomyocutaneous iliac crest flap harvested by different methods were performed to reconstruct the defects of the extremities. Twenty-nine cases were reconstructed with a traditional deep circumflex iliac artery osteomusculocutaneous flap. Twenty-six cases were repaired with modified osteomyocutaneous iliac crest flaps. In 29 cases with a traditional DCIA osteomusculocutaneous flap, two cases showed the injured lateral femoral cutaneous nerve. Flapnecrosis was significant in two cases. Arterial compromise occurred in one case 5 days after operation completion and led to flap failure. Three flaps developed postoperative venous congestion, but only one flap received re-exploration. In the other two cases, some stitches were removed for decompression. All three flaps survived. In two cases, marginal flap necrosis occurred, but no secondary skin grafting was required. In 26 cases with modified flap transplantation, one case showed the injured lateral femoral cutaneous nerve. All flaps survived totally. Osseous integration was achieved in all 55 cases in 3 ∼ 9 months after operation. The modified osteomyocutaneous iliac crest flap technique enhances flap safety, provides the additional advantages of reducing donor-site morbidity, and improves the recipient-site contour.

  20. A novel 2nd-order bandpass MFSS filter with miniaturized structure

    C. Y. Fang

    2015-08-01

    Full Text Available In order to effectively obtain a miniaturized structure and good filtering properties, we propose a novel 2nd-order bandpass metamaterial frequency selective surface (MFSS filter which contains two capacitive layers and one inductive layer, where there are multi-loop metallic patches as shunt capacitor C and planar wire grids as series inductor L respectively. Unlike the traditional operation way—the tuned elements used in resonant surface approximately equal to one wavelength in circumference and the structure thickness with a spacing of a quarter wavelength apart, by changing the value of L and C and matching multilayer dielectric to adjust the LC coupling resonance and the resonance impedance respectively, the proposed MFSS filter can achieves a miniatured structure with ideal bandpass properties. Measurement results of the fabricated prototype of the bandpass filter (BPF indicate that the dimension of the tuned element on resonant surface is approximately 0.025 wavelength, i.e., 0.025λ. At the same time, the filter has the stable center frequency of f0 = 1.53GHz and the transmittance of T ⩾ 96.3% and high Q-value for the TE/TM wave polarization at various incidence angles. The novel 2nd-order bandpass MFSS filter with miniaturized structure not only can decrease structure dimension, but also has a wide range of applications to microwave and infrared band.

  1. Editorial: 2nd Special Issue on behavior change, health, and health disparities.

    Higgins, Stephen T

    2015-11-01

    This Special Issue of Preventive Medicine (PM) is the 2nd that we have organized on behavior change, health, and health disparities. This is a topic of fundamental importance to improving population health in the U.S. and other industrialized countries that are trying to more effectively manage chronic health conditions. There is broad scientific consensus that personal behavior patterns such as cigarette smoking, other substance abuse, and physical inactivity/obesity are among the most important modifiable causes of chronic disease and its adverse impacts on population health. As such behavior change needs to be a key component of improving population health. There is also broad agreement that while these problems extend across socioeconomic strata, they are overrepresented among more economically disadvantaged populations and contribute directly to the growing problem of health disparities. Hence, behavior change represents an essential step in curtailing that unsettling problem as well. In this 2nd Special Issue, we devote considerable space to the current U.S. prescription opioid addiction epidemic, a crisis that was not addressed in the prior Special Issue. We also continue to devote attention to the two largest contributors to preventable disease and premature death, cigarette smoking and physical inactivity/obesity as well as risks of co-occurrence of these unhealthy behavior patterns.

    Leber's hereditary optic neuropathy (LHON) is a mitochondrially inherited disease leading to blindness. A mitochondrial DNA point mutation at the 11778 nucleotide site of the NADH dehydrogenase subunit 4 (ND4) gene is the most common cause. The aim of this study was to evaluate the efficacy and safety of a recombinant adeno-associated virus 2 (AAV2) carrying ND4 (rAAV2-ND4) in LHON patients carrying the G11778A mutation. Nine patients were administered rAAV2-ND4 by intravitreal injection to one eye and then followed for 9 months. Ophthalmologic examinations of visual acuity, visual field, and optical coherence tomography were performed. Physical examinations included routine blood and urine. The visual acuity of the injected eyes of six patients improved by at least 0.3 log MAR after 9 months of follow-up. In these six patients, the visual field was enlarged but the retinal nerve fibre layer remained relatively stable. No other outcome measure was significantly changed. None of the nine patients had local or systemic adverse events related to the vector during the 9-month follow-up period. These findings support the feasible use of gene therapy for LHON.

  3. Scoping analysis of the Advanced Test Reactor using SN2ND

    Wolters, E.; Smith, M. (NE NEAMS PROGRAM); ( SC)

    2012-07-26

    A detailed set of calculations was carried out for the Advanced Test Reactor (ATR) using the SN2ND solver of the UNIC code which is part of the SHARP multi-physics code being developed under the Nuclear Energy Advanced Modeling and Simulation (NEAMS) program in DOE-NE. The primary motivation of this work is to assess whether high fidelity deterministic transport codes can tackle coupled dynamics simulations of the ATR. The successful use of such codes in a coupled dynamics simulation can impact what experiments are performed and what power levels are permitted during those experiments at the ATR. The advantages of the SN2ND solver over comparable neutronics tools are its superior parallel performance and demonstrated accuracy on large scale homogeneous and heterogeneous reactor geometries. However, it should be noted that virtually no effort from this project was spent constructing a proper cross section generation methodology for the ATR usable in the SN2ND solver. While attempts were made to use cross section data derived from SCALE, the minimal number of compositional cross section sets were generated to be consistent with the reference Monte Carlo input specification. The accuracy of any deterministic transport solver is impacted by such an approach and clearly it causes substantial errors in this work. The reasoning behind this decision is justified given the overall funding dedicated to the task (two months) and the real focus of the work: can modern deterministic tools actually treat complex facilities like the ATR with heterogeneous geometry modeling. SN2ND has been demonstrated to solve problems with upwards of one trillion degrees of freedom which translates to tens of millions of finite elements, hundreds of angles, and hundreds of energy groups, resulting in a very high-fidelity model of the system unachievable by most deterministic transport codes today. A space-angle convergence study was conducted to determine the meshing and angular cubature

  5. Experimental Study of Wake / Flap Interaction Noise and the Reduction of Flap Side Edge Noise

    Hutcheson, Florence V.; Stead, Daniel J.; Plassman, Gerald E.

    2016-01-01

    The effects of the interaction of a wake with a half-span flap on radiated noise are examined. The incident wake is generated by bars of various widths and lengths or by a simplified landing gear model. Single microphone and phased array measurements are used to isolate the effects of the wake interaction on the noise radiating from the flap side edge and flap cove regions. The effects on noise of the wake generator's geometry and relative placement with respect to the flap are assessed. Placement of the wake generators upstream of the flap side edge is shown to lead to the reduction of flap side edge noise by introducing a velocity deficit and likely altering the instabilities in the flap side edge vortex system. Significant reduction in flap side edge noise is achieved with a bar positioned directly upstream of the flap side edge. The noise reduction benefit is seen to improve with increased bar width, length and proximity to the flap edge. Positioning of the landing gear model upstream of the flap side edge also leads to decreased flap side edge noise. In addition, flap cove noise levels are significantly lower than when the landing gear is positioned upstream of the flap mid-span. The impact of the local flow velocity on the noise radiating directly from the landing gear is discussed. The effects of the landing gear side-braces on flap side edge, flap cove and landing gear noise are shown.

  6. Free thin paraumbilical perforator-based flaps.

    Koshima, I; Moriguchi, T; Soeda, S; Tanaka, H; Umeda, N

    1992-07-01

    A free paraumbilical perforator-based flap fed by a muscle perforator from the inferior deep epigastric artery and with no muscle was used in 13 patients. Among them, a free thin paraumbilical perforator-based flap with a thin layer of fat, to protect the subdermal plexus of the vessels, was used in seven patients. The dominant pedicle perforator of this thin flap is usually located around the umbilicus and a large flap can be obtained. Its critical length-to-breath ratio is considered to be 4:3. The advantages of this flap are a long and large vascular pedicle, rare postoperative abdominal herniation, little bulkiness of the flap, and a relatively large skin territory. The disadvantages are technical difficulties in dissection of the perforator and anatomical variation in the location of the perforator. We believe this flap largely overcomes the problems of the conventional rectus abdominis musculocutaneous flap. PMID:1386718

  12. Nonlinear Dynamics of Memristor Based 2nd and 3rd Order Oscillators

    Talukdar, Abdul Hafiz

    2011-05-01

    Exceptional behaviours of Memristor are illustrated in Memristor based second order (Wien oscillator) and third order (phase shift oscillator) oscillator systems in this Thesis. Conventional concepts about sustained oscillation have been argued by demonstrating the possibility of sustained oscillation with oscillating resistance and dynamic poles. Mathematical models are also proposed for analysis and simulations have been presented to support the surprising characteristics of the Memristor based oscillator systems. This thesis also describes a comparative study among the Wien family oscillators with one Memristor. In case of phase shift oscillator, one Memristor and three Memristors systems are illustrated and compared to generalize the nonlinear dynamics observed for both 2nd order and 3rd order system. Detail explanations are provided with analytical models to simplify the unconventional properties of Memristor based oscillatory systems.

    In a few years, the second generation instruments of the Very Large Telescope Interferometer (VLTI) will routinely provide observations with 4 to 6 telescopes simultaneously. To reach their ultimate performance, they will need a fringe sensor capable to measure in real time the randomly varying optical paths differences. A collaboration between LAOG (PI institute), IAGL, OCA and GIPSA-Lab has proposed the Planar Optics Phase Sensor concept to ESO for the 2nd Generation Fringe Tracker. This concept is based on the integrated optics technologies, enabling the conception of extremely compact interferometric instruments naturally providing single-mode spatial filtering. It allows operations with 4 and 6 telescopes by measuring the fringes position thanks to a spectrally dispersed ABCD method. We present here the main analysis which led to the current concept as well as the expected on-sky performance and the proposed design.

  15. Tetragonal ZrO2:Nd3+ nanosphere: Combustion synthesis, luminescence and photoacoustic spectroscopy

    Gupta, Santosh K.; Chandrasekhar, D.; Kadam, R. M.

    2015-12-01

    Nanocrystalline ZrO2:Nd3+ was synthesised using gel-combustion method and characterized systematically using X-ray diffraction (XRD) and transmission electron microscopy (TEM). Through this route we can stabilize metastable tetragonal phase at 500 °C through addition of 1 mol % Nd3+ which is technologically more important. Optical characterization of the sample was done using photoluminescence (PL) and photoacoustic spectroscopy (PAS). PL studies shows an intense and optimum stimulated emission cross section of 1065 nm peak corresponding to 4F3/2 → 4I11/2 which and thus it can be a probable laser material. PAS is used to investigate electronic absorption of Nd3 in zirconia. Various covalency parameters like nephelauxetic ratio (β), covalency factor (b1/2) and Sinha parameter (δ) were evaluated for pure oxide powder and as well as for Nd3+ doped zirconia.

    International GNSS Service (IGS) has contributed to the International Terrestrial Reference Frame by reprocessing historic GPS network data and submitting Terrestrial Reference Frame solutions and Earth Rotation Parameters. For the 2nd reprocessing campaign, Analysis Centers (ACs) used up to 21 years of GPS observation data with daily integrations. IERS2010 conventions are applied to model the physical effects of the Earth. Total eight ACs have participated (7 Global solutions, and 2 Tide Gauge solutions) by reprocessing entire time series in a consistent way using the latest models and methodology. IGS combined daily SINEX TRF and EOP combinations have already been submitted to the IERS for ITRF2013. This presentation mainly focuses on the preliminary quality assessment of the reprocessed AC orbits. Quality of the orbit products are examined by examining the repeatability between daily AC satellite ephemeris. Power spectral analysis shows the background noise characteristics of each AC products, and its periodic behaviors.

  4. Boosting biogas yield of anaerobic digesters by utilizing concentrated molasses from 2nd generation bioethanol plant

    Sarker, Shiplu [Department of Renewable Energy, Faculty of Engineering and Science, University of Agder, Grimstad-4879 (Norway); Moeller, Henrik Bjarne [Department of Biosystems Engineering, Faculty of Science and Technology, Aarhus University, Research center Foulum, Blichers Alle, Post Box 50, Tjele-8830 (Denmark)

    2013-07-01

    Concentrated molasses (C5 molasses) from 2nd generation bioethanol plant has been investigated for enhancing productivity of manure based digesters. A batch study at mesophilic condition (35+- 1 deg C) showed the maximum methane yield from molasses as 286 LCH4/kgVS which was approximately 63% of the calculated theoretical yield. In addition to the batch study, co-digestion of molasses with cattle manure in a semi-continuously stirred reactor at thermophilic temperature (50+- 1 deg C) was also performed with a stepwise increase in molasses concentration. The results from this experiment revealed the maximum average biogas yield of 1.89 L/L/day when 23% VSmolasses was co-digested with cattle manure. However, digesters fed with more than 32% VSmolasses and with short adaptation period resulted in VFA accumulation and reduced methane productivity indicating that when using molasses as biogas booster this level should not be exceeded.

  5. Belief Functions: Theory and Applications - Proceedings of the 2nd International Conference on Belief Functions

    Masson, Marie-Hélène

    2012-01-01

    The theory of belief functions, also known as evidence theory or Dempster-Shafer theory, was first introduced by Arthur P. Dempster in the context of statistical inference, and was later developed by Glenn Shafer as a general framework for modeling epistemic uncertainty. These early contributions have been the starting points of many important developments, including the Transferable Belief Model and the Theory of Hints. The theory of belief functions is now well established as a general framework for reasoning with uncertainty, and has well understood connections to other frameworks such as probability, possibility and imprecise probability theories.   This volume contains the proceedings of the 2nd International Conference on Belief Functions that was held in Compiègne, France on 9-11 May 2012. It gathers 51 contributions describing recent developments both on theoretical issues (including approximation methods, combination rules, continuous belief functions, graphical models and independence concepts) an...

  6. A Perpendicular Biased 2nd Harmonic Cavity for the Fermilab Booster

    A perpendicular biased 2nd harmonic cavity is currently being designed for the Fermilab Booster. Its purpose cavity is to flatten the bucket at injection and thus change the longitudinal beam distribution so that space charge effects are decreased. It can also with transition crossing. The reason for the choice of perpendicular biasing over parallel biasing is that the Q of the cavity is much higher and thus allows the accelerating voltage to be a factor of two higher than a similar parallel biased cavity. This cavity will also provide a higher accelerating voltage per meter than the present folded transmission line cavity. However, this type of cavity presents technical challenges that need to be addressed. The two major issues are cooling of the garnet material from the effects of the RF and the cavity itself from eddy current heating because of the 15 Hz bias field ramp. This paper will address the technical challenge of preventing the garnet from overheating.

  10. Enabling the 2nd Generation in Space: Building Blocks for Large Scale Space Endeavours

    Barnhardt, D.; Garretson, P.; Will, P.

    Today the world operates within a "first generation" space industrial enterprise, i.e. all industry is on Earth, all value from space is from bits (data essentially), and the focus is Earth-centric, with very limited parts of our population and industry participating in space. We are limited in access, manoeuvring, on-orbit servicing, in-space power, in-space manufacturing and assembly. The transition to a "Starship culture" requires the Earth to progress to a "second generation" space industrial base, which implies the need to expand the economic sphere of activity of mankind outside of an Earth-centric zone and into CIS-lunar space and beyond, with an equal ability to tap the indigenous resources in space (energy, location, materials) that will contribute to an expanding space economy. Right now, there is no comfortable place for space applications that are not discovery science, exploration, military, or established earth bound services. For the most part, space applications leave out -- or at least leave nebulous, unconsolidated, and without a critical mass -- programs and development efforts for infrastructure, industrialization, space resources (survey and process maturation), non-traditional and persistent security situational awareness, and global utilities -- all of which, to a far greater extent than a discovery and exploration program, may help determine the elements of a 2nd generation space capability. We propose a focus to seed the pre-competitive research that will enable global industry to develop the necessary competencies that we currently lack to build large scale space structures on-orbit, that in turn would lay the foundation for long duration spacecraft travel (i.e. key technologies in access, manoeuvrability, etc.). This paper will posit a vision-to-reality for a step wise approach to the types of activities the US and global space providers could embark upon to lay the foundation for the 2nd generation of Earth in space.

  11. Efficient flapping flight of pterosaurs

    Strang, Karl Axel

    In the late eighteenth century, humans discovered the first pterosaur fossil remains and have been fascinated by their existence ever since. Pterosaurs exploited their membrane wings in a sophisticated manner for flight control and propulsion, and were likely the most efficient and effective flyers ever to inhabit our planet. The flapping gait is a complex combination of motions that sustains and propels an animal in the air. Because pterosaurs were so large with wingspans up to eleven meters, if they could have sustained flapping flight, they would have had to achieve high propulsive efficiencies. Identifying the wing motions that contribute the most to propulsive efficiency is key to understanding pterosaur flight, and therefore to shedding light on flapping flight in general and the design of efficient ornithopters. This study is based on published results for a very well-preserved specimen of Coloborhynchus robustus, for which the joints are well-known and thoroughly described in the literature. Simplifying assumptions are made to estimate the characteristics that can not be inferred directly from the fossil remains. For a given animal, maximizing efficiency is equivalent to minimizing power at a given thrust and speed. We therefore aim at finding the flapping gait, that is the joint motions, that minimize the required flapping power. The power is computed from the aerodynamic forces created during a given wing motion. We develop an unsteady three-dimensional code based on the vortex-lattice method, which correlates well with published results for unsteady motions of rectangular wings. In the aerodynamic model, the rigid pterosaur wing is defined by the position of the bones. In the aeroelastic model, we add the flexibility of the bones and of the wing membrane. The nonlinear structural behavior of the membrane is reduced to a linear modal decomposition, assuming small deflections about the reference wing geometry. The reference wing geometry is computed for

    This study aims to determine if the relative displacement between the extensor digitorum communis (EDC) tendon and its surrounding tissues can be used as an adhesion index (AI) for assessing adhesion in metacarpal fractures by comparing two clinical measures, namely single-digit-force and extensor lag (i.e., the difference between passive extension and full active extension). The Fisher–Tippett block-matching method and a Kalman-filter algorithm were used to determine the relative displacements in 39 healthy subjects and 8 patients with metacarpal fractures. A goniometer was used to measure the extensor lag, and a force sensor was used to measure the single-digit-force. Measurements were obtained twice for each patient to evaluate the performance of the AI in assessing the progress of rehabilitation. The Pearson correlation coefficient was calculated to quantify the various correlations between the AI, extensor lag, and single-digit-force. The results showed strong correlations between the AI and the extensor lag, the AI and the single-digit-force, and the extensor lag and the single-digit-force (r = 0.718, −0.849, and −0.741; P = 0.002, P AI in the patients gradually decreased after continuous rehabilitation, but remained higher than that of healthy participants.

  13. Bone morphometry and mineral contents of the distal part of the fractured third metacarpal bone in thoroughbred racehorses

    Most of the bone fractures in racehorses occur in the fore limb, especially in the metacarpal joint during the racing and training. The longitudinal fracture of the third metacarpal bone (Mc III) often occurs in the osteosclerotic and/or necrotic lesions in the distal part of the bone. To elucidate the endogenous factors of its fracture, soft radiograms of 4 fractured and 4 non-fractured control cases have been investigated morphometrically by a image analyzer. In addition, to analyze the quality of these bones, 20 elements of mineral contents in the crashed bones have been measured using a fluorescent X-ray analyzer. As the results, the osteosclerotic change was observed in both groups in the plantar side of the distal part of Mc III, however, no significant differences were found in the bone morphometry. No significant differences in the 19 elements of bone mineral were found except Fe. From these findings, the mechanism of the occurrence of the longitudinal fracture in the Mc III remains to be elucidated. In future, further work needs to be done with regard to the mechanical intensity and collagen disposition of the distal part of the Mc III

  14. Geochemical evidence of paleogeography and paleoclimate during deposition of the 2nd Member of Kongdian Formation in Kongnan area

    2007-01-01

    The 2nd Member of Kongdian Formation has been made up of a large number of oil shale and mudstone in the Kongnan aera of Huanghua depression around the Bohai Bay. In the Kongnan area, the lake basins were very large and deep during the deposition of the 2nd Member of Kongdian Formation. During that period,the lakes were sealed, uncommunieated with the sea water and the paleoclimate was very warm and wet in Kongnan area. Analyzing the content of the trace element and the rare earth element, carbon and oxygen isotope in the disquisition, The authors prove the two views correct.

  16. The possibility for use of venous flaps in plastic surgery

    The use of venous flaps is controversial. The mechanism of perfusion of venous flaps is still not fully understood. The research was conducted on 56 white rats. In our experimental work we studied two different models of venous flaps: pedicled venous flap (PVF) and pedicled arterialized venous flap (PAVF). Our results showed that postoperative congestion was present in all flaps. However 66.7% of all pedicled venous flaps and 100% of all pedicled arterialized venous flaps eventually survived. Histological examination revealed that postoperatively the blood flow in the skin of the pedicled arterialized venous flap became «re-reversed» again; there were no differences between mechanism of survival of venous flaps and other flaps. On the 7-14th day in the skin of all flaps were processes of neoangiogenesis and proliferation. Hence the best scenario for the clinical use of venous flaps unfolds when both revascularization and skin coverage are required

    Transition energies, wavelengths and dipole oscillator strengths of 1s22p - 1s2nd (3 ≤ n ≤ 9) for Fe23+ ion are calculated. The fine structure splittings of 1s2nd (n ≤ 9) states for this ion are also evaluated. The higher-order relativistic contribution to the energy is estimated under a hydrogenic approximation. The quantum defect of Rydberg series 1s2nd is determined according to the quantum defect theory. The energies of any highly excited states with (n ≥ 10) for this series can be reliably predicted using these quantum defects as input. The results in this paper excellently agree with the experimental data available in the literature. Combining the quantum defect theory with the discrete oscillator strengths, the discrete oscillator strengths for the transitions from same given initial state 1s22p to highly excited 1s2nd states (n ≥ 10) and the oscillator strength density corresponding to the bound-free transitions is obtained.

    Full Text Available On April 2nd, the Macedonian Scientific Society for Autism, for the fourth time organized an event on the occasion of the International Day of Persons with Autism. The event with cultural and artistic character was held at the Museum of the Macedonian Struggle under the motto “They are not alone, we are with them”. The huge number of citizens only confirmed the motto. It seemed that the hall of the Museum of the Macedonian Struggle is too small for the warm hearts of the audience. More than 300 guests were present in the hall, among which there were children with autism and their families, prominent professors, doctors, special educators and rehabilitators, psychologists, students and other citizens with glad heart and will who decided to enrich the event with their presence. The event was opened by the violinist Plamenka Trajkovska, which performed one song. After her, the President of the Macedonian Scientific Society for Autism, PhD. Vladimir Trajkovski delivered his speech. The professor told the parents of autistic children, who were present in large number, not to lose hope, to fight for their children, and that the Macedonian Scientific Society for Autism will provide tremendous support and assistance in this struggle.

  8. Deaf-mute teaching during the Spanish 2nd Republic period. A historical view

    Alfredo ALCINA MADUEÑO

    2011-07-01

    Full Text Available Deaf-mute teaching during the Spanish 2nd Republic period is an issue which has never been studied in depth consideration and some of its aspects have been not even touched by any research. We could say that deaf-mute education is granted with the characteristics found in general education, at least regarding this specific stage, mainly: economic and budget thoughtful following effort by the governments, methodological renovation, modernization of the educative system, spreading of the school-net, teachers’ formation, etcetera. However it is true that we can fin a very strict-stated idiosyncrasy, which sometimes turns out to be even controversial, not only due to the opposition of different political parties in power during different 2-years periods (31/37 and 34/35, but also because of the republican-socialist governments decisions regarding educative policy. The Republican legacy consists actually much more in documentary facts than in actual realisations, and will have much more application within that political regime that follows and annihilates the Republic than within the period of the Republic itself. The consideration of primary sources (both legal and documental is the base that supports the final conclusions that are provided by means of this exposition.

  9. Proceedings of the 2nd CSNI Specialist Meeting on Simulators and Plant Analysers

    The safe utilisation of nuclear power plants requires the availability of different computerised tools for analysing the plant behaviour and training the plant personnel. These can be grouped into three categories: accident analysis codes, plant analysers and training simulators. The safety analysis of nuclear power plants has traditionally been limited to the worst accident cases expected for the specific plant design. Many accident analysis codes have been developed for different plant types. The scope of the analyses has continuously expanded. The plant analysers are now emerging tools intended for extensive analysis of the plant behaviour using a best estimate model for the whole plant including the reactor and full thermodynamic process, both combined with automation and electrical systems. The comprehensive model is also supported by good visualisation tools. Training simulators with real time plant model are tools for training the plant operators to run the plant. Modern training simulators have also features supporting visualisation of the important phenomena occurring in the plant during transients. The 2nd CSNI Specialist Meeting on Simulators and Plant Analysers in Espoo attracted some 90 participants from 17 countries. A total of 49 invited papers were presented in the meeting in addition to 7 simulator system demonstrations. Ample time was reserved for the presentations and informal discussions during the four meeting days. (orig.)

  10. Severe weather phenomena: SQUALL LINES The case of July 2nd 2009

    Paraschivescu, Mihnea; Tanase, Adrian

    2010-05-01

    The wind intensity plays an important role, among the dangerous meteorological phenomena, to produce negative effects on the economy and the social activities, particularly when the wind is about to turn into a storm. During the past years one can notice an increase of wind frequency and intensity due to climate changes and, consequently, as a result of the extreme meteorological phenomena not only on a planetary level but also on a regional one. Although dangerous meteorological phenomena cannot be avoided, since they are natural, nevertheless they can be anticipated and decision making institutions and mass media can be informed. This is the reason why, in this paper, we set out to identify the synoptic conditions that led to the occurrence of the severe storm case in Bucharest on July 2nd, 2009, as well as the matrices that generate such cases. At the same time we sought to identify some indications evidence especially from radar data so as to lead to the improvement of the time interval between the nowcasting warning and the actual occurrence of the phenomenon.
