    The Savannah River Plant (SRP) has maintained a number of sites used for land disposal of various waste materials. The General Separations Area at SRP, located between the Upper Three Runs and Four Mile Creeks, has served as an active area for waste storage for about thirty years. The Tuscaloosa aquifer, which lies beneath the General Separations Area, is a water source for SRP and the surrounding area. The isolation of the Tuscaloosa aquifer has been maintained by an upward hydraulic gradient from the Tuscaloosa aquifer to the overlying Congaree aquifer. This upward gradient is referred to as a hydraulic head reversal in the General Separations Area, i.e., hydraulic heads in the upper Tuscaloosa are higher than hydraulic heads in the Congaree. This head reversal has declined in recent years due to increased groundwater pumping in the upper and lower Tuscaloosa formations. The objective of this investigation is to assess the effects of pumping within the General Separations Area on the Congaree/upper Tuscaloosa head reversal. Methods of maintaining future Tuscaloosa aquifer isolation through the optimization of groundwater withdrawal location and rate were studied. Steady-state and transient groundwater flow models were used to characterize past and potential future groundwater conditions. Future groundwater conditions were simulated for a variety of pumping scenarios.

    2011-01-01

    For the largest producing natural gas fields in the onshore Gulf of Mexico Basin, the relation between temperature versus depth was investigated. Prolific natural gas reservoirs with the highest temperatures were found in the Upper Cretaceous downdip Tuscaloosa trend in Louisiana. Temperature and production trends from the deepest field, Judge Digby field, in Pointe Coupe Parish, Louisiana, were investigated to characterize the environment of natural gas in the downdip Tuscaloosa trend. The average production depth in the Judge Digby field is approximately 22,000 ft. Temperatures as high as 400 degrees F are typically found at depth in Judge Digby field and are anomalously low when compared to temperature trends extrapolated to similar depths regionally. At 22,000 ft, the minimum and maximum temperatures for all reservoirs in Gulf Coast producing gas fields are 330 and 550 degrees F, respectively; the average temperature is 430 degrees F. The relatively depressed geothermal gradients in the Judge Digby field may be due to high rates of sediment preservation, which may have delayed the thermal equilibration of the sediment package with respect to the surrounding rock. Analyzing burial history and thermal maturation indicates that the deep Tuscaloosa trend in the Judge Digby field is currently in the gas generation window. Using temperature trends as an exploration tool may have important implications for undiscovered hydrocarbons at greater depths in currently producing reservoirs, and for settings that are geologically analogous to the Judge Digby fiel

    2000-01-01

    Suppose F is a field of characteristic not 2 and F* its multiplicative group.Let T* n (F) be the multiplicative group of invertible upper triangular n × n matrices over F and ST±n(F) its subgroup {(aij) ∈ T * n(F)|aii = +1,i}.This paper proves that f:T * n(F) → T * n(F) is a group automorphism if and only if there exist a matrix Q in T * n(F) and a field automorphism σ of F such that either σ -1 f(A) = ψ(A)QAσQ-1,A = (aij) ∈ T * n(F) or f(A) = ψ(A-1)Q[J(Aσ)-TJ]Q-1,A =(aij) ∈ T * n(F),where Aσ = (σ(aij)),A-T is the transpose inverse of A,J = n∑i=1 Ei n+1-i,and ψ :i=1 T * n(F) → F* is a homomorphism which satisfies {ψ(xIn)σ(x)|x ∈ F*} = F* and {x ∈F*|ψ(xIn)σ(x) = 1} = {1}.Simultaneously,they also determine the automorphisms of ST±n(F).

    Stokes, Courtney; Senkbeil, Jason C

    2017-01-01

    This paper represents one of the first attempts to analyse the many ways in which Facebook and Twitter were used during a tornado disaster. Comparisons between five randomly selected campus samples and a city of Tuscaloosa, Alabama, sample revealed that campus samples used Facebook and Twitter significantly more both before and after the tornado, but Facebook usage was not significantly different after the event. Furthermore, differences in social media usage and other forms of communication before the tornado were found for age, education, and years lived in Tuscaloosa. Generally, age and education were inversely proportionate to social media usage. Influences on shelter-seeking actions varied between social media users and three random samples of non-social media users; however, it appears that social media respondents were likely to be using a smartphone simultaneously to access warning polygon information, to receive text message alerts, and to listen or respond to environmental cues.

    Kanter, Robert K

    2012-09-01

    To empirically describe the integration of pediatric disaster services into regional systems of care after the April 27, 2011, tornado in Tuscaloosa, Alabama, a community with no pediatric emergency department or pediatric intensive care unit and few pediatric subspecialists. Data were obtained in interviews with key informants including professional staff and managers from public health and emergency management agencies, prehospital emergency medical services, fire departments, hospital nurses, physicians, and the trauma program coordinator. A single hospital in Tuscaloosa served 800 patients on the night of the tornado. More than 100 of these patients were children, including more than 20 with critical injuries. Many children were unaccompanied and unidentified on arrival. Resuscitation and stabilization were performed by nonpediatric prehospital and emergency department staff. More than 20 children were secondarily transported to the nearest children's hospital an hour's drive away under the care of nonpediatric local emergency medical services providers. No preventable adverse events were identified in the resuscitation and secondary transport phases of care. Stockpiled supplies and equipment were adequate to serve the needs of the disaster victims, including the children. Essential aspects of preparation include pediatric-specific clinical skills, supplies and equipment, operational disaster plans, and interagency practice embedded in everyday work. Opportunities for improvement identified include more timely response to warnings, improved practices for identifying unaccompanied children, and enhanced child safety in shelters. Successful responses depended on integration of pediatric services into regional systems of care. Copyright © 2012 Mosby, Inc. All rights reserved.

  12. Classification of upper motives of algebraic groups of inner type A_n

    CERN Document Server

    De Clercq, Charles

    2011-01-01

    Let A, A' be two central simple algebras over a field F and \\mathbb{F} be a finite field of characteristic p. We prove that the upper indecomposable direct summands of the motives of two anisotropic varieties of flags of right ideals X(d_1,...,d_k;A) and X(d'_1,...,d'_s;A') with coefficients in \\mathbb{F} are isomorphic if and only if the p-adic valuations of gcd(d_1,...,d_k) and gcd(d'_1,..,d'_s) are equal and the classes of the p-primary components A_p and A'_p of A and A' generate the same group in the Brauer group of F. This result leads to a surprising dichotomy between upper motives of absolutely simple adjoint algebraic groups of inner type A_n

    The central Fujian Province, situated on the juncture of paleo-uplift of Wuyishan, Yongmei Late Paleozoic depression and the eastern volcanic rift-faulting zone, is mainly composed of the outcropped metamorphic basements in the Middle-Late and Early Proterozoic, which constitute two upper and lower giant thick formations of Precambrian volcanic-sedimentary cycles, respectively. The formation of Dongyan Group is an important Middle-Upper Proterozoic component, and the Dongyan Group is directly related to massive sulfide deposit in this area. In recent years, plenty of lead, zinc, copper, silver and gold deposits have been found and explored. The Precambrian paleorift setting of the central Fujian Province served as a favorite metallogenic background for the formation of large- and superlarge-scale volcanic massive sulfide (VMS) lead and zinc polymetal deposits. The Dongyan Group consists chiefly of a set of ancient volcanic sedimentary formations that are composed mainly of greenschist. Its major lithologic types comprise greenschist, marble, quartzite and granofels class including various components. The metamorphic rocks of Dongyan Group are the main composition of Middle and Upper Proterozoic volcanic-sedimentary cycle. The original rock of Dongyan Group, a stable rock association, is volcanic sedimentation and normal marine sedimentation. But the original volcanic rocks, basic and acid, are bimodal. The volcanic rocks were formed in the extensional continental rift setting.

    General Motors (GM) is studying the feasibility of aquifer thermal energy storage (ATES) for air conditioning at their Harrison Division plant located in Tuscaloosa, Alabama. Pacific Northwest Laboratory (PNL) has assisted in this effort by conducting field tests to measure the hydraulic properties of the proposed ATES well field, which will be within the unconfined aquifer and adjacent to the GM plant. Results showed that in the vicinity of the test well, transmissivity was 2000 ft{sup 2}/d, effective aquifer thickness was 50 ft, effective porosity was 6.2%, hydraulic gradient was 0.005, and seepage velocity was 3.2 ft/d. A second test series at a newly constructed well was expanded to include measuring specific capacity and investigating the vertical distribution of flow within the aquifer. Specific objectives were to determine the injection capacity of the aquifer and to examine efficiency of the well design. Transmissivity was 2300 to 2600 ft{sup 2}/d, effective aquifer thickness was 58 ft, effective porosity was 6.0 to 8.0%, hydraulic gradient was 0.0047, and seepage velocity was 3.1 to 2.7 ft/d. Injection capacity, based on a step-injection test, was approximately 17 gpm/ft and was independent of flow rate within the experimental range 90 to 338 gpm. Maximum hydraulic conductivity occurred within the uppermost 20 ft of saturated sediments, which consisted of well-sorted sand. Below the sand, sorting was progressively poorer with depth, and hydraulic conductivity decreased smoothly. At the base of the aquifer, hydraulic conductivity was less than 10% of that of the uppermost 20 ft. 7 refs., 10 figs.

    The General Motors corporation is studying the feasibility of aquifer thermal energy storage (ATES) for cooling purposes at its Harrison Division plant Tuscaloosa, Alabama. To determine the characteristics of the aquifer underlying the plant, the Pacific Northwest Laboratory (PNL) gathered information about the environment of the aquifer and conducted tests to determine the aquifer's transmissivity and flow. From these tests, calculated estimates of ground-water velocity and flow direction were made. Nine wells were drilled at the plant site. Apparently, a confining bed of clay locally divides the aquifer into two separate units, one confined and one unconfined. An initial attempt to determine the hydraulic gradient in the aquifer was complicated by the resulting discrepancies in water levels among wells as well as by offsite pumping of the same aquifer; however, an estimate of the direction and magnitude of the hydraulic gradient for the composite aquifer was made. Two other types of tests successfully provided data for ground-water flow velocity for ATES design. A constant-discharge and recovery test was conducted to determine transmissivity (hydraulic conductivity). A single-well tracer test was also conducted, and results of the two tests were used conjunctively to estimate ground-water flow velocity. Transmissivity was found to be approximately 2000 ft{sup 2}/day at two wells closet to the pumped well in the parking lot of the General Motors plant. The average hydraulic conductivity is assumed to be approximately 40 ft/day in the same vicinity. The calculated ground-water velocity is approximately 3.25 ft/day with an effective porosity of approximately 6%. 5 refs., 7 figs., 3 tabs.

    Effective management of upper gastrointestinal bleeding (UGIB) relies on the application of clinical risk scores. The validation of risk scores has to date focused mainly on nonvariceal UGIB groups. We aimed to evaluate our clinical and endoscopic management of UGIB, and to validate existing risk scores for a mixed patient population with a high percentage of variceal bleeds. Analysis included UGIB patients presenting consecutively to a tertiary referral university hospital. All patients had been admitted by our emergency department and had undergone upper gastrointestinal endoscopy. Clinical, biochemical and endoscopic data were recorded. Clinical and complete Rockall and Blatchford risk scores were calculated for all patients and statistical analysis was carried out by a multiple logistical regression model. A total of 21% of patients had variceal bleeds. There was considerable heterogeneity between groups with the variceal group having more comorbidities (P=0.003), lower haemoglobin (P=0.003) and lower systolic blood pressure (P=0.013) at presentation. This translated to higher risk scores (Pbleeding or mortality. However, no patient with a Blatchford score of 0 had an adverse clinical outcome. Postendoscopic Rockall score can be used as a predictor of outcome for mixed UGIB groups. Although Blatchford score did not predict outcome in our study, at a 0 level it does appear to be a safe triage tool for pre-endoscopic identification of patients with variceal bleeds, even where there is no known history of liver disease.

    Manual wheelchair users have a high risk of injury to the upper extremities. Recent studies have focused on kinematic and kinetic analyses of manual wheelchair propulsion in order to understand the physical demands on wheelchair users. The purpose of this study was to investigate upper limb joint motion by using a motion capture system and a dynamometer with two different groups of wheelchair users propelling their wheelchairs at different speeds under different load conditions. The variations in the contact time, release time, and linear velocity of the experienced group were all larger than they were in the novice group. The propulsion angles of the experienced users were larger than those of the novices under all conditions. The variances in the propulsion force (both radial and tangential) of the experienced users were larger than those of the novices. The shoulder joint moment had the largest variance with the conditions, followed by the wrist joint moment and the elbow joint moment. The variance of the maximum shoulder joint moment was over four times the variance of the maximum wrist joint moment and eight times the maximum elbow joint moment. The maximum joint moments increased significantly as the speed and load increased in both groups. Quick and significant manipulation ability based on environmental changes is considered an important factor in efficient propulsion. This efficiency was confirmed from the propulsion power results. Sophisticated strategies for efficient manual wheelchair propulsion could be understood by observation of the physical responses of each upper limb joint to changes in load and speed. We expect that the findings of this study will be utilized for designing a rehabilitation program to reduce injuries.

    Schwannoma is a benign, encapsulated perineural tumour originating from the schwann cells of the neural sheath of peripheral motor and sensory nerves. It may develop at any age but is extremely rare in paediatric age group. The tumour is frequently located on the head and neck region, the tongue being the most common site followed by the palate, floor of mouth, buccal mucosa, lips and jaws. Schwannomas rarely occur in the lip area and it is exceedingly rare in the upper lip. The lesion is usually solitary but can be multiple when associated with neurofibromatosis. The diagnosis is usually confirmed after biopsy and anti-S100 protein immuno-histochemical staining is usually used to identify the tumour. In the present study the patient was a 14-year-old young girl with the schwannoma on the upper lip which is probably the third such case in a paediatric age group being reported and was excised without any recurrence at 2 year after excision.

    Models of supersymmetric grand unified theories based on SU(5)_GUT \\times U(N)_H gauge group (N = 2,3) have a symmetry that guarantees light two Higgs doublets and absence of dimension-five proton decay operators. We analysed the proton decay induced by gauge-boson exchange in the models. Upper bounds of proton life-time are obtained; \\tau(p\\to \\pi^0e^+) \\lsim 6.0 \\times 10^{33} yrs. in the SU(5)_GUT \\times U(2)_H model and \\tau(p\\to \\pi^0e^+) \\lsim 5.3 \\times 10^{35} yrs. in the SU(5)_GUT \\times U(3)_H model. Various uncertainties in the predictions are also discussed.

    1993-01-01

    Paleontological evidence from the Upper Triassic Chatham Group in the three subbasins of the Deep River basin (North Carolina, USA) supports a significant revision of the ages assigned to most of this non-marine continental sedimentary sequence. This study confirms an early(?) or mid-Carnian age in the Sanford subbasin for the base of the Pekin Formation, the lowest unit of the Chatham Group. However, diagnostic late Carnian palynomorphs have been recovered from coals in the lower part of the Cumnock Formation in the Sanford subbasin, and from a sample of the Cumnock Formation equivalent in the Wadesboro subbasin. Plant megafossils and fossil verebrates from rocks in the Sanford subbasin also support a late Carnian age for the Cumnock Formation and its equivalents. The overlying Sanford Formation, which has not yet been dated paleontologically, probably includes beds of Norian age, as over 1000 m of strata may be present between the Cumnock Formation coals (dated here as late Carnian) and the top of the Sanford Formation. This chronostratigraphic interval appears similar to, but slightly longer than, that preserved in the Dan River-Danville and Davie County basins 100 km to the northwest. Our evidence, therefore, indicates that the Chatham Group was deposited over a much longer time interval [early(?) to mid-Carnian through early Norian] than previously was believed. ?? 1993.

    A highly diversified, advanced and exceptionally well preserved microfossil assemblage, dominated by a planktic community,has been recorded from petrographic thin sections of chert belonging to the Sirbu Shale Formation,Bhander group,upper Vindhyans,Rajasthan.Recently, it was noticed that the assemblage also contains well preserved,large-sized acanthomorphic acritarchs, Trachyhystrichosphaera considered to be an age-marker microfossil of the Cryogenian (850 –630 Ma).It is reported for the first time from any Indian microfossil assemblage of Proterozoic succession.The other microfossils of the Sirbu Shale Formation are:well preserved simple,small and large-sized sphaeromorphs;complex acanthomorphs,cyanobacterial community;especially a very small-sized but exceptionally well preserved Obruchevella ,a form resembling Volvox colonies; cf.vase-shaped microfossils and morphologies,possibly inclining towards fungal affinity,or lichen- like symbiotic associations of algae and fungi.Till date, Trachyhystrichosphaera has so far not been reported from successions older than the Tonian (1000 –850 Ma).It is believed that acanthomorphs attained maximum size in Ediacaran (630 –542 Ma),and further decreased in size in the Cambrian.The global paleontological literature indicates that Trachyhystrichosphaera ranges in age from Tonian –Ediacaran (1000 –542 Ma). The present record of Trachyhystrichosphaera as well as the earlier studies of micro and megascopic life of the Bhander Group in general and the Sirbu Shale in particular (aided by the absence of any Cambrian fossil record)indicate that in all possibilities,age of the Sirbu Shale should lie near Cryogenian (850 –630 Ma)and the uppermost Bhander group,may incline towards the Ediacaran (630 –542 Ma).

    2011-03-01

    Full Text Available A new crocodyliform from the Upper Cretaceous (Campanian-Maastrichtian Presidente Prudente Formation of the Bauru Group is described based on two almost complete skulls and mandibles. The material comes from the "Tartaruguito" site, situated at an old railroad between the cities of Pirapozinho and Presidente Prudente, state of São Paulo, Brazil. The new species, Pepesuchus deiseae gen. et sp. nov., is classified in the clade Peirosauridae on the basis of three synapomorphies: the presence of five premaxillary teeth, the anterior two premaxillary alveoli nearly confluent, and the oval cross-section of the jugal along the lower temporal bar. The new taxon increases the outstanding crocodyliform diversity of the Bauru Group, particularly of the Peirosauridae, which might turn out to be one of the most representative clades of gondwanan mesoeucrocodylians.Um novo crocodilomorfo da Formação Presidente Prudente, Cretáceo Superior (Campaniano-Maastrichtiano do Grupo Bauru é descrito com base em dois exemplares, consistindo de crânio e mandíbulas quase completos. O material é procedente da localidade conhecida como "Tartaruguito", situada em um antigo ramal ferroviário que ligava as cidades de Pirapozinho e Presidente Prudente, Estado de São Paulo, Brasil. A nova espécie, denominada de Pepesuchus deiseae gen. et sp. nov., é classificada no clado Peirosauridae, com base em três sinapomorfias: presença de cinco dentes pré-maxilares, os dois primeiros alvéolos da pré-maxila quase confluentes e a secção transversal do jugal ao longo da barra temporal inferior oval. O novo táxon aumenta a marcante diversidade de crocodiliformes do Grupo Bauru e dos Peirosauridae, que poderá vir a ser um dos clados mais representativos de mesoeucrocodilianos gondwânicos.

    Upper gastrointestinal (UGI) bleed is one of the commonest medical emergencies. Cultural customs and practices may influence the development of disease conditions that may lead to UGI bleed. The purpose of this study was to compare the causes of UGI bleed in different ethnic groups among patients presenting to a large tertiary care hospital with acute UGI bleed. A retrospective study was conducted examining data available in the endoscopy register at the B. P. Koirala Institute of Health Sciences (BPKIHS) in Nepal for patients presenting with UGI bleed over one calendar year. Study subjects were categorized into one of a few broad categories of ethnic groups: Khas, Newar, SeTaMaGuRaLi, Maithali and others. Demographic information and endoscopic diagnoses were abstracted. The relative frequencies of different causes of UGI bleed were compared across the ethnic groups using the chi2 test. One hundred and eighty-nine patients underwent endoscopy for UGI bleed in the time period studied. The mean age of the study cohort was 49.6 years and consisted of 71.0% males and 29.0% females. Overall the commonest cause of upper GI bleed was gastric ulcer. Esophageal varices was the commonest cause in the SeTaMaGuRaLi group, accounting for 33.3%. The relative frequency of esophageal varices as the cause of upper GI bleed was statistically significantly different among the various ethnic groups, with the SeTaMaGuRaLi group having the highest relative frequency (p-value 0.02). Physicians taking care of patients with upper GI bleed in Nepal should be aware of the high relative frequency of esophageal varices as a cause of upper GI bleed, and especially so among certain ethnic groups.

    The cascaded reservoir group in upper Yellow River has the integrated function of ice jam flood prevention and power generation. The main factors which affect the utilization of the ice jam flood prevention volume of Liujiaxia reservoir are analyzed during the period of ice jam flood prevention, based on the input of new power station in upper Yellow River, the method of cascaded compensating scheduling are applied and the relation curve between the ice jam flood prevention volume and the cascaded output power of Liujiaxia reservoir is calculated, and the scheduling multi-objective solution set for the reservoir is obtained. On this basis, the new scheduling mode solving the reservoir integrated scheduling problem in upper Yellow River during the period of ice jam flood prevention is discussed. Comparing with the regular scheduling results, the new scheduling mode based on multi-objective solution set has the outstanding advantage in solving the problem of multi-objective scheduling of cascaded reservoir group.

    Aquifer thermal energy storage (ATES) is predicted to be the most cost-effective technology for seasonal storage of low-grade thermal energy. Approximately 60% of the US is underlain with aquifers potentially suitable for underground energy storage. Under sponsorship of the US Department of Energy (DOE), Pacific Northwest Laboratory (PNL), which is operated by Battelle Memorial Institute, has managed numerical modeling, laboratory studies, evaluation of environmental and institutional issues, and field testing of ATES at several sites. This report describes the monitoring and evaluation (under the auspices of PNL) of an ATES chill system constructed and operated by the University of Alabama at Tuscaloosa, Alabama. The system is the first such system to be monitored in a comprehensive manner. Results support both the promise and problems likely to be encountered in such systems. Chill ATES has the potential to substantially reduce energy consumption and, especially, summer peak cooling electrical demand. However, the geohydrologic environment that the system will use must be a major element in system design and operation. 9 refs., 25 figs., 10 tabs.

    New data from detailed measured sections permit comprehensive analysis of the sequence framework of the Furongian (Upper Cambrian; Jiangshanian and Sunwaptan stages) Tunnel City Group (Lone Rock Formation and Mazomanie Formation) of Wisconsin and Minnesota. The sequence-stratigraphic architecture of the lower part of the Sunwaptan Stage at the base of the Tunnel City Group, at the contact between the Wonewoc Formation and Lone Rock Formation, records the first part of complex polyphase flooding (Sauk III) of the Laurentian craton, at a scale smaller than most events recorded by global sea-level curves. Flat-pebble conglomerate and glauconite document transgressive ravinement and development of a condensed section when creation of accommodation exceeded its consumption by sedimentation. Thinly-bedded, fossiliferous sandstone represents the most distal setting during earliest highstand. Subsequent deposition of sandstone characterized by hummocky or trough cross-stratification records progradational pulses of shallower, storm- and wave-dominated environments across the craton before final flooding of Sauk III commenced with carbonate deposition during the middle part of the Sunwaptan Stage. Comparison of early Sunwaptan flooding of the inner Laurentian craton to published interpretations from other parts of North America suggests that Sauk III was not a single, long-term accommodation event as previously proposed.

    Full Text Available The purpose of this study was to compare lower and upper extremity strength of individuals with Down syndrome in terms of age and gender. Nineteen females (52.8% and 17 males (47.2% individuals with Down syndrome (Trisomy 21 type who continue special education and rehabilitation centers participated in the study. The average age of participants was 21.25±6.25 years, average height: 152.18±8.01cm, body weight average: 65.60±18.28kg. There was no statistically significant difference between lower and upper extremity results of Down's syndrome patients (p <0.05. In terms of gender, (Female: 15.8±5.6, male: 11.9 ± 4.8, p=0.03 it were found to be statistically better than boys in terms of horizontal jump (female: 71.7±20.5, male: 55.12±19.7, p=0.02 and vertical jump. As a result, lower and upper extremity strength in different age groups of individuals was found to be similar. However, it can be said that girls with Down syndrome have better explosive strength than men.

    New data from detailed measured sections permit a comprehensive revision of the sedimentary facies of the Furongian (upper Cambrian; Jiangshanian and Sunwaptan stages) Tunnel City Group (Lone Rock Formation and Mazomanie Formation) of Wisconsin and Minnesota. Heterogeneous sandstones, comprising seven lithofacies along a depositional transect from shoreface to transitional-offshore environments, record sedimentation in a storm-dominated, shallow-marine epicontinental sea. The origin of glauconite in the Birkmose Member and Reno Member of the Lone Rock Formation was unclear, but its formation and preserved distribution are linked to inferred depositional energy rather than just net sedimentation rate. Flat-pebble conglomerate, abundant in lower Paleozoic strata, was associated with the formation of a condensed section during cratonic flooding. Hummocky cross-stratification was a valuable tool used to infer depositional settings and relative paleobathymetry, and the model describing formation of this bedform is expanded to address flow types dominant during its genesis, in particular the importance of an early unidirectional component of combined flow. The depositional model developed here for the Lone Rock Formation and Mazomanie Formation is broadly applicable to other strata common to the early Paleozoic that document sedimentation along flooded cratonic interiors or shallow shelves.

    Based on the long period digital surface wave data recorded by 11 CDSN stations and 11 IRIS stations, the dispersion curves of the group velocities of fundamental mode Rayleigh waves along 647 paths, with the periods from 10 s to 92 s, were measured by multi-filter. Their distribution at 25 central periods within the region of 18((54(N, 70(~140(E was inverted by Dimtar-Yanovskaya method. Within the period from 10 s to 15.9 s, the group velocity distribution is laterally inhomogeneous and is closely related to geotectonic units, with two low velocity zones located in the Tarim basin and the East China Sea and its north regions, respectively. From 21 s to 33 s, the framework of tectonic blocks is revealed. From 36.6 s to 40 s, the lithospheric subdivision of the Chinese mainland is obviously uncovered, with distinct boundaries among the South-North seismic belt, the Tibetan plateau, the North China, the South China and the Northeast China. Four cross-sections of group velocity distribution with period along 30(N, 38(N, 90(E and 120(E, are discussed, respectively, which display the basic features of the crust and upper mantle of the Chinese mainland and its neighboring regions. There are distinguished velocity differences among the different tectonic blocks. There are low-velocity-zones (LVZ) in the middle crust of the eastern Tibetan plateau, high velocity featured as stable platform in the Tarim basin and the Yangtze platform, shallow and thick low-velocity-zone in the upper mantle of the North China. The upper mantle LVZ in the East China Sea and the Japan Sea is related to the frictional heat from the subduction of the Philippine slab and the strong extension since the Himalayan orogenic period.

    Thermal maturity of the Upper Triassic to Lower Jurassic Nampo Group, a sediment-fill of the Chungnam Basin located in the central western part of South Korea, was assessed by illite crystallinity measurement and sandstone microtexture analysis. The Nampo Group consists of a fluvio-lacustrine deposit bearing meta-anthracitic coals and was over-thrusted by the basement rocks. Sandstones are characterized by down sequence increasing illite crystallinity, from anchizone to epizone, which is strongly suggestive of burial heating. Deep-burial diagenesis and deformation are evidenced by well-developed pressure solution textures, whose intensity tends to increase down sequence, and by ductile deformation in the lowermost strata. On the basis of the result of illite crystallinity measurement, the maximum paleo-temperature and total burial depth of the Nampo Group are estimated to be ca 340{sup o}C and 10 km, respectively; these conditions are in good agreement with the observed ductile deformation features. The absence of strata younger than the Nampo Group in and around the Chungnam Basin suggests that deep burial of the Nampo Group was caused by tectonic crustal loading. The tectonic overload was because of basement over-thrusting that occurred during the Jurassic Daebo orogeny, which is closely related to the orthogonal subduction of the Izanagi Plate beneath the East Asian continent. Subsequent hydrothermal alteration disturbed the thermal maturity pattern, resulting in anomalously high illite crystallinity and meta-anthracitization.

    The Upper Cretaceous El Chanate Group, northwest Sonora, Mexico, is a 2.8km thick clastic sedimentary sequence deposited in a continental basin closely related to volcanic activity. It consists of three formations: the Pozo Duro (oldest), the Anita, and the Escalante (youngest). Petrographic study, conglomerate pebble counts, and U-Pb geochronology of detrital zircons were performed to determine the source and age of this sequence, and to interpret its tectonic setting. In the sandstones of all three formations, the most abundant grains are those of volcanic composition (Q38F22L 40, Q35F19L46, and Q 31F22L47, respectively). The Pozo Duro Formation includes well-rounded quartz-arenite clast conglomerates, whereas conglomerates of the two upper units have clasts predominantly of andesitic and rhyolitic composition. The most likely source for these sediments was the Jurassic volcanic arc exposed in northern Sonora and southern Arizona. Zircons from five sandstone samples define two main age groups, Proterozoic and Mesozoic. The first ranges mostly from 1000 to 1800Ma, which suggests the influence of a cratonic source. This zircon suite is interpreted to be recycled and derived from the same source area as the quartz-rich sandstone clasts in the basal part of the section. Mesozoic zircons range from Triassic to Late Cretaceous, which confirms the proposed Late Cretaceous age for the sequence, and also corroborates Jurassic felsic source rocks. Another possible source was the Alisitos volcanic arc, exposed along the western margin of the Baja California Peninsula. Of regional significance is the great similarity between the El Chanate Group and the McCoy Mountains Formation of southeastern California and southwestern Arizona. Both are Cretaceous, were deposited in continental environments, and have similar zircon-age patterns. Also, both exhibit intense deformation and locally display penetrative foliation. These features strongly suggest that both units underwent

Microfacies are foraminiferal-algal wackestones; stratigraphy is Upper Turonian (?Lower Coniacian. It is shown that the original description was based on oblique sections leading to the incorrect assumption of a piriform segment morphology. Instead, P. gosaviensis is a representative of Permocalculus of the group with constrictions/swellings along the segments (waxing-and-waning type. Permocalculus nikolapantici Radoičić from the Upper Turonian of Serbia is considered a junior synonym of Permocalculus gosaviensis Schlagintweit.

    2013-04-01

    The formations of the Saxonian Cretaceous have been combined in the so-called Elbtal Group. Their sedimentation took place in a terrestrial to neritic environment palaeogeographically located between the Mid-European Island (MEI) in the SW and the Lusatian Massif in the NE. The through extended from the narrow marine strait of Saxony into the broad Bohemian Cretaceous Basin (Czech Republic) further to the SE. Deposition has been dominated by marine siliciclastics that accumulated on a graded shelf with basically three main facies zones: the coarse-grained nearshore zone ("Küstensandsteinzone"), the transitional zone ("Faziesübergangszone") and the fine-grained marly offshore facies zone ("Plänerfazies"). In general, transgression proceeded in late Early Cenomanian times from the N. Relictic remains of these marine bioclastic conglomerates (Meißen Formation) only occur in the northwesternmost area of the basin around Meißen and are related to the highstand of the depositional sequence Cenomanian 3 (DS Ce 3). After a short stratigraphic gap, onlap continued in the Middle Cenomanian with the following Niederschöna Formation consisting of coarse-grained braided river deposits at the base grading via carbonaceous point-bar cycles of a meandering river system into bioturbated, partly cross-bedded estuarine sediments toward the top. These sediments record DS Ce 4 and are capped by a paleosol. Sedimentation of DS Ce 5 started with a renewed transgressional pulse initiating the Late Cenomanian. The strata consist of bioturbated, cross-bedded predominantly fine- to medium-grained quartz sandstones with some shell-rich horizons corresponding to the Oberhäslich Formation. The unconformably overlying DS Tu 1 comprises the uppermost Cenomanian Dölzschen Formation and the Lower Turonian part of the Schmilka Formation. The onset of this depositional sequence is marked by a major transgression ("plenus Transgression) drowning the remaining pre-transgression topography

    Full Text Available The Nanhua basin in South China hosts well-preserved middle–late Neoproterozoic sedimentary and volcanic rocks that are critical for studying the basin evolution, the breakup of the supercontinent Rodinia, the nature and dynamics of the “snowball” Earth and diversification of metazoans. Establishing a stratigraphic framework is crucial for better understanding the interactions between tectonic, paleoclimatic and biotic events recorded in the Nanhua basin, but existing stratigraphic correlations remain debated, particularly for pre-Ediacaran strata. Here we report new Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS U-Pb zircon ages from the middle and topmost Wuqiangxi Formation (the upper stratigraphic unit of the Banxi Group in Siduping, Hunan Province, South China. Two samples show similar age distribution, with two major peaks at ca. 820 Ma and 780 Ma and one minor peak at ca. 910 Ma, suggesting that the Wuqiangxi sandstone was mainly sourced from Neoproterozoic rocks. Two major age peaks correspond to two phases of magmatic events associated with the rifting of the Nanhua basin, and the minor peak at ca. 910 Ma may correspond to the Shuangxiwu volcanic arc magmatism, which represents pre-collision/amalgamation subduction on the southeastern margin of the Yangtze Block. The youngest zircon group from the topmost Wuqiangxi Formation has a weighted mean age of 714.6 ± 5.2 Ma, which is likely close to the depositional age of the uppermost Banxi Group. This age, along with the ages reported from other sections, constrains that the Banxi Group was deposited between ca. 820 Ma and ca. 715 Ma. The age of 714.6 ± 5.2 Ma from the top of the Wuqiangxi Formation is indistinguishable with the SIMS U-Pb age of 715.9 ± 2.8 Ma from the upper Gongdong Formation in the Sibao village section of northern Guangxi, South China. It is also, within uncertainties, overlapped with two TIMS U-Pb ages from pre

    The Upper Triassic (Adamanian LVF) Ojo Huelos Member of the San Pedro Arroyo Formation (Chinle Group) is a distinctive, carbonate-rich unit that occurs in the lower Chinle section of central New Mexico. The member consists mainly of micritic lime mudstones, ostracodal wackestones to grainstones, peloidal grainstones and distinctive pisolitic rudstones, interbedded with fine-grained siliciclastic mudstones. Most limestones exhibit some evidence of pedogenic brecciation and root penetration, and porous fabrics similar to those of modern limestone tufas occur locally. The interbedded mudstones are typically lenticular and commonly display a blocky ped fabric in which subequant peds are separated by sparry calcite veins. Fossils from the Ojo Huelos Member are freshwater (darwinulid) ostracodes, various freshwater fishes and aquatic/amphibious tetrapods-metoposaurs and phytosaurs. We interpret the carbonate facies as the deposits of carbonate lakes, ponds and wetlands that were partly spring-fed, whereas the interbedded and surrounding mudstones were alluvial in origin. The groundwater and overland hydrology of the region was likely controlled by the relative proximity to an upland recharge area in the Mogollon Highlands to the south, but sedimentary fabrics record strong overprinting by desiccation and pedogenic reworking. Consequently, we interpret the Ojo Huelos Member as recording a climate that varied from subhumid to semi-arid, which caused episodic falls in the hydrologic base-level. This resulted in landscape degradation, exemplified by significant pedogenic and erosional reworking of the carbonate sediments and fluvial incision.

    Marine group I Crenarchaeota (MGI) represents a ubiquitous and numerically predominant microbial population in marine environments. An understanding of the spatial dynamics of MGI and its controlling mechanisms is essential for an understanding of the role of MGI in energy and element cycling in the ocean. In the present study, we investigated the diversity and abundance of MGI in the East China Sea (ECS) by analysis of crenarchaeal 16S rRNA gene, the ammonia monooxygenase gene amoA, and the biotin carboxylase gene accA. Quantitative PCR analyses revealed that these genes were higher in abundance in the mesopelagic than in the euphotic zone. In addition, the crenarchaeal amoA gene was positively correlated with the copy number of the MGI 16S rRNA gene, suggesting that most of the MGI in the ECS are nitrifiers. Furthermore, the ratios of crenarchaeal accA to amoA or to MGI 16S rRNA genes increased from the euphotic to the mesopelagic zone, suggesting that the role of MGI in carbon cycling may change from the epipelagic to the mesopelagic zones. Denaturing gradient gel electrophoretic profiling of the 16S rRNA genes revealed depth partitioning in MGI community structures. Clone libraries of the crenarchaeal amoA and accA genes showed both "shallow" and "deep" groups, and their relative abundances varied in the water column. Ecotype simulation analysis revealed that MGI in the upper ocean could diverge into special ecotypes associated with depth to adapt to the light gradient across the water column. Overall, our results showed niche partitioning of the MGI population and suggested a shift in their ecological functions between the euphotic and mesopelagic zones of the ECS.

    The Upper Cretaceous Navarro and Taylor Groups in the western part of the Western Gulf Province were assessed for undiscovered oil and gas resources in 2003. The area is part of the Smackover-Austin-Eagle Ford Composite Total Petroleum System. The rocks consist of, from youngest to oldest, the Escondido and Olmos Formations of the Navarro Group and the San Miguel Formation and the Anacacho Limestone of the Taylor Group (as well as the undivided Navarro Group and Taylor Group). Some units of the underlying Austin Group, including the 'Dale Limestone' (a term of local usage that describes a subsurface unit), were also part of the assessment in some areas. Within the total petroleum system, the primary source rocks comprise laminated carbonate mudstones and marine shales of the Upper Jurassic Smackover Formation, mixed carbonate and bioclastic deposits of the Upper Cretaceous Eagle Ford Group, and shelf carbonates of the Upper Cretaceous Austin Group. Possible secondary source rocks comprise the Upper Jurassic Bossier Shale and overlying shales within the Upper Jurassic to Lower Cretaceous Cotton Valley Group, Lower Cretaceous marine rocks, and the Upper Cretaceous Taylor Group. Oil and gas were generated in the total petroleum system at different times because of variations in depth of burial, geothermal gradient, lithology, and organic-matter composition. A burial-history reconstruction, based on data from one well in the eastern part of the study area (Jasper County, Tex.), indicated that (1) the Smackover generated oil from about 117 to 103 million years ago (Ma) and generated gas from about 52 to 41 Ma and (2) the Austin and Eagle Ford Groups generated oil from about 42 to 28 Ma and generated gas from about 14 Ma to the present. From the source rocks, oil and gas migrated upsection and updip along a pervasive system of faults and fractures as well as along bedding planes and within sandstone units. Types of traps include stratigraphic pinchouts, folds, faulted

    The volcanic groups of Bad Bertrich and Wartgesberg are situated in the most southeastern part of the Quaternary West Eifel Volcanic Field (WEVF) and are, therefore, of major interest for understanding origin and timing of the WEVF. For geomorphological reasons the eruptions were placed within the last Glacial. Recent Ar/Ar-dating results suggest ages of 32±11 ka and 31±11 ka, respectively (MERTZ ET AL. 2015). We used xenoliths from Lower Devonian country rock (slates and quarzitic slates) and a maar tephra to explore the feasibility of thermoluminescence (TL) to date the eruptions more accurately. Fine-grained (4-30 μm) quartz was extracted from the samples by grinding and etching in H2SiF6. Because of their high saturation dose the red (620 nm) TL-emissions from quartz was measured using a SAR protocol. Dose-rates were computed based on analytical results from thick source alpha counting (U, Th), ICP-OES (K) and high resolution gamma spectrometry. For the Wartgesberg volcanic group our preliminary results agree with the independent Ar/Ar-ages but can bracket the eruption age to 33±3 ka. Furthermore, the suggestion by RICHTER ET AL. (2015) to avoid quartz extracted from crustal xenoliths having been heated too high is confirmed. For the Bad Bertrich volcanic group our preliminary results are ambiguous. The "Hardtmaar"-Tephra is dated to 27±3 ka in agreement with the age of this group supposed by MERZ ET AL. (2015). Three xenoliths from the nearby "Facher Höhe" scoria cone, however, yielded consistent but significantly lower TL ages. From the view of volcanic stratigraphy there is so far no evidence of a significantly younger eruption phase. From one of these samples we so far found evidence of non-thermal fading as described by RICHTER ET AL. (2015) which needs further investigation. Stimulated by results of PREUSSER ET AL. (2011) we aim at applying also OSL and IRSL dating of the xenoliths and the maar tephra to clarify the age of the "Facher Höhe" scoria

  9. Upper limits on carbon group ions near the orbit of Titan: Implications for methane escape from Titan

    Science.gov (United States)

    Crary, Frank; Smith, H. Todd; Reisenfeld, Daniel; Young, Dave

    High neutral methane escape rates from Titan (˜3x109 cm-2 s-1 ) have been inferred from Cassini Ion and Neutral Mass Spectrometer observations [Yelle et al., 2008]. This is much higher than past predictions (e.g. due to Jeans loss). To investigate this hypothesis, we have examined Cassini Cassini Plasma Spectrometer (CAPS) data obtained near Titan's orbit. We have used the CAPS linear electric field (LEF) mass spectra, which provide high resolution measurements of atomic ions and the atomic constituents of molecular ions. The expected lifetime of neutral methane is sufficiently long that escaping molecules would not ionize in Titan's immediate vicinity. However, ionospheric methane ions are observed in Titan's atmosphere. To distinguish between these two possible sources of methane ions, we have examined spectra obtained within five Saturn radii of Titan's orbit, but at distances of over one Saturn radius from Titan itself. Between March 2005 and Dec. 2009, 5466 LEF spectra were obtained in this region. These data show a clear oxygen peak, either from atomic O+ or from fragmentation of oxygen-bearing molecular ions. A weaker nitrogen peak, with 5.9% the amplitude of the oxygen peak, is also present. At the instrument's noise level, no carbon peak is present. This non-detection corresponds to an abundance of carbon ions and carbon-bearing molecular ions under 0.28% that of oxygen and oxygen-bearing ions. Estimates of the neutral and ion loss rates, and ion production rates, allow us to convert this upper limit into an upper limit on the escape rate of neutral methane from Titan. Unless there is some currently unknown and efficient loss process for neutral methane (i.e. other than ionization), this upper limit is several orders of magnitude lower than the escape rate determined by Yelle et al., 2008.

    The taxonomy of the calcareous nannofossil Arkhangelskiella is revised using the results of a biometric analysis performed on 599 specimens from various stratigraphic levels throughout the upper Campanian-Maastrichtian of the Stevns-1 borehole, Denmark. Combined qualitative labelling and biometric...... in the coccolith length and in the rim width, and that the central opening is an important additional parameter allowing distinction between the different morphogroups. Biometric analysis shows, however, that the morphogroups are strongly overlapping on all measured parameters. Therefore, the three distinct...

    Geochemical monitoring of Lower Tuscaloosa Formation (LTF) brine continues at the Cranfield CO2-enhanced oil recovery (EOR) and sequestration site to investigate the potential for the geologic storage of large volumes of CO2 in saline aquifers and depleted reservoirs. Cranfield oil field is a domal depleted oil and gas reservoir in the Mississippi Interior Salt Basin, with production in heterogeneous fluvial sandstones of the LTF (depth ~3000 m). CO2 flood began in July 2008. Brine samples were collected from selected production wells in March and December 2009, April 2010, and November 2011. Intensive sampling also was conducted for the first 18 days of a CO2 injection experiment below the oil-water contact (December 2009) at the Detailed Area of Study (DAS) 3-well array. The sampling objectives are to define the geochemical composition of the pre-injection brine, and to understand the geochemical changes resulting from interactions between the injected CO2, brine, and reservoir minerals. Results show that Tuscaloosa brine is Na-Ca-Cl type with total salinity ranging from ~140 to 160 g/L TDS (50 samples). Relatively large variations are observed in major divalent cations (Ca ~7,500-14,000 mg/L, Mg ~800-1,250 mg/L, Sr ~475-750 mg/L). Significant positive correlations are noted amongst Ca, Mg, Sr, Ba, and Br, whereas these solutes all trend negatively with Na and Cl. These results may be interpreted as possible binary mixing between two end-member waters: (1) high Na-Cl (51 and 97 g/L, respectively), low Ca, Mg, Sr, and Br (~7500, 800, 475, 280 mg/L, respectively); and (2) low Na-Cl (40 and 86 g/L), high Ca, Mg, Sr, and Br (~14,000, 1250, 750, 480 mg/L). This apparent binary mixing has no obvious correlation to CO2 injection, which suggests that observed variations are due to natural heterogeneities in LTF brine within the Cranfield dome. The variations may indicate vertical and/or lateral proximity to a halite source (i.e. salt dome), with the high Na-Cl, low Br

  12. Making sense of 'lower' and 'upper' stem-group Euarthropoda, with comments on the strict use of the name Arthropoda von Siebold, 1848.

    The ever-increasing number of studies that address the origin and evolution of Euarthropoda - whose extant representatives include chelicerates, myriapods, crustaceans and hexapods - are gradually reaching a consensus with regard to the overall phylogenetic relationships of some of the earliest representatives of this phylum. The stem-lineage of Euarthropoda includes numerous forms that reflect the major morphological transition from a lobopodian-type to a completely arthrodized body organization. Several methods of classification that aim to reflect such a complex evolutionary history have been proposed as a consequence of this taxonomic diversity. Unfortunately, this has also led to a saturation of nomenclatural schemes, often in conflict with each other, some of which are incompatible with cladistic-based methodologies. Here, I review the convoluted terminology associated with the classification of stem-group Euarthropoda, and propose a synapomorphy-based distinction that allows 'lower stem-Euarthropoda' (e.g. lobopodians, radiodontans) to be separated from 'upper stem-Euarthropoda' (e.g. fuxianhuiids, Cambrian bivalved forms) in terms of the structural organization of the head region and other aspects of overall body architecture. The step-wise acquisition of morphological features associated with the origins of the crown-group indicate that the node defining upper stem-Euarthropoda is phylogenetically stable, and supported by numerous synapomorphic characters; these include the presence of a deutocerebral first appendage pair, multisegmented head region with one or more pairs of post-ocular differentiated limbs, complete body arthrodization, posterior-facing mouth associated with the hypostome/labrum complex, and post-oral biramous arthropodized appendages. The name 'Deuteropoda' nov. is proposed for the scion (monophyletic group including the crown-group and an extension of the stem-group) that comprises upper stem-Euarthropoda and Euarthropoda.

    The almost constant local regional development of the cancers of upper aero digestive organs requires the same special attention to cervical lymph node metastases, as well as to the primary neoplastic burning point. The surgical therapy alone or associated has a mutilating, damaging character, resulting in loss of an organ and function, most of the times with social implications, involving physical distortions with aesthetic consequences, which make the reintegration of the individual into society questionable. The problem of cervical lymph node metastases is vast and complex, reason why we approached several anatomical and physiological aspects of lymph vessels of the aero digestive organs. Among the available elements during treatment, the headquarters of the tumour, its histologic degree, and its infiltrative nature, each of them significantly influences the possibility of developing metastases.

    AIM: To investigate in a prospective study whether a simplified clinical score prior to endoscopy in upper gastrointestinal bleeding (UGIB) patients was able to predict endoscopic findings at urgent endoscopy.METHODS: All consecutive UGIB patients referred to a single endoscopic center during a 16 mo period were enrolled. Before endoscopy patients were stratified according to a simple clinical score (T-score),including T1 (high-risk), T2 (intermediate-risk) and T3 (low-risk). Endoscopy was performed in all cases within 2 h, and high-risk stigmata were considered for further analysis.RESULTS: Out of the 436 patients included into the study, 126 (29%) resulted to be T1, 135 (31%) T2,and 175 (40%) T3. Overall, stigmata of recent haernorrhage (SRH) were detected in 118 cases (27%). SRH occurred more frequently in Tt patients than in T2/T3 cases (85% vs 3.2%; x2 = 304.5309, P < 0.001). Older age (t = 3.311; P <0.01) and presence of comorbidities (x2 = 14.7458; P < 0.01) were more frequently detected in T1 than in T2/T3 patients.CONCLUSION: Our simplified clinical score appeared to be associated with the detection of endoscopic findings which may deserve urgent endoscopy. A further,randomised study is needed to assess its accuracy in safely scheduling endoscopy in UGIB patients.

    To improve science learning, science educators' teaching tools need to address two major criteria: teaching practice should mirror our current understanding of the learning process; and science teaching should reflect scientific practice. We designed a small-group learning (SGL) model for a fourth year university neurobiology course using these criteria and studied student achievement and attitude in five course sections encompassing the transition from individual work-based to SGL course design. All students completed daily quizzes/assignments involving analysis of scientific data and the development of scientific models. Students in individual work-based (Individualistic) sections usually worked independently on these assignments, whereas SGL students completed assignments in permanent groups of six. SGL students had significantly higher final exam grades than Individualistic students. The transition to the SGL model was marked by a notable increase in 10th percentile exam grade (Individualistic: 47.5%; Initial SGL: 60%; Refined SGL: 65%), suggesting SGL enhanced achievement among the least prepared students. We also studied student achievement on paired quizzes: quizzes were first completed individually and submitted, and then completed as a group and submitted. The group quiz grade was higher than the individual quiz grade of the highest achiever in each group over the term. All students--even term high achievers--could benefit from the SGL environment. Additionally, entrance and exit surveys demonstrated student attitudes toward SGL were more positive at the end of the Refined SGL course. We assert that SGL is uniquely-positioned to promote effective learning in the science classroom.

  18. Transition from confined to phreatic conditions as the factor controlling salinization and change in redox state, Upper subaquifer of the Judea Group, Israel

    An increase in salinity and change from oxic to anoxic conditions are observed in the Upper subaquifer of the Judea Group in the Kefar Uriyya pumping field at the western foothills of the Judea Mountains, Israel. Hydrogeological data indicate that the change, which occurs over a distance of only a few kilometers, coincides with a transition from confined to phreatic conditions in the aquifer. The deterioration in the water quality is explained as a result of seepage of more saline, organic-rich water from above, into the phreatic "roofed" part of the aquifer. The latter is derived from the bituminous chalky rocks of the Mount Scopus Group, which confine the aquifer in its southeastern part. In this confined part, water in perched horizons within the Mount Scopus Group cannot leak down and flow westward while leaching organic matter and accumulating salts. However, upon reaching the transition area from confined to phreatic conditions, seepage to the Judea Upper subaquifer is possible, thereby allowing it to be defined as a leaky aquifer. The incoming organic matter consumes the dissolved oxygen and allows bacterial sulfate reduction. The latter accounts for the H2S in the aquifer, as indicated by sulfur isotopic analyses of coexisting sulfate and sulfide. Thus, from an aquifer management point of view, in order to maintain the high quality of the water in the confined southeastern part of the Kefar Uriyya field, care should be taken not to draw the confined-roofed transition area further east by over pumping.

    We investigated the calcareous nannofossil biostratigraphy and paleoceanography of the Shimajiri Group in two exploratory wells (depths, 1243 and 1800 m) drilled on southern Okinawa-jima, Ryukyu Islands, southwestern Japan. Three late Miocene to Pliocene datum planes were identified: the first occurrence of Amaurolithus spp. (7.42 Ma), the last occurrence of Discoaster quinqueramus (5.59 Ma), and the first occurrence of Ceratolithus rugosus (5.12 Ma). These datum planes were also identified in two other deep wells on southern Okinawa-jima. Nutrient levels (reconstructed from the relative abundances of small Reticulofenestra spp., and the relative abundances of Discoaster spp. plus Sphenolithus abies) suggest that deposition of the Shimajiri Group (<8.29-3.50 Ma) occurred under conditions of increasing eutrophication. The eutrophication was likely caused by shallowing of the sedimentary basin, but a stepwise shift was associated with an abrupt eutrophication event that occurred in the northwestern Pacific Ocean at 5 Ma.

    Providing students with assignments that focus on critical thinking is an important part of their scientific and intellectual development. However, as class sizes increase, so does the grading burden, prohibiting many faculty from incorporating critical thinking assignments in the classroom. In an effort to continue to provide our students with meaningful critical thinking exercises, we implemented a novel group-centered, problem-based testing scheme. We wanted to assess how performing critical thinking problem sets as group work compares to performing the sets as individual work, in terms of student attitudes and learning outcomes. During two semesters of our recombinant DNA course, students had the same lecture material and similar assessments. In the Fall semester, student learning was assessed by two collaborative take-home exams, followed immediately by individual, closed-book in-class exams on the same content, as well as a final cumulative exam. Student teams on the take-home exams were instructor-assigned, and each team turned in one collaborative exam. In the Spring semester, the control group of students were required to turn in their own individual take-home exams, followed by the in-class exams and final cumulative exam. For the majority of students, learning outcomes were met, regardless of whether they worked in teams. In addition, collaborative learning was favorably received by students and grading was reduced for instructors. These data suggest that group-centered, problem-based learning is a useful model for achievement of student learning outcomes in courses where it would be infeasible to provide feedback on individual critical thinking assignments due to grading volume.

  1. Structure–Activity Relationship of Oligomeric Flavan-3-ols: Importance of the Upper-Unit B-ring Hydroxyl Groups in the Dimeric Structure for Strong Activities

    Full Text Available Proanthocyanidins, which are composed of oligomeric flavan-3-ol units, are contained in various foodstuffs (e.g., fruits, vegetables, and drinks and are strongly biologically active compounds. We investigated which element of the proanthocyanidin structure is primarily responsible for this functionality. In this study, we elucidate the importance of the upper-unit of 4–8 condensed dimeric flavan-3-ols for antimicrobial activity against Saccharomyces cerevisiae (S. cerevisiae and cervical epithelioid carcinoma cell line HeLa S3 proliferation inhibitory activity. To clarify the important constituent unit of proanthocyanidin, we synthesized four dimeric compounds, (−-epigallocatechin-[4,8]-(+-catechin, (−-epigallocatechin-[4,8]-(−-epigallocatechin, (−-epigallocatechin-[4,8]-(−-epigallocatechin-3-O-gallate, and (+-catechin-[4,8]-(−-epigallocatechin and performed structure–activity relationship (SAR studies. In addition to antimicrobial activity against S. cerevisiae and proliferation inhibitory activity on HeLa S3 cells, the correlation of 2,2-diphenyl-l-picrylhydrazyl radical scavenging activity with the number of phenolic hydroxyl groups was low. On the basis of the results of our SAR studies, we concluded that B-ring hydroxyl groups of the upper-unit of the dimer are crucially important for strong and effective activity.

    The 3500 lignite seam at the Gibbons Creek Mine in Grimes County, TX was sampled for pollen and spores at 10 cm intervals. The majority of samples are dominated (to 60%) by Momipites from the Juglandaceae (walnut family), as is typical of Jackson Group sediments. Other palynomorph taxa vary systematically, with a peak of pollen of the freshwater tree Nyssa (blackgum) and associated Rboipites angustus (to 17%) occurring at the base. Higher in the seam, increase (to 55%) of Cupuliferoipollenites (a chestnut-like grain) and Cyrillaceae-pollenites? ventosus (to 7%) percentages may indicate a higher salinity environment. A Chrysophyllum (satin leaf) peak (to 25%) near the top of the seam suggests relatively shallow fresh-water conditions. Core samples from an interval above the lignites represent a transgressive-regressive cycle in inner shelf clastics. These samples were taken at 40 cm or greater intervals and reveal the regional pollen flora. Although minor changes occur, palynomorph spectra are for the most part homogenous. The dominant grain is again Momipites coryloides, but in general percentages are lower (to 35%). Cupuliferoipollenites (to 17%), Chrysophyllum (to 5%), and Rhoipites angustus (to 3%) are not less important, but do not peak as they do in the lignite spectra. Palm leaf megafossils; in one sample suggest a clastic wetland; in this sample palm pollen (mostly Arecipites, representing the modern saw palmetto) reaches 73%. Another sample contains high (26%) percentages of the fern spore Lygodiumsporites adriennis. High percentages of these two taxa do not occur in the lignite samples.

    Full Text Available BackgroundRobotic rehabilitation of the upper limb following neurological injury has been supported through several large clinical studies for individuals with chronic stroke. The application of robotic rehabilitation to the treatment of other neurological injuries is less developed, despite indications that strategies successful for restoration of motor capability following stroke may benefit individuals with incomplete spinal cord injury (SCI as well. Although recent studies suggest that robot-aided rehabilitation might be beneficial after incomplete SCI, it is still unclear what type of robot-aided intervention contributes to motor recovery.MethodsWe developed a novel assist-as-needed (AAN robotic controller to adjust challenge and robotic assistance continuously during rehabilitation therapy delivered via an upper extremity exoskeleton, the MAHI Exo-II, to train independent elbow and wrist joint movements. We further enrolled seventeen patients with incomplete spinal cord injury (AIS C and D levels in a parallel-group balanced controlled trial to test the efficacy of the AAN controller, compared to a subject-triggered (ST controller that does not adjust assistance or challenge levels continuously during therapy. The conducted study is a stage two, development-of-concept pilot study.ResultsWe validated the AAN controller in its capability of modulating assistance and challenge during therapy via analysis of longitudinal robotic metrics. For the selected primary outcome measure, the pre–post difference in ARAT score, no statistically significant change was measured in either group of subjects. Ancillary analysis of secondary outcome measures obtained via robotic testing indicates gradual improvement in movement quality during the therapy program in both groups, with the AAN controller affording greater increases in movement quality over the ST controller.ConclusionThe present study demonstrates feasibility of subject-adaptive robotic therapy

    The US Geological Survey recognizes six major plays for nonassociated gas in Tertiary and Upper Cretaceous low-permeability strata of the Uinta Basin, Utah. For purposes of this study, plays without gas/water contacts are separated from those with such contacts. Continuous-saturation accumulations are essentially single fields, so large in areal extent and so heterogeneous that their development cannot be properly modeled as field growth. Fields developed in gas-saturated plays are not restricted to structural or stratigraphic traps and they are developed in any structural position where permeability conduits occur such as that provided by natural open fractures. Other fields in the basin have gas/water contacts and the rocks are water-bearing away from structural culmination`s. The plays can be assigned to two groups. Group 1 plays are those in which gas/water contacts are rare to absent and the strata are gas saturated. Group 2 plays contain reservoirs in which both gas-saturated strata and rocks with gas/water contacts seem to coexist. Most units in the basin that have received a Federal Energy Regulatory Commission (FERC) designation as tight are in the main producing areas and are within Group 1 plays. Some rocks in Group 2 plays may not meet FERC requirements as tight reservoirs. However, we suggest that in the Uinta Basin that the extent of low-permeability rocks, and therefore resources, extends well beyond the limits of current FERC designated boundaries for tight reservoirs. Potential additions to gas reserves from gas-saturated tight reservoirs in the Tertiary Wasatch Formation and Cretaceous Mesaverde Group in the Uinta Basin, Utah is 10 TCF. If the potential additions to reserves in strata in which both gas-saturated and free water-bearing rocks exist are added to those of Group 1 plays, the volume is 13 TCF.

    A new Podocnemidinura specimen from the Upper Cretaceous Bauru Group (Paraná Basin) of southeastern Brazil was described. The Bauru Group provided an important portrait of the Brazilian Mesozoic terrestrial biota, which boasts a vertebrate fauna formed from fishes, frogs, lacertilians, crocodyliforms, dinosaurs and mammals; records of palynomorphs; and invertebrate fauna consisted of gastropods, bivalves, ostracods and conchostracans. Nevertheless, the age of these continental deposits is not precisely estimated, which prevents global correlations, and its fauna is argued to be endemic. The new specimen described is the first turtle from the Santo Anastácio Formation, and its morphological comparison with other South American forms provided a significant advancement in the understanding of the age of this unit (Late Cretaceous). This study permitted a revision of the turtle taxa of the Bauru Group. As a result, some taxa were considered synonym, including the new Santo Anastácio form. The specimen is still unnamed due to the absence of skull characters that preclude its accurate positioning within the Bauru Group skull-based taxa. In addition, the phylogenetic affinities of this taxon were analyzed into Podocnemidinura clade.

    The U.S. Geological Survey (USGS) recently completed an assessment of the undiscovered oil and gas potential of the Upper Cretaceous Navarro and Taylor Groups in the Western Gulf Province of the Gulf Coast region (fig. 1) as part of a national oil and gas assessment effort (USGS Navarro and Taylor Groups Assessment Team, 2004). The assessment of the petroleum potential of the Navarro and Taylor Groups was based on the general geologic elements used to define a total petroleum system (TPS), including hydrocarbon source rocks (source rock maturation, hydrocarbon generation and migration), reservoir rocks (sequence stratigraphy and petrophysical properties), and hydrocarbon traps (trap formation and timing). Using this geologic framework, the USGS defined five assessment units (AU) in the Navarro and Taylor Groups as parts of a single TPS, the Smackover-Austin-Eagle Ford Composite TPS: Travis Volcanic Mounds Oil AU, Uvalde Volcanic Mounds Gas and Oil AU, Navarro-Taylor Updip Oil and Gas AU, Navarro-Taylor Downdip Gas and Oil AU, and Navarro-Taylor Slope-Basin Gas AU (table 1).

  9. High frequency peritidal cycles of the upper Araras Group: Implications for disappearance of the neoproterozoic carbonate platform in southern Amazon Craton

    The Araras Group is an extensive carbonate platform developed at the southeastern margin of the Amazon Craton during the Neoproterozoic. The Nobres Formation corresponds to the upper unit of the Neoproterozoic Araras Group. It is exposed in road cuts and quarries in the Northern Paraguay Belt, and is characterized by meter-scale shallowing upward cycles. Forty-four fourth-to fifth-order parasequence cycles are enclosed into three third order sequences/megacycles, unconformably overlain by siliciclastic deposits of the Alto Paraguay Group. The cycles are generally of peritidal type, limited by exposure surfaces composed of asymmetrical tidal flat/sabkha lithofacies in the basal Nobres Formation. They consist of fine dolostone, intraclastic dolostones with megaripples, stromatolites biostrome, sandy dolostone with enterolithic structures and silicified evaporite molds. Upsection, the cycles progressively become symmetrical, comprising arid tidal flat deposits with abundant stromatolite biostrome, fine-grained sandstone and rare evaporitic molds. The stacking patterns for hundreds of meters indicate continuous and recurrent generation of accommodation space, probably triggered by subsidence concomitant with relative sea-level changes. Palynomorphs found in the upper part of Nobres Formation comprehend spheroidal forms, such as Leiospharidia, rare filamentous and acanthomorphous acritarchs, mostly Tanarium correlated to the Ediacaran Complex Acantomorph Palynoflora of ˜580-570 Ma. Previous data of carbon isotopes and paleogeographic reconstructions, and also the presence of evaporites and storm-influenced deposits in the Araras Group, suggest a wet to tropical setting for Amazonia during the Mid-Ediacaran, which is incompatible with previous claims for Gaskiers-related glacial sedimentation in the region. During the final stages of evolution of the Araras carbonate platform, a progressive input of terrigenous has occurred in the peritidal setting likely due tectonic

    Twenty-eight selected sites (individual beds) in the Moenave Formation at the Echo Cliffs, northern Arizona, strata give a Hettangian paleomagnetic pole at 63.7°N, 59.7°E (dp = 2.6°, dm = 5.1°). The Wingate Sandstone and Rock Point Formation at Comb Ridge, southeast Utah, provide a Rhaetian paleopole at 57.4°N, 56.6°E (N = 16 sites; dp = 3.4, dm = 6.5). High unblocking temperatures (>600°C), high coercivity, and data analyses indicate that the characteristic magnetization is primarily a chemical remanence residing in hematite. The Hettangian and Rhaetian poles are statistically indistinguishable (at 95% confidence), they resemble existing data for the Glen Canyon Group, and they provide further validation to the J1 cusp of the North American apparent pole wander path (APWP). The red siltstone and upper members of the Chinle Group, on the south flank of the Uinta Mountains, northern Utah, define a Rhaetian pole at 51.6°N, 70.9°E (N = 20 sites; dp = 3.5°, dm = 6.9°). The Gartra and upper members of the Chinle Group in the north flank of the Uinta Mountains, give paleopoles at 52.0°N, 100.3°E (N = 6 sites; dp = 5.4°, dm = 10.5°) and 50.9°N, 50.1°E (N = 5 sites; dp = 8.8°, dm = 17.5°), respectively. These data indicate no significant rotation of the Uinta Mountains with respect to the craton. In total, data for the plateau and its bordering region of Cenozoic uplifts support estimates of small rotation of the plateau and provide evidence against the hypothesis of a Late Triassic standstill of the North American APWP. Our magnetostratigraphic results are consistent with lithographic and biostratigraphic data that place the Triassic-Jurassic boundary within the Dinosaur Canyon Member of the Moenave Formation, not at a regional hiatus.

  12. Production history matching to determine reservoir properties of important coal groups in the Upper Pottsville formation, Brookwood and Oak Grove fields, Black Warrior Basin, Alabama.

    2013-01-01

    The Black Warrior Basin of Alabama is one of the most important coal mining and coalbed methane production areas in the United States. Methane control efforts through degasification that started almost 25 years ago for the sole purpose of ensuring mining safety resulted in more than 5000 coalbed methane wells distributed within various fields throughout the basin. The wells are completed mostly in the Pratt, Mary Lee, and Black Creek coal groups of the Upper Pottsville formation and present a unique opportunity to understand methane reservoir properties of these coals and to improve their degasification performances. The Brookwood and Oak Grove fields in the Black Warrior Basin are probably two of the most important fields in the basin due to current longwall coal mining activities. In this work, methane and water productions of 92 vertical wellbores drilled, some completed 20 years ago, over a current large coal mine district located in these two fields, were analyzed by history matching techniques. The boreholes were completed at the Mary Lee coal group, or at combinations of the Pratt, Mary Lee, and Black Creek groups. History matching models were prepared and performed according to properties of each coal group. Decline curve analyses showed that effective exponential decline rates of the wells were between 2% and 25% per year. Results of production history matching showed, although they varied by coal group, that pressure decreased as much as 80% to nearly 25 psi in some areas and resulted in corresponding decreases in methane content. Water saturation in coals decreased from 100% to between 20 and 80%, improving gas relative permeabilities to as much as 0.8. As a result of primary depletion, permeability of coal seams increased between 10 and 40% compared to their original permeability, which varied between 1 and 10 md depending on depth and coal seam. These results not only can be used for diagnostic and interpretation purposes, but can be used as parameter

    2013-07-01

    Full Text Available Bulk rock geochemistry of 169 fine-grained sediment samples of the upper Cretaceous to Paleogene Gosau Group (Northern Calcareous Alps, Austria and Slovakia from borehole and outcrop localities was performed to separate non-marine and marine deposits. Geochemical characteristics of different Gosau depositional systems, basins and sediment provenance using major-, trace-, and rare earth elements were also investigated. Geochemical proxies such as boron concentrations were tested for seeking the possibilities of paleosalinity indicators. Due to the fact that several pelagic sections are represented by extremely low boron contents, B/Al* ratios are recognized as more robust and differentiate reliably between marine (mean: 160 ± 34 and non-marine (mean: 133 ± 33 samples. Using statistical factor analysis, hemipelagic to pelagic samples from the Gießhübl Syncline and Slovakian equivalents can be differentiated from marginal-marine to non-marine samples from the Grünbach and Glinzendorf Syncline related to terrigenous (SiO2, Al2O3, K2O, Th, Rb, Zr and others and pelagic indicative elements (CaO, Sr, TOT/C and B/Al*. A clear indication for ophiolitic provenance is traced by high amounts of chromium and nickel. Only non-marine successions of the Glinzendorf Syncline show higher Cr and Ni concentrations (up to 250 and 400 ppm, respectively and enriched Cr/V and Y/Ni ratios trending to an ultramafic source.

    2006-01-01

    A geographic information system (GIS) focusing on the Upper Cretaceous Navarro and Taylor Groups in the Gulf Coast region was developed as a visual-analysis tool for the U.S. Geological Survey's 2003 assessment of undiscovered, technically recoverable oil and natural gas resources in the Western Gulf Province. The Central Energy Resources Team of the U.S. Geological Survey has also developed an Internet Map Service to deliver the GIS data to the general public. This mapping tool utilizes information from a database about the oil and natural gas endowment of the United States - including physical locations of geologic and geographic data - and converts the data into visual layers. Portrayal and analysis of geologic features on an interactive map provide an excellent tool for understanding domestic oil and gas resources for strategic planning, formulating economic and energy policies, evaluating lands under the purview of the Federal Government, and developing sound environmental policies. Assessment results can be viewed and analyzed or downloaded from the internet web site.

  18. CYMBOSPONDYLUS VERTEBRAE (ICHTHYOSAURIA, SHASTASAURIDAE FROM THE UPPER ANISIAN PREZZO LIMESTONE (MIDDLE TRIASSIC, SOUTHERN ALPS WITH AN OVERVIEW OF THE CHRONOSTRATIGRAPHIC DISTRIBUTION OF THE GROUP

    Directory of Open Access Journals (Sweden)

    MARCO BALINI

    2012-03-01

    Full Text Available Four vertebral centra from the well known fossil-bearing Prezzo Limestone (Upper Anisian, Middle Triassic at the newly discovered locality Piazza Brembana (Bergamo are described. The four bones were found exposed on the bed surface in an articulated position. Despite the incompleteness of three centra due to erosion, their otherwise fairly good preservation facilitated their study and attribution to a shastasaurid ichthyosaur. Even though the classification of isolated vertebral centra at the genus level is controversial, the presence of diapophyses truncated by the cranial margin of the centra is still considered to be diagnostic for Cymbospondylus. The new discovery comes from an ammonoid-bearing facies, which is not unusual for ichthyosaurs, and the bio-chronostratigraphic position of the Piazza Brembana bones is accurately defined by ammonoids from the lowest part of the Trinodosus Zone (Illyrian, Middle Triassic. Records of Cymbospondylus in the Southern Alps, Germanic Basin, western United States and Spitsbergen are summarized and all previous occurrences of the genus are bio-chronostratigraphically correlated by utilizing the abundant ammonoid literature. The single occurrence of Phantomosaurus neubigii is also considered, since this species is regarded in the literature as the sister taxon of Cymbospondylu. Material referred to Cymbospondylus extends from a single occurrence in the Olenekian (late Early Triassic to the Longobardian (Late Ladinian, and its stratigraphic distribution is strictly controlled by the development of basins. Within these basins the distribution of specimens appears to include relatively protected and shallow waters. Such a distribution is consistent with the mode of life of this group of ichthyosaurs as suggested by morphofunctional analysis. Cymbospondylus, like most Triassic Ichthyosaurs, probably was an undulatory swimmer, more maneuverable but slower than their Jurassic successors.

    2004-01-01

    We construct the Extended Relativity Theory in Born-Clifford-Phase spaces with an upper and lower length scales (infrared/ultraviolet cutoff). The invariance symmetry leads naturally to the real Clifford algebra Cl (2, 6, R ) and complexified Clifford Cl_C ( 4 ) algebra related to Twistors. We proceed with an extensive review of Smith's 8D model based on the Clifford algebra Cl ( 1 ,7) that reproduces at low energies the physics of the Standard Model and Gravity; including the derivation of all the coupling constants, particle masses, mixing angles, ....with high precision. Further results by Smith are discussed pertaining the interplay among Clifford, Jordan, Division and Exceptional Lie algebras within the hierarchy of dimensions D = 26, 27, 28 related to bosonic string, M, F theory. Two Geometric actions are presented like the Clifford-Space extension of Maxwell's Electrodynamics, Brandt's action related the 8D spacetime tangent-bundle involving coordinates and velocities (Finsler geometries) followed by a...

  7. EFFECT OF DE-tert-BUTYLATION AND FUNCTIONALIZATION WITH AMINE GROUPS AT THE UPPER RIM OF p-tert-BUTYLCALIX[4]ARENE TO THE EXTRACTABILITY FOR Cr3+, Cd2+ and Pb2+ IONS

    2010-06-01

    Full Text Available The effects to the extractability forwards Cr3+, Cd2+, and Pb2+ ions of de-tert-butylation and functionalization with amine groups at the upper rim of p-tert-butylcalix[4]arene had been studied by applied the p-tert-butylcalix[4]arene (1, tetrahydroxycalix[4]arene (2, and p-(aminobutoxycalixarene (3 compounds as extractants for the heavy metals ions. The extraction involved optimise of three parameters, i.e. pH, time, and concentration of extractants. The extraction degrees of the heavy metals ions at optimum conditions were compared each other to decide the effects. Compound 1 showed high extractability to Cr3+ and Pb2+ ions over Cd2+ ion, but compound 2 as the debutylated product of compound 1 showed low extractability to the all of the heavy metals ions. Compound 3 as product of etherification with butyl groups of the lower rim followed functionalization with amine groups of the upper rim of compound 1 showed high extractability to Pb2+, but low to Cr3+ and Cd2+. Pursuant to the facts it was concluded that debutylation of compound 1 to compound 2 causing decrease drastically of extractability to the heavy metals ions; functionalization of the upper with amine groups as ionophore (compound 3 causing increase of the extractability to Pb2+ ion and decrease of the extractability to Cr3+ with increasing of separation factor value β(Pb2+/Cr3+ from 1.74 by compound 1 to 48.00 by compound 3. By slope analysis, the extracted species and mechanisms of the extractions have been confirmed.   Keywords: p-tert-butylcalix[4]arene, debutylation, p-(aminobutoxycalix[4]arene, extractability, heavy metals, extraction mechanisms.

    1999-06-01

    The chronostratigraphic framework of the Campo Mourao (upper part) and Taciba formations, Itarare Group was investigated through a subsurface study in the eastern flank of the Parana Basin. A total of five depositional sequences were recognized, each represented by an upward increase in the argillaceous content (sandstone to diamictite to shale). The upper part of basal sequence 1 is formed by a thick diamictite by the Lontras Shale; these glaciomarine and marine systems may constitute the transgressive tract of the sequence and represent the top of Campo Mourao Formation/cycle. The Lontras Shale (or Member) is not restricted to the Santa Catarina State; instead it is recognized throughout the eastern flank of the basin. The sequence 2 is represented in the basal portion by the sandstones of Rio Segredo (base of Taciba Formation/cycle). The next sequences are similar to the previous one, including some particular patterns: as the basal sandstones form clastic wedges, the sequence may be represented exclusively by diamictities. The clastic wedges of sequences 2 and 4 were applied from east and northeast; the western margin also contributed as source of coarse clastics. Sequences 4 and 5 were studied in detail, since they were reached by several shallow wells near the outcrop belt. the sequence 4 clearly displays facies change from marine in the south (Passinho Shale) to delta front in center-south, and to coal-bearing delta plain in the north. The occurrence of sequence 5 is restricted to southern Parana and northern Santa Catarina; it presents deltaic sandstone deposits intercalated with marine shales/sandstones and glaciomarine diamictites. Despite some transitional characteristics shown by the upper part of Itarare Group (sequences 4 and 5), it is noteworthy the unconformable of the Group with the overlying, post-glacial Triunfo Member of Rio Bonito Formation.

    Guaifenesin, an over-the-counter (OTC) expectorant, has exhibited muscle relaxant effects preclinically and clinically. This proof-of-principle study explored whether OTC doses of guaifenesin can provide relief from acute upper back, neck, or shoulder muscle spasm and pain. This multicenter, placebo-controlled, repeat-dose, parallel study randomly assigned adults experiencing acute pain and muscle spasm in their upper back, neck, or shoulder to guaifenesin 600 or 1200 mg or matched placebo twice daily (BID) in a 2:2:1:1 ratio for 7 days. The primary end point was the change from baseline in muscle spasm relief, measured using an 11-point numeric rating scale (0=not present to 10=unbearable) recorded twice daily and averaged over the 7-day treatment period. Analyses were performed using a linear mixed model that included treatment as a fixed effect and site as a random effect. A total of 77 subjects were included in the 4 treatment groups. Least squares mean muscle spasm score over 7 days was 1.77 with guaifenesin 1200 mg, 1.42 with its matched placebo, 1.53 with guaifenesin 600 mg, and 1.74 with its matched placebo. Treatment with guaifenesin 1200 mg BID provided 25% greater reduction in mean muscle spasm over its matched placebo and 16% greater reduction than guaifenesin 600 mg BID. These differences were not statistically significant. Based on comparisons of absolute mean values, a consistent directional change in effect was observed, suggesting some benefit from placebo to lower-to-upper doses of guaifenesin with regard to muscle spasm, tension, pain, discomfort, and relaxation. No severe or serious adverse events were reported. Results suggest the potential for OTC dose of guaifenesin 1200 mg BID to provide symptomatic relief of upper back musculoskeletal pain and spasm. Confirmation of this preliminary result in a larger, adequately powered study is needed.

Over 10,000 patients receive PD in the United States [United States Renal Data System: 2015 USRDS Annual Data Report: Epidemiology of Kidney Disease in the United States, 2015]. PD has superior outcomes compared to hemodialysis in the first 2 years of ESRD [Sinnakirouchenan and Holley: Adv Chronic Kidney Dis 2011;18: 428-432]. However, peritonitis is a known complication and may result in significant morbidity and necessitate transition to hemodialysis, which increases medical costs [Holley and Piraino: Semin Dial 1990;3: 245-248]. We report the first case of a PD patient who underwent endoscopy, colonoscopy and CT angiogram with coil embolization for gastrointestinal bleeding without antibiotic prophylaxis and subsequently developed CDC group EO-4 organism and fungal peritonitis.

    The Jurassic Smackover Interior Salt Basins Total Petroleum System is defined for this assessment to include (1) Upper Jurassic Smackover Formation carbonates and calcareous shales and (2) Upper Jurassic and Lower Cretaceous Cotton Valley Group organic-rich shales. The Jurassic Smackover Interior Salt Basins Total Petroleum System includes four conventional Cotton Valley assessment units: Cotton Valley Blanket Sandstone Gas (AU 50490201), Cotton Valley Massive Sandstone Gas (AU 50490202), Cotton Valley Updip Oil and Gas (AU 50490203), and Cotton Valley Hypothetical Updip Oil (AU 50490204). Together, these four assessment units are estimated to contain a mean undiscovered conventional resource of 29.81 million barrels of oil, 605.03 billion cubic feet of gas, and 19.00 million barrels of natural gas liquids. The Cotton Valley Group represents the first major influx of clastic sediment into the ancestral Gulf of Mexico. Major depocenters were located in south-central Mississippi, along the Louisiana-Mississippi border, and in northeast Texas. Reservoir properties and production characteristics were used to identify two Cotton Valley Group sandstone trends across northern Louisiana and east Texas: a high-permeability blanket-sandstone trend and a downdip, low-permeability massive-sandstone trend. Pressure gradients throughout most of both trends are normal, which is characteristic of conventional rather than continuous basin-center gas accumulations. Indications that accumulations in this trend are conventional rather than continuous include (1) gas-water contacts in at least seven fields across the blanket-sandstone trend, (2) relatively high reservoir permeabilities, and (3) high gas-production rates without fracture stimulation. Permeability is sufficiently low in the massive-sandstone trend that gas-water transition zones are vertically extensive and gas-water contacts are poorly defined. The interpreted presence of gas-water contacts within the Cotton Valley

    Full Text Available Introduction : There is increasing interest in sedation for upper gastrointestinal endoscopy (UGE. Prospective randomized studies comparing sedation properties and complications of propofol and midazolam/meperidine in upper gastrointestinal endoscopy (UGE are few. Aim: To compare propofol and midazolam/meperidine sedation for UGE in terms of cardiopulmonary side effects, patient and endoscopist satisfaction and procedure-related times. Material and methods: This was a prospective, randomized, double-blind study of propofol versus midazolam and meperidine in 100 patients scheduled for diagnostic upper gastrointestinal endoscopy. The patients were divided into propofol and midazolam/meperidine groups. Randomization was generated by a computer. Cardiopulmonary side effects (hypotension, bradycardia, hypoxemia, procedure-related times (endoscopy time, awake time, time to hospital discharge, and patient and endoscopist satisfaction were compared between groups. Results: There was no significant difference between the groups with respect to the cost, endoscopy time, or demographic and clinical characteristics of the patients. Awake time and time to hospital discharge were significantly shorter in the propofol group (6.58 ±4.72 vs. 9.32 ±4.26 min, p = 0.030 and 27.60 ±7.88 vs. 32.00 ±10.54 min, p = 0.019. Hypotension incidence was significantly higher in the propofol group (12% vs. 0%, p = 0.027. The patient and endoscopist satisfaction was better with propofol. Conclusions : Propofol may be preferred to midazolam/meperidine sedation, with a shorter awake and hospital discharge time and better patient and endoscopist satisfaction. However, hypotension risk should be considered with propofol, and careful evaluation is needed, particularly in cardiopulmonary disorders.

    In 2010, the U.S. Geological Survey (USGS) assessed Lower Cretaceous Albian to Upper Cretaceous Cenomanian carbonate rocks of the Fredericksburg and Washita Groups and their equivalent units for technically recoverable, undiscovered hydrocarbon resources underlying onshore lands and State Waters of the Gulf Coast region of the United States. This assessment was based on a geologic model that incorporates the Upper Jurassic-Cretaceous-Tertiary Composite Total Petroleum System (TPS) of the Gulf of Mexico basin; the TPS was defined previously by the USGS assessment team in the assessment of undiscovered hydrocarbon resources in Tertiary strata of the Gulf Coast region in 2007. One conventional assessment unit (AU), which extends from south Texas to the Florida panhandle, was defined: the Fredericksburg-Buda Carbonate Platform-Reef Gas and Oil AU. The assessed stratigraphic interval includes the Edwards Limestone of the Fredericksburg Group and the Georgetown and Buda Limestones of the Washita Group. The following factors were evaluated to define the AU and estimate oil and gas resources: potential source rocks, hydrocarbon migration, reservoir porosity and permeability, traps and seals, structural features, paleoenvironments (back-reef lagoon, reef, and fore-reef environments), and the potential for water washing of hydrocarbons near outcrop areas.In Texas and Louisiana, the downdip boundary of the AU was defined as a line that extends 10 miles downdip of the Lower Cretaceous shelf margin to include potential reef-talus hydrocarbon reservoirs. In Mississippi, Alabama, and the panhandle area of Florida, where the Lower Cretaceous shelf margin extends offshore, the downdip boundary was defined by the offshore boundary of State Waters. Updip boundaries of the AU were drawn based on the updip extent of carbonate rocks within the assessed interval, the presence of basin-margin fault zones, and the presence of producing wells. Other factors evaluated were the middle

    The authors report a retrospective assessment of late xerostomia according to the RTOG (Radiation Therapy Oncology Group) classification of the European Organization for Research and Treatment of Cancer (EORTC) among patients treated by intensity-modulated conformational radiotherapy (IMRT) and suffering from upper aero-digestive tract carcinomas of different stages. Some of these patients have bee operated, and some have been treated by chemotherapy. It appears that the IMRT results in a reduction of late xerostomia, and even in an absence of salivary toxicity.

    The aim of this research was to verify the amount of horizontal and vertical movement and incisor inclination of upper incisors and correlate these with Edgewise and Alexander brackets use and the presence of overbite during anterior retraction in sliding mechanics. The sample was composed of 40 adult patients divided into 2 groups, treated with Edgewise and Alexander brackets (20 each) subdivided in 2 groups (10 each), according to the presence or absence of deep bite. Treatment consisted of 4 extraction cases with sliding mechanics with the 2 different brackets. Pre- and post-treatment cephalograms were measured and the values of interest submitted to descriptive statistical analysis, ANOVA at 5%, the Tukey test and Pearson's correlation. Upper incisor retraction was not related to the brackets used nor to the presence of deep bite, though lingual tipping was greater when Edgewise brackets were used and deep bite was absent. No statistically significant differences in upper incisor vertical movements were observed and no correlation was determined between upper incisor intrusion and lower incisor labial tipping in overbite correction or in upper incisor retraction and lower incisor labial tipping for overjet correction. Bracket prescription and its interaction with deep bite were significant and Edgewise brackets without deep bite showed the worst inclination control. It was concluded that bracket prescriptions are important to increase control of sliding mechanics.

    Full Text Available Al norte del lago Los Barreales aflora el tramo superior de la Formación Portezuelo, unidad basal del Subgrupo Río Neuquén (Grupo Neuquén del Turoniano superior-Coniaciano. En ese sector se realizaron estudios sedimentológicos para determinar los paleoambientes sedimentarios, su evolución y determinar los factores de control más relevantes.Se determinaron 12 litofacies que fueron incluidas en 6 asociaciones de facies. La naturaleza y organización de las asociaciones, permiten el desarrollo de canales fluviales entrelazados gravosos y de carga mixta de baja y alta sinuosidad. Las paleocorrientes son, en general, hacia NE y NO.Los sistemas fluviales estuvieron sujetos a cambios abruptos en el régimen de descarga correlacionables con variables climáticas de corto término. Las variaciones en el tamaño de grano dominante de la carga de lecho, espesores de los cuerpos de canal y proporciones relativas de elementos de canal/llanura de inundación, responden a fluctuaciones de largo término en los niveles de descarga. También se interpreta que las modificaciones en el nivel de base controlaron la arquitectura fluvial a gran escala. El apilamiento de las unidades de canal, se relaciona con una tasa de suministro que no pudo ser, en general, compensada por la tasa de subsidencia. Un ligero incremento de ésta última hacia el tope de la unidad, dio como resultado el desarrollo de áreas anegadas dentro de la llanura de inundación y cuerpos de agua más o menos estables que fueron luego ocupadas por un sistema fluvial de carga mixta de alta sinuosidad.The upper part of the Portezuelo Formation (upper Turonian-Coniacian; Río Neuquen Subgroup of the Neuquen Group crops out to the north of the Los Barreales lake.

    [Purpose] In this study, we compared upper cervical flexion and cervical flexion angle of computer workers with upper trapezius and levator scapular pain. [Subject] Eight male computer workers with upper trapezius muscle pain and eight others with levator scapular muscle pain participated. [Methods] Each subject was assessed in terms of upper cervical flexion angle and total cervical flexion angles using a cervical range of motion instrument after one hour of computer work. [Results] The upper cervical flexion angle of the group with levator scapular pain was significantly lower than that of the group with upper trapezius pain after computer work. The total cervical flexion angle of the group with upper trapezius pain was significantly lower than that of the group with levator scapular pain after computer work. [Conclusion] For selective and effective intervention for neck pain, therapists should evaluate upper and lower cervical motion individually.

    Pathomimia, or factitious disorders, are characterized by producing symptoms voluntarily with the intention of playing the role of the patient. Inspite of being considerd as a psychatric disorder, pathomimuia is often encountered in the daily professional life of doctors without being recognized or diagnosed. There are various clinical aspects of pathomimia. The items that decide the orientation of the diagnosis are essentially the uncommon and odd expression of the reported symptoms, A capricious evolution as well as the multiplicity of the past medical cases. We report a group of five patients who were followed and treated between the years 2000 and 2003. This group was composed of three men and two women with an average age of 30 years. In three cases, we found the notion of skin injury. In one case, we noted a median nerve lesion in the elbow and once in the right upper member. The evolution was performed towards recidives of the initial symptomatology with more or less long periods of improvements.

    Transconjunctival lower lid blepharoplasty now has an established role as an option in rejuvenation of the lower eyelid. Transconjunctival upper lid blepharoplasty, or transconjunctival removal of medial upper eyelid fat, also has a role in rejuvenation of the upper eyelid. However, this is a rather limited role. We have found this approach safe and efficacious as a primary as well as a secondary procedure for removal of excess medial upper eyelid fat. We report on 20 patients who have undergone this operation: 5 as a primary procedure and 15 as secondary. There were no complications, no revisions, and the patients have been uniformly happy with their results.

    Nonvariceal upper gastrointestinal bleeding (NUGB) remains a major medical problem even after advances in medical therapy with gastric acid suppression and cyclooxygenase (COX-2) inhibitors. Although the incidence of upper gastrointestinal bleeding presenting to the emergency room has slightly decreased, similar decreases in overall mortality and rebleeding rate have not been experienced over the last few decades. Many causes of upper gastrointestinal bleeding have been identified and will be reviewed. Endoscopic, radiographic and angiographic modalities continue to form the basis of the diagnosis of upper gastrointestinal bleeding with new research in the field of CT angiography to diagnose gastrointestinal bleeding. Endoscopic and angiographic treatment modalities will be highlighted, emphasizing a multi-modality treatment plan for upper gastrointestinal bleeding. (orig.)

    Compared to lower limb arterial diseases, upper limb arterial diseases look rare, heterogeneous with various etiologies and a rather vague clinical picture, but with a negligible risk of amputation. Almost all types of arterial diseases can be present in the upper limb, but the anatomical and hemodynamic conditions particular to the upper limb often confuse the issue. Thus, atherosclerosis affects mainly the subclavian artery in its proximal segment where the potential of collateral pathway is high making the symptomatic forms not very frequent whereas the prevalence of subclavian artery stenosis or occlusion is relatively high. The clinical examination and the etiologies are discussed according to the clinical, anatomical and hemodynamic context.

    In the intensive care unit, vigilance is needed to manage nonvariceal upper gastrointestinal bleeding. A focused history and physical examination must be completed to identify inciting factors and the need for hemodynamic stabilization. Although not universally used, risk stratification tools such as the Blatchford and Rockall scores can facilitate triage and management. Urgent evaluation for nonvariceal upper gastrointestinal bleeds requires prompt respiratory assessment, and identification of hemodynamic instability with fluid resuscitation and blood transfusions if necessary. Future studies are needed to evaluate the indication, safety, and efficacy of emerging endoscopic techniques. Copyright © 2016 Elsevier Inc. All rights reserved.

    Reconstruction of the upper eyelid is complicated because the eyelid must retain mobility, flexibility, function, and a suitable mucosal surface over the delicate cornea. Defects of the upper eyelid may be due to congenital defects or traumatic injury or follow oncologic resection. This article focuses on reconstruction due to loss of tissue. Multiple surgeries may be needed to reach the desired results, addressing loss of tissue and then loss of function. Each defect is unique and the laxity and availability of surrounding tissue vary. Knowing the most common techniques for repair assists surgeons in the multifaceted planning that takes place.

    2015-12-01

    The Neoproterozoic Era was a time of extreme climatic variation as recorded in sedimentary rocks of this age across the globe, leading to a number of controversial hypotheses (e.g. the Snowball Earth glaciations). In eastern Brazil, the Bambuí Gr. is a thick carbonatic-siliciclastic unit that covers the São Francisco Craton and preserves remnants of a Neoproterozoic glaciation and their respective cap carbonate (1). Recent findings of Cloudina in the Januária region (2) suggest that at least part of the sequence might be upper Ediacaran or even Cambrian. Here we present the first carbon-oxygen isotope data for the Jaíba Fm., a ca. 50 m thick carbonate unit that occurs in the topmost portion of the Bambuí Gr. in this same region. The Jaíba Fm. post-dates the cap carbonate sequence and the fossil-bearing layers, and thus was probably deposited in the Ediacaran-Cambrian transition. Three stratigraphic columns were analyzed, and yielded similar ratios. Values of δ13CVPDB are between 0.8 and 3.4 ‰, while δ18OVPDB values are mostly around -8 ‰. These values contrasts with the negative δ13C values found for the base of the Bambuí Gr., followed by highly positive δ13C (up to +14‰) on its middle portion. The unusually high δ13C values are commonly interpreted as evidence for deposition on a restricted basin, such as in a foreland setting. The return to values which are close to the PDB standard in the uppermost Bambuí Gr. might thus indicate a change in the paleogeography and tectonic environment of the basin, suggesting an open, ventilated environment along with a recovery of the biological and hydrological cycle after a Late Neoproterozoic glaciation. Ongoing detailed sedimentological, geochemical and isotopic work might help to further clarify these issues and to provide new clues for unraveling Late Neoproterozoic paleoclimate, paleogeography and ocean chemistry.

    2015-10-01

    Acute upper gastrointestinal bleeding (AUGIB) is a frequently encountered medical emergency with an incidence of 84-160/100000 and associated with mortality of approximately 10%. Guidelines from the National Institute for Care and Care Excellence outline key features in the management of AUGIB. Patients require prompt resuscitation and risk assessment using validated tools. Upper gastrointestinal endoscopy provides accurate diagnosis, aids in estimating prognosis and allows therapeutic intervention. Endoscopy should be undertaken immediately after resuscitation in unstable patients and within 24 hours in all other patients. Interventional radiology may be required for bleeding unresponsive to endoscopic intervention. Drug therapy depends on the cause of bleeding. Intravenous proton pump inhibitors should be used in patients with high-risk ulcers. Terlipressin and broad-spectrum antibiotics should be used following variceal haemorrhage. Hospitals admitting patients with AUGIB need to provide well organised services and ensure access to relevant services for all patients, and particularly to out of hours endoscopy. © Royal College of Physicians 2015.

    2015-06-01

    Nordic research on physiology and pathophysiology of the upper gastrointestinal tract has flourished during the last 50 years. Swedish surgeons and physiologists were in the frontline of research on the regulation of gastric acid secretion. This research finally led to the development of omeprazole, the first proton pump inhibitor. When Swedish physiologists developed methods allowing the assessment of acid secretion in isolated oxyntic glands and isolated parietal cells, the understanding of mechanisms by which gastric acid secretion is regulated took a great step forward. Similarly, in Trondheim, Norway, the acid producing isolated rat stomach model combined with a sensitive and specific method for determination of histamine made it possible to evaluate this regulation qualitatively as well as quantitatively. In Lund, Sweden, the identification of the enterochromaffin-like cell as the cell taking part in the regulation of acid secretion by producing and releasing histamine was of fundamental importance both physiologically and clinically. Jorpes and Mutt established a center at Karolinska Institutet in Stockholm for the purification of gastrointestinal hormones in the 1960s, and Danes followed up this work by excelling in the field of determination and assessment of biological role of gastrointestinal hormones. A Finnish group was for a long period in the forefront of research on gastritis, and the authors' own studies on the classification of gastric cancer and the role of gastrin in the development of gastric neoplasia are of importance. It can, accordingly, be concluded that Nordic researchers have been central in the research on area of the upper gastrointestinal physiology and diseases.

    1997-01-01

    Herbaceous lycopsids are often overlooked in palaeobotanical studies because of problems of morphological interpretation and identification. The literature on Euramerican Upper Carboniferous herbaceous lycopsids is reviewed on those species referred to the genera Selaginellites, Lycopodites, Paurodendron, Carinostrobus, Miadesmia, Spencerites and the identification of some specimens is challenged. The stratigraphical range of these lycopsids and those of dispersed spores referable to them are also reviewed and suggestions are given for the relatively late appearance of many of these lycopsids in the Euramerican Coal Measures swamps. It is suggested that anisophyllous Selaginella-like lycopsids made their first appearance in the Bolsovian (ex Westphalian C) of the Saar-Lorraine intramontane basin. Evidence from studies of coal balls and dispersed spore assemblages confirm that herbaceous lycopsids were most abundantly present in open-moor communities. Certain species of these herbaceous lycopsids, the Selaginella-like ones, are included within the extant genus Selaginella Linnaeus. For this reason a number of new combinations are proposed.

    教学关系论角度的“学习投入”理论主张从行为投入、情感投入与认知投入三个维度对学习过程进行探讨。本文基于学习投入理论,对日语专业学情调查数据进行分析发现:上游学习者与下游学习者在行为投入、情感投入和认知投入上存在着明显的差异。表明学习投入三个维度(行为、情感和认知)与学习者的学业水平之间存在着重要的相关关系。换言之,两组学习者在各维度上表现出的差异可能是他们之间学业水平分层加剧的重要原因之一。%Learning engagement theory advocates exploring the learning process from three dimensions: behavioral, emotional and cognitive engagement. Based on the theory, the paper analyzes the data collected in the survey of Japanese majors. The analysis tells us that there is a significant difference in the behavioral, emotional and cognitive engagement between the upper level students and lower level students. It also shows that there is a positive correlation between students’ engagement in the three dimensions and their academic achievements. We can say that their difference in engagement is one of the important reasons for their difference in academic performance.

  12. Upper bounds for centerlines

    CERN Document Server

    Bukh, Boris

    2011-01-01

    In 2008, Bukh, Matousek, and Nivasch conjectured that for every n-point set S in R^d and every k, 0 <= k <= d-1, there exists a k-flat f in R^d (a "centerflat") that lies at "depth" (k+1) n / (k+d+1) - O(1) in S, in the sense that every halfspace that contains f contains at least that many points of S. This claim is true and tight for k=0 (this is Rado's centerpoint theorem), as well as for k = d-1 (trivial). Bukh et al. showed the existence of a (d-2)-flat at depth (d-1) n / (2d-1) - O(1) (the case k = d-2). In this paper we concentrate on the case k=1 (the case of "centerlines"), in which the conjectured value for the leading constant is 2/(d+2). We prove that 2/(d+2) is an *upper bound* for the leading constant. Specifically, we show that for every fixed d and every n there exists an n-point set in R^d for which no line in R^d lies at depth larger than 2n/(d+2) + o(n). This point set is the "stretched grid"---a set which has been previously used by Bukh et al. for other related purposes.

  13. Upper airway resistance syndrome.

    Montserrat, J M; Badia, J R

    1999-03-01

    This article reviews the clinical picture, diagnosis and management of the upper airway resistance syndrome (UARS). Presently, there is not enough data on key points like the frequency of UARS and the morbidity associated with this condition. Furthermore, the existence of LIARS as an independent sleep disorder and its relation with snoring and obstructive events is in debate. The diagnosis of UARS is still a controversial issue. The technical limitations of the classic approach to monitor airflow with thermistors and inductance plethysmography, as well as the lack of a precise definition of hypopnea, may have led to a misinterpretation of UARS as an independent diagnosis from the sleep apnea/hypopnea syndrome. The diagnosis of this syndrome can be missed using a conventional polysomnographic setting unless appropriate techniques are applied. The use of an esophageal balloon to monitor inspiratory effort is currently the gold standard. However, other sensitive methods such as the use of a pneumotachograph and, more recently, nasal cannula/pressure transducer systems or on-line monitoring of respiratory impedance with the forced oscillation technique may provide other interesting possibilities. Recognition and characterization of this subgroup of patients within sleep breathing disorders is important because they are symptomatic and may benefit from treatment. Management options to treat UARS comprise all those currently available for sleep apnea/hypopnea syndrome (SAHS). However, the subset of patients classically identified as LIARS that exhibit skeletal craneo-facial abnormalities might possibly obtain further benefit from maxillofacial surgery.

    Full Text Available Schwannomas are the commonest tumours of peripheral nerves. Despite the classical description that schwannomas are well encapsulated and can be completely enucleated during excision, a portion of them have fascicular involvement and could not be completely shelled out. A retrospective review for 8 patients was carried out over 10 years. 75% of schwannoma occurred over the distal region of upper limb (at elbow or distal to it. It occurs more in the mixed nerve instead of pure sensory or motor nerve. 50% of patients had mixed nerve involvement. Fascicular involvement was very common in schwannoma (75% of patients. Removal of the tumour with fascicles can cause functional deficit. At present, there is no method (including preoperative MRI which can predict the occurrence of fascicular involvement; the authors therefore proposed a new system to stratify patients who may benefit from interfascicular nerve grafts. In this group of patients, the authors strongly recommend that the possibility and option of nerve graft should be discussed with patients prior to schwannoma excision, so that nerve grafting could be directly proceeded with patient consent in case there is fascicular involvement of tumour found intraoperatively.

    To distinguish upper from lower gastrointestinal (GI) bleeding. Patient records between April 2011 and March 2014 were analyzed retrospectively (3296 upper endoscopy, and 1520 colonoscopy). Seventy-six patients had upper GI bleeding (Upper group) and 65 had lower GI bleeding (Lower group). Variables were compared between the groups using one-way analysis of variance. Logistic regression was performed to identify variables significantly associated with the diagnosis of upper vs lower GI bleeding. Receiver-operator characteristic (ROC) analysis was performed to determine the threshold value that could distinguish upper from lower GI bleeding. Hemoglobin (P = 0.023), total protein (P = 0.0002), and lactate dehydrogenase (P = 0.009) were significantly lower in the Upper group than in the Lower group. Blood urea nitrogen (BUN) was higher in the Upper group than in the Lower group (P = 0.0065). Logistic regression analysis revealed that BUN was most strongly associated with the diagnosis of upper vs lower GI bleeding. ROC analysis revealed a threshold BUN value of 21.0 mg/dL, with a specificity of 93.0%. The threshold BUN value for distinguishing upper from lower GI bleeding was 21.0 mg/dL.

    2006-03-01

    We sought to establish the feasibility of measuring upper airway narrowing in spontaneously breathing, anesthetized children using dynamic application of negative airway pressure. A secondary aim was to compare differences in upper airway collapsibility after the administration of sevoflurane or halothane. Subjects were randomized to either drug for inhaled anesthetic induction. Each was adjusted to their 1 MAC value (0.9% for halothane and 2.5% for sevoflurane) and a blinded anesthesia provider held the facemask without performing manual airway opening maneuvers but with inclusion of an oral airway device. Inspiratory flows were measured during partial upper airway obstruction created by an adjustable negative pressure-generating vacuum motor inserted into the anesthesia circuit. Critical closing pressure of the pharynx (Pcrit) was obtained by plotting the peak inspiratory flow of the obstructed breaths against the corresponding negative pressure in the facemask and extrapolating to zero airflow using linear correlation. Fourteen children were enrolled, seven in each anesthetic group. Two children in the halothane group did not develop flow-limited airway obstruction despite negative pressures as low as -9 cm H2O. Pcrit for sevoflurane ranged from -6.7 to -11.6 (mean +/- sd, -9.8 +/- 1.9) cm H2O. Pcrit for halothane ranged from -8.1 to -33 (mean +/- sd, -19.4 +/- 9.3) cm H2O (sevoflurane versus halothane, P = 0.048). We conclude that when using dynamic application of negative airway pressure, halothane appears to cause less upper airway obstruction than sevoflurane at equipotent concentrations.

    2007-06-01

    Monomelic amyotrophy (MA) is a rare condition in which neurogenic amyotrophy is restricted to an upper or lower limb. Usually sporadic, it usually has an insidious onset with a mean evolution of 2 to 4 years following first clinical manifestations, which is, in turned, followed by stabilization. We report a case of 20-years-old man who presented slowly progressive amyotrophy associated with proximal paresis of the right upper limb, which was followed by clinical stabilization 4 years later. Eletroneuromyography revealed denervation along with myofasciculations in various muscle groups of the right upper limb. We call attention to this rare location of MA, as well as describe some theories concerning its pathophysiology .

    We give an upper bound on the size of short conjugators in certain solvable groups. Diestel-Leader graphs, which are a horocyclic product of trees, are discussed briefly and used to study the lamplighter groups. The other solvable groups we look at can be recognised in a similar vein, as groups which act on a horocyclic product of well known spaces. These include the Baumslag-Solitar groups BS(1,q) and semidirect products of Z^n with Z^k. Results can also be applied to the conjugacy of parabolic elements in Hilbert modular groups and to elements in 3-manifold groups.

    Sarcoidosis is a chronic granulomatous disease of unknown aetiology. It can affect any part of the organism, although the lung is the most frequently affected organ. Upper airway involvement is rare, particularly if isolated. Sarcoidosis is a diagnosis of exclusion, established by histological evidence of non-caseating granulomas and the absence of other granulomatous diseases. The authors report a case of a man with sarcoidosis manifesting as a chronic inflammatory stenotic condition of the upper respiratory tract and trachea.

    Upper extremity amputations are most frequently indicated by severe traumatic injuries. The location of the injury will determine the level of amputation. Preservation of extremity length is often a goal. The amputation site will have important implications on the functional status of the patient and options for prosthetic reconstruction. Advances in amputation techniques and prosthetic reconstructions promote improved quality of life. In this article, the authors review the principles of upper extremity amputation, including techniques, amputation sites, and prosthetic reconstructions.

  6. Prognosis following upper gastrointestinal bleeding.

    Directory of Open Access Journals (Sweden)

    Stephen E Roberts

    Full Text Available BACKGROUND: Upper gastrointestinal (GI bleeding is one of the most common, high risk emergency disorders in the western world. Almost nothing has been reported on longer term prognosis following upper GI bleeding. The aim of this study was to establish mortality up to three years following hospital admission with upper GI bleeding and its relationship with aetiology, co-morbidities and socio-demographic factors. METHODS: Systematic record linkage of hospital inpatient and mortality data for 14 212 people in Wales, UK, hospitalised with upper GI bleeding between 1999 and 2004 with three year follow-up to 2007. The main outcome measures were mortality rates, standardised mortality ratios (SMRs and relative survival. RESULTS: Mortality at three years was 36.7% overall, based on 5215 fatalities. It was highest for upper GI malignancy (95% died within three years and varices (52%. Compared with the general population, mortality was increased 27-fold during the first month after admission. It fell to 4.3 by month four, but remained significantly elevated during every month throughout the three years following admission. The most important independent prognostic predictors of mortality at three years were older age (mortality increased 53 fold for people aged 85 years and over compared with those under 40 years; oesophageal and gastric/duodenal malignancy (48 and 32 respectively and gastric varices aetiologies (2.8 when compared with other bleeds; non-upper GI malignancy, liver disease and renal failure co-morbidities (15, 7.9 and 3.9; social deprivation (29% increase for quintile V vs I; incident bleeds as an inpatient (31% vs admitted with bleeding and male patients (25% vs female. CONCLUSION: Our study shows a high late as well as early mortality for upper GI bleeding, with very poor longer term prognosis following bleeding due to malignancies and varices. Aetiologies with the worst prognosis were often associated with high levels of social

    Upper gastrointestinal (GI) hemorrhage is a serious complication of coronary artery bypass grafting (CABG). The aim of this study was to retrospectively investigate the risk factors and prevention of upper GI bleeding after CABG. This study followed 6316 coronary patients who underwent CABG from 1998 to 2005. The perioperative parameters were recorded. Data from patients who experienced major gastrointestinal complications were analyzed retrospectively by univariate and multivariate analyses. The rate of upper GI bleeding was 0.3%. The overall mortality for patients complicated by upper GI bleeding was 47.6%. The risk factors for upper GI bleeding were age (odds ratio [OR] = 3.18, 95% confidence interval [CI] = 1.73-5.87, P upper GI bleeding group and the controls (P risk factors for upper GI bleeding after CABG, and the prophylactic use of omeprazole decreased the rate of upper GI bleeding.

    1991-01-01

    Arterial surgery of the upper limb represents 2.5% of peripheral vascular procedures in our center. From 1976 to 1989, 58 procedures were performed in 45 patients. There were 26 men and 19 women with average age of 52 years, ranging from 6 to 92 years. These patients were grouped in three categories according to etiology: 1) trauma; 2) acute non traumatic ischemia and 3) chronic ischemia. Sixteen patients (35.5%) were operated on for arterial trauma including three false aneurysms. Blunt trauma was the cause in 9 patients, penetrating in 6 and iatrogenic in one. Angioplasty and primary end to end anastomosis were used in 6, bypass in 4, simple ligation in 3, thrombectomy in 3. The outcome was excellent in 15/16 (93%). Non traumatic acute ischemia occurred in 16 patients (35.5%) and was due to emboli of cardiac origin in 92%. All patients were treated by thromboembolectomy. This group had a high mortality (5/16, 31%) because of associated medical conditions. The third group of 13 patients (29%) underwent surgery for chronic ischemia of the upper limb localized to the subclavian artery in 92%. They were treated with carotid subclavian bypasses in 9, other types of bypass in 3 and endarterectomy in 1. Excellent results were obtained in 10/13 (78%). Overall, satisfactory results were obtained in 90% of surviving patients. Operative mortality was 11.1% and the amputation rate was 13%.

    Nine cases of plasmocytoma of the upper airways in the current biopsy material are studied over a three-year period (1991-1993). Initially, all nine cases are clinically diagnosed as neoplasms: hemangiofibroma--one, chondrosarcoma--one, suspected carcinoma--five, and unspecified diagnosis--two. "Plasmocytoma" diagnosis is made on the ground of histological investigation of the material, supported histochemically and electron-microscopically. Some diagnostic problems (differential diagnosis inclusive) are discussed, as well as issues relating to the clinical and morphological evolution of the disease, and predilected gender and age groups.

    We prove that the (normalized) Lusternik-Schnirelmann category of the symplectic group Sp(n) is less or equal to [(n+2)^2/4]-1. Our techniques are Lie theoretic and can easily be generalized to find upper bounds for the Lusternik-Schnirelmann category of any simply connected compact Lie group. We conjecture that our upper bounds are sharp.

    Klein, Amir; Gralnek, Ian M

    2015-04-01

    Acute, nonvariceal upper gastrointestinal bleeding (UGIB) is a common medical emergency encountered worldwide. Despite medical and technological advances, it remains associated with significant morbidity and mortality. Rapid patient assessment and management are paramount. When indicated, upper endoscopy in patients presenting with acute UGIB is effective for both diagnosis of the bleeding site and provision of endoscopic hemostasis. Endoscopic hemostasis significantly reduces rebleeding rates, blood transfusion requirements, length of hospital stay, surgery, and mortality. Furthermore, early upper endoscopy, defined as being performed within 24 h of patient presentation, improves patient outcomes. A structured approach to the patient with acute UGIB that includes early hemodynamic resuscitation and stabilization, preendoscopic risk stratification using validated instruments, pharmacologic and endoscopic intervention, and postendoscopy therapy is important to optimize patient outcome and assure efficient use of medical resources.

    2011-12-01

    The paper deals with controlling an upper limb prosthesis based on the measurement of myoelectric signals (MES) while drinking. MES signals have been measured on healthy limbs to obtain the same response for the prosthesis. To simulate the drinking motion of a healthy upper limb, the program ADAMS was used, with all degrees of freedom and a hand after trans-radial amputation with an existing hand prosthesis. Modification of the simulation has the exact same logic of control, where the muscle does not have to be strenuous all the time, but it is the impulse of the muscle which drives the motor even though the impulse disappears and passed away.

    Hand surgeons routinely treat carpal and cubital tunnel syndromes, which are the most common upper extremity nerve compression syndromes. However, more infrequent nerve compression syndromes of the upper extremity may be encountered. Because they are unusual, the diagnosis of these nerve compression syndromes is often missed or delayed. This article reviews the causes, proposed treatments, and surgical outcomes for syndromes involving compression of the posterior interosseous nerve, the superficial branch of the radial nerve, the ulnar nerve at the wrist, and the median nerve proximal to the wrist.

    2013-01-01

    To survey participants at various experience levels of different martial arts (MA) about upper extremity injuries sustained during training and fighting. A 21-s question survey was designed and utilised. The survey was divided into four groups (Demographics, Injury Description, Injury Mechanism, and Miscellaneous information) to gain knowledge about upper extremity injuries sustained during martial arts participation. Chi-square testing was utilised to assess for significant associations. Males comprised 81% of respondents. Involvement in multiple forms of MA was the most prevalent (38%). The hand/wrist was the most common area injured (53%), followed by the shoulder/upper arm (27%) and the forearm/elbow (19%). Joint sprains/muscle strains were the most frequent injuries reported overall (47%), followed by abrasions/bruises (26%). Dislocations of the upper extremity were reported by 47% of participants while fractures occurred in 39%. Surgeries were required for 30% of participants. Females were less likely to require surgery and more likely to have shoulder and elbow injuries. Males were more likely to have hand injuries. Participants of Karate and Tae Kwon Do were more likely to have injuries to their hands, while participants of multiple forms were more likely to sustain injuries to their shoulders/upper arms and more likely to develop chronic upper extremity symptoms. With advanced level of training the likelihood of developing chronic upper extremity symptoms increases, and multiple surgeries were required. Hand protection was associated with a lower risk of hand injuries. Martial arts can be associated with substantial upper extremity injuries that may require surgery and extended time away from participation. Injuries may result in chronic upper extremity symptoms. Hand protection is important for reducing injuries to the hand and wrist.

    This project is currently under contract for research through the Department of Homeland Security until 2011. The group I was responsible for studying has to remain confidential so as not to affect the current project. All dates, reference links and authors, and other distinguishing characteristics of the original group have been removed from this report. All references to the name of this group or the individual splinter groups has been changed to 'Group X'. I have been collecting texts from a variety of sources intended for the use of recruiting and radicalizing members for Group X splinter groups for the purpose of researching the motivation and intent of leaders of those groups and their influence over the likelihood of group radicalization. This work included visiting many Group X websites to find information on splinter group leaders and finding their statements to new and old members. This proved difficult because the splinter groups of Group X are united in beliefs, but differ in public opinion. They are eager to tear each other down, prove their superiority, and yet remain anonymous. After a few weeks of intense searching, a list of eight recruiting texts and eight radicalizing texts from a variety of Group X leaders were compiled.

    1988-03-01

    The Upper Pennsylvanian (Conemaugh Group) Duquesne Coal west of Steubenville, Ohio represents a deltaic peat-accumulating swamp, and is one the best known of coal swamp floras. In a few places, the peat was infiltrated and permineralized by calcium carbonate prior to coalification, thus producing coal balls in which both morphological and anatomical structure of the constituent plant parts are preserved. The plant material represents primarily the community that inhabited the peat-accumulating environment, but some remains from near-swamp environments also are represented. The flora is relatively diverse, consisting of over 55 megafossil taxa of isolated organs that were produced by at least 25 species of plants. All five major groups of Pennsylvanian coal-swamp plants (i.e. Lycopsida, Sphenopsida, Pteridopsida, Pteridospermopsida and Cordaitales) are represented. 31 refs., 2 figs.

    2006-06-01

    To assess the outcome of orthodontic treatment with upper jaw or upper and lower jaw extraction for Class II division 1 malocclusion using the peer assessment rating (PAR) index. 28 patients with Class II division 1 were extracted two first premolars or second premolars of upper jaw, and 24 patients were extracted four premolars of upper and lower jaw N. The PAR was applied on pre-and post-orthodontic treatment dental casts for the fifty-two cases. The upper and lower jaw extraction groups had significantly higher initial PAR scores and the weighted PAR total scores (P0.05). The upper and lower jaw extraction cases showed more severe dental displacement. Both treatment can acquire successful results.

    Stroke survivors with hemiparesis and spinal cord injury (SCI) survivors with tetraplegia find it difficult or impossible to perform many activities of daily life. There is growing evidence that intensive exercise therapy, especially when supplemented with functional electrical stimulation (FES), can improve upper extremity function, but delivering the treatment can be costly, particularly after recipients leave rehabilitation facilities. Recently, there has been a growing level of interest among researchers and healthcare policymakers to deliver upper extremity treatments to people in their homes using in-home teletherapy (IHT). The few studies that have been carried out so far have encountered a variety of logistical and technical problems, not least the difficulty of conducting properly controlled and blinded protocols that satisfy the requirements of high-level evidence-based research. In most cases, the equipment and communications technology were not designed for individuals with upper extremity disability. It is clear that exercise therapy combined with interventions such as FES, supervised over the Internet, will soon be adopted worldwide in one form or another. Therefore it is timely that researchers, clinicians, and healthcare planners interested in assessing IHT be aware of the pros and cons of the new technology and the factors involved in designing appropriate studies of it. It is crucial to understand the technical barriers, the role of telesupervisors, the motor improvements that participants can reasonably expect and the process of optimizing IHT-exercise therapy protocols to maximize the benefits of the emerging technology.

    éano Atlántico y el comienzo de la depositación del Grupo Malargüe.The Neuquén Group conform a succession of non-marine deposits of fluvial, aeolian and shallow lacustrine origin, developed in the Neuquén Basin between the Lower Cenomanian and the Middle Campanian (Upper Cretaceous. This succession reaches 1,200 m of maximum thick, being bounded at the base and the top by the Patagonidican and Huantraiquican unconformities respectively. In this paper two new formations are proposed (Los Bastos and Sierra Barrosa Formations, nom. nov., and the subgroups were reconfigurated. Consequently, the Neuquén Group is composed lithostratigraphically by three subgroups and nine formations. The Río Limay Subgroup comprehend the Candeleros and Huincul Formations, representing low sinuosity channel deposits developed under tectonic and climatic subordinated control. The Río Neuquén Subgroup comprehend to the Cerro Lisandro, Portezuelo, Los Bastos, Sierra Barrosa and Plottier Formations, conforming a psamitic and pelitic interstratified succession of fluvial origin, mainly developed under climatic control. Finally, the Río Colorado Subgroup integrated by the Bajo de la Carpa and Anacleto Formations, comprehend fluvial deposits developed under a new dominant tectonic control. At the start of the deposition of the Neuquén Group, the Dorsal de Huincul worked as a structural high, generating toward the south of the Neuquén Basin one a small endorreic depocentre corresponding to the Picún Leufú Sub-basin, scheme that would have been keep up to ends of the deposit of the Candeleros Formation. During the rest of the deposit of this sequence, the drainage would have been kept without major modifications towards the pacific slope across a central collector flowing in sense N-NW. Towards the end of the deposit of the Neuquén Group takes place the inversion of the regional slope of the basin, making possible the ingression of the Atlantic Ocean and the beginning of the deposition of

    Full Text Available Objective: The occurrence of digestive complications especially upper gastrointestinal bleeding (UGIB has increased after cardiac surgery. The aim of this study was to determine the incidence of UGIB and identify the independent risk factors. Materials and Methods: We retrospectively analyzed data of 1077 patients undergoing cardiopulmonary bypass (CPB from 1994 to 2012 The group of patients with UGIB (n1 = 20 was compared with the population group (n2 = 1057. Demographic characteristics, therapeutic management, endoscopic findings, and outcomes were analyzed. Through a regression analysis we identified independent risk factors of UGIB. Results: The mean age of the group n1 was 58.2 ± 12.4 years and 50.18 ± 13.5 years in the group n2 . UGIB occurred about 13 ± 5.5 days after cardiac surgery. Gastroduodenal ulcer was the most common etiology of hemorrhage (n = 13, 65%. Renal insufficiency, previous gastric ulcer, increased lactate concentration during CPB, prolonged mechanical ventilation, use of vasopressor drug and pulmonary infection was likely contributing factors in UGIB. Conclusion: UGIB following open cardiac surgery is most frequently secondary to gastroduodenal ulceration. Many determinant factors of bleeding are incriminated. Surgeons must be aware of these factors to avoid fatal complications.

    Injuries stemming from shoulder instability are very common among athletes participating in contact sports, such as football. Previous research has shown that increased laxity negatively affects the function of the sensorimotor system potentially leading to a pathological cycle of shoulder dysfunction. Currently, there are no data detailing such effects among football players. Therefore, the purpose of this study was to examine the differences in upper extremity sensorimotor control among football players compared with that of a control group. Forty-five collegiate football players and 70 male control subjects with no previous experience in contact sports participated. All the subjects had no recent history of upper extremity injury. Each subject performed three 30-second upper extremity balance trials on each arm. The balance trials were conducted in a single-arm push-up position with the test arm in the center of a force platform and the subjects' feet on a labile device. The trials were averaged, and the differences in radial area deviation between groups were analyzed using separate 1-way analyses of variance (p football players showed significantly more radial area deviation of the dominant (0.41 ± 1.23 cm2, p = 0.02) and nondominant arms (0.47 ± 1.63 cm2, p = 0.03) when compared with the control group. These results suggest that football players may have decreased sensorimotor control of the upper extremity compared with individuals with no contact sport experience. The decreased upper extremity sensorimotor control among the football players may be because of the frequent impacts accumulated during football participation. Football players may benefit from exercises that target the sensorimotor system. These findings may also be beneficial in the evaluation and treatment of various upper extremity injuries among football players.

    Full Text Available En la ciudad de Neuquén y alrededores afloran depósitos del Cretácico superior asignados al Subgrupo Río Colorado. La presente contribución da a conocer los resultados del análisis sedimentológico y paleoambiental de las Formaciones Bajo de la Carpa (Santoniano y Anacleto (Campaniano inferior. Los estudios llevados a cabo permitieron definir cuatro litofacies conglomerádicas, nueve de areniscas y dos pelíticas, que fueron agrupadas en nueve asociaciones de litofacies, dos de ellas de origen eólico y siete fluviales. La Formación Bajo de la Carpa está representada en la base por un sistema fluvial efímero, y en el techo por depósitos de interacción fluvio- eólica. Los depósitos fluviales corresponden a flujos canalizados durante episodios de máxima descarga. Luego se identifica un campo de dunas transversales, afectado en el subambiente de interduna por corrientes fluviales efímeras, y dunas parabólicas producto de la removilización del sistema eólico infrayacente, asociadas con depósitos de flujos efímeros en manto. La extensión y geometría de los campos de dunas respondieron a variaciones climáticas de corto término, interferencia del sistema fluvial, oscilaciones del nivel freático, bajo suministro y/o disponibilidad de sedimentos y factores tectónicos. La Formación Anacleto presenta en su base sistemas fluviales de baja sinuosidad, alta energía y rápida agradación, controlados por un bajo espacio de acomodación y condiciones climáticas con marcada estacionalidad. Hacia el tope se identifica un sistema fluvial anastomosado que refleja variaciones climáticas y aumento de la tasa de subsidencia acompañada de un lento ascenso del nivel de base relacionado con la ingresión atlántica maastrichtiana.Upper Cretaceous deposits included in Río Colorado Subgroup crop out in Neuquén city and surrounding areas.

    [Purpose] This study investigated the therapeutic effects of virtual reality-based bilateral upper-extremity training on brain activity in patients with stroke. [Subjects and Methods] Eighteen chronic stroke patients were divided into two groups: the virtual reality-based bilateral upper-extremity training group (n = 10) and the bilateral upper-limb training group (n = 8). The virtual reality-based bilateral upper-extremity training group performed bilateral upper-extremity exercises in a virtual reality environment, while the bilateral upper-limb training group performed only bilateral upper-extremity exercise. All training was conducted 30 minutes per day, three times per week for six weeks, followed by brain activity evaluation. [Results] Electroencephalography showed significant increases in concentration in the frontopolar 2 and frontal 4 areas, and significant increases in brain activity in the frontopolar 1 and frontal 3 areas in the virtual reality-based bilateral upper-extremity training group. [Conclusion] Virtual reality-based bilateral upper-extremity training can improve the brain activity of stroke patients. Thus, virtual reality-based bilateral upper-extremity training is feasible and beneficial for improving brain activation in stroke patients.

  11. Cancer of the upper rectum.

    2016-10-01

    Rectal cancer constitutes one-third of all colorectal cancers, and the incidence in Denmark increasing. In 2012, 1.400 cases were registered, and of these 38% were located in the upper rectum. There have been several key advances in the optimal management of rectal cancer during the past decades, primarily by standardisation and improvement of the surgical procedure. There is now general agreement that the optimal surgical treatment involves the concept of total mesorectal excision and that a resection with tumour-free margins is crucial. Controversy exists as to whether total mesorectal excision (TME) is necessary for upper rectal cancers or if a partial mesorectal excision (PME) with mesorectal transection 5 cm below the tumour is adequate. Furthermore, there is no agreement as to whether surgery alone is sufficient or whether neoadjuvant radio- and/or chemotherapy should be administered for tumours of the upper rectum. This thesis aims to discuss aspects of the treatment of rectal cancer with regard to the adequacy of mesorectal excision and oncological outcome with a particular focus on cancer of the upper rectum. In study I, the extent and completeness of mesorectal excision was estimated by postoperative magnetic resonance imaging of the pelvis in patients with primary surgery for rectal cancer. In the 136 patients with post-operative MRI, inadvertent residual mesorectal tissue was evident in 40%, especially following PME, suggesting suboptimal surgery performed. Additionally in patients who had PME, the distal margin was found to be less than 3 cm in more than 50% of patients, suggesting a discrepancy between guidelines and the actual surgery performed. In study II, we estimated the risk of local recurrence in the previously audited cohort of patients, with a particular focus on patients with upper rectal cancer treated by PME and without neo-adjuvant therapy as standard. Using Kaplan-Meier analysis, the total three-year local recurrence rate was 7% with

Estos constituyen el tercio superior de la Formación Plottier y señalan una modificación abrupta en la evolución de los sistemas fluviales. La superficie erosiva y plana, seguida por cuerpos de areniscas tabulares y espesos, señala el período de caída en el nivel de base y estadio temprano de ascenso.A sedimentary succession was studied on the north margin of Los Barreales Lake, in northeastern of Neuquén, Argentina. These outcrops correspond to the Portezuelo and Plottier Formations, which are formally grouped as the Río Neuquén Subgroup of the Neuquén Group. The Plottier Formation is considered as upper Coniacian in age. In order to describe the distribution pattern and evolution of the paleoenvironments of this unit, eleven lithofacies were recognized and grouped into seven lithofacies associations that characterize different fluvial styles, which are named here as fluvial styles I, II and III. The fluvial style I is at the base of these outcrops and represents an ephemeral fluvial system characterized by isolate lenticular channels in flood plain deposits and frequent sheet floods events. Gradually, an increasing on the channel/floodplain relation is recorded. Channels becoming thicker and showing up a braided design, levees, crevasse splays and a strong multilateral relation are developed. These features are defining the fluvial style II. Large scale geometry of fluvial styles I and II are pointing out a progressive decrease on the accommodation/supply. Weather probably varied from sub-humid or semi-arid to humid climatic conditions with strong seasonal variations. These provoked important changes on the water and sediment discharge onto the fluvial system. At the middle part of Plottier Formation a 6° order discontinuity is defined. This is the border for a stacked channel

    2004-10-01

    During the past 20 years of NOAA operational polar satellites, it has become evident that a growing problem concerning their utilization in Climate and also Numerical Weather Prediction (NWP) applications are the systematic errors and uncertainties inherent in the satellite measurements. Similar arguments can be made for global radiosonde observations. These uncertainties are often larger than the sensitive signals and processes, that satellite and radiosonde measurements are designed to reveal, particularly in the realm of climate. Possible strategies to quantify and compensate for these problems include the analysis of satellite overlap data and/or available collocations of satellite and ground truth (radiosonde) observations. However, overlap observations are typically not available except in extreme polar regions and current sampling strategies for compiling collocated radiosonde and satellite observations are insufficient, further compounding the inherent uncertainties in the ground-truth radiosonde data. A Satellite Upper Air Network is proposed to provide reference radiosonde launches coincident with operational polar satellite(s) overpass. The SUAN consist of 36 global radiosonde stations sub-sampled from the Global Upper Air Network (GUAN), and is designed to provide a robust, global sample of collocated radiosonde and satellite observations conducive to the monitoring and validation of satellite and radiosonde observations. The routine operation of such a network in conjunction with operational polar satellites would provide a long-term of performance for critical observations of particular importance for climate. The following report presents a candidate network of 36 upper-air sites that could comprise a SUAN. Their selection along with the mutual benefit across the satellite, radiosonde, climate, numerical weather prediction (NWP) and radiative transfer (RT) model areas are discussed.

    Written by one of the subject’s foremost experts, this book focuses on the central developments and modern methods of the advanced theory of abelian groups, while remaining accessible, as an introduction and reference, to the non-specialist. It provides a coherent source for results scattered throughout the research literature with lots of new proofs. The presentation highlights major trends that have radically changed the modern character of the subject, in particular, the use of homological methods in the structure theory of various classes of abelian groups, and the use of advanced set-theoretical methods in the study of undecidability problems. The treatment of the latter trend includes Shelah’s seminal work on the undecidability in ZFC of Whitehead’s Problem; while the treatment of the former trend includes an extensive (but non-exhaustive) study of p-groups, torsion-free groups, mixed groups, and important classes of groups arising from ring theory. To prepare the reader to tackle these topics, th...

    Until recently, upper extremity prostheses had changed little since World War II. In 2006, the Defense Advanced Research Projects Agency responded to an increasing number of military amputees with the Revolutionizing Prosthetics program. The program has yielded several breakthroughs both in the engineering of new prosthetic arms and in the control of those arms. Direct brain-wave control of a limb with 22° of freedom may be within reach. In the meantime, advances such as individually powered digits have opened the door to multifunctional full and partial hand prostheses. Restoring sensation to the prosthetic limb remains a major challenge to full integration of the limb into a patient's self-image.

    The upper airway muscles play an important role in maintaining upper airway collapsibility, and the incidence of sleep-disordered breathing increases with age. We hypothesize that the increase in airway collapsibility with increasing age can be linked to changes in upper airway muscle mechanics and structure. Eight young (Y: 6 mo) and eight old (O: 30 mo) Fischer 344 rats were anesthetized and mechanically ventilated, and the pharyngeal pressure associated with flow limitation (Pcrit) was measured 1) with the hypoglossal (cnXII) nerve intact, 2) following bilateral cnXII denervation, and 3) during cnXII stimulation. With the cnXII intact, the upper airways of older rats were more collapsible compared with their younger counterparts [Pcrit = -7.1 +/- 0.6 (SE) vs. -9.5 +/- 0.7 cmH2O, respectively; P = 0.033]. CnXII denervation resulted in an increase in Pcrit such that Pcrit became similar in both groups (O: -4.2 +/- 0.5 cmH2O; Y: -5.4 +/- 0.5 cmH2O). In all rats, cnXII stimulation decreased Pcrit (less collapsible) in both groups (O: -11.3 +/- 1.0 cmH2O; Y: -10.2 +/- 1.0 cmH2O). The myosin heavy chain composition of the genioglossus muscle demonstrated a decrease in the percentage of the IIb isoform (38.3 +/- 2.5 vs. 21.7 +/- 1.7%; P collapsible with age and that the increase in upper airway collapsibility with age is likely related to altered neural control rather than to primary alterations in upper airway muscle structure and function.

    The Composites for Exploration Upper Stage (CEUS) was a 3-year, level III project within the Technology Demonstration Missions program of the NASA Space Technology Mission Directorate. Studies have shown that composites provide important programmatic enhancements, including reduced weight to increase capability and accelerated expansion of exploration and science mission objectives. The CEUS project was focused on technologies that best advanced innovation, infusion, and broad applications for the inclusion of composites on future large human-rated launch vehicles and spacecraft. The benefits included near- and far-term opportunities for infusion (NASA, industry/commercial, Department of Defense), demonstrated critical technologies and technically implementable evolvable innovations, and sustained Agency experience. The initial scope of the project was to advance technologies for large composite structures applicable to the Space Launch System (SLS) Exploration Upper Stage (EUS) by focusing on the affordability and technical performance of the EUS forward and aft skirts. The project was tasked to develop and demonstrate critical composite technologies with a focus on full-scale materials, design, manufacturing, and test using NASA in-house capabilities. This would have demonstrated a major advancement in confidence and matured the large-scale composite technology to a Technology Readiness Level 6. This project would, therefore, have bridged the gap for providing composite application to SLS upgrades, enabling future exploration missions.

    In recent years the amount of digital data in the world has risen immensely. But, the more information exists, the greater is the possibility of its unwanted disclosure. Thus, the data privacy protection has become a pressing problem of the present time. The task of individual privacy-preserving is being thoroughly studied nowadays. At the same time, the problem of statistical disclosure control for collective (or group) data is still open. In this paper we propose an effective and relatively simple (wavelet-based) way to provide group anonymity in collective data. We also provide a real-life example to illustrate the method.

    2015-06-01

    Full Text Available Upper Silesia in terms of ethnicity is a typical example of a historical region in Europe, but in fact, one of the few exceptions in contemporary Poland, where its mixed ethnic and religious structures have at least partly survived until today. While their existence had been denied by Nazi Germany (1933-1945 as well as by the Polish People's Republic (1945-1989, the emancipation of the German and Silesian minorities after the democratic changes of 1989 have evoked strong emotions in the ethnically almost uniform country. Nonetheless, the recent situation of minorities has improved as never before. Minority organisations has been officially recognized and German finally has become the second language in some municipalities of Upper Silesia, but the largest ethnic group in the whole country, the Silesians, have still experienced no formal recognition as a national minority. This article deals with the demographic aspects of the ethnic groups in Upper Silesia since the 19th century until recent times. The census results concerning the ethnic minorities or languages in Upper Silesia have been contested since the first records of that kind have been taken. The outcomes of the both last censuses of 2002 and 2011 concerning the minority question reflected for the first time a much more realistic picture of the status quo. Furthermore, they showed that the idea of Silesian identification found an unexpected high number of supporters. This fact indicates an emerging meaning of regional identification amid significant changes of cultural values in Polish society.

    It is well-known that work-related upper limb musculoskeletal disorders, particularly tendinitis and nerve entrapment, remain a difficult and costly problem in industrialized countries. The aim of this study was to evaluate tendinitis and entrapment neuropathy of the upper limb of Turkish coal miners. Eighty coal miners and 43 age-matched clerical workers were included in the study. The evaluation procedures included collection of personal and clinical data, physical examination and bilateral electrodiagnostic testing. Subjects were examined to diagnose tendinitis and nerve entrapment of the upper limb. Bilateral median and ulnar nerves conduction tests were performed on all subjects. Data were collected between August 2011 and December 2011. There were 33 subjects with lateral epicondylitis, 10 with medial epicondylitis, and 22 with De Quervain's disease among the coal miners. There were seven subjects with lateral epicondylitis, eight with medial epicondylitis, and four with De Quervain's disease in the control group. The two groups significantly differed in the prevalences of lateral epicondylitis and De Quervain's disease (P = 0.024 and P =0.029, respectively). Sixteen subjects in the coal miners and 12 subjects in the controls had carpal tunnel syndrome (P = 0.66). Thirty-seven subjects in the coal miners had ulnar neuropathy of the elbow (UNE), while four subjects in the controls had UNE; this difference was statistically significant (P Quervain disease, and ulnar neuropathy are common work-related upper limb disorders among coal miners.

    The purpose of this study was to evaluate the effects of mirror therapy program in addition with physical therapy methods on upper limb recovery in patients with subacute ischemic stroke. 15 subjects followed a comprehensive rehabilitative treatment, 8 subjects received only control therapy (CT) and 7 subjects received mirror therapy (MT) for 30 min every day, five times a week, for 6 weeks in addition to the conventional therapy. Brunnstrom stages, Fugl-Meyer Assessment (upper extremity), the Ashworth Scale, and Bhakta Test (finger flexion scale) were used to assess changes in upper limb motor recovery and motor function after intervention. After 6 weeks of treatment, patients in both groups showed significant improvements in the variables measured. Patients who received MT showed greater improvements compared to the CT group. The MT treatment results included: improvement of motor functions, manual skills and activities of daily living. The best results were obtained when the treatment was started soon after the stroke.

    The field of environmental toxicology has become quite important to the study of environmental health in human beings. The stability of the ecosystem in which we live is threatened by the nearly 5 million chemical compounds that have been synthesized worldwide, many of which have real or potentially toxic effects on the environment and on life forms. Four major groups of chemicals--metallic elements, nonmetallic elements, organic compounds and inorganic compounds--have certain agents within them that are known toxins to human beings. Some of these agents have an as yet unknown effect, whereas others have been well characterized. They can be found in the workplace, home, and outdoors, and many are unseen and odorless. In the past, most agents have been described in terms of their carcinogenic potential or major toxic effects on organ systems. It is now likely that the important characterization of some of these agents referrable to the upper aerodigestive tract should be at their receptor sites and identify the very discrete and small effects on these sites and their cumulative effects. The concept of threshold is probably an arbitrary one because to date these discrete effects have not been studied. Susceptibility on an individual basis probably varies from low to high, depending on the patient's immunologic and defense mechanisms and the existence of congenital or acquired risk factors. New attention must be given to more subtle effects on the upper aerodigestive tract (i.e., sinusitis and laryngitis) in view of the potential effects of certain toxic agents on these tissues.

    This study reviewed the clinical history and management of acquired growth arrest in the upper extremity in pediatric patients. The records of all patients presenting from 1996 to 2012 with radiographically proven acquired growth arrest were reviewed. Records were examined to determine the etiology and site of growth arrest, management, and complications. Patients with tumors or hereditary etiology were excluded. A total of 44 patients (24 boys and 20 girls) with 51 physeal arrests who presented at a mean age of 10.6 years (range, 0.8-18.2 years) were included in the study. The distal radius was the most common site (n=24), followed by the distal humerus (n=8), metacarpal (n=6), distal ulna (n=5), proximal humerus (n=4), radial head (n=3), and olecranon (n=1). Growth arrest was secondary to trauma (n=22), infection (n=11), idiopathy (n=6), inflammation (n=2), compartment syndrome (n=2), and avascular necrosis (n=1). Twenty-six patients (59%) underwent surgical intervention to address deformity caused by the physeal arrest. Operative procedures included ipsilateral unaffected bone epiphysiodesis (n=21), shortening osteotomy (n=10), lengthening osteotomy (n=8), excision of physeal bar or bone fragment (n=2), angular correction osteotomy (n=1), and creation of single bone forearm (n=1). Four complications occurred; 3 of these required additional procedures. Acquired upper extremity growth arrest usually is caused by trauma or infection, and the most frequent site is the distal radius. Growth disturbances due to premature arrest can be treated effectively with epiphysiodesis or osteotomy. In this series, the specific site of anatomic growth arrest was the primary factor in determining treatment. [Orthopedics. 2017; 40(1):e95-e103.]. Copyright 2016, SLACK Incorporated.

    For propulsion applications that require that the propellants are storable for long periods, have a high density impulse, and are environmentally clean and non-toxic, the best choice is a combination of high-concentration hydrogen peroxide (High Test Peroxide, or HTP) and a liquid hydrocarbon (LHC) fuel. The HTP/LHC combination is suitable for low-cost launch vehicles, space taxi and space maneuvering vehicles, and kick stages. Orbital Sciences Corporation is under contract with the NASA Marshall Space Flight Center in cooperation with the Air Force Research Lab to design, develop and demonstrate a new low-cost liquid upper stage based on HTP and JP-8. The Upper Stage Flight Experiment (USFE) focuses on key technologies necessary to demonstrate the operation of an inherently simple propulsion system with an innovative, state-of-the-art structure. Two key low-cost vehicle elements will be demonstrated - a 10,000 lbf thrust engine and an integrated composite tank structure. The suborbital flight test of the USFE is scheduled for 2001. Preceding the flight tests are two major series of ground tests at NASA Stennis Space Center and a subscale tank development program to identify compatible composite materials and to verify their compatibility over long periods of time. The ground tests include a thrust chamber development test series and an integrated stage test. This paper summarizes the results from the first phase of the thrust chamber development tests and the results to date from the tank material compatibility tests. Engine and tank configurations that meet the goals of the program are described.

    Randomized clinical trial. To compare the short-term effects of upper cervical and upper thoracic high-velocity low-amplitude (HVLA) thrust manipulation to nonthrust mobilization in patients with neck pain. Although upper cervical and upper thoracic HVLA thrust manipulation and nonthrust mobilization are common interventions for the management of neck pain, no studies have directly compared the effects of both upper cervical and upper thoracic HVLA thrust manipulation to nonthrust mobilization in patients with neck pain. Patients completed the Neck Disability Index, the numeric pain rating scale, the flexion-rotation test for measurement of C1-2 passive rotation range of motion, and the craniocervical flexion test for measurement of deep cervical flexor motor performance. Following the baseline evaluation, patients were randomized to receive either HVLA thrust manipulation or nonthrust mobilization to the upper cervical (C1-2) and upper thoracic (T1-2) spines. Patients were reexamined 48-hours after the initial examination and again completed the outcome measures. The effects of treatment on disability, pain, C1-2 passive rotation range of motion, and motor performance of the deep cervical flexors were examined with a 2-by-2 mixed-model analysis of variance (ANOVA). One hundred seven patients satisfied the eligibility criteria, agreed to participate, and were randomized into the HVLA thrust manipulation (n = 56) and nonthrust mobilization (n = 51) groups. The 2-by-2 ANOVA demonstrated that patients with mechanical neck pain who received the combination of upper cervical and upper thoracic HVLA thrust manipulation experienced significantly (Pthrust manipulation group had significantly (Pthrust manipulation is appreciably more effective in the short term than nonthrust mobilization in patients with mechanical neck pain.

  1. All finitely presentable groups from link complements and Kleinian groups

    CERN Document Server

    Aitchison, Iain R

    2010-01-01

    We prove that every finitely presentable group G arises as the fundamental group of an orientable 3-complex obtained from a hyperbolic link complement, by coning each boundary torus of the link exterior to a distinct point. We define the closed-link-genus, clg(G), of any finitely presentable group G, which completely characterizes fundamental groups of closed orientable 3-manifolds: clg(G)=0 if and only if G is the fundamental group of a closed orientable 3-manifold. Moreover clg(G) gives an upper bound for the concept `genus(G)' of genus defined earlier by Aitchison and Reeves, and in turn is bounded by the minimal number of relations among all finite presentations of G.

    2008-08-01

    This study aimed at demonstrating the asymmetry in volume between the dominant and nondominant upper limbs in tennis players, controlled for maturity status. Upper limb volumes on both sides were calculated in 72 tennis players and 84 control subjects, using the truncated cone method. The participants' maturity status was determined using the predicted age at peak height velocity (PHV). The results showed significant larger side-to-side asymmetry in volume in tennis groups than in control groups. These findings suggested that, even before PHV, specific-sport adaptations occurred in the dominant upper limb in tennis players.

    [Purpose] The purpose of this study was to conduct cervical stability training and upper thoracic manipulation for patients with chronic neck pain and then investigate the changes of cervical proprioception and pain. [Subjects and Methods] Subjects were 30 workers with mechanical neck pain, who were randomly divided into an upper thoracic manipulation group and a cervical stability training group. Upper thoracic manipulation after cervical stability training was conducted for the upper thoracic manipulation group, and only stability training was conducted for the cervical stability training group. The intervention period was six weeks, and consisted of three sessions a week, each of which lasted for 30 minutes. For proprioception measurement, an electro-goniometer was used to measure reposition sense before and after the intervention. The visual analogue scale was used to assess pain. [Results] After the intervention, the error angle was significantly smaller in flexion and right left side-bending, and pain was significantly reduced in the upper thoracic manipulation group. According to the post intervention comparison of the two groups, there were significant differences in the proprioception and pain values. [Conclusion] Conducting both cervical stability training and upper thoracic manipulation for patients with chronic neck pain was more helpful for the improvement of proprioception and pain than cervical stability training alone.

    Upper gastrointestinal (GI) bleeding is a condition requiring immediate medical intervention, with high associated mortality exceeding 10%. The most common cause of upper GI bleeding is peptic ulcer disease, which largely corresponds to the intake of NSAIDs and Helicobacter pylori infection. Endoscopy is the essential tool for the diagnosis and treatment of active upper GI hemorrhage. Endoscopic therapy together with proton pump inhibitors and eradication of Helicobacter pylori significantly reduces rebleeding rates, mortality and number of emergency surgical interventions. This paper presents contemporary data on the diagnosis and treatment of upper gastrointestinal bleeding.

    We report the case of a 53-year-old woman who presented with massive hemoptysis. Computed tomographic angiography revealed an anomalous vessel arising from the abdominal aorta, coursing anteriorly and through the diaphragm, and feeding the left upper lobe. At operation the vessel was found to anastomose to the left upper lobe lingula, which contained multiple vascular abnormalities and arteriovenous fistulas. The vessel was ligated, and the affected portion of the left upper lobe was resected. Anomalous systemic arterial supply of an upper lobe is an especially rare form of a Pryce type 1 abnormality. Recognition of these unusual anatomic variants is crucial to successful treatment and avoidance of adverse events.

  12. Smartphone supported upper limb prosthesis

    2015-09-01

    Full Text Available State of the art upper limb prostheses offer up to six active DoFs (degrees of freedom and are controlled using different grip patterns. This low number of DoFs combined with a machine-human-interface which does not provide control over all DoFs separately result in a lack of usability for the patient. The aim of this novel upper limb prosthesis is both offering simplified control possibilities for changing grip patterns depending on the patients’ priorities and the improvement of grasp capability. Design development followed the design process requirements given by the European Medical Device Directive 93/42 ECC and was structured into the topics mechanics, software and drive technology. First user needs were identified by literature research and by patient feedback. Consequently, concepts were evaluated against technical and usability requirements. A first evaluation prototype with one active DoF per finger was manufactured. In a second step a test setup with two active DoF per finger was designed. The prototype is connected to an Android based smartphone application. Two main grip patterns can be preselected in the software application and afterwards changed and used by the EMG signal. Three different control algorithms can be selected: “all-day”, “fine” and “tired muscle”. Further parameters can be adjusted to customize the prosthesis to the patients’ needs. First patient feedback certified the prosthesis an improved level of handling compared to the existing devices. Using the two DoF test setup, the possibilities of finger control with a neural network are evaluated at the moment. In a first user feedback test, the smartphone based software application increased the device usability, e.g. the change within preselected grip patterns and the “tired muscle” algorithm. Although the overall software application was positively rated, the handling of the prosthesis itself needs to be proven within a patient study to be

    The identification of intrinsic factors for predicting upper extremity motor outcome could aid the design of individualized treatment plans in stroke rehabilitation. The aim of this study was to identify prognostic factors, including intrinsic genetic factors, for upper extremity motor outcome in patients with subacute stroke. A total of 97 patients with subacute stroke were enrolled. Upper limb motor impairment was scored according to the upper limb of Fugl-Meyer assessment score at 3 months after stroke. The prediction of upper extremity motor outcome at 3 months was modeled using various factors that could potentially influence this impairment, including patient characteristics, baseline upper extremity motor impairment, functional and structural integrity of the corticospinal tract, and brain-derived neurotrophic factor genotype. Multivariate ordinal logistic regression models were used to identify the significance of each factor. The independent predictors of motor outcome at 3 months were baseline upper extremity motor impairment, age, stroke type, and corticospinal tract functional integrity in all stroke patients. However, in the group with severe motor impairment at baseline (upper limb score of Fugl-Meyer assessment stroke. Brain-derived neurotrophic factor genotype may be a potentially useful predictor of upper extremity motor outcome in patients with subacute stroke with severe baseline motor involvement. © 2017 American Heart Association, Inc.

    Patients with CKD receiving maintenance dialysis are at risk for upper gastrointestinal bleeding. However, the risk of upper gastrointestinal bleeding in patients with early CKD who are not receiving dialysis is unknown. The hypothesis was that their risk of upper gastrointestinal bleeding is negatively linked to renal function. To test this hypothesis, the association between eGFR and risk of upper gastrointestinal bleeding in patients with stages 3-5 CKD who were not receiving dialysis was analyzed. Patients with stages 3-5 CKD in the CKD program from 2003 to 2009 were enrolled and prospectively followed until December of 2012 to monitor the development of upper gastrointestinal bleeding. The risk of upper gastrointestinal bleeding was analyzed using competing-risks regression with time-varying covariates. In total, 2968 patients with stages 3-5 CKD who were not receiving dialysis were followed for a median of 1.9 years. The incidence of upper gastrointestinal bleeding per 100 patient-years was 3.7 (95% confidence interval, 3.5 to 3.9) in patients with stage 3 CKD, 5.0 (95% confidence interval, 4.8 to 5.3) in patients with stage 4 CKD, and 13.9 (95% confidence interval, 13.1 to 14.8) in patients with stage 5 CKD. Higher eGFR was associated with a lower risk of upper gastrointestinal bleeding (P=0.03), with a subdistribution hazard ratio of 0.93 (95% confidence interval, 0.87 to 0.99) for every 5 ml/min per 1.73 m(2) higher eGFR.

    Waterman, Jason J; Kapur, Rahul

    2012-01-01

    Gastrointestinal (GI) complaints are common among athletes with rates in the range of 30% to 70%. Both the intensity of sport and the type of sporting activity have been shown to be contributing factors in the development of GI symptoms. Three important factors have been postulated as contributing to the pathophysiology of GI complaints in athletes: mechanical forces, altered GI blood flow, and neuroendocrine changes. As a result of those factors, gastroesophageal reflux disease (GERD), nausea, vomiting, gastritis, peptic ulcers, GI bleeding, or exercise-related transient abdominal pain (ETAP) may develop. GERD may be treated with changes in eating habits, lifestyle modifications, and training modifications. Nausea and vomiting may respond to simple training modifications, including no solid food 3 hours prior to an athletic event. Mechanical trauma, decreased splanchnic blood flow during exercise, and non-steroidal anti-inflammatory drugs (NSAID) contribute to gastritis, GI bleeding, and ulcer formation in athletes. Acid suppression with proton-pump inhibitors may be useful in athletes with persistence of any of the above symptoms. ETAP is a common, poorly-understood, self-limited acute abdominal pain which is difficult to treat. ETAP incidence increases in athletes beginning a new exercise program or increasing the intensity of their current exercise program. ETAP may respond to changes in breathing patterns or may resolve simply with continued training. Evaluation of the athlete with upper GI symptoms requires a thorough history, a detailed training log, a focused physical examination aimed at ruling out potentially serious causes of symptoms, and follow-up laboratory testing based on concerning physical examination findings.

    Full Text Available This paper presents a revised lithostratigraphic scheme for the uppermost Upper Oligocene – Miocene succession of Denmark. The marine Oligocene Brejning Clay Member is upgraded to formation status and includes the Sydklint Member and the Øksenrade Member (new. The shallow marine and deltaic deposits of mainly Early Miocene age are included in the Ribe Group (new while the fully marine Middle and Upper Miocene clay-rich deposits are referred to the Måde Group (new. The Ribe Group is subdivided into 6 formations: the Vejle Fjord Formation is revised and includes the Skansebakke Member,the Billund Formation (new includes the Addit and Hvidbjerg Members (new, the Klintinghoved Formation is redefined formally and includes the Koldingfjord Member (new, the Bastrup Formation(new includes the Resen Member (new, the Vandel Member is a new member in the Arnum Formation (revised, the Odderup Formation is redefined and includes the Stauning Member (new and the coalbearing Fasterholt Member. The Måde Group is subdivided into the Hodde, Ørnhøj (new, Gram and Marbæk (new Formations. Subdivision of the Upper Oligocene – Miocene succession into two groups, the Ribe and Måde Groups, is compatible with the North Sea lithostratigraphic framework where they correlate with the upper part of the Hordaland Group and the Nordland Group, respectively. The revised lithostratigraphic framework correlated in three dimensions provides rigorous constraints on the palaeogeographic interpretation of the Late Oligocene – Miocene period. Three major deltaic units (Billund, Bastrup and Odderup Formations prograded from the north and north-east into the North Sea Basin during the Early – early Middle Miocene. Delta progradation was punctuated by deposition of marine clay and silt associated with minor transgressive events (Vejle Fjord, Klintinghoved and Arnum Formations. During the Middle–Late Miocene, marine depositional conditions dominated (Hodde, Ørnhøj and

    Stone, Jayme M.; Hanson, Jenny L.; Sattler, Stephanie R.

    2017-03-23

    The Upper Mississippi River System (UMRS), the navigable part of the Upper Mississippi and Illinois Rivers, is a diverse ecosystem that contains river channels, tributaries, shallow-water wetlands, backwater lakes, and flood-plain forests. Approximately 10,000 years of geologic and hydrographic history exist within the UMRS. Because it maintains crucial wildlife and fish habitats, the dynamic ecosystems of the Upper Mississippi River Basin and its tributaries are contingent on the adjacent flood plains and water-level fluctuations of the Mississippi River. Separate data for flood-plain elevation (lidar) and riverbed elevation (bathymetry) were collected on the UMRS by the U.S. Army Corps of Engineers’ (USACE) Upper Mississippi River Restoration (UMRR) Program. Using the two elevation datasets, the U.S. Geological Survey (USGS) Upper Midwest Environmental Sciences Center (UMESC) developed a systemic topobathy dataset.

    For a self-similar set E satisfying the open set condition,upper convex density is an important concept for the computation of its Hausdorff measure,and it is well known that the set of relative interior points with upper convex density 1has a full Hausdorff measure.But whether the upper convex densities of E at all the relative interior points are equal to 1? In other words,whether there exists a relative interior point of E such that the upper convex density of E at this point is less than 1?In this paper,the authors construct a self-similar set satisfying the open set condition,which has a relative interior point with upper convex density less than 1.Thereby,the above problem is sufficiently answered.

  8. Effect of Upper Extremity Robot-Assisted Exercise on Spasticity in Stroke Patients

    Science.gov (United States)

    2016-01-01

    Objective To determine the efficacy of a stretching and strengthening exercise program using an upper extremity robot, as compared with a conventional occupational therapy program for upper extremity spasticity in stroke patients. Methods Subjects were randomly divided into a robot-assisted therapy (RT) group and a conventional rehabilitation therapy (CT) group. RT group patients received RT and CT once daily for 30 minutes each, 5 days a week, for 2 weeks. RT was performed using an upper-extremity robot (Neuro-X; Apsun Inc., Seoul, Korea), and CT was administered by occupational therapists. CT group patients received CT alone twice daily for 30 minutes, 5 days a week, for 2 weeks. Modified Ashworth Scale (MAS) was used to measure the spasticity of upper extremity. Manual muscle tests (MMT), Manual Function Tests (MFT), Brunnstrom stage, and the Korean version of Modified Barthel Index (K-MBI) were used to measure the strength and function of upper extremity. All measurements were obtained before and after 2-week treatment. Results The RT and CT groups included 22 subjects each. After treatment, both groups showed significantly lower MAS scores and significant improvement in the MMT, MFT, Brunnstrom stage, and K-MBI scores. Treatment effects showed no significant differences between the two groups. Conclusion RT showed similar treatment benefits on spasticity, as compared to CT. The study results suggested that RT could be a useful method for continuous, repeatable, and relatively accurate range of motion exercise in stroke patients with spasticity. PMID:28119825

    The aim of this study was to compare the flexibility of the upper extremities in collegiate students involved in Aikido (a kind of soft martial art attracting youth) training with those involved in other sports. Fifty freshmen with a similar frequency of exercise were divided into the Aikido group (n = 18), the upper-body sports group (n = 17), and the lower-body sports group (n = 15) according to the sports that they participated in. Eight classes of range of motion in upper extremities were taken for all subjects by the same clinicians. The Aikido group had significantly better flexibility than the upper-body sports group except for range of motion in shoulder flexion (p = 0.22), shoulder lateral rotation (p > 0.99), and wrist extension (p > 0.99). The Aikido group also had significantly better flexibility than the lower-body sports group (p martial arts had good upper extremities flexibility that might not result from regular exercise alone.

  10. EFFECT OF MIRROR THERAPY ON HEMIPARETIC UPPER EXTREMITY IN SUBACUTE STROKE PATIENTS

    2015-12-01

    Full Text Available Background: Stroke is one of the most common causes for chronic disability. Only 5 to 20% of stroke survivors attain complete functional recovery of their affected upper extremity. The primary objective of this study was to investigate the effect of mirror therapy on hemiparetic upper extremity motor recovery and functions in patients with subacute stroke. Methods: A total of 30 participants were selected for the study. They were randomly assigned to Mirror Therapy Group (MTG and Sham Mirror Therapy Group (SMTG with fifteen participants in each group. All the participants equally took part in conventional stroke rehabilitation program 5 days a week for 4 weeks. In addition to the conventional stroke rehabilitation program, MTG participated in 30 minutes of mirror therapy and SMTG received 30 minutes of sham mirror therapy for the affected hemiparetic upper limb. The participants were measured for upper extremity motor recovery and functions by Fugl-Meyer Assessment (FMA-UE and Upper Extremity Functional Index (UEFI scales respectively. Results: Wilcoxon signed ranks test and Mann Whitney U test were used to statistically analyze the data. Spearman correlational technique was used to analyze the relationship between upper limb functions and motor recovery of hand. Based on Wilcoxon signed ranks test, the results were highly significant (p<0.05. On the basis of Mann Whitney U test, Mirror therapy group showed high significance (p<0.05 than sham mirror therapy group. The Spearman’s rho value was 0.65 which indicated moderate to maximum positive correlation between the two variables and the alpha level was set at 0.01. Conclusion: This study concludes that incorporating mirror therapy in subacute stroke rehabilitation program improves the hemiparetic upper extremity motor recovery and its functions and also motor recovery of hand can directly influence the upper limb functions.

    2012-11-01

    Upper respiratory tract infections account for millions of visits to family physicians each year in the United States. Although warranted in some cases, antibiotics are greatly overused. This article outlines the guidelines and indications for appropriate antibiotic use for common upper respiratory infections. Early antibiotic treatment may be indicated in patients with acute otitis media, group A beta-hemolytic streptococcal pharyngitis, epiglottitis, or bronchitis caused by pertussis. Persistent cases of rhinosinusitis may necessitate the use of antibiotics if symptoms persist beyond a period of observation. Antibiotics should not be considered in patients with the common cold or laryngitis. Judicious, evidence-based use of antibiotics will help contain costs and prevent adverse effects and drug resistance.

    Science.gov (United States)

    2014-01-01

    The existing shortage of therapists and caregivers assisting physically disabled individuals at home is expected to increase and become serious problem in the near future. The patient population needing physical rehabilitation of the upper extremity is also constantly increasing. Robotic devices have the potential to address this problem as noted by the results of recent research studies. However, the availability of these devices in clinical settings is limited, leaving plenty of room for improvement. The purpose of this paper is to document a review of robotic devices for upper limb rehabilitation including those in developing phase in order to provide a comprehensive reference about existing solutions and facilitate the development of new and improved devices. In particular the following issues are discussed: application field, target group, type of assistance, mechanical design, control strategy and clinical evaluation. This paper also includes a comprehensive, tabulated comparison of technical solutions implemented in various systems. PMID:24401110

  13. Gallstone ileus as a cause of upper intestinal obstruction

    Directory of Open Access Journals (Sweden)

    Israel Szajnbock

    Full Text Available Gallstone ileus, a mechanical intestinal obstruction caused by the passage of a gallstone into the intestinal lumen through a fistula, although not common, deserves to more carefully studied due to its morbidity and mortality. Its incidence among older-age groups explains its association with chronic and degenerative diseases, which increase the complexity of the treatment choice.The need and appropriateness of a surgical approach to a cholecystenteric fistula to solve the obstructive emergency, in a one or two stage procedure, has been discussed in the literature. It has also been reported that gallstone ileus is an uncommon cause of upper intestinal obstruction. Intestinal obstruction is seen more frequently after a gallstone impacts at the ileocecal valve. The authors report a case of gallstone ileus as a cause of upper intestinal obstruction and discuss its diagnosis and treatment.

  14. Evolutionary trends of stature in upper Paleolithic and Mesolithic Europe.

    1999-03-01

    Long bone lengths of all available European Upper Paleolithic (41 males, 25 females) and Mesolithic (171 males, 118 females) remains have been transformed into stature estimates by means of new regression equations derived from Early Holocene skeletal samples using "Fully's anatomical stature" and the major axis regression technique (Formicola & Franceschi, 1996). Statistical analysis of the data, with reference both to time and space parameters, indicates that: (1) Early Upper Paleolithic samples (pre-Glacial Maximum) are very tall; (2) Late Upper Paleolithic groups (post-Glacial Maximum) from Western Europe, compared to their ancestors, show a marked decrease in height; (3) a further, although not significant, reduction of stature affects Western Mesolithics; (4) no regional differences have been observed during both phases of the Upper Paleolithic; (5) a high level of homogeneity has also been found in the Mesolithic, both in Western and Eastern Europe; (6) the internal homogeneity found during the Mesolithic in Western and Eastern Europe is associated with marked inter-regional variability, with populations of the latter region showing systematically significantly greater stature than their Western contemporaries. Evaluation of possible causes for the great stature of the Early Upper Paleolithic samples points to high nutritional standards as the most important factor. Results obtained on later groups clearly indicate that the Last Glacial Maximum, rather than the Mesolithic transition, is the critical phase in the negative trend affecting Western European populations. While changes in the quality of the diet, and in particular decreased protein intake, provide a likely explanation for that trend, variations in levels of gene flow probably also played a role. Reasons for the West-East Mesolithic dichotomy remain unclear and lack of information for the Late Upper Paleolithic of Eastern Europe prevents insight into the remote origins of this phenomenon.

    2012-01-01

    Background Emergency endoscopy for every patient with upper gastrointestinal hemorrhage is not possible in many medical centers. Simple guidelines to select patients for emergency endoscopy are lacking. The aim of the present report is to develop a simple scoring system to classify upper gastrointestinal hemorrhage (UGIH) severity based on patient clinical profiles at the emergency departments. Methods Retrospective data of patients with UGIH in a university affiliated hospital were analyzed. Patients were criterion-classified into 3 severity levels: mild, moderate and severe. Clinical and laboratory information were compared among the 3 groups. Significant parameters were selected as indicators of severity. Coefficients of significant multivariable parameters were transformed into item scores, which added up as individual severity scores. The scores were used to classify patients into 3 urgency levels: non-urgent, urgent and emergent groups. Score-classification and criterion-classification were compared. Results Significant parameters in the model were age ≥ 60 years, pulse rate ≥ 100/min, systolic blood pressure 16, n = 121, 11.9%). The score correctly classified 81.4% of the patients into their original (criterion-classified) severity groups. Under-estimation (7.5%) and over-estimation (11.1%) were clinically acceptable. Conclusions Our UGIH severity scoring system classified patients into 3 urgency groups: non-urgent, urgent and emergent, with clinically acceptable small number of under- and over-estimations. Its discriminative ability and precision should be validated before adopting into clinical practice. PMID:27785211

  2. Saline Nasal Irrigation for Upper Respiratory Conditions

    Science.gov (United States)

    2009-01-01

    Acute and chronic upper respiratory conditions are common and expensive disorders with enormous impact on patient quality of life and society at large. Saline nasal irrigation (SNI), a therapy with roots in Ayurvedic medicine that bathes the nasal mucosa with in spray or liquid saline, has been used as adjunctive care for upper respiratory conditions. In liquid form, SNI has been found to be effective adjunctive care by the Cochrane Collaboration for symptoms associated with chronic rhinosinusitis. Less conclusive clinical trial evidence supports its use in spray and liquid forms as adjunctive treatment for mild-to-moderate allergic rhinitis and acute upper respiratory infections. Consensus or expert opinion recommendations exist for SNI as a treatment for a variety of other conditions including rhinitis of pregnancy. SNI appears safe; side effects are minimal and transient. It can be recommended by clinicians to interested patients with a range of upper respiratory conditions in the context of patient education and printed instructional handouts. PMID:19904896

    1994-04-01

    The article deals with the use of different types of upper limb prostheses in Slovenia. Four hundred and fourteen upper limb amputees were sent a questionnaire on the type of their prosthesis, its use and reasons for non-use, respectively. The replies were subject to statistical analysis. Most of the questioned upper limb amputees (70%) wear a prosthesis only for cosmesis. The use of a prosthesis depends on the level of upper limb amputation, loss of the dominant hand, and time from amputation. Prosthetic success appears to be unrelated to age at the time of amputation and the rehabilitation programme. The most frequent reason for not wearing a prosthesis is heat and consequent sweating of the stump. More than a third of amputees are dissatisfied with their prostheses.

    A meta-analysis comparing outcomes of upper lobectomies with or without pleural tenting was performed. Five trials comprising 396 patients were selected. There was significantly reduced duration of hospital stay, chest drain use, and air leak in the pleural tenting group compared with the group without the pleural tent. There was also a significant reduction in number of patients with prolonged air leak more than 7 days in pleural tenting group. No other difference was noted in other outcomes such as total drainage, operative time, or hospital costs. In patients at high-risk of air leak, we advocate concomitant use of the pleural tent after upper lobectomies.

    We introduce a definition of upper Lyapunov exponent for quantum systems in the Heisenberg representation, and apply it to parametric quantum oscillators. We provide a simple proof that the upper quantum Lyapunov exponent ranges from zero to a positive value, as the parameters range from the classical system's region of stability to the instability region. It is also proved that in the instability region the parametric quantum oscillator satisfies the discrete quantum Anosov relations defined by Emch, Narnhofer, Sewell, and Thirring.

    Since 1989 amputees with upper-extremity burns have been fitted with a temporary prosthesis fabricated from low-temperature thermoplastic. Before 1989 conventional temporary prostheses were fabricated with plaster. The use of the thermoplastic material has produced a lightweight, cost-effective, modular system. No patients exhibited skin breakdown with the thermoplastic material. It appears that thermoplastics may be the next major breakthrough in terms of a design for a temporary upper-extremity prosthesis.

Though effective pharmacotherapy options exist, no agent is universally efficacious; therapeutic decisions must account for individual patient preferences. Oral H1-antihistamines, though effective for the common symptoms of allergic rhinitis, have modest decongestant action, as do leukotriene receptor antagonists. Intranasal antihistamines appear to improve congestion better than oral forms. Topical decongestants reduce congestion associated with allergic rhinitis, but local adverse effects make them unsuitable for long-term use. Oral decongestants show some efficacy against congestion in allergic rhinitis and the common cold, and can be combined with oral antihistamines. Intranasal corticosteroids have broad anti-inflammatory activities, are the most potent long-term pharmacologic treatment of congestion associated with allergic rhinitis, and show some congestion relief in rhinosinusitis and nasal polyposis. Immunotherapy and surgery may be used in some cases refractory to pharmacotherapy. Steps in congestion management include (1 diagnosis of the cause(s, (2 patient education and monitoring, (3 avoidance of environmental triggers where possible, (4 pharmacotherapy, and (5 immunotherapy

    Full Text Available Purpose : To study the association of various risk factors and epidemiological variables of mycotic keratitis treated at a tertiary referral hospital of upper Assam. Materials and Methods: In this hospital-based prospective study a total of 310 consecutive corneal ulcer cases attending the ophthalmology outpatient department of Assam Medical College were enrolled between April 2007 and March 2009. After clinical and slit-lamp biomicroscopic examination in all suspected cases, smears and culture examination for fungus was done to establish the etiology. Demographic information and associated probable risk factors of individual cases were noted in a predesigned questionnaire. Results: In 188 (60.6% cases fungal etiology could be established. Out of them 67.6% were males. The most commonly affected age group was 41-50 years (25.5%. The maximum (23.4% cases were reported during the paddy harvesting season in Assam (January and February. Fungal element could be demonstrated in 65.2% cases in direct potassium hydroxide (KOH mount. The commonest predisposing factor was corneal injury (74.5%. While diabetes was a significant systemic predisposing factor in mixed bacterial and fungal infections in 11.1% cases, blocked naso-lacrimal duct was the local predisposing factor in 11.1% of cases. Fusarium solani (25% was the commonest isolate followed by Aspergillus species (19%, Curvularia species (18.5% and Penicillium species (15.2%. Yeasts were isolated in 2.7% (n=5 cases. Conclusions : Ocular trauma was the commonest cause of fungal corneal ulcer in Assam and Fusarium solani was the commonest species responsible for it. Most of the mycotic ulcer cases come from rural areas including the tea gardens.

    Background Tranexamic acid reduces haemorrhage through its antifibrinolytic effects. In a previous version of the present review, we found that tranexamic acid may reduce mortality. This review includes updated searches and new trials.Objectives To assess the effects of tranexamic acid versus no intervention, placebo or other antiulcer drugs for upper gastrointestinal bleeding.Search methods We updated the review by performing electronic database searches (Cochrane Central Register of Controlled Trials (CENTRAL),MEDLINE, EMBASE, Science Citation Index) and manual searches in July 2014.Selection criteriaRandomised controlled trials, irrespective of language or publication status.Data collection and analysis We used the standard methodological procedures of the The Cochrane Collaboration. All-cause mortality, bleeding and adverse events were the primary outcome measures. We performed fixed-effect and random-effects model meta-analyses and presented results as risk ratios (RRs) with 95% confidence intervals (CIs) and used I² as a measure of between-trial heterogeneity. We analysed tranexamic acid versus placebo or no intervention and tranexamic acid versus antiulcer drugs separately. To analyse sources of heterogeneity and robustness of the overall results, we performed subgroup, sensitivity and sequential analyses.Main results We included eight randomised controlled trials on tranexamic acid for upper gastrointestinal bleeding. Additionally, we identified one large ongoing pragmatic randomised controlled trial from which data are not yet available. Control groups were randomly assigned to placebo (seven trials) or no intervention (one trial). Two trials also included a control group randomly assigned to antiulcer drugs(lansoprazole or cimetidine). The included studies were published from 1973 to 2011. The number of participants randomly assigned ranged from 47 to 216 (median 204). All trials reported mortality. In total, 42 of 851 participants randomly assigned to

    Endoscopic hemostasis is widely performed for nonvariceal upper gastrointestinal (UGI) bleeding. As the aged Japanese population rapidly increases, the number of patients experiencing complications increases. The aim of this study was to evaluate the recent results of endoscopic hemostasis for nonvariceal UGI bleeding. A retrospective analysis of patients who underwent endoscopic procedures for nonvariceal UGI bleeding was performed. We performed 223 endoscopic procedures on 217 patients between January 1995 and July 2000, and 238 endoscopic procedures on 236 patients between January 2006 and September 2009 at the Kyoto Second Red Cross Hospital. We divided the patients into the 1995-2000 group and the 2006-2009 group. Patient characteristics, hemostasis methods chosen, rates of temporary hemostasis and rebleeding, and mortality were analyzed. There were many serious and actively bleeding cases in the 2006-2009 group (P < 0.001). The endoclip method and intravenous proton pump inhibitor were mainly used in the 2006-2009 group compared with the drug-injection method and intravenous H2 receptor antagonist in the 1995-2000 group (P < 0.001). Through these treatments, the two groups were able to obtain similar treatment outcomes. Through the progress of endoscopic management we obtained similar satisfactory results in the 2006-2009 group, which had multiple complicated cases, compared to the 1995-2000 group.

    Respiratory consequences from occupational and environmental disasters are the result of inhalation exposures to chemicals, particulate matter (dusts and fibers) and/or the incomplete products of combustion that are often liberated during disasters such as fires, building collapses, explosions and volcanoes. Unfortunately, experience has shown that environmental controls and effective respiratory protection are often unavailable during the first days to week after a large-scale disaster. The English literature was reviewed using the key words-disaster and any of the following: respiratory disease, pulmonary, asthma, bronchitis, sinusitis, pulmonary fibrosis, or sarcoidosis. Respiratory health consequences after aerosolized exposures to high-concentrations of particulates and chemicals can be grouped into 4 major categories: 1) upper respiratory disease (chronic rhinosinusitis and reactive upper airways dysfunction syndrome), 2) lower respiratory diseases (reactive [lower] airways dysfunction syndrome, irritant-induced asthma, and chronic obstructive airways diseases), 3) parenchymal or interstitial lung diseases (sarcoidosis, pulmonary fibrosis, and bronchiolitis obliterans, and 4) cancers of the lung and pleura. This review describes several respiratory consequences of occupational and environmental disasters and uses the World Trade Center disaster to illustrate in detail the consequences of chronic upper and lower respiratory inflammation.

    @@Throughout, R is a Jacobson radical ring, and define a°b = a + b - ab and [a,b] = ab - ba for any a, b∈R. Then (R,°) is a group with identity 0, called the adjoint or circle group of R, and (R, + ,[,]) is a Lie ring, called the associated Lie ring of R. It was proved by Jennings[1] that (R,°) is a nilpotent group if and only if (R, +,[,]) is a nilpotent Lie ring, and he conjectured that their nilpotency classes are the same. Laue[2] partially verified Jennings' conjecture and his results gave rise to the conjecture that Zn = Yn for any non-negative integer n, where Zn and Yn are the nth terms of the upper central chains of (R, +,[,]) and (R,°), respectively.

    Upper endoscopy is an invasive procedure. However, the benefits of routinely administered sedative medication or topical pharyngeal anesthesic are controversial. The aim of this study was to clarify their effects on patient tolerance and difficulty of upper endoscopy. A total of 252 patients scheduled for diagnostic upper endoscopy were randomly assigned to 4 groups: (1) sedation with midazolam and placebo pharyngeal spray (midazolam group), (2) placebo sedation and lidocaine pharyngeal spray (lidocaine group), (3) placebo sedation and placebo pharyngeal spray (placebo group), and (4) no intravenous cannula/pharyngeal spray (control group). The endoscopist and the patient assessed the procedure immediately after the examination. Another questionnaire was sent to the patients 2 weeks later. Patients in the midazolam group rated the examination easier and less uncomfortable compared with those in the other groups. The differences were especially evident in the questionnaires completed 2 weeks after the examination ( p < 0.001). Lidocaine did not significantly improve patient tolerance. However, endoscopists found the procedure easier in patients in the lidocaine group compared with the midazolam ( p < 0.01) and control groups ( p < 0.01) but not the placebo group. Routine administration of midazolam for sedation increased patient tolerance for upper endoscopy. However, endoscopists found intubation to be more difficult in sedated vs. non-sedated patients. Topical pharyngeal anesthesia did not enhance patient tolerance, but it did make upper endoscopy technically easier compared with endoscopy in patients sedated with midazolam without topical pharyngeal anesthesia, and in patients who had no sedation or pharyngeal anesthesia, but not in patients who received placebo sedation and placebo pharyngeal anesthesia.

  9. Citronelle Dome: A giant opportunity for multizone carbon storage and enhanced oil recovery in the Mississippi Interior Salt Basin of Alabama

    The Citronelle Dome is a giant, salt-cored anticline in the eastern Mississippi Interior Salt Basin of southern Alabama that is located near several large-scale, stationary, carbon-emitting sources in the greater Mobile area. The dome forms an elliptical, four-way structural closure containing opportunities for CO2-enhanced oil recovery (CO2-EOR) and large-capacity saline reservoir CO2 sequestration. The Citronelle oil field, located on the crest of the dome, has produced more than 169 million bbl of 42-46?? API gravity oil from sandstone bodies in the Lower Cretaceous Rodessa Formation. The top seal for the oil accumulation is a thick succession of shale and anhydrite, and the reservoir is underfilled such that oil-water contacts are typically elevated 30-60 m (100-200 ft) above the structural spill point. Approximately 31-34% of the original oil in place has been recovered by primary and secondary methods, and CO2-EOR has the potential to increase reserves by up to 20%. Structural contour maps of the dome demonstrate that the area of structural closure increases upward in section. Sandstone units providing prospective carbon sinks include the Massive and Pilot sands of the lower Tuscaloosa Group, as well as several sandstone units in the upper Tuscaloosa Group and the Eutaw Formation. Many of these sandstone units are characterized by high porosity and permeability with low heterogeneity. The Tuscaloosa-Eutaw interval is capped by up to 610 m (2000 ft) of chalk and marine shale that are proven reservoir seals in nearby oil fields. Therefore, the Citronelle Dome can be considered a major geologic sink where CO2 can be safely stored while realizing the economic benefits associated with CO2-EOR. Copyright ?? 2008.

    The authors discuss problems and techniques of rehabilitation in subjects who have undergone upper limb amputation, as well as the requirements for good application of a prosthesis. Various types of prostheses are described: passive ones, those moved by the body and externally operated ones. The amputee undergoes three stages of rehabilitation: a general preparatory phase for maintenance of good joint function and muscle efficiency; a phase of specific rehabilitation with the help of electromyometry and an electronic training device for the use of the prosthesis, and finally individual and group exercises in laboratories with special facilities.

    Upper tract nephrolithiasis is a common surgical condition that is treated with multiple surgical techniques, including shock wave lithotripsy, ureteroscopy and percutaneous nephrolithotomy. We analyzed case logs submitted to the ABU by candidates for initial certification and recertification to help elucidate the trends in management of upper tract urinary calculi. Annualized case logs from 2003 to 2012 were analyzed. We used logistic regression models to assess how surgeon specific attributes affected the way that upper tract stones were treated. Cases were identified by the CPT code of the corresponding procedure. A total of 6,620 urologists in 3 certification groups recorded case logs, including 2,275 for initial certification, 2,381 for first recertification and 1,964 for second recertification. A total of 441,162 procedures were logged, of which 54.2% were ureteroscopy, 41.3% were shock wave lithotripsy and 4.5% were percutaneous nephrolithotomy. From 2003 to 2013 there was an increase in ureteroscopy from 40.9% to 59.6% and a corresponding decrease in shock wave lithotripsy from 54% to 36.3%. For new urologists ureteroscopy increased from 47.6% to 70.9% of all stones cases logged and for senior clinicians ureteroscopy increased from 40% to 55%. Endourologists performed a significantly higher proportion of percutaneous nephrolithotomies than nonendourologists (10.6% vs 3.69%, p <0.0001) and a significantly smaller proportion of shock wave lithotripsies (34.2% vs 42.2%, p = 0.001). Junior and senior clinicians showed a dramatic adoption of endoscopic techniques. Treatment of upper tract calculi is an evolving field and provider specific attributes affect how these stones are treated.

    Stroke, as a major risk factor for chronic impairment of upper limb function, can severely restrict the activities of daily living. Recently, robotic devices have been used to enhance the functional upper extremity movement of stroke patients. The purpose of the current study was to assess whether a robot-assisted reach training program using a whole arm manipulator (WAM) could improve upper extremity kinematic performance and functional movement for chronic stroke patients. Using a single-group design, this study followed 10 people with chronic stroke (6 men, 61.5 years; Mini-Mental State Examination score: 27.0; onset duration: 8.9 years). WAM with seven degrees of freedom for the shoulder, elbow, and wrist joints was used during robot-assisted reach exercises. Subjects participated in the training program for 40 minutes per day, 2 times a week, for 4 weeks. The main outcome measures were upper extremity kinematic performance (movement velocity) for three directions and functional movement (Action Research Arm Test). Upper extremity kinematic performance and functional movement measures were performed three times: at baseline, during intervention (at 2 weeks), and post intervention. Upper extremity kinematic performance and functional movement showed improvement after two weeks (P robot-assisted reach training on upper extremity kinematic performance as well as functional movement in individuals with chronic stroke. In addition, the findings of the current study may provide valuable information for subsequent randomized controlled trials.

    The purpose of this study was to compare postcontraction hyperemia after electrical stimulation between patients with upper extremity paralysis caused by upper motor neuron diseases and healthy controls. Thirteen healthy controls and eleven patients with upper extremity paralysis were enrolled. The blood flow in the basilic vein was measured by ultrasound before the electrical stimulation of the biceps brachii muscle and 30 s after the stimulation. The stimulation was performed at 10 mA and at a frequency of 70 Hz for 20 s. The mean blood flow in the healthy control group and in upper extremity paralysis group before the electrical stimulation was 60 ± 20 mL/min (mean ± SD) and 48 ± 25 mL/min, respectively. After the stimulation, blood flow in both groups increased to 117 ± 23 mL/min and 81 ± 41 mL/min, respectively. We show that it is possible to measure postcontraction hyperemia using an ultrasound system. In addition, blood flow in both groups increased after the electrical stimulation because of postcontraction hyperemia. These findings suggest that evaluating post contraction hyperemia in patients with upper extremity paralysis can assess rehabilitation effects.

    Gastrointestinal haemorrhage (GI) is a serious condition that presents both diagnostic as well as therapeutic challenges. Resuscitation of the patient is the first and most important step in its management followed by measures to localize and treat the exact source and site of bleeding. These modalities are upper and lower GI endoscopies, radionuclide imaging and angiography. Surgery is the last resort to handle the situation, if the patient does not respond to resuscitative measures and the various interventional procedures fail to locate and stop the bleeding. We present a case of upper GI bleeding which presented with massive per rectal bleeding and the patient was not responding to resuscitation with multiple blood transfusions. Ultimately an exploratory laparotomy was done which revealed an extra-intestinal source of bleeding into the lumen of duodenum, presenting as upper GI bleeding.

    Hypnosis is a therapeutic technique that primarily involves aRentive receptive concentration. Even though a small number of health professionals are trained in hypnosis and lingering myths and misconceptions associated with this method have hampered its widespread use to treat medical conditions, hypnotherapy has gained relevance as an effective treatment for irritable bowel syndrome not responsive to standard care. More recently, a few studies have addressed the potential influence of hypnosis on upper digestive function and disease. This paper reviews the efficacy of hypnosis in the modulation of upper digestive motor and secretory function. The present evidence of the effectiveness of hypnotherapy as a treatment for functional and organic diseases of the upper bowel is also summarized, coupled with a discussion of potential mechanisms of its therapeutic action.

    An upper dominating set in a graph is a minimal (with respect to set inclusion) dominating set of maximum cardinality.The problem of finding an upper dominating set is generally NP-hard, but can be solved in polynomial time in some restricted graph classes, such as P4-free graphs or 2K2-free graphs.For classes defined by finitely many forbidden induced subgraphs, the boundary separating difficult instances of the problem from polynomially solvable ones consists of the so called boundary classes.However, none of such classes has been identified so far for the upper dominating set problem.In the present paper, we discover the first boundary class for this problem.

    2011-01-01

    Nonvariceal upper gastrointestinal bleeding is unique from variceal bleeding in terms of patient characteristics, management, rebleeding rates, and prognosis, and should be managed differently. The majority of nonvariceal upper gastrointestinal bleeds will not rebleed once treated successfully. The incidence is 80 to 90% of all upper gastrointestinal bleeds and the mortality is between 5 to 10%. The causes include nonacid-related ulceration from tumors, infections, inflammatory disease, Mallory-Weiss tears, erosions, esophagitis, dieulafoy lesions, angiodysplasias, gastric antral vascular ectasia, and portal hypertensive gastropathy. Rarer causes include hemobilia, hemosuccus pancreaticus, and aortoenteric fistulas. Hematemesis and melena are the key features of bleeding from the upper gastrointestinal tract, but fresh per rectal bleeding may be present in a rapidly bleeding lesion. Resuscitation and stabilization before endoscopy leads to improved outcomes. Fluid resuscitation is essential to avoid hypotension. Though widely practiced, there is currently insufficient evidence to show that routine red cell transfusion is beneficial. Coagulopathy requires correction, but the optimal international normalized ratio has not been determined yet. Risk stratification scores such as the Rockall and Glasgow-Blatchford scores are useful to predict rebleeding, mortality, and to determine the urgency of endoscopy. Evidence suggests that high-dose proton pump inhibitors (PPI) should be given as an infusion before endoscopy. If patients are intolerant of PPIs, histamine-2 receptor antagonists can be given, although their acid suppression is inferior. Endoscopic therapy includes thermal methods such as coaptive coagulation, argon plasma coagulation, and hemostatic clips. Four quadrant epinephrine injections combined with either thermal therapy or clipping reduces mortality. In hypoxic patients, endoscopy masks allow high-flow oxygen during upper gastrointestinal endoscopy. The

    Full Text Available Nonvariceal upper gastrointestinal bleeding is unique from variceal bleeding in terms of patient characteristics, management, rebleeding rates, and prognosis, and should be managed differently. The majority of nonvariceal upper gastrointestinal bleeds will not rebleed once treated successfully. The incidence is 80 to 90% of all upper gastrointestinal bleeds and the mortality is between 5 to 10%. The causes include nonacid-related ulceration from tumors, infections, inflammatory disease, Mallory-Weiss tears, erosions, esophagitis, dieulafoy lesions, angiodysplasias, gastric antral vascular ectasia, and portal hypertensive gastropathy. Rarer causes include hemobilia, hemosuccus pancreaticus, and aortoenteric fistulas. Hematemesis and melena are the key features of bleeding from the upper gastrointestinal tract, but fresh per rectal bleeding may be present in a rapidly bleeding lesion. Resuscitation and stabilization before endoscopy leads to improved outcomes. Fluid resuscitation is essential to avoid hypotension. Though widely practiced, there is currently insufficient evidence to show that routine red cell transfusion is beneficial. Coagulopathy requires correction, but the optimal international normalized ratio has not been determined yet. Risk stratification scores such as the Rockall and Glasgow-Blatchford scores are useful to predict rebleeding, mortality, and to determine the urgency of endoscopy. Evidence suggests that high-dose proton pump inhibitors (PPI should be given as an infusion before endoscopy. If patients are intolerant of PPIs, histamine-2 receptor antagonists can be given, although their acid suppression is inferior. Endoscopic therapy includes thermal methods such as coaptive coagulation, argon plasma coagulation, and hemostatic clips. Four quadrant epinephrine injections combined with either thermal therapy or clipping reduces mortality. In hypoxic patients, endoscopy masks allow high-flow oxygen during upper

    Full Text Available OBJECTIVE : To study the pattern of upper gastrointestinal (GI malignancies in Tripura . METHODOLOGY: The study was conducted at the dept. of Medicine, Agartala Govt Medical College. All the patient s who underwent upper GI Endoscopy and were found to have an upper GI malignancy on histopathology were reviewed for the part of the gut involved. Patient’s demographics including age, clinical presentation, histological diagnosis and type were evaluated. RESULT: During the study period 95 cases of upper GI malignancy were seen in our institute. Total 7.36% cases were below 40 year of age. Mean patient age was 62.43 years. Among all the cases, 61.06% were esophageal carcinoma & 38.94% cases were gastric carcinoma. Mean patient age for oesophageal carcinoma is 58.37and 68.78 years respectively. Among the gastric carcinoma, 51.35% were in fundus, 32.43% in body and 16.21% in pyloric end and all were adenocarcinoma in histological type. In oesophageal carcinoma, upper third, middle third and lower third of oesophagus were involved in 15.51%, 62.06% and 24.13% of cases respectively and histologically 86.21% were squamous cell carcinoma whereas 13.79% were adenocarcinoma. CONCLUSION: Oesophageal carcinoma is more common than gastric carcinoma in this region and squamous type of esophageal carcinoma is the dominant type and fundal part is the most frequent site for gastric carcinoma. Endoscopic screening in subjects suspected of upper GI malignancy results in significant yield of carcinoma.

    Upper airway obstruction is a frequent problem in spontaneously breathing children undergoing anesthesia or sedation procedures. Failure to maintain a patent airway can rapidly result in severe hypoxemia, bradycardia, or asystole, as the oxygen demand of children is high and oxygen reserve is low. We present two children with cervical masses in whom upper airway obstruction exaggerated while the jaw thrust maneuver was applied during induction of anesthesia. This deterioration in airway patency was probably caused by medial displacement of the lateral tumorous tissues which narrowed the pharyngeal airway.

    2006-01-01

    We observe a net loss of 3.2 (+/- 1.1) x 1022 J of heat from the upper ocean between 2003 and 2005. Using a broad array of in situ ocean measurements, we present annual estimates of global upper-ocean heat content anomaly from 1993 through 2005. Including the recent downturn, the average warming rate for the entire 13-year period is 0.33 +/- 0.23 W/m2 (of the Earth's total surface area). A new estimate of sampling error in the heat content record suggests that both the recent and previous global cooling events are significant and unlikely to be artifacts of inadequate ocean sampling.

    2009-01-01

    Full Text Available A combination of techniques are required to adequately anaesthetise upper airway structures for awake intubation . The widest coverage is provided by the inhalational technique. This technique, however, does not always provide a dense enough level of anaesthesia for all patients. Supplementation of this technique with any of the specific nerve blocks is an excellent way to accomplish efficacious anaesthesia for awake inubation. Anaesthetising upper airway is not a difficult skill to master and should be in the armamentarium of all practising anaesthetist.

    Over the course of childhood, children's thinking about social groups changes in a variety of ways. Developmental Subjective Group Dynamics (DSGD) theory emphasizes children's understanding of the importance of conforming to group norms. Abrams et al.'s study, which uses DSGD theory as a framework, demonstrates the social cognitive skills underlying young elementary school children's thinking about group norms. Future research on children's thinking about groups and group norms should explore additional elements of this topic, including aspects of typicality beyond loyalty.

    The Dahongshan Group is divided into five formations from the bottom to the top:the Laochanghe For-mation;the Manganghe Formation;the Hongshan Formation ,the Feiweihe Formation and the Potou For-mation.As can be seen form the U-Pb Concordia plot for zircon fractions collected from the metamorphic sodic lava of the Hongshan Formation,the upper intersect age with the Concordia is 1665.55-10.86+13.56Ma.Sm-Nd dating of four whole-rock samples and one hornblende from the Manganghe and Hongshan forma-tions yielded an isochron age of 1657±82Ma .This result is in good agreement with the zircon U-Pb age and thus can represent the formation age of the Dahongshan Group.The initial143Nd/144Nd ratio is esti-mated at 0.510646,with END(T)=+3.1±1.8.In addition the Dahongshan Group rocks are character-ized by low REE contents,with δEu>1.All this goes to show that the original rocks of the Dahongshan Group were derived from a depleted mantle.The calculated Sm-Nd model ages range from-1900 to -2000Ma,representing the time of crust/mantle differentiation in the area studied.From the above results,in conjunction with the time-scale scheme for China,the Dahongshan Group should be assigned to the Middle Proterozoic.

    2005-01-01

    Full Text Available Background and purpose : Apical residual air space and prolonged air leakage are not uncommon entities following resection of upper lobe of the lung. This study was carried out to observe the efficacy of the pleural tenting in preventing complications.Materials and methods : This is a case series study that compared with historical control. Pleural tenting after upper or upper and middle lobectomies was performed in 10 patients. In another 12 patients who underwent upper lobectomy or bilobectomy, pleural tenting was not performed. Both groups were compared with respect to duration of post operative air leak, drainage and hospital stay and need for any additional intervention for prolonged airleak. Results : Age, sex, pathology and pulmonary function test of two groups were similar. Duration of the chest tube air leakage was shorter in those pleural tenting was performed on when compared to whom pleural tenting was not performed (2.6 ± 1.1 days versus 9.1 ± 8.1 days. Mean hospital stay was shorter in tented group (5.2 ± 1 days versus 10.8 ± 7.5.Conclusion : Pleural tenting following upper lobectomy or bilobectomy of the lung shortens the duration of the chest tube drainage and hospital stay and it prevents apical residual airspace and related complications. Pleural tenting is a safe and relatively simple procedure, which has no associated morbidity.

    During smile evaluation and anterior esthetic construction, the anatomic and racial variations should be considered in order to achieve better matching results. The aims of this study were to validate an objective method for recording spontaneous smile process and to categorize the smile and upper lip curvature of Chinese Han-nationality youth. One hundred and eighty-eight Chinese Han-nationality youths (88 males and 100 females) ranged from 20 to 35 years of age were selected. Spontaneous smiles were elicited by watching comical movies and the dynamics of the spontaneous smile were captured continuously with a digital video camera. All subjects' smiles were categorized into three types: commissure, cuspid and gummy smile based on video editing software and final images. Subjects' upper lip curvatures were also measured and divided into three groups: upward, straight and downward. Reliability analysis was conducted to obtain intra-rater reliabilities on twice measurements. The Pearson Chi-square test was used to compare differences for each parameters (α=0.05). In smile classification, 60.6% commissure smile, 33.5% cuspid smile and 5.9% gummy smile were obtained. In upper lip measurement, 26.1% upward, 39.9% straight and 34.0% downward upper lip curvature were determined. The commissure smile group showed statistically significant higher percentage of straight (46.5%) and upward (40.4%) in upper lip curvatures (P〈0.05), while cuspid smile group (65.1%) and gummy smile group (72.7%) showed statistically significant higher frequency in downward upper lip curvature (P〈0.05). It is evident that differences in upper lip curvature and smile classification exist based on race, when comparing Chinese subjects with those of Caucasian descent, and gender.

    Background Delineating the nodal clinical target volume (ctvn) remains a challenging task in patients with cervical or upper thoracic esophageal carcinoma (ec). In particular, the extent of the lymph area that should be included in the irradiation field remains controversial. In the present study, the extent of the ctvn was determined based on the incidence of lymph node involvement mapped by computed tomography (ct) imaging. Methods Our study included 468 patients who were diagnosed with cervical and upper thoracic ec and who received staging information between June 2005 and April 2011. The anatomic distribution of metastatic regional lymph nodes was mapped using ct images and grouped using the levels established by the Radiation Therapy Oncology Group. The probability of the various groups being involved was examined. If a lymph node group had a probability of 10% or more of being involved, it was considered at high risk for metastasis, and elective treatment as part of the ctvn was recommended. Results Lymph node involvement was mapped by ct in 256 patients (54.7%). Not all lymph node groups should be included in the ctvn. For cervical lesions, the involved lymph nodes were located mainly between the hyoid bone and the arcus aortae; the recommended ctvn should consist of the neck lymph nodes at levels iii and iv (supraclavicular group) and thoracic groups 2 and 3P. In upper thoracic ec patients, most of the involved lymph nodes were distributed between the cricoid cartilage and the subcarinal area; the ctvn should cover the supraclavicular group and thoracic nodal groups 2, 3P, 4, 5, and 7. Conclusions Our ct-based study indicates a specific distribution and incidence of metastatic lymph node groups in patients with cervical and upper thoracic ec. The results suggest that regional lymph node groups should be electively included in the ctvn for precise radiation administration. PMID:26089729

    [Purpose] The purpose of this study was to determine the effects of mirror therapy with tasks on upper extremity unction and self-care in stroke patients. [Subjects] Thirty participants were randomly assigned to either an experimental group (n=15) or a control group (n=15). [Methods] Subjects in the experimental group received mirror therapy with tasks, and those in the control group received a sham therapy; both therapies were administered, five times per week for six weeks. The main outcome measures were the Manual Function Test for the paralyzed upper limb and the Functional Independence Measure for self-care performance. [Results] The experimental group had more significant gains in change scores compared with the control group after the intervention. [Conclusion] We consider mirror therapy with tasks to be an effective form of intervention for upper extremity function and self-care in stroke patients.

    2016-04-01

    With more than 150 million people living within 1 m of high tide future sea level rise is one of the most damaging aspects of warming climate. The latest Intergovernmental Panel on Climate Change report (AR5 IPCC) noted that a 0.5 m rise in mean sea level will result in a dramatic increase the frequency of high water extremes - by an order of magnitude, or more in some regions. Thus the flood threat to the rapidly growing urban populations and associated infrastructure in coastal areas are major concerns for society. Hence, impact assessment, risk management, adaptation strategy and long-term decision making in coastal areas depend on projections of mean sea level and crucially its low probability, high impact, upper range. With probabilistic approach we produce regional sea level projections taking into account large uncertainties associated with Greenland and Antarctica ice sheets contribution. We calculate the upper limit (as 95%) for regional sea level projections by 2100 with RCP8.5 scenario, suggesting that for the most coastlines upper limit will exceed the global upper limit of 1.8 m.

La discontinuidad neta y planar y el importante cambio en la arquitectura fluvial sugieren una fuerte disminución en la relación acomodación/suministro.The Río Neuquén Subgroup (lateTuronian-late Coniacian of the Neuquén Group, crops out to the west of the Senillosa locality. Sedimentological studies in order to determine paleoenvironments, their evolution, and relevant controls on deposition were carried out in this area. Twelve lithofacies were defined and included in six facies associations. The nature and arrangement of facies associations suggest the development of braided and anastomosig fluvial systems as well as dunes and aeolian sandsheets. The fluvial systems were subject to changes in the discharge regime, interpreted to be related to short term climatic variability. The variations of dominant grain size of the bed load, thickness of channel bodies, and relative proportions of channel/flood plain elements, respond to long term fluctuations of discharge levels. It is suggested that the modifications in base-level controlled the large-scale fluvial architecture. At the base of Portezuelo Formation thick channels show a braided design, levees, crevasse splay and a strong multilateral relation are developed. These relation of channel units, is related with a rate of sediment supply that, in general, compensated by the subsidence rate. At the flood plain aeolian dunes and sheet were developed. Gradually, a decreasing on the channel/floodplain relation is recorded. The fluvial system is characterized by isolate lenticular channels in flood plain deposits and frequent crevasse splays events.were recorded. In the top of the unit, an increase of subsidence rate resulted in the development of flooded areas within the flood plain and the anastomosed fluvial style. At

    AIM: To study the preoperative and postoperative role of upper esophagogastroduodenoscopy (EGD) in morbidly obese patients. METHODS: This is a multicenter retrospective study by reviewing the database of patients who underwent bariatric surgery (laparoscopic sleeve gastrectomy, laparoscopic Roux en Y gastric bypass, or laparoscopic minigastric bypass) in the period between 2001 June and 2015 August (Jahra Hospital-Kuwait, Hafr Elbatin Hospital and King Saud Medical City-KSA, and Mansoura University Hospital - Egypt). Patients with age 18-65 years, body mass index (BMI) > 40, or > 35 with comorbidities after failure of many dietetic regimen and acceptable levels of surgical risk were included in the study after having an informed signed consent. We retrospectively reviewed the medical charts of all morbidly obese patients. The patients’ preoperative data included clinical history including upper digestive symptoms and preoperative full workup including EGD. Only patients whose charts revealed weather they were symptomatic or not were studied. We categorized patients accordingly into two groups; with (group A) or without (group B) upper digestive symptoms. The endoscopic findings were categorized into 4 groups based on predetermined criteria. The medical record of patients who developed stricture, leak or bleeding after bariatric surgery was reviewed. Logestic regression analysis was used to identify preoperative predictors that might be associated with abnormal endoscopic findings. RESULTS: Three thousand, two hundred and nineteen patients in the study period underwent bariatric surgery (75% LSG, 10% LRYDB, and 15% MGB). Mean BMI was 43 ± 13, mean age 37 ± 9 years, 79% were female. Twenty eight percent had presented with upper digestive symptoms (group A). EGD was considered normal in 2414 (75%) patients (9% group A vs 66% group B, P = 0.001). The abnormal endoscopic findings were found high in those patients with upper digestive symptoms.

    [Purpose] The purpose of this study was to observe the effects of stretching the upper trapezius muscle on the asymmetric rate of bite force. [Subjects] Forty-seven female university students who had all their original teeth, had no disorders in the temporomandibular joints, and had never worn braces; participated in this study. [Methods] An occlusometer was used to measure biting forces. Subsequently, stretching exercises of the upper trapezius were performed. The subjects were divided into 3 groups at the start of the testing: the asymmetric rate of the first group was less than 10%; the asymmetric rate of the second group was between 10% and 20%; and the asymmetric rate of the third group was more than 20%. The stretching exercises were done on the dominant side of the upper trapezius. [Results] After the stretching exercises of the upper trapezius, the results showed that for the first group, whose asymmetric rate of biting force was less than 10%, there was a significant increase in asymmetric rate (from 5.1% to 10.3%). For the second group, whose asymmetric rate of biting force was measured to be between 10% and 20%, the asymmetric rate decreased from 14.7% to 14.3%, but the change was not statistically significant. For the third group, whose asymmetric rate of biting force was more than 20%, there was a significant decrease in asymmetric rate (from 27.8% to 12.6%). [Conclusion] We concluded that stretching exercises of the upper trapezius muscle had a direct effect on the asymmetric rate of biting force.

    Major ozonated autohemotherapy is classically used in treating ischemic disorder of the lower limbs. In the present study, we performed major ozonated autohemotherapy treatment in patients with acute cerebral infarction, and assessed outcomes according to the U.S. National Institutes of Health Stroke Score, Modified Rankin Scale, and transcranial magnetic stimulation motor-evoked potential. Compared with the control group, the clinical total effective rate and the cortical potential rise rate of the upper limbs were significantly higher, the central motor conduction time of upper limb was significantly shorter, and the upper limb motor-evoked potential amplitude was significantly increased, in the ozone group. In the ozone group, the National Institutes of Health Stroke Score was positively correlated with the central motor conduction time and the motor-evoked potential amplitude of the upper limb. Central motor conduction time and motor-evoked potential amplitude of the upper limb may be effective indicators of motor-evoked potentials to assess upper limb motor function in cerebral infarct patients. Furthermore, major ozonated autohemotherapy may promote motor function recovery of the upper limb in patients with acute cerebral infarction.

    Injection of CO2 into underground rock formations can reduce atmospheric CO2 emissions. Caprocks present above potential storage formations are the main structural trap inhibiting CO2 from leaking into overlying aquifers or back to the Earth's surface. Dissolution and precipitation of caprock minerals resulting from reaction with CO2 may alter the pore network where many pores are of the micrometer to nanometer scale, thus altering the structural trapping potential of the caprock. However, the distribution, geometry and volume of pores at these scales are poorly characterized. In order to evaluate the overall risk of leakage of CO2 from storage formations, a first critical step is understanding the distribution and shape of pores in a variety of different caprocks. As the caprock is often comprised of mudstones, we analyzed samples from several mudstone formations with small angle neutron scattering (SANS) and high-resolution transmission electron microscopy (TEM) imaging to compare the pore networks. Mudstones were chosen from current or potential sites for carbon sequestration projects including the Marine Tuscaloosa Group, the Lower Tuscaloosa Group, the upper and lower shale members of the Kirtland Formation, and the Pennsylvanian Gothic shale. Expandable clay contents ranged from 10% to approximately 40% in the Gothic shale and Kirtland Formation, respectively. During SANS, neutrons effectively scatter from interfaces between materials with differing scattering length density (i.e., minerals and pores). The intensity of scattered neutrons, I(Q), where Q is the scattering vector, gives information about the volume and arrangement of pores in the sample. The slope of the scattering data when plotted as log I(Q) vs. log Q provides information about the fractality or geometry of the pore network. On such plots slopes from -2 to -3 represent mass fractals while slopes from -3 to -4 represent surface fractals. Scattering data showed surface fractal dimensions

  9. Group theories: relevance to group safety studies.

    Promoting safety in the workplace has been attempted in a variety of ways. Increasingly, industries are using groups such as safety teams and quality circles to promote worker safety. Group influences on individual behavior and attitudes have long been studied in the social psychology literature, but the theories have not been commonly found outside the psychology arena. This paper describes the group theories of group polarization, risky shift, social loafing, groupthink and team think and attempts to apply these theories to existing studies that examine work group influences on safety. Interesting parallels were found but only one study examined group influences as their primary focus of research. Since groups are increasingly used for safety promotion, future research on safety that studies group influences with respect to current group theories is recommended.

    Full Text Available Sulphide inclusions, which represent melts trapped in the minerals of magmatic rocks and xenoliths, provide important clues to the behaviour of immiscible sulphide liquids during the evolution of magmas and the formation of Ni–Cu–Fe deposits. We describe sulphide inclusions from unique ultramafic clots within mafic xenoliths, from the mafic xenoliths themselves, and from the three silica-rich host plutons in Tongling, China. For the first time, we are able to propose a general framework model for the evolution of sulphide melts during the evolution of mafic to felsic magmas from the upper mantle to the upper crust. The model improves our understanding of the sulphide melt evolution in upper mantle to upper crust magmas, and provides insight into the formation of stratabound skarn-type Fe–Cu polymetallic deposits associated with felsic magmatism, thus promising to play an important role during prospecting for such deposits.

    Gowers in his paper on quasirandom groups studies a question of Babai and Sos asking whether there exists a constant $c > 0$ such that every finite group $G$ has a product-free subset of size at least $c|G|$. Answering the question negatively, he proves that for sufficiently large prime $p$, the group $\\mathrm{PSL}_2(\\mathbb{F}_p)$ has no product-free subset of size $cn^{8/9}$, where $n$ is the order of $\\mathrm{PSL}_2(\\mathbb{F}_p)$. We will consider the problem for compact groups and in particular for profinite groups $\\SL_k(\\ZZ_p)$ obtain lower and upper exponential bounds for the supremal measure of the product-free sets. The proof involves establishing a lower bound for the dimension of non-trivial representations of the finite groups $\\SL_k(\\Z{p^n})$.

    Rehabilitation of upper limb in patients after ischemic stroke is a major challenge for modern neurorehabilitation. Function of upper limb of patients after ischemic stroke returns on the end of the rehabilitation comparing with another parts of the body. Below presents two groups of patients after ischemic stroke who were rehabilitated with use of the following methods: kinesiotherapy combined with NDT- Bobath method and kinesiotherapy only. The aim of this study was to assess the impact of kinesiotherapy only and NDT- Bobath method combined with kinesiotherapy on the functional state and muscle tone of upper limb in patients after ischemic stroke. The study involved a group of 40 patients after ischemic stroke with motor control and muscle tone problems of upper limb. Patients were divided into two groups, each of them included 20 people. Upper limb in group I was rehabilitated with the use of kinesiotherapy exercise however group II with the use of kinesiotherapy exercise combined with NDT- Bobath method (Neurodevelopmental Treatment Bobath). To evaluate the patients before and after rehabilitation muscle tone Asworth scale was used and to assess functional status Rivermead Motor Assessment (RMAIII) scale was used. After 5 weeks of rehabilitation in group II in majority patients were observed decrease of muscle tone and improvement in upper limb functional status. In group I the muscle tone were also decreased and functional status were better but in smaller impact than in II group. Classical kinesiotherapy combined with the NDT-Bobath method gives better results in neurorehabilitation of upper limb than the use of kinesiotherapy exercises only in patients after ischemic stroke.

Patients and Methods This is an 8year retrospective review of foreign body in upper aero-digestive tract of children (January 2001 to December 2007 was conducted at the ENT department of the University of Ilorin Teaching Hospital, Ilorin, Nigeria. Case notes of the patients were retrieved and the following were data extracted: demographic, clinical, operative and outpatient visits outcome. Results 81 children aged 9months to löyears were seen (mean 4.28, SD 2.95 with 49 males and 32 females and a male: female ratio of 1.5: 1.0.The commonest age group was 9months to 4years (76.5%. Most common of impaction sites were nasal cavity in 31 cases (38.3%, oesophagus in 23 cases (28.4%, oropharynx in 16 (19.8% and larynx in 6 (7.4%.The commonest FBs was coins in 33 (40.7% in the oesophagus and 37.5% of pharyngeal FBs. Inanimate FBs in the nose constituted 31(38.3% [Non vegetative 27(87.1%, vegetative 4(12.9 %]. Fish bones were seen in 11 cases (13.6% [6 in the larynx and 5 around the tonsillar fauces] and miscellaneous objects in 6 cases. Conclusion Upper aero-digestive foreign bodies are common especially among the under fours′, commonest sites being the nose and pharyngooesophageal region with coins and inanimate FBs constituting about four-fifth. There is the need for parental health education on object placements, and a high index of suspicion among practitioners to facilitate early referral and avoid preventable complications.

    Four of the 16 ITER upper port plugs will be devoted to electron cyclotron resonance heating (ECRH) in order to control magnetohydrodynamic (MHD) instabilities . In order to achieve the stabilisation of the neoclassical tearing modes (NTM) and sawtooth oscillation, a deposition of a very localized and peaked current density profile over a broad poloidal steering range is required. In the present optical configuration eight 2 MW mm-wave beams enter each of the four upper launchers (UL) through waveguides into the vacuum vessel. Each beam line comprises consecutive corrugated waveguide sections with two mitre bends, orientating the poloidal and toroidal directions and three sections of quasi-optical transmission . The beam waist locations and beam shaping properties in free space propagation are defined by two additional mirrors, the first being a static focusing mirror and the second a plane poloidally steerable mirror. Each mirror reflects a group of 4 mm-wave beams. The three types of UL mirrors (mitre bend, focusing and steering) absorb heat generated essentially by three sources: the ohmic loss of the RF beam reflected at the mirror surfaces and the nuclear and thermal radiation coming from the plasma. While the average heat load is within reasonable engineering limits, three elements condition the actual mirror design, the peak ohmic heat load (Gaussian or Bessel type heat deposition profiles), the electromagnetic forces generated in vertical disruption events (VDE), and the ITER cooling water requirements. This paper provides an overview of the different upper port-plug mirror designs and cooling schemes and an outlook on the prototype manufacturing activities and the future test program. The optimized mm-wave layout within the ECH port plugs is also presented.

    Recent empirical research has revealed differences in functional capacity between the upper and lower visual fields (VFs), with the lower VF exhibiting superiority in visual perception skills. Similarly, functional differences between the left and right hemispheres elicit a predominance for visuospatial processing in the left visual field (left VF). Both anatomical as well as evolutionary arguments have been adopted in accounting for these variations in function. Preceding upper and lower VF research has typically investigated either static stimulus perception or the visual processing of upper limb action. The aim of the current research was to investigate whether the lower VF benefits associated with limb control transcend to visual anticipation (the perception of motion). Methods were based on Khan and Lawrence (Exp Brain Res 164:395-398, 2005), who investigated upper/lower VF differences in visuomotor control, but utilising a representational momentum paradigm to isolate perceptual processes. Thirty-two participants were randomised into either a left or right VF group and completed a perceptual computer-based task in the upper and lower VF, where they were required to judge the final position of a moving object before it disappeared. Two aspects of the distributions of same responses were then analysed; the central tendency (weighted means) and the variability. Results revealed that in the left VF, weighted means for the lower VF were significantly greater than for the upper VF [t(14) = 2.242, p = 0.042]. In both left and right VFs, variability was greater in the upper compared to lower VF. This provides new findings regarding visual processes in the different visual fields. While visual search and large scene perception has been found to be superior in the upper VF, here we find that visual anticipation, like target-directed visuomotor skill, is superior in the lower VF.

    Patients with significant medical and social problems resulting from impaired perfusion of the upper limbs caused by micro- or macro-angiopathy are now frequent in clinical practice. Vasospastic disease of the upper limbs of combined origin is a difficult condition to treat by conservative methods and therapeutic strategies are usually multidisciplinary. In addition to standard pharmacotherapy, treatment may involve regional anaesthesia, thoracoscopic or radiofrequency sympathectomy and surgical treatment of defects, including plastic surgery. This paper describes our successful work in the treatment of upper limb critical ischemia using radiofrequency upper thoracic sympathectomy. In three case reports we present the results of radiofrequency thermolysis applied to treat patients with chronic defects of the hand and fingers. These patients were diagnosed with upper limb critical ischemia of combined origin, standard conservative treatment methods failed and surgical intervention was originally not indicated, however, radiofrequency thermolysis proved to be beneficial. Radiofrequency thoracic sympathectomy could improve peripheral perfusion of the upper limbs and thereby contribute to healing of chronic defects, reduction of pain and improvement in the quality of life of the patients.

    Left untreated, paralytic lagophthalmos may result in corneal dryness, ulcerations, and subsequent blindness. The most common nondynamic surgical solution is upper eyelid weight placement in a superficial, pretarsal pocket, carrying the risk of visibility, extrusion, and entropion. The authors present a technique useful in patients presenting with either primary symptoms of corneal exposure or complications of previous implants that is equally efficacious, with a potentially decreased risk of complications, in which the weight is inserted into a deeper, postseptal position but requires use of a heavier weight. Nineteen patients, 15 primary and four secondary, treated between the years 2008 and 2012 with the postseptal approach, were evaluated for demographics, cause, resolution of primary symptoms, and complications. The average weight difference between that measured in the clinic versus weight used in surgery in the primary group and the average weight difference between that inserted in previous surgery versus weight placed in corrective surgery were calculated. The average weight difference was 0.213 g (range, 0 to 0.4 g) in the primary group and 0.2 g (range, 0 to 0.4 g) in the revision group. Symptoms resolved in all but one patient, neither revisions nor complications were noted, and the longest follow-up was 4 years. The retroseptal technique has proven to be safe, reproducible, and very useful in both primary and secondary upper eyelid surgery for paralytic lagophthalmos. It successfully addresses several common problems encountered with more superficial weight placement, including visibility, exposure, and entropion, but often necessitates use of a heavier weight.

  18. Effects of sedation during upper gastrointestinal endoscopy on endocrine response and cardiorespiratory function

    Full Text Available Upper gastrointestinal endoscopy is often accompanied by tachycardia which is known to be an important pathogenic factor in the development of myocardial ischemia. The pathogenesis of tachycardia is unknown but the condition is thought to be due to the endocrine response to endoscopy. The purpose of the present study was to investigate the effects of sedation on the endocrine response and cardiorespiratory function. Forty patients scheduled for diagnostic upper gastrointestinal endoscopy were randomized into 2 groups. While the patients in the first group did not receive sedation during upper gastrointestinal endoscopy, the patients in the second group were sedated with intravenous midazolam at the dose of 5 mg for those under 65 years or 2.5 mg for those aged 65 years or more. Midazolam was administered by slow infusion. In both groups, blood pressure, ECG tracing, heart rate, and peripheral oxygen saturation (SpO2 were monitored during endoscopy. In addition, blood samples for the determination of cortisol, glucose and C-reactive protein levels were obtained from patients in both groups prior to and following endoscopy. Heart rate and systolic arterial pressure changes were within normal limits in both groups. Comparison of the two groups regarding the values of these two parameters did not reveal a significant difference, while a statistically significant reduction in SpO2 was found in the sedation group. No significant differences in serum cortisol, glucose or C-reactive protein levels were observed between the sedated and non-sedated group. Sedation with midazolam did not reduce the endocrine response and the tachycardia developing during upper gastrointestinal endoscopy, but increased the reduction in SpO2.

    Many patients with acute gastrointestinal bleeding present with anemia and frequently require red blood cell (RBC) transfusion. A restrictive transfusion strategy and a low hemoglobin (Hb) threshold for transfusion had been shown to produce acceptable outcomes in patients with acute upper gastrointestinal bleeding. However, most patients are discharged with mild anemia owing to the restricted volume of packed RBCs (pRBCs). We investigated whether discharge Hb influences the outcome in patients with acute nonvariceal upper gastrointestinal bleeding. We retrospectively analyzed patients with upper gastrointestinal bleeding who had received pRBCs during hospitalization between January 2012 and January 2014. Patients with variceal bleeding, malignant lesion, stroke, or cardiovascular disease were excluded. We divided the patients into 2 groups, low (8 g/dL ≤ Hb  10 g/dL. Patients in the low Hb group had a lower consumption of pRBCs and shorter hospital stay than did those in the high Hb group. The Hb levels were not fully recovered at outpatient follow-up until 7 days after discharge; however, most patients showed Hb recovery at 45 days after discharge. The rate of rebleeding after discharge was not significantly different between the 2 groups. In patients with acute upper gastrointestinal bleeding, a discharge Hb between 8 and 10 g/dL was linked to favorable outcomes on outpatient follow-up. Most patients recovered from anemia without any critical complication within 45 days after discharge.

    [Purpose] This study aims to describe a protocol based on neurocognitive therapeutic exercises and determine its feasibility and usefulness for upper extremity functionality when compared with a conventional protocol. [Subjects and Methods] Eight subacute stroke patients were randomly assigned to a conventional (control group) or neurocognitive (experimental group) treatment protocol. Both lasted 30 minutes, 3 times a week for 10 weeks and assessments were blinded. Outcome measures included: Motor Evaluation Scale for Upper Extremity in Stroke Patients, Motricity Index, Revised Nottingham Sensory Assessment and Kinesthetic and Visual Imagery Questionnaire. Descriptive measures and nonparametric statistical tests were used for analysis. [Results] The results indicate a more favorable clinical progression in the neurocognitive group regarding upper extremity functional capacity with achievement of the minimal detectable change. The functionality results are related with improvements on muscle strength and sensory discrimination (tactile and kinesthetic). [Conclusion] Despite not showing significant group differences between pre and post-treatment, the neurocognitive approach could be a safe and useful strategy for recovering upper extremity movement following stroke, especially regarding affected hands, with better and longer lasting results. Although this work shows this protocol's feasibility with the panel of scales proposed, larger studies are required to demonstrate its effectiveness.

    AIM: To investigate the feasibility of treatment for upper gastrointestinal fistula and leakage with personal stage nutrition support.METHODS: Forty-three patients with upper gastrointestinal fistula and leakage were randomly divided into two groups. Patients in group A were treated with personal stage nutrition support and patients in group B were treated with total parental nutrition (TPN) in combination with operation.Nutritional states of the candidates were evaluated by detecting albumin (Alb) and pre-Alb. The balance between nutrition and hepatic function was evaluated by measurement of aspartate aminotransferase (AST),alanine aminotransferase (ALT) and total bilirubin (Tbill) before and after operation. At the same time their complications and hospitalized time were surveyed.RESULTS: Personal stage nutrition support improved upper gastrointestinal fistula and leakage. The nutrition state and hepatic function were better in patients who received personal stage nutrition support than in those who did not receive TPN. There was no significant difference in the complication and hospitalized time in the two groups of patients.CONCLUSION: Upper gastrointestinal fistula and leakage can be treated with personal stage nutrition support which is more beneficial for the post-operation recovery and more economic than surgical operation.

    Full Text Available Robotics not only contributes to the invention of rehabilitation devices, it can also enhance the quality of medical education. In recent years, the use of patient simulators and part-task trainers in the medical education field has brought meaningful improvements in the training of medical practitioners. Nevertheless, in the context of therapy training for upper limb disorders, trainee therapists still have to engage directly with the patients to gain experience of the rehabilitation of physical diseases. In this work, a high-fidelity part-task trainer that is able to reproduce the stiffness of spasticity and rigidity symptoms of the upper limb, such as those observed in post-stroke patients and Parkinson's disease patients, has been developed. Based on the evaluation carried out by two experienced therapists, the developed part-task trainer is able to simulate different patient cases and help trainee therapists gain pre-clinical experience in a safe and intuitive learning environment.

    2009-07-01

    We introduce Endoscopic Low Coherence Interferometry to obtain topology of upper airways through commonly used rigid endoscopes. Quantitative dimensioning of upper airways pathologies is crucial to provide maximum health recovery chances, for example in order to choose the correct stent to treat endoluminal obstructing pathologies. Our device is fully compatible with procedures used in day-to-day examinations and can potentially be brought to bedside. Besides this, the approach described here can be almost straightforwardly adapted to other endoscopy-related field of interest, such as gastroscopy and arthroscopy. The principle of the method is first exposed, then filtering procedure used to extract the depth information is described. Finally, demonstration of the method ability to operate on biological samples is assessed through measurements on ex-vivo pork bronchi.

    2014-12-01

    A most fascinating result of recent ionospheric experiments has been the discovery of artificial ionization by Pedersen et al. (GRL, 37, L02106, 2010). The Artificial Ionospheric Layers (AIL) were the result of F-region O-mode HF irradiation using the HAARP ionospheric heater operating at 3.6 MW power. As demonstrated by Eliasson et al. (JGR, 117, A10321, 2012) the physics controlling the observed phenomenon and its threshold can be summarized as: " Collisional ionization due to high energy (~ 20 eV) electron tails generated by the interaction of strong Langmuir turbulence with plasma heated at the upper hybrid resonance and transported at the reflection height". The objective of the current presentation is to explore the role of the upper hybrid heating in the formation of AIL and its implications to future experiments involving HF heaters operating in middle and equatorial latitudes.

    2011-10-01

    The dominant forms of particles collected at altitudes of 39, 42 and 45km during three balloon flights over Australia were aggregates having components with diameters typically 40 to 50nm. Their partial electron transparency suggested an organic composition and all were accompanied by a volatile liquid that could be stabilised by reaction with a thin copper film. They closely resembled particles called "fluffy micrometeorites" collected earlier in the mesosphere from rockets and their properties were consistent with those of particles collected from a comet by a recent spacecraft experiment. Particles in the upper stratosphere included some that resembled viruses and cocci, the latter being one of the organisms cultured from upper stratospheric air in a recent experiment. A plausible source of the stratospheric, mesospheric and cometary aggregates is consistent with the "panspermia" theory, that microorganisms present in space at the birth of the solar system could have reproduced in water within comets and brought life to Earth.

    To evaluate the efficiency and safety of the cervical epidural blockade (CEB) in upper extremity surgery, using lidocaine 2%, bupivacaine 5% and a mixture of both local analgesics. Eighty five patients were submitted to upper limb surgery under CEB. They were assigned into one of three groups: group I received 100 mg of 2% lidocaine; group II received 30 mg of 0.5% bupivacaine, and group III received a mixture of 60 mg of 2% lidocaine and 15 mg of 0.5% bupivacaine. We evaluated their effects on vital signs, blockade quality, adverse effects, and patient comfort. Anesthesiologist and surgeon evaluated the technique as "good" in 80% of the patients. Significant differences were found for motor blockade. Group II developed complete motor block (100%). Observed adverse effects were vomiting in groups II and III and dural puncture was present in 6.7% of the cases in group II. This study confirms the safety of cervical epidural anesthesia for upper limb surgery using three different formulations of local anesthetics.

    [Purpose] This study aimed to evaluate the effectiveness of mirror therapy combined with a conventional rehabilitation program on upper extremity motor and functional recovery in stroke patients. [Subjects and Methods] Thirty-one hemiplegic patients were included. The patients were randomly assigned to a mirror (n=16) or conventional group (n=15). The patients in both groups underwent conventional therapy for 4 weeks (60-120 minutes/day, 5 days/week). The mirror group received mirror therapy, consisting of periodic flexion and extension movements of the wrist and fingers on the non-paralyzed side. The patients in the conventional group performed the same exercises against the non-reflecting face of the mirror. The patients were evaluated at the beginning and end of the treatment by a blinded assessor using the Brunnstrom stage, Fugl-Meyer Assessment (FMA) upper extremity score, and the Functional Independence Measure (FIM) self-care score. [Results] There was an improvement in Brunnstrom stage and the FIM self-care score in both groups, but the post-treatment FMA score was significantly higher in the mirror therapy group than in the conventional treatment group. [Conclusion] Mirror therapy in addition to a conventional rehabilitation program was found to provide additional benefit in motor recovery of the upper extremity in stroke patients.

    Reconstruction of large defects of the upper eyelid is challenging because of its complex anatomy and specialized function. The aim of this work is to develop a single-stage reconstruction procedure based on a new approach. The technique consists of the advancement of an orbicularis oculi myocutaneous flap designed within the blepharoplasty skin excision pattern. After the tumor's excision is completed with clear margins, the borders of the flap are incised down to the submuscular plane inside the classical pattern of upper eyelid blepharoplasty. Two myocutaneous triangles are excised on both sides of the flap to allow its advancement to cover the defect. When it is necessary to repair the posterior lamella, we harvest a mucochondral graft. From 2012 to 2015, we performed upper eyelid reconstruction with this technique on six patients. The flap survived in all the patients, without total or partial necrosis. No patient required surgical revision. The results were aesthetically satisfying, and no tumor recurrence was noted. Our new approach to upper eyelid reconstruction maximizes the cosmetic outcome respecting the principles of radicality. This flap is better suited for lesions involving the median or paramedian eyelid border from the marginal zone up to the palpebral crease. The approach we propose is safe and versatile, and it ensures either a functional or a good aesthetic reconstruction. This journal requires that authors assign a level of evidence to each article.

    Typhoon Kalmaegi passed over an array of buoys and moorings in the northern South China Sea in September 2014, leaving a rare set of observations on typhoon-induced dynamical and thermohaline responses in the upper ocean. The dynamical response was characterized by strong near-inertial currents with opposite phases in the surface mixed layer and in the thermocline, indicating the dominance of the response by the excitation of the first baroclinic mode. The thermohaline response showed considerable changes in the mean fields in addition to a near-inertial oscillation. In particular, temperature and salinity anomalies generally exhibited a three-layer vertical structure, with the surface layer becoming cooler and saltier, the subsurface layer warmer and fresher, and the lower layer cooler and saltier again. The response in the surface and subsurface layers was much stronger to the right of the typhoon track, while that in the lower layer was stronger along the track and to the left. These features of the upper ocean response were grossly reproduced by a three-dimensional numerical model. A model-based heat budget analysis suggests that vertical mixing was mainly responsible for the surface cooling and subsurface warming, while upwelling was the cause of cooling from below. Both observations and model results indicate that the whole upper ocean experienced an overall cooling in the wake of typhoon Kalmaegi.

  2. Anatomic Optical Coherence Tomography of Upper Airways

    The upper airway is a complex and intricate system responsible for respiration, phonation, and deglutition. Obstruction of the upper airways afflicts an estimated 12-18 million Americans. Pharyngeal size and shape are important factors in the pathogenesis of airway obstructions. In addition, nocturnal loss in pharyngeal muscular tone combined with high pharyngeal resistance can lead to collapse of the airway and periodic partial or complete upper airway obstruction. Anatomical optical coherence tomography (OCT) has the potential to provide high-speed three-dimensional tomographic images of the airway lumen without the use of ionizing radiation. In this chapter we describe the methods behind endoscopic OCT imaging and processing to generate full three dimensional anatomical models of the human airway which can be used in conjunction with numerical simulation methods to assess areas of airway obstruction. Combining this structural information with flow dynamic simulations, we can better estimate the site and causes of airway obstruction and better select and design surgery for patients with obstructive sleep apnea.

The opinion about the accuracy of the methods of upper quantiles estimation formed from the case of known population distribution function is upheld. The above-mentioned issue is the subject of the paper. The accuracy of large quantile assessments obtained from the four estimation methods is compared to two-parameter log-normal and log-Gumbel distributions and their three-parameter counterparts, i.e., three-parameter log-normal and GEV distributions. The cases of true and false hypothetical models are considered. The accuracy of flood quantile estimates depends on the sample size, the distribution type (both true and hypothetical, and strongly depends on the estimation method. In particular, the maximum likelihood method loses its advantageous properties in case of model misspecification.

  5. Neck muscle fatigue alters upper limb proprioception.

    2015-05-01

    Limb proprioception is an awareness by the central nervous system (CNS) of the location of a limb in three-dimensional space and is essential for movement and postural control. The CNS uses the position of the head and neck when interpreting the position of the upper limb, and altered input from neck muscles may affect the sensory inputs to the CNS and consequently may impair the awareness of upper limb joint position. The purpose of this study was to determine whether fatigue of the cervical extensors muscles (CEM) using a submaximal fatigue protocol alters the ability to recreate a previously presented elbow angle with the head in a neutral position. Twelve healthy individuals participated. CEM activity was examined bilaterally using surface electromyography, and kinematics of the elbow joint was measured. The fatigue protocol included an isometric neck extension task at 70 % of maximum until failure. Joint position error increased following fatigue, demonstrating a significant main effect of time (F 2, 18 = 19.41, p ≤ 0.0001) for absolute error. No significant differences were found for variable error (F 2, 18 = 0.27, p = 0.76) or constant error (F 2, 18 = 1.16 of time, p ≤ 0.33). This study confirms that fatigue of the CEM can reduce the accuracy of elbow joint position matching. This suggests that altered afferent input from the neck subsequent to fatigue may impair upper limb proprioception.

    The imaging features of extensive lipofibromatosis presenting in a 1-day-old female infant are reported. This lesion involved her entire right upper limb, extending from the axilla to the palm of the hand. Radiographs showed marked deformity and thinning of all the right upper-limb bones due to pressure effect of soft-tissue enlargement, especially affecting the distal humerus and proximal forearm bones. Magnetic resonance imaging showed a huge soft-tissue mass infiltrating most of the muscles of the entire upper limb, with bony erosion. The mass was largely T1-isointense, moderately T2-hyperintense and showed marked enhancement. There were intra-lesional signal changes consistent with fatty elements. A lesion debulking procedure was performed and the histology was that of lipofibromatosis. The limb was found to be non-viable after the procedure and a subsequent above-elbow amputation was performed. Although the resection margins were not clear, she had no further recurrence over a subsequent 3-year follow-up period. (orig.)

    Full Text Available Questions: Does constraint-induced movement therapy improve activity and participation in children with hemiplegic cerebral palsy? Does it improve activity and participation more than the same dose of upper limb therapy without restraint? Is the effect of constraint-induced movement therapy related to the duration of intervention or the age of the children? Design: Systematic review of randomised trials with meta-analysis. Participants: Children with hemiplegic cerebral palsy with any level of motor disability. Intervention: The experimental group received constraint-induced movement therapy (defined as restraint of the less affected upper limb during supervised activity practice of the more affected upper limb. The control group received no intervention, sham intervention, or the same dose of upper limb therapy. Outcome measures: Measures of upper limb activity and participation were used in the analysis. Results: Constraint-induced movement therapy was more effective than no/sham intervention in terms of upper limb activity (SMD 0.63, 95% CI 0.20 to 1.06 and participation (SMD 1.21, 95% CI 0.41 to 2.02. However, constraint-induced movement therapy was no better than the same dose of upper limb therapy without restraint either in terms of upper limb activity (SMD 0.05, 95% CI –0.21 to 0.32 or participation (SMD –0.02, 95% CI –0.34 to 0.31. The effect of constraint-induced movement therapy was not related to the duration of intervention or the age of the children. Conclusions: This review suggests that constraint-induced movement therapy is more effective than no intervention, but no more effective than the same dose of upper limb practice without restraint.

  11. Impact of obstructive apnea syndrome on upper airway respiratory muscles.

    Science.gov (United States)

    Svanborg, Eva

    2005-07-28

    This article reviews studies of upper airway muscles in humans, with emphasis on muscle fiber structural and electrophysiological changes observed in patients with obstructive sleep apnea syndrome (OSAS). The concept of OSAS as a progressive disease is discussed and also possible causes. These include local nervous lesions in the upper airway, both motor and sensory. Previous muscle biopsy studies have given evidence for motor neuron lesions such as, e.g., the phenomenon of type grouping in histological sections. New data obtained with concentric needle EMG recordings from the palatopharyngeus muscles are also presented. In 10/12 OSAS patients there were typical findings indicating motor neuropathy (reduced EMG activity at maximal voluntary effort, long and polyphasic motor-unit potentials and, in two cases, spontaneous denervation activity), whereas such findings were only present in 3/15 patients with habitual snoring. This supports the hypothesis that progression from habitual snoring to the clinical disease of OSAS could be attributed to peripheral neurogenic lesions.

    The diet of 25 invertebrate and fish species occurring in the upper Tagus estuary are compared. Multivariate methods are used to define trophic groups and identify key prey species, fundamental links in the understanding of the estuarine food web. Four trophic groups are described: microalgae, macroinfauna, mysid and fish and decapod eaters. It was found that the food web of this area heavily relies on the polychaete Nereis diversicolor and the crustacean Crangon crangon.

    Renal dysfunction is a common and serious problem in patients with advanced liver disease. The study aims to assess the incidence, risk factors and short-term prognosis of renal failure after upper-gastrointestinal bleeding among cirrhotic patients in Upper Egypt. We recruited 159 cirrhotic patients with 168 episodes of upper-gastrointestinal bleeding from Tropical Medicine and Gastroenterology Department, Assiut University Hospital. For all participants, the following were conducted: clinical evaluation, abdominal ultrasonography (US) examination, laboratory investigations and upper endoscopy. Risk factors of renal failure were identified using univariate, then multivariate analysis. The incidence of renal failure among bleeding episodes was 28%. Higher risk of renal failure among cirrhotic patients with upper-gastrointestinal bleeding was observed with shock (odds ratio (OR) 0.171, 95% confidence interval (CI) 0.047:0.624), bacterial infection (OR 0.310, 95% CI 107:897), Child-Pugh class C (OR 2.79, 95% CI 1.018:7.62), higher serum bilirubin (OR 0.122, 95% CI 0.000:0.002), lower serum albumin (OR -0.188, 95% CI -0.288:-0.056) and raised baseline blood urea (OR 0.181, 95% CI 0.003:0.017) and serum creatinine (OR 0.533, 95% CI 0.002:0.004). Mortality among patients with renal failure was 31.9%. Renal failure is a frequent event among cirrhotic patients with upper-gastrointestinal bleeding and there are many contributing factors for its development. Mortality is relatively high among patients with renal failure in cirrhotics with upper-gastrointestinal bleeding. Copyright © 2012 Arab Journal of Gastroenterology. Published by Elsevier Ltd.

    2016-01-01

    Pediatric upper gastrointestinal bleeding, a commonly seen pediatric emergency, needs timely symptomatic treatment to avoid a worse outcome. To discuss the clinical effect of thrombin treatment in combination with intensive nursing on pediatric upper gastrointestinal bleeding, this study analyzed 128 children who were treated in the second ward of the Children’s Internal Medical Department in the First Affiliated Hospital of Zhengzhou University between February 2012 and December 2014. The patients were divided into two groups, an experimental group and a control group. Besides thrombin, the experimental group was given intensive nursing, consisting of regular nursing and targeted nursing, while the control group was given regular nursing only. Clinical indexes of the two groups, such as effective rate, nursing satisfaction and side effect rate, were compared. Relevant clinical indexes such as duration of hospital stay, time to stopping of bleeding and Self-Rating Anxiety Scale (SAS) score, as well as overall satisfaction level of the observation group were all better than those of the control group and differences between the two groups had statistical significance (P less than 0.05). Furthermore, difference of overall effective rate between the experimental group (90.63%) and the control group (68.75%) was significant. Difference of incidence of side effects between the two groups was statistically significant. Thus thrombin treatment in combination with intensive nursing proved to have a remarkable clinical effect and high safety level in treating pediatric upper gastrointestinal bleeding and, moreover, it shortens treatment time and enhances the patients’ quality of life.

    2016-01-01

    INTRODUCTION: The associations between ABO blood group and cancer risk have been studied repeatedly, but results have been variable. Consistent associations have only been reported for pancreatic and gastric cancers. MATERIALS AND METHODS: We estimated associations between different ABO blood...... groups and site-specific cancer risk in a large cohort of healthy blood donors from Sweden and Denmark. RESULTS: A total of 1.6 million donors were followed over 27 million person-years (20 million in Sweden and 7 million in Denmark). We observed 119,584 cancer cases. Blood groups A, AB and B were...... associated either with increased or decreased risk of cancer at 13 anatomical sites (p≤0.05), compared to blood group O. Consistent with assessment using a false discovery rate approach, significant associations with ABO blood group were observed for cancer of the pancreas, breast, and upper gastrointestinal...

    Full Text Available This is a survey article on centralizers of finitesubgroups in locally finite, simple groups or LFS-groups as wewill call them. We mention some of the open problems aboutcentralizers of subgroups in LFS-groups and applications of theknown information about the centralizers of subgroups to thestructure of the locally finite group. We also prove thefollowing: Let $G$ be a countably infinite non-linear LFS-groupwith a Kegel sequence $mathcal{K}={(G_i,N_i | iinmathbf{N} }$. If there exists an upper bound for ${ |N_i| |iin mathbf{N} }$, then for any finite semisimplesubgroup $F$ in $G$ the subgroup $C_G(F$ has elements oforder $p_i$ for infinitely many distinct prime $p_i$. Inparticular $C_G(F$ is an infinite group. This answers Hartley'squestion provided that there exists a bound on ${ |N_i| | iin mathbf{N}$.

  12. BET 1: should tranexamic acid be given to patients who are having an upper gastrointestinal bleed?

    Science.gov (United States)

    Morgan, Anna; Jeffrey-Smith, Anna

    2012-09-01

    A short cut review was carried out to establish whether tranexamic acid should be given to patients having an upper gastrointestinal bleed. Seven studies and two systematic reviews were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that there is insufficient evidence, at the moment, to recommend the use of tranexamic acid in the management of upper gastrointestinal bleeding.

    1997-10-01

    The Upper Cretaceous sites of Laño and Quintanilla del Coco in northern Spain have yielded significant crocodilian remains, allowing a more precise interpretation of the fragmentary record of southwestern Europe. Two new genera, Musturzabalsuchus and Acynodon, have been recognized. Both taxa were extinct at the end of the Cretaceous. Their relationships with the alligatoroidean Eusuchia suggest a close relationship with Paleolaurasian groups. Musturzabalsuchus might be regarded as an endemic european taxa, the oldest known member of the basal Alligatoroidea. Acynodon is the only non-North American taxon that is related to the short snouted Upper Cretaceous alligatorids.

    Full Text Available Background and Objectives: Before the advent of endoscopy direct access to the lesion for the confirmation of the diagnosis was difficult, this posed difficulty in contemplating adequate and appropriate surgery. Endoscopy as a diagnostic and therapeutic tool has grown in recent years. Upper gastrointestinal (GI endoscopy is one of the most fascinating branch which serves not only as a means of resolving or amplifying the diagnosis made clinically or by X-ray, but also a primary diagnostic procedure for conditions not otherwise diagnosable on unoperated case. Fiber optic upper GI endoscopy has already become firmly established as a reliable, quick and inexpensive tool. This study was done to detect the upper gastrointestinal lesions in rural population of Kolar District, the distribution pattern of various upper GI lesions in patients presenting with upper GI symptoms and to follow the endoscopic diagnosis for medical and surgical management. Materials and Methods: The study group includes patients reporting to outpatient department and also the inpatients in wards of General Surgery and other departments, who have upper GI symptoms, were advised endoscopy at R. L. JALAPPA Hospital and Research Centre, Kolar, from a period of December 2011 to August 2013. Results: Of the 600 cases, 370 were males, and 230 were females. Disease incidence was highest in 51-70 years age group, that is, 21.6%. Pain abdomen was the most common symptom. Epigastric tenderness was the most common sign among the patients clinically. Reflux esophagitis and diffuse gastritis formed most common cases (307 cases. The incidence of duodenitis - 7.83%, peptic ulcer -3.3%, esophageal varices - 1.5%, the incidence of carcinoma esophagus and carcinoma stomach was approximately same that is, 4.5% and 4.6% respectively. The incidence of esophageal candidiasis was 4.16%. The majority of the patients had a normal study that is, 14.5%. Conclusion: Upper GI lesions were more common in

    Full Text Available Aim: to review the effectiveness of tranexamic acid therapy which has been proposed to reduce bleeding and in turn lower mortality rate. Methods: following literature searching based on our clinical question on Cochrane Library, PubMed, Clinical Key, EBSCO, Science Direct and Proquest, one systematic review that includes seven randomized controlled trials is obtained. The article meets validity and relevance criteria. Results: the systematic review found that there is no any clear evidence between intervention and control groups in term of mortality. Conclusion: the use of tranexamic acid to reduce mortality in patients with upper gastrointestinal bleeding is not recommended. Key words: tranexamic acid, mortality, upper gastrointestinal bleeding.

    Full Text Available This is an introduction to finite simple groups, in particular sporadic groups, intended for physicists. After a short review of group theory, we enumerate the 1+1+16=18 families of finite simple groups, as an introduction to the sporadic groups. These are described next, in three levels of increasing complexity, plus the six isolated ''pariah'' groups. The (old five Mathieu groups make up the first, smallest order level. The seven groups related to the Leech lattice, including the three Conway groups, constitute the second level. The third and highest level contains the Monster group M, plus seven other related groups. Next a brief mention is made of the remaining six pariah groups, thus completing the 5+7+8+6=26 sporadic groups. The review ends up with a brief discussion of a few of physical applications of finite groups in physics, including a couple of recent examples which use sporadic groups.

    To evaluate the effect of extracorporeal shock wave therapy (ESWT) in myofascial pain syndrome of upper trapezius with visual analogue scale (VAS) and pressure threshold by digital algometer. Twenty-two patients diagnosed with myofascial pain syndrome in upper trapezius were selected. They were assigned to treatment and standard care (control) groups balanced by age and sex, with eleven subjects in each group. The treated group had done four sessions of ESWT (0.056 mJ/mm(2), 1,000 impulses, semiweekly) while the control group was treated by the same protocol but with different energy levels applied, 0.001 mJ/mm(2). The VAS and pressure threshold were measured twice: before and after last therapy. We evaluated VAS of patients and measured the pressure threshold by using algometer. There were two withdrawals and the remaining 20 patients were three men and 17 women. Age was distributed with 11 patients in their twenties and 9 over 30 years old. There was no significant difference of age, sex, pre-VAS and pre-pressure threshold between 2 groups (p>0.05) found. The VAS significantly decreased from 4.91±1.76 to 2.27±1.27 in the treated group (pmyofascial pain syndrome of upper trapezius is effective to relieve pain after four times therapies in two weeks. But further study will be required with more patients, a broader age range and more males.

    Transarterial embolization (TAE) is a therapeutic option for patients with a high risk of recurrent bleeding after endoscopic haemostasis. The aim of our prospective study was a preliminary assessment of the safety, efficacy, and clinical outcomes following preventive TAE in patients with non-variceal acute upper gastrointestinal bleeding (NVUGIB) with a high risk of recurrent bleeding after endoscopic haemostasis. Preventive visceral angiography and TAE were performed after endoscopic haemostasis on patients with NVUGIB who were at a high risk of recurrent bleeding (PE+ group). The comparison group consisted of similar patients who only underwent endoscopic haemostasis, without preventive TAE (PE- group). The technical success of preventive TAE, the completeness of haemostasis, the incidence of rebleeding and the need for surgical intervention and the main outcomes were compared between the groups. The PE+ group consisted of 25 patients, and the PE- group of 50 patients, similar in age (median age 66 vs. 63 years), gender and comorbid conditions. The ulcer size at endoscopy was not significantly different (median of 152 mm vs. 127 mm). The most frequent were Forest II type ulcers, 44% in both groups. The distribution of the Forest grade was even. The median haemoglobin on admission was 8, 2 g/dl vs. 8,7 g/dl, p = 0,482, erythrocyte count was 2,7 × 10(12)/L vs. 2,9 × 10(12)/L, p = 0,727. The shock index and Rockall scores were similar, as well as and transfusion - on average, four units of packed red blood cells for the majority of patients in both groups, however, significantly more fresh frozen plasma was transfused in the PE- group, p = 0,013. The rebleeding rate was similar, while surgical treatment was needed notably more often in the PE- group, 8% vs. 35% accordingly, p = 0,012. The median ICU stay was 3 days, hospital stay - 6 days vs. 9 days, p = 0.079. The overall mortality reached 20%; in the PE+ group it was 4%, not

    2017-01-01

    We present the analysis of student networks derived from a survey of upper division physics students. Ego networks focus on the connections that center on one person (the ego). The ego networks in this talk come from a survey that is part of an overall project focused on understanding student retention and persistence. The theory underlying this work is that social and academic integration are essential components to supporting students continued enrollment and ultimately graduation. This work uses network analysis as a way to investigate the role of social and academic interactions in retention and persistence decisions. We focus on student interactions with peers, on mentoring interactions with physics department faculty, and on engagement in physics groups and how they influence persistence. Our results, which are preliminary, will help frame the ongoing research project and identify ways in which departments can support students. This work supported by NSF grant #PHY 1344247.

    Hensing, John A

    2008-01-01

    In 2001, executives at Banner Health (a large hospital system with corporate offices based in Phoenix, AZ) proactively responded to external forces, emphasizing improvement in the quality and safety of patient care in hospitals. Organized under the umbrella of care management, 11 functional teams, ranging from process improvement and patient safety to clinical innovation and population health management, were created to achieve this goal. Initially focused on improvement with core measure metrics, these teams and their related work groups (focused on more task-specific work) initiated their plan in 20 facilities in seven states and supported local implementation of recommended changes that were grounded in evidence-based medicine. With 2 years of experience with this process, Banner Health began a 3-year journey from 2004 to 2006 to reach upper-quartile performance in select clinical quality metrics. A retrospective account of the experience follows.

  1. STRONTIUM DISTRIBUTION IN UPPER DEVONIAN CONODONT ELEMENTS: A PALAEOBIOLOGICAL PROXY

    Directory of Open Access Journals (Sweden)

    ANDREY V. ZHURAVLEV

    2017-04-01

    Full Text Available Conodonts are an extinct group of marine animals possessing debated affinities. The conodont elements are composed of calcium phosphate [apatite (CaF] and collagen-like proteins. Distribution of Sr in the bioapatite of albid, lamellar and paralamellar tissues of some Upper Devonian conodont element crowns from NW Russia was studied by microprobe. The calcium phosphate of the lamellar and paralamellar tissues demonstrates periodical oscillation of Sr contents across the lamellae (0.4-0.5 wt% in the outer part of lamella, and 0.2 wt% in the inner part. The albid tissue contains Sr of less than 0.4 wt%. It is suggested that oscillations of Sr concentrations reflect the periodic growth of the lamellae, and the average Ca/Sr ratio can be a proxy of the growth rate.

  2. Intrauterine device and upper-genital-tract infection.

    2000-09-16

    Concern about upper-genital-tract infection related to intrauterine devices (IUDs) limits their wider use. In this systematic review I summarise the evidence concerning IUD-associated infection and infertility. Choice of an inappropriate comparison group, overdiagnosis of salpingitis in IUD users, and inability to control for the confounding effects of sexual behaviour have exaggerated the apparent risk. Women with symptomless gonorrhoea or chlamydial infection having an IUD inserted have a higher risk of salpingitis than do uninfected women having an IUD inserted; however, the risk appears similar to that of infected women not having an IUD inserted. A cohort study of HIV-positive women using a copper IUD suggests that there is no significant increase in the risk of complications or viral shedding. Similarly, fair evidence indicates no important effect of IUD use on tubal infertility. Contemporary IUDs rival tubal sterilisation in efficacy and are much safer than previously thought.

    We compared outcome variables (operative complications, inflammatory complications, and operating time) in patients being treated by orthodontic extraction of upper premolars with the Physics forceps or the universal extraction forceps. We organised a single blind, split-mouth clinical trial to compare the outcomes of the 2 groups (n=54 premolars). The Physics forceps group had lower mean (SD) visual analogue scores (VAS) for pain (0.59 (0.57)) on the first postoperative day than the other group (1.04 (0.85)) (p=0.03). There were no other significant differences between the 2 groups in any other variable studied.

    [Purpose] This study investigated upper-extremity muscle activities in natural, ideal, and corrected head positions. [Subjects and Methods] Forty subjects with a forward head posture and rounded shoulder were recruited and randomly assigned to the natural head position group (n = 13), ideal head position group (n = 14), or corrected head position group (n = 13). Muscle activities were measured using a four-channel surface electromyography system at the sternocleidomastoideus, upper and lower trapezius, and serratus anterior muscles on the right side during an overhead reaching task. [Results] The muscle activities of the upper trapezius and serratus anterior differed significantly among head positions. Post hoc tests revealed significant differences between natural and ideal head positions, and natural and ideal head positions for both the upper trapezius and serratus anterior. [Conclusion] Recovery of normal upper trapezius and serratus anterior muscle functions plays an important role in correcting forward head posture and rounded shoulders.

    Full Text Available The paper describes results of the studies devoted to the solar activity impact on the Earth’s upper atmosphere and ionosphere, conducted within the frame of COST ES0803 Action. Aim: The aim of the paper is to represent results coming from different research groups in a unified form, aligning their specific topics into the general context of the subject. Methods: The methods used in the paper are based on data-driven analysis. Specific databases are used for spectrum analysis, empirical modeling, electron density profile reconstruction, and forecasting techniques. Results: Results are grouped in three sections: Medium- and long-term ionospheric response to the changes in solar and geomagnetic activity, storm-time ionospheric response to the solar and geomagnetic forcing, and modeling and forecasting techniques. Section 1 contains five subsections with results on 27-day response of low-latitude ionosphere to solar extreme-ultraviolet (EUV radiation, response to the recurrent geomagnetic storms, long-term trends in the upper atmosphere, latitudinal dependence of total electron content on EUV changes, and statistical analysis of ionospheric behavior during prolonged period of solar activity. Section 2 contains a study of ionospheric variations induced by recurrent CIR-driven storm, a case-study of polar cap absorption due to an intense CME, and a statistical study of geographic distribution of so-called E-layer dominated ionosphere. Section 3 comprises empirical models for describing and forecasting TEC, the F-layer critical frequency foF2, and the height of maximum plasma density. A study evaluates the usefulness of effective sunspot number in specifying the ionosphere state. An original method is presented, which retrieves the basic thermospheric parameters from ionospheric sounding data.

    Purpose Pedicle screw fixation in the upper cervical spine is a difficult and high-risk procedure. The screw is difficult to place rapidly and accurately, and can lead to serious injury of spinal cord or vertebral artery. The aim of this study was to design an individualized 3D printing navigation template for pedicle screw fixation in the upper cervical spine. Methods Using CT thin slices data, we employed computer software to design the navigation template for pedicle screw fixation in the upper cervical spine (atlas and axis). The upper cervical spine models and navigation templates were produced by 3D printer with equal proportion, two sets for each case. In one set (Test group), pedicle screws fixation were guided by the navigation template; in the second set (Control group), the screws were fixed under fluoroscopy. According to the degree of pedicle cortex perforation and whether the screw needed to be refitted, the fixation effects were divided into 3 types: Type I, screw is fully located within the vertebral pedicle; Type II, degree of pedicle cortex perforation is 1 mm or with the poor internal fixation stability and in need of renovation. Type I and Type II were acceptable placements; Type III placements were unacceptable. Results A total of 19 upper cervical spine and 19 navigation templates were printed, and 37 pedicle screws were fixed in each group. Type I screw-placements in the test group totaled 32; Type II totaled 3; and Type III totaled 2; with an acceptable rate of 94.60%. Type I screw placements in the control group totaled 23; Type II totaled 3; and Type III totaled 11, with an acceptable rate of 70.27%. The acceptability rate in test group was higher than the rate in control group. The operation time and fluoroscopic frequency for each screw were decreased, compared with control group. Conclusion The individualized 3D printing navigation template for pedicle screw fixation is easy and safe, with a high success rate in the upper cervical spine

    The aim of this study was to compare the effects of erythromycin infusion and gastric lavage in order to improve the quality of visualization during emergency upper endoscopy. We performed a prospective randomized pilot study. Patients presented with hematemesis or melena within 12 hours and were randomly assigned to the erythromycin group (intravenous infusion of erythromycin), gastric lavage group (nasogastric tube placement with gastric lavage), or erythromycin + gastric lavage group (both erythromycin infusion and gastric lavage). The primary outcome was satisfactory visualization. Secondary outcomes included identification of a bleeding source, the success rate of hemostasis, duration of endoscopy, complications related to erythromycin infusion or gastric lavage, number of transfused blood units, rebleeding rate, and bleeding-related mortality. A total of 43 patients were randomly assigned: 14 patients in the erythromycin group; 15 patients in the gastric lavage group; and 14 patients in the erythromycin + gastric lavage group. Overall satisfactory visualization was achieved in 81% of patients: 92.8% in the erythromycin group; 60.0% in the gastric lavage group; and 92.9% in the erythromycin + gastric lavage group, respectively (p = 0.055). The identification of a bleeding source was possible in all cases. The success rate of hemostasis, duration of endoscopy, and number of transfused blood units did not significantly differ between groups. There were no complications. Rebleeding occurred in three patients (7.0%). Bleeding-related mortality was not reported. Intravenous erythromycin infusion prior to emergency endoscopy for acute nonvariceal upper gastrointestinal bleeding seems to provide satisfactory endoscopic visualization.

    Full Text Available Aim: We aimed to compare the success rate of the use of a pneumatic and a holmium laser lithotripter for endoscopic treatment of upper ureteral calculi with semirigid uretero-renoscopy (URS. Material and Method: A total of 74 patients were included in this study. The patients were divided into two groups; a ballistic lithotripter was used for group 1 containing 33 and a Holmium-YAG laser lithotripter for the remaining 41 patients in group 2. Both groups were compared in terms of stone size the duration of the operation, postoperative hospitalization time, stone-free rate and complications. Results: The mean age of the patients was 47.6. The mean stone size in groups 1 and 2 were 16.4mm and 11.0mm, respectively (p=0.043. The mean stone-free rate groups 1 and 2 were 78.7% and 80.5% respectively at the approximately 1 month follow-up (p=0.391. In group 1 two patients and in group 2 two patients had a minor complication (ClavienI-II. In group 1 three patients had major complications due to ureteral perforation (Clavien 3a and 3b. No major complications (Clavien III-V occurred in Group 2. Discussion: Based on these findings laser lithotripsy can be regarded as safer. If laser lithotripter is available in medical centers, we argue that it should be the first choice for the treatment of upper ureteral stones.

    Warfarin is a widely used and easily reversible anticoagulant. Although bleeding is more likely in warfarin users, it may also be more readily treated. This retrospective observational case-control study compares the outcome of acute nonvariceal upper gastrointestinal hemorrhage in warfarin users with a supratherapeutic international normalized ratio (INR) and outcome in non - warfarin users. Clinical and endoscopic data for patients presenting with overt upper gastrointestinal hemorrhage were collected between 23rd February 2001 and 12 October 2010. Patients with variceal hemorrhage were excluded. Warfarin users with a supratherapeutic INR (≥ 3.0) at presentation (supratherapeutic anticoagulation [SA] group) were matched to a cohort with upper gastrointestinal hemorrhage not taking warfarin at presentation (control group). Patients were matched by age, sex, Rockall score, year of endoscopy, inpatient or outpatient status, and the presence of disseminated cancer at presentation. The incidence rates of major outcomes in the two groups were compared. A total of 128 patients (SA group) were matched to 135 control patients. The SA group patients were less likely to die within 30 days (6.25 % vs. 15.5 %, odds ratio = 0.36, P = 0.028 by Test for Equality of Proportions). There was a trend toward more surgery in the control group (5 % vs. 2 %), and rates of blood transfusion (77 % vs. 70 %) were similar in the two groups. In patients presenting with nonvariceal upper gastrointestinal hemorrhage, a supratherapeutic INR at presentation due to warfarin use is associated with reduced mortality.

    Thoracic sympathectomy is performed in the management of a variety of disorders of the upper extremity. To evaluate the contemporary results of thoracic sympathectomy for upper extremity ischemia a systematic review of the literature was conducted. We performed a PubMed, EMBASE and Cochrane search of the literature written in the English language from January 1975 to December 2015. All articles presenting original patient data regarding the effect of treatment on symptoms or on the healing of ulcers were eligible for inclusion. Individual analyses for Primary Raynaud's Disease (PRD) and Secondary Raynaud's Phenomenon (SRP) were performed. We included 6 prospective and 23 retrospective series with a total of 753 patients and 1026 affected limbs. Early beneficial effects of thoracic sympathectomy were noticed in 63-100% (median 94%) of all patients, in 73-100% (median 98%) of PRD patients and in 63-100% (median 94%) of SRP patients. The beneficial effect was noted to lessen over time. Long-term beneficial effects were reported in 13-100% (median 75%) of all patients, in 22-100% (median 58%) of PRD patients, and in 13-100% (median 79%) of SRD patients. Complete or improved ulcer healing was achieved in 33-100% and 25-67% respectively, of all patients. Thoracic sympathectomy can be beneficial in the treatment of upper extremity ischemia in select patients. Although the effect in patients with PRD will lessen over time, it may still reduce the severity of symptoms. In SRD, effects are more often long-lasting. In addition, thoracic sympathectomy may maximize tissue preservation or prevent amputation in cases of digital ulceration.

    Despite their rising popularity, the health care profession has been slow to embrace social networking sites. These are Web-based initiatives, designed to bring people with common interests or activities under a common umbrella. The purpose of this study is to evaluate social networking patterns among upper extremity patients. A total of 742 anonymous questionnaires were distributed among upper extremity outpatients, with a 62% response rate (462 were completed). Demographic characteristics (gender, age, level of education, employment, type of health insurance, and income stratification) were defined, and data on computer ownership and frequency of social networking use were collected. Social network users and nonusers were compared according to their demographic and socioeconomic characteristics. Our patient cohort consisted of 450 patients. Of those 450 patients, 418 had a high school education or higher, and 293 reported a college or graduate degree. The majority of patients (282) were employed at the time of the survey, and income was evenly distributed among U.S. Census Bureau quintiles. A total of 349 patients reported computer ownership, and 170 reported using social networking sites. When compared to nonusers, social networking users were younger (pnetworking use. Most users (n = 114) regularly visit a single site. Facebook was the most popular site visited (n=142), followed by MySpace (n=28) and Twitter (n=16). Of the 450 upper extremity patients in our sample, 170 use social networking sites. Younger age, higher level of education, and computer ownership were associated with social networking use. Physicians should consider expanding their use of social networking sites to reach their online patient populations. Copyright 2010 American Society for Surgery of the Hand.

  14. Upper and lower bounds on quantum codes

    Science.gov (United States)

    Smith, Graeme Stewart Baird

    This thesis provides bounds on the performance of quantum error correcting codes when used for quantum communication and quantum key distribution. The first two chapters provide a bare-bones introduction to classical and quantum error correcting codes, respectively. The next four chapters present achievable rates for quantum codes in various scenarios. The final chapter is dedicated to an upper bound on the quantum channel capacity. Chapter 3 studies coding for adversarial noise using quantum list codes, showing there exist quantum codes with high rates and short lists. These can be used, together with a very short secret key, to communicate with high fidelity at noise levels for which perfect fidelity is, impossible. Chapter 4 explores the performance of a family of degenerate codes when used to communicate over Pauli channels, showing they can be used to communicate over almost any Pauli channel at rates that are impossible for a nondegenerate code and that exceed those of previously known degenerate codes. By studying the scaling of the optimal block length as a function of the channel's parameters, we develop a heuristic for designing even better codes. Chapter 5 describes an equivalence between a family of noisy preprocessing protocols for quantum key distribution and entanglement distillation protocols whose target state belongs to a class of private states called "twisted states." In Chapter 6, the codes of Chapter 4 are combined with the protocols of Chapter 5 to provide higher key rates for one-way quantum key distribution than were previously thought possible. Finally, Chapter 7 presents a new upper bound on the quantum channel capacity that is both additive and convex, and which can be interpreted as the capacity of the channel for communication given access to side channels from a class of zero capacity "cloning" channels. This "clone assisted capacity" is equal to the unassisted capacity for channels that are degradable, which we use to find new upper

    The department of internal medicine of the military hospital of Gabon managed 92 cases of upper gastrointestinal bleeding from April 2009 to November 2011. The frequency of these hemorrhages in the department was 8.2%; they occurred most often in adults aged 30-40 years and 50-60 years, and mainly men (74%). Erosive-ulcerative lesions (65.2%) were the leading causes of hemorrhage, followed by esophageal varices (15.2%). These results underline the importance of preventive measures for the control of this bleeding.

    We take a new approach to obtaining necessary and sufficient conditions for the incompleteness of exponential polynomials in Lp/α, where Lp/α is the weighted Banach space of complex continuous functions f defined on the real axis (R)satisfying (∫+∞/-∞|f(t)|pe-α(t)dt)1/p, 1 < p < ∞, and α(t) is a nonnegative continuous function defined on the real axis (R). In this paper, the upper density of the sequence which forms the exponential polynomials is not required to be finite. In the study of weighted polynomial approximation, consideration of the case is new.

    2010-01-01

    The effects of a nonzero photon rest mass can be incorporated into electromagnetism in a simple way using the Proca equations. In this vein, two interesting implications regarding the possible existence of a massive photon in nature, i.e., tiny alterations in the known values of both the anomalous magnetic moment of the electron and the gravitational deflection of electromagnetic radiation, are utilized to set upper limits on its mass. The bounds obtained are not as stringent as those recently found; nonetheless, they are comparable to other existing bounds and bring new elements to the issue of restricting the photon mass.

    Studies in the past decade have shown that a significant proportion of instrumentalists report musculoskeletal problems severely affecting their musical performance. Musicians endure daily intensive use of their upper extremities, frequently placing them in bizarre positions. Their training schedules are rigorous and long term Predisposing factors to, and treatment for, overuse syndromes, tendinitis, and tendon trauma commonly encountered by musical performers are discussed at length. Nerve entrapment has also surfaced as a major problem in musicians, and the means of evaluation and treatment and the role of surgery are put forth. Techniques for studying and analyzing the difficulties faced by instrumentalists are summarized.

    Full Text Available The concept of “responsible tourism”, which has spread rapidly in recent years, evokes conscious tourist behavior so as to minimize negative impacts on destinations, from an environmental, economic and cultural point of view. While intuitively comprehensible, the concept is not easy to operationalize in empirical studies. Facing this difficulty, our contribution illustrates an attempt to operatively define the concept within the framework of the development of a sustainable destination plan for the Ancient Cities of Upper Myanmar (ACUM. The paper describes the index adopted to survey and measure responsible attitudes among tourists and the main results of the research.

    Full Text Available Paralysis causes loss of muscle function and loss of feeling in the affected area. The main problem faced by the patients after paralysis is muscle atrophy caused due to non-functionality of the stump. Orthotics is an orthopedic device which supports the function of the arm, leg or torso. This paper deals with the design of an upper limb orthotic device which has a hollow shell/ braces structure and can be used by paralyzed patients to bring about simple hand movements independently by the patient.

    The aims of this study were to develop and evaluate reliability of a quantitative assessment tool for upper limb sense of position on the horizontal plane. We evaluated 15 healthy individuals (controls) and 9 stroke patients. A robotic device passively moved one arm of the blindfolded participant who had to actively move his/her opposite hand to the mirror location in the workspace. Upper-limb's position was evaluated by a digital camera. The position of the passive hand was compared with the active hand's 'mirror' position. Performance metrics were then computed to measure the mean absolute errors, error variability, spatial contraction/expansion, and systematic shifts. No significant differences were observed between dominant and non-dominant active arms of controls. All performance parameters of the post-stroke group differed significantly from those of controls. This tool can provide a quantitative measure of upper limb sense of position, therefore allowing detection of changes due to rehabilitation.

    Duodenogastric reflux, the reflux of duodenal bile into stomach, when suspected clinically requires an objective evaluation for proper management. In this study hepatobiliary scintigraphy in 91 patients of different clinical conditions was evaluated for presence of duodenogastric reflux. Upper gastrointestinal endoscopy was also performed in 44 of these patients. On scintigraphy duodenogastric reflux was present in 26 (29%) of 91 patients. Upper gastrointestinal endoscopy revealed presence of refluxed bile in the stomach in 12 (27%) of 44 patients. In the same groups of patients scintigraphy detected reflux in 18 (41%) of 44 patients. This shows that hepatobiliary scintigraphy is superior to upper gastrointestinal endoscopy in detection of duodenogastric reflux and also has the advantage of being non-invasive and physiological.

    To measure the upper-airway resistance in patients with tracheostomies and determine the value representing decannulation readiness. Fifty-six patients with tracheostomies resultant to laryngeal disease participated in this study. Forty patients met clinical criteria for decannulation; 16 did not. Subglottal pressure was measured with a tube connected to the tracheostomy tube, and airflow was monitored simultaneously using a facemask. Upper-airway resistance measurements were recorded during shallow and deep breathing. During both shallow and deep breathing, the inspiratory and expiratory resistances were significantly higher for the group unsuitable for decannulation (P resistance measures for diagnosis. Objective measurement of upper-airway resistance during shallow and deep breathing may be a useful parameter in determining decannulation readiness of tracheostomized patients.

    Background: Upper arm composition is a reflection of body protein and calorie reserves. However, there is a paucity of data on upper arm composition of children from African countries, including Nigeria. This study aimed to determine the composition of upper arm and nutritional status of school children in Abeokuta, Nigeria and to compare with international reference standards. The sensitivity and specifi city of upper arm muscle area by height (UAMAH) as a nutritional assessment tool was also determined. Methods: Five hundred and seventy children aged 5 to 19 years were selected from seven schools using multistage random sampling. Weight, height, mid-upper arm circumference (MUAC) and triceps skin fold thickness (TSF) were measured. Body mass index, upper arm muscle area (UAMA), upper arm fat area (UAFA), fat percentage and UAMAH were derived. Results: The TSF, UAFA and fat percentage were significantly higher in females than males at each age group. MUAC and UAMA were significantly higher in female children aged 10-14 years, whereas UAMA was significantly higher in male children aged 15-19 years. UAMA and UAFA of the children were lower than those of Americans but similar to those of Zimbabweans, and higher than those of Indians. The sensitivity and specifi city of UAMAH for detecting wasting were 80.8% and 63.9%, respectively, whereas the corresponding values for stunting were 32.2% and 58.2%, respectively. Conclusions: The school children studied have a combination of poor calorie and protein reserve. UAMAH may be a valuable tool for complete evaluation of the nutritional status of school children.

    Upper endoscopy can be successfully carried out in children under deep sedation and anaesthesia. However, the best method of upper endoscopy for children who require gastrointestinal intervention has yet to be defined. The aim of this study is to investigate the efficacy and safety of the sedation induced by intravenous midazolam and ketamine during upper endoscopy in children. This study included patients ages 3-18years who had undergone upper endoscopy. All subjects received IV midazolam and ketamine. During the intervention, hypoxia, tachycardia, bradycardia, hypertension, and hypotension were recorded. After the intervention, euphoria, dysphoria, vertigo, visual problems (such as diplopia and nystagmus), and emergencies (such as arrhythmia, convulsion, and hallucination), among other findings, were recorded. Older children who were capable of expressing themselves were questioned to help determine these conditions. The mean age of the study group was was 11.9±3.42years; 54% of the patients were females, and 46% were males. During the upper endoscopy, hypoxia occurred in 9% of patients, mild hypertension in 14%, hypotension in 5%, tachycardia in 23%, bradycardia in 8%, and flushing-urticaria in 2%. After the upper endoscopy, one of the most common complications was sore throat, which occurred in 24% of patients. Vomiting was observed in 14% of patients, dizziness in 24%, diplopia in 27%, euphoria in 3% (5 patients), dysphoria in 4%, and hallucination in 4%. Of the total patients, 4% required oxygen supply with a face mask. The results of our study showed that the use of IV midazolam and ketamine during upper endoscopy in children was safe and effective.

    The purpose of this study is to present controversial point and reform measurements by analysing factors having important effect on selection of upper gastrointestinal study in total health promotion. We examined 200 persons for this study, who visited for upper gastrointestinal study from January to February in 1999. We classified this group into Endoscopy, Upper gastrointestinal series, and sleeping endoscopy. We also investigated standard of satisfaction and factors having effect on selection of each study. As is results, in the motive of selection, Item of 'making accurate observation' and 'without pain' was 39.3% and 34.7%, respectively. In this study, sleeping endoscopy was 45.7%, but on the other side upper gastrointestinal series was low 22.6%(P<0.05). In the standard of preference of study, the man was 55.7% in the endoscopy, and the woman was 61.8% in the upper gastrointestinal series(P<0.05). The standard of preference of upper gastrointestinal series show that it was satisfied on the whole irrespective of sex, dwelling place, age, occupation, and level of education. In the selection of study, one's own will was showed the highest frequency, and family inducement was showed second(P<0.05). Persons over 60% were examined before the same study. Selection of upper gastrointestinal series was 47.9% of person with normal findings, and endoscopy and sleeping endoscopy was over 70% with gastritis, gastric and duodenal(P<0.01). For one's accurate selection of examination, it is important that objective and credible information should be given to a recipient for examination.

    To investigate the effect of previous incisional double-fold surgery on spontaneous resolution of eyelid retraction caused by Graves orbitopathy (GO) in Asian individuals. Retrospective review of medical records. Patients (N = 30; 39 eyes) with eyelid retraction associated with GO with symptom duration of less than 6 months. Patients who visited the Ophthalmology Department of Severance Hospital, Yonsei University, between January 2010 and December 2011, followed up for more than 6 months and in a euthyroid state with antithyroid drug treatment were included. Patients treated with steroids or who underwent surgery during follow-up were excluded. Upper scleral show was measured as the distance between the central upper lid margin and limbus at initial presentation and after 6 months. Comparative analysis was performed between the 2 groups delineated by history (n = 12; 16 eyes), or lack thereof (n = 18; 23 eyes), of incisional double-fold surgery before onset of GO symptoms and signs. Patient demographics and initial upper scleral show were not significantly different between groups. In both groups, upper scleral show significantly decreased at 6 months of follow-up (p < 0.001 in both groups); however, improvement of upper scleral show was significantly reduced in patients who had undergone previous double-fold surgery (0.8 ± 0.5 mm) than in nonsurgical patients (1.8 ± 0.5 mm; p < 0.001). Graves eyelid retraction resolves spontaneously over time, albeit not completely. Previous double-fold surgery hinders the degree of spontaneous resolution, probably because of the fibrosis and cicatrization between the skin, the subcutaneous layer, and the levator complex.

    Full Text Available Background: Hemiplegia is the commonest form of paralysis, involving arm, leg and sometimes the face on one side of the body. Shoulder girdle in chronic hemiplegic suffers from two sorts of problems (a spasticity of elevators and retractors, which pull the scapula into a fixed elevated and retracted position. (b weakness of the opposite group of scapular muscles, i.e., depressors and protectors. This leads to instability of the scapulothoracic joint resulting in impaired functional use of the upper limb, taping is a method of maintaining orientation of the scapula by means of proprioceptive biofeedback to the patient. Aim of this study is to check the effect of taping on scapular stability and upper limb function in recovering hemiplegics. Objectives of the Study: (1 To study the effect of taping on functional performance of the hemiplegic upper extremity. (2 To compare the effect of taping combined with physiotherapeutic exercises v/s physiotherapeutic exercises alone on functional independence of the hemiplegic upper extremity. Subjects: All the 37 chronic hemiplegic patients with scapular weakness were taken and divided into two groups: Group A (Experimental group and Group B (Control group. Materials and Methods: All the 37 chronic hemiplegic patients were evaluated by Fugl Meyer Physical Performance Assessment Scale for hemiplegic upper extremity before starting the treatment. Group A patients received scapular taping combined with physiotherapeutic exercises and Group B patients received only physiotherapeutic exercises for the period of 2 weeks. After 2 weeks both Group A and B patients were re-evaluated on Fugl Meyer Physical Performance Assessment Scale for hemiplegic upper extremity. Results: There was a significant improvement between the pre- and post-treatment scores of Group A patients on the Fugl Meyer Physical Performance Assessment Scale of hemiplegic upper extremity, whereas Group B patients score on the same scale was

    El Zaatari, Sireen; Hublin, Jean-Jacques

    2014-04-01

    This article presents the results of the occlusal molar microwear texture analysis of 32 adult Upper Paleolithic modern humans from a total of 21 European sites dating to marine isotope stages 3 and 2. The occlusal molar microwear textures of these specimens were analyzed with the aim of examining the effects of the climatic, as well as the cultural, changes on the diets of the Upper Paleolithic modern humans. The results of this analysis do not reveal any environmentally driven dietary shifts for the Upper Paleolithic hominins indicating that the climatic and their associated paleoecological changes did not force these humans to significantly alter their diets in order to survive. However, the microwear texture analysis does detect culturally related changes in the Upper Paleolithic humans' diets. Specifically, significant differences in diet were found between the earlier Upper Paleolithic individuals, i.e., those belonging to the Aurignacian and Gravettian contexts, and the later Magdalenian ones, such that the diet of the latter group was more varied and included more abrasive foods compared with those of the former.

    Wu, Tzong-Ming; Chen, Dar-Zen

    2012-06-01

    Resistance training is a popular form of exercise recommended by national health organizations, such as the American College of Sports Medicine (ACSM) and the American Heart Association (AHA). This form of training is available for most populations. A compact design of upper limb exoskeleton mechanism for homebased resistance training using a spring-loaded upper limb exoskeleton with a three degree-of-freedom shoulder joint and a one degree-of-freedom elbow joint allows a patient or a healthy individual to move the upper limb with multiple joints in different planes. It can continuously increase the resistance by adjusting the spring length to train additional muscle groups and reduce the number of potential injuries to upper limb joints caused by the mass moment of inertia of the training equipment. The aim of this research is to perform a preliminary evaluation of the designed function by adopting an appropriate motion analysis system and experimental design to verify our prototype of the exoskeleton and determine the optimal configuration of the spring-loaded upper limb exoskeleton.

    Full Text Available PURPOSE: to evaluate the position of the upper eyelid margin and eye surface status in cicatricial trachoma without trichiasis (TS. METHODS: Slit-lamp biomicroscopy was employed to evaluate the location of the upper lid mucocutaneous transition of 156 eyes of 78 patients with trichiasis and of 130 eyes of 65 control subjects. For each eye the position of the upper lid mucocutaneous junction was graded with respect to the line of meibomian gland orifices into 3 categories: a anterior, b at the line, and c posterior to the line. Ocular surface dye staining with lissamine green was performed in all eyes. All participants answered a questionnaire with queries on the presence and intensity of dry eye symptoms. RESULTS: In the eyes with trichiasis the location of the mucocutaneous transition was posterior to the meibomian gland line in 55 (35.3%, at the line in 77 (49.4% and anterior to the line in only 24 (15.4%. In the control group these figures were: 5 (3.8%; 42 (42% and 83 (63.8%. Lissamine staining and dry eye symptoms were also associated with trichiasis. CONCLUSION: Different degrees of upper lid entropion are already present in cicatricial trachoma even in the absence of trichiasis. Trichiasis is associated with lissamine green staining and dry eye symptoms. Conjunctivalization of the upper lid margin may play a role in the development of trachomatous dry eye.

The variant of surgical treatment and it's results are depend on the cause of upper extremity deformation. Materials and methods. This study is based on a survey of children with cerebral palsy with lesions of the upper extremity. The main criterion for the selection of patients was the presence of the combined lesion of the upper extremity, where the cause of dysfunction hands are not only fixed contractures, but primary tonic. Was to survey 47 patients with spastic forms of cerebral palsy with the defeat of the upper limb, but the study group included only 26 of them in the ages of 7 to 18 years (average 12,1, as having the clinical picture both types of contractures. We have developed and applied a system of examinations, modeling expected outcome of selective neurotomy motor nerves of the upper limb, which allows to estimate the possible result of such treatment, and clearly differentiate tonic and fixed contracture. Results and conclusions. Based on the results of study we supposed that, using diagnostic blockade motor nerve at the period of planning surgical treatment help us to create temporary reversible model of selective neurotomy motor nerve branches and identify the type of contracture, degree of manifestation and functional perspective.

    Aging is associated with the loss of muscle volume (MV) and force leading to difficulties with activities of daily living. However, the relationship between upper limb MV and joint strength has not been characterized for older adults. Quantifying this relationship may help our understanding of the functional declines of the upper limb that older adults experience. Our objective was to assess the relationship between upper limb MV and maximal isometric joint moment-generating capacity (IJM) in a single cohort of healthy older adults (age ≥ 65 years) for 6 major functional groups (32 muscles). MV was determined from MRI for 18 participants (75.1±4.3 years). IJM at the shoulder (abduction/adduction), elbow (flexion/extension), and wrist (flexion/extension) was measured. MV and IJM measurements were compared to previous reports for young adults (28.6±4.5 years). On average older adults had 16.5% less total upper limb MV compared to young adults. Additionally, older adult wrist extensors composed a significantly increased percentage of upper limb MV. Older adult IJM was reduced across all joints, with significant differences for shoulder abductors (pIJM was accounted for by MV changes (p≤0.027), compared to 81.0% in young adults. We conclude that for older adults, MV and IJM are, on average, reduced but the significant linear relationship between MV and IJM is maintained. These results suggest that older adult MV and IJM cannot be simply scaled from young adults.

    Measurement of upper airway resistance is of interest in sleep disordered breathing to estimate upper airway patency. Resistance is calculated with the airflow and respiratory effort signals. However, there is no consensus on a standard for upper airway resistance measurement. This study proposes a new benchmarking method to objectively compare different upper airway resistance measurement methods by objectively differentiating between breaths with inspiratory flow limitation (high resistance) and non-limited breaths (low resistance). Resistance was measured at peak-Pes, at peak-flow, at the linear portion of a polynomial equation, as an area comparative and as average resistance for an inspiration. A total of 20 patients with systematic, gold-standard esophageal pressure and nasal airflow acquisition were analyzed and 109,955 breaths were automatically extracted and evaluated. Relative resistance values in relationship to a reference resistance value obtained during wakefulness were also analyzed. The peak-Pes measurement method obtained the highest separation index with significant (p < 0.001) differences to the other methods, followed by the area comparative and the peak-flow methods. As expected, average resistances were significantly (p < 0.001) lower for the non-IFL than for the IFL group. Hence, we recommend employing the peak-Pes for accurate upper airway resistance estimation.

    Somatosensory information from the limbs reaches the contralateral Primary Sensory Cortex (S1) with a delay of 23ms for finger, and 40ms for leg (somatosensory N20/N40). Upon arrival of this input in the cortex, motor evoked potentials (MEPs) elicited by Transcranial Magnetic Stimulation (TMS) are momentarily inhibited. This phenomenon is called 'short latency afferent inhibition (SAI)' and can be used as a tool for investigating sensorimotor interactions in the brain. We used SAI to investigate the process of sensorimotor integration in the hemisphere ipsilateral to the stimulated limb. We hypothesized that ipsilateral SAI would occur with a delay following the onset of contralateral SAI, to allow for transcallosal conduction of the signal. We electrically stimulated the limb either contralateral or ipsilateral to the hemisphere receiving TMS, using a range of different interstimulus intervals (ISI). We tested the First Dorsal Interosseous (FDI) muscle in the hand, and Tibialis Anterior (TA) in the lower leg, in three separate experiments. Ipsilateral SAI was elicited in the upper limb (FDI) at all ISIs that were greater than N20+18ms (all p<.05) but never at any earlier timepoint. No ipsilateral SAI was detected in the lower limb (TA) at any of the tested ISIs. The delayed onset timing of ipsilateral SAI suggests that transcallosal communication mediates this inhibitory process for the upper limb. The complete absence of ipsilateral SAI in the lower limb warrants consideration of the potential limb-specific differences in demands for bilateral sensorimotor integration.

  4. Mammal extinctions in the Vallesian (Upper Miocene)

    Science.gov (United States)

    Agusti, J.; Moya-Sola, S.

    The term Vallesian was created by Crusafont (1950) to designate the first European Mammalian palaeofaunas containing the equid Hipparion, the remainder of the faunas being composed of typical elements coming from the Middle Miocene such as Micromeryx, Euprox, Sansanosmilus, Pseudaelurus, and Listriodon. Thus, the Aragonian-Vallesian boundary does not show a strong change among European Miocene mammalian faunas (Agusti et al., 1984). On the other hand, the Lower Vallesian/Upper Vallesian transition corresponds to a major biotic crisis. This boudnary is characterized by the disappearence of most of the Aragonian artiodactyl forms such as Protragocerus, Miotragocerus, Listriodon, Hyotherium, Parachleusastochoerus, etc. Among the rodents, this crisis affects the family Eomyidae and most of the cricetid and glirid species. On the other hand, a number of eastern elements appear in the area at the same time. This is the case of the suid Schizochoerus and the murid Progonomys. Other eastern forms are Tragoportax, Graecoryx, Adcrocuta, Paramachairodus, Microstonyx, etc. Most of these are typical elements of the next Mammal stage, the Turolian. Thus, whereas the Lower Vallesian fauna has a typical Aragonian composition except for Hipparion. After the Middle Vallesian event, the Upper Vallesian faunas are already largely Turolian in character. The possible factors involved in this extinction event are discussed.

    Abstract Autoimmune gastritis is often suspected for its hematologic findings, and rarely the diagnosis is made for the presence of gastrointestinal symptoms. Aims of this cross-sectional study were to assess in a large cohort of patients affected by autoimmune gastritis the occurrence and the pattern of gastrointestinal symptoms and to evaluate whether symptomatic patients are characterized by specific clinical features. Gastrointestinal symptoms of 379 consecutive autoimmune gastritis patients were systematically assessed and classified following Rome III Criteria. Association between symptoms and anemia pattern, positivity to gastric autoantibodies, Helicobacter pylori infection, and concomitant autoimmune disease were evaluated. In total, 70.2% of patients were female, median age 55 years (range 17–83). Pernicious anemia (53.6%), iron deficiency anemia (34.8%), gastric autoantibodies (68.8%), and autoimmune disorders (41.7%) were present. However, 56.7% of patients complained of gastrointestinal symptoms, 69.8% of them had exclusively upper symptoms, 15.8% only lower and 14.4% concomitant upper and lower symptoms. Dyspepsia, subtype postprandial distress syndrome was the most represented, being present in 60.2% of symptomatic patients. Univariate and multivariate analyses showed that age gastritis is associated in almost 60% of cases with gastrointestinal symptoms, in particular dyspepsia. Dyspepsia is strictly related to younger age, no smoking, and absence of anemia. PMID:28072728

    Full Text Available The loss of all or part of the arm is a catastrophic event for a patient and a significant challenge to rehabilitation professionals and prosthetic engineers. The large, upper extremity amputee population in India has, historically, been poorly served, with most having no access to support or being provided with ineffective prostheses. In recent years, the arrival of organisations like Otto Bock has made high quality service standards and devices accessible to more amputees. This review attempts to provide surgeons and other medical professionals with an overview of the multidisciplinary, multistage rehabilitation process and the solution options available. With worldwide upper extremity prosthesis rejection rates at significant levels, the review also describes some of the factors which influence the outcome. This is particularly relevant in the Indian context where the service can involve high cost investments. It is the responsibility of all contributing professionals to guide vulnerable patients through the process and try to maximise the benefit that can be obtained within the resources available.

    The growing importance of Kinect as a tool for clinical assessment and rehabilitation is due to its portability, low cost and markerless system for human motion capture. However, the accuracy of Kinect in measuring three-dimensional body joint center locations often fails to meet clinical standards of accuracy when compared to marker-based motion capture systems such as Vicon. The length of the body segment connecting any two joints, measured as the distance between three-dimensional Kinect skeleton joint coordinates, has been observed to vary with time. The orientation of the line connecting adjoining Kinect skeletal coordinates has also been seen to differ from the actual orientation of the physical body segment. Hence we have proposed an optimization method that utilizes Kinect Depth and RGB information to search for the joint center location that satisfies constraints on body segment length and as well as orientation. An experimental study have been carried out on ten healthy participants performing upper body range of motion exercises. The results report 72% reduction in body segment length variance and 2° improvement in Range of Motion (ROM) angle hence enabling to more accurate measurements for upper limb exercises.

    Few disorders may manifest with predominantly sleep-related obstructive breathing. Obstructive sleep apnea (OSA) is a common disorder, varies in severity and is associated with significant cardiovascular and neurocognitive morbidity. It is estimated that between 8 and 18 million people in the United States have at least mild OSA. Although the exact mechanism of OSA is not well-delineated, multiple factors contribute to the development of upper airway obstruction and include anatomic, mechanical, neurologic, and inflammatory changes in the pharynx. OSA may occur concomitantly with asthma. Approximately 74% of asthmatics experience nocturnal symptoms of airflow obstruction secondary to reactive airways disease. Similar cytokine, chemokine, and histologic changes are seen in both disorders. Sleep deprivation, chronic upper airway edema, and inflammation associated with OSA may further exacerbate nocturnal asthma symptoms. Allergic rhinitis may contribute to both OSA and asthma. Continuous positive airway pressure (CPAP) is the gold standard treatment for OSA. Treatment with CPAP therapy has also been shown to improve both daytime and nighttime peak expiratory flow rates in patients with concomitant OSA and asthma. It is important for allergists to be aware of how OSA may complicate diagnosis and treatment of asthma and allergic rhinitis. A thorough sleep history and high clinical suspicion for OSA is indicated, particularly in asthma patients who are refractory to standard medication treatments.

    Mangled describes an injury caused by cutting, tearing, or crushing, which leads to the limb becoming unrecognizable; in essence, there are two treatment options for mangled upper extremities, amputation and salvage reconstruction. With advances in our understanding of human physiology and basic science, and with the development of new fixation devices, modern microsurgical techniques and the possibility of different types of bony and soft tissue reconstruction, the clinical and functional outcomes are often good, and certainly preferable to those of contemporary prosthetics. Early or even immediate (emergency) complete upper extremity reconstruction appears to give better results than delayed or late reconstruction and should be the treatment of choice where possible. Before any reconstruction is attempted, injuries to other organs must be excluded. Each step in the assessment and treatment of a mangled extremity is of utmost importance. These include radical tissue debridement, prophylactic antibiotics, copious irrigation with a lavage system, stable bone fixation, revascularization, nerve repair, and soft tissue coverage. Well-planned and early rehabilitation leads to a better functional outcome. Despite the use of scoring systems to help guide decisions and predict outcomes, the decision to reconstruct or to amputate still ultimately lies with the surgical judgment and experience of the treating surgeon.

    Vertebral tumours arising in the upper cervical spine are rare. We present our experience in managing these neoplasms. We retrospectively reviewed the case histories of patients treated at our institution between January 2000 and June 2011. There were 9 patients with tumours in C1-C2-C3: 2metastases, 3chordomas, 2plasmocytomas, 1chondrosarcoma and 1osteochondroma. All patients complained of neck pain at the time of diagnosis. Three patients underwent an anterior and posterior approach, 3 an exclusively posterior approach and 3 an exclusively anterior surgical approach. Tumour resection was intralesional in 7 cases. Chemo-radiotherapy was used as adjuvant therapy in patients with malignant tumours. Vertebral tumours in the upper cervical spine are usually malignant. Achieving en bloc resection is particularly challenging and is technically unfeasible in many cases. This worsens the prognosis and makes adjuvant treatment very important.

    This randomized study was designed to compare the effectiveness of bilateral interpleural analgesia with lumbar epidural analgesia, on postoperative pain relief in upper abdominal surgery. The studied patients were randomely allocated into either interpleural group "IP" (n = 15) or epidural group "EP" (n = 15). In "IP" group, preanesthetic bilateral interpleural block was done using a mixture of bupivacaine 0.5% (0.8 mg/kg) and 2 mg morphine diluted to 50 ml saline for each side. In "EP" group, the same mixture-diluted in 20 ml saline-was injected in the epidural space (L2-3). The general anesthetic technique was the same in both groups. Hemodynamic, gasometric, verbal pain score (VPS) values and complications were compared in both techniques. Heart rate (HR) and mean arterial pressure (MAP) readings were in the accepted normal range in the perioperative period although significant lower readings were detected in "EP" group. No significant differences were displayed in blood gasometric variables between the two groups. There were considerable level of analgesia in both groups in the postoperative period although "EP" analgesia was superior to "IP". More pain free patients (9 versus 4) and significant lower consumption of nalbuphine were detected in "EP" group. The results of this study indicate that bilateral "IP" analgesia may offer a satisfactory analgesia for upper abdominal surgery when the use of other analgesic techniques may be contraindicated.

    When treating patients with stab injuries of the torso, clinicians often lack timely information about the degree and nature of internal organ damage. An externally observable sign significantly associated with characteristics of torso injuries may therefore be useful for practitioners. One such potential sign is the presence of wounds to the hands, sometimes sustained during victims' attempt to defend themselves during the violent altercation. Thus, the primary aim of this study was to evaluate the association between presence of upper extremity wounds and the severity of the thoracic and intra-abdominal injuries due to stabbing. This study was carried out retrospectively using data on 8714 patients with stabbing-related injuries from 19 trauma centers that participated in the Israeli National Trauma Registry (INTR) between January 1st1997 and December 31st 2013. Patients with wounds of upper extremities in addition to torso injuries (UE group) were compared to other patients with torso injuries (TO group) in terms of demographics, injury characteristics and clinical outcome. The compared groups were found to be homogeneous in terms of age and systolic blood pressure; the number of sustained torso injuries was also identical. The UE group comprised a slightly greater percentage of females, however both groups were predominantly male. Patients with upper extremity injuries had a lower proportion of internal organ damage (36% vs. 38.5%) and lower mortality (0.9% vs. 2%). The higher mortality of patients without upper extremity wounds remained significantly different even when adjusted by other epidemiological parameters (OR 2.46, 95% CI 1.33-5.08).The number of sustained upper extremity injuries was positively associated with deeper penetration of the torso by the stabbing instrument. Patients with stabbing-related upper extremity wounds had a significant survival advantage over patients without such injuries. However, a greater number of sustained upper extremity

    2017-01-01

    This book offers a detailed introduction to graph theoretic methods in profinite groups and applications to abstract groups. It is the first to provide a comprehensive treatment of the subject. The author begins by carefully developing relevant notions in topology, profinite groups and homology, including free products of profinite groups, cohomological methods in profinite groups, and fixed points of automorphisms of free pro-p groups. The final part of the book is dedicated to applications of the profinite theory to abstract groups, with sections on finitely generated subgroups of free groups, separability conditions in free and amalgamated products, and algorithms in free groups and finite monoids. Profinite Graphs and Groups will appeal to students and researchers interested in profinite groups, geometric group theory, graphs and connections with the theory of formal languages. A complete reference on the subject, the book includes historical and bibliographical notes as well as a discussion of open quest...

This publication, a group of recipes based on this new division of food groups, reflects the effort of the USDA and other groups to translate science-based research into everyday practice for Americans. Fifteen recipes (3 from each food group) show ways to use foods from each food group. They are complete with basic nutritional analyses and food group amounts.

  17. The Euclidean distortion of the lamplighter group

    Austin, Tim; Valette, Alain

    2007-01-01

    We show that the cyclic lamplighter group $C_2 \\bwr C_n$ embeds into Hilbert space with distortion ${\\rm O}(\\sqrt{\\log n})$. This matches the lower bound proved by Lee, Naor and Peres in \\cite{LeeNaoPer}, answering a question posed in that paper. Thus the Euclidean distortion of $C_2 \\bwr C_n$ is $\\Theta(\\sqrt{\\log n})$. Our embedding is constructed explicitly in terms of the irreducible representations of the group. Since the optimal Euclidean embedding of a finite group can always be chosen to be equivariant, as shown by Aharoni, Maurey and Mityagin \\cite{AhaMauMit} and by Gromov (see \\cite{deCTesVal}), such representation-theoretic considerations suggest a general tool for obtaining upper and lower bounds on Euclidean embeddings of finite groups.

    A Hausdorff topological group $(G,\\tau)$ is called locally minimal if there exists a neighborhood $U$ of 0 in $\\tau$ such that $U$ fails to be a neighborhood of zero in any Hausdorff group topology on $G$ which is strictly coarser than $\\tau.$ Examples of locally minimal groups are all subgroups of Banach-Lie groups, all locally compact groups and all minimal groups. Motivated by the fact that locally compact NSS groups are Lie groups, we study the connection between local minimality and the ...

  20. Pseudofinite groups with NIP theory and definability in finite simple groups

    CERN Document Server

    Macpherson, Dugald

    2012-01-01

    We show that any pseudofinite group with NIP theory and with a finite upper bound on the length of chains of centralisers is soluble-by-finite. In particular, any NIP rosy pseudofinite group is soluble-by-finite. This generalises, and shortens the proof of, an earlier result for stable pseudofinite groups. An example is given of an NIP pseudofinite group which is not soluble-by-finite. However, if C is a class of finite groups such that all infinite ultraproducts of members of C have NIP theory, then there is a bound on the index of the soluble radical of any member of C. We also survey some ways in which model theory gives information on families of finite simple groups, particularly concerning products of images of word maps.
