    Gooding, J. L.; Muenow, D. W.

    1977-01-01

    The vapor phase composition obtained by heating samples of the Holbrook L6 chondrite to 1300 C was determined quantitatively by Knudsen cell-quadrupole mass spectrometry. Maximum observed vapor pressures, produced at 1200 C, are reported for Na, K, Fe, and Ni, and the implications of the Na/K ratio are considered. The Fe and Ni data are discussed with attention to their migration in individual equilibrated chondrites. S2 (with minor SO2), H2O, and CO2 were also present in the high-temperature gas phase. Vesicles formed by the release of intrinsically derived volatiles are compared with vesicles in the Ibitira eucrite. Chondrite evolution is briefly discussed.

    Even if he’s recently stopped coming to CERN on his bike, Jack Steinberger and his piercing blue eyes are still regular visitors to our corridors. As he celebrates his 95th birthday, we pay tribute to one of CERN’s greatest scientists.   Jack Steinberger in 2008, pictured on the occasion of the "Accelerating Nobel" exhibition. (Image: Claudia Marcelloni/CERN) Jack emigrated from Germany to the United States in 1934 to escape the persecution of the Jews. He later went on to study under Enrico Fermi in Chicago and in the 1950s, he contributed to the development of bubble chambers. Using this new detection apparatus, he was involved in the myriad discoveries and results that led to the construction of the Standard Model. In 1961, while at Columbia University (New York), he took part in the first experiment with a high-energy neutrino beam, which gave rise to the discovery of the muon neutrino.

  13. McCauley Sinks: A compound breccia pipe in evaporite karst, Holbrook Basin, Arizona, U.S.A

    Science.gov (United States)

    Neal, J.T.; Johnson, K.S.

    2002-01-01

    The McCauley Sinks, in the Holbrook basin of northeastern Arizona, are comprised of some 50 individual sinkholes within a 3-km-wide depression. The sinks are grouped in a semi-concentric pattern of three nested rings. The outer ring is an apparent tension zone containing ring fractures. The two inner rings are semi-circular chains of large sinkholes, ranging up to 100 m across and 50 m deep. Several sub-basins within the larger depression show local downwarping and possible incipient sinkholes. Permian Kaibab Formation limestone is the principal surface lithology; the limestone here is less than 15 m thick and is near its easternmost limit. Although surface rillenkarren are present, and the sinks are seen in the Kaibab limestone outcrops, the Kaibab is mainly a passive rock unit that has collapsed into solution cavities developed in underlying salt beds. Beneath the Kaibab is Coconino Sandstone, which overlies the Permian Schnebly Hill Formation, the unit containing the evaporite rocks-principally halite in the Corduroy Member. Evaporite karst in this part of the Holbrook basin is quite different from the eastern part, probably because of the westward disappearance of the Holbrook anticline, a structure that has major joint systems that help channel water down to the salt beds farther to the east. Also, the McCauley Sinks are near the western limits of the evaporites. The structure at McCauley Sinks suggests a compound breccia pipe, with multiple sinks contributing to the inward-dipping major depression. The Richards Lake depression, 5 km southeast of McCauley Sinks, is similar in form and size but contains only a single, central sinkhole. An apparent difference in hydrogeology at McCauley Sinks is their proximity to the adjacent, deeply incised, Chevelon Canyon drainage, but the hydrologic connections are unknown. The 3-km-wide McCauley Sinks karst depression, along with five other nearby depressions, provide substantial hydrologic catchment. Because of widespread

  19. Central Calorimeter Support Cradle Jack Failure Analysis

    Energy Technology Data Exchange (ETDEWEB)

    Rudland, D.L.; /Fermilab

    1987-04-10

    The Central Calorimeter and its support cradle are to be supported by either hydraulic or mechanical jacks. If hydraulics are used, each support will use two hydraulically coupled jacks with two out of the four supports hydraulically coupled giving the effect of a three point support system. If mechanical jacks are used, all four points are used for support. Figure 2 shows two examples of jack placement on a 3.5 inch support plate. These two support scenarios lead to five jack failure cases to be studied. This report deals with the way in which a 0.25 inch drop (failed jack) at one support affects the stresses in the cradle. The stresses from each failure case were analyzed in two ways. First, stress factors, defined as quotients of stress intensities of the failed case with respect to the static case, were generated and then, hand calculations similar to those in Engineering Note 3740.215-EN-14 were done using the reaction forces from the failed case.

  7. Closed Axisymmetric Shells as Flat Jacks

    Science.gov (United States)

    Yudin, S. A.; Sigaeva, T. V.

    Buildings during exploitation can be subjected to the external loadings leading to various kinds of heterogeneous strains or tilts. There is engineering technologies of uplift and flattening of multistory buildings by means of steel shells of the closed volume which are named as flat jacks (FJs) [1]. FJ represents two circular close plates which at the outer contour are joined to torus shell. The oil could be introduced into volume by hydraulic station creating a high pressure. As a result the plates diverge and through inserts from thick plywood create powerful force. The construction and working conditions of flat lifting jacks generates a set of problems of the mathematical modeling which are interesting to study. One of the directions is the geometry optimization. In the paper, we analyze variants of the axisymmetric shells modeling FJs. Stress states of shells with different shapes are compared at the initial loading stage.

    Both lead intoxication in early childhood and deficient bilirubin-binding capacity (BBC) of blood in jaundiced neonates indicate risk for brain damage. Zinc protoporphyrin (ZPP) is a biomarker for lead intoxication (PbI) as well as well as for iron deficiency. Under the leadership of Jack Aviv, Aviv Biomedical, Inc. developed robust hematofluorometers for point-of-care assays of ZPP in blood and for the high-affinity BBC of blood. These assays use just drops of whole blood and are simple, fast and inexpensive. ZPP by hematofluorometry has been used world-wide as a primary screen for lead intoxication since 1979. Recent clinical studies enabled by an Aviv Biomedical, Inc. bilirubin hematofluorometer have renewed interest in BBC-based assessment of neurotoxicity for improved management of neonatal jaundice. This article sketches Jack Aviv's contribution to the development and application of hematofluorometry. © 2017 Wiley Periodicals, Inc.

  11. Vector-Valued Jack Polynomials from Scratch

    Directory of Open Access Journals (Sweden)

    Jean-Gabriel Luque

    2011-03-01

    Full Text Available Vector-valued Jack polynomials associated to the symmetric group S_N are polynomials with multiplicities in an irreducible module of S_N and which are simultaneous eigenfunctions of the Cherednik-Dunkl operators with some additional properties concerning the leading monomial. These polynomials were introduced by Griffeth in the general setting of the complex reflections groups G(r,p,N and studied by one of the authors (C. Dunkl in the specialization r=p=1 (i.e. for the symmetric group. By adapting a construction due to Lascoux, we describe an algorithm allowing us to compute explicitly the Jack polynomials following a Yang-Baxter graph. We recover some properties already studied by C. Dunkl and restate them in terms of graphs together with additional new results. In particular, we investigate normalization, symmetrization and antisymmetrization, polynomials with minimal degree, restriction etc. We give also a shifted version of the construction and we discuss vanishing properties of the associated polynomials.

    Energy Technology Data Exchange (ETDEWEB)

    1997-03-10

    A new heavy duty jack up, due in mid-1998, will be able to simultaneously drill and produce wells in harsher environments and deeper water than current jack ups in the worldwide fleet. Rowan Cos. Inc.`s Gorilla V is the only mobile offshore drilling unit (MODU) currently under construction in the US. Two more enhanced Gorilla design rigs are planned before the year 2000. The enhanced Gorilla class jack up represents the most technologically advanced jack up unit constructed to date. The rigs are structurally designed to meet year-round weather challenges in the harshest geographical environments. Rising demand for drilling rigs, coupled with a dwindling fleet, is generating supply shortages around the world, particularly at the high-specification end of the market. Even increasing the historical retirement age from 20 to 25 years, rig attrition continues at a level of about 18 rigs per year. Apart from the jack up market per se, however, Rowan`s strategy in designing and building enhanced Gorillas is to improve existing jack up drilling technology and offer the versatility to operate as a drilling unit, a mobile production unit, or both simultaneously in either open water locations or alongside existing platforms. The paper discusses the market for these heavy jack-ups, the use of one on the Cohasset project in Nova Scotia, the Gorilla V and enhanced Gorillas, geographical range of use, and MOPU economics.

  13. A new modified borehole jack for stiff rock

    Science.gov (United States)

    Azzam, R.; Bock, H.

    1987-07-01

    The modified borehole jacking method, as introduced by De La Cruz in 1978, has important theoretical advantages over the common method which is associated with the name Goodman. So far, however, the modified method has not succeeded, mainly due to a lack of suitable instrumentation. To overcome this problem, a new type of modified borehole jack has been designed, built and tested. The new jack incorporates two highly innovative components: a recoverable sensor for measuring tangential strain at borehole surfaces and stacked hydraulic cylinders for extra-high load outputs. The new jack has been developed to the point at which its technical feasibility under field conditions, including its capability of yielding meaningful results, is demonstrated. Calibration in a hollow steel cylinder revealed that the new modified jack yields the correct Young's modulus within an error margin of less than ±5%. In-situ jacking tests were carried out at a major dam construction site. Results were obtained from both common and modified borehole jacking and from conventional laboratory testing of drill cores. The results of these tests are presented and discussed against the background of the particular rock conditions at the site.

  16. JACK - ANTHROPOMETRIC MODELING SYSTEM FOR SILICON GRAPHICS WORKSTATIONS

    Science.gov (United States)

    Smith, B.

    1994-01-01

    JACK is an interactive graphics program developed at the University of Pennsylvania that displays and manipulates articulated geometric figures. JACK is typically used to observe how a human mannequin interacts with its environment and what effects body types will have upon the performance of a task in a simulated environment. Any environment can be created, and any number of mannequins can be placed anywhere in that environment. JACK includes facilities to construct limited geometric objects, position figures, perform a variety of analyses on the figures, describe the motion of the figures and specify lighting and surface property information for rendering high quality images. JACK is supplied with a variety of body types pre-defined and known to the system. There are both male and female bodies, ranging from the 5th to the 95th percentile, based on NASA Standard 3000. Each mannequin is fully articulated and reflects the joint limitations of a normal human. JACK is an editor for manipulating previously defined objects known as "Peabody" objects. Used to describe the figures as well as the internal data structure for representing them, Peabody is a language with a powerful and flexible mechanism for representing connectivity between objects, both the joints between individual segments within a figure and arbitrary connections between different figures. Peabody objects are generally comprised of several individual figures, each one a collection of segments. Each segment has a geometry represented by PSURF files that consist of polygons or curved surface patches. Although JACK does not have the capability to create new objects, objects may be created by other geometric modeling programs and then translated into the PSURF format. Environment files are a collection of figures and attributes that may be dynamically moved under the control of an animation file. The animation facilities allow the user to create a sequence of commands that duplicate the movements of a

    2009-05-01

    Full Text Available A 4-month-old male Jack Russell terrier was evaluated for non-painful muscle spasms and collapse associated with exercise and activity. Clinical examination revealed well-defined, non-painful hypertrophic muscles of the fore and hind limbs and exercise and excitement induced hindquarter bunny-hopping gait, which improved with activity but worsened with resting and with any sudden changes in direction of movement. Neurological examination and routine laboratory testing showed no abnormalities. DNA analysis for myotonia congenita showed the dog to have a gene mutation in the chloride ion channel, diagnostic for myotonia congenita, which has not been reported in the Jack Russell terrier breed.

    A parasitological survey of freshwater fishes in the Big Thicket National Preserve in southeast Texas revealed myxozoan infections in two species of sunfish, Lepomis marginatus Holbrook and Lepomis miniatus Jordan (Perciformes: Centrarchidae). Pseudocysts were elongate-oval, 988 × 485 µm (ex L. marginatus) and 800 × 606 µm (ex L. miniatus) and demonstrated a predilection to the edge of the primary gill lamellae. Myxospores consistent with the genus Myxobolus were oblong, 16.8-21.3 (19.0 ± 0.9) µm long, 7.0-8.8 (7.9 ± 0.5) µm wide and 5.3-6.1 (5.8 ± 0.3) µm thick (ex L. marginatus) and 17.2-20.3 (18.8 ± 0.7) µm long, 7.5-9.9 (8.7 ± 0.6) µm wide, and 6.8-7.2 (7.0 ± 0.2) µm thick (ex L. miniatus); with 2 pyriform polar capsules 8.3-9.8 (9.0 ± 0.5) µm long, 2.2-2.7 (2.5 ± 0.2) µm wide (ex L. marginatus) and 9.2-10.5 (10.0 ± 0.4) µm long, 2.2-3.0 (2.8 ± 0.2) µm wide (ex L. miniatus). Statistically, the measurements of spore body width, polar capsule length, and polar capsule width were significantly different between myxospores from L. marginatus and L. miniatus. However, intraspecific genetic variability between isolates at the 18S rRNA gene was negligible, with 2,000 bp of sequence. The isolates shared no significant sequence similarity with any myxozoan deposited in the GenBank nucleotide database. Phylogenetic analysis inferred from the 18S rRNA gene from both L. marginatus and L. miniatus placed the isolates within a clade of myxozoan parasites of perciform fishes. Based on shared tissue and host family tropism, overlapping morphological characters and high degrees of sequence conservation at the 18S rRNA gene, we propose these isolates as morphologically distinct, genetically conspecific representatives of M. lepomis n. sp. from the gills of L. marginatus and L. miniatus in the Big Thicket National Preserve in Texas, USA.

    Full Text Available Jack was born and grew up in Lock Haven Pennsylvania, the son of William G. Holland and Florence (Davies Holland. He had an older brother, William and a younger brother, Donald. Jack spent much of his boyhood roaming the surrounding flood plains of the West Branch of the Susquehanna River looking for arrowheads. As Jack recalled, his parents gave him a great deal of freedom, just asking that he be home in time for dinner. Dr. T. B. Stewart, a Lock Haven dentist, encouraged Jack’s early archaeological interest, helping him to identify specimens. Dr. Stewart had an extensive archaeological collection and had worked with Donald Cadzow, Pennsylvania’s State Archaeologist (1929-1939. Dr. Stewart was also one of the founders of the Society for Pennsylvania Archaeology, an organization with which Jack would later become involved and that bestowed their J. Alden Mason Award on him as a professional who encouraged society members in the “proper pursuit of archaeology.”

  9. Producers tap into marginal wells with compact hydraulic jack

    Energy Technology Data Exchange (ETDEWEB)

    Anon.

    2006-05-15

    Rising oil prices have led to a renewed interest in shallow, marginal wells throughout Alberta. Almost 70 per cent of all wells drilled in the Western Canadian Sedimentary Basin (WCSB) in 2005 were less than 1,143 metres deep. This article examined the recent introduction of a small reciprocating hydraulic lift called the Copperhead, which was designed specifically for shallow wells. The smaller unit is expected to be a more cost-effective option for shallow wells, and has a maximum stroke length of 64 inches and a lift capacity of 14,000 pounds. The engine burns considerably less fuel than larger hydraulic jacks. The jack fits into the back of a half tonne truck and bolts directly on to the well head, thereby eliminating the need for a concrete pad, picker truck and crew to haul it. Although the jack is a downsized version of a larger hydraulic unit, it has fewer moving parts, is easy to use, and has far lower maintenance requirements. Stroke length, strokes per minute and gas locking can be adjusted in seconds without stopping the unit as the polish rod travels inside the hydraulic cylinder, which saves time when dewatering shallow gas wells. It was concluded that the Copperhead's portability may create opportunities to optimize shut-in wells that were abandoned due to liquid loading issues. It was noted that flexibility and cost management is essential in the low-margin field of coalbed methane production. 2 figs.

    2017-02-01

    Scoliosis surgery is one of the most difficult orthopedic surgery that have been committed today as the failure rate of orthopedic surgery for adult patients is 15%. Aside from the long duration of surgery, this surgical failure is caused by failure in biomedical instrumentation. Furthermore, this kind of failure is causing inefficiency of the surgery. With current known orthopedic surgery method, three surgeons are needed in a single orthopedic surgery. In fact, a single surgery can take up to 8 hours to be done, which increases the risk of surgical failure. Based on this problem, authors hope that our orthopedic jacks could solve the problem.

    Full Text Available The aim of this study was to analyze the relationships between the head-out aquatic exercise "Jumping jacks" kinematics and the musical cadence in healthy and fit subjects. Five young women, with at least one year of experience conducting head- out aquatic programs were videotaped in the frontal plane, with a pair of cameras providing a double projection (above and below the water surface. Subjects performed an incremental protocol of five bouts (120 b·min-1, 135 b·min-1, 150 b·min-1, 165 b·min-1 and 180 b·min-1 with 16 full cycles of the "Jumping jacks" exercise. Data processing and calculation of upper limbs' (i.e. hands, lower limbs' (i.e. feet and center of mass' 2D linear velocity and displacement were computed with the software Ariel Performance Analysis System and applying the 2D-DLT algorithm. Subjects decreased the cycle period during the incremental protocol. Significant and negative relationships with the musical cadence were verified for the center of mass and upper limbs vertical displacement. On the other hand, for the lower limbs lateral velocity, a significant and positive relationship was observed. It is concluded that expert and fit subjects increase the lower limb's velocity to maintain the range of motion, while the upper limb's displacement is reduced to coupe the music cadence.

    Full Text Available A Scissor Jack is a mechanical device used to lift a heavy vehicle from the ground for changing the wheel and for maintenance purpose. The most important fact of a jack is that it gives the user a mechanical advantage by changing the rotational motion into linear motion and allowing user to lift a heavy car to the require height. In this work we have designed different components of scissors jack using CAE tools i.e. CATIA andCalculate stresses induced in its different part which are responsible for failure and To Reduce its cost so that everyone can afford this. We have taken reference of Mahindra Bolero Scissors Jack. The Dimensions of scissors jack was measured by Vernier caliper. By measuring all the dimensions of components of scissors jack we have designed it in CATIA after that we assemble all the components of Jack to shape a model of scissors jack and calculated different parameters Max. shear stress Max. principal Tensile Stress Total torque required to lift the vehicle etc which is used in all components of scissors jack to avoid failure. To reduce the cost of jack we have taken two different sections of three different materials i.e. Mild Steel AISI 1045 grade Steel GS-52.3 Cast Steel and comparing which will be suited for above mentioned purpose. By using these materials we have calculate and compare the Strength to weight ratio and find which material is best suited for high load carrying capacity with minimum failure or deformation.

    The discovery of Hadean to Paleoarchean zircons in a metaconglomerate from Jack Hills, Western Australia, has catalyzed intensive study of these zircons and their mineral inclusions, as they represent unique geochemical archives that can be used to unravel the geological evolution of early Earth. Here, we report the occurrence and physical properties of previously undetected CO2 inclusions that were identified in 3.36-3.47 Ga and 3.80-4.13 Ga zircon grains by confocal micro-Raman spectroscopy. Minimum P-T conditions of zircon formation were determined from the highest density of the inclusions, determined from the density-dependence of the Fermi diad splitting in the Raman spectrum and Ti-in-zircon thermometry. For both age periods, the CO2 densities and Ti-in-zircon temperatures correspond to high-grade metamorphic conditions (≥5 to ≥7 kbar/ 670 to 770 °C) that are typical of mid-crustal regional metamorphism throughout Earth's history. In addition, fully enclosed, highly disordered graphitic carbon inclusions were identified in two zircon grains from the older population that also contained CO2 inclusions. Transmission electron microscopy on one of these inclusions revealed that carbon forms a thin amorphous film on the inclusion wall, whereas the rest of the volume was probably occupied by CO2 prior to analysis. This indicates a close relationship between CO2 and the reduced carbon inclusions and, in particular that the carbon precipitated from a CO2-rich fluid, which is inconsistent with the recently proposed biogenic origin of carbon inclusions found in Hadean zircons from Jack Hills.

  8. 3-D habitat suitability of jack mackerel Trachurus murphyi in the Southeastern Pacific, a comprehensive study

    South Pacific jack mackerel, Trachurus murphyi, has an ocean-scale distribution, from the South American coastline to New Zealand and Tasmania. This fish, captured by Humans since the Holocene, is nowadays heavily exploited and its population has decreased substantially since the mid-1990s. The uncertainty associated to jack mackerel population structure currently hampers management. Several hypotheses have been proposed from a single population up to several discrete populations. Still no definitive answer was given. Determining how environmental conditions drive jack mackerel distribution can provide insights on its population structure. To do so, here we performed in three steps. First, we used satellite data to develop a statistical model of jack mackerel horizontal habitat suitability. Model predictions based on interaction between temperature and chlorophyll-a match the observed jack mackerel distribution, even during extreme El Niño event. Second, we studied the impact of oxygen and show that jack mackerel distribution and abundance is correlated to oxygen over a wide variety of scales and avoid low oxygen areas and periods. Third, on the basis of the above we built a conceptual 3D model of jack mackerel habitat in the Southeastern Pacific. We reveal the presence of a low suitable habitat along the Chilean and Peruvian coast, figuratively presenting a closed door caused by a gap in the horizontal habitat at ∼19-22°S and a shallow oxycline off south-centre Peru. This kind of situation likely occurs on a seasonal basis, in austral summer but also at longer temporal scales. A lack of exchanges at some periods/seasons partially isolate jack mackerel distributed off Peru. On the other hand the continuity in the habitat during most of the year explains why exchanges occur. We conclude that the more likely population structure for jack mackerel is a pelagic metapopulation.

  9. Hydraulic adjustment in jack pine and black spruce seedlings under controlled cycles of dehydration and rehydration.

    Science.gov (United States)

    Blake, Terence J.; Li, Jiyue

    2003-04-01

    Drought adjustments were compared in black spruce (Picea mariana[Mill] B.S.P), and jack pine (Pinus banksiana[Lamb.]) by subjecting seedlings to five cycles of dehydration and rehydration. A computer-controlled root misting chamber system, supplied low (-1.5 MPa), moderate (-2.0 MPa), and severe (-2.5 MPa) dehydration, respectively, in cycles 1, 3 and 5. Although cell water relations failed to adjust to chronic dehydration, there was limited osmotic adjustment in black spruce (cycle 3), and water was re-allocated from the apoplast to the symplast in jack pine (cycles 1 and 3). Dehydration postponement was more important than dehydration tolerance. Jack pine was better able to postpone dehydration than black spruce. Specific conductivity, the hydraulic conductivity per unit stem cross-sectional area, was lower in jack pine and slower to decline during chronic dehydration. When specific conductivity was corrected for the greater leaf area in black spruce, the leaf-specific conductivity did not differ in the two species. There was no increase in needle leakage in jack pine and stomata in jack pine seedlings reopened fully after rehydration. Black spruce was more of a 'water spender', and less water stress (-2.0 MPa, cycle 3) was required to lower specific conductivity, compared to jack pine (-2.5 MPa, cycle 5). Leakage from needle membranes increased in black spruce, and stomata failed to reopen after rewatering (cycles 3 and 5). A greater needle area, smaller root system, and a higher specific conductivity lowered the water stress threshold for cavitation in black spruce, which is confined to moister sites in the boreal forest. Jack pine had a larger root system, smaller needle area and lower specific conductivity than black spruce. Because of these static features, jack pine is more drought tolerant and it is often found on sites that are too hot and dry for black spruce.

    The Jack Rabbit experiments, performed by Lawrence Livermore National Laboratory, focus on detonation wave corner turning and shock desensitization. Indeed, while important for safety or charge design, the behaviour of explosives in these regimes is poorly understood. In this paper, our temperature based reactive burn model is calibrated for LX-17 and compared to the Jack Rabbit data. It is shown that our model can reproduce the corner turning and shock desensitization behaviour of four out of the five experiments.

  18. Jacking mechanism for upper internals structure of a liquid metal nuclear reactor

    Science.gov (United States)

    Gillett, James E.; Wineman, Arthur L.

    1984-01-01

    A jacking mechanism for raising the upper internals structure of a liquid metal nuclear reactor which jacking mechanism uses a system of gears and drive shafts to transmit force from a single motor to four mechanically synchronized ball jacks to raise and lower support columns which support the upper internals structure. The support columns have a pin structure which rides up and down in a slot in a housing fixed to the reactor head. The pin has two locking plates which can be rotated around the pin to bring bolt holes through the locking plates into alignment with a set of bolt holes in the housing, there being a set of such housing bolt holes corresponding to both a raised and a lowered position of the support column. When the locking plate is so aligned, a surface of the locking plate mates with a surface in the housing such that the support column is then supported by the locking plate and not by the ball jacks. Since the locking plates are to be installed and bolted to the housing during periods of reactor operation, the ball jacks need not be sized to react the large forces which occur or potentially could occur on the upper internals structure of the reactor during operation. The locking plates react these loads. The ball jacks, used only during refueling, can be smaller, which enable conventionally available equipment to fulfill the precision requirements for the task within available space.

In this paper, an investigation into extending the length of the jack up leg is carried out in order to study the enhancement of the rig capability to drill in deeper water approaching the range of the Semisubmersible Drilling Unit (SSDU (300-1000ft. A study of the performance of a deep-water jack-up unit is performed with different leg lengths. Typical leg scantling dimensions and identical external loads are assigned, and then a detailed Finite Element Analysis (FEA model is created in order to simulate the jack-up leg unit’s structural behavior. A Multi-point Constraint (MPC element together with the spring element is used to deal with the boundary conditions. Finally, a comparative analysis for five leg lengths is carried out to illustrate their performance, including the ultimate static strength, and weight.

  20. Fracture and Delamination Assessment of Prestressed Composite Concrete for Use with Pipe Jacking Method

    2015-01-01

    Full Text Available Prestressed composite concrete pipe (PCCP has been widely used in water-transmission line and has been proven with many advantages over pure concrete or steel pipes, such as high performance with relatively low cost for materials as well as simplified installation and construction process. Recent efforts have been made to enable the PCCP structure suitable for pipe jacking method so as to replace the conventional cut and cover method. In this way, the construction time, disturbance to nearby structures, and the cost can be greatly reduced. In this paper, we present the full-scale experimental and numerical studies of PCCP and the evaluation of fracture and delamination behaviour of the structure when it is used with pipe jacking construction method subjected to various jacking forces and ground conditions.

  1. The Bildungsroman Tradition: The Philosophical Maturation of Jack Burden in All the King’s Men

    2017-11-01

    Full Text Available This paper aims to sketch out the transformation that Jack Burden—the main character in the novel—had gone through. With all the political leanings in Warren’s All the king’s Men, Jack burden seems to have had developed his own theories of dealing with life and people all through his life. He has always suffered an inferiority complex, rendering himself unworthy of being a real human being. This paper claims that Jack’s philosophical transformation has passed through three distinct phases; he had changed from a carefree idealist to a man of moral responsibility much similar to a Bildungsroman style of character maturation. Difficult times that Jack Burden has gone through caused his awakening at the end of the novel ushering his maturation

    2017-03-01

    A controversial discussion in the musical community regards the ability of the harpsichord to produce sound level or timbre changes. The jack velocity (controlled in real time within a musical context) and the plectrum shape (modified by the musician or maker prior to the performance) appear to be the two control parameters at the disposal of the harpsichord makers and players for shaping the sound. This article initiates the acoustical study of the control parameters of the harpsichord, presenting a framework for the investigation of these two parameters with means of experimental mechanics measurement. A robotic finger is used for producing repeatable plucks with various jack velocities and plectrum shapes. The plectrum bending, vibrating string's initial conditions, and radiated sound are recorded and analysed. First, results are obtained from measurements carried out on one string, for four plectrum shapes and four jack velocities. The plectrum shape has been found to have an influence on its bending behavior when interacting with the string; on the string's initial conditions (position and velocity); and on the resulting sound (sound level, spectral centroid, and decay time). The jack velocity does not have an influence on any of the measured quantities.

    Among the technologies used to recuperate cadmium (Cd) contaminated soils, phytoextraction are particularly important, where the selection of suitable plants is critical to the success of the soil remediation. Thus, the objectives of this study were to evaluate the responses of jack-bean and sorghum to Cd supply and to quantify Cd accumulation by these species grown in hydroponic culture. The plants were subjected to 0, 15, 30, or 60 μmol Cd L(-1) in the nutrient solution, and gas exchange, plant growth and Cd accumulation were measured at 25 days after starting Cd treatments. The Cd supply severely reduced growth of shoots and roots in both species. In jack-bean, Cd decreased photosynthesis by 56-86%, stomatal conductance by 59-85% and transpiration by 48-80%. The concentrations and amounts of Cd accumulated in the plant tissues were proportional to the metal supply in the nutrient solution. Sorghum was more tolerant than jack-bean to Cd toxicity, but the latter showed a greater metal concentration and accumulation in the shoot. Therefore, jack-bean would be more suitable than sorghum for use in Cd phytoremediation programs based on phytoextraction.

  15. The static strength and behaviour of joints in jack-up rigs

    Several different types of joints exist in jack-up rigs. These are in general different from those in fixed platforms. The steels used are of significantly higher strength than those used in jackets, with nominal yield strengths typically of 100 ksi (690 MPa) and with ratios of yield to ultimate strength in the range 0.9 to 0.95. Published test data for the performance of high strength joints is very limited amounting to only eleven results. A comparison of the test data with equations used to predict the static strength of joints in fixed platforms shows that in most cases the mean equations over predict the measured strength; the differences can be as high as 35%. Failure modes for high strength joints typical of those used in jack-ups has been considered. Given the very limited database of test results for high strength steel joints and the absence of data for many loading modes, configurations and geometries, the degree of conservatism present in existing joint designs is uncertain. However few joint failures have been observed to date, as a result of extreme loadings. Joints in jack-up legs are repetitive in nature. Any underestimation of capacity may, therefore, have an impact on a large proportion of joints in the same leg. Therefore, this issue requires careful consideration in jack-up strength evaluations, redundancy calculations and in the choice of suitable safety factors. (author)

  3. Operational principle, testing, and applications of the AWID-flat jack for absolute stress determinations using voltage measurements

    Kessels, W.

    1986-07-01

    Stress measurements can be performed with the, measuring principle for a flat jack discussed in this paper without any material parameters of the flat jack being of influence. This means that no calibration measurements are required by this flat jack for absolute measurements and there is no dependence on temperature. It is called “Absolut Widerstands Druckmesskissen” or short AWID-Flat Jack. Basis of evaluation is a change in the electrical resistivity of the flat jack, which is caused by two metal sheets separating from each other when inflated with hydraulic oil as soon as the external pressure is reached. Besides theoretical considerations concerning the mode of operation of the flat jack, this paper presents laboratory measurements performed in an autoclave as well as in a tube filled with salt grit under a uniaxial press. Changes of stress can be measured if the flat jack is cemented into a borehole under initial stress. The absolute stress of the bedrock can be measured after a certain time of adjustment in rock capable of creep (salt, clay, etc.). The advantages of the AWID measuring system are confirmed by in situ-measurements in a salt pillar loadable with variable pressure. In a temperature experiment at the Asse salt mine (Federal Republic of Germany) where the salt was heated up to 200°C, the advantages of the AWID measurement system were confirmed.

    Metasediments of the Jack Hills contain the oldest known terrestrial minerals in the form of zircons nearly 4.4 billion years old. Paleointensity data from these zircons provide evidence for a Hadean geodynamo as old as 4.2 billion years old. Given the importance of these zircons for constraining the earliest history of the core, it is vital to understand the fidelity of the zircon record. A fundamental aspect providing context for the preservation of primary magnetic signals is the nature of overprints predicted to have been imparted on rocks of the Jack Hills due to Archean to Proterozoic metamorphic events. To be viable magnetic records of a Hadean geodynamo, zircon magnetization directions should differ from these secondary magnetizations. To evaluate these secondary magnetizations, we report paleomagnetic analyses of a comprehensive sampling of 68 quartzite cobble-sized clasts from the Jack Hills metasediments ∼0.5 to 1.0 km from the Discovery Site (which has yielded the oldest zircons and paleofield estimates). While application of standard paleomagnetic tests suggests that the ensemble of cobble directions cannot be distinguished from those drawn from a random distribution, a new cluster analysis of directions on a sphere and non-parametric resampling approaches reveal significant directions amongst subsets of the data. One, isolated at the lowest temperature analyzed [200 to 300 °C, Declination (Dec.) = 316.8°, Inclination (Inc.) = - 51.1 °] appears to be dominated by the present day field. Another, isolated at higher (but still relatively low unblocking temperatures that we call "intermediate", of ∼350-500 °C, Dec. = 243.8°, Inc. = 9.5°) agrees with a magnetic overprint isolated from the secondary Cr-Fe mica fuchsite isolated from the Jack Hills Discovery site, passing a field test at the 80% confidence level. No evidence is found in our data, or in the data of others collected on similar Jack Hills lithologies, for a widespread 1 Ga

    Branched gold nanoparticles were prepared by a seed-mediated approach using per-6-thio-6-deoxy-β-cyclodextrin capped gold nanospheres as seeds and a growth medium similar to those commonly employed to prepare gold nanorods, containing AgNO3, ascorbic acid and cetyltrimethylammonium bromide. Novel jack-shaped gold nanoparticles (102-105 nm) were obtained at a specific range of Ag(+) ion concentrations (62-102 μM). The crystalline structure of these nanoparticles was confirmed by high-resolution transmission electron microscopy. The influence of the perthiolated β-cyclodextrin on the successful preparation of gold nanojacks was demonstrated. The jack-shaped gold nanoparticles showed strong absorption in the near infrared region and excellent catalytic activity for the electrochemical oxidation of H2O2.

    The zero-temperature phase diagrams of the antiferromagnetic Union Jack and checkerboard lattices, with spin one and an easy-plane single anisotropy term, are studied using the SU(3) Schwinger boson formalism (also known as flavor wave theory). We find that the Union Jack lattice has a quantum phase transition (QPT) at J2/J1 = 0.707 between a Néel and a collinear phase, while the checkerboard lattice has a QPT at J2/J1 = 0.785, from the Néel to a magnetically disordered phase. The ground state phase diagrams of the two models are different, both from each other and from that of the square lattice antiferromagnet with all the next nearest neighbors. For the checkerboard lattice, we calculate the spin gap and the ground state energy in the disordered phase. This phase is a candidate for a spin liquid state.

    The cutting off column and jacking technology is a method for increasing story height, which has been widely used and paid much attention in engineering. The stiffness will be changed after the process of cutting off column and jacking, which directly affects the overall seismic performance. It is usually necessary to take seismic strengthening measures to enhance the stiffness. A five story frame structure jacking project in Jinan High-tech Zone was taken as an example, and three finite element models were established which contains the frame model before lifting, after lifting and after strengthening. Based on the stiffness, the dynamic time-history analysis was carried out to research its seismic performance under the EL-Centro seismic wave, the Taft seismic wave and the Tianjin artificial seismic wave. The research can provide some guidance for the design and construction of the entire jack lifting structure.

  14. The Jack Wills crowd: towards a sociology of an elite subculture.

    Science.gov (United States)

    King, Anthony; Smith, Daniel

    2017-05-16

    British sociologists have long been interested in youth sub-cultures. However British sociologists have tended to focus on working class subcultures and avoided engagement with exclusive sub-cultures of elite social groups. This article seeks to attend to this gap by examining the subculture of a British elite: ex-public school students at select universities in the UK in the twenty-first century. This group consists of a relatively small group of young adults, aged between 18 and 23, who attended public schools, especially one of the nine Clarendon schools (Eton, Winchester, Westminster, St. Paul's, Merchant Taylor's, Shrewsbury, Rugby, Harrow and Charterhouse), and were students at a selective group of British universities, primarily Oxford and Cambridge, Durham, Bristol, Exeter, Bath, Manchester, St Andrews and Edinburgh. The article examines the way in which this group has reconfigured and re-constituted itself in the face of globalizing challenges. Specifically, it examines the way in which participation of ex-public school students in events run by and under the patronage of the high street retailing company, Jack Wills, has played a galvanising role for this group in the last decade. The Jack Wills crowd is an example of how some young adults form exclusive social networks and reproduce prevailing forms of privilege. The social networks built around the Jack Wills subculture is likely to provide them with advantages in the job market through a prodigious network of connections and patrons. The Jack Wills subculture potentially contributions to the socio-economic reproduction of the higher professional middle classes. © London School of Economics and Political Science 2017.

    2013-02-01

    To predict the long-term effects of climate change - global warming and changes in precipitation - on the diameter (radial) growth of jack pine (Pinus banksiana Lamb.) and black spruce (Picea mariana [Mill.] B.S.P.) trees in boreal Ontario, we modified an existing diameter growth model to include climate variables. Diameter chronologies of 927 jack pine and 1173 black spruce trees, growing in the area from 47°N to 50°N and 80°W to 92°W, were used to develop diameter growth models in a nonlinear mixed-effects approach. Our results showed that the variables long-term average of mean growing season temperature, precipitation during wettest quarter, and total precipitation during growing season were significant (alpha = 0.05) in explaining variation in diameter growth of the sample trees. Model results indicated that higher temperatures during the growing season would increase the diameter growth of jack pine trees, but decrease that of black spruce trees. More precipitation during the wettest quarter would favor the diameter growth of both species. On the other hand, a wetter growing season, which may decrease radiation inputs, increase nutrient leaching, and reduce the decomposition rate, would reduce the diameter growth of both species. Moreover, our results indicated that future (2041-2070) diameter growth rate may differ from current (1971-2000) growth rates for both species, with conditions being more favorable for jack pine than black spruce trees. Expected future changes in the growth rate of boreal trees need to be considered in forest management decisions. We recommend that knowledge of climate-growth relationships, as represented by models, be combined with learning from adaptive management to reduce the risks and uncertainties associated with forest management decisions. © 2012 Blackwell Publishing Ltd.

    Congenital hereditary sensorineural deafness is the most common form of deafness in dogs. The objectives of this study were to determine a reliable measure of the prevalence of deafness in Jack Russell terriers, an affected breed, and associations between deafness and phenotypic characteristics. Brainstem auditory evoked response recordings and phenotypic parameters (coat color, coat texture, sex, eye color, sire and dam hearing status) were recorded for 1009 Jack Russell terriers. The prevalence of unilateral and bilateral deafness was 3.57% and 0.50%, respectively, lower by a factor of three to four than in earlier reports based on smaller and closely related kindreds. Significant association with deafness was identified with white coat color and parental hearing status, but not with sex or coat type. Lack of significant sex or coat type associations and the significant association with white coat color are consistent with previous reports. In conclusion the prevalence of deafness in Jack Russell terriers is lower than initially reported. Deafness was associated with white coat color and parental hearing status. The association with parental hearing status supports this form of deafness being a heritable trait in the breed and the association with white coat color supports an inheritance linked to pigmentation genes.

  20. Estuaries as nurseries for the jacks Caranx ignobilis and Caranx melampygus (Carangidae) in Hawaii

    Smith, G.C.; Parrish, J.D.

    2002-01-01

    Estuaries provide juvenile nursery habitat for many species of fish that inhabit marine environments as adults. In Hawaii, some juvenile Caranx ignobilis and Caranx melampygus occupy estuaries opportunistically before moving to nearshore ocean habitats. This study examined the extent and nature of estuarine habitat available in the lower Hanalei River of Kauai, the relative abundance and distribution of jacks in the estuary, and their diets. Salinity measurements indicated that the upstream extent of saltwater ranged from the mouth to nearly 5 km upriver and was strongly influenced by the variable river discharge. Juvenile jacks between 80 and 310 mm FL were observed on underwater transects over the full range of mixohaline conditions. Hand-operated seine collections produced overall catch rates of ???0.64 fish/haul for each of these species. The two jacks ate much the same spectrum of food items. C. ignobilis was somewhat more piscivorous than C. melampygus, as determined by measures of frequency of predation and number and bulk of prey. Data for length at age, incorporating daily otolith increment counts from these estuarine juveniles and previous counts from non-estuarine specimens, were fitted to a lifetime von Bertalanffy growth model. The results greatly extended the age range of the model and suggested that growth rates were not much different between estuarine and non-estuarine fish. ?? 2002 Elsevier Science Ltd.

  4. Secondary vegetation succession on jack pine (Pinus banksiana) cutovers in northeastern Ontario, Canada

    Energy Technology Data Exchange (ETDEWEB)

    2000-07-01

    The effects of different harvesting and site preparation methods on competing vegetation were studied in nine jack pine (Pinus banksiana) cutovers in northeastern Ontario, Canada. Six different treatments plus glyphosate herbiciding and no herbiciding were applied: 1) tree-length harvesting followed by trenching, and full-tree harvesting followed by five site preparations, 2) no site preparation, 3) trenching and 4) blading and compaction as well as blading followed by two planting densities, 5) 1.2m and 6) 2m. Competing vegetation was assessed preharvest and years 1, 2, 3, and 5 postharvest. Data was also available from nine juvenile sites as well as nine semimature sites. Data collection consisted of coverage values of each species as well as structural data for main life forms in height classes. Growth and health data of the planted jack pine seedlings were also available. The data was analyzed using detrended correspondence analysis (DCA), diversity indices and tabular analysis. Three years after the herbicide application there is no difference between the total coverage in the halfplots that have received herbiciding and those that have not, but an alteration of the relative abundance of species groups has developed; glyphosate herbiciding promotes grasses over shrubs. When no site preparation is applied, shrubs increase and compete with the seedlings, whose growth is cut in half compared to the ones that have been site prepared by trenching. Five years after blading, and blading plus compaction, there is still very little vegetation in the research plots, but there is no reduction of the survival rate and growth of the jack pine seedlings. More dense planting after this treatment leads to more competing vegetation, probably due to increased availability of moisture. Grasses do not seem to be affected by compaction and pioneer mosses are promoted by this treatment but compaction leads to a significant reduction of the total coverage of competing vegetation

    A lectin specific for N-acetylgalactosamine was isolated from seed extract of Jack fruit (Artocarpus heterophyllus) by ammonium sulfate precipitation, followed by affinity chromatography on a Affigel-galactosamine-agarose column. The lectin possessed agglutinating activities for human and rat sperm as well as human red blood cells. It was found to have Mr = 62,000 consisting of two dissimilar subunits of Mr = 18,000 and 13,000. It also cross-reacted with an antibody against the lectin of Osage Orange (Maclura pomifera).

    A borehole jack devised for lunar exploration is described and results of its use in simulated lunar solids are presented. A hydraulic cylinder mounted between two stiff plates acts to spread the plates apart against the borehole walls when pressured. The spreading is measured by a displacement transducer and the load is measured hydraulically. The main improvement over previous instruments is the increased stroke, which allows large deformations of the borehole. Twenty-eight pistons are used to obtain a high hydraulic efficiency, and three return pistons are also provided. Pressure-deformation curves were obtained for each test on Lunar Soil Simulant No. 2, a light gray silty basalt powder.

    Bareroot jack pine (Pinus banksiana Lamb.) seedlings (2 + 0) and bareroot white spruce (Picea glauca (Moench) Voss) transplants (1 1/2 + 1 1/2) were taken from cold storage and planted on a clearcut forest site in northeastern Ontario on several dates between May 6 and June 5 during which period soil temperature at 15 cm depth increased from 0 to 18 degrees C. Additional cold-stored trees were transferred to a greenhouse where they were grown in pots for 0, 7 or 28 days and then placed with their roots in aerated water maintained at one of a range of constant temperatures between 0 and 22 degrees C. In both species, daytime xylem pressure potentials (Psi(x)) and needle conductances (g(wv)) decreased with decreasing soil or water temperature. At all root temperatures, g(wv) was lower, and Psi(x) higher, in jack pine than in white spruce. After 28 days in the greenhouse, g(wv) of jack pine seedlings, and Psi(x) of white spruce, was higher than in plants just removed from cold storage. In both species, water-flow resistance through the soil-plant-atmosphere continuum (RSPAC) increased as root temperature decreased. At all root temperatures, RSPAC was higher in plants just removed from cold storage than in plants grown in the greenhouse for 28 days, during which time many new unsuberized roots were formed. At root temperatures above 10 degrees C, RSPAC of both species was higher in trees newly planted in mineral soil than in trees with roots in aerated water; presumably because the roots of planted trees had limited hydraulic contact with the soil. On the day following removal from cold storage, relative plant water flow resistance increased, in both species, more rapidly with declining root temperature than could be accounted for by the change with temperature in the viscosity of water, thus indicating an effect of temperature on root permeability. The same effect was evident in jack pine seedlings, but not white spruce transplants, that had been grown for 28 days in

    There is considerable evidence that biodiversity promotes multiple ecosystem functions (multifunctionality), thus ensuring the delivery of ecosystem services important for human well-being. However, the mechanisms underlying this relationship are poorly understood, especially in natural ecosystems. We develop a novel approach to partition biodiversity effects on multifunctionality into three mechanisms and apply this to European forest data. We show that throughout Europe, tree diversity is positively related with multifunctionality when moderate levels of functioning are required, but negatively when very high function levels are desired. For two well-known mechanisms, ‘complementarity' and ‘selection', we detect only minor effects on multifunctionality. Instead a third, so far overlooked mechanism, the ‘jack-of-all-trades' effect, caused by the averaging of individual species effects on function, drives observed patterns. Simulations demonstrate that jack-of-all-trades effects occur whenever species effects on different functions are not perfectly correlated, meaning they may contribute to diversity–multifunctionality relationships in many of the world's ecosystems.

  10. The construction of identity in a consumerist society: Delillo’s Jack Gladney

    Directory of Open Access Journals (Sweden)

    Sanja Matković

    2016-02-01

    Full Text Available This paper deals with the construction of the postmodern identity of Jack Gladney, the main character in Don DeLillo’s White Noise (1985. Employing (postmodern, social psychology, and psychoanalytic theories of Zygmunt Bauman, Erich Fromm, Jean Baudrillard, and Gilles Lipovetsky, it analyzes the construction of Gladney’s character through his social roles as professor, husband, and consumer in the narrow sense of the word in order to deduce that his consumerist practices have spread to all aspects of his life. This reading reveals a new interpretation of Gladney’s fear of death; it shows that Gladney’s thanatophobia represents a consequence of his atheistic worldview. Namely, unable to find a haven in religion, he unsuccessfully seeks the meaning of life and death elsewhere, mainly in consumerism, which is identified as the source of his alienation from himself, people, and God. This paper suggests that numerous problems of postmodern life are caused by the lack of faith in God and proposes a conclusion that religion itself could be the answer to the difficulties faced by postmodern individuals with fragmented identities such as Jack Gladney.

    Manuka honey (Leptospermum scoparium) exerts a strong antibacterial effect. Bacterial enzymes are an important target for antibacterial compounds. The enzyme urease produces ammonia and enables bacteria to adapt to an acidic environment. A new enzymatic assay, based on photometric detection of ammonia with ninhydrin, was developed to study urease activity. Methylglyoxal (MGO) and its precursor dihydroxyacetone (DHA), which are naturally present in manuka honey, were identified as jack bean urease inhibitors with IC 50 values of 2.8 and 5.0mM, respectively. Urease inhibition of manuka honey correlates with its MGO and DHA content. Non-manuka honeys, which lack MGO and DHA, showed significantly less urease inhibition. MGO depletion from manuka honey with glyoxalase reduced urease inhibition. Therefore, urease inhibition by manuka honey is mainly due to MGO and DHA. The results obtained with jack bean urease as a model urease, may contribute to the understanding of bacterial inhibition by manuka honey. Copyright © 2017 Elsevier Ltd. All rights reserved.

  12. Approach to estimating the maximum depth for glacially induced hydraulic jacking in fractured crystalline rock at Forsmark, Sweden

    Science.gov (United States)

    Lönnqvist, M.; Hökmark, H.

    2013-09-01

    Hydraulic jacking is a significant dilation of a fracture that occurs when the pore pressure within it exceeds the sum of the fracture's normal stress and tensile strength. This phenomenon may occur during a glacial period because of changes in hydraulic and mechanical boundary conditions. Since hydraulic jacking may alter flow patterns and the transport capacity of the rock mass, its possible effects on the long-term performance of a nuclear waste repository should be considered. We develop an approach to assess glacially induced hydraulic jacking in fractured crystalline rock and establish bounding estimates of the maximum jacking depth for the Swedish Nuclear Fuel and Waste Management Company's (SKB) repository site at Forsmark. The pore pressure is estimated using mechanically uncoupled two-dimensional poroelastic continuum models with hydraulic and mechanical conditions based on SKB's reconstruction of the Weichselian glaciation at this site (120-0 ka B.P.). For warm-based conditions, the water pressure at the ice/bed interface is set at 98% of the mechanical load, whereas for glacial conditions with extensive proglacial permafrost, the corresponding water pressure is set at a (lower) annual average value. We demonstrate that the pore pressure within the uppermost kilometer of rock is mainly governed by the water pressure at the ice/bed interface and that the mechanical impact of the ice load on the pore pressure is sufficiently small to be ignored. Given the current and estimated future stress conditions at Forsmark, hydraulic jacking is mainly of concern for subhorizontal fractures, i.e., it is sufficient to consider situations when the pore pressure exceeds the vertical stress. We conclude that hydraulic jacking at Forsmark will be confined to the uppermost 200 m of the rock mass.

    Jack-ups have been constructed for numerous ocean environments, but to date there has been no operating experience under Arctic sea ice conditions. The current state of jack-up technology does not allow working outside the ice-free season and thus ice management will be needed to extend the drilling season. Currently, ice load calculations are reasonably well defined for level ice, while the ice loads due to managed ice are not known evenly well. In order to extend the drilling season for mul...

  14. GPR measurements for the distribution of thixotropic slurry behind segments in large diameter and long distance pipe-jacking construction

    2013-04-01

    It is very important to form an integrated ring of thixotropic slurry around the pipe segments to reduce resistance during large diameter and long distance pipe jacking. Furthermore, the integrated slurry ring between the pipe and the excavated soil can effectively reduce the soil disturbance caused by the pipes, and minimize ground settlement. It is necessary to real-time monitor the spatial distribution of the thixotripic slurry during jacking process. The traditional solution to estimate the outlines of slurry ring is the jacking load and the injecting pressure. If the jacking load increases, which means more slurry should be injected to reduce the jacking load. However, this solution couldn't provide the distribution of the slurry beneath pipe segments, and locate the zones which need to be injected enough slurry. Ground penetrating radar (GPR) has been successfully used to detect the thickness of the grouting behind the shield tunnel segments in last several years. An important factor is the dielectric difference between grouting and soil. Similarly, the interface between the liquid slurry with high relative electric permittivity and surrounding soil, should be recognized from GPR image due to the distinct dielectric difference. Here, GPR experiment has been conducted on a sewage pipe jacking engineering. The purpose of the survey is to evaluate the distribution of the thixotropic slurry through GPR image. In this sewage jacking engineering, the width and the thickness of each pipe segments is 200 cm and 30 cm, respectively. Considering the resolution and propagation range of radar wave, ground coupled bowtie antenna of 900 MHz frequency has been selected for GPR data acquisition. A series of circular GPR data have been collected along the inner surface of pipe segments. In addition, sampling of slurry has been performed on four different segments. The relative electric permittivity and conductivity of the thixotropic slurry have been measured by using time

    Jack bean urease (EC 3.5.1.5) is a metalloenzyme, which catalyzes the hydrolysis of urea to produce ammonia and carbon dioxide. The heavy metal ions are common inhibitors to control the rate of the enzymatic urea hydrolysis, which take the Hg2+ as the representative. Hg2+ affects the enzyme activity causing loss of the biological function of the enzyme, which threatens the survival of many microorganism and plants. However, inhibitory kinetics of urease by the low concentration Hg2+ has not been explored fully. In this study, the inhibitory effect of the low concentration Hg2+ on jack bean urease was investigated in order to elucidate the mechanism of Hg2+ inhibition. According to the kinetic parameters for the enzyme obtained from Lineweaver-Burk plot, it is shown that the Km is equal to 4.6±0.3 mM and Vm is equal to 29.8±1.7 μmol NH3/min mg. The results show that the inhibition of jack bean urease by Hg2+ at low concentration is a reversible reaction. Equilibrium constants have been determined for Hg2+ binding with the enzyme or the enzyme-substrate complexes (Ki =0.012 μM). The results show that the Hg2+ is a noncompetitive inhibitor. In addition, the kinetics of enzyme inhibition by the low concentration Hg2+ has been studied using the kinetic method of the substrate reaction. The results suggest that the enzyme first reversibly and quickly binds Hg2+ and then undergoes a slow reversible course to inactivation. Furthermore, the rate constant of the forward reactions (k+0) is much larger than the rate constant of the reverse reactions (k-0). By combining with the fact that the enzyme activity is almost completely lost at high concentration, the enzyme is completely inactivated when the Hg2+ concentration is high enough. These results suggest that Hg2+ has great impacts on the urease activity and the established inhibition kinetics model is suitable.

    Background. The injured anterior cruciate ligament (ACL) has a limited healing capacity leading to persisting instability. Hypothesis/Purpose. To study if the application of a brace, producing a dynamic posterior drawer force, after acute ACL injury reduces initial instability. Study Design. Cohort study. Methods. Patients treated with the ACL-Jack brace were compared to controls treated with primary ACL reconstruction und controls treated nonsurgically with functional rehabilitation. Measurements included anterior laxity (Rolimeter), clinical scores (Lysholm, Tegner, and IKDC), and MRI evaluation. Patients were followed up to 24 months. Results. Patients treated with the ACL-Jack brace showed a significant improvement of anterior knee laxity comparable to patients treated with ACL reconstruction, whereas laxity persisted after nonsurgical functional rehabilitation. The failure risk (secondary reconstruction necessary) of the ACL-Jack group was however 21% (18 of 86) within 24 months. Clinical scores were similar in all treatment groups. Conclusion. Treatment of acute ACL tears with the ACL-Jack brace leads to improved anterior knee laxity compared to nonsurgical treatment with functional rehabilitation.

    With the syndrome of malignant narcissism, which is characterised by narcissistic personality disorder, anti-social behaviour, sadism and a marked tendency to paranoid reactions, Kernberg (1985, 1996) describes an independent form of pathological narcissism. According to Stone (1996) this is found in many mass-murderers and serial killers. On the basis of the example of Jack Unterweger the connection between malignant narcissism and sexual offence is discussed as to psychodynamic development, personality structure and psychopathology. Unterweger, who was convicted to lifelong imprisonment in 1976 for sadistic sexual murder, became a wellknown writer in prison and was released prematurely in 1990 as the Austria case of successful rehabilitation. As stated in the sentence passed against him he killed 11 prostitutes in Europe and the USA within the next 18 months, but never pleaded guilty. Psychiatric examination revealed numerous elements of malignant narcissism and the constellation of his development and life was typical of serial offenders.

    Full Text Available The fractional level models are (logarithmic conformal field theories associated with affine Kac–Moody (superalgebras at certain levels k∈Q. They are particularly noteworthy because of several longstanding difficulties that have only recently been resolved. Here, Wakimoto's free field realisation is combined with the theory of Jack symmetric functions to analyse the fractional level slˆ(2 models. The first main results are explicit formulae for the singular vectors of minimal grade in relaxed Wakimoto modules. These are closely related to the minimal grade singular vectors in relaxed (parabolic Verma modules. Further results include an explicit presentation of Zhu's algebra and an elegant new proof of the classification of simple relaxed highest weight modules over the corresponding vertex operator algebra. These results suggest that generalisations to higher rank fractional level models are now within reach.

    Full Text Available This paper analyses information on various macro environmental variables available since 1876 for the Southeast Pacific and more recent data on Jack mackerel Trachurus murphyi (Nichols, 1920 landings and biomass in the Peruvian sea, relating them to probable areas of water masses equivalent to Cold Coastal Waters (CCW and Subtropical Surface Waters (SSW. It is concluded that the index of the Pacific Decadal Oscillation (PDO presents expressions of variability that are consistent with those found for the Southern Oscillation Index (SOI and that the detected changes in biomass of Jack mackerel T. murphyiin the Peruvian sea reflect changes in the availability of the fish stock associated with secular (SOI and decadal (PDO variability patterns. These fluctuations in stock availability impact fisheries in Ecuador, Peru and northern Chile, which show significant variations in their landings and would have given a biased picture of the state of abundance, leading to wrong diagnoses of the real situation of the exploited stocks. These patterns of variability would also affect the appearance of El Niño, making them start in the southern hemisphere autumn or spring depending on whether the current PDO is positive or negative. Periods of high (1876 – 1925 and 1976 – 2012 and low (1926 – 1975 variability are also identified in relation to the Euclidean distance of the variances of the SOI; and in relation to the PDO a distinction is made between warm (1925 – 1944 and 1975 – 1994, cold (1945 – 1974 and tempered or interface periods (1895 – 1924 and 1995 – 2012, the latter being explained by the interaction between periods of high variability.

    2016-04-01

    This study presents a useful analysis method for estimating simultaneously the stability, stress distribution and groundwater seepage as micro - tunnel is being advanced into the ground. The research is mainly concerned with the results of a case study conducted on a project to create a long industrial collector of effluent network in the east bank of the river Avilés (north coast of Spain). This coastal city has significant port and industrial installations in its environs. The geology of the location comprises Quaternary deposits on both flanks of the estuary and includes different highly variable geotechnical behavior. The industrial effluent network, constructed in the year 2010, has a length of 13.087 km and consists of 1.5 m diameter pipes, reaching a maximum depth of 5.8 m below the surface. Only the first 7.0 km of the collector (south area) were formed using pipe-jacking method whilst the rest were formed in open excavations or surface laid. Using the commercial software RS2, a 2D finite element program for soil and rock application, the ground response to pipe jacking in pipeline installation in Avilés was analyzed. Both axi-symmetric and plane strain analyses were carried out in RS2 to simulate in 3D the ground response to pipe advancement. The results demonstrate how much of deformation there is at ground surface in the immediate vicinity of the pipeline. The main objective is to show the possible patterns of ground subsidence and tunnel stresses to inform designers as to whether the tunnel will be stable and safe.

    Tight hamstrings are reported to be one of the causes of low back pain. However, there have been few reports on effective stretching procedures for the tight hamstrings. The so-called jack-knife stretch, an active-static type of stretching, can efficiently increase the flexibility of tight hamstrings. To evaluate hamstring tightness before and after the 4-week stretching protocol in healthy volunteer adults and patients aged under 18 years with low back pain. For understanding the hamstrings tightness, we measured two parameters including (1) finger to floor distance (FFD) and (2) pelvis forward inclination angle (PFIA). Eight healthy adult volunteers who had no lumbar or hip problems participated in this study (mean age: 26.8 years). All lacked flexibility and their FFD were positive before the experiment. Subjects performed 2 sets of the jack-knife stretch every day for 4 weeks. One set consisted of 5 repetitions, each held for 5 s. Before and during the 4-week experiment, the FFD and PFIA of toe-touching tests were measured weekly. For 17 of the sports players aged under 18, only FFD was measured. In adult volunteers, FFD was 14.1 ± 6.1 cm before the experiment and decreased to -8.1 ± 3.7 cm by the end of week 4, indicating a gain in flexibility of 22.2 cm. PFIA was 50.6 ± 8.2 before the experiment and 83.8 ± 5.8 degrees after. Before and after the experiment, the differences were significant (p stretching, respectively. This difference was significant (p stretch is a useful active-static stretching technique to efficiently increase flexibility of tight hamstrings.

    1999-01-01

    This paper describes the human engineering analysis performed on the Materials Science Research Rack-1 and Quench Module Insert (MSRR-1/QMI) using Transom Jack (Jack) software. The Jack software was used to model a virtual environment consisting of the MSRR-1/QMI hardware configuration and human figures representing the 95th percentile male and 5th percentile female. The purpose of the simulation was to assess the human interfaces in the design for their ability to meet the requirements of the Pressurized Payloads Interface Requirements Document - International Space Program, Revision C (SSP 57000). Jack was used in the evaluation because of its ability to correctly model anthropometric body measurements and the physical behavior of astronauts working in microgravity, which is referred to as the neutral body posture. The Jack model allows evaluation of crewmember interaction with hardware through task simulation including but not limited to collision avoidance behaviors, hand/eye coordination, reach path planning, and automatic grasping to part contours. Specifically, this virtual simulation depicts the human figures performing the QMI installation and check-out, sample cartridge insertion and removal, and gas bottle drawer removal. These tasks were evaluated in terms of adequate clearance in reach envelopes, adequate accessibility in work envelopes, appropriate line of sight in visual envelopes, and accommodation of full size range for male and female stature maneuverability. The results of the human engineering analysis virtual simulation indicate that most of the associated requirements of SSP 57000 were met. However, some hardware design considerations and crew procedures modifications are recommended to improve accessibility, provide an adequate work envelope, reduce awkward body posture, and eliminate permanent protrusions.

    Full Text Available The secondary compounds of pines (Pinus can strongly affect the physiology, ecology and behaviors of the bark beetles (Coleoptera: Curculionidae, Scolytinae that feed on sub-cortical tissues of hosts. Jack pine (Pinus banksiana has a wide natural distribution range in North America (Canada and USA and thus variations in its secondary compounds, particularly monoterpenes, could affect the host expansion of invasive mountain pine beetle (Dendroctonus ponderosae, which has recently expanded its range into the novel jack pine boreal forest. We investigated monoterpene composition of 601 jack pine trees from natural and provenance forest stands representing 63 populations from Alberta to the Atlantic coast. Throughout its range, jack pine exhibited three chemotypes characterized by high proportions of α-pinene, β-pinene, or limonene. The frequency with which the α-pinene and β-pinene chemotypes occurred at individual sites was correlated to climatic variables, such as continentality and mean annual precipitation, as were the individual α-pinene and β-pinene concentrations. However, other monoterpenes were generally not correlated to climatic variables or geographic distribution. Finally, while the enantiomeric ratios of β-pinene and limonene remained constant across jack pine’s distribution, (‒:(+-α-pinene exhibited two separate trends, thereby delineating two α-pinene phenotypes, both of which occurred across jack pine’s range. These significant variations in jack pine monoterpene composition may have cascading effects on the continued eastward spread and success of D. ponderosae in the Canadian boreal forest.

    Full Text Available Dryers heated by solar energy have been constructed and used in drying whole and half jack fruit almonds. The samples were dried during the day in direct sun and in the conventional solar dryer prepared for this purpose. Another piece of equipment was built for reception and accumulation of sun energy in a body of water, which was used as a heat source for night drying. The drying with the sun energy was compared with artificial drying. The jack fruit almonds were dried whole, half, with pellicle and without it. The storage of solar energy in water was technically viable for use in night drying. The drying by combining solar dryers in the day and night periods were completed in approximately 35 hours, and were equivalent to artificial drying between 40ºC and 70ºC. Almond cut in half and the pellicle removed reduced the drying time.Secadores com aquecimento por energia solar foram construídos e utilizados em secagens de amêndoas de jaca inteiras e em metades. As secagens no período diurno foram realizadas por exposição direta ao sol e em secador solar convencional, elaborado para este fim. Construiu-se também um equipamento para captação e acumulação de energia solar em uma massa de água, a qual foi utilizada como fonte de calor para realização de secagens no período noturno. As secagens com o uso de energia solar foram comparadas com secagens artificiais. As amêndoas de jaca foram secadas inteiras, em metades, com e sem película. O armazenamento da energia solar em corpo de água mostrou-se viável do ponto de vista técnico para utilização em secagens noturnas. As secagens combinando secadores por energia solar nos períodos diurno e noturno foram concluídas em tempos aproximados de 35 horas e equivaleram a secagens artificiais entre 40 ºC e 70 ºC. O corte das amêndoas e a retirada das películas reduziram o tempo de secagem.

    Hadean Jack Hills (Western Australia) detrital zircons represent the best documented terrestrial resource with which to observe the pre-4 Ga Earth. The >4 Ga component of this semi-continuous 4.38 to 3.0 Ga zircon record has been investigated in detail for age, δ18O, Lu-Hf systematics, and Ti thermometry. The more abundant post-Hadean population is less well-characterized, but a previous study (Bell et al., 2011) suggests a more restricted range of δ18O source materials together with a ca. 4.0-3.6 Ga discontinuity in Lu-Hf evolution. These differences could reflect a transformation in the character of the older zircon source region or their sourcing from different terranes entirely. The relative scarcity of 4.0-3.6 Ga zircons corresponds to a discontinuity in Lu-Hf evolution after which 176Hf/177Hf in zircon reverts to more radiogenic values relative to the >4 Ga population. We present new oxygen isotope, titanium, and trace element results for 4.0-3.6 Ga Jack Hills zircons in a search for apparent transitions in petrological conditions. Post-3.8 Ga zircons show a marked decrease in the occurrence of heavy oxygen (>6.5‰), but remain close to the average of the Hadean distribution despite their restricted range. This may point to the decreased importance of sedimentary materials in post-3.8 Ga magmas. Ca. 3.9 Ga zircons fall into two categories: “Group I” displays temperatures and compositions similar to the Hadean zircons whereas “Group II” zircons have higher U and Hf, and lower (Th/U), Ce and P. Group II zircons also have anomalously low Ti, and are remarkably concordant in the U-Pb system. Group II's geochemical characteristics are consistent with formation by transgressive recrystallization (Hoskin and Black, 2000), in which non-essential structural constituents are purged during high-grade thermal metamorphism. The restricted age range of Group II occurrence (3.91-3.84) and its coincidence with the postulated intense bolide flux in the inner solar

    User-generated smartphone applications have created a new level of virtual connectivity for gay males, one in which users can create profiles and meet other users as nearby or as far away as possible. For those within close proximity, the other users can be considered their "virtual neighbors." Although the applications are theoretically designed to be places of inclusion and not exclusion, where any gay male with economic means can download an application, many profiles have been created that exclude other users. Through an examination of profiles on one such application, Jack'd, exclusion is found in the way users celebrate and reinforce ideas of traditional masculinity and denigrate and reinforce stereotypic ideas of femininity embodied by some gay men. Jack'd, and other user-generated smartphone applications, can be read as virtual neighborhoods where one is excluded based on their gender performance.

    2013-01-01

    Full Text Available The paper focuses on the performance of floating buoys of a wave power generating jack-up platform called Haiyuan 1, in order to work out the optimum designed draft and hydraulic pressure. The performance of the buoy, especially its delivered power, is an important issue in designing oscillating buoy wave energy converter. In this case, major factors affect the performance including incident wave, designed draft, and hydraulic pressure on the buoy. To find out the relationship among design draft, hydraulic pressure, and delivered power, the key point is to precisely estimate wave induced motion of the buoy. Three-dimensional theory and time domain method based on potential theory were adopted in the paper. Unlike ship and other floating structures, motion of wave energy converter (WEC buoy in wave will be weakened because of energy take-off, which will cause significant draft changing with time. Thus, draft changing should be taken into consideration as well. In addition, green water problem occurs more frequently than that in ship and other floating structures and also might the reduce delivered power. Therefore, green water problem will also be taken into account when choosing the optimum designed draft and hydraulic pressure. The calculation indicates that the optimum designed draft is 0.935 m, while the optimum designed hydraulic pressure is 30 kN.

    2017-06-01

    For each irreducible module of the symmetric group S_{N} there is a set of parametrized nonsymmetric Jack polynomials in N variables taking values in the module. These polynomials are simultaneous eigenfunctions of a commutative set of operators, self-adjoint with respect to two Hermitian forms, one called the contravariant form and the other is with respect to a matrix-valued measure on the N-torus. The latter is valid for the parameter lying in an interval about zero which depends on the module. The author in a previous paper [SIGMA 12 (2016), 033, 27 pages] proved the existence of the measure and that its absolutely continuous part satisfies a system of linear differential equations. In this paper the system is analyzed in detail. The N-torus is divided into (N-1)! connected components by the hyperplanes x_{i}=x_{j}, i

    Fu, Y B; Knowles, P; Perry, D J

    1992-02-01

    Pollen pool heterogeneity, which violates an assumption of the mixed-mating model, is a major potential problem in measuring plant mating systems. In this study, isozyme markers were used to examine pollen pool heterogeneity in two natural populations of jack pine, Pinus banksiana Lamb., in northwestern Ontario, Canada. Population multilocus estimates of outcrossing rate ranged from 0.83 to 0.95 and differed significantly between populations. Single-tree multilocus outcrossing rates were found to be homogeneous among trees in both populations. Computer simulation studies indicated that a consanguineous pollen pool (pollen gametes related to the mother tree) was capable of biasing population outcrossing estimates downward. Random pollen pool heterogeneity (uncorrelated with maternal genotypes) did not appear to affect population outcrossing estimates in the simulations. Heterogeneity G-tests and Spearman rank tests showed that pollen pool heterogeneity existed in the two natural populations examined; however, it did not have a major effect on population outcrossing estimates, since the consanguineous pollen pool detected was probably a relatively minor component of the outcross pollen pool in both populations. In addition, heterogeneity G-tests were found to be not sensitive in detecting pollen pool heterogeneity caused by consanguineous pollen pool.

  3. Comparison of lodgepole and jack pine resin chemistry: implications for range expansion by the mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae

    Full Text Available The mountain pine beetle, Dendroctonus ponderosae, is a significant pest of lodgepole pine in British Columbia (BC, where it has recently reached an unprecedented outbreak level. Although it is native to western North America, the beetle can now be viewed as a native invasive because for the first time in recorded history it has begun to reproduce in native jack pine stands within the North American boreal forest. The ability of jack pine trees to defend themselves against mass attack and their suitability for brood success will play a major role in the success of this insect in a putatively new geographic range and host. Lodgepole and jack pine were sampled along a transect extending from the beetle’s historic range (central BC to the newly invaded area east of the Rocky Mountains in north-central Alberta (AB in Canada for constitutive phloem resin terpene levels. In addition, two populations of lodgepole pine (BC and one population of jack pine (AB were sampled for levels of induced phloem terpenes. Phloem resin terpenes were identified and quantified using gas chromatography. Significant differences were found in constitutive levels of terpenes between the two species of pine. Constitutive α-pinene levels – a precursor in the biosynthesis of components of the aggregation and antiaggregation pheromones of mountain pine beetle – were significantly higher in jack pine. However, lower constitutive levels of compounds known to be toxic to bark beetles, e.g., 3-carene, in jack pine suggests that this species could be poorly defended. Differences in wounding-induced responses for phloem accumulation of five major terpenes were found between the two populations of lodgepole pine and between lodgepole and jack pine. The mountain pine beetle will face a different constitutive and induced phloem resin terpene environment when locating and colonizing jack pine in its new geographic range, and this may play a significant role in the ability of the

    Full Text Available In central Canada, long fire history reconstructions are rare. In a context where both anthropogenic and climate influences on fire regime have changed, Parks Canada has a mandate to maintain ecological integrity. Here we present a fire history derived from fire-scarred jack pine (Pinus banksiana Lamb. trees growing at their southern distribution limit in Riding Mountain National Park (RMNP. In Lake Katherine Fire Management Unit (LKFMU, a subregion within the park, fire history was reconstructed from archival records, tree-ring records, and charcoal in lake sediment. From about 1450 to 1850 common era (CE the fire return intervals varied from 37 to 125 years, according to models. During the period 1864–1930 the study area burned frequently (Weibull Mean Fire Intervals between 2.66 and 5.62 years; this period coincided with the end of First Nations occupation and the start of European settlement. Major recruitment pulses were associated with the stand-replacing 1864 and 1894 fires. This period nevertheless corresponded to a reduction in charcoal accumulation. The current fire-free period in LKFMU (1930–today coincides with RMNP establishment, exclusion of First Nations land use and increased fire suppression. Charcoal accumulation further decreased during this period. In the absence of fire, jack pine exclusion in LKFMU is foreseeable and the use of prescribed burning is advocated to conserve this protected jack pine ecosystem, at the southern margins of its range, and in the face of potential climate change.

    Full Text Available INTRODUCTION: There is little data concerning the ability of Eurycoma longifolia Jack (EL to reverse the inhibitory effects of estrogen on testosterone production and spermatogenesis. The aim of the present study was to determine the effect of EL on testicular histology and sperm count in estrogen-treated male rats. METHODS: Adult male Sprague-Dawley rats weighing 200-250 g were divided into four groups of six rats each. Group A (control was given solvent in the same manner as the treated groups were given EL. Group B was treated with EL (8 mg/kg body weight orally. Group C was treated with estradiol (E2 (intramuscular dose of 500 μg/kg body weight, and group D received a combined treatment of oral EL and intramuscular E2. After fourteen consecutive days of treatment, rats from all groups were sacrificed and subjected to spermatogenic and epididymal sperm cell counts. RESULTS: The spermatogenic cell count in the E2-treated group was significantly decreased as compared to the control (p < 0.05 and EL+E2-treated groups (p < 0.05. A similar finding was found for the epididymal sperm count; the E2-treated group had a significant decrease in the count compared to the control (p < 0.05 and EL+E2-treated groups (p < 0.05. Rats that were treated with EL alone exhibited significantly higher sperm counts and sperm motility when compared to the control group (p < 0.05. CONCLUSIONS: EL extract acts as a potential agent for reversing the effects of estrogen by increasing spermatogenesis and sperm counts in rats after fourteen consecutive days of treatment.

    Full Text Available Green Jacks, Caranx caballus, are distributed along the Eastern Pacific coast. In Panama, C. caballus was heavily fished around Las Perlas Archipelago to sustain local markets until 2007, when the archipelago was declared a marine protected area. This first study in Panama, analyzed a sample of 4 990 individuals from Las Perlas, obtained monthly from June 2005 to June 2006, from landings at the central fish market. Average total length was 36.1±6.4cm and optimum length 38.9cm. Approximately 68% of fish lengths were within ±10% of the optimal length but only six (15% were considered mega-spawners. The von Bertalanffy parameters describe a long-lived and fast growing species, while mortality rates revealed that C. caballus is under high fishing pressure. Standard length at which half of the population is mature was 38.8cm, and the size at which individuals matured massively, 33cm. Only 10-13% of the fish were immature. C. caballus reproduces two to three times per year, with peaks in December, April, and probably September, and recruits to the population at least twice per year. Catch per unit effort (CPUE was best predicted by minimum annual values of the Multivariate ENSO/ LNSO Index (MEI (R²=0.54. Results show that C. caballus in Pacific Panama is overfished. We recommend the raising of the minimum capture/landing size of this species in order to increase the proportion of megaspawners in the population and guarantee the sustainability of this resource.

    The purpose of this study is to predict spatial distributions of snow properties important to the hydrology and the remote sensing signatures of the boreal ecosystem. This study is part of the Boreal Ecosystems Atmosphere Study (BOREAS) of central Saskatchewan and northern Manitoba. Forested environments provide unique problems for snow cover process modeling due to the complex interactions among snow, energy transfer, and trees. These problems are approached by coupling a modified snow process model with a model of radiative interactions with forest canopies. Additionally, a tree well model describes the influence of individual trees on snow distribution on the ground. The snow process and energy budget model calculates energy exchange at the snow surface, in-pack snow processes, melting and liquid water flow, heat conduction, and vapor diffusion. The surface radiation model provides input on the radiation receipt at the snow surface for model runs in the jack pine forest. Field data consisted of measured meteorological parameters above and within the canopy, spatial variability of snow properties, and variations of incoming solar irradiance beneath the forest canopy. Results show that the area beneath tree canopies accumulated 60% of the snow accumulated in forest openings. Peak solar irradiance on the snow cover was less than one half that measured above the canopy. Model runs are compared between the open and the forested sites and show the open area ablating four days before areas beneath the canopy and eight days before forest openings and compare favorably with measured data. Physically based modeling of snow ablation was successful at the forested site and nearby open area.

    The aims of this study were (1) to evaluate motility parameters of donkey jack (jack; Equus asinus) semen cryopreserved in INRA-96 (INRA; IMV Technologies, France, 2% egg-yolk enriched) using either glycerol (GLY) or ethylene glycol (EG) as a cryoprotector; (2) to compare in vitro the postthaw re-extension with homologous seminal plasma (SPL) or INRA; (3) to compare fertility in donkey jennies (jennies; Equus asinus) timed artificially inseminated with jack semen cryopreserved using GLY or EG, re-extended with INRA; (4) to compare fertility in jennies timed artificially inseminated with jack semen cryopreserved using GLY re-extended with SPL, INRA, or not re-extended (NN); and (5) to describe some preliminary results of the inflammatory uterine response postbreeding. Semen from two jacks was collected and frozen in an INRA-2% egg yolk extender added of either 2.2% GLY or 1.4% EG. Postthaw motility was evaluated by a computer-assisted motility analyzer. Uterine inflammatory response and fertility were evaluated after artificial insemination (AI) of 13 jennies with frozen-thawed semen, either further extended with INRA (Group GLY-INRA, 13 cycles, and EG-INRA, 8 cycles), or with SPL (Group GLY-SPL, 13 cycles), or not re-extended (GLY-NN, 5 cycles). In each cycle, jennies were bred twice with 500 × 10(6) sperm cells (250 × 10(6) from each jack), at fixed times after induction of ovulation, and uterus was flushed at 6 and 10 h after first and second breeding, respectively. Cells in the recovered fluid were counted and distinguished as polymorphonuclear neutrophils (PMN) or other cell types. Total and progressive motility did not differ between cryoprotectants, but were higher when semen samples were re-extended in INRA, compared with SPL (P < 0.05). Pregnancy was diagnosed by transrectal palpation and ultrasonography examinations at 14 and 16 days postovulation. In 7/13 (53.8%) jennies and 12/39 (30.4%) cycles postbreeding intrauterine fluid accumulation was observed

    Pathogens infect their host and hijack the host machinery to produce more progeny pathogens. Obligate intracellular pathogens, in particular, require resources of the host to replicate. Therefore, infections by these pathogens lead to alterations in the metabolism of the host, shifting in favor of pathogen protein production. Some computational identification of mechanisms of host-pathogen interactions have been proposed, but it seems the problem has yet to be approached from the metabolite-hijacking angle. We propose a novel computational framework, Hi-Jack, for inferring pathway-based interactions between a host and a pathogen that relies on the idea of metabolite hijacking. Hi-Jack searches metabolic network data from hosts and pathogens, and identifies candidate reactions where hijacking occurs. A novel scoring function ranks candidate hijacked reactions and identifies pathways in the host that interact with pathways in the pathogen, as well as the associated frequent hijacked metabolites. We also describe host-pathogen interaction principles that can be used in the future for subsequent studies. Our case study on Mycobacterium tuberculosis (Mtb) revealed pathways in human-e.g. carbohydrate metabolism, lipids metabolism and pathways related to amino acids metabolism-that are likely to be hijacked by the pathogen. In addition, we report interesting potential pathway interconnections between human and Mtb such as linkage of human fatty acid biosynthesis with Mtb biosynthesis of unsaturated fatty acids, or linkage of human pentose phosphate pathway with lipopolysaccharide biosynthesis in Mtb.

  14. Jack-and-master trait responses to elevated CO2 and N: a comparison of native and introduced Phragmites australis.

    Directory of Open Access Journals (Sweden)

    Thomas J Mozdzer

    Full Text Available Global change is predicted to promote plant invasions world-wide, reducing biodiversity and ecosystem function. Phenotypic plasticity may influence the ability of introduced plant species to invade and dominate extant communities. However, interpreting differences in plasticity can be confounded by phylogenetic differences in morphology and physiology. Here we present a novel case investigating the role of fitness trait values and phenotypic plasticity to global change factors between conspecific lineages of Phragmites australis. We hypothesized that due to observed differences in the competitive success of North American-native and Eurasian-introduced P. australis genotypes, Eurasian-introduced P. australis would exhibit greater fitness in response to global change factors. Plasticity and plant performance to ambient and predicted levels of carbon dioxide and nitrogen pollution were investigated to understand how invasion pressure may change in North America under a realistic global change scenario. We found that the introduced Eurasian genotype expressed greater mean trait values in nearly every ecophysiological trait measured--aboveground and belowground--to elevated CO(2 and nitrogen, outperforming the native North American conspecific by a factor of two to three under every global change scenario. This response is consistent with "jack and master" phenotypic plasticity. We suggest that differences in plant nitrogen productivity, specific leaf area, belowground biomass allocation, and inherently higher relative growth rate are the plant traits that may enhance invasion of Eurasian Phragmites in North America. Given the high degree of genotypic variability within this species, and our limited number of genotypes, our results must be interpreted cautiously. Our study is the first to demonstrate the potential importance of jack-and-master phenotypic plasticity in plant invasions when facing imminent global change conditions. We suggest that

    From the beginning of human civilization, sexuality has been controlled by morals and laws. Using the example of Jack the Ripper, the authors present the significant and very serious problem of violence against women in the aspect of crime detection and forensic sexuology. According to Lernell [1], sex crimes are defined as "such types of sexuality-related human behaviors (including their consequences) that are forbidden by law" [2]. Such crimes encompass sex murders. Criminal behaviors of a sexual nature are perpetrated by representatives of all social strata.

    2017-01-01

    Simple Summary The identity of Jack the Ripper remains one of the greatest unsolved crime mysteries in history. Jack was notorious both for the brutality of his murders and also for his habit of stealing organs from his victims. His speed and skill in doing so, in conditions of poor light and haste, fueled theories he was a surgeon. However, re-examination of a mortuary sketch from one of his victims has revealed several key aspects that strongly suggest he had no professional surgical training. Instead, the technique used was more consistent with that of a slaughterhouse worker. There were many small-scale slaughterhouses in East London in the 1880s, within which conditions were harsh for animals and workers alike. The brutalizing effects of such work only add to concerns highlighted by modern research that those who commit violence on animals are more likely to target people. Modern slaughterhouses are more humane in some ways but more desensitizing in others, and sociological research has indicated that communities with slaughterhouses are more likely to experience the most violent of crimes. The implications for modern animal slaughtering, and our social reliance on slaughterhouses, are explored. Abstract Hundreds of theories exist concerning the identity of “Jack the Ripper”. His propensity for anatomical dissection with a knife—and in particular the rapid location and removal of specific organs—led some to speculate that he must have been surgically trained. However, re-examination of a mortuary sketch of one of his victims has revealed several aspects of incisional technique highly inconsistent with professional surgical training. Related discrepancies are also apparent in the language used within the only letter from Jack considered to be probably authentic. The techniques he used to dispatch his victims and retrieve their organs were, however, highly consistent with techniques used within the slaughterhouses of the day. East London in the 1880s had

    In the late spring or early summer of 2012, a flood emanated from a small moraine-dammed lake on the northeast flank of Three Fingered Jack in the Mount Jefferson Wilderness. Channel erosion or slope collapse breached the natural dam of the lake, leading to a sudden lowering of lake level by 2.8 m and discharge of 12,700 cubic meters (m3) of water. The resulting debris flow formed a bouldery deposit extending about 0.35 km downslope.

    Historical data show that outbreaks of the tree killing mountain pine beetle are often preceded by periods of drought. Global climate change impacts drought frequency and severity and is implicated in the range expansion of the mountain pine beetle into formerly unsuitable habitats. Its expanded range has recently reached the lodgepole × jack pine hybrid zone in central Alberta, Canada, which could act as a transition from its historical lodgepole pine host to a jack pine host present in the boreal forest. This field study tested the effects of water limitation on chemical defenses of mature trees against mountain pine beetle-associated microorganisms and on beetle brood success in lodgepole × jack pine hybrid trees. Tree chemical defenses as measured by monoterpene emission from tree boles and monoterpene concentration in needles were greater in trees that experienced water deficit compared to well-watered trees. Myrcene was identified as specific defensive compound, since it significantly increased upon inoculation with dead mountain pine beetles. Beetles reared in bolts from trees that experienced water deficit emerged with a higher fat content, demonstrating for the first time experimentally that drought conditions benefit mountain pine beetles. Further, our study demonstrated that volatile chemical emission from tree boles and phloem chemistry place the hybrid tree chemotype in-between lodgepole pine and jack pine, which might facilitate the host shift from lodgepole pine to jack pine.

    Clinical performance and safety of two percutaneous vertebral cement augmentation (VA) procedures (SpineJack® and Kyphx Xpander® balloon) were compared in patients with osteoporotic compression fractures. Both techniques were safe, efficient, and led to a rapid and marked improvement in clinical signs; nevertheless, SpineJack showed better restoration of vertebral heights and angles, maintained over time. In patients with osteoporotic vertebral compression fractures (VCFs), both SpineJack® (SJ) and balloon kyphoplasty (BKP) led to a rapid and marked improvement in clinical signs. This pilot, monocentric, investigator-initiated, prospective study aimed to compare two percutaneous vertebral augmentation procedures in the painful osteoporotic VCF treatment. Thirty patients were randomized to receive SJ (n = 15) or BKP (n = 15).

    The association between patterns of pigmentation and deafness in the dog has a long-documented history, with reports dating back over one hundred years. Long suspected of having a genetic basis, the search for loci with a pronounced influence in the expression of hearing loss in the dog has yet to be successful. No studies in the dog to date have found a possible influence of a specific colour locus associated with deafness. The present study is intended to evaluate the heritability of deafness in the Jack Russell Terrier (JRT), characterize the mode of inheritance, and evaluate the existence of a sex, coat colour, or coat texture influence on the expression of sensorineural deafness. The estimation of heritability of deafness in the JRT was 0.22 when deafness was considered a binary (normal/deaf) trait and 0.31 when deafness was considered a three-category (normal/unilateral/bilateral deafness). The influence of coat colour in the incidence of JRT deafness was statistically significant, indicating that dogs with more white are more likely to be deaf. The influence of sex or coat texture was not statistically significant in the incidence of JRT deafness. Complex segregation analysis revealed a model of a single locus with a large effect on the binary measure of hearing loss is not supported. This is the first attempt, to our knowledge, to characterize a genetic component responsible for deafness in the JRT. The heritability of deafness in the JRT was found to be 0.22 and 0.31 considering deafness to be a two-category or three-category trait, respectively. There appears to be an influence of coat colour on the expression of deafness. In an attempt to characterize the mode of inheritance of deafness in the JRT, a model of a single locus with a large effect on hearing loss is not supported with this data. Further study is needed to determine if a single locus may be influencing deafness in the JRT. While the absence of a clear mode of inheritance complicates genetic

    In the thirty years since John (Jack) Eddy’s work on the Big Horn Medicine Wheel, attention to the astronomy of medicine wheels went from high to low, with the lowest moment occurring during the ”welcome” talk of the Oxford IX International Archaeoastronomy (ISAAC) conference in Lima, Peru in 2011 when the wall-size projected image of the Big Horn Wheel carried a thick black “X” across its face. The alignments proposed by Eddy in 1974 and by Robinson in the 1980s have been reviewed and analyzed at the Wheel on Medicine Mountain in situ under bitter cold, clear dark nights at 10,000 feet altitude. Research was conducted using naked eye skywatching, transit surveying, and a Meade Cassegraine 8” electronic telescope. Along with this “review” of 20th century research, new research was conducted Wheel causing the second decade of the 21st century to bring new physical evidence and historical information for consideration.New research at the Big Horn Medicine Wheel gives evidence that the Wheel “mirrors” the night and daytime sky by creating a sky “grid” by its design made of basement and surface stones. The Wheel’s stone design mirrors the precession of the equinoxes by showing positions of all major pole stars over the full precessional cycle. Its twenty-eight sections are useful in the same way the twenty-eight sectioned Stations of the Moon star charts were useful in ancient and historical times. This manner of dividing the sky for tracking celestial objects holds celestial markers in constant position over millennia. This occurs because the Wheel’s center represents the Sun’ ecliptic north pole. Star charts that use the ecliptic pole do not need constant mathematical computation to keep up with current declinations and right ascensions. The Wheel’s twenty-eight sectioned sky chart keeps the same Dec and RA for celestial positions for thousands of years and will more quickly alert the observer to changes due to proper motion than will

    In our previous study, Rhizoma Coptidis extract was found to exert more potent inhibitory effect than its major component berberine towards urease from Helicobacter pylori (HPU) and jack bean (JBU). In continuation of our work, the present study was designed to further comparatively investigate the urease inhibitory activities of five major protoberberine alkaloids in Rhizoma Coptidis, namely berberine, palmatine, coptisine, epiberberine, jateorhizine to identify the bioactive constituent, and illuminate the potential mechanism of action. Results indicated that the five protoberberine alkaloids acted as concentration-dependent inactivators of urease with IC50 values ranging between 3.0 and 5087μM for HPU and 2.3->10,000μM for JBU, respectively. Notably, epiberberine (EB) was found to be the most potent inhibitor against both ureases with IC50 values of 3.0±0.01μM for HPU and 2.3±0.01μM for JBU, which was more effective than the standard urease inhibitor, acetohydroxamic acid (83±0.01μM for HPU and 22±0.01μM for JBU, respectively). Further kinetic analysis revealed that the type of EB inhibition against HPU was slow-binding and uncompetitive, with Ki of 10.6±0.01μM, while slow-binding and competitive against JBU with Ki of 4.6±0.01μM. Addition of thiol reagents, such as l-cysteine, glutathione and dithiothreitol, significantly abolished the inhibition, while Ni2+ competitive inhibitors, boric acid and sodium fluoride, synergetically inhibited urease with EB, indicating the obligatory role of the active site sulfhydryl group for the inhibition. In addition, binding of EB with the urease proved to be reversible, as about 65% and 90% enzymatic activity of HPU and JBU, respectively, could be restored by dithiothreitol application. These findings highlighted the potential role of Rhizoma Coptidis protoberberine alkaloids, especially EB, as a lead urease inhibitor in the treatment of diseases associated with ureolytic bacteria. Thus, EB had good potential

    Full Text Available Abstract Background The association between patterns of pigmentation and deafness in the dog has a long-documented history, with reports dating back over one hundred years. Long suspected of having a genetic basis, the search for loci with a pronounced influence in the expression of hearing loss in the dog has yet to be successful. No studies in the dog to date have found a possible influence of a specific colour locus associated with deafness. The present study is intended to evaluate the heritability of deafness in the Jack Russell Terrier (JRT, characterize the mode of inheritance, and evaluate the existence of a sex, coat colour, or coat texture influence on the expression of sensorineural deafness. Results The estimation of heritability of deafness in the JRT was 0.22 when deafness was considered a binary (normal/deaf trait and 0.31 when deafness was considered a three-category (normal/unilateral/bilateral deafness. The influence of coat colour in the incidence of JRT deafness was statistically significant, indicating that dogs with more white are more likely to be deaf. The influence of sex or coat texture was not statistically significant in the incidence of JRT deafness. Complex segregation analysis revealed a model of a single locus with a large effect on the binary measure of hearing loss is not supported. Conclusion This is the first attempt, to our knowledge, to characterize a genetic component responsible for deafness in the JRT. The heritability of deafness in the JRT was found to be 0.22 and 0.31 considering deafness to be a two-category or three-category trait, respectively. There appears to be an influence of coat colour on the expression of deafness. In an attempt to characterize the mode of inheritance of deafness in the JRT, a model of a single locus with a large effect on hearing loss is not supported with this data. Further study is needed to determine if a single locus may be influencing deafness in the JRT. While the

    The Australian wolf spider (Lycosidae Sundevall, 1833) genus Tasmanicosa Roewer, 1959 with Lycosa tasmanica Hogg, 1905 as type species is revised to include 14 species: T. godeffroyi (L. Koch, 1865), comb. nov. (= Lycosa tasmanica Hogg, 1905, syn. nov.; = Lycosa zualella Strand, 1907, syn. nov.; = Lycosa woodwardi Simon, 1909, syn. nov.); T. fulgor sp. nov.; T. gilberta (Hogg, 1905) comb. nov.; T. harmsi sp. nov.; T. hughjackmani sp. nov.; T. kochorum sp. nov.; T. leuckartii (Thorell, 1870), comb. nov. (= Lycosa molyneuxi Hogg, 1905, syn. nov.); T. musgravei (McKay, 1974) comb. nov.; T. phyllis (Hogg, 1905) comb. nov. (= Lycosa stirlingae Hogg, 1905, syn. nov.); T. ramosa (L. Koch, 1877), comb. nov.; T. salmo sp. nov.; T. semicincta (L. Koch, 1877) comb. nov.; T. stella sp. nov.; and T. subrufa (Karsch, 1878) comb. nov. Within the Australian wolf spider fauna, the genus Tasmanicosa can be diagnosed by the distinct pattern of radiating light and dark lines forming a "Union-Jack" pattern on the carapace. Male pedipalp morphology identifies the genus as part of the subfamily Lycosinae Sundevall, 1833 due to the presence of a transverse tegular apophysis with dorsal groove guiding the embolus during copulation. However, genital morphology is variable and a synapomorphy based on male pedipalp or female epigyne morphology could not be identified. Members of Tasmanicosa are comparatively large spiders (body length ca. 12-30 mm), that build a shallow burrow, which is sometimes covered with a flimsy trapdoor. Species of Tasmanicosa are largely a Bassian faunal element with preference for open woodlands and/or floodplains, although some species can be found into the semi-arid Australian interior. Two Australian wolf spider species may represent Tasmanicosa based on their original descriptions, but due to immature types in combination with the somatic similarities of all Tasmanicosa species, cannot be identified with certainty. They are therefore considered nomina dubia

    Hundreds of theories exist concerning the identity of "Jack the Ripper". His propensity for anatomical dissection with a knife-and in particular the rapid location and removal of specific organs-led some to speculate that he must have been surgically trained. However, re-examination of a mortuary sketch of one of his victims has revealed several aspects of incisional technique highly inconsistent with professional surgical training. Related discrepancies are also apparent in the language used within the only letter from Jack considered to be probably authentic. The techniques he used to dispatch his victims and retrieve their organs were, however, highly consistent with techniques used within the slaughterhouses of the day. East London in the 1880s had a large number of small-scale slaughterhouses, within which conditions for both animals and workers were exceedingly harsh. Modern sociological research has highlighted the clear links between the infliction of violence on animals and that inflicted on humans, as well as increased risks of violent crimes in communities surrounding slaughterhouses. Conditions within modern slaughterhouses are more humane in some ways but more desensitising in others. The implications for modern animal slaughtering, and our social reliance on slaughterhouses, are explored.

    Full Text Available Aim: To investigate various biochemical components of seminal plasma in Marwari stallions and Poitou Jacks and to find out their correlation with that of the seminal characteristics. Materials and Methods: In this study, semen was collected from six Marwari stallions and six Poitou jacks aged from 4 to 6 years and with known fertility status. The semen collection from the stallions were collected during the breeding season, i.e., between the months of April and June. From the collected semen ejaculates, we estimated the values of some biochemical components, viz., total protein content, total lipid content, and enzymes such as glutamic pyruvic transaminase (GPT, glutamic oxaloacetic transaminase (GOT, alkaline phosphatase (ALP, acid phosphatase (ACP, and lactate dehydrogenase (LDH as well as concentrations of glucose, cholesterol, total calcium (Ca, and phosphorus (P and correlations among different seminal parameters were statistically examined using the Pearson correlation coefficient. Results: In this study, we found positive correlations between semen volume as well as sperm concentration and GOT, GPT, ALP and ACP for both the group stallions. Significant correlation between motility and glucose, GOT and GPT could be an indication for their role metabolism and protection against free radicals to the spermatozoa. Conclusion: Based on the results, it is concluded that there is a positive correlation between some biochemical values such as glucose, Ca, ALP, and LDH and seminal parameters which play a key role in capacitation and onward movement of the spermatozoa.

    Full Text Available Heavy lift jack-up vessels (HLJV are used for the installation of components of large offshore wind farms. A systematic FE-analysis is presented for the HLJV THOR (owned by Hochtief Infrastructure GmbH under extreme weather conditions. A parametric finite element (FE model and analysis are developed by using ANSYS-APDL programming environment. The analysis contains static and dynamic nonlinear FE-calculations, which are carried out according to the relevant standards (ISO 19905 for in-place analyses of jack-up vessels. Besides strategies of model abstraction, a guide for the determination of the relevant loads is given. In order to calculate the dynamic loads, single degree of freedom (SDOF analogy and dynamic nonlinear FE-calculations are used. As a result of detailed determination of dynamic loads and consideration of soil properties by spring elements, the used capacities are able to be reduced by 28 %. This provides for significant improvement of the environmental restrictions of the HLJV THOR for the considered load scenario.

    Minimally invasive treatment of vertebral fractures is basically characterized by cement augmentation. Using the combination of a permanent implant plus cement, it is now conceivable that the amount of cement can be reduced and so this augmentation could be an attractive opportunity for use in traumatic fractures in young and middle-aged patients. The objective of this study was to determine the smallest volume of cement necessary to stabilize fractured vertebrae comparing the SpineJack system to the gold standard, balloon kyphoplasty. 36 fresh frozen human cadaveric vertebral bodies (T11-L3) were utilized. After creating typical compression wedge fractures (AO A1.2.1), the vertebral bodies were reduced by SpineJack (n=18) or kyphoplasty (n=18) under preload (100N). Subsequently, different amounts of bone cement (10%, 16% or 30% of the vertebral body volume) were inserted. Finally, static and dynamic biomechanical tests were performed. Following augmentation and fatigue tests, vertebrae treated with SpineJack did not show any significant loss of intraoperative height gain, in contrast to kyphoplasty. In the 10% and 16%-group the height restoration expressed as a percentage of the initial height was significantly increased with the SpineJack (>300%). Intraoperative SpineJack could preserve the maximum height gain (mean 1% height loss) better than kyphoplasty (mean 16% height loss). In traumatic wedge fractures it is possible to reduce the amount of cement to 10% of the vertebral body volume when SpineJack is used without compromising the reposition height after reduction, in contrast to kyphoplasty that needs a 30% cement volume.

    Osteoporotic vertebral compression fracture is a serious complication of osteoporosis. Various vertebral kyphoplasty surgeries, which have their own unique features, are commonly used for osteoporotic vertebral compression fracture. Based on the anatomic property of the thoracolumbar vertebral pedicle that its horizontal diameter is twice that of the vertical diameter, we designed Jack vertebral dilator for better restoration of the vertebral height by manipulating the mechanical force. A total of 218 patients (236 vertebrae) with osteoporotic vertebral compression fracture were treated with Jack vertebral dilator. Surgery was successfully completed in all cases, and all the 218 patients were followed up for an average of 14.2 months (range 3 to 30 months). Bone cement leakage occurred in 12 cases, but no symptoms were reported. No other complications were noticed. The VAS scores were 8.2 ± 1.3, 1.7 ± 0.9, and 1.8 ± 0.8 and the ODI was 78.2 ± 13.3 %, 18.5 ± 7.3 %, and 20.9 ± 6.8 % before surgery and 1 week after surgery and at the final follow-up, respectively. The anterior vertebral body height was 19.3 ± 3.2, 25.1 ± 2.6, and 24.9 ± 2.6 mm and the central vertebral body height was 18.7 ± 3.0, 24.8 ± 3.0, and 24.5 ± 2.9 mm before surgery and 1 week after surgery and at the final follow-up, respectively. Cobb angle was 16.2° ± 6.6°, 8.1° ± 5.6°, and 8.5° ± 5.6° before surgery and 1 week after surgery and at the final follow-up, respectively. Jack vertebral dilator kyphoplasty for osteoporotic vertebral compression fracture is safe, feasible, and effective and has the prospect of further broad application in the future.

    Recently, Aker Solutions delivered a movable chain jack system to PETROBRAS's P58/P62 FPSOs and a movable windlass system to ENI's Goliat FPSO. This paper highlights the main differences between the two systems and when it is beneficial to employ movable systems. There are many parameters to consider in determining which system to use - also a traditional system involving a single winch or chain jack per mooring line may in many cases be preferred. The movable chain jack concept is designed to operate multiple mooring lines within the same cluster. A single chain jack is lifted by a skidding gantry and moved to the next mooring line and so forth. Installation and messenger chains are moved using a large sliding chain locker allowing for later offloading of the surplus chain. The movable windlass system is also designed to operate multiple mooring lines within the same cluster. However, in this case the winch is rotary and can operate via electric or hydraulic power. One of the main considerations is to move the windlass and keep the mooring lines intact without cutting them. (author)

    In vertebral compression fractures, the potential of kyphoplasty for restoring vertebral height is limited by the loss of restored height that occurs when the balloon is deflated and removed. SpineJack(®) is also inserted percutaneously but is then left within the vertebral body after its expansion to reduce the fracture, thus avoiding loss of correction before the injection of cement. SpineJack(®) was used in 77 patients to treat 83 recent VCFs (55.4% at L1-L2) due to trauma (59.7%) or osteoporosis (40.3%). Three (3.9%) complications were recorded, but none was related to SpineJack(®): there was one case each of symptomatic cement leakage along a secondary pedicular fracture line; infection; and incipient device migration at the beginning of the learning curve. The rate of adjacent fractures was only 2.6%. The 5-year outcomes demonstrate that SpineJack(®) provides both immediate and long-term benefits in terms of pain relief, functional recovery, and maintenance of vertebral height restoration.

    Full Text Available Eurycomanone and eurycomanol are two quassinoids from the roots of Eurycoma longifolia Jack. The aim of this study was to assess the bioactivity of these compounds in Jurkat and K562 human leukemia cell models compared to peripheral blood mononuclear cells from healthy donors. Both eurycomanone and eurycomanol inhibited Jurkat and K562 cell viability and proliferation without affecting healthy cells. Interestingly, eurycomanone inhibited NF-κB signaling through inhibition of IκBα phosphorylation and upstream mitogen activated protein kinase (MAPK signaling, but not eurycomanol. In conclusion, both quassinoids present differential toxicity towards leukemia cells, and the presence of the α,β-unsaturated ketone in eurycomanone could be prerequisite for the NF-κB inhibition.

    The effectiveness of ectomycorrhizal inoculation at the tree nursery seedling production stage on growth and survival was examined in jack pine (Pinus banksiana) and white spruce (Picea glauca) planted in oil sands reclamation sites. The seedlings were inoculated with Hebeloma crustuliniforme strain # UAMH 5247, Suillus tomentosus strain # UAMH 6252, and Laccaria bicolor strain # UAMH 8232, as individual pure cultures and in combinations. These treatments were demonstrated to improve salinity resistance and water uptake in conifer seedlings. The field responses of seedlings to ectomycorrhizal inoculation varied between plant species, inoculation treatments, and measured parameters. Seedling inoculation resulted in higher ectomycorrhizal colonization rates compared with non-inoculated control, which had also a relatively small proportion of roots colonized by the nursery contaminant fungi identified as Amphinema byssoides and Thelephora americana. Seedling inoculation had overall a greater effect on relative height growth rates, dry biomass, and stem volumes in jack pine compared with white spruce. However, when examined after two growing seasons, inoculated white spruce seedlings showed up to 75% higher survival rates than non-inoculated controls. The persistence of inoculated fungi in roots of planted seedlings was examined at the end of the second growing season. Although the inoculation with H. crustuliniforme triggered growth responses, the fungus was not found in the roots of seedlings at the end of the second growing season suggesting a possibility that the observed growth-promoting effect of H. crustuliniforme may be transient. The results suggest that the inoculation of conifer seedlings with ectomycorrhizal fungi could potentially be carried out on a large scale in tree nurseries to benefit postplanting performance in oil sands reclamation sites. However, these practices should take into consideration the differences in responses between the different

  2. Hi-Jack: a novel computational framework for pathway-based inference of host–pathogen interactions

    2015-03-09

    Motivation: Pathogens infect their host and hijack the host machinery to produce more progeny pathogens. Obligate intracellular pathogens, in particular, require resources of the host to replicate. Therefore, infections by these pathogens lead to alterations in the metabolism of the host, shifting in favor of pathogen protein production. Some computational identification of mechanisms of host-pathogen interactions have been proposed, but it seems the problem has yet to be approached from the metabolite-hijacking angle. Results: We propose a novel computational framework, Hi-Jack, for inferring pathway-based interactions between a host and a pathogen that relies on the idea of metabolite hijacking. Hi-Jack searches metabolic network data from hosts and pathogens, and identifies candidate reactions where hijacking occurs. A novel scoring function ranks candidate hijacked reactions and identifies pathways in the host that interact with pathways in the pathogen, as well as the associated frequent hijacked metabolites. We also describe host-pathogen interaction principles that can be used in the future for subsequent studies. Our case study on Mycobacterium tuberculosis (Mtb) revealed pathways in human-e.g. carbohydrate metabolism, lipids metabolism and pathways related to amino acids metabolism-that are likely to be hijacked by the pathogen. In addition, we report interesting potential pathway interconnections between human and Mtb such as linkage of human fatty acid biosynthesis with Mtb biosynthesis of unsaturated fatty acids, or linkage of human pentose phosphate pathway with lipopolysaccharide biosynthesis in Mtb. © The Author 2015.

    2013-12-01

    Full Text Available Lipid damage evolution was analyzed in chilled Chilean jack mackerel (Trachurus murphyi previously treated with high hydrostatic pressure (HHP technology. Different pressure levels and pressure holding times were tested. In addition, fish corresponding to pre- and post-rigor mortis (RM stages were comparatively studied. Previous HHP treatment led to a marked lipid hydrolysis inhibition in chilled fish. Increasing the pressure level and pressure holding time led to a lower free fatty acid content, with the effect of pressure being more relevant. According to the analysis of different types of lipid oxidation indexes, no effect of the previous HHP treatment on the lipid oxidation development could be determined in chilled jack mackerel. Concerning the effect of the RM stage of raw fish, a higher primary and secondary lipid oxidation development was observed in fish corresponding to the post-RM condition throughout the chilled storage; although a definite effect on lipid hydrolysis could not be found.Se estudió la evolución de la alteración lipídica en jurel chileno (Trachurus murphyi refrigerado previamente tratado a altas presiones hidrostáticas (HHP. Se aplicaron distintos valores de presión y tiempo de presurización; asimismo, se analizó de forma comparativa la respuesta al proceso del pescado inicial en estados pre- y post-rigor mortis (RM. El tratamiento previo por HHP produjo inhibición de la hidrólisis lipídica en pescado refrigerado, siendo más intenso el efecto de la presión que el del tiempo de presurización. De acuerdo con el análisis de distintos índices de oxidación, no se concluyó un efecto determinante sobre la oxidación lipídica por parte del tratamiento previo de HHP. En relación al efecto del estado de RM del pescado inicial, se observó una oxidación primaria y secundaria mayor en jurel correspondiente a la condición post-RM durante la conservación en refrigeración; sin embargo, no se detectó un efecto

    Recent declines in productivity and tree survival have been widely observed in boreal forests. We used early warning signals (EWS) in tree ring data to anticipate premature mortality in jack pine (Pinus banksiana)—an extensive and dominant species occurring across the moisture-limited southern boreal forest in North America. We sampled tree rings from 113 living and 84 dead trees in three soil moisture regimes (subxeric, submesic, subhygric) in central Saskatchewan, Canada. We reconstructed annual increments of tree basal area to investigate (1) whether we could detect EWS related to mortality of individual trees, and (2) how water availability and tree growth history may explain the mortality warning signs. EWS were evident as punctuated changes in growth patterns prior to transition to an alternative state of reduced growth before dying. This transition was likely triggered by a combination of severe drought and insect outbreak. Higher moisture availability associated with a soil moisture gradient did not appear to reduce tree sensitivity to stress-induced mortality. Our results suggest tree rings offer considerable potential for detecting critical transitions in tree growth, which are linked to premature mortality.

    Tabat barito (Ficus deltoidea Jack) is a name given by Dayak Tribe who lived in Borneo-Kalimantan and it is belongs to the moraceae. Almost all of the parts of F. deltoidea plant is widely used as a medicinal property. The total flavonoid content (TFC) and antioxidant activity from cultivated and wild F. deltoidea leaves and stems extract were assessed. Total flavonoid content was estimated by using Aluminium chloride colorimetric method and expressed as catechin equivalents (mg CE g-1 extract) and the antioxidant activity by the DPPH (2,2-diphenyl-1-picryl hydrazyl) method. The content of total flavonoid of leaves and stems (430.77 and 371.80 µg CE mg-1 extract) of cultivated F. deltoidea were higher than in the wild leaves and stems (114.82 and 66.67 µg CE mg-1 extract). The IC50 of leaves extract of cultivated and wild F. deltoidea, based on the DPPH assay, has a strong antioxidant activity (34.19 and 39.31 µg mL-1 extract) as compared to stems extract. These results showed that the cultivated F. deltoidea are suitable source for medicinal properties and the leaves could be exploited as source of natural antioxidants.

    The Jack Rabbit (JR) field experiment, involving releases of one or two tons of pressurized liquefied chlorine and ammonia into a depression, took place in 2010 at Dugway Proving Ground, Utah, USA. The releases, of duration about 30 s from a short pipe at a height of 2m, were directed towards the ground. The dense two phase cloud was initially confined in a depression of 2 m depth and 50 m diameter. With wind speedsabout 1.5 m s(-1), the initial cloud was not well-confined in the depression and moved downwind. Formulas suggested by Briggs et al. in 1990 in this journal satisfactorily predict the time durations of confinement. Sensitivity runs with the SLAB dense gas model show that the effect of a long confinement on maximum downwind concentrations is strongest near the depression. The model-predicted and observed maximum 20 s chlorine concentrations agree within a factor of two most of the time, as long as the release times based on Briggs' theory are used.

    Helicobacter pylori (H. pylori) infection leads to different clinical and pathological outcomes in humans, including chronic gastritis, peptic ulcer disease and gastric neoplasia and even gastric cancer and its eradiation dependst upon multi-drug therapy. The most effective therapy is still unknown and prompts people to make great efforts to find better and more modern natural or synthetic anti-H. pylori agents. In this report 21 randomly selected herbal methanolic extracts were evaluated for their effect on inhibition of Jack-bean urease using the indophenol method as described by Weatherburn. The inhibition potency was measured by UV spectroscopy technique at 630 nm which attributes to released ammonium. Among these extracts, five showed potent inhibitory activities with IC50 ranges of 18-35 μg/mL. These plants are Matricaria disciforme (IC50:35 μg/mL), Nasturtium officinale (IC50:18 μg/mL), Punica granatum (IC50:30 μg/mL), Camelia sinensis (IC50:35 μg/mL), Citrus aurantifolia (IC50:28 μg/mL).

  16. White Anglo-Saxon hopes and black Americans' Atlantic dreams: Jack Johnson and the British boxing colour bar.

    Runstedtler, Theresa

    2010-01-01

    This article examines the controversy surrounding Jack Johnson's proposed world heavyweight title fight against the British champion Bombardier Billy Wells in London (1911). In juxtaposing African Americans' often glowing discussions of European tolerance with the actual white resistance the black champion faced in Britain, including the Home Office's eventual prohibition of the match, the article explores the period's transnational discourses of race and citizenship. Indeed, as white sportsmen on both sides of the Atlantic joined together in their search for a "White Hope" to unseat Johnson, the boxing ring became an important cultural arena for interracial debates over the political and social divisions between white citizens and nonwhite subjects. Although African Americans had high hopes for their hero's European sojourn, the British backlash against the Johnson-Wells match underscored the fact that their local experiences of racial oppression were just one facet of a much broader global problem. At the same time, the proposed prizefight also made the specter of interracial conflict in the colonies all the more tangible in the British capital, provoking public discussions about the merits of U.S. racial segregation, along with the need for white Anglo-Saxon solidarity around the world. Thus, this article not only exposes the underlying connections between American Jim Crow and the racialized fault lines of British imperialism, but it also traces the "tense and tender ties" linking U.S. and African American history with the new imperial history and postcolonial studies.

  17. Geohydrologic feasibility study of the Piceance Basin of Colorado for the potential applicability of Jack W. McIntyre`s patented gas/produced water separation process

    Geraghty & Miller, Inc. of Midland, Texas conducted geologic and hydrologic feasibility studies of the potential applicability of Jack McIntyre`s patented process for the recovery of natural gas from coalbed/sand formations in the Piceance Basin through literature surveys. Jack McIntyre`s tool separates produced water from gas and disposes of the water downhole into aquifers unused because of poor water quality, uneconomic lifting costs or poor aquifer deliverability. The beneficial aspects of this technology are two fold. The process increases the potential for recovering previously uneconomic gas resources by reducing produced water lifting, treatment and disposal costs. Of greater importance is the advantage of lessening the environmental impact of produced water by downhole disposal. Results from the survey indicate that research in the Piceance Basin includes studies of the geologic, hydrogeologic, conventional and unconventional recovery oil and gas technologies. Available information is mostly found centered upon the geology and hydrology for the Paleozoic and Mesozoic sediments. Lesser information is available on production technology because of the limited number of wells currently producing in the basin. Limited information is available on the baseline geochemistry of the coal/sand formation waters and that of the potential disposal zones. No determination was made of the compatibility of these waters. The study also indicates that water is often produced in variable quantities with gas from several gas productive formations which would indicate that there are potential applications for Jack McIntyre`s patented tool in the Piceance Basin.

    In 1998, an 8-mile reach of the Jacks Fork was included on Missouri?s list of impaired waters as required by Section 303(d) of the Federal Clean Water Act. The identified pollutant on the Jacks Fork was fecal coliform bacteria. Potential sources of fecal contamination to the Jacks Fork include a wastewater treatment plant; campground pit-toilet or septic-system effluent; a large commercial, cross-country horseback trail riding facility; canoeists, boaters, and tubers; and cows.The U.S. Geological Survey, in cooperation with the National Park Service, conducted a study to better understand the extent and sources of microbiological contamination within the Jacks Fork from Alley Spring to the mouth, which includes the 8-mile 303(d) reach. Identification of the sources would provide the National Park Service and the State of Missouri with the information needed to craft a solution of abatement, regulation, prevention, and mitigation with the end result being the removal of the Jacks Fork from the 303(d) list. Fifteen sites were sampled from November 1999 through December 2000. An additional site was sampled one time. Samples were collected mostly during base-flow conditions during a variety of nonrecreational and recreational season river uses. Samples were analyzed for selected fecal indicator bacteria, physical properties, nutrients, and wastewater organic compounds. During the sampling period, the whole-body-contact recreation standard for fecal coliform (200 colonies per 100 milliliters of sample) was exceeded at three sites on August 10, 2000, and also at one site on May 11, June 7, and October 3, 2000. Fecal coliform densities and instantaneous loads generally increased from background concentrations at the Eminence site, peaked about 2 river miles downstream, and then decreased until the most downstream site sampled. Generally, the largest densities and loads at sites downstream from Eminence not related to wet-weather flow were observed during a trail ride held

    Cable-in-conduit conductors (CICCs) for ITER magnets are subjected to fast changing magnetic fields during the plasma-operating scenario. In order to anticipate the limitations of conductors under the foreseen operating conditions, it is essential to have a better understanding of the stability margin of magnets. In the last decade ITER has launched a campaign for characterization of several types of NbTi and Nb3Sn CICCs comprising quench tests with a singular sine wave fast magnetic field pulse and relatively small amplitude. The stability tests, performed in the SULTAN facility, were reproduced and analyzed using two codes: JackPot-AC/DC, an electromagnetic-thermal numerical model for CICCs, developed at the University of Twente (van Lanen and Nijhuis 2010 Cryogenics 50 139-148) and multi-constant-model (MCM) (Turck and Zani 2010 Cryogenics 50 443-9), an analytical model for CICCs coupling losses. The outputs of both codes were combined with thermal, hydraulic and electric analysis of superconducting cables to predict the minimum quench energy (MQE) (Bottura et al 2000 Cryogenics 40 617-26). The experimental AC loss results were used to calibrate the JackPot and MCM models and to reproduce the energy deposited in the cable during an MQE test. The agreement between experiments and models confirm a good comprehension of the various CICCs thermal and electromagnetic phenomena. The differences between the analytical MCM and numerical JackPot approaches are discussed. The results provide a good basis for further investigation of CICC stability under plasma scenario conditions using magnetic field pulses with lower ramp rate and higher amplitude.

    Geraghty & Miller, Inc. of Midland, Texas conducted a geohydrologic study of the Michigan Basin to evaluate the applicability of Jack McIntyre`s patented process for gas recovery and water disposal in production wells. A review of available publications was conducted to identify, (1) natural gas reservoirs which generate large quantities of gas and water, and (2) underground injection zones for produced water. Research efforts were focused on unconventional natural gas formations. The Antrim Shale is a Devonian gas shale which produces gas and large quantities of water. Total 1992 production from 2,626 wells was 74,209,916 Mcf of gas and 25,795,334 bbl of water. The Middle Devonian Dundee Limestone is a major injection zone for produced water. ``Waterless completion`` wells have been completed in the Antrim Shale for gas recovery and in the Dundee Limestone for water disposal. Jack McIntyre`s patented process has potential application for the recovery of gas from the Antrim Shale and simultaneous injection of produced water into the Dundee Limestone.

    Doxorubicin (Dox) is known as anticancer drug commonly used for cancer treatment. Eurycoma longifolia Jack or Pasakbumi was reported to have chemopreventive effect. In cancer patients, there are some dysfunctions of blood parameter, therefore some hematologic tests are needed to monitor cancer patients. In this study, the effects of combination of ethanolic extract of E. longifolia Jack (EEE) and Dox on hematologic profiles were investigated in rats injected by DMBA. Rats were divided into eight groups. Group I was normal group; Group II, rats were treated with extract dose 100 mg/kgbw; Groups III, IV, V, VI, VII and VIII, rats were treated with Dox, DMBA, DMBA+Dox, DMBA+EEE, DMBA+Dox +EEE, and Dox+EEE, respectively. DMBA administration orally was conducted twice a week for 5 weeks. At 16th week of treatments, bloods were taken from orbitalis sinus for hematologicals profile (levels of Hb, erytrocyte, hematocrite, leukocyte, MCV, MCH, and differencial leucocyte count) measurements. These data were analyzed by one way ANOVA followed by LSD test. DMBA administration significantly decreased the hematological profiles compared to the normal group, except in lymphocyte level. Rats treated with extract and extract+Dox were able to increase the hematological profile compared to rats given by DMBA only. Based on these findings it can be concluded that the combination of EEE and Dox potentially increase hematological profile of rats given by DMBA.

    Full Text Available In ways comparable to the horrors of Hurricane Katrina and its aftermath in 2005, the series of yellow fever epidemics that devastated New Orleans through the nineteenth century were also the result, in part, of the city’s geographical position, its unforgiving climate, and the policies of interested parties; the fever’s awful death toll was likewise accompanied by a grotesque array of sights, sounds and smells. This article will focus upon Josh Russell’s 1999 novel Yellow Jack, which provides a complex portrait of the mid-nineteenth-century city, its fever epidemics, and its conflicting narratives. As well as providing an intense fictional encounter with a formative period in New Orleans’s history, Yellow Jack is a sophisticated study of the role of visual imagery in documenting such horrors, whose prose is steeped in the smells and sounds of the time and place. This article, then, will discuss this novel’s intense engagement with the various “senses” of a very particular Southern place.Dans un certain sens comparables à la tragédie et aux conséquences de l'ouragan Katrina en 2005, les séries d’épidémies de fièvre jaune qui dévastèrent La Nouvelle-Orléans au cours du XIXe siècle furent aussi — du moins partiellement — le résultat de la situation géographique de la ville, de son climat insupportable et de la politique des milieux intéressés; de manière semblable, la rage de cette fièvre ravageuse était accompagnée d’un ensemble grotesque d’images, de bruits et d’odeurs. Dans cet essai, je me limite au roman Yellow Jack de Josh Russell, qui, publié en 1999, trace le portrait complexe de cette ville du milieu du xixe siècle, de ses épidémies de fièvre et de ses récits contradictoires.

    The NBR seals are used in tribological systems because they are resistance to solvent, oil and fuel. This elastomer is used in the jack pump (oil pump unit-PETROBRAS), it is located in the stuffing box. It converts the rotational movement of an electric motor to a vertical reciprocating movement to drive the pump shaft, generating a tribological contact between the polished rod and the seal, avoiding oil leakage. In this work, was developed an experimental test rig to simulate the sealing conditions of the tribological pair polished rod-seal package for a oil pumping unit in a 1:1 scale. In the experimental part of this work were used several techniques as thermal history, Scanning Electron Microscope (SEM), hardness and mass losses analysis. The friction influence on the temperature was one of the most important effect caused by the contact. The SEM analyses and the hardness losses had evidenced the damage on the surface submitted to the contact. (author)

    Recent studies in streams and ponds have demonstrated that the distribution and biomass of aquatic organisms can be estimated by detection and quantification of environmental DNA (eDNA). In more open systems such as seas, it is not evident whether eDNA can represent the distribution and biomass of aquatic organisms because various environmental factors (e.g., water flow) are expected to affect eDNA distribution and concentration. To test the relationships between the distribution of fish and eDNA, we conducted a grid survey in Maizuru Bay, Sea of Japan, and sampled surface and bottom waters while monitoring biomass of the Japanese jack mackerel (Trachurus japonicus) using echo sounder technology. A linear model showed a high R2 value (0.665) without outlier data points, and the association between estimated eDNA concentrations from the surface water samples and echo intensity was significantly positive, suggesting that the estimated spatial variation in eDNA concentration can reflect the local biomass of the jack mackerel. We also found that a best-fit model included echo intensity obtained within 10–150 m from water sampling sites, indicating that the estimated eDNA concentration most likely reflects fish biomass within 150 m in the bay. Although eDNA from a wholesale fish market partially affected eDNA concentration, we conclude that eDNA generally provides a ‘snapshot’ of fish distribution and biomass in a large area. Further studies in which dynamics of eDNA under field conditions (e.g., patterns of release, degradation, and diffusion of eDNA) are taken into account will provide a better estimate of fish distribution and biomass based on eDNA.

  16. Evolution of Conifer Diterpene Synthases: Diterpene Resin Acid Biosynthesis in Lodgepole Pine and Jack Pine Involves Monofunctional and Bifunctional Diterpene Synthases1[W][OA

    Diterpene resin acids (DRAs) are major components of pine (Pinus spp.) oleoresin. They play critical roles in conifer defense against insects and pathogens and as a renewable resource for industrial bioproducts. The core structures of DRAs are formed in secondary (i.e. specialized) metabolism via cycloisomerization of geranylgeranyl diphosphate (GGPP) by diterpene synthases (diTPSs). Previously described gymnosperm diTPSs of DRA biosynthesis are bifunctional enzymes that catalyze the initial bicyclization of GGPP followed by rearrangement of a (+)-copalyl diphosphate intermediate at two discrete class II and class I active sites. In contrast, similar diterpenes of gibberellin primary (i.e. general) metabolism are produced by the consecutive activity of two monofunctional class II and class I diTPSs. Using high-throughput transcriptome sequencing, we discovered 11 diTPS from jack pine (Pinus banksiana) and lodgepole pine (Pinus contorta). Three of these were orthologous to known conifer bifunctional levopimaradiene/abietadiene synthases. Surprisingly, two sets of orthologous PbdiTPSs and PcdiTPSs were monofunctional class I enzymes that lacked functional class II active sites and converted (+)-copalyl diphosphate, but not GGPP, into isopimaradiene and pimaradiene as major products. Diterpene profiles and transcriptome sequences of lodgepole pine and jack pine are consistent with roles for these diTPSs in DRA biosynthesis. The monofunctional class I diTPSs of DRA biosynthesis form a new clade within the gymnosperm-specific TPS-d3 subfamily that evolved from bifunctional diTPS rather than monofunctional enzymes (TPS-c and TPS-e) of gibberellin metabolism. Homology modeling suggested alterations in the class I active site that may have contributed to their functional specialization relative to other conifer diTPSs. PMID:23370714

    The Ozark National Scenic Riverways (ONSR) is a narrow corridor that stretches for approximately 134 miles along the Current River and Jacks Fork in southern Missouri. Most of the water flowing in the Current River and Jacks Fork is discharged to the rivers from springs within the ONSR, and most of the recharge area of these springs is outside the ONSR. This report describes geohydrologic investigations and landscape characteristics of areas contributing water to springs and the Current River and Jacks Fork in the ONSR. The potentiometric-surface map of the study area for 2000-07 shows that the groundwater divide extends beyond the surface-water divide in some places, notably along Logan Creek and the northeastern part of the study area, indicating interbasin transfer of groundwater between surface-water basins. A low hydraulic gradient occurs in much of the upland area west of the Current River associated with areas of high sinkhole density, which indicates the presence of a network of subsurface karst conduits. The results of a low base-flow seepage run indicate that most of the discharge in the Current River and Jacks Fork was from identified springs, and a smaller amount was from tributaries whose discharge probably originated as spring discharge, or from springs or diffuse groundwater discharge in the streambed. Results of a temperature profile conducted on an 85-mile reach of the Current River indicate that the lowest average temperatures were within or downstream from inflows of springs. A mass-balance on heat calculation of the discharge of Bass Rock Spring, a previously undescribed spring, resulted in an estimated discharge of 34.1 cubic feet per second (ft3/s), making it the sixth largest spring in the Current River Basin. The 13 springs in the study area for which recharge areas have been estimated accounted for 82 percent (867 ft3/s of 1,060 ft3/s) of the discharge of the Current River at Big Spring during the 2006 seepage run.

    Full Text Available Pre-drilling was performed to reduce lateral earth pressure generated by pile foundation hydraulically jacked into expansive soil. Nineteen prestressed-precast spun concrete pile with diameter of 800 mm were penetrated into expansive soil up the depth of 40 m. Pre-drilling with diameter of 700 mm was carried out up to the depth of 12.5 m. Penetration loads required to install the piles, which was displayed on the built-in pressure panel, were recorded every 1 m interval. The load that was consisted of merely shaft friction was then used to find out the mobilized skin friction between pile shaft and its surrounding soils. The calculated mobilized skin friction was correlated to the value of Standard Penetration Test (NSPT and compared to Decourt formula. The result shows that skin friction calculated using Decourt formula relatively conservative compared to those determined from the records of field penetration. The upper bound of mobilized skin friction can be defined by modifying Decourt formula.

    Effects of ectomycorrhizal (ECM) fungus Suillus tomentosus on water transport properties were studied in jack pine (Pinus banksiana) seedlings. The hydraulic conductivity of root cortical cells (L(pc)) and of the whole root system (L(pr)) in ECM plants was higher by twofold to fourfold compared with the non-ECM seedlings. HgCl2 had a greater inhibitory effect on L(pc) in ECM compared with non-ECM seedlings, suggesting that the mercury-sensitive, aquaporin (AQP)-mediated water transport was largely responsible for the differences in L(pc) between the two groups of plants. L(pc) was rapidly and drastically reduced by the 50 mM NaCl treatment. However, in ECM plants, the initial decline in L(pc) was followed by a quick recovery to the pre-treatment level, while the reduction of L(pc) in non-ECM seedlings progressed over time. Treatments with fluoride reduced L(pc) by about twofold in non-ECM seedlings and caused smaller reductions of L(pc) in ECM plants. When either 2 mM KF or 2 mM NaF were added to the 50 mM NaCl treatment solution, the inhibitory effect of NaCl on L(pc) was rapidly reversed in both groups of plants. The results suggest that AQP-mediated water transport may be linked to the enhancement of salt stress resistance reported for ECM plants.

    Horizontal distribution patterns of jack mackerel Trachurus japonicus larvae were investigated extensively in the East China Sea (ECS) along the shelf-break region between 26° and 30°N during February-March based on fine-scale larval sampling in 2002 and 2003. A total of 2363 T. japonicus ranging from 1.2 to 12.4 mm body length (BL) were collected at 310 bongo net sampling stations, of which larvae closely with the direction of the Kuroshio Branch Current north of Taiwan (KBCNT) and the Kuroshio, respectively. Replicate sampling cruises at 2 week intervals were conducted in 2003, and the larval distribution pattern changed significantly between the sampling cruises, suggesting that the transport process fluctuates over relatively short periods in relation to oceanographic processes. The transport speed by the KBCNT was estimated to be 0.13-0.28 knots based on the larval distribution, which is one order of magnitude slower than that by the Kuroshio (1.5-3 knots). Habitat temperature gradually declined with growth in both the Kuroshio and KBCNT, but in the KBCNT it was 1-2 °C lower than in the Kuroshio. Our results suggest that the two different larval transport processes lead to a significant difference in the transport route, habitat conditions (such as temperature and food), and site where young fish recruit to the demersal habitat, which will result in different survival and recruitment processes.

  1. Holbrook Substation Superconductor Cable System, Long Island, New York Final Report

    The LIPA Superconductor project broke ground on July 4, 2006, was first energized on April 22, 2008 (Earth Day) and was commissioned on June 25, 2008. Since commissioning, up until early March, 2009, there were numerous refrigeration events that impacted steady state operations. This led to the review of the alarms that were being generated and a rewrite of the program logic in order to decrease the hypersensitivity surrounding these alarms. The high temperature superconductor (HTS) cable was energized on March 5, 2009 and ran uninterrupted until a human error during a refrigeration system switchover knocked the cable out of the grid in early February 2010. The HTS cable was in the grid uninterrupted from March 5, 2009 to February 4, 2010. Although there have been refrigeration events (propagated mainly by voltage sags/surges) during this period, the system was able to automatically switch over from the primary to the backup refrigeration system without issue as required during this period. On February 4, 2010, when switching from the backup over to the primary refrigeration system, two rather than one liquid nitrogen pumps were started inadvertently by a human error (communication) causing an overpressure in the cable cooling line. This in turn activated the pressure relief valve located in the grounding substation. The cable was automatically taken out of the grid without any damage to the components or system as a result of signals sent from the AMSC control cabinet to the LIPA substation. The cable was switched back into the grid again on March 16, 2010 without incident and has been operational since that time. Since switching from the backup to the primary is not an automatic process, a recent improvement was added to the refrigeration operating system to allow remote commands to return the system from backup to primary cooling. This improvement makes the switching procedure quicker since travel to the site to perform this operation is no longer necessary and safer since it is now a programmed procedure versus the former written procedure that was still subject to human variation in the process.

    In environmental monitoring, environmental impact assessments and environmental audits, topographical maps play an essential role in providing a means by which the locations of sampling sites may be selected, in assisting with the interpretation of physical features, and in indicating the impact or potential impact on an area due to changes in the system being monitored (e.g., spatially changing features such as wetlands). Global Navigation Satellite Systems (GNSS) are hereby presented as a rapid method for monitoring spatial changes to support environmental monitoring decisions and policies. To validate the GNSS-based method, a comparison is made of results from a small-scale topographic survey using radio-based real-time kinematic GNSS (GNSS-RTK) and total station survey methods at Jack Finnery Lake, Perth, Australia. The accuracies achieved by the total station in this study were 2 cm horizontally and 6 cm vertically, while the GNSS-RTK also achieved an accuracy of 2 cm horizontally, but only 28 cm vertically. While the GNSS-RTK measurements were less accurate in the height component compared to those from the total station method, it is still capable of achieving accuracies sufficient for a topographic map at a scale of 1:1,750 that could support environmental monitoring tasks such as identifying spatial changes in small water bodies or wetlands. The time taken to perform the survey using GNSS-RTK, however, was much shorter compared to the total station method, thereby making it quite suitable for monitoring spatial changes within an environmental context, e.g., dynamic mining activities that require rapid surveys and the updating of the monitored data at regular intervals.

    Full Text Available Background: Treatment with buceng combination of Eurycoma longifolia Jack and Pimpinella alpine Molk has been proven to increase testosterone level, decrease apoptosis and caspase3 expression. Bcl2 is an antiapoptotic protein found in cytoplasm which inhibits cells apoptosis. This study was aimed to investigate the effect of buceng on Bcl2 expression on penile and prostate tissues of the rats. Methods: In this experimental study, 24 male Sprague Dawley rats of 90 days old, weighing ± 300 grams, were randomly assigned into four groups. Group A, normal rats. Group B, castrated rats and treated with buceng 100 mg/day, per oral (Cast-Bcg; Group C, castrated rats and treated with 2 ml of water as placebo against buceng (Cast-Plac. Group D, castrated rats, treated with mesterolone 6.75 mg/day, per oral, as exogenous testosterone (Cast-Mest. All rats were treated for 30 days. Manova test was used to analyze the different expression of Bcl2 among groups with significance level at p ≤ 0.05. Results: Castration was associated with significant decrease of Bcl2 expression in the penile and prostate tissues (53.0 and 50.9%, respectively compared to normal rats (82.6 and 84.2%, respectively, p < 0.001. Treatment with mesterolone reversed Bcl2 expression (77.1 and 78.1% to a near normal level. The same level of Bcl2 expression was also observed with buceng treatment (73.8 and 78.2%.Conclusion: The treatment with buceng could enhance Bcl2 expression in penile and prostate tissues, comparable to normal rats and mesterolone treated rats.

  7. Antioxidant Activity and ROS-Dependent Apoptotic Effect of Scurrula ferruginea (Jack Danser Methanol Extract in Human Breast Cancer Cell MDA-MB-231.

    Full Text Available Scurrula ferruginea (Jack Danser is one of the mistletoe species belonging to Loranthaceae family, which grows on the branches of many deciduous trees in tropical countries. This study evaluated the antioxidant activities of S. ferruginea extracts. The cytotoxic activity of the selected extracts, which showed potent antioxidant activities, and high phenolic and flavonoid contents, were investigated in human breast cancer cell line (MDA-MB-231 and non-cancer human skin fibroblast cells (HSF-1184. The activities and characteristics varied depending on the different parts of S. ferruginea, solvent polarity, and concentrations of extracts. The stem methanol extract showed the highest amount of both phenolic (273.51 ± 4.84 mg gallic acid/g extract and flavonoid contents (163.41 ± 4.62 mg catechin/g extract and strong DPPH• radical scavenging (IC50 = 27.81 μg/mL and metal chelation activity (IC50 = 80.20 μg/mL. The stem aqueous extract showed the highest ABTS•+ scavenging ability. The stem methanol and aqueous extracts exhibited dose-dependent cytotoxic activity against MDA-MB-231 cells with IC50 of 19.27 and 50.35 μg/mL, respectively. Furthermore, the extracts inhibited the migration and colony formation of MDA-MB-231 cells in a concentration-dependent manner. Morphological observations revealed hallmark properties of apoptosis in treated cells. The methanol extract induced an increase in ROS generation and mitochondrial depolarization in MDA-MB-231 cells, suggesting its potent apoptotic activity. The present study demonstrated that the S. ferruginea methanol extract mediated MDA-MB-231 cell growth inhibition via induction of apoptosis which was confirmed by Western blot analysis. It may be a potential anticancer agent; however, its in vivo anticancer activity needs to be investigated.

    Eddy covariance (EC) is often used to measure the movement and direction of energy and trace gas concentrations in ecosystems. Data from EC networks are often combined with remote sensing data and ecosystem models in order to assess the spatial and temporal variability of carbon dioxide (CO{sub 2}) exchanges within specific areas of interest. This study presented a new method of determining changes in the structural characteristics of biomass and elevation. Lidar was used within the contours of half-hourly flux footprint areas to characterize vegetation structure and elevation. The influences of vegetation structure and elevation on CO{sub 2} concentrations were measured by EC and Lidar measurements for 3 mature growing periods at a mature jack pine site in Saskatchewan. Mensuration data were collected over 2 periods. Meteorological, CO{sub 2}, and H2O flux measurements were collected for 30 minute periods each day. Statistical analyses were conducted to determine the influence of meteorological variables on vegetation structure. Footprint contour lines were then layered onto the canopy height models derived by the lidar data. Multiple regression equations were used to determine net ecosystem productivity (NEP) and gross ecosystem productivity (GEP) using meteorological variables, canopy fractional cover; and elevation, as well as the results obtained from a Landsberg equation. The study showed that differences in NEP variability were influenced by differences in canopy and ground surface characteristics within the site. EC measurements underestimated gross CO{sub 2} fluxes by 5 per cent as the biomass was lower within the immediate vicinity of the EC network. It was concluded that canopy structures and elevation are important factors for determining annual carbon balances. 36 refs., 8 tabs., 9 figs.

    The nucleoprotein AHNAK is an unusual and somewhat mysterious scaffolding protein characterised by its large size of approximately 700 kDa. Several aspects of this protein remain uncertain, including its exact molecular function and regulation on both the gene and protein levels. Various studies have attempted to annotate AHNAK and, notably, protein interaction and expression analyses have contributed greatly to our current understanding of the protein. The implicated biological processes are, however, very diverse, ranging from a role in the formation of the blood-brain barrier, cell architecture and migration, to the regulation of cardiac calcium channels and muscle membrane repair. In addition, recent evidence suggests that AHNAK might be yet another accomplice in the development of tumour metastasis. This review will discuss the different functional roles of AHNAK, highlighting recent advancements that have added foundation to the proposed roles while identifying ties between them. Implications for related fields of research are noted and suggestions for future research that will assist in unravelling the function of AHNAK are offered. Copyright © 2014 Elsevier Inc.

    Spinocerebellar ataxia also referred to as hereditary ataxia comprises different forms of progressive neurodegenerative diseases. A complex mode of inheritance was most likely in Parson Russell Terriers (PRT) and in Jack Russell Terriers (JRT). Recently, the missense mutation KCNJ10:c.627C > G was shown to be associated with the spinocerebellar ataxia (SCA) in JRT and related Russell group of terriers, whereas the missense mutation CAPN1:c.344G > A was associated with late onset ataxia (LOA) in PRT. We performed a genome-wide association study (GWAS) in PRT including 15 cases and 29 controls and found a statistically strong signal in the genomic region on dog chromosome 38 (CFA38) where KCNJ10 is located. We tested the CAPN1:c.344G > A and KCNJ10:c.627C > G (Transcript XM_545752.4) mutations in a sample of 77 PRT and 9 JRT from Germany as well as further 179 controls from 20 different dog breeds. All cases and controls genotyped carried the wild-type for the CAPN1:c.344G > A mutation. Among the PRT, 17/77 (22.1 %) dogs were homozygous for the mutant KCNJ10 allele and 22/77 (28.6 %) dogs were heterozygous. Three cases of PRT had the homozygous KCNJ10 wild-type. In JRT, 1/3 cases did show the mutant KCNJ10 allele homozygous. Thus, we sequenced the KCNJ10 exons with their adjacent regions from 10 PRT and 3 JRT including the animals with imperfect co-segregation of the c.627C > G mutation. We identified a total of 45 genetic variants within KCNJ10. The most likely variant explaining the cases appeared a 1-bp-insertion in a C-stretch within exon 3 (KCNJ10:g.22141027insC). In silico analysis showed that this indel may influence the regulation of gene expression. In the present study, 16/21 cases of hereditary ataxia perfectly co-segregated with the KCNJ10:c.627C > G mutation. The CAPN1:c.344G > A mutation could not be validated and seems to be a rare variant in the samples screened. Screening KCNJ10 for further mutations did result in a

    Cardicola Short, 1953 is a genus of the Aporocotylidae Odhner, 1912 (Digenea), with 25 currently recognised species described from 32 species of Perciformes and Mugiliformes fishes around the world, including eight species from the Great Barrier Reef. Here, we describe two new species from this region, namely Cardicola beveridgei n. sp. from the ventricle and atrium of the mangrove jack, Lutjanus argentimaculatus (Forsskål) (Perciformes: Lutjanidae), and Cardicola bullardi n. sp. from the ventricle of the Australian spotted mackerel, Scomberomorus munroi Collette & Russo (Perciformes: Scombridae), from off Lizard Island, Queensland, Australia. These two new species are most easily distinguished from the 25 current members of Cardicola in having the combination of i) a spinous oral sucker, ii) an anteriorly intercaecal ovary, iii) a uterus that extends anteriorly from the oötype, iv) the number of spines per ventrolateral transverse row, and in v) body size and the length/width ratio, vi) the oesophagus and caecal length(s) relative to body total length, vii) the length of the posterior caeca relative to the anterior pair, viii) the testis length/width ratio and its total size relative to that of the body, ix) the postovarian field as a percentage of body length, and x) egg size. In addition, C. beveridgei n. sp. is further differentiated by possessing a female genital pore that opens anterodextral to the male pore while C. bullardi n. sp. differs further in possessing a testis that is almost entirely intercaecal and does not extend anteriorly to the level of the intestinal bifurcation. Employing genetic analysis of ITS2 rDNA sequence data, representing these species and a further 13 recognised and three putative species of Cardicola, we were able to unequivocally confirm these specimens as distinct (9-22% different over 420 nucleotide positions). Distance analysis of ITS2 showed that i) species of Cardicola from the Siganidae formed a monophyletic clade, to the

    Full Text Available Lead (Pb is one of the main soil contaminants. It is also of difficult phytoremediation due to its low solubility and high retention on soil particles. EDTA application to soil is a strategy to increase heavy metal phytoextraction, but such chelants usually cause phytotoxicity and metal leaching side effects. Therefore, these research work objectives were to evaluate the effects of single (0.5 g kg-1 and split (0.25 + 0.25 g kg-1 EDTA application on Pb uptake by jack beans (Canavalia ensiformis L. as well as on Pb vertical movement in a Pb contaminated soil material. Two sets of experiments were carried out under greenhouse conditions: in the first one, plants were grown in 3L-pots filled with a Pb-contaminated soil to evaluate Pb uptake by plants; for the second experiment, PVC-columns (42 cm height were used to evaluate soil Pb leaching: the upper half-column (20 cm was filled up with Pb-contaminated soil (1800 mg kg-1 whereas the lower half-column (20 cm was filled with clean soil. Ten 60 mm-rainfalls with a duration of five hours were simulated by dropping distilled water on the top of columns, and leachates were collected for chemical analysis. Plants did not show any visual Pb toxicity symptoms or reduction in dry matter yield. Nevertheless, Pb uptake by jack beans regarded as total plant Pb accumulation was higher in EDTA-treated plants. Vertical Pb movement was observed mostly for the single EDTA application. EDTA addition to the soil favor Pb-phytoextraction by jack beans and the split EDTA application decrease the metal leaching, indicating less risk of environmental contamination.O chumbo (Pb é um dos principais contaminantes de solo. Os processos de remediação são dificultados devido à alta retenção do elemento às partículas do solo. A utilização do EDTA para aumentar a fitoextração dos metais do solo tem apresentado bons resultados. Contudo, os quelantes podem causar efeitos indesejáveis como a fitotoxidez e a lixivia

    2015-02-01

    In order to limit the impact of the recent pandemics ignited by viral host jumps, it is necessary to better understand the ecological and evolutionary factors influencing the early steps of emergence and the interactions between them. Antagonistic pleiotropy, that is, the negative fitness effect in the primary host of mutations allowing the infection of and the multiplication in a new host, has long been thought to be the main limitation to the evolution of generalist viruses and thus to emergence. However, the accumulation of experimental examples contradicting the hypothesis of antagonistic pleiotropy has highlighted the importance of other factors such as the epistasis between mutations increasing the adaptation to a new host. Epistasis is pervasive in viruses, affects the shape of the adaptive landscape and consequently the accessibility of evolutionary pathways. Finally, recent studies have gone steps further in the complexity of viral fitness determinism and stressed the potential importance of the epistatic pleiotropy and of the impact of host living conditions.

  19. DARPP-32, Jack of All Trades… Master of Which?

    Science.gov (United States)

    Yger, Marion; Girault, Jean-Antoine

    2011-01-01

    DARPP-32 (PPP1R1B) was discovered as a substrate of cAMP-dependent protein kinase (PKA) enriched in dopamine-innervated brain areas. It is one of three related, PKA-regulated inhibitors of protein phosphatase-1 (PP1). These inhibitors seem to have appeared in early vertebrate ancestors, possibly Gnathostomes. DARPP-32 has additional important biochemical properties including inhibition of PKA when phosphorylated by Cdk5 and regulation by casein kinases 1 and 2. It is highly enriched in specific neuronal populations, especially striatal medium-size spiny neurons. As PP1 inhibitor DARPP-32 amplifies and/or mediates many actions of PKA at the plasma membrane and in the cytoplasm, with a broad spectrum of potential targets and functions. DARPP-32 also undergoes a continuous and tightly regulated cytonuclear shuttling. This trafficking is controlled by phosphorylation of Ser-97, which is necessary for nuclear export. When phosphorylated on Thr-34 and dephosphorylated on Ser-97, DARPP-32 can inhibit PP1 in the nucleus and modulate signaling pathways involved in the regulation of chromatin response. Recent work with multiple transgenic and knockout mutant mice has allowed the dissection of DARPP-32 function in striato-nigral and striato-pallidal neurons. It is implicated in the action of therapeutic and abused psychoactive drugs, in prefrontal cortex function, and in sexual behavior. However, the contribution of DARPP-32 in human behavior remains poorly understood. Post-mortem studies in humans suggest possible alterations of DARPP-32 levels in schizophrenia and bipolar disorder. Genetic studies have revealed a polymorphism with possible association with psychological and psychopathological traits. In addition, a short isoform of DARPP-32, t-DARPP, plays a role in cancer, indicating additional signaling properties. Thus, DARPP-32 is a non-essential but tightly regulated signaling hub molecule which may improve the general performance of the neuronal circuits in which it is expressed. PMID:21927600

    1988-07-01

    This paper describes the application of a hydraulic intraoral jig to the establishment of the vertical dimension of occlusion for full denture construction. The device enables the patient to establish an occlusal height which is most comfortable without the intervention or guidance of the dentist. Six patients for whom new dentures were to be constructed in the University of Otago School of Dentistry were invited to participate in the study. A conventional technique of denture construction was employed, but an additional stage was introduced after the jaw records had been taken and the casts mounted. Each patient was instructed in the use of the hydraulic jig and was asked to find a comfortable bite height in his own time. The results were compared with occlusal heights determined by conventional subjective methods. The former results proved to be more repeatable than those utilizing rest position and an average free-way space. The results are discussed and the implications outlined. Suggestions for further research using the hydraulic jig are made and the authors conclude that the hydraulic jig may be used to determine vertical dimension for full denture construction.

The straws represented the plots and the subplots evaluation periods (0, 8, 16, 24, 40, 56, and 72 days. The residues were dried to constant weight in a forced-air oven at 65 ºC to determine the remaining dry matter, then ground and sent to a laboratory to analyze macronutrient contents. Based on the contents and remaining dry matter amounts, the remaining nutrient amounts were determined, expressed in relation to the initial amount. Non-linear models were fit to the values, choosing the best adjustment in each case. Biomass quantity, N and Ca contents and cycling of nutrient quantities was greatest in the intercropping straw. The decomposition and nutrient release speeds were also highest in millet - jack - bean intercropping straw.

    Full Text Available Propagation of Myrmecodia tuberosa was developed for induction shoot from different explant sources by using various plant growth regulators PGRs. Cotyledons hypocotyls tubers and roots on initiation shoot tip and axillar bud on multiplication stages have been successfully regenerated on Murashige and Skoog MS medium agar. The effects of PGRs BA-6 benzylaminopurine BAP on initiation BAP GA3-Gibberelic acid GA3 on multiplication and NAA-amp945-Naphthalene acetic acid NAA on rooting were studied. Various medium both single and combination viz coco peat fern charcoal and moss on acclimatization stage were describe. The results showed that different explant sources of M. tuberosa were potentially produced high number of shootswhich was influenced by the varying concentration of PGRs. In initiation stage the optimum number of shoots 15.60 per explantwas obtained from hypocotyls on MS medium agar with BAP 4 mgL for 12 weeks while axillar bud on MS medium agar BAP 9 mgL resulted the highest number of shoots 36.60 per explant for 12 weeks in multiplication stage. In rooting stage the addition of NAA 0.15 mgL on MS medium agar was found as optimum PGRs to obtain highest number of root 18.40 root per explant. Plantlets of M. Tuberosa were also successfully acclimatized at green house in coco peatmoss and fernmoss medium in acclimatization with 100 survival. Therefore it is suggested that the use of specific source e1xplant PGRs either initial multiplication or rooting and certain combination of medium in acclimation stage are important to be applied in order to increase the population of Myrmecodia tuberosa from North Borneo Island.

    Full Text Available Abstract Background Toxoplasma gondii infection causes toxoplasmosis, an infectious disease with worldwide prevalence. The limited efficiency of drugs against this infection, their side effects and the potential appearance of resistant strains make the search of novel drugs an essential need. We examined Eurycoma longifolia root extract and fractions as potential sources of new compounds with high activity and low toxicity. The main goal of this study was to investigate the anti-T. gondii activity of crude extract (TACME and four fractions (TAF 273, TAF 355, TAF 191 and TAF 401 from E. longifolia, with clindamycin as the positive control. Methods In vitro toxoplasmacidal evaluation was performed using Vero cells as host for T. gondii. Light microscopy technique was used to study in situ antiparasitic activity. Results Significant anti-T. gondii activity was observed with clindamycin (EC50 = 0.016 μg/ml, follow by TAF 355 (EC50 = 0.369 μg/ml and TAF 401 (EC50 = 0.882 μg/ml. Light microscopy revealed that most Vero cells were infected after 3 h of exposure to T. gondii. After 36 h of exposure to the E. longifolia fraction, the host Vero cells showed no visible intracellular parasite and no remarkable morphological changes. Conclusions Our study demonstrated that TAF 355 and TAF401 fractions may be the sources of new anti-T. gondii compounds.

    2007-09-01

    Full Text Available This book serves as a comprehensive guide to action research. It provides useful information on how to undertake an action research project, write reports and disseminate research findings. Specifically, it explains how to identify a research question, map out an action plan, use appropriate methodologies and generate evidence from the data to test findings against the most stringent critiques. In doing so, the book provides justification for action research and its potential scholarly benefits. The book achieves most of the objectives set out by the authors in the introductory section. The strength of the book is reflected in the authors' skillful organization of key concepts in a manner that follows a logical order. Chapters, sections, and subsections respond to questions posed at the beginning of each section. The use of examples and case studies is especially helpful in educating researchers about all aspects associated with "doing action research." The book is written more for a practitioner-scholar than for scholar-practitioner. However, the book only marginally succeeds in contextualizing action research in the larger theoretical and interdisciplinary discourse. URN: urn:nbn:de:0114-fqs070382

  2. GUN1, a jack-of-all-trades in chloroplast protein homeostasis and signaling

    Directory of Open Access Journals (Sweden)

    Monica Colombo

    2016-09-01

    Full Text Available The GUN1 (GENOMES UNCOUPLED 1 gene has been reported to encode a chloroplast-localized pentatricopeptide-repeat protein, which acts to integrate multiple indicators of plastid developmental stage and altered plastid function, as part of chloroplast-to-nucleus retrograde communication. However, the molecular mechanisms underlying signal integration by GUN1 have remained elusive, up until the recent identification of a set of GUN1-interacting proteins, by co-immunoprecipitation and mass-spectrometric analyses, as well as protein-protein interaction assays. Here, we review the molecular functions of the different GUN1 partners and propose a major role for GUN1 as coordinator of chloroplast translation, protein import and protein degradation. This regulatory role is implemented through proteins that, in most cases, are part of multimeric protein complexes and whose precise functions vary depending on their association states. Within this framework, GUN1 may act as a platform to promote specific functions by bringing the interacting enzymes into close proximity with their substrates, or may inhibit processes by sequestering particular pools of specific interactors. Furthermore, the interactions of GUN1 with enzymes of the tetrapyrrole biosynthesis pathway support the involvement of tetrapyrroles as signaling molecules in retrograde communication.

    No detailed studies have been performed to date on osmotolerance in cryptophytes, although one species, Chroomonas africana, had previously been reported to grow in freshwater as well as seawater. This study focused on osmotolerance in Chroomonas. Growth at different osmolalities and parameters of contractile vacuole function were examined and compared across a high-resolution phylogeny. Two evolutionary lineages in the Chroomonas clade proved to be euryhaline. Ranges of osmotolerance depended not only on osmolality, but also on culture medium. All cryptophytes contained contractile vacuoles. In the euryhaline strain CCAP 978/08 contractile vacuoles could be observed even at an osmolality beyond that of seawater. In addition the cells accumulated floridoside, an osmoprotectant likely originating from the red algal carbohydrate metabolism of the complex rhodoplast. Further evidence for functional contractile vacuoles also in marine cryptophytes was provided by identification of contractile vacuole-specific genes in the genome of Guillardia theta.

    The etiology of Crohn's disease and ulcerative colitis, the two major forms of inflammatory bowel disease (IBD), is still largely unknown. However, it is now clear that the abnormalities underlying pathogenesis of intestinal inflammation are not restricted to those mediated by classic immune cells but also involve nonimmune cells. In particular, advances in vascular biology have outlined a central and multifaceted pathogenic role for the microcirculation in the initiation and perpetuation of IBD. The microcirculation and its endothelial lining play a crucial role in mucosal immune homeostasis through tight regulation of the nature and magnitude of leukocyte migration from the intravascular to the interstitial space. Chronically inflamed IBD microvessels display significant alterations in microvascular physiology and function compared with vessels from healthy and uninvolved IBD intestine. The investigation into human IBD has demonstrated how endothelial activation present in chronically inflamed IBD microvessels results in a functional phenotype that also includes leakiness, chemokine and cytokine expression, procoagulant activity, and angiogenesis. This review contemplates the newly uncovered contribution of intestinal microcirculation to pathogenesis and maintenance of chronic intestinal inflammation. In particular, we assess the multiple roles of the microvascular endothelium in innate immunity, leukocyte recruitment, coagulation and perfusion, and immune-driven angiogenesis in IBD.

  13. Permeability Enhancement in Enhanced Geothermal System as a result of Hydraulic Fracturing and Jacking

    2016-04-01

    A decameter-scale in-situ hydraulic stimulation and circulation (ISC) experiment has been initiated by the newly-founded Swiss Competence Centre for Energy Research - Supply of Electricity (SCCER-SoE) at Nagra's Grimsel Test Site (GTS) as a part of the work-package WP1 of the Deep Underground Laboratory (DUG-Lab) initiative. The experiment area is situated in the southern part of the GTS in a low fracture density volume of the Grimsel granodiorite. The hydraulic properties of the granitic rock mass are supposed to be similar to those expected in the crystalline basement of the alpine foreland where deep enhanced geothermal systems might be developed in future. The main objectives of the multi-disciplinary experiment are to provide a high resolution pre- and post-stimulation characterization of fracture permeability and connectivity, to investigate patterns of preferential flow paths, to describe the pressure propagation during the stimulation phases and to evaluate the efficiency of the fracture-matrix heat exchanger. A comprehensive test & monitoring layout including a fair number of boreholes instrumented with a variety of sensors (e.g. pressure, strain, displacement, temperature, and seismic sensors) is designed to collect detailed data during multiple hydraulic stimulation runs. The diffusion of fluid pressure is expected to be governed mainly by the properties and geometry of the existent fracture network. The hydraulic transmissivity of fractures are in the range of 10-7 to 10-9 m2/s whereas the matrix rock has a very low hydraulic conductivity (K ˜ 10-12 m/s). As part of the stress measurement campaign during the pre-stimulation phase of the ISC experiment, a series of hydraulic fracturing (HF) and hydraulic tests in pre-existing fractures (HTPF) were conducted. The tests were accompanied by micro-seismic monitoring within several observation boreholes to investigate the initiation and propagation of the induced fractures. Together with results from over-coring tests, these data were used to conclude on the local stress orientation and stress magnitudes. The hydraulic response of the rock mass under hydro-mechanical perturbations was investigated by conducting various hydraulic packer tests (e.g. pulse, constant rate and constant head) in multiple hydraulically isolated borehole sections before and after the stress measurements. Hydraulic testing of borehole sections which were previously fracked (during HF tests) didn't show a distinct increase in permeability. For the tested borehole sections without natural fractures, this can be explained by the fact that hydraulic fracturing was dominated by fracture normal opening (mode I). In this case, the implemented pressure range (less than 2 MPa) during the hydraulic packer tests was not sufficient to re-open the tensile fractures and permeability would remain unchanged. Conversely, in borehole sections with pre-existing ductile and/or brittle fractures and where HTPF-tests were conducted, the permeability increased by two orders of magnitude, from 10-11 m2/s to˜10-9 m2/s (results of hydraulic tests pre and post HTPF). These findings could be explained by permanent enhancement of permeability as a result of shear dilation of existing structures. Considering the efficiency of the hydraulic stimulation process observed at low differential injection pressures, even more significant permeability enhancement is expected during the upcoming stimulation experiments.

  16. Jack-of-all-trades master of all? Snake vertebrae have a generalist inner organization

    Science.gov (United States)

    Houssaye, Alexandra; Boistel, Renaud; Böhme, Wolfgang; Herrel, Anthony

    2013-11-01

    Snakes are a very speciose group of squamates that adapted to various habitats and ecological niches. Their ecological diversity is of particular interest and functional demands associated with their various styles of locomotion are expected to result in anatomical specializations. In order to explore the potential adaptation of snakes to their environment we here analyze variation in vertebral structure at the microanatomical level in species with different locomotor adaptations. Vertebrae, being a major element of the snake body, are expected to display adaptations to the physical constraints associated with the different locomotor modes and environments. Our results revealed a rather homogenous vertebral microanatomy in contrast to what has been observed for other squamates and amniotes more generally. We here suggest that the near-absence of microanatomical specializations in snake vertebrae might be correlated to their rather homogeneous overall morphology and reduced range of morphological diversity, as compared to lizards. Thus, snakes appear to retain a generalist inner morphology that allows them to move efficiently in different environments. Only a few ecologically highly specialized taxa appear to display some microanatomical specializations that remain to be studied in greater detail.

    Delineation of the typical disease progression in canine paroxysmal dyskinesia (PD) may assist in evaluating therapeutic agents during clinical trials. Our objective was to establish the natural disease course in a group of dogs diagnosed with PD that received no medication. Fifty-nine dogs (36 Labradors, 23 JRTs) with clinically confirmed PD and a follow-up of ≥3 years were retrospectively reviewed. Dogs with PD had a young onset, were triggered by startle or sudden movements, and had a male bias (75%) with the majority being entire sample population. Twenty-one dogs (36%) had at least one event comprising cluster episodes. Episode duration and frequency varied dramatically, even within an individual. Median follow-up was 7 years. No concurrent disease was identified in any dog that was investigated. The natural history was self-limiting with 32% entering remission and an improvement in 75%. Episodes reduced in terms of frequency and duration in Labradors and JRTs respectively. Remission was lower in dogs with cluster episodes than those without. These findings suggest that the diagnostic yield of advanced neuroimaging techniques in dogs with video footage and historical data supporting PD, without neurological deficits, is low. The presence of cluster episodes is of predictive value for the prognosis of canine PD. Future research should be cautious in reporting treatment response for PD without first considering the spontaneous remission rate and improvements in untreated dogs documented in this study.

    Jensen, Jørgen Juncher

    2010-01-01

    It is well known from linear analyses in stochastic seaway that the mean out-crossing rate of a level r is given through the reliability index, defined as r divided by the standard deviation. Hence, the reliability index becomes inversely proportional to the significant wave height. For non......-linear processes the mean out-crossing rate depends non-linearly on the response level r and a good estimate can be found using the First Order Reliability Method (FORM), see e.g. Jensen and Capul (2006). The FORM analysis also shows that the reliability index is strictly inversely proportional to the significant...... wave height irrespectively of the non-linearity in the system. However, the FORM analysis only gives an approximation to the mean out-crossing rate. A more exact result can be obtained by Monte Carlo simulations, but the necessary length of the time domain simulations for very low out-crossing rates...

    Successional changes in belowground ectomycorrhizal fungal (EMF) communities have been observed with increasing forest stand age; however, mechanisms behind this change remain unclear. It has been hypothesized that declines of inorganic nitrogen (N) and increases of organic N influence changes in EMF taxa over forest development. In a post-wildfire chronosequence of...

  3. BOOK REVIEW: JACK D. ELLER, FROM CULTURE, TO ETHNICITY, TO CONFLICT: AN ANTHROPOLOGICAL PERSPECTIVE ON INTERNATIONAL ETHNIC CONFLICTS

    2011-03-01

    Full Text Available From Culture, to Ethnicity, to Conflict: An Anthropological Perspective on International Ethnic Conflicts, Eller illustrates that the characteristics used to define ethnicity cannot be freely applied to all groups since group perception of what their ethnicity encompasses vary significantly. Further, Eller points out that once a group becomes self-conscious of their difference within society, this realization leads to the initiation of group mobilization, from this viewpoint a group is then considered a nationalistic group as opposed to a mere ethnic group within society. This was evident in Sir Lanka when both the Sinhalese and the Tamils were aware of their differences and had established their own nationalistic group, wherein each nationalistic group seeks to control the island. Taken as a whole, Eller’s From Culture, to Ethnicity, to Conflict: An Anthropological Perspective on International Ethnic Conflicts, offers an insightful and extensive understanding of ethnicity and conflict, by arguing that ethnicity and conflict have developed out of modern social condition and circumstances, as opposed to primordial dynamics. The move away from primordial understanding sheds light into why once dormant groups become politically active as in the cases presented by Eller.

    More than thirty years ago the era of compound systems of thermal insulation started - using five to eight centimetres thin polystyrene insulation panels, in the 1970ies the pioneers of the facade insulation responded to the dictation of the oil sheik and set thereby the course for the development of an energy efficient design for the first time. In the meantime the thermoskins of the first hour lost some of its shine and also correspond no more to the today's insulation standard. Their retrofitting lines up. Thus the question arises: Demolition, disposal and assembly of a new compound system of thermal insulation? Or are panels the better solution?.

    Fatigue and sleep deprivation and their effects on surgical proficiency have been actively researched areas. Past studies that have focused solely on residents have provided an important insight into how fatigue affects residents' ability to perform. This study aims to quantify the effect of fatigue on attending surgeons. To quantify the effect of fatigue on psychomotor and cognitive skills of surgical residents and attending surgeons, visiohaptic simulations were created to mimic realistic interactions. Both groups showed a significant decrement in proficiency measures postcall. When tasks were separated based on psychomotor versus cognitive-dominated skills, attending surgeons made 25% fewer (P Psychomotor skills were equally affected in both groups. Call-associated fatigue is associated with increased error rates in the cognitive skill domain, although less so in attending surgeons compared with their resident counterparts.

    2016-06-01

    Full Text Available This study investigated the influence of utilizing a collegiate mascot as a marketing tool for the promotion of fruit and vegetable intake and physical activity among 4th grade students. The program utilized service learning and formative research for the development of a social marketing campaign comprised of nutrition education and brand marketing. A pre-test/post-test design was used to measure fruit and vegetable intake and physical activity in participants in intervention and control schools. Awareness and understanding of the campaign was assessed post-intervention. There were no changes in fruit and vegetable intake or physical activity. However, 91% of the intervention students were able to correctly report understanding of the campaign messages, and approximately one-third of the participants were able to recall the campaign without any prompts. Results demonstrated how a social marketing campaign can utilize branding techniques to bring about awareness, which is an essential step in initiating behavior change.

    Full Text Available Bidens pilosa está presente em praticamente todo o território brasileiro, além de vários outros habitats tropicais. Entre as características presentes na planta, a abundante e longa produção de propágulos, o fotoblastismo preferencial, o uso eficiente da água, a elevada extração e utilização de nutrientes, bem como características morfofisiológicas específicas, conferem vantagem na competição com as principais culturas anuais e perenes. Devido à plasticidade e flexibilidade adaptativa de B. pilosa e às interações de suas características na determinação da competitividade desse vegetal, torna-se difícil identificar aquelas que realmente se associam com elevada capacidade competitiva e que possuam maior expressividade. Dentro da espécie ocorrem biótipos resistentes a determinados herbicidas, o que dificulta seu controle nas áreas agrícolas. O uso de outros métodos de manejo também possui entraves, devido à ampla variação do fluxo de disseminação, germinação e emergência de propágulos e, ainda, às associações benéficas dessa espécie com microrganismos presentes no solo. Embora seja dotada de características que a tornam infestante agressiva nas áreas agrícolas, este trabalho reporta alguns mecanismos que podem ser usados para o manejo integrado da espécie. Além disso, B. pilosa apresenta propriedades medicinais, sendo necessário o aprofundamento científico para usufruto de seus benefícios.Bidens pilosa occurs in practically all the Brazilian territory, besides several other tropical habitats. This plant's most advantageous aspects in the competition with major annual and perennial cultivars are its abundant and long propagule production, preferential photo-blastism, water use efficiency, high nutrient extraction and use, and morphophysiological characteristics. Due to B. pilosas plasticity and adaptative flexibility, as well as interaction of the characteristics determining its competitiveness, it is difficult to identify those which are associated with higher competitive capacity and expressiveness. This species presents biotypes resistant to some herbicides, rendering its control difficult in agricultural areas. The use of other management methods is also difficult, due to the wide variation in the flow of propagule dissemination, germination and emergence, as well as the beneficial association of this weed with microorganisms present in the soil. Although this plant has aggressive infesting characteristics, this work has reported some mechanisms that can be used for its integrated management. B. pilosa also presents medical properties, with extensive scientific studies being necessary in order to obtain benefits.

    2012-01-01

    Species utilizing a wide range of resources are intuitively expected to be less efficient in exploiting each resource type compared to species which have developed an optimal phenotype for utilizing only one or a few resources. We report here the results of an empirical study whose aim was to test for a negative association between habitat niche breadth and foraging performance. As a model system to address this question, we used two highly abundant species of pit-building antlions varying in their habitat niche breadth: the habitat generalist Myrmeleon hyalinus, which inhabits a variety of soil types but occurs mainly in sandy soils, and the habitat specialist Cueta lineosa, which is restricted to light soils such as loess. Both species were able to discriminate between the two soils, with each showing a distinct and higher preference to the soil type providing higher prey capture success and characterizing its primary habitat-of-origin. As expected, only small differences in the foraging performances of the habitat generalist were evident between the two soils, while the performance of the habitat specialist was markedly reduced in the alternative sandy soil. Remarkably, in both soil types, the habitat generalist constructed pits and responded to prey faster than the habitat specialist, at least under the temperature range of this study. Furthermore, prey capture success of the habitat generalist was higher than that of the habitat specialist irrespective of the soil type or prey ant species encountered, implying a positive association between habitat niche-breadth and foraging performance. Alternatively, C. lineosa specialization to light soils does not necessarily confer upon its superiority in utilizing such habitats. We thus suggest that habitat specialization in C. lineosa is either an evolutionary dead-end, or, more likely, that this species' superiority in light soils can only be evident when considering additional niche axes.

    2016-09-23

    The geology of the Ozark National Scenic Riverways (ONSR) in southern Missouri has been mapped at 1:24,000 scale. This endeavor was achieved through the combined efforts of U.S. Geological Survey and Missouri Geological Survey individual quadrangle mapping and additional fieldwork by the authors of this report. Geologic data covering the area of the ONSR and a 1-mile (1.6-kilometer) buffer zone surrounding the park, as well as geologic data from a few key adjoining areas, have been compiled into a single, seamless geographic information system database. The intent is to provide base geologic information for natural science research and land management in the park and surrounding areas. The data are served online at ScienceBase (https://www.sciencebase.gov/catalog/), where they are provided in Environmental Systems Research Institute (ESRI) file geodatabase format, and are accompanied by metadata files. These data can be accessed at: http://dx.doi.org/10.5066/F7CJ8BKB. Additional detailed geologic information about the ONSR and surrounding areas is available in the separate 1:24,000-scale quadrangle maps and in a 1:100,000-scale map and report on the regional geology.

    Etlingera elatior is a well-known herb in Malaysia with various pharmaceutical properties. E. elatior flowers grown in three different locations of Malaysia (Kelantan, Pahang and Johor), were investigated for differences in their content of secondary metabolites (total phenolics [TPC], total flavonoids [TFC], and total tannin content [TTC]) as well as for their antioxidant, anticancer, and antibacterial properties. Phenolic acids and flavonoids were isolated and identified using ultra-high performance liquid chromatography (UHPLC). Ferric reducing antioxidant potential (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays were used to evaluate the antioxidant activities. The anticancer activity of extracts was evaluated using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. When extracted with various solvents (aqueous and ethanolic), samples from the different locations yielded significantly different results for TPC, TFC, and TTC as well as antioxidant activity. Aqueous extracts of E. elatior flowers collected from Kelantan exhibited the highest values: TPC (618.9 mg/100 g DM), TFC (354.2 mg/100 g DM), TTC (129.5 mg/100 g DM), DPPH (76.4 %), and FRAP (6.88 mM of Fe (II)/g) activity with a half-maximal inhibitory concentration (IC50) of 34.5 μg/mL compared with extracts of flowers collected from the other two locations. The most important phenolic compounds isolated in this study, based on concentration, were: gallic acid > caffeic acid > tannic acid > chlorogenic acid; and the most important flavonoids were: quercetin > apigenin > kaempferol > luteolin > myricetin. Extracts of flowers from Kelantan exhibited potent anticancer activity with a IC50of 173.1 and 196.2 μg/mL against the tumor cell lines MCF-7 and MDA-MB-231 respectively, compared with extracts from Pahang (IC50 = 204.5 and 246.2 μg/mL) and Johor samples (IC50 = 277.1 and 296.7 μg/mL). Extracts of E. elatior flowers also showed antibacterial activities against Staphylococcus aureus, Bacillus subtilis, Listeria monocytogenes, Escherichia coli, Salmonella typhimurium, and Pseudomonas aeruginosa with minimal inhibitory concentrations (MIC) ranging from 30 to >100 μg/mL. In general, therefore, based on the potent antioxidant and anticancer activity of flower extracts, it appears that E. elatior grown in the North-east of Malaysia (Kelantan) is a potential source of therapeutic compounds with anti-cancer activity.

    In an in experimental investigation of local recovery factors for a blade having a pressure distribution similar to that of a typical reaction-type turbine blade, it a was found that the recovery factors were essentially independent of Mach number, Reynolds number, pressure gradient, and position on the blade surface except for regions where the boundary layer was probably in the transition range from laminar to turbulent. The recommended value of local subsonic recovery factor for use in calculating the effective gas temperature for gas turbine blades was 0.89.

    Purpose: Although PET-based radiomic features have been proposed to quantify tumor heterogeneity and shown promise in outcome prediction, little is known about their relationship with tumor genetics. This study assessed the association of [{sup 18}F]fluorodeoxyglucose (FDG)-PET-based radiomic features with non-small cell lung cancer (NSCLC) mutations. Methods: 348 NSCLC patients underwent FDG-PET/CT scans before treatment and were tested for genetic mutations. 13% (44/348) and 28% (96/348) patients were found to harbor EGFR (EGFR+) and KRAS (KRAS+) mutations, respectively. We evaluated nineteen PET-based radiomic features quantifying phenotypic traits, and compared them with conventional PET features (metabolic tumor volume (MTV) and maximum-SUV). The association between the feature values and mutation status was evaluated using the Wilcoxcon-rank-sum-test. The ability of each measure to predict mutations was assessed by the area under the receiver operating curve (AUC). Noether’s test was used to determine if the AUCs were significantly from random (AUC=0.50). All p-values were corrected for multiple testing by controlling the false discovery rate (FDR{sub Wilcoxon} and FDR{sub Noether}) of 10%. Results: Eight radiomic features, MTV, and maximum-SUV, were significantly associated with the EGFR mutation (FDR{sub Wilcoxon}=0.01–0.10). However, KRAS+ demonstrated no significantly distinctive imaging features compared to KRAS− (FDR{sub Wilcoxon}≥0.92). EGFR+ and EGFR− were significantly discriminated by conventional PET features (AUC=0.61, FDR{sub Noether}=0.04 for MTV and AUC=0.64, FDR{sub Noether}=0.01 for maximum-SUV). Eight radiomic features were significantly predictive for EGFR+ compared to EGFR− (AUC=0.59–0.67, FDR{sub Noether}=0.0032–0.09). Normalized-inverse-difference-moment outperformed all features in predicting EGFR mutation (AUC=0.67, FDR{sub Noether}=0.0032). Moreover, only the radiomic feature normalized-inverse-difference-moment could significantly predict KRAS+ from EGFR+ (AUC=0.65, FDR{sub Noether}=0.05). All measures failed to predict KRAS+ from KRAS− (AUC=0.50–0.54, FDR{sub Noether}≥0.92). Conclusion: PET imaging features were strongly associated with EGFR mutations in NSCLC. Radiomic features have great potential in predicting EGFR mutations. Our study may help develop a non-invasive imaging biomarker for EGFR mutation. R.M. has consulting interests with Amgen.

    Full Text Available The use of topical retinoids to treat skin disorders and ageing can induce local reactions, while oral retinoids are potent teratogens and produce several unwanted effects. This way, efforts to explore complementary care resources should be supported. Based on this, we evaluate the antiageing effects of a supercritical CO2 extract from Bidens pilosa L. (BPE-CO2A containing a standardized multicomponent mixture of phytol, linolenic, palmitic, linoleic, and oleic acids. BPE-CO2A was assessed for its effects on human dermal fibroblasts (TGF-β1 and FGF levels using ELISA; collagen, elastin, and glycosaminoglycan by colorimetric assays, and mRNA expression of RXR, RAR, and EGFr by qRT-PCR and human skin fragments (RAR, RXR, collagen, elastin, and glycosaminoglycan by immunohistochemical analysis. Levels of extracellular matrix elements, TGF-β1 and FGF, and EGFr gene expression were significantly increased by BPE-CO2A. The modulation of RXR and RAR was positively demonstrated after the treatment with BPE-CO2A or phytol, a component of BPE-CO2A. The effects produced by BPE-CO2A were similar to or better than those produced by retinol and retinoic acid. The ability to stimulate extracellular matrix elements, increase growth factors, and modulate retinoid and rexinoid receptors provides a basis for the development of preparation containing BPE-CO2A as an antiageing/skin-repair agent.

  6. Functional categories in the noun phrase: on jacks-of-all-trades and one-trick-ponies in Danish, Dutch and German

    Rijkhoff, Jan

    2010-01-01

    This paper deals with functionally defined modifier categories of the noun phrase in some Germanic languages, in particular Danish, Dutch and German. It is argued that functional categories, unlike semantic or form-based categories, are the only categories that can be applied within and across...... languages. Formal categories are too narrow (they do not cover all the structural variants attested across languages) and semantic categories are too wide (they tend to include too many structural variants). The paper is particularly concerned with the relation between form and function of adnominal...... modifiers. Whereas members of certain formal categories (e.g. adnominal prepositional phrase or PP) can be used in several functions (e.g. as classifying, qualifying or localizing/anchoring modifiers of the noun), other adnominal modifiers always have the same function. The current investigation first...

    Pregnancy rates in donkeys after artificial insemination with cryopreserved semen are still low, compared to the horse species. Addition of autologous seminal plasma to frozen-thawed semen appeared to improve pregnancy rates. The aims of this study were to evaluate (1) sperm motility and plasma membrane integrity after thawing (T0) and after one and 2 h (T1 and T2) of post-thaw incubation in either 0% (SP0) or 70% (SP70) autologous seminal plasma and (2) sperm motility, plasma membrane integrity and DNA quality (%COMP-αt) after thawing (T0) and after 2 and 4 h (T2 and T4) of post-thaw incubation in either 0% (SP0), 5% (SP5) or 20% (SP20) homologous seminal plasma. In experiment 1, seminal plasma decreased total and progressive sperm motility and plasma membrane intact spermatozoa immediately after dilution and at all following time points (p < 0.05). In experiment 2, total and progressive motility did not differ between treatments immediately after dilution and between SP0 and SP5 at T2, while they were lower in both SP5 and SP20 than in SP0 at T4. Plasma membrane intact sperm cells did not differ between SP0 and SP5 and were lower in SP20 at all time points. DNA quality was not affected by treatment immediately after dilution and was significantly worse for SP20 after 4 h of incubation (p < 0.05). The post-thaw addition of seminal plasma at the tested concentrations did not improve donkey frozen semen characteristics in vitro over time. © 2014 Blackwell Verlag GmbH.

    In this paper, in order to clarify the seepage behavior and the influences on excavated soil of the mud slurry in using the mud pressured pushing method, based on results of model tests the applicability of Eulerian Lagrangian Analysis is confirmed. And, using this analysis method the seepage behaviors of mud slurry on soil are simulated. The results obtained are as follows. By using the Eulerian Lagrangain Analysis the seepage phenomena of the mud slurry on the soil in using the mud pressured pushing method can be clarified. The seepage behaviors on soils in which the mud slurry are injected are different depending on the mud slurry pressure and specific gravity of the mud slurry, so it is necessary to select suitable mud slurry pressure and specific gravity of the mud slurry corresponding to the site conditions. When the soil has a small slurry permeation, the injected mud slurry makes strong influences on it, but when the soil has a big slurry permeation, the injected mud slurry does not make influence on it and it is possible to form a thick mud screen around the pipe. 13 refs., 20 figs., 6 tabs.

    Full Text Available Neste trabalho, objetivou-se avaliar os efeitos de omissões de nutrientes na produção de matéria seca e nos parâmetros de crescimento do bastão-do-imperador. O trabalho foi realizado em casa de vegetação da área experimental do Departamento de Ciência do Solo da Universidade Federal de Lavras (Lavras, MG, no período de janeiro de 2007 a janeiro de 2008. O delineamento experimental foi inteiramente casualizados com quatro repetições e oito tratamentos: Solução Hoagland & Arnon completa, soluções nutritivas com as omissões de N, de P, de K, de Ca, de Mg, de S e de B. Foram avaliadas a altura das plantas, diâmetro das hastes, número de hastes, número de folhas por hastes e volume da raiz. Posteriormente, as plantas foram divididas em folhas, hastes, rizoma e raiz para determinação da massa de matéria seca de cada parte. A omissão de nutrientes afetou os parâmetros de crescimento das plantas e a produção de matéria seca. Observou-se que o bastão-do-imperador mostrou-se mais exigente em B, K, N, P e S na fase inicial de crescimento do que em Ca e Mg. A redução da matéria seca total das plantas foi influenciada na seguinte ordem: B > K > N > P > S > Mg > Ca.The objective of this work was to evaluate the effect of simple and multiple nutrient omissions on the dry matter production and growth parameters of torch ginger plants. The experiment was carried out under greenhouse conditions at the Soil Science Department of Federal University of Lavras (Lavras-MG. The experiment was started in January 2007 and lasted for 12 months, following a completely randomized design, with four replicates and eight treatments: Complete Hoagland & Arnon nutrient solution, and nutrient solutions without N, P, K, Ca, Mg, S, and B. Plant height, stem diameter, number of stems, number of leaves per stem, and volume of root were evaluated. Subsequently the plants were divided into leaf + pseudostem, rhizome, root and tillers for dry matter determination. The nutrient omissions affected the growth parameters and dry matter production. It was observed that torch ginger is more demanding in B, K, N, P and S at the initial phase of growth rather than in Ca and Mg. The reduction of the total dry matter weight of the plants was affected in the following order: B> K> N> P> S> Mg> Ca.

    Full Text Available O uso de produtos naturais para o tratamento de doenças é algo que o ser humano já está habituado a realizar desde o início dos tempos. A utilização de Etlingera elatior (Bastão do Imperador, uma herbácea muito comum nos jardins e em áreas de banhado, para o tratamento de dores musculares e reumatismo é citada pela cultura popular, o que incentivou a indústria farmacêutica a começar a investir nos estudos sobre sua atividade. Porém, a produção de biomassa através de plantas sadias e de alta qualidade ainda é incipiente. O uso da biotecnologia vegetal, especialmente a propagação vegetativa in vitro, permite a produção em larga escala de mudas e/ou biomassa vegetal, de alta qualidade genética e fitossanitária, em curto espaço de tempo e pequena área física. O objetivo deste trabalho foi avaliar o efeito de agentes desinfestantes na obtenção de explantes assépticos, da composição do meio de cultura e do seccionamento do rizoma no desenvolvimento, multiplicação e enraizamento das plantas in vitro, visando estabelecer o processo de micropropagação. Gemas laterais foram submetidas à desinfestação com etanol e hipoclorito de cálcio e de sódio. Os rizomas assépticos foram seccionados longitudinalmente e multiplicados em meio de cultura MS adicionado de BAP (0,0; 1,0 e 2,0 mg L-1. O estabelecimento das culturas assépticas a partir do uso de etanol 70%, NaClO 1% e CaClO 2 e 5% proporcionaram de 10 a 40% de sobrevivência dos explantes. A taxa de multiplicação obtida nos rizomas, inteiros e seccionados longitudinalmente e cultivados em meio MS, não apresentou diferença significativa para o número de brotos. Já o cultivo do rizoma seccionado em meio MS adicionado de 1,0 mg L-1 de BAP resultou em aumento significativo no número de brotos em relação a rizoma inteiro na mesma concentração de BAP. As plantas cultivadas na presença de BAP apresentaram redução do número de raízes a partir de rizomas inteiros. Apesar do efeito do seccionamento do rizoma e da concentração de BAP, no número de brotos e raízes, as plantas não mostraram diferença no crescimento da planta e das raízes. A micropropagação da espécie Etlingera elatior é possível, possibilitando a produção de mudas em larga escala.The use of natural products to treat diseases has been common for humans since the beginning of times. Etlingera elatior (torch ginger, an herbaceous species very common in gardens and muddy areas, has been cited by the popular culture as treatment for muscular pains and rheumatism, which has stimulated the pharmaceutical industry to start investing in studies on its activity. However, phytomass production by high-quality healthy plants is still incipient. The utilization of plant biotechnology, specially in vitro vegetative propagation, allows the large-scale production of seedlings and/or phytomass of high genetic and phytosanitary quality in a short time and small area. The aim of this work was to evaluate the action of disinfectant agents on the production of aseptic explants, as well as the effect of culture medium composition and rhizome splitting on the development, multiplication and rooting of plants in vitro in order to establish the micropropagation process. Lateral buds were disinfected with ethanol and calcium and sodium hypochlorite. Aseptic rhizomes were longitudinally sectioned and multiplied in MS culture medium containing BAP (0.0, 1.0 and 2.0 mg L-1. The establishment of aseptic cultures by using 70% ethanol, 1% NaClO and 1% and 5% CaClO resulted in 10 to 40% explant survival. The multiplication rate obtained for whole and longitudinally sectioned rhizomes cultivated in MS medium did not present significant difference for sprout number. However, sectioned rhizome cultivated in MS medium added of 1.0 mg L-1 BAP had a significant increase in sprout number, relative to whole rhizomes at the same BAP concentration. In the presence of BAP, there was a reduction in root number for whole rhizomes. Although rhizome splitting and BAP concentration affected sprout and root number, there was no difference in the growth of plants and roots. Thus, Etlingera elatior micropropagation is possible, allowing the large-scale production of seedlings.

Eighty-four of 126 subjects had relatively lower scores according to Scoring of Immunological Vigor (SIV) screening. Subjects were instructed to ingest either 200 mg/day of TA or rice powder as a placebo for 4 weeks [TA and Placebo (P) groups] and to visit a clinic in Tokyo twice (weeks 0 and 4). SIV, immunological grade, immunological age, and other immune parameters were measured. Eighty-three subjects completed the study; 40 in the TA group and 41 in the P group were statistically analyzed, whereas two were excluded from the analyses. At week 4, the SIV and immunological grade were significantly higher in the TA group than those in P group (p < 0.05). The numbers of total, naïve, and CD4(+) T cells were also higher in the TA group than those in P group (p < 0.05). No severe adverse events were observed. The results suggest that ingestion of the root water extract of TA (Physta®) enhances comprehensive immunity in both middle-aged men and women. This study is registered in UMIN-CTR (UMIN000011753).

    I studied the trap morphology, necromass accumulation rates and pitcher infauna of an eastern tropical pitcher plant, Nepenthes ampullaria, that grew in `kerangas' heath forest in the Sungei Ingei Conservation Area, Brunei. I surveyed 164 pitchers distributed among 35 plants and extracted the necromass and larval infauna from the pitchers and then resampled the pitcher contents after 14 days. Plants varied significantly in the morphology of their pitchers, in their rate of necromass accumulation per pitcher and in the abundance and composition of the pitcher infaunas. On average, pitchers accumulated 11.5 mg dry weight over 14 days, but larger pitchers accumulated more necromass than smaller ones. Pitcher morphology explained 45% of the variation in necromass accumulation among plants. On average, pitchers initially contained 26.3 individual larval inquilines. Collectively, the larval infauna was composed of nine taxa of dipteran larvae and infrequent anuran tadpoles. These ten taxa were never found together in a single pitcher and the mean species richness per pitcher was 4.0. Of the six taxa that could be assessed, all except Toxorhynchites spp. had a contagious distribution among the pitchers. Pitcher morphology and necromass accumulation explained only 15% of the variation in inquiline abundance among plants. I found little evidence for the existence of density-dependent interactions between inquiline species: a partial correlation analysis detected only one statistically significant pairwise relationship between the abundances of inquiline taxa, which was a positive association. Fourteen days after being emptied, pitchers contained an average of 9.6 inquilines. There was no evidence that the species composition of the infauna recolonising each pitcher was related to that of its pre-removal infauna.

    Accelerated sliding tests were carried out in the steels AISI 316, AISI 4140, AISI 1045 coated and AISI 4142 coated, in the dry and lubricated with contaminated oil with 10% SiO{sub 2} conditions. Each cylindrical counterbody with angular generatrix of polyurethane slid against a stationary metallic specimen. The contact pressure changed by increment of normal loads of 10,0 and 2,3 N, velocity of 0,91 m/s and distance of 12 km. The wear rates were calculated through of the mass variation from specimens after each test. The wear morphology was characterized by Optical and Scanning Electron Microscopy, where identified damages by abrasion at two and three bodies. The contaminated lubricant increase the wear rate due to action of the abrasive particles. (author)

    A transgenic line of the soybean 'Jack', Glycine max (L.) Merrill, expressing a synthetic cry1Ac gene from Bacillus thuringiensis variety kurstaki (Jack-Bt), was evaluated for resistance to four lepidopteran pests in the field. Jack-Bt and genotypes serving as susceptible and resistant controls were planted in field cages and artificially infested with larvae of corn earworm, Helicoverpa zea (Boddie), and velvetbean caterpillar, Anticarsia gemmatalis (Hübner), in 1996, 1997, and 1998, and also with soybean looper, Pseudoplusia includens (Walker), in 1996. Susceptible controls included Jack (1996-1998), 'Cobb' (1996), and Jack-HPH (1996). GatIR 81-296 was used as the resistant control in all 3 yr. Compared with untransformed Jack, Jack-Bt showed three to five times less defoliation from corn earworm and eight to nine times less damage from velvetbean caterpillar. Defoliation of GatIR 81-296 was intermediate between that of Jack and Jack-Bt for corn earworm, and similar to that of Jack for velveltbean caterpillar. Jack-Bt exhibited significant, but lower resistance to soybean looper. Jack-Bt also showed four times greater resistance than Jack to natural infestations of lesser cornstalk borer, Elasmopalpus lignosellus (Zeller), in conventional field plots at two locations in 1998. Data from these experiments suggest that expression of this cry1Ac construct in soybean should provide adequate levels of resistance to several lepidopteran pests under field conditions.

    Two different procedures, used for percutaneous augmentation of vertebral compression fractures were compared, with respect to height restoration and maintenance after cyclic loading. Additionally the impact of the cement volume used was investigated. Wedge compression fractures were created in 36 human cadavaric vertebrae (T10-L3). Twenty-seven vertebrae were treated with the SpineJack® with different cement volumes (maximum, intermediate, and no cement), and 9 vertebrae were treated with Balloon Kyphoplasty. Vertebral heights were measured pre- and postfracture as well as after treatment and loading. Cyclic loading was performed with 10,000cycles (1Hz, 100-600N). The average anterior height after restoration was 85.56% for Kyphoplasty; 96.20% for SpineJack® no cement; 93.44% for SpineJack® maximum and 96% for the SpineJack® intermediate group. The average central height after restoration was 93.89% for Kyphoplasty; 100.20% for SpineJack® no cement; 99.56% for SpineJack® maximum and 101.13% for the SpineJack® intermediate group. The average anterior height after cyclic loading was 85.33 % for Kyphoplasty; 87.30% in the SpineJack® no cement, 92% in the SpineJack® maximum and 87% in the SpineJack® intermediate group. The average central height after cyclic loading was 92% for Kyphoplasty; 93.80% in the SpineJack® no cement; 98.56% in the SpineJack® maximum and 94.25% in the SpineJack® intermediate group. Height restoration was significantly better for the SpineJack® group compared to Kyphoplasty. Height maintenance was dependent on the cement volume used. The group with the SpineJack® without cement nevertheless showed better results in height maintenance, yet the statistical significance could not be demonstrated. Copyright © 2013 Elsevier Ltd.

  17. COMPARATIVE EVALUATION OF AMBIENT FINE PARTICULATE MATTER (PM2.5) DATA OBTAINED FROM URBAN AND RURAL MONITORING SITES ALONG THE UPPER OHIO RIVER VALLEY

    Energy Technology Data Exchange (ETDEWEB)

    2002-04-30

    The report discusses the following conclusions: (1) The TEOM equipment performed as well as the sequential filter samplers in accounting for ambient PM{sub 2.5} levels; however, the FRM-obtained data was consistently lower than the averages from the TEOM/DRI-SFS measurements; (2) The trending in the PM{sub 2.5} levels was similar for Lawrenceville and Holbrook, which represent an urban and a rural site sixty-five miles apart. This implies that the PM{sub 2.5} levels appear to be impacted more by regional than by local effects; (3) The absolute median PM{sub 2.5} levels were slightly higher for Lawrenceville than for Holbrook, implying that local urban environmental contributions had a minor but measurable effect on total PM{sub 2.5} mass concentration; (4) PM{sub 2.5} and PM{sub 10} mass concentration levels were consistently higher in summer than in winter, with intermediate levels observed in the spring and fall; (5) Sulfate levels predominated in the speciation data obtained from both the Holbrook and the Lawrenceville sites during winter and summer intensive sampling. Sulfate level measured at Holbrook were higher than those taken at Lawrenceville regardless of the season; (6) Ammonium levels remained relatively constant between seasons and between sites; (7) Nitrate levels measured at Lawrenceville were higher than those measured at Holbrook during winter intensive sampling. Nitrate levels measured during the summer intensive period were found to be very low at both locations; (8) In general, the predominant inorganic fraction of the samples analyzed could be described as being composed of a mixture of ammonium bisulfate and ammonium sulfate with minor amounts of ammonium nitrate; (9) The PM10 fraction had a larger percentage of geological material and a smaller percentage of condensable material (ammonium bisulfate, ammonium sulfate, ammonium nitrate and total carbon species) than the PM{sub 2.5} fraction for samples collected in winter at Lawrenceville; and

O delineamento experimental utilizado foi o de blocos casualizados, em esquema fatorial 4 x 2, com quatro repetições. Os tratamentos foram compostos pela combinação entre quatro densidades de plantio da espécie vegetal feijão-de-porco (0; 8; 20; e 32 plantas m-2 e duas doses do trifloxysulfuron-sodium (0,00 e 15,00 g ha¹. Cinco dias após o preparo do solo, o trifloxysulfuron-sodium foi aplicado antes da semeadura da espécie fitorremediadora, a qual foi mantida na área por 65 dias. Após esse período a área experimental foi novamente sulcada e fertilizada sendo cultivado feijão (Phaseolus vulgaris L. cv. Vermelho Coimbra, espécie sensível ao trifloxysulfuron-sodium. Aos 45 dias após a semeadura do feijão avaliou-se a altura e a biomassa seca da parte aérea das plantas e ao final do ciclo da cultura, foram determinados o rendimento de grãos, o número de vagens por planta e o peso de 100 sementes. O cultivo prévio de C. ensiformis nas densidades populacionais de 8, 20 ou 32 plantas m-2 promoveu a remediação do herbicida. A densidade populacional mínima de C. ensiformis que proporciona maior rendimento de grãos à cultura do feijão é de 20 plantas m-2.This study aimed to evaluate the phytoremediation of the herbicide trifloxysulfuron-sodium in field, by Canavalia ensiformis cultivated in different populacional density. The experiment was arranged in a randomized block design, in a factorial scheme 4 x 2, with four replicates. The treatments consisted of the combination of four sowing densities (0; 8; 20; and 32 plants m-2 and two rates of trifloxysulfuron-sodium (0.00 and 15.00 g ha¹. Five days after soil preparation trifloxysulfuron-sodium was applied, before C. ensiformis sowing, which was kept for 65 days in the area. After this time the experimental area was furrowed, fertilized and bean (Phaseolus vulgaris cv. Vermelho Coimbra, specie sensitive to trifloxysulfuron-sodium, was cultivated. After 45 days of bean sowing, plant height and shoot dry biomass were evaluated and at the end of final cycle, grain yield, number of pods per plant and weight of 100 seeds, were determinated. Prior cultivation of C. ensiformis at densities of 8, 20 or 32 plants m-2 promoted herbicide remediation. The minimal of 20 plants m-2 of C. ensiformis provides the highest grain yield.

    We tested 3 models of Kirtland's warbler (Dendroica kirtlandii) habitat suitability during a period when we believe there was a surplus of good quality breeding habitat. A jack pine canopy-cover model was superior to 2 jack pine stem-density models in predicting Kirtland's warbler habitat use and non-use. Estimated density of birds in high...

  2. Trapping and Transportation of Adult and Juvenile Salmon in the Lower Umatilla River in Northeast Oregon: Umatilla River Basin Trap and Haul Program, October 1994-September 1995.

    Energy Technology Data Exchange (ETDEWEB)

    Zimmerman, Brian C.; Duke, Bill B.

    1995-09-01

    Threemile Falls Dam (Threemile Dam), located near the town of Umatilla, is the major collection and counting point for adult salmonids returning to the Umatilla River. Returning salmon and steelhead were collected at Threemile Dam from August 26, 1994 to June 27, 1995. A total of 1,531 summer steelhead (Oncorhynchus mykiss); 688 adult, 236 jack, and 368 subjack fall chinook (O. tshawvtscha); 984 adult and 62 jack coho (O. kisutch) ; and 388 adult and 108 jack spring chinook (O. tshawvtscha) were collected. All fish were trapped at the east bank facility. Of the fish collected, 971 summer steelhead; 581 adult and 27 jack fall chinook; 500 adult and 22 jack coho; and 363 adult and 61 jack spring chinook were hauled upstream from Threemile Dam. There were also 373 summer steelhead; 12 adult, 186 jack and 317 subjack fall chinook; 379 adult and 32 jack coho; and 15 adult and one jack spring chinook released at Threemile Dam. In addition, 154 summer steelhead were hauled to Bonifer and Minthorn for brood. The Westland Canal facility, located near the town of Echo, is the major collection point for outmigrating juvenile salmonids and steelhead kelts. The facility operated for a total of 179 days between December 2, 1994 and July 19, 1995. During that period, fish were bypassed back to the river 137 days and were trapped 42 days. Three steelhead kelts and an estimated 1,560 pounds of juvenile fish were transported from the Westland Canal trap to the Umatilla River boat ramp at rivermile 0.5. Approximately 98% of the fish transported this year were salmonids. The Threemile Dam west bank juvenile bypass began operating March 25, 1995 and was closed on June 16, 1995. The juvenile trap was operated by Oregon Department of Fish and Wildlife research personnel from April 1, 1995 through the summer to monitor juvenile outmigration.

  6. CARBON DIOXIDE FROM THE UNSEVERED VAGUS NERVE OF THE SNAKE.

    Science.gov (United States)

    Parker, G H

    1929-01-20

    1. The vagus nerve of the gopher-snake, Drymarchon corais couperi (Holbrook), discharges carbon dioxide at an average rate of 0.00234 mgm. of gas per gram of nerve per minute. The extremes were 0.0032 mgm. and 0.0017 mgm. 2. These rates were maintained as well when the nerve was separated from its central and its peripheral connections as when these connections were intact showing that the resting metabolism of nerve is a local operation and is not immediately dependent upon distant connections. 3. These observations also point to the conclusion that the passage of normal impulses over a nerve call for an increase of activity that is unobservable by the method employed and that must be small in amount compared with that produced by artificial stimulation.

  7. Correlations of the first and second derivatives of atmospheric CO2 with global surface temperature and the El Nino-Southern Oscillation respectively

    CERN Document Server

    Leggett, L M W

    2014-01-01

    Understanding current global climate requires an understanding of trends both in Earth's atmospheric temperature and the El Nino-Southern Oscillation (ENSO), a characteristic large-scale distribution of warm water in the tropical Pacific Ocean and the dominant mode of year-to-year climate variability (Holbrook et al. 2009. However, despite much effort, the average projection of current climate models has become statistically significantly different from the observed 21st century global surface temperature trend (Fyfe 2013)and has failed to reflect the statistically significant evidence that annual-mean global temperature has not risen in the 21st century (Fyfe 2013, Kosaka 2013). Modelling also provides a wide range of predictions for future ENSO variability, some showing an increase, others a decrease and some no change (Guilyardi, et al. 2012; Bellenger, 2013). Here we present correlations which include the current era and do not have these drawbacks. The correlations arise as follows. First it has been sho...

  8. “An Aristocracy of Talent”: The South Carolina Physician-Naturalists and their Times

    During the natural history movement of the 18th and early 19th centuries, Charleston as a center was rivaled in the United States only by Philadelphia, New York, and Boston. Prominent physician-naturalists included Alexander Garden (for whom the gardenia is named), John Edwards Holbrook (“father of American herpetology”), and Francis Peyre Porcher (whose Resources of Southern Fields and Forests helped Confederates compensate for drug shortages). The Charleston physician-naturalists belonged to an “aristocracy of talent” as distinguished from the “aristocracy of wealth” of lowcountry planters, who probably did more than any other group to perpetuate slavery and propel the South toward a disastrous civil war. None of the physician-naturalists actively opposed slavery or secession, a reminder that we are all prisoners of the prevailing paradigms and prejudices of our times. PMID:25125748

    2012-01-01

    The Burmese Python, Python bivittatus Kuhl 1820 (Squamata: Pythonidae), is indigenous to northern India,east to southern China, and south to Vietnam and a few islands in Indonesia (Barker and Barker 2008, Reed and Rodda 2009). This species has been introduced since at least 1979 in southern Florida, USA, where it likely began reproducing and became established during the 1980s (Meshaka et al. 2000, Snowet al. 2007b,Kraus 2009, Krysko et al. 2011, Willson et al. 2011). Python bivittatus has been documented in Florida consuming a variety of mammals and birds, and the American Alligator(Alligator mississippiensis) (Snowet al. 2007a, 2007b; Harvey et al. 2008; Rochford et al. 2010b; Holbrook and Chesnes 2011), many of which are protected species. Herein, we provide details on two of the largest known wild P. bivittatus in Florida to date, including current records on length,mass,clutch size, and diet.

    The in situ deformability of a highly jointed basalt rock mass was determined by the NX borehole jack method where the displacements of opposing curved platens were related to the applied hydraulic pressures, as well as by the modified Goodman jack method where the tangential strains on the borehole walls were related to the indiced tangential stresses. The modulus obtained by the modified Goodman jack method were much higher than those obtained by the NX borehole jack method. To explain the discrepancy, the influence of fractures and test variables such as depth, orientation, hole number and applied pressure on the calculated modulus of the rock mass were analyzed by factorial analysis and it was found that the orientations and depths of measurement has statistically significant effects. The in situ deformability values obtained by nonlinear regression analysis were also found comparable with other measurements and empirically predicted values for the basalt rock mass.

  16. The influence of nostalgia on consumer preference

    Full Text Available The main objectives of this study were to investigate the influence of nostalgia on consumer preference and to measure levels of nostalgia amongst multicultural groups. The study was based on past research in the field and used a modified version of a questionnaire developed by Holbrook (1993. A non-probability convenience sample (N = 504 was drawn from English, Afrikaans and Xhosa speaking consumers in the Eastern Cape. Field work was carried out by students of industrial psychology at the University of Port Elizabeth. Different levels of nostalgia emerged from the sample. These differences can be attributed to socio- demographic variables such as language, age, education and income. Results suggest that nostalgia not only influences consumer preference but also that nostalgic consumers represent an important market segment. Due to the complexity of the construct, marketers however need to be cautious when using nostalgia as a marketing tool. Opsomming Die hoof doelstellings van hierdie studie was om die invloed van nostalgia op verbruikersvoorkeure te ondersoek en vlakke van nostalgia by multikulturele groepe te meet. Die studie is gegrond op vorige navorsing in die veld en maak gebruik van 'n uitgebreide weergawe van 'n vraelys ontwikkel deur Holbrook (1993. 'n Nie-ewekansige gerieflikheidsteekproef (N = 504 is getrek uit Engels, Afrikaans en Xhosa-sprekende verbruikers in die Oos-Kaap. Veldwerk is uitgevoer deur bedryfsielkundestudente van die Universiteit van Port Elizabeth. Verskillende vlakke van nostalgia het na vore getree uit die steekproef. Hierdie verskille kan toegeskryf word aan sosio-demografiese veranderlikes soos taal, ouderdom, opvoeding en inkomste. Bevindinge suggereer dat nostalgia nie slegs verbruikersvoorkeure beihvloed nie maar ook dat nostalgiese verbruikers 'n belangrike marksegment verteenwoordig. Bemarkers moet egter versigting wees in die gebruik van nostalgia as 'n bemarkingsinstrument, as gevolg van die
