Abstract:

AbstractWe use repeat-track laser altimeter data from the Ice, Cloud and land Elevation Satellite (ICESat) to map the grounding zone (GZ) of the Filchner–Ronne Ice Shelf, Antarctica. Ice flexure in the GZ occurs as the ice shelf responds to ocean-height changes due primarily to tides. We have identified three ‘ice plains’, regions of low surface slope near the GZ where the ice is close to hydrostatic equilibrium: one on Institute Ice Stream; another to its east; and another west of Foundation Ice Stream. The vertical information from repeated ICESat tracks enables us to study the topography, state of flotation and flexure characteristics across these features. In regions of ephemeral grounding, tidal migration of the grounding line allows us to estimate bed slope (∼1–2 × 10−3). From these studies we develop a classification scheme for ice plains, expressed in terms of the evolution, or ‘life cycle’, of these features. A lightly grounded ice plain progresses to a state of ephemeral grounding as the ice sheet thins near the GZ. Once sufficient thinning has occurred, the ice plain becomes a fully floating, relict ice plain with an undulated surface topography similar to that of lightly grounded ice; we expect viscous relaxation to a smooth ice-shelf surface to occur over a timescale of decades. Our improved insight into ice-plain evolution suggests added complexity in modeling ice in the vicinity of the GZ, and a role for ice-plain observations as a guide to relatively rapid changes in ice-sheet mass balance.

Abstract:

AbstractWe present newly acquired airborne radar data showing ice thickness and surface elevation for Pine Island Glacier, Antarctica. These data, when combined with earlier measurements, suggest the presence of a lightly grounded area immediately above the grounding line of Pine Island Glacier. We identify this region as an “ice plain”. It lies close to the centre line of the glacier, has an elevation above buoyancy of <50 m and extends inland for >28 km. The upstream edge of the ice plain is defined by a “coupling line”. The configuration of the ice plain implies that nearby thinning of the ice stream would result in substantial grounding-line retreat. We suggest that the grounding-line retreat of Pine Island Glacier, observed between 1992 and 1996, probably commenced sometime after 1981.

Abstract BACKGROUND: Cerebrospinal fluid (CSF) infections associated with external ventricular drain (EVD) placement attract major consequences. Silver impregnation of catheters attempts to reduce infection. OBJECTIVE: To assess the efficacy of silver catheters against CSF infection. METHODS: We performed a randomized, controlled trial involving 2 neurosurgical centers (June 2005 to September 2009). A total of 356 patients requiring an EVD were assessed for eligibility; 325 patients were enrolled and randomized (167 plain, 158 silver); 278 patients were analyzed (140 plain, 138 silver). The primary outcome measure was CSF infection as defined by organisms seen on Gram stain or isolated by culture. Secondary outcome measures included ventriculoperitoneal (VP) shunting. RESULTS: There was a significant difference in infection risk between the 2 study arms: 21.4% (30/140) for plain catheters vs 12.3% (17/138) for silver catheters (P = .0427; 95% confidence interval [CI]: 1.015-3.713). Patients who had an EVD infection had more than double the risk of requiring a VP shunt compared with patients without an EVD infection (45.7% [21/46] vs 19.7% [45/229], respectively, P = .0002; 95% CI: 1.766-6.682). There was also a significant difference in VP shunt risk with infection: plain (55.2%; 16/29) vs the silver arm (29.4%; 5/17); P = .0244 (95% CI: 1.144-11.695). A multivariate analysis demonstrated that infection risk was increased by duration of EVD placement (odds ratio: 1.160), spontaneous intracranial hemorrhage (odds ratio 4.958) and decreased by silver catheters (odds ratio: 0.423). CONCLUSION: The study provides Class I evidence that silver-impregnated catheters reduce CSF infection.

Abstract:

Hiding in Plain Sight is an illustrated history of the former and present cinemas in the city of Leeds and an interactive website that engages Leeds residents in a participatory reminiscence project about cinemas and cinema-going. Launched in the summer of 2020, it is the most recent output of an ongoing cinema history research project at the Hyde Park Picture House, a much-loved 106 year-old Grade 2 listed independent cinema. The Hiding in Plain Sight project was one of a series of activities hosted by the organisation in line with their objective to engage as many people as possible with the cinema’s valuable heritage. The author of this paper, Dr Laura Ager, was employed by the Hyde Park Picture House as their Creative Engagement Officer between 2019 and 2020 and in this role she developed project’s framework and its research strategy. In this article she outlines the project’s origins and stages of development and considers how the methods used in the research phase have interacted with the design and production of the Hiding in Plain Sight website to give unexpected insights. She also reflects on some essential stages of project re-negotiation during the extraordinary and turbulent summer of 2020.

Abstract:

In this study, 4 layers of 5 mm thick slats obtained by sawing method from poplar wood were used. Plain woven GRFP with low density and grammage of 100 g/m2 (Type 1) and plain woven GRFP with high density and grammage of 200 g/m2 (Type 2) were placed and glued between each layer. Polyvinyl acetate (PVAc-D4), Polyurethane (PU) and dual-component Epoxy (L285-resin and H285-hardener) adhesives were used for gluing the layers. Strength values (bending and modulus of elasticity) between the obtained layers were investigated. As a result of the study, it was determined that epoxy glue has higher strength than polyurethane and polyvinyl acetate glues; Type 2 plain woven fabric has higher strength than Type 1 plain woven fabric; and parallel load to the glue line results in higher performance than perpendicular load to the glue line.

Abstract:

Detailed measurements of surface topography, ice motion, snow accumulation, and ice thickness were made in January 1974 and again in December 1984, along an 8 km stake network extending from the ice sheet, across the grounding line, and on to floating ice shelf in the mouth of slow-moving Ice Stream C, which flows into the eastern side of Ross Ice Shelf, Antarctica. During the 11 years between surveys, the grounding line retreated by approximately 300 m. This was caused by net thinning of the ice shelf, which we believe to be a response to the comparatively recent, major decrease in ice discharge from Ice Stream C. Farther inland, snow accumulation is not balanced by ice discharge, and the ice stream is growing progressively thicker. There is evidence that the adjacent Ice Stream B has slowed significantly over the last decade, and this may be an early indication that this fast-moving ice stream is about to enter a period of stagnation similar to that of Ice Stream C. Indeed, these large ice streams flowing from West Antarctica into Ross Ice Shelf may oscillate between periods of relative stagnation and major activity. During active periods, large areas of ice shelf thicken and run aground on seabed to form extensive “ice plains” in the mouth of the ice stream. Ultimately, these become too large to be pushed seaward by the ice stream, which then slows down and enters a period of stagnation. During this period, the grounding line of the ice plain retreats, as we observe today in the mouth of Ice Stream C, because nearby ice shelf, no longer compressed by ice-stream motion, progressively thins. At the same time, water within the deformable till beneath the ice starts to freeze on to the base of the ice stream, and snow accumulation progressively increases the ice thickness. A new phase of activity would be initiated when the increasing gravity potential of the ice stream exceeds the total resistance of the shrinking ice plain and the thinning layer of deformable till at the bed. This could occur rapidly if the effects of the shrinking ice plain outweigh those of the thinning (and therefore stiffening) till. Otherwise, the till layer would finally become completely frozen, and the ice stream would have to thicken sufficiently to initiate significant heating by internal deformation, followed by basal melting and finally saturation of an adequate thickness of till; this could take some thousands of years.

Abstract:

Previous research is equivocal on the most efficient, effective methods for displaying quantitative information in tables and graphs. Guidelines suggest different display types are more appropriate for certain purposes but not others. However, there is little empirical evidence to support the recommendations. This study examines several methods of displaying quantitative information (e.g., line graphs, bar charts, tables) factorially crossed with different kinds of data extraction questions (i.e., inquiries about trends, comparisons, and exact numerical quantities). Results showed that tables, bar grables (combined bar graph and table) and line grables produced the most accurate responses, and line graphs and bar charts produced the fastest responses across question types. Results are discussed with respect to prior theoretical work and the potential benefits of hybrid forms of quantitative data displays for multiple kinds of data extraction inquiries.

Abstract:

Coincident gravity, magnetotelluric (MT), and seismic reflection‐refraction surveys were conducted along a line traversing the boundary between the volcanic‐covered Eastern Snake River plain, Idaho, and the sediment‐covered Western overthrust belt, One‐dimensional MT and seismic refraction analysis away from the immediate boundary between sediments and volcanics successfully maps the depths to units of igneous and sedimentary—or metasedimentary—rock. Substantially different models of the volcanic‐covered terrain and of the sediment‐covered terrain are linked by a gravity anomaly and by an elongation and rotation of MT anisotropy ellipses which indicate a fault. Fault dip, depth extent, and motion are constrained by marked changes in the first‐arrival apparent velocities and by an electrical marker layer. The analysis shows that metasediments extend laterally at least 16 km beneath the volcanic cover. The two terrains are connected by a boundary zone which is a major normal fault.

Abstract:

Background Preservation of joint line height is an important factor in post-operative function after Total Knee Arthroplasty (TKA). This is the first study investigating the reliability of the novel Imperial Joint Line Congruency Measurement (IJLCM) technique for the assessment of joint line height using plain radiographs. Methods The reliability of two techniques used to measure joint line height on pre-operative and post-operative plain radiographs is presented. 120 patients that underwent TKA from 6 different international centres were included. Measurements were performed using each technique by two senior orthopaedic surgeons at two different timepoints (test-retest). Two undergraduate medical students performed joint line measurements using the most reproducible of the two techniques on 40 pre-operative and post-operative images to establish the reliability of the measurement technique. Results The IJLCM demonstrated an average absolute difference of 1.83mm (CI 1.56–2.10mm) and excellent inter and intra-rater reliability between senior orthopaedic surgeons (>0.92 (CI 0.88–0.94) when measuring joint line height on plain radiographs. Overall Crohnbach’s alpha over 0.92 confirmed internal consistency. Measurements performed using the control technique as previously described by Figgie et al. had an average absolute difference of 5.75mm (5.17–6.32mm). Comparison of measurements by senior orthopaedic surgeons and medical students using the IJLCM technique with ANOVA and student’s t-test demonstrated acceptable agreement and inter-rater reliability of >0.92 (0.87–0.95). Conclusion This study shows excellent accuracy, precision, and reliability of the novel IJLCM technique. Furthermore, excellent agreement between senior orthopaedic surgeons and medical students when using the IJLCM could be shown. The IJLCM technique is reliable for joint line assessment.

Abstract:

An experiment was carried out in the pot-house of botanical garden of Bangladesh Agricultural University (BAU), Mymensingh, during June to November, 2014 to investigate the effect of NaCl on growth, Na+ accumulation and K+: Na+ ratio in maize. Four maize genotypes namely BARI Maize 5, BARI Maize 7, Plain maize line and Mosaic maize line were tested against control, without providing any NaCl and salt stress, with NaCl to reach the soil salinity of 10 dS m-1. The experiment was laid out following CRD with four replicates. Under salt stress, relative reduction in shoot fresh masses were 22 and 77% in BARI Maize 5 and BARI Maize 7, whereas the magnitude of reduction was 136 and 155% in Mosaic maize line and Plain maize line, respectively. Seven days exposure to moderate salinity (10 dS m-1) seemed to have significantly reduced total fresh masses with the concomitant increase in Na+ concentrations but decrease in K+ concentrations and K+: Na+ ratios in both young and old shoots of BARI Maize 5, Plain maize line and Mosaic maize line. In contrast, BARI Maize 7 showed significant reduction in shoot fresh mass under salinity with the concomitant increase in shoot Na+ content but no significant changes in K+ concentrations and K+: Na+ ratios were observed under salinity. It seemed that young leaf of BARI maize 7 showed unaffected growth despite of higher accumulation of Na+. It may likely that BARI maize 7 sequestered incoming excess Na+ ions in the vacuole from the cytosol to combat deleterious effect of this ion to the cytoplasmic enzymes.Asian J. Med. Biol. Res.

Abstract:

Background. Identifying the factors related to low bone mineral density (BMD) can have significant implications for preventing hip fractures. The correlation between ascending aortic calcification and BMD has never been reported. Therefore, the purpose of the current study is to confirm the hypothesis that ascending aortic calcification can be used as a predictive factor for low BMD and to find a radiographic sign to show it. Method. Plain film and computed tomography (CT) images of the thorax were obtained from 91 patients with hip fractures. Using the images, the calcification line of the ascending aorta adjacent to the aortic arch was evaluated. A prominent calcification line confirmed by both plain film and CT was classified as +2. A line which was ambiguous on plain film but confirmed by CT was classified as +1. Cases with no calcification were categorized as 0 (control). We compared the classified score with the BMD and calculated the kappa coefficient to measure intraobserver reliabilities for this radiographic finding. Results. Twenty-eight patients showed a +2 line, twenty-four patients showed a +1 line, and thirty-nine patients showed 0 lines. The median BMD of each group was 0.37 for the +2 line, 0.45 for the +1 line, and 0.51 for the 0 line. The BMD for the +2 group was significantly lower than the others. The kappa coefficient was approximately 0.6 ( p < 0.01 ). Conclusion. The imaging finding of calcification of the ascending aorta might be considered as a potential surrogate marker of low BMD. In such subjects, BMD might be ordered for the confirmation of diagnosis of osteoporosis. Mini-Abstract. The Aortic Arch Tail Sign, a calcification line on the ascending aorta, was relevant to low BMD in the current study. BMD can be ordered for the confirmation of diagnosis of osteoporosis in a subject incidentally found to have ascending aorta calcification on X-ray or CT.

Abstract:

The phenomenon of lubricant cavitation in hydrodynamic bearings and its detrimental effects have been documented in many literatures. Collapse of vapor cavitation bubbles may cause erosion wear that limits the life of the bearings. The ability to detect the occurrence of vapor cavitation using a well established condition monitoring technique is essential for the equipment operator. An experiment was conducted to investigate the vibration characteristics of vapor cavitation in steadily loaded plain journal bearings. Vibration data were collected from the bearings operating under the influence of vapor cavitation. It is shown that, vapor cavitation exhibits distinct characteristics on the vibration plots. Low amplitude, forward and reverse 0.063X frequency components, and a series of harmonics with frequencies lower than 0.5X, are observed on the full spectrum. A unique waveform with the positive peak amplitude fluctuating above and below the zero axis line is also observed.

Abstract:

On the front-line, it is notoriously difficult to get employees to engage in knowledge management activities. It cannot be explained away as mere resistance; a complex range of organisational factors are at play which create obstacles to knowledge sharing and disenfranchise the workforce. Successful knowledge management ultimately hinges on employee participation. The mindset of ‘hiding knowledge management practices in plain sight’ is presented as an intervention strategy to boost employee engagement in knowledge management. This should appeal to knowledge management practitioners working in organisations who present lower levels of readiness, resistance, limited resources or imperatives to rapidly leverage critical knowledge.

Abstract:

This article investigates the plain language practices of professional writers in Quebec, using a survey. We contacted 55 professional writers and asked them to complete an online survey about how they apply plain language in their work, and the type of writing assistance they would find useful. We also asked 40 of those writers to carry out a simplification task to see what kind of simplifications they were actually making. If the feelings about the reality of the writers’ work is in line with the literature, opinions on plain language guidelines are not. Most writers in our survey find them useful and precise enough, and this contrasts with reported criticisms of such guides. In the simplification task, we noticed that writers focus on the overall understanding of the text, and not only on some linguistic characteristics (as shown in plain language guidelines). The more experienced the writer, the more changes they will make to visual/structural aspects or relational efficiency. Putting the focus on the reader’s needs is their main concern.

Abstract:

AbstractGeneral line rogue waves in the Mel’nikov equation are derived via the Hirota bilinear method, which are given in terms of determinants whose matrix elements have plain algebraic expressions. It is shown that fundamental rogue waves are line rogue waves, which arise from the constant background with a line profile and then disappear into the constant background again. By means of the regulation of free parameters, two subclass of nonfundamental rogue waves are generated, which are called as multirogue waves and higher-order rogue waves. The multirogue waves consist of several fundamental line rogue waves, which arise from the constant background and then decay back to the constant background. The higher-order rogue waves start from a localised lump and retreat back to it. The dynamical behaviours of these line rogue waves are demonstrated by the density and the three-dimensional figures.

Abstract:

Letournal and Judet classification of acetabular fracture is widely used. The classification is based on the identification of fracture lines on plain radiographs. Three-dimensional CT scan was claimed to give a better view of the fracture line. Our study showed that intraobserver reproducibility and interobserver reliability were almost the same when classification was done by using plain radiographs and 3D-CT scan. And 3D-CT scan did not increase either the interobserver reliability or the intraobserver reproducibility in classifying the fracture.

Full text

Abstract:

The objective of this feasibility study was to determine if the seismic reflection method could help to optimize placement of water‐quality monitoring wells near a radioactive storage facility. Seismic reflections from depths less than 30 m were recorded along a 500 m long line over a basalt, rhyolite, and sedimentary sequence in the Snake River Plain. Some shallow reflections at 40 to 50 ms on the field files are of exceptional quality with frequency exceeding 150 Hz. Reflections and refractions from selected seismograms along the line possess vastly different normal‐moveout (NMO) and apparent velocities as well as wavelet characteristics. Extreme variations in quality, seismic character, and reflector geometries observed on seismograms give the appearance of varying geologic settings and are uncommon for such short distances. Severe surgical muting was necessary for accurate velocity and statics analyses. The seismic reflection data show apparent structural lows in a sedimentary layer sandwiched between basalt flows. Interpreted structural lows must be verified by drilling before a monitoring plan can be fully developed. Similar shallow reflection surveys could also be used to improve deeper conventional seismic data in this and other basaltic terrain.

Abstract:

Protrusion acetabuli is the medial protrusion of the acetabulum in to the pelvic cavity, also known as arthrokatadysis, more common in females and classified etiologically as primary (idiopathic) and secondary forms. This is a 66-year-old female patient that presented for a plain radiograph of the pelvis and hip joints from a peripheral healthcare center on account of pain and inability to stand and move her waist and hips bilaterally, reduced movement of the legs and pain in the knees for more than three-year duration of onset. The plain radiograph of the pelvis and both hip joints demonstrate reduced density of the demonstrated bones, medial protrusion of the medial wall of the acetabulum in to the pelvic cavity bilaterally (distance between the imaginary Kohler’s line and medial acetabular wall is about 22mm bilaterally; Degree: III), obliteration of the hip joints bilaterally, thickening and sclerosis of the acetabular walls and other articular margins, subarticular cysts on the femur, acetabulum and pelvic bones. The patient had no coexisting condition like rheumatoid arthritis, Marfan’s syndrome and psoriatic arthritis. A diagnosis of bilateral idiopathic protrusio acetabuli was made. The patient was advised on bilateral total hip arthroplasty to improve the symptoms. We report a case of bilateral idiopathic protrusion acetabuli in an elderly female patient in order to describe the features of this condition radiographically.

Abstract:

Three new species of Gastromyzon from Brunei Darussalam, on the island of Borneo, are described from recent collections and from older museum specimens. Gastromyzon cranbrooki, new species, is superficially similar to G. borneensis, but differs in having a distinct secondary rostrum; body brown with 9–10 grey bars, head dorsum dark brown with thin grey reticulate pattern; and 56–60 scales on lateral line. Gastromyzon aeroides, new species, is similar to G. punctulatus, but differs in having the body uniform brown, dorsum uniform brown; head dorsum with very fine cream reticulate pattern (similar to a cream head with brown spots and blotches); dorsal, caudal and anal fins blue in life; and 47–65 scales in lateral line. Gastromyzon venustus, new species, is similar to G. pariclavis, but differs in having both the body and head dorsum plain brown; dorsal, caudal and anal fins red in life; and 58–63 scales in lateral line.

Abstract:

Background The lateral intercondylar ridge (resident's ridge) is considered to be an important landmark during anterior cruciate ligament reconstruction. Presently, no study exists describing the location of this vital landmark on plain radiographic images. Hypothesis Lateral intercondylar ridge location can be estimated on lateral plain film images. Study Design Descriptive laboratory study. Methods Lateral radiographic images were taken of 20 distal femora with metallic markers overlying the lateral intercondylar ridge. The length of Blumensaat's line and the distance from the anterior extent of Blumensaat's line to the point where the lateral intercondylar ridge intersects Blumensaat's line were measured. The ratio of these measurements was then determined (Blumensaat's-ridge ratio). The angle of the lateral intercondylar ridge with respect to Blumensaat's line (Blumensaat's-ridge angle) was also determined. Results The mean length of Blumensaat's line was 32.1 mm (95% confidence interval, 31.0–33.2 mm). The mean distance from the anterior extent of Blumensaat's line to the point where the lateral intercondylar ridge intersects Blumensaat's line was 25.3 mm (95% confidence interval, 24.3–26.3 mm). The mean Blumensaat's-ridge ratio was 0.79 (95% confidence interval, 0.77–0.81). The mean Blumensaat's-ridge angle was 75.5° (95% confidence interval, 72.0°–79.1°). Conclusion The lateral intercondylar ridge intersects Blumensaat's line at a point defined by multiplying the Blumensaat's line length by 0.79. From this point, the ridge runs at a 75.5° angle with respect to Blumensaat's line. Clinical Relevance Awareness of the radiographic location of the lateral intercondylar ridge may help confirm accurate tunnel placement when arthroscopic positioning is in doubt. Furthermore, femoral tunnel position can be quickly and accurately assessed in the outpatient setting in patients with unsatisfactory outcomes after anterior cruciate ligament reconstruction.

Abstract:

This paper concerns the superlative forms of the words many, much, few, and little, and their equivalents in German, Dutch, Swedish, Norwegian, Danish, Dalecarlian, Icelandic, and Faroese. It demon-strates that every possible relationship between definiteness marking and interpretation is attested. It also demonstrates that different kinds of agreement mismatches are found under relative and proportional readings. One consistent pattern is that under a relative interpretation, quantity superlatives with adverbial morphology show neuter singular agreement even if the target noun is plural. In contrast, under a proportional interpretation, quantity superlatives always agree in number. This evidence is taken to show that quantity superlatives are not structurally analogous to quality superlatives such as tallest on either a relative or a proportional reading; however, depending on their interpretation, quantity superlatives depart from a plain attributive structure in different ways. On relative readings, they can have a structure akin to that of pseudo-partitives (as in two liters of milk), while on proportional readings, they tend to have a quantificational structure, sometimes involving a true partitive (as in some of the children). Furthermore, I suggest that the agreement features of a quantity superlative depend on the domain from which the target is drawn (the Target-Domain Hypothesis).

Abstract:

Colonialism has its impact on Indian politics and society even after the colonialism. Pre-colonial Assam was able to maintain its independent status till 1826. After incorporating into the company’s holdings, colonialists gradually extended their controls to the hill areas surrounding the Assam and Bengal plains. Subsequent to annexing the hills, the areas were designated as “tribal” areas and continued to be ruled as a distinct administrative regime. However, the strategy of divide and rule system had fundamentally changed the practices of both hills and the plains. For segregating the hills from the plains, a line was drawn, known as Inner line of 1873. The gradual separation and sharpening of identity had led to the formation of ‘Bordoloi Sub-committee to render autonomy to the hill people. However, the recommendation made by the ‘Bordoloi Sub-committee’ were not able to fulfil the aspirations of the hill tribes, and they started demanding for more autonomy in the form of statehood, backed by insurgent activities, which paved the way for the reorganisation of Assam. And in the present juncture, the Plain tribes of Assam have been demanding for re-reorganisation of Assam. Hence, this study specifies the colonial subjectivity and subjugation and its consequences to new equations of contemporary politics.

Abstract:

Aim: There is an increasing incidence of hip fracture with associated morbidity and mortality making accurate and timely diagnosis essential. The aim of this study was to compare computed tomography (CT) and magnetic resonance imaging (MRI) to ascertain the optimum second-line investigation in cases where plain radiograph is not diagnostic. Material and Methods: Using the radiology information system, a total of 168 patients were identified with the suspected occult neck of femur fractures over 24 months who had undergone CT or MRI as second-line investigation. All relevant imaging was reviewed and diagnosis, any third-line or follow-up imaging was documented. Results: About 16% of patients undergoing CT as second-line test had proven originally occult femoral neck fractures on plain radiograph compared with 13% of those having MRI. About 13% of patients underwent MRI following CT and in 1/13 case MRI detected an occult fracture that had not been detected on CT. The remaining 11 patients were either negative or MRI proved CT suspicions of fracture when extra diagnostic certainty was requested by the surgeons. CT detected more non femoral pelvic fractures 47% versus 37%. Conclusion: CT and MRI are comparable at detecting occult femoral neck fractures. Given the increased availability, improved patient tolerance and speed of CT imaging, we advocate its use as the main second-line imaging modality. MRI remains a valuable problem-solving tool in a select few cases following review with a musculoskeletal radiologist.

Full text

Abstract:

Unreinforced hollow concrete masonry walls could be used to construct basements if strengthened to resist the lateral load. Two face-shell-bedded concrete masonry walls were constructed, 3 m high by 6 m long. As a simple strengthening technique, one wall was sprayed with glass-fibre-reinforced polymer (GFRP) on one side to a nominal average thickness of 5 mm. The walls were subjected to distributed point loading simulating increasing pressure from top to bottom of the wall. Support conditions were applied to simulate the walls being part of a basement. The plain wall failed with a failure line cracking pattern at a lateral load of 44 kN. The sprayed wall failed in a much more brittle fashion when the load reached 330 kN. The GFRP suffered a mode III tear at the bottom course. The results indicate that spraying a plain masonry wall with GFRP increases its ability to resist lateral load considerably, and that the process could be improved in terms of both the thickness of the layer and the area of wall covered to achieve a specific target. The two walls were analyzed using the yield-line, fracture-line, and failure-line methods. The failure-line method was improved by accounting for the stiffness orthotropy of masonry and gave the most accurate prediction of these plastic design methods. A finite element model of the masonry provided the most accurate prediction of capacity.

Abstract:

Background The standard imaging procedure for suspected nasal fractures has been radiography (XR). However, its usefulness for clinical decision making is highly controversial. High-resolution ultrasonography now offers a promising new diagnostic imaging option. In this study we compared the diagnostic value of high-resolution ultrasonography and conventional XR in the evaluation of suspected nasal fractures. Methods A prospective single-blinded study was performed. Ultrasound (US) and XR findings in 80 patients with suspected nasal fractures were compared with the definite clinical diagnosis with respect to sensitivity, specificity, and accuracy. Results For detection of fractures of the nasal dorsum, both modalities had high sensitivity (98 and 88% for US and XR, respectively) and specificity (95% for both US and XR). In lateral nasal wall fractures, specificity was higher for XR (75% versus 94%). Sensitivity was significantly higher for the US examination (98% versus 28%). In summary, the accuracy was higher for US. Conclusion When available, US should be the first-line imaging procedure in the evaluation of nasal fractures.

Abstract:

AbstractPine Island Glacier, flowing into the Amundsen Sea from West Antarctica, thinned substantially during the 1990s, its grounding line receded by several km, and its velocity increased by >10% to values approaching 3 km a–1. Here, we use these observations, together with estimates of ice thickness and surface strain rates, to estimate the perturbation in forces resisting ice flow compatible with the observations. The analysis assumes that such perturbations are transmitted far upstream from where they originate, and that creep response to the perturbations can be described by equations similar to those that govern ice-shelf creep. It indicates that observed acceleration between 1996 and 2000 could have been caused by progressive ungrounding within the most seaward 25 km ‘ice plain’ of the grounded glacier. Earlier retreat and thinning of the glacier’s floating ice shelf may have provided the conditions that initiated ungrounding of the ice plain. Our analysis indicates that continued ice-plain thinning at the current rate of about 2 ma–1 will result in a velocity increase by 1 km a–1 within the next 11 years as the ice plain becomes totally ungrounded.

The authors see these tactics as an innovative means of popularization of science and education development in the professional sphere. These tactics help specialists explain certain terms and concepts of a professional domain. As a research material, the authors chose on-line legal texts that are in demand for wide readership. The following tactics have been revealed: choosing sub-technical terms or spoke equivalents, using plain grammar structures and short understandable sentences, explication of professional presuppositions, quoting and referencing to the legal acts, using non-verbal elements. The authors used the National Corpus of the Russian Language for the comparison of the usage of professional terms and their spoken equivalents. The findings of the research can be used for linguistic and pragmatic simplification of legal texts (on-line and off-line), and professional texts of other professional domains. The findings of this research are essential for preparation of educational materials for higher professional institutions.

Abstract:

In railway turnout areas, vertical and horizontal structure irregularities, including geometry and stiffness, result in vibration amplification during the passage of trains. These vibrations can then spread to the surrounding environment. A steel spring floating slab track may be used to control such vibrations, especially in metro-type urban railways. An experimental study was conducted to investigate the vibration-mitigating effects of the floating slab track in turnout areas, and the results were compared with the performance of a regular slab track. Four test cases (consisting of six test sections) were selected: a floating slab track in the turnout zone (consisting of a switch rail section and a nose rail section), a floating slab track in the plain line, a slab track in the turnout zone (consisting of a switch rail section and a nose rail section), and a slab track in the plain line. The vibration characteristics of the floating slab track in the plain line and in the turnout were calculated to explain the test results. The test results indicate that when trains pass across the floating slab track in the turnout zone, the vertical vibration response is close to the horizontal response on the switch rail sections. The use of floating slab track can effectively reduce this vertical vibration. However, the vertical vibration response is much larger than the horizontal response on the nose rail sections of the turnout zone. When the floating slab track is used in these turnout zones, the vertical vibration of the rail decreases while the horizontal vibration increases. Compared to sections using the regular slab track in the turnout zone, the vibration of the floating slab track segments in the turnout zone is shown to be exacerbated, although the vibration level at the adjacent tunnel wall is effectively reduced.

Abstract:

Abstract. A study of the effects of human modification of a coastal plain mainly involving land reclamation and flood protection is proposed. The approach involves historical, geomorphological and hydrological data as a whole, taking into account the equilibrium of rivers, plains and coastal areas. The test area, a telling example of profound economic and social transformation of a coastal plain, is the Piana di Sibari (Calabria, southern Italy), subject to major human modifications over the last 150 years. The study area, at most 300 m a.s.l., is 450 km2 wide and comprises 24 hydrographic basins. The approach is based on the creation and analysis of four databases: 1) a historical series of geo-coded flood damage (DAMAGES database), concerning damaging floods which occurred over the past few centuries in the study area; 2) a geocoded series of protection works for land reclamation, protection from floods and improvement of soil stability in steep areas (WORKS database), gathered from the archives of the agencies that carried out the works, organized in a GIS-format; 3) a historical series of maximum flood discharges and extreme rainy events (HYMAX database) aimed at defining the trends of occurrence and the intensity of flooding; 4) a coastal line position and migration over time (COASTAL database), created using mainly literature data based on discontinuous data such as historical maps and images. The work describes the complex succession of floods, protection and reclamation works, human transformation of the plain and major land use changes over the last two centuries in the test area. The new characteristics of the plain and its modifications, including major engineering works, land-use transformation and urbanisation, are illustrated. The damaging floods of the last 200 years, the modifications of runoff and flooding due to works built over the basins, hydrological data and the records concerning coastal modifications were used to create specific databases and a GIS in which these data can be analyzed by typology, location and extension. The proposed approach highlights the high degree of correlation between drainage basin management, mainly in terms of increasing protection from natural hazards, and anthropogenic development in a broad coastal plain.

Abstract:

AbstractThe IPCC climate models predict, for the Central Europe, are for climate changes, being seen variability of temperature, with a growing trend of 1-2,5° C (with 1° C for alpine zone – Carpathians and 2-2,5° C for plains). Current observations in the Romanian plain are not consistent, with an existence of a multiannual variability of temperature and precipitations depending on cyclonal and anti-ciclonal activity. The research is based on calculation of reduced centered index, also the graphical chronological method in information processing (MGCTI) of „Bertin Matrix” type, to show current trends of the spatio-temporal variability of precipitation in the context of global climate change. These are in line with the movement of air masses in Europe in general, and implicitly in Romania, with particular regard to the southern region of the country where the Romanian Plain. The variability of short-term global climate is generally associated with coupling phases of oceanic and atmospheric phenomena including El Niño Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO). While El Niño Southern Oscillation (ENSO) affects climate variability in the world, the North Atlantic Oscillation (NAO) is the climate model dominant in the North Atlantic region. The latter cyclic oscillation whose role is still under debate could explain the variability of rainfall in much of the, central Europe area, and support the hypothesis of a return of the rains marking the end of years of drought in Romanian plain. Faced with such great changes that today affect the central Europe region and given the complexity of spatial and temporal dimensions of the climatic signal, a more thorough research of causes and retroactions would allow for a better understanding of the mechanisms behind this new trend.

A short-cut review was carried out to establish whether CT or MRI is better at detecting an occult hip fracture. Six studies were directly relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The clinical bottom line is that CT is a valid first-line investigation for a suspected plain X-ray occult hip fracture. If clinical suspicion remains after a negative CT scan, then MRI should be used.
