Method for Pipeline Section Retrieval for Overhaul with Complete Replacement

Earthworks required for overhaul or reconstruction of underground trunk pipelines with complete replacement of pipeline sections are one of the most labor-intensive. The paper suggests a new innovative method for retrieving a pipeline section to avoid using a single-bucket excavator along the entire section. The method reduces the duration of overhaul involving complete replacement of a worn-out pipeline section. The technology suggested is intended to improve the method of pipeline overhaul with complete pipeline section replacement. The study is focused on a set of devices used to retrieve a pipeline section. Based on a 3D model simulating the process flow of pipeline section retrieval, the related processes were observed and studied in depth, and the suggested innovative solutions were adapted as part of the repair and construction flow. The new method helps to, firstly, simplify the process of overhaul with complete replacement, secondly, improve the ecological situation in the construction area, and thirdly, upgrade the repair and construction flow outfitting. All pertinent equipment and devices can be used multiply, which is an indisputable advantage. The method is environmentally safe and suitable for all climate conditions, including complex ones. This innovative method allows retrieving underground pipeline sections regardless of their diameter. A broad use of this pipeline section retrieval method is ensured by a regular set of machinery and equipment available to nearly all repair and construction organizations and remotely controllable to reduce workforce needed for the above overhaul operations.

Noninvasive Follicular Tumor With Papillary-like Nuclear Features: A Practice Changer in Thyroid Pathology.

This article presents a review of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), including its separation from follicular variant of papillary carcinoma of the thyroid, its evolution, and current definition and pathologic characteristics. To emphasize the understanding of the concept of NIFTP as a neoplasm based on molecular analyses, its critical histopathologic features, the microscopic findings that exclude the diagnosis, and the importance of complete sectioning of the tumor to exclude neoplasms that should be diagnosed as carcinomas. Important distinctions are discussed including difficulties with literature that shows NIFTP with metastases, inadequacy of sectioning of the tumor, and lack of descriptive histology of the surrounding thyroid and possible other lesions. Review of articles in the English literature on NIFTP, as well as comparative papers showing differences and distinctions between this entity and papillary carcinomas. This article concludes that with the current state of knowledge on NIFTP with studies from all over the world, this entity is a low-risk neoplasm that, when diagnosed using appropriate criteria, should not be associated with metastatic or recurrent disease, at least on intermediate length of follow-up. This review includes discussion of multifocal NIFTP, as well as the recently defined micro-NIFTP (1 cm or less), and describes features of the tumor that remain to be studied and correlated with outcome: oncocytic variants of NIFTP, percentage of allowable solid areas of growth in the lesions, and definitions of true neoplastic papillae and hyperplastic ones and how these should influence the diagnosis of NIFTP.

Simulation and Experiment on Phase Equilibrium of Gas Hydrate Using the T-Type Pipe Confluence Model

A constraint of the development of gas hydrate is the phase change that may cause engineering losses in the mining process, which tends to be clogged in the section of well completion (sieve section: wellbore lifting section). The flow of gas hydrate in the well completion section was simplified using the T-type pipe confluence model in this paper. The temperature and pressure coupling model in the confluence section was derived first, followed by the use of the Fluent software to simulate its gradient changes in the T-type model. Then, the physical model and the experiment were designed to study the velocity changes. Finally, the contrast analysis between experiment and numerical simulation was carried out. Through the study of this paper, it is possible to prevent blockage in the well completion section during the process of depressurization, which can provide theoretical guidance for the control of pressure drop when gas hydrate is produced.

GEOMETRIA E CARATTERI STRATIGRAFICI DELLA SEQUENZA CENOMANIANA NEL BACINO LOMBARDO (ALPI MERIDIONALI)

The Cenomanian Sequence in the area between the lakes of Lecco and Iseo (Lombardy Basin, Southern Alps) represents a depositional unit bounded by two main unconformities and relative conformities. The unconformities progressively develop from SW to NE, with hiatuses spanning in age the Early Cenomanian and the Late Cenomanian-Turonian respectively.
 A complete section of the Cenomanian Sequence consists of Early Cenomanian red marls with pelagic turbidites and pebbly mudstones (Marne rosse) followed by two calcareous chaotic layers enclosing a succession of thin bedded, fine grained siliciclastic turbidites (Torbiditi Sottili), of Middle to Late Cenomanian age.
 The association of chaotic layers with the enclosed wedge shaped body of turbidites and the development of unconformities towards the north, point out that the Cenomanian basin developed in a mobile area where deposition was controlled by sinsedimentary tectonics. Moreover, the Cenomanian basin is, so far, the youngest Cretaceous basin clearly documented in the Southern Alps, oriented east-west, therefore crosswise to the structures related to the Jurassic rifting. Stratigraphic data strongly suggest that the tectonic evolution of the northern margin of the Cenomanian Lombardy Basin was generated by compression with the development of antiform structures.The sandstone unit pinches out towards the north and east, and thins more gradually towards the south. It represents a wedge shaped body, which parallels E-W paleocurrent trends and onlaps onto the northern margin of the Cenomanian basin. The two chaotic layers are basinally extended and show facies changes and thinning from north to south. They derived from sliding and slumping of the northern slope of the basin.

Stratigraphic scale and geological section

Research subject. The most frequently utilized fundamental notions in stratigraphy are discussed: concrete section, composite section, the stratigraphic scale, the biochronologic scale, the International Stratigraphic Scale. Materials and methods . The conventional content of these concepts is analyzed. The logical invalidity and negative consequences of the identification of subdivisions of the stratigraphic scale and subdivisions of a section are shown. The study of a section provides a way of obtaining information about the stratigraphic sequence of rock formation and the distribution of evidence of the events included in them, which are necessary for constructing stratigraphic scales. The close connection of the source of the actual data and results of its stratigraphic interpretation is the reason for the traditional identification of the subdivisions of the stratigraphic scale and subdivisions of a particular section. Results. The biochronologic scale inherits from a section the time sequence of occurrences of species of a certain group of organisms selected as the basis of a scale. However, special features of the evolutionary development of organisms do not depend on the composition of the containing deposits and the method of the separation of sedimentary rock sequences. This development makes it possible during the study of many specific sections to establish homotaxis in the distribution of fossils, i.e., to build a biochronologic scale. Thus, the understanding of the scale is a model of the biochronologic calculation of geological time. Like any model, a scale cannot be identical to what it simulates. Conclusion. A precise differentiation of the scale and a section is the basis for drawing correct stratigraphic conclusions. A zone is the smallest subdivision of the biostratigraphic scale. Zones are not divided into parts, are discrete (between adjacent zones there are no time passages), equivalent and are characterized by only the place which it occupies on the scale. The construction of a zone scale precedes the establishment of the material equivalent of the zone - of a stratozone - in the section. Any part of a stratozone is dated by the complete zone. The identification of the zonal scale with a sequence of stratozones in the section does not make it possible to understand the minimum dimensionality of a zone subdivision. The International Stratigraphic Scale (ISS) is defined, based on domestic stratigraphic codes and on foreign reference books, as a stratigraphic sequence of rocks (geological bodies) in total volume without passages and overlaps. In this treatment the ISS is not the scale, but is a complete (composite) geological section of the earth’s crust. The biostratigraphic scale serves as a tool of correlation. The ISS gives only the name of that subdivision, with which a concrete section is compared, and the geological age of the deposits of this section is designated by this name.

Effect of the Mid-Carboniferous event on the diversity of brachiopods in the Middle and Southern Urals

Research subject. In this study, the distribution of brachiopods in the Mid-Carboniferous boundary (MCB) sediments in the Middle and Southern Urals was investigated with the aim of determining the influence of the global Serpukhovian-Bashkirian minor mass extinction event on the diversity of these benthic organisms. Materials and methods . Brachiopods distributed over the most complete carbonate sections of the West-Uralian (Brazhka, Sokol, Martyanovo, Askyn, Lakly), Magnitogorskian (Khudolaz, Kalinino, Bolshoy Kizil) and the East-Uralian (Beklenishchevo, Cave gully, Brod-Klyuchiki, “Uralnerud-1” quarry) megazons were studies. Results. It was established that the diversity of the Giganto-productus-Striatifera brachiopod association reduced during the Late Serpukhovian, with the extinction of its dominant taxa having occurred during the Early and Middle Carboniferous boundary. During the Syuranian time of the Bashkirian Age, the Middle-Late Carboniferous Choristites association was formed. Further, in the Akavassian time, the diversity of brachiopods was restored. The consequences of the described event affected mainly the taxa of the species and genus taxonomic rank, and, to a much lesser extent, those of the family rank. On the western slope of the Urals, the maximum regression was recorded at the top of the Striatifera shell-rock layer of the Lower Carboniferous Staroutkinskian regional substage. On the eastern slope of the Urals, the brachiopod diversity characterizing the event in question can be clearly seen in the Late Serpukhovian. This dynamics was also manifested in the lowermost Pennsylvanian; however, it was obscured by the activation of regional tectonic factors. Conclusion. In the Middle and Southern Urals, the Mid-Carboniferous minor mass extinction event is recognized according to the dynamics of the genus and species diversity of bra-chiopods in the deposits of different facies.

18: Adherence to recommended practices when performing a risk-reducing bilateral salpingo-oophorectomy

To determine the adherence to the recommended practices for performing a risk-reducing bilateral salpingo-oophorectomy (RRBSO) as described by the American College of Obstetricians and Gynecologists and Society of Gynecologic Oncology. We sought to determine if adherence differed by type of training i.e., gynecologic oncologists versus benign gynecologists. Additionally, we aimed to determine the incidence of ovarian cancer diagnosed at the time of RRBSO in a large cohort of patients with a BRCA mutation. This descriptive, retrospective analysis was performed in an academic medical center. We examined the charts of 269 patients with a known BRCA mutation who underwent prophylactic RRBSO between July 2007 and September 2018. Surgery was performed either by a gynecologic oncologist or a benign gynecologist. Comparisons between groups were performed in the statistical analysis. Among 269 patients who underwent RRBSO, 220 were performed by gynecologic oncologists and 49 were performed by benign gynecologists. Washings were not performed in 5% of cases performed by gynecologic oncologists, and 37% of cases performed by benign gynecologists (p < 0.0001). Complete serial sectioning of the adnexa was not performed in 12% of cases performed by oncologists, and 13% of cases performed by benign gynecologists (p = 0.714). There were 8 cases (2.9%) of tubal or ovarian cancer diagnosed within this cohort. Of these cases, only 3 (1.1%) were diagnosed at time of surgery and met criteria for conversion to a staging procedure. Fifty-five percent of all patients also underwent concomitant hysterectomy. The incidence of ovarian cancer diagnosis at the time of RRBSO is low, and often not diagnosed at the time of surgery due to presence of only microscopic disease. For this reason, it may not be necessary for gynecologic oncologists to exclusively perform RRBSO procedures. However, this study also reveals that when this procedure is being performed by benign gynecologic surgeons, the recommended practices (washings and serial frozen section) are not routinely being followed. If benign gynecologic surgeons are to begin to routinely perform RRBSO, it is imperative to promote better adherence to these practices.

Sedimentology, stratigraphy and architecture of the Nicobar Fan (Bengal–Nicobar Fan System), Indian Ocean: Results from International Ocean Discovery Program Expedition 362

AbstractDrill sites in the southern Bay of Bengal at 3°N 91°E (International Ocean Discovery Program Expedition 362) have sampled for the first time a complete section of the Nicobar Fan and below to the oceanic crust. This generally overlooked part of the Bengal–Nicobar Fan System may provide new insights into uplift and denudation rates of the Himalayas and Tibetan Plateau. The Nicobar Fan comprises sediment gravity‐flow deposits, mostly turbidites, that alternate with hemipelagite drapes and pelagite intervals of varying thicknesses. The decimetre‐thick to metre‐thick oldest pre‐fan sediments (limestones/chalks) dated at 69 Ma are overlain by volcanic material and slowly accumulated pelagites (0.5 g cm−2 kyr−1). At Expedition 362 Site U1480, terrigenous input began in the early Miocene at ca 22.5 Ma as muds, overlain by very thin‐bedded and thin‐bedded muddy turbidites at ca 19.5 Ma. From 9.5 Ma, sand content and sediment supply sharply increase (from 1–5 to 10–50 g cm−2 kyr−1). Despite the abundant normal faulting in the Nicobar Fan compared with the Bengal Fan, it offers a better‐preserved and more homogeneous sedimentary record with fewer unconformities. The persistent connection between the two fans ceased at 0.28 Ma when the Nicobar Fan became inactive. The Nicobar Fan is a major sink for Himalaya‐derived material. This study presents integrated results of International Ocean Discovery Program Expedition 362 with older Deep Sea Drilling Project/Ocean Drilling Program/International Ocean Discovery Program sites that show that the Bengal–Nicobar Fan System experienced successive large‐scale avulsion processes that switched sediment supply between the Bengal Fan (middle Miocene and late Pleistocene) and the Nicobar Fan (late Miocene to early Pleistocene). A quantitative analysis of the submarine channels of the Nicobar Fan is also presented, including their stratigraphic frequency, showing that channel size/area and abundance peaked at ca 2 to 3 Ma, but with a distinct low at 3 to 7 Ma: the intervening stratigraphic [sub]unit was a time of reduced sediment accumulation rates.

Kinematic and mechanic evolution of the Andes buried front at the Boomerang Hills hydrocarbon province (Bolivia): Control exerted by the pre-Andean history

Abstract The Boomerang Hills are a hydrocarbon-rich region located in front of the Bolivian Andes, central South America, where the Andean chain bends forming the Bolivian Orocline. The geological interpretation of seismic (2D profiles and 3D volumes) and well data allowed us to generate a complete stratigraphic section, cross sections, maps and a 3D model, and to obtain the parameters to carry out a depth conversion and decompaction. A cross section and a 3D model were kinematically and mechanically restored, as well as decompacted, to decipher the evolution of this region through time. The southern Boomerang Hills are the buried frontal part of the Andes where thin-skinned contractional structures of Andean age (Late Cenozoic) predominate, whereas the northern Boomerang Hills belong to the Beni-Chaco Plain, where contractional structures are almost absent and thick-skinned extensional tectonics of pre-Andean age (Paleozoic, Mesozoic and Early Cenozoic) dominate. The buried frontal thrust of the Andes resulted from transpressional reactivation of a gravity-driven, extensional detachment developed along the slope of a basement high tilted during Paleozoic times. Thus, the thrust orientation, position, dimensions and type of structural termination were controlled by the extensional fault geometry, the Paleozoic mechanical stratigraphy, and the structural relationships between the Paleozoic cover and the basement.

Differential Contributions of the Quadriceps and Patellar Attachments of the Proximal Medial Patellar Restraints to Resisting Lateral Patellar Translation

To define the contributions of the of the medial patellofemoral ligament (MPFL) and medial quadriceps tendon femoral ligament (MQTFL) to lateral patellar translation as the knee moves through a 90° arc of motion. Six pairs of bilateral cadaveric knee specimens (12 knees) were dissected and potted in perfect lateral position using fluoroscopy. An eye screw was placed in the midpoint on the lateral aspect of the patella. Each knee underwent testing in 4 conditions after sequential sectioning: intact, lateral retinacular release, randomized MQTFL or MPFL sectioning, and complete proximal medial patellar restraint (PMPR) sectioning. With a custom machined jig, all knees were tested at 0, 10, 20, 30, 45, 60, and 90° of flexion on an MTS machine with 20N of lateral patellar force applied and displacement recorded. PMPR extensor mechanism insertion on all specimens was identified 50% on the quadriceps tendon and 50% on the proximal aspect of the medial patella. Isolated MPFL sectioning resulted in significantly increased lateral displacement compared to the lateral release state at all flexion angles tested except 0°. There was significantly increased lateral patellar displacement with complete sectioning compared with isolated proximal sectioning at all degrees of knee flexion except 0°. However, complete sectioning following isolated MPFL sectioning did not demonstrate significance at any angle. Compared with the MQTFL, the MPFL is primarily responsible for resistance to lateral patellar translation throughout a 0° to 90° arc of motion. The MPFL provides a similar resistance to lateral patellar displacement as the fully intact PMPR; however, the MQTFL may contribute to resistance in full extension. Proximal medial patellar restraint reconstruction techniques involving both the patellar and quadriceps insertion have been described; however, the unique contributions of the native anatomy to lateral patellar restraint have not been investigated.

Integral Cross Sections for Electron–Zinc Scattering over a Broad Energy Range (0.01–5000 eV)

We report results from the application of our optical potential and relativistic optical potential methods to electron–zinc scattering. The energy range of this study was 0.01–5000 eV, with original results for the summed discrete electronic-state integral excitation cross sections and total ionization cross sections being presented here. When combined with our earlier elastic scattering data [Marinković et al., Phys. Rev. A 99, 062702 (2019)], and the quite limited experimental and theoretical results for those processes from other groups, we critically assemble a recommended integral cross section database for electron–zinc scattering. Electron transport coefficients are subsequently calculated for reduced electric fields ranging from 0.1 to 1000 Td, using a multiterm solution of Boltzmann’s equation. Some differences with corresponding results from the earlier study of White et al. [J. Phys. D: Appl. Phys. 37, 3185 (2004)] were noted, indicating in part the necessity of having accurate and complete cross section data, over a wide energy regime, when undertaking such transport simulations.

Phase Equilibria in the System Ag-Cu-Si

The ternary alloy system Ag-Cu-Si was investigated in detail for the first time. The phase diagram was analysed by means of light optical microscopy, powder x-ray diffraction, differential thermal analysis (DTA) and scanning electron microscopy in combination with energy dispersive x-ray spectroscopy. The complete isothermal section at 650 °C was studied experimentally, and several additional samples were studied in order to obtain insight into phase equilibria with the high-temperature phases of the binary Cu-Si system. DTA studies in two vertical sections were used to determine ternary invariant phase reactions and to construct the ternary reaction scheme (Scheil diagram). A liquidus surface projection was constructed by combining these data with microstructure analysis of selected as-cast samples.

Application of ultrasound-guided balloon occlusion in cesarean section in 130 cases of sinister placenta previa

ObjectiveTo investigate the clinical utility of ultrasound-guided balloon occlusion in cesarean section in patients with sinister placenta previa. MethodsThe Interventional and Ultrasound Departments of the authors’ center assisted obstetrics to complete cesarean section in cases of sinister placenta previa. A total of 130 patients with implanted sinister placenta previa were diagnosed using obstetrical ultrasound and magnetic resonance imaging (MRI). Before cesarean section, the balloon was positioned in the bilateral radial or abdominal aorta. Immediately after delivery of the fetus, the balloon was temporarily filled to transiently seal the target vessel. According to the obstetrician’s assessment of hemostasis, the balloon was withdrawn at the appropriate time. Among the 130 patients, there was one case of abdominal aortic occlusion, with 129 cases blocked by the bilateral common iliac artery. ResultsAll 130 cases were successfully blocked, with an average blocking time of <15 ​min, while intraoperative blood loss was 800–1500 ​ml. ConclusionUltrasound-guided balloon blocking treatment before cesarean section can mitigate the dangers of placenta previa and significantly reduce blood loss with no exposure to X-ray radiation. Thus, the technique merits serious consideration.

Geochemical modelling of granitoid magma diversity at Capo Vaticano Promontory (Serre Batholith, southern Italy)

Late-Variscan metaluminous/weakly peraluminous (quartz-diorites and tonalites) and strongly peraluminous (two mica porphyritic granodiorites and granites) granitoids represent two magmatic associations making up the Capo Vaticano Promontory (central Calabria, Italy). They characterize a portion of a complete continental crustal section exposed in continuity from NW to SE in the adjacent Serre Batholith. In this paper, we deal with geochemical modelling trying to understand the evolutionary processes responsible for the CVP granitoid genesis. We have investigated the main processes such as fractional crystallization, variable entrainment of peritectic mineral phases in the melt (Stevens et al., 2007; Clemens and Stevens, 2012), restite-unmixing (White and Chappell, 1977) and magma mixing to explain the geochemical variability in major and trace elements of these magmatic suites. The quartz-diorites and tonalites, representing the deepest seated rocks, are constituted by various amount of Pl + Bt + Amph + Qtz. Bt-rich and Pl-rich quartz-diorite are characterized by cumulus of Bt and Pl, respectively. A multi-step articulated fractional crystallization process was able to reproduce the quartz-diorite/tonalitic trends. Starting from a tonalitic parental magma, three different cumulates were produced: a mafic (Bt-rich) cumulate (75 % Bt, 10 % Pl and 5 % Ap) after F = 10 %, a second cumulate composed by Pl (45 %), Bt (30 %) and Amph (5 %) after F = 20 % and Pl-rich quartz-diorite (60 % Pl, 20 % Bt and 20 % Amph) as the third cumulates, after F = 30 %. Among the source-related models, restitic unmixing could have played a minor role in the quartz-diorite and tonalite genesis, defining them as products derived from partial melting of I-type sources. Pl + Kfs + Qtz + Bt + Ms are the main phases constituting the porphyritic granodiorites and granites. A simple fractional crystallization from less evolved granodiorites sample (KA2) has reproduced the more evolved liquid composition (PA27), after F = 27 %. In addition, PAE modelling is consistent with partial melting of a metapelitic source with entrainment of 20 to 5 % vol. of a peritectic assemblage made of orthopyroxene and garnet.Magma mixing modelling with mafic end-members (a basalt, a basaltic andesite and the MME of CVP) excluded any additional contribution from the mantle.Finally, geochemical modelling highlights the fractional crystallization as the main responsible process in the CVP granitoids differentiation, whereas PAE and restite unmixing processes do not provide evidence about source contributions. This study supports the idea that granitoid rocks represent recycled crustal material in the Capo Vaticano Promontory.

Theoretical analysis of 8Li + 208Pb reaction and the critical angular momentum for complete fusion

In a theoretical approach, the complete and incomplete fusions are investigated by considering the Li8+208Pb reaction, within a three-body model where the projectile is described as n−7Li with binding energy εb. By decreasing εb from its known experimental value, the complete fusion is shown to have no meaningful dependence on such variations, whereas the incomplete fusion strongly depends on that. The complete and incomplete fusion cross sections are calculated by using a combination of both continuum-discretized coupled-channel and sum-rule models. To this end, an incident-energy dependent cut-off angular momentum Lc is first obtained by using the available complete fusion experimental data, within an approach which is extended to model results obtained for other incident-energies. An approximated fitted expression linking Lc to the well-known critical value Lcrit derived by Wilczyński (1973) [28] suggests that the sum-rule model could be generalized to energies around and below the Coulomb barrier.

Risk-reducing Bilateral Salpingo-oophorectomy: Assessing the Incidence of Occult Ovarian Cancer and Surgeon Adherence to Recommended Practices

This study aimed to determine the incidence of ovarian cancer diagnosed at the time of risk-reducing bilateral salpingo-oophorectomy in a large cohort of patients with a BRCA mutation. In addition, we aimed to determine the adherence to the recommended practices for performing a risk-reducing bilateral salpingo-oophorectomy as described by the American College of Obstetricians and Gynecologists and the Society of Gynecologic Oncology. We sought to determine if adherence differed by the type of training (i.e., gynecologic oncologists vs benign gynecologists). Descriptive, retrospective analysis. Academic medical center. Two hundred sixty-nine patients with a known BRCA mutation. Prophylactic risk-reducing bilateral salpingo-oophorectomy performed either by a gynecologic oncologist or a benign gynecologist between July 2007 and September 2018. Among 269 patients who underwent risk-reducing bilateral salpingo-oophorectomies, 220 procedures were performed by gynecologic oncologists, and 49 were performed by benign gynecologists. Washings were not performed in 5% of the procedures performed by gynecologic oncologists and 37% of the procedures performed by benign gynecologists (p <.001). Complete serial sectioning of the adnexa was not performed in 12% of the procedures performed by oncologists, and 13% of the procedures performed by benign gynecologists (p = .714). There were 8 cases (2.9%) of tubal or ovarian cancer diagnosed within this cohort. Of these cases, only 3 (1.1%) were diagnosed at the time of surgery and met the criteria for conversion to a staging procedure. Because the incidence of ovarian cancer diagnosis at the time of risk-reducing bilateral salpingo-oophorectomy is low and is often not diagnosed at the time of surgery owing to the presence of only microscopic disease, it may not be necessary for gynecologic oncologists to exclusively perform these procedures. However, this study also revealed that when this procedure is performed by benign gynecologic surgeons, some of the recommended practices are not routinely followed. If general gynecologic surgeons are to routinely perform risk-reducing bilateral salpingo-oophorectomies, it is important to promote better adherence to these practices.
