Abstract:

There is a deficit of commercially available paediatric airway models for anaesthesia airway management training, particularly for infant front-of-neck access and customised airway planning. Acknowledging this, we created a three-dimensional printed prototype for an affordable, high-fidelity training device, incorporating realistic tactile feedback, reproducibility and potential for modification for specific patient pathologies. Our model, created on a Stratasys Polyjet J750™ (Rehovot, Israel) printer, is a novel and useful educational tool in paediatric airway management, and we are pleased to share access to this resource with readers. Our work adds credence to three-dimensional printing as an accessible, reproducible and pluripotent technology in clinical anaesthesia.

Abstract:

The advent of 3D digital printers has led to the evolution of realistic anatomical organ shaped structures that are being currently used as experimental models for rehearsing and preparing complex surgical procedures by clinicians. However, the actual material properties are still far from being ideal, which necessitates the need to develop new materials and processing techniques for the next generation of 3D printers optimized for clinical applications. Recently, the voxelated soft matter technique has been introduced to provide a much broader range of materials and a profile much more like the actual organ that can be designed and fabricated voxel by voxel with high precision. For the practical applications of 3D voxelated materials, it is crucial to develop the novel high precision material manufacturing and characterization technique to control the mechanical properties that can be difficult using the conventional methods due to the complexity and the size of the combination of materials. Here we propose the non-destructive ultrasound effective density and bulk modulus imaging to evaluate 3D voxelated materials printed by J750 Digital Anatomy 3D Printer of Stratasys. Our method provides the design map of voxelated materials and substantially broadens the applications of 3D digital printing in the clinical research area.

Abstract:

Objectives: Three-dimensional (3D) printing has gained significance for human health-care applications in recent years. Some of these applications include obtaining models which mimic anatomical parts. One other parallel development in the biological research area is the development of 3D cell cultures. Such cultures are now becoming the material of choice for in vitro experiments, fast replacing the traditional adherent/monolayer 2D culture approaches. We present here, a method to obtain 3D prints of 3D aggregates of three human cancer cell lines. Such 3D prints can be useful models to understand solid tumor morphologies and also as effective teaching models. Materials and Methods: Photomicrographs of the 3D aggregates of the human cancer cell lines SiHa, MCF-7, and A549 (human cervical cancer, breast cancer, and non-small cell lung cancer cell lines, respectively) were obtained using inverted phase contrast microscopy. Conversion of normal jpeg images into 3D files was performed using the lithophane method and CAD files obtained. The CAD files thus generated were used to print the objects using the Stratasys Polyjet J750 3D Printer. Results: We could obtain 3D prints of SiHa, MCF-7, and A549 (human cervical cancer, breast cancer, and non-small cell lung cancer cell lines, respectively) 3D aggregates/spheroids. Conclusion: It is hoped that this approach will be useful for studying solid tumor morphologies in finer details. Furthermore, other benefits of such 3D prints would be in them being excellent models for teaching purposes.

Abstract:

Purpose PolyJet technology allows printing complex multi-material composite configurations using Voxel digital designs' capability, thus allowing rapid prototyping of 3D printed structural parts. This paper aims to investigate the processing and mechanical characteristics of composite material configurations formed from soft and hard materials with different distributions and sizes via voxel digital print design. Design/methodology/approach Voxels are extruded representations of pixels and represent different material information similar to each pixel representing colors in digital images. Each geometric region of a digitally designed part represented by a voxel can be printed with a different material. Multi-material composite part configurations were formed and rapidly prototyped using a PolyJet printer Stratasys J750. A design of experiments composite part configuration of a soft material (Tango Plus) within a hard material matrix (Vero Black) was studied. Composite structures with different hard and soft material distributions, but at the same volume fractions of hard and soft materials, were rapidly prototyped via PolyJet printing through developed Voxel digital printing designs. The tensile behavior of these formed composite material configurations was studied. Findings Processing and mechanical behavior characteristics depend on materials in different regions and their distributions. Tensile characterization obtained the fracture energy, tensile strength, modulus and failure strength of different hard-soft composite systems. Mechanical properties and behavior of all different composite material systems are compared. Practical implications Tensile characteristics correlate to digital voxel designs that play a critical role in additive manufacturing, in addition to the formed material composition and distributions. Originality/value Results clearly indicate that multi-material composite systems with various tensile mechanical properties could be created using voxel printing by engineering the design of material distributions, and sizes. The important parameters such as inclusion size and distribution can easily be controlled within all slices via voxel digital designs in PolyJet printing. Therefore, engineers and designers can manipulate entire morphology and material at each voxel level, and different prototype morphologies can be created with the same voxel digital design. In addition, difficulties from AM process with voxel printing for such material designs is addressed, and effective digital solutions were used for successful prototypes. Some of these difficulties are extra support material or printing the part with different dimension than it designed to achieve the final part dimension fidelity. Present work addressed and resolved such issued and provided cyber based software solutions using CAD and voxel discretization. All these increase broad adaptability of PolyJet AM in industry for prototyping and end-use.

Abstract:

In this article, I attempt to extend Krishna Bharadwaj’s insight on interlinked rural markets to the analysis of the interlinkages between paid and unpaid economic activities; in other words, between work and employment. Specifically, I argue that the gendered division of labour in India creates much greater involvement in unpaid labour for women, which in turn has direct and pervasive implications for their involvement in paid employment. Indeed, the interlinkage between the two is so profound that it is impossible to understand trends in one without assessing trends in the other. JEL Codes: J210, J220, J46, J710

Abstract:

Summary ‘First contact’ artefacts collected from aboriginal peoples by the early European explorers are now valuable in providing the only direct evidence for recent ‘Stone Age’ technologies which no longer exist. During the J770's Dr William Hunter collected many such artefacts for his private museum; most originated in the Pacific and in North America and had been collected by people who sailed with Captain James Cook. Since 1978 it has been possible to re-identify most of this early ethnographical material and to separate itfrom later acquisitions. To emphasise the archaeological relevance of this examples are described here from 18th century hunter-gatherer peoples (the Indians of Tierra delFuego, theNootka of British Columbia and the Eskimos of Alaska) and from stone-using farmers (the Maoris of New Zealand and the islanders of Hawaii). A list of the surviving early collection is given in microfiche.

Abstract:

Trends in Eastern Europe, with particular emphasis on Poland, are used in this article to analyse offshoring as a form of social dumping. Neoliberalisation and globalisation generate and utilise the mobility of both capital and labour. Meanwhile, labour migration is presenting a challenge to the observance of labour rights. Present-day methods of capital accumulation rely on the search for cheap labour and the relocation of production to territories that do not protect workers’ rights. Effective defence of labour rights must take place at the transnational level, where most capital is generated. Trade unions need to cross national borders in order to move social activity into this area. The defence of workers’ rights must go hand in hand with the struggle against nationalism and racist prejudices. In this context, migrant workers become one of the main potential driving forces of the modern global proletariat. JEL Codes: J610, J710, P1

Abstract:

Based on the material obtained from focus group interviews conducted during the COVID-19 pandemic, the article analyses the mechanisms used by employers towards employees, as well as the adaptation strategies applied by those in precarious employment in Poland. The authors’ considerations refer to anti-worker changes introduced under the pretext of the pandemic in the capitalist labour market: layoffs and cuts in wages, manifestations of discrimination against precarious workers and the potential attitudes of employee self-defence. The authors conclude that it is almost certain that under the conditions of post-pandemic capitalism, the number of the precariat will grow and the neoliberal system will want to retain as many of the anti-worker solutions introduced in the shadow of the pandemic as possible.

Abstract:

With more than 29 million confirmed cases of COVID-19 in the USA and 119 million cases worldwide, the pandemic has affected companies, households and the global economy. We explore the effect of the economic shock which resulted from this specific health event on labour market outcomes, and the changes in labour market disparities between ethnic groups and genders. The results provide evidence of an adverse effect of COVID-19 on labour market outcomes of all demographic groups, a widening gap between the employment prospects of minorities and whites, but no change in the earnings gaps between ethnic groups. We also do not find a deterioration of the differentials between genders, except the increase in the difference in the duration of unemployment between women and men with children. The findings have implications related to the priorities of policy decision-makers when implementing policies to combat ethnic and gender gaps in the labour market.

Abstract:

This article undertakes an examination of Bangladesh’s latest available Quarterly Labour Force Survey 2015–2016 data to draw in-depth insights on gender wage gap and wage discrimination in Bangladesh labour market. The mean wage decomposition shows that on average a woman in Bangladesh earns 12.2 per cent lower wage than a man, and about half of the wage gap can be explained by labour market discrimination against women. Quantile counterfactual decomposition shows that women are subject to higher wage penalty at the lower deciles of the wage distribution with the wage gap varying between 8.3 per cent and 19.4 per cent at different deciles. We have found that at lower deciles, a significant part of the gender wage gap is on account of the relatively larger presence of informal employment. Conditional quantile estimates further reveal that formally employed female workers earn higher wage than their male counterparts at the first decile but suffer from wage penalty at the top deciles.

Abstract:

This study examines the present status of women in the context of Electronic governance initiatives in Bangladesh. As a developing country, Bangladesh is stepping toward achieving E-governance where there is always a debate of the digital divide. Hence, this study tries to explore the challenges faced by women for access to and control over resources specifically the Information and Communication Technology tools or devices. It also aims to unveil the potentials of women's access and usage of such resources. This study employs survey data collected from study areas. Both urban and rural areas are chosen to get an overall scenario of women's status. This study is conducted in an inductive approach and findings are analyzed in a qualitative approach. The result shows that the status of women in access and usage of ICT varies in urban and rural areas due to some common constraints. The major findings of the study suggest that Information and Communication Technology has some potential for women empowerment which is explained as a case study. In this era of E-governance, most women are still facing gendered challenges such as lack of control over resources, awareness, education, and cybersecurity.

Abstract:

RésuméCent douze patients hospitalisés pour un épisode dépressif majeur (75% appartenant au sous-type mélancolique), d’origine endogène selon les critères de Newcastle, ont reçu du milnacipran (100 mg/24 h) ou de la clomipramine (150 mg/24 h) pendant une durée maximale de 3 mois lors d‘un essai réalisé en double-insu. Après exclusion d‘une observation du groupe clomipramine (arrêt à J3 pour nausées), restaient 111 observations exploitables pour l’analyse de l’activité : (milnacipran : 55 ; clomipramine: 56). Quatre-vingt-quatorze pour cent des patients ont atteint 4 semaines de traitement, 78% 8 semaines et 74% 12 semaines. Le nombre de sorties d’essai était comparable dans les 2 groupes, le pourcentage de celles qui étaient liées à un défaut d’activité étant identique (12,5%). A tous les temps étudiés, de J7 à J84, les évolutions obtenues sous milnacipran et sous clomipramine ont été comparables, pour les scores totaux des échelles de dépression de Hamilton (1967), de Montgomery et Asberg (1979) (MADRS) et de ralentissement de Widlocher (1981), mais aussi pour chacun des items de ces échelles. L’amélioration moyenne du score total de la MADRS a été, à partir d’un score initial de 38, de: 41% à J14; 66% à J28; 74% à J56; 76% à J84 sous milnacipran; 41% à J14; 59% à J28; 76% à J56; 83% à J84 sous clomipramine. Pour tous les paramètres étudiés, les niveaux de signification étaient particulièrement élevés (P = 0,3 à 0,9), indiquant des profils d’activité pharmacodynamique identiques pour le milnacipran et la clomipramine. L’appréciation du rapport bénéfice/risque (CG1-3), a été constamment favorable au milnacipran, avec des différences significatives à J14, J21, J28, J56 et J70: ces résultats favorables traduisaient la meilleure tolérance du milnacipran, notamment vis-à-vis des sécheresses buccales, des vertiges et des tremblements. Les activités antidépressives du milnacipran 100 mg et de la clomipramine 150 mg ont été identiques tout au long de cet essai de 3 mois. Le milnacipran a été mieux toléré que la clomipramine. Les résultats de cette étude ont confirmé ceux d‘études antérieures, en référence à d‘autres tricycliques ou à un placebo.

Full text

Abstract:

AbstractDuring deposition of the Jubaila-Arab-Hith sequences, the most important Arab-D reservoir, the Arab-C to A reservoirs and the Arab and Hith anhydrite seals were formed. The Kimmeridgian Jubaila-Arab-D transgression (MFS J70) restored and expanded the intrashelf basin geometry. The restored basin was filled by deeper subtidal Jubaila facies, which graded upwards to the Arab-D reservoir facies. In the late stages the Arab-D facies included both basin rim shoal facies and at least one large isolated shoal surrounded by ‘lagoonal’ intrashelf basin remnants interconnected by accessway channels. This differentiation was facilitated by local structural growth of a few metres. The Arab-D reservoir is overlain by the Arab-D anhydrite, deposited initially as gypsum in broad salinas, which blanketed the intrashelf basin region, forming the first major seal. By the end of Arab-D anhydrite deposition, the entire intrashelf basin area had been ﬁlled and transformed into a broad evaporite platform. Atop this platform, the Arab-C to -A (MFS J80-100) alternating shallow water carbonate and anhydrite (initially gypsum) intervals were deposited, ending regionally with the thick Hith Anhydrite Formation. The depositional setting for each of the main Jubaila-Arab-Hith sequences is reviewed and illustrated. The evolution of Jubaila-Arab-D reservoir models is discussed. Different interpretations of Jubaila-Arab-D-Hith sequences are compared, including the issue of whether the Arab carbonate-evaporite depositional sequence boundaries should be taken at the top of the carbonate intervals or the top of the anhydrites. Examples are included which illustrate how easterly palaeowind directions were an important factor controlling Arab-D facies variation. A scenario is presented to show how the Late Jurassic Tethys shelf uplift and low angle unconformity coupled with westward structural tilt were important. An alternating balance developed between the evolving land barrier and eustatic sea-level change during deposition of the Arab carbonate–evaporites and the Hith Anhydrite. Carbonates were deposited when the barrier was inundated and evaporites when the barrier was exposed and the area restricted and hypersaline. A major late Tithonian ﬂooding event (MFS J110) formed the top-Hith Manifa carbonate reservoir and brought open marine carbonate mud-rich deposition to the area, continuing without hiatus into the Early Cretaceous.

Abstract:

ABSTRACT This paper presents the calcareous nannofossil zonation of the Middle and Upper Jurassic of onshore Kuwait and formalizes current stratigraphic nomenclature. It also interprets the positions of the Jurassic Arabian Plate maximum flooding surfaces (MFS J10 to J110 of Sharland et al., 2001) and sequence boundaries in Kuwait, and correlates them to those in central Saudi Arabia outcrops. This study integrates data from about 400 core samples from 11 wells representing a nearly complete Middle to Upper Jurassic stratigraphic succession. Forty-two nannofossil species were identified using optical microscope techniques. The assemblage contains Tethyan nannofossil markers, which allow application of the Jurassic Tethyan nannofossil biozones. Six zones and five subzones, ranging in age from Middle Aalenian to Kimmeridgian, are established using first and last occurrence events of diagnostic calcareous nannofossil species. A chronostratigraphy of the studied formations is presented, using the revised formal stratigraphic nomenclature. The Marrat Formation is barren of nannofossils. Based on previous studies it is dated as Late Sinemurian–Early Aalenian and contains Middle Toarcian MFS J10. The overlying Dhruma Formation is Middle or Late Aalenian (Zone NJT 8c) or older, to Late Bajocian (Subzone NJT 10a), and contains Lower Bajocian MFS J20. The overlying Sargelu Formation consists of the Late Bajocian (Subzone NJT 10b) Sargelu-Dhruma Transition, and mostly barren Sargelu Limestone in which we place Lower Bathonian MFS J30 near its base. The lower part of the overlying Najmah Formation consists of the Najmah Shale, which is subdivided into three subunits: (1) barren Najmah-Sargelu Transition, (2) Late Bathonian to Middle Callovian (lower Zone NJT 12) Lower Najmah Shale, and (3) Middle Callovian to Middle Oxfordian (upper Zone NJT 12 to NJT 13b) Upper Najmah Shale. Middle Callovian MFS J40 and Middle Oxfordian MFS J50 are positioned near the base and top of the Upper Najmah Shale. The upper part of the Najmah Formation is represented by the Late Oxfordian (Subzone NJT 13b) Najmah Limestone, and is overlain by the Kimmeridgian (Zone NJT 14) Jubaila Formation. Early Kimmeridgian MFS J60 and Late Kimmeridgian MFS J70 are positioned near the base and top of the Jubaila Formation. The positions of Late Jurassic MFS J80, J90 and J100 are not constrained by our biostratigraphic data and are positioned in the Gotnia Formation. The Upper Tithonian MFS J110 and the Jurassic/Cretaceous boundary are positioned in the Makhul Formation.

Abstract:

ABSTRACT This Note presents a formal update to the Middle East Geologic Time Scale 2008 (ME GTS) for the Late Triassic and Jurassic rock units of Saudi Arabia. It reviews their lithostratigraphic nomenclature, ranks and stage assignments, and proposes names for third-order chrono-sequences as compiled and/or interpreted from the published literature. The review starts with the Late Triassic (Late Norian – Rhaetian) Minjur Sandstone of the Buraydah Group, with the Triassic – Jurassic (TrJ) boundary positioned at its top. The Minjur Sandstone consists of two units, here ranked as members, which are interpreted as the Late Norian – ?Early Rhaetian Lower Minjur Sequence (Lower Minjur Member) and ?Late Norian – Rhaetian Upper Minjur Sequence (Upper Minjur Member). The Early Jurassic Unconformity - Hiatus (Hettangian, Sinemurian and Pliensbachian stages) separates the Minjur Sandstone from the Toarcian Marrat Formation of the Jurassic Shaqra’ Group. The Shaqra’ Group consists of seven formations, from base-up: (1) Marrat Formation consisting of the Lower, Middle and Upper units, here ranked as members. (2) Dhruma Formation consisting of eight units (D1–D5, Wadi ad Dawasir “delta”, D6 and D7). The Dhruma units have been named in the literature as Balum Member (D1 and lower part of D2 units), Dhibi Limestone Member (upper part of D2 unit), Uwaynid Member (D3), Barrah Member (D4), Mishraq Member (D5), ‘Atash and Hisyan members (D7); the D6 and Wadi ad Dawasir “delta” units are not formally named as members. (3) Tuwaiq Mountain Limestone consisting of the Baladiyah (T1 unit), Mysiyah (T2 unit) and Daddiyah (T3 unit) members. (4) Hanifa Formation consisting of the Hawtah and Ulayyah members. (5) Jubaila Limestone with J1 and J2 units. (6) Arab Formation consisting of D to A members. (7) Hith Anhydrite consisting of Main Hith Anhydrite Member and Manifa Reservoir/Member. The seven formations of the Jurassic Shaqra’ Group are interpreted as 11 third-order chrono-sequences: (1) Early Toarcian Marrat Sequence B (Lower and Middle Marrat members) and Mid- to ?Late Toarcian Marrat Sequence A (Upper Marrat Member), the latter containing Arabian Plate maximum flooding surface MFS J10. (2) Bajocian Lower Dhruma Sequence (Balum Member and Dhibi Limestone), formed by the Balum and Dhibi subsequences, the former containing MFS J20. (3) Late Bajocian – Mid-Bathonian Dhruma Sequence B (Uwaynid, Barrah, Mishraq members, and Wadi ad Dawasir “delta” unit), with the Mishraq containing MFS J30. (4) Late Bathonian – early Mid-Callovian Dhruma Sequence A (unit D6, ‘Atash and Hisyan members), with the Hisyan containing MFS J40. (5) Mid- to Late Callovian Tuwaiq Sequence (Tuwaiq Mountain Limestone) containing an undesignated MFS at the base the Daddiyah Member (T3 unit). (6) Early and Mid-Oxfordian Hawtah Sequence (Hawtah Member of Hanifa Formation) containing MFS J50. (7) Late Oxfordian – ?Early Kimmeridgian Ulayyah Sequence (Ulayyah Member of Hanifa Formation) containing MFS J60. (8) Kimmeridgian Jubaila Sequence (Jubaila Limestone) containing MFS J70. (9) Arab-D Sequence (Arab-D Member inclusive of the Arab-D Anhydrite) containing an undesignated MFS in the Arab-D carbonate. (10) ?Kimmeridgian – ?Tithonian Arab-C and B Sequence (Arab C and B members) containing fourth-order MFS J80 and J90 in the lower carbonates of the members; and (11) ?Kimmeridgian – Tithonian Arab-A - Main Hith Sequence (Arab-A Member and Main Hith Anhydrite below the Manifa Reservoir/Member) containing fourth-order MFS J100 in the Arab-A Member. The Tithonian Manifa Member (upper part of the Hith Anhydrite Formation) is interpreted as heralding a transgression (fourth-order MFS J110), which deposited the Late Jurassic – Early Cretaceous Sulaiy Formation of the Thamama Group. The Jurassic – Cretaceous (JK) boundary is placed in the Sulaiy Formation by stratigraphic position. Based on the Geologic Time Scale GTS 2004 and Arabian Orbital Stratigraphy (AROS), the ages in million years before present of the sequence boundaries and maximum flooding surfaces are estimated for these chrono-sequences.

Abstract:

Abstract Purpose The purpose of this study is to evaluate biomechanical accuracy of 3D printed anatomical vessels using a material jetting printer (J750, Stratasys, Rehovot, Israel) by measuring distensibility via intravascular ultrasound. Materials and methods The test samples are 3D printed tubes to simulate arterial vessels (aorta, carotid artery, and coronary artery). Each vessel type is defined by design geometry of the vessel inner diameter and wall thickness. Vessel inner diameters are aorta = 30mm, carotid = 7mm, and coronary = 3mm. Vessel wall thickness are aorta = 3mm, carotid = 1.5mm, and coronary = 1mm. Each vessel type was printed in 3 different material options. Material options are user-selected from the J750 printer software graphical user interface as blood vessel wall anatomy elements in ‘compliant’, ‘slightly compliant’, and ‘rigid’ options. Three replicates of each vessel type were printed in each of the three selected material options, for a total of 27 models. The vessels were connected to a flow loop system where pressure was monitored via a pressure wire and cross-sectional area was measured with intravascular ultrasound (IVUS). Distensibility was calculated by comparing the % difference in cross-sectional area vs. pulse pressure to clinical literature values. Target clinical ranges for normal and diseased population distensibility are 10.3-44 % for the aorta, 5.1-10.1 % for carotid artery, and 0.5-6 % for coronary artery. Results Aorta test vessels had the most clinically representative distensibility when printed in user-selected ‘compliant’ and ‘slightly compliant’ material. All aorta test vessels of ‘compliant’ material (n = 3) and 2 of 3 ‘slightly compliant’ vessels evaluated were within target range. Carotid vessels were most clinically represented in distensibility when printed in ‘compliant’ and ‘slightly compliant’ material. For carotid test vessels, 2 of 3 ‘compliant’ material samples and 1 of 3 ‘slightly compliant’ material samples were within target range. Coronary arteries were most clinically represented in distensibility when printed in ‘slightly compliant’ and ‘rigid’ material. For coronary test vessels, 1 of 3 ‘slightly compliant’ materials and 3 of 3 ‘rigid’ material samples fell within target range. Conclusions This study suggests that advancements in materials and 3D printing technology introduced with the J750 Digital Anatomy 3D Printer can enable anatomical models with clinically relevant distensibility.

Abstract:

Abstract Background 3D printed patient-specific anatomical models have been applied clinically to orthopaedic care for surgical planning and patient education. The estimated cost and print time per model for 3D printers have not yet been compared with clinically representative models across multiple printing technologies. This study investigates six commercially-available 3D printers: Prusa i3 MK3S, Formlabs Form 2, Formlabs Form 3, LulzBot TAZ 6, Stratasys F370, and Stratasys J750 Digital Anatomy. Methods Seven representative orthopaedic standard tessellation models derived from CT scans were imported into the respective slicing software for each 3D printer. For each printer and corresponding print setting, the slicing software provides a print time and material use estimate. Material quantity was used to calculate estimated model cost. Print settings investigated were infill percentage, layer height, and model orientation on the print bed. The slicing software investigated are Cura LulzBot Edition 3.6.20, GrabCAD Print 1.43, PreForm 3.4.6, and PrusaSlicer 2.2.0. Results The effect of changing infill between 15% and 20% on estimated print time and material use was negligible. Orientation of the model has considerable impact on time and cost with worst-case differences being as much as 39.30% added print time and 34.56% added costs. Averaged across all investigated settings, horizontal model orientation on the print bed minimizes estimated print time for all 3D printers, while vertical model orientation minimizes cost with the exception of Stratasys J750 Digital Anatomy, in which horizontal orientation also minimized cost. Decreasing layer height for all investigated printers increased estimated print time and decreased estimated cost with the exception of Stratasys F370, in which cost increased. The difference in material cost was two orders of magnitude between the least and most-expensive printers. The difference in build rate (cm3/min) was one order of magnitude between the fastest and slowest printers. Conclusions All investigated 3D printers in this study have the potential for clinical utility. Print time and print cost are dependent on orientation of anatomy and the printers and settings selected. Cost-effective clinical 3D printing of anatomic models should consider an appropriate printer for the complexity of the anatomy and the experience of the printer technicians.

Abstract:

Abstract This chapter describes uppermost Middle Jurassic to lowermost Cretaceous second order stratigraphic sequences J40, J50, J60 and J70, and their component third order sequences, J42–J46, J52–J56, J62–J66 and J71–J76. The latest Callovian to Berriasian was an interval of significant tectonism, which led to the development of complex stratigraphy and highly variable successions, the elucidation of which is aided by the recognition of correlation of the J sequences. Marine sedimentation dominated the Callovian to Berriasian interval, with the development of multiple sandstone units, comprising reservoir units in many hydrocarbon fields, charged by marine source rocks (e.g., the Kimmeridge Clay Formation). Each of these units is subdivided and correlated by a succession of J sequences. Several sequences are renumbered (e.g., J54, J55, J65, J66), some sequence definitions are amended or their basal boundaries recalibrated chronostratigraphically (J52, J54, J72, J73, J74, J76) and new sequence subdivisions are recognised (J64a, J64b, J72a–J72c, J73a, J73b). Significant unconformities are recognised at the bases of the J54, J55, J62, J63, J64, J71 and J73 sequences. The top of J70 (J76) equates to the major “Base Cretaceous Unconformity” seismic sequence boundary.

Abstract:

Abstract Many of the stratigraphic sequences recognised in the wells correspond to mappable surfaces on seismic sections. Typically, however, sequences are only mappable seismically within the individual sub-basins, and seismic correlation between sub-basins, or across highs, is generally impossible without independent control from wells. Particularly prominent seismic sequence boundaries occur at near base J54 in the Inner Moray Firth (“Intra Oxfordian Event”) and Viking Graben (“Top Heather” in this area), base J62 (“Top Heather”, Moray Firth), base J66 (“top Lower Hot Shale”, Inner–Outer Moray Firth), base J71 (East Shetland Platform), base J73 (“Top Siltstone Member”, Moray Firth) and top J70/base K10 (“Base Cretaceous Unconformity, BCU”, basinwide).The intra Berriasian “BCU” is the most frequently mapped seismic horizon in the North Sea Basin in Jurassic studies.This surface, at the base of the Cromer Knoll Group, separates syn rift sediments from post rift successions above and marks a major shift in the tectonic evolution of the North Sea Basin.
