Abstract:
The present study focuses on the effect of nozzle exit inclination on the mixing characteristics of Mach 2.17 overexpanded jets at the NPR 5, NPR 6 and NPR 7, using commercial software package ANSYS Fluent. The convergent-divergent nozzles, investigated are circular nozzle and bevel nozzle with bevel angle 300, and bevel angel 450. The nozzles are constructed with equal throat-to-exit area ratio, in order to maintain uniform Mach number at the nozzle exit. From the results, it was found that, the bevelled nozzles effectively reduce the jet core as much as 46%, indicating enhanced jet mixing. It was also observed that at lower NPR, i.e., at NPR 5, the Bevel30 nozzle is found superior over Bevel45 and circular nozzle and at the intermediate NPR, both of the Bevel30 and Bevel45 nozzle reduces the jet core with the same rate. However, at highest NPR of the present study, the Bevel45 nozzle exhibits the highest mixing enhancement. An early axis switching is seen for the Bevel30 jet at NPR 5 and for the Bevel45 jet at NPR 7.

Abstract:
Abstract Root end resections play an important role in the success of periapical surgery. Beveling of the root end resections can vary significantly depending on the surgical technique, the root and canal morphology. The intention of this article was to clinically assess the root resections bevels and to estimate their relation to applied periapical surgeries. A prospective clinical study consisted of sixty periapical surgeries performed on teeth with chronic periapical lesions. Thirty periapical surgeries were performed in a conventional manner, while thirty were contemporary ultrasonic surgeries. Following the completion of strictly planned and performed intraoperative procedures, the resection bevels were assessed. To obtain the real bevel angles a compass was used. Root resections were significantly less beveled in all teeth operated with contemporary ultrasonic surgery, with mean values between 2.1° to 7.8°. The number of roots and their dilacerations didn’t influence the root resection bevel. For comparison, root resections were significantly beveled in all conventionally operated teeth, with mean values of 46°. Due to the technical limitations of the conventional periapical surgery, mandibular premolars were exclusively operated with ultrasonic periapical surgery, with mean values of resection bevel not exceeding 20.7°. Significantly lesser resection bevel associated with ultrasonic periapical surgery contributes to root preservation and favorable surgical outcome.

Zodra na het vaststellen van een jaarrekening wordt ontdekt dat de jaarrekening in ernstige mate tekortschiet in het geven van inzicht, verplicht de wet het bestuur om hiervan mededeling te doen bij het Handelsregister. Deze mededelingen komen in de praktijk echter relatief weinig voor. Een mogelijke verklaring hiervoor is dat men in het zicht van het publiceren van de volgende jaarrekening waarin deze fout al wordt vermeld, afziet van deze mededeling. Indien de jaarrekening inderdaad op zeer korte termijn wordt gepubliceerd past dit bij het doel van deze wettelijke bepaling. Een snelle publicatie van de volgende jaarrekening is bovendien aan te bevelen omdat het opvragen van désaveuverklaringen in de praktijk moeizaam blijkt.

Abstract:
Abstract Aim This double-blind randomized clinical trial compared the performance of posterior composite restorations with and without bevel. Methods and Materials Thirteen volunteers requiring at least two posterior Class II restorations were selected. Twenty-nine cavity preparations were performed, comprising 14 without bevel (butt joint) and 15 with marginal beveling. All cavities were restored with a simplified adhesive system (Adper Single Bond, 3M ESPE, St. Paul, Minnesota, USA) and composite resin (Filtek P60, 3M ESPE, St. Paul, Minnesota, USA). A halogen light-curing unit (XL 3000, 3M ESPE, St. Paul, Minnesota, USA) was used throughout the study. Restorations were polished immediately. Analysis was carried out at baseline and after six months by a calibrated evaluator (kappa), according to FDI criteria. Results The results were statistically analyzed by Kruskal-Wallis and Mann-Whitney tests (p<0.05). Beveled and nonbeveled restorations performed similarly after six months in relation to fractures and retention, marginal adaptation, postoperative hypersensitivity, recurrence of caries, surface luster, and anatomic form. However, for surface and marginal staining, beveled restorations showed significantly better performance than butt joint restorations (p<0.05). Conclusion Restorations performed were acceptable after six months, but beveled restorations showed less marginal staining than nonbeveled restorations. Clinical Significance Bevel used in posterior composite restorations decreased the surface and marginal staining, in six-month evaluations.

Abstract:
AIM: The aim of this study was to evaluate two composite restorations (conventional methacrylate-based and low shrinkage-based silorane), associated or not to beveling and incremental technique, in relation to the microleakage and marginal gap formation tests. MATERIAL AND METHODS: 30 sound human molars had their mesial and distal surfaces prepared with and without bevel. The teeth were divided into six groups according to the type of resin (conventional nanofilled or silorane resin), and restorative filling technique (incremental technique or builk). Microleakage and marginal gap formation data were statistically analyzed by Kruskal-Wallis and Chi-Square tests, with a significance level set at 5%. RESULTS: Group 1 (Z350 XT, without bevel, incremental technique) presented highest rate of microleakage and marginal gap in most of the restorations, with statistically significant differences. Groups 4 and 6 (P90, beveled, builk and P90, beveled and incremental technique) had lower rates of microleakage and absence of marginal gaps in most of the restorations. CONCLUSION: It’s concluded that the silorane showed lower rates of marginal gaps and microleakage, when compared to the conventional methacrylate-based resin. Bevel preparation was effective in reducing microleakage and marginal gaps for both resins used. Incremental technique was not necessary when associated with low shrinkage composite resin.

Abstract:
AbstractExplanations for beveled blade edges on projectile points have been debated in North America archaeology since the first systematic description oflithic assemblages in the nineteenth century. Debate has centered around two opposing perspectives. One views beveled edges as features of projectile points that cause them to spin during flight. The other views beveling as a product of edge resharpening that is done unifacially to conserve scarce resources. Here we use a fluid-dynamics model to simulate the effect beveling has on projectiles. Expectations derived from this modeling are evaluated using windtunnel experiments. Our findings indicate that beveling produces in-flight rotation that serves as a means of increasing accuracy in relatively low-velocity flight paths.

Full text
Abstract:
This thesis examines the historical writing of the twelfth-century Yorkshire historian Alfred of Beverley, compiler of a Latin chronicle covering the history of Britain from its supposed foundation by Brutus down to the time of Henry I. From the late Middle Ages until the eighteenth century Alfred enjoyed a considerable reputation amongst chroniclers, antiquaries and topographers but by the mid-nineteenth century scholarly opinion had come to consider his work highly derivative, uninformative and of little historical value. The chronicle was printed by Thomas Hearne in 1716, but was never edited in the Rolls Series and the text has remained largely neglected until today. Alfred’s sources in the chronicle have been identified and his use of them examined. The circumstances and date of compilation have been reconsidered and supported by internal evidence from the text, a date of compilation of c.1148 - c.1151 x 1154 is proposed. Alfred’s purpose and intended audience of the work has been considered and evidence for the work’s dissemination and reception from the twelfth to the seventeenth century has been gathered in order to assess the place of the work in medieval historiography. This study finds the Historia to be a text of considerable historical interest and value. It shares common features with historical narratives of the first half of the twelfth century in attempting to provide a comprehensive account of the island’s past, but does so in a more concise, less discursive literary manner. It reveals the application of the methodologies of scholastic exegesis to the writing of history, in its language, textual organization and in the interrogation of authorities that it engages in to determine the veracity of historical data.The text is an important witness for the dissemination of the important twelfth-century source texts it uses. It is the first Latin chronicle to incorporate Geoffrey of Monmouth’s British history into its narrative fabric (Henry of Huntingdon’s c.1139 abbreviation of Geoffrey’s history was inserted as a self-standing ‘Letter to Warinus’). Alfred’s critical reception of the Galfridian material is examined in the thesis. The extensive borrowings from Henry of Huntingdon, Geoffrey of Monmouth, John of Worcester and the Durham Historia Regum, provide important evidence for the dissemination of these texts, which the thesis examines. A finding of the study is that the Historia has been powerfully influenced by Henry of Huntingdon’s Historia Anglorum in its structure and thematic approach. The later reception of Alfred’s Historia by Ranulph Higden in his Universal Chronicle Polychronicon is examined and the impact that this had on Alfred’s later reception in historiography, from William Caxton to William Camden is traced and explored.

Webb, Thomas Andrew. "Power losses in spiral bevel gears." Thesis, University of Nottingham, 2010. http://eprints.nottingham.ac.uk/27950/.

Full text
Abstract:
This dissertation describes a numerical modelling strategy for characterising the windage of a spiral bevel gear rotating within a static shroud. The techniques employed include the use of a parametric solid model, and flow field modelling using computational fluid dynamics (CFD) software. A number of hypothetical physical alterations are made to a control system consisting of a gear and a shroud, based on those found in a Rolls-Royce aero engine. Windage is a parasitic power loss that occurs when a gear does work on air and oil within a gas turbine internal gearbox. It leads to degradation of the oil, which wears turbo-machinery and bearing components, shortening their lives. Windage power losses also impact upon the fuel consumption of an engine, reducing its environmental credentials. The requirement of the oil is to cool and lubricate the meshing location of a pair of gears and for it to then be removed from the vicinity of the gear - preventing its re-ingestion and recirculation. The best solution to these issues of reducing windage and managing the oil is to shroud the gear effectively. Additional cooling of oil can mitigate the damage of too much heat generation, but this adds weight and expense to an engine. A parametric model of a shrouded spiral bevel gear is created, which allows for changes to be made to single or multiple dimensions of the gear and shroud. A control volume CFD approach is used, with a single tooth of a gear modelled to reduce computational time. Four gear size variables are tested: inner diameter, outer diameter, cone angle and module (number of teeth). Findings for air-only show that windage can be reduced by: increasing the cone angle; increasing the number of teeth; or decreasing the outer diameter. The effect of changing the inner diameter on windage was found to be complex due to the interaction of gear and shroud upon the system results, but far less significant than the outer diameter, as windage was seen to scale by this variable to the power of 4.3. Changes to the design of the shroud are made, with a comparison of five inlet and five outlet designs. It is found that a sudden restriction at the inlet to the shroud is the most effective way of reducing single phase windage, with additional shroud features that make the flow path more tortuous also helping. The outlet of the shroud is shown to increase windage as it is opened up and permitted to be less restrictive. A series of investigations using a Lagrangian discrete particle model (DPM) to simulate the presence of oil droplets within the system are also presented. It is shown that the destination of oil within the domain is predominantly dictated by the source location of the oil, with little sensitivity to initial velocity or size. Film modelling on the surface of the shroud, using the DPM-based film model, allows the motion of a thin layer of oil to be studied. In conjunction with the five shroud outlet designs, it is shown that a less restrictive, more open shroud outlet design will help prevent re-ingestion of oil that is present within the shrouded area of the gear.

Abstract:
Spiral bevel gears are used widely in the transmission systems of several mechanical applications. The design of spiral bevel gears is very complicated. This is due to the complexity of the gear tooth geometry. This research concentrates on a special type of spiral bevel gears, the Palloid spiral bevel gears. The design methodology is based on the concepts of the machine kinematics. This delivers a numerical model of the spiral bevel gear tooth surfaces. The concept of a three dimensional vector analysis is applied. In addition, the condition of the tangential contact between the meshing surfaces of the cutting tool and gear blank is utilised. This is performed using the mathematical modelling software package MATLAB. The data points of the gear tooth surfaces obtained from MATLAB are defined as the nodes of the finite element mesh avoiding using a CAD package. In order to achieve high accuracy of gear geometry CAD software has to be avoided as the loss of accuracy is a problem combined with using CAD software. In addition, Hertzian contact problem for spiral bevel gears is studied using traditional Hertzian contact theory. Further more, finite element model is also investigated to compare the stress to that achieved from Hertzian analysis. Finite element analysis is applied in order to determine the response of the structure and bending stresses. Finite element analysis code ABAQUS/Standard is employed.

Abstract:
This work is concerned with the comparative study of three minster churches, those of Beverley, Ripon and Southwell, in the period 1066-c1300. It will seek to establish the course of their institutional development in the period, the role they played within the Archdiocese of York, and the effects of change in this period on their institutional identities both individually and collectively. As a study of non-cathedral institutions after the Conquest, it will also necessarily touch upon the relationship between central and local power, the dynamics of institutional change, and the mechanisms employed for the extension of archiepiscopal authority.

Abstract:
Beveling or contouring is an important step in the processing of quartz crystal wafers used in resonators. This paper presents a combined analytical and empirical approach for contouring process modeling. Based on the bevel profile measurement the material removal mechanism is analyzed and new characteristics describing the beveling process are introduced. A process model is developed to determine the process parameters of beveling. Compared to the traditional trial-and-error approach, this approach provides a powerful tool for developing beveling methods for new crystal wafer design and beveling process optimization.

Full text
Abstract:
Back-beveled transition welds for joining unequal wall thickness are often used in gas and oil transmission pipelines, as recommended in the pipeline codes and standards, such as CSA Z662, ASME B31.8, and ASME 31.4. However, one North American pipeline operator has successively utilized a counterbore-tapered design for transition of unequal wall thicknesses for over 30 years. The design philosophy of the counterbore-tapered joint is to reduce the stress concentrations in the heat affected zone, facilitate the welding of unequal wall thickness and NDT while achieving better quality, reliability, and productivity. By conducting a comparative finite element analysis of the two joint designs, the present study evaluated the pressure containment capacities, the stress concentration factors, the stress intensity factors, and the limit loads of plastic collapses for both the counterbore-tapered and the back-beveled designs. The effect of a key design parameter, the counterbore length, on the integrity of the counterbore design was also examined. The results of the comparative analysis showed that compared to the back-beveled joint, when the pipe materials of unequal wall thickness have the same strength, the counterbore-tapered joint has the same pressure containment capacity as the back-beveled joint. The back-bevel design offers lower stress concentration factor, lower stress intensity factor, and higher limit load of plastic collapse than the back-beveled design.

Abstract:
Fabrication of biomimetic cell microenvironment closely resembling the native tissues is critical for regenerative medicine. It remains challenging to create a 3D fibrous microstructure of extracellular matrix on a clinical-relevant scale. In this paper we presented a novel divergence electrospinning strategy for 3D nanofiber structure fabrication. The electrospinning induced by a double-bevel collector was able to quickly generate a multi-layer scaffold, comprised of uniaxially aligned nanofibers, at centimeter scales in all dimensions. The results showed that the internal nanofiber distribution was largely determined by the inclination angle of the axisymmetric bevels of the collector. A larger inclination angle alleviated the polarization of the fiber distribution due to a lower electric force gradient between the spinneret and the bevel surfaces. This technique can be applied in engineering of musculoskeletal soft tissues in which fibrous cytoskeletal organization is critical.

Abstract:
The needle with lancet point (NLP), having three planes at the tip to generate a sharp lancet point, is the most common needle tip geometry. This research presents two five-plane lancet needle designs, the five-plane lancet needle with two back bevels (FLN-B) and five-plane lancet needle with two front bevels (FLN-F), to study the effect of two additional bevel planes on the reduction of soft tissue insertion force over that of the NLP. The mathematical models for inclination and rake angles along the cutting edges, and the grinding procedure and setup parameters for FLN-B and FLN-F are developed. Prototype needles are fabricated and the needle insert test was conducted on PVC phantom tissue which mimics the soft tissue. Compared to NLP, FLN-B and FLN-F have higher inclination and rake angles and can reduce the insertion forces by 9.1% and 8.3%, respectively.

Abstract:
Forge welding is an efficient welding method for tubular joints applicable in oil and gas industries due to its simplicity in carrying out the welding, absence of molten metal and filler metals, small heat-affected zone and high process flexibility. Prior to forging, the ends (bevels) of the joining tubes can be heated by torch or electromagnetic (EM) techniques, such as induction or high frequency resistance heating. The hot bevels are subsequently pressed together to establish the weld. The entire welding process can be completed within seconds and consistently produces superior quality joints of very high strength and adequate ductility. Industrial forge welding of tubes in the field is relatively expensive compared to laboratory testing. Moreover, at the initial stages of a new project sufficient quantities of pipe material may not be available for weldability testing. For these and several other reasons we have developed a highly efficient single station, solid state welding machine that carefully replicates the thermomechanical conditions of full-scale Shielded Active Gas Forge Welding Machines (SAG-FWM) for pipeline and casing applications. This representative laboratory machine can be used to weld tubular goods, perform material characterization and/or simulate welding and heat treatment procedures. The bevel shapes at mating ends of the tubes are optimized by ABAQUS® simulations to fine tune temperature distribution. The main aim of this paper is to establish a welding procedure for welding the tubular joints by the representative laboratory machine. The quality of the welded tubular joint was analyzed by macro/micro analyses, as well as hardness and bend tests. The challenges in optimizing the bevel shape and process parameters to weld high quality tubular joints are thoroughly discussed. Finally a welding procedure specification was established to weld the tubular joints in the representative laboratory machine.

Abstract:
A study was undertaken to develop AWJ processes and tools for trimming carbon fiber composite stringers used in several structural air frame components. The cutting strategy was to trim the stringers flanges from the inside out to allow beveling and to minimize cutting risks. Specially designed small size side fire cutting heads were developed to meet this requirement, and they were first used to cut flat composite material samples with thicknesses up to 1 inch. These cutting tests focused on identifying the cutting speeds for producing high quality surfaces without any frayed edges or delamination and meet the Boeing BAC 5578 specifications. For example, tests were performed to determine the effects of pressure, abrasive flow rate, orifice size, and cutting speed on the taper and surface finish of the produced surface walls. It was shown that cutting stringer material with AWJ is highly feasible both qualitatively and quantitatively. An example cutting rate of 18 inch/min was determined to cut 0.65-inch thick composite to produce better than 400 micro inch surface finish with less than 1 degree taper. Trimming tests were then performed for both 90 and 45 degrees to produce straight and beveled surfaces using sample stringers. This new AWJ process is now being used for production at aircraft subcontractor facilities for the Boeing 787.
