Abstract:
The differences of temporomandibular joint (TMJ) morphologic parameters by using two-dimensional (2D) and three-dimensional (3D) measuring methods were compared. Ten asymptomatic subjects (26.75 ± 4.89 years) were randomly recruited. The 3D models of the maxilla, mandible, and teeth were reconstructed according to cone-beam computed tomography (CBCT) image data. The morphologic parameters of TMJs were measured by the 2D CBCT measuring method (group A) and the 3D reconstruction model measuring method (group B), respectively. The morphologic parameters in each group were assessed by paired samplest-test, and the statistical significance was achieved whenp<0.05. The horizontal condylar angle (HCA), sagittal ramus angle (SRA), medial joint space (MJS), lateral joint space (LJS), superior joint space (SJS), and anterior joint space (AJS) in group A were significantly smaller than those in group B (p<0.05). The HCA on the left side was significantly smaller than that on the right side in group A (p<0.05). However, all the morphologic parameters in group B were not significantly different between left and right sides. In conclusion, there were significant differences for the morphologic parameters of TMJ measured on 2D CBCT and 3D models. 3D measuring method should be used for the detection of TMJ morphology in clinical practice.

Abstract:
Background: In surgical correction of adult spinal deformity (ASD), pelvic incidence (PI)-lumbar lordosis (LL) plays a key role to restore normal sagittal alignment. Recently, it has been found that postoperative lordosis morphology act as an important factor in preventing mechanical complications. However, there have been no studies on the effect of postoperative lordosis morphology on the restoration of sagittal alignment. The primary objective of this study was to evaluate the effect of postoperative lordosis morphology on achievement of optimal sagittal alignment. The secondary objective was to find out which radiographic or morphologic parameter affects sagittal alignment in surgical correction of ASD. Methods: 228 consecutive patients with lumbar degenerative kyphosis who underwent deformity correction and long-segment fixation from T10 to S1 with sacropelvic fixation and follow-up over 2 years were enrolled. Patients were divided according to whether optimal alignment was achieved (balanced group) or not (non-balanced group) at last follow-up. We analyzed the differences of postoperative radiographic parameters and morphologic parameters between two groups. Correlation analysis and stepwise multiple linear regression analysis was performed to predict the effect of PI-LL and morphologic parameters on the sagittal vertical axis (SVA). Results: Of 228 patients, 195 (85.5%) achieved optimal alignment at last follow-up. Two groups significantly differed in postoperative and last follow-up LL (p < 0.001 and p = 0.028, respectively) and postoperative and last follow-up PI-LL (p < 0.001 and p = 0.001, respectively). Morphologic parameters did not significantly differ between the two groups except lower lordosis arc angle (=postoperative sacral slope). In correlation analysis and stepwise multiple linear regression analysis, postoperative PI-LL was the only parameter which had significant association with last follow-up SVA (R2 = 0.134, p < 0.001). Morphologic parameters did not have any association with last follow-up SVA. Conclusions: When planning spine reconstruction surgery, although considering postoperative lordosis morphology is necessary, it is still very important considering proportional lordosis correction based on individual spinopelvic alignment (PI-LL) to achieve optimal sagittal alignment.

Abstract:
Morphologic variability from 25 populations of Acer campestre L. in Bosnia and Herzegovina was analyzed. Morphometric structure of variability and between-population variability was performed based on 10 fruit-parameter characteristics and 19 leaf-parameter characteristics using multivariate statistical analysis. Results confirmed the separation of three submediterranean populations as a group in relation to other tested populations, from which the Banja Luka population is different. Measured leaf parameters were confirmed as a predominant carrier of the morphologic separation between populations. In other Acer species populations within A. monspessulanum and A. intermedium species are separated mainly by fruit and much less by leaf parameters. The southernmost submediterranean populations from Trebinje, Ljubuški, and Mostar regions have smaller leaf areas, which consequently places them within the same morphologic group; their variability is in tight connection with eco-geo-graphical factors, where the ecological distance is a much better predictor of morphological variability compared to geographical distance. The air temperature had the biggest influence on morphological variability regarding the highest in-between correlation. Achieved results may serve for the continuation of the research in other areas of Acer campestre to determine the interactive effect of ecological, geographical, climatic, and migrational factors on their morphologic population plasticity.

Abstract:
We study the morphologic interaction between graphene and Si nanowires on a SiO2substrate, using molecular mechanics simulations. Two cases are considered: (1) a graphene nanoribbon intercalated by a single Si nanowire on a SiO2substrate and (2) a blanket graphene flake intercalated by an array of Si nanowires evenly patterned in parallel on a SiO2substrate. Various graphene morphologies emerge from the simulation results of these two cases, which are shown to depend on both geometric parameters (e.g., graphene nanoribbon width, nanowire diameter, and nanowire spacing) and material properties (e.g., graphene-nanowire and graphene-substrate bonding strength). While the quantitative results at the atomistic resolution in this study can be further used to determine the change of electronic properties of graphene under morphologic regulation, the qualitative understandings from this study can be extended to help exploring graphene morphology in other material systems.

Abstract:
Abstract Rivers constitute an important focus of attention in surface water studies because of their dynamic nature. Therefore, natural rivers develop a wide range of channel forms whose characteristics vary as a function of the position within the fluvial systems. This study examined the river channel morphologic parameters along the alluvial section of River Ogun in South western Nigeria. Data on the channel morphologic variables were collected through field measurement of the bankfull cross sectional characteristics of the river from where the longitudinal characteristics were defined. 48 cross sections were randomly established at bankfull stage along the river channel stretch of 90 km. Bankfull depth and width at each of the cross sections were determined using sonar (electronic sounding machine) that was mounted to a boat. Velocity was measured with the aid of a current meter, while other morphological parameters were estimated from the field data. Analysis of variance revealed that downstream morphological characteristics of the river varies distinctively at each cross section with bedslope as the most significantly varied among all other morphologic parameters (F=91.18; P=0.00). Pearson product moment correlation technique revealed that bankfull width had a correlation of 0.8 and 0.9 with wetted perimeter and cross sectional area respectively while bankfull depth (maximum) had correlations of 0.9, 0.8 and 0.78 with hydraulic radius, wetted perimeter and cross sectional area respectively. The research also revealed that gradient affects the discharge with a positive correlation of 0.9. The study ascertains the extent of variability in the morphologic characteristic of River Ogun which provides scientific basis for river maintenance and management.

Abstract:
During the last century, the importance of membranes has increased drastically in our society; following this trend, their use in everyday life and in the industrial sector has dramatically rised. Consequently, membranes have been object of study in order to develop new material with new characteristics. This work aims at improving a current GVS portfolio-product, by developing a new filter based on alternative material and to substitute a competitor 3 membrane, whose production will be stopped due to the PerFluoroOctanoic Acid content, in a medical device that has to retain human urine. Firstly, the new polymer was studied, in order to understand how it affects membrane properties; once the basic information were obtained, we moved to analyze the influence of all the parameters in the solution preparation and in the casting process. Additionally, we have analyzed and selected the most appropriate membrane support and casting knife, to produce the most reliable membrane. Once we checked all the parameter, a first industrial trial was done based on the knowledge previously obtained; later, the trial has been analyzed to verify the stability of the product and to confirm the success of the industrial scale-up. The industrial trial has been compared with competitors’ membrane after urine test were carried out; the industrial trial showed superior results compared to the other membrane. Later we analyzed the impact of a standard laboratory testing protein on membranes, to observe if they were the main responsible for the pore occlusion after urine contact. Competitor 3 retains the same amount of protein of other membrane, for this reason, the hypothesis previously made was rejected.

Abstract:
Muscle morphological parameters such as fascicle length (FL), pennationangle (PA) and physiologic cross-sectional area (PCSA) can provide an insightinto the reasons of the deteriorated muscle functions caused by pathologies.This study investigates the 3D structure of the lower leg muscles using 3Dfreehand ultrasound (3DfUS). This imaging modality uses a motion capturesystem to track the position of the US probe during acquisition and thusreconstruct the structure of the tissues in 3D. In this study, two subjects werescanned on the medial gastrocnemius (MG) and tibialis anterior (TA) musclesin the lower leg using 3DfUS system. The FL and PA of the muscles werecalculated and compared with the values previously measured using diffusiontensor imaging (DTI). The results using 3DfUS were averagely 19.2% largerin FL and 2.9%larger in PA. In conclusion, 3DfUS can successfully determinemuscle morphological parameters within a physiologically acceptable range.But the differences in FL observed between the two imaging modalities werequite big, which probably was due to the differences in sample size and area.The values can also differ greatly within the 3DfUS measurements as a resultof different manipulations during data processing, and the 3DfUS protocolneeds to be further improved in future studies.

Abstract:
Urban morphology in combination with soundscape planning and design are important parameters towards the development of sustainable cities. Towards this direction this study primarily investigates the effect of urban morphology and green-space related parameters on traffic noise in different analysis levels. Secondly, it complements this first objective approach with a subjective one, investigating peoples’ perceptual attributes using auditory and visual stimuli. Both approaches aim at merging the gap between acoustics and planning on the grounds of the new holistic approach of urban sound planning. At first, a triple level analysis was conducted including case study cities across Europe with a view to understand to what extent greener cities can also be quieter. The analysis was conducted using GIS tools and noise data from European databases combined with land cover parameters. Results were scale-dependent with lower noise levels to be achieved in cities with a higher extent of porosity and green space coverage. A further cluster analysis combined with land cover data revealed that lower noise levels were detected in the cluster with the highest green space coverage. At last, a new index of ranking cities from the noisiest to the quietest was proposed. Using the findings concerning green spaces and traffic noise from the previous study, a second analysis was conducted focused on eight UK cities. The green space variables were adjusted to incorporate also parameters related to spatial pattern and smaller ontologies, such as vegetated backyards or front yards. Parameters related to urban morphology, such as buildings and roads were also investigated. The analysis was conducted in a macro, meso and micro scale using regression models and GIS tools. Cities were divided in two types of settlement forms (linear, radial) and results showed that the latter were associated with a higher green space ratio. Green space and morphological parameters managed to predict the Lden levels in two cities with an explained variance up to 85%. Results suggested that urban green space variables combined with other features of urban morphology conduct a significant role in traffic noise mitigation and can be used as a priori tool in urban sound planning. The third part of the study focused particularly on the effects of vegetation and traffic-related parameters on the sound environment of urban parks. The sound environment was evaluated using both simulated traffic data and in situ measurements from mobile devices inside the parks. Results showed that simulated noise distribution in the park scale varied between 43 and 78 dB(A) with a maximum range of 9 dB(A) per park and higher noise variability for LA10. Two groups of parks were identified according to the distance from the international ring road. For measurement data, LA90 and LA10 were higher outside the parks with differences up to 6 dB(A) for LA90 and up to 14.3 dB(A) for LA10. Additional correlations were also detected between noise levels and morphological attributes, while slightly higher noise levels were detected in areas covered with grass compared with tree areas. The previous objective findings were combined with a perceptual study on the transition from prediction to soundscape and design implementation. In this study the relationship between land use and sound sources was explored. The stimulus material was based on binaural recordings and 360°-videos. Participants were required to assess the dominance of sound sources and the appropriateness of land use and socio-recreational activities. Results showed that the activity-based environment can be explained by two main Components. The green space coverage and the proximity to roads were the most significant parameters in the prediction of these two components. In the final stage, a multivariate analysis (MANOVA) was used in order to identify significant variations for the land use activity variables in the three urban activity profiles. The whole process emphasized on the importance of linking urban planning and design with soundscape from the land use activity viewpoint. In the final stage, two of the previous UK case study cities were selected in order to develop a mapping model to aid soundscape planning with parallel implementation and assessment of its effectiveness. Ordinary Kriging interpolation was used in both cases to simulate the predictive values in unknown locations. In Sheffield, the soundscape model was based on the prediction and profiling of sound sources, while in Brighton in the prediction and profiling of perceptual attributes. The cross-validation process in both cases presented small errors with slightly underestimated prediction values. The outcomes from both case studies can be applied in environmental noise management and soundscape planning in different urban scales.

Full text
Abstract:
Laser micromachining is one of the principal fields where the laser capability to change the material morphology is frequently applied and silicon is still the element most used in the semiconductor and photovoltaic industries despite the recent studies on new materials. Although various models reported in the literature describe the laser material interaction, the relation between the ablated crater morphology and the laser beam parameters remains unclear or does not give methods and equations that can be applied on the engineering environment. The aim of this thesis is to reduce the knowledge gap of the understanding of three laser parameters (pulse duration, energy beam shape, and polarisation) influence on the ablated crater morphology by providing functions and relations that can be applied in the engineering environment. First, a systematic study on laser pulse duration based on two different functions (i.e. thermal-based and non-thermal based) is carried out, then the impact of the thermal effect on crater morphology of two non-standard energy beam distributions (i.e. round flat-top and square-top) is evaluated, and finally the laser polarisation effects in the non-linear laser ablation regime are explored, providing the engineering environment of new functions and relations between laser beam parameters and crater morphology.

Abstract:
The present research was envisioned as a project defined by multiple studies that are strictly correlated each other. The report of the birth, development and practical application to the diagnostic and surgery fields of a novel 3D approach for the computation of femoral measurements was the first aim. Moreover, in the authors’ purpose the description of the translational value of the proposed procedure enhanced with its plausible utility to the daily practice of orthopaedic surgeons, represented another focal point. In this sense, the research started from the validation of the 3D assessment of femoral morphometric parameters. Veterinary literature reports tons of papers describing several methodologies for obtaining femoral measurements through different diagnostic techniques. Furthermore, bibliography presents lot of angles values that are currently adopted and considered as reference parameters for most of the corrective osteotomies. Additionally, in the recent past an increased emphasis on 3D approach grown but little if any attention was devoted to 3D measurements. This trend represented in the authors’ mind the gap with the current knowledge and, thus, an area to be deeply investigated. Indeed, to the best of author knowledge, there were no papers documenting the assessment of 3D femoral axes and angles in veterinary medicine, with no 3D protocol described. In addition, currently available canine femoral measurements related to frontal, sagittal and transverse deformities have only been computed in bi-planar projections, whether acquired from 2D or 3D imaging models. Therefore, starting from the accepted human methods and from the features definition in veterinary literature, we proposed a new approach. The first study was designed to define a 3D methodology, introducing a consistent and quantitative method for the assessment of femoral morphometric parameters in 3D geometrical models. To validate the proposed approach, accurate geometric data were necessary and, therefore, we opted for meshes obtained by a 3D scanner, instead of CT images. Once the validation of the was stated, our focus was directed towards the evaluation of the precision of the proposed 3D protocol. The validation of a novel diagnostic test requires verification of the repeatability, defined as the strength of agreement between repeated measurements of the same samples performed from one examiner, and the reproducibility as well, that express the same variance but between a group of observers. Furthermore, the accuracy of the measurements indicates how close the measurements took with the investigated technique to a true value (gold standard). Therefore, a second project was designed to test the precision of three diagnostic techniques, two largely diffuse (Rx and TC) one recently introduced in veterinary (3D), for the measurement of femoral angles. The second purpose of this study was the investigation of the potential application of the algorithm implemented in a computer-aided-design (CAD) software, using CT data. Considering that for the first study we worked with 3D scanner data, the main aim at this point of the research was represented by the enhancement of the presented 3D protocol for diagnostic purposes. In the author opinion, changing the source of data was necessary because of the availability of CT and MRI equipment in veterinary practice. Finally, the last goal of this project was the translation of the application of 3D computation to the surgical field. The current research contemplates the fact that the augmented interest on 3D computation is not only relevant for diagnostic reasons, but also for surgery. Thus, the correlation between the diagnostic utility of the 3D approach and its plausible practice for surgery purposes was the object of the final study. The starting point was suggested by veterinary literature that reports in few papers the development and application of surgical devices used to perform assisted-correction of bone deformities. These surgical tools are designed through 3D geometrical models and act both as precise intraoperative localizers of osteotomy corrective landmarks and surgical saw guides. Three-dimensional assessment of a bone conformation may improve the understanding and evaluation of bone deformities and occurring joints malalignment. In this sense, the localization of the CORA as well as the accuracy of the orientation of the osteotomy-cutting plane may be significantly upgraded through a 3D approach.<br>La tesi di dottorato presentata è stata concepita nell’ambito di un più ampio progetto che comprende molteplici studi tra loro intrinsecamente correlati. L’obiettivo principale del lavoro consiste nella descrizione delle basi teoriche, sviluppo nonchè applicazione pratica nel campo della diagnostica per immagine e chirurgia di un nuovo protocollo 3D utilizzato per la misurazione di angoli nel femore del cane. Lo scopo successivo è stato quello di descrivere il valore traslazionale della procedura analitica qui presentata. Il primo passo dell’intera ricerca è rappresentato dalla validazione della metodologia. Un nuovo algoritmo sviluppato consente, per mezzo di un CAD software di comune utilizzo (Rhinoceros), di eseguire la computazione di angoli in 3D. Il secondo step ha previsto la verifica della ripetibilità e della riproducibilità di tale metodica che è stata comparata con quelle più comuni effettuate con radiografia e Tac. Infine, con l’ultimo studio abbiamo traslato le basi teoriche in applicazione chirurgica andando a creare, per mezzo dell’algoritmo elaborato, delle dime chirurgiche. Questi strumenti intra-operatori sono molto utili durante la chirurgia per le osteotomie correttive in quanto si accoppiano perfettamente nel punto di deformità e consentono di guidare l’osteotomia dell’osso.

Abstract:
The volume deals with the multifaceted nature of morphological complexity understood as a composite rather than unitary phenomenon as it shows an amazing degree of crosslinguistic variation. It features an Introduction by the editors that critically discusses some of the foundational assumptions informing contemporary views on morphological complexity, eleven chapters authored by an excellent set of contributors, and a concluding chapter by Östen Dahl that reviews various approaches to morphological complexity addressed in the preceding contributions and focuses on the minimum description length approach. The central eleven chapters approach morphological complexity from different perspectives, including the language-particular, the crosslinguistic, and the acquisitional one, and offer insights into issues such as the quantification of morphological complexity, its syntagmatic vs. paradigmatic aspects, diachronic developments including the emergence and acquisition of complexity, and the relations between morphological complexity and socioecological parameters of language. The empirical evidence includes data from both better-known languages such as Russian, and lesser-known and underdescribed languages from Africa, Australia, and the Americas, as well as experimental data drawn from iterated artificial language learning.

Full text
Abstract:
Morphological structures interact dynamically with lexical processing and storage, with the parameters of morphological typology being partly dependent on cognitive pathways for processing, storage and generalization of word structure, and vice versa. Bringing together a team of well-known scholars, this book examines the relationship between linguistic cognition and the morphological diversity found in the world's languages. It includes research from across linguistic and cognitive science sub-disciplines that looks at the nature of typological diversity and its relationship to cognition, touching on concepts such as complexity, interconnectedness within systems, and emergent organization. Chapters employ experimental, computational, corpus-based and theoretical methods to examine specific morphological phenomena, and an overview chapter provides a synthesis of major research trends, contextualizing work from different methodological and philosophical perspectives. Offering a novel perspective on how cognition contributes to our understanding of word structure, it is essential reading for psycholinguists, theoreticians, typologists, computational modelers and cognitive scientists.

Full text
Abstract:
Current understanding of syntactic variation and change relies on the notion of parameters of varying magnitude (micro- and macroparameters). This chapter focuses on the flipside of parameter change, namely the retention and survival of synthetic morphological structure in a context of widespread analyticization. The global effects of synthetic-to-analytic drift are examined in two diachronic scenarios: one in which the process has almost, though not entirely been completed (Coptic Egyptian), and another one in which the process is still under way (Brazilian Portuguese). Coptic has gone very far in abandoning its former synthetic features and thus exhibits a high degree of analyticity. In Brazilian Portuguese, the analyticization process is an advanced state, with synthetically inflected tenses exhibiting a decreasing productivity and gradually being replaced by the corresponding auxiliary verb constructions in the spoken language. The restriction on verb movement is a side effect of ongoing analyticization that affects language’s word order.

Abstract:
The capacity of echocardiography to non-invasively identify the major causes of circulatory failure has made it increasingly popular in the intensive care unit (ICU) setting. Assessing cardiac performance in shocked patients is a key point in therapeutic support decision-making. Analysing left and right ventricular function and morphology should be mandatory in the training curriculum of ICU physicians. Haemodynamic evaluation relies on several parameters examining left ventricular systolic and diastolic function, left ventricular filling pressure, fluid responsiveness, and right ventricular function. To correctly interpret the echocardiographic findings and adapt patient management appropriately, physicians must be aware of the limits of these parameters.

Abstract:
AbstractThe theranostic concept to use diagnostic and therapeutic nuclides to image and treat cancer was established many years ago for thyroid disease. With the success of [177Lu]-labeled therapeutic agents targeting neuroendocrine tumors or prostate cancer, the interest for this concept has been significantly rising. The possibility to localize and quantify a therapeutic target within the patient opens up novel possibilities, but also challenges for patient selection, dosimetry, and response assessment. Especially for response assessment we however, still rely on the morphologic changes. With the increasing use of immunotherapy and other biological approaches, image interpretation needs a profound understanding of the therapeutic mechanism and impact on imaging parameters for accurate assessment of tumor response and guidance for appropriate therapy selection.

Abstract:
Abstract The built form of cities is a synthesis of various aspects including climate, culture, and economics, presenting a challenge in the analysis of urban morphology. The ‘plot’ has been used as the basic unit of analysis which aggregates formal and relational attributes essential to urban morphological analysis. The recently introduced Morphological Tessellation (MT) method automatically generates morphological units from building profiles, using a Voronoi Tessellation (VT). However, the generation of higher quality tessellation results relies on resource-intensive computing and careful configuration of proper parameter presets. To address this issue, this paper introduces an adaptive tessellation workflow based on the improvement of a specific tessellation pattern near closely aligned buildings. This paper then discusses a method to incorporate linear guides to control the tessellation outcome, allowing for increased control over the shape of the outcome of MT. The workflow is realised in a Grasshopper Assembly developed for Rhinoceros 3D in C#. This workflow proves to generate geometrically desirable outcomes with substantially reduced computational workload.

Full text
Abstract:
Abstract In 1996 Pots has written a two-dimensional (2-D) stochastic algorithm to simulate the morphology of localized attack. The rule based algorithm operates on the assumption that the morphology of corrosion attack depends on the balance of two processes: corrosion (leading to metal loss) and precipitation (leading to metal protection). The rules of the original algorithm were modified to enable simulation of a broader variety of localized corrosion morphologies found in practice. The algorithm, which uses scaling tendency as the only input parameter, was connected with the mechanistic model of CO2 corrosion so that the morphology of localized attack can be predicted as a function of primitive parameters such as temperature, pH, partial pressure of CO2, velocity, etc. Based on the results of the simulations, it was postulated that partially protective films are sufficient to trigger localized attack, which is in agreement with the experimental observations.

Abstract:
Abstract The acceptance of materials for long-term, safety-critical power generation applications requires multiple testing stages and data generation. Initial screening involves short-term exposures under simplified, constant atmospheres and temperatures, which can eliminate unsuitable materials but fail to distinguish between those with broadly acceptable properties. Subsequent pilot plant testing, costing over £100K for month-long exposures, is typically required. An intermediate laboratory testing step that better replicates in-service conditions would offer a cost-effective approach to material selection and lifetime prediction. For steam oxidation degradation, key experimental parameters—such as water chemistry, pressure, steam delivery, and flow rate—must be tailored to produce oxide scale morphologies similar to those observed in actual plant conditions. This study examines the effects of these parameters through steam exposure tests on ferritic (P92), austenitic (Esshete 1250), and superalloy (IN740) materials. Results indicate that oxidation rates vary with dissolved oxygen levels in feed water, increasing for austenitic materials and decreasing for ferritic materials, while also influencing spallation tendencies. Additionally, steam pressure and delivery methods impact oxidation rates and scale morphology. A comparison with service-exposed materials revealed that traditional oxide scale morphologies were not adequately replicated, whereas cyclic oxidation tests provided a closer match to service-grown scales.

Abstract:
Abstract The morphology of γ/γ' microstructures in single crystal superalloys is known to evolve during service conditions according to established materials science principles, potentially offering a novel approach for failure analysis. This study investigated the morphological changes in γ/γ' microstructures of CMSX-4, a single crystal Ni-base superalloy, under various loading conditions. The experimental parameters included tensile and compressive stress levels, loading temperature, loading rate, monotonic versus cyclic loading, and multi-axial stress states. Results demonstrated that the γ/γ' microstructures exhibited highly sensitive responses to these loading conditions. A newly developed quantitative image analysis method was used to characterize these morphological changes, and the findings were compiled into a two-dimensional map to facilitate failure analysis and other engineering applications.

Full text
Abstract:
Given the considerable risk of treating unruptured intracranial aneurysms (IAs), as well as the known severe morbidity of aneurysm rupture, elucidating those aneurysms that require prophylactic treatment can be a quandary. Traditionally, decision-making to treat an unruptured aneurysm was largely based on the Size of the aneurysm, but recent studies have failed to show significant correlation of Size with IA rupture, and a large number of ruptured aneurysms are small in Size.[1] Consequently, shape-based morphologic metrics have been explored in current investigations, and complex shapes have been correlated with rupture.[1] With the advancement of 3D angiography, and computational fluid dynamics (CFD) technology, patient-specific hemodynamics analysis has become feasible. Intra-aneurysmal hemodynamic factors, including wall shear stress (WSS), impingement regions, and oscillatory shear index (OSI), have been proposed as indicators for IA rupture risk.[2, 3] No study has rigorously examined both morphology-based and hemodynamics-based parameters from a uniform cohort to compare their relative importance. Our aim, therefore, was to identify significant morphologic and hemodynamic parameters that correlate with an aneurysm’s rupture status and examine whether hemodynamic parameters can separate ruptured and unruptured aneurysms better than morphologic parameters.

Abstract:
Intracranial aneurysms (IAs) rupture results in severe morbidity and mortality. Therefore indentifying IA rupture risk is highly critical. Although it has been recognized that IA rupture is the result of a complex vascular degeneration process involving multiple mechanobiological factors, such information for each patient is not readily available in clinical setting. Alternatively, morphology and hemodynamic metrics can be derived from routine patient-specific imaging. In previous studies, a number of morphological metrics derived from analysis of reconstructed vascular 3D geometry have shown significance in discriminating ruptured from unruptued IAs, including in particular aneurysm size ratio, defined as IA size divided by the parent vessel diameter. However, these measures rely on 3D image segmentation and measurement, which makes them less practical in current angiographic rooms often equipped with only biplane angiogram capability and even when 3D rotational angiography is available, on-site 3D image segmentation and analyses are still not practical. Our foregoing study examined three parameters measured on 2D angiographs: aneurysm Size Ratio (SR), Aspect Ratio (AR) and Size. We found that SR had the strongest correlation with IA rupture. The current study further evaluates these geometric metrics, measured both from 3D and 2D images, with a larger cohort of saccular intracranial aneurysms.

Full text
Abstract:
Wetland construction in tidally influenced embayments is a strategy for beneficial use of sediment dredged from nearby navigation channels. These projects have the potential to alter basin morphology, tidal hydrodynamics, and shoaling trends. This special report provides a broad review of the literature related to engineering-induced changes in tidal range, salinity, tidal prism, tidal asymmetry, and other known causes of shoaling. Each potential shoaling mechanism is then evaluated in the context of wetland placement to provide a foundation for future beneficial use research. Based on a compilation of worldwide examples, wetland placement may reduce tidal amplitude and enhance ebb current dominance, thus reducing shoaling rates in the channels. However, constructed wetlands could also reduce the embayment’s tidal prism and cause accelerated shoaling relative to the pre-engineered rate. Because constructed wetlands are often created in conjunction with navigation channel dredging, the system’s morphologic response to wetland construction is likely to be superimposed upon its response to channel deepening, and the net effect may vary depending on a variety of system-specific parameters. Planning for future wetland placements should include an evaluation of local hydrodynamic behavior considering these factors to predict site-specific response.

Full text
Abstract:
The Old River Control Complex (ORCC) consists of the Low Sill, Auxiliary, and Overbank structures as features of the Old River Control Structure (ORCS) and the privately owned hydro-electric power plant. Operations of the ORCC manage the hydrologic connectivity between the Mississippi River and the Atchafalaya River/Red River systems. The morphology of the Old, the Mississippi, the Atchafalaya, and the Red Rivers (OMAR) has been influenced by the flow distribution at the ORCC, as well as the accompanying bed sediments. A geomorphic assessment of the OMAR is underway to understand the morphological changes associated with operation of the ORCC. Supporting the geomorphic assessment, a channel geometry analysis herein documents observed adjustments of the affected river channels. Historical hydrographic survey data were used in the Geographic Information System to create river channel geometric models, which inform the analysis. Geometric parameters for cross sections and volume polygons were computed for each survey and evaluated for morphological trends which may be ascribed to the influence of the ORCC. Additionally, the geometric parameters for the Atchafalaya River were used to extend the geometry analyses from the 1951 Mississippi River Commission report on the Atchafalaya River, which was the primary catalyst for the initial development of the ORCS.

Abstract:
Previous research has demonstrated the use of single-channel porcine-derived urinary bladder matrix (UBM) conduits in segmental-loss, peripheral nerve repairs as comparable to criterion-standard nerve autografts. This study aimed to replicate and expand upon this research with additional novel UBM conduits and coupled therapies. Fifty-four Wistar Albino rats were divided into 6 groups, and each underwent a surgical neurectomy to remove a 7-millimeter section of the sciatic nerve. Bridging of this nerve gap and treatment for each group was as follows: i) reverse autograft—the segmented nerve was reversed 180 degrees and used to reconnect the proximal and distal nerve stumps; ii) the nerve gap was bridged via a silicone conduit; iii) a single-channel UBM conduit; iv) a multi-channel UBM conduit; v) a single-channel UBM conduit identical to group 3 coupled with fortnightly transcutaneous electrical nerve stimulation (TENS); vi) or, a multi-channel UBM conduit identical to group 4 coupled with fortnightly TENS. The extent of nerve recovery was assessed by behavioural parameters: foot fault asymmetry scoring measured weekly for six weeks; electrophysiological parameters: compound muscle action potential (CMAP) amplitudes, measured at weeks 0 and 6; and morphological parameters: total fascicle areas, myelinated fiber counts, fiber densities, and fiber sizes measured at week 6. All the above parameters demonstrated recovery of the test groups (3-6) as being either comparable or less than that of reverse autograft, but none were shown to outperform reverse autograft. As such, UBM conduits may yet prove to be an effective treatment to repair relatively short segmental peripheral nerve injuries, but further research is required to demonstrate greater efficacy over nerve autografts.

Full text
Abstract:
In the transformation operations of polymeric materials, there is a complex interplay between transport phenomena and crystallization. In particular, the polymer in the molten state is a viscoelastic fluid with rheological parameters depending on temperature, pressure, crystallinity, and molecular stretch. The molecular stretch is a tensor variable with values determined by the history of the flow, temperature, and pressure fields. During polymer processing operations, several phenomena proceed simultaneously by interacting with each other. The combination and interplay of the models that describe each of the phenomena mentioned above provides the evolution of all the relevant quantities and, therefore, also the overall model that describes the evolution of the solidification that generally proceeds starting from the walls (where the temperature is lower and furthermore the shear is higher). This work presents an overall model of the behavior of an isotactic polypropylene during the injection molding process. The model includes the kinetics of spherulitic and fibrillar crystallization and their dependence on the level of molecular stretch; the modeling is carried out up to the prediction of molecular stretch and morphology distributions along the molded part thickness. The model predictions satisfactorily describe the evolution of temperature and pressure during the process and the fundamental aspects of the morphology distribution inside the part.

Abstract:
S. cerevisiae JCM 7255 from brewing industry was tested to be a possible probiotic candidate in aquaculture together with encapsulation and freeze-drying technique. In vitro viability and morphology analysis of probiotic during storage and during transient with stimulated tilapia gut and bile conditions were evaluated as well as In vivo growth performance efficacy, gut mucosal immune parameters and anti-Streptococcal activity. The In vitro results showed that the viabilities of encapsulated yeasts remained in the high number after storage in room temperature for 14 days, while the viability of free S. cerevisiae could not be detected after 7 days pass. The viability of encapsulated yeast in simulated gastric condition and in tilapia bile was significantly higher than the free non-encapsulated group. The morphology of free S. cerevisiae revealed oval, rough bumpy surface and 2- 4 budding knots with rupture on the surface during incubation in gut and bile conditions. The in vitro anti-streptococcal activity of encapsulated yeast using agar spot test showed inhibitory reaction against 20 from 30 strains of S. agalactiae. The in vivo study showed that supplementation with encapsulated yeast improved the intestinal structure and growth performance in tilapias. A significantly increase number of intraepithelial lymphocytes in proximal intestine were observed while acidophilic granulocytes and mucous cells were not statistically different in any part of the intestine. Lowering the cumulative mortality after oral streptococcal challenge was also observed without statistical significance when compare with control group. The results suggested that encapsulated S. cerevisiae JCM 2755 could be a potential probiotic candidate in tilapia culture.

Abstract:
Vibration compaction is the most effective way of compacting coarse-grained materials. The effects of vibration frequency and amplitude on the compaction density of different backfill materials commonly used by INDOT (No. 4 natural sand, No. 24 stone sand, and No. 5, No. 8, No. 43 aggregates) were studied in this research. The test materials were characterized based on the particle sizes and morphology parameters using digital image analysis technique. Small-scale laboratory compaction tests were carried out with variable frequency and amplitude of vibrations using vibratory hammer and vibratory table. The results show an increase in density with the increase in amplitude and frequency of vibration. However, the increase in density with the increase in amplitude of vibration is more pronounced for the coarse aggregates than for the sands. A comparison of the maximum dry densities of different test materials shows that the dry densities obtained after compaction using the vibratory hammer are greater than those obtained after compaction using the vibratory table when both tools were used at the highest amplitude and frequency of vibration available. Large-scale vibratory roller compaction tests were performed in the field for No. 30 backfill soil to observe the effect of vibration frequency and number of passes on the compaction density. Accelerometer sensors were attached to the roller drum (Caterpillar, model CS56B) to measure the frequency of vibration for the two different vibration settings available to the roller. For this roller and soil tested, the results show that the higher vibration setting is more effective. Direct shear tests and direct interface shear tests were performed to study the impact of particle characteristics of the coarse-grained backfill materials on interface shear resistance. The more angular the particles, the greater the shear resistance measured in the direct shear tests. A unique relationship was found between the normalized surface roughness and the ratio of critical-state interface friction angle between sand-gravel mixture with steel to the internal critical-state friction angle of the sand-gravel mixture.
