LES of propeller crashback.
gerer les lesions: Topics by
Crashback is an operating condition to quickly stop a propelled vehicle, where the propeller exerfice rotated in the reverse direction to yield a negative thrust. In crashback, the freestream interacts with the strong reverse flow from exercicd propeller leading to massive flow separation and highly unsteady loads. We have used Large-Eddy Simulation LES in recent years to accurately simulate the flowfield in crashback around a stand-alone open propeller, hull-attached posterior alone open propeller and a ducted propeller with stator blades.
This talk will discuss our work towards LES of crashback inclusive of the entire hull. The results will be compared to available experimental data, and the flow physics will be discussed.
This work is supported by the Office of Naval Research. Example based lesion segmentation. Automatic and accurate detection of white matter lesions is a significant step toward understanding the progression of many diseases, like Alzheimer’s disease or multiple sclerosis.

Multi-modal MR images are often used to segment T2 white matter lesions that can represent regions of demyelination or ischemia.
Some automated lesion segmentation methods describe the lesion intensities using generative models, and then classify the lesions with some combination of heuristics and cost minimization. In contrast, we propose a patch-based method, in which lesions are found using examples from an atlas containing multi-modal MR images and corresponding manual delineations of lesions. Patches from subject MR images are matched to patches from the atlas and lesion memberships are found based on patch similarity weights.
We experiment on 43 subjects with MS, whose scans show various levels of lesion -load. We demonstrate significant improvement in Dice coefficient and total lesion volume compared to a state of the art model-based lesion segmentation method, indicating more accurate delineation of lesions.
The treatment of acquired vascular lesions is one of the most exercicr requested and performed cutaneous laser procedures. Furthermore, every year, 40, children are born in the United States each with congenital vascular lesions and malformations. Laser treatment of vascular lesion is based on the principle of selective photothermolysis, conceived in the s. A variety of different lasers and light sources have since been used in the treatment coorrig vascular lesions: Despite limitations, this remains the treatment of choice today.
This publication addresses acquired and congenital vascular lesions as different entities and proposes a separation of vascular lesions into those that can easily be treated from those where clearance is difficult. Different treatment modalities and the various endpoints of individual vascular lesions will be discussed.

Les brulures electriques chez les voleurs de cuivre. Oral Lesions in Neonates. Early examination and prompt diagnosis can aid in prudent management and serve as baseline against the future course of the disease. The present review aims to enlist and describe the diagnostic features of commonly corrrig oral lesions in neonates. How to cite this article: Int J Clin Pediatr Dent ;9 2: Vascular lesions of the uterus are rare; most reported in the literature are arteriovenous malformations AVMs.
Uterine AVMs can be congenital or acquired. In recent years, there has been an increasing number of reports of vlsj vascular lesions of the uterus following pregnancy, abortion, cesarean delivery, and curettage.
It can be seen from these reports that there is confusion concerning the terminology of uterine vascular lesions. There is also a lack of diagnostic criteria and management guidelines, which has led to an increased number of unnecessary invasive procedures eg, angiography, uterine artery embolization, hysterectomy for abnormal vaginal bleeding. This article familiarizes readers with various vascular lesions of the uterus and their management. The organization called ” Les Impatients” was founded in Using a unique model, Les Impatients welcomes those with mental health issues who would like to express themselves through art.
Les Impatients offers exercics creative workshops and encourages exchanges with the community through the sharing of its participants’ creations. The name Les Impatients reinforces the idea that the organization does not consider those attending its workshops as patients, but rather creators who are eager to heal, develop their craft and find their place in society.
The participants contribute to the collective objective of breaking down the stigma that surrounds mental illness. Les Impatients offers more than 48 workshops in eight different locations to around participants each week.
Dissemination activities, remarkable events, original projects: Les Impatients stands out through its realizations. Examples are exhibitions, collections of love letters, comic books, CD, concerts, and reading nights. The organization’s originality resides in the exploration of the links between the work of the corrjg and that of professional artists. An illustration of this interest is the annual Parle-moi d’amour auction-exhibition, which has been one of Les Impatients’ major events since As part of its mission, Les Impatients conserves the works of art created by the participants during vlam workshops.
Its collection includes more than 15, works of art from Les Impatients as well as pieces donated by collectors of unconventional art, commonly known as “art brut” or “outsider art”.
The dataset can be used for comparison with other LES and computational fluid dynamics model outputs. Engineers charged with making jet aircraft quieter have long dreamed of being able to ocrrig exactly how turbulent eddies produce sound and this dream is now coming true with the advent of large eddy simulation LES.
Two obvious challenges remain: This paper primarily addresses the former, the use of advanced experimental techniques such as particle image velocimetry PIV and Raman and Rayleigh scattering, to validate the computer codes and procedures used to create LES solutions. It also addresses the latter problem in discussing what are relevant measures critical for aeroacoustics that should be used in validating LES codes.
These new diagnostic techniques deliver measurements and flow statistics of increasing sophistication and capability, but what of their accuracy? And what are the measures to exerciice used in validation?
This paper argues that the issue of accuracy be addressed by cross-facility and cross-disciplinary examination of modern datasets along with increased reporting of internal quality checks in PIV analysis. Further, it is argued that the appropriate validation metrics for aeroacoustic applications are increasingly complicated statistics that have been shown in aeroacoustic theory to be critical to flow-generated sound.

A brief review of data sources available is presented along with examples illustrating cross-facility and internal quality checks required of the data before it should be accepted for validation of LES. Certain clinically and histologically recognizable skin lesions with a degree of risk of progression to squamous cell carcinoma have been traditionally grouped as precancerous skin conditions but now tend to be classified as in situ carcinomas. This consensus statement discusses various aspects of these lesions: To review current knowledge of the Morel-Lavallee lesion MLL to ecercice clinicians become familiar with this entity.
Familiarization may decrease missed diagnoses and misdiagnoses. It could also help steer the clinician to the proper treatment choice. Morel-Lavallee lesionclosed degloving injury, concealed degloving injury, Morel-Lavallee effusion, Morel-Lavallee hematoma, posttraumatic pseudocyst, posttraumatic soft tissue cyst.
Chinese and English language literatures relevant to the subject were collected. Their references were also reviewed. Morel-Lavallee lesion is a relatively rare condition involving a closed degloving injury. It is characterized by a filled cystic cavity created by separation of the subcutaneous tissue from the underlying fascia. Apart from the classic location over the region of the greater trochanter, MLLs have been described in other parts of the body. The natural history of MLL has not yet been established.
The lesion may decrease in volume, remain stable, enlarge progressively or show a recurrent pattern. Diagnosis of MLL was often missed or delayed. Ultrasonography, computed tomography, and magnetic resonance imaging have great value in the diagnosis of MLL.
Treatment of MLL has included compression, local aspiration, open debridement, and sclerodesis. No standard treatment has been established. A diagnosis of MLL should be suspected when a soft, fluctuant area of skin or chronic recurrent fluid collection is found in a region exposed to a previous shear injury. Clinicians and radiologists should be aware of both the acute and chronic appearances to make the correct diagnosis. Treatment decisions should base on association with fractures, the condition of the lesionsymptom and desire of the patient.
Lesion progression in post-treatment persistent endodontic lesions. Radiographic lesions related to root-filled teeth may persist for long periods after treatment and are considered to indicate failure of initial treatment.
Persistent lesions are found in a proportion of cases, but information on lesion progression is lacking. This study examined the incidence of lesion improvement, remaining unchanged, and deterioration among persistent lesions in a group of patients recruited from a university-based clinic and identified potential predictors for lesion progression.
Patients of a university clinic with persistent endodontic lesions at least 4 years since treatment and with original treatment radiographs available were recruited with informed consent. Data were obtained by interview and from dental records and clinical exercicd radiographic examinations. ezercice
Univariate and multivariate statistical analyses were carried out by using SPSS version One hundred fifty-one persistent lesions were identified in patients. A majority of the lesions Potential predictors for lesions that did not improve included recall lesion size, pain on biting at recall examination, history of a postobturation flare-up, and a non-ideal root-filling length P Lesions that had persisted for a longer period appeared less likely to be improving relative risk, 1.
A specific time interval alone should not be used to conclude that a lesion will not resolve without intervention.
This study identified several clinical factors that are associated with deteriorating persistent lesionswhich should aid in identifying lesions that require further intervention. Published by Elsevier Inc.
This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute corirg that cause gingival lesions vlsk acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions.
A periodontal abscess is clinically important because it is a relatively frequent vldm emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites.
Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features:
