Abstract For men experiencing lower urinary tract symptoms (LUTS) refractory to medical therapy, there have been numerous developments in the treatment options offered for benign prostatic hyperplasia (BPH) in the recent years. Transurethral resection of the prostate (TURP) has remained the reference standard for men with prostates sized 30 cc-80 cc, while open prostatectomy is universally guidelines-recommended in the absence of enucleation, for men with prostates larger than 80 cc-100 cc. While these techniques are effective, they have the potential for bleeding complications requiring transfusions, electrolyte abnormalities such as TURP syndrome, and often require prolonged hospitalization.… More >

Abstract Introduction: There has been growing use of adrenalectomy as a potentially curative treatment option for patients with oligometastatic disease to the adrenal gland. We sought to compare the perioperative outcomes of patients undergoing isolated adrenalectomy in the setting of disseminated cancer using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Furthermore, we examined the impact of performing surgical sub-specialty on outcomes.
Materials and methods: Data from the ACS-NSQIP database was obtained for patients between 2011 and 2016 who underwent adrenalectomy. Patients were stratified by the presence or absence of disseminated cancer. Univariate and… More >

Abstract Introduction: Dystroglycan (DG) is a cell surface receptor for extracellular matrix proteins involved in tissue mechanical stability and matrix organization. Initial work has demonstrated that alpha-DG expression is decreased in many types of adenocarcinoma, including prostate, and potentially associated with the development of metastatic disease. However, the consistency between prostate and lymph node alpha-DG staining has not been previously reported. Additionally, identification of an immunohistochemical marker associated with prostate cancer grade, stage, need for adjuvant or salvage therapy, and mortality would have potential clinical value.
Materials and methods: Node-positive, margin-negative radical prostatectomy specimens from a single institution… More >

Abstract Introduction: Robotic cystectomy with intracorporeal urinary diversion (RCID) is a technically challenging procedure. It is understood that this approach has a learning curve; however, limited studies have characterized this learning curve. The cumulative sum (CUSUM) method plots the learning curve. The aim of this study was to use the CUSUM approach to investigate the number of cases required to reach a consistent, desired performance level for RCID.
Materials and methods: A retrospective study of the first 27 and 28 RCID cases performed by two new fellowship-trained faculty at two separate institutions from November 2014 to January 2018… More >

Abstract The epoxy resin (EMBHBC) of (2E,6E)-bis (4-hydroxybenzylidene)-4-methyl cyclohexanone (MBHBC) was synthesized by condensing 0.5 mol MBHBC and 2.5 mol epichlorohydrin in 500 mL isopropyl alcohol as a solvent and 1.0 mol NaOH in 50 mL water as a catalyst at 80°C for 3 h. The structure of EMBHBC was supported by UV-Vis, FTIR, ¹ HNMR and ¹³CNMR spectroscopic techniques. Molecular weights and molecular weight distribution of EMBHBC were determined by gel permeation chromatography. DSC thermogram of EMBHC showed one endothermic transition (95.9°C) and two exothermic transitions (317.7°C and 382.2°C) due to melting and decomposition transitions, respectively. More >

Abstract This paper provides an analysis of the thermal performance of aerogel insulation used during a long-term International Space Station (ISS) flight experiment aboard Space Test Program – Houston 3 (STP-H3). The Variable emissivity device Aerogel insulation blanket, Dual zone thermal control Experiment suite for Responsive space (VADER) investigation tested a variable emissivity radiator and a new form of multi-layer insulation that used aerogel as the thermal isolator. An effort was made to evaluate the performance of the aerogel insulation over the active flight period. The available flight temperature data shows no evidence of deterioration or More >

Abstract This work presents a review of the research recent results concerning the augmentation of hydrodynamic and thermal performance of various twisted tape inserts in heat exchanger tubes. The thermal and hydrodynamic correlations for various twisted tape elements have been summarized. A comparative study of thermal and hydrodynamic performance of numerous twisted elements has also been reported to understand the result of applications of twisted tape inserts in heat exchanger tubes. The literature review found that multiple twisted tapes heat exchanger tube shape enhanced hydrodynamic and thermal performance than other comparable twisted tape inserts heat exchanger More >

Abstract Solidification of casting is a complex phenomenon which requires accurate input to simulate for real time applications. Interfacial heat transfer coefficient (IHTC) is an important input parameter for the simulation process. The IHTC is varying with respect to time during solidification and the exact value is to be given as input for the accurate simulation of the casting process. In this work an attempt is made to estimate the IHTC during solidification of spherical shaped aluminum alloy component with sand mould. The mould surface heat flux and mould surface temperatures are estimated by inverse control More >

Abstract Dans un contexte où le vandalisme de l’information géographique volontaire constitue une réelle menace pour la qualité des données, cet article propose une technique permettant de le détecter. Tout d’abord, nous examinons les différentes définitions du vandalisme, mettant en avant la complexité de cette notion. Une étude des cas déjà avérés de vandalisme dans OpenStreetMap (OSM) est présentée. Puis, nous expérimentons la détection du vandalisme des données OSM en utilisant une méthode de détection d’anomalie par classification non supervisée. L’analyse de nos résultats initiaux conduit alors à une discussion sur la pertinence de construire un More >

Abstract While shadow can give useful information about size and shape of objects, it can pose problems in feature detection and object detection, thereby, it represents one of the major perturbator phenomenons frequently occurring on images and unfortunately, it is inevitable. “Shadows may lead to the failure of image analysis processes and also cause a poor quality of information which in turn leads to problems in implementation of algorithms.” (Mahajan and Bajpayee, 2015). It also affects multiple image analysis applications, whereby shadow cast by buildings deteriorate the spectral values of the surfaces. Therefore, its presence causes More >
