Sputtering is an important physical vapor deposition (PVD) method in the manufacture of many products. However, sputtering processes are prone to arcing, which can cause damage to the work piece. Therefore, arcs must be detected and extinguished in a timely manner to minimize damage. Instantaneous arc rate and total arcs per process step are useful data for assessing PVD chamber health, and det...

I discuss the effect of non-radial motions on the small-scale pairwise peculiar velocity dispersions of galaxies (PVD) in a CDM model. I calculate the PVD for the SCDM model by means of the refined cosmic virial theorem (CVT) (Suto & Jing 1997 (hereafter SJ97)) and taking account of non-radial motions by means of Del Popolo & Gambera (1998) (hereafter DG98) model. I compare the results of the p...

MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression by post-transcriptional inhibition of mRNA translation. Dysregulation of miRNAs, including circulating miRNAs, has been reported to play an important role in the development of various diseases, including fibrotic diseases. Aberrant expression of miRNAs in the vitreous humor of vitreoretinal diseased eyes has been reporte...

The peripheral nerve pathology in ischaemic limbs with atherosclerotic peripheral vascular diseases (PVD) is difficult to ascertain because of the limited number of reports. In addition, it has been debated whether chronic ischaemia per se could cause morphological abnormalities in peripheral nerves. In this prospective study, we examined pathological findings in the sural, saphenous, deep pero...

Provoked vestibulodynia (PVD) refers to vulvar pain of at least 3 months duration, localized to the vestibule, provoked by touch and sexual activity and occurring in the absence of a clear identifiable cause. The clinical spectrum ranges from mild with distressing discomfort through to severe and disabling pain. Current understanding is that PVD is one of many chronic pain conditions characteri...

Purpose: To evaluate the efficacy of autologous plasmin in pediatric vitrectomy and to report the anatomic outcomes of autologous plasmin assisted pediatric vitrectomy Methods: In an interventional prospective study, Thirty-four pediatric patients with vitreoretinal disorders who needed vitrectomy during 2008 to 2010, included in the study. The patients were divided into two groups: the retinop...

PURPOSE To compare the incidence of posterior vitreous detachment (PVD) after femtosecond and microkeratome laser in situ keratomileusis (LASIK). SETTING Rowad Correction Centre, Cairo, Egypt (a private center affiliated to Cairo University). DESIGN Prospective, nonrandomized comparative unmasked study. METHODS The study was conducted at a single laser center. Eligible patients chose betw...

Recognizing the importance of improving lung health through lung disease research, the National Heart, Lung, and Blood Institute (NHLBI) convened a workshop of multidisciplinary experts for the following purpose: (1) to review the current scientific knowledge underlying the basis for treatment of adults and children with pulmonary vascular diseases (PVDs); (2) to identify gaps, barriers, and em...

Pulmonary arterial hypertension (PAH) is a frequent complication of congenital heart disease as a consequence of altered pulmonary hemodynamics with increased pulmonary blood flow and pressure. The development of pulmonary vascular disease (PVD) in this patient population is an important concern in determining operative strategy. Early, definitive surgical repair, when possible, is the best the...

The PVD techniques range over a wide variety of applications from decorative, to high temperature superconducting films. The thickness of the deposits can vary from angstroms to millimeters. A very large number of inorganic materials—metals, alloys, compounds, and mixtures—as well as some organic materials can be deposited using Physical vapour Deposition (PVD) technologies. Traditionally, the ...
