The paper presents the theoretical, simulation, and experimental results on QCM sensor based Butterworth van Dyke (BVD) model with lumped reactive motional circuit elements of fractional order. equation order BVD has been derived Caputo definitions its behavior around resonant frequencies simulated. simulations confirm ability calculus to cover a wide range behaviors beyond those found in pract...
Although retinal vasculitis is common in multiple sclerosis (MS), it is not known if MS is associated with quantitative abnormalities in retinal blood vessels (BVs). Optical coherence tomography (OCT) is suitable for examining the integrity of the anterior visual pathways in MS. In this paper we have compared the size and number of retinal blood vessels in patients with MS, with and without a h...
As part of the preparatory phase of a disease control programme in three herds infected with bovine virus diarrhoea-mucosal disease (BVD-MD) virus (demonstrated by virus isolation), initial serological screening was performed on all livestock older than six months (351 animals) by blocking enzyme-linked immunosorbent assay (ELISA) using a monoclonal antibody recognising a common epitope to the ...
Introduction: Livestock husbandry is critical for food security and poverty reduction in a low-income country like Tanzania. Infectious disease is one of the major constraints reducing the productivity in this sector. Peste des petits ruminants (PPR) is one of the most important diseases affecting small ruminants, but other infectious diseases may also be present. Objective: The objective of th...
در این مطالعه عوامل ویروسی مسبب پنومونی گوساله های شیری (پنومونی آنزئوتیک)، در 9 گاوداری استان خراسان رضوی از مهرماه 1387 تا اردیبهشت 1388، مورد مطالعه قرار گرفت. از هر گله 5 گوساله بیمار، جهت معاینه انتخاب شده، و از هر گوساله در دو فاز بیماری (حاد و نقاهت) نمونه سرم، اخذ گردید. نمونه های سرم، به روش الایزای غیر مستقیم از نظر وجود آنتی بادی علیه ویروس های bhv-1 ، bvd ، brs ، pi3 ، bav-3 ، مورد ...
Caries and periodontitis affect the majority of adults during their lifetime. Piezoelectric ultrasonic scalers offer great benefits prevention treatment periodontal diseases. Our group developed a novel scaler based on planar piezoelectric transducer. However, similar to other configurations, transducer’s characteristics are strongly influenced by operation conditions. In this study, we investi...
Abstract Backgrounds Bioprosthetic valve dysfunction (BVD) is a major concern regarding transcatheter aortic implantation (TAVI) in low-risk patients. Aims To assess incidence, determinants, modes, and outcome of early to mid-term BVD after TAVI relation with life expectancy. Methods Consecutive recipients (2007–2020) post-interventional follow-up ≥1-year were prospectively included. components...
BACKGROUND Scalp/neck melanomas have a poor prognosis, possibly because of a rich vascular supply that prompts tumor cells' dissemination. METHODS We compared the accuracy of immunohistochemical (IHC) staining with morphology for the identification of lymphovascular invasion in 156 scalp/neck melanomas. We then analyzed the association of vessel invasion and density with pathological features...
