Abstract—The objective of this work was to develop a theoretical model to study the dynamic thermal behavior of a flat plate solar collector integrated with a phase change material (PCM). The PCM acted as a heat source for the solar system during low intensity solar radiation and night. The energy balance equations for the various components of the collector as well as for the PCM were formulat...

زمینه و هدف: بیماری کبد چرب غیرالکلی رایج‌ترین کبدی است که در حال پیشرفت بوده بیش از یک‌چهارم مردم جهان را درگیر خود ساخته است. این پژوهشگران معتقدند فعالیت ورزشی استفاده داروهای گیاهی با خواص ضدچربی ضداکسایشی می‌تواند به‌عنوان درمان مکمل، سودمند باشد. بنابراین، هدف پژوهش تعیین آثار هشت هفته تمرین هوازی یا مصرف عرق آرتیشو بر سطوح چربی سرمی آنزیم‌های زنان مبتلا به بود. مواد روش‌ها: بدین‌منظور، 2...

OBJECTIVE To determine the effect of intensive patient-centered management (PCM) on service utilization and survival. STUDY DESIGN Prospective cohort study of 756 patients in California who had a life-limiting diagnosis with multiple comorbid conditions (75% were oncology patients) and who were covered by a large commercial health maintenance organization from February 2003 through December 2...

The phase change material (PCM) used in a building wall can reduce building energy consumption and improve the living comfort level. However, only when the temperature of the PCM layer is between phase transition temperature ranges can it have the maximum effect to increase the thermal inertia. How to select the suitable PCM according to the local weather and building wall always troubles build...

In this paper, we propose a novel sensor structure based on the rectangular ring resonator with the photonic crystal microcavity (PCM), and optimize the structure using finite-difference time-domain (FDTD) method. This sensor consists of the rectangular resonator with total internal reflection mirror and the PCM, which can be placed at the nearby optical waveguide of the rectangular ring resona...

Image quality assessment (IQA) methods play important roles in many applications such as image communication, reception, compression, restoration, and display. No-reference IQA metrics are required to resolve an image when there is a lack of a reference image that is required for fullreference IQA metrics. We propose a no-reference IQA method to evaluate the image quality by using the differenc...

Plasma cell myeloma (PCM) is a devastating disease with a highly heterogeneous outcome, with survival ranging from a few months to longer than 10 years. Treatment of multiple myeloma has changed markedly in the past decade due to the development of new drugs such as bortezomib, lenalidomide and thalidomide, which have greatly improved the outcome of PCM. The clinical and prognostic value of imm...

In articular cartilage, chondrocytes are surrounded by a narrow region called the pericellular matrix (PCM), which is biochemically, structurally, and mechanically distinct from the bulk extracellular matrix (ECM). Although multiple techniques have been used to measure the mechanical properties of the PCM using isolated chondrons (the PCM with enclosed cells), few studies have measured the biom...

Centriolar satellites were initially identified as electrondense spherical granules, approximately 70-100 nm in diameter, localized around the centrosomes. We have previously identified pericentriolar material 1 (PCM-1), with a molecular mass of approximately 230 kDa, as a component of centriolar satellites. We now show by immunofluorescence microscopy that these granules are not only concentra...

Phase-change memory (PCM) is an important class of data storage, yet lowering the programming current of individual devices is known to be a significant challenge. Here we improve the energy-efficiency of PCM by placing a graphene layer at the interface between the phase-change material, Ge2Sb2Te5 (GST), and the bottom electrode (W) heater. Graphene-PCM (G-PCM) devices have ∼40% lower RESET cur...
