A numerical parametric study is presented of a domestic thermal storage heat exchanger to explore the effect highly localized positive temperature coefficient cylindrical heating elements in phase change material (PCM) with conductive enhancement by open-pore metal foam. By using 90 L commercially available Rubitherm RT70HC wax, 5.7 kWh energy captured unit. The discharge via central convective...

INTRODUCTION: Structure and composition of articular cartilage as well as metabolic activity of chondrocytes (cartilage cells) change in osteoarthritis (OA) [1]. Among these changes, cell volume has been reported to increase [1,2]. Furthermore, the structure, composition and mechanical properties of the pericellular matrix (PCM) alter in OA [3]. However, the role of PCM in modulating volumetric...

Three hundred and fifty-two patients with alcoholic hepatitis were evaluated for protein-calorie malnutrition (PCM). In order to facilitate data analysis of nutritional status, a PCM score was calculated for each patient using eight nutritional parameters. The PCM score correlated significantly with mortality, clinical severity of the liver disease, and biochemical liver dysfunction. When 30 da...

Latent heat thermal energy storage (LHTES) systems can be used to combat the limited collection and long-term of renewable sources. The key component an LHTES system is its phase change material (PCM), which thermally stores energy. Despite extensive research on conductivity enhancement within PCM, little attention has been paid transfer fluid (HTF) system. This study aimed observe impact varia...

The pericellular matrix (PCM) is a narrow region that is rich in type VI collagen that surrounds each chondrocyte within the extracellular matrix (ECM) of articular cartilage. Previous studies have demonstrated that the chondrocyte micromechanical environment depends on the relative properties of the chondrocyte, its PCM and the ECM. The objective of this study was to measure the influence of t...

Phase change memory (PCM) is a promising memory technology that can offer higher memory capacity than DRAM. Unfortunately, PCM’s access latencies and energies are higher than DRAM and its endurance is lower. DRAM-PCM hybrid memory systems use DRAM as a cache to PCM, to achieve the low access latencies and energies, and high endurance of DRAM, while taking advantage of the large PCM capacity. A ...

BACKGROUND centrosomes are major microtubule organizing centers in animal cells, and they comprise a pair of centrioles surrounded by an amorphous pericentriolar material (PCM). Centrosome size is tightly regulated during the cell cycle, and it has recently been shown that the two centrosomes in certain stem cells are often asymmetric in size. There is compelling evidence that centrioles influe...

Phase change memory (PCM) is a promising alternative to DRAM, though its high latency and energy costs prohibit its adoption as a drop-in DRAM replacement. Hybrid memory systems comprising DRAM and PCM attempt to achieve the low access latencies of DRAM at the large capacities of PCM. However, known solutions neglect to assess the utility of data placed in DRAM, and hence fail to achieve high p...

In this research, myristic-palmitic acid(MA-PA)/ nano silicon dioxide(nano-SiO2) was modified by adding carbide(nano-SiC) with high thermal conductivity. The MA-PA/nano-SiO2 composite phase change material (PCM) prepared impregnating the MA-PA eutectic mixture as PCM into nano-SiO2 supporting material. Nano- SiC added to improve conductivity of PCM. Leakage experiments demonstrated that optimal...
