Salt hydrates have issues of supercooling when they are utilized as phase change materials (PCMs). In this research, a new method was adopted to prepare a salt hydrate PCM (based on a mixture of calcium chloride dihydrate and calcium chloride anhydrous) as a novel PCM system to reduce the supercooling phenomenon existing in CaCl₂·6H₂O. Six samples with different compositions of CaCl₂ were prepa...

Background: Regarding the widespread prevalence of chronic diseases, nurses need to understand the choices, priorities, and abilities of patients in reality, their communication, and the social context in order to play their professional role and responsibility. This review study was conducted with two purposes: determining the effect of partnership-care-model (PCM) on the outcomes of chronic d...

Like its homologs throughout the biological world, the L-isoaspartyl protein repair methyltransferase of Escherichia coli, encoded by the pcm gene, can convert abnormal L-isoaspartyl residues in proteins (which form spontaneously from asparaginyl or aspartyl residues) to normal aspartyl residues. Mutations in pcm were reported to greatly reduce survival in stationary phase and when cells were s...

Spectrophotometric techniques were developed for the determination of single and binarymixture Promethazine hydrochloride (PMH) and Paracetamol (PCM). Normal and first derivative (D) used for single drug at λ 249.5 and 243.0 for PMH and 243.5 and 225 for PCM. The simultaneous determination of binary mixture (PMH) and (PCM) were accomplished by first derivative (D) and second derivative (D) spec...

The effect of dimethylsulphoxide (DMSO) on the organization of the microtubular system of the mouse oocyte has been examined. Exposure to DMSO causes the immediate appearance of multiple, cold-resistant microtubular asters associated with the foci of pericentriolar material (PCM) normally present in the oocyte. More prolonged exposure to DMSO leads to progressive disassembly of the spindle, and...

Introduction: paracoccidioidomycosis (PCM) is a polymorphic systemic granulomatous inflammatory disease determined by Paracoccidioides brasiliensis, one of the 10 leading causes of morbidity and mortality among the parasitic diseases endemic in Brazil. Objective: To identify the following aspects of PCM by ultrasound (US) and computed tomography (CT): abdominal changes, intensity and characteri...

A biologically significant relationship between precancerous mastopathy (PCM), in situ carcinoma (ISC), and invasive breast carcinoma is evidenced by the following: (a) PCM and ISC are commonly associated with each other and with invasive breast cancer; (b) Stage O PCM and ISC are both associated with an increased risk of subsequent breast cancer; (c) patients with Stage O PCM and ISC are more ...

Stochastic spectral methods are numerical techniques for approximating solutions to partial differential equations with random parameters. In this work, we present and examine the multi-element probabilistic collocation method (ME-PCM), which is a generalized form of the probabilistic collocation method. In the ME-PCM, the parametric space is discretized and a collocation/cubature grid is presc...
