The power system nonlinearity and its profound impact on the individual states of power system is first evaluated and the interaction between their constituent modes during the occurrence of internal mode resonance (IMR) is discussed in this paper. A typical dynamical feature of nonlinear systems is the frequency-energy dependence of their states and their corresponding constituent modes which ...

The influence of lipid composition, internal pH and internal buffering capacity on the retention properties of vincristine loaded into large unilamellar vesicle (LUV) systems in response to transmembrane pH gradients has been assessed. It is shown that increasing the (saturated) acyl chain length of the phosphatidylcholine molecule, increasing the internal buffering capacity, and decreasing the...

indubitably, the efficacy of metalinguistic awareness in improving efl learners’ grammatical knowledge and writing quality has long been an area of great interest in applied linguistics brown (2001). accordingly, the main objective of the present study was to investigate the impact of planned and unplanned focus on form instruction on students’ ability to learn grammar and use it appropriately ...

in this paper, an analytical solution for computing the linear plastic stresses and critical pressure in a fgm hollow cylinder under the internal pressure due to non-axisymmetric loads is developed. it has been assumed that the modulus of elasticity was varying through thickness of the fgm material according to a power law relationship. the poisson's ratio was considered constant throughou...

Malignant Mesothelioma (MM) is a rare form of cancer that affects the thin cell wall lining of the body's internal organs and structures.[...].

background: we aimed to create a shortened form of the champion health belief model instrument which is a widely used questionnaire about breast cancer screening behaviors with acceptable validity and reliability. methods: the persian version of the champion health belief model (chbm) instrument consists of 57 items in 8 concepts. the subjects of the study were 40 female faculty members and 34 ...

Spatial relationships between the internal nucleolus-associated chromatin (NAC) and the numerous nucleolar vacuoles that appear during early germination have been studied in nucleoli of quiescent (non-germinated) and early germinating embryos of Sinapis using serial sections. In quiescent non-vacuolated nucleoli, the transcriptionally inactive internal NAC is a short strand about 900 nm thick t...

Objectives. The availability of a valid, reliable, and suitable tool that accurately measures and differentiates anxiety levels of children is crucial before designing appropriate interventions to minimize their apprehension and enhance their coping ability. Regrettably, there is a lack of such a simplified instrument for use in busy clinical settings where time constrains makes the use of more...
