one of the ecient and powerful schemes to solve linear and nonlinear equationsis homotopy analysis method (ham). in this work, we obtain the approximate solution ofa system of partial dierential equations (pdes) by means of ham. for this purpose, wedevelop the concept of ham for a system of pdes as a matrix form. then, we prove theconvergence theorem and apply the proposed method to nd the a...

background: epilepsy is defined as recurrent unprovoked febrile  seizures, which  cause  disability in patients.  this study  aims  to  assess  the  health-related  quality-of-life (qol) in epileptic patients in fars province, southern  iran. methods: one-hundred epileptic  patients, above 18 years, referred to shiraz university of medical sciences affiliated clinics, were included. the qol of ...

Fertilizer has brought great pressure to sustainable ecological environment. Research on the effect of price fertilizer use as well substitution relationship and other input factors agricultural production is importance for green, efficient, intensive in world. This study first constructs translog cost functions models elasticity, then uses factor data from 2004 2016 measure elasticity demand, ...

The net effects of switching from consumption taxation to inflation taxation on resource allocation and welfare crucially depend on production externalities. With elastic labor supply, raising inflation taxation decreases leisure, but increases the levels of real consumption, capital, and output. Moreover, this tax switch has two opposing effects on the level of real money balances: A positive ...

In recent years, a growing body of the literature in international trade tried to investigate whether openness has been increasing labour demand elasticities. From a labour theory perspective in partial equilibrium, the Allen-Hamermesh theoretical framework became one of the few general frameworks to refer to1. This theory states that labour demand elasticity should be positively affected by it...

the use of plant fibers in producing different industrial products has attracted the attention of many researchers. plant fibers, in comparison with industrial ones, are degraded faster in nature and are more environments friendly. one of the major conventional uses of plant fibers is the production of traditional ropes which are subjected to tensile forces. however, the traditional ropes bear ...

Dermal elastic fibres are extracellular matrix protein complexes produced by fibroblasts and involved in skin elasticity. Elastin fibres decrease with age as a result of reduced synthesis and increased degradation, resulting in skin sagging and reduced skin elasticity. In this study, we show that retinol (ROL), known to enhance dermal collagen production, is also enhancing elastin fibre formati...

The variational principle of the Onsager–Machlup integral is used to describe stochastic dynamics a micromachine, such as an enzyme, characterized by odd elasticity. obtained most probable path found become non-reciprocal in presence elasticity and further related entropy production.
