indirect immunofluorescence (iif) has been used to identify and measure autoantibody levels in pemphigus vulgaris but data about relationship between clinical severity of disease and antibody titers by iif have been conflicting. we conducted this cross-sectional study to correlate the severity of oral and/or cutaneous involvement in patients with pemphigus vulgaris based on pemphigus area and a...

This paper sought to evaluate the influence of entrepreneurial education on informal entrepreneur’s intention formalise. A positivist approach was employed backed by quantitative analysis determine impact formalise businesses. The study analysed a sample 265 traders and structured questionnaire used gather data. Collected data using parameters such as regression Pearson correlation analysis. re...

Abstract The machinability of Ti-6Al-4V alloy has been a constant challenge in the industry, although material is widely used aerospace and medical industries due to its mechanical properties, particularly strength-to-weight ratio. current research presents hybrid laser- ultrasonic-assisted machining (LUAM) technique improve turning process. This compared with (UAM), laser-assisted (LAM), conve...

air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. so2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. symbiosis of rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...

Induction motor drives using field oriented control (FOC) for torque and flux control have been used in high performance industrial applications instead of dc motors for many years. In FOC, torque and flux of an induction motor can be controlled independently by decoupling the stator current into its orthogonal components. The FOC method has achieved a quick torque response. But in order to ach...

The electrical conductivity and the thermal performance of the films made of reduced graphene oxide (rGO) spray-coated on polycarbonate substrate were investigated. The electrical conductivity and the transmittance of 10 times spray coated film made from the solution with 0.08 wt% of rGO, 0.16 wt% of surfactant were 30 komega/sq and 64%, respectively. The steady-state temperature of the films i...

Replication of natural mixing through artificial water circulation techniques, such as convectional systems (CWCS), can break thermal stratification in stagnant and suppress algal blooms. Here, the field performance a novel CWCS was evaluated eutrophic reservoir (Shingal reservoir, South Korea) for three seasons between September 2016 2018. The deployed corner stagnated reservoir. changes tempe...

The study presented the design of an efficient motorized antenna positioning control system using Model Following Control (MFC). It was desired to a improve stability and reduce position error. dynamic model direct current (DC) servomotor developed achieve this. An MFC designed that integrated Proportional Integral Derivative (PID) controller in frequency domain for tuning loop terms transient ...

Energy transfer in mixed convection unsteady magnetohydrodynamic (MHD) flow of an incompressible nanofluid inside a channel filled with saturated porous medium is investigated. The channel with non-uniform walls temperature is taken in a vertical direction under the influence of a transverse magnetic field. Based on the physical boundary conditions, three different flow situations are discussed...
