A study was performed to assess the effect of clockwise rotational torque onto the fracture configuration in unstable intertrochanteric fractures. The premise is that rotational torque in the sagittal plane imparted during screw insertion can lead to a potentially unstable construct in LEFT-sided DHS fixations when compared to the RIGHT-sided ones. This(More)
BACKGROUND Recent research using serum high sensitivity C-reactive protein (hs-CRP) has evidenced existence of low grade systemic inflammation in asthmatics whose correlation with various clinical indices is not fully studied. OBJECTIVE To investigate the relationship between systemic inflammation and various clinical and treatment characteristics of(More)
This paper proposes a generalized space vector pulse width modulation (SVPWM) technique for hybrid multilevel inverters for minimizing total harmonic distortion (THD). The proposed method easily determines the actual location of the instantaneous reference space vector and the corresponding switching sequence of a multilevel inverter. The proposed algorithm(More)
In this paper presents a survey on RoF for Wireless Broadband Access technology like WiMAX (Fixed and Mobile). RoF is considered to achieve an effective delivery of wireless and baseband signal, and it also reduces the power consumption. In the other hand WiMAX (Worldwide Interoperability for Microwave Access) is recent fast growing broadband access(More)
An attempt was made to develop a computational model based on artificial neural network and ant colony optimization to estimate the composition of medium components for maximizing the productivity of Penicillin G Acylase (PGA) enzyme from Escherichia coli DH5α strain harboring the plasmid pPROPAC. As a first step, an artificial neural network (ANN) model(More)
