The piezoelectric actuator (PEA) is a well-known device for managing extremely small displacements in the range from 10 pm (1 pm = 10 12 m) to 100 m. When developing a control system for a piezo-actuated positioning mechanism, the actuator dynamics have to be taken into account. An electromechanical piezo model, based on physical principles, is presented in this paper. In this model, a first-or...

This paper proposes a generalized nonlinear minor component analysis algorithm. First, we will prove that with appropriate nonlinear functions the proposed algorithm can extract adaptively the minor component. Then we will discuss how to choose the related nonlinear functions so as to guarantee the desired convergence. Furthermore, we will show that all the other available minor component analy...

Replenishing nutrients through organic sources is essential to maintain the soil health and sustainability in Eastern Himalayan Region, India which is organic by default. Keeping this in mind an experiment was laid out on randomized block design with six treatments viz., T1: Vermicompost (VC; 2.5 Mg ha-1), T2: Poultry manure (PM; 1.25 Mg ha-1), T3: Swine manure (SM; 3.0 Mg ha-1), T4: Cow du...

the purpose of this research study is to check the overall job satisfaction associate with demographic factors: gender, age, ethnicity, civil status, experience, educational qualification, bank types and distance to working place in ampara region, sri lanka government and private bank employees. overall job satisfaction can be measured through the ability utilization, motivation, social status,...

Traumatic brain injury (TBI) is described by a disruption in the normal function of the brain due to an injury following a trauma, which can potentially cause severe physical, cognitive, and emotional impairment. The use of human stem cells and self-assembling peptide scaffolds suggest huge potential for application in the treatment of TBI. In the present study, we surveyed the beneficial effec...

Antimicrobial peptides (APs) are important components of the innate defenses of animals, plants, and microorganisms. However, some bacterial pathogens are resistant to the action of APs. For example, Proteus mirabilis is highly resistant to the action of APs, such as polymyxin B (PM), protegrin, and the synthetic protegrin analog IB-367. To better understand this resistance, a transposon mutage...

BACKGROUND Relatively little is known regarding after-school behavior. This study examined after-school active and sedentary behaviors among youth participating in the Study of Early Child Care and Youth Development. METHODS An interview guided time-use approach was used to obtain detailed longitudinal information about after-school (3-6 PM) behavior of a mixed gender cohort (n = 886) at ages...

Hyperglycemic conditions of diabetes accelerate protein modifications by glucose leading to the accumulation of advanced glycation end-products (AGEs). We have investigated the conversion of protein-Amadori intermediate to protein-AGE and the mechanism of its inhibition by pyridoxamine (PM), a potent AGE inhibitor that has been shown to prevent diabetic complications in animal models. During in...

Particulate matter (PM) air pollution exerts significant adverse health effects in global populations, particularly in developing countries with extensive air pollution. Understanding of the mechanisms of PM-induced health effects including the risk for cardiovascular diseases remains limited. In addition to the direct cellular physiological responses such as mitochondrial dysfunction and oxida...
