Wind turbines form complex nonlinear mechanical systems exposed to uncontrolled wind profiles. This makes turbine controller design a challenging task (Athanasius & Zhu, 2009). As such, control of wind energy conversion systems (WECS) is difficult due to the lack of systematic methods to identify requisite robust and sufficiently stable conditions, to guarantee performance. The problem becomes ...

The prefrontal cortex in human brain is the main area that is related to the capacity for establishing relationships to others and with your environment. It is also the core for the development of superior mental functions such as plan and motor outcome, cognitive, affective, and social behavior across time (Kolb et al., 2012). Some cognitive functions related to this lobule include fluid intel...

Acute aortic dissection (AAD) is the third main driver of the out-of-hospital immediate death (Manfredini et al., 2008). Despite the state-of-the-art therapeutic and diagnostic methods, AAD develops hastily with often fatal consequences. Although the AAD was first reported more than two centuries ago there is still less knowledge about the origins and causes of it (Hagan et al., 2000). Environm...

the potential sources of cr (vi) are various effluents from metallurgy, electroplating, leather tanning, textile dyeing, paint, ink, and aluminum manufacturing industries. these industrial effluents can contain cr (vi), in the concentration range of 10 to 100 mg/l (nakano et al 2000), which is much higher than the standard limit; 0.5 mg/l in industrial wastewater (epa). in aqueous systems, chro...

Dye-sensitized solar cell (DSSC) has attracted wide attention for the potential application to convert sunlight into electricity. Organic dyes blended with TiO2 nanoparticles (NPs) have been recognized as important light harvesting materials especially in the visible spectral range (Hara et al., 2002; Bisquert et al., 2002; Gratzel, 2001; Ferrere & Gregg, 2001; Hagfeldt & Gratzel, 2000; Cahen e...

Turbulent solar convection is a source of various processes observed as large-scale active phenomena, e.g., coronal mass ejections, formation of self-organized magnetic structures that appear on the surface as sunspots and pores, and other non-linear dynamical structures and phenomena. Modern realistic numerical simulations of solar turbulent phenomena are based on first physical principles and...

Childhood obesity is a public health challenge in the United States (U.S.) and elsewhere in the world. Additionally, those who are obese are heavier than in the past (Anderson & Butcher, 2006). In the U.S., one in three children is overweight or obese (Ogden et al., 2010), a prevalence that has tripled since 1970 (Anderson & Butcher, 2006; Kumanayika & Grier, 2006; Wang & Zhang, 2006). In respo...

STOCK DEFINITION AND GEOGRAPHIC RANGE Killer whales have been observed in all oceans and seas of the world (Leatherwood and Dahlheim 1978). Although reported from tropical and offshore waters, killer whales occur at higher densities in colder and more productive waters of both hemispheres, with the greatest densities found at high latitudes (Mitchell 1975, Leatherwood and Dahlheim 1978, Forney ...

The new species is a member of an apparently monophyletic group within the genus that includes R. flexile, R. walga, R. himanturi, R. burgeri, R. euzeti, R. hawaiiensis, R. urobatidium, R. paratrygoni, R. ditesticulum, R. tetralobatum, R. margaritense, R. biorchidum, and R. spinicephalum. All of these species have bothridia with medial longitudinal septa, a constriction at mid-bothridium, and, ...

Delirium is a cognitive disorder characterized by acute onset, fluctuating course, altered level of consciousness, inattention, disorganized thinking, disorientation, memory impairment, and perceptual and motor disturbances (American Psychiatric Association, 2000; World Health Organization, 2010). It occurs in hyperactive, hypoactive, or mixed forms in up to 42% of older hospital inpatients (Si...
