A primary impediment to understanding how species diversity and anthropogenic disturbance are related is that both diversity and disturbance can depend on the scales at which they are sampled. While the scale dependence of diversity estimation has received substantial attention, the scale dependence of disturbance estimation has been essentially overlooked. Here, we break from conventional exam...

Purpose Resistance is expected to emerge with the implementation and use of new technologies in production systems. This work focuses on identifying sources resistance Industry 4.0 when managing disturbances suitable managerial approaches deal them. Design/methodology/approach A qualitative approach was chosen this research. The authors conducted a literature review series interviews. Thirty-on...

Using Tracking Differentiators in Designing Nonlinear Disturbance Observers for Uncertain SystemsNaser Kazemzadeh, Saeed BarghandanAbstractIn the present paper, a practical designing method has been proposed for a novel class of NDOs based on TD. Such NDOs can nearly estimate all uncertain disturbances (specifically disturbances without prediction information). Regarding the outstanding perform...

restless leg syndrome (rls) is a common cause of painful legs. the leg pain of restless leg syndrome typically eases with motion of the legs and becomes more noticeable at rest. stress or emotional upset can make symptoms worse. the purpose of the present study was to examine the relationship of emotional disturbance and quality of life to the severity of rls. using a descriptive-correlational ...

Silviculture (logging) creates a disturbance to forested environments. The degree to which forests are modified depends on the logging prescription and forest stand characteristics. In this study we compared the effects of two methods of group-selection ("moderate" and "heavy") silviculture (GSS) and undisturbed reference stands on stress and offspring sex ratios of a forest interior species, t...

Ore grinding system is a multivariable mechanism which is used in mining industry, metallurgy, cement production, chemicals, pharmaceuticals, ceramics and various research laboratories. Previous control methods of this system include open multi-loop PID controller, Model Predictive Control (MPC), adaptive control and robust control. The mentioned techniques do not show proper performance, when ...

background: the present work was conducted to study the burn patients’ experiences to get an insight into their main concerns when they suffer the tragic event, recover from it, and adjust back in the society, so that better rehabilitation programs can be planned corresponding to their needs as well as to the needs of the society and the existing situations. materials and methods: in this quali...

BACKGROUND Understanding the process of relapse to abused drugs and ultimately developing treatments that can reduce the incidence of relapse remains the primary goal for the study of substance dependence. Therefore, exploring the metabolite characteristics during the relapse stage is valuable. METHODS A heroin self-administered rat model was employed, and analysis of the 1H-nuclear magnetic ...
