Voltage collapse and blackout can occur in an electric power system when load powers vary so that the system loses stability in a saddle node bifurcation. We propose new iterative and direct methods to compute load powers a t which bifurcation occurs and which are locally closest to the current operating load powers. The distance in load power parameter space to this locally closest bifurcation...

Among clinicians, it is common practice to include parents in treatment, and it has been taken for granted that parents' involvement in their children's treatment is beneficial for therapy outcome, although research on this issue is far from clear. A meta-analysis was carried out in order to investigate whether parent involvement potentiates the outcome for children with anxiety disorders when ...

BACKGROUND Circulating insulin levels have been positively associated with risk of colorectal cancer; however, it remains unclear whether a diet inducing an elevated insulin response influences colorectal cancer risk. On the basis of a novel insulin index for individual foods, we estimated insulin demand for overall diets and assessed its association with colorectal cancer in the Nurses' Health...

OBJECTIVE To investigate the association between the glycemic index and the glycemic load of the diet with the risk of overweight and high adiposity in children with 5 years of age. METHODS Cross-sectional study nested in a cohort of 232 children born and living in Diamantina (MG, Brazil). Parents and/or guardians provided the food intake data, using a semiquantitative food frequency question...

The reliability index is an important reliability parameter that is necessary for the development of reliability-based geotechnical design. Both the factor of safety (FS) and the reliability index (β) represent safety margin of structures against either failure or limit state. In this study, the reliability index is analyzed and evaluated in reference to the factor of safety currently adopted i...

Diets with a high glycemic index and glycemic load have been hypothesized to be implicated in the etiology of colorectal cancer owing to their potential to increase postprandial glucose and insulin levels. Prospective data on glycemic index and glycemic load in relation to colorectal cancer risk are limited and inconsistent. Therefore, the authors prospectively investigated the associations of ...

Cloud computing is a model that points at streamlining the on-demand provisioning of software, hardware and data as services and providing end-users with flexible and scalable services accessible through the Internet. The main objective of the proposed approach is to maximize the resource utilization and provide a good balanced load among all the resources in cloud servers. Initially, a load mo...

This dissertation intends to examine the effects of task-induced involvement load on L2 incidental vocabulary acquisition through reading. Task-induced is operationalized manipulating components need, search and evaluation show relevance acquisition. It will intend do this by using three major variables: load, initial learning medium-term retention. The chapter starts providing reasons for why ...
