Curing Methods

Curing Methods

Concrete members with a small surface-to-volume ratio are cured by oiling and moistening the forms before casting the concrete member. These forms can be left in place for a prolonged period to prevent moisture loss, and can be wetted if made of a material suitable for wetting. If the forms are removed early, the concrete member is moistened and covered with polythene sheets to maintain moisture. For large horizontal concrete surfaces exposed to dry weather, a temporary covering is suspended...

Load-frequency control

Load-frequency control

Load-frequency control (LFC) is vital for maintaining power system stability, ensuring that frequency and power flows remain within acceptable limits during load changes. Turbine-governor control eliminates rotor accelerations and decelerations following load changes. However, a steady-state frequency error persists when the change in the turbine-governor reference setting is zero. In an interconnected power system, each area agrees to export or import a scheduled amount of power through...

Lift

Lift

Lift is a fundamental aerodynamic force that acts perpendicular to the direction of airflow. It plays a central role in achieving and sustaining flight and in stabilizing various vehicles. Lift primarily originates from pressure differences created across surfaces, such as an airfoil. A lower pressure region forms above the wing, while a higher pressure region forms below it, generating an upward force. This differential results from the shape and orientation of the airfoil, enabling the wing...

Lampbrush Chromosomes

Lampbrush Chromosomes

In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops resemble the...

Reducing Line Loss

Reducing Line Loss

In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

Area of Science:

Public Health
Community Health Interventions
Obesity Prevention

Background:

Kentucky experiences high rates of adult obesity and physical inactivity.
These conditions pose significant health risks (cardiovascular disease, diabetes, cancer) and community costs (healthcare, absenteeism).

Purpose of the Study:

To describe the implementation and outcomes of community-based lifestyle change programs.
To encourage community members towards healthier lifestyles through education and physical activity.

Main Methods:

The Lite'n Up Hopkins County program included baseline and follow-up physical activity assessments and health education.
The Walk'n Kentucky program offered opportunities for increased daily physical activity and health education.

Main Results:

Walk'n Kentucky participants collectively walked over 20,533 miles, with some achieving significant weight loss (13-31 pounds).
Lite'n Up participants showed improvements: 70% of high schoolers improved mile times, and 95% of middle schoolers improved mile times.
A small percentage of high school students with at-risk BMIs improved their weight classifications.

Conclusions:

Community-based programs can effectively promote physical activity and contribute to weight management.
Program challenges included lower participation in follow-up assessments and scheduling difficulties.
