2017
The siphon breaking phenomenon was investigated experimentally and a theoretical model was proposed. A simulation program based on the theoretical model was developed and the results of the simulation program were compared with experimental results. It was concluded that the results of the simulation program matched the experimental results well.

Circuit Breaker and Fuse Selection

2024
A circuit breaker is a device engineered to interrupt fault currents and sometimes reclose automatically. When a fault current is detected, the breaker separates the electrical contacts, which generates an arc. This arc is extinguished by methods such as elongation, cooling, or splitting, depending on the breaker's design. Breakers are categorized based on the voltage they operate at and the medium used for arc extinction, such as air, oil, SF6 gas, or vacuum. In high-voltage systems, circuit...

Assessing the Structural Integrity of the Dorsal Longitudinal Muscle Neuromuscular Junctions in Drosophila

2025
This video demonstrates a protocol for assessing the structural integrity of neuromuscular junctions in the dorsal longitudinal muscles of Drosophila. The procedure involves staining neurons and muscles with two distinct antibodies and comparing fluorescence patterns between mutant and wild-type flies. A reduction in neuronal staining in mutant flies indicates neurodegeneration, while the muscle structure remains intact.

Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

Presented here is a video analysis pipeline that overcomes challenges in behavioral monitoring within MRI environments, allowing for the detection of uninstructed behavioral responses to external cues. This analysis will facilitate a more comprehensive understanding of evoked internal state changes and brain-wide activity.
FAQs
Beaker graduations provide only rough volume estimates, so they help indicate approximate liquid quantities during routine preparation but do not establish volumetric accuracy. This limitation matters when preparing solutions or combining reactants, because the vessel supports mixing and handling rather than precise measurement. Chemists should therefore treat its markings as guides for approximate amounts.
The wide mouth gives access for adding solids and using a stirring implement, while the cylindrical body provides space for liquids and suspended material to mix. Its flat base allows the vessel to stand during preparation. Together, these features make it practical for dissolving solids, stirring reactions, and preparing solutions without requiring a specialized shape.
Both glass and heat-resistant plastic can serve as beaker materials, but their suitability depends on the task and the vessel’s resistance to the intended conditions. Glass beakers are commonly associated with laboratory handling, while heat-resistant plastic provides another option for routine work. The material should be appropriate when samples are held, mixed, transferred, or warmed.
Its graduations are designed for rough estimation rather than precise measurement. A beaker can still hold liquids, combine components, and support solution preparation, but the indicated volume should not be treated as exact. Recognizing this distinction helps chemists select the vessel for routine preparation while avoiding inaccurate results in procedures that depend on volumetric precision.
A typical workflow is to place the solid and liquid in the vessel, use the open access to stir the mixture, and continue mixing until the solid dissolves. If appropriate for the procedure, the sample can also be warmed on a hot plate. The beaker then supports routine preparation without implying precise volume control.
The pouring spout provides a defined edge for directing liquid during transfer. After a mixture or sample has been held or prepared, the user can pour it into another vessel rather than transferring it with a separate operation. This feature complements the beaker’s role in routine handling, especially when approximate rather than volumetrically exact transfer is sufficient.
Beakers are useful when a procedure emphasizes holding, mixing, stirring, dissolving, warming, or transferring liquids rather than precise measurement. Their simple design and durable construction support routine preparation and classroom demonstrations. They are therefore suitable for visible, general-purpose chemical work in which approximate volumes and straightforward handling meet the experimental need.
A beaker can hold a liquid or mixture while it is warmed on a hot plate, supporting tasks such as preparing solutions or assisting dissolution. The vessel’s flat base allows it to stand during heating, while its construction may be glass or heat-resistant plastic. The procedure remains focused on warming and mixing, not exact volume measurement.
