The Trowell-type organ culture method has been used to unravel complex signaling networks that govern tooth development and, more recently, for studying regulation involved in stem cells of the continuously growing mouse incisor. Fluorescent-reporter animal models and live-imaging methods facilitate in-depth analyses of dental stem cells and their specific niche microenvironment.

Source:Alessia J. Marchesan1, Guillermo Hernandez Ramirez11Renewable Resources, University of Alberta. This video demonstrates the technique for collecting a soil sample for hydraulic property analysis. The sampling area is cleared, and the top crust is evacuated. The sampling ring is then placed into the soil to collect the sample. The ring with the sample is then cleaned, labeled, packed, and transferred undisturbed for analysis.

Repeated soil sampling has recently been shown to be an effective way to monitor forest soil change over years and decades. To support its use, a protocol is presented that synthesizes the latest information on soil resampling methods to aid in the design and implementation of successful soil monitoring programs.

Source: Laboratories of Dr. Ian Pepper and Dr. Charles Gerba - The University of Arizona Demonstrating Author: Bradley Schmitz Soils normally contain a finite amount of water, which can be expressed as the “soil moisture content.” This moisture exists within the pore spaces in between soil aggregates (inter-aggregate pore space) and within soil aggregates (intra-aggregate pore space) (Figure 1). Normally this pore space is occupied by air and/or water. If all the pores are occupied by air, the...

This article details the construction of a multiplexed microneedle-based sensor. The device is being developed for in situ sampling and electrochemical analysis of multiple analytes in a rapid and selective manner. We envision clinical medicine and biomedical research uses for these microneedle-based sensors.
FAQs
Blade angle and applied pressure determine how much material remains on the surface and how evenly it is distributed. A controlled angle supports consistent coverage, while pressure can help compact material and reduce voids or uneven areas. Adjusting both variables allows the operator to influence thickness, texture, smoothness, and dimensional consistency without changing the material itself.
A trowel’s flat or shaped blade affects how an operator scoops, places, spreads, levels, or finishes workable material. Flat blades support broad distribution and smoothing, while shaped blades can help control placement in particular areas. Selecting the blade according to the task improves handling of mortar, plaster, grout, or concrete during surface preparation and finishing.
Workability strongly influences how successfully material can be placed, compacted, leveled, and smoothed with a trowel. Mortar, plaster, grout, and concrete can require different handling because their behavior affects coverage, thickness control, and surface texture. The operator must respond to the material’s workable condition through appropriate movement, angle, and pressure to limit waste and irregularities.
By distributing material evenly and pressing it into the intended area, troweling helps limit voids and poorly covered regions that can weaken surface contact. Leveling and smoothing also control the material profile, supporting more consistent dimensions across the treated surface. These effects are important where masonry, flooring, wall finishes, or concrete repairs require both surface quality and reliable coverage.
A basic sequence begins by scooping a workable amount onto the blade, placing it where needed, and distributing it across the surface. The operator then adjusts blade angle and pressure to level or compact the material before smoothing or creating the required finish. This sequence supports controlled thickness while reducing uneven areas and unnecessary material loss.
Troweling supports several construction activities, including masonry, flooring, wall finishing, and concrete repair. In each setting, the technique helps place and refine materials such as mortar, plaster, grout, or concrete. Its value varies with the task: masonry needs controlled placement, flooring requires surface regularity, and finishing or repair work depends on consistent coverage and a suitable surface texture.
Proper technique can produce more uniform surfaces, controlled material thickness, and improved texture. It also helps reduce voids, uneven areas, and material waste by combining deliberate placement with leveling, compaction, and smoothing. These outcomes provide practical quality indicators for construction work, especially when the finished surface must remain dimensionally consistent or support effective adhesion.
