Drive-Reduction Theory: Push Theory of Motivation01:27

Drive-Reduction Theory: Push Theory of Motivation

1.3K
Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...

Overview of Microscopy Techniques

17.1K
The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Aseptic techniques prevent contamination, ensure experimental accuracy, and protect researchers and microbial cultures. These techniques are essential in clinical, industrial, and research settings where sterility is required.Maintaining Sterility in Laboratory PracticesScientists maintain sterility by sterilizing tools with heat or chemicals, disinfecting work surfaces, and handling cultures in controlled environments. Working near an open flame or within a laminar flow hood reduces the risk...

Brick Cutting Techniques

690
Brick-cutting techniques involve various tools and methods to shape bricks for construction. A mason's hammer with a chisel-pointed end is used for basic shaping through sharp, precise strikes. For more complex shapes requiring higher precision, a power saw with a water-cooled diamond blade is used.
Cut bricks are categorized by size. Bricks cut to half their original length are called half-bats, while those cut to three-fourths their length are known as three-fourth bats.

Simple Staining Technique

4.2K
OverviewStaining techniques in microscopy enhance the visualization of microorganisms by increasing contrast and allowing the differentiation of cellular structures. Simple staining is one of the fundamental methods used to observe the basic morphological characteristics of microorganisms, including their size, shape, and arrangement. This method relies on the application of a single dye to stain the entire cell, producing a clear contrast between the cell and the background.FixationFixation is...

Differential Staining Technique01:26

Differential Staining Technique

2.5K
Differential staining is an essential microbiological technique that exploits variations in cell wall structures to classify and identify microorganisms. It facilitates the distinction of bacteria, aiding in diagnostic and research applications. Two of the most widely used differential staining methods are Gram staining and acid-fast staining, both of which rely on the chemical and structural differences in bacterial cell walls.Gram Staining TechniqueGram staining differentiates bacteria by...

Summary
This summary is machine-generated.

Dorsal preservation in rhinoplasty avoids midvault reconstruction and creates natural results. This technique, using push down or let down operations, is effective for selected primary cases.

Area of Science:

  • Plastic Surgery
  • Facial Plastic Surgery
  • Rhinoplasty Techniques

Background:

  • Nasal dorsum reduction in rhinoplasty often necessitates reconstruction of the keystone area.
  • Spreader grafts or flaps are commonly used to address aesthetic and functional deficits post-reduction.

Purpose of the Study:

  • To present a dorsal preservation technique in reduction rhinoplasty.
  • To evaluate the outcomes of this technique in a large clinical series.

Main Methods:

  • An endonasal approach was used.
  • A subdorsal septal strip was removed, followed by complete osteotomies.
  • Dorsal reduction was performed using either push down operation (PDO) or let down operation (LDO) based on hump size.

Main Results:

  • 320 patients underwent dorsal preservation operation (DPO) with no postoperative dorsal irregularities or inverted-V deformities.
  • Revision cases (8.74%) with prior DPO primarily required tip revisions, with few needing dorsal correction.

Conclusions:

  • Dorsal preservation techniques, including PDO/LDO, are effective and justified for selected primary rhinoplasty patients.
  • This approach yields natural dorsal lines, avoids midvault reconstruction, and is efficient for surgeons.
