Obedience01:08

Obedience

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation, obedience...
Interference and Diffraction02:18

Interference and Diffraction

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.
Ethical Dilemmas I01:17

Ethical Dilemmas I

Ethical dilemmas in nursing are of utmost importance, as they often arise from the tension between adhering to core ethical principles and the practical realities of healthcare delivery. These dilemmas require nurses to navigate complex situations where competing ethical considerations pull them in different directions.
Let us explore some examples to understand the potentially complex moral decisions nurses face.
Take the case of caring for minors, particularly in areas related to reproductive...
Nurses' Legal Responsibilities III01:16

Nurses' Legal Responsibilities III

Nurse-to-nurse relationships are legally required to adhere to professional standards, ensuring a respectful and positive working environment. Professional conduct demands that nurses treat all colleagues respectfully and courteously, fostering a productive, supportive workplace. Nurses must actively eliminate bullying, discrimination, and harassment to maintain a safe and inclusive environment.
Cultivating a culture of collaboration and mutual respect among nurses transcends mere enhancement...
Introduction to force01:25

Introduction to force

Consider water flowing from a nozzle to a turbine vane. As the water hits the turbine vane, it exerts a force that causes it to move along the flow of direction. Force is an impact that changes an object's motion, shape, or orientation. Forces can be caused by physical contact, such as a push or pull, or through non-contact interactions, such as magnetic or gravitational forces. Force is a vector quantity with both magnitude and direction, and is measured in newtons (N) in the SI unit system.
Interference: Path Lengths01:10

Interference: Path Lengths

Consider two sources of sound, that may or may not be in phase, emitting waves at a single frequency, and consider the frequencies to be the same.
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

  • 細胞生物学 細胞生物学
  • 分子生物学は分子生物学である.

背景:

  • メイオシスは性繁殖の根本的なプロセスである.
  • クロスオーバー,または遺伝的再結合は,遺伝的多様性を確保します.
  • 染色体ペアあたりのクロスオーバーの数は厳格に規制されています.

研究 の 目的:

  • 交差の開始と,微分化の過程における交差の最終的な数との関係を調査する.
  • クロスオーバー周波数を制御するメカニズムを理解する.

主な方法:

  • Martini et al.による研究によると, (2006年) は,交配期中のクロスオーバーコントロールを分析することに焦点を当てました.
  • 具体的な方法は,クロスオーバーを誘発するイベントとその下流の影響を調査することでした.

主要な成果:
