Progressive Muscle Relaxation: A Path to Stress Relief and Well-being

Progressive Muscle Relaxation (PMR) is a widely recognized technique developed in the early 1920s by American physician Edmund Jacobson. Rooted in the idea that physical relaxation leads to mental calmness, PMR is a method that involves systematically tensing and then relaxing different muscle groups in the body. This practice helps individuals become more aware of physical tension and learn how to release it, promoting overall...

FULL SUMMARY

1. Vision, Mission and Values (Collins & Porras, 1996)

  • Vision describes a desirable long-term future (includes BHAG + vivid description).

  • Mission defines the organization's purpose; Values outline guiding principles.

  • These components form a "core ideology", providing stability in turbulent environments and direction for change.

  • Despite potential, many statements are met with cynicism due to misalignment between rhetoric and reality.

  • Statements should not be PR-driven;

a) Atomicity: Ensures a transaction is all-or-nothing. Durability: Guarantees committed data remains after a crash.b) Redundancy in a schema refers to unnecessary duplication of data.c) Cascading rollback occurs when the failure of one transaction causes others to roll back.d) External storage in DBMS refers to storage devices like hard drives or SSDs used to store large data files.e) ACID properties: Atomicity, Consistency, Isolation, Durability.f) A heap file is an unordered collection of records

a) A transaction is a sequence of operations performed as a single logical unit of work, ensuring consistency, atomicity, isolation, and durability (ACID).b) Primary index is based on the primary key and is ordered; secondary index is created on non-primary key attributes and may not be ordered.c) Functional Dependency means attribute Y is functionally dependent on X if each value of X is associated with exactly one value of Y (X → Y)d) Concurrency control ensures that database transactions are

Here's a clear and structured comparison and explanation of PN junction diode and Zener diode, two fundamental semiconductor devices:


🔹 PN Junction Diode

Definition:

A PN junction diode is a semiconductor device formed by joining P-type and N-type materials. It allows current to flow only in one direction — from the anode (P-side) to the cathode (N-side).

⚙️ Working Principle:

  • Forward Bias: When P-side is connected to the positive terminal of a battery and N-side to the negative

in a database management system (DBMS), allowing transactions to run concurrently has significant advantages, such as better system resource utilization and higher throughput. However, it is crucial that these transactions do not conflict with each other. The ultimate goal is to ensure that the database remains consistent and accurate. For instance, if two users try to book the last available seat on a flight at the same time, the system must ensure that only one booking succeeds. Concurrency control...
