ATP & Energy Systems

  • ATP (Adenosine Triphosphate) – Molecule that provides energy for muscle contractions. Limited storage.

  • Aerobic – With oxygen.

  • Anaerobic – Without oxygen.

Three Main Energy Systems

  1. ATP–PCr System (Anaerobic)

    • Duration: ~5 sec or less.

    • Very high intensity.

    • Uses stored creatine phosphate (CP).

    • Recharges ATP without oxygen.

  2. Glycolysis System (Anaerobic)

    • Duration: 30 sec–3

PRODUCTION CALCULATIONS

Production Capacity: 200 bars/minute = 12,000 bars/hour = 3,000 lbs/hour Daily Production Formulas:

  • Weekdays only: 5 days × 8 hours × 12,000 bars/hour
  • Weekdays + Saturday: 6 days × 8 hours × 12,000 bars/hour
  • Full week: 7 days × 8 hours × 12,000 bars/hour Monthly Production: Working days × daily capacity

MRP Inventory Formula: On Hand = Previous On Hand + Scheduled Receipts - Gross Requirements Place Planned Orders considering lead time (e.g., 2-week lead

Nervous system

The nervous system is the body's communication network, a complex system of nerves and cells (neurons) that carry signals to and from the brain and spinal cord to different parts of the body. It is divided into two main parts: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
Structure and Types of Neurons
Neurons are the fundamental building blocks of the nervous system. They are specialized cells that transmit electrical and chemical signals. While they can vary in size and...

Micro

Analytical techniques are methods used to identify, quantify, and understand the chemical composition and structure of substances. These techniques are broadly classified into qualitative (what is present) and quantitative (how much is present) methods. Common analytical techniques include:

1. Gravimetric Analysis

Involves measuring the mass of a substance to determine the amount of analyte.

Titrimetric (Volumetric) Analysis

Based on measuring the volume of a standard solution required to react...

🔧 1. Software Maintenance & Evolution

Q1: Explain the four types of software maintenance with examples.
There are four primary types of software maintenance: Corrective, Adaptive, Perfective, and Preventive. Corrective maintenance focuses on fixing errors or bugs in the software, such as patching a login failure. Adaptive maintenance involves updating the software to accommodate changes in the environment, like upgrading compatibility for a new operating system. Perfective maintenance enhances...
