1. Shape Memory Alloys (SMAs)
Definition
Shape Memory Alloys R metallic materials that can recover their original shape after deformation when exposed 2 a specific stimulus, usually heat.
The most common example is Nickel-Titanium (Nitinol), known 4 its shape memory & superelastic behavior.
Mechanism
a. Phase Transformation
SMAs operate through a solid-state transformation between 2 phases:
Explain array implementation of list. 5 marks
An array implementation of a list involves using a contiguous block of memory to store elements, allowing for efficient access and manipulation. Here’s a breakdown of the key aspects of this implementation:
1.) Structure:
°An array is a fixed-size data structure that holds elements of the same type. In the context of a list, an array can be used to store the list elements in sequential memory locations.
°The size of the array is typically defined
Define ADT. Explain array as an ADT? (2+3 marks)
An Abstract Data Type (ADT) is a conceptual model that defines a set of operations and behaviors for a data structure, without specifying the underlying implementation details. Arrays, as an ADT, define how data is organized and accessed through indices, but not how it's actually stored in memory.
Arrays as an ADT
-An array ADT defines a collection of elements that can be accessed by their index (position).
-Common operations on an array ADT

# define management ? what kinds of skills required for successful manager ?
Management is basically about getting things done through people.

Good management keeps everything running smoothly and helps everyone work toward the same vision.
Skills Every Successful Manager Needs:
1. Leadership : A great manager leads
Understand the basic concepts and equations of radiometric dating, the difference between parent and daughter atoms, half-life, and decay constant. (n_e: number of planets, per star, with suitable environment for life)
Asthma Definition— Asthma is a condition in which our airways become narrow, swell up and become more glandular (produce extra mucus).
Classification of Asthma— Seasonal asthma—Some of the people not tolerate even the minute changes in the season (cold, hot, rain). Due to seasonal variation allergic reaction also occurs, and leads to complicated if not treated during the starting conditions. Allergic asthma—Allergens (pollen, animal dander, dust etc.) Occupational asthma—In
General Microbiology
Prokaryotic vs Eukaryotic:
Prokaryotic: no nucleus (Bacteria, Archaea)
Eukaryotic: has nucleus (Protists, Fungi, Plants, Animals)
Unicellular vs Multicellular: Bacteria and Protists = one cell; Fungi = one or many cells; Plants and Animals = many cells
How they eat:
Autotroph = makes its own food (like plants)
Heterotroph = eats other things (like animals)
Decomposer = breaks down dead stuff (like fungi)
Key Discoveries: Microscopes helped find microbes,
