Cognitive Psychology and Neuroscience: Core Concepts
Multitasking and Cognitive Performance
Performance decreases when doing multiple tasks simultaneously. Practice can improve performance but does not eliminate costs. Task switching incurs costs, specifically the time required to reconfigure the mental set. The multiple demand system is a network of brain regions activated during diverse cognitive tasks.
Feature Integration Theory
Early processing involves features (color, shape) detected automatically in parallel. Later processing requires features

1. Communicative Language Teaching (CLT)
CLT is an approach based on the idea that language is primarily used for communication. The objective is to develop communicative competence, which includes grammatical, sociolinguistic, discourse, and strategic competence. It is student-centered and promotes interaction, authentic materials, and real-life communication.
CLT helps learners communicate in real-life situations.
2. Principles of CLT
Students learn better when they use language actively and meaningfully.

Antitubercular Drugs: Treatment Regimens and DOTS Strategy
Antitubercular Drugs: Treatment and Classification
Antitubercular drugs are medications used to treat tuberculosis (TB) caused by Mycobacterium tuberculosis. These drugs are categorized into first-line and second-line treatments.
First-Line Antitubercular Drugs
First-line drugs are the most effective and are routinely used for all new TB cases. They include:
- Isoniazid (H)
- Rifampicin (R)
- Pyrazinamide (Z)
- Ethambutol (E)
- Streptomycin (S)
Second-Line Antitubercular Drugs
Second-line drugs are utilized for multidrug-

1. Partial Differential Equations and Probability
(a) Solve the PDE (D² − 3DDʹ)z = 0
The auxiliary equation is obtained by replacing D with m and Dʹ with 1:
m² − 3m = 0 ⇒ m(m − 3) = 0 ⇒ m = 0, 3
Solution: z = f₁(y) + f₂(y + 3x)
(b) Classify the PDE: 4∂²u/∂x² − 4∂²u/∂x∂t + ∂²u/∂t² = 0
Comparing with A·u_xx + B·u_xt + C·u_tt = 0: A = 4, B = −4, C = 1
Discriminant = B² − 4AC = 16 − 16 = 0
Since B² − 4AC = 0, the equation is Parabolic.

Characteristics of the UK Constitution
- Unwritten Nature: Unlike most modern states, the UK does not have a single codified document. It consists of statutes, common law, conventions, and historical documents like the Magna Carta.
- Sovereignty of Parliament: Parliament is the supreme legal authority, which can create or end any law.
- Unitary State: Power is concentrated in the central government, though some powers are devolved to Scotland, Wales, and Northern Ireland.

Java Shipping Logic and Software Architecture
Shipping Cost Calculation Logic
The following rules define the shipping cost based on weight:
- Return -1 if the weight is less than 0 or greater than 100 kg.
- Return 10.00 if the weight is between 0 and 10 kg.
- Return 20.00 if the weight is between 10.01 and 20 kg.
- Return 50.00 if the weight is between 20.01 and 50 kg.
- Return 100.00 if the weight is between 50.01 and 100 kg.

Correlation Definition
Correlation measures the strength and direction of a relationship between two variables.
Warning: Correlation does NOT imply causation.
Types of Correlation
| Type | Description | Graph Trend |
|---|---|---|
| Positive Correlation | Variables increase/decrease together | Upward slope |
| Negative Correlation | One increases while the other decreases | Downward slope |
| Zero Correlation | No predictable relationship | Random |
Concrete Durability, Testing, and Structural Failure Analysis
UNIT-01
Q.1&2. Brief about the physical deterioration of concrete.
Ans:-
- 1) Physical deterioration of concrete refers to the damage or reduction in strength of concrete due to physical actions such as temperature changes, abrasion, erosion, and moisture variation. It affects the durability and service life of structures.
- 2) Freeze-thaw action is one of the major causes of deterioration in cold regions. Water inside concrete pores freezes and expands, causing cracks and surface scaling.
- 3) Abrasion
