Public Health Fundamentals: Wellness, SDOH, and Policy Impacts
Defining and Achieving Wellness
Wellness is the process by which health is achieved, involving choices that we make to improve or maintain health, or more broadly, improve our existence. Wellness, like health, exists across various dimensions.
Dr. Bill Hettler’s Six Dimensions of Wellness
- Intellectual:
- Expanding knowledge, engaging in creative and stimulating activities.
- Physical:
- Self-care and health-enriching behaviors.
- Spiritual:
- Appreciation for life and natural forces in the universe.
- Emotional:
- Awareness
Prospectus, Share Types and Share Capital Regulations
Prospectus
A prospectus is a legal document issued by a public company inviting public subscriptions for shares or debentures, containing detailed disclosures on company objectives, financials, risks, management, and capital structure per SEBI (ICDR) Regulations and Companies Act, Section 26 [from previous]. It ensures investor protection through mandatory information such as material contracts, litigation, and promoter details; shelf/deemed prospectuses apply for follow-on offers [from previous]
Digital Number Systems: Binary, Hexadecimal, and BCD
Understanding Number Systems
Number systems are fundamental to computing and digital electronics. They are essentially methods for representing numbers using a specific set of symbols (digits). The key concept differentiating them is the base or radix, which is the total number of unique digits available in that system.
Common Number Systems Breakdown
1. Decimal (Base-10)
This is the number system we use every day.
- Base (Radix): 10
- Digits Used: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
- Concept: Each digit’s position
Cinematic Contrast: Loneliness and the Male Gaze in Her and Lambs
Representing Isolation: Her vs. The Silence of the Lambs
Spike Jonze’s Her (2013) and Jonathan Demme’s The Silence of the Lambs (1991) both examine characters who experience deep loneliness, but they show this isolation using very different visual strategies. Her uses warm colors, soft lighting, and close-up shots to reveal Theodore’s emotional isolation and his sometimes idealized or unrealistic view of the women around him. In contrast, The Silence of the Lambs relies on point-of-view shots,

The Iterative Design Process
The iterative design process is one of the most traditional processes for the design of any engineering component or system. It is used widely throughout many industries. The process is not very efficient! With the advent of more streamlined digital workflows, we aim to cut out excess iterations from our process. The majority of your projects will likely follow this process.

Modern Architectural Theory and Its Evolution
Adolf Loos: Ornament and Modernity
Adolf Loos’s argument that “ornament is a crime” is one of the most radical rejections of traditional aesthetics in architectural history. In his 1908 essay Ornament and Crime, Loos positions ornament not only as culturally outdated but morally and economically harmful. He associates decorative design with primitivism, degeneracy, and even criminality—claiming that modern man has evolved beyond the need for surface embellishment. This stance is both bold

Arbitrary Code Execution (ACE)
Arbitrary Code Execution (ACE): A vulnerability where an attacker supplies input to a program such that the CPU interprets that input as executable instructions and runs it. The CPU cannot distinguish between legitimate program code and malicious injected code. Once ACE happens, the attacker controls instruction flow; security boundaries are effectively gone and the system executes whatever the attacker wants.
Buffer Overflow (BO)
BO (Buffer Overflow): All buffer overflows

Negotiable Instruments Act, 1881
The Negotiable Instruments Act, 1881 is the foundational law in India that defines and amends the law relating to promissory notes, bills of exchange, and cheques.
Scope and Features of Negotiable Instruments
Scope
The Act deals primarily with three specific types of instruments (Section 13):
- Promissory Note (Sec. 4)
- Bill of Exchange (Sec. 5)
- Cheque (Sec. 6)
The Act also covers concepts such as maturity, negotiation, endorsement, crossing, presentment, notice of dishonour,
Read MoreMechanisms of Synaptic Transmission and Plasticity
The Process of Synaptic Transmission
The action potential signal arrives at the axon terminal (the bouton). The local depolarization causes Ca channels to open. (Is this channel voltage, chemically, or mechanically gated? Voltage). Ca enters the presynaptic cell because its concentration is greater outside the cell than inside. The Ca, by binding with calmodulin, causes vesicles filled with neurotransmitter to migrate towards the presynaptic membrane.
Neurotransmitter Release and Exocytosis
The vesicle

Social Media and Mental Health Outcomes
The relationship between social media and mental health is complex, characterized by mixed outcomes. Use is linked to both positive factors, such as connection and identity, and negative factors, including depression and anxiety.
- Small effect sizes: The overall impact depends on specific behaviors, content, and individual traits.
- U-shaped curve: A relationship where both extremely high and extremely low use correlate with worse mental health, while moderate use
