1. Nature and Scope of Accounting

Nature of Accounting

• Systematic Process: Identifying, recording, classifying, summarizing, and interpreting business transactions.
• Historical in Nature: Primarily records past events.
• Quantitative: Deals mostly with financial/monetary information.
• Dual Aspect: Based on the double-entry system (debit equals credit).
• Communication Tool: Provides information to stakeholders.

Scope of Accounting

• Financial Accounting: Recording and reporting of transactions (Profit & Loss, Balance Sheet).
• Cost Accounting: Ascertainment of cost, cost control, and decision-making.
• Management Accounting: Provides financial and non-financial information for planning and control.
• Tax Accounting: Deals with income tax, GST, and compliance.
• Auditing:

Levels of Biological Organization

• Atom
• Molecule
• Cell Organelles
• Cell
• Tissue
• Organ
• Organ System
• Organism

• Ecosystem
• Biome

Connective Tissue Fundamentals

Function of Connective Tissue

Connective tissues serve to bind structures, support, protect, and fill in gaps (filler).

Characteristics of Connective Tissues

Connective tissues are characterized by:

• Cells residing inside an Extracellular Matrix (ECM).
• The ECM includes fibers and ground substance.
• The tissue is typically vascular (contains blood vessels).

General Cell Types of Connective Tissue

• Fibroblast/Fibrocyte: Fixed cells that produce matrix fibers.
• Macrophages: Wandering cells that remove dead and foreign particles.
• Mast Cells: Located near blood vessels; they prevent

Demineralization of Brackish Water by Electrodialysis

This detailed explanation covers the process of demineralization of brackish water using Electrodialysis (ED), based on standard water chemistry concepts.

Brackish Water Characteristics

Brackish water contains dissolved salts, with salinity levels higher than freshwater but lower than seawater. It tastes salty and is generally unsuitable for drinking or industrial use. To make it potable, salts must be removed (desalination).

Electrodialysis Principle

Electrodialysis is an electrochemical desalination process. When an electric field is applied, ions (salts) in the water migrate through specialized ion-selective membranes:

• Cation-exchange membranes: Allow only cations (e.g., Na⁺, Ca²⁺, Mg²⁺)

Understanding the Term "Inter Galvanic Current"

The term Inter galvanic current is not standard or widely recognized in medical, scientific, or engineering contexts. It likely refers to one of the following concepts, based on how the term might be interpreted:

1. Galvanic Current in Electrotherapy and Cosmetology

Galvanic current is a Direct Current (DC) used primarily in medical and cosmetic treatments, particularly in electrotherapy. It is continuous, unidirectional, and typically used to:

• Stimulate blood circulation.
• Promote tissue healing.
• Perform iontophoresis (driving medications or ions through the skin).
• Treat muscle atrophy or improve muscle tone.
• Used in facial treatments for deep cleansing (desincrustation) and product penetration (iontophoresis)

A bed sore, also known as a pressure ulcer or decubitus ulcer, is an area of damaged skin and tissue that develops when prolonged pressure cuts off circulation to particular parts of the body, especially over bony areas. Without enough blood flow, the affected tissue dies. Understanding the causes, prevention, and management of these injuries is crucial for patient care.

Definition of Pressure Ulcers

A bed sore is a localized injury to the skin and/or underlying tissue, usually over a bony prominence, as a result of prolonged pressure, or pressure in combination with shear.

Common Sites for Pressure Ulcer Development

• Sacrum (lower back)
• Heels
• Hips
• Elbows
• Ankles
• Back of the head
• Shoulder blades

Stages of Bed Sores (Pressure Ulcers)

1. Stage 1: Red, unbroken

✅ Control of Haemorrhage (Bleeding)

Controlling haemorrhage involves stopping the bleeding, maintaining circulation, and preventing shock. The approach depends on the type and severity of the bleeding.

Types of Haemorrhage

1. External Haemorrhage: Visible bleeding from a wound.
2. Internal Haemorrhage: Bleeding inside the body.
3. Arterial Bleeding: Bright red, spurting blood.
4. Venous Bleeding: Dark red, steady flow of blood.
5. Capillary Bleeding: Oozing blood from capillaries.

Methods for Controlling Haemorrhage

Immediate Measures (First Aid)

• Direct Pressure: Apply firm pressure directly on the wound with a clean cloth or dressing.
• Elevation: Elevate the bleeding part above the heart level, if no fracture is suspected.
• Immobilization: Keep the injured part still

Physical Medicine & Rehabilitation Essentials

Physical Medicine and Rehabilitation (PM&R), also known as physiatry, is a medical specialty dedicated to enhancing and restoring functional ability, independence, and quality of life for individuals with physical impairments or disabilities. It adopts a holistic approach, focusing on the whole person rather than solely on the disease, by integrating medical treatment with physical, psychological, and social rehabilitation strategies.

Historical Roots of PM&R

PM&R began developing as a distinct specialty in the early 20th century. It gained prominence during and after World War I and II, when large numbers of injured soldiers required systematic rehabilitation to return to society....

Realistic Representation of Teen Identity in Literature

Ultimately, teen identity is realistically represented within the novel, highlighting the difficulties of navigating social circles as an adolescent and the struggles most people face.

Ponyboy Curtis: Navigating Identity and Social Cliques

The novel presents the complexities of teen identity by showing the struggles of Ponyboy as he navigates his relationships with Darry and the Greasers. From the beginning, Ponyboy is portrayed as an intelligent and sensitive, yet not particularly street-smart, teenager, making it challenging for him to fit in.

This inner conflict is highlighted in his first-person narration, particularly in a scene where he admits:

“I’m not like them. And nobody in our

Crutches: Mobility, Types, and Safe Use

Crutches are mobility aids designed to help individuals walk when they cannot use one or both legs effectively. They transfer weight from the legs to the upper body, allowing a person with an injury, surgery, weakness, or disability in the lower extremities to move around safely and independently. Crutches are commonly prescribed after fractures, ligament injuries, joint replacements, or neurological conditions that impair balance or strength.

Purpose and Function of Crutches

The main function of crutches is to provide support, balance, and mobility. They relieve pressure from an injured leg or foot by shifting body weight to the arms and shoulders. Crutches also help maintain independence during recovery,... Continue reading "Mobility Aids and Rehabilitation: Crutches, Splints, PMR" »

What Is Mobile Computing?

Mobile computing is a technology that allows the transmission of data, voice, and video through a computer or any other wireless-enabled device without being connected to a fixed physical link. It enables users to perform computing tasks anytime and anywhere using mobile devices such as smartphones, laptops, tablets, and PDAs connected through wireless networks.

Key Features of Mobile Computing

• Ubiquitous Access: Users can access services and information from any location.
• Wireless Communication: Relies on wireless networks like Wi-Fi, cellular (4G, 5G), and Bluetooth.
• Real-time Connectivity: Provides continuous connection to networks and services.
• Portability: Devices are designed to be lightweight and easily carried.
