RTB eLearning

Fisheries and aquaculture. It is intended to the learners pursuing TVET Certificate

V in Animal health. Upon completion of this module the learners will be able to

Install aquaculture system, assist in hatching operations, perform nursery

activities, grow and harvest fishes.

This module covers the knowledge; skills and attitudes required to provide a balanced feeding to domestic animals by managing fodder crops and pasture in an optimum manner. It is intended for learners who have successfully completed ordinary level, level II in animal health or its equivalent and pursuing TVET level III and related qualification. Upon completion of this module, the trainee will be able to: Cultivate fodder crops, perform pastures lay out and improvement and Manage pasture grazing

This module describes the skills, knowledge and attitudes required to identify history of food processing industry, identify food safety requirements and describe important processing operations in the food industry. At the end of this module, participants will be able to identify most important historical events of the transformation of cooked ingredients, by physical or chemical means into food, or of food into other forms. Learners will be able to improve food safety-related behaviours and practices. They can describe food processing activities such as mincing and macerating, liquefaction, emulsification, and cooking, pickling, pasteurization, and many other kinds of preservation and canning or other packaging.

Forging is a metalworking process in which a piece of metal is shaped into the desired form by applying compressive forces, usually delivered through a hammer, press, or die. The operation is carried out while the metal is either hot (hot forging) or cold (cold forging), depending on the material and application.

Forging is a metalworking process where compressive forces are applied to shape metal, typically using a hammer or press. It improves mechanical properties by aligning the grain structure.

🔹 Purpose:

• To produce strong, durable parts
• Used in high-stress applications (e.g., automotive, aerospace, tools)

🔹 Types of Forging:

1. Open-Die Forging
• Workpiece is compressed between flat dies
• Suitable for large or simple shapes
2. Closed-Die Forging (Impression Die)
• Metal is compressed in a die cavity
• High precision and complex shapes
3. Cold Forging
• Performed at room temperature
• Better surface finish, high dimensional accuracy
4. Hot Forging
• Done above recrystallization temperature
• Easier to shape, less stress on equipment

🔹 Materials Used:

• Steel (carbon, alloy, stainless)
• Aluminum
• Titanium
• Brass and copper

Modern frontend development often revolves around React.js, a JavaScript library for building dynamic, component-based user interfaces. React allows developers to create reusable components, manage application state, and update the UI efficiently through its virtual DOM. Its declarative approach, powered by JSX and hooks like useState and useEffect, makes building interactive web applications both scalable and maintainable.

On top of React, developers often use Next.js, a React-based framework that enhances the development experience by offering features like server-side rendering (SSR), static site generation (SSG), API routes, and built-in routing. This makes Next.js particularly valuable for performance optimization and search engine optimization (SEO), areas where plain React applications can fall short.

For styling, Tailwind CSS has become a popular choice. Unlike traditional CSS, Tailwind is a utility-first framework that provides low-level utility classes, enabling developers to build custom designs directly in the markup. Its approach speeds up development, ensures design consistency, and integrates seamlessly with React and Next.js.

While Next.js has its own routing system, projects built with plain React often rely on React Router, a widely used library for handling navigation in single-page applications. It enables developers to define routes, handle nested navigation, and manage dynamic parameters, creating a smooth user experience without full page reloads.

To add type safety, TypeScript is frequently paired with React and Next.js. TypeScript introduces static typing to JavaScript, helping developers catch errors at compile time, improve code readability, and make applications more robust. With TypeScript, components can define the shape of props, states, and return values, making large-scale applications easier to manage.

Bringing these tools together results in a modern React application workflow. React provides the foundation for building UI, Next.js adds advanced rendering and routing capabilities, Tailwind streamlines styling, React Router supports SPA navigation (when used outside Next.js), and TypeScript ensures type safety and maintainability. This combination empowers developers to build fast, responsive, scalable, and developer-friendly frontend applications.
