Natural materials come from living things or the ground and include cotton, wood, feathers, wool, leather, slate and crude oil. Manufactured materials are made by people by transforming natural materials through processes like cutting down trees to make paper, shearing sheep to make fabric from wool, and refining crude oil to make plastic. These materials are then used to create various products.

La nutrición permite a las células obtener energÃa y materiales a través de la digestión, la respiración y la circulación. La digestión transforma los alimentos en nutrientes a través del aparato digestivo. La respiración extrae oxÃgeno del aire mediante el aparato respiratorio. La circulación transporta los nutrientes y el oxÃgeno a las células y recoge desechos a través del aparato circulatorio.Carnivores herbivores omnivores_KAH

The document discusses what different types of animals eat. It explains that carnivores, like foxes and lions, eat other animals. Herbivores, such as sheep and giraffes, eat only plants. Omnivores, including humans, bears and pigs, eat both plants and other animals. Most people are omnivores that obtain food from both plant and animal sources. The document provides examples of carnivores, herbivores and omnivores and encourages remembering that some human food comes from plants and some from animals.Andalucia Presentation

The document discusses manufacturing industries in India. It begins by defining manufacturing as the production of goods through processing of raw materials. It then explains that the manufacturing sector is important for job creation, reducing unemployment and poverty, and contributing to exports and foreign exchange. However, India's manufacturing share of GDP is only 17%, lower than some East Asian countries. The document also covers different types of industries classified by raw materials (agro-based, mineral-based) and ownership (public, private, joint), and provides examples like cotton, steel, aluminum, and automobile industries. It concludes by discussing environmental pollution caused by industries and some measures to control degradation.U7. tertiary sector

Manufacturing industries convert raw materials into finished goods using machines. They are important for a country's economic strength by providing jobs, reducing dependence on agriculture, and earning foreign exchange through exports. Key manufacturing industries in India include cotton textiles, jute, wool, silk, synthetic fibers, sugar, and iron and steel. Factors like availability of raw materials, power, water, labor, transportation and markets influence the location of these industries. The cotton textile industry is the largest, with mills located mainly in Maharashtra, Gujarat and West Bengal. The iron and steel industry began in 1830 in Tamil Nadu and large-scale production started in Jamshedpur in 1907.How to Become a Thought Leader in Your Niche

Validity is an important characteristic of a test. A test having low validity is of little use. Validity is the accuracy with which a test measures whatever it is supposed to measure. Validity can be low, moderate or high. There are many factors which affect the validity of a test. If these factors are controlled, then the validity of the test can be maintained to a high level. In the power point presentation, factors affecting validity are discussed with the help of concrete examples.Blind spots in AI and Formulation Science, IFPAC 2025.pdf

Ìý
The intersection of AI and pharmaceutical formulation science highlights significant blind spots—systemic gaps in pharmaceutical development, regulatory oversight, quality assurance, and the ethical use of AI—that could jeopardize patient safety and undermine public trust. To move forward effectively, we must address these normalized blind spots, which may arise from outdated assumptions, errors, gaps in previous knowledge, and biases in language or regulatory inertia. This is essential to ensure that AI and formulation science are developed as tools for patient-centered and ethical healthcare.
