Human Nutrition

Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. Poor nutrition is a chronic problem often linked with poverty, food security, or a poor understanding of nutrition and dietary practices and poor knowledge about nutrients required by the body at various stages of life to prevent deficiency of nutrients which can have adverse effects on the body. Malnutrition and its consequences are large contributors to deaths, physical deformities, and disabilities worldwide. Good nutrition is necessary for children to grow physically and mentally, and for normal human biological development.


The human body contains chemical compounds such as water, carbohydrates, amino acids (found in proteins), fatty acids (found in lipids), and nucleic acids (DNA and RNA). These compounds are composed of elements such as carbon, hydrogen, oxygen, nitrogen, and phosphorus. Any study done to determine nutritional status must take into account the state of the body before and after experiments, as well as the chemical composition of the whole diet and of all the materials excreted and eliminated from the body (including urine and stool).

The seven major classes of nutrients are carbohydrates, fats, fiber, minerals, proteins, vitamins, and water. These nutrients can be grouped as macronutrients (needed in large quantities) and micronutrients (needed in small quantities). Carbohydrates, fats, and proteins are macronutrients, and provide energy. Water and fiber are macronutrients but do not provide energy. The micronutrients are vitamins and minerals.

Joint Meetings of the Australian Parliament

 A joint meeting of the Australian Parliament is a convening of members of the Senate and House of Representatives sitting together as a single legislative body. Australia has a bicameral federal Parliament, consisting of the Senate and House of Representatives. Subject to the Constitution of Australia, each House has its own rules, standing orders and procedures, its own presiding officer, and meets separately, at dates and times it alone decides. However, there are some occasions when the two Houses have come together as a single body. Unlike the Opening of Parliament which is officially made by the Governor-General at the Senate premises, the joint sessions are held at the House of Representatives chamber. The reasons of joint meetings have included: To resolve deadlocks between the Houses following the trigger of a double dissolution To fill casual vacancies in the representation of the territories in the Senate A special commemorative joint sitting to Celebrate the Centenary of Fe

Our Lady of Peace and Good Voyage

 Our Lady of Peace and Good Voyage or the Virgin of Antipolo is a seventeenth century Roman Catholic wooden image of the Blessed Virgin Mary as venerated in the Philippines. This Black Madonna is enshrined in Antipolo Cathedral in the Sierra Madre mountains east of Metro Manila. The image was brought to the country by Governor-General Juan Niño de Tabora from Mexico via the galleon El Almirante  in 1626. His safe voyage across the Pacific Ocean was attributed to the image, which was then given the title "Our Lady of Peace and Good Voyage." It was substantiated later by six other successful voyages of the Manila-Acapulco Galleons witb the image aboard as its patroness. Pope Pius XI issued a Pontifical decree to crown the image in 1925. The statue is one of the most celebrated Marian images in the Philippines, having mentioned by national martyr Jose Rizal in his writings. From May to July each year, the image attracts millions of pilgrims from all over the country and abroad.

How to Create a Richly Imagined World

For someone who likes fantasy and sci-fi fiction, most of the time, a lot of people ask me about how to create a richly imagined world. Fantasy and sci-fi elements rest heavily on how an author weave the setting and the world in which the heroes dwell in, and it helps to make the novel to be imagined vividly in the readers' minds. A convincing world should be relatable, something that we can associate ourselves with. For us to be associated with a world an author created in his mind, and wrote on the pages of a book, this world has to be close to the real thing. It has to be systematic, real and alive, and very convincing. A real world has certain elements, and an author must consider them in writing a vividly imagined world: Cartography - a fantasy or sci-fi world depend heavily on geography and maps, especially if the plot requires war and the belligerents occupy so much space in the plot. A convincing world has the world separated in territories, and every part of the
