Name: Leung Chun Wai Student no.: G20554292 Topic: (NT3048) Smoke extraction design for large space such as atrium 1. INTRODUCTION Atrium inside a building is an old architectural concept for about two thousand years. This concept has been developed and extended to modern buildings. Current trend of atrium design provides an ‘ideal’ external environment to the occupants with a large undivided space. The major problem for fires in atrium is hot and toxic gases accumulating and go down in the atrium

DNA EXTRACTION In extracting chromatin from the cells of wheat germ there are seven steps to follow. The optimal cell to use would be the polyploidal eukaryotic. Eukaryotes have nucleus membrane-bound organelles‚ while prokaryotic does not. The polyploidal eukaryotic cell has DNA that is held in the nucleus while the prokaryote has DNA that floats freely around the cell. The DNA of eukaryotes is more complex and extensive than the other. Prokaryote is a bacterial cell that

Objective: To extract caffeine from tea powder using polar - nonpolar solvent extraction technique. Theory: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves

A seed is an embryonic plant that is enclosed in a seed coat or some kind of protection (Seed‚ 2009). A seed is the basis for any plant life; it is the essential beginning for any sort of growth. A seed is created from a previous plant or two plants pollinating with each other to create a seedling (Seed‚ 2009). Typically there are three main parts of a seed: an embryo‚ nutrients for the embryo‚ and a seed coat (Seed‚ 2009). The embryo is the true essential of the seed. It contains the one cotyledon

The Effects of a Seed Coat in Seed Germination Mario Monroe INT1 Task 3 The Effects of a Seed Coat in Seed Germination Abstract Seed germination is an important aspect in plants growth and food production. It is therefore it’s of uttermost importance to know the effective ways of seed germination so as to improve food production. This research was therefore prompted by the rising issue of farmers buying low quality and a damaged maize seed from unscrupulous sellers and this has led to deterioration

The Difference Between Onion Red Rum Bunching Seeds Germinating at 70 degrees compared to 40 degrees. Abstract Researchers tested the germination of Red Rum Bunching Seeds in different temperatures. Research shows that depending on the seed germination is most likely to occur at a higher temperature rather than a colder one. According to the results the germination rate for seeds at room temperature was 96% compared to seeds in the fridge which germinated at 0% Review of Literature According
