The microscopic structure of paper: Micrograph of paper autofluorescing under ultraviolet illumination. The individual fibres in this sample are around 10 µm in diameter. There are three main chemical pulping processes. The sulfite process dates back to the 1840s‚ and it was the dominant process before the second world war. The kraft process‚ invented in the 1870s and first

GREEN PRACTICES IN RETAIL SECTOR Half a decade ago‚ environmentalists and experts predicted that the future will be green. This prediction has started becoming a reality. Retailers across global economies are carving a niche for themselves by adopting eco-friendly practices and producing products that are environment friendly. Today‚ everyone is concerned about preventing environmental degradation. Retailers have sensed the need for green retailing and now most of the Indian retailers are stepping

Management of XY | Modify diet (high fibre diet) will be provided.Basically we target only on breakfast and afternoon tea.This is because the fibre food sources during afternoon tea and breakfast is limited. Besides‚ we find that there are leftover especially vegetables during lunch and dinner. Hence‚ we will come out with few recipe incorporating hidden fibre in the meal.Hence‚ comparison between current diet and modify diet (high fibre diet) on costing and fibre content will be presented. | Residents

evolved through the introduction of modern technology and knowledge on certain events. In modern times the perfect crime is almost impossible to commit as a direct result of hair fibres. In order to commit a perfect crime every hair fibre would have to be removed (Mr Sanchez‚ 2011). This essay explores the importance of hair fibres in forensic science and strives to grasp concepts of such a field. Aim The aim of this investigation was to closely examine three different hair types and reflect on the similarities

best describe DWDM (coarse wavelength division multiplexing) and DWDM (dense wavelength division multiplexing)‚ you must first understand how WDM (wavelength division multiplexing) operates. WDM is multiplexing several optical signals on a single fibre by using wavelengths which are essentially colours of the laser light; to transmit different signals ranging from 2.5Gbps to 40Gbps. The device that connects the signals together is a multiplexor‚ and the one that splits them apart on the other end

nuclear membrane disintegrates. Chromosomes join at points called chiasmata where crossing over takes place. Metaphase I The nuclear membrane completely disappears. Spindle fibres attach to the chromosome’s centromeres and homologous pairs move together and line up along the metaphase plate. Anaphase I Spindle fibres pull homologous chromosomes towards opposite poles of the cell. This separates the chromosomes into two haploid set. Telophase I The homologous chromosomes arrive at there

In this essay I will include information regarding: cell differentiation‚ the functions of various cell organelles‚ tissues and a comparison of different tissue types. Cellular differentiation is the process by which a less specialised cell becomes a more specialised cell type. Differentiation happens a number of times during the development of a multicellular organism as
