The main source of elevated fluoride in plants comes from atmospheric industrial pollution.
Because of its extensive industrial use, hydrogen fluoride is probably the greatest single atmospheric fluoride contaminant and is generally considered to be the most important plant pathogenic fluoride (WHO, 1984; Treshow, 1965)…
When you have decided what stage of the Introduction they belong to, refer to the stages in a thesis introduction and give each sentence extract a number.
Then check the suggested answer to see if your answer agrees with ours.
This question has not been resolved due to the inability to accurately localize low concentrations of fluoride(Doley, 1986a)Knowledge of the effects of fluoride on the reproductive processes of species within a forest community will help predict potential changes within the community following an increase in atmospheric fluoride due to additional industrial sources, such as aluminium smelters.
For these reasons, this project was designed to investigate the reproductive processes of selected species in a woodland near the aluminium smelter at Tomago.Most thesis introductions include SOME (but not all) of the stages listed below.There are variations between different Schools and between different theses, depending on the purpose of the thesis....However, fluorides can cause damage to sensitive plant species even at extremely low fluoride concentrations(Hill,1969), accumulate in large amounts within the plant and cause disease if ingested by herbivores(Weinstein, 1977).Doley (1981) summarized several unpublished studies that compared the sensitivity rankings of 24 species according to the responses of photosynthesis and the development of visible injury symptoms.This study investigates the effects of ten years of increased atmospheric fluoride from Tomago Aluminium Smelter, New South Wales on the reproductive processes of three selected native species, Banksia aemula, Bossiaea heterophylla and Actinotus helianthi…The study aims to determine the effects of the fluoride emissions on the reproductive processes of the selected species by analyzing the differences between several of their reproductive and associated characteristics found along a fluoride gradient.Currently in the PV industry aluminium-silicon alloying using screen-printed aluminium and belt furnace firing is the prevalent method of forming p-type layers because it is relatively easy and also forms the rear electrical contact…...The goal of this thesis is to evaluate boron nitride (BN) as a potential replacement for liquid-source diffusion presently being used for p-type diffusions in the high-efficiency buried contact solar cells under development at UNSW……This thesis is divided into five chapters: Chapter 2 discusses in more detail about diffusions in general and the case of boron diffusion…Chapter 3 outlines the experimental work carried out in the project……Quasispecies are defined as a population of closely related minor genetic variants and are a noted phenomenon of plant and RNA viruses…It has been widely recognised that treatment outcome is highly dependent on the complexity……There is mounting evidence, however, that immediate treatment will result in successful eradication of HCV.Furthermore, a rapid and simpler alternative method to cloning and sequencing can be developed to accurately describe the complexity of a given quasispecies population…Read the following sample sentence extracts from Honours theses Introductions.
