The Later Years

He was forced to retire at age 70, but his passion for research, the desire to be close to former colleagues and young people kept him going regularly to the Institute of Pharmacy. He used to move around using a bicycle that he left each morning in the basement near the University Building entrance. 

His methodical precision made Passerini s ordinary day quite predictable at 7 P.M. he went home by bicycle. One evening, he was unaware that the access hutch to the cellar was open and he inadvertently fell down the stairs. It was a serious accident that compromised Passerini s health. He was hospitalized and, contraiy to all predictions, after a long period of hospitalization, he seemed to become fiilly recovered. Unfortunately, nothing might have presaged what would happen shortly thereafter. On 16 November 1962 at the age of 71, Mario Passerini, afliected by asymptomatic atherosclerosis, suffered an acute ischemic attack and died at his Florence home.

The declining-balance method of depreciation allows equipment or plant to be depreciated by a greater amount during the earlier years than during the later years. This method does not allow equipment or plant to be depreciated to a zero value at the end of the service life. 

In the sinking-fund method of depreciation, the effect of interest is to make the annual decrease of the book value of the equipment or plant less in the early than in the later years with consequent higher tax due in the earlier years when recovery of the capital is most important. 

Thus, cash flow in the early years of a project has a greater value than the same amount in the later years of a project. Therefore, it pays to receive money as soon as possible and to delay paying out money for as long as possible. 

An (NPV) or (DCFRR) estimation will be no better than the accuracy of the projec ted cash flows over the life of the project. Clearly, one is likely to predict cash flows more accurately for 2 or 3 years ahead than, say, for 9 or 10 years ahead. However, since the cash flows for the later years are discounted to a greater extent than the cash flows for the earher years, the latter have less effec t on the overall estimation. Nevertheless, the difficulty of predicting cash flows in later years and the inherent lack of confidence in these predictions are serious disadvantages of the (DCFRR) method. In this respec t (NPV)s are more usefm since they are calculated for each year of a project. Thus, a project with a favorable (NPV) in the early years is a promising one. 

In the later years, studies on flame quenching were inspired by different applications and were undertaken sporadically [22-24]. 

The first peptide syntheses were also initiated in Bonn. In the later years of his research activity, Helferich concentrated particularly on the chemistry of the sulfonamides. The chemistry of the sultams was of particular interest to him. As a spin-off from this work he developed a psychotropic drug, namely, Ospolot. 

Newton, Massachusetts, where they raised their four children Danielle, Sylvie, Raymond, and Claude. For many of the later years Roger and Dorothy enjoyed time in their delightful second home in Tourettes-sur-Loup in the south of France, where they were often generous hosts to friends and colleagues. 

Fluoride is rapidly distributed in plasma and deposited in bone and other calcified tissues that contain 99% of the body s fluoride the remainder is distributed between blood and soft tissues [52]. About 50% of daily fluoride intake is associated with the calcified tissues within 24 h and remaining 50% will be excreted in urine. This 50 50 distribution is strongly shifted to greater retention in the very young and probably towards greater excretion in the later years of life [8]. 

In Equation 8.3-1, D is depreciation, FCI is fixed-capital investment, t is the number of years over which the depreciation is accounted for, and S is the salvage value. Thus S is the value the plant could be sold for after the t years of operation. In this discussion we assume that the plant lasts for ten years, and that its salvage value is zero. With the straight-line method, annual depreciation costs are constant. Other methods, such as the sum-of-the-years-digits method, determine depreciation costs to be greater in the early years of the property than in the later years. Local regulatory laws generally define which method can be used to determine depreciation costs. 

During the later years of his life he worked as waterworks engineer and a science writer. In 1808 he compiled a Dictionary of Practical and Theoretical Chemistry [ii, iii]. 

Natural organic materials and various chemical byproducts represented a large proportion of the total world fertilizer supply until about the middle of the twentieth century in the later years of the century, however, the dependence shifted almost entirely to synthesized or chemically processed materials. Only by this means has it been possible to keep up with increasing populations,... 

Comparison of the various depreciation methods shows that the declining-balance and the sum-of-the-years-digits methods give similar results. In both cases, the depreciation costs are greater in the early-life years of the property than in the later years. Annual depreciation costs are constant when the straight-line, sinking-fund, or present-worth method is used. Because interest effects are included in the sinking-fund and present-worth methods, the annual decrease in asset value with these two methods is lower in the early-life years than in the... 

In summing up the later years of Smedley s life, Mary Philip (Mrs. Epps), a friend from KEVI and Newnham days, observed ... 

A central element in this process was the water controversy concerning whether Watt, Cavendish or Lavoisier should be recognized as the discoverer of the compound nature of water. I have examined this controversy, and the forces that drove it, in considerable detail elsewhere.1 In this chapter I focus on the way in which the controversy, together with Watt s self-fashioning in the later years of his life, radically transformed Watt s chemical reputation and in particular determined the extent to which he was recognized as a chemist at all. 

Between 1941 and 1949, Mills was Research Assistant, and then Research Fellow, Senior Research Fellow, and Tutor at the University. In the later years, he supervised the work of research students. In the system operated by Macbeth, the older research workers looked after the younger ones. Never, in his later life, did Mills have such an opportunity to control the work of others. Towards the end of this period in Adelaide, Mills was the senior author of a considerable number of publications.
