At a recent meeting of the Institute, Mr. Sutton read an instructive paper on the method used by Milne in the construction of the Carlisle Table of Mortality, and the paper gave rise to an interesting discussion. I was surprised to find that it was the general opinion of members that Milne's description of his method is vague, and still more so to discover that more than one able investigator had expended much pains and ingenuity, unsuccessfully in my view, to unravel the mystery. Years ago I had studied Milne's explanations, and they seemed to me perfectly clear; and I had more or less tested his figures, and proved that they worked out correctly. So much was I satisfied, that it never occurred to me that the matter required further elucidation. But the remarks of Mr. Sutton in his paper, and of Mr. Manly in the-subsequent discussion, show that Milne has been very much misunderstood; or else that he has not only failed to explain his method, but that he has explained a method which he did not in the slightest degree adhere to, and that he thus has almost wilfully misled the student. Under these circumstances I may, perhaps, be pardoned if I give with some detail the results of my own researches,—which, since Mr. Sutton's paper was read, have been carried out to greater fulness—especially as I think that thereby may be vindicated the character of Milne for both lucidity and accuracy.

I was sorry to have missed the two papers by Captain K. D. Jones and Mr P. J. Houseley on the above subject, presented at a recent meeting of the Institute, and the subsequent discussion. Fortunately both Captain Jones and Mr. Houseley have been kind enough to let me see copies of their papers and I would like to add two pieces of information which may be of interest with reference to Captain Jones's paper.The first is in regard to the making of ‘the first decision’ in clear weather. Captain Jones says that most mariners on sighting a target decide on the risk, or the probable miss distance, by an accurate even if intuitive evaluation of aspect and range. (They must also take into account the relative bearing of the target and its speed relative to that of own ship.) For the purposes of his argument Captain Jones omits from the clear weather case the alternative method of using radar in assessing the risk or probable miss distance. Evidence on the comparative accuracies of these two methods may be of interest; a series of demonstration runs on the Predictor automatic plotting radar in Elettra lll in the English Channel provided an opportunity to obtain some such evidence.On one occasion which I have in mind, under conditions of clear visibility in daylight, a ship estimated at about 2000 tons was seen about 45° off the port bow at a (radar) range of 7 miles in a crossing situation.

An Introduction to Islam by David Waines consists of three parts:“Foundations,” “Islamic Teaching and Practice,” and “Islam in the ModernWorld.” The author begins by characteristically painting the picture of pre-Islamic pagan Arabia on the eve of Islam’s advent. He discusses the role andsignificance the pre-Islamic Arabs accorded their pantheon of deities, as wellas the (largely inherited) moral codes that governed their conduct in tribalsociety. Waines neatly ties this into what follows, where he discusses thebirth of Prophet Muhammad, the event of the Qur’an’s revelation, and theopposition he encountered from his fellow tribesmen in Makkah. This is followedby an analysis of the Qur’an’s significance, its conception of divinity,and the content and importance of the Hadith as a source of guidance forMuslims. The section is rounded off with examinations of such topics as the first period of civil strife (fitnah) after the Prophet’s death and the interestingbody of literature devoted to Muslim-Christian polemics in earlymedieval Islam.The transition from the first part of the book to the second part is ratherfluid, for the second part is essentially an elaboration of the themes discussedin the first. With remarkable ease and accuracy, the author elucidatesthe historical development and main features of Islamic law in both its theoryand practice. Returning to his earlier discussion on the Hadith, here hebriefly outlines how its corpus came to be collected. Readers unfamiliar withthe main theological controversies that confronted Islam in its formativeyears (e.g., the problem of free will and the status of the grave sinner) willfind the section devoted to Islamic theology fairly useful.Waines goes on to explain some of the principle Mu`tazilite andAsh`arite doctrines, and outlines some of the ideas of Neoplatonic Islamicphilosophy, albeit through the lenses of al-Ghazali’s famous refutation.Surprisingly, the author does not address any of the major developments inIslamic philosophy post-Ibn Rushd, such as the important work of theIshraqi (Illuminationist) school (incidentally, the founder of this school,Shihab al-Din Suhrawardi, was a contemporary of Ibn Rushd). The last twochapters are devoted to Sufism and Shi`ism, respectively. Although Wainesdoes misrepresent Ibn al-`Arabi’s metaphysics of Being by calling it a “system”(pp. 153 and 192), on the whole he presents the Islamic mystical traditionin a refreshing and informed manner. His section on Shi`ism is splendid.It is written with considerable care, and he effectively isolates the mainthemes characteristic of Twelver Shi`ite thought and practice.In the third and longest part of this work, Waines incorporates IbnBattutah’s travel accounts into the book’s narrative. This works very well, asit gives readers a sense of the diverse and rich cultural patterns that wereintricately woven into the fabric of fourteenth-century Islamic civilization.After reading through the section, this present reviewer could not help butmarvel at how the observations of a fourteenth-century traveler and legaljudge from Tangiers could so effectively contribute to a twenty-first centuryintroductory textbook on Islam. Additionally, Waines takes readers throughsome of the essential features of the three important “gunpowder” Muslimdynasties, devotes an interesting discussion to the role played by the mosquein a Muslim’s daily life, and outlines some of its different architectural andartistic expressions throughout Islamic history ...

This chapter overviews Chinese reception of Milton, with an emphasis on some of the most well-known Chinese translations of Paradise Lost. Close readings of these translations against Milton’s original demonstrate the difficulties of and resolutions for rendering Milton’s verse specific to Chinese. The subsequent discussion of the paratexts accompanying Chinese translations and of ‘introduction to world literature’ series gives a sense of the collaborative context that has shaped and continues to shape today’s general reception of Milton in China. That politically charged reception, eager to view Milton’s Satan as the embodiment of the poet’s revolutionary spirit, also dominates some recent works of Chinese literary criticism. The chapter ends by conceding that, while Milton scholarship in China has been relatively univocal and is still young, recent developments in world literature promise that innovative and intriguing work on Milton can be expected from China in the near future.

This chapter considers why contemporary analytic philosophers of religion have neglected liturgy and focused almost all of their attention on religious belief. Following Descartes, reflections on mental activity and the mind have been central in modern philosophy. But that has not prevented the emergence of philosophy of art, philosophy of language, and political philosophy, none of which deal with mental activity or the mind. So why not philosophy of liturgy? Several explanations are considered; but none is found to be fully satisfactory. The Introduction concludes with an explanation of how the subsequent discussion relates to liturgical theology and to anthropological ritual studies.

The Renewable Energy Directive and the Electricity Market Directive, both parts of the Clean Energy for all Europeans Package (issued in 2019), provide supranational rules for renewable energy communities and citizen energy communities. Since national transpositions need to be completed within two years, Austria has already drafted corresponding legislation. This article aims at providing a detailed comparison of the European guidelines and the transposition into Austrian law. The comparison not only shows how, and to what extent, the European guidelines are transposed into Austrian law, but also helps to identify loopholes and barriers. The subsequent discussion of these issues as well as positive aspects of the Austrian transposition may be advantageous for legislators and policy makers worldwide in their process of designing a coherent regulatory framework. It is concluded that experts from different areas (i.e., project developers, scientists concerned with energy communities, energy suppliers and grid operators) should be closely involved in the law-making process in order to introduce different perspectives so that a consistent and supportive regulatory framework for energy communities is created.

Natural flavor and fragrance market size is expected to grow steadily due to the rising consumer demand of natural ingredients. This market request is guided by the general opinion that the production of natural compounds leads to a reduction of pollution, with inherent advantages for the environment and people’s health. The biotransformation reactions have gained high relevance in the production of natural products. In this context, few pieces of research have described the role of microalgae in the oxidation of terpenoids. In this present study, we questioned the role of microalgal based oxidation in the synthesis of high-value flavors and fragrances. This study investigated the role of three different microalgae strains, Chlorella sp. (211.8b and 211.8p) and Chlorococcum sp. (JB3), in the oxidation of different terpenoid substrates: α-ionone, β-ionone, theaspirane and valencene. Unfortunately, the experimental data showed that the microalgal strains used are not responsible for the substrate oxidation. In fact, our experiments demonstrate that the transformation of the four starting compounds is a photochemical reaction that involves the oxygen as oxidant. Even though these findings cast a shadow on the use of these microorganisms for an industrial purpose, they open a new possible strategy to easily obtain nootkatone in a natural way by just using an aqueous medium, oxygen and light.

In two recent postmortem studies, Jeffrey Kordower and colleagues report new findings that open up for an interesting discussion on the status of GDNF/NRTN signaling in patients with Parkinson’s disease (PD), adding an interesting perspective on the, admittedly very limited, signs of restorative effects previously seen in GDNF/NRTN-treated patients. Their new findings show that the level of the GDNF signaling receptor Ret is overall reduced by about 65% relative to non-PD controls, and most severely, up to 80%, in nigral neurons containing α-synuclein inclusions, accompanied by impaired signaling downstream of the Ret receptor. Notably, however, the vast majority of the remaining nigral neurons retained a low level of Ret expression, and hence a threshold level of signaling. Further observations made in two patients who had received AAV-NRTN gene therapy 8–10 years earlier suggest the intriguing possibility that NRTN is able to restore Ret expression and upregulate its own signaling pathway. This “wind-up” mechanism, which is likely to depend on an interaction with dopaminergic transcription factor Nurr1, has therapeutic potential and should encourage renewed efforts to turn GDNF/NRTN therapy into success, once the recurring problem of under-dosing is resolved.
