scholarly journals Experiments and observations on electric conduction

According to the modern theory of electricity, metallic bodies, far from attracting the electric fluid, as is commonly believed, are of all bodies those which have the least attraction for that fluid, and being the best conductors for it, are entirely passive during its transit through them. In confirmation of these views, the author describes experiments in which the electric spark was found to have penetrated through the side of a glass globe blown to an extreme degree of thinness. An electric jar, from which the air had been partially exhausted, could not be made to receive as high a charge as when the contained air was of the usual density, and when entirely exhausted could not be charged in any sensible degree; when filled with condensed air on the other hand, it retained a higher charge than before. The heated and consequently rarefied air surrounding a red-hot iron rod is found to conduct electricity with great facility. The same property is observed in the flame from a blowpipe, which may be regarded as a hollow cone containing highly rarefied air; as also, in a larger scale, in that of a volcano. Sir H. Davy had concluded from his experiments on voltaic electricity, that the conducting powers of metals are diminished by heat; but Mr. Ritchie infers from several experiments which bear more directly upon the question, that the metals afford no exception to the general law, that in all bodies heat increases the conducting powers; and explains the apparent anomaly in Sir H. Davy’s experiments, by the dissipation of the electricity by the rarefied air surrounding the heated metals, which were used as conductors. He concludes his paper by describing an experiment which appears to establish, in respect to this law, a striking analogy between the electric and magnetic influences.

This paper analyzes the provisions of the Nigerian Companies and Allied Matters Act 2004 which, against the grain of general law rules on decrystallisation of floating charge, provides that a crystallised floating charge can decrystallise or refloat where the creditor withdraws from possession after the debtor has commenced payment or if the receiver, with consent of the creditor, is withdrawn. The analysis is relevant because the provision has dire implications for business sustainability since parties engage in debt transaction to sustain the going concern basis of their businesses. Bearing in mind that uncertainty pervades the boundaries between fixed and floating charge, the paper asks what is the priority status of a decrystallised floating charge as against a floating charge created prior to refloatation; and what is the relationship between the decrystallised floating charge and a fixed charge that predated the decrystallisation on the one hand and a fixed charge created post refloatation on the other hand. Using the case law and existing literature the paper showed that the statutory provision for decrystallisation of floating charge not only failed to clarify the general law rules on decrystallisation of floating charge, but it has cast a veil of uncertainty over the rights of parties to a debt transaction secured by floating charge. Since the provision can impact on the health of businesses, it behoves on the parties to be proactive in crafting debts contracts creating an interest secured by floating charge.

This paper confronts two conceptions of the past that one can find alternately in Ricœur’s thought. The first, encountered in Time and Narrative and elsewhere, apprehends the past as a soil of possibilities able to guide expectations directed towards the future; the second, taken back from Freud’s psychoanalysis, defines it as a charge that haunts the present as a compulsive repetition. There are two issues to this confrontation between a past that opens up a future and one that closes it. On the one hand, we want to show what effects Ricœur’s lectures of Freud have had on his own philosophy of time; on the other hand we want to reveal, in the light of the problem that rises from a haunting past, the practical scope of the idea of an indeterminate past

Gender issues become a very serious issue today. This is identified by a number of discourses on the women’s equal rights and men. Although the actual focus of gender studies is not limited to aspects of women, but also men. But in fact, the figure who is often marginalized is women. On the other hand, men often get more privileges in terms of rights and opportunities. Therefore, this discussion focuses on gender studies of women's aspects by comparing men's rights. Indonesian citizens have the particular rights to receive education, especially Islamic education. This paper designed to describe the problems of gender in education, the theoretical lens of Islamic education on gender equality, as well as the strategy towards gender equality in education.

People fear something, as the feeling is normal for a person. Fear reactions are essential for survival. Fear will triggered whenever an individual facing something scary or even confronted with something new that seems potentially dangerous. Phobia on the other hand is an intense feeling of fear towards objects, animals, activities, situations or persons. However, many people do not know they suffered from phobia. Any fear during childhood might develop into phobias. People with phobias are most likely to avoid any place or situation that might trigger their fear so that they feel relief. They also keep their phobia to themselves and not telling other people about it. Besides, they are most likely refuse to go to receive treatment from psychiatrist or therapist. This is due to the norm of the society that seeing psychiatrist or therapist means that person suffering from mental health, which is embarrassing. This paper identified the types of phobia among Malaysian for preliminary investigation for reducing phobia through gaming approach. The quantitative method based on questionnaires, which contains of 18 questions used in the random online survey. The set of questions are adapted from Fear of Spiders Questionnaire. The higher the marks are the higher the state of phobia of the individuals will be. It is hope that by identifying the types of phobia may use to suggest an alternative gaming tool in reducing phobia.

The author, after noticing the history of the subject, and the opposition which the assertion, “that the Zoë of naturalists is the larva of a common crab,” received, traces the progress of the development of the animal from the Zæa to the adult, and endeavours to demonstrate, that from the youngest to the most perfect form, the changes are the result of no sudden transformation, but produced by a gradual series of alterations contemporary with every succeeding moult; that the Zæa is connected with the Megalopa , and the latter with the adult by many intermediate gradations, each in itself scarcely appreciable, and progressively approximating nearer and nearer the more perfect stages. The author asserts that the development is earliest and most complete anteriorly; that when first born, the seventh or posterior segment of the head, one or more of the posterior segments of the pereion (thorax), and the penultimate of the pleon (abdomen) are wanting in the brachyurous Decapods; but that this general law loses somewhat of its force in the descending scale of development; and as it becomes less persistent, the animal approximates in the larval condition nearer to the form of the adult type; while on the other hand, the same appears to be a constant law of the depreciation in adult forms, as exhibited in the more or less aberrant Amphipoda, such as Cyrtophium, Dulichia , &c.

It is obviously impossible to draw definite conclusions as to the significance of the differences between our work and Gye's, and still less, of the differences between Gye's work and that of Murphy and of Flu. We can only say that in a fairly large series of experiments, extending over a period of 12 months, we have had absolutely no indication of the necessity of two factors in the production of the Rous sarcoma. In other words, we have been unable to duplicate either the results of Gye or the modified confirmations of his work by Murphy and Flu. We have shown that uncontrollable local and individual variations may produce results in occasional chicks which simulate satisfactory experiments, but when viewed as a whole, mean nothing. Because of the conflicting nature of results obtained by those who have undertaken to repeat the work, and on account of the difficulty of controlling all factors involved, we do not feel that it may be stated definitely that Gye's theory of the cause of cancer is wrong. On the other hand the theory apparently needs more evidence in its support if it is to receive further serious consideration. It is suggested, in order to untangle the subjéct as rapidly as possible, that future publications should include sufficient consecutive protocols to make the trend of the experiments obvious to the reader.

The purpose of this paper is to draw attention to a similarity between an ancient and a modern theory of living nature. There is no need to present the Aristotelian doctrine in full detail. I must rather apologize for repeating much that is well known. My endeavour is to offer it for comparison, and, incidentally, to clear it from misrepresentation. Uexküll's theory, on the other hand, is little known, and what is given here is an insufficient outline of it. I do not maintain that either doctrine is right. I am fully aware that the problem of the essence of living nature by no means admits of an éasy solution. In offering for consideration the comparison contained in this paper I would go no farther than owning my belief that the two authors here discussed, both thinkers who combine an intensely philosophical outlook with a wide biological experience, are worth the attention not only of the historian of science and philosophy, but also of the student of philosophical biology.

<p><em>This study is aimed to figure out  on how current legal device gives legal certainty over the excess of heritage partition (radd) in Algeria. The comparation between Islamic jurisprudence and the Algerian Family Law is used to analyse judicial consideration on which matters regarding the excess of heritage partition are based. The writer used normative law method which consists of statute approach and conceptual approach. The understanding of radd in Islamic scholars’ views differ from one another. Some scholars accept the concept and some do not. Those who disagree with radd consider that the excess of heritage should be given to bayt al mal as muslims representative. On the other hand, scholars who agree with the concept of radd ha</em><em>ve</em><em> also different opinions regarding who </em><em>are entitled</em><em> to receive the excess of heritage</em><em>. Some include spouse (husband or wife) but some exclude him/her. The Algerian Family Law gives provision in this case for a legal certanty, as it’s stated in </em><em>the article number 167 of the Algerian Family Code</em><em> that wife and husband are excluded to receive radd. They can only receive it in the absence of ashaba heirs/residuaries, other fixed share heirs, and  dzaw al arham (</em><em>uterine </em><em>relatives).</em></p><p><em>Penelitian ini bertujuan untuk mengetahui bagaimana perangkat hukum saat ini memberikan kepastian hukum atas kelebihan bagian warisan (<em>radd</em>) di Aljazair.

Abstract An electric charge located outside a closed metal box does not produce an electric field inside the box. On the other hand, an electric charge located inside the box can generate an electric field outside the box. A charge inside the box can therefore exert a force on a charge outside the box, but not vice-versa, in apparent contradiction of Newton’s third law.

Christianity boldly asserted that the eternal Logos had been manifested in the personal history of Jesus called Christ. Once this claim began to receive wide acceptance, the older ways of philosophizing characteristic of the classical ages were shaken. On the one hand, Christians affirmed positively that God had drawn nigh, disclosing himself in history to those who believed. On the other hand, they held that, apart from reliance upon this divine disclosure, the efforts of scientific reason to apprehend God were pitifully inadequate and perverse.
