AbstractAfter some introductory remarks on the German legal system and German legal politics, the main forms of datanet crime on the Internet are sketched. After that, one of the most important Internet-cases of the last decade, the CompuServe case, is discussed in some detail. One of the main problems of datanet crime is its global reach. The world-spanning nature of the cyberspace significantly enlarges the ability of offenders to commit crimes that will affect people in a variety of other countries. On the other hand, the jurisdiction of national criminal law cannot be expanded at will by any single nation. A transnational criminal law for the Internet is possible but should be restricted to the defence of universally (or nearly universally) accepted interests and values. In effect, it seems that the problems of computer-related crime on the Internet cannot be solved by criminal law alone.

Abstract The machine which is described in this communication was designed, after due consideration from both the theoretical and practical points of view, to flex rubber samples repeatedly without subjecting them to longitudinal traction, i.e., to flex them at constant length. The test-piece, cut in the form of strips from a sheet or from some particular part of an article, is fastened at each end; one end is held immovable, the other is fastened to a movable support which undergoes reciprocal motion. There seems to be no record of the existence of a machine of this type, in fact most specifications call for tests involving repeated traction. At a recent international rubber conference F. Jacobs described a machine with which test-specimens of special shape can be alternately flexed and subjected to impact, which has an influence on the results. Moreover this machine requires moulded test-specimens, so that it is impossible to test samples prepared from articles in the particular forms in which they are designed for service. At first thought it might be assumed that this machine operates in such a way that the samples are not subjected to longitudinal traction during flexing. In reality, since every deformation of a solid body involves a change in the arrangement of the elementary fibers, and since rubber is apparently no exception to this rule, a sequence of tensions and compressions occurs, the frequency of which is the same as that of the reciprocating motion; the amplitude can be changed at will, and the intensity of the stresses depends on the particular conditions, as the brief analysis which follows will attempt to show.

In the ‘English Historical Review’ for April (1893) Professor Ashley offers some criticisms upon the ‘Introduction to the Inquisition of 1517,’ contributed by me to the ‘Transactions of the Royal Historical Society’ for 1892. One object of that Introduction, it may be remembered, was to disprove the assertion of Professor Ashley that at the time when the evictions for inclosure began, and until ‘towards the end of the period,’ ‘the mass of copyholders’ had no legal security. In my view, the manorial records, the compilations of laws in the twelfth and thirteenth centuries, the practice of the courts, even the treatises of the jurists when critically scrutinised, led to the conclusion not merely that copyholders enjoyed protection in legal theory, but that their predecessors in title, the villeins, had done so before them. I drew no distinction in this matter between customary tenants and copyholders, as Professor Ashley appears to suppose, but showed that security extended even to villeins by blood, or ‘nativi,’ on custo-mary lands. Professor Ashley's proposition that ‘customary tenants’ and ‘copyholders’ were equivalent terms was never doubted by me, and is irrelevant to my argument. Indeed, it is assumed by me on the very pages to which he refers. ‘Mr. Leadam,’ he says, ‘draws a sharp distinction between “copyholders” on the one side and “tenants at will” on the other—a distinction which one may doubt whether the men of the sixteenth century would have felt so keenly.’ The distinction, as those who turn to the passage will see, is between ‘copyholders,’ used in Fitzherbert's sense as equivalent to customary tenants, who were ‘tenants at will according to the custom of the manor,’ and ‘tenants at will at Common Law.’

387. Although the general character of the reactions which cause repulsion under the influence of radiation is now understood, much light may he thrown on the subject by an experimental examination of the direction and strength of the lines of pressure inside the case of a radiometer on which light is allowed to fall. Radiation will pass almost unimpeded through a very thin, colourless and transparent substance such as mica, but molecular pressure or stress is arrested by such a body (232). By introducing fixed or movable screens in various parts of the case of a radiometer, the direction of pressure can be determined at will, and its force can be modified in many ways, whilst all the other conditions of the experiment remain unchanged. In the present Part I propose to give the results of a long series of experiments on the action of thin mica screens in modifying the movements of the fly of a radiometer; I shall examine the action of the residual gas, the action of the sides of the glass case, and the applicability of the information so afforded to the construction of instruments of greatly increased sensitiveness for the purposes of research and illustration; and I shall also describe other experiments which have been tried from time to time during the last few years—experiments which at the time were isolated in their bearings, but which now fit into their places.

After premising that, at the present time, it is the generally received opinion that water is a compound of oxygen and hydrogen, the author states that he now brings forward an experiment which proves, not that water is a compound, but really a simple element, the generator of oxygen and hydrogen, since, without being decomposed, a volume of water being given, it may be entirely transformed at will, either into oxygen or into hydrogen. Thus, he considers, it is no longer a decomposition of pre-existing elements which is effected, but really a gaseous transformation into two “sub-elements” which are formed at the expense of the water, by the transposition of its combined or coercitive electricity which places itself in excess in the water which becomes oxygen, at the expense of another volume which becomes hydrogen. He considers that this will, no doubt, appear very extraordinary, but that nevertheless it is now “un fait accompli et acquis a la science.” After describing the experiments which he considers support his doctrine, the author concludes by observing that these experiments prove,— 1st, that contrary to the indefensible theory, a compound electric fluid which is decomposed and recomposed, there is a true transfer of fluid in the current, which besides would be sufficiently evident by its motive power. 2nd. That the electric fluid is really the coercitive agent of cohesion. 3rd. That water is not a compound, is not an oxide, but truly a first element, the generator of oxygen and of hydrogen. 4th. In fine, it reveals a power unknown until now, and that very likely many other bodies are in the same case as water.

Computer software media has long had intrinsic similarities to books...so why may one be borrowed in a library and not the other? The answer lies in the context and history of how computer media came to be. In this essay I explore the early history of software distribution, where many different proposals fought to succeed. I provide an overview of the software industry’s early embrace of copy-protected floppy disks as a distribution medium, and how they harmed the notion of software as a borrowable medium. Lastly, I cover how CD-ROM materials were treated as books by publishers and libraries, yet failed to realize this premise with long-term success. I argue that a combination of industry actions and technological constraints over four decades caused computer software to fail to succeed as a tangible medium that can be borrowed like a book, lent, or resold at will.

In this study, the effects of various agricultural LED lights (LED NN), including single red LED (R), single blue LED (B), and four combinations of blue, red, and warm white (W) LED (BR, BRW1, BRW2, BRW3) on the growth and development of C. militaris (Link.) Fries were evaluated in vitro. After 7 days, samples subjected to LED NN showed shorter sporocarp sprouting time and higher sprouting ratio than the control, which was subjected to T5 fluorescent light. After 2 months, LED lights with high red ratio, such as single red LED and LED BR, had suppressing effect on the growth and development of C. militaris (Link.) Fries. On the other hand, combinations of red, blue, and warm white such as LED BRW1, LED BRW2, and LED BRW3 had the positive impact on the growth and development of this fungus. Notably, samples subjected to LED BRW2 reached 5.79 cm in height, fresh biomass of 3.67 g/20 samples. Cordycepin and Adenosine levels were 64.2 and 6.37 mg/100 g fresh mass, respectively. All of studied  indicators were the higher compared to those of the control and other LED lighting schemes. Therefore, it can be conlcuded that LED lighting combination with BRW2 ratio of 1:5:1 and luminous intensity of 45±2 µmol.m-2.s-1 (511,59 Lux) was suitable for the growth and development of C. militaris (Link.) Friesand a potential replacement of fluorescent light for C. militaris (Link.) Friesin vitro propagation.

Abstract The use of light-emitting diodes (LEDs) is a recent concerned application in the indoor crop system of the modern plant production. In our research, we evaluated the influence of four monochromic LED lights including 100% White (W), Yellow (Y), Red (R) and Blue (B) in comparison to solar lightening condition (GR) as a control. In this regard, some morphological characteristics and biochemical content of the common outdoor ‘Iceberg’ lettuce (Lactuca sativa L.) was measured. The results show that leaf length, leaf area and total head weight were significantly greater in the plants grown under B LED, while all the other physical parameters were significantly higher in the plants grown under GR environmental conditions. On the other hand, chlorophyll (Chl), carotenoids (Car), and nitrate content were also influenced by different light treatments. Plants grown under LED light treatment resulted in significantly higher chlorophyll content compared to the control. However, significantly greater carotenoid content was in the plants grown under GR condition. The highest total chlorophyll content was recorded under B and R LED, whereas the lowest was in the GR condition. The lowest nitrate content in the blade and petiole was recorded in the plants grown under Y LED, while the highest nitrate content was recorded in the GR. Based on our result, it is possible to grow and improve some quality parameters of common outdoor ‘iceberg’ lettuce under LED where the solar light is limited or unavailable. Thus, plants performed better under GR light conditions than monochromic LEDs; however, some LED lights could improve some quality parameters and biochemical contents in the ‘iceberg’ lettuce variety.

1959 was a watershed for the Dave Brubeck Quartet. Not only was it the year of Brubeck’s most famous creative project, Time Out, but it also marked the midpoint of the “classic” Quartet with Paul Desmond, which was formed in 1951 and disbanded in 1967. This chapter discloses the specific factors involved in the production of Time Out. These include early concert performances of the repertoire, the recording sessions, and decisions concerning the album’s title, cover art, and liner notes. The other trajectory followed here concerns several important matters that were uppermost in Brubeck’s life and career at that time. Chief among them were an enormous amount of domestic and international travel, a high-profile stand against racism and segregation in the South, an all-out effort to finish his musical and see it produced on Broadway, and a series of performances with the New York Philharmonic in Carnegie Hall.
