The bronze vase (Heraklion 2460) shown in Plate 2 and Fig. 1 was found in 1936 by workmen digging to lay pipes beside the main road between A. Ioannis and Teke (Knossos Survey no. 10). With it were the black-figure fragments shown in Plate 3 a. The find was briefly noticed in JHS lvi (1936) 150. The late T. J. Dunbabin had intended to publish the pieces but had written a detailed description of the bronze vase only, which I have drawn upon below.The bowl is 0·216 in diameter and 0·043 high, but the exact curve of the lower part is not certain. The bowl is made in one piece, with a slight inset at the edge. Over this fits the upper part. This is 0·218 in diameter (0·118 the inner diameter); its height from the inner edge is 0·04, from the outer edge 0·02. It carries two cast swing handles. The attachments for them are 0·046 long, smooth inside, and on the outside decorated with three heavy ribs of beading. The ‘scotiae’ between are marked by pairs of lines. The handles themselves are 0·086 wide, circular in section but flattened on the inside and outside, and with two beaded knobs. Between the handles are two gorgoneia: present widths 0·106 and 0·103. The faces are very broad. The eyelids are strongly marked and thicken at the edge, giving the impression that they are rolled back slightly from the staring eyeballs. There is an almost circular depression round the eyes which is only slightly shallower at the corners. The ridge of the eyebrows is very firm and a ridge runs vertically up the forehead like a tall bud. The nose is not, in its upper part, unduly broad; the fleshy part broadens very much at the base, leaving a considerable depression above it, slanting obliquely downwards. The cheek-bones are high, the angles of the jaw-bone very strongly marked and the chin consists of two bony prominences with a depression between.

A ridge of primeval mountains runs almost through Germany, in a direction nearly from west to east; the Hartz, the mountains of Thuringia, the Fichtelberg in Franconia, are different parts of it, which in their farther extent constitute the Riesenberg, and join the Carpathian mountains; the highest parts of this ridge are granite, and are flanked by alluvial and stratified mountains, consisting chiefly of limestone, marl, and sandstone; such at least is the tract of hills in which the caves to bé spoken of are situated, and over these hills the main road leads from Bayreuth to Erlang, or Nurenberg. Half way to this town lies Streitberg, where there is a post, and but three or four English miles distant from thence are the caves mentioned, near Gailenreuth and Klausstein, two small villages, insignificant in themselves, but become famous for the discoveries made in their neighbourhood. The tract of hills is there broken off by many small and narrow vallies, confined mostly by steep and high rocks, here and there overhanging, and threatening, as it were, to fall and crush all beneath; and every where thereabouts are to be met with objects, which suggest the idea of their being evident vestiges of some general and mighty catastrophe which happened in the primeval times of the globe.

It is near eleven years since that in travelling through Howison’s Poort,* one of the most picturesque of the many fine mountain passes through the quartzite ranges of the eastern province of the Cape Colony, my attention was drawn to a geological fact to which observation in other parts of the Colony has since led me to attach no little importance. In the construction of the main road from Port Elizabeth to Graham’s Town, many deep cuttings have been made in the solid quartzite rock. In many instances the rock seen in these works lost its crystalline character gradually, and assumed that of a hard blue sandstone, and at length nearly resembled the blue fossiliferous shales and sandstones of the Ecca.

The article presents the results of the analysis of the requirements of All Union State standard No18599-2001 to the thickness of the walls of pressure polyethylene pipes. An example of hydraulic calculation of a pipeline made of polyethylene PE 100 with a diameter d = 315 mm is considered. It is made in two versions - without taking into account and with allowance for dimensional tolerances stipulated by the requirements of the standard. The influence of the limitations on the thickness of the pipe walls on the values of their internal diameters and hydraulic characteristics is analyzed.

AbstractThe 1,2-diphenylethylenediamine-based neutral or cationic organogelator-templates, currently employed in the production of silica nanomaterials, were initially evaluated for their versatile gelation ability and found to be gelled in the majority of organic solvents tested. Scanning electron microscope and transmission electron microscope, images of neutral organogels made from different solvents revealed that they assembled into a plate-shaped, or rod-shaped morphology, respectively in ethanol or butan-1-ol and in acetonitrile or tetrahydrofurane. Similarly, a 1: 1 mixture (mass) of neutral and cationic gelators formed different morphologies in the solvents tested. Sol-gel polycondensation of tetraethoxy silane using either individual gels (neutral or cation) or a 1: 1 mixture of gels was explored. The experimental results and the scanning electron microscopy and transmission electron microscopy images revealed that silica nanotubes with an inner diameter of 82 nm and an outer diameter of 620 nm were obtained from the 1: 1 mixture of neutral and cationic gelator in ethanol, whereas silica nanoparticles were obtained using gels made in the other solvents tested.

Inspection railway are a re-design of railway that have been made in the Indonesian Railway Polytechnic. Inspection lorry repairs are carried out on the wheels, chassis, drive and body.The new lorry wheels are made of structural iron to reduce the total weight from 148 kg to 119 kg. The size of the wheel conus is the difference between the outer and inner diameter of 30 mm to minimize wheel friction with rails in the curved region. The chassis uses the ledder frame model with emphasis on the strength of 44.29 MPa and 0.095 MPa deflection to get optimal and reliable results on the 1067 track. The material uses galvanized hollow type iron weighing 125 kg. The environmentally friendly drive used in the railway inspection is an BLDC electric motor (brushless direct current) with a capacity of 2000 watts of power, a current of 35A and a rotational speed of 4250 Rpm. The railway inspection body is made of 3 layers fiber reinforced polymers of plastics (FRP) using a hand lay-up method that has a tensile stress value of 40.18 MPa and a strain value of 0.89%. The inspection body focuses on the aesthetics and ergonomics aspects in the form of a more attractive appearance, smoothness of design, passenger comfort and color harmony so that they have high selling.

Currently the noise factors influence on stationary workplaces is prevalent in the other harmful factors influence total share. The information proposed below reveal the gist of the technical solution related to devices for ensuring the workplace acoustic safety. Noise clipping is provided by digital technology. The technical result is expressed in increasing the noise cancellation efficiency in the device upper local zone, so at the user's head level. The device can be used on stationary workplaces, the technological process implementation on which does not require active physical movements. Product using reduces the load on the human auditory system and ensures its protection. Basic expressions are presented that allow noise control in a noisy space between loudspeakers. The noise protection device contains detecting microphones, a control unit for the active noise cancellation process, loudspeakers and a noise shield located on the frame. A specially designed shield is made in the spherical segment form, to the outer edge of which a rim on flexible brackets is attached with the possibility of detecting microphones free movement along it.The device bearing frame is made in a U-shaped form, in the upper part of which the loudspeakers are mounted with diaphragms facing each other.

The bronze piece here studied is in the possession of Sir John Beazley, and it is at his invitation that I publish it. I must thank him both for his invitation and for enabling me to study the object repeatedly and at leisure. It was acquired in Paris.The object is a thin, ovoid piece of bronze with a projection, representing the head of a snake, within the circle. The whole object is doubtless thought of as a coiled snake. The dimensions of the whole are: inner diameter from Α of ΝΑΙΩΙ to Ω of ΑΝΕΩΗΚΕΝ, 0·065 m.; distance from tip of snake's head to opposite inner edge, between Σ and Τ of ΕΣΤΡΑΤΟΥ, 0·050 m. The bronze is of a regular width, save that it widens slightly behind the projecting head; normal width, 0·008 m.; width behind head from outer edge to base of head, 0·010 m. Length of snake-head, 0·027 m. Average thickness, 0·003 m.; max. thickness of head, 0·005 m.The piece, which is covered with a green patina, is perfectly preserved save for a narrow strip where the surface has been removed, which appears as a black streak on the photograph. This may be original, and due to a flaw in casting, since the dots of the inscription, which are in its path, appear to be undamaged by it.

During the fourth season of excavation at Fishbourne work was spread over an area of about ten acres, most of it being concentrated on three main sites: the west wing of the main building, the eastern half of the north wing, and the southern half of the east wing. In addition, exploratory trenches were dug through the area to the north of the north wing and several trial excavations were made in gardens to the south of the modern main road. Previously, in December 1963 and January 1964, limited excavations had been undertaken in the garden of no. 65 Fishbourne Road, in the area of the greenhouses to the west of the main site, and in other gardens further west.

I should like to give you a very condensed progress report on some spectrophotometric measurements of objective-prism spectra made in collaboration with H. Leicher at Bonn. The procedure used is almost completely automatic. The measurements are made with the help of a semi-automatic fully digitized registering microphotometer constructed by Hög-Hamburg. The reductions are carried out with the aid of a number of interconnected programmes written for the computer IBM 7090, beginning with the output of the photometer in the form of punched cards and ending with the printing-out of the final two-dimensional classifications.

Three distinct kinds of rapid variations have been detected in the light curves of dwarf novae: rapid flickering, short period coherent oscillations, and quasi-periodic oscillations. The rapid flickering is seen in the light curves of most, if not all, dwarf novae, and is especially apparent during minimum light between eruptions. The flickering has a typical time scale of a few minutes or less and a typical amplitude of about .1 mag. The flickering is completely random and unpredictable; the power spectrum of flickering shows only a slow decrease from low to high frequencies. The observations of U Gem by Warner and Nather (1971) showed conclusively that most of the flickering is produced by variations in the luminosity of the bright spot near the outer edge of the accretion disk around the white dwarf in these close binary systems.
