Detailed gravity surveys were made in Camaguey Province, Cuba, as part of a systematic exploration program conducted by the U. S. Geological Survey on behalf of the General Services Administration to locate deposits of refractory‐grade chromite. During the period August 4, 1954, to April 5, 1956, a total of 41,921 gravity stations were established in nine areas embracing about 11.8 square miles in the Camaguey chromite district. The results of the surveys were used in connection with information obtained in geologic investigations to guide exploratory drilling. Gravimeters with low scale constants were used in making measurements sufficiently accurate to delimit anomalies as small as 0.5 gravity unit. The measurements were made over 20×40 and 30×60 meter grids and at stations 20 and 30 meters apart, respectively, along intermediate traverses in anomalous areas. Gravity differences were determined by single observations at individual stations, observing base stations hourly, and re‐observing a few stations to check drift and accuracy of measurement. About 11 percent of the stations established had to be re‐run because of errors in closure, microseisms, and instrument trouble. A large number of anomalies were found and evaluated according to geology, areal extent, and gravity relief. Depths to disturbing hypothetical bodies were computed to guide drilling. Test drilling of 106 positive anomalies revealed that ten features overlie deposits of chromite and 89 occur over bodies of other dense materials. The other seven anomalies were not explained by materials found in drilling. Core drilling on five of the chromite deposits revealed about 236,000 tons of chromite. An additional estimated 12,000 tons are contained in three deposits which were not blocked out. No estimate was made of the tonnage in two small deposits.

The Lower Silurian rocks of Scotland, largely developed as they are in the south, and in spite of the great labour that has been bestowed upon them, are by far the least known of all the fossiliferous formations of that country. While the maps of the Government Geological Survey are coloured in all the subdivisions of the strata of the other formations included in their area, the Lower Silurians are merely indicated by a common purple tint, and not the slightest attempt at a subdivision is made. Even the single bed of Limestone they contain, below the horizon of that of the W. coast, is doubtfully referred to the Llandeilo, and the sign of interrogation is carefully placed before its title. Nicol, Harkness, J. C. Moore, and many other eminent geologists, have worked different portions of these ancient deposits since the publication of “The Silurian System,” but as yet very little progress has really been made in correlating its different parts with those of the type formation of the sister country.

The order and modalities of cross-member state redistribution as well as the net financial position of the member states are one of the most widely discussed aspects of European integration. The paper addresses selected issues in the current debate on the EU budget for the period 2007 to 2013 and introduces four scenarios. The first is identical to the European Commission's proposal; the second is based on reducing the budget to 1% of the EU's GNI, as proposed by the six net-payer countries, while maintaining the expenditure structure of the Commission's proposal. The next two scenarios represent radical reforms: one of them also features a '1% EU GNI'; however, the expenditures for providing 'EU-wide value-added' are left unchanged and it is envisaged that the requisite cuts will be made in the expenditures earmarked for cohesion. The other reform scenario is different from the former one in that the cohesion-related expenditures are left unchanged and the expenditures for providing 'EU-wide value-added' are reduced. After the comparison of the various scenarios, the allocation of transfers to the new member states in terms of the conditions prevailing in the different scenarios is analysed.

An investigation on the properties of Tenun Pahang fabric performances using alternative yarns was conducted. The studies were made in order to evaluate whether the Tenun Pahang fabric could be produced economically and at the same time maintain the fabric quality. Traditional Tenun Pahang fabric uses silk for both warp and weft. For this project, two alternative yarns were used which were bamboo and modal, which were a little lower in cost compared to silk. These yarns were woven with two variations, one with the yarns as weft only while maintaining the silk warp and the other with both warp and weft using the alternative yarns. Four (4) physical testings and three (3) mechanical testings conducted on the fabric samples. The fabric samples were evaluated including weight, thickness, thread density, crease recovery angle, stiffness and drapability. The results show that modal/silk and bamboo silk fabrics are comparable in terms of stiffness and drapability, hence they have the potential to replace 100% silk Tenun Pahang.

Intermedialität wird hier systematisch an Musik, Literatur, visuelle Kunst und Film dargestellt. Den Anfang machen allgemeine Überlegungen zu Materialität und Medium in diesen verschiedenen Künsten. Im Weiteren werden unter dem Aspekt ›Bimedialität‹ verschiedene Beispiele vorgestellt, die jeweils aus zwei Medien bestehen (z.B. Musikfilm, das Lied oder Schriftbilder). Dabei folgen wir der Frage, ob und wie jeweils eines der beiden Medien eine Vorrangstellung bekommt. Der abschließende Teil behandelt „intermediale Bezüge in Monomedialität“. Hier geht es um monomediale Darstellungen, denen aber eine Beschäftigung mit einem anderen Medium vorangegangen ist. Das ist etwa dann der Fall, wenn ein Schriftsteller über ein Bild schreibt, ohne daß dieses (im Text) zu sehen ist. In this article, we offer a systematic description of intermedia relations across music, literature, the visual arts, and film. Beginning with some general reflections on materiality and medium in these diverse fields of art, we then offer various examples consisting of two media (e.g. music film, song, images in writing). We pursue the question if, and how, one of the two media may take priority over the other. In our conclusion, we deal with „intermedia relations in monomediality“. This section focuses on artistic representations made in one medium, but based on reflections on another medium. For instance, this is the case when a novelist writes about a picture without having this picture reprinted in the text.

Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.

The proposed new geological era, The Anthropocene (a.k.a. Age of Humans, Age of Man), marking human domination of the planet long called Mother Earth, is truly The Age of the Motherfucker. The ecocide of the Anthropocene is the responsibility of Man, the Western- and masculine-identified corporate, military, intellectual, and political class that masks itself as the exemplar of the civilized and the human. The word motherfucker was invented by the enslaved children of White slave masters to name their mothers’ rapist/owners. Man’s strategic motherfucking, from the personal to the planetary, is invasion, exploitation, spirit-breaking, extraction and toxic wasting of individuals, communities, and lands, for reasons of pleasure, plunder, and profit. Ecocide is attempted deicide of Mother Nature-Earth, reflecting Man’s goal to become the god he first made in his own image. The motivational word Motherfucker has a flip side, further revealing the Anthropocene as it signifies an outstanding, formidable, and inexorable force. Mother Nature-Earth is that “Mutha’ ”—one defying translation into heteropatriarchal classifications of gender, one capable of overwhelming Man, and not the other way around. Drawing upon Indigenous and African American scholarship; ecofeminism; ecowomanism; green activism; femme, queer, and gender non-binary philosophies; literature and arts; Afrofuturism; and popular culture, Call Your “Mutha’ ” contends that the Anthropocene is not evidence of Man’s supremacy over nature, but that Mother Nature-Earth, faced with disrespect, is going away. It is imperative now to call the “Mutha’ ” by decolonizing land, bodies, and minds, ending rapism, feeding the green, renewing sustaining patterns, and affirming devotion to Mother Nature-Earth.

Introduction.—The systematic exploration of Ptolemais (modern Tolmeita), in Cyrenaica, began in 1935 under the auspices of the Italian Government, and under the direction of the first-named writer. The general programme of excavation took into consideration not only the important Hellenistic period, which gave the city its name and saw its first development as an autonomous trading-centre, but also the late-Roman age when, upon Diocletian's reforms, Ptolemais became capital of the new province of Libya Pentapolis and a Metropolitan See, later occupied by Bishop Synesius.As one of several starting-points for the study of this later period, there was selected the area first noted by the Beecheys as containing ‘heaps of columns’, which later yielded the monumental inscriptions of Valentinian, Arcadius, and Honorius, published by Oliverio. Here excavation soon brought to light a decumanus, running from the major cardo on the west towards the great Byzantine fortress on the east. Architectural and other discoveries made in 1935–36 justified the provisional title ‘Monumental Street’ assigned to this ancient thoroughfare. In terms of the general town-plan, which is extremely regular, this street may be called ‘Decumanus II North’, since two rows of long rectangular insulae separate it from the Decumanus Maximus leading to the West Gate, still erect. The clearing of the Monumental Street and its frontages revealed the well-known Maenad reliefs, attributed to the sculptor Callimachus, a late-Roman triple Triumphal Arch, and fragments of monumental inscriptions similar in character to those previously published from the same area.

Studies were made in 5 monkeys, 7 rabbits, and 33 cats of the effect of gram-negative endotoxin on aortic, pulmonary artery (PAP), and portal venous (PVP) pressures; and on changes in weight of a short segment of intestine. Studies of blood pooling were also made in 12 cats. The responses in these species were compared with those previously observed in the dog. Although variable degrees of hypotension developed at one time or another in all animals following injection of endotoxin, the early precipitous hypotension that characteristically occurs in the dog was observed only in the cat. However, in this species the dramatic fall in pressure could be ascribed to pulmonary vascular constriction and acute right ventricular hypertension and failure, and not to splanchnic pooling. PAP also became elevated in the monkey and the rabbit, but usually was of lesser magnitude and did not appear to explain the development of the relatively late hypotension that occurred in these species. The absence of significant increases in gut weight and the minor increments in PVP in all animals indicate that in none of these species is hepatic vein constriction and splanchnic pooling a significant mechanism in producing early shock as it is in the dog. Pathologic gross and microscopic studies in the monkey and gross examinations in the other species supported this conclusion.

In February 1704, a Boston laborer named Thomas Lea found himself surrounded by townspeople as he lay on his deathbed. These spectators had gathered hoping to hear a much anticipated confession of the crimes they believed Lea had committed fifteen years earlier during the Dominion of New England. In Suffolk County, many townspeople had long maintained that Lea and others had used the confusion and chaos generated by the unsettling political and legal transformations introduced to New England during the 1680s to surreptitiously gain legal title to the estate of a prosperous Braintree, Massachusetts, landowner named William Penn. Standing by Lea's bedside, one witness, who believed Lea had perjured himself at the 1689 probate administration of Penn's estate, demanded: “Thomas can you as you are going out of the World answer at the Tribunal of God to the Will of Mr Penns, which you have sworn to[?]” “Was Mr Penn living or Dead when this Will was Made?” In the presence of assembled witnesses, Lea acknowledged, “he was dead.” Other townspeople pressed Lea to reveal the role he played in what many believed had been a murder for inheritance scheme. They reminded Lea that Penn's corpse had been found covered “in blood, in his own dung” with “a hole in his back, that you might turn your two fingers into it” and, even more disturbing, “one of his [Penn's] stones in his codd [scrotum] was broken all to pieces.” Averting the onlookers' gaze, Lea “turned his head aside the other way, saying what I did I was hired to do.” For these witnesses, the death-bed confession confirmed the rumors of Lea's crimes and strengthened their belief that a wave of corruption introduced in the 1680s had sabotaged New England's distinctive Puritan jurisprudence. Indeed, townspeople had labored for years to overturn the 1689 probate of Penn's estate in an effort forestall the crown's efforts to bring New England into political and legal conformity with the dictates of the growing English empire.
