This work investigates a previously unknown phenomenon taking place when a large carrier ship moves in a channel made by an icebreaker narrower than the carrier ship. Usually, the studies of these movement conditions assumed the center line of the ship to coincide with the channel axis and the interaction of ship sides with channel edges to be symmetric. However, the observations made in Ice Basin and in real conditions have shown that in most of cases interaction of ship sides with channel edges is not symmetric. The ship moving in the channel breaks ice only with one of her sides, the other side only rubbing against the edge. The numerical assessments of ship position stability in the channel given in this paper made it possible to understand how this interaction becomes asymmetric. The study also yielded ice resistance assessments for a large carrier ship moving along the channel in these asymmetric conditions.

Sprang is an ancient textile method without knots, worked on a set of threads that have been arranged on a frame. This technique used by people for thousands of years was almost forgotten since the beginning of the industrial revolution. The peculiarity of this type of braiding is that you have a mirror image and for every row of work, you can have two rows of fabric. It is possible to create a variety of interesting patterns and the pieces that are created have sideways that can stretch. Some methods were used and then abandoned, but this one keeps coming back. Sprang is an ideal technique for making human clothing. We tried to create a replica sash that was made in Ţinutul Pădurenilor (Pădureni Land) using a circular warp sprang. There is a center line of symmetry around which on one side we have threads in Z twist and on the other side in S twist. The sash grew out from that middle line. It was done in interlinking technique that gives it a great elasticity.

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.

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.

Descriptions of larvae of Procladius denticulatus, Procladius culiciformis, Procladius freemani, and Procladius bellus collected from Yellowknife Bay (lat., 62°25′; long., 114°20′) are given. Procladius denticulatus was separated from the other species by its large size, a character which always proved distinctive. Procladius culiciformis and P. freemani were separated from one another through several measurements including those of the basal antennal segment and the basal palpal segment. Almost all characters of the head were useful in distinguishing the much smaller P. bellus from the other species.

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.

In the present state of our knowledge of the Neolithic period in England, and especially as regards its pottery, any light that can be thrown upon it is welcome, and it is on that account that I have brought before the Society a report on two discoveries of Neolithic remains: at Pangbourne, Berks., and Caversham, Oxon.It is greatly to be regretted that owing to the circumstances of the discovery accurate observations could not be made. In May, 1928, workmen were engaged in levelling ground to make a tennis court, at “Farmhili,” Courtlands Hill, Pangbourne, and in doing so came upon, and, as is unhappily so often the case, disturbed and partly smashed a human skeleton, other animal bones, of which a few only survive, and a large bowl of coarse pottery, definitely of Neolithic type. It would seem that when found the bowl was imore or less complete, but Mr. G. W. Smith, of Reading, who visited the spot the day after the discovery, was only able to find about two-thirds of the vessel, in fragments, on the rubbish heaps of excavated material. These fragments, together with the other remains, were presented by the owner of the land, Lt.-Com. W. S. Macilwaine, R.N., to the Reading Museum, where the writer had the opportunity of examining them.
