ABSTRACT Two construction aggregate companies, Cemex and Hanson Aggregates, operate respective crushed stone quarries on the east and west slopes of Mount Zion in Clayton, California. These sidehill quarries utilize a single highwall and mine Jurassic diabase of the Coast Range ophiolite that formed as a sheeted dike complex. Hydrothermal veins, some containing 20%–30% disseminated pyrite and chalcopyrite, cut the diabase. The east quarry, operated by Cemex, was started by the Harrison-Birdwell Company in 1947. The west quarry, operated by Hanson, was started by the Henry J. Kaiser Sand and Gravel Company in 1954. The Cemex quarry highwall is visible as you come into the city of Clayton on Marsh Creek Road, with a height of ~280 m (920 ft). The height of the highwall at the Hanson quarry is ~215 m (700 ft). Both operations remove weathered diabase overburden to expose fresh diabase, which is drilled, blasted, and hauled to the plant for processing. To ensure aggregate is suitable for construction, quality assurance testing is conducted in accordance with the specifications of various agencies. These quarries supply the surrounding area with aggregate for hospitals, schools, highways, dams, and other buildings. Noteworthy projects supplied by the Clayton quarries include the Concord BART Station, Interstate-680, Interstate-580, Calaveras Dam, Sherman Island Levee, Highway 4, Highway 24, and Bay Bridge epoxy asphalt. Before aggregate was mined, Mount Zion was the site of a copper rush from 1862 to 1864. Gold and silver were also reported in various assays from the Clayton district. Although prospecting created excitement around Clayton, no productive orebodies were ever discovered.

Gunung Anyar Tambak is one of the villages that is located adjacent to the UPN "Veteran" campus in East Java. Most (2/3) of the Gunung Anyar Tambak area is the pond area, which has the main yield is milkfish. Besides being sold in fresh form, milkfish from ponds from Gunung Anyar Tambak are also processed into a variety of processed products including shredded, crackers, soft thorns and milkfish “sapit”. Milkfish “Sapit” is a processed milkfish which is unique in its serving. The milkfish are clamped using bamboo stems and then processed using a choice of spices that make a distinctive taste in this dish. Processing by burning, causing a distinctive aroma that is not forgotten. Barokah is one of the community groups of “sapit” milkfish processing in RW I of Gunung Anyar Tambak Village which consists of 6 people. Chairman of UD. Barokan is Hj's. Khasibah, explained that most of the milkfish produced are only fulfilling orders from the surrounding area and orders from outside the city to be used as souvenirs typical of Surabaya. From observations and interviews it is known that the problem in processing milkfish is a very simple packaging that is a very thin plastic bag that is not closed. The second problem is that the packaging has no labeling at all, even though the label can identify the identity of the product in the package. The importance of labels on food products in addition to being the identity of the packaged product is also a communication between producers and consumers. Therefore a very absolute label must be given to the marketed food products. Training has been conducted on packaging and labeling milkfish “sapit” in UD. BAROKAH, Gunung Anyar Tambak, Surabaya. Before being packed with a vacuum packer, milkfish saplings are first dried in a cabinet dryer for 3 hours at 60°C. Labeling on milkfish packaging is in accordance with the law on food labeling on primary (plastic) and secondary (carton) packaging. In addition to providing training, our team also donates dryers and Vacuum Sealers.

Foundation myths are a crucial component of many Greek cities’ identities. But the mythic tradition also represents many cities and their spaces before they were cities at all. This study examines three of these ‘prefoundational’ narratives: stories of cities-before-cities that prepare, configure, or reconfigure, in a conceptual sense, the mythic ground for foundation. ‘Prefoundational’ myths vary in both form and function. Thebes, before it was Thebes, is represented as a trackless and unfortified backwater. Croton, like many Greek cities in south Italy, credited Heracles with a kind of ‘prefounding’, accomplished on his journey from the West back to central Greece. And the Athenian acropolis was the object of a quarrel between Athena and Poseidon, the results of which gave the city its name and permanently marked its topography. In each case, ‘prefoundational’ myth plays a crucial role in representing ideology, identity, and civic topography.

On a warm summer afternoon in 1561, Calvin’s chief editor donned a heavy stole, thick robes, and a gleaming tiara and proceeded to strut and fret his hour upon the stage in a comedy of his own devising. For little more than a century, Christians in the West had celebrated on August 6th Christ’s Transfiguration as the son of God in shining robes. But on this Sunday in Geneva, the city council, consistory, and an audience fresh from having attended edifying sermons at morning service gathered to applaud the transfiguration of the learned Conrad Badius into the title role of ...

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.

Sedimentary Unit

The highly deformed section at Open Bay is one of the few good exposures of a thick sedimentary unit within the prebatholithic rocks along coastal British Columbia. It provides new structural information relating to emplacement of a part of the Coast Range batholith and it contains an important Upper Triassic fauna unusually well represented. Structural and paleontological analyses are mutually supporting and are purposely combined in one paper.Thirteen ammonite genera from 14 localities clearly substantiate McLearn's tentative assignment to the Tropites subbullatus zone (Upper Karnian) and suggest a restriction to the T. dilleri subzone as defined in northern California.Contrary to an earlier view, the beds are lithologically similar across the whole bay except for variations in the intensity of deformation and thermal alteration. Their contact with slightly older relatively undeformed flows is apparently a zone of dislocation. Stratigraphic thicknesses cannot be measured with confidence, and subdivision into "Marble Bay Formation" and "Open Bay Group" cannot be accepted. Open Bay Formation is redefined to include all the folded marble and interbedded pillow lava at Open Bay. Lithologic and biostratigraphic correlation is suggested with the lower middle part of the Quatsino Formation on Iron River, 24 miles to the southwest. Basalt flows and pillowed volcanics west of Open Bay are correlated with the Texada Formation within the Karmutsen Group.The predominant folding is shown to precede, accompany, and follow intrusion of numerous andesitic pods and to precede emplacement of quartz diorite of the batholith. Structural asymmetry is shown to have originated through gentle cross-folding and emplacement of minor intrusives during deformation.

Northern Wall

On 4 March 1554 some hundreds of London schoolboys fought a mock battle on Finsbury Field outside the northern wall of the city. Boys have always gratified their innate romanticism by playing at war, yet this incident, organized between several schools, was overtly political and implicitly religious in character. It almost resulted in tragedy, and, though scarcely noticed by historians, it does not fail to throw Ught upon London society and opinion during a major crisis of Tudor history. The present essay aims to discuss the factual evidence and its sources; thereafter to clarify the broader context and significance of the affair by briefer reference to a few comparable events which marked the Reformation struggle elsewhere. The London battle relates closely to two events in the reign of Mary Tudor: her marriage with Philip of Spain and the dangerous Kentish rebellion led by the younger Sir Thomas Wyatt. The latter’s objectives were to seize the government, prevent the marriage, and, in all probability, to place the Princess Elizabeth on the throne as the figurehead of a Protestant regime in Church and State. While Wyatt himself showed few signs of evangelical piety, the notion of a merely political revolt can no longer be maintained. Professor Malcolm R. Thorp has recendy examined in detail the lives of all the numerous known leaders, and has proved that in almost every case they display clear records of Protestant conviction. It is, moreover, common knowledge that Kent, with its exceptionally large Protestant population, provided at this moment the best possible recruiting-area in England for an attack upon the Catholic government. Though the London militia treasonably went over to Wyatt, the magnates with their retinues and associates rallied around the legal sovereign. Denied boats and bridges near the capital, Wyatt finally crossed the Thames at Kingston, but then failed to enter London from the west. By 8 February 1554 his movement had collapsed, though his execution did not occur until 11 April.

The Lower Greensand (LGS) forms the second most important aquifer in the London Basin but, being largely absent beneath the city itself, has received much less attention than the ubiquitous overlying Chalk aquifer. While the general directions of groundwater flow in the Chalk are well established, there has been much less certainty about flow in the LGS owing to regionally sparse borehole information. This study focuses on two hitherto uncertain aspects of the confined aquifer: the sources of recharge to the west-central London Basin around Slough, and the fate of LGS water where the aquifer thins out on the flank of the London Platform in the Gravesend–Medway–Sheppey area on the southern side of the basin. The application of hydrogeochemical techniques including environmental isotopes indicates that recharge to the Slough area is derived from the northern LGS outcrop, probably supplemented by downward leakage from the Chalk, while upward leakage from the LGS in North Kent is mixing with Chalk water to the extent that some Chalk boreholes on the Isle of Sheppey are abstracting high proportions of water with an LGS fingerprint. In doing so, this study demonstrates the value of re-examining previously published data from a fresh perspective.Thematic collection: This article is part of the Hydrogeology of Sandstone collection available at: https://www.lyellcollection.org/cc/hydrogeology-of-sandstone

Ballistic Trauma

There is currently a lack of information regarding the prevalence of and characteristics associated with blunt force trauma related homicides in South Africa. Information relating to the patterns of blunt force trauma could assist in the development and implementation of interventions targeted at specific areas or individuals as well as direct future research towards areas in need of investigation. This study is a 5-year retrospective review of autopsy reports obtained from Salt River Mortuary (Cape Town, South Africa). The prevalence of blunt force trauma was considered for unnatural deaths with a focus on homicide. The patterns of homicidal blunt force trauma are also presented. A total of 15 519 autopsy cases was analysed. In 1198 (7.72%) of these cases, the cause of death was found to be blunt force trauma and 828 (5.32%) of these cases were classified as homicides. Approximately 11% of blunt force homicide cases occurred in combination with sharp and/or ballistic trauma. Men from poor socio-economic areas were shown to be most at risk of blunt force homicide in the City of Cape Town.

AbstractThe word of the Lord of Hosts came to me: These are the words of the Lord of Hosts: I have been jealous for Zion, fiercely jelous for her. Now, says the Lord, I have come back to Zion and I will dwell in Jerusalem. Jerusalem shall be called the City of Truth, and the mountain of the Lord of Hosts shall be called the Holy Montain. These are the words of the Lord of Hosts: Once again shall old men and old women sit in the streets of Jerusalem, each leaning on a stick because of their great age; and the streets of the city shall be full of boys and girls, playing in the streets. These are the words of the Lord of Hosts: Even if it may seem impossible to the survivors of this nation on that day, will it also seem impossible to me? This is the very words of the Lord of Hosts. These are the words of the Lord of Hosts: See I will rescue my people from the countries of the east and the west, and bring them back to live in Jerusalem. They shall be my people, and I will be their God, in truth and justice. Zechariah 8,1-8 (NEB)

AbstractThe fortifications of the Hellenistic and Roman city of Tocra are over 2 km long (including the sea-wall) and comprise a curtain wall up to 2 m wide flanked by 31 rectangular towers. Three main structural phases were noted in the survey carried out in 1966 by David Smith: (1) Hellenistic walls of isodomic ashlar, (2) later Hellenistic work of isodomic ashlar with bevelled edges, associated with the indented trace along the south rampart, and (3) an extensive rebuild of plain ashlar blocks including the towers and reconstruction to the East and West Gates, dateable, on the basis of Procopius, to the reign of Justinian. The general significance of the fortifications at Tocra is considered in the second part: these include the Hellenistic indented trace along the south side, later reinforced by towers in the sixth century AD. Also of wider importance was the use of an outer wall or proteichisma, and the pentagonal, pointed towers at the two main gates. Both these elements were unusual in Byzantine North Africa and they are discussed as part of the more general repertory of Byzantine fortifications. The unusual tower adjacent to the West Church is considered in the context of literary accounts. The article concludes by considering how the architecture and magnitude of the fortifications can allow a reassessment of the wider role of the city in the sixth and seventh century defences of Cyrenaica.
