Abstract:
Black Canadian writer Wayde Compton’s short story collection The Outer Harbour (2015) is located in the Afroperiphery of British Columbia which stands as a ‘contact zone’ that enables the alliances between Black and Indigenous peoples and also establishes a fecund ground of possibilities to emphasize the way in which cross-ethnic coalitions and representations reconsider imperial encounters previously ignored. The stories participate in the recent turn in Indigenous studies towards kinship and cross-ethnicity to map out the connected and shared itineraries of Black and Indigenous peoples and re-read Indigeneity in interaction. At the same time, the stories offer a fresh way to revisit Indigeneity in Canada through the collaborative lens and perspective of the Afroperipheral reality. In doing so, they contribute to calling attention to current cross-ethnic struggles for Indigenous rights and sovereignty in Canada that rely on kinship and ethnic alliances to keep on interrogating the shortcomings of the nation’s multiculturalism.

Abstract:
Benthic communities form an important component of the marine food chain. Their occurrence also provides information on the health of the ecosystem. A study was carried out to understand the distribution and abundance of macrobenthos along with sediment characteristics and physicochemical parameters in Visakhapatnam Harbour, a major port along the east coast of India. In all 84 macrobenthic taxa were reported from the port area of which 60 were polychaetes and 24 were other invertebrate taxa. Our observations revealed an increase in the number of polychaete species observed over the last 20 years from this region. An earlier study reported 38 polychaete species in 1975 and a year later the number of polychaete species reported was 12, indicating an increase in the number of polychaete species in the present study by about 150%. The macrobenthic abundance and dominance of species varied with the seasons. Pre-monsoon was dominated by Cirratulus sp., during monsoon tanaids were dominant indicating a seasonal shift in the occurrence and dominance of macrobenthos. During post-monsoon, Cossura coasta was dominant followed by Nephtys dibranchis and amphipods. Sediment characteristics (sand, silt and clay), organic carbon and dissolved oxygen were the important factors influencing the abundance and species diversity. The abundance of macrobenthic forms also varied with inner and outer harbour region. Higher species diversity was observed in the outer harbour suggesting the outer harbour has semi-polluted conditions such as higher dissolved oxygen (DO) and salinity, low nutrients (nitrite, nitrate and silicate) and low organic carbon in the sediment.

Abstract:
This study examines the circulation, flushing time and hydrodynamic connectivity in Halifax Harbour based on three-dimensional currents produced by a multi-nested coastal ocean circulation modelling system. The time-mean currents produced by the modelling system feature two-layer estuarine circulation with a seaward flow in the upper layer and a landward flow in the lower layer in the Harbour. The hydrodynamics in the Harbour are also affected significantly by tides and wind forcing. Based on numerical passive tracer experiments, the estimated e-folding flushing time is about 40 and 90 days in the upper and the entire Bedford Basin, respectively. By comparison, the flushing time is about 2–5 days over the Inner and Outer Harbour, and only about 1 day in the Narrows. Analysis of passive particle trajectories carried by the model currents demonstrates that movements of particles in the Harbour are strongly affected by tidal and storm-induced currents. Hydrodynamic connectivity in the study region is also quantified in terms of a connectivity matrix calculated from particle trajectories.

Abstract:
The majority of proteins within mitochondria are synthesized on cytosolic ribosomes and imported into the organelles. Protein complexes in the mitochondrial outer membrane harbour both the receptors that recognize these preproteins, and a translocation pore. These "receptor complexes" are the entry points for most preproteins, which are subsequently targeted to their final submitochondrial locations. The outer membrane complexes cooperate with the import machinery of the inner membrane to target preproteins to the inner membrane itself, the matrix, or, in some cases, to the intermembrane space. In isolated outer membranes, these complexes are capable of accurately importing preproteins destined for the outer membrane. Our current understanding of the composition, function, and biogenesis of these outer membrane receptor complexes is the focus of this article. Key words: mitochondria, outer membrane, protein import, receptors.

Abstract:
A summer-long monitoring programme investigated mechanisms controlling near-bottom dissolved oxygen (DO) concentrations in New Bedford Outer Harbor, a shallow embayment on the southern Massachusetts coast that receives discharge from a 1.3 m3 s-1 municipal sewage outfall. Continuously recording meters and hydrographic cruises measured DO, temperature, salinity, meteorology, waves and/or currents. The programme quantified the magnitude, spatial extent and duration of oxygen undersaturation in the bottom waters. Summer stratification of New Bedford Outer Harbor reduced reaeration of the bottom waters. Depletion of near-bottom DO was strongly correlated with the presence and duration (though not intensity) of stratification. Stratification is typically thermal, a result of seasonal warming of the water surface, although it can become enhanced (and somewhat salinity driven) owing to the influx of cold saline bottom water following major storm events. Destratification is caused by high wind speed or a drop in 24-h average air temperatures below the water temperature. The decrease in DO concentrations when the water column is stratified is directly related to local sediment oxygen demand. In general, DO dynamics were found to be local and fundamentally one dimensional.

Abstract:
Rock pools provide a range of ecological niches that can support diverse assemblages on rocky shores. As intertidal shores are increasingly lost to developments, understanding the drivers of diversity in rock pools is important for the conservation and construction of these key habitats. In this study we investigated relationships between physical characteristics of rock pools and their biota in an urban estuary. We sampled the biota every 6 weeks for 1 year at sites in the inner and outer zones of Sydney Harbour. In the well-flushed and exposed outer zone, sessile and mobile taxa richness was positively related to rock pool width, whereas only mobile taxa richness was related to depth and volume. In the more urbanised and less exposed inner zone, mobile taxa richness was positively related to rock pool width and volume. In both zones, sessile taxa richness decreased with increasing height on shore. Our results suggest that the biodiversity of intertidal rock pools varies depending on their position in Sydney Harbour and the available species pool. Therefore, restoration efforts should consider rock pool size parameters and local environmental conditions, including location, so designs can be optimised to maximise species diversity in these pools.

Abstract:
INTRODUCTIONPresence of O-group bass, Dicentrarchus labrax (L.), has been recorded for a number of estuaries and tidal backwaters in the south of the United Kingdom, including the tidal Thames (Wheeler, 1979), the outer Thames at Southend (Murie, 1903), the Medway (Van den Broek, 1979), Langstone Harbour (Reay, 1973), the Dart (Dando & Demir, 1985), and the Tamar (Hartley, 1940). The author has found them, additionally, in Chichester Harbour and in the Cuckmere (Sussex), Teign and Tavy estuaries. Correspondents have reported them from the estuaries of the Blackwater (Cox), Crouch (Wiggins), Lynher (Gee) and Fal (Melhuish); also from the Fleet backwater in Dorset (Fear). It may be inferred that all estuaries and tidal backwaters on the south and south-east coasts of the U.K. constitute bass nurseries, in some degree.*

Three years ago, the Taichung Harbor Bureau was proposing a feasibility study on the outer-harbor development in Taichung Harbor. In January 2011, the final report was completed and some outer harbor developing projects were proposed. However, these proposals only take into account the ship-handling and business aspects, not on the environmental aspect. Since the shape of Taichung Port is a long, narrow and semi-enclosed form and it is not easy for the pollutants to dissipate, especially in the southern part of the port. If the outer harbor project were going to proceed, the water pollution problems will be more complicated. In this study, a two-dimensional numerical model was utilized to simulate the effect of water flow pattern and pollution dispersion due to various outer harbor developing projects. Two kinds of indicators, both Index of Enhancement (IE) and Integrated Index of Risk (IIR) were examed to evaluate the impact of water pollution in Taichung Harbor. So as to find better outer harbor developing projects. The results of IE evaluation showed that the water pollution in the C-type port is slighter than those in the O-type port. On the other hand, the results of IIR evaluation showed that pollution risk in the O-type port is higher than those in the O-type port. It concluded that the C-type port was a better choice compared to the O-type port. It also suggested that a previous evaluation of IE and IIR due to any developing project was very important in preventing improper development.

Abstract:
AbstractThe main function of the bones is the internal support and the storage of inorganic ions. Bones consist of the outer compact bone that harbors the inner cancellous bone and the bone marrow. Main cells are the bone-building osteoblasts, the bone-supporting osteocytes, and the bone-resorbing osteoclasts. All the cell lines communicate via the OPG RANK RANKL system.The term osteomyelitis describes inflammation of all bone structures. Depending on the clinical presentation and the cause triggering the osteomyelitis, it can be classified into acute osteomyelitis that is called secondary chronic osteomyelitis after a time span of more than 4 weeks. In general, an odontogenic infection is responsible whereas the trigger of the secondary chronic osteomyelitis is unknown. Symptoms of acute osteomyelitis are fever, listlessness, swelling, pain, reddishness, trismus, tooth mobility, pus, and paresthesia. In the secondary chronic stadium, the swelling is less prominent and a periosteal reaction, sequester formation, and fistulas can occur. The primary chronic osteomyelitis often has few and not very prominent symptoms with a nonsuppurative inflammation. Therapy consists of antibacterial mouth rinses and antibiotics to different surgical procedures.Osteoradionecrosis and medication-associated osteonecrosis are subentities where the radiation or a medication alters the bone biology and subsequently causes osteonecrosis of the affected bones.

Abstract:
This chapter returns to the beginning of the book by seeking to explain how Chicago came to have the glorious lakefront we see today, with its parks, its Lake Shore Drive, its clean shoreline free of rotting docks and industrial facilities. It examines how Chicago, a city long dominated by private enterprise, ended up with such a relatively large quotient of public rights on its lakefront. The chapter then ventures to offer some thoughts to the questions, and recounts Chicago's specific factors like the absence of an outer harbor, the successful campaign of the Michigan Avenue property owners, the decision of the Illinois Supreme Court in the Revell cases to eliminate the common-law right of riparian owners to wharf out into the lake, and the creation of park districts as semiautonomous local government entities. It introduces some individuals such as Alonzo Mack, Ellis Chesbrough, Montgomery Ward, Daniel Burnham, Edward Brown and their influence on the Chicago lakefront. In emphasizing these Chicago-specific factors and the role of particular individuals, the chapter analyses the four broad categories of influence beyond the Chicago experience: the magnetic attraction of a large body of water such as Lake Michigan, the changing state of technology, the growth in the size and effectiveness of government institutions and the law.

Abstract:
The concept of ecotourism in protected areas and their implications for the conservation of flora and fauna are of global significance. Ecotourism is not only for suitable practice of tourism in protected areas as it deals with environmental conservation, but also supports local communities. The Himalaya in present times harbors a good increase of ecotourism in protected areas like Rajaji tiger reserve, Nanda Devi Biosphere reserve, Corbett National park, Kedarnath wildlife sanctuary, etc. Efforts done by state government in building tourism state have promoted the tourism industry in general. This chapter will explore the potential of ecotourism in protected areas and the local people's perceptions towards the local tourism, conservation of wildlife and substitutes for their livelihood. Additionally, it will explore potential sites already developed or can be developed for increasing options for enhancing ecotourism, providing information about various tools, which can attract the tourists from various disciplines.

Abstract:
In the process of exploitation of oil and gas in deeper water and ultra deep water, the problem of how to guarantee the effective support for work boats is inevitable. This is especially vital for the oilfields in harsh environment several hundreds of nautical miles away from the terrestrial supply center. In order to solve logistic support problem, an ultra large floating system concept arising from the intermediate base was put forward with functions of material reserves, refuge harbor for work boats, and landing pad for helicopters. The ring ultra large floating system with outer diameter of 400 m comprises eight modules and each module has four columns with heavy draft. The wave chamber composed of horizontal perforated double-layer breakwaters is positioned close to the water plane to reduce the reflection and dynamic pressures on the vertical hull. The applicable water depth can exceed 2000 m. This paper describes a physical test for the purpose of evaluating the various functions of ULFS concept.

Abstract:
In order to reduce the direct wave impact, coastal and offshore structures are often constructed with one or more perforated layers. Several permeable breakwaters and docks have been deployed in coastal protection measures to reduce direct impact due to encountered wave loads and to reduce wave reflection in front of these structures as well; compared with the traditional ones, such structural forms are found to be more economical. Such structures result in lesser surface fluctuation in harbours due to the low reflection, which is vital for loading and unloading of ships. Deploying permeable breakwaters posses other advantages namely: i) increasing water circulation; ii) retaining water quality and iii) enhances coastal protection. Emerged and submerged perforated cylindrical structures reduce wave-structure interactions and scouring problems considerably, but their use on floating structures is scarce in the literature. This study is focused on detailed experimental investigations carried out on impermeable inner cylinder encompassed by a larger outer cylinder with perforatios along its length. By varying the porosity and perforatio diameter, their influence on the hydrodynamic response of the cylindrical member is highlighted through the current study. The conclusions on the comparison of forces in the cylinder with and without perforated cylinder coverage are presented.

Abstract:
It is well known that soil plugging inside tubular steel piles will only appear in rather small diameter piles during impact driving. Therefore, large open ended steel piles, which are often used for the fixation of offshore buildings, such as wind farms, are highly unlikely to develop an internal soil plug. To take advantage of a soil plug, where a significant rise in the piles’ bearing capacity generally appears, a large diameter pipe-pile with an inner steel ring was designed by the third author. The location of the steel ring was determined by the soil formation in situ. To avoid increasing pile driving energy, the internal ring should dip into dense soil conditions only for the last few decimeters of driving. In October 2010, a full scale test was performed in the harbor of Hamburg, using two tubular piles with an outer diameter of 1220 mm. One pile was equipped with an inner steel ring as described above. The second pile was a typical tubular pile without any attached systems. To better compare the results, both piles were driven next to each other. Both piles were equipped with internal total stress and pore water pressure sensors at the pile tip to investigate the radial stress development during and after installation. Acceleration and strain at the pile head were measured to predict the bearing capacity. Using the numerical analysis program CAPWAP (Case Pile Wave Analysis Program) [15], the distribution of shaft and toe friction can be determined additionally. Furthermore, the internal soil movement was surveyed during driving. The results of the measurements showed, that when using an inner steel ring, a significant rise in internal radial stresses and the piles’ bearing capacity occurs. To better understand the stress development inside and outside the two investigated piles during driving, a numerical back-calculation of the recorded measurements was performed. The results of the full scale and numerical simulations, with a particular focus on the use of an internal steel ring to force the soil to plug behavior in large diameter pipe piles, is presented in the following paper.

Abstract:
The present tests are conducted in the new Québec Coastal Physics Laboratory, Canada. The flume has a depth and a width of 5 m and is 120 m long. This paper presents large scale experiments of water wave impact on a vertical wall following wave runup on a mixed sand-gravel-cobble beach. This present study is concerned with advancing knowledge on rapidly varying pressure magnitude and distributions on different types of sea/river/harbor walls. Protection against extreme events and subsequent coastal erosion is a key theme of application. Herein is presented preliminary test series which has focus on forces on vertical walls. Specifically, 27 pressure sensors are mounted on the vertical wall with a total test area of 1.2 m wide and 2.4 m high and is a stiffened aluminum plate. The outer regions of the wall are made of steel to span the entire width of the tank. The wall is designed to behave as a rigid plate. The geometric model to full scale is about 1:4. The incoming waves evolve on a flat bed to climb the final 25 m on a beach with slope with constant slope of 1:10. A small regular wave train forms the basis for investigations of force patterns on the wall. Herein, our preliminary findings reported are based on selected 6 test series (18 impacts out of 150 impacts). In general, wall pressures greater than 1 MPa and 10 m run-up are easily developed even with moderate amplitude waves at the inlet. We will discuss some details of the underlying mechanism of various types of breaking and impact on the wall. The peak pressure identified on the wall with the mixed gravel beach surface was 1.23 million N/m2 occurring in 0.2 milli seconds. It was cuased by a plunging breaker with a relatively large air pocket (∼0.11 m2). It was further identified that the maximum pressure on the wall does not necessarily give the maximum jet velocity (equivalent to vertical force considered in design of on parapets). They are independent quantities in these very random rapid processes. The maximum jet velocity was in the order of 35 m/s but could higher on a different beach surface. Further, it was found that the maximum waves are not necessarily the most critical ones as the waves break and therefore dissipates its energy before reaching the wall. A plunging breaker with a relatively large airpocket with a crest tip located at the top part of the wall resulted in max. peak wall pressure. One impact case caused a near simultaneous double peak pressure generated by a plunging breaker with two relatively small airpockets (0.003 m2 and 0.01 m2). This was the impact case responsible for the max. vertical jet velocity. We further found that the max. peak water pressure of the plunging breakers had a similar order of magnitude as the max. pressure within an air pocket.
