Abstract:

Impact loads generated from the dynamic effect of passing trains can exacerbate the degradation level of ballast aggregate of railway track. To diminish the induced impact loads, the use of crumb rubber (CR) in the ballast course is characterized as a well-established procedure related to the modification of utilized material. Nonetheless, more in-depth assessments of size and percentage of CR particles combined with ballast aggregate are still required. The present study evaluates the influence of size and content of CR particles used for degradation reduction of ballast aggregate subjected t

Abstract:

A long-term issue that has hampered the efficient operation of heavy-haul tracks is the migration of fluidized fines from the shallow soft subgrade to the overlying ballast, i.e., mud pumping. This paper presents a series of undrained cyclic triaxial tests where realistic cyclic loading conditions were simulated at low confining pressure that is typical of shallow subgrade beneath a ballast track. Subgrade soil specimens with a low-plasticity index collected from a field site with recent history of mud pumping were tested at frequencies from 1.0 to 5.0 Hz and a cyclic stress ratio (CSR) from 0

To explore the initial orientation effect of ballast assembly on the reinforcement performance of the geogrid reinforced ballast, particles with random orientation and five prescribed rotational orientations were developed through particle flow code (PFC3D).

Furthermore, the mechanical responses such as pullout force, distribution of axial force, displacement vectors, force chain, and mesoscopic fabric were discussed.

Abstract The ballast layer is part of the conventional railway track structure widely used in Indonesia due to its ease of maintenance, construction simplicity, and lower costs compared to slab track technology. This study models four types of test specimens, including the use of scrap tire rubber and bitumen materials. The scrap tire rubber and bitumen were added at proportions of 10% and 3%, respectively, using a compression test method to measure deformation, abrasion, and elastic modulus.

Abstract:

New observations of non-indigenous species (NIS) in coastal waters, such as the Gulf of Cadiz (Spain) have increased since 1980 and more or less exponentially in the last five years. Ballast water has become the most significant pathway for unintentional introductions of NIS into marine ecosystems. For example, the marine larvae of crustacean decapods that inhabit the water column could be transported in ballast water. Although elevated concentrations of metals are toxic to many marine organisms, some of them have evolved effective detoxification, or avoidance mechanisms making it possible to

Abstract:

Construction industry relies heavily on conventional material such as cement, sand and gravel for the production of concrete The river sand and gravels which are most commonly used as fine aggregates and coarse aggregates respectively in the production of concrete, poses the problem of acute shortage in many areas, whose continued use has started posing serious problem with respect to its availability, cost and environmental impact. Attempt is being made in this project to use the locally available waste materials to replace the river sand and gravels to produce light weight and low cost concr

Five individuals of Smith's cardinalfish Jaydia smithi were collected from Ibn-Hani area, Lattakia, Syria on the eastern coast of the Mediterranean Sea. Their morphometric and meristic characteristics are reported. There are several factors which assisted this specimen to reach this area of the Mediterranean; some of these factors might be the marine environment changes and the ballast water. This study reports that Smith's cardinalfish Jaydia smithi, a member of Lessepsian species was found in Syrian marine waters for the first time.

AbstractThe Palearctic species Amara communis (Panzer) and Bembidion femoratum Sturm were both first reported from North America in 1992. Since that time a sizeable number of additional specimens of both species have been found, which substantially expands their known range on the continent. These records are summarized herein. The possible modes of introduction of both species are discussed within the context of other introduced insects, particularly those first found in Atlantic Canada. In the case of A. communis, the many coastal localities where it occurs would seem to indicate that it was

Its distribution was restricted to the areas around Al-Sindibad Island and Al-Kornish in waters with temperatures between 27-28°C and salinities less than 4.1‰. A larger number of specimens was collected in August 2012 around Al-Sindibad Island, 134 specimens/m3, and in July 2013 around Al-Kornish, 378 specimens/m3 in waters of comparable temperatures and salinities.

Marine species are usually transported from one area to another by the ballast water used to provide safe operation for vessels. After entering a new environment, they may cause damage to the local ecosystem, leading to the disruptions of the entire marine ecosystem, and seriously affecting not only biodiversity but also several industries such as fishing and aquaculture. Therefore, the United Nations (UN) considers the presence of non-indigenous oceanic species to be one of the top four serious threats to the global environment; and, how to effectively control the non-indigenous aquatic speci

In August 2021, two specimens of invasive oligochaete of tropical origin Branchiura sowerbyi were found in the Sheksna reservoir of the Vologda region (59°45ʹ21ʺN, 38°21ʹ28ʺE). For today, this is the northernmost finding of this species. Probably, this species penetrated with the ballast waters from the Don River lower course through the Volgo-Don canal and the Volgo-Baltic waterway. The temperature regime of the water bodies of the Vologda region allows reproduction of this oligohaeta.

U.S. regulations controlling the discharge of ballast from all vessels entering from outside the Exclusive Economic Zone into the Great Lakes went into effect in early 1993 and are enforced by the United States Coast Guard, with active assistance from the Canadians and the Seaway authorities. The Great Lakes are a unique, valuable, and sensitive resource which have already suffered significant damage from nonindigenous species and are

The establishment of marine non-indigenous species (NIS) in new locations can degrade environmental, socio-cultural, and economic values. Vessels arriving from international waters are the main pathway for the entry of marine NIS, via exposure due to ballast water discharge (hereafter, ballast discharge) and biofouling. We developed a systematic statistical likelihood-based methodology to investigate port-level marine NIS propagule pressure from ballast discharge and biofouling exposure using a combination of techniques, namely k-Nearest-Neighbour and random forest algorithms.

The purpose of this paper is to present a quantitative risk assessment applied to a model port, the Port of Arzew in Algeria, and based on an analysis of this port’s shipping traffic. Design/methodology/approach – The risk assessment for introduction of invasive species is interpreted in the form of a probabilistic process, with a combination of two probabilities. The first probability is related to the ability of a species to arrive to the destination (recipient port), depending on the q

Abstract:

Mixed-species assemblages are often unintentionally introduced into new ecosystems. Analysing how assemblage structure varies during transport may provide insights into how introduction risk changes before propagules are released. Characterization of introduction risk is typically based on assessments of colonization pressure (CP, the number of species transported) and total propagule pressure (total PP, the total abundance of propagules released) associated with an invasion vector. Generally, invasion potential following introduction increases with greater CP or total PP. Here, we extend thes
