Effect of Shallow Failure Mechanism on Interpretation of Ball Penetration Test in Non-Homogeneous Clay
Authors: Han C , Zhang Q , Liu J
Published: June 2024

Ball penetrometers are used to measure the undrained shear strength of clayey soils. When the ball penetrometer penetrates the soil from shallow to deep embedment, the flow mechanism of the soil around the ball evolves from the 'shallow cavity' mechanism to the 'deep full-flow mechanism. The bearing capacity factor of the ball is constant with the full-flow mechanism achieved. However, the bearing capacity factor of the ball at shallow embedment associated with the shallow failure mechanism is not a constant and depends on the geometry of the cavity behind the advancing ball. This study conducts large deformation finite-element analyses to model the penetration of the ball penetrometer in clayey soils. By setting a more realistic interface model employing the contact mechanics method, the ball-soil interaction in the non-homogeneous soil can be modelled. Parametric studies are conducted to investigate the effects of mudline strength, strength gradient, and unit weight of the soil on the variation of the bearing capacity factor of the ball at shallow embedment. Finally, an empirical model is proposed to calculate the transition penetration depths governing the transition from shallow to deep full-flow mechanism.
P-y Response in Porous Rock: Numerical Derivation With Experimental Validation
Authors: Riccio T , Previtali M , Ciantia M O , Brown M J
Published: June 2024

Design criteria for piles installed in soft rock have, until recently, been inadequate, relying on empirical design guidance based on limited field data. Design methods have recently been developed to encompass the complexities of axial pile design in chalk but are not yet extended to lateral pile design. Herein, the authors aim to investigate the lateral behavior of piles in a soft artificial rock through a physical and numerical experiment to develop a new p-y response; thereafter, comparing the results to existing lateral rock pile design approaches. Studies of the rock analogue material are undertaken using X-ray computed tomography to evaluate installation and loading effects. The numerical simulations are performed using PFEM and a bonded-material constitutive model for studying both installation and lateral behaviour.
Application of Axial Load Tests in the Netherlands to Offshore Pile Design
Authors: Duffy K , Gavin K G , de Lange D A , Korff M
Published: June 2024

This paper describes axial load tests on three full-scale driven precast piles in the Netherlands. The piles were founded in dense to very dense river-deposited sands, a soil that is widespread across the Dutch North Sea sector. The deposit is characterised by cone penetration test (CPT) tip resistances of up to 90 MPa and offers a detailed insight into pile response in realistic offshore conditions. Each test pile was incrementally loaded to failure under compression, while fibre optic sensors measured the changing deformation of the pile. The analysis and interpretation of the load test data focussed on how the three slender piles behaved at large shaft and base resistances. Notably, the piles mobilised base and shaft resistances greater than currently prescribed limiting resistances in design standards, thereby highlighting some overconservatism present when designing piles in dense sand.
Non-Vertical Spudcan Impacts on a Dense Sandy Seabed: Improving Design Through Centrifuge Modelling
Authors: O’Beirne C , Randolph M F , Bienen B , Chow S H
Published: June 2024

Bottom-fixed wind turbines are often installed from a mobile jack-up vessel which is supported on spudcan foundations while on location. During emplacement, the spudcans may impact the seabed at an angle resulting in large stresses transmitted to the leg-hull connections. It is difficult to predict these stresses, particularly for dense sandy seabeds where uncertainty remains regarding shallow penetration resistances developed during high shear rates and reduced drainage. This paper considers the problem through centrifuge modelling with a dense sand sample. A model spudcan was attached to a swinging' loading arm to simulate dynamic, non-vertical impacts with realistic trajectories. Impact velocities of 1-2 m/s were targeted by setting the spudcan into a free-fall swing where a MEMS accelerometer and Hall effect sensor captured the entire dynamic event. Bending and axial gauges allowed force components at seabed impact to be resolved, helping to address current design uncertainty with respect to peak impact forces and bearing resistance.
Generation of a General Cowden Clay Model (GCCM) Using a Data-Driven Method
Authors: Kamas I , Burd H J , Byrne B W , Suryasentana S K
Published: June 2024

Monopiles are the most widespread foundation option for offshore wind turbines. The PISA (pile soil analysis) joint industry research established a one-dimensional (1D) model for calculating the monotonic behaviour of laterally loaded monopiles by using a parametric equation to represent the soil reaction components. During the current PICASO project, a new data-driven method has been developed, as an alternative form of the PISA design model, in which Gaussian process regression (GPR) is employed to formulate the soil reaction curve data that are required to drive the 1D model to predict the monopile's monotonic behaviour. This paper presents a general Cowden clay model (GCCM) generated by using this data-driven method. The 1D model employing the GCCM can be used to predict the initial stiffness and ultimate capacity of piles embedded in homogenous glacial clay till soils within a range of different stress histories.

Published: June 2024

Plate anchors offer a cost-effective anchoring solution for offshore floating energy devices. This study aims to investigate the uplift capacity of horizontal plate anchors in dense sand using the critical state-based model NorSand implemented in finite element (FE) software Abaqus. Both drained and fully undrained simulations were conducted to study the effect of embedment depths on anchor capacity. The numerical results were validated against reported experimental data. The failure mechanisms of horizontal plate anchors in dense sand under drained and undrained conditions were investigated. Insights were also gained on the development of excess pore pressure around the anchor in the undrained simulations.
Back Analysis of PISA Pile Tests at Dunkirk Using a Practical Nor-Sand Model
Authors: Selby M , Zhou H , Liu T , Boylan N
Published: June 2024

It is typically challenging to model numerically soil-structure interaction problems in sandy soils with high accuracy. Difficulties include employing competent but practical soil constitutive models and dealing with issues associated with sample disturbance. In this paper, the Nor-Sand model is shown to be a promising candidate capable of overcoming these problems. The PISA pile tests performed at Dunkirk were selected as a case study. The ground conditions were reproduced by the Nor-sand model, and selected PISA lateral pile tests were back-analysed. A parametric study was performed by using both the parameters derived from laboratory tests on reconstituted samples and from in situ testing that captured the sand deposits long-term fabric and ageing effects. Recommendations are provided for achieving representative sand characterisation. It is emphasised that for numerical modelling, the most important steps are careful characterisation and parameterisation of the soil model, rather than the numerical modelling per se.
Impact of Dumping Operations at a Canyon Head on Turbidity Current Geohazard: Insights from a Project Development
Authors: Bolla Pittaluga M , Porcile G , Durante L , Pirmez C , Malgesini G , Wallerand R
Published: June 2024

In the framework of a liquified natural gas (LNG) project development, 16 million m3 of sediment will be dumped at the head of a submarine canyon. We investigate the ability of spring tides and monsoon storms to resuspend the dumped sediment and trigger turbidity currents (TCs) along the canyon. An integrated modelling is developed and validated against in-situ measurements to describe the dispersion of the dumped sediment, its subsequent erosion due to macro-tidal and storm-induced currents, the triggering and down-canyon evolution of TCs. Our results show that TCs can be triggered by both energetic spring tides and extreme storms after the dumping, indicating a potential yearly frequency of these flows. However, the first TCs can erode most of the fine-grained sediments, cleaning the canyon of the fuel for successive events. If confirmed by surveys of tidal erosion, these findings imply a limited risk of damage for the planned subsea infrastructures.
New 'Young Geographers' : Children's Cognitive Development Wayfaring Through the City Replica Project
Authors: Black Delfin Annabelle , Wang Wenjie
Published: June 2024

This paper examines how children relate an actual 3D environment to modular, loose parts in creating a 3D city replica with 2D embellishment. The main goals of the study were to examine children's creation of 3D replicas of immediate physical spaces in their educational setting and the cognitive development that is needed to support this type of play, as well as the cognitive benefits derived from engaging in symbolic 3D construction. Further, this paper explores children's 2D symbol use in the children's drawings and marks added to the surfaces of the loose parts during construction play. Framed by Vygotsky's sociocultural theory (1978), the qualitative research was conducted in a four-year-old classroom at a child development center in the southwest of the United States. Data was collected from photos, participants' narratives, and fieldwork and analyzed by the photovoice method through a developmental cognitive skills and abilities lens. We observed the interplay of the individual and society reflected in the children's understanding of their community's symbolic culture and approach to constructing a city replica. It was found that field trips of neighbourhood walks helped to establish children's perceptions of their community's symbolic culture before constructing the city model; further, children have dual representation abilities and can use their abstract reasoning skills in finalizing 3D constructions. Moreover, children used basic spatial skills, such as symbolic representation, position, location, perspective, scaling, direction, and navigation during the city replica 3D construction and in pretend play with the completed city replica product. Lastly, the seminal work of Mitchell (1991) is brought in to ground the results of the research project in the curriculum and pedagogy of early childhood.

Distribution of Radiation-Induced Defects in Quartz at the ACKIO Uranium Prospect, Athabasca Basin, Saskatchewan: Tracing Uranium-Bearing Fluids
Authors: Cheung Leo K. L. , Mackay Cameron , Sykes James , Pan Yuanming
Published: June 2024

Quartz grains from the ACKIO uranium prospect, located near the eastern margin of the Athabasca Basin, Saskatchewan, have been investigated using powder X-band electron paramagnetic resonance (EPR) spectroscopy. The EPR spectra of quartz separates from samples systematically collected from the Athabasca Supergroup sandstones and the underlying metamorphosed basement reveal a suite of silicon-vacancy hole centers, which were formed by the bombardment of alpha particles emitted from the radioactive decay of uranium, thorium, and their unstable progeny. The differences in EPR signal intensities of these hole centers indicate that quartz grains received different accumulative doses of alpha particle irradiation in different locations within the ACKIO prospect. For example, quartz extracted from a mineralized sample has the highest EPR signal intensity due to the presence of disseminated uraninite. For quartz sampled at distance from uranium mineralization, the elevated intensities of the silicon-vacancy hole centers most likely indicate a temporary source of radiation, such as ancient uranium-bearing fluids. The median EPR intensities of quartz from the basement rocks at ACKIO are an order of magnitude higher than those of its counterpart from the Athabasca sandstones. Also, the EPR intensities of quartz along the sandstone–basement contact at ACKIO differ by more than two orders of magnitude, suggesting limited migration of uranium-bearing fluids along this contact in the study area. Instead, anomalously high EPR intensities in quartz close to the sandstone–basement contact and elsewhere are restricted to fault gouges and brecciated areas, suggesting that they are the structural pathways for channelized migration of ancient uranium-bearing fluids. A three-dimensional distribution model of the EPR signal intensities has been constructed to define conduits for the migration of ancient uranium-bearing fluids at ACKIO and suggest favorable targets for further exploration. These findings demonstrate the power of EPR spectroscopy in delineating pathways of uranium-bearing fluids and predicting potential mineralization targets.

Published: June 2024

The optimization of the bleaching efficiency of acid-activated Ntezi bentonite was studied by reacting raw bentonite with different concentrations of hydrochloric acid solution for varying periods to activate it. The raw and activated samples were characterized using X-ray fluorescence. The activated samples were used to bleach palm oil and the effects of bleaching process variables were investigated using the Response Surface Methodology (RSM). Results of the analysis showed that the structure of the bentonite was altered by the acid activation and this increased the adsorptive capacity of the activated samples. The statistical analysis indicated that the main and quadratic effects of the bleaching process parameters were significant at the 95% confidence level. The optimum conditions were determined to be: reaction temperature 156.66°C; reaction time, 2.74 hours; adsorbent dosage, 5.93 g; adsorbent/oil ratio, 0.04 g/ml; and stirring speed, 411.62 rpm. Under these conditions, the optimum bleaching efficiency was determined to be 85.48%, which agreed with the experimental value of 86.07%. This study showed that Ntezi bentonite can be used as an effective adsorbent under optimized process conditions.
From the Nascent Earth to Ante-Cells Molecular Structures?
Authors: T Michel , D* Jacques
Published: June 2024

During its early youth, the Earth was the site of extremely violent processes. In particular, the energy of the impact of the planet Theia with the young Earth was such that the latter became entirely covered with a thick layer of molten magma, called the "magma ocean". On the now calmed Earth that we currently know, the objects classified as "living" by our sense organs are distinguished from those classified as "non-living" by two main characteristics: i) living objects have a completely original organic molecular constitution and ii) in contrast to non-living objects, which tend to equilibrate with the outside, living objects never reach equilibrium and are therefore "obligatory dynamical systems" out of equilibrium. It seems that the dynamic characteristic was acquired before the molecular characteristic for the genesis on Earth of the first living object(s). We propose that hypothetical "ante-cells" reached a "dynamic although inorganic" state on the nascent Earth, and then, that these ante-cells gradually transformed into real cells once the Earth had cooled sufficiently for organic molecules to appear there. The vestigial pentameric RNAs would mark this key moment when the ante-cells have begun to join the organic world.

Published: June 2024

Consumption of food contaminated with parasites pose a significant threat to public health particularly in underprivileged communities with inadequate access to sanitation and food safety practices. Unlike bacterial and viral infections, parasitic infections often develop slowly and are reported cause chronic health issues. However, due to extended incubation time, it is difficult to determine the source of the infection. The type and number of parasites in food, the temperature at which food is prepared and stored, as well as a person's immune system, all of these contribute significantly to the onset of parasitic infection. This mini-review focuses on common parasitic infections, their emergence with traditional and novel foods, transmission mechanisms, epidemiological trends, and effective prevention and control measures. Understanding these aspects is crucial for developing strategies to reduce the impact of foodborne parasitic infections on public health, particularly in vulnerable populations.
Social Media Communication Strategy of Al-Izzah Campus Da'wah Institute UIN North Sumatra in Optimizing the Spread of Islamic Values on Social Media

Published: June 2024

This research aims to investigate how the communication strategy of the Al-Izzah UIN North Sumatra Campus Da'wah Institute (LDK) maximises the dissemination of Islamic ideals on social media. The research employed a descriptive qualitative research method. Qualitative research methods employ scientific techniques to elucidate a phenomenon by comprehensively summarising data and facts using language, with respect to the subject of study. The data collecting methods employed were interviews and observations of dakwah content on the LDK Al-Izzah UINSU Instagram social media account. The research incorporates the theories of New media proposed by Pierre Levy, the impact of dakwah on social media, and communication methods utilising SWOT analysis. The primary findings of this study reveal the effectiveness of utilising distinctive and innovative dakwah content, such as humorous videos, to captivate and engage the audience in the dakwah message. Furthermore, the deficiency in disseminating dakwah content on social media stems from a scarcity of manpower and the utilisation of rudimentary instruments for making dakwah content, hence leading to subpar outcomes in the created dakwah video content. Furthermore, there are potential to disseminate Islamic ideals on social media platforms, particularly through the emerging trend of providing innovative and contemporary preaching content. Furthermore, the Al-Izzah Campus Da'wah Institute faces a hindrance in disseminating Islamic ideals on social media due to the removal of parts of their dakwah content on LDK Al-Izzah's social media platforms.

Fish meat is more susceptible to pathogen contamination than other protein-rich foodstuffs due to its high deterioration. Pseudomonas aeruginosa is considered one of the most common microbial strains responsible for the deterioration of fish and seafood products. the study's goals are to detecting virulence variables Pseudomonas aeruginosa and estimating the level of contamination in a fish sample, In this research, 120 fresh fish samples, gathered from a the local Diwaniyah city market local fish meat sample. including (60 marine fish and 60 common carp (Cyprinus carpio). The isolates were subjected to numerous biochemical, microbiological, and molecular analyses, and the results showed that about 26 samples were contaminated with Pseudomonas spp. performed on 21.6% of the total sample. Polymerase chain reaction (PCR) was used to amplify 539 bp, 511 bp, and 495 bp, for 16S DNA, Tox A, and Tox S respectively. A total of 21 Tox A genes were identified in 26 P. aeruginosa isolates, whereas the ToxS gene was detected in 17 of the same isolates. According to the results Pseudomonas aeruginosa isolated from fish samples contains multiple virulence factor genes, indicating high pathogenicity, which may affect consumer health because these variants exhibit the capability to increase the pathogenesis of the microorganisms with the severity of the infection and cause economic losses

Metabolites of oxygen are called reactive oxygen species (ROS). They are constantly synthesized by healthy cells are a consequence of aerobic respiration and are necessary for proper cellular function. These species (ROS) cause oxidative stress as a result of generation exceeding the capabilities of the antioxidant system to neutralize it. It is a bifurcating factor in controlling the reproductive system of females, as it can influence various physiological activities or contribute to infertility in females. The current review notes that several ovarian function processes, including reactive oxygen species, have a major impact on follicular formation, ovulation, and corpus luteum function. Scavenging mechanisms also occur. However, the review concentrates on the detrimental impact that elevated ROS production has on the female reproductive system. This review concludes that free radicals play a variety of roles in ovarian function and that excess has negative effects on the female reproductive system.

Chlamydia is an obligate intracellular Gram-negative organism that causes abortion, or "enzootic abortion of ewes", which is characterized by causing economic loss in sheep breeding. Chlamydia abortus spread could be stopped, and monitoring efforts could be more successful by gathering data on the condition of the disease. This ground-breaking study focused on the phylogenetic analysis and certain risk factors of Chlamydia abortus in ewes in Nineveh governorate, Iraq. 52 placenta samples were collected, representing 52 flocks (8660 ewes) who suffered from abortion in various Nineveh provincial locations between August 2022 and January 2023. Two local sequences were submitted to GenBank and assigned the accession numbers OR334580 and OR334581. The Chlamydia abortus 16S rRNA sequences were analyzed using the GenomeNet multiple sequence alignment tool (CLUSTALW), an online resource. After that, the sequences were compared to other Chlamydia abortus sequences that were accessible in the GenBank using NCBI BLAST (BLASTn) of NCBI. The Tamura-Nei model in the MEGA11 software program was used to create the phylogenetic trees. Results indicate that 15.38% (8/52) of the ewes had positive results for Chlamydia abortus, which was significantly affected by the increase in herd size and interspecies farming. Two sequences were put through individual sequence analysis, which revealed new Chlamydia abortus sequences, which were recorded for the first time in the governorate of Nineveh. We concluded that a higher risk of infection occurs in farms that contain more than 100 ewes and are mixed with other species of animals.

This present investigation was done for the Isolation and Molecular confirmation of Staphylococcus aureus from Bovine mastitis-infected cows in various Tamil Nadu, India locations. Two hundred milk samples, ranging from 15 to 20 ml, were collected aseptically from cows in farms in and around Tamil Nadu and surrounding areas after discarding the first few streaks of milk from 2021 to 2023. We used the CMT test to check the milk samples. Following a thorough mixing of the milk samples delivered to the laboratory, one loop containing the infected milk sample was plated on Nutrient agar and incubated at 37 ˚C for 18 to 24 hours. To identify the Staphylococcus aureus, the isolated bacterial colonies were preliminarily identified by Microscopic examination (Gram staining and Motility test), Plating in Selective medium (Mannitol Salt Agar) and Biochemical tests. The DNA of the bacteria was extracted and Polymerase Chain Reaction (PCR) was done to detect the presence of the nuc gene. Of the 200 milk samples obtained from nursing cows, 37.5 % were from Mastitis-positive animals; of these, 61.3 % were in the sub-clinical stage, while 38.7 % were in the clinical stage. Only 33 (16.5 %) of the 200 milk samples tested positive for Staphylococcus aureus. A total of 26 out of 75 animals (34.7 %) with Mastitis, and 7 out of 125 animals (5.6 %) without Mastitis. Fifteen (57.7 %) of the twenty-six Staphylococcus aureus isolates found in cows with mastitis were from clinical cases, whereas eleven (42.3%) were from sub-clinical cases. All of the Staphylococcus aureus isolates examined contained the 279 bp nuc gene, according to the conventional PCR findings. In conclusion, the research has shown that sub-clinical mastitis is more common than clinical mastitis and that Staphylococcus aureus was substantially more often isolated from mastitis milk, particularly in clinical instances.

Introdução: A Psicologia Forense, enquanto subárea da Psicologia Jurídica, tem despertado crescente interesse entre os públicos que consomem seriados e filmes sobre investigação criminal, especialmente aqueles que retratam casos de psicopatas famosos, frequentemente presos com o auxílio de Psicólogos Forenses. No entanto, esse ramo de estudo apresenta uma prática diversificada, e esses profissionais podem atuar em diferentes instituições jurídicas, particularmente aquelas onde adolescentes cumprem medidas socioeducativas. Objetivo: Este estudo visou investigar a aplicabilidade da Psicologia Forense nos Centros Socioeducativos, com o objetivo de esclarecer dúvidas sobre a contribuição dessa especialidade para a ressocialização de jovens em conflito com a lei. Método: Adotou-se uma abordagem qualitativa, utilizando a metodologia de revisão integrativa da literatura. Foram exploradas produções disponíveis no Google Acadêmico, SCIELO e livros específicos da área. Resultados: Identificou-se que a atuação desses profissionais vai além da produção de documentos psicológicos que auxiliam os juízes no veredito de um caso, incluindo o desenvolvimento de programas psicoeducativos e terapêuticos que envolvem os jovens, suas famílias e a comunidade que os acolherá após o cumprimento de suas sentenças. Conclusões: Concluiu-se que a atuação do Psicólogo Forense nos Centros Socioeducativos é ampla e essencial para a ressocialização de adolescentes em conflito com a lei, uma vez que os programas desenvolvidos por esses profissionais ajudam na reabilitação e integração deles com família e comunidade.
