Authors: Kirton Roxane , Sandford Imogen , Raffan Eleanor , Hallsworth Sarah , Burman Oliver H. P. , Morgan Ruth
Published: June 2024

Background: Equine obesity is a growing concern, much of the
current management advice centres on dietary restrictions, including the
removal or limitation of grazing. Little is known about the
effectiveness and impact of this approach on the overall welfare of the
horse. Objective: This study investigates the impact of two
commonly used grazing systems advocated for the control of weight – the
‘strip-grazing’ system and the ‘track’ system - on the behaviour and
welfare of outdoor living ponies. Study design: A
within-subject cross-over experimental design was used with four groups
of pasture kept ponies experiencing each system for 4 weeks in a random
order. Methods: Time budgets and behavioural indicators of
welfare were measured using 24-hour electronic surveillance,
morphometric parameters including weight, body condition score and
cresty neck score were measured weekly and activity levels were tracked
using GPS tracking units. Results: Ponies moved more (median
(IQR), track: 3.23% (2.08%), strip: 2.02% (0.90%); P = 0.001) and
travelled a greater distance in 24-hour period (median (IQR), track:
7013.47m (1761.49m), strip: 5331.91m (494.16m); P < 0.001) and
engaged in less overt agonistic behaviour on the track system compared
with the strip system (median IQR; track: 0.14 (0.30), strip: 0.21
(0.37) P = 0.02). Main Limitations: A relatively short time
period of exposure to each grazing system. Conclusions: Track
systems resulted in a significant increase in ambulatory behaviour
compared with the strip system. Increased levels of agonistic
interactions on the strip system maybe the result of perceived reduction
of space or a spatial concentration of resources compared to the track
system, although the actual accessible area was the same. These results
suggest that there may be physical health benefits to the track system
as the ponies engaged in more voluntary low intensity exercise as well
as improvements to overall welfare.

Published: June 2024

Within the field of human-computer interaction, data gloves play an
essential role in establishing a connection between virtual and physical
environments for the realization of digital human. To enhance the
credibility of human-virtual hand interactions, we aim to develop a
system incorporating a data glove-embedded technology. Our proposed
system collects a wide range of information (temperature, bending, and
pressure of fingers) that arise during natural interactions and
afterwards reproduce them within the virtual environment. Furthermore,
we implement a novel traversal polling technique to facilitate the
streamlined aggregation of multi-channel sensors. This mitigates the
hardware complexity of the embedded system. The experimental results
indicate that the data glove demonstrates a high degree of precision in
acquiring real-time hand interaction information, as well as effectively
displaying hand posture in real-time using Unity3D. The data glove’s
lightweight and compact design facilitates its versatile utilization in
virtual reality interactions.
SADNet: Generating Immersive Virtual Reality Avatars by Real-time Monocular Pose Estimation

Published: June 2024

Generating immersive virtual reality avatars is a challenging task in
VR/AR applications, which maps physical human body poses to avatars in
virtual scenes for an immersive user experience. However, most existing
work is time-consuming and limited by datasets, which does not satisfy
immersive and real-time requirements of VR systems. In this paper, we
aim to generate 3D real-time virtual reality avatars based on a
monocular camera to solve these problems. Specifically, we first design
a self-attention distillation network (SADNet) for effective human pose
estimation, which is guided by a pre-trained teacher. Secondly, we
propose a lightweight pose mapping method for human avatars that
utilizes the camera model to map 2D poses to 3D avatar keypoints,
generating real-time human avatars with pose consistency. Finally, we
integrate our framework into a VR system, displaying generated 3D
pose-driven avatars on Helmet-Mounted Display devices for an immersive
user experience. We evaluate SADNet on two publicly available datasets.
Experimental results show that SADNet achieves a state-of-the-art
trade-off between speed and accuracy. In addition, we conducted a user
experience study on the performance and immersion of virtual reality
avatars. Results show that pose-driven 3D human avatars generated by our
method are smooth and attractive.

Published: June 2024

Objective: To examine the utilization of biologics during pregnancy and
6 months thereafter among patients with pre-conception biologic use.
Design: This is a retrospective cohort study Population or sample:
Pregnant individuals with an autoimmune condition and prior biologic
use. Methods: We used Merative® MarketScan® Research Databases to
identify pregnancies with one of the following conditions: inflammatory
bowel disease (IBD), rheumatoid arthritis (RA), psoriatic arthritis
(PsA), multiple sclerosis (MS), ankylosing spondylitis (AS), systemic
lupus erythematosus (SLE), or Juvenile Idiopathic Arthritis (JIA).
Pregnancies were included if they had used a biologic 6 months before
conception. Main Outcome Measures: Proportion of pregnancies with
biologic use at each pregnancy trimester, association between biologic
discontinuation and individual AID. Results: Our study included 3,026
pregnancies. Overall, biologic utilization declined during pregnancy,
with 65.2%, 52.5%, and 50.7% in the first, second, and third
trimester respectively. Maternal age- and conception year-adjusted odds
ratios for discontinuation in pregnancies with live deliveries was 12.9
(95% CI=6.3-26.3) for SLE, and 7.5 (95% CI = 5.56 – 10.14) for PsA
when compared to IBD. A higher proportion of live deliveries were
observed in pregnancies with IBD who continued biologic use (70.9% vs
51.7%) while persons with PsA (63.37% vs 68.1%), AS (60.0% vs
67.4%), and SLE (42.9% vs 71.9%) had lower proportion of live births.
Conclusion: Biologic utilization declined during pregnancy in patients
with AID and pre-conception biologic use with notable variations in
discontinuation and pregnancy outcomes observed among AID conditions.
Studies evaluating the risks and benefits of biologics specific to
autoimmune diseases during pregnancy are warranted.

Published: June 2024

In the current industrial era 4.0, the development of information technology has influenced all aspects of people's lives, including implementing government duties. One area that is also affected by advances in information technology is the land sector. The enactment of ATR/BPN Ministerial Regulation No.1 of 2021 and PP No. 18 of 2021 is a concrete manifestation of the use of developments in information technology in the land sector. Implementing land registration through an electronic system is expected to benefit the community, especially in terms of guaranteeing legal certainty. However, in its implementation, it turns out that various problems are still found, one of which is the neglect of the principles in land registration, namely the principle of security. The principle of security requires that land registration be carried out carefully and meticulously to guarantee legal certainty for holders of land rights. In this research, we will examine the application of the principle of security in electronic land registration to ensure legal certainty for the community. Using the normative juridical approach and analytical descriptive method, it can be said that the implementation of the principle of security in land registration via an electronic system that has been carried out by the Land Office has not been optimal. This can be seen from the many disputes and cases in the land sector that are still occurring and of course they are detrimental to society.

Authors: Mau Ellon Belwan Cornelius , Rafael Tontji Christian
Published: June 2024

Divorce not only entails property division but also raises significant concerns regarding child custody. Courts often intervene to determine which parent is better suited to care for the child after divorce. This research aims to explore the legal implications of divorce on child custody rights and understand the factors influencing custody decisions between fathers and mothers, both individually and jointly. Employing descriptive analysis with a normative approach, the study utilizes secondary data from primary, secondary, and tertiary legal sources. Findings suggest that divorce can result in the loss of child custody rights due to neglect of parental obligations and immoral behavior, which may have contributed to the divorce. Additionally, judges consider various factors in determining custody, including the child's welfare, emotional connection with parents, and parental responsibilities. Factors such as parental presence in the child's life, financial support, and emotional interactions with the child influence custody decisions. Therefore, it is recommended that parents maintain positive relationships with their children, prioritize family unity, and actively fulfill their duties in providing protection, affection, and proper education.

Published: June 2024

Leveraging solar energy will bring about a notable change in the fundamental production and use of power, and the parameters to achieve success in this area must be forecasted to aid steady production. This work entailed the use of advanced predictive machine learning models for optimal power output, reduced uncertainty, optimal resource planning, and a notably high degree of alignment with peak demands for energy for efficient power production from solar radiations. Models were generated by employing machine learning algorithms for data evaluation. The direct in-plane irradiance has the strongest correlation (1.00) with PV output, according to the results. Additionally, it indicated that the value of R2: 0.999567 of the Random Forest Regression was higher than all other regression models and the least Mean Squared Error (MSE) and Mean Absolute Error (MAE), 17.130680 and 2.28139, respectively. On the other hand, the Linear Regression’s Mean Squared Error (MSE), R2, and Mean Absolute Error (MAE) values are, respectively, 20.645271, 0.999478, and 3.16270. Random Forest Regression is a stronger forecasting model because of its higher R2 value, which also helps to explain variations in PV power output.

Authors: Ali Madhloom Tahseen , Ismael Murtada A.
Published: June 2024

Reactive powder concrete (RPC) is a new kind of concrete technique that has been enhanced and improved in recent decades which showing superior performance on structural systems. This paper shows experimental research to study the structural performance of reactive powder reinforced concrete one-way slabs in static loading by applying two symmetric loads and simply support type. In the present investigation, five RPC one-way slabs designed, casted and tested. All the slabs were similar in the length and the width (980x400mm), also in the properties of materials and their proportions, but different in thickness and the ratios of main reinforcement. They were cast into two groups; the first group had three values of longitudinal reinforcement proportions (ρw): 0.0036, 0.0048, and 0.0060, respectively, and the second group included three values of slab thickness: 40 mm, 60 mm, and 80 mm, respectively. Experimentally, it has been noticed that the ductility and flexural behaviour of RPC one-way slabs are considerably affected by increasing slab thickness but influence of longitudinal reinforcement less significant. The results of specimen testing indicated that increasing main steel reinforcement proportion from 0.0036 to 0.0048 and to 0.0060 led to an increase in the first cracking load test with a value of (19.05%, 42.86%), respectively, an increase in the ultimate load test with a value of (21%, 40.91%) respectively, and the value of ultimate mid-span deflection increased from 17.78% to 28.98%. The test results also revealed that the increase in thickness of slabs from 40mm to 60mm and then to 80mm led to an increase in the first cracking load test with a value of (166%, 240%), respectively, increase the ultimate load by (104.06%, 234.71%), respectively, and the value of ultimate mid-span deflection decreased from 36.82% to 58.26.
Numerical Study of Soil-Retaining Wall Behavior Subject to Machine Foundations Loads
Authors: M. Hassan Fatima , A. Zakraia Waad
Published: June 2024

A retaining wall was practically developed to provide lateral support for soil, and it is widely used in underground projects, highway barriers, and mines as well as for aesthetic considerations and slope stabilization. This type of earth structure member can carry machine foundation load simultaneously with traditional static load. This study carried out using the finite element program PLAXIS 3D. The linear elastic model for retaining walls and the Mohr-Coulomb model for soil layers were used in this numerical analysis. The study included three layers of soils under the wall with dry condition. The high of the wall was 4m and the dimensions of machine foundation were 3x3m. It can be concluded that the vertical settlement, horizontal displacement and velocity increased when the duration of the machine load increases. Usually, the horizontal displacement increases to highest value and reached to 10 times the original static value when the machine was closed to the wall with 0.5m and 75Hz. This can be taken into account in the design for such geotechnical system in the design stages.

Authors: Ahmed Balqees , O. Abbas Hassan
Published: June 2024

Concrete dams are the strongest dams, designed for flood control, electricity generation, and water management. They can become unstable due to ground shaking and earthquake impacts, resulting in stability loss due to embankment and foundation materials or severe deformations like slumping, settlement, cracking, and slope collapse. Where consider an earthquake one of the factors that pose a major threat to dams, especially if the earthquake is strong and if the soil under the dam is sandy soil, so that geotechnical designers should consider more than any other disaster when developing construction in seismically active areas. Therefore, a laboratory study was conducted on a model of concrete dam with dimensions (width =15 cm, high = 20 cm, and thick = 5cm) on fine sand soil. In order to study the stability of the concrete dam subjected to earthquake vibration, the model of the dam was subjected to different types of earthquakes (Halabja and El Centro). The main goal of the study is understanding the behavior and performance of concrete dam subjected to seismic load. It can be concluded that the stability of the concrete dam subjected to earthquake depends on the intensity of the earthquake. Thickness and width of the dam.   According to the results, the El-Centro earthquake effect on concrete dams is 60% greater than the Halabja earthquake.

Hybrid composite materials combining polymers and reinforcements are gaining interest for enhanced engineering properties. The main goal of this study was to create the best hybrid composite using carbon fibers, zinc oxide micro- and nanoparticles, epoxy, phenol-formaldehyde resin, and more. Samples with varying ratios of epoxy resin (50–100%) and phenol-formaldehyde resin (0–50%) were fabricated. Mechanical and water absorption testing evaluated the effects of the zinc oxide particles and carbon fibers on tensile strength, elasticity, and liquid resistance. Results showed improved tensile strength and minimized water absorption at 10% phenol resin content. Further, zinc oxide nanoparticles offered better reinforcement than microparticles, attributed to higher surface area-to-volume ratios. However, carbon fiber addition increased water absorption despite improving tensile properties. In the end, the best composite was made up of carbon fibers, zinc oxide nanoparticles, 90% epoxy resin, and 10% phenol-formaldehyde resin. This affordable hybrid composite has potential applications in sewage system piping. Further work should focus on improved mixing methods to leverage synergies between the composite constituents. The study provides valuable insights into tuning hybrid composites with nanoparticles and fibers for advanced functionality.

Published: June 2024

The conventional methods follow in designing piles adopt the assumption of saturated condition of soil depending on soil parameters at saturated condition while at most cases the whole piles or part of them lays in unsaturated soil zone, thus the estimated pile capacity will be far of the real. This issue made the need to study the pile capacity at unsaturated condition and compare it with saturated condition. This study is performed to investigate the behavior of single pile inserted in clay soil at different degrees of saturation. The test was performed under axial compression loads by using different degrees of saturation (100,80,60,40%). A pile of 14x14 mm cross section with different slenderness ratios (L/D) (24,30,36) employed in the study. The impact of saturation degree, matric suction and slenderness ratio on pile load capacity is examined. The results illustrate that pile capacity influenced considerably by the saturation degree, matric suction, and slenderness ratio. The results showed that when saturation degree reduced from 100% to (80,60,40%), bearing capacity of pile increased for all L/D used. An example ultimate capacity of pile with L/D (24) increased (380, 512, 63%)  by de-creasing degree of saturation from 100 % to(80 ,60 ,40%) respectively, this means the pile capacity increased about four times by decreasing Sr. from 100 % to 80 % , five times by decrease Sr. from 100% to 60 %  and little increase (63 %) in pile capacity by decreasing Sr. to 40 %.A close results had been observed at L/D 30 and 36. The effect of increasing slenderness ratio had been studied at different saturation degrees, an ex-ample by increasing L/D from 24 to 30 pile capacity increased (11.45, 10.2, 25, 32.5%) at Sr.(100 ,80 ,60 ,40%)  respectively.

Adolescents' involvement as perpetrators of criminality in Indonesia has gone beyond the patterns of deviant behavior and actions categorized as juvenile delinquency. Adolescents' involvement as perpetrators of criminality has not been given much scientific attention in previous studies. This study focuses on the question, "How is the involvement of adolescents as perpetrators of criminality that occurs in Indonesia?" This study uses a descriptive qualitative approach to exploring the forms, characteristics, and factors that influence a teenager to become a perpetrator of criminality disseminated through online media coverage. The collection and reading of online news focused on news titles containing criminality cases involving teenagers by using the search keyword "Involvement of teenagers as perpetrators of criminality in Indonesia" on the Google search engine. The findings in this study show that the involvement of teenagers as perpetrators of criminality has gone beyond the deviant behavior patterns of juvenile delinquency. The context can be reflected through the forms and characteristics of the acts committed by teenagers, ranging from maltreatment, drug abuse, to murder. This study also recommends the importance of looking at the welfare of adolescents as perpetrators of criminality and the law enforcement process to obtain a comprehensive and more empirical understanding.

Authors: Wargadinata Ella Lesmanawaty
Published: June 2024

Irrational beliefs such as myths, legends, and taboos play a role in protected area conservation or biodiversity; however, those remain unanswered in their conceptualization and practices. This research aims to reveal how a myth as an ancient institution evolves into a modern institution accepted by today's generation. It uses institutional transformation as an essential guide to reveal the linear transformation from old legend as a traditional institution into a modern multi-actor collaboration—data collection through observation, interviews with purposive informants, and support by secondary data. The result shows that the current Lake conservation covers long run long-institutional evolution: from the legend of the Zamzam water as the starting point, the legalization of the site as a natural conservation area, the strong kinship bond among local peoples, the metamorphosis of myth into public cultural events; to modern Collaborative action on religious tourism management of who, what, and when benefit and responsibility from different actors are shared. The institutional transformation has become a focal point over modernization that is intertwined and plays a significant role in the Lengkong Lake conservation.

For most of the East Nusa Tenggara (NTT) people, waving traditions and ikat woven products are not just common local product or cultural manifestations. Each motif in ikat woven product has its own symbolic representation. This is a qualitative descriptive study carried out using an ethnographic research model. The data was collected by observing a number of ikat artisans and their cloth products, providing deep interview to related parties in the manufacturing process including meanings behind the decorative motifs in the ikat woven clothes. This study relies on of data notes linked to the research object as well as images of woven ikat cloth products in NTT.  The result showed that the woven cloth products locally manufactured in NTT, with varied ornamentation and motifs are subject to local knowledge values and symbolic meanings that have a spiritual and mystical aspects. Many motifs on the cloth developed identify each regional area in NTT. Ikat cloth motifs are symbols of communication tools; i.e., Ende-Lio motifs associated with traditional rituals are represented by cloth motifs are the symbols for regulations that must be implemented by the people. For people of North Mollo, NTT, ikat woven product with identical motifs have widely been used for blankets and sarongs named as Pauf designed exclusively for males to wear. In Pauf, there are two interpretations of the rhombus-shaped symbols on Lulat Pohok and Lulat Kollo, which symbolically are the expression or reflection for social interaction between society and the ruler or king.

Objetivo: Analisar e descrever os aspectos epidemiológicos dos acidentes por animais peçonhentos ocorridos no Estado do Pará. Métodos: Estudo observacional, transversal e descritivo de dados dos casos notificados do DATASUS (subseções do Sistema de Informações de Agravos e Notificações - SINAN). Resultados: No Pará, de 2017 a 2022, foram notificados 52.004 acidentes por animais peçonhentos, com um aumento de 38,1% no número de casos nesse período. A faixa etária de maior incidência (37,2% de notificações) foi a de 20 a 39 anos e o sexo masculino (74,5% dos casos) foi o mais acometido, sendo 79,4% em pessoas da raça/cor parda. Quanto à escolaridade, a prevalência foi dos indivíduos semi-alfabetizados, com até a 4ª série incompleta do ensino fundamental (18,1% dos casos). As serpentes causaram maior número de acidentes (61,0%), destacando-se o gênero Bothrops (56,2%). Os acidentes leves, com desfecho clínico de cura, foram de 62,6% e 85,6%, respectivamente. Conclusão: Infere-se que o aumento dos casos ao longo dos anos correlaciona-se com a crescente urbanização e consequente ocupação do habitat dos animais. Adultos jovens do sexo masculino, pardos e com baixa escolaridade foram os mais acometidos e os acidentes ofídicos (botrópicos) foram mais prevalentes.
