Electronic monitoring (EM) systems are tools that can generate fisheries survey data when at-sea
challenges such as on-deck logistics, workload capacity, or deployment interruptions prevent staff
from fulfilling their duties. We sought to validate EM’s specific utility in collecting fish lengths at
a comparable resolution to those collected at sea during a fishery-independent survey, the Gulf of
Maine Bottom Longline Survey. We also examined whether measurement accuracy was influenced
by tail morphology and length type (fork, total, and stretched total) by selecting individuals from six
anatomically variable species. Individuals were measured twice: Survey-based length measurements,
LS, were recorded using an electronic measuring board and EM-based length measurements,LE, were
visually estimated using a color-coded EM measuring strip during video review. Paired Wilcoxon
signed rank tests determined significant differences between the LS and LE distributions for all species
overall, and for individual species Atlantic cod, cusk, haddock, and spiny dogfish but not thorny
skate or white hake. Kolmogorov-Smirnov tests detected no difference between the distributions of
LS and LE,
overall and for each species. Examination of the differences between LS and LE for every
individual, LD, indicated that the EM-based method slightly over-estimated lengths (μ = 0.89 mm).
Linear regression indicated that the effect of extreme small or great lengths on absolute LD was present
only for Atlantic cod where LD increased as fish length decreased. Pairwise comparisons of LD among
fish length types indicated that fork and stretched total length measurements were overestimated by
the EM-based method (μ = 2.39 mm, 3.09 mm, respectively) and this was significantly more than
total length (μ = 0.04 mm). We demonstrated that collection of fish lengths using video review could
be an adequate substitution for collecting lengths by hand, though it is at the discretion of the end
users to determine whether these length differences exceed the acceptable range. These results have
particular applications to small scale survey operations, research, and the fishery-dependent sector

Interlocking concrete blocks have gained significant attention in sustainable construction due to their inherent advantages, including reduced mortar requirements and ease of assembly. This study investigates the influence of incorporating Guinea-Corn Husk Ash (GCHA) and saw-dust ash (SDA), on the mechanical and microstructural properties of interlocking concrete blocks. Concrete mix proportions were established with a mix ratio of 1:2:4 (cement-GCH and SDA), and a water-to-cement (w/c) ratio of 0.6. The aggregates, GCHA, SDA, and granite, underwent sieve analysis to determine particle size distribution in accordance with BS 812-103.1standards. Manual concrete mixing was carried out following the procedures outlined, and the resulting concrete mixes were poured into plastic molds and subsequently placed in a curing room at a temperature of 27 ± 5 oC. The concrete samples treated with cement and subjected to Scanning Electron Microscope (SEM) analysis at different magnification rates (x8000, x9000) and resolutions (10 µm, 50 µm, 100 µm) for a curing period of 56 days, were then analyzed. For the elemental composition of the cement samples, the control sample indicates that calcium is the major element in ordinary Portland cement, constituting 69.10 wt%. However, for samples with blended cement of guinea-corn stalk and sawdust ash, calcium remains the major element but with varying percentages of 60.30, 40.00, 50.00, 56.15, 50.00 wt%, respectively. The results suggest that the addition of GCHA and SDA with cement leads to a decrease in calcium composition, potentially impacting construction.

Authors: Stanley A. Omenai
Published: August 2024

This paper review presents the results of a Novel method for non-invasive blood pressure measurement from the finger using an optical system based on dynamic light scattering developed by Elfi-Tech's innovative technology group [1]. A small-scaled, optical, mobile device that measures BP at the finger using dynamic light scattering was developed. The device is positioned at the base of the index finger and contains a ring with an inflatable cuff with two miniaturized dynamic light scattering (mDLS) sensors situated away from, but close to the cuff. The cuff is inflated to above systolic pressure, and changes in blood flow (hemodynamics) are measured during deflation of the cuff. Blood Pressure measurement is carried out using specially designed algorithms based on hemodynamic indexes and waveform analysis which capture systolic and diastolic points in real-time.

Authors: Amália Cinthia Meneses do Rêgo  , Irami Araújo-Filho
Published: August 2024

Severe acute pancreatitis (SAP) presents a complex clinical scenario that demands prompt and accurate decision-making regarding the appropriate course of treatment. The management of SAP involves a delicate balance between surgical intervention and conservative therapy, aiming to optimize patient outcomes while minimizing morbidity and mortality. Traditional methods of assessing disease severity, such as the Balthazar scale, Ranson criteria, Glasgow-Imrie score, and APACHE II score, provide valuable clinical insight but may lack the precision necessary for individualized patient care. In recent years, integrating artificial intelligence (AI) technologies into healthcare has shown promise in augmenting clinical decision-making processes. By leveraging machine learning algorithms and predictive analytics, AI has the potential to enhance the accuracy and efficiency of severity assessment in SAP. This article explores the role of AI in conjunction with existing severity scales in aiding surgeons' decision-making regarding the timing and modality of intervention in patients with SAP. Through a comprehensive review of current literature and case studies, we will examine the advantages and limitations of AI-based approaches and propose strategies for integrating these technologies into clinical practice. By harnessing the power of AI, surgeons can potentially optimize patient outcomes, improve resource utilization, and reduce the burden of SAP on healthcare systems worldwide.

Published: August 2024

There are several psychological factors that can affect the development of students' speaking skills in English. This study was conducted with the aim of finding out what psychological factors affect the development of students' speaking skills in English when learning speaking in class. This research uses descriptive qualitative method, where data collection was carried out through observation and interview with some private junior high school students in grade 7 with ICO (International Class Orientation) class program. The results of this study show that there are four factors that can hinder students in developing and also mastering speaking skills, namely anxiety or shyness, lack of confidence, lack of motivation, and fear of making mistakes. These four psychological factors have a negative impact on students during the speaking learning process. Therefore, the findings of this study imply that parents and teachers should help students understand that making mistakes is a necessary part of learning and that they can take advantage of these opportunities to grow as communicators. In order to give students the chance to practice speaking English without worrying about making mistakes, the teacher must also foster a supportive environment in the classroom.

FSUE “RADON” was developed a technology and pilot plant for conditioning spent ion exchange resins (IER) by dehydration and incorporation into a polymer binder. According to the regulatory requirements of the resulting polymer compound, studies of its radiation resistance have been carried out using developed and certified methods. Mechanical strength was adopted as an indicator characterizing the structure of the polymer compound. It was found that when irradiated at dose 104 Gy, the strength of the polymer compound increases. This can be explained by the phenomenon of radiation crosslinking, which leads to the formation of additional chemical bonds and hardening of the compound material. The volume of polymer compound samples decreases during irradiation at doses 104 – 106 Gy, which guarantees the preservation of the integrity of containers with the compound during their storage/burial. The values of the leaching rate of radionuclides are also decreasing, while being within the requirements of NP-019-15. The results of a study of the radiation resistance of a polymer compound with spent IER included indicate that it retains its structure and water resistance as a result of irradiation, which confirms the compliance of this material with the requirements of NP-019-15.

Nanoparticles of transition metal chalcogenides are a promising material for creating fairly cheap and efficient electro- and photocatalysts for producing hydrogen by water splitting. The method of pulsed laser ablation in liquids makes it possible to obtain nanoparticles whose characteristics depend on the chemical nature of the ablated targets and the composition of the liquid. In this work, nanoparticles obtained by ablation of a WSe2 target under nanosecond laser pulses in water and isopropyl alcohol were studied. The size of the nanoparticles varied in the range from ~ 20 to 200 nm. During pulsed laser ablation in water, the formation of tungsten oxide nanoparticles dominated. Nanoparticles obtained by laser ablation in alcohol contained nanophases with different valences of tungsten W6+ (WO3), W5+ (W−Se−O), W4+ (WSe2) and W0. No obvious signs of carburization of these nanoparticles were found. In both cases, elemental selenium that did not react with tungsten during laser ablation was released in the form of crystalline and/or amorphous nanophase. The possibility of using the created nanoparticles as photocatalysts for the hydrogen evolution reaction was analyzed.

Geographically Weighted Negative Binomial Regression (GWNBR) model is the development of Negative Binomial Regression (NBR) model applied to spatial data. The parameter estimation of GWNBR model is performed at each observation location using spatial weighting. The purpose of this study is to determine the GWNBR model of the number of pulmonary tuberculosis cases in Indonesia in 2021 and determine the factors that influence pulmonary tuberculosis cases in Indonesia in 2021. The research data are secondary data obtained from the Indonesian Ministry of Health and Indonesian Central Agency on Statistics. Parameter estimation method is Maximum Likelihood Estimation (MLE). Spatial weighting is calculated by using the Adaptive bi-square weighting function and the optimum bandwidth is determined by using the Cross-Validation (CV). The research results showed that the exact Maximum Likelihood (ML) estimator could not be obtained analytically and the approximation of ML estimator was obtained by using the Newton-Raphson iterative method. Based on the results of the parameter testing of GWNBR model, it was concluded that the factors affecting the number of tuberculosis cases were local and varied in 34 provinces. The factor affecting locally are population density, the percentage of districts/cities implementing GERMAS, and number of hospitals.

Published: August 2024

Este estudo teve como objetivo analisar a relação entre encarceramento e tráfico de drogas, considerando o estado de Minas Gerais, um dos mais importantes do país, no período 2013-2017, por meio da estimação de um modelo econométrico com dados em painel dinâmico. Os resultados apontaram que o encarceramento atua como promotor do crime de tráfico de drogas, já que os aftereffetcs, bem como os efeitos de perturbação social que o aprisionamento gera, superam os efeitos deterrence e incapacitation. Nesse sentido, destaca-se a superlotação de presídios e as condições precárias verificadas no sistema prisional brasileiro como catalisadoras dos aftereffects.

This article presents a novel approach to a decision support system for handling uncertainty and impreciseness in a large amount of human opinion. Sometimes, the aggregation of real-life applications is quite complex due to incomplete and redundant information about different preferences or alternatives. To handle such type of situations, a spherical fuzzy environment is a more effective and feasible framework with four components membership, abstinence, non-membership and refusal degree. We also formulate some flexible operations of Sugeno-Weber aggregation operators. Motivated by the theory of Sugeno-Weber t-norms, we constructed a family of mathematical methodologies, including Sugeno-Weber weighted average and weighted geometric operators in the light of spherical fuzzy information. An appropriate decision-making technique of the multi-attribute decision making (MADM) problem is also demonstrated to resolve complicated real-life applications. A numerical example is used to verify the compatibility and effectiveness of discussed mathematical approaches.

Growth variability is a key contributor to the dynamic productivity of populations. Thus, better understanding and accounting for variation in growth can improve both tactical and strategic management. Using ocean shrimp (Pandalus jordani) from the U.S. West Coast as a case study, we demonstrate interactions between growth and optimal fishery opening dates. While the fishery opens on April 1, industry often delays fishing to minimize catches of small shrimp. Understanding drivers of size-at-recruitment can help managers optimize opening dates and shrimpers plan their participation in this and other fisheries. Using three decades of fishery-dependent sampling, we built a spatially-, temporally-, and environmentally-explicit Bayesian state-space model for shrimp size-at-age. Model outputs were then used to parameterize a revenue-per-recruit model and explore how variability in size-at-recruitment impacted optimal opening dates. Shrimp recruited at smaller sizes farther north. Delaying opening would likely benefit shrimpers in areas and years with smaller shrimp and higher fishing mortality. Broadly, choosing when to open the fishery is a complex decision requiring understanding of growth, but also recruitment, economic incentives, and life history.
Taphonomic Controls on a Multi-Element Skeletal Fossil Record

Animals with multi-element skeletons, including the vertebrates, echinoderms, and arthropods, are some of the most biodiverse and ecologically important animal groups. Understanding the relative impact of the myriad geological and biological factors which impact on the quality of multi-element skeletal fossils is thus crucial for disentangling perceived changes in biodiversity through time and shedding light on gaps in the fossil record. We have characterised the specimen-level taphonomic history of virtually the entire Palaeozoic fossil record of echinoids, the class of echinoderms which includes the living sea urchins. We find that the majority of this fossil record consists of disarticulated skeletal elements and as preservational quality increases, so does the proportion of specimens which can be identified with higher taxonomic precision. We then assessed the relative impacts of multiple geological and biological factors on our specimen quality, identifying that fine-grained host matrix, as well as siliciclastic lithology are the biggest factors in determining quality of fossil echinoid preservation, while aspects intrinsic to specific taxonomic groups also play a role. Differential sampling of the fossil record seems to play little role in influencing the distribution of taphonomic grades, and fluctuations in the North American record of Siliciclastic rocks are positively correlated with fluctuations in taphonomic grades. Our results highlight that the factors controlling the animal macrofossil record are varied, and that the interplay between these variables, taphonomic grade, and taxonomic precision impacts on our ability to use the fossil record to understand macroevolution.
Functional Communication Training
Authors: Mason Lee , Andrews Alonzo
Published: August 2024

Chapter 10 focused on the distinct functional properties of verbal behavior, such as mand control (i.e., requesting). Mand training is a technique for strengthening a child’s ability to request access to specific reinforcers, like toys, snacks, activities, and interactions with other people. Research has shown that verbal behavior may need to be explicitly reinforced as a request for it to be useful as such. Mand training may lead to an increase in spontaneous language, an increase in social initiations, and a reduction of problem behavior. However, sometimes challenging behavior interferes with skill acquisition. When challenging behavior occurs at high rates or presents a potential for harm, mand training may be combined with extinction through a chaining procedure known as functional communication training.

Marriage is a legal act that is recognized by the Indonesian state. However, divorce in a marriage is expected today and is no exception in Indonesia. Divorce is determined in Act Number 1 of 1974 concerning Marriage. This research wants to contribute to family law in the divorce system for the Hindu community in Bali, seeing that there is no position against legal customary rules and Hinduism, which in Article 39 determines the validity of a divorce. This research focuses on library research with a descriptive-analytical way and statute approach. The result of this study is that in Balinese legal customary divorce process, there should be strong reasons, as contained in the Vedic Scriptures, such as the Garuda Purana, to take divorce steps. The divorce system that indigenous people in Bali can carry out is the palas perabian system and continues with the mapegat sot sacred ceremony. The legal consequences of divorce in the Hindu community in Bali do not affect the status and position of the child because the Hindu community in Bali adheres to a patrilineal family system (purusa). The legal consequences related join property (gunakaya), whether inherited property from the husband or inherited property of the wife from the parental gift (tetatadan), will return to each party in the event of a divorce.
Harmonisasi Jabatan Notaris Dan Informasi dan Transaksi Elektronik Dalam
Cyber Notary
Authors: Kautsar Mensalathiif , Salam Abdul
Published: August 2024

In the industrial revolution 4.0, everything is becoming digital.
Additionally, the COVID-19 pandemic, and the difficulty of meeting face to
face at that time, pushed everything to be done electronically or online.
This is no exception for notaries, who have difficulty adapting to this
all-electronic era. This research is doctrinal research which uses
materials, namely literature and statutory regulations. The research results
show that the Information and Electronic Transactions Law has accommodated
the existence of electronic documents and information, but the Law on Notary
Positions cannot expressly recognize the existence of electronic documents
to be included in authentic deeds. Where other countries have adapted this
cyber notary, Indonesia has not been able to apply it due to obstacles in
these regulations. The exceptions contained in the Information and
Electronic Transactions Law can be removed to provide space for cyber
notaries in Indonesia, but the Notary Position Law must also be adjusted to
provide clear guidelines for the implementation of cyber notaries.

Implementing food security within the provisions of applicable laws and
regulations to accelerate the realization of community welfare through
improving services, empowerment, and community participation, as well as
increasing regional competitiveness by taking into account the principles of
democracy, equality, justice, and the uniqueness of a region. One of them is
the Berau Regency, which still needs a statutory policy that regulates food
security. Even if there is a policy that regulates food security, this
policy is not statutory. It can be considered insufficientinsufficient to
resolve the problem of food security in the Berau Regency. This research
aims to analyze and provide recommendations for regional regulations
regarding food security. The method used is mixed research methods. The
research results show that East Kalimantan has the highest level of food
security. However, there are still quite a lot of problems faced by the
region in implementing food security, namely the conversion of agricultural
land, resulting in environmental damage and global climate change. Legal and
political policy intervention is a form of fulfilling the obligations and
commitment of regional governments as regional government administrators in
the context of implementing food security and fulfilling needs to resolve
various food security problems that are currently occurring, as well as an
effort to prevent other food security problems in the future.
