Authors: Sawant Rohan , Joshi Deepa A. , Menon Radhika
Published: November 2024

Ordinary Portland Cement (OPC) is a major source of CO2 emissions in the environment. Recent micro- and macro-behavioural research has focused on geopolymer concrete (GPC), an innovative alternative to traditional Portland cement concrete. Geopolymers, a cement-based alternative, can serve as a substitute for OPC composites. Geopolymer composites (GC) are more energy-efficient and environmentally friendly than organic polymer composites. The structural features and qualities of reinforced concrete (RC) are very relevant to the building sector. A variety of factors, including the binder material mix, curing conditions, and particle type, influence the strength of geopolymer concrete. Binders like fly ash, slag, metakaolin, and the right alkaline activator change how well the geopolymer matrix sticks together and how strong it is overall. Temperature and humidity, both factors in the curing process, determine the optimal approach for producing the appropriate mechanical properties. The geopolymerization process requires the presence of many components. The mix design has an impact on the concrete's workability, strength, aggregate type, and water-to-binder ratio. To demonstrate that geopolymer concrete is a suitable alternative for conventional concrete. Using SPSS. Identified five key elements influencing the effectiveness of construction Strength of Fiber Reinforced Self-Compacting Geopolymer Precast Concrete using factor analysis. Divide these elements into the following categories: Their classification depends on a number of factors, such as the type and amount of alkali activator used, the mix design and proportions, the geopolymer binder's composition, the presence of adjuvants or additives, and the curing conditions.

Published: November 2024

The expansion of the infrastructure industry has led to the production and use tons of cement. A significant amount of CO2 has been released throughout the cement-making process. A growing number of people are considering agriculture waste as a feasible substitute for conventional cementitious materials due to its high silica concentration and renewable nature. The waste-free renewable energy source known as sugarcane bagasse ash (SCBA) is produced from the fibres of sugarcane. In this experimental study SCBA as a partial replacement of cement has been utilized to test strength and durability of the concrete mix. In this experimental work sugarcane bagasse ash is partially replaced as 2.5%, 5.0%, 7.5%, 10.0%, 12.5%. 15.0% and 20.0% with cement in concrete mix. The experimental results concluded that compressive strength increased when 10% SCBA was substituted, and split tensile strength maximum strength increased somewhat after that. The results of the investigation support the notion that the concrete used in construction has excellent durability when partially replaced with (SCBA). Additionally, the flexural behavior performed exceptionally well when replaced with 10% bagasse ash. Owing to its microparticle size and crystallographic character, bagasse ash exhibits increased performance when used as a supplementary material. The study concluded overall performance is achieved by replacing 10% of the SCBA in treated concrete.

Authors: Thakur Aishwarya , Reddy V. Phaninder , Chandrashekar Rakesh , Sura Sreekanth , Kumar Manish , Reddy V Mallikarjuna
Published: November 2024

Sustainability has been expected in all fields in recent years, and civil engineering is no exception. Therefore, it is crucial to handle sustainability carefully. Subsequently, research on self-healing materials in concrete has been increasingly focused on this concern. When a crack in the concrete occurs, self-healing materials can repair it. A portion of the damage induced by mechanical loads (pores, microcracks, etc.) can be recovered by these materials, which belong to the superfamily of “smart materials.” The crystalline additive in the current investigation induces artificial healing in concrete. Various methods are used to increase the ability of the concrete to mend itself using various ingredients; in this instance, the user may want to consider environmental exposures and think about employing crystalline additives and nano clay. Cement replacement percentages with nano clay were 2%, 4%, and 6% with adding 1% crystalline admixture. After being subjected to a range of climatic conditions for 28 days, the specimens were pre-cracked to a size of 0.10–0.40 mm. All mixes exhibit a high degree of closure ability and strength-regaining capacity, according to the outcome, given all exposure circumstances. The maximal potential of concrete to seal fractures and regain strength should be demonstrated by using 1% crystalline admixture (CA) and 4% nano clay in all exposure scenarios.

Authors: Shameem Sabahat , Sharma Vishal
Published: November 2024

The construction industry has advanced to a great extent by using natural fibres and mineral admixtures in concrete taking sustainability into account. The addition of glass fibre at less proportion has shown some interesting values in terms of tensile behavior. Admixtures have mostly been used in concrete to support the development of work in the construction industry. Certain admixtures are required to get the intended effects out of the concrete. The paper revolves around the examination of the mechanical behavior of glass fibre-reinforced concrete (GFRC) with cement partially replaced by silica fume such as compression test and split tensile strength. Silica fume as an admixture is added to glass fibre-reinforced concrete in this paper in varying quantities to partially replace cement. Glass fibre 1% and silica fume at varied percentages such as 15, 20, and 25% have been used. The compressive strength increased by 13% and tensile strength by 40% in comparison with conventional concrete.
A Review on Sustainable Utilisation of Zinc Mine Tailing in Concrete Production
Authors: Maqbool Rather Haris , Hasan Murtaza
Published: November 2024

India is among the largest mineral and metal producers globally, including coal, iron ore, bauxite, and zinc. These resources are extracted and processed to create tonnes of mine tailings which are usually disposed into waste or tailings dams. It is estimated that around 80 million tons of mine tailings every year in the country. Zinc tailing is a byproduct from zinc extraction during production that contains several hazardous components like iron, silica, zinc, lead, aluminium oxides cadmium amongst others. These impurities often have adverse effects on people’s health as well as the environment surrounding dumping sites. Nonetheless, in recent years, the utilisation of waste materials in concrete production has become popular due to its ability to enhance the sustainability of the construction industry. The purpose of this review paper is to look into the possibility of replacing some of the fine aggregates and cement in concrete and mortar with zinc tailings. The use of zinc tailing as a substitute for cement in concrete could be an effective way to reuse industrial waste and decrease the environmental impacts associated with cement production. Zinc tailings have diverse physical and chemical properties making them suitable for various construction purposes. The studies have shown that, ideally, the zinc tailing should be 5-20% of the weight of cementitious ingredients. It has been proven that this helps to enhance workability, compressive strength and durability in concretes. Thorough investigations need to be carried out to establish the long term durability and environmental sustainability of these materials although they have been found to reduce pollution and promote sustainable development.

Published: November 2024

Providing natural light with daylighting in the interior space of a residential building is essential to sustainable architecture. This research reviews how different daylighting strategies affect energy use in Residential buildings in various climate zones in India. Due to drastic changes in climate variations across India, this research on daylighting strategy is unique. In each region, tailored techniques are crucial for energy preservation.

In this research, papers published in Scopus, web of Science, and Google Scholar-indexed journals from 2008 to 2024 have been included. Starting from traditional daylighting techniques, which are part of India's architectural heritage, such as courtyards, windows, and reflective surfaces till advances to more contemporary techniques like light shelves, skylights, and sophisticated glazing materials that are climate- specific and maximize daylight penetration while decreasing heat gain discussed in this research.

In India's hot-dry, warm-humid, composite, temperate, and cold climates, the effectiveness of techniques varies. This study also includes shading devices, window-to-wall ratios, and building orientation. This study's findings demonstrate that daylighting strategies have universal benefits, but some must be tailored to the climate-specific context to achieve maximum energy efficiency.

This extensive analysis will be helpful for the use of energy-efficient daylighting techniques that are sensitive to the region's unique climatic challenges and cultural landscape by serving as a resource for Indian architects, designers, and policymakers.

Published: November 2024

In current era, construction activities are essential for modern civilization. Steel, concrete, wood, and glass are key materials for construction. Among all, concrete is further gaining rapid recognition due to its inherent properties. However, making of concrete involves use of natural resources, which is a growing concern over the depletion of natural resources in construction. Owing to that need of sustainable alternatives such as RCA are gaining attention very rapidly. Current study examines the strength and durability aspects of HSC using unprocessed and processed RCA. The mechanical properties of concrete were evaluated in a three-stage analysis, comparing mixes made with natural aggregates, unprocessed RCA, and processed RCA. The processing of RCA involved mechanical grinding, optimized through Abrasion, with replacement levels of 25% and 50%.The compressive strength results indicated that a 25% replacement of natural aggregates with processed RCA achieved the target strength, outperforming concrete with unprocessed RCA but remaining lower than natural aggregate mixes. Tests, including Rapid Chloride Penetration Test, Ultrasonic Pulse Velocity, and Sorptivity, were conducted to assess the long-term performance. Processed RCA at 25% replacement exhibited improved durability, with lower chloride ion permeability, higher UPV values indicating better homogeneity, and reduced sorptivity, reflecting enhanced resistance to moisture ingress. These findings highlight that processed RCA offers a viable solution for sustainable concrete production, with strength and durability characteristics comparable to traditional materials at lower replacement levels.

Published: November 2024

Experimental and statistical analysis of the corrosion inhibition properties of grapeseed oil (GSO) on high carbon steel (HCS) and ferrovanadium (FVA) in 0.25 M H2SO4 solution was done. Results from gravimetric analysis show GSO performed more effectively on HCS with average inhibition efficiency above 90% at all concentrations compared to FVA where the values where generally around 70% at 360 h of exposure. Inhibition efficiency results did not vary significantly with GSO concentration compared to exposure time over 360 h. Secondly, inhibition efficiency values increased with respect to exposure time from initiation. ANOVA statistical method at 95% confidence level and significance level of 0.05 shows the sources of data variation (exposure time and inhibitor concentration) has minimal influence on the inhibition performance output of GSO. This indicate they are statistically indeterminate. The inhibition data is due to factors relating to presence of phytochemical properties, organo-metallic interaction, adsorption mode and influence of corrosive species. Data from standard deviation shows GSO inhibition efficiency data varies minimally from mean inhibition values from HCS which contrast the values obtained for FVA which were significantly high. The results show greater thermodynamic stability of GSO inhibition on HCS compared to FVA. 82% of GSO inhibition data from its action on HCS are above 70% inhibition compared to 22% for FVA.

The advances in technological developments in NFPCs are driven by the demands of a nation toward sustainability and ecologically friendly materials. Banana, eucalyptus, and kenaf-based material from natural fibers may confer several environmental benefits, including being biodegradable, having a reduced greenhouse gas, and carbon footprint. Despite these benefits, NFPCs exhibit drawbacks in mechanical performance. Poor interfacial adhesion, moisture absorption, and limited fire resistance are some examples of reasons hindering their broader use. Enhancement of fiber-matrix adhesion has been seen as a way of achieving enhanced mechanical properties of NFPCs, and the alkaline treatment using NaOH has come to be favored. Further, since such companies started using NFPCs as they are light in weight and green, such a review indicates a global trend towards sustainability, especially in the aerospace and automotive industries. Further innovation into these NFPCs will be a filling process with nano-clay and other nanoparticles for enhanced thermal and mechanical properties since such a material has immense potential of outperforming their rivals, which are mainly petroleum-based materials. In addition, review also discuss the increasing usage of biodegradable polymers such as polylactic acid, PLA reinforced with natural fibers to improve durability and mechanical performance, opening up new possibilities for various applications such as in construction and packaging and medicine and even in 3D printing. Advancements in NFPC technology are aptly highlighted as these materials can meet diverse needs evolving in several industries to ensure a greener tomorrow.

Published: November 2024

Water is the basis for human survival and socioeconomic development, but rapid population growth, rise in industries, and agriculture pose a threat to the quality and availability of freshwater resources. The greater part of international water treatment techniques seeks to ensure that the drinking water is safe through coagulation, flocculation, sedimentation, filtration, disinfection, and pH correction processes. While their reliability has been amassed over the years, these techniques have huge limitations in terms of scalability, efficiency, and ability to adjust to new, emerging contaminant risks. Some of the state-of-the-art technologies in terms of water treatment, discussed in this paper, include nanotechnology, membrane filtration, advanced oxidation processes, and biological treatments. Nanotechnology utilizes Nano adsorbents and catalytic materials to remove contaminants efficiently with antibacterial effects. On the other hand, advanced membrane filtration technology improves water flux and antifouling properties while raising contaminant rejection. AOPs use hydroxyl radicals to degrade organic and inorganic pollutants effectively. Biological treatments utilize microorganisms for biodegradation and hence are sustainable and effective. This paper therefore, discusses the outcomes of such innovative methods in terms of efficiency, application, and future potential to underline recent developments and future prospects of water treatment technologies. Application of these innovative approaches into water treatment frameworks will enhance water purification by surmounting the drawbacks of the conventional techniques that ensure reliable supplies of clean water globally. The paper has focused on in-depth analysis of the processes being developed in improving water quality and access with respect to global health and socio-economic development.

Published: November 2024

Glue-free wheat straw-based fiberboard has the advantages of excellent performance, such as no formaldehyde release, being renewable, and being degradable, which presents a novel approach to enhance the utilization value of straw and protect the environment.. In this study, wheat straw was first pre-treated to remove impurities such as wax and silica contained in wheat straw by a 2% sodium hydroxide solution, and further modified by carboxymethylation and acylation to obtain wheat straw fiberboard raw materials with different functional properties. Then, H2O2 was used as the initiator, and the wheat straw fiberboard raw materials were hot-pressed at 100 °C and 140 kg/cm2 to prepare glue-free wheat strawbased fiberboard with the bending strength of 95.43 MPa, the impact toughness of 2.68 kJ/m2, the tensile strength of 9.2 MPa, the elastic modulus of 1773.03 MPa, and the hardness of 81D. The performances of the prepared glue-free wheat straw-based fiberboard with zero formaldehyde have surpassed that of the general glue-free board and have the potential to replace wood board.
Chromodynamique quantique sur réseau
Authors: Lellouch Laurent
Published: November 2024

La chromodynamique quantique (QCD) est la théorie qui décrit l’interaction forte, responsable entre autres de la cohésion des noyaux atomiques. Cette interaction devient hautement non linéaire lorsque les particules qui interagissent ont des impulsions relatives inférieures à environ 1 GeV/c. Dans ce régime, ses effets peuvent être calculés dans le formalisme de la QCD sur réseau, à l’aide de simulations massivement parallèles sur des super-ordinateurs.

Après une introduction historique à l’interaction forte, cet article explique ce qu’est la QCD et comment sont faits les calculs sur réseau. Il décrit ensuite le calcul d’une contribution QCD au moment magnétique du muon et comment les résultats qui en découlent participent à la recherche actuelle de nouvelles particules et interactions fondamentales.

Published: November 2024

Angesichts der stetig voranschreitenden Verrechtlichung des Gesundheitswesens stehen
Compliance-Fragen auch in Praxen, MVZ und Krankenhäusern zunehmend im Fokus.
Entsprechende Programme stoßen allerdings auf eine selbstbewusste Ärzteschaft, eine
äußerst heterogene Krankenhauslandschaft und ein häufig bereits sehr ausdifferenziertes
Qualitäts- und Risikomanagement. Dass es sich gleichwohl lohnt, den Weg in Richtung
eines effektiven und nachhaltigen Compliance-Managements einzuschlagen, zeigt ein Blick
auf die potenziellen Konsequenzen von Rechtsverstößen: Schon der Anfangsverdacht eines
Korruptionsdelikts oder des Abrechnungsbetrugs kann erhebliche wirtschaftliche Einbußen
und Reputationsschäden zeitigen; im Falle eines Tatnachweises drohen ernsthafte straf-,
berufs- und vertragsarztrechtliche Sanktionen sowie der Honorarregress. Vor diesem
Hintergrund erscheint ein nachhaltiges Engagement in Compliance-Fragen auch als Gebot
unternehmerischer Klugheit.

Published: November 2024

Linear free energy relationships (LFERs) are an important topic in physical-organic chemistry. When one browses the literature, one encounters innumerable instances wherein the series in question conforms to LFER; one also encounters appreciable numbers of examples of non-conformity to LFER. It is extremely rare or maybe we are the first to report simultaneous conformity and non-conformity of Hammett’s relationship (LFER) in the same series, the para-substituted phenyl pentazoles. This rarity and a plausible reason are discussed.
Vietnamese Australian children’s voice on community language schools
Authors: Bui Thi Minh Thu
Published: November 2024

This qualitative study reports Vietnamese Australian children’s perspectives on their learning experiences at
their community language schools. The study draws on interview data with three mothers and their four children (aged 10–12), who
used to attend or are currently attending community language schools in the state of Victoria, Australia. Against the backdrop of
the current limited research on children’s experiences at community language schools, this study is a contribution to the existing
literature in two ways. First, it contributes a children’s voice into research on these so-called marginalised educational sites.
Second, it provides a nuanced exploration of the children’s experiences through the lens of Bourdieu’s (1984) constructs of habitus, capital, and field by discussing how their
perspectives towards their community language schools are shaped by their lived experiences in the fields they participate in. The
findings reveal a mismatch between the children’s habitus, their linguistic capital and the field of community language schools
that they participate in, which explains the children’s unfavorable feedback towards their community language schools.
Aprendizaje horizontal en las relaciones entre militares de las Fuerzas Armadas Españolas e intérpretes en situaciones

Published: November 2024

La comunicación multilingüe y la necesidad de intérpretes y traductores profesionales que sirvan de enlace entre
las distintas partes es una realidad en los conflictos armados internacionales. Este artículo explora las relaciones de
aprendizaje que surgen entre intérpretes y militares en dichas situaciones. El enfoque metodológico se basa en la teoría del
aprendizaje situado de Lave y Wenger (1991) y en la obra de Engeström (1987, 1991, 2001, 2005) sobre comunidades de práctica, con énfasis en las
nociones de aprendizaje horizontal y pedagogías duales, aplicado al caso concreto de las Fuerzas Armadas españolas (FF.AA) que
actúan en operaciones nacionales o internacionales de pacificación o en conflictos armados. Los datos proceden de entrevistas con
militares (españoles) responsables de misiones militares internacionales o que han trabajado con intérpretes. Las conclusiones del
estudio indican el gran potencial que estas misiones tienen para el desarrollo de comunidades de práctica inter e
intraprofesionales entre intérpretes y personal militar como forma para mejorar la calidad y eficacia de la comunicación en
entornos multilingües y multiculturales cada vez más frecuentes en esta sociedad globalizada.
Feminist paratextual (re)framing of online social translation
Authors: Cheng Xiaoyi
Published: November 2024

This study focuses on a range of paratexts around an influential social media account in China named @subtitle girl, who dedicates herself to online feminist content production in the form of (editing) and subtitling feminist clips from English to Chinese. The study aims to identify how the feminist subtitled clips are paratextually (re)framed in the context of digital feminism. The study adopts a suitable theoretical conceptualization of paratextuality and views @subtitle girl’s translational activities under the online social translation/subtitling rubric. Different paratexts around @subtitle girl’s subtitling are examined on the macro and micro level. It is found that, on the macro level, the factual paratextual elements avatar, username, and short bio of @subtitle girl, and algorithm-generated statistics about their subtitling facilitate a (post-)feminist (self-)branding and (self-)promotion of their subtitled work. On the micro level, the hashtagged synopsis for each clip and the comments introduce, highlight, reconstruct, and repackage the subtitled feminist content for the Chinese female audience online. The study shows how the feminist (re)framing on two levels of @subtitle girl’s online social translation/subtitling is fulfilled against the backdrop of digital feminist content production: both the (self-)marketing of the producer/subtitler and the interaction between the producer/subtitler and their AV content consumers and among their consumers are valued.
Telling an expressive narrative in a foreign language
Authors: Chen Zhen , Han Zhengrui
Published: November 2024

This study explores the discourse expressivity of Chinese JFL (Japanese as a foreign language) learners’ Japanese
narratives in terms of the variety and use of evaluative strategies, and analyzes how the evaluation system in their first
language (L1) may be evident in their second language (L2) performance. For this reason, using the wordless picture book
Frog, where are you?, we examined the oral narratives produced by adult Japanese native speakers, adult
Chinese native speakers, and Chinese JFL learners. The findings suggest that the absence of “utterance attitudes” in the
Chinese-language narratives is evident in the Japanese-language narratives of the Chinese JFL learners; thus, the evaluation of
JFL stories is somewhat more direct, and the stories are easier to understand than those of adult JNS. However, the evaluations of
the Chinese JFL learners’ narratives also diverged from those of the adult CNS in the direction of the target language’s
norms.
Toward engaged narratology
Authors: Ovaska Anna
Published: November 2024

In recent years, strands of contemporary narrative theory have taken a turn toward a politically, socially, and
environmentally conscious field of study that could be characterized as ‘engaged narratology.’ Creating and disseminating
knowledge about how narratives work, these theories emphasize that narrative forms and strategies are neither universal nor
neutral; they carry out, but can also challenge, systems of inequality and marginalization. They also suggest new combinations of
theory and activism, pedagogical interventions, and community engagement models, offering tools to create social justice. This
article outlines some of these recent developments and reflects on the possibilities of ‘engaged narratology’: how it relates to
engaged research and what kinds of practices have been developed so far. As an example of engaged narratological work, it
discusses the shared close reading of Roxane Gay’s book Hunger: A Memoir of (My) Body (2017) in a multidisciplinary narrative medicine classroom.
Activist interpreting in abortion clinics
Authors: Bartłomiejczyk Magdalena , Pöllabauer Sonja , Straczek-Helios Viktoria
Published: November 2024

We present a case study of a group of activist interpreters Ciocia Wienia, a Vienna-based
informal pro-choice collective. The activists facilitate abortion travel from Poland to Austria, offer onsite support and
interpret in abortion clinics. We analyze original data from a corpus of 13 qualitative in-depth interviews with members and
associates of Ciocia Wienia. Based on a qualitative content analysis, this contribution investigates which
situations and stressors are described as emotionally challenging as well as which coping strategies and techniques of self-care and
mental hygiene are employed to process burdensome emotions. Our results suggest that negative feelings such as sadness,
frustration, anger, stress, and uncertainty make work in such a context emotionally taxing, even though positive emotions are
reported as well. Apart from sharing with the group and supervision, only a few activists seem to have developed a set of distinct
individual self-care and coping strategies.
Wind as a context for Newton’s first and second law and force diagrams
Authors: Watzka Bianca , Omarbakiyeva Yultuz , Hahn Larissa , Klein Pascal , Krumphals Ingrid , Rubitzko Thomas
Published: November 2024

Teachers commonly use examples that omit friction to teach Newton’s first and second law. Beyond the motion of planets, the flow of horizontal high-altitude winds along the isobars presents a real-world motion scenario with negligible friction. This natural phenomenon serves as an applicable context for the exploration of Newton’s first and second axioms and the vector addition of forces. This paper explores wind dynamics as a context that addresses force concepts, a relevant topic in high school physics. Here, we focus on forces affecting air parcels at high altitudes. For comparison, we also explain the wind at ground level (called surface wind), where friction plays an important role. We aim to elucidate the complexities of wind forces, offering a comprehensive understanding of how these forces interplay in real-world scenarios. Furthermore, we provide detailed examples of tasks for high school students to acquire an understanding of wind and aligning forces.
Vetting quark-star models with gravitational waves in the hierarchical Bayesian framework
Authors: Wang Ziming , Gao Yong , Liang Dicong , Zhao Junjie , Shao Lijing
Published: November 2024

The recent discovery of gravitational waves (GWs) has opened a new
avenue for investigating the equation of state (EOS) of dense matter in compact
stars, which is an outstanding problem in astronomy and nuclear physics. In the
future, next-generation (XG) GW detectors will be constructed, deemed to provide
a large number of high-precision observations. We investigate the potential of
constraining the EOS of quark stars (QSs) with high-precision measurements of
mass m and tidal deformability Λ from the XG GW observatories. We
adopt the widely-used bag model for QSs, consisting of four microscopic
parameters: the effective bag constant B
eff, the perturbative quantum
chromodynamics correction parameter a
4, the strange quark mass m

s
, and the
pairing energy gap Δ. With the help of hierarchical Bayesian inference,
for the first time we are able to infer the EOS of QSs combining multiple GW
observations. Using the top 25 loudest GW events in our simulation, we find that,
the constraints on B
eff and
Δ are tightened by several times, while a
4 and m

s
are still poorly
constrained. We also study a simplified 2-dimensional (2-d) EOS model which was
recently proposed in literature. The 2-d model is found to exhibit significant
parameter-estimation biases as more GW events are analyzed, while the predicted
m–Λ relation remains consistent with the full model.
Relativistic Khronon theory in agreement with modified Newtonian dynamics and large-scale cosmology
Authors: Blanchet Luc , Skordis Constantinos
Published: November 2024

We propose an extension of General Relativity (GR) based on a space-time foliation by
three-dimensional space-like hypersurfaces labeled by the Khronon scalar field τ. We show
that this theory (i) leads to modified Newtonian dynamics (MOND) at galactic scales for stationary
systems; (ii) recovers GR plus a cosmological constant in the strong field regime; (iii) is in
agreement with the standard cosmological model and the observed cosmic microwave background
anisotropies at linear cosmological scales, where the theory reduces to a subset of the
generalized dark matter (GDM) model. We compute the second order action on a Minkowski background
and show that it contains the usual tensor modes of GR and a scalar degree of freedom with
dispersion relation ω=0. We find that the deconstrained Hamiltonian is bounded from below
for wavenumbers larger than ∼ 10-31 eV and unbounded for smaller wavenumbers.

This work demonstrates the fundamental possibility of solving quite large-scale problems of seismic data inversion on modern hybrid (quantum-classical) and quantum-inspired annealers using the example of a one-dimensional problem for a horizontally layered model of the medium in the acoustic approximation. The optimization problem for the residual function of observed and model data is decomposed into three problems: the optimization problem for a simpler function of the same dimension, the problem of finding the minimum of a one-dimensional function, and the problem of calculating the terms of a simple recurrent series. Then, the optimization problem for a simpler function is transformed into a quadratic unconstrained binary optimization problem of such a dimension that its solution can be calculated on modern annealers.

Sagor catfish is a demersal species with significant potential due to its large size and economic value. It is primarily found in the waters off Muara Angke coastal waters and the surrounding area of Jakarta Bay. Sagor catfish inhabit muddy seas, coastal areas, and estuaries, often located downstream of rivers up to the high tide mark. This research aims to examine the relationship between length and weight and describe the condition factors of sagor catfish in coastal waters and the surrounding area of Jakarta Bay. Fish sampling was conducted once a month from October 2023 to March 2024. A total of 229 fish were caught using gillnets with mesh sizes of 3 inches. The total length and weight of the sample fish ranged from 167 to 540 mm and 43.2 to 2000 g respectively. The fish length-weight relationships are as follows: W = 5 x 10-6L3.1085 (males) and W = 2 x 10−6 L 3.2456 (females). Fish condition factors ranged from 0.9318-1.2176 (male) and 0.8659-1.2330 (female). These results show that the fish growth pattern is positive allometric and the condition of the fish varied higher value.

This study aims to analyze the test size and growth type of sea urchins (Diadema setosum) on the islands of Kodingareng Lompo and Kodingareng Keke, Makassar City, South Sulawesi Province. This research was conducted for two months, from August to September 2022 on Kodingareng Lompo and Kodingareng Keke Islands, Makassar City, South Sulawesi Province. Kodingareng Lompo represent the seagrass bed ecosystem and Kodingareng Keke represent the coral reef ecosystem. The number of sea urchins caught during the study was 633 individuals in seagrass bed in Kodingareng Lompo and 731 individuals in reef flat in Kodingareng Keke Island. Sample measurement of sea urchins was carried out in situ on the island. Data analysis to determine the size distribution was carried out using a quantitative descriptive approach, including body diameter measurements. The results shows that the test diameter vary from 12,39 - 48,94 mm. The growth pattern of D.setosum sea urchins based on sampling time and station on Kodingareng Keke and Kodingareng Lompo Islands is negative allometric, namely the increase in shell diameter is faster than the increase in weight.

The sea level rise that occurs rapidly on the shores of Lae-Lae Island, South Sulawesi, is reported to be increasing. A study from National Oceanic and Atmospheric Administration estimated that in the next 80 years, the global sea level will be to 8-9 times more than what it is today. National law regarding the management of coastal areas and small islands may exist, but it has not yet been translated into a regional government regulation regarding the current situation. This study aims to address two questions: How does international laws address sea level rise? How does national law regulate mitigation and adaptation on sea level rise that occurred in Lae-Lae Island, South Sulawesi? This study utilizes normative legal analysis by reviewing relevant climate change mitigation and adaptation international and national legal instruments through a statutory approach. This research reveals that regional level regulation is mitigating and adapting to sea level rise as a climate change related disaster in Lae-Lae Island. Therefore, it is recommended that the government prioritize the legislation process using top-down and bottom-up schemes to fix the ineffectiveness that contributes to disaster risk reduction.

Maggot is a good natural food for /ish because it has a high protein content, namely in the range of 30-45%. Azolla pinnata is rich in protein, essential amino acids, vitamins, and minerals and is often used as animal feed. The aim of this study was to analyze variations in fermented Azolla pinnata media for maggot cultivation as a feed preparation for climbing perch (Anabas testudineus Bloch). This research used a Completely Randomized Design (CRD) with four treatments and three replications: Treatment O (Azolla 0%, tofu dregs 80%, and bran 20%), Treatment A (Azolla 10%, tofu dregs 70%, and bran 20%), Treatment B (Azolla 20%, tofu dregs 60%, and bran 20%), and Treatment C (Azolla 30%, tofu dregs 50%, and bran 20%). The results of this study showed that the best biomass was in treatment A, with an average relative weight of 421.33%; the best population growth was in treatment B, with a population of 1,980 individuals; the best relative length was in treatment O, with an average of 255.33%; and weight growth was the best climbing perch in treatment A, with a weight gain of 1.3 g. The use of Azolla pinnata combined with tofu dregs and bran resulted in the highest relative weight growth and maggot population compared to media without using Azolla pinnata.

In 2021, trawling operations in the Arafura Sea were permitted to resume after a moratorium of several years. Therefore, this research aimed to provide up-to-date information to support sustainable tiger prawn management. Data were collected through field surveys and fishing trips aboard a double rig bottom trawler over a one-year fishing cycle (12 months) from February 2023 to January 2024. The monthly tiger prawn catch volume and size composition were recorded and analysed descriptively. The average daily catch was highest in November (803 kg/day) and lowest in May and June (86 kg/day and 64 kg/day, respectively). Tiger prawn weight range was 15-107 g. The most frequently caught size classes were large T-18 (mean 83.3 g/prawn, total volume 13,380 kg) and small T-100 (mean 15 g/prawn, total volume 861 kg). The predominant processed (headless) prawn size classes were L (1,488 kg) and S (614 kg). From December to January, the percentage of small prawns (T-60 to T-100, S and SS classes) increased significantly; therefore, a closed fishing season covering these months is recommended.

In aquaculture, fish meal is the primary feed ingredient. The rapid expansion of the aquaculture industry drives up the demand for fish meal, leading to a rise in its price, which in turn escalates aquaculture’s operational costs. The purpose of this research is to evaluate water-based alternative protein sources as candidates for raw material feed in aquaculture. Microalga (Tetraselmis chuii, Spirulina platensis, and Chaetoceros calcitrans), biofloc, and klekap were evaluated using proximate analysis, amino acid analysis, and fatty acid analysis. The close study showed that the microalgae T. chuii meal (TcM), S. platensis meal (SpM), and biofloc meal (BFM) all had more than 20% protein and the same amount of amino acids as fish meal and soybean meal. BFM and C. calcitrans meal (CcM) contain essential fatty acids required by both freshwater (linoleic fatty acid) and marine fish (EPA and DHA). Meanwhile, TcM, which was the only raw material, contained linolenic acid but no DHA, whereas SpM and klekap meal (KM) contained only linoleic fatty acids.
