Authors: Swain Basudev , Vountas Marco , Singh Aishwarya , Gunthe Sachin S.
Published: November 2024

The rise in surface air temperature (SAT) in Venezuela, leading to the loss of all its glaciers, underscores the urgency of understanding human contributions to this phenomenon. This study investigates the impact of anthropogenic climate forcings on SAT across Venezuela, employing observational data, multi-model simulations, and optimal fingerprinting method. Anthropogenic forcings have driven a 0.40–0.85 $$^{\circ }$$

C) on SAT. Projections under Representative Concentration Pathways 4.5 indicate substantial SAT increases by the 21st century’s end, underscoring human-induced SAT rise. Effective management of regional Aaer and LU changes in Venezuela holds the potential for mitigating current and future warming and its subsequent impacts on the fragile ecosystem of this region.
Sustainable synthesis of fine chemicals and polymers using industrial chlorine chemistry
Authors: Kohsaka Yasuhiro , Matsuura Daisuke , Kimura Yoshikazu
Published: November 2024

To achieve sustainable resource circulation, preparation of reactive species from stable compounds is unavoidable. Chlorine chemistry is an eco-friendly methodology to address this demand. Chlorine is industrially produced from sodium chloride (NaCl), an abundant natural resource in oceans. Chlorine provides various chemical products, including polymers, through chlorination and subsequent conversion reactions. In these reactions, the byproducts are usually hydrogen chloride, which is commercially utilized as hydrochloric acid and is finally neutralized to NaCl after use. Therefore, chlorine chemistry enables fine chemical production from NaCl with almost no wastage. This review provides an overview of the synthesis of fine chemicals and polymers using chlorine chemistry and discusses them from the perspective of sustainability.

The presence of two new disinfectant by-product (DBP) groups in the UK was recently shown using non-target analysis, halogenated-hydroxycyclopentenediones and halogenated-methanesulfonic acids. In this work, we confirmed the structure of 2,2,4-tribromo-5-hydroxycyclopent-4-ene-1,3-dione (TBHCD), and quantified it together with dibromomethanesulfonic acid at 122 ± 34 and 326 ± 157 ng L−1 on average in London’s drinking water, respectively (n = 21). We found TBHCD to be photolabile and unstable in tap water and at alkaline pH. Furthermore, spectral and computational data for TBHCD and three other halogenated-hydroxycyclopentenediones indicated they could act as a source of radicals in water and in the body. Importantly, TBHCD was calculated to have a 14.5 kcal mol−1 lower C-Br bond dissociation enthalpy than the N-Br bond of N-bromosuccinimide, a common radical substitution reagent used in organic synthesis. TBHCD was mutagenic in Salmonella/microsome assays using strains TA98, TA100 and TA102. This work reveals the unique features, activity and toxicity of trihalogenated hydroxycyclopent-4-ene-1,3-diones, prompting a need to more comprehensively assess their risks.
Glacier surge as a trigger for the fastest delta growth in the Arctic
Authors: Kavan J. , Strzelecki M. C. , Benn D. I. , Luckman A. , Roman M. , Zagórski P.
Published: November 2024

The widespread retreat of Svalbard glaciers has been frequently interrupted by short-lived surge advances. In the case of marine-terminating glaciers this is often expressed in the remodelling of coastal zones. Here, we analyzed the coastal zone changes in front of the recently surging Recherchebreen. The glacier advanced ca 1200 m since 2018 and suddenly stopped in June 2020 followed by the rapid formation of a delta system in front of its subglacial meltwater outlet. The delta advanced by ca 450 m with probably the fastest progradation rate ever detected in the Arctic region (ca 7 m/day). The synchroneity of the final slow-down of the glacier with the delta building indicates that this event records the release of stored water and sediments from beneath the glacier and thus provides direct evidence of drainage reorganisation at the termination of a surge. Such behaviour is likely common among Svalbard surging glaciers, but it only rarely leaves any direct geomorphic evidence.

Published: November 2024

The evolution of SARS-CoV-2 variants with increased fitness has been accompanied by structural changes in the spike (S) proteins, which are the major target for the adaptive immune response. Single-particle cryo-EM analysis of soluble S protein from SARS-CoV-2 variants has revealed this structural adaptation at high resolution. The analysis of S trimers in situ on intact virions has the potential to provide more functionally relevant insights into S structure and virion morphology. Here, we characterized B.1, Alpha, Beta, Gamma, Delta, Kappa, and Mu variants by cryo-electron microscopy and tomography, assessing S cleavage, virion morphology, S incorporation, “in-situ” high-resolution S structures, and the range of S conformational states. We found no evidence for adaptive changes in virion morphology, but describe multiple different positions in the S protein where amino acid changes alter local protein structure. Taken together, our data are consistent with a model where amino acid changes at multiple positions from the top to the base of the spike cause structural changes that can modulate the conformational dynamics of the S protein.

Early detection is warranted to improve prognosis of gastric cancer (GC) but remains challenging. Liquid biopsy combined with machine learning will provide new insights into diagnostic strategies of GC. Lipid metabolism reprogramming plays a crucial role in the initiation and development of tumors. Here, we integrated the lipidomics data of three cohorts (n = 944) to develop the lipid metabolic landscape of GC. We further constructed the serum lipid metabolic signature (SLMS) by machine learning, which showed great performance in distinguishing GC patients from healthy donors. Notably, the SLMS also held high efficacy in the diagnosis of early-stage GC. Besides, by performing unsupervised consensus clustering analysis on the lipid metabolic matrix of patients with GC, we generated the gastric cancer prognostic subtypes (GCPSs) with significantly different overall survival. Furthermore, the lipid metabolic disturbance in GC tissues was demonstrated by multi-omics analysis, which showed partially consistent with that in GC serums. Collectively, this study revealed an innovative strategy of liquid biopsy for the diagnosis of GC on the basis of the serum lipid metabolic fingerprints.

Protein kinase A and local signaling in cancer
Authors: Rosenthal Kacey J. , Gordan John D. , Scott John D.
Published: November 2024

Protein kinase A (PKA) is a basophilic kinase implicated in the modulation of many cell-signaling and physiological processes. PKA also contributes to cancer-relevant events such as growth factor action, cell cycle control, cell migration and tumor metabolism. Germline and somatic mutations in PKA, gene amplifications, and chromosome rearrangements that encode kinase fusions, are linked to a growing number of malignant neoplasms. Mislocalization of PKA by exclusion from A-Kinase Anchoring Protein (AKAP) signaling islands further underlies cancer progression. This article highlights the influence of AKAP signaling and local kinase action in selected hallmarks of cancer. We also feature the utility of kinase inhibitor drugs as frontline and future anti-cancer therapies.
A techno‐enviro‐economic multi‐objective framework for optimal sizing of a biomass/diesel generator‐driven hybrid energy system
Authors: Akbarzadeh Amir , Askarzadeh Alireza
Published: November 2024

This article investigates multi‐objective size optimization of a hybrid energy system (HES) composed of biomass, photovoltaic (PV) and diesel generator considering technical, economic and environmental aspects. For this aim, two multi‐objective frameworks (techno‐economic and techno‐enviro‐economic) are developed where in the techno‐economic framework, total net present cost (TNPC) and loss of power supply probability (LPSP) are considered as the conflicting objectives. LPSP value is used as an index to measure the system reliability (by decrease of LPSP value, reliability will increase). In the techno‐enviro‐economic framework, net present cost of CO2 emission is also included in TNPC value. Furthermore, to determine the impact of biomass and diesel generator fuel costs on the Pareto front, a sensitivity analysis is conducted. Over the case study, simulated results show that in techno‐economic framework, at small values of LPSP, it is cost‐effective to use PV‐diesel rather than PV‐biomass system. In techno‐enviro‐economic framework, though at LPSP = 0, it is cost‐effective to use PV‐diesel system, in other levels of LPSP, it is desired to use PV‐biomass system.
CLASH-VLT: Galaxy cluster MACS J0329–0211 and its surroundings using galaxies as kinematic tracers

Context. The study of substructure is an important step in determining how galaxy clusters form.

Aims. We aim to gain new insights into the controversial dynamical status of MACS J0329–0211 (MACS0329), a massive cluster at z = 0.4503 ± 0.0003, through a new analysis using a large sample of member galaxies as kinematic tracers.

Methods. Our analysis is based on extensive spectroscopic data for more than 1700 galaxies obtained with the VIMOS and MUSE spectrographs at the Very Large Telescope (VLT) in combination with B and RC Suprime-Cam photometry from the Subaru archive. According to our member selection procedure, we defined a sample of 430 MACS0329 galaxies within 6 Mpc, corresponding to approximately three times the virial radius.

Results. We estimated the global velocity dispersion,
σV841-36+26

km s−1, and present the velocity dispersion profile. We estimated a mass of M200 = (9.2 ± 1.5)×1014 M⊙ using 227 galaxies within R200 = (1.71 ± 0.07) Mpc, for which
σV,200841-48+40

km s−1. The spatial distribution of the red galaxies traces a SE-NW elongated structure without signs of a velocity gradient. This structure likely originates from the main phase of cluster assembly. The distribution of the blue galaxies is less concentrated and more rounded, and it shows signs of substructure, all characteristics indicating a recent infall of groups from the field. We detected two loose clumps of blue galaxies in the south and southwest at a distance of ∼R200 from the cluster center. The strong spatial segregation among galaxy populations is not accompanied by a kinematical difference. Thanks to our extensive catalog of spectroscopic redshift, we were able to study galaxy systems that are intervening along the line of sight. We identified two foreground galaxy systems, GrG1 at z ∼ 0.31 and GrG2 at z ∼ 0.38, and one background system, GrG3 at z ∼ 0.47. We point out that the second brightest galaxy projected onto the MACS0329 core is in fact the dominant galaxy of the foreground group GrG2. MACS0329, GrG3, and two other systems detected using DESI DR9 photometric redshifts are close to each other, suggesting the presence of a large-scale structure.

Conclusions. MACS0329 is close to a state of dynamical equilibrium despite being surrounded by a very rich environment. We emphasize that the use of an extensive spectroscopic redshift survey is essential to avoiding misinterpretation of structures projected along the line of sight.

Aims. We carried out a project involving the systematic analysis of microlensing data from the Korea Microlensing Telescope Network survey. The aim of this project is to identify lensing events with complex anomaly features that are difficult to explain using standard binary-lens or binary-source models.

Methods. Our investigation reveals that the light curves of microlensing events KMT-2021-BLG-0284, KMT-2022-BLG-2480, and KMT-2024-BLG-0412 display highly complex patterns with three or more anomaly features. These features cannot be adequately explained by a binary-lens (2L1S) model alone. However, the 2L1S model can effectively describe certain segments of the light curve. By incorporating an additional source into the modeling, we identified a comprehensive model that accounts for all the observed anomaly features.

Results. Bayesian analysis, based on constraints provided by lensing observables, indicates that the lenses of KMT-2021-BLG-0284 and KMT-2024-BLG-0412 are binary systems composed of M dwarfs. For KMT-2022-BLG-2480, the primary lens is an early K-type main-sequence star with an M dwarf companion. The lenses of KMT-2021-BLG-0284 and KMT-2024-BLG-0412 are likely located in the bulge, whereas the lens of KMT-2022-BLG-2480 is more likely situated in the disk. In all events, the binary stars of the sources have similar magnitudes due to a detection bias favoring binary source events with a relatively bright secondary source star, which increases detection efficiency.

Published: November 2024

This study introduces a versatile grid-connected hybrid generation system designed to optimize the utilization of renewable energy sources, specifically wind and solar power. The system is engineered to supply power from these sources individually or simultaneously, depending on their availability. For wind energy, a Permanent Magnet Synchronous Generator coupled with a wind turbine regulates the mechanical output. Meanwhile, solar power generation depends on the operating voltage of the solar cells. The DC outputs from these renewable sources are seamlessly converted into AC power by an inverter, making it usable for the connected load. The system operates under typical room temperatures for solar energy and standard wind speeds in plain areas for wind energy. Its efficiency and robustness are further enhanced by a fuzzy-based Pulse Width Modulation (PWM) system, which effectively reduces harmonic ripples, thereby ensuring the delivery of high-quality AC power to the load. Comprehensive simulation results validate the system's operational principles, demonstrating its feasibility and reliability. This hybrid setup not only maximizes the utilization of renewable energy sources but also ensures a consistent and high-quality power supply, highlighting its potential for sustainable energy integration in modern power grids.

Biological processes are used to create AgNPs, which are thought to be economical, energy- efficient, and environmentally benign. One safe way to save energy and stay away from organic solvents is to make AgNPs through green synthesis. AgNPs are receiving a lot of attention in the wastewater management domain. The toxicity of heavy metals poses a significant risk of water contamination. AgNPs are useful substitutes for other methods in the removal of pollutants from wastewater bodies due to their improved adsorption capacities. Environmental removal of heavy metals can be significantly improved due to nanotechnology. Low detection and quantification limits, excellent sensitivity and selectivity are benefits of heavy metal removal from water resources using nanotechnology. Although a lot of study was taken up on release of silver nanoparticles (AgNPs) into wastewater and its probable toxicity to microorganisms, little work is taken up on heavy metals removal process. This investigation focused on the removal of heavy metals by
H.contortus leaf extract. Using the leaf extract, the removal capacities for Chromium (Cr[VI]), Copper (Cu[II]), Zinc (Zn([II]), Cobalt (Co[II]) and Manganese (Mn[II]) were 88.18%, 26.16%, 26.44%, 26.82% and 46.51% respectively. This demonstrates the stimulatory nature of AgNPs towards the heavy metal removal from wastewaters.

Published: November 2024

The load frequency control (LFC) is an important service in establishing the dynamic stability of the interconnected power system (IPS). Thus, this paper suggests the tilt-integral-derivative-filter (TIDF) using the water cycle algorithm (WCA) as the LFC regulator for the diverse sourced IPS, and the analysis is performed for 10% step load disturbance (SLD) on area 1. However, the efficaciousness of the TIDF controller performance is revealed with the performances of other controllers by performing the comparative analysis. Later, in order to attain the improvement in the system performance, a coordinated control approach of battery energy storage (BES) and a unified power flow controller (UPFC) is incorporated. The simulation analysis revealed the improvement in system performance to a considerable extent with the employment of the coordinated control strategy. The robustness of the proposed control strategy is finally validated by conducting the robustness test in terms of different loadings.

This paper presents a comprehensive study on the utilization of accelerometer sensors for structural health monitoring (SHM) in the assessment of polypropylene fiber-reinforced concrete (PFRC) performance. The incorporation of polypropylene fibers into concrete has shown promising potential in enhancing its structural integrity and durability. However, the accurate evaluation of PFRC behavior under varying conditions remains a critical aspect in ensuring its practical application in construction and infrastructure. In this research, I focus on employing advanced accelerometer sensor technology for real-time monitoring and assessment of PFRC performance. A series of experimental investigations have been conducted to capture and analyze the dynamic response and structural behavior of PFRC specimens subjected to different loading conditions as 200 kN, 400 kN, 600 kN, 800 kN & 1000 kN. The accelerometer sensors, strategically placed on the surface of the PFRC concrete with 1% of Fiber in Cubes, Cylinders and Beam elements provide precise data regarding vibration, deformation, and stress distribution, enabling a detailed evaluation of its mechanical properties and durability.

Comparative Study on hydration and Compressive strength of M20, M30 and M40 grades of self-compacting concrete and Normal Concrete
Authors: Abhinav K. Sai , Jawahar J. Guru
Published: November 2024

Concrete is the most generally involved development material in the advanced world. The strength of cement is a significant thought in its application in forceful conditions for long help life. Concrete incorporates a large amount of natural resources as aggregates and cement with water. Nowadays, the heat of hydration from concrete structures is the major environmental effect. During the intensity of hydration, concrete creates a high measure of Ca(OH)2 which is liable for heat. Hydration heat prompts the warm burdens in concrete during restoring which causes warm breaks by the temperature distinction among inside and external surfaces. Concrete creation likewise consumes tremendous energy and regular assets and causes around 7% of all out ozone depleting substance discharges on the planet. Hence, the utilization of supplementary cementitious materials such as fly ash, slag, and silica fume has been researched extensively over the last few decades to enhance the durability and sustainability of concrete. The proposed study is to reduce the heat of hydration of concrete using various admixtures. The expansion of these admixtures in concrete limits the Ca(OH)2 arrangement and accordingly lessens the intensity freedom in concrete without compromising the strength. The primary goal of this review is to screen the intensity of hydration of Self compacting concrete (SCC) with M20, M30 and M40 grade.. The hydration of concrete will be investigated by isothermal calorimeter. To monitor the temperature of concrete Thermo couples are used. The study also aims to develop the temperature-strength relationship model of various types of concrete. Proposals will be made on the choice of concrete for the economical climate.
