Authors: Setdikova G. R. , Verbovsky A. N. , Semenkov A. V. 
Published: December 2024

Introduction. According to the literature, the detection rate of laterally spreading tumors has increased in recent years due to the constant development of endoscopic diagnosis and treatment technologies. It is reported that these neoplasms account for about 15 % of all colorectal neoplasias. According to the literature, laterally spreading tumors are characterized by a more frequent presence of areas of malignancy compared to polypoid formations. Since such neoplasms are closely correlated with colorectal cancer, it is very important to fully understand the clinical presentation and morphological characteristics to select the optimal treatment strategy.Aim. The development of mapping of samples during morphological examination with subsequent correlation with endoscopic data and search for the most suitable areas for taking a biopsy.Materials and methods. To solve the problem described above, a mapping technology was developed for the morphological study of samples of laterally spreading colon neoplasia, which consists in creating an algorithm of actions, described in more detail in the work.Results. The first step of gross is the correct orientation of the resected specimen. The macroscopic integrity of the removed specimen is described. When describing microscopic data, the first question that the morphologist must answer is whether the process is benign or malignant. In case of malignant processes, the morphologist must answer according to the questionnaire: histological type, degree of differentiation / dysplasia, size (mm), depth of invasion, assessment of resection margins, lymphovascular and perineural invasion, tumor kidneys.Conclusion. The presented technique, when used in everyday pathological practice for neoplastic neoplasms of the colon, can allow a reliable assessment of all prognostic factors and the development of an objective interdisciplinary consensus for further treatment.
The South Island Seismology at the Speed of Light Experiment (SISSLE): Distributed Acoustic Sensing Across and Along the Alpine Fault, South Westland, New Zealand
Authors: Miller Meghan S. , Townend John , Lai Voon Hui 
Published: December 2024

Abstract
Distributed acoustic sensing (DAS) is positioned to revolutionize observational seismology by providing dense spatial sampling and temporal resolution. DAS repurposes long sections (1–10s of kilometers) of fiber-optic cable into thousands of individual sensors at meter spacing and uses light to measure the ground motion as seismic waves pass through the fiber. The South Island Seismology at the Speed of Light experiment involved the acquisition of DAS data from two dark telecommunication fibers along the highway near Haast, South Westland, New Zealand that run perpendicularly across the Alpine Fault and subparallel to the Alpine Fault and Tasman Sea coastline. The DAS acquisition was supplemented by the deployment of 24 nodal seismometers within 1 km of the surface trace of the Alpine Fault. We introduce the experimental setup, share initial processing steps, and preliminary observations from the DAS array deployed in two phases for nearly five months between late-February and mid-May 2023 and again in October–November 2023.

Abstract
Earthquake location programs employ diverse approaches to address the challenges posed by incomplete knowledge and simplified representation of complex Earth structures. Assessing their reliability in location and uncertainty characterization remains challenging as benchmark datasets with known event locations are rare, and usually confined to particular sources, such as quarry blasts. This study evaluates eight earthquake location methods (GrowClust, HypoDD, Hypoinverse, HypoSVI, NonLinLoc, NonLinLoc_SSST, VELEST, and XCORLOC) through a controlled synthetic computational experiment on 1000 clustered earthquakes based on the setting of the 2019 Ridgecrest, California, earthquake sequence. We construct a travel-time dataset using the fast-marching method and a 3D velocity model extracted from the Community Velocity Model, supplemented with a von Karman perturbation to represent small-scale heterogeneity, and including elevation effects. Picking errors, phase availability, and outliers are introduced to mimic difficulties encountered in seismic network monitoring. We compare the location results from eight programs applied to the same travel-time dataset and 1D velocity structure against the ground-truth locations. For this aftershock sequence, our results reveal the superior accuracy and precision of differential time-based location methods compared to single-event location methods. The results validate the significance of compensating for deviations from assumed 1D velocity structure either by path or site correction modeling or by cancellation of unmodeled structure using differential arrival times. We also evaluate the uncertainty quantification of each program and find that most of the programs underestimate the errors.

Published: December 2024

Crown root fractures of anterior teeth are complex dental injuries that present unique challenges due to the involvement of both the crown and root structures. These fractures often lead to concomitant periodontal injury, which can complicate the treatment outcome. Additionally, anterior fractures pose aesthetic and psychological concerns for the patient. Reattachment or restorative repair of fractures involving the coronal third of the root are notoriously prone to failure due to their proximity to the oral cavity leading to difficulty in isolation and bacterial contamination. Sub crestal fracture lines may also encroach the biological width complicating the management further.This case report details the clinical presentation of a patient with an anterior crown root fracture with the fracture line extending below the alveolar crest and was managed non-conventionally using Biodentine.

Najbardziej ekologicznym paliwem kopalnym jest gaz ziemny, który charakteryzuje się niską emisją CO2 i brakiem zanieczyszczeń pyłami podczas jego spalania. Obecnie w Polsce eksploatowanych jest siedem podziemnych magazynów gazu, które stanowią część systemu gazowniczego. Pięć z nich zostało utworzonych w sczerpanych złożach gazu ziemnego, a dwa w kawernach solnych. Do podstawowych zadań podziemnych magazynów gazu należą m.in. zaspokajanie skokowego zapotrzebowania na gaz w sezonie zimowym, możliwość optymalizacji systemu gazowniczego oraz pełnienie roli rezerw strategicznych. Jednakże przeprowadzone ostatnio analizy wykazały, poprzez porównanie pojemności czynnej krajowych magazynów ze średnią z krajów unijnych, że obecne pojemności podziemnych magazynów gazu w Polsce nie są wystarczające i powinny zostać rozbudowane do 7,56 mld m3. W artykule został przedstawiony projekt koncepcji rozbudowy pojemności czynnej wirtualnego podziemnego magazynu gazu, który pozwoli na jej powiększenie do 130% aktualnej pojemności czynnej. W pracy wykonano cyfrowy model symulacyjny 3D za pomocą programu JewelSuite 6.2 firmy Baker Hughes wraz z modelem rozkładu przestrzennego facji oraz modelami parametrycznymi, takimi jak model rozkładu przestrzennego współczynnika porowatości i przepuszczalności geofizycznej, oporności elektrycznej oraz współczynnika porowatości neutronowej, co pozwoliło na wybór optymalnego miejsca na odwiercenie nowych otworów eksploatacyjnych, niezbędnych do zatłoczenia i odebrania nowej pojemności czynnej. W koncepcji określono wielkość pojemności czynnej możliwej do uzyskania, zakładając górne ciśnienie pracy instalacji nieprzekraczające 8,32 MPa, oraz podano podstawowe parametry magazynu po jego rozbudowie do 130% aktualnej pojemności czynnej. W artykule zaproponowano wykonanie pięciu nowych odwiertów horyzontalnych. Ponieważ odwierty horyzontalne charakteryzują się na ogół lepszą wydajnością niż odwierty pionowe, to taka liczba nowych odwiertów pozwoli na odebranie nowej pojemności czynnej w czasie 122 dni.

The utilisation and processing of crude oil sludge is one of the major global challenges. Therefore, it is necessary to justify the following scientific solutions in the field of oil sludge utilisation and processing worldwide: the study of the physicochemical properties of oil sludge in order to obtain construction grade bitumen; detection of dispersion of solid particles in the composition of oil sludge; development of the optimal technological parameters for the process of obtaining construction grade bitumen from oil sludge; establishing a correlation dependence between process efficiency and the environment, the content of light fractions in the sludge composition, the process temperature. In this work, oil sludge was diluted with a solvent in a ratio of 70:30, with light naphtha used as a solvent. A laboratory distillation column was used to separate the sludge into fractions, and the chemical composition of the oil sludge was investigated. Oil sludge consists of asphaltenes up to 4.2–4.5%, resins up to 21.0%; paraffin-naphthenic hydrocarbons up to 41.2%; monocyclic aromatic hydrocarbons up to 4.6%; bi- and tricyclic aromatic hydrocarbons up to 5.8%; polycyclic aromatic hydrocarbons up to 9.7%. The paper also presents the results of the change in the viscosity and density of the distillate fractions separated during the distillation of diluted oil sludge. Density and viscosity were measured using an areometer and a VPZh-4, respectively. One of the main components of the oil sludge is water. A series of experiments were conducted to determine the water content using the Dean and Stark method. In addition, the sulphur content in oil sludge diluted with solvents – light and heavy naphtha, heavy gas oil – was determined.
Le revenu agricole des agriculteurs et des éleveurs en France : une forte variabilité interannuelle (2010-2022) et de grandes disparités
Authors: CHATELLIER Vincent 
Published: December 2024

En utilisant les données du Réseau d’information comptable agricole (RICA) sur la période 2010 à 2022, cet article présente une analyse de l’évolution des revenus des exploitations agricoles françaises et de leur dispersion. L’indicateur utilisé pour en rendre compte est le résultat courant avant impôt (RCAI) par unité de travail agricole (UTA) non salariée. Dans un premier temps, l’analyse est conduite toutes orientations de production confondues. Elle met en évidence une forte variabilité interannuelle du revenu moyen des agriculteurs français, avec un pic à 55 800 euros en 2022 et un creux à 21 300 euros en 2016 (pour une moyenne de 34 100 euros par an sur la période 2010-2022). Une grille typologique distinguant 64 cases est ensuite proposée pour démontrer l’influence de trois indicateurs essentiels sur le niveau des revenus, à savoir « la productivité du travail », « l’efficience productive » et « la capacité de l’exploitation à faire face à ses engagements financiers ». Dans un deuxième temps, l’analyse est menée selon les orientations de production. Tout en rendant compte des écarts internes à chacune d’elles, ce travail démontre que le revenu moyen dégagé dans les exploitations spécialisées en productions de ruminants est, dans une approche de long terme, clairement inférieur à celui obtenu dans d’autres orientations de production telles que les grandes cultures, la viticulture ou la production porcine. En combinant les trois indicateurs précités, une méthode permet enfin de répartir les exploitations bovins-lait et bovins-viande selon huit classes dites de « performances économiques ».
Isolation and Characterization of a Roseophage Representing a Novel Genus in the N4-like Rhodovirinae Subfamily Distributed in Estuarine Waters
Authors: Huang Xinyu , Chen Yu , Lu Longfei 
Published: December 2024

Abstract

Background
Roseobacteraceae, often referred to as the marine roseobacter clade (MRC), are pivotal constituents of bacterial communities in coastal and pelagic marine environments. During the past two decades, 75 roseophages that infect various Roseobacteraceae lineages have been isolated. The N4-like Rhodovirinae subfamily, which encompasses 15 members, represents the largest clade among these roseophages.
Results
In this study, we isolated a novel roseophage, vB_DshP-R7L, that infects Dinoroseobacter shibae DFL12 from Xiamen Bay in the East China Sea. Conserved genes of Schitoviridae have been identified in the genome of vB_DshP-R7L, and following phylogenetic analysis suggest that the newly isolated phage is a member of the Rhodovirinae subfamily and is indicative of a newly proposed genus, Xianganvirus. The genome of vB_DshP-R7L harbors six auxiliary metabolic genes (AMGs), most of which potentially enhance DNA de novo synthesis. Additionally, a gene encoding ribosomal protein was identified. Comparative genomic analysis of AMG content among Rhodovirinae indicates a distinct evolutionary history characterized by independent ancient horizontal gene transfer events. Read-mapping analysis reveals the prevalence of vB_DshP-R7L and other Rhodovirinae roseophages in estuarine waters.
Conclusions
Our work illustrates the genomic features of a novel roseophage clade among N4-like Rhodovirinae. The AMG content of vB_DshP-R7L are under severe purification selection, which revealed their possible ecological importance. We also demonstrated that vB_DshP-R7L and other Rhodovirinae roseophages are restrictively distributed in estuaries. Our isolation and characterization of this novel phage expand the understanding of the phylogeny, gene transfer history and biogeography of N4-like Rhodovirinae infecting marine Roseobacteraceae.

Abstract

Background
In recent efforts to address the critical need for clean and portable water, we have focused on innovative methods to eliminate pathogenic microorganisms. To this aim, the Glycyl-L-leucine peptide ligand was complexed with different transition metal ions [Cu(II), Ni(II), and Cd(II)]. The compounds were characterized and examined using various analytical methods, including elemental analysis (CHN), Fourier transform infrared spectroscopy (FTIR), and assessments of magnetic properties, molar conductivity, and thermogravimetric analysis. An N2O2 arrangement of ligand atoms coordinated all metals. The coordination sites were completed with a carbonyl oxygen atom and a water molecule. The complexes showed polymeric structures using bridging carboxylate groups.
Results
Their antibacterial properties were screened using disc diffusion and minimum inhibitory concentrations techniques against the identified bacterial organisms from the water samples collected along the Nile River. Cu(II)-chelate showed the best results for our investigation. The docking results supported and displayed that Cu(II)-chelate exhibited the minimum binding energy as compared to Ni(II), Cd(II), and free peptide which is in agreement with antibacterial results.
Conclusions
our study successfully demonstrated the potential of Glycyl-L-leucine peptide ligands complexed with transition metal ions, particularly Cu(II), in eliminating pathogenic microorganisms from water. Cu(II)-chelate exhibited superior antibacterial properties, as confirmed by both experimental and molecular docking results. This compound not only showed the lowest binding energy but also proved to be the most effective against bacterial and viral targets. These findings highlight the promising application of Cu(II)-chelate in developing advanced water purification systems.

Abstract

In winemaking, wood products alternative to barrels are used to achieve various oenological goals, including rapid release of desirable volatile and polyphenolic compounds, color stabilization, and economic benefits. In this research study, oak wood formats (staves, cubes, and chips) were added to red Nebbiolo wines at two vinification stages: during and after alcoholic fermentation. Aromatic composition was analyzed at racking off, after three and seven months of aging. Samples were analyzed by gas chromatography–mass spectrometry (GC–MS) and gas chromatography-flame ionization detector (GC-FID). After seven months, a trained panel assessed the sensory profiles of the wines who varied significantly based on the timing of wood addition and the type of wood used. Higher levels of vanillin and furan compounds were found in wines with wood added after fermentation and in those treated with staves. Wines treated with cubes had elevated benzoic aldehyde levels, while those with chips showed higher levels of whisky lactone, a key molecule for "boisé" notes. Sensory analysis revealed greater intensity of vanilla and oak wood descriptors in wines treated with cubes and chips. Cubes particularly enhanced spicy aromas like cloves and pepper, offering a more balanced aroma and sensory profile compared to staves and chips.

Abstract

The photocatalysis-based technology has an insight into decreasing the disadvantages of those traditional approaches and is identified as an appropriate way to eliminate dyes and bacteria from wastewater. In this work, Fe3O4/rGO/TiO2 photocatalyst material was synthesized by a simple and fast hydrothermal method. The photocatalyst process results showed that Fe3O4/rGO/TiO2 nanocomposite degraded methylene blue dye completely in 4 min. Also, Fe3O4/rGO/TiO2 nanocomposite was very efficient (4.92 log reduction value) for E. Coli bacteria inactivation in 60 min photocatalyst process. The superparamagnetic behavior of Fe3O4/rGO/TiO2 nanocomposite was investigated by VSM analysis which gives simple and fast separation from media to Fe3O4/rGO/TiO2 nanocatalyst. The structural and morphology properties of Fe3O4/rGO/TiO2 nanocomposite were studied by XRD, Raman, FT-IR, EDS, FESEM, and TEM analysis. The obtained results confirmed that Fe3O4/rGO/TiO2 nanocomposite is an efficient nanocatalyst for MB dye removal and water disinfection.

Published: December 2024

Abstract

Background: Biocatalysis offers a potentially greener alternative to chemical processes. For biocatalytic systems requiring cofactor recycling, hydrogen emerges as an attractive reducing agent. Hydrogen is attractive because all the electrons can be fully transferred to the product, and it can be efficiently produced from water using renewable electricity. In this article, resting cells of Cupriavidus necator H16 harboring a NAD-dependent hydrogenase were employed for cofactor recycling to reduce D-xylose to xylitol, a commonly used sweetener. To enable this bioconversion, D-xylose reductase from Scheffersomyces stipitis was heterologously expressed in C. necator.
Results: D-xylose reductase was successfully expressed in C. necator, enabling complete bioconversion of 30 g/L of D-xylose into xylitol within 7 days using resting cells. It was found that over 90% of the energy and protons derived from hydrogen were spent for the bioconversion, demonstrating the efficiency of the system. The highest xylitol productivity reached was 0.7 g L-1 h-1. Additionally, the same chassis efficiently produced L-arabitol and D-ribitol from L-arabinose and D-ribose, respectively.
Conclusions: This study highlights the efficient utilization of renewable hydrogen as a reducing agent to power cofactor recycling. Hydrogen-oxidizing bacteria, such as C. necator, can be promising hosts for performing hydrogen-driven biocatalysis.

Abstract

In this contribution, well-known poly(ԑ-caprolactone-b-4-vinylbenzyl-g-ethyleneglycol) [poly(ԑ-CL-b-VB-g-EG)] block-graft terpolymer was prepared via reversible addition/fragmentation chain transfer (RAFT), ring-opening polymerization (ROP) and “click” chemistry methods. For this purpose; in the first part, a RAFT-ROP agent was obtained by the reaction of 3-chloro-1-propanol and ethylxanthic acid potassium. In the second part, poly(ԑ-caprolactone-b-4-vinyl benzyl chloride) [poly(ԑ-CL-b-VBC)] block copolymer was prepared by RAFT polymerization of 4-vinyl benzyl chloride, and ROP of ԑ-caprolactone using synthesized a RAFT-ROP agent in the one-step. In the third part, poly(ԑ-caprolactone-b-4-vinyl benzyl chloride-N3) [poly(ԑ-CL-b-VB-N3)] was obtained by reaction of the poly(ԑ-CL-b-VBC) block copolymer and NaN3. On the other hand, alkyne-terminated PEG (PEG-propargyl) was acquired via the reaction of polyethylene glycol (PEG-3000) with propargyl chloride. Finally, poly(ԑ-CL-b-VB-g-EG) block-graft terpolymer was prepared from the reaction PEG-propargyl and poly(ԑ-CL-b-VB-N3) via the grafting to "click" chemistry method. The structure of the final products was characterized by instruments such as GPC, 1H-NMR, FT-IR, TGA, DSC and SEM.
