Charcoal briquettes made from a mixture of alaban charcoal and coconut shell are one of the efforts to utilize waste. The purpose of this study was to determine the variation of the mixture of alaban charcoal powder and coconut shell on the quality of charcoal briquettes. The mixture of raw materials uses 5 variations, namely 1) 100% charcoal; 2) 75% alaban charcoal and 25% coconut shell; 3) 50% alaban charcoal and 50% coconut shell, 4) 25% alaban charcoal and 75% coconut shell; and 5) 100% coconut shell. The resulting data were then analyzed by variance and compared with ASTM. The quality of charcoal briquettes is not affected by the composition of the mixture of alaban charcoal and coconut shell. Treatment with 100% coconut shell raw materials, without a mixture of alaban charcoal, is charcoal briquettes with the quality closest to ASTM standards, in the form of ash content, volatile matter, calorific value. Other parameters such as water content, density and bound carbon still do not meet ASTM standardsBriket arang terbuat dari campuran arang alaban dan tempurung kelapa adalah salah satu upaya salah satu upaya pemanfaatan limbah.

DIFFERENTIATION OF TYPES OF INDIRECT DIRECTIVE SPEECH ACT IN GERMAN DIALOGICAL DISCOURSE
Authors: Buivol Oleg 
Published: June 2023

The problems of professional communication are revealed, which in the modern period of human development have become the most urgent problems of applied linguistics. Over the past two decades, such a scientific and theoretical discipline as terminography has appeared. It is substantiated that information technologies are developing so rapidly due to the formation of new terms that organizing this process and responding appropriately to all existing changes in the terminological field is a very difficult task. It is proved that for successful work on overcoming these problems, a clear structured organization of computer vocabulary should be carried out. The components of the computer language are revealed: terminology (literary and non-literary vocabulary (professionalisms and jargons are stylistically expressive and perform an emotional and evaluative function). Each of these lexical layers has its own specific features, range of functioning and scope. The main purpose of computer terminology is considered - the identification of specific components
of information technology, as well as the structure of the terminological system, which corresponds to the specifics of
this field of science, and its components that enter into the relationship of antonymy, homonymy and polysemy.

Diffusive Leakage Through Existing and/or Induced Microfractures in the Caprock of CO2 Storage System
Authors: Das Ayon Kumar , Hassanzadeh Hassan 
Published: June 2023

Summary
Safe sequestration of CO2 in subsurface formations requires a caprock that inhibits the unwanted flow of the stored fluids. However, the preexisting fractures and the induced fractures initiated by overpressure and thermal stresses may act as potential leakage pathways. In this study, we describe a physical problem where the caprock with tiny embedded microfractures is subjected to overpressurization at the storage layer. The average effect of the existing and induced fractures is accounted for by employing a spatially variant permeability field. Also, the alteration of effective local stress is considered by applying Pedrosa’s stress-sensitive model. The coupled model for the pressure diffusion in the caprock and monitoring aquifer is solved using a general Bessel function solution and Laplace transform. The nonlinearity due to stress sensitivity was attenuated by Pedrosa’s transform, and a perturbation solution was obtained. The obtained solution was verified analytically and compared against classical solutions. The spatial variability of the caprock permeability field is effectively represented by the caprock’s two endpoint permeability values, storage/caprock interface permeability, and caprock/monitoring aquifer interface permeability. The ratio between the caprock’s two endpoint permeability values, intactness ratio, is observed to decrease with the increase in the permeability modulus, indicating permeability enhancement due to pressure buildup in the caprock. We identified that the temporal change in the spatially variant permeability field due to stress sensitivity is negligible. The results revealed that all averaging methods underestimate the pressure inside the caprock compared to a spatially variant case. This underestimation is minimum at the interface of caprock and monitoring formation for the harmonic average. The pressure evolution in the monitoring aquifer shows an overestimation of pressure when arithmetic and geometric average permeabilities are considered, while the results obtained using a harmonic average are similar to those of the spatially variant case. The reported work is unique as it accounts for pressure diffusion through preexisting and induced fractures and provides a coupled solution for pressure evolution in monitoring aquifers. This analytical model can be extended for double porosity formations.
Dephasing dynamics accessed by high harmonic generation: Direct determination of quantum decoherence

Published: June 2023

Abstract
We reveal the critical effect of ultrafast quantum dephasing on the polarization of high harmonic generation from massless Dirac fermions in graphene. Under the elliptically polarized pump pulse, the elliptically polarized high harmonic generation is produced and exhibits a characteristic polarimetry of the polarization ellipse, which is found to depend on the decoherence time T2 for the dephasing in the multiphoton regime. T2 could then be determined to be a few femtoseconds directly from the experimentally observed polarimetry of high harmonics. This shows a sharp contrast with the semimetal regime of higher pump intensity, where the polarimetry is irrelevant to T2. An access to the dephasing dynamics would extend the prospect of high harmonic generation into the metrology of femtosecond dynamical process in the coherent quantum control.
Higher evolutionary dynamics of gene copy number for Drosophila glue genes located near short repeat sequences
Authors: Monier Manon , Nuez Isabelle , Borne Flora , Courtier-Orgogozo Virginie 
Published: June 2023

Abstract
Background
During evolution, genes can experience duplications, losses, inversions and gene conversions. Why certain genes are more dynamic than others is poorly understood. Here we examine how several Sgs genes encoding glue proteins, which make up a bioadhesive that sticks the animal during metamorphosis, have evolved in Drosophila species.
Results
We examined high-quality genome assemblies of 24 Drosophila species to study the evolutionary dynamics of four glue genes that are present in D. melanogaster and are part of the same gene family - Sgs1, Sgs3, Sgs7 and Sgs8 - across approximately 30 millions of years. We annotated a total of 102 Sgs genes and grouped them into 4 subfamilies. We present here a new nomenclature for these Sgs genes based on protein sequence conservation, genomic location and presence/absence of internal repeats. Two types of glue genes were uncovered. The first category (Sgs1, Sgs3x, Sgs3e) showed a few gene losses but no duplication, no local inversion and no gene conversion. The second group (Sgs3b, Sgs7, Sgs8) exhibited multiple events of gene losses, gene duplications, local inversions and gene conversions. Our data suggest that the presence of short "new glue" genes near the genes of the latter group may have accelerated their dynamics.
Conclusions
Our comparative analysis suggests that the evolutionary dynamics of glue genes is influenced by genomic context. Our molecular, phylogenetic and comparative analysis of the four glue genes Sgs1, Sgs3, Sgs7 and Sgs8 provides the foundation for investigating the role of the various glue genes during Drosophila life.
Experimental and Theoretical Evidence Pointing to a Possible Classical Value to Elementary Electric Charge
Authors: Williams Lamont 
Published: June 2023

Abstract

It is well known that electric and magnetic phenomena are closely related. It is also well established that the electron magnetic moment has a classical and quantum value, in which the quantum value is the classical value times a particular number, approximately 1.0012, that accounts for quantum mechanical effects. This study explores the possibility that elementary electric charge (e) also has a classical and quantum value. Data from experiments, as well as a quark-based theoretical study, that identified dual values for e were evaluated. Results show that across the studies, there was a surprisingly consist appearance of a factor of about 1.0015 (or some power of the number) by which the lower value of e in the studies needed to be multiplied to equal the higher value. This suggests that the lower value in each study was reflective of a classical e value, while the higher number began to account for quantum effects, with 1.0015 possibly being an anomalous factor associated with the two values. Interpretations of the findings are presented showing how the study results possibly lead to a fundamental equation for the fine-structure constant and provide plausible solutions to the Landau pole and quantum triviality problems of quantum electrodynamics, which are currently persistent complications in that theory.

Published: June 2023

Abstract
PURPOSE:
To explore the efficacy and safety of local injections of dexamethasone into the lateral rectus muscle for treatment of acute idiopathic abducens nerve palsy (AIANP).
METHODS:
A study group and a control group were established for this study. The former received dexamethasone injections into the paralyzed lateral rectus muscle in combination with oral mecobalamin tablets. The control group only received mecobalamin tablets for no more than two months. The follow-up period was > 6 months. Incidence of lateral rectus palsy and diplopia were recorded, as well as complications.
RESULTS:
Between September 2019 and September 2022, a total of 72 patients with AIANP were included in this study (mean age: 54.1 ± 15.8 y). After treatment, all 39 patients in the study group were successfully treated (100%), while only 27/33 (81.8%) patients in the control group were successfully treated. This difference between groups was statistically significant (Fisher’s exact test, P = 0.01). Recovery times for the two groups also differed (3.45 ± 1.49 weeks vs. 12.1 ± 9.83 weeks, respectively; P < 0.001). Among the two groups, only one case of conjunctival congestion was reported at the injection site in the treatment group. Furthermore, recurrence was not observed during the follow-up period (17.9 ± 8.17 months).
CONCLUSION:
Dexamethasone injections into the lateral rectus muscle of AIANP patients are found to be a safe and effective treatment. They also improved the treatment rate and shortened treatment time．
Is Fucus a Suitable Biomonitoring Organism for Polycyclic Aromatic Hydrocarbon Contamination? A Study from the Faroe Islands

Published: June 2023

Abstract

This study aimed to evaluate seaweed as a novel biomonitoring organism for polycyclic aromatic hydrocarbon (PAH) pollution in the Faroe Islands. Fucus samples were collected from two cities and two towns. 19 PAHs, including the EPA 16, and four groups of alkylated PAHs, were quantified using GC-MS analysis. PAHs were extracted using a modified QuEchERS method with ultrasonication in acetonitrile, back-extraction into hexane and Florisil® cleanup. Fucus from the harbor of Tórshavn sampled at high tide had the highest PAH concentrations (1.3∙102 to 1.7∙102 ng/g wet weight), with the highest ∑PAH concentrations and abundance of individual PAHs found in Tórshavn, followed by Runavík and Toftir. All samples contained higher concentrations of alkylated PAHs compared to the non-alkylated compounds. The study found that Fucus may be promising as a biomonitoring organism for PAH pollution; however, major differences among samples collected in close proximity and on different days were observed, suggesting that water exchange and tide levels have a strong influence on pollutant uptake in Fucus. Therefore, further evaluation of sampling strategy is necessary. Overall, this study provides important insights into the use of Fucus as a biomonitoring organism for PAH pollution.

Abstract
The rewetting of formerly drained peatlands is a strategy to fight against global warming through the reduction of CO2 emissions, although this can lead to elevated CH4 emissions. The interplay between plants, hydrology and microbiomes as ultimate determinants of CH4 dynamics is still poorly understood, despite recent progress in field studies. Using a mesocosm approach, we simulated the re-cultivation of a degraded temperate fen with three different water levels and two different plant over the course of a growing season. Peat samples for microbiome analysis, above- and below-ground plant biomass and gas fluxes were measured in April, June, August and October. Microbiome composition in top and subsoils was determined using 16S rRNA gene amplicon sequencing. We found that peat depth and sampling time were the major factors shaping the microbiome composition dynamics. While plant species had a less strong impact, the difference to bare ground microbiomes was significant, especially in the lower layer. The water status also affected the microbiome, albeit to a much lesser extent. Methanogens were most abundant in the deeper peat and also more abundant in bare ground and Carex rostrata pots, as compared to Juncus inflexus or mixed pots. This was inversely linked to the larger root network size of J. inflexus. The methane emissions correlated positively with the abundance of methanogens and correlated negatively with the root network size. Despite the absence and low abundance of methanotrophs in many samples, the structural equation model suggested that the methanogen and methanotroph abundances together determined CH4 fluxes. In conclusion, this interdisciplinary study sheds light on how the complex interplay between plants, hydrology and the fen microbiome affect CH4 emissions. It showed that the presence of plants as well as the plant functional type determine the abundance of methanogens and microbiome composition and thereby the resulting CH4 fluxes accordingly.

Published: June 2023

Abstract
Iron-supported zeolite has shown great potential as an efficient catalyst for degrading organic pollutants with high concentrations in the catalytic wet peroxide oxidation (CWPO) process under mild conditions. Here 0.4 wt.% La was added in the 1.0 wt.% Fe-ZSM-5 by two-step impregnation method for an enhanced H2O2 utilization efficiency. For a systematical comparison, the CWPO process under 55°C, where m-cresol with a high concentration of 1000 mg/L as a substrate, was studied over Fe-ZSM-5 and Fe-La-ZSM-5 catalysts. Compared with Fe-ZSM-5, Fe-La-ZSM-5 showed 15% higher H2O2 utilization efficiency with comparable TOC removal at around 40%, meanwhile with a 15% reduced metal leaching. Transmission electron microscopy (TEM) with EDS mapping, surface acidity analysis by Fourier Transform InfraRed (FT-IR) and NH3-Temperature Programmed Desorption (NH3-TPD), redox property analysis by Raman spectroscopy and H2-Temperature Programmed Reduction (H2-TPR) of both catalysts revealed, a altered surface acidity, a more uniform and evenly dispersed surface Fe species with a promoted reducibility, which effectively prevented the ineffective decomposition of H2O2, enhanced the H2O2 utilization efficiency, and increased the catalyst stability. Also, more than 90% conversion of 1000 mg/L m-cresol for more than 10 consecutive test days under 55°C without pH adjustment showed a promising possibility of the Fe-La-ZSM-5 for a practical wastewater treatment process.

Published: June 2023

Abstract
Background
The non-invasive PET imaging using zrconium-89 labelled antibodys (Abs) can play important roles for personalized immunotherapeutic strategies. Hu4G4 was a humanized Abs of the transmembrance glycoprotein B7-H3, which has been approved as an attractive new target of cancer immunotherapy. This study aimed to investigate the PET imaging potential of 89Zr labelled hu4G4 with a dose escalation design.
Methods
Hu4G4 was radiolabelled with 89Zr after modification with p-SCN-deferoxamine. 89Zr-Immuno-PET scans of the U87 xenograft mice were performed with 3 different Abs doses of 89Zr-DFO-hu4G4 (0.33, 1.75 and 17.5 mg/kg bodyweight, respectively). The pharmacokinetic (PK) and biodistribution profiles were also determined by γ counting of blood samples and dissected organs and tissues.
Results
The prepared 89Zr-DFO-hu4G4 had high radiochemical purity (RCP > 95%) and was stable in vitro (RCP > 90% within 168 h). The U87 tumors were clearly detected by the 89Zr-DFO-hu4G4 PET imaging. The middle-dose Abs group had higher tumor-to-normal tissue (T/N) ratios and better tumor specific uptake of the tracer than the low and high dose Abs groups.
Conclusion
89Zr-DFO-hu4G4 is a potential immunoPET imaging probe for clinical detection of B7-H3 expression in tumor. Also, the dose dependent results of 89Zr-immuno-PET imaging provide important insight towards the Abs dosimetry for Abs-based imaging and therapy.

Published: June 2023

Abstract
In this work, we theoretically explore how litter decomposition processes and soil-borne pathogens contribute to negativeplant-soil feedbacks, in particular in transient and stable spatial organisation of tropical forest trees and seedlings known asJanzen-Connell distributions.
By considering soil-borne pathogens and autotoxicity both separately and in combination, we can understand the influence ofboth factors on transient dynamics and emerging Janzen-Connell distributions. We also identify parameter regimes associatedwith different long-term behaviours. Moreover, we compare how the strength of negative plant-soil feedbacks was mediated bygermination and growth strategies, using a combination of analytical approaches and numerical simulations.
Our interdisciplinary investigation, motivated by an ecological question, allows us to construct an important link between localfeedbacks, spatial self-organisation, and community assembly, providing a valuable tool to help understanding biodiversity intropical ecosystems and disentangling the differences between two potential mechanisms driving Janzen-Connell distributions.Furthermore, our theoretical results may help guiding future field data analyses by identifying spatial signatures in adult treeand seedling distribution data that may reflect the presence of particular plant-soil feedback mechanisms.

Published: June 2023

Abstract
Objective: To investigate whether gestational specific trends present in blood pressure (BP) and we also
special interested in the advanced maternal age women BP characteristics.
Design: A cohort study of clinical data.
Participants: We enrolled 287 pregnant women of 15,430 screened, containing 228 of younger age
pregnant women (<35 years old when pregnant) and 59 advanced maternal age participants (≥35 years
old when pregnant). Every included participant was nulliparous, has pregnant blood pressure records (≥5
times) and complete recommanded imformation.
Interventions: None.
Results: In the younger age pregnant group, the lowest of systolic BP appears at 14-18 weeks gestation
and the maximum was at 37-41+6 weeks’ gestation. In the advanced maternal age group, the lowest value
of systolic and diastolic BP both appeared at 14-18 weeks gestational age and rised to maximum BP at 37-41+6 weeks gestational age. Except for the last gestational stage of pregnancy, systolic BP numbers
are higher in the advanced age group (19-23 weeks, 24-27 weeks, 33-36 weeks, P<0.05).
Conclusions: We found that the advanced age women pregnant have similar gestational BP trends with
to the younger age group but with higher values of systolic BP at the most of the gestational time.
