Truth and mass terms

Helical flow of hot plasma gas, e.g., hydrogen gas, produced by a gas vortex stabilized plasma arc is cancelled by introducing attenuating gas, e.g., hydrogen gas, into the hot plasma gas in a manner such that the attenuating gas assumes a vortical direction opposite to the helical flow of the hot plasma gas. The resulting gas stream is well-collimated. The well-collimated plasma gas stream is used in the preparation of finely-divided refractory metal and metalloid carbides, borides, nitrides, silicides and sulfides. Reactants for the preparation of the aforementioned refractory powders are introduced into the collimated plasma gas stream. The reaction is conducted in the gas phase within a reactor and solid, finely-divided refractory powder removed from the reactor.
THE EFFECTIVENESS OF THE RADON TRANSFORM AGAINST THE QUANTIZATION NOISE

The aim of image compression consists to reduce the number of bits required to represent an image. The Radon transform has become a very interesting tool in the field of image processing. Its Robustness against noises such as white noise has boosted the researchers to realize methods of detection of objects in noisy images. The Discrete Cosine Transform has shown its efficacy in the energy compaction of the image to be compressed into a smaller number of coefficients. It is part of many international standards including JPEG and MPEG. In this paper, we present an image compression method, which is the modification of the scheme presented by Predeep and Manavalan. The modification consists to use a high scale quantization, which is 20 in order to realize a heavy quantization for the DCT to achieve a high compression. A comparative study is performed to show the contribution of this modification.
CRISPR/Cas9-Mediated Targeted DNA Integration: Rearrangements at the Junction of Plant and Plasmid DNA

Targeted DNA integration into known locations in the genome has potential advantages over the random insertional events typically achieved using conventional means of genetic modification. We studied the presence and extent of DNA rearrangements at the junction of plant and transgenic DNA in five lines of Arabidopsis thaliana suspension cells carrying a site-specific integration of target genes. Two types of templates were used to obtain knock-ins, differing in the presence or absence of flanking DNA homologous to the target site in the genome. For the targeted insertion, we selected the region of the histone H3.3 gene with a very high constitutive level of expression. Our studies showed that all five obtained knock-in cell lines have rearrangements at the borders of the integrated sequence. Significant rearrangements, about 100 or more bp from the side of the right flank, were found in all five plant lines. Reorganizations from the left flank at more than 17 bp were found in three out of five lines. The fact that rearrangements were detected for both variants of the knock-in template (with and without flanks) indicates that the presence of flanks does not affect the occurrence of mutations.
Ethylene Production by ‘Valencia’ Peel Explants Treated with Abscission-accelerating Compounds1

Ethylene production in peel explants of ‘Valencia’ oranges [Citrus sinensis (L.) Osbeck] treated with 5-chloro-3-methyl-4-nitro-1H-pyrazole (Release) was similar in pattern to ethylene production by whole fruits treated with the chemical. Smaller amounts of ethylene were produced by untreated peel explants. Explants from fruit harvested in October and March showed similar patterns of ethylene evolution when untreated and when Release was applied. The response to this chemical was localized in the flavedo. Ethylene production was dependent on temperature in both untreated and Release-treated peel explants, but the ethylene response to the chemical was particularly temperature-dependent. The temperature optimum in both cases was approximately 25°C. Peel disks from regreening fruit generally produced less ethylene than disks from nongreening fruit when Release or glyoxal dioxime (ethanedial dioxime, Pik-Off) was applied. The magnitude of the difference between regreening and nonregreening disks depended on the concentrations of Pik-Off or Release applied.

Genome-Wide Survey and Expression Analyses of Hexokinase Family in Poplar (Populus trichocarpa)

Hexokinase (HXK) family proteins exert critical roles in catalyzing hexose phosphorylation, sugar sensing, and modulation of plant growth and stress adaptation. Nevertheless, a large amount remains unknown about the molecular profile of HXK enzymes in Populus trichocarpa, a woody model tree species. A genome-wide survey of HXK-encoding genes, including phylogenies, genomic structures, exon/intron organization, chromosomal distribution, and conserved features, was conducted, identifying six putative HXK isogenes (PtHXK1-6) in the Populus genome. The evolutionary tree demonstrated that 135 homologous HXKs between 17 plant species were categorized into four major subfamilies (type A, B, C, and D), clustering one plastidic (PtHXK3) and five mitochondrial PtHXKs grouped into type A and B, respectively. The in silico deduction prompted the presence of the conserved sugar-binding core (motif 4), phosphorylation sites (motif 2 and 3), and adenosine-binding domains (motif 7). The transcriptomic sequencing (RNA-seq) and the quantitative real-time PCR (qRT-PCR) assays revealed that three isogenes (PtHXK2, 3, and 6) were abundantly expressed in leaves, stems, and roots, while others appeared to be dominantly expressed in the reproductive tissues. Under the stress exposure, PtHXK2 and 6 displayed a significant induction upon the pathogenic fungi (Fusarium solani) infection and marked promotions by glucose feeding in roots. In contrast, the PtHXK3 and 6 are ABA-responsive genes, following a dose-dependent manner. The comprehensive analyses of the genomic patterns and expression profiling provide theoretical clues and lay a foundation for unraveling the physiological and signaling roles underlying the fine-tuned PtHXKs responding to diverse stressors.
Early Dental Implant Failure in Patient with Active Implant Periapical Lesions: Lesson Learnt from Two Case Reports

Implant periapical lesion (IPL) is also known as retrograde peri-implantitis and as the name suggests, it involves inflammation surrounding the apical part of the dental implants. Previously, many studies have reported the event of IPL that further delays osseointegration, and some reported failure of implant placement due to this disease. In this article, we described two cases of early dental implant failure that was associated with active IPL and correlated the clinical and radiographical findings with the histopathological findings.
Comparison of TLS and Photogrammetric 3D Data Acquisition Techniques: Considerations for Developing Countries

– With the use of digital data, in conjunction with technologies such as BIM and digital twin, construction professionals have the ability to monitor the progress efficiently and perform detailed quality assessments. The rapid development of multiple data acquisition technologies, such as terrestrial laser scanning (TLS) and photogrammetry techniques, has allowed their broad integration in mostly middle to large-scale construction projects worldwide. However, this type of technology is often not accessible to small-scale contractors, especially in developing countries where high upfront costs and lack of skilled workers might be limiting factors. This study compares the economic, quality, feasibility, and value of TLS versus Photogrammetric data acquisition methods; i.e., the scope is not to discuss the benefits of using 3D digitization techniques but to consider if small-scale contractors can still take advantage of said benefits by using affordable technologies. Moreover, the impact of achieving complete automation by employing robotic platforms with TLS systems is also considered. A small case study is used to illustrate the quality and economic comparisons.

Earnings Management: An Analysis of Corporate Strategy, Financial Performance, and Audit Quality

This study aims to examine the effect of corporate strategy on earnings management with financial performance and audit quality as moderating variables. This study adopts the concept proposed by Miles and Snow in determining company strategy. The proxies for business strategy are the number of employees to total sales (EMPSAL), the capital expenditure ratio to total assets (CAPTA), and the dividend payout ratio (DPR). Financial performance is proxied by return on assets (ROA), auditor size measures audit quality, and discretionary accruals measure earnings management. The sample was determined using a purposive sampling method, and a sample of 16 companies was obtained with 80 observations. Companies grouped by prospector and defender strategies were analyzed using cluster analysis. Data analysis was carried out using moderated regression analysis (MRA). The results shows that a company's strategy affects earnings management, and that firm performance and auditor quality can moderate the relationship between corporate strategy and earnings management.
Coherencia textual: ¿coherencia interna o coherencia externa?

This article shows how the different treatments of phenomenon of the textual coherence have taken two fundamental directions: a) to try to explain the coherence by one internal principle of the text, b) or to try it by one external principle. It will be argued in this paper that only from the text itself (internal coherence) could offer one satisfactory answer to such question. Meanwile, it demonstrates how external factors colaborate to the establishment of the textual coherence.
Architectural Survey, Diagnostic, and Constructive Analysis Strategies for Monumental Preservation of Cultural Heritage and Sustainable Management of Tourism

Heritage is under constant pressure to be adapted for tourism. The aim of this research was to improve the performance of both the tourism sector and the cultural heritage sector in a balanced and sustainable way, by considering the principles of conservation and preservation. Non-invasive tools such as ground penetrating radar (GPR), unmanned aerial vehicle (UAV), and even virtual reality (VR) and augmented reality (AR) technologies have been used to develop new methodologies, allowing us to generate new experiences and heritage tourist attractions, which not only do not generate negative impacts on the monuments themselves, but also promote their preservation without diminishing the cultural and tourist offers of the city. A case study was carried out on Mérida, a UNESCO World Heritage City, where tourism is a strong economic engine of the city. The results obtained are two-fold: on one hand, an effective interdisciplinary working methodology for heritage management was developed, and on the other hand, new approaches for the sustainable development of cultural tourism were generated.
Electrochemical hydrogen storage: Achievements, emerging trends, and perspectives

Hydrogen being abundant, eco‐friendly, is a promising alternative energy source to fossil fuels. Its practical application is limited because of difficulty in storage due to low energy density and safety issues. Solid‐state electrochemical hydrogen storage is a promising method among several approaches of hydrogen storage to meet the U.S. Department of Energy's (DOE) targets. Till 2020, no hydrogen storage material has achieved targets due to lack of proper strategies. In view of meeting targets decided by U.S. DOE, a detailed review of whole progress made in electrochemical hydrogen storage approaches and materials is presented. The reported hydrogen storage capacities of Graphene (1.21 wt.%), reduced Graphene Oxide (2.7 wt.%), Mg‐based alloys (up to 7.6 wt.%), hydrogen clathrates (up to 4.2 wt.%), Pervoskite oxides (up to 4 wt.%), and Nd2Sn2O7 (up to 14.86 wt.%) are consolidated at one place and disclosed. The shortcomings hindering current hydrogen storage technologies are summarized and the scope of future improvement in hydrogen storage is outlined. Emerging materials and technologies are mentioned which can progress towards achieving U.S. DOE targets. This review can assist researchers in choosing an appropriate strategy or potential material for electrochemical hydrogen storage.
The North Italian Longitudinal Study Assessing the Mental Health Effects of SARS-CoV-2 Pandemic on Health Care Workers—Part I: Study Design and Psychometric Structural Validity of the HSE Indicator Tool and Work Satisfaction Scale

Literature on the impact of the SARS-CoV-2 pandemic on the mental health of Health Care Workers (HCWs) is mostly based on cross-sectional surveys. We designed a longitudinal study to assess work-related stress and mental health before and after the pandemic onset in a university-hospital in Lombardia region, Italy. We report on sample representativeness and structural validity of questionnaires assessing work stress (HSE Indicator Tool, HSE-IT) and work satisfaction (WS), which were not validated in the HCWs population. n = 1287 HCWs from 67 hospital wards/offices were invited to an online survey in summer 2019 (pre-COVID-19 wave) and again during winter 2020 (COVID-19 wave). Selected hospital wards/offices did not differ from the remaining wards for turn-over and down-sizing rates, overload, sick leaves, and night shifts (Wilcoxon rank tests p-values > 0.05). Participation rates were 70% (n = 805) and 60% (n = 431) in the pre-COVID-19 and COVID-19 waves, respectively. Socio-demographic and work-related characteristics did not impact data completeness nor participation to the COVID-19 wave. While confirming a 7-component structure for HSE-IT, we identified a new factor related to participation in work organization. A one-factor model for WS had satisfactory fit. Our longitudinal study based on a representative sample and adopting validated questionnaires is well-suited to elucidate the role of work conditions on the development of mental health disorders in HCWs.
Raw Chicory Roots Powder has Impact on Various Biomarkers of Colorectal Cancer in Male Wistar Rats

Prebiotics modulate metabolism and ensure a healthy gastrointestinal tract that may prevent colorectal cancer (CRC) development. The present study was designed to explore the effects of chicory roots derived fructans, in raw form, against CRC in rats. After acclimatization period, forty male Wistar rats were randomly and equally divided into four groups. Chicory powder treatments were started to group G4 before administering carcinogenic injections. After one-month, groups G2-G4 received four subcutaneous injections of carcinogen 1,2-dimethylhydrazine dihydrochloride (DMH) at dose of 40 mg/kg body weight, twice a week for 2 weeks. After DHM injections, chicory powder treatments were started to group G3 as well and group G2 was DHM control group receiving only basal diet while G1 was normal control group. The amount of chicory roots powder given was 5% w/w mixed in basal diet. It was observed that group G4 showed better results overall. Enzymatic activities of pathogenic bacteria were lowest in this group and were significant (p≤0.05) when compared to group G2. Percentage of total aberrant crypt foci (ACF) inhibition was also higher (30.14%) in group G4 as compared to group G3 (18.55%). Elevated levels of short chain fatty acids were observed in chicory root powder groups particularly in G4 which having significant higher levels of acetate and butyrate compared to group G2. Group G4 also hindered body weight loss due to carcinogenesis effect. It can be concluded that chicory root powder has protective impact against CRC biomarkers particularly if it is taken as preventive measure.
Convex radiant costarshaped sets and the least sublinear gauge

The paper studies convex radiant sets (i.e. containing the origin) of a linear normed space X and their representation by means of a gauge. By gauge of a convex radiant set C c X we mean a sublinear function p : X ==> R such that C = [p 0 : x e lC}, the set C may have other gauges, which are necessarily lower than mC. We characterize the class of convex radiant sets which admit a gauge different from mC in two different way: they are contained in a translate of their recession cone or, equivalently, they are costarshaped, that is complement of a starshaped set. We prove that the family of all sublinear gauges of a convex radiant set admits a least element and characterize its support set in terms of polar sets. The key concept for this study is the outer kernel of C, that is the kernel (in the sense of Starshaped Analysis) of the complement of C. We also devote some attention to the relation between costarshaped and hyperbolic convex sets.
The Use of Boston Dynamics SPOT in Support of LiDAR Scanning on Active Construction Sites

– With the recent commercial availability of autonomous mobility platforms, construction researchers have focused their attention to the application of advanced robotic tools on jobsites. One such mobility platform is Boston Dynamic’s robot, “SPOT. ” The software development kit (SDK) enabled, quadruped robot has the infrastructure to attach interchangeable payloads including LiDAR (Light Detection And Ranging) scanners. Researchers have conducted a pilot study comparatively analyzing terrestrial LiDAR scans from a human-based tripod scan system and the scans executed by SPOT in both manual and autonomous modes. The research looked at three metrics – quality of scans, productivity savings, and robot accuracy. The result shows that although scan quality is slightly diminished due to the height and shape of the robot, the productivity gains from an autonomous robot could offset the scan quality with additional scans. In addition, in small sample testing, the robot was accurate in returning to a pre-defined location in autonomous mode. Due to the page limit, this paper only presents the results and findings of quality of scans of this this research study.
Transfer of "good" and "bad" functions within stimulus equivalence classes.

This study compared results of two experiments that tested transfer of function in stimulus equivalence classes in a task dissimilar to (in Experiment I) and similar to (in Experiment II) the task that trained functional responding. Eleven students from UNT participated in return for monetary compensation. Phase 1 and 2 were identical in the two experiments, in which they established stimulus equivalence classes and functional responding, respectively. Each experiment then used different tasks in the third phase to test differential responding. Only participants in Experiment II demonstrated consistent transfer of function. Results are discussed in terms of how task similarity may function as a type of contextual control when there is limited experience with the task.
Evaluation of the Binding Relationship of the RdRp Enzyme to Novel Thiazole/Acid Hydrazone Hybrids Obtainable through Green Synthetic Procedure

The viral RNA-dependent RNA polymerase (RdRp) complex is used by SARS-CoV-2 for genome replication and transcription, making RdRp an interesting target for developing the antiviral treatment. Hence the current work is concerned with the green synthesis, characterization and docking study with the RdRp enzyme of the series of novel and diverse hydrazones and pyrazoles. 4-Methyl-2-(2-(1-phenylethylidene)hydrazineyl)thiazole-5-carbohydrazide was prepared and then condensed with different carbonyl compounds (aldehydes and ketones either carbocyclic aromatic or heterocyclic) afforded the corresponding hydrazide-hydrazones. The combination of the acid hydrazide with bifunctional reagents such as acetylacetone, β-ketoesters (ethyl acetoacetate and ethyl benzoylacetate) resulted in the formation of pyrazole derivatives. The synthesized compounds were all obtained through grinding method using drops of AcOH. Various analytical and spectral analyses were used to determine the structures of the prepared compounds. Molecular Operating Environment (MOE®) version 2014.09 was used to estimate interactions between the prepared thiazole/hydrazone hybrids and RdRp obtained from the protein data bank (PDB: 7bv2) using enzyme-ligand docking for all synthesized derivatives and Remdesivir as a reference. Docking results with the RdRp enzyme revealed that the majority of the investigated drugs bind well to the enzyme via various types of interactions in comparison with the reference drug.
