Green synthesis of silver nanoparticles using durian rind extract and optical characteristics of surface plasmon resonance-based optical sensor for the detection of hydrogen peroxide
Authors: Chutrakulwong Fueangfakan , Thamaphat Kheamrutai 
Published: August 2023

Abstract
Silver nanoparticles (AgNPs) have been efficaciously synthesized from AgNO3
via an easy and green method, also called green synthesis, using Mon Thong durian (Durio zibethinus L.) rind extract. The inner shell of durian rind extract was used as an intermediary for the synthesis of AgNPs because the absorption spectra of the AgNP colloid extracted from the inner shell had a higher absorption than that of the outer shell. Additionally, we have found more fructose and glucose – which act as a reducing agent – and protein and carbohydrates – which act as the stabilizer – in a higher amount in the inner shell than the extract from the outer shell. The synthesized AgNPs were mainly spherical in shape and exhibited a relatively narrow size distribution with an average particle diameter of 10.2 ± 0.2 nm. In the reduction of hydrogen peroxide (H2O2), these nanoparticles demonstrate catalytic activity. The degradation of AgNPs, including the catalytic decomposition of H2O2, causes a considerable change in the absorbance strength of the surface plasmon resonance band depending on the H2O2 concentration. Over a broad concentration range of 10−1–10−6 mol·L−1 H2O2, a good sensitivity and a linear response are achieved. This sensor’s quantification limit is found to be 0.9 µmol·L−1 H2O2. Therefore, this optical sensor for the detection of H2O2 can be potentially applied in the determination of color indicators in medical or clinical diagnosis, biochemical analysis, and environmental applications.

Abstract
Steels with different mechanical and chemical properties are used together in the oil and gas industry. In this case, it has brought about the necessity of joining steels with different properties by welding. Most of the time, there are problems in welding these steels with different chemical properties. Therefore, in this study, AISI 304 stainless steel, AISI 4140 tempered steel, and S235JR structural steel with different chemical and mechanical properties used in the oil and gas industry were joined by friction welding. Then, macro and microstructure studies as well as hardness measurements, tensile tests, and torsion tests were applied to the produced samples. As a result of the micro-structure studies, it was observed that the martensitic structure was formed in the full deformation region of the joint made of AISI 304 stainless and AISI 4140 tempered steel, while it was determined that the other joints were formed of recrystallized fine grains in the full deformation region with the effect of friction. When the hardness measurement results were examined, it was determined that the hardest region was the full deformation region in all welded joints produced. As a result of the tensile tests, the highest tensile strength obtained was 622.94 N/mm2 in the joint made of AISI 304 stainless steel and AISI 4140 tempered steel. As a result of the torsion tests, the highest torsion moment was measured as 250 Nm in the sample produced from AISI 304 stainless steel and AISI 4140 tempered steel.

Abstract
A research project aiming to determine the functional aspects of flint-knapping of the Lublin-Volhynian culture (ca. 4200–3650/3600 BC) has been conducted for several years in the Institute of Archaeology at the Maria Curie-Skłodowska University in Lublin.
This article presents deliberations on the functions of tools discovered in a rich male grave, at site 1C in Gródek. The subject of the functional research are nine artefacts deposited near the buried person. Among them, noteworthy are two retouched blade daggers found on the buried man’s rib cage. Other items – blades and tools – were discovered in different parts of the burial pit. When conducting microscopic analyses, attention was paid to the fact that the discovered forms represent two categories – used artefacts and those that do not have marks of utilisation on their edges.
Spectrometric analyses (SEM-EDS) of residual substances recorded on the surfaces of certain artefacts supplemented the performed research.

Published: August 2023

Introduction:
Although most COVID-19 infections are currently mild, poor prognoses and fatalities continue to occur, which remain a threat to the safety of people in China. The goal of this study was to create an efficient model that combines the clinical characteristics with computed tomography (CT) scores at the time of admission to predict the severity of COVID-19.

Methodology:
A total of 346 COVID-19 patients in the current study, of whom 46 had severe infections and 300 had non-severe infections according to the clinal outcomes. Clinical, laboratory, CT findings, and CT scores at admission were collected. To identify the independent risk factors, univariable and multivariable logistic regression analyses were performed. A nomogram model was built with the extracted risk factors. The calibration curve and decision curve (DCA) operated to validate model performance.

Results:
The receiver operating characteristic curve indicated that the severity CT score had an area under the curve of 0.933 (95% CI, 0.901-0.965) and a cut-off value of 6.5 (sensitivity, 95.70%; specificity, 78%). The CT score, age, lactic dehydrogenase and hydroxybutyrate dehydrogenase levels, and hypertension were exacted for the nomogram. The nomogram had good calibration (P = 0.539) and excellent clinical value based on the DCA.

Conclusions:
The nomogram presented herein could be a valuable model to predict severe COVID-19 among patients in Chengdu, China.

Published: August 2023

Prepositions are unique closed-class grammatical forms that have syntactic and semantic qualities. They act as vital markers to the structure of a sentence and reveal the spatial, temporal, or logical relationship of their object to another part of the sentence. This study investigates the difficulties that BA students face when translating prepositions. The sample consisted of 60 students from three private universities. To achieve the objectives a translation Cloze Test consisting of 30-statements was used. The data resulting was concluded using the Level of Achievement Score. The results showed that students fail to recognize prepositions as parts of multiword expressions. Understanding prepositions involve understanding their interpersonal, textual, and ideational meaning, which requires understanding their semantic and syntactic role. There are many differences between prepositions in the way they are conceptualized in each language. It also revealed that communicative translation is one of the most successful techniques in translation.
Fault Rheology Control on Rupture Propagation and Aftershocks Distribution during the 2016–2017 Central Italy Earthquakes

Published: August 2023

Abstract
The stress released by the large coseismic ruptures and related aftershock sequences is strongly a heterogeneous process. We show highly resolved images of the normal fault system ruptured during the 2016–2017 central Italy earthquake sequence, as obtained by the high-resolution local earthquake tomography allowing relocation of a massive set of aftershocks. We get evidence that lateral changes of elastic properties on the fault planes account for the complexity in the rupture processes during the two Mw &gt; 6 earthquakes. We observe an emergent phase in the first part of the Mw 6.5 rupture, and the coseismic slip becomes large when the rupture breaks through high Poisson ratio portions of the fault. Mainshocks break the fault portions that, although limited and segmented by inherited structural complexity, were dynamically interfering during the faulting episodes. The close repetition of slip on the same relatively high Poisson ratio patch suggests a dynamic weakening of the fault and/or an incomplete stress release during the first mainshock.

The increasing aging population worldwide is one of the main issues of today. According to the 2011 census, there were 103 million senior citizen i.e about 8.6% of the India’s population. According to data from the U. N Department of Economic and Social Affairs (UNDESA), the proportion of people over 60 will increase from 7.5% in 2010 to 11.1% in 2025. The NSSO 2002 report, the old population is expected to increase to 158.7 million by 2025, rising at a rate that is roughly twice as fast as the general population associated with Perceived Dysphagia, Cognition and Health-Related Quality of Life in Geriatrics populations.Dysphagia is becomes an important common problem for the geriatric population. While Presbyphagia is a term that refers to the distinctive age-related changes that occur in the swallowing mechanism of otherwise healthy older adults. It is well defined that in acutely ill elderly populations, the prevalence and quality-of-life changes associated with dysphagia remain unstable poor health conditions. The present study attempt “To investigate an Inquisitive Exploration on Perceived Dysphagia, Cognition and Health-Related Quality of Life in Geriatrics”.A total of 300 participants were included in the study. The participants within the study were all inhabitants of Pondicherry. The individual with geriatric inclusion was 70 years old and above at the time of participation. Two validated questionnaires were used namely the M.D. Anderson Dysphagia Inventory (MDADI) and the general health Short Form-12 survey (SF-12v2) was administered to assess the impact of dysphagia-age related aspects on overall health. Both the questionnaires were self-administered and widely used in assessing cognitive function among the elderly, it includes orientation, attention, memory, language, and visuospatial skills.The study outcome concluded that there is a relatively high prevalence of dysphagia in the community-based geriatric population; significant quality-of-life impairment is a frequent finding. General health measures do not appear to be sensitive to swallowing-related quality of life but finally, individuals may inaccurately ascribe swallowing problems to normal aging, supporting the role of community education about dysphagia in the elderly.

Published: August 2023

Drought is an important factor seriously affects agricultural production worldwide. Agricultural practices that can increase resistance to drought are gaining importance. In this study the role of nano-silicon dioxide (NaSiO2) in countering drought stress in invitro strawberry plantlets were investigated. In the experiment, the effects of PEG 6000 concentrations (0, 4, 8%) and NaSiO2 concentrations (0, 50, 100 mg L-1) on invitro strawberry plants were determined. Plantlets treated with PEG 6000 showed reduced vegetative growth parameters, but this decrease was reduced with NaSiO2 application. NaSiO2 at 50 mg L−1 induced the maximum shoot and root fresh weight (1.20 g, 1.24 g, respectively) and length (40.09 mm, 34.26 mm, respectively), leaves number (16.67 pieces/plant) and SPAD index 53.57 among 4% and 8% PEG applications. When the SOD and CAT activities were examined, the results showed that application of NaSiO2 enhancement drought stress tolerance by promoted certain antioxidant response by increasing SOD and catalase (CAT) activities under drought stress. According to the results NaSiO2, limited the devastating impact of drought stress and markedly enhanced all the examined parameters.

Published: August 2023

Urothelial cell carcinoma (UCC, bladder cancer) remains a difficult to treat malignancy with rising incidence worldwide. In the U.S., UCC is the sixth most incident neoplasm and ~90% of diagnoses are made in those &amp;gt;55 years of age, ~four times more commonly observed in men than women. The most important risk factor for developing bladder cancer is tobacco smoking, which accounts for ∼50% of cases followed by occupational exposure to aromatic amines and ionizing radiation. The standard of care for advanced UCC includes platinum-based chemotherapy and programmed cell death (PD-1) or programmed cell death ligand 1 (PD-L1) inhibitors, administered as frontline, second-line, or maintenance therapy. UCC is highly aggressive and remains generally incurable since these cancers are associated with intrinsic and acquired drug resistance. UCC is highly lethal in the metastatic state and characterized by genomic instability, high PD-L1 expression, DNA damage-response mutations, and high tumor mutational burden. Although immune checkpoint inhibitors (ICIs) achieve long-term durable responses in other cancers, their ability to achieve similar results with metastatic UCC (mUCC) is not as well-defined. Here, we discuss the novel therapies to improve the management of mUCC.

Published: August 2023

In this paper we present methodology for precise calibration of Molecular Beam Epitaxy (MBE) growth process and achieving run to run stability of growth parameters. We present the analysis of the influence of fluxes stability during the growth of long wavelength quantum cascade laser structures designed for the range λ ~ 12–16 µm on wavelength accuracy with respect to desired emission wavelength. The active region of the lasers has a complex structure of nanometer thickness InxGa1-xAs/InyAl1-yAs superlattice. As a consequence, the compositional and thickness control of the structure via bulk growth parameters is rather difficult. To deal with this problem we employ methodology based on double-superlattice test structures, that precede the growth of the actual structures. The test structures are analyzed by high-resolution X-ray diffraction which allows to calibrate the growth of the complex active region of quantum cascade laser structures. We also study theoretically the effect of individual flux changes on emission wavelength and gain parameters of the laser. The results of simulations allow for determination of flux stability tolerance, preserving acceptable parameters of the laser and provide means of emission wavelength control. The proposed methodology was verified by the growth of laser structures for emission at around 13.5 μm.
