Infrared Spectroscopy of Neutral and Cationic Benzonitrile–Methanol Binary Clusters in Supersonic Jets
Authors: Xiong Xianming , Hu Yongjun
Published: June 2024

The formation of nitrogen-containing organic interstellar molecules is of great importance to reveal chemical processes and the origin of life on Earth. Benzonitrile (BN) is one of the simplest nitrogen-containing aromatic molecules in the interstellar medium (ISM) that has been detected in recent years. Methanol (CH3OH) exists widely in interstellar space with high reactivity. Herein, we measured the infrared (IR) spectra of neutral and cationic BN–CH3OH clusters by vacuum ultraviolet (VUV) photoionization combined with time-of-flight mass spectrometry. Combining IR spectra with the density functional theory calculations, we reveal that the BN–CH3OH intends to form a cyclic H-bonded structure in neutral clusters. However, after the ionization of BN–CH3OH clusters, proton-shared N···H···O and N···H···C structures are confirmed to form between BN and CH3OH, with the minor coexistence of H-bond and O-π structures. The formation of the proton-shared structure expands our knowledge of the evolution of the life-related nitrogen-containing molecules in the universe and provides a possible pathway to the further study of biorelevant aromatic organic macromolecules.

Published: June 2024

E. coli is an important zoonotic pathogen capable of causing foodborne illness and bovine mastitis. Bacteriophages have been increasingly considered a promising tool to control unwanted bacteria. The aim of this study is to determine the antibiotic resistance profile of E. coli isolated from raw milk and the efficacy of phage in controlling multidrug-resistant E. coli in raw milk. Antibiotic susceptibility testing showed the highest resistance rates of E. coli isolates to co-trime (27.34%) and ampicillin (27.34%), followed by streptomycin (25.18%), tetracycline (23.02%), and the lowest resistance rates to ciprofloxacin, gentamycin, and ceftazidime, all at a rate of 2.16%. All isolates were susceptible to meropenem. Of the 139 E. coli isolates, 57 (41.01%) were resistant to at least one antibiotic, and 35 (25.18%) were classified as MDR strains. Molecular characterization indicated that 5 (3.6%) out of the 139 isolates were STEC strains carrying stx1 gene. Seven (5.04%) isolates were phenotypically identified as ESBLEC, and four isolates (2.88%) were resistant to colistin. The results of the genotypic test revealed that four out of seven ESBLEC strains carried both blaTEM and blaCTX-M-1, two harbored blaTEM, and one possessed blaCTX-M-1, while mcr-1 was detected in all four colistin-resistant E. coli isolates. In particular, one isolated E. coli strain (EM148) was determined to be a multidrug-resistant strain simultaneously carrying blaTEM, blaCTX-M-1, and mcr-1. A total of eight phages were successfully recovered from raw milk. The application of phage PEM3 significantly reduced viable counts of multidrug-resistant host EM148 in raw milk by at least 2.31 log CFU/mL at both 24 °C and 4 °C.

Published: June 2024

To promote the application of economical and sustainable polyphosphoric acid (PPA)-modified asphalt in road engineering, styrene-butadiene block copolymer (SBS), styrene-butadiene rubber (SBR), and PPA were used to prepare PPA/SBS and PPA/SBR composite-modified asphalts, which were tested and the data analyzed. Fourier transform infrared spectroscopy (FTIR) tests and thermogravimetric analysis (TG) tests were carried out to study the modification mechanisms of the composite-modified asphalts, and the high-temperature performance of the PPA-modified asphalt and asphalt mixtures was analyzed by dynamic shear rheology (DSR) tests and wheel tracking tests. A gray correlation analysis and a back-propagation (BP) neural network were utilized to construct a prediction model of the high-temperature performance of the asphalt and asphalt mixtures. The test results indicate that PPA chemically interacts with the base asphalt and physically integrates with SBS and SBR. The PPA-modified asphalt has a higher decomposition temperature than the base asphalt, indicating superior thermal stability. As the PPA dosage increases, the G*/sinδ value of the PPA-modified asphalt also increases. In particular, when 0.6% PPA is combined with 2% SBS/SBR, it surpasses the high-temperature performance achieved with 4% SBS/SBR, suggesting that PPA may be a good alternative for polymer modifiers. In addition, the creep recovery of PPA-modified asphalt is influenced by the stress level, and as the stress increases, the R-value decreases, resulting in reduced elastic deformation. Furthermore, the BP neural network model achieved a fit of 0.991 in predicting dynamic stability, with a mean percentage of relative error (MAPE) of 6.15% between measured and predicted values. This underscores the feasibility of using BP neural networks in predictive dynamic stability models.

Le contexte socio-économique du catharisme au Mas-Saintes-Puelles dans la première moitié du 13e siècle
Authors: Šemkov Georgi
Published: June 2024

Zu welchen gesellschaftlichen Schichten gehörten die Katharer, sowohl die gewöhnlichen Gläubigen ("credentes") als auch die Vollendeten ("perfecti"), im südfranzösischen Ort Mas-Saintes-Puelles und warum wurden sie Ketzer? Auf diese Fragen versucht der vorliegende Aufsatz, anhand des Ms. 609 (Bibliothèque Municipale de Toulouse) eine Antwort zu geben. Fast die ganze Adelsfamilie, ein großer Teil der vornehmen Einwohner, das aufkommende Bürgertum, die meisten Handwerker, ein Priester und da es sich um eine ländliche Siedlung handelt, ebenfalls eine große Gruppe bedauerlicherweise in sozialer Hinsicht anonym gebliebener Bauern gehörten zum Anhang der Häresie. Der Klassenkampf konnte also nicht das Motiv der Bewohner von Mas-Saintes-Puelles sein, um sich dem Katharismus anzuschließen. Im übrigen ist es aufgrund der Inquisitionsdokumente schwierig zu erraten, aus welchen Beweggründen die Katharer in dieser Siedlung gehandelt haben. Mancher Fall äußerster Selbstaufopferung auf dem Scheiterhaufen zeigt ihren Glaubensidealismus.

Published: June 2024

The present study evaluated the effect of active coverings based on gum arabic incorporated with protein hydrolysates and/or citric acid on the characteristics of fried potato (Solanum tuberosum L.) chips. After the minimum processing and whitening, different coatings were applied to the potatoes: control (without coating); 5% (w/v) gum arabic and 2% (w/v) protein hydrolysate with 10% degree of hydrolysis (DH); 5% (w/v) gum arabic and 2% (w/v) protein hydrolysate with 20% DH; 5% (w/v) gum arabic and 2% (w/v) citric acid. Afterwards, the chips were vacuum-packed and stored at 4 °C. The different treatments were evaluated at time zero, 3, 5, 7 and 10 days of storage: in natura for total aerobic mesophiles, moulds and yeasts, and thermotolerant coliforms; and characterised for colour (L*, a*, b*), texture, moisture and lipids after frying at 180 °C for 5 min. The evaluated samples did not present thermotolerant coliforms (<0.03 MPN/g). Furthermore, the use of citric acid inhibited moulds and yeasts and delayed the multiplication of total aerobic mesophiles. Luminosity (L*) was significantly reduced in the control treatment. Treatments with 5% (w/v) gum arabic and 2% (w/v) protein hydrolysate (10% and 20% DH, respectively) showed greater redness (a*) and blueness (b*) relative to the control. Applying protein hydrolysate-containing coatings to French fries led to lowered firmness, and reduced moisture and lipid contents at the end of storage. Thus, the coatings with added protein hydrolysates show a promising application in producing fried potato chips with reduced oil content.

Background and aims: The COVID-19 pandemic emerged in late 2019 with increased infection and mortality rates. Even with observing safety measures, medical staff have to deal with a high level of mental and physical pressure during an epidemic, and they might demonstrate diverse behaviors rooted in their experiences and emotions toward the situation. The paper examines different experiences and emotions of medical staff dealing with COVID-19 in Ilam, Iran. Methods: A cross-sectional study was carried out with the participation of 200 care providers in 2020. Data was gathered using two questionnaires: the scale of positive and negative emotions (SPANE) and the positive and negative affect scale (PANAS). Data analyses were done in STATA12 using linear regression models. Results: The mean score of positive emotion in ICU, general, maternity, and administrative wards in women were 32±6.23, 34.07±6.74, 35.35±9.24, and 35.61±6.91 respectively. The mean scores of Negative emotions in the Maternity ward and administrative departments were higher than in the ICU and CCU wards (P=0.05). The midwives’ mean negative emotions score was lower than the physician’s (P value<0.05). Average levels increased by about 4.41 scores in negative experiences for individuals with a work experience higher than 25 years compared to those with work experience less than ten years (P=0.03). Conclusion: Factors such as type of work, workplace, and work experience that affect care providers’ positive and negative experiences and emotions should be considered in staffing arrangements and their expectations.

Published: June 2024

The project focused on the design, construction, and testing of a working model of an RC controlled stealth aircraft. A multidisciplinary approach was adopted, incorporating aerodynamics, electronics, materials, and control systems to achieve the desired performance. The aerodynamic design of the model involved careful consideration of the shape, contours, andsurfaces. The goal was to minimize radar reflections and reduce the infrared signature, leading to the incorporation of smooth and streamlined surfaces, blended wing profiles, and carefully shaped edges.RC channel mixing was implemented to coordinate the movements of control surfaces. This allowed for synchronized actions of ailerons, elevators, rudder, and flaps, facilitating precise maneuvering and stability during flight. By combining input signals from multiple control channels, the model's control surfaces operated seamlessly, emulating the behavior of larger stealth aircraft. The construction process focused on assembling a lightweight yet sturdy airframe using appropriate materials. Structural integrity was ensured to withstand the aerodynamic forces encountered during flight. Extensive testing and fine-tuning were conducted to optimize the model's performance, including stability, responsiveness, and stealth characteristics. The completion of the project resulted in a fully functional RC controlled stealth aircraft model.

Authors: A. Rakeshwar  , A. Saravanakumar  , K. Senthilkumar
Published: June 2024

The field of acoustics is emerging as a significant supplementary modality that should be investigated and utilized in the development of intelligence and surveillance systems. These systems often depend on technology that is rooted in the singularity of electromagnetic fields. Acoustic sensors are preferred because of their affordability, robustness, and small size. They are also passive. Furthermore, sound energy can go beyond a line of sight. The current scenario can be used to the detection and localization of sound sources utilizing Unmanned Aerial Vehicle (UAV) and ground-based Acoustic Sensors. An acoustic sensor placed on the ground detected the target's immediate frequency.An Acoustic Sensor above the ground generates Doppler altered frequency time records to determine flight characteristics. The Acoustical Doppler Effect causes the instantaneous frequency perceived to fluctuate on a straight-line trajectory with constant velocity.The Nelder-Mead technique is used to estimate the low flying UAV's motion characteristics based on the instantaneous frequency model.
