Authors: Pajón-Julio A. , Campos-Coy M.A. , Villarreal-Del-Bosque N.
Published: July 2024

The head and neck region has a complex anatomy, making assessing lesion extension challenging. Current CT technology has not been able to overcome these challenges. Both static and dynamic maneuvers have been developed to better evaluate some areas where mucosal apposition prevents
appropriate lesion characterization. Static maneuvers do not require modification of the breathing pattern and can be performed during quiet breathing acquisition. Dynamic maneuvers require an extra acquisition, with increased radiation exposure; thus, patients and scanning areas should be
carefully selected. The purpose of this article is to describe these maneuvers, how to perform them, and their clinical application.Learning Objective: To describe useful dynamic and static maneuvers in head and neck diagnostic imaging and recognize the structures that may be better assessed
by performing them

Authors: Rodrigues Priyanka , Chaudhary Sunetra
Published: July 2024

Quantitative extraction of the Pd(II) complex with 5-Chlorosalicylaldehyde thiosemicarbazone (CSTSC) was achieved at pH levels ranging from 3.6 to 4.4 after a 30-second equilibration period in n-butyl acetate. When the concentration of Pd(II) does not exceed 9.0 μg mL-1, the complex formed between Pd(II) and 5-Chlorosalicylaldehyde thiosemicarbazone complies with Beer's law, and it displays the highest absorbance at 400 nm. By means of the mole ratio method and the Jobs continuous variation method, it was determined that the stoichiometry of the Pd(II)-CSTSC complex is 1:2. The stability of the extracted complex persisted for 96 hours. The calculated Sandell's sensitivity was 9.92 x 10-3 μg cm-2, while the molar absorptivity was found to be 1.072 x 104 L mol-1 cm-1. Utilizing this method, effective analysis has been carried out on synthetic samples, complexes, and water samples.

Microwave radiation of space and prospects for its use in quantum propulsors
Authors: Avakyan S. V. , Baranova L. A. , Kovalenok V. V. , Savinykh V. P.
Published: July 2024

Using the original approach developed in recent years – supramolecular physics of the environment, the results of considering the contribution of physical optics processes to the formation of induced microwave radiation are presented.The two most powerful cosmic thermal sources: the background (relict) flux in the absolute millimeter maximum of the spectrum, and the mm-wave radio flux from Sun are considered. The postulate of A. Einstein about the emergence of an induced emission quantum in a medium with established thermal equilibrium is taken into account. This made it possible to quantitatively substantiate, based on the principles of the similarity theory of G.S. Golitsyn, a scheme for the use of microwave energy of the interstellar/interplanetary medium during space flights. Based on the physics of collisions, in the proton transfer reaction of the main simple hydrides in interstellar/interplanetary molecular clouds, it is proposed to take into account the possibility of the manifestation of an additional channel for the maser effect in such a medium (first considered by V.A. Ambartsumian in 1979) due to the close location of electronically excited Rydberg levels for molecules in these clouds. The pioneering work of N.S. Kardashev on the study of Rydberg transitions during the emission of recombination radio lines was taken into account. Due to the efforts of astronomers from the Lebedev Physical Institute and the State Astronomical Observatory of the Russian Academy of Sciences (at Pulkovo), this work led to the discovery of the microwave flux from deep space objects. Real energy and schemes for using a microwave quantum propulsor device with the ability to choose the direction of flights are discussed.

A Scoping Review: Ketamine for the Prevention of Perioperative Shivering in Patients Undergoing Spinal Anesthesia
Authors: Goich Kenneth ,   Rowan University, Pastore Dakota B. , Koutsenko Bianna , Infosino Benjamin , Sgrignoli Mitchell
Published: July 2024

Introduction: Shivering is a frequently encountered perioperative complication in patients undergoing spinal anesthesia. Numerous different pharmacological agents have been employed to mitigate this issue. Objective: This scoping review aims to evaluate the efficacy of ketamine in mitigating the incidence of shivering. Methods: "Pubmed," "Jama," and "Cochrane" were used as primary databases. Searches were performed using combinations of key terms: "Ketamine," "Shivering," "Spinal Anesthesia," and "Hypothermia." Results: In ketamine versus control, three out of five studies found ketamine to be more effective (p<0.05, p<0.001, p<0.001) in the prevention of shivering. When compared with tramadol, two studies found ketamine to be more effective (p<0.001, p<0.001), one found no difference (p=0.261), and one found tramadol to be more effective (p<0.001). Two studies found dexmedetomidine more effective (p<0.022, p<0.027) than ketamine and tramadol. When comparing ketamine, ondansetron, and pethidine, all three were effective (P<0.001) versus saline, with no significant difference between the three. Meperidine demonstrated more efficacy (p<0.05) in reducing the intensity of shivering than ketamine. Ketamine's effects on hemodynamics were shown to be equivocal or more favorable across several studies. Conclusion: Ketamine is an effective and safe drug for preventing perioperative shivering. While there is mixed evidence on whether it is better than other treatments, ketamine may have advantages from a hemodynamics standpoint. However, doctors should be cautious when prescribing it to patients who might be prone to delirium due to its association with hallucinations. Overall, ketamine is a safe and effective drug for the prevention of perioperative shivering.

Published: July 2024

In this paper, we investigate the Cournot-Bertrand double oligopoly hybrid competition model proposed by Zhu et al. (2021). By using the central manifold reduction theorem we analyze the structural stability of the model for three fixed points. We show that a subcritical (supercritical) flip bifurcation occurs at first (second and third) fixed point. This reflects that in the market competition, there will be a 2-period cycle between two firms. When subcritical flip bifurcation occurs, the 2-period cycle is unstable and the objective function values of both firms gradually deviates from the cycle. On the contrary, when the supercritical bifurcation occurs, the 2-period cycle is stable, and the objective function values of both firms gradually tend to the stable cycle. We also prove that a transcritical bifurcation will occur at the second fixed point, which indicates that the two firms will present two equilibrium states on both sides of the fixed point in the small neighborhood, but the stability of these two equilibrium states is opposite.

Published: July 2024

The overloading of the ecreteur of the YJ17 cigarette-making machine usually leads to problems such as gearbox damage or a long time spent finding foreign objects. This study aimed to use 3D modeling and digital simulation technology, together with the SolidWorks software, to simulate the speed and force of the transmission part of the ecreteur of the YJ17 cigarette-making machine and investigate the influence of the rotation speed of the main drive shaft, the torque of the ecreteur synchronous belt, and the three characteristic parameters of pressure spring force on the tight head position and the short position rate. A mechanical self-locking overload clutch was designed based on the simulation results to work with the proximity switch to stop the equipment, the fan, and the shredded tobacco return system in case of ecreteur overload and control the debris in a specific area. The clutch effect was quantitatively analyzed through multiparameter simulation. The findings revealed that the overload fault of the ecreteur was processed in 7.4 min, the fault processing efficiency increased by 1046.6%, and the detection accuracy of overload shutdown was 100%. This technology provided technical support for protecting spare parts and shortening the maintenance time when the ecreteur was overloaded.

Published: July 2024

The conversion of forests to pastures in the Amazon results in deforestation and the loss of environmental services. This practice affects biogeochemical cycles and impairs soil enzyme activity, which is essential for maintaining soil quality. This study aimed to investigate the impact of converting part of the Amazon forest into pastures, focusing on soil enzyme activity. The study was conducted at Fazenda Canto Verde, Roraima, comparing native forest areas and pastures of Brachiaria brizantha and Brachiaria humidicola, established on Haplic acrisol, without fertilization or tillage, under a management regime of 30 days of grazing and 60 days of rest. Sampling involved 12 mini trenches per hectare at two depths, with analysis of enzyme activity post-incubation. Higher activity of carbon cycle enzymes (Cellulase, Invertase, β-Glucosidase) was observed in the forest compared to pastures, especially with B. humidicola. Nitrogen cycle enzymes (Urease, BAA-Protease) were more active in the forest, while B. humidicola showed the highest Casein-Protease activity. In the phosphorus and sulfur cycles, the forest led in Phosphomonoesterase and Phosphodiesterase, while B. humidicola excelled in Arylsulfatase. This study demonstrates that replacing forest with pastures significantly alters soil functionality, impacting biogeochemical cycles and their ecological functions.

The influence of anodic potentiostatic treatment of nickel surface in deep eutectic solvents, ethaline and reline (eutectic mixtures of choline chloride with ethylene glycol and urea, respectively), on the electrocatalytic activity in the electrochemical reactions of oxygen evolution and urea oxidation in an aqueous alkaline medium (1 M NaOH) was investigated for the first time. It was shown that, depending on the chosen treatment potential and the nature of the eutectic solvent used, a significant increase in the rate of the studied processes was observed. Specifically, after anodic treatment of nickel under certain conditions, the polarization of the oxygen evolution reaction at a current density of 0.1 A/cm2 could be reduced by approximately 150–200 mV, and the maximum current density of urea oxidation could be increased by an order of magnitude (from 0.012 A/cm2 to 0.131 A/cm2 at a urea concentration of 0.33 mol/dm3 in alkaline solution). The observed increase in electrocatalytic activity after anodic treatment of nickel in deep eutectic solvents is likely related to changes in surface morphology patterns and the nature and concentration of relevant electroactive sites on the electrode surface. The results obtained in this work can be used for the development of highly efficient electrode materials for green hydrogen energy.

This study reports the influence of fly ash on the operational, technological, and physical-mechanical properties of composites based on secondary high-density polyethylene filled with wood flour. It is shown that when calcite is replaced by fly ash in the composite, the operational and technological properties of the material are improved: water absorption, coefficient of linear thermal expansion and technological shrinkage are reduced. When using fly ash as a filler, there is also an increase in the flexural strength of the composite by 9% (from 51.3 MPa in the absence of fly ash to 55.8 MPa in the absence of calcite), but the Charpy impact toughness of samples with cut is decreased by more than 2 times (from 11.9 kJ/m2 to 5.1 kJ/m2, respectively).
