Overcoming Boundary-Layer Separation with Distributed Propulsion
Authors: Suppes Adam Bradford , Suppes Galen 
Published: December 2024

Strategically located propulsors are able to create constructive interference on aircraft; increasing lift, lift-drag ratios (L/D), and resilience to boundary layer separation. Computational fluid dynamic (CFD) studies teach toward an optimal configuration with a near-zero upper-surface pitch in front of a trailing section propulsor followed by a trailing taper with 20° to 45° surface pitch from the propulsor to a trailing edge near the bottom of the lifting body (“Lift Span Tech”). Applications benefiting from Lift Span Tech range from box trucks to high-speed intercontinental transit. With initial propulsor power mitigating boundary layer separation, Lift Span Tech provides a high gain:loss, where the gain is in reduced drag and loss is reduced thrust from the propulsor. Performance may be augmented with ground effect further improving L/D efficiency. This study evaluates the sensitivity of performance to different CFD turbulence models and trailing taper pitches. While today’s commercial approaches can reduce truck drag by about 34% with no impact on wheel friction, new Lift Span Tech is able to reduce drag by up to 84% and wheel friction by up to 90%. The technology enables designs to allow direct solar power to fully replace liquid fuels in a wide range of vehicles.

Published: December 2024

Monitoring and controlling water temperature and pH levels are crucial aspects in maintaining a healthy environment for breeding Arowana fish. Arowana fish are sensitive to fluctuations in water temperature and pH levels, which can lead to stress, diseases, and even death. Therefore, it is essential to regularly monitor and maintain the temperature and pH levels within suitable ranges for the fish. This study aims to develop Internet of Things (IoT) technology that is expected to assist Arowana fish farmers in monitoring and controlling more effectively and practically. The methodology employed in this study is a case study approach, with Arowana fish farmers as respondents. In monitoring the water quality for Arowana fish, many farmers still rely on traditional farming models that heavily depend on experience, lacking the ability to assess water quality and environmental changes scientifically. By utilizing LoRa and cellular technologies, this study provides intelligent solutions for water quality monitoring to create controlled and sustainable growth conditions. The ultimate outcome of this research is the development of an IoT-based application designed to enhance the efficiency of Arowana fish farming. This application involves automatic control of water pH and temperature in three different treatments. The methodology employed in the application design involves the development of an IoT-based system integrated with temperature and pH sensors. The functionality of the application includes real-time monitoring and automatic control of the aquarium environment. Testing was conducted through a series of field trials to ensure system performance and reliability. With a pH range of 6.5 - 7.5 and temperature range of 26 - 30°C, this application has proven to provide optimal responses for Arowana fish farming, enhancing growth and reducing feeding time.

Gut Microbiota, Circulating Metabolites and Risk of Endometriosis: A Two-Step Mendelian Randomization Study
Authors: Yang Hua 
Published: December 2024

Abstract
Epidemiological studies and animal models have suggested a possible link between gut microbiota (GM), circulating metabolites, and endometriosis (EMs) pathogenesis. However, whether these associations are causal or merely due to confounding factors remains unclear. We conducted a two-sample and two-step Mendelian randomization (MR) study to elucidate the potential causal relationship between GM and EMs, and the mediating role of circulating metabolites. Our MR analysis revealed that higher abundances of class Negativicutes, and order Selenomonadales, as well as genera Dialister, Enterorhabdus, Eubacterium xylanophilum group, Methanobrevibacter were associated with an increased risk of EMs (Odds Ratio (OR) range: 1.0019–1.0037). Conversely, higher abundances of genera Coprococcus 1 and Senegalimassilia were linked to reduced risk of EMs (OR range: 0.9964–0.9967). Additionally, elevated levels of circulating metabolites such as 1-eicosatrienoyl-glycerophosphocholine and 1-oleoylglycerophosphocholine were found to be associated with heightened risk of EMs (OR range: 2.21–3.16), while higher concentrations of 3-phenylpropionate and dihomo-linolenate were protective (OR range: 0.285–0.535). Two-step MR analysis indicated that specific microbial taxa, notably genus Enterorhabdus and order Selenomonadales, might function as mediators linking circulating metabolites to the risk of EMs. Our findings suggest a probable causal relationship between GM, circulating metabolites, and EMs, indicating that GM may mediate the influence of circulating metabolites on the pathophysiology of EMs. These results offer new leads for future mechanistic studies and could inform clinical translational research.

Authors: Sadiq Nazer Rana , Abdulmohsin Ali Omar 
Published: December 2024

Purpose: The research aims to estimate models representing phenomena that follow the logic of circular (angular) data, accounting for the 24-hour periodicity in measurement.
Theoretical framework: The regression model is developed to account for the periodic nature of the circular scale, considering the periodicity in the dependent variable y, the explanatory variables x, or both.
Design/methodology/approach: Two estimation methods were applied: a parametric model, represented by the Simple Circular Regression (SCR) model, and a nonparametric model, represented by the Nadaraya-Watson Circular Regression (NW) model. The analysis used real data from 50 patients at Al-Kindi Teaching Hospital in Baghdad.
Findings: The Mean Circular Error (MCE) criterion was used to compare the two models, leading to the conclusion that the Nadaraya-Watson (NW) circular model outperformed the parametric model in estimating the parameters of the circular regression model.
Research, Practical & Social Implications: The recommendation emphasized using the Nadaraya-Watson nonparametric smoothing method to capture the nonlinearity in the data.
Originality/value: The results indicated that the Nadaraya-Watson circular model (NW) outperformed the parametric model.

Assessment of the authenticity of horse chestnut (Aesculus hippocastanum L.) flowers by scanning electron microscopy
Authors: Dunilin A. D. , Trineeva O. V. 
Published: December 2024

Introduction. Horse chestnut (Aesculus hippocastanum L.) is a plant widely used in official and folk medicine in many countries. Pharmacopoeia raw materials in the Russian Federation are only horse chestnut seeds. Flowers, due to the fraction of phenolic derivatives and triterpene saponins contained in them, are a promising medicinal plant raw material, presumably having a venotonizing and membrane-protective effect. To obtain medicinal herbal preparations based on horse chestnut flowers, it is required to have regulatory documentation containing a list of quality indicators, including a description of the signs of its authenticity (morphology and anatomy). Scanning electron microscopy is one of the advanced methods that have recently been increasingly used in medicine and pharmacognostic analysis. Unlike light microscopy, the method provides a three-dimensional spatial representation of diagnostically significant signs of medicinal plant raw materials.Aim. The aim of the study was to study the morphology of the surface of horse chestnut flowers by scanning electron microscopy.Materials and methods. The object of the study was dried whole flowers of horse chestnut (Aesculus hippocastanum L.), collected in the Voronezh region in 2023 at the beginning of flowering. The pieces of flowers were pre-sprayed with silicon on an automatic spraying unit Q150R ES (Quorum Technologies Ltd., Great Britain). Micrographs were obtained using the JSM-6510LV electron microscope (JEOL Ltd., Japan).Results and discussion. The micrographs obtained during the analysis showed diagnostically significant features of the flower structure: the epidermal cells of the corolla petals are polygonal, irregularly shaped, some elongated with sinuous folds. Pollen grains can be collected in cluster-like clusters, located separately or found singly. The surface of the corolla petal is covered with numerous often twisting hairs having a rough-warped structure and a cone-shaped base with a clearly defined attachment point. The surface of the staminate filaments is striated, with longitudinal folds with single unicellular hairs. The anther has a folded shape, its surface is lined with scaly epidermal cells with rough and thickened walls. The surface of the calyx, including the pedicel, is also densely pubescent with numerous trichomes.Conclusion. The scanning electron microscopy method was used for the first time to study the morphological and anatomical features of horse chestnut flowers. The structure of the main diagnostically significant structures of this LRS has been clarified. The morphology of the epidermis surface of the petals of the corolla and calyx, trichomes, pollen filaments, anthers and pollen grains of flowers has been determined. It has been established that carbon and oxygen are the predominant elements of the raw materials.

BackgroundTo evaluate the feasibility, effectiveness and assistant effect of 3D printed aortic model in the treatment on congenital coarctation of the aorta (CoA) in adolescents and adults.MethodsFrom December 2018 to December 2023, a total of 10 patients with congenital coarctation of aorta underwent percutaneous balloon dilatation covered stent implantation in the department of cardiovascular surgery, Xijing Hospital. There were 6 males and 4 females whose average age was (27.68 ± 13.45) years. One case complicated with ventricular septal defect (VSD). The CT data of aorta were collected before operation, and the aorta was reconstructed by Mimics software and printed with 3D printing technology. The operation simulation was performed before operation to determine the best operation plan. The clinical data during hospitalization and follow-up were analyzed.ResultsAll the patients of CoA were successfully treated with percutaneous balloon dilatation covered stent implantation. The narrowest average diameter of CoA increased from (4.35 ± 2.61) mm before operation to (16.84 ± 1.99) mm immediately after operation (P &lt; 0.05). The mean transconstrictive systolic pressure difference decreased from (81.29 ± 18.72) mmHg before operation to (15.52 ± 7.47) mmHg after operation (P &lt; 0.05). The mean systolic blood pressure of the right upper limb decreased from (182.05 ± 38.99) mmHg preoperatively to (141.95 ± 32.11) mmHg postoperatively (P &lt; 0.05). The mean systolic blood pressure of the lower limb increased from (121.52 ± 27.84) mmHg preoperatively to (131.81 ± 32.39) mmHg postoperatively (P &lt; 0.05). Two patients with PDA and VSD underwent interventional occlusion at the same time without shunt. During the period of hospitalization and follow-up, there were significant cardiovascular complications.ConclusionsPercutaneous balloon dilatation covered stent implantation is effective in the treatment of adolescents and adults with CoA in the short and medium term, with fewer complications, and the long-term effect needs furthshdie1er study.
