Wall-resolved large-eddy simulation of supercritical airfoil side-edge
 noise

— A wall-resolved compressible large-eddy simulation and wind-tunnel experiments are performed on a finite-span supercitical air-foil to investigate the side-edge flow structures and noise sources. The geometry is composed of an isolated supercritical profile (2% camber, 13% thickness) with finite span. The chordwise Reynolds number is 620,000 and the free-stream Mach number is 0.09. The aerodynamic results obtained with a compressible unstructured Large Eddy Simulation solver show the development of turbulent structures from the boundary layer on the airfoil, along with the trajectory of the primary and secondary vorticies. Surface wall shear stress path-lines are compared with experimental oil-flow visualization results yielding good agreement, especially at flow impingement locations. Wall RMS pressure contours highlight the side-edge shear layer and flow impingement of the primary vortex at the pressure side edge to be important noise generation mechanisms. The Ffowcs Williams and Hawkings analogy is used to compute the far-field noise levels. The aeroacoustics simulation results are then compared to the experimental results.
Compression Sportswear Improves Speed, Endurance, and Functional Motor Performances: A Meta-Analysis

Compression sportswear is widely used for enhancing exercise performances, facilitating recovery, and preventing injuries. Despite prior findings that confirmed positive effects on physical recovery after exercises, whether compression sportswear can enhance exercise performances has not been determined. Thus, this systematic meta-analysis examined the effects of compression sportswear on exercise performances including speed, endurance, strength and power, functional motor performance, and sport-related performance. We calculated effect sizes by comparing changes in exercise performances between the compression garment and the control group. Two additional moderator variable analyses determined whether altered exercise performances were different based on the types of participants and compression sportswear. For the total 769 participants from 42 included studies, the random-effect model found that compression sportswear significantly improved speed, endurance, and functional motor performances. Additional moderator variable analyses identified significant positive effects on speed for athletes, and endurance and functional motor performance for moderately trained adults. Further, whole-body compression garments were beneficial for improving speed, and lower-body compression garments effectively advanced endurance performances. For functional motor performances, both upper- and lower-body suits were effective. These findings suggest that wearing compression sportswear may be a viable strategy to enhance overall exercise performances.
ANALISIS MODIFIKASI SHELL-AND-TUBE HEAT EXCHANGER PADA PENGOLAHAN AIR LIMBAH PT. ANDALAN FURNINDO

Heat exchanger pada proses pengolahan air limbah PT. Andalan Furnindo sering bermasalah. Oleh sebab itu, penulis mencoba untuk memodifikasi desain heat exchanger pada bagian tube, baffle, dan estimasi pressure drop agar mendapat performa yang lebih bagus. Proses pengolahan data dimulai dari memodifikasi dimensi diameter shell, diameter tube, panjang shell, panjang tube, jumlah baffles, jumlah tube dan jenis path aliran fluida. Menghubungkan korelasi antara parameter dengan modifikasi dimensi yang telah dilakukan agar hasil akhir berupa nilai koefisien perpindahan panas dan pressure drop sesuai yang diinginkan. Hasil perhitungan perancangan dengan Dsid =1 m; di = 0,02 m; do = 0,025 m; panjang shell dan tube=4,6 m; B=5; Nt=1176 dan path aliran U adalah menghasilkan Uc=683 dan Uf=569 ; =1691,3 Pa; dan =1276,6 Pa. Dengan memodifikasi diameter tube dan shell yang lebih besar dari setelan pabriknya dapat memudahkan proses perawatan unit dalam hal membersihkan kotoran dalam tube maupun dalam shell. Sehingga performanya stabil, umur pemakaian unit lebih lama, dan waktu perawatan selanjutnya terjadwal dengan baik. Heat exchanger in the waste water treatment process of PT. Andalan Furnindo is frequently in trouble. Therefore, the authors try to modify the heat exchanger design on the tube, baffle, and estimated pressure drop in order to get better performance. The data processing starts from modifying the dimensions of shell diameter, tube diameter, shell length, tube length, number of baffles, number of tubes and type of fluid flow path. Linking the correlation between parameters with dimensional modifications that have been done so that the final result is the value of the heat transfer coefficient and pressure drop as desired. The results of design calculations with Dsid =1 m; di = 0,02 m; do = 0,025 m; length of shell and tube = 4.6 m; B=5; Nt=1176 and the flow path U is to produce Uc=683 dan Uf=569 ; =1691,3 Pa; dan =1276,6 Pa. By modifying the tube and shell diameter which is larger than the factory setting, it can facilitate the unit maintenance process in terms of cleaning dirt in the tube and in the shell. So that the performance is stable, the service life of the unit is longer, and the next maintenance time is properly scheduled.
Adsorption Behaviors of Lanthanum (III) and Yttrium (III) Ions on Gibbsite

The enrichment process of rare earth elements in ion-adsorbed rare earth ores and bauxite is potentially related to the adsorption of rare earth elements by gibbsite. In this paper, lanthanum and yttrium were selected as surrogates of light rare earth elements and heavy rare earth elements, respectively. The effects of adsorption time, solution pH, and background electrolyte concentration on the adsorption of rare earth ions by gibbsite were investigated through batch adsorption experiments. The results showed that the adsorption of rare earth ions by gibbsite can approach equilibrium in 72 h. There is mainly electrostatic repulsion between gibbsite and rare earth ions at pH 4–7, and the adsorption efficiency increases with the increase in solution pH value and background electrolyte concentration. The adsorption process of rare earth ions by gibbsite is more consistent with the pseudo-second-order kinetic and Langmuir single-layer adsorption models. Moreover, based on the structural correlation between clay minerals and gibbsite, the causes for the differences in the adsorption behaviors of rare earth elements on the minerals are discussed. The results of this study help to understand the role of aluminum hydroxide in the migration and fate of rare earth elements in epigenetic environments.

Total Breast Reconstruction with Fat Grafting Combined with Internal Tissue Expansion

Summary: Breast reconstruction procedures are currently performed as standard practice and are an integral part of breast cancer treatment. The advantages and disadvantages of particular types of reconstruction are well known. Most of them require the woman to accept a different consistency of the reconstructed breast, as is the case with implants, or to have extra scarring in the donor site and a cutaneous island with a different texture in the recipient site, as is the case with TRAM, DIEP, and other flaps. This article presents the concept of breast reconstruction with fat grafting combined with internal tissue expansion. A 44-year-old woman after a right mastectomy for invasive carcinoma T1c, N0 (IIB) was presented. After unsatisfactory treatment with fat grafting supported by BRAVA system, she was qualified for breast reconstruction with fat grafting combined with tissue expansion. An anatomic 350 cm3 breast expander with an integrated port was implanted. It was filled with saline solution up to volume of 380 ml. Then, 7 fat grafting procedures combined with gradual emptying of the expander were performed. The 50/70 principle was used, that is, 50 ml of physiological saline was removed from the expander and 70 ml of fat was injected into the subcutaneous tissue over the expander. Finally, the expander was removed and a satisfactory volume and completely natural consistency of the breast was obtained. Breast reconstruction with fat grafting combined with tissue expansion is a promising method of total breast reconstruction after mastectomy.
Benthic algae as major precursors of oil-prone kerogen – A case study from the Hungarian Middle Miocene

This study is intended to clarify the depositional environment of a 180-m-thick, immature, limy Middle Miocene oil source rock interval, cored in the Zala Basin, western Hungary. For this purpose, a highly interdisciplinary approach was applied combining simple, standard micropaleontological, isotopic, and organic geochemical methods, rarely applied together. Foraminifera were studied for estimating bottom oxygenation and water depth, while nannoplankton biostratigraphy permitted for estimating the rate of sedimentation. The studied source rocks were deposited in a rather shallow sea, below well-oxygenated bottom water. The abundant epiphytic foraminiferal fauna proves that the bottom was densely inhabited by benthic algae, while the high δ13Corg (>–22‰) clearly indicates massive benthic algal contribution to the kerogen. Mass accumulation rate of the limy upper part of the NN5 nannoplankton biozone, the oil source interval included, was very high (551 t/m2/Ma). In spite of moderate productivity and good .

GDP-related emission targets weaknesses: the case of Argentina

GDP linked targets have the potential to favor green growth and avoid “hot air” in uncertain backgrounds, like those of many developing economies. Even if they are not a guarantee of emissions reduction as required by the 2 degree Celsius Copenhagen goal because emissions´ intensity can decrease even when emissions do not. A few countries have submitted at some point of international negotiations a target based on this type of metric. Argentina is one of them, together with Chile, China, India, Singapore, Tunisia, Uruguay and Turkmenistan. As is the case of all target forms, it requires good monitoring and forecast of emissions. But, as the literature has shown, one of the GDP-related target weaknesses is that it relies on a second indicator: the GDP. This article shows concretely how GDP biases influence intensity targets monitoring, using as a base the case of Argentina.
Mesenchymal Stem Cell-Derived Exosomal microRNAs in Cardiac Regeneration

Mesenchymal stem cell (MSC)-based therapy is one of the most promising modalities for cardiac repair. Accumulated evidence suggests that the therapeutic value of MSCs is mainly attributable to exosomes. MSC-derived exosomes (MSC-Exos) replicate the beneficial effects of MSCs by regulating various cellular responses and signaling pathways implicated in cardiac regeneration and repair. miRNAs constitute an important fraction of exosome content and are key contributors to the biological function of MSC-Exo. MSC-Exo carrying specific miRNAs provides anti-apoptotic, anti-inflammatory, anti-fibrotic, and angiogenic effects within the infarcted heart. Studying exosomal miRNAs will provide an important insight into the molecular mechanisms of MSC-Exo in cardiac regeneration and repair. This significant information can help optimize cell-free treatment and overcome the challenges associated with MSC-Exo therapeutic application. In this review, we summarize the characteristics and the potential mechanisms of MSC-derived exosomal miRNAs in cardiac repair and regeneration.
Hybrid Cross-Transformer-KPConv for Point Cloud Segmentation

Point cloud segmentation is one of the challenging areas due to its disorder and irregularity. Currently, a lot of work utilising Transformer instead of conventional convolution methods has been proposed, which can well cope with these difficulties and is suitable for point cloud segmentation tasks. However, most existing Transformer methods extract global or local features in isolation, failing to obtain rich contextual information. In this letter, a cross-scale Transformer network for feature extration is proposed. Multi-level contextual information is captured appllying FPS algorithm. Integrated with point cloud convolution method, achieving excellent segmentation performance. Extensive experiments on SemanticKITTI dataset demonstrate the superior performance of the proposed method on mIoU.
Effect of Comprehensive and Integrative Medical Services on Patients with Degenerative Lumbar Spinal Stenosis: A Pilot Study

Background and Objectives: Two types of medicinal systems are available in Korea: Western and oriental. These exist as separate services that independently provide medical care to patients. We determined the utility and benefits of compressive and integrated medical services (CIMS) comprising 12 sessions of acupuncture and healing programs over 6 weeks. Methods and Methods: In this two-group parallel single-center randomized controlled assessor-blinded trial, 25 participants were assigned to either the experimental (conventional medical treatment plus CIMS, n = 12) or control (conventional medical treatment, n = 13) group. Spinal nerve root block was performed on the compressed spinal nerve root (identified using magnetic resonance imaging) when no improvement was observed after the initial treatment. The experimental group received 12 cycles of acupuncture and manual therapy for 6 weeks; the control group received conventional medical treatment alone. Results: The average age of participants in the experimental and control groups was 70.73 ± 5.95 and 67.33 ± 8.89 years, respectively. There were no significant differences between the groups in terms of age, body mass index, Leeds Assessment of Neuropathic Symptoms and Signs, sex, and current medical history. We found high compliance for both programs (acupuncture and healing). On exclusion of between-group effects, the visual analog scale (VAS) score improved significantly over time (p = 0.045). Further, comparison of the groups after excluding the effects of visits revealed significantly lower VAS scores in the experimental group than in the control group (p = 0.000). Conclusions: Patients with degenerative lumbar spinal stenosis who mainly complain of radiating pain in the lower leg may benefit from CIMS after spinal nerve root block for ≤3 months after treatment. Our study findings suggest that this treatment improves spinal function and Oswestry Disability Index score. However, CIMS did not improve QoL.

Beyond the Basics: Unraveling the Complexity of Coronary Artery Calcification

Coronary artery calcification (CAC) is mainly associated with coronary atherosclerosis, which is an indicator of coronary artery disease (CAD). CAC refers to the accumulation of calcium phosphate deposits, classified as micro- or macrocalcifications, that lead to the hardening and narrowing of the coronary arteries. CAC is a strong predictor of future cardiovascular events, such as myocardial infarction and sudden death. Our narrative review focuses on the pathophysiology of CAC, exploring its link to plaque vulnerability, genetic factors, and how race and sex can affect the condition. We also examined the connection between the gut microbiome and CAC, and the impact of genetic variants on the cellular processes involved in vascular calcification and atherogenesis. We aimed to thoroughly analyze the existing literature to improve our understanding of CAC and its potential clinical and therapeutic implications.
IR camera system with an advanced image processing technologies

We have developed image processing technologies for resolving issues caused by the inherent UFPA (uncooled focal plane array) sensor characteristics to spread its applications. For example, large time constant of an uncooled IR (infra-red) sensor limits its application field, because motion blur is caused in monitoring the objective moving at high speed. The developed image processing technologies can eliminate the blur and retrieve almost the equivalent image observed in still motion. This image processing is based on the idea that output of the IR sensor is construed as the convolution of radiated IR energy from the objective and impulse response of the IR sensor. With knowledge of the impulse response and moving speed of the objective, the IR energy from the objective can be de-convolved from the observed images. We have successfully retrieved the image without blur using the IR sensor of 15 ms time constant under the conditions in which the objective is moving at the speed of about 10 pixels/60 Hz. The image processing for reducing FPN (fixed pattern noise) has also been developed. UFPA having the responsivity in the narrow wavelength region, e.g., around 8 μm is appropriate for measuring the surface of glass. However, it suffers from severe FPN due to lower sensitivity compared with 8–13 μm. The developed image processing exploits the images of the shutter itself, and can reduce FPN significantly.
Influence of polymorphisms in TNF-α and IL1β on susceptibility to alcohol induced liver diseases and therapeutic potential of miR-124-3p impeding TNF-α/IL1β mediated multi-cellular signaling in liver microenvironment

Background and aims Alcoholic liver disease (ALD) is the leading cause of the liver cirrhosis related death worldwide. Excessive alcohol consumption resulting enhanced gut permeability which trigger sensitization of inflammatory cells to bacterial endotoxins and induces secretion of cytokines, chemokines leading to activation of stellate cells, neutrophil infiltration and hepatocyte injury followed by steatohepatitis, fibrosis and cirrhosis. But all chronic alcoholics are not susceptible to ALD. This study investigated the causes of differential immune responses among ALD patients and alcoholic controls (ALC) to identify genetic risk factors and assessed the therapeutic potential of a microRNA, miR-124-3p. Materials and methods Bio-Plex Pro™ Human Chemokine analysis/qRT-PCR array was used for identification of deregulated immune genes. Sequencing/luciferase assay/ELISA detected and confirmed the polymorphisms. THP1 co-cultured with HepG2/LX2/HUVEC and apoptosis assay/qRT-PCR/neutrophil migration assay were employed as required. Results The combined data analysis of the GSE143318/Bio-Plex Pro™ Human Chemokine array and qRT-PCR array revealed that six genes (TNFα/IL1β/IL8/MCP1/IL6/TGFβ) were commonly overexpressed in both serum/liver tissue of ALD-patients compared to ALC. The promoter sequence analysis of these 6 genes among ALD (n=322)/ALC (n=168) samples revealed that only two SNPs, rs361525(G/A) at -238 in TNF-α/rs1143627(C/T) at -31 in IL1β were independently associated with ALD respectively. To evaluate the functional implication of these SNPs on ALD development, the serum level of TNF-α/IL1β was verified and observed significantly higher in ALD patients with risk genotypes TNF-α-238GA/IL1β-31CT+TT than TNF-α-238GG/IL1β-31CC. The TNF-α/IL1β promoter Luciferase-reporter assays showed significantly elevated level of luciferase activities with risk genotypes -238AA/-31TT than -238GG/-31CC respectively. Furthermore, treatment of conditioned medium of TNF-α/IL1β over-expressed THP1 cells to HepG2/LX2/HUVEC cells independently showed enhanced level of ER stress and apoptosis in HepG2/increased TGFβ and collagen-I production by LX2/huge neutrophil infiltration through endothelial layer. However, restoration of miR-124-3p in THP1 attenuated such inter-cellular communications and hepatocyte damage/collagen production/neutrophil infiltration were prohibited. Target analysis/luciferase-reporter assays revealed that both TNF-α/IL1β were inhibited by miR-124-3p along with multiple genes from TLR4 signaling/apoptosis/fibrogenesis pathways including MYD88, TRAF3/TRADD, Caspase8/PDGFRA, TGFβR2/MCP1, and ICAM1 respectively. Conclusion Thus, rs361525(G/A) in TNF-α and rs1143627(C/T) in IL1β gene may be used as early predictors of ALD susceptibility among East Indian population. Impeding overexpressed TNF-α/IL1β and various genes from associated immune response pathways, miR-124-3p exhibits robust therapeutic potential for ALD patients.
