Effect of Multiple Grooves on Aerodynamic Performance of a Low Reynolds Number UAV Propeller (Part I)
Authors: SEENI Aravind
Published: June 2023

In a continuation of work previously performed by the author on grooved propellers, numerical investigations are performed on Applied Precision Composites 10×7 Slow Flyer propeller.
Computational Fluid Dynamics is used to analyze the novel propeller design. The grooved sections considered have a rectangular geometry measuring 0.1×0.1mm and are interchangeably located at
0.09c, 0.17c, 0.32c and 0.42c from the leading edge in a dual grooved configuration. The results of the study showed that the presence of grooves had modified the flow characteristics only to detrimentally
impact the thrust performance. However, the grooves improved power performance due to torque reduction. The analysis of the results showed that, for most models, there is lower torque relative to the baseline in the low-to-medium advance ratio operating range. The improvement in torque however, did not improve efficiency in the models.
Magnetic field caused enhanced absorption and circular dichroism of an achiral plasmonic nanostructure
Authors: Ikram Muhammad , Li Ying , Zhang Zhongyue
Published: June 2023

In this paper, modulation of light–matter interactions by a magnetic field is used to generate circular dichroism (CD) from an achiral plasmonic nanostructure. Theoretical investigations show an increase in light absorption by the nanostructure in the presence of a magnetic field. The achiral nanostructure exhibits CD in external magnetic field parallel to circularly polarized light (CPL) incidence. The CD emergence is caused by modulation of electron motion to reduced/enhanced frequencies under CPL incidence. Compared to previous studies, in this paper the mechanism of CD emergence, and the physical reasoning behind the change in CD due to change in magnetic field direction and intensity, are explained. CD intensity increases with increasing magnetic field intensity, while CD sign changes on magnetic field direction reversal. Varying structural parameters significantly influences CD intensity. This study can be helpful in magneto-optics and in magneto-chiral applications.

Authors: Xing Linzhuang , Wang Ruipeng , Ha Yuan , Li Zhimin
Published: June 2023

Achieving high solar energy absorption based on nanofluids (NFs) needs further study in solar photothermal conversion technology. In this work, we performed COMSOL simulations to investigate the solar energy absorption using a core-shell nanostructure composed of the Au core and shell with different materials. The influence of the radius of the Au core, the materials of the shell, and the shell thickness on the solar absorption efficiency factor (SAEF) are systematically studied. The results show that the SAEF of the Au@Li nanoparticle with ratio of 0.5 has the highest SAEF of 1.4779, increasing 1.99 times compared to that of the bare Au nanoparticle of 0.74326 with the same radius. Moreover, the optical properties, electric field distribution, and SAEF of the Au@Li dimer are further evaluated to demonstrate the aggregation effects on SAEF. We find that the SAEF of the Au@Li dimer reaches the maximum of 4.34 with a distance around 1 nm, where the LSPR coupling effect in the nanogap is sharply enhanced 700 times irradiated by light with wavelength of 760 nm. Finally, the direct absorber solar collector performance demonstrates that Au@Li dimer NFs can collect 93% of solar energy compared to 54% for Au@Li NFs and 51% for Au NFs. This work provides the possibility to achieve more efficient solar thermal conversion, and may have potential applications in efficient solar energy harvesting and utilization.

Published: June 2023

Dynamic full-field optical coherence tomography (D-FFOCT) has recently emerged as an invaluable live label-free and non-invasive imaging modality able to image subcellular biological structures and their metabolic activity within complex 3D samples. However, D-FFOCT suffers from fringe artefacts when imaging near reflective surfaces and is highly sensitive to vibrations. Here, we present interface Self-Referenced (iSR) D-FFOCT, an alternative configuration to D-FFOCT that takes advantage of the presence of the sample coverslip in between the sample and the objective by using it as a defocused reference arm, thus avoiding the aforementioned artefacts. We demonstrate the ability of iSR D-FFOCT to image 2D fibroblast cell cultures, which are among the flattest mammalian cells.
Feasibility of deep learning-based polarization-sensitive optical coherence tomography angiography for imaging cutaneous microvasculature
Authors: Pan Moning , Wang Yuxing , Gong Peijun , Wang Qiang , Cense Barry
Published: June 2023

Polarization-sensitive optical coherence tomography (PS-OCT) measures the polarization states of the backscattered light from tissue that can improve angiography based on conventional optical coherence tomography (OCT). We present a feasibility study on PS-OCT integrated with deep learning for PS-OCT angiography (PS-OCTA) imaging of human cutaneous microvasculature. Two neural networks were assessed for PS-OCTA, including the residual dense network (RDN), which previously showed superior performance for angiography with conventional OCT and the upgraded grouped RDN (GRDN). We also investigated different protocols to process the multiple signal channels provided by the Jones matrices from the PS-OCT system to achieve optimal PS-OCTA performance. The training and testing of the deep learning-based PS-OCTA were performed using PS-OCT scans collected from 18 skin locations comprising 16,600 B-scan pairs. The results demonstrated a moderately improved performance of GRDN over RDN, and of the use of the combined signal from the Jones matrix elements over the separate use of the elements, as well as a similar image quality to that provided by speckle decorrelation angiography. GRDN-based PS-OCTA also showed ∼2-3 times faster processing and improved mitigation of tissue motion as compared to speckle decorrelation angiography, and enabled fully automatic processing. Deep learning-based PS-OCTA can be used for imaging cutaneous microvasculature, which may enable easy adoption of PS-OCTA for preclinical and clinical applications.
Relevance and utility of the in-vivo and ex-vivo optical properties of the skin reported in the literature: a review [Invited]
Authors: Setchfield Kerry , Gorman Alistair , Simpson A. Hamish R. W. , Somekh Michael G. , Wright Amanda J.
Published: June 2023

Imaging non-invasively into the human body is currently limited by cost
(MRI and CT scan), image resolution (ultrasound), exposure to ionising
radiation (CT scan and X-ray), and the requirement for exogenous
contrast agents (CT scan and PET scan). Optical imaging has the
potential to overcome all these issues but is currently limited by
imaging depth due to the scattering and absorption properties of human
tissue. Skin is the first barrier encountered by light when imaging
non-invasively, and therefore a clear understanding of the way that
light interacts with skin is required for progress on optical medical
imaging to be made. Here we present a thorough review of the optical
properties of human skin measured in-vivo and compare
these to the previously collated ex-vivo
measurements. Both in-vivo and
ex-vivo published data show high inter- and
intra-publication variability making definitive answers regarding
optical properties at given wavelengths challenging. Overall,
variability is highest for ex-vivo absorption
measurements with differences of up to 77-fold compared with 9.6-fold
for the in-vivo absorption case. The impact of this
variation on optical penetration depth and transport mean free path is
presented and potential causes of these inconsistencies are discussed.
We propose a set of experimental controls and reporting requirements
for future measurements. We conclude that a robust
in-vivo dataset, measured across a broad spectrum of
wavelengths, is required for the development of future technologies
that significantly increase the depth of optical imaging.
Improving performance prediction of diode end-pumped solid-state Nd:YAG rod amplifiers by incorporating pump mode evolution
Authors: Harrison Justin , Forbes Andrew , Naidoo Darryl
Published: June 2023

Master Oscillator Power Amplifier (MOPA) systems find extensive use in laser development to increase the optical power of laser emissions from a Master Oscillator (MO). Commonly used are the cylindrical rod MOPAs that are optically excited using a multimode fiber-coupled (FC) diode laser emission in an end-pumped configuration. Current analytical 3D models that incorporate thermal effects, gain saturation, and iterative Fourier beam propagation methods, collectively, rely on static approximations of the evolution of the FC pump beam profile over the longitudinal volume of the amplifier crystal. Furthermore, in general, the spectral behavior of the FC diode emission is assumed to be static, and the thermal wavelength shift is not accounted for in the simulation. In this work, we demonstrate a novel approach for accurate modeling of the multimode FC pump beam emission as a complex field using a phase-only Gaussian to flat-top (FT) diffractive optical element, thus allowing for the inclusion of the pump beam into the iterative propagation method. Additionally, we present a method for precise calibration of the model using simple experimental measurements of the diode emission spectrum. The theoretical model is experimentally validated using an end-pumped Nd:YAG crystal rod to perform single-pass amplification of a Gaussian beam, showing excellent agreement with predicted output powers over the calibrated range of pump powers. Furthermore, we provide experimental data that exhibits a strong correlation between the Gaussian to FT phase-only transformation and the multimode FC diode evolution in free-space propagation.
Controlling photons by phonons via giant atom in a waveguide QED setup
Authors: Li Xinyu , Zhao Wei , Wang Zhihai
Published: June 2023

We investigate the single photon scattering in a phonon-photon hybrid system in the waveguide quantum electrodynamics (QED) scheme. In our consideration, an artificial giant atom, which is dressed by the phonons in a surface acoustic wave resonator, interacts with a coupled resonator waveguide (CRW) nonlocally via two connecting sites. Together with the interference effect by the nonlocal coupling, the phonon serves as a controller to the transport of the photon in the waveguide. On the one hand, the coupling strength between the giant atom and the surface acoustic wave resonator modulates the width of the transmission valley or window in the near resonant regime. On the other hand, the two reflective peaks induced by the Rabi splitting degrade into a single one when the giant atom is large detuned from the surface acoustic resonator, which implies an effective dispersive coupling. Our study paves the way for the potential application of giant atoms in the hybrid system.
General approach of terahertz achromatic quarter-wave plate composed of stacked quartz plates
Authors: Zhang Tianmiao , Kropotov Grigory , Khodzitsky Mikhail
Published: June 2023

Typical waveplates are limited to specific frequencies. We propose a general design of a series of THz achromatic quarter-wave plates that work for different frequency range. The simplified formulas and the basic parameters that are used to calculate the thicknesses and rotating angles with the possibility of choosing the frequency range are provided. The main feature of the design is that the number of the x-cut quartz plates is equal to the frequency expansion factor (f
max
/f
min
) of the resulting waveplate, and by altering the thicknesses of quartz plates following a specific pattern only, the frequency range of the waveplate can be shifted. Two achromatic waveplates working in the frequency range of 0.2-0.6 THz and 0.2-1.2 THz were manufactured for testing. The measurement result demonstrates the reliability of the proposed design.

Published: June 2023

In this paper, we demonstrate a technique for measuring the thermally induced phase of a beam by using the Gerchberg-Saxton algorithm. It is shown that the method performs well when measuring optically transparent and highly scattering media, and also that it can be used to make comparative characteristics of different samples absorption coefficients and to measure the aberrations of the output beam. The dependence of the thermal lens dioptric power on the radiation power was investigated in a TGG crystal and ceramic Tb₂O₃, and a comparison of the thermal effects was made. Additionally, the possibility of estimating of the aberrations of thermal lenses was shown.

Authors: Hu Guorong , Greene Joseph , Zhu Jiabei , Yang Qianwan , Li Yunzhe , Alido Jeffrey , Guo Ruipeng , Tian Lei
Published: June 2023

HiLo microscopy is a widefield microscopy technique that provides optical sectioning by computationally combining two images, one with structured illumination and one with uniform illumination. The structured illumination can be achieved by various methods, such as speckle and periodic grids. In this work, we present a novel HiLo strategy that uses an off-the-shelf holographic diffuser and a low-coherence LED source to create random caustic patterns. This method has several advantages over existing ones, such as simplicity and cost-effectiveness. We achieve 4.5 µm optical sectioning capability and demonstrate the performance of our method by imaging a thick and highly scattering brain section. We anticipate that our caustic-based structured illumination approach will enhance the versatility of HiLo microscopy and extend to various imaging applications.
The relation between Self-Control, Need for Cognition and Action Orientation in secondary school students: A conceptual replication study
Authors: Colling Jonne , Wollschläger Rachel , Keller Ulrich , Grass Julia , Strobel Anja , Preckel Franzis , Fischbach Antoine
Published: June 2023

Self-Control can be defined as the self-initiated effortful process that enables individuals to resist temptation impulses. It is relevant for conducting a healthy and successful life. For university students, Grass et al. found that Need for Cognition as the tendency to engage in and enjoy thinking, and Action Orientation as the flexible recruitment of control resources in cognitively demanding situations, predict Self-Control. Further, Action Orientation partially mediated the relation between Need for Cognition and Self-Control. In the present conceptual replication study, we investigated the relations between Self-Control, Need for Cognition, and Action Orientation in adolescence (N = 892 9th graders) as a pivotal period for the development of self-control. We replicated the findings that Need for Cognition and Action Orientation predict Self-Control and that Action Orientation partially mediates the relation between Need for Cognition and Self-Control. In addition, Action Orientation moderates the relation between Need for Cognition and Self-Control. This result implies that in more action-oriented students Need for Cognition more strongly predicted Self-Control than in less action-oriented students. Our findings strengthen theoretical assumptions that Need for Cognition and Action Orientation are important cognitive and behavioral mechanisms that contribute to the successful exertion of Self-Control.

Authors: Al-Mubarak Abdullah I. A. , Hussen Jamal , Kandeel Mahmoud , Al-Kubati Anwar A. G. Al-Kubati , Falemban Baraa , Hemida Maged Gomaa
Published: June 2023

Background and Aim: Avian metapneumovirus (aMPV) is a recently discovered respiratory virus in chickens. Avian metapneumovirus has been linked to respiratory syndromes, reproductive failure in affected chickens and turkeys, swollen head syndrome in chickens, and rhinotracheitis in turkeys. Wild birds are considered potential reservoirs of aMPV, particularly aMPV-C. However, little is known about the prevalence of aMPV in Saudi Arabia. Considering the relevance of backyard chickens in the transmission and sustainability of certain avian viral diseases, this study aimed to assess aMPV exposure in backyard chickens and wild birds circulating near selected locations.

Materials and Methods: We collected 368 serum samples from unvaccinated backyard chickens in ten locations in Eastern Saudi Arabia. Furthermore, we collected 78 serum samples from species of free-ranging birds belonging to the Columbidae family, such as pigeons and doves, captured from the same areas. Using commercial enzyme-linked immunosorbent assay kits, we tested the sera of domestic backyard chickens and wild birds for antibodies against aMPV.

Results: Our results showed that 74/368 birds were positive for aMPV-related antibodies. Conversely, none of the tested wild birds seroconverted to aMPV.

Conclusion: The antibody titers detected in the backyard chickens suggested recent exposure to aMPV. Considering these results, further large-scale serological and molecular studies are needed to evaluate the prevalence of aMPV in these birds and characterize the circulating strains of aMPV in this region.

Keywords: antibodies, chickens, pigeons, Saudi Arabia.
Prototype for rapid test devices to detect residues of sulfonamides in chicken carcasses from traditional breeders in Surabaya, Indonesia
Authors: Lazuardi Mochamad , Hestianah Eka Pramyrtha , Restiadi Tjuk Imam
Published: June 2023

Background and Aim: Sulfadiazine, one of the sulfonamide group’s active compounds, is widely used for therapeutic production against several diseases. Veterinary drug residues can have a significant impact on human health conditions. This study aimed to develop a prototype of rapid test devices (RTDs) for detecting sulfadiazine residues on chicken carcasses based on the color indication.

Materials and Methods: Seven samples of carcasses collected from traditional breeders in Surabaya-Indonesia were prepared and tested using RTDs. This sample represents the population considering that in the last report, the use of antibiotics was more than 40%, while the ability to monitor RTDs was estimated at 100. The standard color of purple by Hex code standard color or decimal code color was used to compare the positive samples. A light-emitting diode (LED) lamp was used to observe purple color. Analysis of sulfonamides resulting from RTDs was compared using a ultraviolet-visible spectrophotometer.

Results: Sulfonamides contamination levels of 50% and 100% were detected at concentrations of 0.472 µg/mL and 0.642 µg/mL, respectively. Sulfonamides contamination that was <0.395 µg/mL did not appear purple.

Conclusion: The study’s findings showed that RTDs can be used to detect sulfonamides residues at a limit of detection 0.5 µg/mL after a 45 min exposure to an LED operating at a wavelength of 980 nm (p < 0.05). The limitation of RTDs was not being able to monitor the presence of residues bound in fat samples. Rapid test devices can be developed for commonly monitoring devices due to the limited technology available in the market.

Published: June 2023

Pancreatic ductal adenocarcinoma (PDAC) classically presents as a solitary mass on cross-sectional imaging. Diffuse-type PDAC is an unusual variant that accounts for 1%–5% of PDACs. Owing to its rarity, there are no established radiographic or endosonographic definitions. We report a unique case of diffuse-type PDAC presenting with imaging findings of 2 distinct masses in the pancreatic head and tail and with endoscopic ultrasound findings of diffuse gland enlargement mimicking autoimmune pancreatitis. The case illustrates the importance of sampling several areas of the pancreas when diffuse enlargement is present on endoscopic ultrasound and multiple masses are seen on cross-sectional imaging.

Published: June 2023

Cholestasis due to sepsis is commonly seen in critically ill patients; however, it is often overlooked and poses a challenge in clinical diagnosis and management. In this report, we present a 29-year-old woman who presented to the emergency department with jaundice and symptoms of a urinary tract infection. Initially suspected to be Dubin-Johnson syndrome, sepsis-induced cholestasis was eventually diagnosed after testing. Sepsis should always be considered as part of the differential diagnosis while managing a patient with jaundice. The management of sepsis-induced cholestasis involves treating the underlying infection. In most cases, liver injury improves with the resolution of the infectious process.

Published: June 2023

Metastatic lesions to the colon are far less common than primary tumors. Breast cancer metastasis to the colon is rarely reported, and it is often atypical in presentation and difficult to diagnose. We present a case of a diminutive asymptomatic breast cancer metastasis to the colon found during surveillance colonoscopy in a patient with long-lasting ulcerative colitis, which was initially regarded as a colitis-associated dysplastic lesion. Because early detection of metastatic disease plays a key role in the treatment of patients with breast cancer, a high index of suspicion must be maintained for atypical metastatic presentations to the gastrointestinal tract.

Published: June 2023

Aim. To analyze and determine the optimal indications for microsurgical operative interventions in the shortest possible time from the subarachnoid hemorrhage onset to prevent anterior communicating artery (AcomA) aneurysm re-rupture and bleeding.
Materials and methods. 280 patients with brain aneurysms were examined at the Uzhhorod Regional Center of Neurosurgery and Neurology and the City Hospital of Urgent and Emergency Medical Care under Zaporizhzhia City Council. Among them, 98 patients (48 males and 50 females) were diagnosed with AcomA aneurysms. The age of patients with AcomA aneurysms was from 20 to 72 years (mean age 47.8 ± 11.0 years). Aneurysms were verified using head and neck computed tomography angiography (a Toshiba Astelion scanner, 2016, No. 4СС162106), selective cerebral angiography (an angiography system General Energy Optima IGS 330, 2019, No. 80071260314), and brain magnetic resonance angiography (an i_Open 0,36 T magnetic resonance tomograph, 2005, No. Toc102633006). Cerebral hemodynamics was assessed using transcranial dopplerography (“Philips HD7” ultrasound diagnostic system, 2014, No. 69935).
Results. In the first three days after the onset of subarachnoid hemorrhage, 18 (18 %) patients were admitted with ruptured aneurysms of this location, 62 (62 %) within 4–8 days, 12 (12 %) patients within 9–14 days, later than 14 days – 6 (6 %). All 98 patients underwent microsurgical clipping of AcomA aneurysms. Due to severe cerebral edema, decompressive craniectomy was performed in two patients. The results of surgical treatment were evaluated according to the modified Rankin scale at the time of hospital discharge and were as follows: in 65 (65 %) patients – good; in 18 (18 %) – moderate disability; in 4 (4 %) – serious disability. 11 (11 %) patients died.
Conclusions. The treatment outcomes in patients with ruptured AcomA aneurysms were significantly dependent on factors related to increased risk of re-rupture: the presence of large-sized intracerebral hematoma, the aneurysm index exceeding 2, and multi-chamber aneurysm.

Published: June 2023

The aim – systematization of data from modern scientific sources and own knowledge and experience regarding the problems, advantages and prospects of the development of various methods of diagnosing pathological conditions of the cervix.
The relevance of the problem of cervical cancer is beyond doubt, which is confirmed by the annual data of the official statistics and recommendations of WHO, European experts and relevant national recommendations. The analysis and generalization of information from the specialized literature regarding the assessment of problems and prospects for the development of leading methods of cervical screening in order to reduce the number of cervical cancer cases in the world is a priority task of the expert society.
Currently, the most recommended approach to cervical screening is to combine HPV testing with cytology but separate testing for HPV is the most promising. Colposcopy remains the only confirmatory method of diagnosing cervical pathology, subject to mandatory cervical biopsy and histopathological examination of the biopsy. Standardization of classifications and terminology in the assessment of cytological, histopathological and colposcopic conclusions will allow to reach an understanding in the issues of optimal management tactics for patients with cervical pathology.
Conclusions. Diagnosis of high-risk carcinogenic types of human papillomavirus is the most promising method of cervical screening in the near future. At the same time, at the moment, we consider it appropriate to use the cytology together with HPV testing, at least as a sorting method. Standardization of cytological/histopathological terminology should be done in accordance with the Bethesda 2014 system update.

Conclusions. In the case of surgical interventions for complicated forms of colon cancer, lymphatic dissection in the minimum extent (D1) was performed in 54 (76.06 %) patients, and 17 (23.94 %) patients were operated on without removal of lymph nodes. The insufficient level of performing lymphatic dissections in patients with complicated forms of malignant pathology of the large intestine does not make it possible to assess the real picture of metastatic lesions of regional lymph nodes and to assign the correct stage of pN according to TNM 8 (in 17 (23.94 %) patients, no pathomorphological assessment was performed at all, and in 40 (56.34 %) patients, the number of examined lymph nodes were not indicated in the preparation). In the structure of staging of oncopathology, in 12 (16.90 %) patients, the stage of cancer was assign only according to the criterion of the degree of invasion (T) and in 5 (7.04 %) patients – only according to the data of instrumental examination and intraoperative revision (clinically), and was overestimated. Lack of a clear consistent assessment of the macroscopic, microscopic, immunohistochemical and molecular characteristics of the tumor process in 17 (23.94 %) patients leads to inaccuracies in the assessment of the stage of the tumor process, which in turn affects the prognosis for relapse and survival of the patient, and the tactic of postoperative treatment.

Distal biceps tendon rupture is most commonly found in working-age men, making the treatment terms and functional recovery level of significant socio-economic importance. Modern scientific research aims to minimize the number of complications, particularly recurrent ruptures. Attention is drawn to modern technologies aimed at stimulating regenerative processes, including the use of the stromal vascular fraction (SVF) of abdominal adipose tissue. The article presents the results of the practical application of SVF in the surgical restoration of the distal biceps tendon of the shoulder.
The aim of the study: to improve the results of surgical treatment of distal biceps tendon rupture, shorten recovery times and reduce the incidence of complications using stromal vascular fraction obtained from adipose tissue.
Materials and methods. The study was carried out by evaluating the results of surgical restoration of the distal biceps tendon in 34 patients who were divided into 2 groups – with intraoperative introduction of SVF at the reattachment site (n = 14) and without it (n = 20). At follow-up examinations after 3 days, 2 weeks, 6 weeks, and 3 months, the results of the patients were evaluated using the VASH, DASH scales and the range of motion in the affected elbow joint was measured. In addition, a general blood analysis and quantitative determination of C-reactive protein were performed before the operation and at follow-up visits.
Results. There was no difference in the level of C-reactive protein and the general blood analysis score between patients in both groups at all study time points. It was found that after 2 weeks, the VAS score was significantly lower in the study group. The DASH score on follow-up examinations after 2 and 6 weeks was significantly better in the study group. Also, at follow-up examinations after 2 and 6 weeks, a greater volume of supination movements was observed in the study group.
Conclusions. The using of SVF did not lead to the development of postoperative complications. The using of SVF allowed the reduction of the recovery time and decreased in the incidence of complications, as well as improved functional outcomes.

Nongenetic movement disorders are common throughout the world. The movement disorders encountered may vary depending on the prevalence of certain disorders across various geographical regions. In this paper, we review historical and more common nongenetic movement disorders in Asia. The underlying causes of these movement disorders are diverse and include, among others, nutritional deficiencies, toxic and metabolic causes, and cultural Latah syndrome, contributed by geographical, economic, and cultural differences across Asia. The industrial revolution in Japan and Korea has led to diseases related to environmental toxin poisoning, such as Minamata disease and β-fluoroethyl acetate-associated cerebellar degeneration, respectively, while religious dietary restriction in the Indian subcontinent has led to infantile tremor syndrome related to vitamin B12 deficiency. In this review, we identify the salient features and key contributing factors in the development of these disorders.

The miR-141-3p has been reported to participate in regulating autophagy and tumor-stroma interactions in ovarian cancer (OC). We aim to investigate whether miR-141-3p accelerates the progression of OC and its effect on macrophage 2 polarization by targeting the Kelch-like ECH-associated protein1-Nuclear factor E2-related factor2 (Keap1-Nrf2) pathway. SKOV3 and A2780 cells were transfected with miR-141-3p inhibitor and negative control to confirm the regulation of miR-141-3p on OC development. Moreover, the growth of tumors in xenograft nude mice treated by cells transfected with miR-141-3p inhibitor was established to further testify the role of miR-141-3p in OC. The expression of miR-141-3p was higher in OC tissue compared with non-cancerous tissue. Downregulation of miR-141-3p inhibited the proliferation, migration, and invasion of ovarian cells. Furthermore, miR-141-3p inhibition also suppressed M2-like macrophage polarization and in vivo OC progression. Inhibition of miR-141-3p significantly enhanced the expression of Keap1, the target gene of miR-141-3p, and thus downregulated Nrf2, while activation of Nrf2 reversed the reduction in M2 polarization by miR-141-3p inhibitor. Collectively, miR-141-3p contributes to tumor progression, migration, and M2 polarization of OC by activating the Keap1-Nrf2 pathway. Inhibition of miR-141-3p attenuates the malignant biological behavior of ovarian cells by inactivating the Keap1-Nrf2 pathway.

Twisting is an important part in the production process of large package E-glass yarn. To derive the twisting process parameters of large package E-glass yarn, a method from the physical properties of bobbin yarn is proposed based on the study of the twisting principle of E-glass yarn. After unwinding the bobbin yarn and measuring its twist, loop pitch, and corresponding diameter, the calculation is completed according to the steps of first determining the descending speed of the traveler, then fitting the spindle speed data, and finally calculating the elevating speed of the traveler. The result is that the twisting spindle speed of D450 E-glass yarn with 31.8 T/m decreases from 5,015 to 4,550 rpm, the elevating speed of the traveler is 0.91 m/min, and the descending speed of the traveler is 1.50 m/min. The accuracy of the calculation is verified by monitoring the rotating speed of the roving cake and measuring the loop pitch of bobbin yarn in the twisting experiment. The result shows that the prediction error of this method is less than 1.1%, which can effectively derive the twisting process parameters of large package E-glass yarn, and provide a reference for the twisting process design scheme of glass fiber strand manufacturers.

To Paul Meyer and Les Films de l’Églantine, Belgium

Paul Meyer, filmmaker and documentarist, born September 29, 1920, died September 29, 2007 in Belgium. He had his own production company Les films de l´églantine in his hometown Barchon, Belgium. Due to lucky circumstances, I met him during the French Film Festival, Tübingen, in 1995 and am still in possession of a personal hand-written letter from him, dated August, 1995. Our talk is documented in Blickpunkt: Film of 17th July, 1995.

Der Beitrag beschreibt am Beispiel von vier Dokumentarfilmen exemplarisch die Arbeit und das Werk von Luigi di Gianni, einem wichtigen Vertreter visueller Anthropologie in Europa, Schüler von Ernesto de Martino und Paul Meyer. Die Arbeiten zeigen therapeutische Riten süditalienischer Volksreligiosität aus der Zeit zwischen den fünfziger Jahren bis in die erste Dekade des 21. Jahrhunderts hinein und würdigen das Werk di Giannis in seiner bisher vernachlässigten Bedeutung für die Religionswissenschaft und die Europäische Religionsgeschichte.

Today, there are varieties of methods for determining the risk of flooding in different areas of a catchment. However, the use of GIS-based weighting is receiving increasing attention among researchers. In early 2019, severe and continuous floods occurred in some provinces of Iran. Khorramabad was one of the cities most affected by the floods. Regrettably, during the construction development of Khorramabad city, the minimum distance from roads was violated. In this study, flood risks in the area were zoned using a GIS-weighted overlay algorithm. Flood zoning was done based on various maps indicating factors such as rainfall, distance from the waterway, soil composition, waterway density, slope, soil permeability, land use, and vegetation. The flooding area then was parceled into six categories with return periods of 10, 30, and 50 years. As a result, the city was divided into three critical areas in terms of flood risk. The results indicate that the confluence of the Karganeh and Khorram–Rud rivers lacks sufficient capacity to withstand and repel floods. As a result, the city will suffer severe damage in future floods.

Vasospastic angina (VSA) occurs at rest and on exertion, with transient electrocardiographic ischemic changes. VSA presents with spontaneous coronary artery spasm (CAS); it has been associated with stable angina, acute coronary syndromes, and sudden cardiac death. CAS can be identified in normal arteries or non-obstructive coronary atherosclerosis, but is also prevalent in patients with coronary artery disease. The diagnosis is made with invasive coronary reactivity testing with provocation using acetylcholine (Ach). Epicardial spasms can be visualized through coronary angiography as a reversible epicardial vessel narrowing, while the diagnosis of microvascular spasm can be made when angina symptoms and ECG changes happen following intracoronary Ach without epicardial spasm. Identification of CAS allows for risk stratification and specific therapies targeting endothelial dysfunction and paradoxical vascular smooth muscle cell constriction. Therapies include calcium channel blockers as monotherapy or in a combination of a dihydropyridine and non-dihydropyridine. Short-acting nitrates offer acute symptomatic relief but long-acting nitrates should be used sparingly. This current update on invasive evaluation of VSA discusses unified Ach protocols.

A literatura recente sobre a categoria da agricultura familiar tem abordado os mais diversos processos de mudanças pelos quais a mesma vem sendo submetida ao longo dos anos. Este artigo busca auxiliar na compreensão de como está ocorrendo o processo de sucessão na agricultura familiar na região do Litoral Norte do Rio Grande do Sul, verificando a existência ou não de relação com o processo de ensino ofertado pelas escolas locais. Especificamente analisa-se o caso de uma possível relação do ensino médio politécnico com a agricultura familiar no município de Itati-RS. Nesse sentido, os resultados enfatizam que uma parcela significativa dos alunos, vinculados as escolas rurais, admite que a introdução de conteúdos voltados às temáticas da agricultura familiar e do desenvolvimento rural iria colaborar na formação das suas perspectivas de estudar, e posteriormente trabalhar vinculado a agricultura familiar, permanecendo assim no espaço rural.
