Fixed-Time Synchronization of Neural Networks Based on Quantized Intermittent Control for Image Protection
Authors: Yang Wenqiang , Xiao Li , Huang Junjian , Yang Jinyue
Published: November 2021

This paper considers the fixed-time synchronization (FIXTS) of neural networks (NNs) by using quantized intermittent control (QIC). Based on QIC, a fixed-time controller is designed to ensure that the NNs achieve synchronization in finite time. With this controller, the settling time can be estimated regardless of initial conditions. After ensuring that the system has stabilized through this strategy, it is suitable for image protection given the behavior of the system. Meanwhile, the encryption effect of the image depends on the encryption algorithm, and the quality of the decrypted image depends on the synchronization error of NNs. The numerical results show that the designed controller is effective and validate the practical application of FIXTS of NNs in image protection.

Published: November 2021

Background and Objectives: Since spontaneous uterine rupture in the mid-trimester is rare, maternal and fetal outcomes in subsequent pregnancies remain unclear. Therefore, this study aimed to examine the maternal and fetal outcomes of subsequent pregnancies after prior mid-trimester uterine rupture. Materials and Methods: A systematic review using PubMed, the Cochrane Central Register of Controlled Trials, and Scopus until 30 September 2021, was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The studies that clarified the maternal and fetal outcomes after prior mid-trimester uterine rupture and our case (n = 1) were included in the analysis. Results: Among the eligible cases, there were five women with eight subsequent pregnancies after prior mid-trimester uterine rupture. The timing of prior mid-trimester uterine rupture ranged from 15 to 26 weeks of gestation. The gestational age at delivery in subsequent pregnancies was 23–38 gestational weeks. Among the included cases (n = 8), those involving prior mid-trimester uterine rupture appeared to be associated with an increased prevalence of placenta accreta spectrum (PAS) (n = 3, 37.5%) compared with those involving term uterine rupture published in the literature; moreover, one case exhibited recurrent uterine rupture at 23 weeks of gestation (12.5%). No maternal deaths have been reported in subsequent pregnancies following prior mid-trimester uterine rupture. Fetal outcomes were feasible, except for one pregnancy with recurrent mid-trimester uterine rupture at 23 weeks of gestation, whose fetus was alive complicated by cerebral palsy. Conclusions: Our findings suggest that clinicians should be aware of the possibility of PAS and possible uterine rupture in pregnancies after prior mid-trimester uterine rupture. Further case studies are warranted to assess maternal and fetal outcomes in pregnancies following prior mid-trimester prior uterine rupture.

Published: November 2021

The COVID-19 pandemic is a new challenge for the diagnosis and treatment of infective endocarditis (IE). Fever and other unspecific symptoms of coronaviral infection could be misleading or masking its manifestations. We present the case of a young patient admitted for persistent fever, profuse sweating, headache, articular pain, myalgias, and weight loss. She reported regression taste and smell disorders compared to a month earlier when diagnosed with moderate COVID-19 pneumonia. While the RT-PCR SARS-COV-2 test was positive, she was admitted to a COVID-19 ward. Investigations of febrile syndrome revealed two positive blood cultures with Streptococcus gordonii and the presence of vegetations on the aortic valve, supporting a certain diagnosis of IE. After six weeks of antibiotic treatment, the patient had clinical and biologic favorable outcomes. Streptococcus gordonii is a common commensal related to the dental biofilm, although there were no caries in our patient. The influence of COVID-19 infection on the human microbiome by modifying the virulence of some commensal germs may be a risk factor for IE pathogenesis on native valves and requires the vigilance of clinicians for suspicion of this disease.

Published: November 2021

Walled-off pancreatic necrosis (WOPN) is one of the local complications of acute pancreatitis (AP). Several interventional techniques have been developed over the last few years. The purpose of this narrative review is to explore such methodologies, with specific focus on endoscopic drainage and direct endoscopic necrosectomy (DEN), through evaluation of their indications and timing for intervention. Findings indicated how, after the introduction of lumen-apposing metal stents (LAMS), DEN is becoming the favorite technique to treat WOPN, especially when large solid debris or infection are present. Additionally, DEN is associated with a lower adverse events rate and hospital stay, and with improved clinical outcome.

Published: November 2021

Background and Objectives: Ovarian cancer is the leading cause of death among gynecological tumors. PD-1/PD-L1 immunoregulatory mechanism is activated in ovarian cancers. Lymphocyte infiltration is a significant factor that affects its expression. We analyzed the correlation between localization of lymphocytic infiltrate and PD-L1 expression in epithelial ovarian tumors. Materials and Methods: PD-L1 expression was analyzed in 328 subjects, 122 with epithelial ovarian carcinoma, 42 with atypical proliferative tumor, and 164 with benign epithelial ovarian tumor. Expression in central and invasive tumor parts in epithelial ovarian carcinoma was combined with the most pronounced lymphocyte reaction. Immunohistochemical analysis was performed using the tissue microarray and correlated with a set of histopathology parameters. Results: PD-L1 expression was most prominent in epithelial ovarian carcinoma with different levels of expression observed between invasive and central tumor segments. A high level of PD-L1 expression on tumor cells was more frequently present in the invasive than in the central tumor parts (p < 0.001) only in high-grade serous ovarian carcinoma (HGSC). There was no significant correlation between peritumoral lymphocytic infiltrate and PD-L1 expression regardless of tumor segment. In the central tumor parts of HGSC, there was a correlation of intratumoral lymphocytic infiltrate with a higher level of PD-L1 expression (p = 0.003). Conclusions: The most prominent PD-L1 expression was observed in the invasive tumor parts of HGSC. Only the central parts of the HGSC exhibited significant PD-L1 expression in association with considerable intratumoral lymphocytic infiltrate.

Published: November 2021

Background and objectives: The course of SARS-CoV-2 (COVID-19) is still under analysis. The majority of complications arising from the infection are related to the respiratory system. The adverse effect of the viral infection on bone and joint tissue has also been observed. Materials and Methods: We present a group of 10 patients with degeneration of large joints and adjacent epiphyses of long bones and the spine, with a background of bone infarctions and avascular necrosis (AVN) immediately after infection with the COVID-19 virus. In MR imaging, changes in the characteristics of AVN were documented. Results: Observation of this group showed a clear correlation among the history of COVID-19 disease in the patients, moderately severe symptoms, high levels of IgG antibodies, and the time of occurrence of joint changes. No other clinically significant complications were observed following COVID-19 infection in the study group. No other risk factors for AVN or autoimmune or degenerative diseases were found in the study group. The group of patients responded well to empirical treatment with steroids, which normalized acute inflammatory symptoms and pain in the joints. Conclusions: During coronavirus (COVID-19) infection, there are complications in the locomotor system, such as microembolism and the formation of AVN; hence, more research is needed.
A Brief Introduction to Some Aspects of the Fluid–Mosaic Model of Cell Membrane Structure and Its Importance in Membrane Lipid Replacement
Authors: Nicolson Garth L. , Ferreira de Mattos Gonzalo
Published: November 2021

Early cell membrane models placed most proteins external to lipid bilayers in trimolecular structures or as modular lipoprotein units. These thermodynamically untenable structures did not allow lipid lateral movements independent of membrane proteins. The Fluid–Mosaic Membrane Model accounted for these and other properties, such as membrane asymmetry, variable lateral mobilities of membrane components and their associations with dynamic complexes. Integral membrane proteins can transform into globular structures that are intercalated to various degrees into a heterogeneous lipid bilayer matrix. This simplified version of cell membrane structure was never proposed as the ultimate biomembrane description, but it provided a basic nanometer scale framework for membrane organization. Subsequently, the structures associated with membranes were considered, including peripheral membrane proteins, and cytoskeletal and extracellular matrix components that restricted lateral mobility. In addition, lipid–lipid and lipid–protein membrane domains, essential for cellular signaling, were proposed and eventually discovered. The presence of specialized membrane domains significantly reduced the extent of the fluid lipid matrix, so membranes have become more mosaic with some fluid areas over time. However, the fluid regions of membranes are very important in lipid transport and exchange. Various lipid globules, droplets, vesicles and other membranes can fuse to incorporate new lipids or expel damaged lipids from membranes, or they can be internalized in endosomes that eventually fuse with other internal vesicles and membranes. They can also be externalized in a reverse process and released as extracellular vesicles and exosomes. In this Special Issue, the use of membrane phospholipids to modify cellular membranes in order to modulate clinically relevant host properties is considered.
A Review of the Commercially Available ECG Detection and Transmission Systems—The Fuzzy Logic Approach in the Prevention of Sudden Cardiac Arrest
Authors: Lewandowski Michał
Published: November 2021

Sudden cardiac death (SCD) constitutes a major clinical and public health problem, whose death burden is comparable to the current worldwide pandemic. This comprehensive review encompasses the following topics: available rescue systems, wearable electrocardiograms (ECG), detection and transmission technology, and a newly developed fuzzy logic algorithm (FA) for heart rhythm classification which is state-of-the art in the field of SCD prevention. Project “PROTECTOR”, the Polish Rapid Transtelephonic ECG to Obtain Resuscitation for development of a rapid rescue system for patients at risk of sudden cardiac arrest (SCA), is presented. If a lethal arrhythmia is detected on the basis of FA, the system produces an alarm signal audible for bystanders and transmits the alarm message along with location to the emergency medical center. Phone guided resuscitation can be started immediately because an automated external defibrillator (AED) localization map is available. An automatic, very fast diagnosis is a unique feature of the PROTECTOR prototype. The rapid detection of SCA is based on a processor characterized by 100% sensitivity and 97.8% specificity (as measured in the pilot studies). An integrated circuit which implements FA has already been designed and a diagnosis is made within few seconds, which is extremely important in ischemic brain damage prophylaxis. This circuit could be implemented in smart implants (Sis).

Members of the genus Borrelia are arthropod-borne spirochetes that are human and animal pathogens. Vertebrate hosts, including wild animals, are pivotal to the circulation and maintenance of Borrelia spirochetes. However, information on Borrelia spirochetes in vertebrate hosts in Zambia is limited. Thus, we aimed to investigate the presence of Borrelia spirochetes in wild animals and cattle in Zambia. A total of 140 wild animals of four species and 488 cattle DNA samples from /near the Kafue National Park were collected for real-time PCR screening, followed by characterization using three different genes with positive samples. Five impalas and 20 cattle tested positive using real-time PCR, and sequence analysis revealed that the detected Borrelia were identified to be Borrelia theileri, a causative agent of bovine borreliosis. This is the first evidence of Borrelia theileri in African wildlife and cattle in Zambia. Our results suggest that clinical differentiation between bovine borreliosis and other bovine diseases endemic in Zambia is required for better treatment and control measures. As this study only included wild and domestic animals in the Kafue ecosystem, further investigations in other areas and with more wildlife and livestock species are needed to clarify a comprehensive epidemiological status of Borrelia theileri in Zambia.

Published: November 2021

Respiratory pathogens are a health threat for poultry. Co-infections lead to the exacerbation of clinical symptoms and lesions. Mycoplasma gallisepticum (M. gallispeticum) and Avian Metapneumovirus (AMPV) are two avian respiratory pathogens that co-circulate worldwide. The knowledge about the host–pathogen interaction of M. gallispeticum and AMPV in the chicken respiratory tract is limited. We aimed to investigate how co-infections affect the pathogenesis of the respiratory disease and whether the order of invading pathogens leads to changes in host–pathogen interaction. We used chicken tracheal organ cultures (TOC) to investigate pathogen invasion and replication, lesion development, and selected innate immune responses, such as interferon (IFN) α, inducible nitric oxide synthase (iNOS) and IFNλ mRNA expression levels. We performed mono-inoculations (AMPV or M. gallispeticum) or dual-inoculations in two orders with a 24-h interval between the first and second pathogen. Dual-inoculations compared to mono-inoculations resulted in more severe host reactions. Pre-infection with AMPV followed by M. gallispeticum resulted in prolonged viral replication, more significant innate immune responses, and lesions (p < 0.05). AMPV as the secondary pathogen impaired the bacterial attachment process. Consequently, the M. gallispeticum replication was delayed, the innate immune response was less pronounced, and lesions appeared later. Our results suggest a competing process in co-infections and offer new insights in disease processes.

Published: November 2021

Reports on the use of 16S sequencing for the identification of bacteria in healthy animals are lacking. Bacterial contamination of bull semen can have a negative effect on the sperm quality. The aims of this study were threefold: to identify bacteria in the semen of healthy bulls using 16S sequencing; to investigate the differences in the bacterial community between individual bulls; and to establish if there was a relationship between the bacteria isolated and bull fertility. Semen from 18 bulls of known fertility was used for the DNA extraction and 16S sequencing; 107 bacterial genera were identified. The differences in the amplicon sequence variants (ASVs) and the numbers of genera between bulls were noted. Negative correlations (p < 0.05) between several bacterial genera with Curvibacter, Rikenellaceae RC9-gut-group and Dyella spp. were seen. Other negatively correlated bacteria were Cutibacterium, Ruminococcaceae UCG-005, Ruminococcaceae UCG-010 and Staphylococcus, all within the top 20 genera. Two genera, W5053 and Lawsonella, were enriched in bulls of low fertility; this is the first time that these bacteria have been reported in bull semen samples. The majority of the bacteria were environmental organisms or were species originating from the mucous membranes of animals and humans. The results of this study indicate that differences in the seminal microbiota of healthy bulls occur and might be correlated with fertility.
Immunostimulatory Activity of Synbiotics Using Lactococcus lactis SG-030 and Glucooligosaccharides from Weissella cibaria YRK005
Authors: Kwon Ayeon , Park Young-Seo
Published: November 2021

Much attention has been recently paid to the health benefits of synbiotics, a combination of probiotics and prebiotics. In this study, synbiotics were prepared by combining lactic acid bacteria with potential as probiotics and purified glucooligosaccharides, and their immunostimulatory activity was evaluated using RAW 264.7 macrophage cells. A lactic acid bacteria strain with high antioxidant activity, acid and bile salt tolerance, adhesion to Caco-2 cells, and nitric oxide (NO) production was selected as a potential probiotic strain. The selected strain, isolated from forsythia, was identified as Lactococcus lactis SG-030. The purified glucooligosaccharides produced from Weissella cibaria YRK005 were used as prebiotics. RAW 264.7 cells were treated with synbiotics in two ways. One way was a simultaneous treatment with lactic acid bacteria and glucooligosaccharides. The other way was to pre-culture the lactic acid bacteria with glucooligosaccharides followed by treatment with synbiotic culture broth or synbiotic culture supernatant. In both cases, synbiotics synergistically increased NO production in RAW 264.7 cells. In addition, synbiotics treatment increased the expression of tissue necrosis factor-α, interleukin (IL)-1β, IL-6, and inducible nitric oxide synthase genes. Synbiotics also increased the expression of P38, extracellular signal-regulated kinases, c-Jun N-terminal kinases, phosphoinositide 3-kinase, and Akt proteins. The results confirmed that the synbiotics prepared in this study exhibited synergistic immunostimulatory activity.
Effects of Vertical Spatial Overlap on Phytoplankton Diversity under Experimentally Altered Lake Stratification Regimes
Authors: Le Noac’h Philippe , Ouellet Jobin Vincent , Beisner Beatrix E.
Published: November 2021

In phytoplankton communities, competitive exclusion might occur when functionally similar species are impeded from regulating their positions along light and nutrient gradients to reduce niche overlap. Greater spatial overlap (SO) between species due to water column mixing could thus promote competitive exclusion, reducing community taxonomic diversity. However, greater SO could also promote coexistence of functionally different taxa. Using data from a whole-lake experiment, we investigated the effects of SO and other relevant environmental factors on phytoplankton diversity across the water columns of lake basins with different thermocline manipulations. We estimated SO using an in situ fluorometer, and overall community diversity microscopically. Using structured equation models, we estimated directional relationships between phytoplankton diversity, SO, the lake physical structure and the zooplankton community. No significant effect of SO on phytoplankton taxonomic diversity was observed, but higher SO was associated with greater functional diversity. Change in lake physical structure and in the zooplankton community also affected diversity, with a negative response to increased top-down interactions. Overall, despite the fact that the alteration of water column stratification structure and top-down interactions were stronger drivers of phytoplankton diversity in our system, some effect of spatial overlap on the outcome of inferred competitive interactions were observable.
From Lab to Farm: Elucidating the Beneficial Roles of Photosynthetic Bacteria in Sustainable Agriculture

Published: November 2021

Photosynthetic bacteria (PSB) possess versatile metabolic abilities and are widely applied in environmental bioremediation, bioenergy production and agriculture. In this review, we summarize examples of purple non-sulfur bacteria (PNSB) through biofertilization, biostimulation and biocontrol mechanisms to promote plant growth. They include improvement of nutrient acquisition, production of phytohormones, induction of immune system responses, interaction with resident microbial community. It has also been reported that PNSB can produce an endogenous 5-aminolevulinic acid (5-ALA) to alleviate abiotic stress in plants. Under biotic stress, these bacteria can trigger induced systemic resistance (ISR) of plants against pathogens. The nutrient elements in soil are significantly increased by PNSB inoculation, thus improving fertility. We share experiences of researching and developing an elite PNSB inoculant (Rhodopseudomonas palustris PS3), including strategies for screening and verifying beneficial bacteria as well as the establishment of optimal fermentation and formulation processes for commercialization. The effectiveness of PS3 inoculants for various crops under field conditions, including conventional and organic farming, is presented. We also discuss the underlying plant growth-promoting mechanisms of this bacterium from both microbial and plant viewpoints. This review improves our understanding of the application of PNSB in sustainable crop production and could inspire the development of diverse inoculants to overcome the changes in agricultural environments created by climate change.
Susceptibility of Fluconazole-Resistant Candida albicans to Thyme Essential Oil
Authors: Alshaikh Najla A , Perveen Kahkashan
Published: November 2021

Candida spp. is the most common microbial pathogen in fungal infections. There has been a tremendous increase in cases of candidiasis, especially among critically ill non-neutropenic patients. Candida albicans’ isolates were procured from the Prince Sultan Military Hospital, Riyadh, KSA. The isolates were characterized for their identification using CHROMagar, carbohydrate metabolism, germ tube formation, and RAPD-PCR techniques. The essential oil of Thymus vulgaris was obtained by hydro-distillation and characterized to decipher the major bioactive phytoconstituents. The antifungal activity of the thyme essential oil (TEO) was evaluated against fluconazole-resistant C. albicans isolates. The major phytocomponents identified by GC/MS were thymol (68.1%) followed by γ-terpinene (8.9%), cymol (7.7%), caryophyllene (1.1%), linalool (1.4%). The TEO successfully reduced the growth of C. albicans isolates. At very low doses, the TEO proved to be fungi static and fungicidal. TEO also effectively inhibited the germ tube formation and budging of fungal pathogens. The time kill assays have shown that TEO was more effective against drug resistant clinical isolates than fluconazole. This study provides an array of experimental evidence regarding the therapeutic efficacy of TEO against the drug-resistant clinical isolates of C. albicans. The findings may be used in the development of a new antifungal agent accordingly.

Published: November 2021

Rhizobium leguminosarum (Rl) is a common name for several genospecies of rhizobia able to form nitrogen-fixing nodules on the roots of pea (Pisum sativum L.) while undergoing terminal differentiation into a symbiotic form called bacteroids. In this work, we used Oxford Nanopore sequencing to analyze the genome methylation states of the free-living and differentiated forms of the Rl strain RCAM1026. The complete genome was assembled; no significant genome rearrangements between the cell forms were observed, but the relative abundances of replicons were different. GANTC, GGCGCC, and GATC methylated motifs were found in the genome, along with genes encoding methyltransferases with matching predicted target motifs. The GGCGCC motif was completely methylated in both states, with two restriction–modification clusters on different replicons enforcing this specific pattern of methylation. Methylation patterns for the GANTC and GATC motifs differed significantly depending on the cell state, which indicates their possible connection to the regulation of symbiotic differentiation. Further investigation into the differences of methylation patterns in the bacterial genomes coupled with gene expression analysis is needed to elucidate the function of bacterial epigenetic regulation in nitrogen-fixing symbiosis.

Published: November 2021

To in situ and noninvasively monitor the biofilm development process by low-field nuclear magnetic resonance (NMR), experiments should be made to determine the mechanisms responsible for the T2 signals of biofilm growth. In this paper, biofilms were cultivated in both fluid media and saturated porous media. T2 relaxation for each sample was measured to investigate the contribution of the related processes to T2 relaxation signals. In addition, OD values of bacterial cell suspensions were measured to provide the relative number of bacterial cells. We also obtained SEM photos of the biofilms after vacuum freeze-drying the pure sand and the sand with biofilm formation to confirm the space within the biofilm matrix and identify the existence of biofilm formation. The T2 relaxation distribution is strongly dependent on the density of the bacterial cells suspended in the fluid and the stage of biofilm development. The peak time and the peak percentage can be used as indicators of the biofilm growth states.
The Alkaline Fusion-Hydrothermal Synthesis of Blast Furnace Slag-Based Zeolite (BFSZ): Effect of Crystallization Time
Authors: Li Changxin , Li Xiang , Zhang Qingwu , Li Li , Wang Shuai
Published: November 2021

Blast furnace slag (BFS) is usually regarded as a by-product of the steel industry, which can be utilized as raw material for preparing BFS-based zeolite (BFSZ). In this study, BFSZ was successfully prepared from BFS using alkaline fusion-hydrothermal synthesis. Via the analyses by XRD, SEM, EDX, XRF, FT-IR, elemental mapping and BET/BJH methods, BFSZ crystallization was almost complete at 6 h. With a further increase of crystallization time to 8 h, no significant effect on the formation of crystalline phase was found. Meanwhile, the zeolite content Si/Al (Na/Al) molar ratio was highly affected by crystallization time. The main component of BFSZ prepared at 6 h is cubic crystal with developed surface, with particle size around 2 μm. Moreover, further increasing the crystallization time will not significantly influence the size and morphology of BFSZ product.

Published: November 2021

The article presents an analysis of the prospects for the development of aquaculture in the southern regions of Russia. It is shown that the volume of aquaculture in the southern regions of the country in 2020 amounted to more than 78.6 thousand tons, which is 24% of the all-Russian. The Southern Federal District is one of the three leaders in the production of aquaculture products, its volume amounted to 81.4 thousand tons in 2019 and 70.2 thousand tons in 2020. About 90.6% of aquaculture products were received in the Rostov and Astrakhan regions, Krasnodar Krai. The volume of commercial production in the Republic of Crimea has increased significantly (by 23%). Pasture aquaculture, pond and industrial fish farming, recreational aquaculture, and mariculture are promising areas in the federal District. There is a great variety of growing objects, these are both traditional species for the region and the country — carp, herbivorous, sturgeon, and pike, common and channel catfish, walleye, perch, pilengas, paddlefish, buffalo. In addition, shellfish farms are actively developing on the coast of Crimea. The prospects of interaction between fundamental, branch, university science and enterprises of the real sector of the economy are shown. In order to achieve sustainable development of the country’s aquaculture, it is necessary to strengthen state support measures, especially for small businesses and fish farming. At the same time, support should be provided not only at the state, but also at the regional level.
Changes in morphological and physiological parameters of adult marsh frogs at different phases of their feeding and breeding technology
Authors: Zhelankin Roman Viktorovich
Published: November 2021

The article discusses the possibility of keeping a marsh frog in a farm on the territory of central Russia to obtain delicious meat. For this, at different stages of keeping and after spawning, body weight and length, as well as hematological parameters, were studied. During the study, marsh frogs were kept in different conditions, depending on the season of the year, and fed on different foods. During the summer and early autumn, when kept in a summer enclosure in the air temperature range from 15 to 23 °C, when fed with natural food (live invertebrates) and fed with cultivated cockroaches and flour beetle, a positive increase and an increase in weight was observed. Hematological indices were slightly below the conditional norm, but the number of segmented neutrophils and eosinophils in frogs in the aviary turned out to be quite high, since the natural food they consumed could activate antiparasitic immunity. When the frogs were kept in an aquarium at an air temperature of 22 °C and fed only with cultivated food, the distribution of weight gain and plumb weight was approximately equal. After hibernation at 4 °C, the frogs lost a lot of weight and were placed in a special spawning pool. After hormonal stimulation of frogs with a mixture of drugs “chorionic gonadotropin” and “surfagon”, successful spawning was observed with 100% fertilization of eggs, while the plumb line was small and more uniform. A low number of red blood cells and a low hemoglobin were found in the blood. The total number of neutrophils in frogs kept in the pool decreased, and the number of monocytes increased by 3 times, exceeding the conditional norm by half, which may indicate a monocytic-macrophage reaction necessary for the resorption of remnants of reproductive products. There was also a rapid development of a conditioned reflex in frogs to feeding on a floating feeder, which is an important link in the mechanization of frog farms.

The paper presents the results of analysis of electrical measurements performed in the space experiment "Impulse (stage 1)" on the Service module of the ISS RS. This experiment investigated the effects of the interaction of the charged component of the ionosphere to the surface of large KA, which is the ISS. This paper analyses the measurement of quasi-stationary electric field and current leakage, was, respectively, sensors of the vibration type and flat probes from the Complex control electrophysical parameters (CCEP), developed by SPJ MT. To study the dependence of measurements from the ionosphere flow direction to the surface of the ISS RS was installed two sets of sensors with the direction of the angle of "visibility" in the Nadir (towards the Earth) and to "satellite footprint " (against the velocity vector of the ISS).
Carried out analysis of common regularities measurements depending on the sun-shadow environment on orbit ISS motions and depending on current geophysical dynamics of the ionosphere. Massive the measurements including more than 170 telemetric sessions were analyzed. More than 11000 hours of measurements current of leakage (or runoff current) and measurements of quasi-stationary electric field with discretization 1s and UT binding to each point were analysed. The data measurements, geophysical and orbital data were collected in an electronic album.
It is shown that experimental data correlate with the crossing time of the ISS boundaries known geophysical structures: the noon Meridian, the Main ionospheric failure (MIF), the boundaries diffuse intrusion (BDI), the Equatorial Geomagnetic anomaly (EA). In this regard, despite the specificity of the ISS (the spacecraft super big sizes, the most complex spatial configuration) similar measurements, nevertheless, are quite suitable for monitoring researches of some features of an ionosphere at the level of F2 layer with a temporary scale from 1s and can be used for more detailed study of the geophysical structures and related effects in the ionosphere. In addition, the results obtained can be used for the analysis of disturbances of electromagnetic conditions near the surface of the ISS RS, for monitoring potential and currents of leakage on the surface of the ISS.

Economists expect that CPTPP, together with the EU-Vietnam Free Trade Agreement (FTA), will bring enormous economic benefits to Vietnam, by increasing the price competitiveness of Vietnam’s exports in key markets and boosting foreign direct investment (FDI), promoting economic development and creating millions of jobs, including in small and medium-sized enterprises. More importantly, CPTPP will help facilitate domestic reforms in many areas and build an environment for a competitive economy. The purpose of this article is to clarify the impact of free trade agreements on Vietnamese trade unions, which are considered exclusive in representing workers throughout the territory of Viet Nam but will no longer play this role when Viet Nam joins next-generation trade agreements.

SMK Al-Muawanah merupakan salah satu Sekolah Menengah Kejuruan yang ada di Kecamatan Tanjungjaya, Kabupaten Tasikmalaya. Berdasarkan investigasi yang dilakukan, manajemen aset di sekolah tersebut hanya mencatat data aset baru, sehingga kondisi aset lama menjadi tidak terpantau. Selain itu, pencatatan aset dilakukan dengan menyalin data beberapa kali. Selain tidak efisien, cara tersebut menyebabkan peluang kesalahan dalam memasukkan data aset semakin tinggi. Pemilihan metode dilakukan berdasarkan kondisi saat penelitian, yaitu belum adanya sistem informasi manajemen aset di SMK Al-Muawanah Tasikmalaya. Karena itu, dipilihlah metode waterfall, dengan pertimbangan bahwa tahapannya berurutan, sehingga lebih mudah untuk diterapkan. Dengan adanya perancangan sistem informasi manajemen aset ini, diharapkan dapat menjadi langkah awal dalam melakukan perbaikan manajemen aset di SMK Al-Muawanah.

Audit energy merupakan salah satu metoda yang diwajibkan oleh pemerintah RI dalam peningkatan program konservasi energy diindustri sekaligus sebagai peningkatan produksi atau pengurangan biaya konsumsi energi produksi. Program ini dikenal dikenal dengan nama Proper yang dikelola oleh kementrian lingkungan hidup dan kehutanan.  PT Geodipa Energi sebagai pemilik Pembangkit Listrik Tenaga Panas Bumi Patuha yang berkapasitas 60 MW (100%) berusaha mengikuti program ini yang bila lolos akan mendapatkan manfaat berupa insentif. Pengoptimalan kinerja pendinginan baik dikondenser dan cooling tower dengan beberapa parameter yang direkam di DCS digunakan sebaga data input meningkatkan vakum di luaran turbin. Vakum yang dihasilkan akan memperbesar torsi yang dihasilkan sehingga generator terrotasi lebih kuat dan output daya yang dihasilkan meneningkat. Penggunaan artificial intellegence (AI) dalam hal ini ANFIS (Adaptive Neuro Fuzzy Inference System) dikombinasikan dengan pengetahuan praktis teknologi proses kimia dapat memperkirakan optimasi yang akan dicapai. Torsi tambahan ini lebih lanjut diharapkan meningkatkan produksi energi listrik sampai 2 – 3 % dari rata rata 88% kapasits sekarang, tanpa menambah daya pemakaian sendiri (own used power).

To prevent the consument littering the waste cooking oil, we can recycle it to be biofuel with many fraction such as biodiesel, biogasoline, and biokerosene. There are many ways to process the waste cooking oil to be, biofuel one of them is catalytic cracking. This study is induct by observe the biofuel that form from the catalytic cracking process with cooking oil as the base material using a hybrid catalyst ZSM-5/Alumina. The purpose of this study is to observe the influence of ZSM-5 and Alumina ratio as heterogenic catalyst and also the used of the catalyst frequently. The highest conversion of liquid product was produce with value 41,67%  at alumina variation of 17,5%. The used of catalyst frequently will affect the decrease amount of liquid product that produce. The analysis of chemical properties using GC-MS obtained the amount of kerosene 29,917 %; gasoline 3,996 %; and diesel 10,1 %. The other product was carboxylics acids,alcohol, and unidentified compound.

Published: November 2021

The clinical phenomenology of post-stress disorders was studied in combatants. We observed 150 servicemen of the Armed Forces of Ukraine, who took a direct part in the fighting in the ATO zone, in accordance with the principles of bioethics and deontology on the basis of the National Military Medical Clinical Center «Main Military Clinical Hospital» and the Military Medical Center of the Northern Region.

It is shown, that the clinical structure of post-stress disorders in combatants is represented by posttraumatic stress disorder (PTSD), acute stress response and adjustment disorders. The clinical structure of PTSD in combatants is represented by anxious (35.2 % of men and 44.2 % of women), dysphoric (33.5 % and 9.4 %), asthenic (25.4 % and 32.6 %) and somatoform (5.9 % and 13.8 %) syndrome complexes. Adjustment disorders included prolonged depressive reaction (10.1 % of men and 15.7 % of women), mixed anxiety-depressive reaction (16.5 % and 10.2 %), adjustment disorders with a predominance of disturbances of other emotions (9.8 % and 7.4 %). The major risk factors for the development of stress-related disorders in combatants were identified: prolonged participation in combat, the need to see and touch the bodies of the dead, the threat of death from sniper’s fire, the death of friends in their own eyes, the impact of harmful combat factors, family conflicts, adverse social and economic circumstances.

The correlation analysis was carried out. It was found, that the severity of psychopathological symptoms is determined by the severity of combat mental trauma. High scores on the Mississippi scale are associated with prolonged mental trauma (rxy=0.64), threat of death (rxy=0.58), death of comrades (rxy=0.54), participation in close combat (rxy=0.50), the offensive (rxy=0.41), the need to touch the bodies of the dead (rxy=0.46), with the killing of opponents (rxy=0.45). There is a strong correlation of combat mental trauma with anxiety intensity (rxy=0.78), fear (rxy=0.71), sense of internal tension (rxy=0.70), disturbance of the sleep-wake cycle (rxy=0.70), incontinence of affect (rxy=0.69) and depression (rxy=0.66).

A comprehensive approach that includes the treatment of background and precancerous diseases of the vulva by photodynamic therapy and plasma therapy as rehabilitation therapy was developed. The method’s effectiveness was evaluated. The study is also aimed at evaluating the effectiveness of plasma therapy after treatment of background and precancerous diseases of the vulva by photodynamic therapy. The work is based on the study results of 60 patients aged 32 to 70 years old, mean age was (53.3+3.6) years, with a morphologically verified diagnosis of vulvar intraepithelial neoplasia, mixed vulvar dystrophy (Lichen sclerosus et atrophicus, squamous cell hyperplasia), which were divided into two groups. Patients of both groups underwent photodynamic therapy using an intravenous photosensitizer «Fotolon®» (RUE «Belmedpreparaty», Republic of Belarus), which is a complex of chlorine ебс trisodium salt with low molecular weight polyvinylpyrrolidone. The session of photodynamic therapy was performed 3^1 hours after the end of the FS infusion using a universal laser coagulator «Likar-Hirurg (Surgeon)» («Photonica Plus», Ukraine, A-660 nm). Plasma therapy was performed for patients of group 2 after photodynamic therapy. It has been established that the use of photodynamic therapy and plasma therapy increases the effect of treatment of background and precancerous diseases of the vulva, accelerates the period of damaged tissues regeneration and rehabilitation of patients twice and prolongs the recurrence-free period of the disease.

Afetlerde Sosyal Medya Kullanımı ve Etik İkilemler: İzmir Seferihisar Depremi Örneği
Authors: USTA Ertuğrul , YÜKSELER Mustafa
Published: November 2021

21. yüzyılda afetlerin sayısındaki artışlar, bütünleşik afet yönetimini ve disiplinlerarası çalışmaları gerektirmektedir. Bu disiplinlerden biri olan medyanın farkındalık oluşturma ve bilgi paylaşımı gibi yükümlülükleri bulunmaktadır. Son yüzyıl itibariyle web teknolojilerindeki gelişmeler, geleneksel medyadan farklı olanaklar sunan sosyal medyayı ortaya çıkarmıştır. Sosyal medyanın interaktif yapısı ve kamuoyuyla etkileşimi, dayanışma ve yardımlaşma ortamları sağlaması gibi afetlerdeki olumlu etkileriyle birlikte etik problemlere yol açabilen olumsuz etkileri de olabilmektedir. Çalışmamızda, 30 Ekim 2020 tarihinde İzmir Seferihisar açıklarında meydana gelen deprem sonrası, sosyal medya platformlarında yapılan paylaşımlar ve haber içerikleri, medya ve etik konularında düzenlenen ulusal ve uluslararası metinler baz alınarak değerlendirilmiştir. Yapılan değerlendirme sonucunda, afet ve acil durumlar sonrasında geleneksel ve sosyal medya paylaşım ve haber içeriklerinin hukuksal boyutta özel hayatın gizliliği, kişisel verilerin korunması gibi kişisel hakların yanında, etik boyutta haber öznesinin hassas durumu göz ardı edilerek oluşturulabildiği, herhangi bir süzgeçten geçmeden yayılarak afetin yönetimini zorlaştırabildiği görülmektedir. Bu sebeple, afet müdahale planlamaları içerisinde bu alana yönelik afet medya yönetimi planı oluşturulması, afet ve acil durumlarda medya kullanımına özgü rehber ilke ve kılavuzlar geliştirilmesi, halkın kriz durumlarında medya araçları kullanımı konusundaki farkındalık seviyesinin geliştirilmesi, mevzuat altyapısının hazırlanması gibi düzenleyici hazırlıkların yapılması gerekmektedir.
