To reduce the risk of infection of SARS-CoV-2 during the commute to the clinic or due to the contact with medical staff, The American College of Obstetricians and Gynecologists recommended ar-ranging part of the appointments in the form of “telehealth”. The aim of the study was to assess the access to medical care in pregnancy during the Sars-Cov-2 pandemic and the role of telehealth in implementation of prenatal care standards. This is a cross-sectional study. The study group in-cluded 618 women that were pregnant and or gave birth during the COVID-19 pandemic in Poland. The majority of participants experienced difficulties in access to medical care because of the pandemic. Correlation between this experience and the use of hybrid healthcare model was es-tablished. However, affiliation to public or private healthcare group was irrelevant. There was no relationship between healthcare (private/public or in-person/hybrid) and implementation of the prenatal care standards. To ensure safe access to prenatal care for pregnant women, recommen-dations for a hybrid pregnancy management model should be created with detailed information for which appointments patients must be present and which can be done remotely. To reduce movement risk and interpersonal contact, all visits during which tests and screenings take place should be done in-person. Other appointments can be arranged in the form of telehealth
Cellular Prion Protein and Amyloid – β Oligomers in Alzheimer's Disease – There Are Connections?
Authors: Hachiya Naomi , Fułek Michał , Zajączkowska Katarzyna , Kurpas Donata , Trypka Elżbieta , Leszek Jerzy
Published: May 2021

Alzheimer’s disease (AD) is the most common cause of dementia worldwide. Pathological deposits of neurotoxin proteins within the brain, such as amyloid-Beta and hyperphosphorylated tau tangles, are prominent features in AD. The prion protein (PrP) is involved in neurodegeneration via its conversion from the normal cellular form PrPc, to the infection form PrP Sc. Some studies indicated that posttranslationally modified PrPc isoforms plays a fundamental role in AD pathological progression. Several studies have shown that interaction of Aβ oligomers with N-terminal residues of the PrPc protein region appears critical for neuronal toxicity. The PrPc-Aβ binding always occur in AD brains and is never detected in nondemented controls and the binding of Aβ aggregates to PrPc is restricted to the N-terminus of PrPc.

Published: May 2021

(1) Background: Stimulating oropharyngeal transient receptor potential (TRP) channels inhibits muscle cramping by triggering a supraspinal reflex to reduce α-motor neuron hyperexcitability. This study investigated whether longer stimulation of TRP channels via mouth rinsing with PJ is more effective than drinking PJ at inhibiting an electrically induced muscle cramp (EIMC); (2) Methods: Tibial nerve in 11 cramp-prone adults were percutaneously stimulated to elicit an EIMC of flexor hallucis brevis in three trials 1-week apart. At cramp onset participants received mouth rinsing and expelling PJ (25 mL), ingesting PJ (1 mL∙kg-1 body-mass [BM]), or ingesting water (1 mL∙kg-1 BM). Cramp onset and offset by electromyography and severity of discomfort was recorded using a visual analogue scale (VAS); (3) Results: Median time to cramp cessation as a percentage of water was 82.8% ± 14.634 and 68.6% ± 47.782 for PJ ingestion and mouth rinse respectively. These results had large variability and no statistically significant difference was observed. There were also no differences in perceived cramp discomfort between conditions, despite hazard ratios for time to VAS = 0 higher than water for PJ ingestion (22%) and mouth rinse (35%) (p = 0.66 and 0.51 respectively); (4) Conclusions: Data suggest no difference in cramp duration and perceived discomfort between PJ and water.
A Wavelet-Based Method for the Impact of Social Media on the Economic Situation: The Saudi Arabia 2030-Vision Case
Authors: Balalaa Majed Salah S. , Ben Mabrouk ANOUAR , Abdessalem Habiba
Published: May 2021

In the present paper, we propose a wavelet method to study the impact of electronic media on economic situations. We precisely apply wavelet techniques versus classical methods to analyze economic indices in the market. The technique consists firstly in filtering the data from unprecise circumstances (noise) to construct next a wavelet denoised contingency table. Next, a thresholding procedure is applied to such a table to extract the essential information porters. The resulting tables subject finally to correspondence analysis before and after thresholding. As a case of study, we are empirically concerned with the 2030 KSA vision in electronic and social media. Effects of the electronic media texts about the trading 2030 Vision on the Saudi and global economy have been studied. Recall that the Saudi market is the most important representative market in the GCC continent. It has both regional and worldwide influence on economies and besides, it is characterized by many political, economic, and financial movements such as the worldwide economic NEOM project. The findings provided in the present paper may be applied to predict future GCC markets situation and thus may be a basis for investors’ decisions in such markets.
Design of a Structural Equation Model to Evaluate the Strategic Prospective of SMEs
Authors: Rayas Francisco Sánchez
Published: May 2021

Queretaro is currently one of the states with the highest growth rate in the automotive industry. In the last five years, the number of companies has increased, reaching more than 300 small and medium-sized companies in the sector. However, they show a high degree of ignorance and lack of strategic foresight, which translates into poor planning in the short, medium and long term and low competitiveness, leading many of them to failure. This paper presents the results of a study within a strategic foresight evaluation with the development of a Structural Equation Model that allows the analysis of foresight and strategic planning within the automotive SMEs in the state of Queretaro. The study analyzes the necessary indicators to be evaluated and establishes the relationship of dependence between the variables, which is necessary to create the constructs of the model. It is confirmed that the adjustment of the model used is adequate for the evaluation of SMEs. The contributions of the research were: A theoretical contribution related to strategic foresight within SMEs and the construction of the structural equation model to evaluate strategic foresight in automotive SMEs in the state of Queretaro.
Working Memory Performance under Negative Affect is More Susceptible to Higher Cognitive Workloads with Different Neural Haemodynamic Correlates

Published: May 2021

The effect of stress on task performance is complex, too much or too little negatively affects performance; and there exists an optimal level of stress to drive optimal performance. Task difficulty and external affective factors are distinct stressors that impact cognitive performance. Neuroimaging studies showed that mood affects working memory performance and the correlates are changes in haemodynamic activity in the prefrontal cortex (PFC). We investigate the interactive effects of affective states and working memory load (WML) on working memory task performance and haemodynamic activity using functional near-infrared spectroscopy (fNIRS) neuroimaging on the PFC of healthy participants. We seek to understand if haemodynamic responses could tell apart workload related stress from situational stress arising from external affective distraction. We found that the haemodynamic changes towards affective stressor and workload related stress were more dominant in the medial and lateral PFC respectively. Our study reveals distinct affective state-dependent modulations of haemodynamic activity with increasing WML in n-back tasks, which correlate with decreasing performance. The influence of negative affect on performance is greater at higher WML, and haemodynamic activity showed evident changes in temporal, and both spatial and strength of activation differently with WML.
Creatinine Trends and Patterns in Neonates Undergoing Whole Body Hypothermia: A Systematic Review

Published: May 2021

Many neonates undergoing whole body hypothermia (WBH) following moderate to severe perinatal asphyxia suffer from renal impairment. While recent data suggest a WBH-related reno-protection, the differences in serum creatinine (Scr) patterns to reference patterns were not yet reported. We therefore aimed to document Scr trends and patterns in asphyxiated neonates undergoing WBH, and compared these to centiles reference Scr dataset of non-asphyia neonates. Using a systematic review strategy, reports on Scr trends (mean ± SD, or median and range) were collected (day 1-7) in WBH cohorts, and compared to centiles of an earlier reported reference cohort of non-asphyxia cases. Based on 13 papers on asphyxia+WBH cases, a pattern on postnatal Scr trends in asphyxia+WBH cases was constructed. Compared to the reference cohort, mean or median Scr values at birth (>90th centile) and the first two days of WBH (>75th centile) remained clinical relevantly higher in asphyxia+WBH cases, with a subsequent decline to reach at best high or high normal creatinine values (all >50th centile, but mainly >75th centile) from day 4 onwards. Such patterns are valuable to anticipate average changes in renal clearance capacity relevant for pharmacotherapy, but do not yet cover the relevant inter-patient variability observed in WBH cases.

Published: May 2021

The article is devoted to the methodology for modeling current-carrying plasma in a Z-pinch studied in pulsed-power experiments. We discuss simulation performed via moving Lagrangian-Euler difference grid. The difference scheme approximating the hydrodynamic equations of a high-temperature medium possesses a “complete conservation” property and includes energy balances between the plasma components taking into account electromagnetic field – matter interaction and conductive (electronic, ionic) as well as radiative heat transfer. Numerical experiments provide quantitative estimates of physical effects which lead to essential distortions of a plasma shell during its magnetically-driven implosion. Performed simulations show the effect of instabilities on the final pinch structure, mainly, the hydrodynamic Rayleigh-Taylor instability and instability of a temperature-inhomogeneous plasma
Trans* subjectivities in the higher education curriculum
Authors: Cardoso Helma de Melo , Dias Alfrancio Ferreira
Published: May 2021

This article seeks to problematize the production of trans bodies, abnormal bodies that occur in the production of their genres from the narrative of trans teachers in northeastern universities. Interviews were used in order to locate, describe and problematize the discursive practices of the curriculum in this educational space, focusing on gender norms, heteronorm, and the observation of cracks in hegemonic norms. For that, inspiration was sought in queer analytics, which defends a post-identity and fragmented view in opposition to the hegemonic identity/binary thinking about sexuality and gender studies. Six trans* teachers from northeastern higher education institutions were interviewed. From the analysis, the fixed identities and the hegemonic discourses that imprison them in the binary of the sexes were problematized, taking the body itself as a political power that drives the ruptures operated in the relations of the curriculum.

Pandeyan is a village in Boyolali Regency adjacent bordering directly on Solo Municipal. Such the condition encourages the society to have a variety of school choices. The variety of school choices existing in Solo City encourages the society in Pandeyan Village to enroll their children in Solo City. This research aimed to describe the parents’ decisionconsideration in Determining Basic Education for Children in Pandeyan Village, NgemplakSubdistrict, Boyolali Regency using Weber’s social action theory.

This study was a descriptive qualitative research with descriptive research strategy. The data sources of research were informant, archive, and document. The sampling technique used in this research was purposive sampling, selecting the individuals involved directly in decision making to determine primary education in Pandeyan Village thereby providing the information and data in in-depth manner as well as reliable to be the data source. Techniques of collecting data used in this research were in-depth interview and observation. Source triangulation technique was used to obtain data concerning the parents’ decision in determining basic education for children as well as to validate the data, while the analysis was conducted using a descriptive analysis.

The result of research found three findings: the first was basic education for children, the parent’s perception on education for children become the rationale in acquiring better education. The second was consideration in determining basic education for children encompassing school, social-economic and children considerations. School consideration was based on the school service involving facility and learning services. Social-economic consideration was based on the compatibility of cost to the service for children. Children consideration was based on the children psychology reflected on their interest and willingness. The third was that parents’ decision in determining basic education for the children was the result of parent, social-economic and children considerations in turn becoming the determinant of parent’s action in determining basic (primary) education. The actions emerging in parent’s decision were among other: Instrumental rationality (Zwerkrationalitat) or parent’s decision in choosing school by seeing the quality of school generally, value-oriented rationality (Werkrationalitat) or the parent’s decision in choosing school by seeing religious and academic values as the main foundation, Affective action (Affectival Action) or the parent’s decision in choosing school by seeing children psychology, traditional action or the parent’s submission to receiving strength and weakness as the way they are.

MODERNISASI PENDIDIKAN DI INDONESIA SEBUAH PERSPEKTIF SOSIOLOGIS TERHADAP DUNIA PENDIDIKAN DI INDONESIA
Authors: Primadata Ankarlina Pandu , Kusumawati Dwi Kasi
Published: May 2021

krisis multidimensi yang melanda Indonesia sejak tahun 1997 telah membawa dampak yang luar biasa pada mutu sumber daya manusia (SDM) Indonesia dan juga pada mutu pendidikan di Indonesia. Anthony Giddens menjelaskan konsep modernitas dalam “The Juggernaut Of Modernity”. Giddens menjelaskan bahwa modernitas layaknya sebuah kendaraan besar yang akan terus melaju, menggiring masyarakat untuk terus berlari menuju masa depan. Pendidikan dan kemiskinan adalah dua hal yang saling terkait. Pendidikan seharusnya menjadi hak bagi setiap orang tanpa memandang kaya-miskin seseorang. Namun kenyataannya, pendidikan yang seharusnya menjadi jalur bagi masyarakat miskin untuk dapat memperbaiki kehidupannya, nyatanya tidak dapat berbuat apa-apa ketika orang-orang miskin tersebut justru tersingkirkan darinya dan tidak dapat menggapainya. Ketidakadilan dalam dunia pendidikan semakin terlihat jelas dengan adanya sistematisasi pendidikan, dimana akhirnya terjadi gap antara kelompok orangorang kaya dan kelompok orang-orang miskin dalam dunia pendidikan.

Pilgrimage tour is undertaken as the manifestation of action the visitors or the
tourists do. The objective of research was to find out the tourist type,
knowledge on pilgrimage tour, the factors encouraging and attracting the
tourists to undertake pilgrimage tour, and the tourists’ rationality action in
pilgrimage tour. The theory employed as the instrument of analysis was Max
Weber’s social action theory and Stephen Kalberg’s rationality type.
This study was taken place in pilgrimage tour area in Gunungpring,
Muntilan Subdistrict, Magelang Regency. The type of study was qualitative
with phenomenological strategy. The sampling technique used was accidental
sampling, while the data collection was conducted using direct observation
and in-depth interview methods. The data validation was carried out using data
triangulation technique and data analysis was conducted using data collection,
data reduction, data display and conclusion drawing.
The result of research showed that the pilgrimage tourists were divided
into two types: existential and recreational tourists. The tourists’ knowledge
on pilgrimage tour could be classified into two: modern pilgrimage and search
for pleasure. The factors encouraging and attracting the tourists to undertake
pilgrimage tour were: modern pilgrimage and search for pleasure. The factor
encouraging modern pilgrimage was self-fulfillment, while the attracting one
was culture. The factors encouraging the search for pleasure were social
interaction, educational opportunity, leisure activity, while the attracting one
was location climate. The tourists’ action and rationality in pilgrimage tour
included some action undertaken originating from traditional element, the
present, life ideology values, and psychological conditions affecting an

Evidence-based strategies addressing comorbid hypertension and diabetes are needed among minority communities. We analyzed the outcome of blood pressure (BP) control using pooled data from two community health worker interventions in New York City conducted between 2011 and 2019, focusing on participants with comorbid hypertension and diabetes. The adjusted odds of controlled BP (< 140/90 mmHg) for the treatment group were significant compared with the control group (odds ratio = 1.4; 95% confidence interval = 1.1, 1.8). The interventions demonstrated clinically meaningful reductions in BP among participants with comorbid hypertension and diabetes.

Published: May 2021

The turfgrass lawn is a common feature of urban and suburban communities, often accounting for the largest green spaces by area in these landscapes. Flowering species within turfgrass lawns have the potential to serve as a source of forage for bee pollinators in urban and suburban areas. We intentionally introduced low-growing flowers to turfgrass lawns to promote bee diversity and reduce inputs, while maintaining the traditional aesthetics and recreational uses associated with lawns. We compared bee communities on lawns with naturally-occurring blooms of Trifolium repens to bee communities on florally-enhanced lawns that contained Prunella vulgaris ssp. lanceolata and Thymus serpyllum in addition to T. repens. Trifolium repens provided forage for both wild bee communities and Apis mellifera, with A. mellifera being the most common of the 56 species of bees observed on T. repens. We found that florally-enhanced lawns supported more diverse bee communities than lawns with just T. repens. Furthermore, the bee communities supported by florally-enhanced lawns were significantly different from the bee communities supported by lawns containing just T. repens based on presence-absence (Jaccard’s dissimilarity index). Our research indicates that A. mellifera colonies and wild bee communities can be supported by allowing T. repens to bloom in turfgrass lawns, and that land managers can support more diverse bee communities by intentionally introducing low-growing flowers to lawns.

Published: May 2021

Objectives: In this retrospective study, we investigated whether neutrophil/lymphocyte ratio (NLR) in the last trimester among pregnancies with mild preeclampsia, severe preeclampsia, and healthy status has a role in predicting the severity of pre-eclampsia.Methods: This study involved 933 pregnancies from 1 January 2018 to 30 September 2020, comprising 396 healthy pregnancies, 222 pregnancies with mild preeclampsia, and 315 pregnancies with severe preeclampsia. The relationship between preeclampsia and NLR was analyzed by multiple logistic regression. In addition, maternal placental tissues of three groups were immunohistochemically stained for myeloperoxidase (MPO).Result: NLR was significantly higher in pregnancies with preeclampsia (including pregnancies with mild and severe preeclampsia.) than that in healthy pregnancies. The NLR level was prominently higher in patients with severe preeclampsia compared with those with mild preeclampsia (p<0.001). The NLR level was significantly positively associated with preeclampsia after adjusting for gestational week at time of blood sampling, BMI, and age (β:1.44; 95%CI:0.01-2.93; p=0.0014 < 0.05). In addition, MPO expressions of placental tissues in preeclamptic groups were significantly increased than these in healthy pregnant controls(P＜0.05). Conclusion: Increased NLR in the last trimester was significantly positively associated with preeclampsia. Hence, NLR plays a role in predicting the severity of preeclampsia. However, further studies are needed on a more extensive population to confirm the relationship between NLR and preeclampsia severity.
On Intlet Pressure Boundary Conditions for CT-Based Computation of FFRSS: Clinical Measurement of Aortic Pressure
Authors: Liu Jincheng , Wang Xue , Ma Junling , Liu Jian , Liu Youjun
Published: May 2021

Background and Objectives: With the development of medical imaging and computational fluid dynamics (CFD), a fast calculation method of steady-state fractional flow reserve (FFRss) based on CTA images has been applied to predict myocardial ischemia. Whilst this is a reliable non-invasive method of calculating FFR, assumptions involved in the analysis still need to be investigated for further improvement in predictive accuracy. In this study, we analyzed the influence of inlet and outlet boundary conditions on FFRSS.Methods: A clinical trial was carried out in Peking University People's Hospital. We enrolled 15 patients with coronary heart disease. All patients underwent coronary CTA examination, aortic pressure measurement and FFR catheter surgery. In order to better reflect the relationship between different entrance boundary conditions and FFRss, we used the invasive measurement of FFR as the standard, and calculated FFRss for 15 patients with coronary heart disease with different degrees of stenosis. The boundary conditions are divided into two groups: (1) pressure calculated based on physiological formula; (2) clinically measured aortic pressure. Based on the boundary conditions calculated by the physiological formula, we further studied the changes of FFRss under different coronary vasodilation responses (12%-48% baseline).Results: The research results show that although the pressure difference between the two pressure boundary conditions is 15mmHg, the FFRss calculation result does not change significantly. With the change of the vasodilation state, the microcirculation resistance of the exit boundary condition gradually increased, and the calculated FFR value increased.Conclusions: We found that changes in the microcirculation resistance of coronary stenoses have a huge impact on FFRss. The changes in FFRss values caused by boundary conditions are due to the overestimation of the vasodilation response. Therefore, individualizing the hyperemia state of the stenotic vessel microcirculation resistance value is an effective method to improve the calculation of FFR.

Published: May 2021

Background: Acute necrotizing encephalopathy (ANE) is a rare acute encephalopathy secondary to infection, which is characterized by convulsion and disturbance of consciousness. Besides, recurrent cases with family history are rarer. To the best of our knowledge, only 12 cases reported were recurrent with family history of encephalopathy in the world. The aim of this study is to report a rare case of recurrent ANE with family history of encephalopathy to provide clinical data for future research of ANE.Case report: A boy had a history of febrile convulsions when he was 1 year old. A few years later, he was hospitalized twice because of convulsions when he was 4 years old and 7 years old. Computed tomography (CT) and magnetic resonance imaging (MRI) were performed on two hospitalizations. Brain CT in the first admission showed low density lesions in bilateral temporal lobes hippocampus and further MRI after 3 days found lesions in bilateral temporal lobe hippocampus, insular lobes, ventrolateral thalamus and pons. Due to the bilateral and symmetrical lesions, metabolic diseases were suspected. When the boy was 7 years old, brain CT was normal while MRI showed multiple lesions in bilateral thalamus, left hippocampus and brainstem. According to the boy's clinical data and MRI findings, pediatrician diagnosed the child as ANE.

Anaerobic Treatment of Oily Wastewater Using A Biofilm-Electrode Reactor: A Kinetic Study And Energy Consumption
Authors: Mirshafiee Amir , Rezaee Abbas
Published: May 2021

The present study introduced a laboratory-scale, anaerobic treatment system for the removal of oil from synthetic wastewr using a biofilm-electrode reactor (BER). The operating parameters of current intensity, initial concentration, reaction time, and supporting electrolyte were investigated. The results of the present study showed that the optimal conditions were: a current intensity of 15 mA, COD concentration of 1500 mg/L, a reaction time of three days, and a supporting electrolyte (NaCl) of 150 mg/L. The highest efficiency for the removal of COD was 86.7% using the introduced method, while it was 65.9% using biological processes. Increased efficiency was attributed to the employment of the proposed bioelectrochemical system that stimulated bacterial growth. In the present study, the energy consumed by the bioelectrochemical system was 1.914 kWh/m3. The kinetic study indicated that the removal reaction was more consistent with the modified Stover-Kincannon model. The present study findings indicated that BER is a promising method for the treatment of oil-contaminated wastewaters.

BackgroundIn microbial ecology, the processes underlying functional community assembly and spatiotemporal effect are often ignored. The effects of land management and reclamation of coastal marshes on microbial communities have been studied with great interest; however, most of these studies have described short-term changes in soil microbial community dynamics. Therefore, ammonia-oxidising prokaryotic communities that play an essential role in nitrogen cycling have not been studied in long-term reclamations of coastal marshes. Here, we investigated archaeal and bacterial ammonia-oxidising prokaryotic communities in coastal salt marsh soils that were reclaimed over 1000 years, evaluating the abundance, composition, taxonomic and phylogenetic diversity by using qPCR and IonS5TMXL sequencing platforms. We analysed phylogenetic diversity and assemblages of ammonia oxidisers using the Nearest Related Index , Nearest Taxon Index , beta Mean Nearest Taxon Distance and beta Nearest Taxon Index . ResultsThe taxonomic & phylogenetic alpha diversity and composition of the ammonia-oxidizers showed apparent spatiotemporal variations along reclamation of soil. Phylogenetic beta diversity indices, Weighted UniFrac dissimilarity and beta Mean Nearest Taxon Distance of both communities were positively correlated with geographical distance and environmental variables. Across all sites, the archaeal ammonia-oxidising community assembled by a deterministic process (84.71%). The bacterial ammonia-oxidising community was formed more by a stochastic process in coastal marshes and at reclamation stage 60 years (|βNTI|<2), despite its relatively dominant deterministic process (55.2%). Archaeal amoA gene abundance increased significantly among reclamation stages and was positively correlated with the nitrification rate. ConclusionOur study revealed that during the 1000 years of reclamation coastal wetlands (1) a clear spatiotemporal evolution of the amoA gene harboured prokaryotic communities; (2) the soil properties and N cycling were significantly affected; and (3) the significant impact on ammonia oxidisers assemblages’ dynamics. These findings provide a better understanding of how long-term land management affect soil N cycling and ammonia-oxidising communities including assembly dynamics, abundance and community distribution. Further researches are needed to study the effect of soil disruption and community assembly processes on soil nitrogen cycling, such as nitrogen fixation and denitrification, in order to exploit the functional microbial population in predictable ways, improve crop yields and soil sustainability.
A rare and interesting case of desmoid-type fibromatosis arising from the fat layer of the abdominal wall: A case report

Background

Desmoid-type fibromatosis (DTF) is a rare kind of soft-tissue tumors of unknown origin, which is a benign mesenchymal neoplasm with monoclonal proliferation with local invasion, easy recurrence and non-distant metastasis. It is usually arising from the aponeurosis, muscle, and deep fascia, but DTF arsing from the fat layer have not been previously reported.
Case presentation:

A 22-year-old male was presented with a recurrence of lower abdominal wall mass(LAWM) after multiple operations and a new mass in the skin flap donor area of the right abdominal wall. Magnetic resonance imaging (MRI) revealed multiple soft tissue masses and nodules in the subcutaneous fat layer of the lower abdomen and right abdomen wall, which was considered a diagnosis of fibrosarcoma, then pathological consultation was performed on the paraffin specimens from previous operations, and finally confirmed the diagnosis of desmoid-type fibromatosis in combination with pathological characteristics of the resected specimens in this visit. In general, DTF did not have the ability to metastasize, but we extracted paraffin sections and performed full exon sequencing. After personalized analysis, the results showed that there was a possibility of implantative metastasis. Due to the aggressive growth and recurrence of the tumor, the patient was subsequently treated with radiotherapy and no recurrence was observed 6 months later. Continued follow-up is ongoing.
Conclusions

We report the first case of DTF that occurs in the superficial layer of fat with the possibility of surgically induced implantative metastasis, for such patients, diagnosis of DTF is more difficult and surgical treatment should be treated with greater caution.
Modeling the impact of culture facilities on hydrodynamic and solute transport in marine aquaculture waters of the North Yellow Sea
Authors: Jiang Hengzhi , Ji Yongpeng , Zhang Mingliang
Published: May 2021

An increasing number of marine aquaculture facilities are being placed in shallow bays and open sea. In this study, we present a coupled hydrodynamic and solute transport model with high-resolution schemes in marine aquaculture waters based on depth-averaged shallow water equations. A new expression of drag force is incorporated into momentum equations to express the resistance of suspended culture cages. The coupled model is used to simulate the effect of suspended structures on the tidal current and the motion of a contaminant cloud in the marine aquaculture of the North Yellow Sea, China. Simulation results show a low-velocity area inside the aquaculture cage area, with a maximum reduction rate of velocity close to 45% under high-density culture. The results also show that the tidal currents are sensitive to the suspended cage densities, cage length and drag coefficients of cages. The transport processes of pollutants inside aquaculture facilities are inhibited away from the vicinity of the culture cage area because of the reduction in tidal currents; therefore, the suspended cages significantly affect the transport processes of pollutants in coastal aquaculture waters. Furthermore, the reduction in the horizontal velocity can significantly decrease the food supply for aquaculture areas from the outside sea. The results of this study provide new insight into the planning of high-density suspended facilities for coastal aquaculture activities.

The aim of this study was to evaluate the antibacterial efficacy of copper added chitosan nanoparticles (CU-CNPs) as an irrigation solution with different irrigants in terms of eliminating Enterococcus Faecalis (E. faecalis) from the root canals. Fifty mandibular premolar teeth were prepared and infected with E. faecalis for 21 days. After the incubation period, samples were randomly divided into a control group irrigated with distilled water and 4 experimental groups (n = 10) irrigated with as follows, %6 NaOCl, %6 NaOCl + %9 editronate (HEBP), Chitosan nanoparticles (CNPs), and CU-CNPs. To calculate the proportion of dead E. faecalis cell volume, stained using LIVE/DEAD BacLight Bacterial Viability Kit and were scanned using confocal laser scanning microscope (CLSM). All the irrigation solutions significantly (P < .05) killed the bacteria in the canal, except for the control group. CU-CNPs solution killed the highest (P < .05) number of bacteria compared with the other experimental groups. No significant difference was found between CNPs, NaOCl + HEBP and NaOCl in terms of antibacterial activity. CU-CNPs solution was exhibited higher antibacterial efficacy against E. faecalis.
Backstepping sliding mode control for coupled delayed time fractional reaction diffusion systems subject to boundary input disturbances
Authors: Chen Juan , Zhuang Bo , Chen YangQuan , Yu Yajuan
Published: May 2021

In this paper we develop backstepping-based boundary sliding mode controllers for coupled time fractional reaction diffusion (FRD) systems governed by time fractional partial differential equations (PDEs) with time varying delay and input disturbances. Here, the diffusion coefficients are spatially varying (nonconstant) and can be same or different. To asymptotically stabilize the system, we first use a backstepping transformation to convert the original dynamics into a target dynamics with a new manipulable input and the perturbation. Then, the sliding mode algorithm is employed to design this discontinuous controller to suppress disturbances. In this case, we obtain the combined backstepping/sliding mode controller of the original dynamics, with which the closed-loop asymptotic stability is proved by the fractional Halanay's inequality. Fractional numerical examples are given to demonstrate the efficiency of the proposed synthesis.
