Authors: Upadhyay Nikee , Shah Monali , Raval Yesha 
Published: September 2021

Introduction:
A newly identified viral infection, a global pandemic of coronavirus disease 2019, that began in Wuhan, China, and spread around the world, causing an epidemic of pneumonia (COVlD-19), has infected millions of population, causing social anxiety and panic amongst healthcare professionals and the general public. This study aimed to measure the dentists' anxiety and apprehension of being infected while operating during the latest coronavirus disease (COVlD-19) epidemic through a web-based questionnaire.

Materials and Methods:
An online survey was used to perform a cross-sectional analysis. The well-constructed questionnaire, which consisted of closed-ended questions, was prepared and submitted to dentists of India. A total of 396 people from all over India took part in the survey.

Results:
The debilitating consequences of COVlD-19 caused anxiety and fear in a total of 55.8% of general dental practitioners in India. There were 373 dentists (94.2%) who were mindful of recent developments in care procedures. The majority of dentists, 316 (79.8%), are fearful of contracting COVID-19 from a patient or co-worker, and 309 (78%) dentists are nervous when treating a patient with COVID-19.

Conclusion:
Indian dentists revealed good information regarding COVID-19. However, dentists were comprehensive about the extra precautionary measures that protect them about the virus. A considerable percentage of dentists reflected their anxiety and worries about dental profession due to which they have either changed their services to comply with the rules or shut down their practices for an indefinite time.

Published: September 2021

Introduction:
Cervical spine injuries were the most common problem nowadays that many people experiencing due to high-intensity trauma. In contrast, substantial heterogeneity and lack of data exist among clinical spine trauma epidemiological studies limiting the ability to compare and pool data. The most common mechanism of injury is usually motor vehicle accidents. However, its patient-centered characterisation and quantification are lacking.

Materials and Methods:
Incidence and characteristics of cervical spine injury were identified in the tertiary care hospital of Delhi. Fifty-six cervical spine injuries admitted patients among all 228 spinal trauma patients who presented in the orthopaedic trauma emergency registry were recruited in this study.

Results:
There were 56 subjects identified (8.53%) with cervical spine injury admitted per further evaluation. Among these, 85.7% were male. Mainly age group involve is 20–40 year (median age – 24 year), mostly injured by road traffic accident (RTA) (35.7%). The cervical injury commonly has upper, and subaxial vertebrae fractures and anterolisthesis are much common than retrolisthesis. The hospital stay of listhesis patient is usually more than disc bulge patients. Halovent application is more common in the upper cervical (c1–c2), like anterior cervical plating with dissectomy is common in disc bulge cervical patients.

Conclusion:
Cervical spinal injury is associated with RTA in the young age group. A head injury like trauma should take into consideration in every cervical patient. Early management with better operative techniques can decrease hospital stay and increase the recovery rate of patients.
Predicting the 7th Day Efficacy of Acupoint Application of Chinese Herbs (Xiao Zhong Zhi Tong Tie) in Patients with Diarrhea – A Machine-Learning Model Based on XGBoost Algorithm
Authors: Sheng Song , Li Rui , Wang Xing , Gao Hong-Yang , Zhang Yan-Hong , Xu Feng-Qin 
Published: September 2021

Objective:
Extreme gradient boosting (XGBoost) was used to predict the 7th day efficacy of the acupoint application (AP) of Chinese herbs (Xiao Zhong Zhi Tong Tie) in patients with diarrhea.

Materials and Methods:
We consecutively collected medical records of patients with diarrhea nationwide on the Chun Bo Wan Xiang cloud platform from August 22 to November 5, 2020. Demographic and clinical data and the fecal properties were included in this study. We established the XGBoost model to predict the 7th day efficacy of AP in patients with diarrhea. The XGBoost model was evaluated using the area under the receiver operating characteristic (ROC) curve (AUC). We next compared the performance of XGBoost with that of artificial neural network (ANN), ANN + boosting, ANN + bagging, and support vector machine (SVM).

Results:
The XGBoost model provided a prediction accuracy of 84.86% (95% confidence interval = 82.74% to 86.81%) and the ROC curve analysis showed an AUC of 0.81. The top-three variables with the highest importance are age, duration of diarrhea, and region (North). Our study revealed that XGBoost was not superior to ANN, ANN + boosting, ANN + bagging, and SVM.

Conclusions:
The established XGBoost model for predicting the 7th day efficacy of AP in patients with diarrhea exhibited good accuracy and precision, which can be used for efficacy prediction.
A Susceptible Exposed Infected Recovered Susceptible (SEIRS) Model for the Transmission of Tuberculosis
Authors: Erinle-Ibrahim Latifat M. , Lawal Waheed O , Adebimpe Olukayode , Sontan Gbemisola R 
Published: September 2021

In this paper, a deterministic mathematical model was proposed and analyzed to understand the dynamics of tuberculosis based on the SEIRS model. The disease-free equilibrium, the endemic equilibrium, and their stabilities were examined. The R0 (basic reproduction number) was derived using the Next Generation Matrix method and its sensitivity analysis showed that the birth rate and infectious rate were the most sensitive parameters of R0. The behaviour of exposed individuals at the latent period with varied treatment rates were examined through numerical simulation. From the analysis carried out, the effect of variations of the treatments of latent TB shows that it affects the disease burden. This implies that testing and treatment of latent TB are important in preventing it from becoming infectious. The re-infection rate was examined to see the effect it had both on the recovered and susceptible populations. The study concludes by recommending the extension of the model to an age structured model with co-infection with another respiratory infectious disease like COVID-19.

Published: September 2021

Railways, being the basis of the country's transport system, provide timely and high-quality satisfaction of the needs of shippers and consignees in transportation. One of the most effective ways of cargo delivery is container transportation.For the transportation of containers, specialized rolling stock is used — platform cars equipped with special container attachment points — fitting stops. The design of stops for container fittings limits the spontaneous displacement of containers, prevents them from tipping over. Various designs of fitting stops are used in practice and exist only in the information representation in the form of patents and technical documentation. As a result of the comparative and statistical analysis, similarities and differences in the design were established, and common features were determined. The designs of stops and devices for fixing containers on platforms used in Kazakhstan and the United States are considered. The presented classification of fitting stops is based on the results of the analysis of the structures of fitting stops installed on specialized platform cars operated in the Russian Federation. Fitting stops of specialized platform cars for container transportation are classified in three directions.The classification obtained as a result of the study allows us to establish the uniformity of the structures used for fitting stops of platform cars for the transport of containers and opens up the possibility of finding a way to improve certain structures united by common features.

Aim. To determine the frequency of local recurrence of breast cancer (BC) after performing breast-conserving surgery (BCS) during and after complex treatment, to study the risk factors for local recurrence and survival.Materials and methods. A retrospective cohort study of 675 patients with breast cancer who underwent BCS followed by remote radiotherapy was conducted. The frequency of local relapse and risk factors were studied, 3- and 5-year local-free survival. The odds ratios (OR) and 95% confidence intervals (CI) were calculated, and the Kaplan–Meyer curves were constructed.Results. Radical breast resections (RBR) were performed in 46.7% of patients, and oncoplastic breast resections (OBS) in 53.3% of patients. The most common histological type in both groups was invasive cancer with no signs of specificity: 76.9% and 84.1% – in the OBS and RBR groups, respectively. The incidence of cancer in situ was higher in the OBS group: 14.7% vs. 3.3% in the RBR group (p < 0.001), metastases in regional lymph nodes were more frequent in the RBR group: 34.3% against 20.3% in OBS (p < 0.001). According to the immunohistochemical type and degree of differentiation, the groups did not differ. For 3 years, the relapse-free survival rate was 99.7% in both groups, and for 5 years – 99.2% in the OBS group. and 99.7% in the RBR group, 6 years – 98.3% and 98.7%, respectively; no significant differences were found between the groups. There were no statistically significant differences in the frequency of relapses depending on the width of the resection edges from <1 to ≥10 mm. The risk of relapse was increased with a preserved menstrual status (OR 20.05; 95% CI 2.52–159.33), Her2/neu–positive (OR 5.11; 95% CI 1.04–25.09) and triple-negative types (OR 4.02; 95% CI 1.02–15.95), the degree of differentiation of G3 (OR 5.58; 95% CI 1.59–19.64).Conclusion. BCS is characterized by oncological safety; the rate of local relapse within 6 years is 1.5%. Risk factors for relapse include active menstrual status, highly aggressive immunohistochemical types of breast cancer, and low degree of differentiation.

La producción local de un sector debe llegar al consumidor final a través de diferentes medios de comercialización con acciones planeadas de los agricultores que le permitan posicionar mejor sus productos en el mercado. El recinto San Vicente, sector del cantón Jipijapa y sus 45 familias, viven del sembrío de varios productos, entre los que se destaca el maíz, sin embargo, no cuentan con mercados específicos donde venderlos a precios rentables. Los productores carecen de estrategias para comercializarlos, lo que afecta su bienestar y calidad de vida. Por ello, determinar las formas de comercialización de maíz y el desarrollo socioeconómico de sus productores a través de una metodología de tipo descriptiva apoyada en los métodos inductivo y deductivo, permitió identificar que la forma cómo se comercializa el producto no es la más beneficiosa y el precio que pagan los intermediarios no siempre es el más justo lo que afecta recuperar la inversión y obtener ganancias para sustentar sus necesidades básicas y mejorar sus estatus socioeconómico.
Lagrangian eddy tracking reveals the Eratosthenes anticyclonic attractor in the eastern Levantine Basin
Authors: Barboni Alexandre , Lazar Ayah , Stegner Alexandre , Moschos Evangelos 
Published: September 2021

Abstract. Statistics of anticyclonic eddy activity and eddy trajectories in the Levantine Basin over the 2000–2018 period are analyzed using the DYNED-Atlas database, which links automated mesoscale eddy detection by the Angular Momentum Eddy Detection and Tracking Algorithm (AMEDA) algorithm to in situ oceanographic observations. This easternmost region of the Mediterranean Sea, delimited by the Levantine coast and Cyprus, has a complex eddying activity, which has not yet been fully characterized. In this paper, we use Lagrangian tracking to investigate the eddy fluxes and interactions between different subregions in this area. The anticyclonic structure above the Eratosthenes Seamount is identified as hosting an anticyclone attractor, constituted by a succession of long-lived anticyclones. It has a larger radius and is more persistent (staying in the same position for up to 4 years with successive merging events) than other eddies in this region. Quantification of anticyclone flux shows that anticyclones that drift towards the Eratosthenes Seamount are mainly formed along the Israeli coast or in a neighboring area west of the seamount. The southeastern Levantine area is isolated, with no anticyclone transfers to or from the western part of the basin, defining the effective attraction basin for the Eratosthenes anticyclone attractor. Co-localized in situ profiles inside eddies provide quantitative information on their subsurface physical anomaly signature, whose intensity can vary greatly with respect to the dynamical surface signature intensity. Despite interannual variability, the so-called Eratosthenes anticyclone attractor stores a larger amount of heat and salt than neighboring anticyclones, in a deeper subsurface anomaly that usually extends down to 500 m. This suggests that this attractor could concentrate heat and salt from this subbasin, which will impact the properties of intermediate water masses created there.
Exploitation of the far-offshore wind energy resource by fleets of energy ships – Part 2: Updated ship design and cost of energy estimate

Published: September 2021

Abstract. This paper deals with a new concept for the conversion of
far-offshore wind energy into sustainable fuel. It relies on autonomous
sailing energy ships and manned support tankers. Energy ships are
wind-propelled ships that generate electricity using water turbines attached
underneath their hull. Since energy ships are not grid-connected, they
include onboard power-to-X plants for storage of the produced energy. In the
present work, the energy vector X is methanol. In the first part of this study, an energy ship design was proposed, and
its energy performance was assessed. In this second part, the aim is to
update the energy and economic performance of
such a system based on design progression. In collaboration with ocean engineering, marine renewable energy and
wind-assisted propulsion experts, the energy ship design of the first part
has been revised. Based on this new design, a complete FARWIND energy system
is proposed, and its costs (CAPEX and OPEX) are estimated. Results of the
models show (i) that this FARWIND system could produce approximately 70 000 t of methanol per annum (approximately 400 GWh per annum of chemical
energy) at a cost in the range EUR 1.2 to 3.6/kg, (ii) that this cost
may be comparable to that of methanol produced by offshore wind farms in the
long term and (iii) that FARWIND-produced methanol (and methanol produced by offshore wind
farms) could compete with gasoline on the EU
transportation fuel market in the long term.
