Advances in Carbidic Austempered Ductile Iron (CADI) - A Wearresistant Material
Authors: Maddi Lakshmiprasad , Likhite Ajay
Published: April 2021

Background:

Ductile irons provide a more viable alternative for malleable cast iron in
areas that do not demand extreme wear resistance. Austempering of ductile irons was a well researched
area in the last two decades. Attempts to further improve the wear resistance led to the
development of Carbidic austempered ductile iron (CADI), wherein the carbides contribute to wear
resistance. Combination of ausferritic matrix, graphite nodules, and carbides (eutectic and alloy)
symbolizes the microstructure of CADI.

Methods:

Two principal approaches adopted by the researchers to change the microstructure are (i)
addition of carbide forming elements (ii) heat treatment (s).

Results:

Both the above methods result in the refinement of graphite nodules, carbide precipitations,
along fine ausferrite.

Conclusion:

Improvement in hardness, toughness and wear resistance was observed largely as a
consequence of fine carbide precipitations and formation of martensite.

The paper presents the AISI 316L stainless steel surface modification by plasma-assisted chemical vapor deposition of a-C:H:SiOx film using the pulsed bipolar substrate bias voltage. The mechanical and tribological properties of the a-C:H:SiOx film and the steel surface are examined using the nanoindentation method and the pin-on-disk tribometer, respectively. The optimum value is obtained for the amplitude of the negative pulse of the bipolar bias voltage, when the hardness of the a-C:H:SiOx film is high (19±2 GPa). This hardness value is 3.5 times greater, than the hardness of the AISI 316L steel surface (5.5±0.1 GPa). At the same time, the coefficient of friction of the film is low (0.08), which is 9 times lower than that of the steel (0.72). The wear rate values are found to be 8.5×10-7 and 3.7×10-5 mm3N-1m-1 for the coated and uncoated steel, respectively. The structure and composition of the obtained films are studied by Raman spectroscopy and scanning electron microscopy.

Published: April 2021

BACKGROUND

Remote consultations help reduce the level of contact between people and prevent cross-contamination. Little is known about the changes in consultation in European rural primary care during the Covid-19 pandemic.

OBJECTIVE

The purpose of our mixed method cross sectional study was to find out more about the effects of Covid-19 pandemic on patient consultation in European primary care.

METHODS

Key informant survey from sixteen member countries of the European Rural and Isolated Practitioners Association using a 48-item questionnaire. Proportions were calculated for dichotomized or categorized data, and means were calculated for continuous data. Multivariate analysis by logistic regression model was used to assess the association of multiple variables.

RESULTS

We collected questionnaires from 406 primary care informants in 16 European countries; 245 respondents (60.5%) were females. 152 PC informants were rural (37.5%), 124 semi-rural (30.5%). Mean age of the respondents was 45.9 years (SD 11.30) while seniority (mean) was 18.2 years (SD 11.6). 381 (93.8 %) of the respondents were medical doctors. Significant differences were found between countries in adopting alternative arrangements for face-to-face consultation: remote teleconsultation is well appreciated by both healthcare professionals and patients, but the most common way of remote consultation remains telephone consultation. A factor significantly inversely associated with the adoption of video consultation was the seniority of the primary care health care personnel OR: 1.19, 95% CI (1.02-1.40) P=0.03.

CONCLUSIONS

Telephone consultation is the most common form of remote consultation. The adoption of video-consultation is inversely related to the seniority of the informants.

Published: April 2021

BACKGROUND

Research in mental health has found associations between depression and individuals’ behaviors and statuses, such as social connections and interactions, working status, mobility, and social isolation and loneliness. These behaviors and statuses can be approximated by the nearby Bluetooth device count (NBDC) detected by Bluetooth sensors in mobile phones.

OBJECTIVE

This study aimed to explore the value of the NBDC data in predicting depressive symptom severity as measured via the 8-item Patient Health Questionnaire (PHQ-8).

METHODS

The data used in this paper included 2886 biweekly PHQ-8 records collected from 316 participants recruited from three study sites in the Netherlands, Spain, and the United Kingdom as part of the EU Remote Assessment of Disease and Relapse-Central Nervous System (RADAR-CNS) study. From the NBDC data 2 weeks prior to each PHQ-8 score, we extracted 49 Bluetooth features, including statistical features and nonlinear features for measuring the periodicity and regularity of individuals’ life rhythms. Linear mixed-effect models were used to explore associations between Bluetooth features and the PHQ-8 score. We then applied hierarchical Bayesian linear regression models to predict the PHQ-8 score from the extracted Bluetooth features.

RESULTS

A number of significant associations were found between Bluetooth features and depressive symptom severity. Generally speaking, along with depressive symptom worsening, one or more of the following changes were found in the preceding 2 weeks of the NBDC data: (1) the amount decreased, (2) the variance decreased, (3) the periodicity (especially the circadian rhythm) decreased, and (4) the NBDC sequence became more irregular. Compared with commonly used machine learning models, the proposed hierarchical Bayesian linear regression model achieved the best prediction metrics (R2=0.526) and a root mean squared error (RMSE) of 3.891. Bluetooth features can explain an extra 18.8% of the variance in the PHQ-8 score relative to the baseline model without Bluetooth features (R2=0.338, RMSE=4.547).

CONCLUSIONS

Our statistical results indicate that the NBDC data have the potential to reflect changes in individuals’ behaviors and statuses concurrent with the changes in the depressive state. The prediction results demonstrate that the NBDC data have a significant value in predicting depressive symptom severity. These findings may have utility for the mental health monitoring practice in real-world settings.

Published: April 2021

BACKGROUND

A growing number of studies have reported artificial intelligence (AI) has been developed for diagnosis and outcome prediction in clinical practice. Furthermore, AI in digestive endoscopy has attracted much attention, which has shown promising and stimulating results.

OBJECTIVE

Our study aimed to visualize the articles to determine the trends and hotspots of AI in digestive endoscopy.

METHODS

Publications on AI in digestive endoscopy research were retrieved from the Web of Science Core Collection (WoSCC) on March 14, 2021. Microsoft Excel 2016, VOSviewer 1.6.11.0, and CiteSpace V were used to assess and plot the research output.

RESULTS

The analytic research was based on original articles and reviews. A total of 121 records of AI research in digestive endoscopy published from 2017 to 2021 were retrieved. The citation number for these articles ranged from 0 to 142. The number of published articles increased 68-fold just from 2017 to 2020. All publications were distributed among 31 countries and 296 institutions. Asian countries had the most publications in this field (80.17%). Among the 31 countries, China and Japan were consistently the leading driving force and contributed mostly (31.40% and 28.93%, respectively), with a strong academic reputation in this area. Tada Tomohiro distributed the most related articles (13.22%) and was cited the most frequently. Gastrointestinal endoscopy published the largest number of publications (14.88%), and 4 of the top 10 cited references were in this leading journal. “Barrett’s esophagus” was the leading research hotspot. The keywords “classification,” “polyps,” “risk,” “histology,” and “resection” appeared most recently as research frontiers.

CONCLUSIONS

Our study provides a systematic elaboration for researchers to obtain a good comprehension of AI development in digestive endoscopy.
Factors Influencing the Popularity of a Health-Related Answer on a Chinese Question-and-Answer Website: Case Study (Preprint)
Authors: Li Jinhui , Zheng Han , Duan Xu
Published: April 2021

BACKGROUND

Social question-and-answer (Q&A) sites have become an important venue for individuals to obtain and share human papillomavirus (HPV) vaccine knowledge.

OBJECTIVE

This study aims to examine how different features of an HPV vaccine–related answer are associated with users’ response behaviors on social Q&A websites.

METHODS

A total of 2953 answers and 270 corresponding questions regarding the HPV vaccine were collected from a leading Chinese social Q&A platform, Zhihu. Three types of key features, including content, context, and contributor, were extracted and coded. Negative binomial regression models were used to examine their impact on the vote and comment count of an HPV vaccine–related answer.

RESULTS

The findings showed that both content length and vividness were positively related to the response behaviors of HPV vaccine–related answers. In addition, compared with answers under the question theme benefits and risks, answers under the question theme vaccination experience received fewer votes and answers under the theme news opinions received more votes but fewer comments. The effects of characteristics of contributors were also supported, suggesting that answers from a male contributor with more followers and no professional identity would attract more votes and comments from community members. The significant interaction effect between content and context features further showed that long and vivid answers about HPV vaccination experience were more likely to receive votes and comments of users than those about benefits and risks.

CONCLUSIONS

The study provides a complete picture of the underlying mechanism behind response behaviors of users toward HPV vaccine–related answers on social Q&A websites. The results help health community organizers develop better strategies for building and maintaining a vibrant web-based community for communicating HPV vaccine knowledge.

Published: April 2021

BACKGROUND

The COVID-19 pandemic has prompted the increasing popularity of several emerging therapies or preventives that lack scientific evidence or go against medical directives. One such therapy involves the consumption of chlorine dioxide, which is commonly used in the cleaning industry and is available commercially as a mineral solution. This substance has been promoted as a preventive or treatment agent for several diseases, including SARS-CoV-2 infection. As interest in chlorine dioxide has grown since the start of the pandemic, health agencies, institutions, and organizations worldwide have tried to discourage and restrict the consumption of this substance.

OBJECTIVE

The aim of this study is to analyze search engine trends in Mexico to evaluate changes in public interest in chlorine dioxide since the beginning of the COVID-19 pandemic.

METHODS

We retrieved public query data for the Spanish equivalent of the term “chlorine dioxide” from the Google Trends platform. The location was set to Mexico, and the time frame was from March 3, 2019, to February 21, 2021. A descriptive analysis was performed. The Kruskal-Wallis and Dunn tests were used to identify significant changes in search volumes for this term between four consecutive time periods, each of 13 weeks, from March 1, 2020, to February 27, 2021.

RESULTS

From the start of the pandemic in Mexico (February 2020), an upward trend was observed in the number of searches compared with that in 2019. Maximum volume trends were recorded during the week of July 19-25, 2020. The search volumes declined between September and November 2020, but another peak was registered in December 2020 through February 2021, which reached a maximum value on January 10. Percentage change from the first to the fourth time periods was +312.85, –71.35, and +228.18, respectively. Pairwise comparisons using the Kruskal-Wallis and Dunn tests showed significant differences between the four periods (P<.001).

CONCLUSIONS

Misinformation is a public health risk because it can lower compliance with the recommended measures and encourage the use of therapies that have not been proven safe. The ingestion of chlorine dioxide presents a danger to the population, and several adverse reactions have been reported. Programs should be implemented to direct those interested in this substance to accurate medical information.
Exploring the Utility of Google Mobility Data During the COVID-19 Pandemic in India: Digital Epidemiological Analysis (Preprint)
Authors: Kishore Kamal , Jaswal Vidushi , Verma Madhur , Koushal Vipin
Published: April 2021

BACKGROUND

Association between human mobility and disease transmission has been established for COVID-19, but quantifying the levels of mobility over large geographical areas is difficult. Google has released Community Mobility Reports (CMRs) containing data about the movement of people, collated from mobile devices.

OBJECTIVE

The aim of this study is to explore the use of CMRs to assess the role of mobility in spreading COVID-19 infection in India.

METHODS

In this ecological study, we analyzed CMRs to determine human mobility between March and October 2020. The data were compared for the phases before the lockdown (between March 14 and 25, 2020), during lockdown (March 25-June 7, 2020), and after the lockdown (June 8-October 15, 2020) with the reference periods (ie, January 3-February 6, 2020). Another data set depicting the burden of COVID-19 as per various disease severity indicators was derived from a crowdsourced API. The relationship between the two data sets was investigated using the Kendall tau correlation to depict the correlation between mobility and disease severity.

RESULTS

At the national level, mobility decreased from –38% to –77% for all areas but residential (which showed an increase of 24.6%) during the lockdown compared to the reference period. At the beginning of the unlock phase, the state of Sikkim (minimum cases: 7) with a –60% reduction in mobility depicted more mobility compared to –82% in Maharashtra (maximum cases: 1.59 million). Residential mobility was negatively correlated (–0.05 to –0.91) with all other measures of mobility. The magnitude of the correlations for intramobility indicators was comparatively low for the lockdown phase (correlation ≥0.5 for 12 indicators) compared to the other phases (correlation ≥0.5 for 45 and 18 indicators in the prelockdown and unlock phases, respectively). A high correlation coefficient between epidemiological and mobility indicators was observed for the lockdown and unlock phases compared to the prelockdown phase.

CONCLUSIONS

Mobile-based open-source mobility data can be used to assess the effectiveness of social distancing in mitigating disease spread. CMR data depicted an association between mobility and disease severity, and we suggest using this technique to supplement future COVID-19 surveillance.

The goals of the Mongol invaders according to European sources of the middle of the XIII century. Part 1
Authors: Drobyshev Yuliy I.
Published: April 2021

The middle of the XIII century - the apogee of power of the unified Mongol Empire. In 1241-1242, the first, bloodiest and most destructive Mongol invasion into Europe took place. Certainly, it was vital for the Europeans to find an answer to the question: what did the invaders want, what goals did they pursue? In this article, the author shows that, due to the abundance of contradictory information and the acute lack of an objective understanding of the new enemy at first, European political and ecclesiastical figures attributed many goals to the Mongols (at least eighteen!), of which only three were fully confirmed - an attack on Russia, Poland, and Hungary, and the rest were either not realized for some reason, or arose in minds of the Europeans themselves. All these goals, identified in various official and unofficial European sources, mainly dating from the middle of the XIII century, are discussed here taking into account information from synchronous Eastern sources. Despite well-known ideas of a world-building monarchy, perhaps actually hatched by the Mongol khans, events in Europe suggest that their main goal there was to punish the Hungarian king Bela IV, who refused to hand over the Polovtsians hiding in Hungary to the Mongols.

Published: April 2021

Pasar untuk ban mobil terus tumbuh dan berkembang, karena hingga saat ini belum ada kendaraan massal yang bisa berjalan tanpa menggunakan ban, sehingga ban merupakan komponen utama dalam mobilisasi kendaraan. Semakin banyak jumlah mobil yang beredar, maka semakin banyak juga penjualan ban di pasar. Pemilihan strategi pemasaran pada industri ban harus memberikan efek yang cukup signifikan terhadap penjualan karena terkait dengan biaya yang dikeluarkan. Pada suatu kondisi tertentu jumlah biaya yang dikeluarkan untuk mengadakan aktifitas promosi maupun program loyalitas besarnya bisa mencapai 50 persen jika dibandingkan dengan net profit yang didapatkan. Berdasarkan penelitian terdapat perbedaan persepsi bauran pemasaran, penjualan kendaraan, dan program loyalitas yang dilakukan oleh merek ban ABC, XYZ, dan BCD. Pada merek ABC, persepsi produk merupakan variabel yang berpengaruh signifikan terhadap sikap sedangkan untuk merek XYZ dan BCD persepsi produk, harga, dan promosi berpengaruh signifikan terhadap sikap. Hal tersebut sama dengan hasil perhitungan SEM dengan menggabungkan tiga merek tersebut dengan hasil persepsi produk, harga, dan promosi berpengaruh signifikan hanya terhadap sikap. Hasil penelitian juga menunjukkan tidak terdapat pengaruh signifikan antara sikap terhadap pembelian.
Small-bowel obstruction due to excessive consumption of oleaster-leafed pear (Pyrus elaeagnifolia Pall.): A retrospective study
Authors: KARAISLI Serkan , Karayol Fatih
Published: April 2021

Background: Small-bowel obstruction (SBO) is a common emergency
worldwide and adhesions are the main cause. Oleaster-leafed pear (Pyrus
elaeagnifolia Pall.) is an endemic wild pear species in Anatolia. The
wild pear fruits are consumed for the treatment of diarrhea in
traditional medicine in Turkey. Here, we aimed to describe SBO caused by
excessive consumption of wild pear and compare clinical features of it
with those in adhesive SBO. Methods: The medical records of patients who
were followed with a diagnosis of SBO between May 2018 and September
2019 were reviewed. Patients with wild pear-related SBO (Group 1) and
patients with adhesive SBO (Group 2) were included in the study. Patient
characteristics, blood parameters and clinical features were compared.
Results: A total of 74 patients including 16 in Group 1 and 58 in group
2 were included. Amount of wild pear consumed was median 600 grammes
(range, 450-800 gr). The median age in Group 1 and Group 2 was 55 and
60.5, respectively. History of previous SBO was more common in Group 2
(p=0.032). Increased levels of WBC, CRP and BUN were significantly more
frequent in Group 2 (all p<0.05). Group 1 was associated with
a shorter duration of complaints and faster recovery (all
p<0.05). Surgical intervention was required for six patients
(10.3%) in only Group 2. Conclusion: The potential adverse effects of
over-consumed traditional medicines should be kept in mind. Questioning
the last food consumed before the complaints start may be a clue for
food-induced SBO.
