Aspects regarding the explosion risk assessment of installations in atmospheres with combustible dust
Authors: Popa Cătălin Mihai , Păun Florin Adrian , Gabor Dan Sorin 
Published: January 2022

Many industrial processes involving the presence of dust and combustible dust, suspended or accumulated in the form of deposits, have the potential to lead to a fire, explosion or decomposition in the presence of oxygen. As the damage caused by an explosion of dust is generally greater than that caused by explosions of flammable gases and vapours, a special attention must be paid to measures and means of protection and prevention of explosions of dust.
A dust explosion can only occur if there is mainly a potentially explosive atmosphere generated by the air / dust mixture and a source of ignition.
The level of safety is given by the operational efficiency of the employees and technical equipment involved in the production process to ensure that at least one of the above conditions is eliminated. The probability of a dust explosion is related to the physicochemical properties of the processed materials, together with the nature of the operations performed and the equipment used.
This paper highlights the principles and factors that must be taken into account when conducting an explosion risk assessment in installations with combustible dust atmospheres in order to establish prevention and protection measures, with the aim of ensuring a tolerable level of risk.
Application of flammability testing methods for conveyor belts intended for use in potentially explosive atmospheres in order to select suitable types for field application
Authors: Păun Florin Adrian , Gabor Dan 
Published: January 2022

The conveyor belts are widely used and can be found, for example, in the underground and surface mining industry as well as in other industries involving the transport of various products, materials, etc.
The need to ensure the transport of various products, materials, involves the use of conveyor belts in normal environments as well as in environments with a potentially explosive atmosphere.
When used in potentially explosive atmospheres, conveyor belts shall not be sources of ignition for the explosive atmospheres generated by gases, vapors, flammable mists and/or combustible dusts in the mixture with the air.
This involves the use of conveyor belts in a particular construction, compliance with the applicable essential safety and health requirements as well as granting a special attention to the identification/selection of types suitable for the specific field application.
The purpose of the paper is to highlight the importance of testing by accredited laboratory tests, the flammability properties of conveyor belts intended for use in potentially explosive atmospheres, in order to easily identify/select, by end users, the types of conveyor belts adequate for specific application.
Communication in Healthcare: Global challenges in the 21st Century
Authors: Etheredge Harriet Rosanne , Fabian June 
Published: January 2022

AbstractThis article explores the communication challenges brought about by the digital revolution in the 21st century for healthcare professionals internationally. It particularly focuses on the use of content-generating and sharing platforms like social media. Globally, healthcare has been irrevocably altered by digital innovation and health professionals deploy an extensive range of social media and web-based tools on a daily basis. However, many healthcare professionals use these platforms in a regulatory vacuum—where there may not be specific legal or ethical guidance—and without an appreciation of the associated risks. Given the special protections afforded to the practitioner–patient relationship, and the importance of a health practitioners' reputation, it is vital that we understand how to traverse the many ethical and legal challenges of the digital interaction. A comprehensive set of recommendations (see “Guidelines for Good Digital Citizenship in the Health Professions” on page 5 ff.) to keep practitioners out of trouble is provided. These hinge on the notion of being a “good person and a good doctor” as a formative maxim for ethical and legal safety. The constituents of publication, and the consequences of falling foul of acceptable publication standards on social media, are specifically discussed. “Publication” involves sharing content with a third party, or a group of people, and social media refers to platforms on which content can be shared with more than one person. Hence, most information that we post on social media can be considered as “published,” and as such may attach liability for health professionals who do not use these platforms with requisite care and sufficient forethought.

AbstractParagangliomas of the cauda equina are tumors of rare incidence, with ~ 220 cases described in the world literature. They are benign lesions, grade I by the World Health Organization (WHO), whose definitive diagnosis can only be made by immunohistochemical analysis. Its neuroendocrine nature is evidenced by the presence of chromogranin. The relevance of reporting this case is because paragangliomas of the cauda equina should be included among the differential diagnoses of intradural and extramedullary tumors, and especially because they can cause perioperative and intraoperative hypertensive crises by adrenergic discharge.The present study presents the case of a 36-year-old male patient diagnosed with a lumbar spine tumor located in the central spinal canal that presented as cauda equina syndrome involving 4 months of bilateral sciatica, paraparesis, urinary and fecal retention. The diagnosis of paraganglioma was confirmed by immunohistochemical positivity for chromogranin after microsurgical resection of the tumor.
Effectiveness of Structured Counseling and Preventive Strategies in Promoting Awareness and Expressed Habitual Practices Toward Prevention of Urinary Tract Infection Among Women of Reproductive Age Group: A Pilot Study
Authors: Sequera Sonia Karen Liz , Chacko Leena Kunnath 
Published: January 2022

Abstract
Objectives Urinary tract infection (UTI) is the most common infection that affects half of all women in their lifetime and one-fourth have recurrent infections. Health behaviors could prevent the recurrence of UTIs and therefore motivation and increasing awareness are necessary for healthy behavior change. This study was done to evaluate the effectiveness of structured counseling and preventive strategies (SCAPS) in promoting awareness and expressed habitual practices among the women of the reproductive age group to prevent UTI.
Materials and Methods Block randomization with multiple interventions and follow-up were conducted among 60 women (30 in each group, randomly assigned using the SNOSE technique) attending the OBG and urology OPDs of a selected medical college hospital. Purposive sampling was used to select the subjects. Women who were positive for urine culture and experiencing typical symptoms of UTI, as assessed using the symptom score checklist, were recruited for the study. Pre-test awareness was assessed using a structured awareness questionnaire and a rating scale for expressed habitual practice. After the pre-test, on the same day, the experimental group received SCAPS intervention followed by a second session during the third month. At the third (before the second session) and the sixth-month post-tests were conducted by delivering the same tool to determine the post-test level of awareness and expressed habitual practice after the administration of SCAPS.
Results The study shows there is a significant difference in the awareness and expressed habitual practice values in the experimental group (p < 0.005). The effectiveness of SCAPS showed that the mean ± standard deviation (SD) pre-test score of women (awareness - x̄1 ± SD = 9.47 ± 2.57, hygienic habitual practice - x̄1 ± SD = 20.93 ± 1.91, fluid and dietary practice - x̄1 ± SD = 7.73 ± 2.18 and sexual habits - x̄1 ± SD= 8.00 ± 3.33) was significantly lower than the mean ± SD post-test scores (awareness - x̄2 ± SD =11.37 ± 1.65, awareness - x̄3 ± SD = 12.00 ± 1.05), (hygienic habitual practice - x̄2 ± SD = 22.57 ± 2.16, x̄3 ± SD = 23.90 ± 1.99), (fluid and dietary practice - x̄2 ± SD = 10.07 ± 2.21, x̄3 ± SD =11.97 ± 1.79) and (sexual habits - x̄2 ± SD = 8.81 ± 2.51, x̄3 ± SD =9.81 ± 2.26).
Conclusion SCAPS was found to be effective on awareness and preventive habitual practices with regard to UTI. SCAPS can be recommended for vulnerable groups such as females so that UTI could be prevented.

SWI/SNF-Related SMARCA2 Gene Mutation Associated with Nicolaides–Baraitser's Syndrome: Follow-up Study
Authors: Akella Radharamadevi 
Published: January 2022

AbstractNicolaides–Baraitser's syndrome is a rare, dominantly inherited well-delineated syndrome caused by mutations in the SMARCA2 gene which is located on the small arm of chromosome 9. In this study, a de novo missense variant, which was identified in a 3-year-old boy by whole exome sequencing is reported. The de novo heterozygous V1198M missense variant in SMARCA2 gene in exon 25 is novel. Identifying the condition is crucial for the long-term management and family counseling. Follow-up over 4 years revealed improvements in overall performance.
Is It Possible to Perform Fifth Carpometacarpal Joint Arthroscopy? Cadaveric Study on Its Feasibility, Safety, and Potential Hazards in Portal Creation
Authors: Koo Siu Cheong Jeffrey Justin , Pang Henry , Ho Pak Cheong 
Published: January 2022

Abstract
Background Fifth carpometacarpal joint (CMCJ) fracture dislocation is a relatively rare injury and most will require operative treatment because of its unstable nature. Improper reduction and fixation lead to joint surface destruction, pain, and reduced grasping power. Intra-articular fragment reduction is often obscured by dorsally displaced ulnar fragment. Therefore, fifth CMCJ arthroscopy can be advantageous in assisting intra-articular fragment reduction. However, there is no detailed description of the portal landmarks or portals' relationship with adjacent important structures in the literature.
Purposes To explore the feasibility and safety of fifth CMCJ arthroscopy, locations of the portals are examined in cadaveric hand specimens. Their proximity to important anatomical structures such as dorsal cutaneous branch of ulnar nerve (DCBUN), ring finger and little finger extensor digitorum communis (EDC), and extensor digiti minimi (EDM) is measured.
Methods Fifth CMCJ arthroscopy is performed on 11 cadaveric hand specimens by specialist-level surgeon. The portals are marked and portal positions are further confirmed under the fluoroscopy. Then the cadaveric specimens were undergone anatomical dissection by specialist-level surgeon. During dissection, the spatial relationship between the portal positions and DCBUN, EDC to ring finger and little finger, and EDM is identified. The distance between the portals and the above important structures was measured in millimeters.
Results DCBUN was consistently found between fourth metacarpohamate (4-MH) and fifth metacarpohamate (5-MH) portals, with it being closer to the latter (mean distance, 2.03 mm; range, 0–4.43 mm; standard deviation [SD], 1.09 mm). The closest tendon for 4-MH portal is ring finger EDC (mean distance, 2.65 mm; range, 0–5.89 mm; SD, 1.78 mm), while 5-MH portal and accessory portal were closest to EDC (mean distance, 1.88 mm; range, 0–3.69 mm; SD, 1.25 mm) and EDM (mean distance, 7.79 mm; range, 6.63–10.72 mm; SD, 1.49 mm), respectively. During the process of specimen dissection, we found no damage to the above structures after portal introduction.
Conclusion The above findings support the use of fifth CMCJ arthroscopy, which can be used for assisted reduction in fifth metacarpal base fracture dislocation and hamate body fracture. Gentle soft tissue spreading technique during portal creation prevents injury to the important structure surrounding the portals.
Level of evidence This is a Level V study.

Abstract
Objective Natural language processing (NLP) systems convert unstructured text into analyzable data. Here, we describe the performance measures of NLP to capture granular details on nodules from thyroid ultrasound (US) reports and reveal critical issues with reporting language.
Methods We iteratively developed NLP tools using clinical Text Analysis and Knowledge Extraction System (cTAKES) and thyroid US reports from 2007 to 2013. We incorporated nine nodule features for NLP extraction. Next, we evaluated the precision, recall, and accuracy of our NLP tools using a separate set of US reports from an academic medical center (A) and a regional health care system (B) during the same period. Two physicians manually annotated each test-set report. A third physician then adjudicated discrepancies. The adjudicated “gold standard” was then used to evaluate NLP performance on the test-set.
Results A total of 243 thyroid US reports contained 6,405 data elements. Inter-annotator agreement for all elements was 91.3%. Compared with the gold standard, overall recall of the NLP tool was 90%. NLP recall for thyroid lobe or isthmus characteristics was: laterality 96% and size 95%. NLP accuracy for nodule characteristics was: laterality 92%, size 92%, calcifications 76%, vascularity 65%, echogenicity 62%, contents 76%, and borders 40%. NLP recall for presence or absence of lymphadenopathy was 61%. Reporting style accounted for 18% errors. For example, the word “heterogeneous” interchangeably referred to nodule contents or echogenicity. While nodule dimensions and laterality were often described, US reports only described contents, echogenicity, vascularity, calcifications, borders, and lymphadenopathy, 46, 41, 17, 15, 9, and 41% of the time, respectively. Most nodule characteristics were equally likely to be described at hospital A compared with hospital B.
Conclusions NLP can automate extraction of critical information from thyroid US reports. However, ambiguous and incomplete reporting language hinders performance of NLP systems regardless of institutional setting. Standardized or synoptic thyroid US reports could improve NLP performance.
Echoes of Empire: racism and historical amnesia in the British media coverage of migration
Authors: Połońska-Kimunguyi Ewa 
Published: January 2022

AbstractThis paper looks at how the British media addressed the issue of migration in Europe between 2015 and 2018, four years when the topic was high on news and political agendas, due to the so-called ‘refugee crisis’ and the UK’s debate on Britain’s relationship with the European Union and free movement of people. Based on a sample of 400 articles from two national newspapers, The Guardian and The Times, the paper compares the content and discourse between the left-wing and right-wing press. The paper argues that media representations turn refugees into ‘migrants’ and portray them as either a threat to the national economy and security or as passive victims of distant circumstances. The study historicizes these media narratives and reveals that the discourse they employ advances the racialised mix of knowledge and historical amnesia and reproduces the age-old hierarchies of the colonial system which divided humans into superior and inferior species. Migrant voice is largely missing from the coverage. History, that could explain the causes of ‘migration’, the distant conflicts and Britain’s role in them, is also nowhere to be found. The paper considers the exclusion of history and migrant voices from stories told to the British audience and reflects on their domestic and international implications.

Published: January 2022

Context There is a large gap between developed and developing countries in the field of genetic evaluation of livestock animals. Introduction of genomic evaluation procedures and methods could contribute to reducing this gap. Aims The goal of this study was to select a reference cow population for the Holstein breed in Tunisia. Specific objectives were to update adjustments for non-genetic factors affecting milk yield, estimate genetic parameters for milk yield, and predict cow breeding values. Methods A BLUP animal model was used for 11 175 lactations recorded between 2012 and 2017 from 6251 dairy cattle raised in 33 Holstein dairy herds from three types of herds or production sectors. A pedigree file of 16 211 males and females was included in the genetic evaluation. Multiplicative adjustment factors were computed for age and month of calving, using adjusted 305 days in milk. Key results Month of calving, age at calving and farm ownership were significant sources of variation for milk yield. Cows calving in autumn and early winter (September–January) yielded more milk than those calving in spring (February–May) by 430 kg, and summer (June–August) by 455 kg. Holstein cows in Tunisia reached their maximum milk yield during the fourth lactation. Average adjusted milk yield for days in milk, month and age of calving was 6621 ± 2883 kg. Heritability estimates of adjusted milk yield were 0.14 ± 0.02 for all seven lactations and 0.16 ± 0.03 for the three first lactations. Phenotypic correlations among lactations were all positive, ranging from 0.25 to 0.43. On the basis of two main traditional designs (extreme yield and top accuracy), 1000 cows were selected to form the Tunisian female reference population. Conclusion The first step of genomic evaluation has been realised by forming a reference population from cows selected for adjusted milk yield production, based on their predicted breeding values and accuracies, using a BLUP animal model. Implication In the absence of progeny testing and sufficient proven sires, a cow reference population could represent the alternative for implementing genomic selection in developing countries.

Published: January 2022

Significance
The manipulation of liquid droplets plays a crucial role in multidisciplinary applications. However, existing methods still face many challenges, such as short distance, low velocity, restricted operating conditions, the need for extra responsive additives in droplet, and so on. To circumvent these constraints, here we develop a droplet electrostatic tweezer to trap the liquid droplet or faithfully guide the droplet motion in a remote manner. Our method allows high flexibility and precision in manipulating droplets of different types, volumes, and numbers under different working conditions, such as in open and closed spaces and on flat and tilted surfaces as well as in oil medium, imparting various applications, such as high-throughput and high-sensitivity Raman detection.
Estimating the memory parameter for potentially non-linear and non-Gaussian time series with wavelets
Authors: Xu Chen , Zhang Ye 
Published: January 2022

Abstract
The asymptotic theory for the memory-parameter estimator constructed from the log-regression with wavelets is incomplete for 1/f processes that are not necessarily Gaussian or linear. Having a complete version of this theory is necessary because of the importance of non-Gaussian and non-linear long-memory models in describing financial time series. To bridge this gap, we prove that, under some mild assumptions, a newly designed memory estimator, named LRMW in this paper, is asymptotically consistent. The performances of LRMW in three simulated long-memory processes indicate the efficiency of this new estimator.

Abstract
The ultraviolet (UV)-induced dissociation and photofragmentation of gas-phase CH2BrI molecules induced by intense femtosecond extreme ultraviolet (XUV) pulses at three different photon energies are studied by multi-mass ion imaging. Using a UV-pump–XUV-probe scheme, charge transfer between highly charged iodine ions and neutral CH2Br radicals produced by C–I bond cleavage is investigated. In earlier charge-transfer studies, the center of mass of the molecules was located along the axis of the bond cleaved by the pump pulse. In the present case of CH2BrI, this is not the case, thus inducing a rotation of the fragment. We discuss the influence of the rotation on the charge transfer process using a classical over-the-barrier model. Our modeling suggests that, despite the fact that the dissociation is slower due to the rotational excitation, the critical interatomic distance for charge transfer is reached faster. Furthermore, we suggest that charge transfer during molecular fragmentation may be modulated in a complex way.
Effect of atmospheric-pressure plasma irradiation on the surface tension of water
Authors: Shirai Naoki , Kaneko Takuma , Takamura Yuto , Sasaki Koichi 
Published: January 2022

Abstract
We have shown that measuring the surface tension is a useful scheme to examine the plasma–liquid interface in real-time. The surface tension was measured using a method based on the dispersion relation of an acoustic capillary wave excited on the water surface. The surface tension gradually increased with time, when the water surface was irradiated with the outside region of the spatial afterglow of an atmospheric-pressure plasma. The Marangoni effect associated with the localized increase in the surface tension was observed during the plasma irradiation. The surface tension decreased after the termination of the discharge. A correlation was found between the transient decrease in the surface tension and the variation of the OH radical density in the gas phase. No increase in the surface tension was observed in the solution containing a trapping agent for liquid-phase OH radicals. These experimental results suggest that OH radicals act to increase the surface tension. However, the behavior of the surface tension cannot be explained perfectly by considering only the action of OH radicals.
