Hiatal hernia of the adult is a benign pathology of the abdominal esophagus and has an increasing incidence because of the association with obesity. Hiatal hernia becomes clinical manifest when it presents gastroesophageal reflux disease, when it is voluminous or is incarcerated. If for gastroesophageal reflux disease there is an endoscopic treatment, for hiatal hernia the treatment is purely surgical. Open or laparoscopic, the objectives of the surgical treatment are the same as for any abdominal hernia. The local anatomy plays an important role for fulfilling the objectives. This study provides a detailed description of the regional anatomy of the gastroesophageal junction and of the esophageal hiatus of the diaphragm based on the laparoscopic procedures performed in the Emergency Clinical Hospital of Bucharest. There were evaluated the aspects and the relations of the anatomical structures and also the consistency (because the manipulation and traction is made with the help of the instruments). In conclusion, a deep understanding of the regional anatomy and variations facilitates a safe laparoscopic dissection of diaphragmatic hiatus and abdominal esophagus and helps the surgeon to avoid intraoperative accidents.

Published: September 2021

Currently, the spleen is considered the main peripheral immune organ. Infections are the most important consequences of the absence of spleen and may evolve to severe sepsis (OPSI = Overwhelming Post Splenectomy Infection) and death. Therefore, in the context of trauma and not only, spleen conservation or autologous spleen implant are required to prevent postsplenectomy infections. In addition, patients require immunoprophylaxis (Pneumococcal Vaccination Haemophilus influenzae type b and Meningococcal vaccination) and chemoprophylaxis (penicillin V/amoxicillin).
Optimized Sliding Mode Control of Three-Phase Four-Switch Inverter BLDC Motor Drive Using LFD Algorithm
Authors: Kadhim Quasy , Abbas Abbas , Ezzaldean Mohammed
Published: September 2021

This paper presents a low-cost Brushless DC (BLDC) motor drive system with fewer switches. BLDC motors are widely utilized in variable speed drives and industrial applications due to their high efficiency, high power factor, high torque, low maintenance, and ease of control. The proposed control strategy for robust speed control is dependent on two feedback signals which are speed sensor loop which is regulated by Sliding Mode Controller (SMC) and current sensor loop which is regulated by Proportional-Integral (PI) for boosting the drive system adaptability. In this work, the BLDC motor is driven by a four-switch three-phase inverter emulating a three-phase six switch inverter, to reduce switching losses with a low complex control strategy. In order to reach a robust performance of the proposed control strategy, the Lévy Flight Distribution (LFD) technique is used to tune the gains of PI and SMC parameters. The Integral Time Absolute Error (ITAE) is used as a fitness function. The simulation results show the SMC with LFD technique has superiority over conventional SMC and optimization PI controller in terms of fast-tracking to the desired value, reduction speed error to the zero value, and low overshoot under sudden change conditions.

Published: September 2021

This paper aims to present the numerical study of a dusty micropolar fluid due to a stretching sheet with constant wall temperature. Using the suitable similarity transformation, the governing partial differential equations for two-phase flows of the fluid and the dust particles are reduced to the form of ordinary differential equations. The ordinary differential equations are then numerically analysed using the bvp4c function in the Matlab software. The validity of present numerical results was checked by comparing them with the previous study. The results graphically show the numerical solutions of velocity, temperature and microrotation distributions for several values of the material parameter K, fluid-particle interaction parameter and Prandtl number for both fluid and dust phase. The effect of microrotation is investigated and analysed as well. It is found that the distributions are significantly influenced by the investigated parameters for both phases.

Published: September 2021

In the firm belief that the world needs green, renewable and more efficient energy resources, the present paper is concerned with developing a new design for horizontal-axis wind-turbine (HAWT) blades. The flower of Nelumbo nucifera (Sacred Lotus) was the motive for the present design of a three-blade wind turbine. Nelumbo Nucifera flower has an aerodynamically appropriate structure, which qualifies the flower to be the nature-inspiration for the present research. A computational fluid dynamics (CFD) simulation was applied in order to ensure the ability and eligibility of the proposed solution and estimate real world's results. The performance of the blade airfoil can be improved by applying the Lotus flower's structural design and modifying the blade straightening. The experimental findings demonstrated performance enhancement by 31.7% compared to NACA 2412 airfoil.
Analytical Solution of Unsteady Casson Fluid Flow Through a Vertical Cylinder with Slip Velocity Effect
Authors: Wan Faezah Wan Azmi  , Ahmad Qushairi Mohamad  , Lim Yeou Jiann  , Sharidan Shafie
Published: September 2021

Casson fluid is a non-Newtonian fluid with its unique fluid behaviour because it behaves like an elastic solid or liquid at a certain condition. Recently, there are several studies on unsteady Casson fluid flow through a cylindrical tube have been done by some researchers because it is related with the real-life applications such as blood flow in vessel tube, chemical and oil flow in pipelines and others. Therefore, the main purpose of the present study is to obtain analytical solutions for unsteady flow of Casson fluid pass through a cylinder with slip velocity effect at the boundary condition. Dimensional governing equations are converted into dimensionless forms by using the appropriate dimensionless variables. Dimensionless parameters are obtained through dimensionless process such as Casson fluid parameters. Then, the dimensionless equations of velocity with the associated initial and boundary conditions are solved by using Laplace transform with respect to time variable and finite Hankel transform of zero order with respect to the radial coordinate. Analytical solutions of velocity profile are obtained. The obtained analytical result for velocity is plotted graphically by using Maple software. Based on the obtained result, it can be observed that increasing in Casson parameter, time and slip velocity will lead to increment in fluid velocity. Lastly, Newtonian fluid velocity is uniform from the boundary to the center of cylinder while Casson fluid velocity is decreased when approaching to the center of cylinder. The present result is validated when the obtained analytical solution of velocity is compared with published result and found in a good agreement.

ON COMPACT 4TH ORDER FINITE-DIFFERENCE SCHEMES FOR THE WAVE EQUATION
Authors: Zlotnik Alexander , Kireeva Olga
Published: September 2021

We consider compact finite-difference schemes of the 4th approximation order for an initial-boundary value problem (IBVP) for the n-dimensional nonhomogeneous wave equation, n≥ 1. Their construction is accomplished by both the classical Numerov approach and alternative technique based on averaging of the equation, together with further necessary improvements of the arising scheme for n≥ 2. The alternative technique is applicable to other types of PDEs including parabolic and time-dependent Schro¨dinger ones. The schemes are implicit and three-point in each spatial direction and time and include a scheme with a splitting operator for n≥ 2. For n = 1 and the mesh on characteristics, the 4th order scheme becomes explicit and close to an exact four-point scheme. We present a conditional stability theorem covering the cases of stability in strong and weak energy norms with respect to both initial functions and free term in the equation. Its corollary ensures the 4th order error bound in the case of smooth solutions to the IBVP. The main schemes are generalized for non-uniform rectangular meshes. We also give results of numerical experiments showing the sensitive dependence of the error orders in three norms on the weak smoothness order of the initial functions and free term and essential advantages over the 2nd approximation order schemes in the non-smooth case as well.

Introduction: Information on the clinical characteristics of local patients with confirmed COVID-19 is limited. This study aims to report the clinical characteristics of 147 patients admitted and receiving treatment at a teaching hospital.

Methodology: Patients’ socio-demographic and epidemiological data, clinical features, laboratory findings and clinical outcomes were extracted using a data sheet.

Results: The median patient age was 25 [interquartile range (IQR)] 20–44) years, and most of patients were male (68.7%) and of Malaysian nationality (88.4%). Almost half of the patients were from a case cluster related to a religious event (48.3%) and 12.9% had a history of overseas travel. A total of 33.3% of patients were not related to any case cluster, i.e. sporadic cases. Radiological investigation showed that 13.6% of the patients had chest X-ray changes and all laboratory parameters were within the normal ranges. Sixty-six patients (44.9%) experienced symptoms. The most common symptoms were rhinitis (66.7%), followed by fever (19.7%) and cough (15.2%). Age, gender, case cluster, comorbidity status, haemoglobin, albumin, total protein, bilirubin total and alkaline phosphatase level were associated with symptomatic status.

Conclusions: In this single-centre study, COVID-19 infection led not only to case clusters, but also to sporadic infections, with patients being either symptomatic or asymptomatic. These sporadic cases and asymptomatic patients may hamper effective contact tracing, leading to rapid human-to-human transmission in our population. Future studies on the prevalence and clinical significance of asymptomatic and presymptomatic COVID-19 patients would pre-emptively address issues on further containment of the pandemic.

Authors: Anandita Nanda Wahyu , Nurdiana Nurdiana , Wahyuni Endang Sri , Sujuti Hidayat
Published: September 2021

AIM: This study aims to investigate the concentration of cyclic adenosine monophosphate (cAMP), inositol 1,4,5-trisphosphate (IP3), calcium (Ca2+), and the expression phosphorylated myosin light chain (MLC) in Rattus norvegicus scleral fibroblast cells.

METHODOLOGY: This study utilized an in vitro experimental study by applying Rattus norvegicus scleral fibroblast cell culture. The cultured cells were divided into control and lens-induced myopia (LIM) groups. The control and LIM culture groups were each divided into five groups, namely, negative control, 0.1 μM acetylcholine, 0.1 μM himbacine, 0.1 μM methoctramine, and 0.1 μM 4-DAMP group. The cAMP, IP3, and Ca2+ concentration were analyzed in the 0th, 5th, 10th, 20th, and 30th. The phosphorylated MLC expression was analyzed using confocal microscope.

RESULTS: In the LIM group, the highest cAMP concentration is visible at the 10th min on the himbacine group (0.304 ± 0; p = 0.043) and on the 4-DAMP group (0.346 ± 0; p = 0.043). The highest IP3 concentration is found on the LIM group at the 20th min in comparison to the control group (2503.6 ± 11 vs. 2039.2 ± 2.1; p = 0.046). The highest Ca2+ concentration belongs to the 4-DAMP treatment group from the 5th to the 30th min. The highest average phosphorylated MLC expression value in the LIM group is shown by the 0.1μM 4-DAMP treatment (184.2 ± 37.9c au).

CONCLUSION: The regulation of cAMP, IP3, Ca2+, and phosphorylated MLC on the M2 and M3 muscarinic receptor of the scleral fibroblast cells of myopia animal models differs from normal animal models which may be due to interactions of M2 and M3 muscarinic receptor as compensation reaction or crosstalk on myopia induction.

The Pattern of Temporary International Migration in Sri Lanka
Authors: Dissanayake Lakshman , Samarakoon Irangi
Published: September 2021

This study differs from earlier studies by using terminology which defines temporary international migration as those who were abroad more than six months at the time of the investigation for purpose other than permanent residence. This includes not only the labour migrants but also other categories such as those who have gone for educational purposes. One of the most noticeable features is the dominance of estate sector women compared to other sectors because a higher percentage of estate women has gone abroad temporarily compared to women in urban and rural sectors. The study also suggests that one of the push factors for temporary international migration seeking employment as the differences in poverty levels in urban, rural and estate sectors. Furthermore, it was found that more younger women in the estate sector who are in the labour force ages move abroad for employment. It was revealed from the analysis that the districts which show a higher level of migration for employment, also exhibit a higher level of migration for education compared to less mobility districts. This means that there is a clear distinction between migrant districts and non-migrant districts irrespective of reasons for migration. Districts in the North-east Sri Lanka seem to be less mobile both locally and internationally. This can be due to the disruption that occurred in those districts as a result of 30-year long civil war which was concluded in 2009. However, one can predict that they also will follow a general pattern of international migration. It was observed that the majority moved to Middle East Countries for employment and a significant number were travelling to OECD countries for higher education.

Published: September 2021

Parkinson’s disease (PD) is the second most common age-related neurodegenerative disorder and is characterized by the formation of cellular inclusions inside neurons that are rich in an abnormal form of the protein α-synuclein (α-syn). Microglia are the CNS resident immune cells that react to misfolded proteins through pattern recognition receptor ligation and activation of signaling transduction pathways. Here, we studied activation of primary microglia isolated from wild-type mouse by distinct α-syn forms and their clearance. Internalization of α-syn monomers and oligomers efficiently activated the NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome via TLR2 and TLR5 ligation, thereby acting on different signaling checkpoints. We found that primary microglia effectively engulf α-syn but hesitate in its degradation. NLRP3 inhibition by the selective inhibitor CRID3 sodium salt and NLRP3 deficiency improved the overall clearance of α-syn oligomers. Together, these data show that distinct α-syn forms exert different microglial NLRP3 inflammasome activation properties, thereby compromising its degradation, which can be prevented by NLRP3 inhibition.

Parasite-specific CD8 T cell responses play a key role in mediating immunity against Theileria parva in cattle (Bos taurus), and there is evidence that efficient induction of these responses requires CD4 T cell responses. However, information on the antigenic specificity of the CD4 T cell response is lacking. The current study used a high-throughput system for Ag identification using CD4 T cells from immune animals to screen a library of ∼40,000 synthetic peptides representing 499 T. parva gene products. Use of CD4 T cells from 12 immune cattle, representing 12 MHC class II types, identified 26 Ags. Unlike CD8 T cell responses, which are focused on a few dominant Ags, multiple Ags were recognized by CD4 T cell responses of individual animals. The Ags had diverse properties, but included proteins encoded by two multimember gene families: five haloacid dehalogenases and five subtelomere-encoded variable secreted proteins. Most Ags had predicted signal peptides and/or were encoded by abundantly transcribed genes, but neither parameter on their own was reliable for predicting antigenicity. Mapping of the epitopes confirmed presentation by DR or DQ class II alleles and comparison of available T. parva genome sequences demonstrated that they included both conserved and polymorphic epitopes. Immunization of animals with vaccine vectors expressing two of the Ags demonstrated induction of CD4 T cell responses capable of recognizing parasitized cells. The results of this study provide detailed insight into the CD4 T cell responses induced by T. parva and identify Ags suitable for use in vaccine development.

Trivial Objects from Taishō Japan in the Collection of Alma M. Karlin
Authors: Shigemori Bučar Chikako
Published: September 2021

Alma M. Karlin, a young woman adventurer who made her journey around the world between 1919 and 1927, stayed in Japan for a little more than a year. As a young woman without significant funds, she relied on her own ability to earn a living during her stay in the country. Among the items she brought back from Japan to Slovenia there are many small objects which are not typical “exotic objects from the Far East”. They are rather small and trivial items such as a wall calendar, a streetcar ticket, children’s miniature toys, a part of ceremonial wrappings, and paper bookmarks. This paper focuses on the small and untypical items Karlin brought back from Japan. Karlin’s travelogue and other writings, including her notes on the unused postcards, give us some information about her life in Japan. Together with her travelogue, notes and messages on the objects in her legacy, we can reconstruct some aspects of her everyday life in Japan. Though small and trivial, such items collected by Karlin reveal some important details of her experience in the central part of Tokyo in the Taishō period.
The Allure of the Mystical
Authors: Veselič Maja
Published: September 2021

Alma M. Karlin (1889–1950), a world traveller and German-language travel and fiction writer, cultivated a keen interest in religious beliefs and practices of the places she visited, believing in the Romantic notion of religion as the distilled soul of nations as well as in the Theosophical presumption that all religions are just particular iterations of an underlying universal truth. For this reason, the topic of religion was central to both her personal and professional identity as an explorer and writer. This article examines her attitudes to East Asian religio-philosophical traditions, by focusing on the two versions of her unpublished manuscript Glaube und Aberglaube im Fernen Osten, which presents an attempt to turn her successful travel writing into an ethnographic text. The content and discourse analyses demonstrate the influence of both comparative religious studies of the late 19th century, and of the newer ethnological approaches from the turn of the century. On the one hand, Karlin adopts the binary opposition of religion (represented by Buddhism, Shintoism, Daoism and Confucianism) or the somewhat more broadly conceived belief, and superstition (e.g. wondering ghosts, fox fairies), and assumes the purity of textual traditions over the lived practices. At the same time, she is fascinated by what she perceives as more mystical beliefs and practices, which she finds creatively inspiring as well as marketable subjects of her writing.

The COVID-19 has become a major threat to Pakistan and worldwide, and has become a significant issue for global health, economy and societies. This rapid spread was occurred from Wuhan, China to most of the part of the world. To elaborate the concept and recommendations regarding the safety precautions in operation theater (O.T) and inside associated team during the current scenario of COVID-19. Many research and review articles were studied to collect information about Covid-19 and strategies published in various journals using the search engine, PubMed and Medline. The COVID-19 has significantly changed all aspects of daily life around the world since very start of this year 2020. SARS-CoV-2 (COVID-19), a novel corona virus, has been infected many healthcare workers. In this perspective, hospitals need a strategy to manage their resources, staff and supplies so that patients receive optimal treatment. A decision tree algorithm was developed that defined the recommendations for safety measures in operation theater and operating procedures, these include identifying and developing an isolation room, administrative measures such as transformations in working flow and procedures, introducing personal protective equipment for the employees and formulating anesthetic clinical guidelines. These control actions are essential to enhance the excellence of care provided to COVID-19 patients and to minimize the risk of spread to other patients or staff. The operating room is a dynamic environment with numerous staff like anesthesiologists, physicians, nurses, O.T attendants and technicians; however, we agree that the containment steps are important in order to improve the standard of treatment provided to COVID-19 patients and to minimize the chance of viral spread to patients other than COVID-19 and hospital staff.

INTRODUCTION: Bacteremia, is regarded as a significant reason in all over the world for morbidity and mortality in mainly sick patients. Invasion by microorganisms in blood constitutes the critical issues in infectious disease. The aims and objectives are to find out the pathogenic agents infecting males and females in blood of different age groups and naturally used antimicrobial sensitivity profiles. METHODS: All the blood samples were collected aseptically and tested in Popular Diagnostic Centre, Dhaka, Bangladesh between May, 2020 and October, 2020. Total 305 blood specimens from both sexes of different age groups were collected. Cultural analysis was performed by Gram staining, phenotypic examination, biochemical and serological analysis. Finally, antibiotic susceptibility test was done against commonly used antibiotics. RESULTS: 96 (31.47%) samples yielded a positive culture with predominant isolate being Salmonella typhi (41.66%)  though Salmonella spp., Salmonella typhi, Staphylococcus spp and Pseudomonas spp. were also detected. Like most of previous reports, Salmonella spp was predominant, this corroborates this study. But the profile of antimicrobial susceptibility of the detected organisms varied comparing studies which were done in the past. The isolates were found mostly resistant to nalidixic acid. Most of the pathogens showed tremendous susceptibility against ceftriaxone, cefixime, ceftazidime etc.
CONCLUSION: The antibiotic selection for the treatment of bacteraemia in patients should always be serious concern due to multidrug resistant (MRD) bacterial isolates. For proper treatment of anti-bacterial resistance and critical mortality and morbidity should be related with the sickness. For validating more reliability, this research requires further work.

Published: September 2021

BACKGROUND: Diabetes mellitus (DM) is a chronic metabolic syndrome marked by hyperglycemia due to absolute or relative deficiency of insulin hormone. Diabetic neuropathy is a complication of both type 1 and type 2 diabetes. Although pain is one of the most dominant symptoms of diabetic neuropathy, its pathophysiological mechanisms yet unknown. Toxic effects of high glucose levels play an important role in the development of this complication.
METHODOLOGY: Data was collected through the questionnaire regarding Clinical findings, medical records, weight, age, family history, different habits, and psychogenic behavior. All the patients with the mentioned diseases are included in this study, excluding the mentally ill patients and the pregnant women.
RESULT:  The result of the present study showed that diabetic neuropathy is the most common complication of diabetes mellitus. It has been observed that most of the patients due to lack of awareness are suspected to the elevated or extreme blood sugar level which leads to neuropathy. Due to the Diabetic Peripheral Neuropathy (DPN) most of the patients suffering from foot problems, foot ulcers and then amputations. Lack of awareness, lack of health management, obesity, blood pressure changes, less care plays a key role in increasing the chances of diabetic neuropathy. COCLUSION: Diabetic neuropathy had very bad influence on a person’s health and daily activities. The Patient education programs need to emphasize on large scale. The ultimate aim of this study is the foot care education for people with the diabetes and to prevent foot ulcers and amputation.

Buckling Analysis of Cantilever Laminated Hybrid Composite Plates using Finite Element and Statistical Methods
Authors: EVRAN Savaş
Published: September 2021

In this study, the critical buckling load of hybrid composite plates with three layers was analyzed using numerical and statistical methods. Laminated hybrid composite plates were designed using glass-epoxy, boron-epoxy, carbon-epoxy, and metal. The outermost layers of the plates were modelled using fiber reinforced composite materials whereas the innermost layer of plates was created using Aluminum material (Al2024-T3). Numerical buckling behavior was calculated using finite element software ANSYS. Analysis of signal-to-noise ratio was utilized to decide the effects and optimal levels of the plates and their fiber orientation angles on buckling load. Analysis of variance at the 95 % confidence level was employed to indicate the control factors which have significant effect on the buckling responses.
Health Literacy and Health Outcomes of Adults in the United States: Implications for Providers
Authors: McDonald Marilyn , Shenkman Laura
Published: September 2021

The purpose of this paper is to explore health literacy of adults in the United States and review health outcomes as well as provider implications. Limited health literacy is a serious problem in the United States. Approximately 80 million adults in the United States have limited health literacy, which can adversely affect the quality of their health care. Poor health outcomes are associated with being health illiterate. Evidence shows that limited health literacy is associated with more hospitalizations; greater use of emergency care; lower receipt of mammography screening and influenza vaccine; poorer ability to demonstrate taking medications properly; poorer ability to interpret drug labels and health messages; and, among elderly persons, poorer overall health status and higher mortality rates. Health literacy is essential for patients to be able to take control and manage their own health. The benefits of being health literate include greater patient safety, less hospitalizations, a greater ability to care for oneself, and a greater cost savings to the healthcare system. This paper emphasizes “best practices” recommended by the World Health Organization (WHO),1 The American Medical Association (AMA),2 the Institute of Medicine (IOM),3 the Center for Disease Control (CDC),4 and the Joint Commission (JCAHO) 5 When patients, providers and communities work together to understand and improve health literacy a greater quality of life will result. Today’s health care providers are in a position to make an impact on the health illiteracy epidemic and improve the patient’s understanding about their health and outcomes.

Purpose: This paper reviewed literature regarding the utility and direction of reflective approaches in Medical imaging education. Methods: The Scopus database was accessed. The word “Reflective” was used as the main search term to look for the relevant literature. The inclusion criteria used in this study comprised of those papers published in English between the years 2006 to 2016, indexed in Scopus database, and limited to those discussing the topic on reflective approaches in medical education. Published papers that have the main search terms in the articles’ title only were tabulated. The data were then filtered using other Reflective related terms. Thematic analysis was done. Results: Two hundred and four articles were identified to have one or more search terms in the articles’ titles only. Studying the data using other reflective related terms revealed that the term “Reflective Writing” contributed the highest frequency, followed by “Reflective Journal” and “Reflective Learning”. Twenty- four studies evaluated students' reflective approaches in assessing and improving the domain of professionalism in Medical sciences. Twenty-two studies showed the researchers utilized various types of reflective approaches for evidence of students learning skills. Other studies noted the efficacy of different types of reflective learning in the domains of attitude, teamwork, empathy, learning skill, competencies, clinical skill and patient care. Pertinent to Medical imaging education area, only two studies were found; one reported the promotion of reflective learning while the other touched on the portfolio. Conclusion: This review, based on Scopus database, depicts the educational approaches that made use of the concept of reflection. They are used to facilitate the learning and assessment in various medical disciplines. There is a dearth of articles that address reflective approaches in relation to Medical imaging education. Much work is required to understand how reflective approaches can be used to effectively assess the students’ performances in various domains in Medical imaging education.
