Exhaust Gas Recirculation as a NOx Reduction Technique for Modified POME Fuelled Diesel Engine
Authors: Shivashimpi M.M. , Alur S.A. , Banapurmath N.R.
Published: March 2022

The exhaust gas recirculation (EGR) consists of reverting a certain portion of the exhaust gases into the engine cylinder. EGR dilutes the air-fuel mixture in the cylinder reducing the combustion chamber temperature and NOx with a penalty in the value of brake thermal efficiency. EGR as a NOx reduction technique for modified POME fuelled diesel engines has been investigated in the present work. The EGR rate is varied from 0% to 20% for the present study. An EGR rate of 10% has been optimized which results in the decrease in brake thermal efficiency by 3.4%, peak pressure (PP) by 5.6%, heat release rate (HRR) by 10.8% and oxides of nitrogen (NOx) by 1.2% as compared to that without EGR. An increase in emissions such as carbon monoxide by 5%, unburnt hydrocarbons by 10.5% and smoke by 12.8% are observed.

Published: March 2022

Aluminium composite plays a significant role in the mechanical structures. Low tensile strength of the aluminium alloy limits its application in mechanical structures. Graphene hydroxyl (GrOH) is a noble emerging material which is an allotropic form of carbon. It has high cohesive strength, good bonding ability with other materials. Carbon bonds processes high compatibility when it reinforced with other material. Reinforcement of GrOH with aluminium composites enhances the wear strength of composite material. This paper focused on analysis of tensile properties and percentage elongation of aluminium composites reinforced with GrOH with various weight percentage (wt. %). The characteristics of aluminium composites, particularly related to its tensile properties are very much important for its use in vehicle structures applications.

Published: March 2022

Hyperloop is a new transportation concept in which capsule travels in a lower pressure seal tube. For an hyperloop capsule, wing and spoiler mounted to investigate the effect at different deployment angles 30 60 and 90. In this paper, the wing is designed to increase the aerodynamic drag base brake force and downforce by the pressure difference on the wing. The spoiler is designed to increase the downforce by deflecting the airflow at the rare of the capsule. Prototype hyperloop capsule, wing and spoiler are modelled using CATIA V5-6R 2018 software and numerical analysis is carried out using ANSYS CFX 2021 R1 software for all aerodynamic setups. The study of wing and spoiler with different deployment angles on the hyperloop capsule can be utilized to enhance the aerodynamic drag base brake force and downforce performance of the hyperloop capsule. A detailed comparison is presented between the regular capsule, capsule with wing, capsule with spoiler and capsule with both wing and spoiler. Using a wing and spoiler with different deployment, angles on the capsule is more effective than the regular capsule.

Abdominal apoplexy: rupture of short gastric artery after retching
Authors: Ambikapathi Theiyallen , Subramaniam Sentilnathan , Hayati Firdaus
Published: March 2022

Abdominal apoplexy, or idiopathic spontaneous intraperitoneal hemorrhage (ISIH), is a rare but often fatal condition resulting from a variety of disease processes affecting abdominal vasculature. A 30-year-old woman presented with acute abdominal pain and breathlessness and was in class II hypovolemic shock. She had a history of multiple episodes of retching with non-bilious vomiting prior to that. Computed tomography (CT) reported a non-rotation of the gut, gross intraperitoneal free fluid with debris, and possible perforated appendicitis. Laparoscopy revealed a gross hemoperitoneum of 2.5 L, with bowel findings consistent with non-rotation of the gut, but technical difficulty in identifying the source of bleeding led to conversion to laparotomy. A ruptured short gastric artery was ascertained to be the source of bleeding and was successfully ligated. A retrospective review of the preoperative CT showed intraperitoneal free fluid with Hounsfield unit measurements of 48 and 52, suggestive of acute hemoperitoneum. ISIH is often a delayed diagnosis or missed diagnosis due to its low incidence. The presence of vomiting and abdominal pain with hypovolemic shock, especially in a young individual, should raise the suspicion of ISIH, which can be confirmed via early CT imaging to facilitate achieving hemostasis during surgery.

Published: March 2022

Background: Hydatidosis is a major health problem is many countries. It is a parasitic disease that can affect adults as well as children. Hydatid cyst often involves the lungs in children. Given the anatomical and physiological differences between children and adults, generalization from adult studies is inappropriate. Methods: To determine particularities of lung echinococcosis in children, we conducted a retrospective study of all cases treated for hydatid cyst of the lung at our department. Results: One hundred fifteen children (average age, 7 years 6 months; range, 3–15 years) were managed for pulmonary hydatid cyst, which corresponds to 66% of all hydatid localizations. Male predominance was noted (sex ratio=1.94). Cough (60.9%) and chest pain (59.1%) were the most common clinical features. Fever and fatigue were noted in 57 (49.5%) and 34 (29.5%) cases, respectively. Giant cysts were seen in 11 patients (10%). The cysts were mostlydiagnosed when they are intact (68.7%). Mixed hepatic and pulmonary cysts were noted in 27 cases (4.25%). Conservative muscle-sparing surgery was performed in all cases. Complications were noted in 20% of the cases. Conclusion: As hydatidosis has a different pattern in children, optimal management requires a better knowledge of its particularities in this age group.

Authors: Nyakiti George Otieno , Ooro Brian Odhiambo
Published: March 2022

Beckwith-Wiedemann Syndrome is a congenital disease that is rare and has low prevalence worldwide. It presents classically with features of macroglossia, abdominal wall defects (omphalocele), and macrosomia at birth. Other typical manifestations include facial nevus simplex, ear lobe abnormalities (creases and/or pits), transient hypoglycemia, and renal abnormalities seen on ultrasound. We report a case of a female preterm infant of twin gestation presenting at our level 4 hospital’s newborn unit with typical features of the syndrome. We aimed to create further awareness on the diagnosis in secondary health institutions and management of common features and complications of the syndrome. There is a paucity of pictorial evidence of morphology and literature related to the syndrome in an African child and this case report aims to improve that. No case has been previously reported in the Kenyan setting.
Rethinking Monotheism: Some Comparisons between the Igala Religion and Christianity
Authors: Ho Pao-Shen
Published: March 2022

The Igala religion believes in the supreme God (Ọjọ) as well as the ancestral spirits (Ibegwu). This belief system gives rise to the question of whether the Igala religion is monotheistic or polytheistic. Isaiah Negedu has recently argued that the Igala is a peculiar form of monotheism, namely inclusive monotheism. In contrast, this essay compares the Igala understanding of ancestral spirits with the Christian notions of angels and patron saints, and argues that the question of whether the Igala religion is monotheistic or not concerns how we define monotheism and is therefore merely verbal and will not promote our understanding of the Igala religion.

Authors: Schmachtenberger Harrison , Hey Mei-Li , Lumori Mikaya LD
Published: March 2022

The material presented in this paper was derived from research on sources of current literature that address global sanitation problems, especially in Uganda. Information gathered from interviews with Ugandans provided a vital component. The paper presents background information on the sanitation issues faced by Ugandan children in general and by individuals with physical disabilities in particular. It reviews the global progress being made to achieve international goals of sanitation and hygiene and compares them to the situation in Uganda. In particular, the paper sheds light on how, in the past two decades, Uganda has made meaningful strides with regard to equal rights and societal inclusion for individuals with disabilities, including access to improved sanitation facilities as well as regulations to ensure the cleanliness and hygiene of public facilities. However, these achievements do not include assistive technologies that can enable the physically disabled to use the many sanitation resources such as pit latrines in rural areas. Finally, the paper describes research that focuses on a marginalized group of disabled Ugandans who are excluded from the solution landscape.
Double uterus in young women delivered by Caesarean Section: five cases from South Sudan and Ethiopia
Authors: Gang Jok Thikuiy , Lueth Garang Dakjur , Jwodh Onwar Otien
Published: March 2022

Double uterus (uterus didelphys) is the second least common congenital anomaly of the female genital tract resulting from failure of fusion of the two Müllerian ducts during embryological development, leading to duplication of the uterus and the cervix. The condition may be associated with abnormalities of the Wolffian duct such as ipsilateral renal agenesis. Presence of a double uterus increases obstetric complications. We report five cases of young women with uterus didelphys who were delivered by Caesarean Section for obstetric indications.

Authors: Halfon Ester , Biton Yaniv
Published: March 2022

As part of efforts to improve the quality of mathematics' teaching and evaluation, we examined the focus of math teachers' considerations in evaluating students’ achievements, as well as the links between these focuses, regarding differences between students and the validity and reliability of assessment methods and examinations. Based on the categorization of issues that concern math teachers while assessing their students, a self-report quantitative-questionnaire was constructed and validated. The questionnaire included three foci of consideration for mathematics evaluation: considerations regarding evaluating learners, considerations regarding the choice of assessment methods, and assessment considerations that are unique to mathematics; positive, high, and significant were found between them. The main conclusion is that math teachers aspire to evaluate their students on the basis of a broad picture, that considers the needs of students studying mathematics as a unique discipline, the available assessment methods and their ability to adapt them to a valid and reliable assessment in mathematics, and the overall need to focus on the challenges and difficulties which are unique to assessing the discipline of mathematics. The findings also strengthen the claim that assessing math learning has unique considerations that are distinguished from assessment considerations in other disciplines.

Learning Interest and Discipline on Learning Motivation
Authors: Herpratiwi Herpratiwi , Tohir Ahmad
Published: March 2022

In the education process, almost all skills, knowledge, habits, and attitudes are developed through the learning process. Achieving good learning outcomes involves several components, such as interests, talents, good psychological factors, abilities, motivation, attitudes, maturity, discipline, and others. This study aims to determine the influence of learning interest and discipline on learning motivation. The population was university students, and the sample of the study was all students who took the basic course of curriculum development in 2019-2020, totaling 38 students. Data analysis was performed to describe the condition of each research variable learning interest, discipline, and learning motivation. Data were then analyzed by ANOVA with SPSS Program Version 16. In this study, we found that interest in learning and discipline significantly influenced learning motivation. This relation can be seen in the value of the ANOVA analysis was statistically significant (p 0.05). Interest in learning influences learning motivation, and this also applies to disciplines that have a strong influence on student motivation. Thus, student learning motivation can be increased by high effort and attention in increasing and developing student interest and discipline. The interest in learning and discipline has a positive influence on learning motivation. Learning motivation is not only influenced by interest and discipline but in this study, it is only limited to interest and discipline, which affect students' learning motivation. Other researchers can do related research talents, good psychological factors, abilities, or attitudes.

Published: March 2022

Air pollution has evolved into a global issue that necessitates immediate and accurate pollution control. The usage of the Metal Oxide Semiconductor (MOS) sensor as a monitoring system for air pollution levels is one possible answer to this challenge. The MQ-136 sensor is calibrated using standard SO2 (0, 5, 10, 20, 30, 40, 50, 60, 70) ppm as the test gas in this study. To collect the sensor output signal, a variety of equipment was created, including a gas test box, a voltage divider, and follower circuit, and a gas flow control unit operated by a microcontroller. The test gas can be pumped into the test box at a constant rate of 1.0 L.min-1 by the apparatus. To evaluate a significant difference (= 0.05), an analysis of variance was performed on the response signal generated by a series of sensors due to the concentration of the test gas. To examine the correlation between the sensor response signal and the test gas concentration treatment, as well as the sensor performance, linear regression analysis was used. The ANOVA results demonstrate no significant differences amongst the sensors, indicating that they all follow the same routine. Furthermore, ANOVA analysis reveals that the sensors respond differently at each level of SO2 concentration. According to linear regression, the relationship between gas concentration and sensor-1, sensor-2, and sensor-3 output signals is reflected by coefficients of determination of 0.94, 0.91, and 0.93, respectively.
PENANGANAN KOMPREHENSIF PADA VERNAL CONJUNGTIVITIS
Authors:   Universitas Methodist Indonesia, Surjani Lylys
Published: March 2022

Vernal keratoconjunctivitis (VKC) is an allergic eye disease with a chronic inflammatory condition, mostly bilateral, and affects upper tarsal conjunctiva. VKC is characterized by conjunctival infiltration by various types of inflammatory cells, especially eosinophils, although VKC was previously considered an IgE-mediated disease, but several other immunological pathways such as an increase of activated CD4 + T-lymphocytes, especially Th2, indicates that hypersensitivity reactions are found against unknown pathogens. The rate of eye infection with shield ulcers ranges from about 9-10% which Staphylococcus epidermidis and Streptococcus pneumonia are the most common bacteria founded. Patients with VKC often present with symptoms which are intense itching, hyperemia conjunctiva, and watery eyes, photophobia, and a sensation like a foreign object. Clinical signs of VKC include papillary reactions of the upper tarsal conjunctiva and throughout the limbus. When eyelid eversion, bulbar and tarsal conjunctival hyperemia can be observed in the presence of papillae of varying size and occasionally a gelatinous infiltrate in the limbus area (Trantas Horner's nodule) which is necessary for the diagnosis of VKC. Avoiding specific/nonspecific triggers can prevent severe manifestations of VKC. Topical lubrication with artificial tears is used for the long-term management of VKC patients, both during the active and passive phases. The main focus of VKC medical management is to relieve symptoms and prevent complications, the types of medications used include antihistamines, mast cell stabilizers, steroids, and immunosuppressive eye drops (Cyclosporin A (CsA) & Tacrolimus). Supratarsal injection of either short or medium-acting corticosteroids is recommended as a therapeutic approach in patients with VKC. Excision of the giant papilla of tarsal conjunctiva with 0.02% intraoperative mitomycin-C was recommended in cases resulting in ptosis.

In preference to the promotion of a novel reporting form, IR is regarded as an outcome of a prolonged process of global commercial integration (Vitolla et al., 2017). The application of IR is a spectacular advance towards sustainable development and information transparency (Vitolla & Raimo, 2018). This study is conducted for measuring the benefits of integrated reporting for listed firms on the Vietnamese stock market. We employ some descriptive analysis, Cronbach's Alpha and Independent T-test for evaluating and measuring the benefits of integrated reporting for listed firms. The results show that the benefits of integrated reporting for listed firms achieved an average of 3.99 in the Likert of 5 grades. There is not insignificant difference on evaluation of the benefits of integrated reporting for listed firms in terms of gender. But, the study finds differences on evaluation of the benefits of integrated reporting for listed firms in terms of work experiences. Based on findings, some recommendations are given for listed firms to set up integrated reporting.
Paraquat Poisoning – A Brief Overview
Authors:   Assistant Professor (Former) -Emergency Medicine Department Nizam’s Institute of Medical Sciences, Hyderabad ,Telangana, Gankidi Vishwa Reddy
Published: March 2022

Paraquat poisoning in the modern era has become a major medical health problem, due to its high case fatality rate. The toxicological importance of this herbicide is due to its inherent toxicity and lack of specific antidote . It is one of the commonly used agents responsible for death among the reported pesticide poisonings in south east Asian countries. The high mortality rates associated has led to the withdrawal of this herbicide from the market by the European Union in 2007, but in developing countries like India it is widely marketed due to its low cost and high efficacy . Although several studies have been done globally, there are no extensive published human trials. In Asian pacific regions where pesticides are commonly used for suicidal or homicidal ingestion, it has become a subject of concern and there is a growing need to focus on prevention due lack of specific antidote .This article endeavors to revisit the profile of paraquat (PQ) and to investigate the impacts of this chemical on human health with a future direction to create awareness about this highly toxic nonselective herbicide and to consider it as a part of national strategy to lower suicidal mortality rates.

The COVID-19 infection which is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to severe respiratory illness especially in male adolescents. This systematic review article aimed to compile and illustrate clinical features, diagnostic findings, management, and outcomes manifesting in adolescents in myocarditis associated with mRNA Covid-19. A literature search was accomplished for published eligible articles with MEDLINE and PubMed. All eligible case reports and case series were included from around the world without any language restrictions. For this review, inclusion criteria were confirmed-confirmed SARS-CoV-2 infection cases reporting a diagnosis of myocarditis in adolescents. A total of 6 articles with a total number of 107 patients were included. Patients presented with fatigue, fever, headache, malaise and chest pain. The median age of these patients was 16.23 years. Cardiac biomarkers troponin was raised in almost 78.5% of patients. Elevated C-reactive protein levels were also reported in some of the patients. Electrocardiography results demonstrated ST-segment division while echocardiography showed normal in 4.67% of the studied patients and left ventricular systolic function in 3.74%. Hydroxychloroquine, antiviral therapy, corticosteroids, nonsteroidal anti-inflammatory drugs, intravenous immunoglobin, and glucocorticoids were the most frequent used medications with no death recorded. Common available data on COVID-19 myocarditis among adolescents is limited. Further research is therefore needed to advance the understanding of COVID-19 myocarditis among adolescents.

Background: Health literacy is the ability to seek, understand, and use health knowledge, is considered crucial to successful management disease and to determinant of health status. This study aims to determine factors which influence health literacy of older adults attending outpatient clinics at a teaching hospital in a middle-income country. Methods: A convenient sample of smartphone users aged ≥55years, recruited from the hospital outpatient department,, were recruited. HL was measured with the European Health Literacy Survey Questionnaire (HLS-EU-Q47) was utilized. The cut-off value of above 33 was considered adequate for the overall general HL index (GHLI) and well as individual domain indices. Results: Of the 580 respondents, mean (SD) age 67.9 (8.0) years and 319 (55.0%) women, 240 (41.3%) had GHLI score >33. Education, occupation, hypertension, high cholesterol and eye disease were associated with lower GHLI scores. Multivariate logistic regression models revealed that <5 years of education, homemakers and hypertension were independently associated with poorer GHLI scores, while all domain indices were additionally associated with ischaemic heart disease and DPI ≤33. Conclusions: Three out of five individuals aged ≥55 years scored beneath the desired cut-off for HCI. Lower education levels, homemakers, hypertension, high cholesterol and eye disease were independently associated with index scores ≤33 in at least one domain or the overall scores Future studies target individual with lower education levels, hypertension, high cholesterol, ischaemic heart disease and eye disease for interventions which enhance HL.

Antimicrobial peptides (AMPs) are natural antibiotics, synthesized by ribosomes, with an effect on the natural immunity of animal organisms. AMPs differ in composition [sequence and type of amino acids (AAs)] and structure, which contribute to rapid lysis and have a varied spectrum of antimicrobial activity. AMPs are: peptides (Pps) with alpha-helix structure (i.e., cecropins, magainins, mellitin, etc.); cyclic Pps and ring with several cysteine residues (i.e., defensins, protegrins, etc.); Pps rich in one or another AA (i.e., proline arginine-rich PR39, histidine, glycine, etc.). Most AMPs are characterized by hydrophobic and cationic properties, adopt an amphipathic structure (alpha-helix, spiral beta or alpha-helix / spiral beta), which is essential for antimicrobial activity. AMPs have the potential for therapeutic use in medicine. One of the major concerns of life sciences research is finding new ways to enhance the body’s defense against pathogens. One way is to produce drugs based on AMPs. The AMPs are a class of small Pps that have the ability to destroy pathogens of microbial and viral origin. The mechanisms of action are known only partially and for a small number of AMPs, and the toxic action of AMPs is generally considered to be based on the induction by these molecules in the outer membrane of the pathogen of aqueous pores that facilitate nonspecific ion transfer, which ultimately leads to lysis of the target cell.
Code of ethics for electronic media in Pakistan
Authors: Ahmad Awais
Published: March 2022

“Who will watch the watchdog” This praise became popular in Pakistan when Geo, one of Pakistan's most-watched television news channels in Pakistan, has many times violated codes of ethics that were proposed by Pakistan Electronic Media Regulatory Authority (PEMRA) (Pakistan Voice, 2012, p. 2-6). Media plays an important role in our daily lives, as its basic function is to inform, educate and entertain. Today?s world media is getting more and more power because it plays a role of watchdog on politicians, governments, judiciary and our actions and can quickly inform masses and disseminate information across the globe. Therefore, freedom of media is very essential if it plays a constructive and significant role for people living in a democratic country like Pakistan. But if the press itself is not free then how can it play a constructive role or can raise voice for the rights of the citizens. Edmund Burkey (1787) stated that media is the fourth-pillar of the state. He termed it fourth-pillar because of its constructive role in our lives, the press or media can only perform its sacred duties of the fourth estate if it is free and independent in covering different aspects of life, whether it is politics, education, health, religion, war zone or any other important topics. Most importantly, it is only possible if the job is done professionally, ethically and with full responsibility.
Analysis of the Business Inequalities Stimulated by the Fourth Industrial Revolution Between Corporates and Small and Micro Enterprises in South Africa
Authors: Selelo M.E. , Khwela M.N.
Published: March 2022

Most of the authors have discussed how technology could enhance the effectiveness and efficiency of the production in various businesses. Yet, there is still a gap in literature, and little has been researched about the business inequalities which are fuelled by the Fourth Industrial Revolution (4IR) between Small and Micro Enterprises (SMEs) and corporates. The aim of this paper is to theoretically analyse the business inequalities instigated by the 4IR between corporates and SMEs. The paper argues that the 4IR is advocated by the corporates to increase their production because they are well-resourced and is a disadvantage to the SMEs due to their poor resources. The inadequate analysis of the business inequalities due to the inception of the 4IR provides a vacuum for further conceptual investigation of the phenomenon. The paper used literature-based methodology to analyze the business inequalities brought by the 4IR between corporates and SMEs. This methodology provided an extensive conceptual review of the literature regarding the subject under investigation. This paper reveals that the critical factor of production in corporates appears to be technology which increases production. In that, the 4IR is beneficial to the corporates and a disadvantage to the SMEs. Therefore, the literature indicated that there is an inevitable huge inequality between corporates and SMEs. The paper concludes that there are great business inequalities between corporates and SMEs brought by the 4IR. Thus, the paper recommends the support structures/organizations to assist the SMEs to respond to the growing technology and attempt to close the business inequalities.

The data collection technique used a questionnaire about transformational leadership, work performance, and empowerment to 196 LLDIKTI lecturers in Region IX Sulawesi Island. The data analysis used descriptive and inferential analysis with Structural Equation Model (SEM). The findings of this study reveal that (1) there was a positive and significant effect of transformational leadership on empowerment, but transformational leadership was not significant on work performance, (2) empowerment was found to have a positive and significant effect on work performance. (3) transformational leadership through empowerment can improve work performance. Moreover, empowerment is one of the most important and influential processes within the framework of the transformational leadership model in encouraging work performance among lecturers. Thus, this study extended empirical research on transformational leadership and its effect on job performance through empowerment. Besides, the limitation of this research was using the unit of analysis, which only comes from LLDIKTI lecturers in Region IX Sulawesi, all private universities without involving state universities. This study showed the urgency of efforts to create greater empowerment for LLDIKTI Region IX lecturers and leaders who can significantly contribute to work performance.
