NASA’s Time to Shine: Approaching Procurement in the ‘New Space Age’
Authors: Crawford Hannah 
Published: March 2022

With the increasing presence of commercial activity in outer space, the dynamics between public and private entities are shifting. Within these changing dynamics, the role of private actors pose novel opportunities and unprecedented challenges to space agencies. This article considers the role National Aeronautics and Space Administration (NASA) has undertaken in seeking to redefine and maximize the potential these new relationships. Paying attention to how these innovative mechanisms have enabled NASA to rediscover its direction and regenerate its mission; catapulting itself to the forefront of the New Space Age, the paper analyses whether NASA truly sets a precedent for other nations and agencies to follow-suit.

Vas, István: Video games in the Education of History– An Analysis of a University Lecture
The needs of reforming the current educational methodology is in the focus of research during the past few years both in international researchers (Prensky 2006; Gee 2012) and in Hungarian researchers (Fegyverneki 2016; Prievara 2015, 2018) as well. According to the results the sphere of the current curriculum and methodology are extended with digital practices, meanwhile one has been trying to integrate videogames in the educational system (Squire 2003; Radetich 2005; Ellard 2012; Wainwright 2014). In Hungary, there is an undergoing research of using video games in education since 2016 (Vas 2016, 2017, 2018). This article represents a research update, where according to the main concept, video games should be used in university education for the teacher training students to get acquainted with the methodological possibilities in order to use them bravely in the future. As a pilot lecture for the further research a university course was kept in the second semester of 2017/2018 with the author’s supervisor in the University of Debrecen. The article summarizes the experience of the lecture, the requirements and the syllabi of the course, and introduces the results of the three surveys, which were filled during the semester (N=82). The surveys investigated different approaches towards video games like the gaming habits of the students, the platforms they use, their opinions about the four categories based on using video games in History lessons in high schools and how the students feel the lecture successful. The course was taken by first- and second years students’, who use mainly laptops (52.4%), smart phones (48.4%) and computers for playing video games. According to the different styles of video games, they prefer mobile games (2.86); however, there are differences between males and females. As for educational purposes, they would use grand strategic video games (3.28) yet in terms of franchises, they would use the Assassin’s Creed-series (3.69), while in classes they would use them in language sessions (26%). According to the positive feedbacks of the lecture, using video games in the university for teacher training students is a motivational way of establishing a methodological open-mindedness for their future profession.
EVALUATION OF SEISMIC IMPACTS OF STRONG EARTHQUAKES IN VARIOUS PERMAFROST AND SEISMIC ZONES OF THE MONGOLIAN-SIBERIAN REGION

Published: March 2022

Based on the study of the features of seismicity within the limits of continuous permafrost and in transitional climatic zones, the influence of natural and climatic factors on the magnitude of seismic impacts is revealed. The results of studies carried out to develop a regional methodology for predicting the parameters of seismic effects of strong earthquakes in the Mongolian-Siberian region during permafrost degradation are summarized. These results are based on the data of complex geophysical measurements. They are aimed at developing methods and techniques for assessing the seismic impacts of strong earthquakes on critical engineering structures located within the permafrost zone and at developing recommendations for conducting seismic micro zoning in various seismic-climatic zones of Siberia and Mongolia, taking into account potential earthquake sources.The main goal of this study is to use the data obtained in planning and construction in seismically active permafrost areas. The developed methods and approaches are presented at the current level of requirements for the design of earthquake-resistant structures in the permafrost zone in specific areas: at the Uyanga site sum, located in Northern Mongolia, and at the Tupik site (using the example of the construction of a tailings dam), located in Russia in the Zabaykalsky Krai (Transbaikal Territory). The first section is located in the zone of insular permafrost with a probability of earthquakes of VIII-degree intensity. The second is in the area of continuous permafrost with a likelihood of VII-degree earthquakes.The proposed and implemented integrated methodological approach makes it possible to obtain at the present level of research for the natural and predicted state of soils in the foundations of designed structures a set of seismic characteristics (accelerograms, spectra, frequency characteristics) and the main parameters of seismic effects for predicted strong earthquakes (maximum accelerations, prevailing frequencies, maxima spectra and resonant frequencies). The noted set of characteristics and parameters of seismic effects meets the modern requirements of designers. It should be accounted for earthquake-resistant structures located in various seismic-climatic zones of the Mongolian-Siberian region.

Potamophilus kelabitensis sp. nov., a new riffle beetle (Coleoptera, Elmidae) discovered in the Kelabit Highlands (northern Sarawak) and Sapulut environment (southern Sabah), is described. Illustrations of the habitus and diagnostic characters of the new species are presented. Differences from the type species P. acuminatus (Fabricius, 1792) from the Palaearctic region, based on DNA barcodes and morphological characters, are discussed. Selected morphological characters of all known species of Potamophilus from Vietnam, Myanmar, and Papua New Guinea are also compared with the new species. The systematic position of the genus relative to other sympatric genera of the subfamilies Larainae LeConte, 1861 and selected Elminae Curtis, 1830 belonging to three tribes is discussed based on phylogenetic trees inferred from the mitochondrial COI and nuclear ArgK as well as 18S rRNA gene sequences.
A Panel Method for the Analysis of the Flow Around Highly Skewed Propellers
Authors: Hsin Ching-Yeh , Kerwin Justin E. , Kinnas Spyros A. 
Published: March 2022

The present work is concerned with the performance of panel methods when applied to the analysis of the flow around highly skewed propellers.
A potential-based low-order panel method, which discretizes the propeller surface with planar quadrilateral panels, has been applied to analyze the flow around a propeller with extreme geometries. The results are much less satisfactory than for conventional geometries. It is then demonstrated that hyperboloidal panels improve the performance of the method substantially. A grid oriented along constant radii generates panels with high aspect ratio and high skewness near the propeller tip, which results in inaccurate calculations of velocities. A "blade orthogonal grid" is developed to solve this problem. Improvements are obtained with this gridding scheme.
A linear relationship has been found to exist between thickness and circulation distribution for hydrofoils and propellers. A consistency test is imposed by applying this linear relationship to compare the results of the panel method and a lifting surface method. Finally, the improved propeller panel method is tested for convergence, and compared to other methods.
Energy Saving Device-A Research for Production of Rudder-Ball and Wake Equalizing Ducts
Authors: Dayuan Din , Hwaishu Yang 
Published: March 2022

During the past ten years, the world’s shipping business has been affected greatly by the increasing price of fuel. Energy-saving research has been increased in order to find ways of reducing operating costs of ships. Wake equalizing ducts. Grim wheels, rudder--balls added thrust fins. reaction fins, and other devices have been developed. Among these devices, the energy-saving gain of the Grim wheel is high. but due to its complicated design and production, its production cost is high, and until n~ the technology of astern maneuvering with Grim wheels has not been fully mastered. Difficulties still have to be overcome.
Comparatively, the energy-saving gains of the added thrust fin is offset by its ease of running into fishing nets, and therefore its use is rather limited. Rudder-balls and wake equalizing ducts are simpler in structure. Low in manufacturing costs, lightweight easy to install, and good in energy-saving effect.
Therefore, the use of rudder-ball and wake equalizing ducts is highly recommended and is widely accepted by shippers. To explore the special features of rudder-halls and wake equalizing ducts, we have carried out model tank tests for the 65.650 DWT bulk carriers built by Jiang Nan shipyard and have obtained satisfactory results. According to the tank test results. at a draught of 12.50m and designed ship speed of 14.50 knots, an 8.38% reduction of DIIP has been obtained with the simultaneous use of rudder-hall and wake equalizing ducts. When the draught of 13.l()m and a ship speed of 14.5 knots the reduction of DHP is 8.76%. At ballast condition of 32.000t. it is only 4.0%. Therefore, the simultaneous use of rudder-hall and wake equalizing ducts is a practical solution for energy saving in fully laden vessels.
Geometric morphometrics as a tool to understand biogeographical and evolutionary patterns in crane fly genus Ischnotoma Skuse (Diptera, Tipulidae)
Authors: Gouvêa Jéssica , Gil-Azevedo Leonardo H. 
Published: March 2022

Background
The geometric morphometric analysis is applied for the first time for the family Tipulidae to distinguish evolutionary and biogeographical patterns on Ischnotoma species from Neotropical and Australian regions. We included 45 recognized species of the genus, representing its three subgenera I. (Icriomastax), I. (Ischnotoma), and I. (Neotipula). This paper aims to test if the three subgenera are recoverable using this set of morphometric data.

Methods
Twenty-two landmarks were selected on the wing, mostly located on the radial and medial veins. A Regression Analysis, Principal Components Analysis (PCA), a Shape Coordinates PCA and a Canonical Variate Analysis (CVA) were used to test the variations among individuals, wing shape and groups.

Results
For all analyses, the species of Ischnotoma (Neotipula) has a strong dissociation from the remaining species and the CVA shows a complete separation of the three subgenera. This study represents the first insight for a new assessment of Ischnotoma and the first step to giving a possible new status for I. (Neotipula).

Authors: Sawhney Shraddha , Mishra Naman 
Published: March 2022

The Ilizarov ring fixation system is used to treat fracture, osteomyelitis, and bone lengthening. Wires and pins are used in order to fix the Ilizarov frame to the affected bone. In patients with Ilizarov ring fixators, pin site infections (PSI) are the most prevalent problem seen by orthopaedic surgeons. Pin sites are prone to infection because the skin barrier is lost or broken, disrupting the body's natural defense against bacterial infection.
This was a cross sectional study and 30 patients divided in 2 equal groups, each contained 15 patients were taken under study. The present study included patients treated with Ilizarov external fixators post-injury and followed-up at Orthopedic OPD by history, clinical examination and radiological evidence. 235 pin sites were examined -in all the 30 patients. Demographic information, socioeconomic status, and health status were asked and recorded in the patient identification forms. It was found that, Only 19 of the 125 pins cleaned with chlorhexidine showed evidence of infection, but 32 of the 110 pins cleaned with povidone iodine solution showed infection (p value 0.05This was found to be statistically significant. In the participating groups, the location of infection was not important. The povidone iodine group had the first-degree infections, followed by second- and third-degree infections. According to the Checketts otterburn classification scale, the chlorhexidine group did not report any third-degree infections.
Maximizing Drug Effect & Reducing Pain by Placebo Drug Therapy by Diminishing and Ending Use of Painkillers/ Anaesthesia in Chronic Painful Disorders
Authors: Hedau Vedant , Patond Swapnil 
Published: March 2022

The placebo effect has shown prominent results with scientific evidence. It is the methodology of giving placebos that raises questions. There is limited investigation/research on the placebo pain-relieving effects. As the ethical concerns have contended. Many medical service providers use placebo habitually and patients are accepting these interventions. The positive patient-clinician outlook is very essential to develop a clinically meaningful placebo effect in chronic pain patients. For clinical use of placebo, it is important to understand that placebo-based clinical trials yield ethical possibilities and boundaries. Since the placebo effect contributes to active responses, it is possible to enhance the positive placebo effect. Placebo is psycho-neurobiological responses capable of modulating pain and producing variable changes of the different neurobiological bodies at emotive and analytic levels. This development can be achieved by different contextual factors (CFs) presented in the therapeutic encounter between patient and healthcare provider, such as healing rituals and signs. The CFs directly impact the quality of the therapeutic outcome. When we say chronic pain, we know the patient is suffering from some condition for a long period of time. In this scenario, there are high chances of a patient taking some pain management medication. Most chronic pain conditions such as arthritis, osteoarthritis, IBS, fibromyalgia, etc. cannot be cured. Pain with time increases as the patient gains tolerance to the medication therefore the doses of the medication are increased due to no effectivity of the drug is changed. This continues lifelong, due to these heavy pain medications given with the pain causative condition medication causes various negative effects on the body. In Clinical psychology placebo, drug therapy can be very helpful in depression, anxiety disorders, mood disorders, psychotic disorders, etc. Every year, we learn new data about the clinical application of the placebo effect.
Malnutrition in Congenital Heart Disease
Authors: Musale Aditya , Gomase Shantanu 
Published: March 2022

Congenital heart disease accounts for nearly twenty-eight percent of all the major congenital malformations, posing a significant global health problem. Prevalence of both cyanotic and acyanotic varies from 0.7 to 5.3/1000 patients in community-based study while hospital-based study statistics range between 3.9 and 26.4/1000 live births. The increase in birth rate and the requirement of surgical and non-surgical intervention makes it a high and challenging need task for emerging nations like India, where the framework isn't created at the root level. In this population a high prevalence of malnutrition is seen especially in infants. In the era of high survival rates, nutrition provides opportunity for development, growth optimization and a better standard of living. The morbidity & mortality associated malnutrition in infant with congenital heart disease can be reduced by early diagnosis / optimum treatment. Approximately half of the pediatric age population suffering from Congenital Heart Disease (CHD) are found to be malnourished where the most of the affected factor is found to be weight worse than height. The various contributory factors for malnutrition in CHD patients are cyanosis, heart defects, heart failure, pulmonary hypertension, anemia, and delayed corrective surgery. Early and Timely diagnosis is crucial as most congenital heart disorders can be corrected if apt intervention is provided, leading to better prognosis. Decreased caloric requirement , reduction in prevalence of respiratory tract infection, and better absorption will lead to early normalization of their malnourishment. The major studies done in the recent past have focused on the mechanism of failure of growth in patients suffering from congenital heart malformation or on the modalities for improvement of growth of children with congenital heart disease. The severity and frequency of malnutrition associated with congenital heart diseases has not been focused on in the past decades.

Published: March 2022

Background: The global pandemic of the coronavirus disease 2019 (COVID-19) has yielded a variety of stressors (psychosocial) for the population, particularly women. The elevated stress may not only affect the wellbeing and health (physical and mental) of women, but also the reproductive status and menstrual cyclicity.
Objective: To determine the plausibility and mechanism via which stress (emanating from the COVID-19 pandemic) has impacted women's menstrual cyclicity.
Methodology: This descriptive, cross-sectional study was conducted from Sept 2020 to August 2021 upon a randomly selected sample of 1450 Pakistani women (aged 18 to 40 years). The data was collected using an online questionnaire containing enquiries pertaining to basic biodata, sociodemographic details, lifestyle patterns, medical & reproductive history, and stress score measured via the COVID-19 Stress Scales (CSS). The data obtained, was analyzed using SPSS v. 21.0.
Results: Among the females, 741 reported regular menstrual cycles, while the remaining 709 reported a disturbed menstrual cyclicity. The commonest changes included early or late start of the cycle (227), more aggravated menstrual symptoms (e.g., cramping, discharge and low back pain) (205), and menorrhagia (277). Individuals with aggravated symptoms of ill-timed cycles scored higher (cumulatively as average scores) on the CSS compared to their counterparts (p < 0.05).
Conclusion: After careful consideration of the results, it can be concluded that a significant association exists between the stress (emanating from the COVID-19 pandemic) and menstrual irregularity (p < 0.05). Stress relief may help alleviate menstrual irregularities in the current scenario.
