Authors: Moiz Uddin Ahmed  , Muhammad Ikram -ul-Haq
Published: February 2024

The use of technology has become inevitable in every field of life including the education. The distance learning is also shaping towards smart online learning, therefore, posing many challenges of content development and delivery through the smart devices. One of the challenges is the development of adaptive assessment for anytime and anywhere mobile learning. The COVID-19 has posed an extra requirement of reshaping pedagogies on hand-held devices. The current study takes up these challenges and proposes a model of adaptive assessment for mobile learning. The Item Response Theory has been employed to estimate the learning ability and tailor a personalized learning trajectory. The model was implemented on a bachelor level course offered by an open university of Pakistan. A mobile application was developed and one hundred and eighteen students were enrolled. They used the app in addition to other traditional activities for a duration of one semester. The result of final examination of adaptive batch was compared with the previous same course offered through the traditional distant learning mode. The result showed sizeable improvement in the knowledge level of the distant learners. This research opens up an avenue of anywhere and anytime learning through the use of smart devices. It can help policymakers, educationists and technologists to align their online learning practices during the current pandemic.

Is it useful, acceptable, or controllable? Hong Kong primary school teachers’ online assessment practices in changing time
Authors: Zhan Ying , So Winnie Wing Mui , Sun Daner , Yan Zi
Published: February 2024

Few studies have explored primary school teachers’ classroom-based online assessment practices and underlying reasons. To fill this research gap, this study interviewed 48 Hong Kong primary school teachers to understand their online assessment practices and influencing factors when they were obliged to use it in their daily instruction under the influence of the COVID-19 pandemic. The findings revealed that the participants tended to use online tests/exercises for formative purposes instead of summative purposes. In addition, they tried online alternative assessment tasks, such as video or audio recordings, peer assessment and projects, and gave online feedback to students but less frequently than online tests/exercises. The school examination culture and the participants’ perceived limited control over online test fairness may have restricted their summative use of online tests/exercises. Meanwhile, the participants’ perceived positive usage norms, along with their favourable attitudes towards and confidence in using online tests/exercises probably enhanced their formative use of them. In addition, the participants’ perceived neutral usage norms and limited external control of online alternative assessment tasks and feedback seemed to impede their use of them in classrooms.

The study of global and vertical solar irradiance components under different sky conditions is very important for building design applications. This research has been carried out by analyzing the components of solar radiation based on global horizontal irradiance (GHI) data, and global vertical irradiance for east, west, north, and south oriented. Observational data was acquired for one year starting from July 2022 to June 2023 in Jembrana-Bali of Indonesia. The solar radiation component has been analyzed based on sub-diurnal (daytime) and annual patterns. The clearness index (Kt) was calculated based on the ratio of extra-terrestrial solar radiation to global solar radiation measured at the surface. Sun-path analysis was carried out by considering the relationship of the zenith angle, azimuth angle, and the intensity of each solar radiation component to changes in time. The results show that in all-sky conditions, the average monthly maximum global horizontal irradiance occurs in January at 432.4 W/m², while the minimum monthly average global horizontal irradiance occurs in July at 327.9 W/m². The clearness index statistic shows that the hourly average ranges from 0.12 to 0.68 with an average of 0.47. Based on sun-path analysis, east, north, and west orientations receive more solar radiation in the Jembrana-Bali area. The findings from the study provide important information for architects, engineers, and policymakers that can be used for sustainable building design and building energy planning.

Published: February 2024

The Greek term for "helminthes" means "worm." Human-infecting parasites fall into one of two categories: keepsakes or heirlooms. Heirlooms are parasites that have been passed down from African ancestors, while souvenirs are parasites that humans have picked up from animals through migration, evolution, and agricultural activities. These helminthic infections are the most prevalent human infectious agents in poor nations. The helminthic parasite affects around 2 billion people worldwide, or more than 25% of the total population. It is a big problem in developing nations, particularly for young people. Therefore, the goal of the current study was to extract the plant's active ingredients and test the crude extract's anti-helminthic properties. In this study, we worked on the ceasalpeniapulcherima plant with a focus on natural remedies for the treatment of helmintiasis. The chief scientist of Sri Konda Laxman Telangana State Horticulture University, Floriculture Research Station, Rajndranagar, authenticated the true nature of the plant. Water and ethanol were utilized in the extraction procedure. To find out what chemicals are in the alcoholic extract, a screening test is performed on it. The flavonoid test on the extract came out positive. Using Albendazole as the prescribed medication, the anthelmintic action was carried out on Indian earthworms. In Indian earth worms, we found that alcoholic extract exhibits good antihelmintic action. By Insilco studies we found the interaction of flavanoids with antihelmentic proteins. Key Word: Helminthes, ceasalpeniapulcherima, flavonoids, extractioin, in silico study.

Modeling of a Bicycle Cargo Trailer with Magic Formula Tire Model for Vehicle Dynamics Simulation
Authors: Miller Marius , Pfeil Markus , Kennel Ralph , Murri Raphael
Published: February 2024

In modern and sustainable concepts for supply chains, cargo bicycles, and cargo trailers can be a target-oriented solution in urban
areas. However, drivers should be aware of the dynamics of these systems since, in the case of a loaded trailer, the trailer mass
significantly exceeds the mass of the towing vehicle. However, the electrification of cargo trailers opens up the possibility of
equipping these systems with an intelligent control system. This type of control system can be based on a model or tested using a
model of the system. For this reason, the present research presents a single-track model of a bicycle-trailer system that considers
longitudinal dynamics as well. In addition, a detailed tire model of a typical tire for cargo bikes is integrated. With the help of a
prototype trailer, which forms the basis for the model’s parameters, measurement data is collected and compared with the simulation
results. Within the scope of the comparison, speed, acceleration in longitudinal and lateral direction, hitch force, yaw rate, and
the angle between the towing vehicle and trailer are compared in a longitudinal and lateral dynamic case. The presented model
shows a good agreement with the reality in the longitudinal dynamic investigation regarding the tested scenarios. In terms of lateral
dynamics, the model can reproduce a significant part of the measured data but exhibits minor differences related to environmental
conditions, limited degrees of freedom, measurement errors, and the implementation of a needed driver model in this setup, which
represents the human component. In the future, the model can be used to investigate the driving characteristics of bicycle-trailer
systems. Furthermore, adding a model of the trailer powertrain and its control to the simulation can enable simulation-based design
and testing of the required vehicle dynamics controller before implementation on a prototype.
On the Development of a Path Tracking Controller by combining Optimal Preview Control and Pursuit Control Methods
Authors: Gabriel David , Görges Daniel , Baumgärtner Daniel
Published: February 2024

Path tracking controllers are an important part when developing self-driving vehicles.
When designing such a controller for a single-track vehicle, a major challenge is that the vehicle not only has to follow a predefined path but has to be stabilized at the same time.
Especially if the vehicle has slow steering dynamics (e.g.
τ > 1.5s) and the path contains tight corners which should not be cut (e.g. directional change of more than 90° in less than 2s), the design of a suitable path tracking controller can be difficult.
In this work an optimal preview controller that stabilizes a bicycle and that can track a given yaw rate trajectory is combined with a quintic polynomial pursuit controller.
With this approach, we can achieve good tracking performance for the predefined paths, which can be seen in the simulation and experimental results.

PRIMARY OVARIAN INSUFFICIENCY, A CHALLENGING DIAGNOSIS. A CASE SERIES
Authors: Omar Sahil , VAYA MITAL , OMANWA KIREKI
Published: February 2024

INTRODUCTION

Primary ovarian insufficiency is rare, affecting 1-2% of those under 40 with only 0.1% of cases below 30 years. Etiology is mainly idiopathic, however chromosomal defects, autoimmune processes, and iatrogenic causes are associated. Symptoms are those of menopause but of intermittent durations and severities; and management targets the symptoms and complication prevention.

CASE PRESENTATION

We present two 18-year-old patients of African and Indian descent with an eight and five-month history of amenorrhea respectively with otherwise unremarkable history and physical exams. Investigation showed elevated FSH levels of 45.07 and 88.73 mIU/ml done four weeks apart in the first patient and 68.69 in the second patient. All other parameters were normal.

DISCUSSION

Aetiology is mainly idiopathic. 10-12% of diagnosed patients have chromosomal abnormalities such as Turner’s syndrome, fragile X syndrome, and genetic permutations of FMR 1 gene. Autoimmune causes are mainly autoimmune adrenal diseases. Autoimmune thyroiditis, Dermatomyosistis and Diabetes Mellitus type 1 also show association. Mumps Oophritis is the main infectious cause. Laparoscopic surgical procedures that involve the ovaries or affect their blood supply, pelvic radiotherapy, and chemotherapy all comprise the iatrogenic causes. Lifestyle and environmental factors such as smoking and heavy metals exposure also contribute.

Diagnosis is by serum FSH levels of above 25 IU/l in two separate readings four weeks apart with a four-month history of amenorrhea occurring before 40 Years. Both patients were under 30 and met the criteria.

Management involves hormone replacement therapy for symptoms, prevention and treatment of osteoporosis, oocyte donation for infertility, and counseling for both the psychological impact of the disease and the numerous complications living with the disease.

CONCLUSION

Multidisciplinary  care is necessary for management of this rare and challenging illness
UPTAKE AND OUTCOMES OF MILD OVARIAN STIMULATION FOR IN-VITRO FERTILIZATION IN AFRICA: A SYSTEMATIC REVIEW
Authors: Koigi Paul , Tripathi Akanksha
Published: February 2024

Introduction: Assisted Reproductive Technology (ART) is beyond the economic reach of most of those inflicted by infertility in Africa. Uptake of low-cost in-vitro fertilization (LCIVF) may improve financial access of patients to advanced fertility care.

Methodology: Systematic review of open-access full articles published in English from January 2000 to May 2023. Articles were sourced via PubMed, Medline, Embase and Google Scholar databases on June 1st 2023. Search keywords used were “Mild stimulation” OR “Low-cost IVF” AND “Africa”.

Ethics: This project was subjected to Ethics review by the University of South Wales Ethics review Committee.

Results: 5 publications included out of 647 results. These were historical reports in contextualized narrative reviews with no statistics provided. Because of this, only qualitative synthesis was undertaken, and meta-analysis was not possible due to lack of statistics for comparison. Published results indicated significant financial restriction of access and no objective demonstration of actual uptake and outcomes of mild ovarian stimulation in Africa.

Discussion: There was no actual open-access published evidence regarding uptake of mild stimulation for low-cost IVF in Africa. If there is such material, it is not available to those that would actually need the information to inform providers’ practice or patient choices. This is the case despite growing evidence of increasing utility of LCIVF outside Africa. Uptake of LCIVF may potentially ameliorate financial restrictions of access to ART in Africa.
Progestins for pituitary suppression during ovarian stimulation in artificial reproductive technology
Authors: Gichuhi Wanyoike
Published: February 2024

Background: Progestins can suppress endogenous luteinizing hormone secretion from the pituitary gland. Progestins can be used orally and are less expensive than gonadotrophin-releasing hormone (GnRH) analogs. However, early endometrial exposure to progestin precludes fresh embryo transfer (ET), but the emergence of vitrification for oocyte cryopreservation cycles allows more opportunities for using progestins for pituitary suppression.

Objective: To assess the mechanism of pituitary suppression by progestins, the effectiveness of progestins compared with GnRH analogs, the effect of progestins on oocyte and embryo developmental potential and euploidy status, and the cost-effectiveness of progestin-primed stimulation. 

Methods: A literature search using the keywords “multiple waves of antral ovarian follicular development,  In Vitro Fertilization, Ovarian stimulation ” was performed in the PubMed database.

Results: The duration of stimulation, gonadotrophin consumption, and oocyte yield were similar in progestins and GnRH analogs. However, progestins were associated with significantly lower gonadotrophin consumption than their analogs. Overall, live birth and clinical pregnancy rates per ET were similar to those of progestins and GnRH analogs. Studies comparing medroxyprogesterone acetate, dydrogesterone, and micronized progesterone suggest similar ovarian responses and pregnancy outcomes. The euploidy status of embryos and obstetric and neonatal outcomes from progestin-primed cycles are similar to those of embryos from conventional stimulation cycles. Despite the lower cost of progestins than GnRH analogs, the mandatory cryopreservation of all embryos followed by a deferred transfer may increase the cost per live birth with progestins compared with an artificial reproductive technology cycle culminating in a fresh ET.

Conclusion: Progestins present an effective option for women who do not contemplate a fresh ET, e.g., fertility preservation, anticipated hyper responders, preimplantation genetic testing, oocyte donors, and double stimulation cycles.

Published: February 2024

Gazofilacio regio, simple remedo del título de la obra de Gaspar de Escalona Agüero, Gazophilacium regium perubicum (1647), en su extrañeza actual, es una invitación al lector para que se desprenda de una posible mirada anacrónica sobre nuestro objeto de estudio, el gobierno de la Real Hacienda de Nueva España, en la medida en que su comprensión deriva de un objeto vivo en la cultura y el orden político-jurídico de la época moderna, la jurisdicción (iurisdictio), entendida tanto en su faceta gubernativa como judicial. Entre esos dos polos se desarrolla el libro que el lector tiene ante sí.Para acometer este análisis, nos hemos enfocado, prima facie, en establecer quiénes estaban investidos por la corona, fuente última de legitimidad del poder público, para dirigir el Real Haber. Con estos supuestos, nuestro estudio arranca con los primeros oficiales reales establecidos en Nueva España por la Monarquía hispánica en la década de 1520, a la par que se producía el proceso de conquista y colonización, y cuyo cometido fundamental era la protección y promoción de los intereses de la Real Hacienda. Respecto al cierre del trabajo, en 1810, su motivación se encuentra en el cambio de las bases políticas que daban sentido a la existencia de la propia Real Hacienda y, por ende, de su gobierno. Conceptos como nación, Constitución política y ciudadanía marcaban tantas rupturas como las que mediaban entre una Real Hacienda y una Hacienda pública o nacional, y, de ahí, el establecimiento de una cesura que abre un nuevo periodo.

This study is to investigate the segmental involvement of lung in COVID-19 individuals using high resolution computed tomography (HRCT) and to correlate with serum inflammatory markers. Retrospective study done in 100 COVID 19 RTPCR positive patients with radiological images were collected and analyzed for lobar involvement, bronchopulmonary segments in 3D and CT Scores and it was compared with serum inflammatory markers (SIM). Variables like gender, involvement of segments and co-morbid conditions were summarized as frequency and percentage. Sub group analysis was done using independent t test, Chi-Square. Findings revealed that males were commonly affected than females with the mean age 57.47 ± 13.0. Lower lobes and posterior basal segment of both the lungs were affected with preponderance on the left side. Additionally, SIM were up regulated in the COVID-19 individuals. Serum IL-6, D-dimer and Ferritin showed upsurge in right lung and CRP and LDH elevated in left lung in the COVID-19 and it was statistically correlated with CT severity score. Chest HRCT and biochemical parameters individually and in combination help in identifying the COVID 19 severity among individuals for preventing or reducing the mortality rate in adults.
Clinical and bacteriological profile of community acquired pneumonia in hospitalized children
Authors:   Chettinad Hospital and Research Institute, Chettinad Academy of Research and Education, Kelambakkam-603103, Tamilnadu, India, Krishnan Madhan Krishnan
Published: February 2024

Community-acquired pneumonia (CAP) is the leading cause of mortality and morbidity with important clinical impact across the World. India accounts for 23 per cent of global pneumonia burden with case fatality rates between 14 and 30 per cent. Pneumonia is basically classified into typical and atypical pneumonia. Emerging evidence indicates that dual typical and atypical bacterial infections function synergistically in many cases and together likely enhance the severity of CAP. However, the optimal management of CAP in children is still not well defined and the diagnosis is challenging when based solely on clinical observations since the common symptoms of CAP, especially at an early stage, are similar to those of ordinary respiratory tract infections. So RT-PCR is a rapid and precise molecular technique is used for rapid detection of bacteria causing community acquired pneumonia. A total of 268 samples were tested for the respective bacterial pathogens, among the tested the most common pathogen was Haemophilus influenzae (18.3%, 49/268) followed by S. pneumoniae (14.6%,39/268), M. catarhallis (9.3%,25/268),M. pneumoniae (9%, 24/268), B. parapertusis (3.4%,9/268), B. pertusis (1.5%, 4/268), C. pneumoniae (1.5%, 4/268), C. burnetti (1.1%, 3/268)and L. pneumophila (0.74%, 2/268). H. influenza and S. pneumoniae were the most commonly detected organisms among the community acquired pneumonia patients.
Initial Reconnaissance of the 2011 Wildland-Urban Interfaces Fires in Amarillo, Texas
Authors: Maranghides A
Published: February 2024

The National Institute of Standards and Technology (NIST) is working to reduce the risk of fire spread in Wildland-Urban Interface (WUI) communities. An objective of this work is to develop first generation tools for improved risk assessment and risk mitigation in WUI communities at risk from wildfires. These tools will be developed and tested through a coordinated effort that includes laboratory and field measurements, physics-based fire behavior models, and economic cost analysis models. NIST and Texas Forest Service (TFS) worked together in October 2010 to train TFS personnel in the NIST-developed WUI data collection methodology. While the fires that started on February 27, 2011 were still burning around Amarillo, NIST and TFS decided to deploy the joint Team and document the WUI fire event loses and fire behavior. The Tanglewood WUI fire in the outskirts of Amarillo was responsible for the destruction of approximately 101 structures including 35 residences. Field measurements included structure particulars, specifically building construction materials, proximity and type of combustibles to the structure, and damage to wildland and residential vegetation. Documentation included over 29 000 photographs. The data collection and analysis will be documented in two phases, an initial reconnaissance/overview report and a technical report. This summary report will address the particulars of the joint NIST/TFS deployment and the data collection methodology used. Additionally, this report provides a summary of the primary structures lost. A second more detailed technical report will provide the event timeline reconstruction and general fire behavior observations as well as investigate the impacts of structure attributes, landscaping characteristics, topographical features and wildland fire exposure on structure survivability

O modelo atual de produção de proteína e outros nutrientes, por meio da criação de animais, não suprirá as necessidades da população mundial até 2050. Assim, o presente trabalho teve como objetivos analisar a composição centesimal e avaliar a qualidade microbiológica dos insetos Tenebrio molitor, Nauphoeta cinerea e Gryllus assimilis visando seu uso na alimentação humana. Foram realizados abate dos insetos, desidratação e trituração em farinha integral. Efetuaram-se análises químicas nas farinhas de insetos desidratados, sendo: determinação do teor umidade, proteínas, lipídios, açúcares redutores e totais, cinzas (minerais) e valor energético total. Feitas análises microbiológicas de avaliação de coliformes totais e termotolerantes. Os resultados foram analisados estatisticamente pela análise de variância e as médias comparadas pelo teste de Tukey (p<0,05). Os resultados obtidos mostraram teor de umidade abaixo de 15g 100g-1 para todas as amostras de farinhas, que garante sua conservação e utilização no enriquecimento de farinhas para panificação. Apresentaram também alta concentração de proteínas, que variou de 39,81 a 52,06g 100g-1. Resultados do quantitativo de lipídios foi de 6,78 a 32,10g 100g-1. O teor de cinzas/minerais presentes foi significativo para alimentação humana, com baixo índice de açúcares. O valor energético total variou de 242,06 a 457,66 kcal 100g-1. As análises microbiológicas indicaram qualidade alimentar para coliformes totais, que variou de 0,36 a 2,8NMP g-1, e coliformes termotolerantes, cujos resultados se mantiveram para todos os insetos abaixo de 0,3 NMP g-1. Os resultados apontam que os insetos podem ser uma alternativa como fonte nutricional, porém, para que sejam inseridos na alimentação humana ainda há muitos aspectos a serem analisados pelos pesquisadores da área.

In the present study local information, morphology, medicinally uses, collection, stomata studies and phytochemical screening analysis of cirsium arvense has been done. C.arvense is an herbaceous wild plants belong to family asteraceae. The local information about this plant were collected from the local people of that area (Mardan). In the March to April it emerges with flower and stem from the soil. The ideal conditions for growth are high moisture content, high humidity and a temperature of around about 25 C0. This plants are used as antifungal, antiamoebic, antifeedant, antiviral, antibacterial, antimalarial, allergies, sores, anemia, fever, skin diseases and as tonic blood purifier,vermifuge,aborative and insecticide etc. The phytochemical screening analysis of tannins, flavonoids, alkaloids, steroids, phenols has been analyzed which show the presence or absence of these chemical compounds. The carbohydrate in leaf extract, the methanolic extract have carbohydrate present while in the distilled water extract and ethanolic extract was in not present. The carbohydrate in root extract, the methanolic extract shows presence and ethanolic extract shows more presence while the distilled water extract shows absence. The alkaloid in leaf extract, in the ethanolic extract is not present while methanolic extract is present and in distilled water in more amount present. The Alkaloid in root extract, the methanolic extract shows most presence and ethanolic extract shows presence while the distilled water extract shows more presence. The saponins in leaf extract, in the methanolic and ethanolic extract shows presence while in the distilled water have most presence.
Protective power: The nabau or water dragon among the Iban of Sarawak
Authors: Janowski Monica
Published: February 2024

This article discusses the origin, nature and significance of the nabau, which I gloss in English as ‘water dragon’. I show how there are clear indications that the nabau is regarded by the Iban as protective. The nabau has been woven into pua cloths, skirts and strips of cloth called labong Bungai Nuing. The nabau on labong Bungai Nuing are regarded as manifestations of a culture hero from the parallel semi-spirit world of Panggau Libau, Bungai Nuing, and they are used as protective amulets. This is the clearest demonstration of the protective nature of the nabau. I suggest that the significance of the nabau should be understood in the context of its association with water and with beliefs about the flow of cosmic power and fertility through water. The use of the figure of Bungai Nuing hints, I suggest, at the nature of beliefs about the flow of cosmic power, kuasa, and the ways in which humans engage with this.

"Second to none in the East”: Reassessing the birth of the Sarawak Museum
Authors: R. Morris Jennifer
Published: February 2024

The foundation and early history of the Sarawak Museum have long been the subject of a number of legends and misconceptions, particularly in relation to the role of naturalist Alfred Russel Wallace. This paper draws on in-depth archival research into the history of science and collecting in the Brooke State to reassess the origins of the Museum, in the political, economic and social context of late-nineteenth-century Southeast Asia. Through analysis of the colonial contexts which shaped the worldviews of both James and Charles Brooke, their attitudes to science and their political motivations, I conclude that the Museum was founded at a significant juncture in the development of Charles Brooke’s political authority in Sarawak. At the point of its conception, the Museum was intended to function as a political tool, representing the Rajah’s ambitions for Sarawak as a contender on a regional and global stage. Although not directly influenced by Wallace, it was also a product of the thriving atmosphere of scientific endeavour that was actively cultivated by the Brooke government, and which would – partly through the work of the Museum – become an important legacy of their rule.
