Published: June 2021

Coronavirus disease or more popularly called COVID-19 is known to be caused by a novel coronavirus 2. The COVID-19 has been identified to be originated from Wuhan, Hubei, China. This pandemic started in December 2019, and since then it has spread across the world within a short period. The health and family welfare ministry of the Government of India reported 227,546 active, 9,997,272 discharged cases, and 150,114 deaths due to COVID-19 as of 06 January 2021. Indian Council of Medical Research (ICMR) reports that the cumulative testing status of SARS-CoV-2 (COVID-19) was 931,408 up to November 03, 2020. Currently, no specific anti-viral drug for COVID-19 management is recommended in the current scenario. Vulnerable populations such as pregnant women affected by COVID-19 infection need to be recognized and followed up for effective handling concerning morbidity and mortality. At present, very few case reports on COVID-19 infected pregnant women have been published in India and there is no proven exclusive treatment protocol. This article summarizes a review of signs and symptoms, etiopathogenesis, risk factors, diagnosis, and possible management of COVID-19 infection in pregnant women. This overview may be useful for health care providers for practical approach and limitation of drugs used in the current management and considers the choice of drugs with their special attention given to adverse effects to improvise maternal health, pregnancy, and birth outcomes.

Background: Viral infections cause alteration in the total number of lymphocytes and their subset distribution. We aimed to study peripheral blood lymphocyte subsets in COVID-19 patients and to correlate these subsets with clinical and laboratory data, which may help in clarifying the pathogenesis to develop novel diagnostic and prognostic biomarkers for COVID-19.Methods: Twenty-six reverse-transcription polymerase chain reaction (RT-PCR) confirmed COVID-19 patients were subjected to medical history-taking and a thorough clinical examination. Laboratory tests included complete blood count, D dimer, ferritin, and C-reactive protein (CRP). Chest CT was used to diagnose COVID-19 pneumonia. Lymphocyte subsets were compared with those in 20 healthy controls using flow cytometry.Results: Leucopenia, relative neutrophilia, lymphopenia, eosinopenia together with marked elevation in neutrophil/lymphocyte ratio were observed in our COVID-19 patients. A marked reduction was observed in T cells, including both CD4 and CD8 cells, natural killer (NK), and natural killer T cells (NKT). Double-positive T (DPT) cells, double-negative T (DNT) cells, and B cells were elevated in the patients relative to the other lymphocyte subsets.Conclusion: Immune-inflammatory parameters are of utmost importance in understanding the pathogenesis and in the provisional diagnosis of COVID-19. Yet, due care must be taken during their interpretation because of the vast discrepancies observed between studies even in the same locality. Further studies are needed to clarify the role of B cells, DPT, and DNT cells in the pathogenesis and control of COVID-19.
Unsettled Issues Concerning the Use of Green Ammonia Fuel in Ground Vehicles
Authors: Kolodziejczyk Bart
Published: June 2021

While hydrogen is emerging as a clean alternative automotive fuel and energy storage medium, there are still numerous challenges to implementation, such as the economy of hydrogen production and deployment, expensive storage materials, energy intensive compression or liquefaction processes, and limited trial applications. Synthetic ammonia production, on the other hand, has been available on an industrial scale for nearly a century. Ammonia is one of the most-traded commodities globally and the second most-produced synthetic chemical after sulfuric acid. As an energy carrier, it enables effective hydrogen storage in chemical form by binding hydrogen atoms to atmospheric nitrogen. While ammonia as a fuel is still in its infancy, its unique properties render it as a potentially viable candidate for decarbonizing the automotive industry. Yet, lack of regulation and standards for automotive applications, technology readiness, and reliance on natural gas for both hydrogen feedstocks to generate the ammonia and facilitate hydrogen and nitrogen conversion into liquid ammonia add extra uncertainty to use scenarios. Unsettled Issues Concerning the Use of Green Ammonia Fuel in Ground Vehicles brings together collected knowledge on current and future prospects for the application of ammonia in ground vehicles, including the technological and regulatory challenges for this new type of clean fuel.

Published: June 2021

Background: Ghana’s maternal mortality ratio continues to decline, but is not expected to meet the Millennium Development Goal (MDG) 5 target. The Ghana Health Service and Ministry of Health have displayed a high commitment to the improvement of maternal health in the country. One of the most recent partnerships directed at this is with the Korea International Cooperation Agency.Methods: This study was conducted among women between ages 15 and 49 resident in Keta Municipal, Ketu North and Ketu South districts in the Volta Region of Ghana who were pregnant or who had children aged less than five. Ethical approval was obtained from the Ghana Health Service Ethical Review Committee. Data were collected using questionnaires, entered into Stata version 12 and analyzed using frequency distribution and assessment of means. Comparisons among districts were conducted using chi square test and one way analysis of variance (ANOVA).Results: The study covered 630 women whose mean age was 28.4 years. Almost all participants (99.1%) from Ketu North knew where to obtain family planning services. Use of modern contraception was highest in Ketu North with 31% of respondents using a modern method. Delivery in a health facility was highest in Keta Municipal (62.3%) with overall institutional delivery being 57.6%. Delivery by a skilled birth attendant (SBA) was also highest in Keta Municipal.Conclusion: Indicators used to assess maternal health services show a coverage of over 50% but we need to improve institutional delivery, use of modern contraception and education about danger signs in pregnancy. Funding: This work was supported by the National Research Foundation of Korea Grant funded by the Korean Government (NRF-2013S1A5B8A01055336) and the Korea International Cooperation Agency(2013).Keywords: Maternal Health, Ghana, Volta Region, Family Planning, Skilled Birth Attendant
Provable Security of SP Networks with Partial Non-Linear Layers

Published: June 2021

Motivated by the recent trend towards low multiplicative complexity blockciphers (e.g., Zorro, CHES 2013; LowMC, EUROCRYPT 2015; HADES, EUROCRYPT 2020; MALICIOUS, CRYPTO 2020), we study their underlying structure partial SPNs, i.e., Substitution-Permutation Networks (SPNs) with parts of the substitution layer replaced by an identity mapping, and put forward the first provable security analysis for such partial SPNs built upon dedicated linear layers. For different instances of partial SPNs using MDS linear layers, we establish strong pseudorandom security as well as practical provable security against impossible differential attacks. By extending the well-established MDS code-based idea, we also propose the first principled design of linear layers that ensures optimal differential propagation. Our results formally confirm the conjecture that partial SPNs achieve the same security as normal SPNs while consuming less non-linearity, in a well-established framework.

Authors: K Sri Sandhya
Published: June 2021

A novel Corona virus discovered during a pneumonia
outbreak in Wuhan city, China has raised a global public health
concern. This virus spread across the world affecting various
countries and was declared a pandemic by World Health
Organization(WHO). The outbreak started in December 2019
and by first week of April 2020, 212 countries were affected
with more than 1million confirmed cases with a death roll of
79,235 worldwide. This disease was named as COVID-19 and
the causative agent was named as Severe Acute Respiratory
Syndrome Corona Virus -2 (SARS-CoV-2) due to its genetic
similarity with SARS virus. SARS-CoV-2 is transmitted by
respiratory droplets and by contact. Clinical symptoms include
high fever, sore throat, cough, breathlessness, progress to
pneumonia, acute respiratory distress and multisystem
dysfunction. Infectivity rate is high with SARSCoV2 , as a result
many countries are affected. Control measures like are
quarantine, lockdown, regular handwashing, social distancing
have been indicated by WHO and being followed by various
countries. Due unavailability of an effective vaccine and specific
antiviral medication against the virus, only symptomatic
treatment along with the isolation of the patient is being done

Effect of crop regulation practices on spike and corm yield of gladiolus (Gladiolus hybrids Hort.) cv Sarala
Authors: SHYLA R. MARY RUBY
Published: June 2021

Standardization of the crop regulation practices is vital for spike and corm yield maximization in gladiolus (Gladiolus hybrids Hort.). Hence, a field experiment was conducted in factorial randomized block design with three replications at Annamalai University, Annamalai Nagar, during 2019 with the objective to maximize the spike and corm yield of gladiolus by growth regulators and leaf regulation practices done after spike harvest. The gladiolus cv. Sarala was tested with 15 treatment combinations comprising growth regulator treatments of corms viz., 100ppm GA3(G1), 150ppm GA3(G2), 100ppm IAA(G3), 150ppm IAA (G4), and Control(G5)and leaf regulation practicesviz.,harvesting spike leaving all leaves (L1), harvesting spike with three leaves (L2), and clipping leaves at 20cm above the base (L3). The results revealed that the growth regulator treatments, given to corms significantly influenced the growth, flowering, and spike yield of gladiolus. Corm soaking treatment of GA3@150 ppm evinced the best treatment in respect of growth, flowering, and spike yield of gladiolus. Though, the effect of leaf regulation practices on growth and flower yield were insignificant, but their influence in corm yield was significant. The interaction of growth regulator soaking of corms with leaf regulation practices significantly influenced the spike and corm yield. The maximum spike (1.01) and corm yield (1.94) were observed with Corm soaking of GA3@150ppm and harvesting of spikes with three leaves. Leaf regulation by clipping of leaves at 20 cm above the base (L3) had negative influence on corm growth when compared to harvesting of spikes leaving all leaves (L1). The maximum corm diameter (3.25cm) and corm weight (25.4g) were observed with 150 ppm GA3 and harvesting spikes with three leaves. The least corm diameter (2.08cm), number of corms per plant (1.22) and corm weight (17.3g) were recorded with control treatment with cutting leaves at 20cm above the base.

Authors: KUMAR RAJDEO
Published: June 2021

The present study was carried out to characterise the load of heavy metal in the forest soils of Dehradun during various seasons. Surface (0-15 cm) and sub surface (15-30 cm) soil samples were collected from four different sites during summer, monsoon and winter seasons. The results revealed that the maximum Cadmium concentration was recorded in surface (0-15cm) soils and minimum in sub-surface soils (15-30cm). The Cd concentration maximum during summer followed by winter and monsoon. Similar pattern of distribution of chromium was recorded in surface soil. The Chromium content was observed in the order of winter>summer>monsoon in surface soil and summer>winter>monsoon in sub-surface soils. The concentration of Copper in surface soils varied from 3.19 to 0.52mgkg-1 while in sub-surface soil, it varied between 2.25 and 0.57 mg kg-1. The copper concentration was maximum during winter followed by summer and monsoon. The lead concentration was recoeded maximum at site-II and minimum at site-IV whereas, it was recorded maximum during winter and minimum during monsoon. In general, all the heavy metals were found to decrease with soil depth. The concentrations of heavy metal were quite low but their presence in sites makes them potential to increase toxicity in future owing to more environmental degradation.

Published: June 2021

The historical method is a return to pastby collecting evidence ,evaluating it, then scrutinizing it and finallly composing it, so thatthe facts are presented first in a correct presentation in their meaning and in their composition, and until then a conclusion is reached at a group of conclusions with correct scientific evidence. Archeology is very important in historical research, as it is the winess to past ages, and the extent to which ancient civillization and islamic civilization have reached in terms of progress and advancement in all areas of life, as well as they benefit the researcher in history in identifying the degree of professional mastery reached by muslim a rtists in different eras, as archaeologists look to know how civilizations developed, and to know the place and time in wich this development occured, as well as looking into the causes of the changes that made people in the ancient world stop hunting and turn to agreculture, and from researchers are those who research the emergence and development and even the extinction of ancient cities and the economic, social and religious life of these people, such as the maya civilization and others, and in order for archaeologists to achieve these and other goals, they must have scientific research methods and technique, and because archeology it is considred one of the branches of the human sciences as it depends on the basic curricula of the human science in its theoretical part it is based on the analytical, descriptive and historical approach . How do archaeologists apply the historical method in their research and archaeological studies ?.
An Application of Social Network Analysis to Focus Group Discussions: Unobserved Interaction Between Participants and Discussion Topics
Authors: Wu Yu-Lun , Rumble Joy N. , Ruth Taylor K. , Lamm Alexa J. , Ellis Jason D.
Published: June 2021

While focus group discussions have become popular across the communication research field, some researchers have pointed out the importance of studying group interactions within focus groups. However, most researchers used a qualitative approach and mostly explored the interaction between participants or between participants and the moderator. This study claimed there might be a third and unobservable interaction that occurs between participants and structured discussion topics. An affiliation network in social network analysis was applied to investigate this phenomenon among eight groups of existing focus group conversations. By affiliation network data and network visualization, this study demonstrated diverse structures between groups. The interaction between participants and discussion topics was significantly different between at least two groups. The results showed that social network analysis could be a tool to help examine focus group interactions from qualitative data, and the interaction between participants and discussion topics could be a potential third interaction in focus group studies. This study is limited by comparing the mean difference between groups. Future research may examine short- and long-term causal effects of group interaction on participation or attitude changes after focus group discussions.
Intent to Teach: Perspectives from Pre-Service Agricultural Education Teachers
Authors: Eck Christopher J. , Toombs Jessica M. , Robinson J. Shane
Published: June 2021

Historically, less than two-thirds of all newly certified agricultural education students enter the school-based agricultural education (SBAE) teaching profession. Teacher educators must understand preservice teachers’ intention to teach to help fulfill the demand for SBAE teachers. This study examines the motivations to consider a teaching career in SBAE for eight Oklahoma State University pre-service teachers in the early, mid, and late stages of their teacher education coursework. Qualitative methods were employed to describe these individuals’ intention to teach SBAE. Interviews and artifacts in the form of participant autobiographies were collected and analyzed. Intent to teach for these pre-service teachers was tied to the following six categories: expectations of the teaching profession, love of the FFA, need for relevant instruction, community, variety of learning environments, and career intent, which were framed according to the theory of planned behavior (Ajzen, 1991. Additional research should investigate what sustains teachers over time once they enter the profession.
Increasing Boarding Lost Time at Regular Bus Stops during Rainy Conditions: A Case Study

Inclement weather conditions affect the behavior of travelers and transportation system operations. Understanding this influence can help improve operational planning schemes for any mode of transport, especially for buses. One of the factors that can be affected by rainfall is the time expended by a passenger from the moment a bus opens its doors until he/she boards the bus. This time is known as the boarding lost time (BLT); it was first introduced in the last edition of the Transit Capacity and Quality of Service Manual (TCQSM). TCQSM only considers the BLT for bus rapid transit (BRT) stations with more than one berth. Weather conditions are not considered when calculating the current BLT for a BRT system, given the provision of protective shelters over the entire boarding area of such stations. Furthermore, recommendations with regard to the BLT for regular bus stops have not been provided. This paper presents analyses of the BLT for a two-berth regular bus stop under different rainy conditions. The findings demonstrate that the increment in the BLT under heavy rainfall is significantly higher than the difference between the BLTs of Berth 2 and Berth 1 in the absence of rainfall.
The Benefits Of Trait Mindfulness And Flow During A Period of Stressful Preparation

Preparing for an important performance such as a test or job interview can be quite stressful. Considerable evidence reveals that mindfulness meditation (a focus on the present moment) and flow (engaging in activities that fully capture one’s attention) are effective strategies for bolstering well-being in stressful situations, including the wait for uncertain news about a performance outcome. However, less research has examined whether mindfulness and flow buffer well-being while preparing for the performance. Ninety-four law graduates preparing to take the 2019 California bar exam completed a survey assessing trait mindfulness, trait flow, well-being, and coping strategies two weeks prior to the exam. Results revealed that trait mindfulness (controlling for flow) consistently predicted well-being as participants studied for the exam, whereas trait flow (controlling for mindfulness) consistently predicted reduced use of several coping strategies (e.g., bracing, proactive coping). These results suggest that cultivating mindfulness may be an effective way to reduce unpleasant emotions while preparing for a performance, whereas flow may facilitate the use of coping strategies that could indirectly affect well-being.

Introduction

Alzheimer’s disease (AD) is a neurodegenerative disease which presents with an earlier onset age and increased symptom severity. The objective of this study was to evaluate the relationship between regulation of miRNAs and AD.

Material and methods

We completed the bioinformatic analysis of miRNAs-AD studies through multiple databases such as TargetScan, Database for Annotation, Visualization and Integrated Discovery (DAVID), FunRich and String and assessed which miRNAs are commonly elevated or decreased in brain tissues, cerebrospinal fluid (CSF) and blood of AD. All identified articles were assessed using specific inclusion and exclusion criteria.

Results

MiRNAs related to AD of twenty-eight studies were assessed in this study. A wide range of miRNAs were up-regulated or down-regulated in tissues of AD patient’s brain, blood and CSF. 27 differentially dysregulated miRNAs have identified involved in amyloidogenesis, inflammation, tau-phosphorylation, apoptosis, synaptogenesis, neurotrophism, neurons degradation, activates cell cycle entry. Additionally, our bioinformatics analysis identified the top ten functions of common miRNAs in candidate studies. The function of common up-regulated miRNAs primarily target nucleus and common down-regulated miRNAs primarily target transcription, DNA-templated.

Conclusions

Comprehensive analysis of all miRNAs studies reveals cooperation in miRNA signatures whether in brain tissues or in CSF and peripheral blood. More and more studies suggest that miRNAs may play crucial roles as diagnostic biomarkers and/or as new therapeutic targets in AD. According to biomarkers, we can identify the preclinical phase early that provides an important time-window for therapeutic intervention.
Inscripties lezen

This contribution contains brief, introductory guidance on how to read Greek inscriptions. It discusses basic aspects of early Greek scripts, in particular the ‘light-blue’ alphabet of Athens as it was in use until the end of the 5th century BCE. Also included are sections on scriptio continua, punctuation, and numericals. Furthermore, some information is offered on spelling, phonology, morphology and syntax. Finally, the discourse units of a prototypical Athenian decree are analysed and related to underlying political procedures.

De pedagoog als homo clausus

The theoretical pedagogue as a homo clausus

The contributions to Theoretische Pedagogiek (‘Theoretical pedagogy’, eds. B. Spiecker and B. Levering, 1982) predominantly concern the question how theoretical pedagogy contributes to academic pedagogy, and the related question what characterizes this discipline. Some authors defend a specific method, sometimes as attuned to the specific nature of the pedagogical research subject. For example, phenomenological analysis, conceptual analysis, and empirical research pass review. Though each author substantiates the potential contribution of his or her chosen method, (s)he also introduces this method as disqualifying other methods. That does not only leave academic pedagogy a fragmented discipline, it also overstretches the justifiable pretensions of each method, impeding mutual enrichment of these methods at the same time. Other authors contribute by trying to ground the discipline and its methods in purported unique anthropological characteristics of pedagogical phenomena. However, they cannot solve the problems either, because they leave us again with mutually exclusive approaches and a fragmented discipline. It even becomes questionable whether we can speak of ‘one’ discipline at all, as subsequent authors keep writing as a ‘homo clausus’, culminating in the seeming incompatibility of pedagogy as a behavioral science versus pedagogy as a social science. After reading this collection, one wonders whether a more question-guided, interdisciplinary approach, open to mutual enrichment of various methods would not better serve the discipline.

Building landscapes

A drawing by artist Jan Hoynck van Papendrecht (1858-1933) can be understood as a view of the f irst buildings along Amsterdam’s Van Eeghenstraat, as seen from his rear window. The late 19th-century method of raising polder meadows for urban expansion is also clearly visible on a hitherto mislocated drawing by Gerrit Haverkamp (1872-1926) of a building site in Amsterdam Oud-West. The chronological development of raising building sites can still be acknowledged from height differences in Amsterdams urban fabric. Building landscapes are rather underexposed in Dutch historical geography as a seemingly temporary situation. However, they are an intrinsic and sometimes longer-lasting part of the landscape’s biography and deserve more attention than they have received until now.
A STDP Rule that Favours Chaotic Spiking over Regular Spiking of Neurons
Authors: Aoun Mario Antoine
Published: June 2021

We compare the number of states of a Spiking Neural Network (SNN) composed from chaotic spiking neurons versus the number of states of a SNN composed from regular spiking neurons while both SNNs implementing a Spike Timing Dependent Plasticity (STDP) rule that we created. We find out that this STDP rule favors chaotic spiking since the number of states is larger in the chaotic SNN than the regular SNN. This chaotic favorability is not general; it is exclusive to this STDP rule only. This research falls under our long-term investigation of STDP and chaos theory.
Effect Man-In the Middle on the Network Performance in Various Attack Strategies
Authors: Alodat Iyas
Published: June 2021

In this paper, we examined the effect on network performance of the various strategies an attacker could adopt to launch Man-In The Middle (MITM) attacks on the wireless network, such as fleet or random strategies. In particular, we're focusing on some of those goals for MITM attackers - message delay, message dropping. According to simulation data, these attacks have a significant effect on legitimate nodes in the network, causing vast amounts of infected packets, end-to-end delays, and significant packet loss.
An investigation into the accounting treatment of property, plant and equipment at public higher education institutions in South Africa
Authors:   , Kheru Sunildutt
Published: June 2021

Property, plant and equipment (PPE) constitute a significant portion of total assets of South African public higher education institutions. It is therefore important to keep proper records of the assets and to account for them accurately in the Annual Financial Statements. The aim of this study therefore was to investigate the accounting treatment of property, plant and equipment at public higher education institutions (PHEIs) in South Africa. The following objectives were addressed in this study, to: determine how assets are classified; find out how asset transactions are recorded; and to determine the accounting treatment of assets in terms of cost, depreciation, impairment and disposal. Based on the International Financial Reporting Standards, this study used a mixed-methods research approach to collect data regarding the accounting treatment of PPE at the 23 PHEIs in South Africa. Analysis of results indicated that some institutions: apply different useful lives for the same asset classes; use threshold amounts for the recording and depreciating of assets; use the same value for the recording and depreciating of assets while others record at one value but depreciate at a higher value; and depreciate PPE at different rates as they apply varying useful life to different asset classes. This study also found that while some institutions do impairment testing on an annual basis, others do not, as they do not have a policy in place for impairment testing. Given that the activities or business of educational institutions are similar in nature, this study recommends that PHEIs need to apply consistent recording of assets in terms of their useful life as the useful life of an asset has direct correlation with the surplus or deficit of an institution. This study makes further recommendations regarding the accounting treatment of PPE at PHEIs in South Africa based on the findings of this study. Suggestions for further research are also presented.
