Though COVID-19 caught healthcare authorities worldwide off guard, several countries successfully dampened the morbidity and mortality curve by imposing strict biosecurity protocols. We would like to observe the effect of healthcare policies enforced in correlation to the formation of new clusters during early phases of the pandemic, thereby providing statistical justification for laws enforced by authorities. With access to medical records from Udayana University Hospital, a tertiary COVID-19 referral health center, we then observe epidemiological data of patients admitted and their admission date in correlation to dates where major changes in national COVID-19 protocols were established. We found a double distinctive curve that is mainly made of two distinct demographic groups: migrant workers and private employees. We found that during March 2020, when strict travel protocols are yet to be imposed, the viral introduction was mostly carried by returning migrant workers. Sporadic cases emerged, though soon vanishing due to the enforcement of quarantine protocols. Subsequently, in June 2020, a work-from-office setting was adopted, where some offices perform at a capacity higher than allowed. This incites the formation of new office-linked clusters. After this period, no recognizable pattern found due to massive local transmission affecting all layers of society. However, it can be concluded that COVID-19 law does shape the curve, and strict protocols may end the pandemic sooner.

Pigeonpea (Cajanus cajan (L.) Millsp.) is a grain legume crop from the tropics and subtropics cultivated for its highly nutritious seeds. Relatively low yields have been observed among African accession with little information on germplasm performance. Therefore, it is needed to identify resilient germplasm, varieties or accessions to improve agronomic performance. This study assessed the morphological variability among selected accessions of Nigerian pigeonpea to identify potential lines for agronomic improvement. A total of 52 Nigerian pigeonpea accessions were evaluated using 10 qualitative and 13 quantitative morphological traits. They were planted using a completely randomised design. Yield performance, trait correlation, principal component (PC), and cluster analysis were used to identify potential breeding lines. The study revealed a wide variability among pigeonpea accessions with both qualitative and quantitative traits. The 52 pigeonpeas were clustered into three major groups. Four principal components with eigenvalue > 1 accounted for 68.95% of the total variation observed. The first PC accounted for 30.13% with yield components, which include days to 50% flowering, plant height, days to 50% maturity, and vigour at 50% flowering as major contributors. These traits also showed strong significant correlations between themselves. Hence, they can be improved simultaneously. The study identified several potential accessions based on performance that can be selected for multilocational evaluations and crop improvement.

Published: June 2023

Abstract
Surface water and groundwater are polluted with pharmaceuticals, detergents, pesticides, and many other substances. Application of ferrates seems to be a perspective option for wastewater treatment as ferrates are not only powerful oxidizing agents but also an excellent disinfecting and coagulating agents decomposing many stable inorganic, organic, and biological compounds. Final products of their decomposition do not include carcinogenic or toxic products. In this paper, stability of electrochemically prepared potassium ferrate encapsulated in packaging materials printed on a 3D printer was monitored. In the experiment, electrochemically prepared potassium ferrate with different purity (21.4 %, 63.5 % and 67.3 %) was used. Stability of potassium ferrate was monitored for one month and that of other ferrates for three months. Different storage conditions of ferrate samples were also compared. Storage conditions had a significant influence on the ferrate stability.
Different susceptibility to body deformities in juveniles of 13 European species (Cypriniformes: Pisces) intensively fed dry formulated diet under controlled conditions
Authors: Sikorska Justyna , Wolnicki Jacek , Kamiński Rafał 
Published: June 2023

Abstract
The aim of this study was to compare the susceptibility to body deformities in juveniles of 13 common European cypriniform fish, caused by intensive feeding with the same commercial dry diet administered at 25°C according to a similar feeding schedule. The final share of individuals with body malformations differed considerably among species and was 0.0-87.0%. Unaffected by the intensive feeding were only Barbus barbus (L.), Chondrostoma nasus (L.), Cyprinus carpio L. and Leuciscus aspius (L.). They can be safely fed with the highest rations of dry diet constituting 2,5-3% of fish biomass daily. Most of the species exhibited body malformations in a short time of only 20-30 days of feeding. Abramis brama (L.), Leuciscus idus (L.), Leuciscus leuciscus (L.), Scardinius erythrophthalmus (L.), Carassius carassius (L.), Rutilus rutilus (L.) and Squalius cephalus (L.) proved to be highly prone to body deformities – daily ration of feed 2.5% of fish biomass resulted in high incidence of malformed individuals after 60 days of feeding (50-87%). For these species safe daily ration of a dry diet should not exceed 2% of total fish biomass. Tinca tinca (L.) and Vimba vimba (L.) showed medium susceptibility to body deformities (11 and 24%, respectively). They can be fed with the daily ration of a dry diet about 2,3% of fish biomass. Some regularities connected with different susceptibility to fish body deformities are discussed in the paper.

Authors: Dumitrescu Laura , Bliuc Irina , Baran Irina , Pescaru Radu-Aurel , Parincu Paul-Dorian 
Published: June 2023

Abstract
The built environment, through the consumption of energy from non-renewable sources and the associated CO2 emissions, as well as through the production of waste throughout its life cycle and the effects of soil and water degradation, contributes significantly not only to the phenomenon of climate change, but also to the irreversible degradation of the natural environment. The concept of regenerative design provides a framework for a holistic approach to these issues in order to identify the most effective remedies, proposing the restoration and regeneration of the global socio-ecological environment through a system of engineering practices suitable to the specific context. The defining aspects of the regeneration applied in the buildings sector refer to the architecture and inserting in the natural environment ensuring a healthy and well-being indoor environment, reducing to zero the consumption of energy from non-renewable sources and promoting renewable energy sources, minimizing carbon footprint by rational use of materials and waste management throughout the life cycle.
Determination of the Physical-Mechanical Characteristics of Non-Cohesive Soils Stabilized with Fly Ash (Part II)
Authors: Iriciuc Silviu Cristian , Gimiga Gelu Răzvan , Gălușcă Izabela Narciza 
Published: June 2023

Abstract
The unprecedented scale of road network development programs in our country requires the consumption of materials (natural aggregates, binders), often non-renewable and expensive, which are difficult to secure from traditional sources. Alternative solutions for the replacement of natural aggregates, binders, as viable alternatives to classical technologies, the adoption and continuous development of recycling technologies are concerns of researchers, designers and road builders. So, the stabilized mixtures successfully form the sub-grade layers of the rigid road structures or both the sub-grade layers and the base layers of the semi-rigid structures (Zarojanu, 1976).
Compared to traditional, untreated, thick foundations, the stabilized foundations, consisting of a series of thinner layers (assizes), with considerably increased rigidity, ensure a more judicious distribution of traffic loads for lower overall thicknesses of the road structure (Boboc, 1995).

Published: June 2023

Abstract
A current global effort is being made in order to find solutions that will limit global warming. The building sector is responsible for the highest share of total energy consumption, which requires the continuous development of strategies to increase buildings energy efficiency. Considering the high share of emissions generated by buildings, improving buildings energy performance can significantly slow down global warming.
A key point in developing strategies to reduce energy consumption and making more accurate forecasts of the evolution of global warming is to determine the actual energy consumption generated by the use of buildings, which in some cases may differ from the theoretical one. In order to determine the actual energy consumption, with high accuracy, determinations in situ of the thermal resistance of the building elements that form the envelope, are essential.
The article presents the main methods for determining the thermal resistance of building elements in situ, factors influencing the accuracy of the results, and recommendations for the use of methods to reduce the risk of errors.

The role of personality traits and perceived threat on COVID-19 vaccine acceptance among undergraduates is relatively scarce. The study investigated the role of personality traits and perceived threat on COVID-19 vaccine acceptance among 374 (age = 18-28 years, M =23.23 years, SD = 2.57 years) undergraduates in Obafemi Awolowo University, Ile-Ife, Nigeria. A cross-sectional survey design was utilized. A self-administered questionnaire was used to gather information about socio-demographics, HEXACO personality traits, perceived threat and COVID-19 Vaccine acceptance. Results showed a significant influence of personality traits on COVID-19 vaccine acceptance. Findings also revealed that perceived threat significantly predict COVID-19 vaccine acceptance among undergraduates. Result further showed that there was a significant influence of religion on COVID-19 vaccine acceptance (t (372) = −2.13, p = .034, 95% CI (−6.44, −.25), d = 0.22.) These results emphasize the importance of HEXACO personality traits and perceived threat when considering program targeted at COVID-19 vaccine acceptance among undergraduates.
Dissimilarity measure between intuitionistic Fuzzy sets and its applications in pattern recognition and clustering analysis
Authors: Rani V. , Kumar S. 
Published: June 2023

Abstract
In this study, in order to prevent information loss, we propose two dissimilarity measures between intuitionistic fuzzy sets (IFSs), which consider membership and non-membership degree and IFSs is farther extension of Fuzzy sets (FSs). Additionally, we have examined the characteristics of the proposed metrics to confirm their validity. We then conducted a series of experiments, including numerical experimentation, pattern recognition, and clustering analysis, to evaluate the efficacy of these metrics. The comparative outcomes illustrate that our dissimilarity metrics are more straightforward, easy to understand, and superior to the majority of the existing methods.
