Detection and Classification of Concrete Patches by Integrating GPR and Surface Imaging
Authors: Cheng Peng , Krogmeier James V. , Bell Mark R. , Li Joshua , Yang Guangwei
Published: October 2021

This research considers the detection, location, and classification of patches in concrete and asphalt-on-concrete pavements using data taken from ground penetrating radar (GPR) and the WayLink 3D Imaging System. In particular, the project seeks to develop a patching table for “inverted-T” patches. A number of deep neural net methods were investigated for patch detection from 3D elevation and image observation, but the success was inconclusive, partly because of a dearth of training data. Later, a method based on thresholding IRI values computed on a 12-foot window was used to localize pavement distress, particularly as seen by patch settling. This method was far more promising. In addition, algorithms were developed for segmentation of the GPR data and for classification of the ambient pavement and the locations and types of patches found in it. The results so far are promising but far from perfect, with a relatively high rate of false alarms. The two project parts were combined to produce a fused patching table. Several hundred miles of data was captured with the Waylink System to compare with a much more limited GPR dataset. The primary dataset was captured on I-74. A software application for MATLAB has been written to aid in automation of patch table creation.

Authors: Kondo Lorhan Sohaky de Oliveira Duda , Mendonça Bruno de Azevedo , Smaira André de Freitas , Matias Paulo
Published: October 2021

Capture-The-Flag (CTF) são competições voltadas à área de segurança. Mesmo sendo organizadas por especialistas da área, as plataformas utilizadas para a realização dos eventos estão sujeitas a vulnerabilidades, assim como qualquer outro software. Embora a literatura tenha proposto o protocolo NIZKCTF (Non-Interactive Zero-Knowledge Capture the Flag), em que os participantes enviam provas de conhecimento zero de que possuem as respostas aos desafios da competição, a implementação desse protocolo carece de quesitos de usabilidade que só foram percebidos com sua utilização ao longo dos anos. Este trabalho discute lições aprendidas e adaptações ao NIZKCTF realizadas pelos organizadores do Pwn2Win CTF de 2017 a 2021.

Fabricantes de microcontroladores possuem soluções próprias para uma atualização segura e confiável, porém cada solução possui particulares para uso. Este trabalho apresenta uma solução genérica para atualização segura e confiável de firmware de microcontroladores. Foi realizada uma implementação referência com o microcontrolador STM32L562QE de forma a validar a solução proposta e para demonstrar que é possível obter atualização segura e confiável sem depender de soluções proprietárias dos fabricantes de microcontroladores.
Evidence Sensitivity as a Heuristic for Doubt
Authors: Pinillos N. Ángel ,   Philosophy Documentation Center
Published: October 2021

Sensitivity-type principles are prominent in epistemology. They have the promise to explain our intuitive and considered reactions to a wide range of important cases in everyday life, science and philosophy. Despite this promise, philosophers have raised a number of very serious objections to the principles. Accordingly, I propose a different type of sensitivity account which, I believe, gets around these serious objections. An important feature of the new approach is that the principle I propose need not be true. Rather, it should be understood as a cognitive heuristic that tells us when something is not known—a type of doubt. A second feature is that the principle does not care about what one’s belief would be like in counter-factual situations. Instead, it cares about what the bases or causes for the belief would be like in those situations.
Four new genera of the Ceratonotus group (Copepoda, Harpacticoida), including the description of two new species
Authors: GEORGE Kai Horst
Published: October 2021

In the framework of an ongoing extensive phylogenetic evaluation of the Ceratonotus group (Copepoda, Harpacticoida, Cletodidae), Poropsyllus menzelae gen. et sp. nov. from the sublittoral of south-western Cyprus (eastern Mediterranean Sea) and Paratouphapleura aaroni gen. et sp. nov. from the western Weddell Sea (Antarctica) are described. Both new species fit the autapomorphies of the Ceratonotus group but cannot be assigned to any of the genera so far known. Instead, each new species presents a set of derived characters that justify their placement in new genera, Poropsyllus gen. nov. and Paratouphapleura gen. nov., respectively. Furthermore, a comparison of the species placed in Ceratonotus Sars revealed that because of exclusive morphological deviations, Ceratonotus concavus Conroy-Dalton, C. steiningeri George, C. tauroides George, and C. vareschii George should be excluded from Ceratonotus and transferred to a new monophylum, Tauroceratus gen. nov. Likewise, Polyascophorus monoceratus George, Wandeness & Santos is characterized by several apomorphies that justify its transfer from Polyascophorus to a new taxon, Pseudopolyascophorus gen. nov. The Ceratonotus group is therefore increased to 31 species assigned to 13 genera. The systematic modifications conducted and resulting phylogenetic consequences are discussed in detail.

Published: October 2021

Afin d’évaluer la capacité d’accueil des ripisylves pour la biodiversité, nous proposons un nouvel indice tenant compte des dimensions longitudinale et transversale de l’hydrosystème : l’Indice de Biodiversité et de Connectivité des Ripisylves (IBCR). Constitué de 15 facteurs renseignant des critères liés au peuplement et à sa gestion, au contexte environnant, aux perturbations/pressions et à la connectivité, l’IBCR est un nouvel outil qui fournit aux gestionnaires des cours d’eau des éléments concrets pour diagnostiquer rapidement l’état écologique des ripisylves et orienter la gestion pour la conservation de la biodiversité associée aux linéaires boisés riverains. Pour illustrer l’utilité de cet indice, nous avons étudié la réponse des communautés d’oiseaux aux facteurs de l’IBCR, en distinguant les espèces des milieux forestiers, agricoles, aquatiques et bâtis/rocheux. Nos résultats montrent que les cortèges d’oiseaux répondent de façon assez cohérente aux valeurs de l’IBCR, avec une augmentation de la richesse en espèces d’oiseaux des milieux forestiers avec l’augmentation du score moyen de l’indice. En revanche, les ripisylves ayant un indice de faible score, c’est-à-dire davantage dégradées et déconnectées, favorisent surtout la présence d’espèces d’oiseaux des milieux agricoles. Dans l’ensemble, ces résultats soulignent l’intérêt de l’IBCR pour évaluer rapidement les principales caractéristiques des boisements riverains et les capacités d’accueil associées, au moins pour les communautés d’oiseaux.

Desaproprio a hora ao redor deste artigo: notações pessoais sobre proposições de Guilherme Vaz
Authors: Leão Daniel Velasco
Published: October 2021

Este artigo aborda três proposições artísticas realizadas por Guilherme Vaz entre 1969 e 1970 para o Salão da Bússola no Museu de Arte Moderna do Rio de Janeiro, a mostra sequencial Agnes Dei na Petite Galerie do Rio de Janeiro e a exposição coletiva Information no Museu de Arte Moderna de Nova York. Realizadas no período correspondente à sua primeira vivência na cidade do Rio de Janeiro, marcada por encontros e contágios com Artur Barrio, Thereza Simões, Nelson Pereira dos Santos e Frederico Morais, essas proposições se dão pelo meio de palavras em três estados distintos: comunicadas pelo corpo do próprio artísta, escritas em pequenos bilhetes afixados na galeria ou reproduzidas por um alto-falante. Minha metodologia consiste na introdução deste período a partir de um breve arco artístico-biográfico, seguida pela descrição de suas obras a partir de seu contexto de realização e do diálogo crítico com textos e obras artísticas, e concluída por reflexões ensaísticas a respeito das especificidades e efeitos dos diferentes estados voco-verbais das palavras nestas três proposições.

Não eu: Rosalind Krauss e as ironias de Jasper Johns
Authors: Friques Manoel Silvestre
Published: October 2021

O texto propõe uma leitura dos dois escritos da crítica estadunidense Rosalind Krauss sobre a obra do pintor Jasper Johns. Para tal, parte-se das perspectivas antitéticas da autora sobre os quadros de Johns. De um lado, Krauss analisa alguns quadros sob a chave greenbergiana. De outro lado, a autora recupera a filiação duchampiana para investigar as táticas pictóricas de Johns. A indagação que surge daí é a seguinte: em que medida que este segundo eixo de análise é complementar ao primeiro? A resposta sugerida é encontrada no texto “Não Eu”, do dramaturgo – e um dos parceiros de Johns – Samuel Beckett.

Implementation and applications of harvest fleet route planning
Authors:   , Henriksen Andrés Villa
Published: October 2021

In order to support the growing global population, it is necessary to increase food production efficiency and at the same time reduce its negative environmental impacts. This can be achieved by integrating diverse strategies from different scientific disciplines. As agriculture is becoming more data-driven by the use of technologies such as the Internet of Things, the efficiency in agricultural operations can be optimised in a sustainable manner. Some field operations, such as harvesting, are more complex and have higher potential for improvement than others, as they involve multiple and diverse vehicles with capacity constraints that require coordination. This can be achieved by optimised route planning, which is a combinatorial optimisation problem. Several studies have proposed different approaches to solve the problem. However, these studies have mainly a theoretical computer science perspective and lack the system perspective that covers the practical implementation and applications of optimised route planning in all field operations, being harvesting an important example to focus on. This requires an interdisciplinary approach, which is the aim of this Ph.D. project. The research of this Ph.D. study examined how Internet of Things technologies are applied in arable farming in general, and in particular in optimised route planning. The technology perspective of the reviewing process provided the necessary knowledge to address the physical implementation of a harvest fleet route planning tool that aims to minimise the total harvest time. From the environmental point of view, the risk of soil compaction resulting from vehicle traffic during harvest operations was assessed by comparing recorded vehicle data with the optimised solution of the harvest fleet route planning system. The results showed a reduction in traffic, which demonstrates that these optimisation tools can be part of the soil compaction mitigation strategy of a farm. And from the economic perspective, the optimised route planner of an autonomous field robot was employed to evaluate the economic consequences of altering the route in selective harvesting. The results presented different scenarios where selective harvest was not economically profitable. The results also identified some cases where selective harvest has the potential to become profitable depending on grain price differences and operational costs. In conclusion, these different perspectives to harvest fleet route planning showed the necessity of assessing future implementation and potential applications through interdisciplinarity.
Les normes sociales collectives au sein des groupes de soutien d’apprentissage en famille
Authors: Dumond Marine , Brabant Christine
Published: October 2021

L’apprentissage en famille (AEF) est une option éducative légale encadrée par le ministère de l’Éducation du Québec (MEQ). Son suivi par l’État présente plusieurs défis, notamment concernant l’appréciation de l’expérience éducative. Dans une perspective de gouvernance réflexive, les groupes de soutien locaux et auto-organisés de familles, par leur position intermédiaire et collective, pourraient jouer un rôle de suivi complémentaire et mieux accepté que celui des autorités ministérielles. Au moyen d’entrevues de groupe et d’analyse de documents, les normes sociales collectives explicites et implicites de deux groupes de soutien québécois, portant sur la socialisation, l’engagement parental et l’enrichissement de l’expérience éducative, sont décrites. Leurs visées communes avec le cadre juridique en place suggèrent que le groupe de soutien peut être un outil facilitant dans la gouvernance de l’AEF.
Les préoccupations d’enseignantes dans la mise en place d’une communauté d’apprenantes et d’apprenants au primaire
Authors: Miville Anne-Marie , Hamel Christine , Viau-Guay Anabelle
Published: October 2021

Concevoir la classe en communauté d’apprenantes et d’apprenants est une avenue porteuse pour permettre aux élèves de faire des apprentissages signifiants (Brown et Campione, 1995). Les valeurs promues par celle-ci peuvent toutefois être difficiles à mettre en place en regard de la complexité de leur tâche. Cette étude de cas vise à décrire les préoccupations et les interventions de deux enseignantes du primaire qui font émerger des valeurs de la communauté au sein de leur groupe-classe sur une période de trois mois en contexte de coenseignement. Avec le cadre théorique du cours d’action de Theureau (2006), nous avons analysé leur pratique en utilisant diverses traces (p. ex. : vidéoscopies, travaux d’élèves, planificateurs, etc.). Nos résultats illustrent que les préoccupations des enseignantes sont certes variées et évolutives dans le temps et mettent en lumière l’éventail d’interventions pédagogiques qu’elles déploient en écho à ce qui les préoccupe quant à la mise en place des valeurs de la communauté.

Published: October 2021

Les recherches en éducation s’enracinent profondément dans la réalité complexe des phénomènes d’enseignement et d’apprentissage, convoquant les acteurs de la recherche et de l’éducation à appréhender cette complexité dans un travail commun. L’inscription de ce travail dans une perspective participative ou collaborative nécessite une intelligibilité accrue des processus collaboratifs à l’oeuvre et des défis qu’ils posent aux différents acteurs. Nous proposons dans cet article un modèle théorique des processus de collaboration fondé sur une construction épistémologique et méthodologique croisant des cadres théoriques issus de l’anthropologie, de la psychologie, de la philosophie, de la didactique et des sciences du langage, avec pour ambition de créer une meilleure intelligibilité des processus à l’oeuvre dans les recherches participatives en éducation.

L’objectif de cet article est d’analyser les effets de ce virage en matière de valorisation des productions en sciences sociales, lors des évaluations de laboratoire comme sur les pratiques scientifiques des principaux intéressés. Les rapports d’évaluation de six laboratoires et douze entretiens réalisés auprès d’enseignants-chercheurs montrent que le nouveau guide des produits de la recherche altère en profondeur leur activité. Il est appliqué avec un zèle qui renforce la centralité duScimago Journal Ranking, devenu outil normatif d’appréciation. Les enseignants-chercheurs concernés élaborent des stratégies duales pour composer avec ces nouvelles exigences tout en se ménageant des espaces d’expression et de reconnaissance alternatifs.
Novel Heterozygous Variants in the HLA-DRB1 Gene in a Saudi Family With Early-Onset Familial Multiple Sclerosis: Therapeutic Failure and Success
Authors: Algahtani Hussein , Shirah Bader , Khafaji Randa , Algahtani Sarah
Published: October 2021

Multiple sclerosis (MS) is a chronic neurodegenerative disease that affects the central nervous system. Familial MS is arbitrarily defined as a type of MS that runs in families with 1 or more first- to third-degree relatives in addition to the index case affected by MS. The aim of this article is to report a unique case of familial MS from Saudi Arabia with 2 novel variants in the HLA-DRB1 gene that may contribute to the pathogenesis. We observed an unfavorable response to interferon therapy and successful treatment using fingolimod therapy. This observation needs further study, including whether this lack of response is specific to interferon treatment or possibly a chance occurrence. This family work-up illustrates the importance of genetic testing in identifying variants associated with familial MS, especially if more than 2 members of the same family are affected. Although this genetic tool is used mainly for research purposes, it had clinical implications for our patient, including the appropriate selection of disease-modifying therapy and prognostic counseling. Further large-scale studies are needed to expand the genetic spectrum of familial MS with clinical and pharmacologic correlation.
Novel trends in the symphonic work of Soviet composers of the 1960s and B. Tishchenko's Symphony No.3. Part 1
Authors: Serov Iurii Eduardovich
Published: October 2021

The subject of this research is the period of Russian symphonic music of the 1960s – a new generation of composers, the “Sixtiers”, who brought remarkable artistic achievements and modern musical language. The author dwells on several key symphonic works by R. Shchedrin, S. Slonimsky, E. Denisov, Y. Falik, A. Schnittke, N. Karetnikov, and L. Prigozhin, who made an immense contribution to the revival of the Russian music culture. Special attention is given to Boris Tishchenko’s Symphony No.3, which encompasses the key trends of modern music into its stylistic orbit and opened new musical horizons. The scientific novelty lies in the fact that this article is first to examine the outstanding composition Symphony No.3 by B. Tishchenko in the context of stylistic and linguistic novelties of the 1960s. Detailed analysis is conducted on the role and place of the youngest out of the “Sixtiers” – the prominent Russian symphonist of the XX century Boris Ivanovich Tishchenko (1939–2010) – in the struggle for “new music”. The conclusion is made that Tishchenko became one of the leaders in the revival of the Russian symphonic style of the late XX century, and his Symphony No.3 fully reflected the rigorous pursuits of the entire generation of Soviet composers.

Published: October 2021

This study examines how gender shapes the experiences of internationally educated Chinese women academics in obtaining academic positions in higher education institutions in China. Drawing on feminist theories and using a qualitative narrative method, this paper investigates women’s
experiences in applying and interviewing for academic jobs in China. The findings demonstrate various challenges women encounter, including gender-based discrimination, arbitrary evaluation criteria, and institutional inertia, and illustrate women’s subjectivity in pursuing academic
careers. This study exposes the limitations of the statistical understandings of gender parity and the negative effects of neoliberal measurability, and suggests measures for institutions to promote gender equity.

A total of 1006 students from three public and two private universities in Indonesia participated in the study of multiple goals profiling in the Indonesian context. Four multiple-goal clusters, with learning, performance approach, performance avoidance, and work avoidance goals as
clustering variables, were educed. Learning goals correlated positively with both performance approach and performance avoidance clusters, and negatively to work avoidance goals. Performance goals correlated positively with both performance avoidance and work avoidance goals. Learning, performance
approach and performance avoidance goals correlated positively with self-efficacy. These clusters were further examined in relations to attributions, self-efficacy, theories of intelligence, religiosity, racial/ethnic identity, and academic performance.
Dynamic dichotomy of accumbal population activity underlies cocaine sensitization
Authors: van Zessen Ruud , Li Yue , Marion-Poll Lucile , Hulo Nicolas , Flakowski Jérôme , Lüscher Christian
Published: October 2021

Locomotor sensitization (LS) is an early behavioral adaptation to addictive drugs, driven by the increase of dopamine in the Nucleus Accumbens (NAc). However, the effect on accumbal population activity remains elusive. Here, we used single-cell calcium imaging in mice to record the activity of dopamine-1-receptor (D1R) and dopamine-2-receptor (D2R) expressing spiny projection neurons (SPNs) during cocaine LS. Acute exposure to cocaine elevated D1R SPN activity and reduced D2R SPN activity, albeit with high variability between neurons. During LS, the number of D1R and D2R neurons responding in opposite directions increased. Moreover, preventing LS by inhibition of the ERK signaling pathway decreased the number of cocaine responsive D1R SPNs, but had little effect on D2R SPNs. These results indicate that accumbal population dichotomy is dynamic and contains a subgroup of D1R SPNs that eventually drives LS. Insights into the drug-related activity dynamics provides a foundation for understanding the circuit-level addiction pathogenesis.

Published: October 2021

Background

Lack of infrastructure for disposal of effluents in industries leads to severe pollution of natural resources in developing countries. These pollutants accompanied by solid waste are equally hazardous to biological growth. Natural attenuation of these pollutants was evidenced that involved degradation by native microbial communities. The current study encompasses the isolation of pesticide-degrading bacteria from the vicinity of pesticide manufacturing industries.

Methods

The isolation and identification of biodegrading microbes was done. An enrichment culture technique was used to isolate the selected pesticide-degrading bacteria from industrial waste.

Results

Around 20 different strains were isolated, among which six isolates showed significant pesticide biodegrading activity. After 16S rRNA analysis, two isolated bacteria were identified as Acinetobacter baumannii (5B) and Acidothiobacillus ferroxidans, and the remaining four were identified as different strains of Pseudomonas aeruginosa (1A, 2B, 3C, 4D). Phylogenetic analysis confirmed their evolution from a common ancestor. All strains showed distinctive degradation ability up to 36 hours. The Pseudomonas aeruginosa strains 1A and 4D showed highest degradation percentage of about 80% for DDT, and P. aeruginosa strain 3C showed highest degradation percentage, i.e., 78% for aldrin whilst in the case of malathion, A. baumannii and A. ferroxidans have shown considerable degradation percentages of 53% and 54%, respectively. Overall, the degradation trend showed that all the selected strains can utilize the given pesticides as sole carbon energy sources even at a concentration of 50 mg/mL.

Conclusion

This study provided strong evidence for utilizing these strains to remove persistent residual pesticide; thus, it gives potential for soil treatment and restoration.

Published: October 2021

El escándalo global de los abusos sexuales en entornos eclesiales está generando una reflexión en torno a los motivos que lo convierten en un problema estructural de la Iglesia. A pesar de esta repercusión social, aún siguen en segundo plano los abusos cuyas víctimas son adultos, especialmente mujeres, las conductas abusivas que no afectan a la dimensión sexual y aquellos que se realizan dentro de las instituciones eclesiales. Este artículo pretende reunir estos tres aspectos, aún silenciados, para sacar a la luz el problema del abuso de poder en la Vida Consagrada, especialmente en la femenina. Para ello, se analizarán algunos de los elementos que pueden derivar con facilidad en un uso abusivo del poder y que confluyen en esta vocación cristiana.

Published: October 2021

Aims: The aim of this study is to evaluate the content of phenolic compounds, antioxidant and 15-lipoxygenase inhibition effects of methanolic extract and its fractions of Daniellia. oliveri stem bark.

Place and Duration of Study: The work was carried out in the Department of Traditional Pharmacopoeia and Pharmacy (MEPHATRA / PH) of the Institute for Research in Health Sciences (IRSS) and LABIOCA from Université Joseph KI-ZERBO in Ouagadougou between February 2018 and June 2019

Methodology: The phytochemical screening and phenolic content were determined by the methods described in the literature. Antioxidant activity was determined by DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,20-azinobis 3-ethylbenzoline-6-sulphonate), FRAP (ferric reducing antioxidant power), and lipid peroxidation (LPO). The anti-inflammatory activities were measured on the ability of the extract to inhibit the activity of enzymes such as 15-lipoxygenase

Results: Phytochemical screening revealed the presence of flavonoids, tannins, saponins, anthocyanosides, triterpenes and sterols. The extract and its fractions showed a good content of phenolic compounds with values ranging from 773.97 ± 22.91 to 505.51 mg EAG / g for total polyphenols; from 24.38 ± 0.34 to 12.04 ± 0.08 mg EQ / g in total flavonoids, 311.65 ± 6.70 to 221 ± 0.52 mg EC / g in condensed tannins; 681.81 ± 3.97 to 421.29 ± 8.73 mg EUA / g in total triterpenes and from 280.29 ± 21.72 to 222.04 ± 20.99 mg EC / g for total sterols. The methanol fraction showed the best antioxidant activity as well as the best inhibitory effect on 15-lipoxygenase activity.

Conclusion: These results showed that Daniellia. oliveri possessed an antioxidant power, an inhibitory effect of 15 lipoxygenase. Daniellia oliveri could be used in the management of inflammatory pathologies and oxidative stress.
Effect of Bioslurry from Fixed Dome and Tubular (Flexi) Biodigesters on Selected Soil Chemical Properties, Maize (Zea mays) Growth, Yield and Quality

Published: October 2021

Agricultural utilization of bioslurry plays a critical role in soil conditioning and hence crop production. It also reduces greenhouse gas emissions thus mitigating climate change. Although the effect of bioslurry on growth and yields is well researched, that of different biodigester types is under-researched. Therefore, a study was carried out in Waruhiu Agricultural Training Centre, Githunguri sub-county, Kiambu county in Kenya, to investigate the effect of bioslurry from flexi and dome biodigesters on soil chemical properties, maize growth, yield and grain quality. Treatments were laid out in a Randomized Complete Block Design (RCBD) and replicated three times. The treatments were bioslurry from both Fixed Dome and Flexi biodigesters, applied separately at a rate of 400mls per hill as basal and top dress fertilizer. Planting was done during the 2019 short and 2020 long rains, using Duma 43 maize variety. The agronomic (germination percentage, number of leaves, leaf width, leaf length, plant height) and productivity data (stalk, stovers, grain yields and grain quality) were subjected to analysis of variance (ANOVA) through Proc general linear model (GLM) procedures. Mean separation was done using least square means (LS-Means). Results showed an increase in soil pH, total N and OC, exchangeable P, K, Mn and Na in both biodigester types. Total N and OC were higher in Dome treated soils by 38.89% and 37.00%, while in Flexi, it was 16.67% and 16.00% respectively. Exchangeable P and K was higher in Flexi treated soils with a 38.57% and 50.00% increase while in Dome it 37.86% and 47.22% respectively. Magnesium and Zn decreased after treatment by 34.30% and 22.59% in Dome while Flexi had 33.23% and 31.79% increase. Exchangeable Fe and acidity decreased in Dome but increased in Flexi treated soils. No statistical differences were observed on growth and yield parameters but Dome registered higher grain yields by 9.4% and 6.3% for short and long rains respectively. Flexi treated soils registered higher values in most grain nutrient content such as K, Fe, Cu, Mn and Zn in short rains and P, Ca, Fe, Cu, Mn and Zn in the long rains. Bioslurry from both biodigester types variably increased the evaluated soil chemical properties but decreased Mg and Zn. Despite the numerical differences noted between bioslurry from both biodigester types on maize growth and yield, there was no significant difference (p≤.05). However, Dome bioslurry increased N, OC and maize grain yield more while exchangeable P and K and most of the grain nutrient content were higher in Flexi treated soils. Therefore, bioslurry from either biodigester type can be used in enhancing soil conditions, growth, yield and quality of maize. However, a long-term experiment is required validate the findings.

The experiment of the present research work was conducted during summer season of 2018-19 and 2019-20 at Horticulture Research Farm-I, Department of Horticulture, School of Agricultural Sciences and Technology, Babasaheb Bhimrao Ambedkar University (A Central University), Vidya-Vihar, Rae Bareli Road, Lucknow (U.P.), India. The analysis of variance clearly reveals significant differences among the genotypes for all characters. The observations recorded on various characters showed that the estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient variation (GCV) for all characters. The high phenotypic as well as genotypic coefficient of variation were observed in marketable fruit yield per plant (39.36%) followed by average fruit weight (29.73%) and number of branches per plant (27.18%). High estimates of heritability were recorded for different characters viz., average fruit weight (98.6%) followed by total soluble solids (97.8%), total sugars (97.7%) and days to anthesis of first pistillate flowers (97.2%). The parameters which observed were found to be very high estimate value of genetic advance in per cent of mean of (60.14%) average fruit weight (60.14%) followed by titratable acidity (53.73%), number of branches per plant (53.47%), total soluble solids (52.81%) and marketable fruit yield per plant (47.87%).

Published: October 2021

Postpartum haemorrhage (PPH) has been more common over the last three decades, accounting for 11% of all pregnancy-related deaths in the United States. In the third stage of labour, risk classification and active management are crucial preventative techniques. To avoid negative effects, a multidisciplinary approach to PPH patient care is required. To treat uterine atony, uterotonic medicines like oxytocin are used in combination with manipulative procedures like uterine massage and balloon tamponade. The amount of blood loss, duration of the third stage, need for MRP, incidence of PPH, need for repeated oxytocics, and its side effects were measured in Group I 100 women who were administered injection oxytocin 10 IU injection methergin 0.2 mg IV within one minute of the baby's delivery. The mean blood loss at vaginal delivery in Group I was 100-150 ml and in group I P value 0.027, which was statistically significant .In  Group II was 160-200 ml with P value 0.036, which was statistically significant. The mean duration of third stag labour in Group 1 was 124.6 min and Group 2 was 144.8 min intravenous methergin is a better uterotonic when compared to intramuscular oxytocin to reduce the amount of blood loss at delivery and prevent complications like atonic PPH.

Scleroderma renal crisis is a life-threatening condition. It usually starts with a sudden onset of severe hypertension, followed by renal failure, hypertensive encephalopathy, congestive heart failure, and/or microangiopathic hemolytic anemia. Renal ischemia, hyperplasia of the juxtaglomerular apparatus, activation of the renin-angiotensin-aldosterone system (RAAS), and an increase in blood pressure are caused by decreased blood flow caused by structural changes in the blood vessels as well as renal vasospasm ("Raynaud's phenomenon"). This overview discusses the evaluation, diagnosis, and treatment of scleroderma renal crisis, emphasizing the importance of early detection of disease, strong correlation of corticosteroids intake and the disease incidence, and best approach of such cases.

Published: October 2021

Although pharmaceuticals have made a main influence to health, a large proportion of the world’s population today are facing problems when consuming and accessing medicines. Healthcare professionals are usually sharing their health decisions with their patients in terms of the availability of medicines and its accessibility. Accordingly, patients are being more involved in taking actions either with or without direct healthcare professional guidance, seeking for other facilities to obtain medicines or tend to self-care. Self medication is becoming common in our routine life. This is actually an unhealthy and risky practices. Present study was done to determine the survey on self medication among the general population. A cross sectional study was conducted among the general population of pondicherry.111 persons took part in this cross sectional study. Data is analysed using suitable statistical methods. Among 111 persons    participated in the study the most common reason to take self medication is in case of minor illness and the sources of information about the drug is from the previous prescription and the drugs they get from medical shop. Only 28.4 % visits the qualified medical practioner in case of illness and mostly they have taken medicines for cough, cold, sore throat and followed by that they have taken medications for headache. Out of 111 persons most of them have taken is analgesics followed by allergy medications. The general population has taken the self medication which is a wrong practice.

Background: The users of mobile phones often contaminate them with several microflorae including viruses, fungi, and bacteria via unhygienic conditions and habits making phones a breeding ground and a tool for the transmission of infections. This study examined microbial contamination of mobile phones of health care workers (HCWs) and the risk of nosocomial infections at the Mampong Municipal Government Hospital (MMGH), Ghana.

Methods: We employed a cross-sectional study design to characterize bacterial microflora on mobile phones of HCWs at the MMGH. A random sample of thirty-five [1] mobile phones of HCWs was swabbed for microbiological analysis from the Dental, Children, Male, Theatre and Laboratory departments. A 0.1 ml sterile buffered peptone water was used to make a uniform suspension of each sample and streaked on blood agar and MacConkey agar and incubated at 37℃ for 48 hours. Bacteria were isolated and identified using suitable laboratory and biochemical methods. Analysis of data was done using SPSS-IBM version 16.

Results: All cell phones were contaminated with one or more species of bacteria. Cell phones from Male, Dental and Laboratory departments had 85.7%, 71.4% and 57.1% prevalence of bacterial contamination respectively while Children’s and Theatre departments each recorded 28.6%. Bacterial contaminants identified were Staphylococcus epidermidis (G+) (37%), Staphylococcus aureus (G+) (26%), E. coli (G-) (20%), Bacillus spp. (G+) (11%) and Klebsiella spp. (G-) (6%.).  Apart from the Children’s Ward, E. coli was isolated at all study sites and the most prevalent (42.9%) at the Dental Unit. Klebsiella spp (G-) (28.6%) was isolated only at the Children’s ward.

Conclusion: Mobile phones of HCWs harboured possible pathogens that could cause nosocomial infections among patients. Therefore, strict handwashing practices should be adhered to by HCWs before and after phone use before contact with the patient to reduce the risk of nosocomial infections. This has become even more relevant in the wake of Covid-19 pandemic.

This research analyses the characteristics of travel time reliability for the road network in Kota Bandar Lampung. Therefore, travel time consists of access, wait and interchange time, while its reliability deals with variations of in-passenger/private cars time. Survey of travel time on each road was carried out for 12 hours (from 06.00 to 18.00) for five working days. Furthermore, the buffer time method was used to measure the characteristics of time travel reliability consisting of five measuring tools, namely planning time, planning time index, buffer time, buffer time index and travel time index. This research found that the temporal effects are the main factor that tends to affect travel time, whereas network effects are the second factor that tends to affect travel time. Furthermore, the regression equation was developed to express the effect of planning time (TPlan) and free-flow travel time on average travel time .

Fly ash has been highly advocated to be re-utilized as a construction material. The most common utilization is to partially replace cement in a low-percentage scheme. However, there are several other schemes available to potentially use fly ash as binder in concrete that have not been widely exercised, especially those utilizing it in high to very high volume. In those schemes, high-volume fly ash (HVFA) concrete might use more than 50% fly ash to replace cement. To exploit its self-cementing properties, with or without the addition of other compounds, such as calcium hydroxide, fly ash might be used in very high percentage of cement replacement. In geopolymeric system, fly ash acts as the precursor of a stable binder, with the presence of highly alkaline solution. This paper demonstrates a model to investigate the potential of fly ash in several binder systems. The results show that fly ash from a good source can be utilized as an alternative binder in several different schemes.
