Abstract

Objectives
Uterine rupture in pregnancy is an obstetric emergency especially in developing countries associated with a significant increase in maternal plus perinatal mortality and morbidity. There is a need to identify the prevalence together with underlining factors which could guide effective intervention. Hence, the study aimed at determining the prevalence of uterine rupture, predisposing factors, management options plus clinical presentation at Secondary Health Facility in Okitipupa, South West Nigeria.

Methods
This was a retrospective study of patients with a uterine rupture from January 2009 to December 2012 in the Department of Obstetrics and Gynaecology State Specialist Hospital Okitipupa. The case records of patients in this period were retrieved from the medical health records department and relevant data of sociodemographic characteristics, clinical presentation, management as well as maternal and perinatal outcome were collated using a structured questionnaire. Data were analyzed using Microsoft Excel version 10.

Results
Of the 11,377 deliveries during the study period a total of 52 uterine ruptures were recorded during the same period making an incidence of 0.46% or a ratio of 1:219 deliveries. Most of the patients 28 (60.9%) were 20–30 years of age. Uterine rupture was more common amongst multiparous women 36 (78.3%). None was a primigravida. The majority of the patients 34 (73.9%) were nonattendants at the antenatal clinic. The commonest single predisposing factor was the presence of a previous scar being present in 12 (26.1%) of the patients. The most common surgery performed for uterine rupture in the series was repair only 24 (52.2%). There is an absence of uterine rupture in primigravida supports the belief that primigravida is somehow immune to rupture.

Conclusions
Rupture of the gravid uterus is a major contributor to maternal and perinatal mortality in Okitipupa Southwest Nigeria.
„Verbalaspekt“ und Textfunktion bei Otfrid
Authors: Fleißner Fabian 
Published: June 2021

Abstract
Althochdeutsche Verbalkomposita mit dem Präfix gi- und zugehörige Simplexverben werden traditionell mit der grammatischen Kategorie des Aspekts in Zusammenhang gebracht, woraus sich einige textpragmatische Konsequenzen zumindest theoretisch ableiten lassen. Dieser Beitrag soll zeigen, dass weder eine solche Funktionszuweisung noch die Annahme textueller Distributionsmuster geeignet sind, um den Gegensatz von Simplex und Kompositum adäquat zu beschreiben. Stattdessen wird eine funktionale Opposition angenommen, wobei die Präfigierung Ausdruck der Perspektive ist, die der Sprecher gegenüber einem wahrnehmbaren Effekt der Verbalhandlung einnimmt.1

Jahrhunderts anhand ausgewählter Texte von Houston Stewart Chamberlain, Oswald Spengler und Thomas Mann diskurslexikographisch analysiert werden. Dabei wird die Frage im Vordergrund stehen, wie die jeweils spezifische Autor- bzw. Textsemantik in eine diskurssemantische Beschreibung überführt werden kann.
Continuum Modeling Perspectives of Non-Fourier Heat Conduction in Biological Systems
Authors: Sudár Ákos , Futaki Gergely , Kovács Róbert 
Published: June 2021

Abstract
The thermal modeling of biological systems is increasingly important in the development of more advanced and more precise techniques such as ultrasound surgery. One of the primary barriers is the complexity of biological materials: the geometrical, structural, and material properties vary in a wide range. In the present paper, we focus on the continuum modeling of heterogeneous materials of biological origin. There are numerous examples in the literature for non-Fourier thermal models. However, as we realized, they are associated with a few common misconceptions. Therefore, we first aim to clarify the basic concepts of non-Fourier thermal models. These concepts are demonstrated by revisiting two experiments from the literature in which the Cattaneo–Vernotte and the dual phase lag models are utilized. Our investigation revealed that these non-Fourier models are based on misinterpretations of the measured data, and the seeming deviation from Fourier’s law originates from the source terms and boundary conditions.
Long-standing taxonomic confusion over the identity of Hypudaeus syriacus Brants, 1827, at last resolved
Authors: Kryštufek Boris , Shenbrot Gregory , Janžekovič Franc 
Published: June 2021

Abstract
In this study we address the taxonomic identity of Hypudaeus syriacus, an arvicoline (Arvicolinae) from the Middle East which was described and named by Anton Brants in 1827. Although the type specimen is preserved, an exact conclusion regarding its identity was not achieved until recently. Currently, syriacus is reported as a synonym of Microtus socialis. Our analysis of the M1 occlusal pattern has convincingly demonstrated that the type clusters with the European snow vole Chionomys nivalis and does not match any species of Microtus from the Middle East. H. syriacus predates Arvicola nivalis Martins, 1842, which is in use for the European snow vole and is therefore the oldest available name for the species. Under the provision specified by Article 23.9.1 of the International Code of Zoological Nomenclature, syriacus is not a forgotten name (nomen oblitum) because several authors writing after 1899 used it as a valid name. Referring to the principle of priority, as stipulated in the Code, the valid name combination for the European snow vole is Chionomys syriacus (Brants, A. (1827). Het geslacht der muizen door Linneaus opgesteld, volgens de tegenswoordige toestand der wettenschap in familien, geslachten en soorten. Akademische Boekdrukkery, Berlyn [Berlin]). We restrict the type locality for syriacus to Mount Sanine in the Mount Lebanon range, northern Lebanon.

Abstract
Grid implementation is a principal unit in electrical and electronic engineering but it depends on the domain of these projects. For example, depending on the grid and the signal processing in that fields of electronic and electrical engineering, such as more abstract mathematics in signal conversion and e-transmission theory griding, etc. Provides transmission through grid nodes. Graph theory is very useful in research fields. As topological indices, there are more actual numbers associated with chemical composition complaints connected to the chemical grid with physical and chemical properties and reactions. In this paper, we expand the work to interconnected grid and examine the first Zagreb, the second Zagreb, Randic, sum-connectivity, harmonic, geometric, and atom bond connectivity exponents of hierarchical hypercube network based on vertex-edge and edge-vertex degree.
Chemical similarity methods for analyzing secondary metabolite structures
Authors: Ekaney Lena Y. E. , Eni Donatus B. , Ntie-Kang Fidele 
Published: June 2021

Abstract
The relation that exists between the structure of a compound and its function is an integral part of chemoinformatics. The similarity principle states that “structurally similar molecules tend to have similar properties and similar molecules exert similar biological activities”. The similarity of the molecules can either be studied at the structure level or at the descriptor level (properties level). Generally, the objective of chemical similarity measures is to enhance prediction of the biological activities of molecules. In this article, an overview of various methods used to compare the similarity between metabolite structures has been provided, including two-dimensional (2D) and three-dimensional (3D) approaches. The focus has been on methods description; e.g. fingerprint-based similarity in which the molecules under study are first fragmented and their fingerprints are computed, 2D structural similarity by comparing the Tanimoto coefficients and Euclidean distances, as well as the use of physiochemical properties descriptor-based similarity methods. The similarity between molecules could also be measured by using data mining (clustering) techniques, e.g. by using virtual screening (VS)-based similarity methods. In this approach, the molecules with the desired descriptors or /and structures are screened from large databases. Lastly, SMILES-based chemical similarity search is an important method for studying the exact structure search, substructure search and also descriptor similarity. The use of a particular method depends upon the requirements of the researcher.

Abstract
The contamination of water sources as a result of man’s activities is of concern because of its potential impact on the health of humans. Samples of groundwater were collected from four households within metropolitan Lagos between the months of April and August, 2019. The samples were analyzed for cadmium, calcium, iron, lead, manganese and zinc using atomic absorption spectrometry. Structured questionnaire was administered to the residents in households where the water samples were collected. Results obtained were compared with global background values and WHO guidelines for drinking water. The pH values ranged from 5.16 ± 0.26 to 5.29 ± 0.44, whereas, the control pH values were within the WHO guidelines of 6.5–8.5. The concentrations (mg/L) ranged from 2.04 ± 1.01–23.48 ± 8.81 (calcium); 3.35 ± 1.94–3.60 ± 2.25 (iron); 0.31 ± 0.42–0.47 ± 0.51 (manganese) and 0.27 ± 0.04–0.77 ± 0.69 (zinc), respectively. Cadmium and lead were not detected. The health risk indices (HRI) values were found to be in the order of Fe > Zn > Mn and were below the threshold value of 1. Statistical analysis of variance (ANOVA) was used to ascertain statistical significant differences of metal concentrations in the four locations. Metal pollution source control and periodic water quality monitoring is recommended.

Abstract
A comparison was carried out between quadrupole inductively coupled plasma mass spectrometry (ICP-QMS) detection and sector field ICP-MS (ICP-SFMS) detection for quantification of elements such as arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn), and uranium (U) in drinking water. A drinking water sample obtained from the International Atomic Energy Agency was used for validation measurement methods. ICP-QMS and ICP-SFMS obtained recoveries of 95–107% and 95–105%, respectively. Moreover, the relative standard deviation for ICP-QMS was <5% in comparison with ICP-SFMS, which was <2%. The limits of detection obtained in ICP-MS and ICP-SFMS for each element were under ng L−1, except for Zn. Both methods were applied to evaluate these elements in drinking water for consumption in Mexico. According to Mexican Regulation for Human Drinking Water NOM-201-SSA1-2015 and Environmental Protection Agency (EPA) from the United States, the values are within the allowable limits. In conclusion, ICP-QMS and ICP-SFMS are excellent choices for measurements of these toxic elements in water samples because of high precision and accuracy in routine analysis minutes, while also exhibiting excellent precision and accuracy in routine analysis.

Abstract
Shrimps, including Pestarella tyrrhena
, are highly susceptible to deterioration whereas odour production has been indicated as one of the factors determining the perishability and bait potential of shrimps. In this study, volatile components generated from fresh egg, adult female and male of P. tyrrhena were assessed using two-dimensional gas chromatography coupled to time-of-flight mass spectrometry to understand their contribution to odour production. Alkenes, alkynes, alcohols, aldehydes, a ketone, acids, esters, an amine, sulphur-containing and miscellaneous compounds were detected. Meanwhile, adult females and males of P. tyrrhena had a higher number of these volatile compounds. The detection of 2-methyl propan-1-ol with pungent odour only in the male sample of P. tyrhenna suggests that the male of this shrimp species may not completely attract fishes to hooks. Overall, the study established shrimp developmental stage and sex as additional factors influencing the production of volatile compounds, flavour/aroma/odour and fishing bait attributes of P. tyrrhena. Detection of N-nitrosodimethylamine (a carcinogen) in the shrimp samples, particularly the adult male, calls for caution in their direct human consumption and use as fishing bait.

Published: June 2021

ZusammenfassungIn diesem Artikel stellen wir die Ergebnisse einer ersten systematischen Erhebung des Frauenanteils in der Volkswirtschaftslehre an deutschen Universitäten auf allen Karriereebenen dar. Unsere Zahlen verdeutlichen, dass Frauen auf allen Stufen unterrepräsentiert sind. Dabei fällt der Frauenanteil von der Assistenzprofessur zur „vollen“ Professur stark ab: Nur 15 Prozent der volkswirtschaftlichen Lehrstühle werden von Frauen besetzt. In Österreich und der Schweiz ist der Frauenanteil unter den Professuren ähnlich niedrig, in den meisten anderen europäischen Ländern jedoch höher. Der Frauenanteil variiert erheblich zwischen den Forschungsfeldern und ist besonders gering in den Bereichen Makroökonomie und Finanzen. Wir weisen auf potentielle Ursachen, Konsequenzen und Maßnahmen hin, um dem Problem der geringen Repräsentation von Frauen in unserer Profession entgegenzuwirken.
Scoping review of the risk factors and time frame for development of post-traumatic hydrocephalus

Published: June 2021

Abstract
Post-traumatic hydrocephalus (PTH) following traumatic brain injury (TBI) may develop within or beyond the acute phase of recovery. Recognition and subsequent treatment of this condition leads to improved neurologic outcomes. In this scoping review, we identify statistically significant demographic, clinical, radiographic, and surgical risk factors as well as a predictive time frame for the onset of PTH in order to facilitate timely diagnosis. Two researchers independently performed a scoping review of the PubMed and Cochrane databases for articles relevant to risk factors for PTH. Articles that met inclusion and exclusion criteria underwent qualitative analysis. Twenty-seven articles were reviewed for statistically significant risk factors and a proposed time frame for the onset of PTH. Variables that could serve as proxies for severe brain injuries were identified as risk factors. The most commonly identified risk factors included either very young or old age, intracranial hemorrhage including intraventricular hemorrhage, hygroma, and need for decompressive craniectomy. Although the timeframe for diagnosis of PTH varied widely from within one week to 31.5 months after injury, the first 50 days were more likely. Established risk factors and timeframe for PTH development may assist clinicians in the early diagnosis of PTH after TBI. Increased consistency in diagnostic criterion and reporting of PTH may improve recognition with early treatment of this condition in order to improve outcomes.
Francesco Salviati’s Lamentation for Venice and the Origins of the Disegno/Colorito Debate
Authors: Biffis Mattia 
Published: June 2021

Abstract
The Lamentation over the Dead Christ is unquestionably one of the most important works that Francesco Salviati produced during the roughly 18 months that he spent in Venice between 1539 and 1540. Yet, despite its importance, scholars have seldom discussed in any detail the work and its significance to Salviati’s famous sojourn in northern Italy. Recognizing Francesco’s physical presence in the work, this essay reconsiders this painting as an emphatic statement on the local school of painting. This provocative visual statement is related to the artist’s experience in the city, serving as a gauge of his negative attitude to the local environment, which is confirmed by his own remark that living in Venice “was not for men of drawing.” The Lamentation appears therefore as an early critical contribution in the form of an altarpiece to the long-standing debate over disegno and colorito.
Ethics: use and misuse of assisted reproductive techniques across species
Authors: Campbell Madeleine L H 
Published: June 2021

The boundaries of what we are able to do using ARTs are fast-moving. In both human and veterinary medicine, this presents a fundamental question: ‘Just because we can, should we?’ or, to rephrase the same question: ‘How can we distinguish between what is a use and a misuse of an ART, across species?’ This paper assesses the scientific evidence base for and against the use of ARTs and offers a personal opinion on how we can use such evidence to inform an ethical distinction between justifiable and unjustifiable uses of the techniques. It is argued that the law provides a necessary but insufficient basis for such distinctions. Based on the evidence about harms and benefits, ARTs may be classified into three groups: those which should be rarely used; those for which current evidence supports arguments both for and against their use and those which there is an ethical imperative to use. To which category a particular ART falls into varies depending upon the species to which it is being applied and the reason we are using it. In order to ensure that our ethical oversight keeps up with our technical prowess, the medical and veterinary professions should keep discussing and debating the moral basis of the use of ARTs, not only with each other but also with the lay public.

Lay summary
The use of assisted reproductive techniques (ARTs) has become commonplace in both human and veterinary medicine. Technical limitations are rapidly advancing. This raises a fundamental issue: ‘How can we distinguish between what is a use and a misuse of an ART, across species?’. ‘Misuse’ may be defined both in terms of physical and psychological harms and of moral disquiet about ‘interfering with nature’. This paper assesses the scientific evidence base for and against the use of ARTs and provides a personal opinion on how we can use such evidence to inform an ethical distinction between justifiable and unjustifiable uses of the techniques. We need to consider not only legal but also non-legal ethical justifications for their use. Based on the evidence about harms and benefits, ARTs may be classified into three groups: those which should be rarely used; those for which current evidence supports arguments both for and against their use and those for which there is an ethical imperative to use. To which category a particular ART falls into varies depending upon the species to which it is being applied and the reason we are using it. Open discussion between the medical and veterinary professions and the public is necessary to ensure that ethical oversight of the use of ARTs across species keeps up with technical developments.
NOVAS PERSPECTIVAS DA RELIGIOSIDADE POPULAR
Authors: Quadros Eduardo Gusmão de , Filho Robson Rodrigues Gomes 
Published: June 2021

Normalmente encarado a partir de um olhar versado sobre a comparação das práticas religiosas populares com os modelos oficiais do que uma dada instituição religiosa pretende em seus cânones, a religiosidade popular foi ao longo do século 19 definida por tudo aquilo que “manifestasse o supersticioso, o grosseiro, o curioso e o vulgar.” (CÉSAR, 1976) Ainda no século XX, todavia, não é raro encontrarmos interpretações acadêmicas que desqualificam a religiosidade popular com atributos como “crendice do povo”, “paranoia”, “obsessão generalizada”, “comportamento sacrílego”, “religiosidade acrítica e emocional”, “engodo” e “primarismo acrítico”.
Por um lado, muitas dessas adjetivações advêm das oposições rígidas entre sagrado/profano, magia/religião, fé/superstição que ainda permeiam os referenciais teóricos acadêmicos. Elas têm se mostrado bastante limitadas quando o pesquisador se empenha em analisar o cotidiano da religiosidade popular. Por outro, as novas relações e novos movimentos religiosos presentes no mundo contemporâneo induz os pesquisadores do assunto desafios cada vez maiores para se pensar a amplitude do conceito de religião e/ou religiosidade popular em suas infinitesimais dinâmicas.
Em face disso, o presente dossiê propõe-se a reunir contribuições acadêmicas das mais diversas matizes quereflitam acerca da religião e religiosidade popular, de modo a se pensar de como as novas e tradicionais perspectivas do estudos da religião têm contribuído para abrir novas formas de leitura da religiosidade e religião popular na América Latina.
CULTURAS NAS ORGANIZAÇÕES: HOMOGENEIDADES E HETEROGENEIDADES NA ADMINISTRAÇÃO DE UMA UNIVERSIDADE PÚBLICA
Authors: Corrêa Marcos Paulo De Oliveira , Da Cruz Marcus Vinicius Gonçalves 
Published: June 2021

<div id="icpbravoaccess_loaded"> <p class="EDCorpodeTexto">As significações culturais formam padrões de referência, de validação e de legitimação das ações de um determinado grupo social, constituindo, nesse sentido, panoramas possíveis de apreender e revelar conjunturas existentes em uma organização. Este trabalho se utiliza da abordagem das “três perspectivas”, proposta por Martin (1992), a saber: “integração”, “diferenciação” e “fragmentação”. O pressuposto que este estudo pretende fortalecer é a de que, a partir da análise de um contexto social, são possíveis a ampliação e o aprofundamento do trato de indagações plurais das culturas nos ambientes organizacionais. Esta pesquisa tomou como foco as manifestações culturais expressadas por servidores públicos que atuam em diferentes departamentos que compõem um órgão administrativo de uma universidade federal de ensino superior. As entrevistas semiestruturadas, a pesquisa documental e a análise de conteúdo foram os principais instrumentos utilizados para a identificação das manifestações culturais presentes no contexto organizacional analisado. Concluiu-se pelo argumento de que as investigações culturais que excluem os conflitos e as ambiguidades podem vir a silenciar fatos organizacionais importantes bem como os insumos provindos de indivíduos que nem sempre possuem poder nesses contextos.</p></div>
