Published: January 2019

El sexo, el género, las sexualidades y las sexualidades periféricas con sus diversas expresiones y más variadas expresiones, se han convertido hoy, en temas que suscitan diversos grados de controversia y polémica, especialmente para los investigadores de la conducta humana. La falta de un lenguaje eminentemente “sexológico” ha ocasionado confusiones y desconocimiento sobre el uso y aplicación de la terminología correcta. En este trabajo se destacará la pluralidad de los significados desde una terminología sexológica actual.
No se trata de un trabajo qué pretenda resolver todas las diferencias del uso y del significado de la terminología sexológica, sin embargo, la clarificación de los términos adquiere relevancia, ante todo, por la imperiosa necesidad de una comunicación efectiva y asertiva entre las diferentes disciplinas del quehacer humano involucradas y que dado que el lenguaje representa el pensamiento, no es posible esperar claridad conceptual si existe una imprecisión lingüística, tampoco se puede polemizar la terminología sin considerar los conceptos que las palabras se suponen representan por si mismas; de aquí surge la razón de inexactitudes cuando se trata de referirse a puntos específicos de la sexualidad humana.

Published: January 2019

A 29-year-old 11-week pregnant multigravida woman without previous medical history presentedwith sudden onset of hematemesis. This case illustrates the occurrence of a rare complication (rupture of pseudoaneurysm of right hepatic artery inside the biliary system), appearing as upper gastrointestinal bleeding in a pregnant woman. The cause of the rupture is presumably pregnancy-related. We would like to emphasize the presence of pseudoaneurysm of the hepatic artery as a rare cause of gastrointestinal bleeding in pregnancy.

Figure 1 and 2 CTA showed a lobulated contour of saccular aneurysmal dilatation at proximal right hepatic artery, measured about 3.5x3.2x1.6 cm in size and 2.6 mm in neck width; pseudoaneurysm is likely. There is perianeurysmal heterogeneously hyperdense non-enhancing lesion which shows flip-flop phenomenon, measured about 5.5x6.1x5.5 cm in size; Partially thrombosed pseudoaneurysm at proximal right hepatic artery is likely. This lesion causes stretching of the common hepatic artery and portal vein. Hyperdenselesion with flip-flop phenomenon is also seen within dilated bilateral IHD, CHD, CBD and gallbladder; Contrast extravasation into CHD, CBD, 1st, 2nd, 3rd, 4th part of duodenum and jejunum is detected in portovenous phase. hemobilia is suggested.

Genetic Relatedness among Escherichia coli Isolated from Clinical Samples
Authors: Ahsan Sunjukta , Amin Ruhul , Bhowmik Anindita 
Published: January 2019

A common member of the intestinal microbiota in humans and animals is Escherichia coli. Based on the presence of virulence factors, E. coli can be potentially pathogenic. The focus of this study was to determine genotypic diversity among clinical strains of E. coli. Test isolates were identified by biochemical, culture-based and molecular tests. Partial sequence of 16s rDNA was determined by Polymerase Chain Reaction using universal primers. The sequences were used as input in Basic Local Alignment Search Tool (BLAST) to reconfirm the identity of the isolates. Sequences were edited in Chromas and aligned in Bioedit. Afterwards, sequences were fed into Mega 5 and a dendogram was constructed. We used three sequences deposited in GenBank for comparison with our test sequences. It was found that two of our sequences showed similarity to the reference sequences. One of the isolates was similar to a Uropathogenic and a commensal E. coli. The other isolate showed similarity to a UPEC strain. It is possible that both of these isolates were commensal bacteria that led to opportunistic infection in the patients. The rest of the nine strains were different from the reference sequences. These isolates may be opportunistic pathogens that have undergone mutation events leading to sufficiently different rDNA sequences from the reference bacteria. Or they may also be pathogenic strains that caused infection in patients. This study indicated that clinical isolates of E. coli show variation in terms of their rDNA sequences. In order to study their phylogeny, other supporting tools such as investigation for phylogenetic markers, RAPD, ARDRA, ERIC-PCR, ribotyping, etc. may be used to study variation among isolates to a more significant extent.

Waarom het onderzoek naar veiligheidsbeleving een nieuwe impuls nodig heeft

The need for a new impulse in fear of crime studies
The security landscape has changed rapidly. New or revived threats have emerged, such as terrorism and cybercrime, bringing new or revived fears and anxieties as well. Actors in security policy feel a need to address these fears, but do not know how. Can the criminological subdiscipline of fear of crime studies provide the knowledge and understanding that is needed? A quick scan of the state of the art in this research domain, gives two reasons why it cannot: (1) fear of crime studies have yielded much knowledge on operationalization, measurement and determinants of fear of crime, but far less in mechanisms, trends, effects and influenceability, whereas insight in the latter issues is what is mostly needed in security policy; and (2) fear of crime studies are still mainly focused on the ‘traditional’ fear of crime, while fear of new crimes and threats remains under-researched. A shift of focus in fear of crime studies is urgently needed.

In search of the roots of fear of crime. No neighborhood is the same
The aim of this article is to search for a more focused approach of fighting back against ‘the fear of crime’. It is based on a study of the backgrounds of risen levels of fear of crime in twelve neighborhoods in the regions of Utrecht and Rotterdam, the Netherlands. Eight central themes could be identified in the stories of 240 respondents: specific locations, avoidance behavior, social stability, social quality, superdiversity, negative neighborhood images, burglary, and societal pessimism. Despite the fact that these central themes appeared in the overall analysis, every neighborhood showed another mix of factors explaining risen levels of fear of crime. This means that policies to reduce ‘the fear of crime’ should focus on specific, local explanations and should always be tailor-made.
Etnische diversiteit en onveiligheidsgevoelens in de buurt

Ethnic diversity and fear of crime in the neighborhood
Living in a multicultural environment may be accompanied with an increased fear of crime. Residents may become alienated in a very diverse environment and withdraw themselves in their own social world. This ‘hunkering down’ may ensue feelings of unsafety. However, social scientists have done hardly any research on whether citizens who live in a multicultural environment in Western Europe actually feel more unsafe. This study seeks to contribute to fill in this knowledge gap. The authors’ research reveals that residents are more likely to feel unsafe in neighborhoods with a high degree of ethnic diversity. The aforementioned correlation is the most noticeable in neighborhoods consisting of people on medium incomes.

Authors: Willighagen Lars G 
Published: January 2019

Background. Given the vast number of standards and formats for bibliographical data, any program working with bibliographies and citations has to be able to interpret such data. This paper describes the development of Citation.js (https://citation.js.org/), a tool to parse and format according to those standards. The program follows modern guidelines for software in general and JavaScript in specific, such as version control, source code analysis, integration testing and semantic versioning.
Results. The result is an extensible tool that has already seen adaption in a variety of sources and use cases: as part of a server-side page generator of a publishing platform, as part of a local extensible document generator, and as part of an in-browser converter of extracted references. Use cases range from transforming a list of Wikidata identifiers into a BibTeX file on the command line, to displaying RIS references on a webpage with added Altmetric badges to generating "How to cite this" sections on a blog.
Conclusions. Citation.js is a library supporting various formats of bibliographic information in a broad selection of use cases and environments. Given the support for plugins, more formats can be added with relative ease.

Nurse Anesthetists play an important role in this process, and have been given new tasks as a result of PICC-line implementation. This study aimed to describe Nurse Anesthetists’ experiences with implementation of PICC-line in hospital. A qualitative design, the data are based on three focus groups interviews with fifteen nurse anesthetists. The interviews were analyzed using a hermeneutic approach. Being a PICC-line nurse led to a feeling of competence, independence, motivation and meaningfulness. The implementation required good structure and organization, as well as enthusiasm. Collaboration and support influenced the implementation process. Good organization and enough available personnel, as well as good collaboration and support from the Anesthesiologists and the management are essential for a successful implementation.

AbstractThe strategy of partial Pb2+ substitution is applied, in prototypical MAPbI3 perovskite, with a large array of metal cations in order to comprehensively explore their possible incorporation in the perovskite lattice at Pb2+ sites and thus obtain improved photostability of the absorber. An analysis of lattice parameters and optoelectronic properties of MAPb1‐xMxI∼3 compositions allowed authors to deduce which metal cations are partially incorporated in the perovskite structure and which are expelled in the form of secondary phases. Curious effects of metal incorporation are observed, such as a decrease in the tetragonal distortion ratio and a change in the band gap. This work reveals that the doping of 11 metal cations significantly improves the photostability of the MAPbI3 films. Multiple MAPb1‐xMxI∼3 formulations deliver superior power conversion efficiencies (PCEs) in solar cells. The DFT calculations further demonstrate a complex relationship between the synthetic conditions and doping patterns. The performed study is thus a stepping stone in the development of more stable perovskite absorbers with superior photovoltaic properties.
Enhancing Durability of Organic–Inorganic Hybrid Perovskite Solar Cells in High‐Temperature Environments: Exploring Thermal Stability, Molecular Structures, and AI Applications
Authors: Su Shimiao , Ahn Taekyu , Yang Yun 
Published: November 2024

AbstractThe commercialization of perovskite solar cells (PSCs), as an emerging industry, still faces competition from other renewable energy technologies in the market. It is essential to ensure that PSCs are durable and stable in high‐temperature environments in order to meet the varied market demands of hot regions or seasons. The influence of high temperatures on the PSCs is complex, encompassing factors such as lattice strain, crystal phase changes, the creation of defects, and ion movement. Furthermore, it intensifies lattice vibrations and phonon scattering, which in turn impacts the migration rate of charge carriers. This review focuses on the durability of organic–inorganic hybrid PSCs under high temperatures. It begins by analyzing the impact of external temperature variations on the internal energy dynamics of PSCs. Subsequently, it outlines the various mechanisms provided by different functional molecules, applied to interface stabilization, grain boundary passivation, crystal growth control, electrode protection, and the development of new hole transport layers, to enhance the thermal stability of PSCs. Additionally, machine learning (ML) is discussed for predicting crystal structure stability, PSCs operational stability, and material screening, with a focus on the potential of deep learning and explainable artifical intelligence (AI) techniques in the commercialization of PSCs.

AbstractPathogenic bacteria are commonly found in food, water, and soil, posing significant public health challenges globally. Therefore, early, rapid, and highly sensitive strategies for monitoring the bacterial proliferation are crucial for ensuring public health, medical diagnosis, and food safety. Compared to traditional techniques, microfluidic platforms provide powerful detective tools characterized by high integration, high throughput, ease of operation, low reagent consumption, and high sensitivity. Driven by substantial commercial demand, research and development in microfluidic‐based rapid detection methods and technologies has progressed significantly derived by the interdisciplinary integration of multiple disciplines. In this review, progress in clinical detection of pathogenic bacteria with microfluidic biosensors, including microfluidic devices for point‐of‐care (POC) testing, is summarized. Strategies for pathogenic bacteria detection, containing their advantages and disadvantages are discussed in detail. Advanced platforms for capturing and detecting pathogenic bacteria, such as microchannels, microarrays, digital microfluidics (DMF) and paper‐based platforms, are highlighted. The accomplishments and shortcomings of these microfluidic devices are also summarized. Additionally, case studies of biosensor‑based microfluidic devices used for detecting diseases caused by bacterial imbalances are listed. Finally, possible research perspectives for further development in highly effective biosensor‑based microfluidics for clinical detection of pathogenic bacteria are proposed.
