The role of hydrogen gas bubble
in hydrophobic properties in mixed
micro layer (Al2O3+Mg)
Authors: Subagyo R. , Wardana I.N.G. , Widodo A. , Siswanto E.
Published: November 2020

Purpose: To find out more about the role of hydrogen gas bubbles in improving the
hydrophobic nature of a layer, especially in the layers of microparticles Alumina (Al2O3) with
Magnesium (Mg).
Design/methodology/approach: The method used is an experimental method by first
conducting the SEM-Edx test, testing the content of the elements in the waxy layer and
observing the topographic shape on the surface of the taro leaves. Then prepare a mixture
of Alumina micro particles with Magnesium to investigate the hydrophobicity of the taro
leaves. The mixed presentations between Alumina and Magnesium are: (0, 10, 20, 30, 40,
50, 60, 70, 80, 90 and 100%).
Findings: The results of this study found three conditions of the Alumina and Magnesium
mix layer when in contact with a droplet, namely: Hydrophobic conditions occur when the
surface structure of the rough mixed micro layer forms micro crevices, then bubbles of
hydrogen gas fill it to form trapped gases. When droplets come in contact with the surface of
the mixed layer the effect of the gas being trapped is very effective at creating hydrophobic
properties. While the transition conditions occur when more and more hydrogen gas
bubbles along with the increasing percentage of Mg and the opposite occurs in micro
particle fissures. Bubbles fill the micro-gap space fully so that the tops of the micro particles
are covered by bubbles. This causes the droplet surface tension to weaken, so the droplet
contact angle decreases. Furthermore, hydrophilic conditions occur when the micro gap
is getting narrower as the percentage of Mg increases and the formation of hydrogen gas
bubbles increases. The high level of bubble density in the micro gap closes the peaks of
the micro particles, which results in the surface tension of the droplet getting weaker. In this
weak surface tension condition, the hydrogen bubble can break through the droplet surface
tension and change its hydrophobic nature to hydrophilic.
Research limitations/implications: This research is limited to the hydrophobicity
of Alumina and Magnesium materials, mainly to investigate the role of hydrogen gas in
supporting the hydrophobic nature of taro leaves (Colocasia esculenta).
Practical implications: The practical implication in this study is the use of hydrophobic
membranes which are widely applied to filtration.
Originality/value: Discovered the composition of a membrane mixture of Alumina (Al2O3)
and Magnesium (Mg) to create hydrophilic and hydrophobic conditions.
Metaforic language of the Wrocław School of the Future Model
Authors: Remiszewska Zofia
Published: November 2020

In this article I am looking for an answer to the question: What are the meanings and significances of metaphors in the Wrocław School of the Future? I show the use of metaphorical language in the school, where metaphors are treated as a source of knowledge about the surrounding world, as a kind of support for more effective communication and as a stimulator of the imagination. In the Wrocław School of the Future, it is believed that a child does not have to be doomed to education based on stereotypical behaviors. It is also believed that in the process of education there is a need for creative thinking, based on various associations in which the ability to create a mind map, imagination, or so-called imaginative education is used. Such education at the Wrocław School of the Future is supported by metaphors that play a primary role there.

The objective of the study was to understand the criteria used by the nursing team to assess the pain of children hospitalized in a PICU. This is a qualitative study, targeting the Nursing team of a PICU at an inland hospital of the State of São Paulo. Focus groups were held alternating on odd and even days. The data was analyzed using Thematic Analysis proposed by Bardin. The analysis resulted in two categories, the first: "Experiencing the multidimensionality of children's pain: projections and feelings" and the second: "Pediatric pain assessment: care to be improved". Therefore, the interviewees understand the concept of pain in a specific way and do not use standardized criteria for pain assessment, which generates non-systematic assistance in the management of pain in hospitalized children.
Die Lesbarkeit des Rechts
Authors: Augsberg Ino
Published: November 2020

Die Rechtswissenschaft, liest man in jüngerer Zeit, müsse sich, um den Herausforderungen der Moderne gewachsen zu sein, endlich von ihrem klassischen Anspruch als hermeneutische Textwissenschaft abwenden und stattdessen als pragmatische »Entscheidungswissenschaft« neu konzipieren. Quer zu dieser These wird hier ein Modell vorgeschlagen, das als kennzeichnend für das operative Verfahren des modernen Rechtssystems gerade seine Textualität bestimmt. »Text« benennt dabei nicht länger nur eine bestimmte Schriftform, sondern verweist auf eine juridische Praxis, die, statt sich auf von außen vorgegebene Legitimationsmuster zu stützen, sich über die Schaffung interner Anschlussmöglichkeiten selbst plausibilisiert.
Die Ordnung der Berührung
Authors: Lindemann Gesa
Published: November 2020

Was können wir aus der Coronakrise über moderne Gesellschaften lernen?

Gesa Lindemann zeigt auf, dass die Strukturen der modernen Gesellschaften stabil bleiben, sich unsere alltägliche Berührungsordnung dagegen verändert bzw. verändern kann.

Die Leserinnen und Leser erfahren etwas darüber, in welchem Verhältnis Staat, Politik, Recht, Wirtschaft und Wissenschaft zueinanderstehen und wie diese Bereiche mit ihren eigenen Voraussetzungen und Zielen unser unmittelbares Zusammenleben bestimmen. Die mediale Fokussierung auf sinnliche Aspekte der alltäglichen Berührungsordnung macht den Zusammenhang mit diesen allgemeinen gesellschaftlichen Strukturen sichtbar.

In Zeiten von Corona zeigt sich auch, wie die moderne Gesellschaft immer wieder emanzipatorische Hoffnungen nährt, dass z.B. auch tiefverwurzelte rassistische Strukturen verändert werden können. Die Krise scheint das Ethos der Menschenrechte nicht zu beschädigen. Die Ordnung der Gewalt wird thematisiert über Fragen nach sozialer Ungleichheit und Formen struktureller Gewalt, und gerät in der Diskussion über das Machtmonopol des Staates auch ins Licht der öffentlichen Aufmerksamkeit. Davon zeugt nicht zuletzt die Black-Lives-Matter-Bewegung.

Diese Fragen werden im Buch u.a. diskutiert:

Wie ist das Machtmonopol des Staates definiert?

Ändert sich die Ordnung der Gewalt?

Wie verändert sich das Ethos der Menschenrechte bzw. welche Bedeutung haben Grundrechte?

Wie verändert sich unsere Ordnung der Berührung – die Art wie wir uns ansehen, miteinander agieren, uns körperlich berühren?

Welche Rolle spielt die Digitalisierung?

Wie wird soziale Ungleichheit in der Krise sichtbar? (Stichwort Herdenimmunität)

Welche unterschiedlichen Sorgelogiken machen die Arbeit von Staat, Politik, Recht,

Wirtschaft, Bildung, Wissenschaft und Medizin aus?

Welche Rolle kommt der öffentlichen Berichterstattung zu? Und welche Chancen ergeben sich aus der Fokussierung ganz unterschiedlicher gesellschaftlicher Bereiche?

Wann kann man von struktureller Gewalt sprechen? Und wie wird diese in der Krise sichtbar? (Stichwort Black-Lives-Matter)
A History of Censorship in the United States

Censorship is a centuries-old issue for the United States. The importance of intellectual freedom and the freedom of speech is particularly evident in libraries, organizations dedicated to the access and spread of information. Issues regarding censorship and intellectual freedom have even reached the US Supreme Court. The following essay serves as a history of censorship in the United States, particularly in its libraries, and how the same issues of censorship have now transitioned into the digital age.
Meaning in the Use of Freedom: The Free Press Underground, the University of Missouri, and Students for a Democratic Society
Authors: Drew Chris
Published: November 2020

The Free Press Underground was an independent newspaper edited and published by University of Missouri students in the 1960’s. Four students were arrested for distributing a February,1969 edition of the paper. One of those students was ultimately expelled. Her name was Barbara Papish. She and the ACLU took the MU’s Board of Curators to court, and ultimately made it to the Supreme Court in 1973. Papish’s expulsion was ruled unconstitutional. A deeper analysis of the historical context surrounding this incident will reveal the ongoing power struggle and antagonism shared between the University and the student publishers, and draw lessons for contextualizing free speech incidents. This will be shown as necessary for seeing the underlying purpose, intent, and meaning buried beneath the oft over simplified struggle for public opinion surrounding morality and freedom, as exemplified by this incident.

Perpetual peace projects in late medieval period
Authors: Slović Srđan
Published: November 2020

Projects on the establishment of world peace in the late Middle Ages were initially marked by religious views on the world. Christian church was the subject of war and peace and it did not make differences among peoples. It had universal aspirations. This dogmatic comprehension will be abandoned by the appearance of national states where the state becomes subject of war and peace. A division among nations appears and the possibility of their mutual recognition. In that way relations among states are being regulated from the point of view of international relations. His basic principle becomes the one of sovereign equality, this could happen after the termination of religious wars which got its peak by Westphalia peace. Starting from Dubois, Podjebrady, Penn, Duke of Silly, via Hobbes, Grotius end Puffendorf, it will be possible to determine how changes in society political systems and way of production influenced the developments of ideas on perpetual peace. The achievements of these thinkers were revolutionary and were still valid. It is worth mentioning the principles of sovereign equality of states, the presence of realism in international relations and the existence of judicial institutions such as the International Court of Justice.
Personal data protection from the Criminal Law perspective
Authors: Sekulić Miloš , Grujić Gordan
Published: November 2020

The right to privacy is one of the fundamental human rights that serves to realize a man as a social being and protect the private spheres of their life. Even though this right can be looked at in different ways, due to the modern development of information and communication technologies, it is largely related to personal data and their availability to other persons. In that sense, the right to privacy is also protected via personal data protection. The basis for such protections in Serbian law has already been implemented in the Constitution of Serbia, and by adopting a new Personal Data Protection Law, the legislator has shown their determination to intensify and expand that protection. As it relates to criminal justice protection, a separate criminal offence of unauthorized collection of personal data is prescribed in Article 146 of the Criminal Code. The authors of this scientific paper will try to expose the threat to the right to privacy and personal data, and to give a clearer picture of how criminal justice protection of these values is realized in the Serbian law by presenting the elements of the aforementioned crime.

Published: November 2020

Introduction: Burnout is a complex psychoemotional construct defined by three dimensions: emotional exhaustion, depersonalization, and feeling of diminished personal achievement. It occurs in professionals who work in direct contact with other people. Healthcare professions are classified as the most endangered, with employees in psychiatric institutions being at the top of the pyramid of risk for the development of professional burnout. The aim of this study was to assess the prevalence of job burnout among psychiatric nurses, as well as to examine the correlation of sociodemographic factors with burnout syndrome. Methodology: A non-experimental cross-sectional correlation study was conducted on a sample of 70 nurses employed at the Institute of Mental Health in Belgrade. The study instruments were the Maslach Burnout Inventory - Human Services Survey (MBI-HSS), and the sociodemographic data questionnaire specially designed for this research. Results and discussion: The results show that 34.3% of in the ob-served sample show moderate or severe symptoms of burnout in the domain of emotional exhaustion, in 14.3% of them was registered moderate or severe burnout manifestations in the domain of depersonalization, and 68.6% show of study participants showed moderate or high level of burnout in the personal achievement domain. Correlation analysis of respondents' sociodemographic characteristics with burnout manifestations confirms that depersonalization is statistically significantly associated with mar-ital status (p=0.036). In addition, there is a correlation between emotional exhaustion and education level (ch2-9,431; p=0.051), age of respondents (ch2 =17,802; p=0.023) and length of service (ch2=17,213; p=0.028). Conclusion: Considering the individual and social consequences of job burnout, it is important to identify risk groups among nurses employed in psychiatry institutions, in order to preserve and improve mental health, as well as improve the quality of provided health services.

Authors: Miletić Aleksandra , Savić Nikola , Jokić Zoran , Damnjanović Ivana
Published: November 2020

Introduction: Pregnancy is a specific period of a woman's life in which she should pay special attention to her health potential. Certain health risks, such as drug abuse during pregnancy, can have fatal consequences for the outcome of pregnancy and the health of women and newborns. Drugs are classified into several categories according to their risk of harm to the fetus. The classification of the American Food and Drug Administration (FDA) is most often used, which is the purpose of drugs in the categories for pets (A, B, C, D, H). Aim: Examine the information and personal experiences of pregnant women regarding the use of drugs in pregnancy. Methods: The research was conducted in the form of cross-sectional studies. As a research instrument, a questionnaire for pregnant women was constructed, which assesses their level of information about aspects of drug use in pregnancy, as well as personal experiences. The study included a sample of 60 pregnant women, the sample was intentional, the study was conducted at the Jokić Polyclinic, in the period January-June 2020. Participation in the studies was voluntary and anonymous, the research was approved by the competent authorities of the institution. Results: The subjects in the observed sample were pregnant women aged 21 to 35 years. The majority of pregnant women are uninformed about the use of drugs during pregnancy. The most commonly used drugs in pregnancy are antibiotics. A large number of respondents believe that gynecologists and pharmacists should inform pregnant women more on this topic. Descriptive statistics methods were used in the analysis of the results. Conclusion: The results of the research indicate the need for a higher level of education on the safe use of drugs in pregnancy. It is necessary to intensify health education work in cooperation with health institutions of all levels. This need is also felt by pregnant women who feel that they do not know enough about this topic.
An application of directional quantiles to economic data with a multivariate response
Authors: Kalina Jan
Published: November 2020

Quantile regression represents a popular and useful methodology for modeling quantiles of a response variable based on one or more independent variables. Directional quantiles represent an available extension to the linear regression model with a multivariate response. However, we are not aware of any application of directional quantiles to real data in the literature. An illustration of directional quantiles to an economic dataset is presented in this paper, particularly a modeling of a two-dimensional response in the classical Engel's dataset on household consumption from the 19th century. The results reveal the directional quantiles to yield meaningful results. They order individual observations according to their depth, i.e. from the most central to the most outlying. We compare their result with those of a (more standard) outlier detection. On the whole, we perceive directional quantiles as a potentially useful tool for the analysis of data, if accompanied by a thorough analysis by standard tools.
Abuse of Dominance in the Case-law of the Hungarian Competition Authority – a Historical Overview
Authors: Réger Ákos , Horváth András M.
Published: November 2020

This paper provides a historical overview of the case-law and practices applied by the Hungarian Competition Authority (HCA) in abuse of dominance cases. The paper is co-written by practitioners of complementing antitrust fields, which ensures that both legal and economic considerations are explored. The paper identifies the unique characteristics of Hungarian legislation and case-law and critically evaluates them in light of EU competition law and economics principles. We analyse (i) the reasons for the high number of exploitative cases before 2010, (ii) the general principles applied by the HCA in exclusionary cases, (iii) the cost allocation assessments in dominance cases, and (iv) the issue of significant market power of retailers. The general starting point is that, judging by the number of dominance investigations, there is less antitrust enforcement by the HCA in recent years. However, the article concludes that less enforcement does not mean weaker enforcement. In fact, the quality of dominance cases, considering both legal and economic aspects, has increased over time. This tendency has also led to higher legal certainty in Hungary, which is beneficial for market players. Stronger criticism is only formulated against the concept of significant market power of retailers.
Anticompetitive Patent Settlements – Where Are We Ten Years After the European Commission’s Pharmaceutical Inquiry?
Authors: Laszczyk Anna
Published: November 2020

In 2009, the European Commission published a final report on its market inquiry into the pharmaceutical sector. The report revealed the authority’s concerns regarding market practices of pharmaceutical originator companies aimed at delaying the market entry of cheaper generic pharmaceutical products. One of the delaying practices identified by the European Commission were patent settlements between an originator and a generic company including: (i) a value transfer from the originator to a generic company, and (ii) an obligation of a generic company not to enter the market. These patent settlements were called pay-for-delay agreements since the payment was allegedly made in exchange for the non-market entry obligation. The European Commission continued the investigation of patent settlements by its continuous monitoring. It also initiated antitrust proceedings that terminated with huge fines imposed on pharmaceutical companies. The appeals are now pending before the EU courts. Ten years after the publication of the final report on the market inquiry, this article aims to summarise the development of the case law and provide its critical analysis. The article focuses on the analysis of pay-for-delay agreements as infringements of Article 101 TFEU only and does not consider the conclusion of these agreements as an abuse of a dominant position.
Fertilités
Authors: Breviglieri Marc
Published: November 2020

Cet article brosse un tableau de l’univers végétal d’une oasis du Maroc présaharien (région du Souss) en mettant l’accent sur la présence de femmes âgées issues d’un milieu très modeste venant quotidiennement désherber et collecter des plantes spontanées. Ces femmes entretiennent un lien privilégié avec ces dernières et transmettent leurs pouvoirs nourriciers, prophylactiques, thérapeutiques ou magiques à la communauté oasienne dans son ensemble. Mais une question se pose : que va-t-il advenir de ce champ de relations intégrées aux cycles de fertilité au fil des transformations structurelles et des projets de modernisation que connaissent actuellement les espaces oasiens ? Ces projets, tout en étant porteurs d’objectifs environnementalistes, attestent d’une modalité de qualification du sol et de son exploitation qui tend à éclipser la présence de ces femmes, négligeant au passage l’arrière-plan cosmologique foisonnant sur lequel se dessinent leurs gestes attentionnés et la perméabilité sensible à l’univers végétal oasien dont elles sont les gardiennes.
Affordances sensorielles
Authors: Dassié Véronique
Published: November 2020

Qu’il s’agisse de souvenirs domestiques, d’objets intimes et obsolètes auxquels l’individu est attaché, d’éléments prestigieux du patrimoine monumental, emblématiques des groupes qui les revendiquent, ou encore d’une nature en péril, au nom de laquelle chacun peut s’engager, le monde matériel mobilise les sens et les affects. À la faveur de diverses enquêtes ethnographiques menées en France depuis les années 2000 sur la conservation du patrimoine domestique, les émotions patrimoniales et la patrimonialisation des mémoires des migrations, cet article analyse la manière dont les individus mobilisent les affects pour façonner leur autoportrait. Les épiphanies affectives passent par des expériences sensorielles, véritables épreuves des sens. Mais l’emprise des choses du quotidien, leur affordance et l’affection qu’elles inspirent ne se limitent pas à l’individu concerné, allant bien au-delà. Leur dimension collective se déploie à deux niveaux : action revendiquée de sauvegarde du temps qui passe d’une part, action invisible, voire inconsciente d’une perpétuelle reformation du monde d’autre part. Elle amène à considérer la portée politique des liaisons affectives et de leur interprétation sensorielle sous l’angle d’un autoportrait collectif, miroir d’un monde habité malléable.

Rêves de béton et ontologies relationnelles dans une banlieue mozambicaine (note de recherche)
Authors: Archambault Julie Soleil
Published: November 2020

Cette note de recherche se penche sur les expériences sensorielles de jeunes Mozambicains tandis qu’ils négocient la relation entre bâtir et habiter. J’estime que ces expériences sont intéressantes en soi ainsi que pour ce qu’elles révèlent de la relation entre le monde matériel, les subjectivités et le contexte sociohistorique. Dans ce projet de recherche, j’appréhende, à travers le prisme du ciment, les transformations socioéconomiques en cours dans un continent contentieusement décrit comme étant en plein essor et les implications de ces discours sur la vie de tous les jours des Mozambicains. Inspirée par la lignée croissante des anthropologues qui ont tenté de concevoir les relations entre humains et objets en termes d’ontologies relationnelles, je m’attarde ici à la relation de mutualité entre la maison et l’individu. Comme nous l’enseigne l’anthropologie sensorielle, c’est aussi à travers ledwelling(l’habiter) que l’on forge normes et valeurs culturelles, de sorte qu’une attention particulière portée aux expériences sensorielles met en relief ce à quoi on accorde valeur et importance. Si bâtir et habiter sont souvent conçues comme des activités fondamentalement politiques, l’accent mis sur la relation entre matérialité, temporalité et sensorialité ajoute texture et complexité aux aspirations qui les sous-tendent.
Manger au Ferlo (Sénégal)
Authors: Ka Abdou
Published: November 2020

Les villages où l’auteur a recueilli les données alimentaires dont il est question dans cet article se situent dans la zone sylvopastorale et semi-aride du Ferlo, au nord du Sénégal. Les projets de développement et de lutte contre la désertification s’y suivent depuis les années 1970. La population est majoritairement peule, mais certaines familles sont également wolofs ou maures. À partir d’une enquête ethnographique approfondie, l’auteur met en lumière les tensions que suscite l’introduction de produits alimentaires industriels venus de Dakar ou de l’étranger dans ce Ferlo autrefois habitué à l’autosubsistance (mil, lait, plantes alimentaires sauvages). Il insiste sur la valeur symbolique de ces produits, mais aussi sur leurs ambivalences. Ainsi, le riz et le bouillon cube venus de l’extérieur sont tous deux porteurs de risques sanitaires compte tenu de leur apport excessif en sucre et en sel. L’auteur s’interroge en creux sur les nouvelles formes de dépendance alimentaire que cette situation induit.

Most sanitation movements in the world are physical, local-based, and limited to several beneficiaries in the near proximity of the sanitation project. Social networking sites, such as web 2.0, Facebook, YouTube, and Twitter, help to contribute to the reinvention of social activism, making sanitation movement more accessible and available for everyone despite of geographical constraint. This paper aims to analyze the role of social networking sites in shaping the character, the strategy, and the scope of sanitation movement charity: water, using the concept of social movement and social networks.This paper concludes that social networking sites contribute in shaping the charity: water movement to be platform-based and simpler to every users and activists in term of the character of movement. It shapes its strategy to be the platform to connect and mobilize people from around the world, making it accessible for international activists and beneficiaries. Social networking sites enable activism to reinvent itself.//
Effect of electrolyte concentration on effective surface charge of colloidal particles

The effective surface charge of colloid particles is an important parameter that determines the colloidal properties. However, it is still unclear whether the solvent environment (such as the electrolyte concentration) can affect the effective surface charge. Due to complicated effects relevant to the effective surface charge, such as the exchange of dissociable ions between the electrolyte and surface groups of polystyrene particles, the coupling effect of incomplete ionization of the surface groups of the particles and the adsorption of ions by colloidal particles, etc., it is rather difficult to accurately measure the surface charge and understand the mechanism of charge variation with solvent environment. To solve this problem, we measure the conductivities of polystyrene colloidal particles of carboxyl groups and sulfonic acid groups at various particle number densities and HCl concentrations. Since the cations generated from the two kinds of particles and HCl solution are all H+ cations, the surface charge can be obtained by the conductivity-number density method (migrant method), no matter whether the cation exchanges occur between ionized positive ions of the electrolyte and colloidal particles. Based on the experimental results, the influences of HCl concentration and particle number density on the surface charge of colloidal particles are detected, and the reasons of the influence are analyzed. It is found that the change of the surface charge of the particles of carboxyl group with HCl concentration is faster than that of sulfonic acid group with the HCl concentration. For the same electrolyte concentration, the effective surface charge of carboxyl modified colloidal particles is related to the particle number density, while the charge of sulfonic modified particles is not. Considering the fact that the sulfonic acid group and carboxyl group are strong and weak acid groups respectively, the ionization of H+ cations of the two different groups have profound influences on the cation replacement process, and affect the trend of the curve of the conductivity-particle number density. This effect further results in different change tendencies of effective surface charge with HCl concentration and particle number density. According to the theoretical model as described in this study, all experimental results are well explained. The mechanisms described in this article will be useful for stating the influencing factors of the surface effective charge, and the application of the effective charge to different phenomena relating to interparticle interactions with different parameters of solutions.

Marine organisms are important to global food security as they are the largest source of animal proteins feeding mankind. Genomics-assisted aquaculture can increase yield while preserving the environment to ensure sufficient and sustainable production for global food security. However, only few high-quality genome sequences of marine organisms, especially shellfish, are available to the public partly because of the difficulty in the sequence assembly due to the complex nature of their genomes. A key step for a successful genome sequencing is the preparation of high-quality high molecular weight (HMW) genomic DNA. This study evaluated the effectiveness of five DNA extraction protocols (CTAB, Genomic-tip, Mollusc DNA, TIANamp Marine Animals DNA, and Sbeadex livestock kits) in obtaining shrimp HMW DNA for a long-read sequencing platform. DNA samples were assessed for quality and quantity using a Qubit fluorometer, NanoDrop spectrophotometer and pulsed-field gel electrophoresis. Among the five extraction methods examined without further optimization, the Genomic-tip kit yielded genomic DNA with the highest quality. However, further modifications of these established protocols might yield even better DNA quality and quantity. To further investigate whether the obtained genomic DNA could be used in a long-read sequencing application, DNA samples from the top three extraction methods (CTAB method, Genomic-tip and Mollusc DNA kits) were used for Pacific Biosciences (PacBio) library construction and sequencing. Genomic DNA obtained from Genomic-tip and Mollusc DNA kits allowed successful library construction, while the DNA obtained from the CTAB method did not. Genomic DNA isolated using the Genomic-tip kit yielded a higher number of long reads (N50 of 14.57 Kb) than those obtained from Mollusc DNA kits (N50 of 9.74 Kb). Thus, this study identified an effective extraction method for high-quality HMW genomic DNA of shrimp that can be applied to other marine organisms for a long-read sequencing platform.

Background: Improper and uncoordinated healthcare waste management (HCWM) practice exposes the healthcare worker, patients and surrounding communities to several morbidities and mortality from nosocomial infections.

Objectives: This study aims at assessing waste management services in public and private healthcare facilities at the three levels of healthcare delivery in Enugu State.

Methods: A cross-sectional study using quantitative and qualitative data collection methods involving healthcare workers and healthcare facilities (public and private) at the three levels of care in Enugu state. The study comprised of a total of 23 health facilities and 362 health workers drawn from the three levels of healthcare for private and public facilities.

Data were analyzed using Statistical Package for Social Sciences (SPSS) version 16.0. Chi-square test was used to compare the proportion of healthcare workers with adequate knowledge of HCWM. A significance level of p < 0.05 was used for statistical calculations. Results: One hundred and eighty (47.5%) of the respondents knew the correct steps for HCWM. Most respondents 355(93.7%) admitted that there is associated risk in handling waste. About 147 (38.8%) sustained injury while they had contact with waste out of which 57(38.8%) have had this injury more than three times. The presence of written strategy was higher in public facilities compared to private facilities (x2 = 1.446; p = 0.485), The access to it was highest in the unit (x2 = 1.027; p = 0.311). The frequency of waste collection was highest on a daily basis in both private and public facilities. Waste measurement and segregation were also observed to be higher in public than private facilities (x2 = 1.434; p = 0.488 and x2 = 1.644; p = 0.440 respectively). More public facilities segregated their waste at source compared to private facilities and this was statistically significant (x2 = 13.875; p = 0.008).

Conclusion: The frequency of waste collection was highest on a daily basis in both private and public facilities. However, waste measurement and segregation were observed to be higher in public than private facilities. More public facilities segregated their waste at source compared to private facilities. There seems to be a gap in communication among those involve in health management waste. The health personnel despite level of education and cadre, have poor knowledge of the risk associated with healthcare waste.

This study investigates the effect of post‐heat treatments (solution treatment + aging [SA] and hot isostatic pressing + aging [HIPed]) on the tensile property as well as the room temperature and cryogenic impact toughness of Inconel 718 alloy manufactured by selective laser melting (SLM). The porosities of the three specimens measure SLM SA: 1.10% and SLM HIPed: 0.06%, and wrought SA: 0.01%. Initial microstructural observation shows γ″ + γ′ phase in all three alloys (SLM SA, SLM HIPed, and wrought SA). SLM SA and wrought SA show δ phase of greater fraction compared with SLM HIPed. SLM HIPed and wrought SA show a generally uniform microstructure, and equiaxed grains are found. In tensile tests, SLM HIPed shows greater strength compared with that of wrought SA, but SLM SA shows lowest yield strength among them. The elongations of SLM alloys are ≈1/3 of that of wrought SA. An impact test result shows that impact toughness value at cryogenic temperature of SLM HIPed alloy shows 80% of that of wrought SA. However, SLM SA shows relatively lower impact toughness. In addition, this study attempts to identify the deformation behavior and fracture mechanism of SLM Inconel 718 alloy based on the microstructural characteristics.

Vast wastage of pesticides has caused significant environmental pollution and economic loss, which occurs in any step during the entire process of pesticide application. However, the existing strategies for controlling pesticide losses are step specific. Here, a comprehensive strategy to substantively improve pesticide efficiency on the basis of precise designs from beginning to end is developed. A water‐based coacervate with synthesized imine‐based dynamic covalent trimeric surfactants to synergistically control encapsulation, deposition, retention, and release of pesticides on water‐repellent plants is constructed. The coacervate consists of nanosized networks and abundant tightly bonded water, leading to effective encapsulation of hydrophilic/hydrophobic pesticides. Meanwhile, the network‐like microstructure entangles with the micro/nanostructures of superhydrophobic surface, ensuring complete deposition on superhydrophobic plant surface after high‐speed impact and inhibition of wind/rainwater erosion. Moreover, the CO2‐induced degradative surfactant coacervate determines the precise pesticide release. The dynamic coacervate as an innovative pesticide formula provides a prospective way for pesticide application, and is expected to promote productive and sustainable agriculture.

With the wide utilization of antibiotics, antibiotic‐resistant bacteria have been often developed more frequently to cause potential global catastrophic consequences. Emerging photothermal ablation has been attracting extensive research interest for quick/effective eradication of pathogenic bacteria from contaminated surroundings and infected body. In this field, anisotropic gold nanostructures with tunable size/morphologies have been demonstrated to exhibit their outstanding photothermal performance through strong plasmonic absorption of near‐infrared (NIR) light, efficient light to heat conversion, and easy surface modification for targeting bacteria. To this end, this review first introduces thermal treatment of infectious diseases followed by photothermal therapy via heat generation on NIR‐absorbing gold nanostructures. Then, the usual synthesis and spectral features of diversified gold nanostructures and composites are systematically overviewed with the emphasis on the importance of size, shape, and composition to achieve strong plasmonic absorption in NIR region. Further, the innovated photothermal applications of gold nanostructures are comprehensively demonstrated to combat against bacterial infections, and some constructive suggestions are also discussed to improve photothermal technologies for practical applications.
