Potential Applications of Microparticulate-Based Bacterial Outer Membrane Vesicles (OMVs) Vaccine Platform for Sexually Transmitted Diseases (STDs): Gonorrhea, Chlamydia, and Syphilis
Authors: Chbib Christiane , Shah Sarthak M. , Gala Rikhav P. , Uddin Mohammad N.
Published: October 2021

Sexually transmitted diseases (STDs) are a major global health issue. Approximately 250 million new cases of STDs occur each year globally. Currently, only three STDs (human papillomavirus (HPV), hepatitis A, and hepatitis B) are preventable by vaccines. Vaccines for other STDs, including gonorrhea, chlamydia, and syphilis, await successful development. Currently, all of these STDs are treated with antibiotics. However, the efficacy of antibiotics is facing growing challenge due to the emergence of bacterial resistance. Therefore, alternative therapeutic approaches, including the development of vaccines against these STDs, should be explored to tackle this important global public health issue. Mass vaccination could be more efficient in reducing the spread of these highly contagious diseases. Bacterial outer membrane vesicle (OMV) is a potential antigen used to prevent STDs. OMVs are released spontaneously during growth by many Gram-negative bacteria. They present a wide range of surface antigens in native conformation that possess interesting properties such as immunogenicity, adjuvant potential, and the ability to be taken up by immune cells, all of which make them an attractive target for application as vaccines against pathogenic bacteria. The major challenge associated with the use of OMVs is its fragile structure and stability. However, a particulate form of the vaccine could be a suitable delivery system that can protect the antigen from degradation by a harsh acidic or enzymatic environment. The particulate form of the vaccine can also act as an adjuvant by itself. This review will highlight some practical methods for formulating microparticulate OMV-based vaccines for STDs.
Recognizing and Mitigating Canine Stress during Animal Assisted Interventions
Authors: Townsend Lisa , Gee Nancy R.
Published: October 2021

Animal-assisted Interventions (AAI) proliferated rapidly since clinicians and researchers first noted the positive effects animals have on people struggling with physical and mental health concerns. The intersection of AAI with the field of animal welfare evolved from considering animals’ basic needs, such as freedom from pain, to recognition that animals experience nuanced emotions. Current conceptualizations of the various roles of companion animals as an adjunct to treatments for humans emphasize not only the animals’ physical comfort and autonomy, but also their mental well-being and enjoyment of AAI activities. However, numerous challenges to effective monitoring of animals involved in AAI exist. This article focuses specifically on dogs, highlighting factors that may lead handlers and therapists to miss or ignore canine stress signals during human-animal interactions and offers strategies to recognize and ameliorate dogs’ distress more consistently. The primary goals of this discussion are to summarize the current thinking on canine well-being and to highlight practical applications of animal welfare principles in real-world AAI settings. The paper highlights contextual factors (e.g., physical setting, patient demand), human influences (e.g., desire to help), and intervention characteristics (e.g., presence or absence of a dog-specific advocate) that may promote or inhibit humans’ ability to advocate for therapy dogs during AAI activities. Deidentified examples of each of these factors are discussed, and recommendations are provided to mitigate factors that interfere with timely recognition and amelioration of canine distress.

Authors: Jahn Nicole , Rodrigues Gerzson Laís , Skilhan de Almeida Carla
Published: October 2021

Introdução. Há associação entre a prematuridade (PMT) extrema e a Paralisia Cerebral (PC). No entanto, o Sistema Nervoso Central é plástico, se adapta e se reorganiza, frente a possíveis alterações. Assim, intervenção precoce auxilia na aquisição dessas habilidades motoras. Objetivo: Comparar a aquisição de habilidades motoras no desenvolvimento de bebês prematuros extremos com e sem PC, à intervenção precoce. Método. Retrospectivo, composto por dez bebês prematuros extremos (seis sem PC quatro com PC). Os testes t-student, o teste de Mann-Whitney e o teste exato de Fisher foram utilizados, considerando p≤0,05. Resultados. Quando associado peso, comprimento e perímetro cefálico ao nascer, Apgar no 1º e 5º minuto, dias na Unidade de Terapia Intensiva, e ventilação mecânica com a idade de aquisição das habilidades motoras, observou associação negativa estatisticamente significativa entre peso ao nascer e idade de aquisição motora de rolar. Quanto maior o peso ao nascer e o Apgar no 5º minuto, menor a idade de aquisição da habilidade motora de rolar. Também, quanto maior a nota do Apgar no 5º minuto, menor a idade de aquisição da habilidade motora de engatinhar. Não houve diferença entre os grupos quanto à idade corrigida de aquisição motora, apenas deambular até 15 meses, onde os PMT com PC não conseguiram atingir esta habilidade, bem como a mediana em meses no deambular entre os grupos, onde a idade em meses dos PMT com PC foi significativa. Conclusão. A PMT extrema não se mostrou como a razão de maior interferência no desenvolvimento do bebê, e sim, ter PC.

INFLUENCE OF THE CHEMICAL COMPOSITION OF LIMESTONE ON THE DEVELOPMENT OF MINING WORKS IN QUARRY
Authors: Brašnjić Benjamin , Osmanović Dean
Published: October 2021

There are only a few limestone mines in Bosnia and Herzegovina that provide the mineral raw material for industrial production. As a result, the experience in planning and designing such quarries is lesser than in designing the quarries for construction. Limestone from "Vijenac" deposit is an industrial mineral raw material, which is used for the production of soda (light, heavy and bicarbonate), cement, nitrogen fertilizer named "KAN", and is also used in construction and road construction. The use of limestone as a mineral raw material in industrial production requires more attention to the chemical composition of limestone than to the physical-mechanical characteristics. The paper presents a solution to this problem by creating a block of models of exploitation reserves of limestone, which enables foresight of the chemical composition of limestone, both in each floor partially and during the period of exploitation. The block model was created on the basis of the updated state of works, the projected contour of limestone surface mine and the exploration works' database. The block model uses the following: CaCO3, CaO, SiO2, Al2O3, Fe2O3, bulk density, category of reserves and the purpose of the mineral raw material, i.e. for industry or construction. The block model analysis has determined that the northern part of the mine, from the floor E-612.5 to E-525 meters a.s.l., does not meet industrial requirements in terms of chemical composition of limestone. Therefore, limestone from this part of the surface mine will be used for construction purposes. These quantities of limestone are about 2.6x106 m3. Limestone from the southern part of the surface mine meets the industry requirements. Its quantities are about 8.47x106 m3.

Published: October 2021

The epidemiological significance and biological character of Triatominae are frequently explored, but errors in morphological terminology are common. We discuss the importance of using morphological terminology correctly. The incorrect use of the term “wing” to describe the hemelytron in the study of Triatominae is pointed out. The correct and standard use of the term hemelytron (pl. hemelytra) to describe the forewings is suggested.

Influence of collector doping setback in the quantum transport characteristics of GaN/AlN resonant tunneling diodes
Authors: Encomendero Jimy , Protasenko Vladimir , Jena Debdeep , Xing Huili Grace
Published: October 2021

Harnessing resonant tunneling transport in III-nitride semiconductors to boost the operating frequencies of electronic and photonic devices, requires a thorough understanding of the mechanisms that limit coherent tunneling injection. Towards this goal, we present a concerted experimental and theoretical study that elucidates the impact of the collector doping setback on the quantum transport characteristics of GaN/AlN resonant tunneling diodes (RTDs). Employing our analytical model for polar RTDs, we quantify the width of the resonant-tunneling line shape, demonstrating that the setback helps preserve coherent injection. This design results in consistently higher peak-to-valley-current ratios (PVCRs), obtaining a maximum PVCR = 2.01 at cryogenic temperatures.

Published: October 2021

Intra Uterine Device (IUD) is one of the widely used reversible methods of female contraception. There are many complications reported with IUD
insertion, among which device migration and delayed perforation of viscera like small bowel is one of the rare and serious complication. Here we
report a case of 29 year old female who presented with sudden onset of abdominal pain associated with vomiting. Her Computed Tomography (CT)
scan of abdomen revealed IUD lying within peritoneal cavity causing terminal ileal perforation. She was treated surgically and she recovered well.
Extra uterine visceral organ injury many months or years following IUD insertion is rare and should be considered as a differential in any female
with IUD presenting with abdominal symptoms.

Toward unraveling multi-objective optimization problems: A hybrid approach for solving a novel facility location problem
Authors: Ferdowsi Arman , DehghanChenary Maryam , Jolai Fariborz , Tavakkoli-Moghaddam Reza
Published: October 2021

The focus of this paper is to provide an authentic approach to solving bi-objective optimization problems. The target problem is a novel extension of a multi-period $p$-mobile hub location problem, which takes into account the impact of the traveling time at the hubs' network, the time spent at each hub for processing the flows, and the delay caused by congestion at hubs with specific capacities. We first develop a mixed-integer mathematical model corresponding to the context problem. Afterward, a hybrid meta-heuristic algorithm will be proposed to solve the unveiled model that operates based on simultaneously employing a novel evaluation procedure, a clustering technique, and a genetic approach. The experiments validate that the proposed algorithm performs significantly better than several state-of-the-art algorithms. Furthermore, the decisive effect of two considerable factors: congestion and service time, are also analyzed.

Published: October 2021

Indonesia is an endemic area for the spread of one of the most popular ornamental fish, namely the largest betta fish in the world. In exploring their hobbies such as raising ornamental fish such as betta fish, efficient and automatic tools are more needed by betta fish farmers in aquariums today, when they have no free time or are drained by other work. This study aims to be a more automatic and efficient tool for everyone to feed fish, provide lighting, and drain aquarium water automatically, so that owners of ornamental fish do not have to worry about what ornamental fish need in the aquarium. The feeding system, in this case uses an Arduino-based control that controls the servo motor as an open and close system as the exit of fish feed into the aquarium. Aquarium lighting system, in this system uses a light sensor type LDR (Light Dependent Resistor). Automatic aquarium drain system, controlled by Arduino with water pump output. In the research, the LDR sensor will give a signal to the relay and give output to the 220 V lamp, that is, if the light intensity is below 028.7 Lux, which is above half past 6 pm and will turn off the 220 volt lamp if the light intensity is above 203.4 Lux, which is above 6 am. The servo motor will operate twice a day for feeding according to the betta fish feed needs, which is 2 times a day. The water pump will work every 4 days to drain the water automatically according to the turbidity of the water based on the time and number of betta fish in the aquarium.
The Case of the Dishonest Scrivener: Gouverneur Morris and the Creation of the Federalist Constitution
Authors: Treanor William
Published: October 2021

At the end of the Constitutional Convention, the delegates appointed the Committee of Style and Arrangement to bring together the textual provisions that the Convention had previously agreed to and to prepare a final constitution. Pennsylvania delegate Gouverneur Morris drafted the document for the Committee, and, with few revisions and little debate, the Convention adopted Morris’s draft. For more than two hundred years, questions have been raised as to whether Morris covertly altered the text in order to advance his constitutional vision, but modern legal scholars and historians studying the Convention have either ignored the issue or concluded that Morris was an honest scrivener. No prior article has systematically compared the Committee’s draft to the previously adopted resolutions or discussed the implications of those changes for constitutional law.

This Article undertakes that comparison. It shows that Morris made fifteen significant changes to the Constitution and that many of the Constitution’s central elements were wholly or in critical part Morris’s work. Morris’s changes strengthened the national executive and judiciary, provided the textual basis for judicial review, increased presidential accountability through an expansive conception of impeachment, protected private property, mandated that the census report reflect “actual enumeration,” removed the constitutional text suggesting that slavery was just, and fought slavery’s spread.

This Article also shows that Morris created the basis for the Federalist reading of the Constitution. Federalists—notably including fellow Committee member Alexander Hamilton—repeatedly drew on language crafted by Morris as they fought for their vision of the Constitution. Because the changes Morris made to the Convention’s agreed language were subtle, both Republicans and Federalists were able to appeal to text in the great constitutional battles of the early republic. Modern originalists claim that the Republican reading reflects the original understanding of the Constitution, but this Article argues that the largely dismissed Federalist reading explains words, phrases, and punctuation that the Republican reading ignores or renders unintelligible. By contrast, the Federalist reading of the Preamble (which they saw as a grant of substantive power), the Article I and Article II Vesting Clauses (which were contrasted to argue for expansive executive power), the Article III Vesting Clause (which they read to mandate the creation of lower federal courts), the Contracts Clause (which they read to cover public as well as private contracts), the Impeachment Clause (which they read to cover both nonofficial and official acts), and the “law of the land” provision (which they construed as a basis for judicial review) gives effect to Morris’s—and the Constitution’s—words.
The Missing Algorithm: Safeguarding Brady Against the Rise of Trade Secrecy in Policing
Authors: Won Deborah
Published: October 2021

Trade secrecy, a form of intellectual property protection, serves the important societal function of promoting innovation. But as police departments across the country increasingly rely on proprietary technologies like facial recognition and predictive policing tools, an uneasy tension between due process and trade secrecy has developed: to fulfill Brady’s constitutional promise of a fair trial, defendants must have access to the technologies accusing them, access that trade secrecy inhibits. Thus far, this tension is being resolved too far in favor of the trade secret holder—and at too great an expense to the defendant. The wrong balance has been struck.

This Note offers three contributions. First, it explains the use of algorithms in law enforcement and the intertwined role of trade secrecy protections. Second, it shows how trade secrecy clashes with the Due Process Clause—the Constitution’s mechanism for correcting the power asymmetry between the state and the defendant—and argues that due process should not waver simply because a source of evidence is digital, not human. Third, it proposes a solution that better balances a defendant’s due process rights with intellectual property protections.
Separating the apples from the oranges: from NAFLD heterogeneity to personalized medicine
Authors: Lonardo Amedeo
Published: October 2021

Recently, Arrese and Colleagues have published a review article entitled, “Insights into Nonalcoholic Fatty-Liver Disease (NAFLD) Heterogeneity” (Semin Liver Dis. 2021;41:421-34. doi: 10.1055/s-0041-1730927). This milestone publication clearly and exhaustively explains the multitude of pathogenic pathways involved in the development and progression of disease eventually conducive to heterogeneous clinical phenotypes and different disease outcomes. The present commentary first briefly discusses the biological grounds of NAFLD heterogeneity and then illustrates the work by Arrese et al. In conclusion, the presently adopted nomenclatures appear inadequate in rendering the complexity of disease in the individual patient. In order to adopt the principles of personalized care, what remains to be done is to propose and validate a simple and accurate classification system. This should give full consideration to the principal disease modifiers and should shape a scheme to be adopted in both clinical practice and in the research arena. Care should be taken to not neglect the systemic nature of disease.

Authors: Aslan Keziban , Atasoy Nurhayat , Yoruk Ibrahim Hakki
Published: October 2021

Hormones and Vitamins are extremely important ingredients for healthy growth, development, and regularity of events in metabolism. In our study, it is aimed to compare melatonin hormone and vitamins A, E, D3 of goats, sheep and cows milk. Our sample consisted of 20 Simental Breed Cows, 20 Akkaraman Sheeps, and 20 Native Breeder Goats. Melatonin hormone was analyzed with Enzyme Plate Reader by using Rel Assay branded kit and to determine vitamin�s levels high-performance liquid chromatography (HPLC). Goat milk melatonin level was at the highest level at night and summer. Regarding goats` milk, Retinol and tocopherol levels were higher in spring than in summer. Regarding sheep�s milk, the melatonin level in the sheep`s milk was most elevated at night and spring. There were also statistically significant differences between spring and summer milk of sheep in terms of Retinol, Tocopherol, and Vitamin D3. Retinol and tocopherol levels were higher in spring than in summer, but vitamin D3 was higher in summer than in spring. Regarding cow`s milk, the amount of melatonin in milk was highest in winter and least in autumn. The amount of melatonin in spring was found to be higher than the amount of melatonin in summer. The amount of melatonin in spring was near to the amount of melatonin in winter, so there was not a statistical significance between them, and the amount of melatonin in summer was near to the amount of autumn, and no statistical significance was found between them.
Understanding the Chemical Reactivity of Dihydroxyfumaric Acid and its Derivatives through Conceptual DFT
Authors: Duca Gheorghe , Bolocan Natalia
Published: October 2021

The chemical reactivity descriptors have been calculated through Molecular Electron Density Theory encompassing Conceptual DFT. The validity of �Koopmans� theorem in DFT� (KID) has been assessed by a comparison between the global descriptors (electronegativity, total hardness, and global electrophilicity) calculated through vertical energy values and those arising from the HOMO and LUMO values. These results suggest that the KID procedure is valid and may be used, in conjunction with the B3LYP/3-611G(d, p) level of theory in further studies of related compounds in the aqueous medium. The active sites for nucleophilic and electrophilic attacks have been identified and verified using the local reactivity descriptors: the dual descriptor, the electrophilic and nucleophilic Parr functions, the local reactivity difference index Rk and MEP maps. Obtained results suggest that the antioxidant/antiradical power of investigated compounds may be explained by the highest ambiphilic activation of the oxygen atoms of the hydroxyl groups in the ene-diol moiety.

The problems of security and interests of Russia and China in the Persian gulf region
Authors: Khlopov O.
Published: October 2021

The article analyses the diplomatic, economic and energy interests of China and Russia in the Middle East. In recent years the role the two countries has been increased in this region, and arms sales, trade and cooperation with the Arab countries of the Persian Gulf are very important for the Russian Federation and the PRC today than in the past.

Despite the fact that China has a relatively recent presence in the region, given the various mega-projects, the growth and influence of the PRC on the world stage, its relations with the countries of the Middle East are expanding. The author argues that within the framework of their initiatives, Russia and China have similar and competing interests. This requires from the both countries to coordinate position over the formation of a collective security system in the Persian Gulf region, and more engagement of China in solving the political problems of the region.

Currently applied partial reforestation in cuttings and removal of stumps by uprooting have a number of significant technological, environmental and economic disadvantages. These are removal of the humus layer of soil outside the cleared strips, compaction and reduction of soil porosity; formation of understump holes and their local waterlogging; littering of noncleared belts of trees between strips with felling debris and uprooted stumps; low productivity of uprooting machines and high energy consumption of stump uprooting; termination of agrotechnical tending after 2–3 years after planting and impossibility of cleaning stands due to their obstruction for tractor units; low level of traction force of special forest tractors and their insufficient power for uprooting stumps. Technology, machines and tools for reforestation in cuttings become the subjects of the research. The aim of the research is to provide a comprehensive mechanization of the reforestation process in order to improve work productivity, reduce energy and material consumption of the technology and create conditions for the effective use of machines and tools in combination with energy-efficient tractors of the traction-energy concept, ensuring the elimination of harmful effects on soil and plants ecology. The results of achieving the set aim and objectives are substantiation of forestry and ecological, technical, and economic feasibility of using the technology based on the complete clearing of cuttings from felling residues, dead wood and coppice of shrub vegetation by their crushing using mobile mulchers; removal of stumps in cuttings through crushing them at a depth of 0.15–0.20 m by an upgraded MUP-4A machine with scattering chips over the planting area and subsequent continuous tillage with a disk harrow BDK-2.5. Harmful effects on the ecology of soil and plants are practically eliminated with an increase in productivity, and the grinded woody biomass mixed with the soil turns into an organic fertilizer. The elimination of mechanical obstacles such as felling residues, fallen trees and stumps makes it possible to effectively use energy-efficient tractors by combining technological operations and performing them in one pass of the unit, as well as increasing the working width and operating speeds. Conditions for efficient operation of forestry machines and tools on tractormotor traction to protect the forest from pests, diseases, and fires, and for mechanization of various types of thinning are being created.

Im Umfeld von Industrie 4.0 halten die modernen Informationstechnologien immer stärker Einzug. Dabei sind Schlüsseltechnologien wie zum Beispiel künstliche Intelligenz (KI) oder Artificial Reality (AR) für sich allein genommen im industriellen Praxiseinsatz nur sehr bedingt verwendbar. Den Schlüssel zum Erfolg liefert vielmehr die Vernetzung dieser modernen Technologien sowohl untereinander als auch mit dem humanen Bedienpersonal durch Algorithmen und Systeme zur Mensch-Maschine-Kollaboration (MMK).

 

In modern times of Industry 4.0 innovative technologies become more and more important, but key-technologies like Artificial Intelligence (AI) and Artificial Reality (AR) need to be combined in the practical field of human working processes. The key to success is delivered by Man-Machine-Collaboration (MMC) algorithms and systems.

Die mechanische Nachbearbeitung von Propellergussrohlingen im Schiffbau ist ein manuell geprägter, zeitintensiver Bearbeitungsschritt. Eine Automatisierungslösung ist mithilfe eines Großroboters aufgrund seiner Tragfähigkeit und seines Arbeitsraumes möglich [1]. Um Positionsfehler und Schwingungsanfälligkeiten des Roboters durch auftretende Prozesskräfte zu vermeiden, sind hochsteife Strukturbauteile notwendig, für deren Entwicklung das Fraunhofer-Institut für Groß- strukturen in der Produktionstechnik (IGP) die Topologieoptimierung einsetzt.

 

The mechanical finishing of propeller casting blanks in shipbuilding is a manually characterized, time-intensive processing step. An automation solution is possible by means of a large robot due to its load-bearing capacity and working space. In order to avoid positioning errors and vibration susceptibility of the robot due to occurring process forces, highly rigid structural components are necessary, for the development of which Fraunhofer IGP uses topology optimization.

Millionen Pakete werden jährlich in Logistikzentren gehandhabt. Um die große Vielfalt unterschiedlicher Kartons abdecken zu können, kommen meist Standard-Greifsysteme mit leistungsfähigen Vakuumejektoren zum Einsatz, die durchgehend bei hohem Überdruck betrieben werden. So wird in den meisten Fällen mehr Energie verbraucht, als benötigt wird. Durch den Einsatz von Machine Learning kann das manuelle, erfahrungsbasierte Einstellen der Prozessparameter eliminiert und Energieeinsparungen von bis zu 70 % erzielt werden.

Bei CNC-gesteuerten Bearbeitungszentren ist das Erfassen der Rohteilposition und -abmessungen im Arbeitsraum der Werkzeugmaschine ein wichtiger Arbeitsschritt beim Rüstprozess vor dem Fräsvorgang. Meist wird zum Einmessen des Rohteils ein Messtaster verwendet, der das Rohteil in seinen X- und Y- Ausmaßen, in der Z-Höhe und der Rotation vermisst und diese Maße an die Steuerung der Werkzeugmaschine übergibt. Im durch die Landes-Offensive zur Entwicklung Wissenschaftlich-ökonomischer Exzellenz („Loewe“) des Landes Hessen geförderten Forschungsvorhaben „Smarte Aufspannkontrolle“ wurde ein Computer-Vision-System entwickelt, dass das Erfassen von Rohteilposition und -abmessungen mit einer Kamera erlaubt und damit den Rüstprozess vereinfacht, beschleunigt und weniger anfällig gegenüber Bedienungsfehler macht.

 

In CNC-Mills, recording the position and dimension of raw parts is a critical part of the process. In modern milling-centres, 3D-Touchprobes are used to detect part dimensions and locations. In the research project „Smarte Aufspannkontrolle“ funded by “Loewe” (Landes-Offensive zur Entwicklung Wissenschaftlich-ökonomischer Exzellenz), a computer vision system (CVS) was developed. The CVS is able to detect part dimensions and locations. Its purpose is to make the part-setup quicker and to lower the risk of human mistakes.

Published: October 2021

Mobile Roboter sind in verschiedenen Bereichen der Industrie zu wichtigen Werkzeugen geworden, insbesondere in der Logistik. Die sichere Navigation in hochdynamischen Umgebungen stellt jedoch weiterhin eine große Herausforderung für klassische Pfadplanungsansätze dar. Deep Reinforcement Learning (DRL) hat sich als alternative Planungsmethode herauskristallisiert, um allzu konservative Ansätze zu ersetzen und verspricht eine effizientere und flexiblere Navigation. Diese Ansätze sind jedoch aufgrund ihrer Anfälligkeit für lokale Minima und das Mangeln eines Langzeitgedächtnisses nicht für die Langstreckennavigation geeignet, was eine breite Integration in industrielle Anwendungen der mobilen Robotik behindert. Dieser Beitrag stellt einen Ansatz für die Integration von DRL-basierter Navigation in existierende Navigationsansätze von industrieller mobiler Robotik vor.

 

Recently, mobile robots have become important tools in various industries, especially in logistics. Deep reinforcement learning emerged as an alternative planning method to replace overly conservative approaches and promises more efficient and flexible navigation. However, deep reinforcement learning approaches are not suitable for long-range navigation due to their proneness to local minima and lack of long-term memory, which hinders its widespread integration into industrial applications of mobile robotics. In this article, we propose a navigation system incorporating deep-reinforcement-learning-based local planners into conventional navigation stacks for long-range navigation of mobile robots.
