Orbital-angular-momentum fluorescence emission based on photon–electron interaction in a vortex field of an active optical fiber
Authors: Wu Yan , Wen Jianxiang , Tang Fengzai , Pang Fufei , Guo Hairun , Huang Sujuan , Wang Tingyun
Published: December 2022

We develop a model of interaction between photons and electrons in an active vortex field, which can generate a fluorescence spectrum with the characteristics of orbital angular momentum (OAM). In an active optical fiber, our findings generalize the notion of photon–electron interaction and point to a new kind of OAM-mode broad-spectrum light source, which could be interpreted in two processes: one microscopically is the excitation of OAM-carrying photons based on the photon–electron interaction; the other macroscopically is the emission and transmission of a donut-shaped fluorescence in a vortex field with a spiral phase wavefront in a ring-core active fiber. Here we present a straightforward experimental method that the emission of broad-spectrum fluorescence with an OAM feature is actualized and validated in a ring-core erbium-doped fiber. The spectrum has a broad spectral width up to 50 nm. Furthermore, four wavelengths are extracted from the fluorescence spectrum and superimposed with their corresponding Gaussian beams, from which the spiral-shaped interferograms of OAM modes in a broad spectrum are identified with high purity. The application of the OAM-based fluorescence light source may range from classical to quantum information technologies, and enable high-capacity communication, high-sensitivity sensing, high-resolution fluorescence imaging, etc.
Digitalisierung als Herausforderung für die Governance sozialer Dienstleistungen – das Beispiel der Sozialen Schuldnerberatung
Authors: Kaps Petra , Reiter Renate , Oschmiansky Frank , Popp Sandra
Published: December 2022

Der Artikel diskutiert anhand der Ergebnisse eines Forschungsprojektes zum Wandel sozialer Dienstleistungen in der Corona-Pandemie Herausforderungen, die sich aus der Digitalisierung sozialer Dienstleistungen für deren Governance durch die Leistungsträger ergeben. Es wird ein Analyserahmen entwickelt und exemplarisch auf die Soziale Schuldnerberatung als freigemeinnützig bereitgestellte soziale Dienstleistung angewendet. Wir unterscheiden drei GovernanceDimensionen: Finanzierung, Organisation und Zugang.

Die Digitalisierung initiiert Prozesse der Trans-Territorialisierung. Die institutionellen Regelungsstrukturen, innerhalb derer die Governance sozialer Dienstleistungen erfolgt, können infolgedessen ihre strukturierenden Effekte nicht mehr voll entfalten. Institutionentheoretisch gesprochen kommt es zu einer „drift“-Situation. Der Artikel diskutiert am Beispiel der Schuldnerberatung, wie dem resultierenden Bedarf institutioneller Anpassung in allen drei GovernanceDimensionen begegnet werden kann.

Based on the results of a recent research project on the transformation of social services during the Corona pandemic, the article discusses challenges arising from the digitalization of social services for their governance by the public service principal. In this context, we develop an analytical framework and apply it exemplarily to social debt counseling as a social service provided by non-profit service providers. We distinguish three governance dimensions: financing, organization and access.

Digitalization sets in motion processes of the trans-territorialization of social services. As a result, the institutional regulatory structures within which the governance of social services has taken place can no longer fully unfold their structuring effects. In terms of institutional theory, this leads to a „drift“ situation.

This article discusses how the resulting need for institutional adaptation can be addressed in all three governance dimensions.
Pigeons and papyrus at Amarna: the birds of the Green Room revisited
Authors: Stimpson Christopher M. , Kemp Barry J.
Published: December 2022

Ancient Egyptian art features many carefully observed depictions of wild animals and birds. A famous example is the late Eighteenth Dynasty (fourteenth-century BC) wall paintings of the Green Room in the North Palace at Amarna, where naturalistic depictions of birds feature prominently. Their taxonomic identity, however, is not resolved in all cases. Here, the authors revisit the facsimiles produced in the 1920s by Nina de Garis Davies. Mindful of previous works, taphonomy and the interplay between naturalistic observation and artistic licence, they employ ornithological resources to conduct a qualitative assessment and propose a parsimonious scheme of identifications, relating the results to long-standing questions concerning ecological and stylistic aspects in the artwork.

Published: December 2022

Natural fillers have been used as reinforcing material for many years in the research field of biobased polymers. It is widely known for being low cost, eco-friendly, and easily available. The biobased polymer composites have strong future prospects in the application for transportation and packaging industries. In this study, the biobased composite is fabricated at 40 % hazelnut shell flour (HSF) content with 2.5, 7.5, and 10 % of inorganics-based additives like mica, glass ball, talc by extrusion, and press molding method. The mechanical and thermal properties and water absorption of those composites are investigated. The result reveals that inorganic powder-filled composites shows clearly higher impact energy than pure polylactic acid (PLA). However, there was a general decrease in tensile and flexural properties with the addition of mica and glass ball powders, and an increase in properties between 10 % and 30 % was determined with the addition of talc powder (7.5 % and 10 %). The highest flexural strength of the 7.5 % talc-filled PLA/HSF composites is obtained as 51 MPa and the highest tensile strength of 22 MPa was observed for both 7.5 % and 10 % talc. The scanning electron microscopic image reveals the uniformly distributed organic and inorganic fillers and microstructural deformation of the fractured composite surfaces.

Authors: Ali Dler
Published: December 2022

Background and objective: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of coronavirus disease-19 (COVID-19). The effects of COVID-19 on the thyroid axis remain uncertain. This study aimed to determine the occurrence of thyroid dysfunction, as previously demonstrated for SARS-CoV-1 infection, and to analyze electrolytes (sodium, potassium, and chloride) to determine the severity of the disease. Methods: Blood samples were taken from patients who were admitted to Erbil hospitals from July to October 2021. Infection was detected by polymerase chain reaction (PCR). The 306 cases were labeled as moderate or severe. The samples were assessed for doing C-reactive protein (CRP), as a marker of systemic inflammation, thyroid-stimulating hormone (TSH), triiodothyronine (T3) and thyroxine (T4), and (sodium, potassium, and chloride) electrolytes. Results: Patients comprised of 157 (51.3%) males and 149 (48.7%) females. The result revealed that 274 (89.5%), 278 (90.8%), 292 (95.4%) of patients had normal TSH, T3, T4 level respectively, 22 (7.2%), 23 (7.5%), 9 (2.9%) of patients had low TSH, T3, T4 level respectively, and 10 (3.3%), 5 (1.6%), 5 (1.6%), had high TSH, T3, T4 level respectively. There was no significant difference between moderate and severe cases in alterations of TSH, T3, T4 level. There was a significant difference between moderate and severe cases in sodium, potassium, and chloride electrolyte abnormality. Conclusion: The occurrence of thyroid dysfunction in moderate and severe cases. The severity of the COVID-19 infection is associated with abnormalities in sodium, calcium, and chloride electrolytes.

Authors: Mustaqim Tanzilal , Fatichah Chastine , Suciati Nanik
Published: December 2022

Purpose: Acute Lymphoblastic Leukemia (ALL) Detection with microscopic blood images can use a deep learning-based object detection model to localize and classify ALL cell subtypes. Previous studies only performed single cell-based detection objects or binary classification with leukemia and normal classes. Detection of ALL subtypes is crucial to support early diagnosis and treatment. Therefore, an object detection model is needed to detect ALL subtypes in multi-cell blood microscopic images.Methods: This study focuses on detecting the ALL subtype using YOLOV4 with a modified neck using Cross Stage Partial Network (CSPNet) and GhostNet. CSPNet is combined with Spatial Pyramid Pooling (SPP) to become SPPCSP to get various features map before the YOLOv4 final layer. Ghostnet was used to reduce the computation time of the modified YOLOV4 neck.Result: Experimental results show that YOLOv4 SPPCSP outperformed the recall value of 14.6%, the value of mAP@.5 0.8%, and reduced the computation time by 4.7 ms compared to the original YOLOv4.Novelty: The combination of CSPNet and GhostNet for YOLOV4 neck modification can increase the variety of features map and reduce computing time compared to the Original YOLOv4.
Die „regulatory sandbox“ als Regulierungsansatz für FinTechs – eine rechtsvergleichende Analyse
Authors: Roth Otto Maximilian
Published: December 2022

Mit der regulatory sandbox reagieren diverse Rechtsordnungen auf die gewachsene Bedeutung von FinTechs im Finanzdienstleistungssektor und die Frage ihrer Regulierung. Sie steht damit im Mittelpunkt der rechtspolitischen Diskussion um die Notwendigkeit stärker innovationsfreundlicher Regulierungsansätze, die in Deutschland, Europa und international seit Längerem intensiv geführt wird. Der Beitrag beantwortet, warum sich eine regulatory sandbox auch für Deutschland anbietet, um die Innovationskraft des Kapitalmarkts gezielt zu fördern und FinTechs angemessen zu regulieren. Dafür bedient er sich des britischen Rechts als Ausgangspunkt und leitet dann zu einer kritischen Würdigung des Ansatzes aus deutscher Perspektive über. Ein besonderes Ausgenmerk liegt dabei auf dem Zusammenspiel zwischen nationalem und europäischem Bank- und Kapitalmarktaufsichtsrecht und der Frage, auf welcher Ebene sandbox-Modelle umgesetzt werden sollten. Nähere Betrachtung erhält deshalb auch die neue Verordnung über eine Pilotregelung für auf Distributed-Ledger-Technologie basierende Marktinfrastrukturen, die erstmalig eine regulatory sandbox auf europäischer Ebene etabliert und durch die das Thema an zusätzlichem wissenschaftlichen und praktischen Reiz gewinnt.
The Symbiotic Interaction between Industry and Academia in Tertiary Education: A Case Study on Internships
Authors: Busuttil Leonard
Published: December 2022

The misalignment between the skills learned in tertiary education and the skills demanded by industry is well documented. One of the ways this misalignment can be reduced is through the introduction of an internship phase in degrees. This article identifies the perceived benefits and challenges that internship programmes offer academic staff in a tertiary educational facility. It also determines how feedback from the industry helps shape the curriculum of the degree. A qualitative case study is employed through interviews with various staff working at a tertiary education institution. The data generated is analysed using a thematic approach. The results show that internships not only place value on soft skills but also build a communication channel between the mentors that visit students whilst out on placement and the industry staff that oversee the students during the work-based phase. This mutually beneficial interaction between the industry and the education institution helps the mentors maintain familiarity with the latest technologies adopted in the industry and allows the industry to influence the curriculum of the degrees. Internships were shown to offer a means of advertising the skills gained in academia to the audience that would eventually employ the graduates.
How to Deal with the Fabricated Hadith: Some Notes for Hadith Dispersion in Social Media
Authors: Usman Abur Hamdi , Wazir Rosni , Nasir Mohd Norzi
Published: December 2022

In Islam, the fabricated hadith is the least acknowledged hadith. The scholars unanimously reject this hadith and forbid its recitation without identifying its status. Fabricated hadith’s core perversion is its justification for the Prophet Muhammad’s assassination (PBUH). Falsification of hadith has harmed numerous facets of life, including faith, religious legislation, and acts of devotion. Additionally, the number of false hadiths is growing daily. This chilling reality has become a concern due to the widespread dissemination of such hadiths through modern technology. The dissemination of falsified hadiths via social media has emerged as a new issue that new-generation Muslims must take seriously, particularly individual awareness, knowledge, ethics, and morals.This paper will emphasize the hadith’s history and falsification aspects, assess its dispersion tendencies using more advanced media, and recommend many tips for preventing further dissemination. Using a qualitative method, this study found several guidelines to ensure the dispersion of fabricated hadith is handled properly, such as not believing in anything quickly, ensuring authenticity before sharing, and providing advice to admit mistakes in spreading the fabricated hadith. In this regard, we encourage academic scholars to conduct research on fabricated hadiths in order to preserve the purity and authority of the Prophet’s hadiths as the second Islamic source for Muslims.

Published: December 2022

Fuel oil has a deficit every year. Therefore, a substitute fuel is needed, which can be obtained more efficiently. One of the alternative fuels that have been widely researched is biofuel. Catalytic cracking is a method of producing biofuels such as biogasoline (C5-C9), bioavtur (C10-C15) and green diesel (C16-C22). This research aims to produce biofuels by catalytic cracking of palm oil using HCl/γ-Al2O3 and HCl/Ni/γ-Al2O3 catalysts (1, 3, 5 and 7%). The catalyst was prepared by wet impregnation and characterized by x-ray diffraction, Brunauer Emmett teller and ASTM-D664. The reaction cracking process was operated at a constant temperature of 370 °C, 50 ml volume, and 1 atm pressure. The best catalyst for cracking palm oil is HCl/Ni/γ-Al2O3 (5%) with a yield of 81%, selectivity to biogasoline at 6.41%, bioavtur at 33.81%, and green diesel at 20.33%.

Published: December 2022

The emergence of technological sophistication that they are proud of has resulted in the problem of decreasing attitudes and behavior experienced by millennial students. Attitudes caused include a lack of morals, cyberbullying, and gadget addiction. So, changes in behavior must be followed up by Arabic teachers, and the challenge for Arabic teachers in Indonesia is to meet the Era of Society 5.0. This study aims to show that Arabic language teachers and community components must be able to deal with complexities. And teachers must be able to build good and conducive communication with students, parents, and the community. The right step to deal with it is to think and act on a solution because it is part of creative thinking reform. Literature study is one approach in this research. Arabic teachers who think relatively must prepare themselves to face the challenges of society 5.0 using (1) always being optimistic, (2) having a solid work team, (3) being communicative teachers, (4) being hard workers, (5) commitment, (6) simplifying problems, not taking lightly. The author hopes that Arabic language teachers, communities, and stakeholders in Indonesia can together create students with innovative and solutive characters. <w:LsdException Locked="false" Priority="39" SemiHidden="true" Unh

Role of insulin-like growth factor, pro-inflammatory and anti-inflammatory cytokines, transcription factors and adipokines in development of hepatocellular carcinoma in metabolic syndrome
Authors: Smirnova O. V. , Gershkoron F. A.
Published: December 2022

Conflicting data on the role of the metabolic syndrome (MS) in the development of hepatocellular carcinoma (HCC) require studies on the influence of molecular factors that are important in the development of HCC in MS, which was the goal of our review. Publications (scientific articles and reviews) over the past 10 years were studied and analyzed using the databases Web of Science, Scopus, PubMed, RSCI. The terms used for the search were “metabolic syndrome and non-alcoholic fatty liver disease”, “metabolic syndrome and non-alcoholic steatohepatitis”, “metabolic syndrome and hepatocellular carcinoma”. The total number of publications studied in all databases exceeded 570 units, while the review presents the most significant results at the present stage. Insulin resistance and obesity, through the development of a systemic chronic inflammatory state, lead to increased inflammation and fibrosis in the liver, which are prodromal signs of hepatocarcinogenesis, increase the production of insulin-like growth factor-1 and disrupt the regulation of the insulin-like growth factor pathway. People with HCC have been shown to overexpress IGF-2. IGF-binding proteins, due to the reduced bioavailability of free IGF-1 and IGF-2 in the circulation, are able to inhibit the growth of HCC. In MS, a pro-inflammatory state is detected, which is caused by the production of cytokines by adipocytes (IL-6, IL-8, IL-1β, tumor necrosis factor α (TNFα), VEGF and chemokine ligands 2 and 5), which recruit immune cells, promoting angiogenesis and enhancing chronic inflammation. Transcription factors (PPAR) are involved in hepatocarcinogenesis, the significance of different factors is not fully understood. Leptin has a positive prognostic value in HCC, improving overall survival, and visfatin has a negative effect on hepatocarcinogenesis. Activation of PAI-1 inhibits the progression of HCC through PPARγ stimulation. Adiponectin may be a prognostic marker in HCC, with a lower serum concentration positively correlated with worse prognosis.

ABSTRACT: This study describes, through a retrospective study, the epidemiological and clinical-pathological findings of compression in the central nervous system (CNS) of buffaloes. The study includes observations made in 15 animals from 1998 to 2021 by reviewing the clinical records of animals with compressive injuries of the CNS treated at the Veterinary Hospital of the Veterinary Medicine Institute of the Federal University of Pará. The animals treated with clinical signs compatible with CNS compressive lesions were subjected to general and specific clinical examinations of the nervous system. Blood samples were collected from four animals for complete blood counts, and cerebrospinal fluid (CSF) samples were collected from three animals for physical evaluation. Thirteen animals were necropsied. The age range of the affected animals ranged from four months to 11 years of age, with a greater frequency over age 12 months (80%, 13/15). The most affected vertebral segment was between T3 and L3 (60%, 9/15), followed by brain injury (20%, 3/15), the L4-S2 segment (13.3%, 2/15) and the C1-C5 segment (6.7%, 1/15). The clinical findings varied according to the location of the lesion. The necropsy findings revealed paraypophyseal abscess in the brainstem and vertebral body, subarachnoid hematoma, lymphoma and vertebral fractures. The performance of a thorough clinical examination of the CNS combined with the necropsy findings was important to characterize the clinical picture and to locate the cause and the affected CNS segments in the buffaloes studied. It is important to include CNS compressive lesions among the neurological diseases of buffaloes.

Published: December 2022

Resumo O objetivo deste estudo foi avaliar o conhecimento de escolares do ensino médio de três escolas localizadas em municípios mineiros endêmicos para a doença de Chagas e extrair informações relativas à sua percepção em relação aos aspectos gerais, biológicos, clínicos e epidemiológicos da doença, do vetor e controle entomológico da doença de Chagas, além de comparar o conhecimento dos participantes em função da localização das escolas (zona rural ou urbana). Para isso, aplicou-se um questionário semiestruturado a 68 alunos. Todos os participantes já ouviram falar a respeito da doença de Chagas, afirmando ter adquirido esse conhecimento, sobretudo, com familiares e escola. Além disso, muitos participantes demonstraram conhecer os hábitos dos vetores, tais como hematofagia e fontes alimentares. Não houve associação clara entre o perfil de urbanização e o conhecimento dos participantes. No entanto, alunos da zona urbana apresentaram menos conhecimento prático a respeito dos triatomíneos e aspectos relativos à transmissão da doença, em relação aos alunos da zona mais “ruralizada”. Sugere-se o aprofundamento do tema nos currículos escolares do ensino médio e a necessidade de elaboração de ações de educação em saúde voltadas à vigilância entomológica da doença de Chagas nesses municípios e, provavelmente, em outras regiões do Brasil.

Abstract Covid-19 has arisen deep changes in formal Education as a result of a sudden transition from in person to remote Education. Effects in different fields, such as mental health and socioeconomic vulnerability, also need follow up and evaluation. So, this paper aims to analyze the educational inequalities amplified by the pandemics, as well as the remote Education effects on students, educators and families. Its theoretical framework consisted of the reproduction theories and philosophical works on heterotopy, speed and the world and Education digitalization. The results show that previous achievements in schooling access, quality and equality took steps backwards. Mental health and student motivation have suffered negative effects. Digital Education does not seem to keep the same level of outcomes and equality. Therefore, remote Education has implied deep changes in schooling routines and ways of learning, some of them susceptible of negatively affecting students. Remote Education, despite its lower costs and prestigious halo, is to be used cautiously and with parsimony.

Published: December 2022

Many of the international hospitals and health institutions have faced serious financial difficulties with the Covid-19 epidemic that emerged at the end of 2019. In the coming years, these financial difficulties are expected to cause more bankruptcies. Being able to predict company bankruptcies is important to protect company partners, investors, company creditors and the continuity of the healthcare industry. Thanks to accurate forecasts in this area, company managers can prevent company bankruptcies by taking the necessary precautions and investors can limit their losses. This study aims to build a model that can predict bankruptcies in the health sector by using artificial neural networks (ANN). For the sample of this study, 23 companies in the health sector that declared bankruptcy between 01.01.2018 and 31.12.2020 in the USA, and 23 companies that were in the same period and the same sector but had no financial problems were selected as the control group. 30 financial ratios belonging to these companies were used as input data of the research. In the study, artificial neural networks (ANN) were chosen as the method. According to the results of the research, the correct classification rate of the artificial neural network models created using the training set data was 100%. The correct classification rate of artificial neural network models created using test set data was 90%. According to the results of the research, ANNs are promising for the prediction of company bankruptcies with their high classification success and ease of use. Therefore, it is recommended to be used by both researchers and investors.

Introduction. Plasma spraying is one of the modern and effective methods for coatings application for various purposes and compositions. With the help of thermal plasma flows, it is possible to spray almost any powder materials (ceramic, metal, metal-ceramic). Plasma spraying of multilayer protective coatings can be successfully used to increase the durability of pierced mandrels, which are the main tool in the production of hollow billets. The purpose of this work is to study the chemical composition, structure, and microhardness of multilayer high-temperature coatings of two different compositions deposited by plasma spraying, which are supposed to be used to increase the durability of pierced mandrels. Materials and research methods. The deposition of multilayer coatings of two compositions was carried out on a plasma-powder spraying unit with contact excitation of an arc discharge UPN-60KM TSP2017. Coatings were obtained by sequential deposition of three layers with different powder compositions. After deposition of all three coating layers, oxidative annealing was carried out at a temperature of 900°C to form a dense scale layer of FeO + Fe2O3 + Fe3O4 on the surface. The chemical composition of the coatings was studied by X-ray microanalysis using a TESCAN scanning electron microscope with an OXFORD attachment. The microstructure of the coatings was studied using a NEOPHOT metallographic microscope. Phase X-ray diffraction analysis was performed on a SHIMADZU diffractometer in Kα chromium radiation. Microhardness was measured on a LEICA hardness tester at a load of 50 g. Results and discussion. The nature of the distribution of chemical elements over the thickness of the coating, consisting of four layers, is established: an inner metal layer that provides protection against high-temperature corrosion; a transitional metal layer designed to equalize the thermal properties between the layers; α-Fe metal oxide layer and iron oxides and external thermal barrier oxide layer FeO + Fe2O3 + Fe3O4. Coatings are characterized by a non-uniform distribution of structural components and microhardness over its thickness. The microhardness of the inner layer reaches 1,400 HV0.05, the transition layer is 800 HV0.05, and the metal oxide layer is 300 HV0.05.

Introduction. The technology of selective laser melting is one of the key technologies in Industry 4.0, which allows manufacturing products of any complex geometric shape, reducing significantly the amount of material used, reducing the lead time and obtaining a new alloy from elementary powders in the melting process. To understand the process of alloy formation under laser exposure, it is necessary to know the initial data of powders, which significantly affect the quality of the products obtained. The purpose of this study is to determine the requirements for the structural-phase state, elemental composition of aluminum, silicon and magnesium powders and further preparation of Al-Si-Mg (Al — 91 wt.%, Si — 8 wt.%, Mg — 1 wt.%) powder mixture for laser synthesis. The initial powders of aluminum PA-4 (GOST 6058-73), silicon (GOST 2169-69) and magnesium MPF-4 (GOST 6001-79) and powder composition Al-Si-Mg are studied using X-ray diffraction and X-ray phase analysis. The shape and sizes of particles are determined by the studies of raster electronic images. By the method of selective laser melting, samples are obtained from a powder composition under constant and pulsed laser exposure. The composition is prepared by mixing powders in a globe mill. Results and discussion. It is shown that the initial powders of aluminum, silicon and magnesium are single-phase. Particles with a size of 20–64 µm, recommended for selective laser melting, are used to obtain a powder composition. By mixing the powders for one hour, spherical particles are obtained, which is preferable for laser melting. The results of grinding the samples after laser melting showed that the samples obtained under constant laser exposure at the following mode parameters: P = 80 W, V = 300 mm/s, s = 90 μm, h = 25 μm have the greatest mechanical strength. Conclusions. The described study shows the possibility of synthesizing products from a powder composition of aluminum, silicon and magnesium by selective laser melting.

Introduction. Currently, a substantial proportion of the machine-building industry is made up of one-off products or products manufactured in small batches. In this regard, innovative approaches to obtaining such products are being actively applied in order to reduce the cost of special, expensive tooling of the blanking process. Such technologies include the Direct Metal Deposition (DMD) method, the essence of which is the deposition of metal particles from a gas-powder stream. This method has a lot of advantages, but one of the main drawbacks is that the products after growing have a rough surface and do not meet the accuracy requirements of the finished part drawing. Consequently, the parts require further machining by cutting. However, due to the novelty of the materials, there are no regime parameters for machining. In this regard, the aim of the work is to establish the functional relationship between the cutting force and roughness of the machined surface with the feed per tooth during end milling of EuTroLoy 16604 material formed by DMD-method. In this paper an experimental study of cutting force and roughness of machined surface with varying the tooth feed during end milling is carried out. The research method is an experiment on milling of EuTroLoy 16604 material obtained by DMD-method with measuring the output parameters of the process (cutting force and roughness of the machined surface). Results and discussion. The measured values of cutting force and roughness of the machined surface allowed establishing functional and graphical dependences of the output parameters of the milling process on the feed per tooth. It is found that using a cutter with a smaller clearance angle results in lower cutting forces and the surface has a lower height of microroughness. Thus, the developed functional relationships of cutting force and roughness of the machined surface with the feed per tooth allow predicting the output parameters of the cutting process and increasing the efficiency of machining operations by cutting. A promising direction for further work is seen in the study of relative machinability and evaluation of its quantitative value.

A pesar del rico conocimiento que puede ofrecer el estudio sistemático de la carrera político-parlamentaria, este no resulta tan frecuente como en ocasiones se cree. Es, de hecho, una de las temáticas que menos atención recibe por parte de la disciplina, en relación con otras más clásicas. El presente capítulo tiene por objeto abordar el estudio de la carrera parlamentaria en Colombia durante el periodo comprendido entre 1998 y el 2018, asunto poco o nada estudiado en el contexto nacional. En primer lugar, se realizará un recorrido por la literatura relativa a la relación entre la carrera parlamentaria y la calidad de los parlamentarios. En segundo lugar, haciendo uso de los datos disponibles en el marco del Proyecto de Élites Parlamentarias de América Latina de la Universidad de Salamanca, se presentan las principales características sociopolíticas y sociodemográficas de los congresistas colombianos durante el periodo analizado. Posteriormente, siguiendo la tipología propuesta por Martínez (2006), se clasifican en función de su calidad y su experticia. Y finalmente se analiza cómo los diferentes niveles de calidad de los representantes colombianos pueden entenderse como una variable explicativa del voto, más allá de las variables tradicionales, como la ideología y el partido.

¿Cuáles han sido las claves de la evolución partidaria en Colombia durante el periodo 2006-2018? Partiendo de la literatura especializada sobre la funcionalidad de los partidos políticos, evaluamos las dimensiones organizacional, electoral y gubernamental de las organizaciones partidarias colombianas como una aproximación a su evolución en el tiempo tras la reforma del 2003 que reconfiguró el sistema de partidos en el país andino. Inferimos descriptivamente a partir de los datos disponibles en el marco del Proyecto de Élites Parlamentarias de América Latina de la Universidad de Salamanca (España), Latin American Public Opinion Project (LAPOP) de la Universidad de Vanderbilt (Estados Unidos) y de Varieties of Democracy (V-Dem) de la Universidad de Gotemborg (Suecia) que los partidos políticos colombianos han tenido un débil enraizamiento en la sociedad, son fluidos ideológicamente –salvo aquellos que han ejercido la oposición– y han apostado por una disciplina partidaria híbrida caracterizada por combinar decisiones de bancada y decisiones individuales de los legisladores como factores que explican su trayectoria en el periodo de estudio.

Toxoplasma gondii is a ubiquitous zoonotic food-borne parasite [1]. Nearly one-third of the world’s population has been exposed to the parasite, with prevalence ranging from ~10% to 50% depending on the geographical area. Human infection is usually asymptomatic in immunocompetent individuals and may remain for life, but in immunocompromised persons, the infection might be fatal [2].
