Graphische Programmierung von Industrierobotern
Authors: Chemnitz Moritz , Yordanova Magdalena , Vick Axel
Published: April 2021

Für die Programmierung von Industrierobotern hat jeder Hersteller seine eigene Sprache entwickelt. Zwar stellen alle diese Sprachen einen ähnlichen Funktionsumfang bereit, der Wechsel des Herstellers erfordert aber meist die Neuentwicklung des Programmes. Diese Programmierung ist häufig textbasiert und erfordert einen hohen Einarbeitungsaufwand. In dieser Arbeit stellen wir ein Framework vor, das eine graphische Programmierung ermöglicht und Programme für unterschiedliche Hersteller generiert.**

Authors: Storz Tobias , Schild Leonard , Vogt Marcel , Hofmann Janna , Fleischer Jürgen , Lanza Gisela
Published: April 2021

Trotz der Vielzahl von verschiedensten Anwendungen und Anforderungen an die Batteriezellen werden für viele Produkte standardisierte Zellen eingesetzt. Dabei werden individuelle Anforderungen, insbesondere an den Bauraum, meist nicht beachtet. Unsere Hypothese ist, dass künftige Produkte, vor allem in den Bereichen Unterhaltungselektronik, Power Tools und Elektrofahrzeuge, Batteriezellen benötigen, deren Anforderungen bezüglich elektrischer Eigenschaften und Format angepasst sind. Dies führt zu einer wachsenden Vielfalt an Batteriezellen in Bezug auf Abmessungen, Format und Materialien. Dieser Trend ist bereits bei Batteriezellen für die Unterhaltungselektronik wie Smartwatches und Smartphones erkennbar. Um den unterschiedlichen Kundenanforderungen gerecht zu werden, benötigen die Zellhersteller geeignete flexible Produktionsmaschinen, um hohe Rüstkosten zu vermeiden. Als Lösung wird am KIT eine flexible, automatisierte Produktionsanlage für die Li-Ionen-Pouch-Zellen-Fertigung entwickelt.**

Experimental Investigation on the Mechanism of Piping in Different Two-Stratum Levee Foundations with Weak Spots
Authors: Zhang Li , Wang Chen , Lu Mengmeng , Liang Fayun
Published: April 2021

Earthen levees along rivers may break down because of piping; this is especially the case for levees built on two-stratum levee foundations with an impervious stratum and an underlying pervious substratum. However, the initial stage of this piping is difficult to recognize because finding the piping outlets along the whole levee is challenging. Practical experience confirms that weak spots, such as holes or thickness reductions in the blanket stratum, usually occur at the levee toe. Some of these are harmless, whereas others are not. This study takes weak spots into consideration and provides a detailed description and evaluation of the piping features. Experiments were conducted on three models with different pervious conditions in a flume. Weak spots caused by holes, a thickness reduction, or exposure of the substratum at the levee toe were tested. The results show that the thickness reduction influences the formation of continuous sand boiling once the confined water bursts the blanket stratum. The potential for piping is reduced when the pervious substratum is composed of thin and uniform soil. In the absence of a covering stratum, piping happens with sand boiling. Three typical phenomena, namely sand boiling near the levee toe, a pressure decrease of the confined water, and a rise in the hydraulic gradient in the pervious substratum, could be used as indicators of the occurrence of piping.
Environmental Enrichment Sharpens Sensory Acuity by Enhancing Information Coding in Barrel Cortex and Premotor Cortex

Published: April 2021

Environmental enrichment (EE) is beneficial to sensory functions. Thus, elucidating the neural mechanism underlying improvement of sensory stimulus discrimination is important for developing therapeutic strategies. We aim to advance the understanding of such neural mechanism. We found that tactile enrichment improved tactile stimulus feature discrimination. The neural correlate of such improvement was revealed by analyzing single-cell information coding in both the primary somatosensory cortex and the premotor cortex of awake behaving animals. Our results show that EE enhances the decision-information coding capacity of cells that are tuned to adjacent whiskers, and of premotor cortical cells.
Planting a Native Pollinator Garden Impacts the Ecological Literacy of Undergraduate Students
Authors: Wells Carrie N. , Hatley Melissa , Walsh Jane
Published: April 2021

Ecological illiteracy exists, in part, because students may be technologically advanced but often lack intellectual curiosity about their natural environment. Botanical illiteracy, often referred to as “plant blindness,” results from several interacting factors, including a lack of interest in plants and insufficient exposure to plant science before students reach college. We were interested in understanding how a hands-on activity planting native plant species translates across undergraduate majors in improving botanical literacy, as well as increasing awareness and concern about the loss of plant and pollinator biodiversity worldwide. We conducted a survey of both life-science majors and nonmajors to examine their attitudes toward native plants and pollinators. We also examined the change in attitudes of science majors following a hands-on native garden planting activity. We found that life-science majors generally had a stronger understanding and valuation of native plants and pollinators than nonmajors. We also found that life-science majors demonstrated an increase in their knowledge and valuation of native plants and pollinators after participation in the gardening activity. We suggest that this type of activity is important in alleviating plant blindness and in increasing ecological literacy, even among already knowledgeable science students.
Ease into Climate Change Instruction through Ocean Acidification
Authors: Owens David C. , Rafolt Susanne , Arneson Erin M.
Published: April 2021

Although climate change garners the bulk of headlines, ocean acidification is an equally important issue that also results from our increasing consumption of fossil fuels. As atmospheric CO2 dissolves into the ocean, the ocean’s pH decreases, making it increasingly difficult for organisms that build calcium carbonate skeletons to grow and thrive. Given that these marine calcifiers – such as corals, snails, shellfish, crustaceans, and plankton – often form the base of oceanic food webs and are habitat and food resources for larger oceanic plants and animals (including humans), ocean acidification poses a serious threat. In this article, we present a series of investigations that provide evidence that increases in anthropogenic sources of CO2 contribute to the acidification of the ocean, and that an increasingly acidic ocean can negatively impact marine calcifiers.

Published: April 2021

The study of mammals that hibernate provides a unique avenue for students to explore the concepts of metabolism, bone structure, and the impact of climate change on mammals with evolutionary adaptations to extreme seasonal changes in food supply. “Secrets of the Hibernators” is a student-centered, self-guided kit developed by educators in close collaboration with biologists studying the physiology of hibernating animals. The kit uses a hands-on, inquiry-based approach, providing students access to research data that they can easily analyze and interpret, as well as an experimental model for exploring how temperature can affect metabolism. Students learn how the study of hibernators may provide clues to help find solutions to human diseases such as obesity and osteoporosis.
Audiovisual Communication and Subtitling from the Perspective of Semiotic Cohesion: A Case Study of “Garden of Eden”
Authors: Ulvydienė  Huber Loreta , Lideikytė Viktorija
Published: April 2021

Films as multimodal products have an increasing entertainment value, so the need to transfer them to other cultures arises. Audiovisual translation (AVT) becomes the only practice to translate and adapt multimodal discourse to various audiences. Together with audio description, that translates the visual into spoken language completing in this way the sounds and dialogues of films, subtitling deals with the changes within the semiotic system. Since subtitles have to interact and work in synchrony with dialogue and image, a great variety of problems arises when this translation mode is employed because a lot of constraints that exist. However, semiotic cohesion between subtitles and other elements such as moving pictures, verbal and non-verbal language and camera editing should be retained. The aim of the paper is to analyse the cases of semiotic cohesion in the English subtitles of the Lithuanian film Garden of Eden (2015). The research is carried out within the framework of multimodal discourse analysis that permits the incorporation of all identifiable communicative modes. The course of practical investigation crystallises out into three underlying directions: assessment of semiotic cohesion, identification of particular form(s) of semiotic cohesion depending on its (dis)appearance on screen and the analysis of the selected instances.
Dynamic High-density Functional Substrate Mapping Improves Outcomes in Ischaemic Ventricular Tachycardia Ablation: Sense Protocol Functional Substrate Mapping and Other Functional Mapping Techniques
Authors: Papageorgiou Nikolaos , Srinivasan Neil T
Published: April 2021

Post-infarct-related ventricular tachycardia (VT) occurs due to reentry over surviving fibres within ventricular scar tissue. The mapping and ablation of patients in VT remains a challenge when VT is poorly tolerated and in cases in which VT is non-sustained or not inducible. Conventional substrate mapping techniques are limited by the ambiguity of substrate characterisation methods and the variety of mapping tools, which may record signals differently based on their bipolar spacing and electrode size. Real world data suggest that outcomes from VT ablation remain poor in terms of freedom from recurrent therapy using conventional techniques. Functional substrate mapping techniques, such as single extrastimulus protocol mapping, identify regions of unmasked delayed potentials, which, by nature of their dynamic and functional components, may play a critical role in sustaining VT. These methods may improve substrate mapping of VT, potentially making ablation safer and more reproducible, and thereby improving the outcomes. Further large-scale studies are needed.
Risk Stratification in Arrhythmogenic Right Ventricular Cardiomyopathy
Authors: Wallace Ryan , Calkins Hugh
Published: April 2021

Arrhythmogenic right ventricular cardiomyopathy (ARVC), also called arrhythmogenic right ventricular dysplasia or arrhythmogenic cardiomyopathy, is a genetic disease characterised by progressive myocyte loss with replacement by fibrofatty tissue. This structural change leads to the prominent features of ARVC of ventricular arrhythmia and increased risk for sudden cardiac death (SCD). Emphasis should be placed on determining and stratifying the patient’s risk of ventricular arrhythmia and SCD. ICDs should be used to treat the former and prevent the latter, but ICDs are not benign interventions. ICDs come with their own complications in this overall young population of patients. This article reviews the literature regarding the factors that contribute to the assessment of risk stratification in ARVC patients.

The article presents the examination of three generations of a family with diagnosed left ventricular noncompaction (LVNC) and various phenotypic manifestations of the disease (isolated, hypertrophic and dilated type of LVNC). As a result of a molecular genetics tests, a previously undescribed single nucleotide deletion in the PRDM16 gene was revealed in all family members with the LVNC phenotype, leading to a frameshift mutation in exon 9 and the formation of a premature termination codon. This gene encodes a transcription factor responsible for after-birth suppressing the expression of genes involved in prenatal and postnatal development. Despite the presence of previous studies showing the relationship of the PRDM16 gene with LVNC development, currently there are insufficient data to prove the pathogenicity of the identified variant. However, the segregation of the symptomatic variant in three generations supports the association of the identified variant with LVNC. With the accumulation of information about changes in PRDM16 in patients with cardiomyopathies, it is possible to change the status of this gene and clarify its contribution to primary heart diseases.

Published: April 2021

Takayasu's arteritis is a chronic granulomatous vasculitis of large vessels of unclear etiology, predominantly affecting the aorta and its main branches, with possible involvement of the coronary and pulmonary arteries. The true prevalence of this disease is unknown, but it is extremely low, given the rare diagnosis and the absence of pathognomonic symptoms. In clinical practice, the criteria proposed by the American College of Rheumatology are used for making a diagnosis. A wide range of imaging diagnostic techniques plays a significant role. This article provides a literature review and a case report of Takayasu's arteritis in a patient admitted with an acute coronary syndrome.

Published: April 2021

At the end of the last century and, especially, in the first two decades of the 21st century, a significant technological breakthrough took place in clinical laboratory diagnostics in Russia. The transition from manual techniques to high-tech and high-performance automated systems has changed the potential of laboratory medicine. The laboratory has become a high-tech, rapidly developing branch of medical organizations. Following the changes in technology, the range of diagnostic tests began to alter, while the list of laboratory tests available grew. These dynamics are growing every year. Simple routine techniques, practiced for all patients, are complemented by more specific tests. The place of conventional routine tests has been determined by many years of practical experience, while modern analyzers allow the use of tests with a high evidence value of recommendations, which, in the context of evidence-based medicine, enable the clinician to conduct a personalized diagnostic search. At the same time, in order to use all the possibilities of laboratory medicine, the discipline Clinical Laboratory Diagnostics should be included in educational programs at different stages of a doctor's training.

Authors: Majumdar Anindita , Sarkar Kriti , Ghosh Abhinita
Published: April 2021

COVID-19 pandemic and the lockdown declared due to this, has brought a robust stagnation in different sectors of human life. When the world is facing delayed development and crisis in economic sectors, job markets, work culture, etc., educational realm has also undergone a massive change
within just few months. In this era of new normal, not only the teaching-learning system is forced to be shifted to online platform; but also the students who were supposed to complete their college/ university degrees this year are still in a stagnated state. Along with the present pandemic
environment stress, the uncertainties relating to their future aspirations have become an added burden for these students’ mental health. This study has focused on the present mental health status of these final year students of undergraduate (UG) level (groups separated as higher education
and job aspirants) and the coping styles adopted by them to combat environmental uncertainties in relation to their psychological capital. The study, thus, investigated difference in psychological capital, present mental status and adopted coping style between final year UG students aspiring
for higher studies and job. The data was collected through online platform and after proper screening, and analysed with the help of descriptive and multivariate statistical techniques. Final results observed no particular difference in psychological capital between the two groups of final
year UG students. However, difference was observed in their adopted coping strategies and present mental health status. As the psychological capital shows no difference, the difference observed in mental health condition and coping, hence, could be attributed to the stress and insecurities
culminating from pandemic crisis.
Experiential Learning: Folklore as a Learning Experience
Authors: Menon Pushpa R.
Published: April 2021

New Education policies are designed keeping in mind the increased significance of acquiring 21st century skills. The system of rote-learning and text-based learning that was introduced by the British in India. is being replaced by new pedagogical skills and teaching methodologies. Learning
is now affected through direct or virtual experiences or based on actual hands on activities. This paper intends to study the concept of Experiential Learning as expounded by Kolb. It recommends the various activities that can be used for Experiential Learning. It also throws light on the
various parameters of defining and assessing the outcome of an experience. The paper also briefly traces the history of folklore and discusses the potential of folk stories and other tales from the past as an effective medium in Experiential Learning. Stories have the innate ability to keep
the learner enthralled and ensure active involvement and reflection of the learner. Besides giving opportunities for developing language and other skills, exposure to folklore can also bring in awareness for environmental, social and gender related issues. Use of folklore can help the learners
to weave across continents and culture and to take the experience beyond a classroom.
The acceptance of mLearning amongst the suburban college students: A micro-level study in North 24 Pargana of West Bengla
Authors: Sarkar Indrani
Published: April 2021

The revolution of mobile phones is not merely limited to calling or texting; it has reached almost every sphere of humankind. In this 21st century, studies have claimed that mobile phones' accessibility is comparatively higher than the toilet. Nearly 6 billion people worldwide now are
accessing a working mobile handset (UNESCO, 2014). The ubiquitous use of mobile phones brings mobility to its users and helps them accept this ICT based technology worldwide. This new technology of communication also has a remarkable contribution to the educational sector. Its real-time communication
makes learning effortless and congenial to the potential learners. This study will explore mobile-based learning technology among the higher education aspirants of suburban colleges in North 24parganas of West Bengal. Suburban students are not getting the same facilitates as metro city students.
Besides that, suburban culture and social taboos sometimes make problems to use or access mobile phones by students. However, this will not be focused on the comparison between metro city students and suburban students. Moreover, this study will focus on the usage of mobile phones among suburban
college students and to what extent these students are comfortable with the mobile learning method. M-learning or mobile-based learning is "learning across multiple contexts, through social and content interactions, using personal electronic devices" (M-Learning: Revision History
- Wikipedia, 2020). The benefits of mLearning not only accepted by the students and educational institutions also the Indian higher education departments now have concentrated on this technology for its mass availability, user-friendly access, instantaneous sharing capacity, personalized
uses, and Running connectivity. In the future, the limitations and barriers of learning can be overcome through mLearning technology.

Learner Centred methods of Business English Learning
Authors: Banerjee Debkanya , Roy Ayan
Published: April 2021

This research was started by following the widespread claim regarding the success of ‘learner-centred teaching approach’ across all disciplines throughout the world. It seeks to look at whether such a claim is true by implementing a theoretical framework of learner centred
teaching in an EFL1 Classroom. A qualitative design involving an English teacher of and a number of learners from a vocational2 higher institution were used. The findings of this study overall proved that the implementation of this ‘learner-centred teaching’ framework could make
a difference in students’ learning. Their learning became more meaningful, interesting and democratic3. This ‘Learner Centred Method’ approach emphasizes a spread of various sorts of methods that focuses on what the scholars are learning, it changes the role of the teachers
from a provider of information to facilitating student learning. Traditional teaching often results in students who are passive learners and who don't take responsibility for his or her own learning, this traditional method (“instructor-centred teaching.”) In contrast with, ‘learner
centred teaching’ occurs when instructors specialise in student learning. English is a basic language in all educational institution around the world. People learns the English language in order they can communicate with other people throughout the world. A student who wishes to go abroad
for higher studies he/she should have the basic knowledge in English language just to communicate with the people there and understand what they are trying to express. And in business world English is the basic language for establishing communication between the client and the businessman.
Teaching business English, or other ESP4 classes, usually pays better than teaching "conversation" English classes and some teachers find them more enjoyable. These classes will centre around a work environment and utilize business or ESP vocabulary5. Business English students are
usually quite different from typical school students. They are often older, experienced and tired from an extended day at work and have a particular idea about what they want to learn. Also, sometimes, they're required to require English classes if they need to progress in their company.

Modernism celebrates the inner strength of an individual. In R. K. Narayan's fictional world in the imaginary town of Malgudi, the Indian microcosm is shown to have a bipolar existence where traditional age old beliefs and values are finely blended with modernism of the West. The old
order changes leaving place for the new. The tussle between the "Tradition" and " Modernism " is what gives R. K. Narayan's writings gain a universal appeal.

A ring R satisfies the dual of the isomorphism theorem if R/Ra≅ 1(a) for all elements a of R, where 1(a) denotes the left annihilator. We call these rings left morphic. Examples include all unit regular rings and certain left uniserial local rings. We show that every left morphic
ring is right principally injective, and use this to characterize the left perfect, right and left morphic rings.
NON-CANONICAL TO CANONICAL K-ESSENCE AND ACCELERATED EXPANSION OF THE UNIVERSE
Authors: Mukherjee Somnath
Published: April 2021

The main aim of this paper is to study late time accelerated expansion of the universe with the help of k-essence scalar field. We have chosen non-canonical k-essence lagrangian of the formV(Φ)F(X), and converted to canonical lagrangian with the help of scaling ralation XFX=Ca-3. The obtained lagrangian has two generalised co-ordinate, logarithm of the scale factor (q=lna) and scalar field (Φ). From the obtained lagrangian we studied two most important cosmological parameter, Equation of state parameter (ω≈ –1) and deceleration parameter (q0≈ –1) which are to some extent consistent with the current observations. Both the parameters indicates an accelerated expansion of the universe driven by negative pressure known as dark energy.
NUMERICAL STUDY OF HEAT TRANSFERS IN TISSUES DURING HYPERTHERMIA USING MODIFIED BERNSTEIN POLYNOMIALS
Authors: Srivastava Vineet
Published: April 2021

In the present article, we use modified Bernstein polynomial (B–polynomial) as a basis for the numerical approximation of heat transfer in hyperthermia treatment. A set of continuous polynomials over the spatial domain is use to expand the desired solution using discretization in time variable only. The Galerkin method is use to determine the expansion coefficients to construct initial trial functions. The system of equations has been solved using fourth–order Runge-Kutta method. The accuracy of the solutions is dependent on the size of the B–polynomial basis set. Also, Homotopy Perturbation Method has been applied to solve Matrix form of initial value differential equations which is transformed from boundary value differential equation of desired problem by using central difference scheme. The results thus obtained are in very good agreement with the previous results and it is presented graphically.

Authors: Ahiaba A.A. , Ibrahim M.O. , Ahiaba M.
Published: April 2021

We exploit the dynamics of Lassa fever model with sex structure of the human population with the rat population. The objectives of the research were to: (i) solve for the equilibrium point of the disease free of the model; (ii) obtain basic reproduction number R0 ,
for the model; (iii) investigate local and global stability of the model; and (iv) analyze the sensitivity of parameters of the model. It was found that the disease free equilibrium point was locally asymptotically stable whenever the basic reproduction number ( R0) is less
than one and unstable otherwise. The global stability of the model at disease free equilibrium was found. The analysis of the contribution of each parameter was performed using sensitivity analysis. All positive value parameters are in direct proportionality with the basic reproduction number
Ro and all negative value parameters are inversely proportional to the basic reproduction number. Thus, increase in the values of all parameters with positive sensitivity value would increase Ro. Conversely, increase in the value of all parameters with negative
sensitivity value would decrease Ro

Published: April 2021

In this paper, we present a Highly Pathogenic Avian Influenza model with Saturated Contact rate. We assume that human can only contact HPAI by direct contact with infected birds. A mathematical model consisting of ordinary differential equations has been proposed in order to analyze
/ determine time evolution of susceptible birds and infected birds. Analysis based on the model shows that the population of domestic birds can be made secured against infection by proper vaccination and proper removal of infected birds. During the study the basic reproduction number of the
model was calculated and the following conclusion was made. If R0< 1, disease - free equilibrium is stable, the disease will die out; if however, R0>1, there exists an endemic equilibrium which is stable, Avian Influenza will spread.

Published: April 2021

In this Paper, a staged-progression model for HIV/AIDS transmission dynamics is formulated and analyzed to study the impact of Screening, Condom usage and Condom compliance. The local stability for the disease free equilibrium (DFE) was proved for Rc < 1 and Kransnoselki sublinearity
trick was used to show that the endemic equilibrium (EE) is locally asymptotically stable for a special case whenever Rc > 1. Numerical simulation was also carried out to investigate the effects of screening unaware (unscreened) asymptomatic individuals and Condom compliance. The result
shows the influence of condom compliance and screening on the transmission dynamics of HIV/AIDS. The result clearly shows that increase in the compliance of Condom usage and increase of screening rate of HIV individuals reduces the total number of HIV/AIDS individuals. This point that increase
in Condom usage and screening reduces HIV/AIDS burden.
De G. Politzer et sa critique de l‘inconscient de Freud au a-réalisme de J. Lacan
Authors: Marx Mélinda , Silva Junior Nelson da , Gaspard Jean-Luc
Published: April 2021

En 1928, dans sa « Critique des Fondements de la Psychologie », G. Politzer esquisse les traits d’une psychologie qui vise à réformer la psychologie expérimentale universitaire. S’appuyant sur la théorie des rêves de Freud, Politzer présente une conception de la psychologie tout à fait inédite à son époque. Lacan s’inspirera de ses travaux pour sa thèse sur la paranoïa, participant d’un débat violent au sein du mouvement communiste partagé entre anti-freudisme et freudo-marxisme. En donnant une place essentielle à la parole et au récit, Politzer revendiquait une psychologie concrète. Son refus de la doctrine freudienne, selon lui tributaire de la tradition métaphysique de la psychologie, incluait aussi l’hypothèse de l’inconscient dans une sévère critique du réalisme, inclusion qui ne sera pourtant jamais accepté par Lacan qui s’y opposera avec la prémisse que l’inconscient est structuré comme un langage. Cette orientation allait en toute logique imposer un réalisme de la structure qui s’articule, à son tour, à la faille de la cause empirique.
Trauma e reconhecimento na clínica psicanalítica
Authors: Brum Stephanie
Published: April 2021

O presente artigo objetiva traçar considerações acerca do reconhecimento na clínica psicanalítica. Para tal, traçaremos um contraponto deste com o trauma. Nesse contexto, nos deparamos com o reconhecimento que, por sua vez, se apresenta não apenas como a forma de cuidado promovido por uma adaptação ambiental suficientemente boa, como também enquanto um posicionamento ético assumido na própria clínica. Por outro lado, o traumático surge como uma falha do ambiente em reconhecer as necessidades do indivíduo e mediar sua vulnerabilidade na relação com o meio.
Encapsulating peritoneal sclerosis: from early diagnosis to successful kidney transplantation
Authors: Reis Marina , Gomes Ana Marta , Santos Clara , Lopes Daniela , Fernandes João Carlos
Published: April 2021

Abstract Encapsulating peritoneal sclerosis is an uncommon but serious complication of peritoneal dialysis. In most cases, the symptoms appear after peritoneal dialysis withdrawal, which hampers its diagnosis. We present the case of a 44-years-old Caucasian male who had been on peritoneal dialysis for 6 years and 3 months and was switched to hemodialysis due to ultrafiltration failure. During his last months on peritoneal dialysis, he developed anorexia and asthenia, which were initially attributed to dialysis inadequacy. After hemodialysis induction, the patient developed abdominal pain, increased abdominal volume, obstipation alternating with diarrhea, and weight loss. Computed tomography showed de novo ascites. A diagnosis of early encapsulating peritoneal sclerosis was considered, and treatment was promptly initiated with nutritional support, oral prednisolone, and tamoxifen for one year. The patient progressed with resolution of the symptoms. One month after the end of the treatment, he underwent a successful kidney transplant and remain without any major intercurrences. A high level of clinical suspicion is crucial for the early diagnosis of encapsulating peritoneal sclerosis as the disease can be fatal in advanced stages. This case highlights that with early treatment, kidney transplantation can be successfully performed after an episode of encapsulating peritoneal sclerosis.

Artocarpus bergii (Moraceae), a New Species in the Breadfruit Clade from the Moluccas
Authors: Gardner Elliot M. , Arifiani Deby , Zerega Nyree J.C.
Published: April 2021

Abstract—Artocarpus bergii, named for the late C. C. Berg, is from Halmahera in the Moluccas, and is a close ally of breadfruit (A. altilis). The species resembles the Micronesian A. mariannensis but with generally smaller parts. Because
it is known from only a small area and the type locality is a potential mining site, A. bergii is likely of conservation concern, particularly given its status as a crop wild relative.

Abstract—Rogiera (Guettardeae, Rubiaceae) is a Neotropical genus distributed from Mexico to northern South America that includes shrubs, treelets, or trees, which were previously treated in the taxonomically controversial and confused Rondeletia complex.
Rogiera can be recognized among other Rubiaceae by the combination of multiflowered inflorescences, heterostylous flowers, quincuncial corolla aestivation, a hairy ring at the corolla mouth, and capsular fruits with loculicidal dehiscence. Despite the recent taxonomic circumscription
of Rogiera there is not a comprehensive taxonomic treatment to it. Moreover, regional floristic treatments disagree on the species circumscriptions, with discrepancies in the number of species of Rogiera from 11 to 20. Based on molecular and morphological evidence studied on
field and herbarium specimens, we present a taxonomic revision of Rogiera. We recognize ten species; Mexico is the center of diversity with nine species, four of them endemic. An identification key, descriptions, distribution maps, nomenclatural history, phenological data, and illustrations
of all the species in the genus are provided for the first time. Several names required lecto- or epitypifications designated here.

Abstract—Aspidosperma (Apocynaceae) is composed of trees and shrubs; the genus includes 70 species, 42 of which occur in Brazil. The midwestern region has the second highest diversity, with 30 species, after the northern region, and Mato Grosso do Sul state has
15 species. This study provides macroscopic and microscopic wood features for ten species from A. section Aspidosperma and A. section Pungentia (Apocynaceae) from Mato Grosso do Sul state, Brazil. These characteristics can aid in the identification of Aspidosperma
species because the nine species of these two sections have many morphological similarities; moreover, the wood of these species is economically important for timber production. Through macroscopic and microscopic analysis procedures, the characteristics of the wood and the organoleptic properties
allowed recognition and distinction of the studied taxa. The characters of diagnostic value for recognition of the sections are vessel frequency and arrangement, and ray width. Individually, each species had a set of characteristics that allowed its identification: wood color; vessel arrangement;
vessel length; ray visibility, ray composition and width; presence of crystals, starch grains and lipids in axial and/or ray parenchyma cells. The results may support conscientious exploitation by industries by facilitating the correct identification of the species, and will also help in the
detection of illegal timber logging.

The complex interactions of glomerular and tubular epithelial cells with the basal laminae play a critical role in renal function. Disruption of these interactions has been widely implicated in glomerular diseases and acute renal failure. MDC are a large family of membrane-bound proteins containing metalloprotease, disintegrin (integrin interaction sites), and cysteine-rich domains. Little information is available concerning the presence of MDC in the kidney or their role in renal pathophysiology. Using degenerate PCR primers for the conserved metalloprotease and disintegrin domains of this protein family, cDNA templates from tubules, whole glomeruli, and glomerular epithelial cells (GEC) yielded a single, 195-bp product, which on sequence analysis corresponded to a region in the disintegrin domain of MDC9. Northern analysis of poly(A)+ RNA from tubules, whole glomeruli, and GEC revealed a 3.9-kb transcript, identical to that of mouse MDC9. Using antibodies generated against a 21-amino acid peptide present in the metalloprotease domain of MDC9, Western analysis of concanavalinA-enriched glomerular microsomal extracts demonstrated both processed (76 kD) and unprocessed (116 kD) forms of MDC9, which upon reduction changed to the corresponding 84- and 124-kD forms. Histochemical studies revealed a basolateral localization of intrinsic MDC9 protein in renal cortical tubule cells and glomerular visceral epithelial cells, which colocalized with the β1 integrin chain. Expression of green fluorescence protein MDC9 chimeric constructs in GEC or polarized Madin-Darby canine kidney epithelial cells revealed a similar punctate basolateral surface localization. Transient overexpression of the soluble disintegrin domain-green fluorescence protein chimera in GEC led to dramatic changes in cellular morphology with rounding and detachment from cell monolayers. These studies document the presence of MDC9 in renal epithelial cells and suggest an important role for MDC9 in renal epithelial cellular interactions with the basal lamina and adjoining cells.

Factors driving inpatient and outpatient utilization were studied among patients who began dialysis for chronic renal failure at the New England Medical Center (NEMC) between 1992 and 1997. Clinical, laboratory, and hospital resource utilization data were obtained from patient records and electronic databases. There were 2.2 hospitalizations and 14.8 hospital days per patient year at risk (PYAR). The number of hospitalizations and hospital days per PYAR were higher in the first 3 mo of initiating dialysis (4.3 and 28.3, respectively) compared to after 3 mo (1.9 and 12.9, respectively). Factors associated with increased risk of hospital days within the first 3 mo included non-health maintenance organization insurance, ischemic heart disease, late referral to the nephrologist, and use of temporary vascular access for the first dialysis. Patients with ischemic heart disease and who received dialysis during the years 1992-1994 compared with 1996-1997 had an increased risk of hospital days after 3 mo of initiating dialysis. There were 16.6 outpatient visits per PYAR, with significant differences in utilization between the first 3 mo and after 3 mo of initiating dialysis. Thus, hospital utilization was significantly higher in the first 3 mo compared to after 3 mo, and factors associated with hospital utilization depended on duration of dialysis. In particular, delayed referral to the nephrologist and lack of permanent vascular access were independently associated with increased risk of hospital utilization in the first 3 mo of dialysis. Greater attention to timely referral to the nephrologist and timely placement of vascular access could result in reduced utilization and cost savings.
