Removal of Highly Doped Silicon for Backside Fault Isolation with Fluorine-Based Etches
Authors: Distelhurst Kevin , Densmore Jim , Tang Jiaqi
Published: October 2024

III-V power electronic devices are a growing industry as electric vehicles (EVs), power-demanding servers, and other high-power electronics become more prominent. The design of these devices can alter a failure analysis lab’s process flow typically used on traditional silicon-based logic devices. One such obstacle is backside fault isolation (FI) through highly doped silicon wafers used in GaN-on-Si technologies. Backside fault isolation is critical for many electrical failure analyses so finding several approaches to enable this technique that fits current FA flows is desirable. Chemical and Focused Ion Beam (FIB) based approaches have been used to enable backside FI [1], [2]. This paper considers a plasma-based approach with two separate machines, a Microwave Induced Plasma spot etcher and a chamber based Reactive Ion Etch (RIE). Both utilize a Fluorine-based chemistry which is highly selective to the silicon vs the underlying GaN. The etches are used to selective remove the silicon to form a window to the underlying GaN material. Subsequent backside FI analyses are successfully followed by several other analyses.

Integration of Artificial Intelligence in Islamic Higher Education: Comparative Responses between Indonesia and Thailand
Authors: Syukur Fatah , Maghfurin Ahmad , Marhamah Uswatun , Phaosan Jehwae
Published: October 2024

This study aims to compare the responses of Islamic Universities in Indonesia and Thailand to the adoption of artificial intelligence (AI) in Islamic education learning. This comparative qualitative research collected data from in-depth interviews, participatory observation, and analysis of relevant documents at UIN Walisongo Semarang (Indonesia) and Darul Maarif Islamic College Patani (Thailand). The collected data were analyzed thematically using triangulation, member checking, and audit trail validation models. The findings of this study show similarities and differences; both institutions have not specifically incorporated AI into the formal curriculum as a course, only integrating it implicitly in the hidden curriculum such as research, workshops, and seminars. Indonesian Islamic universities view AI as an important tool for modernizing Islamic education, especially in distance learning and the digitalization of Qur'anic teaching. In contrast, although AI is not explicitly banned in Thailand, there are concerns about its impact on the role of traditional teachers and Islamic cultural values. Regarding ethics, Indonesian students are less likely to consider the potential bias of AI towards Islamic religious information. In contrast, Thai students are more wary of the impact of technology on their religious values. Mastery of AI technology also showed significant differences, with Indonesian students being more advanced.
espantalho e o cientista
Authors: Silveira Lia Carneiro
Published: October 2024

a psicanálise, desde que foi inventada por Freud, é alvo constante de ataques. O mais recente deles veio no recém-lançado “Que Bobagem! Pseudociência e outros absurdos que não merecem ser levados a sério” de Nathalia Pasternak & Carlo Orsi, que requentam a velha acusação de que a psicanálise seria uma “pseudociência”. Ao mesmo tempo, estreia nos cinemas o filme do diretor, roteirista e produtor britânico Christopher Nolan que explora a vida do cientista Oppenheimer. O encontro temporal desses dois produtos da civilização atual nos dá uma excelente oportunidade de cotejar o saber em jogo na ciência e o saber da psicanálise, traçando suas aproximações e diferenças, para explorar um produto que a ciência refuga, mas que a psicanálise recolhe como destinatário de sua operação: a angústia do sujeito.
“O diabo” mulher
Authors: Gondim Leticia , Messias Gontijo Cleyre
Published: October 2024

Este artigo tem por objetivo apontar que, antes de Freud, houve todo um contexto histórico de tentativa de dominação e adestramento do feminino. Freud começou sua clínica escutando as mulheres que apresentavam sintomas que a medicina não conseguia curar, sendo o sintoma histérico uma forma de manifestação desse cerceamento. Embora Freud tenha escutado as mulheres e, a partir disso, alcançado o fator sexual na histeria, ele sintetiza as diferenças sexuais por meio do complexo de castração, limitando-as a uma identificação ideal no par heterossexual e na maternidade. Lacan afirma que não é do pênis que se trata, e, sim, do falo, como um significante que tem lugar no discurso do Outro. A mulher está sob o efeito da primazia do falo, no sentido simbólico que determina a diferença entre os sexos e suas relações, mas, para além da lógica da castração, há uma parte no campo do gozo que pertence ao real. Como o falo está recalcado, existe um desejo inconsciente que diz sobre o saber do sujeito feminino, enquanto a verdade é que a mulher não existe.
Hamlet entre saber e verdade
Authors: GUATIMOSIM BARBARA
Published: October 2024

A partir das sete lições de Lacan sobre Hamlet no Seminário 6: o desejo e sua interpretação e de suas elaborações a respeito da questão que levanta o personagem shakespeariano ao longo de seu ensino, a proposta é acompanhar a investigação de Lacan sobre o impasse dramático que acomete Hamlet, nomeado por Lacan “a tragédia do desejo”, que torna a ação, o ato impossíveis. Lacan tecerá um contraponto entre a tragédia de Édipo rei e a do príncipe da Dinamarca. Se a primeira é marcada pelo parricídio na ignorância de seu ato, Hamlet desde o início de sua saga sabe do assassinato de seu pai e do que precisa fazer. Mas nem a vingança ordenada pelo espectro paterno, nem o amor de uma mulher, Ofélia, o fazem agir. O saber não vetoriza o ato estancado pela angústia de uma verdade que o detém. Quais são os elementos gozosos que enredam Hamlet no espaço “entre”, fazendo com que sua ação desejante só possa coincidir com a própria morte? À luz do descrédito melancólico no qual sucumbe Hamlet, uma pergunta: que saber, que verdade, podem fazem o desejo passar ao ato?

Authors: Zotikov V. I. , Zubareva K. Iu.
Published: October 2024

We studied the effect of microbiological preparations on increasing the yield of soybeans of different varieties. The work was carried out in the conditions of the Oryol region in 2019–2023. Objects of research: soybean varieties Leader 1, Mezenka, Orleya, Osmon, Zusha, as well as Biostim Start preparations, Rizoform Soya, Organit Р, Organit N, Pseudobacterin 3, Biodux, used in pre-sowing seed treatment and foliar feeding of soybean plants in phases 1…3 of trifoliate leaves and budding. The highest increase in soybean yield (6.0 %) compared to the control is provided by inoculation of seeds of the Zusha variety with Rizoform Soya in combination with Biostim Start. Pre-sowing seed treatment in combination with foliar fertilizing with preparations Organit Р, Organit N, Pseudobacterin 3, Biodux in the presence of native races of rhizobacteria in the soil contributed to the introduction of microorganisms included in their composition into the rhizosphere community of plants with subsequent participation in the activation of nitrogen nutrition processes of the latter. On average, for varieties, the number and weight of nodules in the variant with pre-sowing treatment and 2 foliar applications increased by 57.6 and 65 %, respectively, compared to the control, nitrogenase activity – by 67.3 %. The use of a combination of the preparations Organit Р, Organit N, Pseudobacterin 3 and Biodux by pre-sowing seed treatment and one foliar feeding in the phase 1…3 of trifoliate leaves provided the greatest increase in the yield of the Leader 1 variety 0.29 t/ha, Zusha – 0.35, Mezenka – 0 .40 t/ha. The maximum increase in protein content in grain was observed in the Mezenka variety in the variant with pre-sowing seed treatment and 1 or 2 foliar fertilizers – by 1.1 and 1.0 %, respectively.

The aim of the research is a comparative analysis of the response to soil stressors according to the biochemical and productive characteristics of the initial genotypes of oats (line 2h15) and regenerative forms (RA, RAAl, RAMn, RACd) in the framework of evaluating the effectiveness of applied cell selection schemes. In the vegetation experiment, the effect of soil stressors on plants was studied – increased acidity (pH = 4.3), toxicity of manganese ions (65.2 mg/kg, pH = 5.2) and cadmium (2.87 mg/kg, pH = 5.2). The Arkhan variety was used as a standard. The control was soil with a neutral pH (7.2). Regenerants were previously obtained in vitro on artificial media without stress (RA) and with selective agents: alumina acid (RAAl), increased Mn2+ (RAMn) and Cd2+ (RACd). On soil with stressors, the pigment content in regenerant leaves exceeded the baseline values by 1.4…1.6 times. In control, the differences between RA and the baseline are unreliable. All regenerative lines, regardless of growing conditions, were characterized by significantly lower levels of polyphenols in grain (11.2…12.4 mg/g dry weight), compared with the baseline and the standard by 1.2…1.3 times. On backgrounds with artificial addition of metals, an excess of the manganese level in the grain was noted: 1.7 times in RAMn (256.1 mg/kg), compared with the baseline, and there were no differences between them in the cadmium content in RACd (1.82…1.67 mg/kg). On the control background, RA and the baseline significantly lagged behind the standard in terms of grain weight from the plant: in regenerants – 1.29 g; baseline – 1.38 g; standard – 1.65 g. With increased acidity and cadmium, all genotypes decreased productivity relative to the control, but to a lesser extent regenerants (1.6 and 1.4 times, respectively), the baseline – 2.8 and 2 times, the standard – 2.4 and 1.9 times.

Photosynthetic abilities and essential oil content of hydroponic and soil Thuja occidentalis
Authors: Hakobjanyan Anahit , Karapetya Astghik , Ghahramanyan Aristakes , Yeghiazaryan Anna , Gasparyan Armen , Mayrapetyan Khachatur
Published: October 2024

Background: Thuja occidentalis is used in folk medicine to treat several diseases, like bronchial catarrh, and rheumatism. It exhibits antimicrobial properties, and many people today incorporate Thuja occidentalis leaves into herbal tea blends for their healing potential. Brewing tea involves extracting chlorophylls, carotenoids, and essential oils from the plant, which may enhance the tea's therapeutic benefits.
Objective: The aim of the study was to estimate the content of chlorophyll a and b, carotenoids, and essential oils in the leaves of Thuja occidentalis grown in Ararat Valley under hydroponic and soil conditions and compare the herbal properties of this plant depending on the growth conditions.
Methods: Plants of Thuja occidentalis were grown under soil and hydroponic conditions. The hydroponic substrates used red and black slags. Hydroponic plants were nourished with the nutrition solution offered by G. Davtyan. The content of chlorophyll a and b, and carotenoids were estimated spectrophotometrically in an alcohol solution of leaves. The essential oil of plant leaves was extracted by hydrodistillation.
Results: In our study, the content of chlorophyll a and b and carotenoids increased in all studied plants from May to July. The highest content of them was recorded in soil plants (chlorophyll a – 7.2-8.8 μg/ml, chlorophyll b – 2.5-3.2 μg/ml and carotenoids – 1.8-2.2 μg/ml). Plants grown in red slag showed slightly higher levels of these components compared with plants grown in black slag, especially in May. The content of essential oil was higher in hydroponic plants (0.5-0.52%), compared with the soil plants (0.3%).
Conclusion: Our study showed that the content of chlorophyll a and b and carotenoids in leaves of Thuja occidentalis changes depending on the studied month and soil plants are inferior to the hydroponic plants in essential oil content. All this supports the idea that the healing abilities and properties of Thuja occidentalis leave depend on the harvesting time and growth condition.

Chunking in the Second Language: Implications for Language Learning and Teaching
Authors: Y. Wang Serene , H. Christiansen Morten
Published: October 2024

Among the various challenges that adult and other late language learners face on their journey to achieving nativelike proficiency, chunking has been identified as one of the most difficult tasks to master. Language users are able to derive and utilize chunks during language processing—both in the first (L1) and the second language (L2)—yet the extent to which the L2 learners utilize and benefit from chunking is not on a par with L1 speakers. L2 learners are generally less sensitive to the statistical regularities in the linguistic input and possess a smaller repertoire of multiword expressions, leaving them susceptible to slower real-time language processing, hampered comprehension during conversation, and distinct production errors. Drawing on insights from Brian MacWhinney's Unified Competition Model of L1 and L2 acquisition, this review examines these unique challenges in L2 chunking as a function of differences between L1 and L2 learning. According to the Unified Competition Model, the existence of deeply entrenched L1 linguistic representations may hinder effective L2 chunking by encouraging over-segmentation in favor of L1 transference at the lexical level and diverting the necessary attention away from the grammatical elements in prefabricated multiword units. Based on these observations, we offer practical suggestions for educators to facilitate chunking in L2 learners and bring them closer to nativelike fluency.
„1989“ als Mythos – Apokalypse als Neuanfang. Eine tiefenhermeneutische Fallanalyse der apokalyptischen Narrative und der Wendebezüge auf den Corona-Protesten
Authors: Kalkstein Fiona , Dilling Marius
Published: October 2024

Der Beitrag widmet sich der Frage, welche psychosoziale Rolle die Bezüge zu „1989“, die damit verwobenen apokalyptischen Narrative und Verschwörungsideen auf den Corona- und den nachfolgenden Protesten spielen. Grundlage bildet eine tiefenhermeneutische Fallanalyse. Es zeigt sich, dass die kollektiven Narrative auf den ostsächsischen Protesten einerseits ermöglichen, Aggression kompromisshaft auszuagieren und andererseits dazu beitragen, Ohnmacht, Schwäche und Schuldgefühle abzuwehren. Dass das ideologische Angebot, die Ereignisse um den Gesellschaftszusammenbruch wieder dauerhaft in die Gegenwart zu holen, auf derart fruchtbaren Boden stößt, wird mit der jüngeren deutschdeutschen Geschichte als ambivalenten Erfahrungsraum in Verbindung gebracht. Während über das Geschehen gesprochen werden kann, ist die emotionale Relevanz sowohl gesellschaftlich als auch individuell unzureichend verarbeitet.
Which Attributes Explain Gender Differences in Impostor Syndrome Scores in Medicine and Health Sciences Students: A Secondary Multivariate Analysis
Authors: Kozinc Žiga , Klen Katarina Kolenc , Zupančič Manca Opara
Published: October 2024

Impostor Syndrome (IS) is a psychological pattern where individuals doubt their accomplishments and fear being exposed as frauds, despite evidence of success. This study investigates gender differences in IS among 753 medical and health sciences students and graduates, using the Clance Impostor Phenomenon Scale. We aim to discern item-specific gender disparities in IS manifestations and develop a canonical variable that encapsulates these differences. Our findings reveal significant disparities: women display higher scores related to self-doubt and fear of failure, while specific IS aspects in men are associated with overcompensation. These insights suggest the need for gender-specific educational and clinical strategies to address IS in medicine and health sciences. By employing a multivariate analysis of variance, this study refines our understanding of how IS differently affects genders, aiding in the design of targeted interventions that can enhance well-being and professional efficacy among future healthcare professionals. Such strategies are crucial, emphasizing the importance of creating supportive environments to foster resilience in these high-stakes fields.

A preliminary study of Missouri's domiciliary homes and boarding homes for the elderly : four case studies
Authors:   , Heichel Paula A.
Published: October 2024

We call them the "golden years", ages 65 and over. Yet for many of the 20 million elder Americans these later years of life are not exactly "golden." Not all of our nation's 20 million elderly are enjoying their retirement years in sunny Florida, or California; quite the contrary, a vast number do not have pensions or investments that would enable them to relocate and live a pleasant life of leisure. Many have few or no living relatives to turn to as they grow older and have an increasing need for financial or emotional support. Unfortunately for the less well-off their waning years may be years of hardship and despair because they have no one to look to for assistance and often have severely limited financial means. But what could be seen as most distressing in this matter is the fact that our aged population grows daily, showing every sign of further enlargement in the future. Since the turn of the century advancements in science and technology have given us more and better food, improved sanitation, substantial housing, and improvements for some in working conditions; but advancements in the fields of medicine have provided us with even more. Drastic cuts in infant mortality and the near elimination of contagious diseases in childhood and early adulthood have contributed to people surviving so as to be counted among the fast growing population of elderly citizens.
Live animal performance and carcass characteristics of bulls versus steers
Authors:   , Landon Mark E.
Published: October 2024

"Consumers, increasingly, are expressing a preference for beef cuts with a high proportion of lean in relation to fat. The continued increase in consumption of beef of the Choice and Good grades suggests a preference for beef with desirable eating qualities. The production of quality lean beef is a goal that involves many aspects of animal production including breeding, feeding and management. The trend toward leaner beef carcasses and more efficient feedlot performance has focused atterition on the effect of age at the time of castration on feedlot efficiency and carcass meatiness and quality. Since the early 1950's, several reports have suggested that young bulls gain faster and more efficiently than comparable steers and that the bullock carcasses yield a greater percentage of retail cuts. Reports also indicated that the meat from young bulls was similar in palatability to meat from steers of similar age and breeding. The objectives of this study were to compare the feedlot performance, qualitative and quantitative carcass characteristics of beef produced from Hereford bulls, crossbred bulls, Hereford steers castrated at 205 days, crossbred steers castrated at 205 days, and crossbred steers castrated at birth."--Introduction.
Chronology of pair formation and breeding biology in the wood duck
Authors:   , Scherpelz Judith A.
Published: October 2024

The annual behavioral cycle of the wood duck (Aix sponsa) has not been thoroughly investigated in the wild. An increase in the numbers of pairs throughout the fall indicates courtship activity may begin soon after completion of the prealternate molt. The timing of pair formation and the relationship of the breeding strategy to habitat are important in understanding the ecology of the wood duck. A study of courtship behavior and pair formation chronology can give insight to behavioral responses to an environment.This study was designed to acquire information on pair formation and behavioral responses to environmental cues by pursuing the following objectives: 1. To determine chronology of pair formation by observation of courtship behavior throughout the year in the wild. 2. To determine strength of the pair bond in fall and spring including: a. definition of a pair b. interactions between pairs and groups of wood ducks c. change in behavior patterns through the courtship period. 3. To determine existence or function of unpaired males in spring. 4. To determine habitat use.
^14C-DDT dynamics in a cold water model food chain
Authors:   , Nevins Michael J.
Published: October 2024

The uptake, elimination, and metabolism of ^14C-DDT in a maple leaf-scud-rainbow trout food chain was investigated using gas chromatography, liquid scintillation, and thin-layer chromatography-autoradiography. In this modular food chain, both scud and rainbow trout accumulated more DDT from the water than from food. After adjusting for growth in the trout, scud and trout showed little elimination of residue after exposure ceased. DDT was metabolized to DDE by both organisms. The results of this study will be a baseline for comparison of the dynamics of other compounds in this model.
A proposed set of alternative end-products for an electronic data processing farm accounting and managerial information system
Authors:   , Lovell Ashley C.
Published: October 2024

"Objectives and methodology: The dual objectives of this thesis are to: 1. Present those concepts and principles useful in developing an EDP farm accounting and managerial information system as suggested by an in-depth review of economics, managerial economics, managerial accounting and farm accounting. 2. Present a comprehensive set of end-products for an EDP farm accounting and managerial information system resulting from an integration of the concepts provided by the four fields reviewed. This group of end-products should more fully utilize existing computer technology and. better fulfill the managerial information needs of modern farm managers. The in-depth review of economics, managerial economics, managerial accounting and farm accounting revealed that the four fields of knowledge are similar in purpose for they are all concerned with aiding the firm in maximizing profits. Although no distinct lines of demarcation exist between the four fields-- especially between economics and managerial economics, and managerial economics and managerial accounting--the methods provided by the various disciplines to the firm in achieving its goal of profit maximization diverge. The two general areas of economics and accounting are closely related although this subtle interrelationship is often belittled. In general, much of the statistical data utilized by economists originates from accounting systems; reciprocally, proper interpretation of accounting data by accountants requires consideration of the economic concepts involved. Thus, the interrelationship of economics and accounting is of this general nature. Fundamental improvements in farm accounting theory are advocated as a result of the intensive review of the several distinct fields of knowledge-- economics, managerial economics, managerial accounting, and farm accounting. The diversity of methods and pseudo-independence of the four fields suggests the need for effectively integrating the relevant concepts provided by each into a comprehensive group of end-products for an EDP farm accounting and managerial information system."--Page 11.
Integration hochschulischer Bildung in die berufliche Weiterbildung

Published: October 2024

Aktuelle Entwicklungen im pflegerischen Bildungssystem betreffen nicht nur das neue Ausbildungssystem, sondern stellen auch veränderte Anforderungen an Weiterbildungen. Die Hochschule Osnabrück und das Niels Stensen Bildungszentrum kooperieren im Rahmen der Weiterbildung zur „Fachkraft für Leitungsaufgaben in der Pflege“ sowie der Weiterbildung zur Praxisanleiterin/zum Praxisanleiter, um die Durchlässigkeit zwischen den Bildungssektoren zu stärken. Den Teilnehmenden soll sowohl eine Qualifikation der beruflichen Weiterbildung als auch eine hochschulisch verankerte Kompetenzentwicklung ermöglicht werden. Nach Abschluss der Weiterbildungen wurden die ehemaligen Teilnehmenden mittels eines selbst entwickelten Fragebogens befragt. Der Rücklauf beträgt 43,1% (entspricht 58 Personen). Die ehemaligen Teilnehmenden befürworten mehrheitlich (88%) die Integration von Hochschulmodulen in pflegerische Weiterbildungen. Gleichzeitig ergibt sich ein differenziertes Bild: Befürchtungen einer Überqualifizierung und Praxisferne treffen auf die Hoffnung einer Professionalisierung der Pflege und eines Austauschs auf Augenhöhe mit anderen Professionen. Um eine hochschulisch verankerte Kompetenzentwicklung zu fördern und die Bildungsdurchlässigkeit in der Pflege zu stärken, müssen die Bildungsangebote zukünftig stärker an die Bedürfnisse der beruflich Pflegenden im Rückgriff auf bewährte Bildungsstrukturen angepasst werden.

Con su inconfundible aleteo entre las flores y sus brillantes colores iridiscentes, podemos observar colibríes casi en cualquier lado, ya sea en zonas forestales, áreas de cultivo o en el jardín de nuestras casas. Sin embargo, pocos saben que el viaje de algunas especies pudo haber empezado a más de 5,000 kilómetros al norte, y que sólo están aquí a pasar el invierno. La presente guía es la culminación de más de 30 años de monitoreo, realizados en la Reserva de la Biósfera Sierra de Manantlán, estudiando la comunidad de aves terrestres, particularmente las poblaciones de colibríes. Como resultado tenemos una lista de 24 especies de colibríes, migratorias y residentes al Centro Occidente de México, con información acerca de sus estrategias migratorias, distribución altitudinal, uso de hábitat y respuesta a los ambientes post incendio. Con esto, buscamos sentar las bases de conocimiento para implementar medidas de manejo en favor de la conservación de la comunidad de colibríes. Esta guía está dirigida a todos los curiosos observadores de la naturaleza que deseen conocer más acerca de la rica comunidad de aves que habitan en el centro Occidente de México.

Bu çalışmada fen bilimleri ve sosyal bilgiler öğretmenlerinin çevre bilinci ve alt boyutlarına ilişkin algıları ve bu algılarının demografik değişkenlere göre durumu araştırılmıştır. Araştırma betimsel tarama modelindedir. Araştırmanın verileri Denizli ili merkez ilçelerindeki resmi okullarda görev yapan 104 fen bilimleri ve 80 sosyal bilgiler öğretmeninden elde edilmiştir. Veri toplama aracı olarak Çevre Bilincine Sahip Öğretmen Nitelikleri Ölçeği kullanılmıştır. Araştırma sonucunda fen bilimleri ve sosyal bilgiler öğretmenlerinin çevre bilinci alt boyutlarına yönelik algılarında en yüksek ortalamanın tutum ve bilinçlendirme boyutunda olduğu görülürken bunu uygulama ve model olma boyutu ile sosyal aktivite ve iş birliği boyutu izlemiştir. En düşük ortalamanın ise günlük yaşamla ilişkilendirme boyutunda olduğu tespit edilmiştir. Genel çevre bilinci algısının ise genellikle düzeyinde olduğu ortaya çıkmıştır. Fen bilimleri ve sosyal bilgiler öğretmenlerinin çevre bilinci algıları öğretmenlerin demografik özelliklerine göre incelendiğinde ise cinsiyet, yaş ve öğrenim düzeyine göre farklılık göstermezken branş ve çevre eğitimiyle ilgili eğitim almaya göre farklılık göstermiştir. Bu farklılıkların branşa göre günlük yaşamla ilişkilendirme boyutunda fen bilimleri öğretmenleri lehine yüksek olduğu görülmüştür. Çevre eğitimiyle ilgili eğitim almaya göre ise bütün boyutlarda ve genel olarak çevre eğitimi konusunda eğitim alanların bu konuda eğitim almayanlardan daha yüksek düzeyde çevre bilincine sahip oldukları görülmüştür.
NATURALEZA DE LA NULIDAD DE LAS CLÁUSULAS O ESTIPULACIONES ABUSIVAS EN CONTRATOS CELEBRADOS CON CONSUMIDORES O MICRO O PEQUEÑOS EMPRESARIOS. SOBRE LA CONSISTENCIA Y FUNCIONALIDAD DEL RÉGIMEN DE NULIDAD ABSOLUTA CONTEMPLADO EN EL CÓDIGO CIVIL
Authors: Campos Micin Sebastián Nicolás
Published: October 2024

Luego de una exposición sintética de las dos principales tesis acerca de la naturaleza de la nulidad contemplada en la Ley n.° 19496 respecto de las cláusulas o estipulaciones abusivas, se examina si el régimen de nulidad absoluta exhibe las disfuncionalidades acusadas por parte de la doctrina. Se intenta mostrar que todas las objeciones a la consistencia y a la funcionalidad de la aplicación de dicho régimen son derrotables y que no justifican la construcción, por vía interpretativa, de un régimen especial. Se postula que el régimen de nulidad absoluta, rectamente entendido, no solo es funcional, sino que, además, es más protector que un pretendido, incompleto e incierto régimen especial.
INSTRUCCIONES NOTARIALES Y EL PAPEL DEL NOTARIO EN EL PAGO DEL PRECIO DE LA COMPRAVENTA
Authors: Rodríguez Javier
Published: October 2024

Una reciente sentencia de la Corte Suprema ofrece valiosas directrices en relación con el modo en que los notarios deben cumplir con las instrucciones que les imparten las partes de la compraventa para efectos de pagar el precio. El fallo hace especial énfasis en la falta de discrecionalidad del notario para determinar el alcance de las instrucciones, así como en su imposibilidad de intervenir en la distribución de riesgos libremente acordada por las partes. La Corte Suprema profundiza, asimismo, en la naturaleza jurídica de las instrucciones, haciéndoles aplicable las reglas del mandato. El comentario analiza críticamente estas materias a la luz de los objetivos prácticos que las instrucciones están llamadas a cumplir.
La vil·la de la Gran Via‑Can Ferrerons (Premià de Mar, Barcelona) durant l’Antiguitat Tardana

Durant el segle V dC la vil·la de la Gran Via‑Can Ferrerons sembla presentar una fase de gran prosperitat. Tot i que el nostre coneixement és parcial, a causa d’un incontrolat urbanisme entre les dècades de 1960 a 1980, d’una banda, constatem que un espai productiu amb dipòsits és transformat en pars urbana, amb un magnífic mosaic; en un altre punt, es va aixecar ex novo un espectacular edifici de planta octogonal de m.s de 700 m2, usat com a pavelló de recepció i on presumiblement es practicà l’otium per part d’algun membre destacat de la classe benestant (potentiores) de Barcino. Aquesta situació de prosperitat contrasta amb la dels establiments de l’ager de Baetulo i d’Iluro, en el millor dels casos reconvertits en espais productius si no abandonats.

Published: October 2024

Existing Mechanical Insufflation-Exsufflation (MI-E) devices often overlook the impact of cough airflow pressure on mucus clearance, particularly lacking in control over airway pressure during the expiratory phase, which can lead to airway collapse and other types of airway damage. This study optimizes the design of cough assist system and explores the effectiveness of PID and adaptive control methods in regulating airway pressure. The adaptive control method compensates for hose pressure drop by online estimation of the ventilatory hose characteristics. It achieves precise tracking of target pressure and ensures the generation of peak flow rates effective for mucus clearance, even in the absence of known patient lung physiological states and unknown hose leakage parameters. Through a series of comparative experiments, this paper confirms the significant advantages of adaptive control in reducing oscillations and overshoot, capable of more stable and precise airway pressure adjustments. This improved control strategy not only enhances clinical safety but also significantly improves therapeutic outcomes and reduces the risk of complications. The findings indicate that the revamped cough assist system, employing an adaptive control strategy, can effectively prevent airway damage during assisted coughing, offering a safer and more effective sputum clearance solution for critically ill patients with expectoration disorders.

Introduction

Efficient and cost-effective immobilization methods are crucial for advancing the utilization of enzymes in industrial biocatalysis. To this end, in vivo immobilization methods relying on the completely biological production of immobilizates represent an interesting alternative to conventional carrier-based immobilization methods. This study aimed to introduce a novel immobilization strategy using in vivo-produced magnetic protein aggregates (MPAs).

Methods

MPA production was achieved by expressing gene fusions of the yellow fluorescent protein variant citrine and ferritin variants, including a magnetically enhanced Escherichia coli ferritin mutant. Cellular production of the gene fusions allows supramolecular assembly of the fusion proteins in vivo, driven by citrine-dependent dimerization of ferritin cages. Magnetic properties were confirmed using neodymium magnets. A bait/prey strategy was used to attach alcohol dehydrogenase (ADH) to the MPAs, creating catalytically active MPAs (CatMPAs). These CatMPAs were purified via magnetic columns or centrifugation.

Results

The fusion of the mutant E. coli ferritin to citrine yielded fluorescent, insoluble protein aggregates, which are released upon cell lysis and coalesce into MPAs. MPAs display magnetic properties, as verified by their attraction to neodymium magnets. We further show that these fully in vivo-produced protein aggregates can be magnetically purified without ex vivo iron loading. Using a bait/prey strategy, MPAs were functionalized by attaching alcohol dehydrogenase post-translationally, creating catalytically active magnetic protein aggregates (CatMPAs). These CatMPAs were easily purified from crude extracts via centrifugation or magnetic columns and showed enhanced stability.

Discussion

This study presents a modular strategy for the in vivo production of MPAs as scaffold for enzyme immobilization. The approach eliminates the need for traditional, expensive carriers and simplifies the purification process by leveraging the insoluble nature and the magnetic properties of the aggregates, opening up the potential for novel, streamlined applications in biocatalysis.

The voluntary carbon market offers a flexible and cost-effective way to reduce greenhouse gas emissions, which has led to increased interest in these markets. Within the decentralized finance ecosystem, Decentralized Autonomous Organizations leverage the tokenization of carbon credits to enhance efficiency and transparency. KlimaDAO, established in August 2021, aims to accelerate the adoption of carbon markets by integrating blockchain technology to facilitate transparent, secure, and accessible carbon trading. This study analyzes the evolution of KlimaDAO by evaluating its market capitalization, token prices, staking participation, carbon credit retirements, market participation, and concentration. The analysis reveals that while KlimaDAO initially achieved significant engagement and activity, it now faces challenges associated with market maturity and participant retention. Finally, the study highlights the importance of standardization and regulatory frameworks to enhance interoperability, transparency, and legitimacy within the tokenized carbon market.
Mechanosensory entities and functionality of endothelial cells
Authors: Mierke Claudia Tanja
Published: October 2024

The endothelial cells of the blood circulation are exposed to hemodynamic forces, such as cyclic strain, hydrostatic forces, and shear stress caused by the blood fluid’s frictional force. Endothelial cells perceive mechanical forces via mechanosensors and thus elicit physiological reactions such as alterations in vessel width. The mechanosensors considered comprise ion channels, structures linked to the plasma membrane, cytoskeletal spectrin scaffold, mechanoreceptors, and junctional proteins. This review focuses on endothelial mechanosensors and how they alter the vascular functions of endothelial cells. The current state of knowledge on the dysregulation of endothelial mechanosensitivity in disease is briefly presented. The interplay in mechanical perception between endothelial cells and vascular smooth muscle cells is briefly outlined. Finally, future research avenues are highlighted, which are necessary to overcome existing limitations.
