Desarrollo de recursos audiovisuales on-line en el Canal Bellas Artes-TV UMU como innovación docente e investigación de nuevos procedimientos artísticos
Authors: García-López Antonio
Published: December 2024

El artículo recoge la experiencia de una acción de innovación docente asociada a la elaboración de recursos audiovisuales para la asignatura “Nuevos materiales, soportes y poéticas pictóricas”, que impartimos en el Máster en Producción y gestión artística de la Universidad de Murcia. Su justificación se debe a la escasez de investigaciones en la que se aborde el uso de nuevos materiales pictóricos adaptados a pautas científicas útiles en la enseñanza universitaria de bellas artes, donde precisamos de una renovada y continua experimentación, de productos nuevos de los que desconocemos su potencial artístico. Esta experiencia nos ha permitido dar visibilidad a investigaciones relevantes realizadas en el seno de la asignatura, donde el material finalmente publicado ha sido revisado por docentes y estudiantes manteniendo una serie de pautas donde confluye la metodología cuantitativa como prueba-error, y aspectos de metodología cualitativa en la que el sujeto participante aporta un nuevo valor simbólico, expresivo y artístico a los materiales. Consideramos que el desarrollo y posterior publicación de material audiovisual como resumen de la sistematización de los ensayos plásticos realizados, hace más eficiente los procesos de enseñanza-aprendizaje. La voluntad de que los contenidos de esas investigaciones se publiquen en abierto en el Canal TV UMU, además de generar motivación y auto-exigencia entre docentes y estudiante, facilita posibles colaboraciones con otros investigadores, así como con fabricantes y distribuidores de nuevos productos artísticos.

Educación secundaria y universidad, una relación truncada
Authors: Huerta Ricard , Domínguez Ricardo
Published: December 2024

El presente artículo plantea la necesidad de acercar las realidades de la educación secundaria y la universitaria, tanto en lo referido a sus planteamientos pedagógicos, como especialmente en lo que atañe a la relación entre el profesorado de ambos eslabones educativos. Se incide en la situación precaria por la que atraviesa la educación en artes visuales, algo que llama la atención si tenemos en cuenta el auge que está tomando la actividad artística en el conjunto de la sociedad. Tanto la normativa legal y su aplicación curricular, así como la falta de atención al colectivo docente, provocan un enorme distanciamiento entre quienes impartimos clase en un entorno o en el otro. En educación secundaria se reduce la presencia de profesorado de Dibujo, debido al poco peso curricular de la especialidad. Por otra parte, los cambios en la contratación del profesorado universitario han determinado una menor presencia de especialistas de Dibujo que venían impartiendo sus clases en el Máster Universitario de Profesorado de Secundaria. Ante tal coyuntura, algunas iniciativas vienen a cubrir el vacío generado. Proyectos de innovación docente como “Second Round”, proyectos I+D como “DECHADOS”, o bien los impulsados por la convocatoria “ACORD”, intentan conectar al profesorado universitario y de secundaria, promoviendo la investigación compartida, y ampliando así las posibilidades que ofrece el entramado institucional. Al unir esfuerzos se reivindica la presencia de la educación artística en el currículum, al tiempo que generamos visibilidad para ambos colectivos.
La reescriptura teatral del «Tirant lo Blanc» per a infants i adolescents de Maria Aurèlia Capmany
Authors: Garcia Raffi Josep-Vicent
Published: December 2024

Breu record de Tirant lo Blanc : Per a ús de col·legials enamorats del teatre forma part de l’inici teatral de Maria Aurèlia Capmany. Va ser la primera adaptació que va fer de la novel·la de Martorell. La va realitzar per als seus alumnes del Col·legi Isabel de Villena en el curs 1958-59. Aquella posada en escena lligada al món escolar va convertir-se en l’inici d’una tasca llarga de reescriptura de l’obra en diferents gèneres. A més, l’adaptació per a infants i joves es completaria després amb una reescriptura teatral per a adults a València en 1971 i amb un nou muntatge posterior de J.A. Codina en el Teatre grec de Barcelona en 1976. Breu record del Tirant lo Blanc fou editat per primera vegada en un recull d’obres de teatre de Capmany en 1968. Posteriorment fou reescrit i editat en 1977 i, finalment, a l’arxiu de Josep A. Codina de l’Institut del Teatre, hi ha altra còpia amb variants textuals. L’obra ha tingut un llarg recorregut: des de l’escenari escolar al teatral professional, de les titelles al teatre d’objectes.
Mirando al Redentor. Caridad, memoria e imagen en las ordenanzas del hospital de la Vera Cruz
Authors: Fernández Fernández Laura , Vírseda Bravo Marta
Published: December 2024

Los estatutos del hospital de la Vera Cruz fundado por Pedro Fernández de Velasco en Medina de Pomar quedaron recogidos en un documento firmado en Valladolid el 14 de agosto de 1455. El conde de Haro dispuso y ordenó tanto el aparato administrativo del complejo hospitalario y su dotación, así como la comunidad que debía gestionarlo y a la que dar servicio. Este documento conocido como el Capitulado, cuenta con una iluminación a plena página que actúa a modo de frontispicio y que contribuye activamente al conocimiento de la fundación hospitalaria, así como a la construcción y proyección de la memoria de su promotor. El presente trabajo se centra en el análisis de la materialidad del Capitulado y en dicha imagen, lo que además nos ha permitido reflexionar sobre aspectos fundamentales que atañen a la gestión del hospital y a su relación con la orden de caballería de la Vera Cruz.

Sapere aude u vrijeme posthumanizma
Authors: Ferenec Kuća Maja
Published: December 2024

U radu se polemizira o humanizmu i posthumanizmu na način da se humanizam ne percipira kao opozicijski pojam posthumanizmu, već kad ishodišni, što će doći do izražaja u argumentu kako je upravo humanizam, a kasnije i prosvjetiteljstvo, osiguralo temelje za kritičko promišljanje posthumanizma. Vodeći se pritom svevremenošću Kantove prosvjetiteljske misli, ovim radom se želi ponuditi afirmativan okvir Kantove moralne filozofije, za koju se nadalje smatra da nudi dobre smjernice za kritičko promišljanje posthumanističkog i transhumanističkog vremena. Takav poduhvat zahtijeva i uvid u ono što posthumanizam uopće jest pa će rad, osim kratkog uvoda, sadržavati tri dijela, a prvi dio će biti posvećen uvodom u posthumanističku misao. Drugi dio rada će sadržavati preliminarnu analizu Kantovog odgovora na pitanje što je prosvjetiteljstvo, a zatim analizu pojmova koji čine srž Kantove moralne filozofije kao što su dostojanstvo, autonomija, volja i sloboda kao smjernice u etičkom razmatranju sve brže rastuće tehnologije. Treći, završni dio afirmirat će Kantovu kritičku moralnu filozofiju i sposobnost prosudbe kao pomoćni alat za prosvjećenost tehnološke invazije, suprotstavljajući se utilitarističkoj etičkoj poziciji.
An approach to choosing protection mechanisms for personal Internet of Things devices based on a mathematical model with two criteria
Authors: Knyazev Maxim Andreevich , Shabrova Anna Sergeevna , Kryuchkov Andrey Andreevich
Published: December 2024

Existing methods to protect Personal Internet of Things (PIoT) devices require continuous updates to counter new threats and vulnerabilities. A major task is developing a universal, efficient approach that accounts for the resource constraints of consumer electronics manufacturers. This study introduces a mathematical model applying criteria for implementation complexity and versatility of protection mechanisms to rank them. The goal is to enhance portable smart device security while controlling costs and complying with information security requirements. The object of the study is the process of securing PIoT devices under current regulatory and technical constraints, as well as limited resources. Its subject is a set of security mechanisms chosen and ranked using a two-criteria model. Within this research, a detailed analysis of recommendations in international and domestic standards was conducted, and feasibility of their adoption was examined through effective resource allocation guided by the model. This research’s novelty lies in an original method for selecting PIoT security mechanisms based on complexity and versatility. By accounting for emerging threats, regulatory mandates, and development expenses, the model provides an integrated strategy that minimizes operational overhead. It delivers comprehensive coverage of security needs despite manufacturers' resource constraints. Findings confirm that adopting this model is a promising, cost-effective way to address PIoT security challenges. By prioritizing complex yet versatile measures, developers can align with legislative requirements and evolving risks. In conclusion, the proposed approach addresses both emergent vulnerabilities and stringent legal obligations, ensuring efficient use of limited resources. By incorporating these criteria, developers can systematically balance complexity, versatility, and cost, achieving stronger protection for consumer IoT products. By emphasizing these factors, it ensures product compliance with evolving standards. The study shows that a two-criteria mathematical model can steer manufacturers toward robust, practical security solutions for Personal Internet of Things devices.
Association of BMI, Waist-hip Ratio and Skinfold Thickness with Sensory Conduction of the Median Nerve in First-year Medical Students: A Cross-sectional Study
Authors: Kamaraddi Seema V , Bhandare Janhavi R , Kour Harpreet
Published: December 2024

Introduction: Nerve Conduction Study (NCS) is a widely used electrodiagnostic tool to evaluate the health of the peripheral nervous system. First-year medical students, due to extensive use of Information and Communications Technology (ICT) and academic pressure, often have limited time for physical activity, potentially influencing nerve conduction. Understanding the influence of anthropometric factors on nerve conduction in this population can help suggest preventive strategies to maintain nerve health.

Aim: To examine the association between various anthropometric variables with median nerve sensory conduction parameters like latency, amplitude, and Nerve Conduction Velocity (NCV) in first-year medical students.

Materials and Methods: A cross-sectional study was conducted in the Department of Physiology at Jawaharlal Nehru Medical College, KLE Academy of Higher Education and Research, Belagavi, Karnataka, India from January 2019 to December 2019. Out of the total population, 110 students were selected through simple random sampling after applying inclusion and exclusion criteria. Anthropometric measurements, including height, weight, Body Mass Index (BMI), Waist-hip Ratio (WHR), and skinfold thickness, were recorded. Median nerve sensory conduction was assessed at the wrist in both hands. Data were analysed using Statistical Packages for Social Sciences (SPSS) software version 20.0, and associations between BMI, WHR, skinfold thickness and nerve conduction parameters were evaluated using Student’s t-test.

Results: For height, no statistically significant differences were found for latency (p=0.15) and amplitude (p=0.65), although shorter individuals had slightly lower NCV compared to those of normal height (p<0.01). BMI categories showed no significant differences in latency, amplitude, or NCV, though underweight individuals had slightly higher NCVs (54.60 m/s) than those of normal weight (51.96 m/s, p=0.54). A WHR ≤0.9 was associated with significantly higher right-hand amplitude (37.63 μV vs. 28.20 μV, p=0.013) and lower left-hand NCV (51.51 m/s vs. 55.02 m/s, p=0.03). Skinfold thickness showed no significant correlation with nerve conduction parameters (p>0.05). These findings suggest that height and WHR may impact specific aspects of nerve conduction, with potential implications for clinical assessments.

Conclusion: This study demonstrates that anthropometric variables, including height, weight, and WHR, significantly influence median nerve sensory conduction parameters. These findings highlight the importance of considering body composition when interpreting Nerve Conduction Studies (NCS), particularly in populations with lifestyle constraints like medical students.
Structures of the ionospheric boundary layer
Authors: Chkhetiani Otto
Published: December 2024

A significant volume of the atmospheric boundary layer is filled with quasi-periodic vortex roller structures, which are well visualized by «cloud streets» forming in the area of upward movements between the rolls. The formation of such structures is associated with hydrodynamic instabilities developing in the atmospheric boundary layer, the development of such instabilities is characteristic of the wind, which has the shape of the so-called Ekman spiral, when the wind velocity vector rotates with altitude. The thickness of the atmospheric boundary layer ranges from 300400 m to 1-2 km. What is going outside of it? It turns out that the Ekman spiral can be encountered again in the altitude range of 70-120 km. At these heights, the environment increasingly resembles a mixture of neutral atoms, molecules and charged particles. In this plasma layer (called in the terminology of atmospheric physics - the transition from the mesosphere to the lower thermosphere, or, in short, the MLT region, and in the ionospheric physics - the region of the lower ionosphere), in the presence of an Ekman spiral, structures similar to those in the atmospheric boundary layer are formed. The presence of such structures explains a number of phenomena that have not previously found reliable justification.

Coats’ White Ring: The Embellished and Spruced up Iron Remnant in the Cornea
Authors: Gonugunta Vishnu Teja
Published: December 2024

Coats’ white ring can be a common finding in the cornea following incomplete removal of the iron rust ring after ocular trauma with iron particles. Though the finding is common and innocuous, it’s etiology is rarely understood and commonly considered as a corneal opacity following an ocular injury and less recognised as a distinct entity. It can be diagnosed from the history and the typical appearance as a ring of discrete white dots in the subepithelial layers with intact epithelium. Patients are asymptomatic and treatment is not required.

Published: December 2024

Purpose:

We report a case of a pseudophakic myopic patient who received placement of an implantable phakic contact lens (IPCL) via a ‘piggyback technique’ resulting in improved visual acuity.

Case report:

A 35year old male patient with both eyes pseudophakic myopia came with complaints of diminution of vision in the right eye more than his left eye. After evaluating all available optical and surgical options, he received off-label placement of a posterior chamber IPCL with a piggyback technique for the pseudophakic right eye with a manifest refraction of -20.0 Ds. Best-corrected distance visual acuity improved from 20/60 to 20/30.

Conclusion:

Our case demonstrates the successful use of an implantable phakic contact lens (IPCL) in a pseudophakic myopic patient by a piggyback technique, resulting in improved visual acuity. This off-label use of IPCL offers a good alternative treatment option for pseudophakic patients with high refractive error.

Published: December 2024

Corneal verticillata presents with whorl like brown deposits in corneal epithelium. They rarely result in reduced vision. The most important potential side effect of anti-tubercular drugs is optic neuritis and can result in corneal verticillate. We report a case of young male with chief complaint of diminution of vision in both eyes undergoing anti-tubercular treatment for pulmonary tuberculosis with corneal verticillata in both eyes. His visual acuity was 3/60 in both eyes with normal fundus findings. This patient had toxic optic neuropathy due to linezolid. Linezolid and clofazimine were discontinued and rapid improvement of visual acuity was seen.

Authors: Nadda Diviyanshu , Sheoran Jyoti , Sachar Saurabh , Narula Anurag
Published: December 2024

CRAO can be considered as an ocular analogue of stroke or an ocular equivalent of acute myocardial infarction. We present a case report of a 32-years-old serving soldier posted at high altitude area with no premorbidities who presented with symptoms of sudden painless loss of vision in the left eye (LE). Best-corrected visual acuity in the LE was PL+ with PR inaccurate. A relative afferent pupillary defect grade IV was observed in the LE. Ocular fundus examination of LE was suggestive of central retinal artery occlusion. Systemic evaluation revealed Steno occlusive disease of bilateral carotids L>R. Haematological investigations revealed increased haemoglobin. Raised haemoglobin due to long stay in high altitude area is tantamount to a sustained inflammatory state that results in endothelial dysfunction by causing hypercoagulable state culminating in small calibre vessel blockage.
Biomicroscopic Lenses to Visualise Posterior Segment
Authors: Chawla Khushboo , Shrivastava Shraddha Raj
Published: December 2024

Ophthalmology is a unique field allowing the clinician a non-invasive ‘window’ to the organ of interest as the eye and especially its posterior segment hide's information, not just about eye-related issues but also about the patient's general well-being.

Although newer technologies like Optical Coherence Tomography (OCT) and other retinal imaging modalities have revolutionised the diagnosis and management of posterior segment pathologies, they are still not a replacement for the easily available, affordable and portable hand-held lenses. By utilising the optics of these lenses, we are able to visualise the remote areas of the eye especially the fundus, in order to facilitate any therapeutic interventions. This article focuses on the various types of lenses used for posterior segment evaluation which are important tools in every ophthalmologists' arsenal.

Published: December 2024

We report a unique case of a 45-year-old female who presented with complaints of diminution of vision, redness, watering, photophobia and foreign body sensation in both eyes along with haemorrhagic crusts involving periocular skin on both sides. She had recently been diagnosed and treated for dengue fever. There was also history of administration of Covid vaccine 1 month back. There was no history of any other chronic systemic illness. Ocular examination showed congestion of conjunctiva, haziness of corneas and diminished corneal sensations in both eyes. Fluorescein stain revealed characteristic dendrites of herpes simplex keratitis in both eyes. Prompt and aggressive treatment for the ocular and skin lesions was started. She responded well to the treatment and recovered completely as observed on subsequent follow ups. Our case highlights the need for physicians or ophthalmologists treating patients with dengue fever to be aware of these complications.

Hernia is a word derived from Latin refering to “bud” or “offshoot.” Acquired hernia can be due to trauma, excessive abdominal distension, frequent over feeding, pregnancy or trauma. The condition is reported to be common in dogs and pigs but less so in other domestic animals. A Balami ram, was presented with a chief complaint of a large bulge on the right side of the abdomen. The client revealed that, the condition was first noticed about 5 months prior to presentation as a small swelling. The ram was said to had been involved in a fight with its pen mate a bull. The patient was aseptically prepared for surgery, drapped and longitudinal skin incision made on each identified bulge, the hernia contents were evaluated and returned into their normal anatomical positions. The peritoneal sheet was then closed and the hernia ring edges refreshed and subsequently apposed using chromic catgut size 2 suture material. An uneventful recovery was achieved. We recommend that, rams should not be housed together with bulls.

Background: Limitations to accessing affordable medications for cancer patients in Nigeria is increasing on a daily basis. Several government interventions have been established to address the affordability of drugs for patients at treatment centers. However, they haven’t been commensurate improvement in patient outcome due to barriers to accessing these medications. This manuscript provides a critical examination of the barriers to affordability of anticancer medications in Nigeria, offering a unique patient-centric perspective that is often underrepresented in healthcare research.
Methodology: The study was a cross-sectional descriptive survey amongst patients that are 18 years and above with Cancers and other tumor diseases in the Oncology unit of the University of Nigeria Teaching Hospital (UNTH) who were willing to participate in the study. Interview based questionnaire distribution was utilized in data collection. 200 questionnaires were distributed, 180 were returned hence giving us (98% response rate) and making our sample size (n= 180). Data gotten was analyzed using descriptive statistics. The IBM statistical package for Social Sciences (SPSS) was utilized.
Results: A total of 180 participants were included in the study, there was an unequal distribution of respondents’ gender (44.4% males and 55.6% females). Only about 36.7% of participants reported to be within the age range of (46- 55 years) which was the most participated age range. More than 60% of the study participants are married. Just about half of the study participants had their monthly incomes between fifty thousand to ninety-nine thousand naira while others earned less.
Conclusion: In this study, barriers to accessing affordable anticancer medications were noted. Government aiding /subsidizing the cost of anticancer medication as well as availability of anti-cancer medicines in government hospitals should be improved.
Assessment of Phytorid Treatment System Efficacy for Irrigation Water Quality in Bindapur, South-West Delhi, India
Authors: Phuloria Poonam , Ranjan Sudarshana , Shah Shachi
Published: December 2024

Constructed wetlands (CWs) offer an eco-friendly approach for treating diverse wastewaters, including sewage and industrial and agricultural effluents. This study evaluates the performance of a self-sustaining constructed wetland system using Phytorid treatment technology for decentralized wastewater treatment at Bindapur, South West Delhi. The government-operated system was monitored for twelve months (2022–2023), with inlet and outlet water samples collected fortnightly and analysed for irrigation water quality parameters. Key irrigation indices, such as Percent Sodium, Sodium Adsorption Ratio (SAR), Residual Sodium Carbonate (RSC), Electrical Conductivity (EC), Kelly’s Ratio (KR), Total Hardness (TH), Chloride-Bicarbonate Ratio (CB Ratio), Magnesium Hazard (MH), Permeability Index (PI), and Gibbs Ratio, were calculated to assess irrigation suitability. Results revealed that one inlet sample fell into the C4-S3 category (very high salinity, high sodium), while most samples were classified as C4-S2 (very high salinity, medium sodium). High EC and sodium levels indicated unsuitability for irrigation, particularly in poorly drained soils. The Wilcox Diagram confirmed most samples were unsuitable for irrigation due to high salinity. Diluting treated effluent with low TDS water (<500 mg/L) in a 2:1 ratio could improve suitability.

Background: Elderly was applied to individuals aged 60 years and above. Falls are a significant problem because they result in substantial morbidity and mortality. Several factors increase the risk of falling in older people, such as muscle weakness, gait and balance impairment, neurological dysfunctions, and cognitive decline. This work aimed to study the gait and balance impairments in geriatrics regarding possible etiologies, clinical and radiological approach for diagnosis, as well as their effect on quality of life.
Methods: The current study was an observational cross-sectional study carried out on 60 subjects aged > 61 years and 40 subjects aged ≤60 years, who were relatives of outpatient clinic patients. Studied individuals were subjected to clinical and digital gait analysis and brain as well as cervical DTI.
Results: The age of included geriatrics was 61-79 years and 88.3% were males. There was a significant change in AADLs, the SARC-F scale, the MoCA scale, and the DGI scale in older adults. Instrumental gait assessment revealed a significant decrease in gait speed, cadence, swing phase, and stride length, and a significant increase in stride time, contact phase, and double support phase. There was a significant correlation between gait speed and age as well as the degree of sarcopenia.
Conclusion: Gait speed in the elderly had an inverse correlation with age and sarcopenia and a significant relation with diabetes mellitus, cardiovascular diseases, and sex. Sex and sarcopenia were risk factors for slow gait speed in the elderly.

Aims: To evaluate the effectiveness of various bio-pesticides viz, Azadirachtin 1500ppm @ 5ml/lit, garlic extract @ 5ml/lit, biogreen-L @ 5ml/lit, Azadirachtin 1500ppm @ 5ml/lit + garlic extract @ 5ml/lit, Azadirachtin 1500ppm @ 5ml/lit + biogreen-L @ 5ml/lit, garlic extract @ 5ml/lit + biogreen-L @ 5ml/lit, Azadirachtin 1500ppm @ 5ml/lit + garlic extract @ 5ml/lit + biogreen-L @ 5ml/lit against sucking pests of tomato like aphid, whitefly and jassid.
Study Design: Field experimentation, Randomized Block Design.
Place and Duration of Study: The study was conducted at the experimental farm for PG research, Biswanath College of Agriculture, Sonitpur during Rabi, 2022-23.
Methodology: The population of aphid, Aphis craccivora Koch; whitefly, Bemisia tabaci (Genn) and jassid, Amrasca biguttula biguttula (Ishida) were recorded on five plants selected randomly in each plot, considering three leaves upper, middle and lower. The population of coccinellid and spider were recorded by counting their numbers on five plants selected randomly in each plot. For the study of effectiveness of various bio pesticides, the pest infestation was recorded one day ahead of each application (pre-treatment record) and third, seventh and fifteenth days after the application of bio pesticides (post treatment record).
Results: The results reveals that among different treatments, Aphis craccivora population found to be significantly lower in Azadirachtin 1500ppm @ 5ml/l + biogreen-L @ 5ml/l treated plot followed by Azadirachtin 1500ppm @ 5ml/l + garlic extract @ 5ml/l, biogreen-L @ 5ml/l after first spray and second spray. After both first and second spray Bemisia tabaci population was recorded lowest in Azadirachtin 1500ppm @ 5ml/l + biogreen-L @ 5ml/l treated plot followed by Azadirachtin 1500ppm @ 5ml/l + garlic extract @ 5ml/l and Azadirachtin 1500ppm @ 5ml/l treated plot, respectively. Among different treatments, Amrasca biguttula biguttula population was recorded to be lowest in Azadirachtin 1500ppm @ 5ml/l + garlic extracts @ 5ml/l treated plot followed by Azadirachtin 1500ppm @ 5ml/l + biogreen-L @ 5ml/l treated plot after first and second spray. Garlic extracts @ 5ml/ l + Biogreen-L @ 5ml/ l was found least effective against all the insect pests. The population of natural enemy (coccinellid) was more in Azadirachtin 1500ppm @ 5ml/l treated plots after first and second spray. However, no significant different was observed among the treatments in maintaining spider population. From the present investigation, it was found that all the bio-pesticides were congenial for population build-up of natural enemy.
Conclusion: To confront various environment and health hazards caused by these persistent and non-biodegradable insecticides it is indispensable to use bio-pesticides as these are biodegradable in nature and also proved to be safe for the population build-up of natural enemies.

Late reports on the application of black phosphorene for gas sensing have raised great attention to this remarkable 2D material. In this regard, the sensing behavior of phosphorene toward a group of volatile organic compounds (VOCs) is scrutinized. The studied gas molecules are acetone, ethanol, methanol, and toluene as main members of VOCs, along with CO2and H2O gas molecules. The adsorption of the gases on the pristine and Pd‐decorated phosphorene is studied by employing first‐principles density functional theory (DFT) combined with non‐equilibrium Green's function (NEGF). It is divulged that the selected molecules are weakly adsorbed upon the pristine phosphorene, but after decoration with Pd atom, the adsorption energy, and net charge transfer are improved. It is discovered based on the moderate adsorption energy and large charge transfer for acetone on the Pd‐decorated phosphorene that it can be a suitable sensor for acetone detection. Additionally, recovery time of 2.57 s at the temperature of 350 K, and under ultraviolet (UV) light is achieved after decoration for detection of acetone. Therefore, the authors' theoretical investigations help to better understand the adsorption mechanism of Pd‐decorated phosphorene as a gas sensor and provide a facile approach to broaden its application in industrial, medical, and environmental monitoring.
Globalization and political economy of food policies: Insights from planting restrictions in colonial wine markets
Authors: Meloni Giulia , Swinnen Johan
Published: October 2021

Globalization transforms not just the economics of production and exchange in the world, but also the political economy of public policies. We analyze how wine regulations, and more specifically planting rights restrictions, have been affected by globalization. We study colonial expansions of wine producing empires and find that (a) planting right restrictions and compulsory uprooting of vineyards are introduced to deal with falling wine prices as colonial wine production takes off and expands; (b) that enforcement of the restrictions and uprooting was difficult and often imperfect; and (c) that there was a strong persistence of the policies: after their introduction, the restrictions remain in place for a long time (often centuries) and they are only removed after major shocks to the political economy equilibrium.

Published: October 2021

A direct difunctionalization method of alkenes with quinoxalin‐2(1H)‐ones and sodium sulfonates toward sulfone derivatives has been developed under environmentally friendly conditions. This strategy represents an efficient and practical difunctionalization of olefins using water/aqueous media as a sustainable solvent. In addition, this transition metal‐free reaction is high yield, and operationally simple, and in particular, proceeds under mild conditions to afford desired sulfones with high functional group compatibility.
Infraleichtbeton für den Geschosswohnungsbau – Zusammenfassung und Vergleich des Forschungsstands zu GWP und thermischen Speichereffekten
Authors: Mendgen Anna , Schlaich Mike
Published: October 2021

Infraleichtbeton wird seit mehr als 15 Jahren am Fachgebiet Entwerfen und Konstruieren – Massivbau der TU Berlin erforscht. Im Gegensatz zu anderen Dämmbetonen kann man mit Infraleichtbeton, aufgrund seiner Festigkeit, auch mehrgeschossige Gebäude errichten.

Die Kritik am Werkstoff Beton wegen des hohen CO2‐Ausstoßes bei der Herstellung von Zement ist aktuell. Infraleichtbeton hingegen unterscheidet sich in vielen grundlegenden Eigenschaften von Normalbeton. In diesem Beitrag werden zunächst die spezifischen Unterschiede im Vergleich zu Normalbeton aufgezeigt. Es folgt die Erörterung des Verbrauchs und der Verfügung von Ressourcen im Vergleich zu Holzbau und zu Wärmedämmverbundsystemen (WDVS), anschließend werden verschiedene Forschungsergebnisse zur Ökobilanz in Bezug auf das Treibhauspotenzial verglichen. Darauf aufbauend wird der bei der Berechnung von Ökobilanzen vernachlässigte Einfluss der Speichermasse auf Kühl‐ und Heizenergiebedarf genauer betrachtet. Abschließend wird eine erste Einordnung in Bezug auf den Einfluss des Treibhauspotenzials des Werkstoffs Infraleichtbeton im Vergleich mit anderen Werkstoffen bzw. Bauweisen vorgenommen.

In Teil 1 dieser Aufsatzserie zum Forschungsvorhaben „Mehr als nur Dämmung – Zusatznutzen von Dämmstoffen aus nachwachsenden Rohstoffen (nawaRo‐Dämmstoffe)” wurden die experimentellen Untersuchungen zum Auslösen, Verlauf und Löschverhalten von Schwelprozessen in nawaRo‐Dämmstoffen, der Wirkung von Flammschutzmitteln und denen im Zersetzungsprozess freigesetzten Emissionen dargestellt. Im vorliegenden Beitrag werden die Untersuchungen zur bautechnischen Verwendung von nawaRo‐Dämmstoffen, anstelle einer nichtbrennbaren Dämmung, im Gefach von Holztafelbauweisen dargestellt. Zunächst werden die Ergebnisse eines Großbrandversuchs zum Naturbrandverhalten von Holztafelbauteilen mit nawaRo‐Dämmstoffen präsentiert. Anschließend wird die Entwicklung analytischer und numerischer Modelle für den Nachweis der raumabschließenden Funktion veranschaulicht. Den Abschluss des Beitrags bildet ein Ausblick auf das Forschungsprojekt „PyroProBiD”, in welchem erweiterte Transport‐ und Reaktionsmodelle entwickelt werden.
