Low ice adhesion anti-icing coatings based on PEG release from mesoporous silica particles loaded SBS
Authors: Ijaz Aatif , Miko Annamaria , Demirel Adem Levent
Published: July 2022

Release-based extremely low ice adhesion strength and durable anti-icing coatings were designed and realized by loading mesoporous silica particles (MSP) into SBS polymer matrix and filling poly(ethylene glycol) (PEG) as the anti-icing agent into MSP/SBS composites. This approach allows the formation of a thin lubricating liquid layer of PEG and water at the ice/composite interface at sub-zero temperatures and results in ice adhesion strengths as low as 3 kPa. The high specific surface area of MSP (428 m2 g-1) as the anti-icing agent carrier significantly contributed to the retainment of PEG in the composites. The freezing time of water droplets on the composites increased and the ice adhesion strength decreased with the amount of PEG retained in the composites. After 15 icing/deicing cycles, the ice adhesion strength was measured to be ~5 kPa indicating that a rather slow release (and removal with ice) of PEG at -10 °C from surface-exposed pores of MSP. The importance of PEG at the ice/composite interface was confirmed by ice adhesion strength measurements of frozen PEG-containing aqueous solutions on unfilled MSP/SBS composites. These results clearly show that PEG filled MSP/SBS composites demonstrate a passive anti-icing mechanism based on sustained release of PEG with extremely low ice adhesion strength and significant potential for longer-term use in sub-zero temperatures and harsh environments.
Structure-dependent Photoluminescence from MA1-xFAxPbI3 with Evidence of Defect-suppression on FA-substitution
Authors: Mohanty Ashutosh , Sarma D. D.
Published: July 2022

We present temperature-dependent photoluminescence (PL) spectra from MA1-xFAxPbI3 for x = 0.02, 0.15, 0.2, and 0.6 over the temperature range of ~12-300 K. These results show remarkable changes across the structural phase transitions together with presence of multiple peaks, prominently in the low temperature regime, that can be associated with different crystallographic phases apparently coexisting at low temperatures. We propose that the persistent dominant presence of the PL signal associated with the high temperature tetragonal/cubic phase in each case even at the lowest temperature can only originate from a structural relaxation at the surface of the grains of the low temperature phase, making the surface electronic structure close to that of the high temperature phases. Since the bandgap is smaller for the surface related phase, the photoexcited energy is significantly transferred to the surface region before deexcitation, giving rise to the dominance of this PL feature. Our results show that with an increasing FA content, this transfer of energy becomes more efficient with a complete suppression of the PL features of the low temperature bulk phase, while the x-ray diffraction shows a phase pure low temperature phase alone. Additionally, we show that the lowest energy PL feature that appears only at a critical low temperature is not associated with any crystallographic transition, but correlates well with the plastic crystal-like transition arising from the three-fold rotations of the MA unit around its C-N axis as determined by prior quasi-elastic neutron scattering studies. This suggests that the MA rotations suppress the formation of self-trapped excitonic features via electron-phonon interactions, while the feature begins to appear with increasing intensity as the MA rotations are frozen with a decreasing temperature below a certain temperature. This interpretation allows us to estimate the polaronic contribution to the stability of the self-trapped exciton in these systems to be around ~35 ± 3 meV. Interestingly, the PL spectrum progressively shows a suppression of contributions from the low temperature phases and the self-trapped exciton with an increasing FA content, leading to a single peak PL feature at all temperatures for the highest FA content sample investigated in this work.

Published: July 2022

Electrohydrodynamic redox 3D printing (EHD-RP) is an additive manufacturing (AM) technique with submicron resolution and multi-metal capabilities, offering the possibility to switch chemistry during deposition ”on-the-fly”. Despite the potential for synthesizing a large range of metals by electrochemical small-scale AM techniques, to date, only Cu and Ag have been reproducibly deposited by EHD-RP. Here, we extend the materials palette available to EHD-RP by using aqueous solvents instead of organic solvents, as used previously. To demonstrate significant extension of potentially accessible metals, we show deposition of Cu and Zn from sacrificial anodes immersed in acidic aqueous solvents. Mass spectrometry indicates that the choice of the solvent is important to the deposition of pure Zn. Additionally, we show that the deposited Zn structures, 250 nm in width, can be partially converted into semiconducting ZnO structures by oxidation at 325 °C in air.

Unravelling the structural diversity of cellular membranes is a paramount challenge in life sciences. In particular, lipid composition affects the membrane collective behaviour, and its interactions with other biological molecules. Here, the relationship between membrane composition and resultant structural features was investigated by surface pressure-area isotherms, Brewster angle microscopy and neutron reflectometry on in vitro membrane models of the mammalian plasma and endoplasmic-reticulum-Golgi intermediate compartment membranes in the form of Langmuir monolayers. Natural extracted yeast lipids were used because, unlike synthetic lipids, the acyl chain saturation pattern of yeast and mammalian lipids are similar. The structure of the model membranes, orthogonal to the plane of the membrane, as well as their lateral packing, was found to depend strongly on their specific composition, with cholesterol having a major influence on the in-plane morphology, yielding a coexistence of liquid-order and liquid-disorder phases.

The worldwide re-emerge of the Chikungunya virus (CHIKV), the high morbidity associated with it, and the lack of an available vaccine or antiviral treatment make the development of a potent CHIKV-inhibitor highly desirable. Therefore, an extensive lead optimisation was performed based on the previously reported CHVB compound 1b and the reported synthesis route was optimised - improving the overall yield in remarkable shorter synthesis and work-up time. 100 CHVB analogues were designed, synthesised, and investigated for their antiviral activity, physiochemistry, and toxicological profile. An extensive structure-activity relationship study (SAR) was performed, which focused mainly on the combination of scaffold changes and revealed the key chemical features for a high anti-CHIKV inhibition. Further, to investigate the druggability of the compound series, a thorough ADMET investigation was carried out: the compounds were screened for their aqueous solubility, lipophilicity, their toxicity in CaCo-2 cells, and possible hERG channel interactions. Additionally, 55 analogues were assessed for their metabolic stability in human liver microsomes (HLMs) which led to a structure-metabolism relationship study (SMR). The compounds showed an excellent safety profile, favourable physicochemical characteristics, and the required metabolic stability. A cross-resistance study confirmed the viral capping machinery (nsP1) to be the viral target of these second-generation CHVB compounds. This study identified five compounds (31b, 31d, 32d, 34, and 35d) as potent, safe, and stable lead compounds for further development as selective CHIKV inhibitors - with 32d as the most promising candidate. Finally, the collected insight led to a successful scaffold hop (64b) for future antiviral research studies.

Published: July 2022

The different types of skin diseases caused due to microorganisms. In recent years the use of the traditional medicinal system was increased because of more minor side effects and cost effective. The single herbal drugs were found to be less potent, which can be improved by utilizing more than one herb in the single formulation, known as polyherbal formulation. The present work involved the development and evaluation of the different polyherbal formulations (cream, gel, and emulgel) using natural ingredients.  The aim  of the present work is to produce a formulation with improved antimicrobial potency and stability of formulations when compared with the individual extracts of herbal drugs. All the prepared formulations were tested against various microbial strains and concluded that the polyherbal formulations (C25, G1, EG1) were found potent against most selected strains. The prepared formulations can be used as a multipurpose formulation.

Published: July 2022

Ayurvedic medications are becoming more popular among physicians and patients due to their superior therapeutic value. Guggulsterone is a plant sterol found in guggul resin. Obesity bone fractures, arthritis, inflammation, cardiovascular disease, diabetes, hyperlipidemia, atherosclerosis, and osteoarthritis have all been treated with the resin in Ayurveda from ancient times. In this study, a technique for standardising the marker E-guggulsterone was created. The regresion analysis results for the E-guggulsterone calibration plot revealed a linear connection with a correlation coefficient of r2 = 0.9995, indicating that the amount of E-guggulsterone in the samples will  be exact and accurate. This approach was proven to be exact, accurate, and resilient and may be used to analyse samples regularly.
Fake News and Democracy
Authors: Reglitz Merten
Published: July 2022

Since the Brexit Referendum in the United Kingdom and the election of Donald Trump as US President in 2016, the term ‘fake news’ has become a significant source of concern. Recently, the EU Commission and the UK Parliament have condemned the phenomenon as a threat to their democratic processes and values. However, political disinformation is nothing new, and empirical studies suggest that fake news has not decided crucial elections, that most readers do not believe the online fake news stories they read, and that political polarization in Western democracies like the US began to increase long before online fake news existed. The question then is: how exactly does fake news threaten democracies? This paper argues that online fake news threatens democratic processes because it undermines citizens’ epistemic trust in each other. This in turn threatens to undermine the perceived legitimacy of democratic institutions as a whole. While online fake news is a symptom of a much larger issue (how has the Internet affected democracies, and how can we use its positive power while checking its potential harms?), it deserves particular attention given the potential danger it presents for the viability and the legitimacy of the democratic process.

To measure thermal resistance to heat flow at 1600ᴼc in a compound heating resistance furnace for optimization of furnace efficiency
Authors: Ranjib K. Chowdhury , Krupashankara M. S.
Published: July 2022

The present paper examines the performance of a resistance heating furnace by measuring the resistance of two different heating elements, namely, Silicon Carbide (SiC) heating rods and Molybdenum Di-Silicide (MoSi2) heating elements, to raise the working chamber temperature to 1600ᴼC for heating the charge materials. SiC rods are used to raise the working chamber temperature, starting from the beginning (ambience) temperature of 35ᴼC up to 1300ᴼC. Then MoSi2 heating elements will be used to raise the chamber temperature from 1300ᴼC to the set temperature at 1600ᴼC. Transition from SiC to MoSi2, heating system is uninterrupted, and swift in heating element effected by inter-locking system (an electronic device or an electro-magnetic system) without any drop in effect. Use of two different heating elements has been tested to achieve many objectives, like saving amperage (current consumption), long life of the heating elements, and optimization of thermal efficiency for high working temperature at 1600ᴼC for long hours. This is achieved by creating resistance to the flow of electrons through an element (a good conductor for electricity as well as heat). Thus, due to high friction, a temperature is developed and heats the charged materials, up to a temperature as high as 1600ᴼC. This method is applied in an environment of air, inert gas, vacuum, etc. with no pollution, for programmable and also for non-programmable types of cycles of operations set before starting the furnace within a maximum working temperature of 1600ᴼC to achieve the objectives of a Compound Heating Resistance (CHR) furnace satisfactorily.
Comparative analysis of real-time data for stand-alone PV and floating PV system using MPPT technique
Authors: Monika Mandav , Shruti Tiwari
Published: July 2022

Solar energy is one of the most important and rapidly developing technologies in India. In recent years, India's attempts to increase the share of solar energy in electricity generation have led to the use of all renewable energy sources in electricity generation. It does not require fuel and has no negative impact on the environment. This research paper compared real-time data for off-grid and floating Photovoltaic (PV) systems. A stand-alone photovoltaic system assumes that a battery is used to store energy. He encountered a problem with the heating on the ground or on the roof, causing the panel's efficiency to drop. A floating solar panel is a novel solution to the problem of scarce land and rising panel temperatures in standalone systems. The efficiency of a floating PV system is higher than that of a stand-alone PV system because the water constantly cools the temperature of the floating solar panel. This paper explored the performance of both standalone and floating PV modules. The systems used the Maximum Power Point Tracking (MPPT) approach and the simulations were performed in MATLAB. Other MPPT algorithms are available, but this is the one uses the Perturb and Observe (P & O) technique.
Whakawhanaungatanga A-Reo: An Indigenous Grounded Theory for the Revitalization of Māori Language Speech Communities
Authors:   , Pohe Ewan James
Published: July 2022

This study focuses on the role of adult Māori language acquisition in the revitalization of the Māori language. Māori language transmission is now primarily dependent on transmission through educational institutions. The objective of Māori language revitalization is to re-establish intergenerational language transmission. Language shift means that intergenerational language transmission of the Māori language has effectively ceased in Māori homes and communities. This means Māori once again becomes the primary language spoken in the home, neighbourhood and community domains. This is a report of a grounded study of an adult cohort of novice language learners. A group of mainly Māori who joined a Te Ataarangi total immersion programme where they were immersed in both the Māori language and the culture over a three year period. I was a participant observer of the cohort and collected data in the form of field notes and interviews on the experiences of its members. Following classical Grounded Theory Methodology (GTM) (Glaser 2002), I used constant comparative analysis of incidents to iteratively analyse the data and evolve the conceptual framework. The central finding of this study is the process of whakawhanaungatanga a-reo. I found that the shared objective in acquiring the Māori language for the cohort was to be able to use the language appropriately in ordinary communicative situations. The way their objective was met is represented in a three-stage process of whakawhanaungatanga a-reo. Whakawhanaungatanga a-reo is a process by which the cohort evolves from manene, to ako ngātahi and finally to a whānau ā-reo. At the manene stage, a novice learner is in a total immersion learning environment, their main inhibitor is whakamā. Whakamā is ameliorated by the tenet of ngākau māhaki which is an attitude of tolerance and caring propagated throughout the group. Ngākau māhaki facilitated trust relationships within the group. Ako ngātahi is the second stage of the process of whakawhanaungatanga a-reo. By the ako ngātahi stage, the Māori language was the default language of use amongst the class members. Building on the level of trust built between the group’s members developed at the manene stage meant that they felt comfortable enough to mahi tahi (cooperate) and interact intensively in class learning activities. These interactions were all mediated using the Māori language as the primary language of communication. Whānau a-reo is the last stage of the whakawhanaunga a-reo process. By attending wānanga with other classes, often in different regions of New Zealand, relationships between the groups continues to develop until finally the group transitions into a whānau a-reo. Learners who reach this point are confident to continue practising the language outside of the classroom environment with members of other Māori speaking communities; such learners are the basis of language revitalization.
Stories Are the Centre: The Place of Fiction in Contemporary Understandings and Expressions of Indigeneity. Part 1, Critical Component
Authors:   , Makereti Tina
Published: July 2022

Fiction written by indigenous people is an important tool for the reclamation of histories and identities, and for the imagining of alternative possibilities. Baby No- Eyes by Patricia Grace and Benang by Kim Scott are novels that address historical and contemporary experiences from indigenous points of view and therefore call into question previously known and accepted histories. By presenting alternative content and allowing for indigenous views and voices, these texts unearth discontinuities, anomalies and multiple possibilities – ultimately creating space for the authors to open up previously constricted or single-sided views of history and identity. These texts operate like historiographic metafiction, but go further than Linda Hutcheon’s Poetics of Postmodernism. Each novel culminates in new forms of creativity, signalling evolution beyond the position of ‘talking back’ and beyond reacting to the past in a colonial / postcolonial loop. In these novels, the gap left by postmodern deconstruction is filled by uniquely and fiercely indigenous (Māori, Nyoongar) contemporary solutions. Invariably these solutions contain some reclamation of traditional values, but the presence of new forms of creativity and marban/matakite abilities in Baby No Eyes and Benang in particular, suggest that contemporary solutions lie in going further and creating new understandings and ways of being. The creative component of this thesis is a novel, Rēkohu Story, which consists of three intertwined narratives: a young woman of Moriori, Māori and Pākehā descent seeks her family’s origins; a Moriori slave and his Ngāti Mutunga mistress run away together in 1882; the spirit of a man who died during the invasion of the Chatham Islands (Rēkohu) in 1835 watches over his descendants. The impetus for this novel was the author’s own mixed cultural heritage and concern that erroneous versions of the history of Rēkohu still persist. Both the critical and creative components assert that fiction can deepen understandings and expressions of history and Indigeneity.

Published: July 2022

Campus culture is not only a symbol of culture and the style of studying, but also the overall atmosphere that helps students establish correct world outlook, values, and outlook on life. It leads the cultivation of student behavior and shapes the character of students. However, due to the openness of colleges and universities, the impact of informatization, the rapid development of society, and other factors, the campus culture in colleges and universities is affected by various aspects, and the cultivation of student behavior is bound to be affected. In this complex environment, how to promote campus culture in such a way to promote the cultivation of student behavior has become a topic of interest. The Central Committee of the Communist Party of China clearly put forward the “Opinions on Further Strengthening and Improving Ideological and Political Education” under the State Council, stating that campus culture plays an important role in educating people and it is necessary to construct a campus culture that embodies socialist characteristics, school characteristics, and the characteristics of the times [1].

This study was conducted to compare the perinatal complications for newborns by In vitro fertilization with embryo transfer (IVF-ET) and natural delivery. Respectively 50 cases of the IVF-ET and 50 cases of the natural delivery were selected from Hospital of Chengde Medical University as research subjects. All the recruited cases were selected with the newborns from April, 2021 to April, 2022. Defining the IVF-ET as the test group, while the natural delivery as the control group to compare and analyze the perinatal situations and the incidences of complications in both the groups. This study showed that the incidences of pregnancy-induced hypertension, diabetes, multiple pregnancy, premature delivery, and cesarean section in the test group were significantly (p<0.05) higher, than the control group. In addition, the incidences of neonatal respiratory distress syndrome (NRDS) and hyperbilirubinemia of newborns in the test group were statistical (p<0.05) higher, compared to the control group. In contrast, there are no statistically significant differences in terms of hypoglycemia, pneumonia, and neonatal asphyxia incidences between the two groups (p>0.05). Interestingly, there is a significant difference (p<0.05) in the incidences of neonatal cardiac anomalies in both groups, however, no significant differences (p>0.05) were observed in terms of birth defects including hypospadias, the cleft lip and palate, polydactyly, anal atresia, and esophageal atresia in both the groups. In summary, the test tube babies of IVF-ET are more susceptible to complications in their perinatal stage compared with natural delivery newborns, therefore, during the clinical development physicians should strengthen clinical attention and take proactive healthcare management, in order to maintain the health and life of the newborns.

Authors: Li Shuiqin , Wei Wei , Fan Fan , Xue Yang , Li Chaonan
Published: July 2022

Objective: To explore the modified Allen impactor method in establishing a rat model of spinal cord injury, and to preliminarily evaluate the motor function of the forelimbs and hindlimbs of rats. Methods: Thirty female SD rats with a body weight of 255 ± 21g were randomly divided into two groups, namely the sham-operated group and the operated group, with 15 rats in each group. The spinal cord injury SD rat model was established by exposing but not injuring the spinal cord in the sham-operated group, while the SD rat model was established by the modified Allen impactor method in the operated group. The Basso–Beattie–Bresnahan (BBB) rating scale was used to assess the rats’ hindlimb motor neurobehavior. A rat model of spinal cord injury was established by the modified Allen impactor method. After the cells were transplanted, the BBB score was used to evaluate the motor function; the changes in the motor function of rats with spinal cord injury were detected. Results: The motor function and sensory function of the forelimbs and hindlimbs of the rats showed significant changes after five days. The motor function of the forelimbs and hindlimbs of the rats in the sham-operated group were essentially normal after three days (about 20 points); the sensory function of the rats in the operated group decreased significantly after five days; however, in the sham-operated group, it decreased to 0. The motor function scores of the rats in the operated group at each point of time were significantly lower than those in the sham-operated group (p < 0.05), while the forelimb motor function scores were significantly higher than those in the sham-operated group (p < 0.05). Conclusion: The modified Allen impactor method that was used to establish a rat model of spinal cord injury in this study can significantly reduce the motor function of rats.

A Novel Analytical Model of Brain Tumor Based on Swarm Robotics
Authors: Mohamed Abbas
Published: July 2022

A tumor is referred to as “intracranial hard neoplasm” if it grows near the brain or central spinal vessel (neoplasm). In certain cases, it is possible that the responsible cells are neurons situated deep inside the brain’s structure. This article discusses a strategy for halting the progression of brain tumor. A precise and accurate analytical model of brain tumors is the foundation of this strategy. It is based on an algorithm known as kill chain interior point (KCIP), which is the result of a merger of kill chain and interior point algorithms, as well as a precise and accurate analytical model of brain tumors. The inability to obtain a clear picture of tumor cell activity is the biggest challenge in this endeavor. Based on the motion of swarm robots, which are considered a subset of artificial intelligence, this article proposes a new notion of this kind of behavior, which may be used in various situations. The KCIP algorithm that follows is used in the analytical model to limit the development of certain cell types. According to the findings, it seems that different KCIP speed ratios are beneficial in preventing the development of brain tumors. It is hoped that this study will help researchers better understand the behavior of brain tumors, so as to develop a new drug that is effective in eliminating the tumor cells.

The surveys involved 67 rural, suburban and urban gardens, of various sizes, ranging from 61.18° North in Norway to 37.96° South in Australia, resulting in a data set of 25,174 rows, with each row being a unique interaction record for that date/site/plant species, and comprising almost 47,000 visits to flowers, as well as records of flowers that were not visited by pollinators, for over 1,000 species and varieties belonging to more than 460 genera and 96 plant families. The more than 650 species of flower visitors belong to 12 orders of invertebrates and four of vertebrates. In this first publication from the project, we present a brief description of the data and make it freely available for any researchers to use in the future, the only restriction being that they cite this paper in the first instance. The data generated from these global surveys will provide scientific evidence to help us understand the role that private gardens (in urban, rural and suburban areas) can play in conserving insect pollinators and identify management actions to enhance their potential.

Authors: 沛艺 曾 , 嫚 唐 , 淑娟 和 , 牧青 杨
Published: July 2022

为探究砷在茶园土壤和茶叶之间迁移规律，对土壤与茶叶之间的总砷、有效态砷迁移进行研究。结果表明：在pH≤4.5的酸性土壤环境下，茶园土壤中砷含量与富集系数的相关系数最高，相关性呈现负显著，其相关系数大小依次是：（pH≤4.5）＞（4.5＜pH≤5.0）＞（pH＞5.0），随着pH值的升高，茶园土壤中砷含量与富集系数的相关系数越低，相关性越不显著；在黏质土的土壤质地下，茶园土壤中总砷含量与富集系数的相关系数最高，相关性为负显著，其相关系数大小依次是：黏质土＞砂质土＞壤土，三种土壤质地其相关性均为负显著。研究表明：茶园不同程度酸性土壤、不同土壤质地环境下，土壤中砷含量与富集系数及土壤中砷有效态含量与转移系数的相关性研究受pH值影响，随着pH值的降低，其相关系数呈现显著状态，砷越容易被茶叶吸收；在砂质土和壤土的土壤质地下，土壤中砷含量与富集系数及土壤中砷有效态含量与转移系数的相关性也呈现负显著，表明茶园土壤中砷在该两种土壤质地下迁移性比黏质土强。

Cuando se trata de hábitos alimenticios existen carácterísticas que influyen en su concepción que van desde la cultura, la economía y la geografía, es por ellos que se hace necesario el estudio del contexto para poder definirla. Se trata de la raíz histórica de cada civilización. En Ecuador, el reconocimiento de todas las nacionalidades ancentrales ha requerido de una lucha politica y social por lo cual los esfuerzos sociales y politicos rinden hoy sus frutos. En el caso de las culturas milenarias, la investigación se enfrenta a una dificultad latente. En un mundo globalizado, donde las barreras geográficas se han visto superadas por la era digital, mantener las costumbres originarias se vuleve cada vez mas difícil pues el consumo informativo sobrepasa la capacidad de control respecto a como se digiere la oferta de conocimiento. Atención en salud integral En virtud de esto, se establece la importancia de garantizar a los pueblos una atención en salud integral, la cual sea integrada y continua de la persona en los diferentes ciclos de vida, así como un nivel básico, así como de protección social en salud en condiciones adecuadas de calidad, calidez, dignidad y oportunidad. También, la influencia de la evolución de la sociedad se hace presente en los procesos productivos ancentrales, cada día las comunidades indigenas se ven afectadas por los problemas de la civilización como son la contaminación y la producción en masa de bienes que buscan un rendimiento económico por encima de la identidad cultural. Las comunidades indígenas, sobretodo, las que luchan por sobrevivir en el tiempo, han desarrollado mecanismos de defensa respecto a su historia, precisamente en un esfuerzo de mantener su identidad.
Die schönen Künste als ‚Gesundheitsmittel‘ oder tödliches Gift. Empfindungsästhetik und Theaterkritik bei Sulzer und Rousseau
Authors: Düwell Susanne
Published: July 2022

Der Beitrag untersucht die Verbindung von wirkungsasthetischen und theaterkritischen Diskursen. Begriffe wie Illusion oder Leidenschaft beschreiben in der zweiten Halfte des 18. Jahrhunderts sowohl Wirkungsziele einer anthropologischen Asthetik als auch Effekte, die als psychisch und sozial gefahrdend qualifiziert werden. Im Fokus steht die Thematisierung affektiver Wirkungen des Theaters bzw. der Kunst allgemein in ihrem heilsamen Potential durch Johann Georg Sulzer sowie die Theaterkritik Jean-Jacques Rousseaus, gegen die sich Sulzer dezidiert wendet. Ausgehend vom Konzept der ‚dunklen Vorstellungen‘ postuliert Sulzer, dass nur starke Empfindungen, nicht aber die Vernunft den Menschen sittlich und seelisch beeinflussen konnen. Vielmehr liefern extreme oder pathologische seelische Zustande ein Modell fur Kunstproduktion und -wirkung.
Pietistische Kommunikation. Konzepte der Sozialität bei Spener, Francke und Zinzendorf
Authors: Steinmayr Markus
Published: July 2022

Die forschungsleitenden Positionen zum Verhaltnis von Literatur und Religion im 17. und 18. Jahrhundert sind sich in der Uberzeugung einig, die Entstehung der Literatur an die Erklarungskraft des Modells ‚Sakularisierung‘ ruckzubinden. Sakularisierung ermoglicht eine hohe Differenzierungsleistung der religiosen Kommunikation selbst. In dieser Differenzierungsleistung stellt sie als Eigenleistung des religiosen Systems eine gunstige Umweltbedingung der Literatur dar.
„Wohl ist das Herz wach, doch mir zürnt, mich / Hemmt die erstaunende Nacht nun immer“. Die Darstellung von Schmerz und Verzweiflung in Hölderlins Ode "Chiron"
Authors: De Felip Eleonore
Published: July 2022

In Hölderlins ‚tragischer Ode‘ Chiron drückt sich im Schmerz des unheilbar verwundeten Kentauren ein persönliches wie auch ein allgemeines Leiden aus. Vers für Vers ergründet der Aufsatz Chirons ‚Innenwelt‘ und analysiert dabei Hölderlins intensitätsbasierte poetische Verfahrensweise. Der Fokus liegt auf dem Spannungs- und Entwicklungsbogen, der Hölderlins Konzept des ‚Tragischen‘ widerspiegelt. Seine Poetik kreist um Trennung und Vereinigung, um die progressive Integration von Gegensätzlichem und um die Notwendigkeit von semantischen Leerstellen.

Published: July 2022

On the market of feed and veterinary additives, there is a wide range of drugs that have a positive effect on the poultry body. We conducted a scientific and economic experiment to study the effect of a probiotic based on Bacillus subtilis on the productivity of laying hens of the Brown Nick cross. Each enterprise strives to find the most optimal solutions for its production. Thus, we have conducted a scientific and economic experiment. For the experiment, two groups of hens were selected - layers of the Brown Nick cross, of the same age. The nutrition program for both groups was the same. The difference was that the birds of the experimental group were introduced into the diet - 1000 g /t of the probiotic Bacillus subtilis. The probiotic supplementation minimized heat stress losses and prevented performance degradation. The bird of the experimental group, which was injected with Bacillus subtilis, increased the percentage of the intensity of egg production than the bird of the control. A deeper study of the use of probiotic complexes in the enzymatic system will allow producers of probiotics to reduce the cost of a feeding program for laying hens.
