Published: March 2023

AbstractThe adaptability of halophytes to increased soil salinity is related to complex rhizosphere interactions. In this study, an integrative approach, combining culture-independent and culture-dependent techniques was used to analyze the bacterial communities in the endorizosphere of indigenous succulent halophytes Salicornia europaea, Suaeda maritima, and Camphorosma annua from the natural salt marshes of Slano Kopovo (Serbia). The 16 S rDNA analyses gave, for the first time, an insight into the composition of the endophytic bacterial communities of S. maritima and C. annua. We have found that the composition of endophyte microbiomes in the same habitat is to some extent influenced by plant species. A cultivable portion of the halophyte microbiota was tested at different NaCl concentrations for the set of plant growth promoting (PGP) traits. Through the mining of indigenous halotolerant endophytes, we obtained a collection representing a core endophyte microbiome conferring desirable PGP traits. The majority (65%) of the selected strains belonged to the common halotolerant/halophilic genera Halomonas, Kushneria, and Halobacillus, with representatives exhibiting multiple PGP traits, and retaining beneficial traits in conditions of the increased salinity. The results suggest that the root endosphere of halophytes is a valuable source of PGP bacteria supporting plant growth and fitness in salt-affected soils.

Published: March 2023

Abstract
Background
The retinae of diurnal vertebrates have characteristics. Most lizards are strictly diurnal, and their retinal morphology is still unknown.

Materials and methods
The retina of the African five-lined skink (Trachylepis quinquetaeniata) was studied using light and transmission electron microscopy.

Results
The retina's ten layers were all detected. The inner nuclear layer was the thickest by an average of 67.66 μm, and the inner plexiform layer was 57.564 μm. There were elliptical, long cylindrical, and spherical melanosomes (small and large) in the pigment epithelial layer of the retina. The cylindrical melanosomes had a large area on the lateral surfaces of cones to increase light scatter absorption. The photoreceptor layer of the retina had cones only. There were single and double cones, with the double cones consisting of principal and accessory cones. The cones had inner and outer segments separated by oil droplets. A spherical paraboloid body existed between the limiting membrane and the ellipsoid. All single cones had a paraboloid, and double cones had a large paraboloid in the accessory cone. The presence of paraboloids and large ellipsoids with mitochondria of varying sizes may have helped focus the light on cone segments.

Conclusion
The African five-lined skink's eye was light-adapted due to a variety of retinal specializations related to the demands of its diurnal lifestyle in its environment.
Uncovering hidden abilities for participation in research through photo-elicitation interviews: a view on participatory research with people living in residential care facilities

Published: March 2023

Abstract
Background
Participatory research has been described to improve the relevance of research findings for the society in terms of quality of healthcare services and other public benefits. Nevertheless, there is limited guidance on how to conduct participatory research, and especially in relation to persons living in residential care facilities. To make the voices of this group heard, we therefore take a stance in the democratic approach to participatory research, and we have applied the theoretical framework Model of Human Occupation (MoHO) on participation to evaluate photo-elicitation interviews as a participatory research method with this group.

Methods
A total of 13 persons living in two residential care facilities were involved in the study and asked to take photographs of their everyday life over one week. They were then invited to an individual interview to narrate the meaning of the photographs and to describe how they experienced the photo-elicitation method. The interviews were analysed in the six steps of theoretically driven reflexive thematic analysis.

Results
The findings are described in the theme ‘Uncovering hidden abilities for participation in research’ that describes how photo elicitation interviews facilitated the older persons’ participation in research. This is illustrated by four sub-themes: ‘Bridging the ageing body’, ‘Altering habituation to everyday life’, ‘Empowering storytelling’, and ‘Negotiating the institutional culture’.

Conclusions
Our study findings support further application and evaluation of photo-elicitation interviews as a method for participatory research in residential care facilities. The major finding is how photo-elicitation interviews were used to reduce the impact of the institutional culture on the older persons’ participation in research. The method is, however, not without limitations and we encourage researchers to study the dynamic relationship between physical, social, and cultural aspects of residential care facilities in relation to the use of photo-elicitation interviews with the persons living there.

Published: March 2023

Introduction and purpose: Primary amenorrhea is not a common problem, but it is a cause for concern to the people who are affected by it as well as for their guardians. There are many factors which lead to this particular condition. Making an accurate diagnosis is pivotal in order to provide the patient with correct professional treatment and restore their health.
Aim of the study: Systematic review of the existing evidence on most common reasons which lead to primary amenorrhea.
Brief description of the state of knowledge: Primary amenorrhea is a medical state, defined as a deficiency of primary menstrual bleeding in girls during their adolescence. Primary amenorrhea is diagnosed by meeting the criteria: no period by the age of 14 in the absence of growth or development of secondary sexual characteristics, or no period by the age of 16 regardless of the presence of normal growth and development with the appearance of secondary sex characteristics. There are multiple causes of this condition. Searching for a solution is heavily dependent on additional symptoms. Lack of menarche can be caused by anatomical anomalies of the female genital system, ovaries dysplasia, dysfunction of hypothalamus and pituitary gland, as well as by medical circumstances which are not included in those groups.
Summary: The important thing is to make the proper diagnosis of primary amenorrhea. Menstruation disorders are not only gynecological problems, they can also cause systemic, psychological and sexual difficulties. It might impact the future life of maturing young girls.
Hyperspectral imaging enables the differentiation of differentially inflated and perfused pulmonary tissue: a proof-of-concept study in pulmonary lobectomies for intersegmental plane mapping
Authors: Ellebrecht David B. 
Published: March 2023

Abstract

Objectives
The identification of the intersegmental plane is a major interoperative challenges during pulmonary segmentectomies. The objective of this pilot study is to test the feasibility of lung perfusion assessment by Hyperspectral Imaging for identification of the intersegmental plane.

Methods
A pilot study (clinicaltrials.org: NCT04784884) was conducted in patients with lung cancer. Measuring tissue oxygenation (StO2; upper tissue perfusion), organ hemoglobin index (OHI), near-infrared index (NIR; deeper tissue perfusion) and tissue water index (TWI), the Hyperspectral Imaging measurements were carried out in inflated (Pvent) and deflated pulmonary lobes (PnV) as well as in deflated pulmonary lobes with divided circulation (PnVC) before dissection of the lobar bronchus.

Results
A total of 341 measuring points were evaluated during pulmonary lobectomies. Pulmonary lobes showed a reduced StO2 (Pvent: 84.56% ± 3.92 vs. PnV: 63.62% ± 11.62 vs. PnVC: 39.20% ± 23.57; p<0.05) and NIR-perfusion (Pvent: 50.55 ± 5.62 vs. PnV: 47.55 ± 3.38 vs. PnVC: 27.60 ± 9.33; p<0.05). There were no differences of OHI and TWI between the three groups.

Conclusions
This pilot study demonstrates that HSI enables differentiation between different ventilated and perfused pulmonary tissue as a precondition for HSI segment mapping.
‚Hervorbringende Organe‘, ‚bildende Kraft‘?
Authors: Sophie Meincke Anne 
Published: March 2023

AbstractThis article presents Heidegger’s little-known theory of the organism developed in his 1929/30 lectureThe Fundamental Concepts of Metaphysicsand interprets it as an antithesis to Kant’s theory of the organism contained in hisCritique of Judgement(1790 and 1792/3). Heidegger drops Kant’s transcendental caveats in favour of a robust ontological understanding of organismic teleology. Moreover, Heidegger’s alternative approach draws attention to the fact that Kant’s notion of a ‘natural end’ (Naturzweck), by being tied to the idea of intelligent design, still places the organism too close to the machine, notwithstanding assumptions of a ‘formative force’ (bildende Kraft) and ‘productive organs’ (hervorbringende Organe). Heidegger, in contrast, analyses organismic purposiveness in terms of an instinctual capacity (triebhafte Fähigkeit) in which an organism’s organs are ontologically grounded as its products, and which explains the specificity of an organism’s wholeness, motility and relation to the world.
Das Phänomen der Verlegenheit und seine Rolle im personalen Lebenszusammenhang
Authors: von Kalckreuth Moritz 
Published: March 2023

Abstract
The aim of this paper is to provide a basic understanding of the phenomenon of embarrassment by connecting two general questions. Starting with two illustrative examples, it first examines how the phenomenon could be described and what different aspects can be identified. Apart from having an obvious affective or emotional aspect and being embodied in various forms of expression, embarrassment can be considered as having a social aspect because of its close connection to the social setting of a situation. Furthermore, it seems to have an atmospheric quality in that it is experienced not only by the embarrassed person but also by all those present. Secondly the role that embarrassment plays in the context of a person’s life is addressed. Though it is experienced as unpleasant, it can be understood as a form of adequately responding to certain social situations structured by ambiguity.
Zur Bedeutung von Verlegenheit für einen Begriff politischer Öffentlichkeit
Authors: Felgenhauer Katrin , Lehmann Robert 
Published: March 2023

Abstract
The paper examines the significance of embarrassment for a concept of political publicity. It is critical of how the common interpretation of this apparently social phenomenon as a “milder form of shame” leads to a functionalist interpretation. According to this interpretation, embarrassment regulates given normative structures by initiating or even motivating self-criticism. In contrast, the article shows, first, that embarrassment cannot occur at all in a public sphere that is thought of exclusively in normative terms, and second, that the phenomenon is primordially not reflexive. In embarrassment, one is not immediately “thrown back on oneself” but tries to find a relation to one’s public figure. A philosophical reflection on this pursuit reveals the constitution of normative structures. In this light, embarrassment presents itself as a genuinely political phenomenon.
Philosophie aktuell: Public Philosophy – brauchen wir das?
Authors: Marlen Esser Andrea 
Published: March 2023

Abstract
In recent years, calls for philosophy to interact more with the public have grown louder in the German-speaking world as well as elsewhere. Public philosophy, as it were, has a long-standing tradition, reaching back to Enlightenment-era German “Popularphilosophie” and of course to Socrates and the Sophists. This section presents four short articles on some current aspects of the public-philosophy debate: on the overall conditions for transferring content from academic philosophy to the public in Germany; on the relations between philosophers’ mediatic presence and their disciplinary expertise; on 18th-century guidelines for accessible philosophical writing; and on public philosophy as a social practice that is more than mere unidirectional knowledge transfer.

Abstract
Over the past few decades, nanotechnology has shown promising prospects in biomedicine and has a proven impact on enhancing therapeutics by facilitating drug delivery. The present study brings an amalgamation of nanoscience and “clean technology” by fabricating nature-friendly nanoparticles (NPs) sans the use of chemical surfactants using Indian mustard seed, Brassica juncea L. The as-synthesized NPs were characterized to assess their average size, crystallinity, morphology, and constituent functional groups through conventional techniques: dynamic light scattering (DLS), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR). The NPs were crystalline in nature and exhibited a mean size of 205.5 nm (PDI of 0.437) being primarily polygonal in shape. Additionally, the therapeutic efficacy of the green NPs was evaluated based on their cytotoxic effect against two human cancer lines, MCF-7 and HepG-2. Both the NPs and the bulk seeds showed a dose-dependent cytotoxic effect. However, an assessment of the antiproliferative/cytotoxic potential of the green NPs versus the bulk seeds showed that the NPs were relatively more efficacious on both cell lines. Taken together, the mustard seed NPs could be potential nutraceuticals considering the green credential in their mode of biosynthesis.

Published: March 2023

Abstract
A new environmental friendly flame retardant manganese phytate (MnPa) was prepared by a direct precipitation method and the polyurethane foam (PUF) modified with MnPa was obtained by a one-step all-water foaming method. The thermal stability and combustion performance of the MnPa-modified PUF (MnPUF) were investigated by using thermogravimetric (TG), thermal decomposition kinetics, smoke density characterization, limiting oxygen index (LOI) and UL-94 horizontal combustion test. The results indicated that the addition of MnPa significantly improved the thermal stability and combustion performance of the modified PUF. On the basis of the thermogravimetric analysis, Flynn-Wall-Ozawa method, Kissinger method and Coats Redfern method, it could be concluded that PUF with 7.5 wt% MnPa (MnPUF3) had the highest activation energy and the best thermal stability. Smoke density analysis, LOI and horizontal combustion analysis also showed that the addition of MnPa was positively correlated with smoke suppression, LOI value and burning time. The current research results can provide a reference for the subsequent flame retardant modification of PUF.

Abstract
The main objective of this study was to analyze the microstructural characteristics and strength performance of dissimilar AISI 431 steel/AISI 1018 steel joints developed using rotary friction welding. The microstructural characteristics of different regions of dissimilar rod-to-plate joints were analyzed using optical microscopy. The tensile properties and microhardness of dissimilar rod-to-plate joints were evaluated to assess the joint performance. The microhardness distribution across the cross-sectional region of dissimilar rod-to-plate joints was recorded and correlated with the tensile failure. Scanning electron microscopy was used to analyze the fractured region of dissimilar rod-to-plate tensile specimens. Results showed that the dissimilar AISI 431 steel/AISI 1018 steel joints steel exhibited a tensile strength of 650 MPa, a yield strength of 452 MPa, and a % elongation of 18%. The microhardness of the weld interface (WI) was higher up to 515 HV0.5. The grain growth and resulting lower hardness in heat-affected zone (HAZ) are mainly responsible for the failure of the joints in HAZ only. The superior tensile properties and greater interface hardness of dissimilar AISI 431 steel/AISI 1018 steel joints are correlated with the evolution of finer grain microstructure in the WI zone.
Wear performance analysis of B4C and graphene particles reinforced Al–Cu alloy based composites using Taguchi method
Authors: Sachit T. S. , Bongale Arunkumar , Kumar Satish , Jadhav Priya 
Published: March 2023

Abstract
In this study, the wear performance of boron carbide (B4C) and graphene (Gr) particles reinforced Al–Cu alloy composites was investigated. The composite samples were made using the solid-state manufacturing process. The wear performance was assessed using a pin-on-disc tribometer. The Taguchi optimization approach was used to determine the performance of each parameter. All experiments were carried out using the L27 array, which included three sets of parameters such as applied load, disc speed, and reinforcement percentage. The ANOVA approach was used to examine the impact of each parameter. According to the findings, the weight on the pin has the greatest influence on wear, followed by sliding speed and reinforcing percentage. The addition of B4C particles improves the wear resistance, and the Gr functions as a self-lubricating agent while in use. Scanning electron microscope analysis of worn-out samples revealed an abrasive type of wear process.
Word prosody of African versus European-origin words in Afro-European creoles
Authors: Agostinho Ana Lívia 
Published: March 2023

Abstract
This paper is concerned with word-prosodic systems of Afro-European creole languages that show a correlation between the lexical origin (African vs. European) and prosodic pattern. The discussion is based on the evidence from four languages: Saramaccan, Nigerian Pidgin English, Pichi, and Lung’Ie. I examine how the study of word-prosodic systems of creoles can contribute to phonological typology and to the debate of whether creoles are different from non-creoles. I hypothesize that such systems are the result of extreme language contact and can only be found in creole languages. The existence of these systems further confirms that sociohistorical processes – such as historic contact – can shape phonological systems. Finally, I conclude that the analysis of African-origin words is crucial to further our understanding of creole phonology.

Published: March 2023

AbstractIn order to effectively upgrade the training quality of the athlete, the study of the three-dimensional optical steps of sports, a three-dimensional optical action amplitude tracing process based on improved reverse kinematics is discussed. The method passes through a pinhole camera, the model calibrate the camera imaging plane, the positioning mark appears in the marker point in the apart neighboring single-sequence action amplitude and then the five-point perspective imaging of the same line is captured on the same straight line by the camera on different positions and postures. The matching method’s accuracy and superiority are demonstrated through experimental evaluation and compared with other similar measures. This characteristic is distinguished by the left and right image frames of the same camera. The translational movement is altered in 10–80 mm/s and the rotational movement is adjusted in 10–300 mm/s. During the confirmation, the spinning of the operational target, the longitudinal movement and the spatial location of the rotation point Measurement, the calculation variability of the stereoscopic visual moving calculation system, is given, and the method of tracking the method is high, which lay the foundation for the promotion of the training quality of the athlete. The experimental findings from simulation demonstrate that the implemented approach has great searching accuracy, establishing a solid platform for further improving the quality of athletes’ training.

Abstract
The influence of anthropogenic activities has led to increase of potential toxic elements (PTEs) present in plant-based food sources, even in trace amounts; thus, it is known to pose a threat to human health over an extended period. The concentration levels of PTEs (Pb, Cu, Zn, Cd, Co and Ni) in soils and fruits and vegetables from three markets (Atani, Omor and Eke Awka) in Anambra state, Southeastern Nigeria were quantified and assessed using Atomic Absorption Spectrophotometer (AAS) instrument. The result of PTE (mg/kg) studied was in the order Zn > Cu > Pb > Ni > Co > Cd with the highest value for Zn (13.61 mg/kg) recorded in soil sample at Omor market. The mean concentrations of PTEs in soil of both evaluated studied areas were lower than the WHO permissible limits for PTEs in soil. Among the fruits and vegetables, Bitter leaf had highest PTE from Eke Awka followed by banana, fluted pumpkin, water leaf and onion. Fluted pumpkin had the highest PTE content from Omor followed by watermelon, water leaf, onion and cucumber, while water leaf had the highest metal concentration from Atani followed by bitter leaf, fluted pumpkin, cucumber, lettuce and carrot. Health risk assessment showed that hazard index (HI) in decreasing order was Eke – Awka market > Omor market > Atani market across all fruits and vegetables, as adverse health effect is not expected. The present study recommends containment measures of potential toxic elements in soils and fruits/vegetables to prevent excessive accumulation in food value chain.
