Ausgehend von der Beschreibung einer Situation im Unterricht in einer inklusiven Gesamtschule einer Großstadt analysieren Elise v. Bernstorff und Carla J. Maier transkulturelle Praktiken im Hinblick auf die Performativität menschlicher und nichtmenschlicher Akteure. Ein Schüler, der vor zwei Jahren mit seiner Familie von Ägypten nach Deutschland migriert ist, liest eine Geschichte vor, die er zu einem Sammelband mit persönlichen Geschichten von jungen Menschen über alte und neue Heimatländer beigetragen hat. Wir analysieren die komplexen und verwobenen transkulturellen Aspekte, die sich nicht entlang ethnischer und nationaler Grenzziehungen zuordnen lassen, aus Perspektive der Sound Studies und des New Materialism.
Die Anbetung des Lammes
Authors: Korte Jule
Published: November 2019

Dieser Beitrag nimmt die von Milo Rau in Gent inszenierte Szene der Anbetung des Lammes zum Ausgangspunkt, um über das Verhältnis zwischen Schamgefühlen und dem Affektiven, über Relationalität und ihre (materialisierte) Bedeutsamkeit nachzudenken. Er stellt zugleich eine Reaktion auf Birgit Althans‘ Beschreibung ihrer Scham beim Schauen der Zeugungsszene dar. Der Text positioniert sich damit zwischen dem ethnographisch erhobenen empirischen Material und den dazugehörigen responses: Er ist zugleich Feldnotiz und Reaktion, und spinnt die Fäden von dieser Zwischenposition ausgehend weiter.
Computer modelling of initial platelet adhesion during microvascular thrombosis
Authors: Belyaev Aleksey V.
Published: November 2019

Hemostasis is one of the most important protective mechanisms that functions to maintain vascular integrity and prevent bleeding. In arterial and microvascular circulation, where the near-wall shear stress is relatively high, the hemostatic response begins with aggregation of platelets on the injured endothelium or collagen. Regulation of hemostasis and thrombosis is immensely complex, as it depends on the blood cell adhesion and fluid dynamics. A possible regulatory mechanism relies on the coil-stretch transitions in a plasma protein — von Willebrand factor — that serves as a ligand to platelet adhesive membrane receptors. In this work, the initial stages of thrombus growth are studied using a 3D computer model that explicitly accounts for the shear-dependent vWf conformation.

Published: November 2019

Das Urteil des Karlsruher Sozialgerichts vom Februar 2019 bedeutet einen Durchbruch für die Krankenhausseelsorge und die spirituelle Versorgung kranker Menschen. Es begründet Seelsorge nicht mit dem Grundrecht auf Religionsfreiheit, sondern aufgrund seiner Zugehörigkeit zu einem umfassenden Behandlungskonzept. Für Seelsorgende und Seelsorgeverantwortliche bringt dies allerdings auch Pflichten mit sich, die künftig zu diskutieren sind.
Urban Burial Reform in William Wordsworth’s “Village Churchyard”
Authors: Blake Katherine E.
Published: November 2019

Katherine E. Blake “Urban Burial Reform in William Wordsworth’s ‘Village Churchyard’” (pp. 279–304)

This essay looks at the relationship between space and class in nineteenth-century English burials in order to shed new light on William Wordsworth’s Essays upon Epitaphs (1810, 1876) and “The Brothers” (1800). While Wordsworth’s work dwells on pastoral images of burial, I argue that his representations in fact align more closely with the cultural practices and values underpinning urban burial conventions. Through his representation of burial space, Wordsworth’s work plays out urban concerns about burial in the countryside. Ultimately, this essay argues that the exportation of urban concerns to imaginary rural sites accounts for the utility of Wordsworth’s work to mid-nineteenth-century burial reformers, and particularly to Edwin Chadwick, a utilitarian known for his work on the 1832 Poor Law and sanitary guidelines for burial. By reevaluating what prior studies have said about Chadwick’s reforms in light of recent work on his economic theories, I argue that Chadwick’s citation of Wordsworth’s first “Essay upon Epitaphs” transforms the latter’s pastoral vision into an endorsement of a national cemetery. I explore the extent to which Wordsworth’s early-nineteenth-century ideas are and are not compatible with Chadwick’s mid-century reforms.

Preparation for gibbons before being released into their habitat is crucial. Thus, there is a need for readiness assessment of Javan gibbon with several criteria derived from other species of gibbons to determine individual readiness. Pre-release assessment study for Javan gibbon (Hylobates moloch) had been conducted in January – February 2014, November – December 2014, and March-April 2016 in the Javan Gibbon Center, Mount Gede Pangrango National Park, West Java, Indonesia. The objective of this research was to assess the readiness of Javan gibbon behavior prior to release. Data collection was conducted by focal animal sampling method with 5-minute interval recording time and ad libitum method. The average time allocations of Javan Gibbon activities were as follow: feeding (18.17±3.34%); moving (22.34±0.53%); resting (46.24±3.84%); socializing (10.13±4.33%); sexual activity (0.59±0.58%); and vocalizing (2.54±0.88%).  The similarities of activity allocation from this study compared by wild Javan gibbons data found as follows: feeding by 33.03%, moving by 90.97%, resting by 61.52%, socializing by 38.09%, vocalizing by 75.02%, and sexual by 44.24%. Based on readiness assessment of 11 Javan gibbons, 3 individuals were considered almost ready for release, while 8 individuals were considered ready. The assessment of behaviors criteria for the readiness of Javan gibbons before release has not existed before. The results of this research are important as a recommendation for the management of wildlife rehabilitation and as a guideline in implementing the rehabilitation and reintroduction program of Javan gibbons.

Published: November 2019

In Indonesia, cowpea (Vigna unguiculata L. Walp) is widely cultivated in the dry climate area. Famers used the seeds from previous plants or traditional markets. The aims of the study were to determine the effect of seed position in the pods on seed viability and to study the seed and seedling characteristics regarding the genetic variation and seed position. The cowpea used in this study was from 18 Indonesian local varieties. Twenty-five matured pods were randomly detached from each variety. Each pod was divided into three parts, i.e. the lower third (base), the middle third, and the upper third (tip). The seeds of each part were germinated using sand media to evaluate their viability. Each local variety has different response to the percentage of seed viability in each seed position in the pod. The highest abnormal germination occurred in the seed from lower part of the pod, followed by seed in the middle of the pod and the tip of the pod. The variation of seed viability in pods was more determined by genetic differences in local varieties. The average seed viability from three parts of the pods was highest for seeds originated from local varieties of Lumajang and Sampang. Therefore, it is recommended that the seeds of both local varieties can be mixed to be used for optimum cowpea cultivation.

The abundance of glycerol as the side product of biodiesel has motivated researches on glycerol utilization as a feedstock for more valuable products. This research presents the possibility of producing polyester (glyptal), which is a widely used coating material, from glycerol by esterification using phthalic anhydride. Esterification reaction of phthalic anhydride and glycerol to produce glyptal can be catalyzed by Lewis acid provided by either homogeneous or heterogeneous catalyst. This study compared the performance of activated zeolite as heterogeneous catalyst in the esterification of glycerol and phthalic anhydride with the performance of p-toluenesulfonic acid (PTSA) as homogeneous catalyst. The reactions were carried out in laboratory scale batch reactor. The kinetics was modeled using Step Growth Polymerization Model. The rate constant obtained from experimental data fitting on the model was correlated with temperature by Arrhenius equation. Both activated zeolite and PTSA exhibited Arrhenius behavior. Based on the comparison of the Arrhenius constants of the reaction catalyzed by each of the two different catalysts, PTSA performed better in term of lower activation energy. Nevertheless, this result did not suggest that activated zeolite was failed. The activated zeolite was successful to make the reaction happen. To reach the same performance as the homogeneous PTSA, the activated zeolite needs to be improved with respect to its cation exchange capacity and also the operational consideration such as the amount of zeolite added per volume of reaction and the intensity of mixing to minimize the diffusion resistance surrounding the zeolite particles.

Published: November 2019

Isolation of inulin from starch generally is done by extraction method. The size of the material to be extracted will affect the extraction process performance. In laboratory scale, the size reduction was done with a knife and the separation of starch from tubers was done by juicer. Temperature fluctuations during the extraction process would affect the yield of inulin, hence juicers and waterbath were found ineffective for larger scale. This research was aimed to design an extractor equipped with agitator blades for size reduction and a temperature controller. Extractor performance was investigated by evaluating agitation time (60-150 minutes), distance between agitator blades on the shaft (5 and 7 cm), number of the agitators, (1, 2, and 3 blades) against the fineness of cut material, starch and inulin content. The results showed that the highest fineness of the samples was achieved at a distance of agitator blade of 7 cm, with 3 agitator blades and agitating time of 150 minutes. The highest yield of starch was 11.7% at size reduction time of 120 and 150 minutes using 3-blades agitator and the distance of 7 cm. The content of crude inulin obtained were by using the extractor was 2.206% and 2.213% by using the water bath. The difference of inulin content was 0.007% so it suggests that the extractor designed in this study can be used on inulin production in larger scale. The efficiency of the extractor was 85%.

The purpose of this study was to determine the effect of NaCl on the properties of gelatin from Lizardfish (Saurida spp.) scales. The cleaned scales was demineralized using a mixture of NaOH 0.5% and NaCl (0- 0.8%), at various temperatures (45, 65, 86oC) and time (30, 60, 90 and 150 minutes). The obtained samples was determined by ash content, pH, the lightness and moisture content. Addition of NaCl reduced the ash, pH and moisture content but increased the whiteness. Gelatin physical properties increased inline with NaCl concentration. Extended demineralized period gave a positive effect on ash, pH and moisture content but opposite effect was observed in the lightness and physical properties. Extended demineralization periods in high temperature reduced gelatin quality. The highest gel strength was found at demineralization for 150 min at 65oC using a combination of NaOH 0.5% and NaCl 0.8%. At this condition, the gelatin has 10%, 1,7%, 248 bloom, and 7,1 cP of moisture content, ash, gel strength and viscosity, respectively, which fulfil SNI 06.3735.1995.

Sawdust is one of the abundantly lignocellulosic materials in the world. Sawdust is considered promosing for ethanol production, because it contains mainly lignin, hemicellulose, and cellulose. The drying process was applied to pretreat sawdust to make its degradation process easier. Biodegradation of sawdust was conducted by enzymatic hydrolysis using cellulase. The volume of cellulase in the hydrolysis substrate was varied from 5 to 9% v/v. The sugar concentration produced by enzymatic hydrolysis of sawdust every 1 h was recorded as well as its fractal kinetics analysis. Fermentation using yeast in 5 days was also performed to convert sugar hydrolysate to ethanol. Optimal sugar concentration in hydrolysate obtained was about 0.15 mol/L with cellulase volume of 9% v/v and its ethanol concentration was about 0.059% v/v. Fractal kinetics models by Kopelman and Valjamae which can quantitatively describe enzymatic hydrolysis of sawdust using cellulase were used. However, the result of this study indicated that, at high enzyme volume (9% v/v), Valjamae model was more suitable than Kopelman. The fractal exponent value (h) was about 0.667 and the rate constants (k) were about 0.44, 0.53, and 0.58 1/h at the enzyme volume of 5, 7, and 9% v/v. Thus, it can be concluded that enzyme volumes significantly effect rate constants.

Two-stage anaerobic fluidized bed is an innovation in anaerobic digestion technology intended to handle liquid waste with high organic loading and complex substrate. The process is based on separation between acidogenic/acetogenic and methanogenic processes. The first stage is anaerobic process to convert substrate (represented as soluble chemical oxygen demand/sCOD) into volatile fatty acids (VFA). The second stage is methanogenic process to convert VFA into biogas. This study aimed to separate acidogenic/acetogenic and methanogenic processes by means of limited injection of air (micro-aeration) and inoculum selection. Micro-aeration was introduced in acidogenic/acetogenic stage because the relevant microbes were facultative so that the obligate anaerobic methanogens will be suppressed. On the other hand, the methanogenic reactor was kept completely anaerobic to ensure methanogenic dominance over acidogenic/acetogenic ones. Two sources of inoculums were used in this study, i.e. anaerobically digested biodiesel waste and anaerobically digested cow manure. Both inoculums were taken from active biogas reactor treating biodiesel waste and cow manure, respectively. Experiments were run in batch reactors treating palm oil mill effluent (POME) as the substrate for the acidogenic/acetogenic reactor. After the reaction in the first stage reached the minimum substrate concentration, the content of the reactor was used as the substrate for the methanogenic reactor as the second stage. Routine measurements were taken for sCOD and VFA concentrations, biogas production, and methane concentration in the biogas. Results confirmed that micro-aeration maintained good performance of acidogenic/acetogenic process, which was indicated by peaks in VFA accumulation, while suppressing methanogenic activities as no methane produced in this stage. Digested biodiesel waste was superior inoculum to be compared to digested cow manure with respect to sCOD removal. In the methanogenic stage, digested biodiesel waste also performed better as inoculum as it led to higher VFA conversion, higher biogas production rate, and higher methane content in the biogas.
