description: Liquid–liquid partitioning of Ricinus communis root methanol extract resulted in enrichment of compounds. Purification of the n-hexane fraction led to the isolation and characterisation of two triterpenes: one known compound lupeol (1) and a new diketone pentacyclic triterpene named as erandone (urs-6-ene-3,16-dione) (2), from the plant. Their structures were determined by various spectroscopic techniques. Crude methanolic, enriched n-hexane fraction and isolates at doses 100 mg/kg p.o. exhibited significant (P

description: Spin-orbit interaction (SOI) has been a key tool to steer and manipulate spin-dependent transport properties in two-dimensional electron gases. Here we demonstrate how spin currents can be created and efficiently read out in nano- or mesoscale conductors with time-dependent and spatially inhomogeneous Rashba SOI. Invoking an underlying non-Abelian SU(2) gauge structure we show how time-periodic spin-orbit fields give rise to spin electric forces and enable the generation of pure spin currents of the order of several hundred nano-Amperes. In a complementary way, by combining gauge transformations with "hidden" Onsager relations, we exploit spatially inhomogeneous Rashba SOI to convert spin currents (back) into charge currents. In combining both concepts, we devise a spin transistor that integrates efficient spin current generation, by employing dynamical SOI, with its experimentally feasible detection via conversion into charge signals. We derive general expressions for the respective spin- and charge conductance, covering large parameter regimes of SOI strength and driving frequencies, far beyond usual adiabatic approaches such as the frozen scattering matrix approximation. We check our analytical expressions and approximations with full numerical spin-dependent transport simulations and demonstrate that the predictions hold true in a wide range from low to high driving frequencies.

description: Ocotea puchury-major Mart. is a tree native to the Brazilian rain forest, where it is popularly known as puxurì. In local folk medicine the leaves are used for their sedative, gastroenteric and antireumatic properties. The morphoanatomical study determined those features useful in distinguishing this species from other closely related taxa. Chemical analysis was focused on the study of the volatile oil. Gas chromatography-mass spectrometry analyses indicated safrol as the main compound of the volatile oil (39%). The results confirm and authenticate the use of its leaves in folk medicine. Furthermore, safrol is economically important as the starting material for hemisynthesis of several products. The antimicrobial activity of the essential oil was studied which showed promising activity against environmental microorganisms as well as anti-inflammatory activity.

Subversive frames: Vermeer and Lucio Fulci's 'Sette note in nero'
Creators: name: Heller-Nicholas, Alexandra
Publisher: name: Swinburne
Year: 2024

description: This article investigates the utility of Dutch Master Johannes Vermeer's painting The Love Letter (1669-70) in cult Italian director Lucio Fulci's giallo Sette note in nero (The Psychic, 1977), uncovering a complex relationship that is pivotal to the film thematically and stylistically. While at first glance these two texts may seem random (even anachronistic), Sette note in nero suggests that the use of painting in the horror film potentially offers rich insight into a field that, for orthodox film studies at least, has traditionally been considered incapable of such sophistication. As this analysis will argue, the inclusion of recognisable paintings within a horror film such as this encourages a deeper comprehension that reflect the genre's unique ability to address the mechanics of representation.

description: Adenanthera pavonina is a plant belonging to family Fabaceae. The 95% ethanol extract (EtOH) of the dried powdered leaves of the plant and successive extracts with solvents of increasing polarities were prepared. Fractionation of the successive aqueous EtOH extract on polyamide column and purification of the isolated compounds on Sephadex LH20 led to the isolation of a new methoxy flavonol glycoside named as quercetin 3-O-α-dirhamnopyranosyl-(1‴ → 2″,1″″ → 6″)-β-glucopyranoside-4′-methoxy (1), as well as kaempferol-3-O-α-dirhamnopyranosyl-(1‴ → 2″,1″″ → 6″)-β-glucopyranoside (2), isovitexin (3), quercetin-3-O-rhamnopyranosyl(1‴ → 4″)-β-glucopyranoside (4), quercetin-3-O-β-glucopranoside-4′-O-rhamnopyranoside (5), kaempferol-3-O-α-rhamnopyranosyl(1‴ → 2″)-β-glucopyranoside (6), quercetin-3-O-rhamnopyranosyl(1‴ → 2″)-β-glucopyranoside (7), quercetin-3-O-β-glucopyranoside (8), kaempferol (9) and quercetin (10). Structures of the isolated compounds were established by spectroscopic analysis. Antioxidant activities of EtOH extract, successive extracts and compounds 1 and 2 were evaluated. The ethyl acetate (EtOAc) extract and EtOH extract showed 62.67% and 49.30% free radical scavenging activity, respectively. Cytotoxic activities of the EtOH extract and compounds (1) and (2) were evaluated. The EtOH extract showed a significant cytotoxic activity against Hep G-2 (IC50 = 2.50 μg) as compared with cisplatin (IC50>10 μg).

description: Aerial parts of Microlicia hatschbachii were extracted with hexane, and the extract was evaluated for antimicrobial activity by a broth dilution method. After phytochemical procedures: GC-MS identified aliphatic alkanes, carboxylic acids and methyl esters of long-chain fatty acids; and two diterpenoids [labd-8(17)-en-15-oic acid and labd-8(17),13-dien-15-oic acid] were identified by 1H and 13C NMR. The antimicrobial activity of the hexane extract could be attributed to the presence of labdanes. This identification is the first reported occurrence of labdane diterpenes in the Melastomataceae family.

description: Organizing lessons for heterogeneous learning groups is a challenge for student teachers and novice teachers. To observe and improve classroom management during student teaching, we have developed an assessment tool. The aim of this study is to evaluate and improve the instrument “Scale for Classroom Management in Inclusive Schools (InClass)” with data from 480 student teachers in internships at elementary or special schools in Germany and Austria.
The instrument consists of the three dimensions Adaptive Teaching Scale (ATS),
Relationship Scale (RS), Behavior Management Scale (BMS). Confirmatory factor
analyses revealed good reliable values (CFI = 0.97, TLI = 0.96, RMSEA = 0.06,
SRMR = 0.04) for the three-factor InClass model and could confirm the
theoretically developed scales. The latent correlations were between r = 0.74
and r = 0.63. Teachers in elementary schools also showed latent correlations
between the three dimensions and their assessment of the implementation of
inclusive education in the school ranging from r = 0.51 to r = 0.84. In order to
meet the individual needs of all students, with and without special educational
needs (SEN), novice teachers in particular should be supported in dealing with
heterogeneous learning groups and in using effective classroom management.
Instruments such as InClass help student teachers evaluate and reflect on
instruction and therefore have an important contribution to teacher education.

Dual-mode composite right/left-handed resonator microwave bandpass filters
Creators: name: Fong, Kian Kiong
Publisher: name: Swinburne
Year: 2024

description: This thesis discusses the design and implementation of new dual-mode ring resonator filters using composite-right/left-handed (CRLH) line. Standard lowpass prototype design procedure for a Chebyshev response is employed in the design. Before the resonator filters are designed, the theory of the left and right handed lines are discussed The left handed line which can be modeled as lumped elements LC (inductor and capacitor) iterative networks is considered. The principle of suppression of the second harmonic in CRLH resonators is explained. New CRLH resonator configurations are proposed and implemented. These resonators are analyzed and modeled in a greater detail using circuit modeling technique, which serves as an initial design approach to acquire desirable circuit dimensions before the design layouts are simulated using commercial electromagnetic simulator. Apart from resonator filters, a 4-order Chebyshev bandpass filter with a centre frequency of approximately 0.6GHz is reported. The measured insertion loss and 3dB bandwidth are 1.2dB and 14% respectively. The measurement results showed good agreement with the simulated results. Harmonic suppression is evident and promising by using CRLH line in a ring resonator. In this design, a harmonic occurs at a frequency more than 3 times the centre frequency of the filter.

description: Women writers often experience a conflict between traditional feminine roles and the less traditional role of the female writer. And for those writers, like Anne Sexton, who choose not to choose between roles, the result is conflict. This conflict, recognized by previous critics and evident in Sexton's biography and poetry, results in a domestic imagery expressing this vacillation. In this study, submitted in partial fulfillment for the M. A. degree in English, I provide an in-depth study of Sexton's domestic imagery. I concern myself with two imagery patterns: one, in which the symbolic image's meaning changes randomly with no controlling network: two, in which the symbolic image's meaning is controlled by the kitchen or general domestic environment. I examine this previously underdeveloped imagery pattern and relate it to Sexton's biography—providing new criticism on both the artist and her work.
A particle swarm algorithm for complex quantised problem spaces
Creators: name: Hendtlass, Tim
Publisher: name: Swinburne
Year: 2024

description: The particle swarm algorithm has shown ability to optimize in continuous problem spaces, although it can struggle in problem spaces containing multiple optima. A variant, called Waves of Swarm particles (WoSP), has been shown to be able to handle problem spaces containing multiple optima by sequentially exploring these optima. In this paper the WoSP algorithm is adapted to suit complex quantised problem spaces and applied to a highly constrained problem with many constraint-violating solutions but few constraint-satisfying solutions. The performance obtained is remarkably good and reflects the power of the WoSP algorithm that combines the search ability of particle swarm with that of evolution.

description: From the leaves of Withania somnifera L. Dunal, a new withasteroid named as 5,6-de-epoxy-5-en-7-one-17-hydroxy withaferin A (6) was isolated along with several known compounds, namely 16β-acetoxy-6α,7α-epoxy-5α-hydroxy-1-oxowitha-2,17(20),24-trienolide (1), withanone (2), 16-en-27-deoxy withaferin A (3), 27-deoxy withaferin A (4), withaferin A (5), withanolide D (7) and 27-hydroxy withanone (8). Its structure was determined using spectroscopic methods, namely IR, 1H NMR, 13C NMR, COSY, HMBC and HRMS. Among the known compounds, 16β-acetoxy-6α,7α-epoxy-5α-hydroxy-1-oxowitha-2,17(20),24-trienolide (1) was previously reported from the roots of W. somnifera. Now, it has been isolated from the leaves, as well. The cytotoxic activity of the new steroid was carried out using the MTT assay against a panel of cancer cell lines, namely MCF-7 (breast), WRL-68 (liver), PC-3 (prostate) and CACO-2 (colon). The results showed that the new compound possesses strong cytotoxic activity against liver and breast cancer with an IC50 of 1.0 μg/mL and a moderate activity against colon (IC50 3.4 μg/mL) and prostate (IC50 7.4 μg/mL) cancer cells.

A Differentiated "Dual Track" European Union as a Remedy in Times of Crisis? Debating Habermas, Arendt, and the Theoretical Foundations of Graduated European Integration

Hannah Arendt

description: This EU IDEA paper engages with ideational origins and normative political theories of European differentiated integration. Specifically, it examines a “graduated” policy of integration backed by European-wide referenda in light of the work of Jürgen Habermas and Hannah Arendt – two theorists who are strong advocates of European political integration and constitutionalisation. The paper illuminates justifications, advantages, dilemmas and problems of such differentiated integration with regard to its democratic legitimacy and normative as well as political-theoretical plausibility. While Habermas has proposed and refined this model, Arendt’s radically pro-European ideas can work as a cautioning corrective alerting to the risks and potentially disintegrating effects of differentiated solidarity and integration on the European project. While she would arguably see the democratic legitimation benefits of a European-wide constitutional referendum as suggested by Habermas, her work also points to the risks of further fragmenting or even dismantling the EU altogether.

description: An orientation program may set the scene for what is to follow for commencing students; therefore it is important to ensure that the initial impression a student receives is an appropriate one. In 2005 the orientation program for commencing students at Swinburne University of Technology was redesigned in order to enhance the academic focus. In 2006 the “First Year Academic Orientation Program” was evaluated to assess the success of the transition from a primarily social, to an academic, orientation. Two studies were conducted. Firstly, 799 first year students attending orientation completed an initial evaluation. The evaluation data was used to explore if there were demographic or student status (eg. full vs part time; local vs international) differences regarding the levels to which orientation contributed to: developing a positive attitude to Swinburne; managing university study; and understanding how students can overcome problems. In addition, demographic and student status differences in who would seek assistance for problems and an exploration of the reasons why some would not seek assistance were considered. For the second study, all first year students will be invited to respond to an online “First Year Orientation and Transition Survey” in April-May 2006. Utilising this data, differences between students who did or did not attend the Academic Orientation in terms of adjustment to university; knowledge about university services; positive attitudes towards Swinburne and understanding how to learn in a university environment will be explored. Further, participants who attended orientation will be asked to reflect on the experience and nominate what aspects of Orientation assisted in their first weeks of university. Finally, a qualitative analysis of the written responses to questions about what are the most difficult aspects of becoming a university student and what factors assisted in the adjustment to university life will be presented.

description: One new dihydrochalcone diglycoside has been isolated from the EtOAc fraction of the Egyptian seagrass Thalassodendrin ciliatum (Forsk.) den Hartog, and was identified as 6′-O-rhamnosyl-(1‴ → 6″)-glucopyranosyl asebogenin for which a trivial name Thalassodendrone was established. Furthermore, five known phenolics were isolated and identified as asebotin, quercetin 3,7-diglucoside, protocatechuic acid, ferulic acid and p-hydroxybenzoic acid. The structures of all the isolated compounds were established based on 1D and 2D NMR spectroscopy and high-resolution-mass spectrometer. High-resolution electrospray ionization mass spectra (HR-ESI-MS) were obtained using a JEOL JMS-T100TD spectrometer (JEOL Ltd., Tokyo, Japan). The anti-influenza A virus activity of the isolated new compound and asebotin was evaluated, and the obtained results revealed that the inhibition dose concentration of asebotin was more than that of Thalassodendrone with IC50 = 2.00 and 1.96 μg/mL, respectively, and with cytotoxic concentration (CC50) of 3.36 and 3.14 μg/mL, respectively.

description: The present communication is a first-time report on the analyses of n-alkane profile of epicuticular wax extracted from the mature leaves of Nyctanthes arbor-tristis L. during a calender year. The composition of n-alkanes revealed hentriacontane (n-C31), tritriacontane (n-C33), tetratriacontane (n-C35) and nonacosane (n-C29) as the major constituents with tritriacontane (n-C33) being the dominant constituent. The cumulative percentage of these four odd-numbered alkanes also showed phenological variation being highest during the fruit ripening stage (average value 63.29%) followed by the flowering stage (mean value 60.74%). The values remained moderate on an average of 54.31% for the rest of the year. This study also confirms the xerophytic feature of the plant having higher proportion of longer carbon chain n-alkanes greater than C31 (dominant peaks are of C33 and C35).
On testing effectiveness of metamorphic relations

description: Software testing is a very crucial approach for assuring the quality of the software applications. In this century, software is in use in every sphere of life. Hence, it is very essential to guarantee the correctness of the software functionality to a certain degree. Absence of proper methods to assure the correctness of the software can lead to disasters. Many testing methods have been proposed to select test inputs such that faults in the program can be detected effectively. However, several programs are non-testable due to the so-called 'oracle problem'. The oracle problem means that either there does not exist a mechanism (called 'oracle') to verify the test output given any possible program input, or it is very expensive, if not impossible, to apply the oracle. Detecting faults in a program without the oracle is one of the major challenges of software testing. Metamorphic testing is an innovative approach to alleviating the oracle problem. In metamorphic testing, metamorphic relations are derived from the necessary characteristics of the system under test. These relations can help to generate test inputs and verify the correctness of the test outputs without the need of an oracle. Their effectiveness has a significant role in metamorphic testing. Hence, it is important to select effective metamorphic relations in metamorphic testing. Different metamorphic relations can generate test inputs with different code coverage. Thus, code coverage of generated test inputs can be considered as a characteristic of the corresponding metamorphic relation. This study aims to find out whether the fault-detection effectiveness of a metamorphic relation can be determined by its code coverage. Some case studies have been conducted to analyze the relationship between the code coverage and the fault-detection effectiveness of metamorphic relations. The systems for these studies were selected from different domains that require diverse ranges of metamorphic relations being derived. Moreover, efforts have been given to conduct the research in a platform independent way by choosing the systems from different platforms. Automated mutant generator tools have been used to generate mutants (faulty versions of the system under test) for ensuring non-biased mutants in the experiments. Fault-detection effectiveness of metamorphic relations is calculated by applying metamorphic testing on these mutants. Two basic coverage criteria namely line and branch coverage is taken into considerations. Automated code coverage tools are used to collect coverage data achieved by different metamorphic relations. A certain degree of correlation between the code coverage and fault-detection effectiveness of a metamorphic relation was observed. Code coverage attained by metamorphic relations was found to be a good indicator of the fault-detection effectiveness of these relations. Thus, the selection of metamorphic relations with higher code coverage can help metamorphic testing to become more efficient.

description: The antiradical activity of phytol was evaluated by electron paramagnetic resonance towards hydroxyl radical (√OH), superoxide anion radical (), methoxy radical (√CH2OH), carbon-dioxide anion radical (), as well as towards nitric-oxide radical (√NO) and 2,2-diphenyl-1-picrylhydrazyl (√DPPH) radical. It reduced the production of all tested radicals showing more promising activity against , √CH2OH and √DPPH radicals (56%, 50% and 48%, respectively) in comparison with √NO, and √OH radicals (38%, 23% and 15%, respectively). The antimicrobial activity of phytol was evaluated by the microdilution method against eight bacterial and eight fungal strains. To varying degrees, it was proven to be active against all tested bacteria and fungi (MIC 0.003–0.038 mg/mL and MBC 0.013–0.052 mg/mL, MIC 0.008–0.016 mg/mL and MFC 0.090–0.520 mg/mL, respectively). According to the obtained results, medical foods containing phytol may support development of new therapies for heart disease.

description: Während vor vier Wochen die gewaltsamen Krawalle in Stuttgart für mediale Aufregung gesorgt haben, ist es jetzt deren Aufklärung. Hinter dem Stichwort „Stammbaumforschung” verbergen sich bundesweite Recherchen bei Standesämtern, die die Stuttgarter Polizei anstellt, um einen etwaigen Migrationshintergrund der Tatverdächtigen feststellen zu können.
Was das für die aktuelle Debatte um möglicherweise rassistische Strukturen in den Behörden aussagt und was für gute Polizeiarbeit wichtig ist, bespricht Charlotte Heppner im heutigen Podcast mit TOBIAS SINGELNSTEIN.

description: A new cinnamolyglycoflavonoid 3-cinnamoyltribuloside (1), its precursor tribuloside and two known flavonoid glycosides afzelin and astilbin were isolated from Heritiera littoralis Dryand (Sterculiaceae) ethanolic leaf extract. The dichloromethane leaf extract afforded two known pentacyclic triterpenoids, 3β-taraxerol and friedelin. Extracts and compounds isolated therefrom, with the exception of 3β-taraxerol, exhibited antimycobacterial activity against the non-pathogenic Mycobacterium species Mycobacterium madagascariense and Mycobacterium indicus pranii, with a minimum inhibitory concentration (MIC) 5.0 mg/mL for the crude extracts and MICs in the range of 1.6–0.8 mg/mL for the pure compounds. The extracts together with 3-cinnamoyltribuloside (1), tribuloside and astilbin exhibited 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity. The compounds that showed dual activities could be further evaluated under clinical settings for co-administration with standard anti-tuberculosis drugs.

description: From the leaves of Withania somnifera L. Dunal, a new withasteroid named as 5,6-de-epoxy-5-en-7-one-17-hydroxy withaferin A (6) was isolated along with several known compounds, namely 16β-acetoxy-6α,7α-epoxy-5α-hydroxy-1-oxowitha-2,17(20),24-trienolide (1), withanone (2), 16-en-27-deoxy withaferin A (3), 27-deoxy withaferin A (4), withaferin A (5), withanolide D (7) and 27-hydroxy withanone (8). Its structure was determined using spectroscopic methods, namely IR, 1H NMR, 13C NMR, COSY, HMBC and HRMS. Among the known compounds, 16β-acetoxy-6α,7α-epoxy-5α-hydroxy-1-oxowitha-2,17(20),24-trienolide (1) was previously reported from the roots of W. somnifera. Now, it has been isolated from the leaves, as well. The cytotoxic activity of the new steroid was carried out using the MTT assay against a panel of cancer cell lines, namely MCF-7 (breast), WRL-68 (liver), PC-3 (prostate) and CACO-2 (colon). The results showed that the new compound possesses strong cytotoxic activity against liver and breast cancer with an IC50 of 1.0 μg/mL and a moderate activity against colon (IC50 3.4 μg/mL) and prostate (IC50 7.4 μg/mL) cancer cells.

description: One new dihydrochalcone diglycoside has been isolated from the EtOAc fraction of the Egyptian seagrass Thalassodendrin ciliatum (Forsk.) den Hartog, and was identified as 6′-O-rhamnosyl-(1‴ → 6″)-glucopyranosyl asebogenin for which a trivial name Thalassodendrone was established. Furthermore, five known phenolics were isolated and identified as asebotin, quercetin 3,7-diglucoside, protocatechuic acid, ferulic acid and p-hydroxybenzoic acid. The structures of all the isolated compounds were established based on 1D and 2D NMR spectroscopy and high-resolution-mass spectrometer. High-resolution electrospray ionization mass spectra (HR-ESI-MS) were obtained using a JEOL JMS-T100TD spectrometer (JEOL Ltd., Tokyo, Japan). The anti-influenza A virus activity of the isolated new compound and asebotin was evaluated, and the obtained results revealed that the inhibition dose concentration of asebotin was more than that of Thalassodendrone with IC50 = 2.00 and 1.96 μg/mL, respectively, and with cytotoxic concentration (CC50) of 3.36 and 3.14 μg/mL, respectively.

description: Lippia gracilis Schauer (Verbenaceae) is an aromatic plant widely used in folk medicine in the Brazilian semi-arid region. This work aims at evaluating the anti-microbial activity of essential oils from the leaves of L. gracilis (EOLG) when associated with commercial antibiotics against bacterial resistance. The essential oil obtained by hydrodistillation has 38 chemical constituents with thymol (44.4%), carvacrol (22.2%), p-cymene (6.2%) and α-pinene (5.6%) as major constituents. Microbiological assays were conducted by direct and gaseous contacts. We demonstrated that EOLG has significant synergism with all antibiotics tested. EOLG decreased the minimal inhibitory concentration of the aminoglycosides and improved their zone of inhibition more than 300% against Staphylococcusaureus and 270% against Pseudomonasaeruginosa. These results demonstrate that natural substances present in EOLG have the capacity to modulate bacterial resistance and can be used as an adjuvant therapy against multi-resistant microorganisms such as S. aureus, Escherichia coli and P. aeruginosa.

description: The generation of droplets and their subsequent reaction in the emulsion is critical to the overall kinetics of oxygen steelmaking. High temperature experiments have been performed at McMaster University to study this behavior. The results from this work and other previous studies has formed the basis of a number of physical and chemical models that attempt to describe the critical aspects of droplet behavior in Oxygen Steelmaking. These models include semi-empirical models for predicting droplet generation rate, droplet size distribution and droplet residence time as a function of blowing parameters.

description: Die Präsidentschaftswahl in Polen ist gelaufen, alle haben artig dem Amtsinhaber Andrzej Duda zur zweiten Amtszeit gratuliert, als sei das einfach nur eine demokratische Wahl wie jede andere. Dass sie das nicht war, sondern vielmehr die letzte, nunmehr verpasste Ausfahrt vor dem endgültigen Umbau Polens in eine Autokratie, erfährt man, wenn man mit Leuten wie WOJCIECH SADURSKI redet. Der ist seit vielen Jahren Professor für Rechtstheorie an der Universität Sydney und als solcher ein Gelehrter von Weltruf, aber auch in seinem Heimatland Polen wissenschaftlich und öffentlich sehr präsent – so sehr, dass ihn die Regierungspartei PiS und ihre Verbündeten mit mehreren Gerichtsverfahren überzogen haben. Mit ihm spricht Max Steinbeis in der heutigen Folge unseres Krisenpodcasts über die freie Bahn, die die PiS-Regierung jetzt hat für ihre autoritären Pläne.

description: In our study, the inhibitory activity of curcuminoids towards Plasmodium falciparum thioredoxin reductase (PfTrxR) was determined using LC-MS-based functional assay and showed that only demethoxycurcumin (DMC) inhibited PfTrxR (IC50: 2 μM). In silico molecular modelling was used to ascertain and further confirm that the binding affinities of curcumin and DMC are towards the dimer interface of PfTrxR. The in vitro antiplasmodial activities of curcumin and DMC were evaluated and shown to be active against chloroquine (CQ)-sensitive (D6 clone) and moderately active against CQ-resistant (W2 clone) strains of Plasmodium falciparum while no cytotoxicity was observed against Vero cells.
