description: The fungus-cultivating termites constitute part of diverse termite fauna in Africa that include
Macrotermes, Odontotermes, Microtermes among others. Mutualistic relationship between lineages offungi (Agaricomycetes, Lyophyllaceae, Termitomyces) and the fungus cultivating termites remains obscure.The complex association between the Termitomyces symbionts and termites is due the
distinct organization strategies of members in the genus Termitomyces and other micro-symbionts
including Xylaria/Pseudoxylaria within the termite mounds. We have reviewed the diversity, properties,and ecological significance of the genus Termitomyces in Africa as a continent,which harbours diverse species of flora and fauna. The organization of these fungal species within the mounds is exceptional and leniently forms a distinct micro-environment that supports diverse species of micro-organisms.Enzymatic assays have also revealed that Termitomyces species play significant roles in balancing the ecosystem within the termite mounds. The review has established sixteen Termitomyces species that have been recently published in Africa. In comparison to the diverse fungus-farming termites, this is an indication of limited findings. The diversity of Termitomyces species is still underexplored despite its interesting symbiotic interactions; hence, newly emerging methods to improve its classification andmutualistic association should be explored.

Publisher: name: Swinburne
Year: 2024

description: In this paper, a state space approach for computing the inverse of a general single-input single-output linear periodically time-varying filter is proposed. The inverse of the filter is derived by first constructing the inverse of an LPTV filter. The result is then extended to obtain the inverse of the IIR filter. Compared with existing approaches using other techniques, the proposed approach is quite straightforward, hence, can reduce the computational complexity.

Publisher: name: VITIS - Journal of Grapevine Research
Year: 2015

description: In two consecutive years and under different environmental conditions, leaf gas exchange, sap flow and trunk diameter were measured to estimate transpiration of grapevine. Daily maxima of sap flow were lower than estimations obtained by gas exchange measurements. Sap flow was delayed with regard to variation of irradiance. For irrigated plants the correlation between transpiration rates of single leaves as determined by gas exchange and instantaneous sap flow was high (r2=0.84). However, the correlation of sap flow with the total daily water consumption was even higher (r2=0.98) and close to 1:1. At various water states, leaf photosynthetic rate was also correlated with sap flow (r2=0.78); the correlation coefficient increased to r2=0.91 when the daily balance was compared. Plant growth, estimated from linear variable displacement transducers was closely related to the daily sap flow.

Developmental changes of primary processes of photosynthesis in sun- and shade-adapted berries of two grapevine cultivars
Creators: name: Düring, H.
name: Davtyan, A.
Publisher: name: VITIS - Journal of Grapevine Research
Year: 2015

description: Light utilisation and thermal dissipation of field-grown sun- and shade-adapted berries of cvs Kerner (white) and Portugieser (red) were investigated during berry development by determining chlorophyll fluorescence parameters. In stages I and H of berry development for both cultivars the maximum quantum yield of photochemical energy conversion of dark-adapted berries (Fv/Fm) was close to the maximum (0.75-0.80). It decreased significantly in sun- and shade-adapted berries of cv. Kerner two weeks after veraison indicating damage of photosystem 11 (PSII) during ripening. When at veraison anthocyanins accumulated in the skin of berries chlorophyll fluorescence of cv. Portugieser berries could no longer be determined. In both cultivars the linear electron transport rate at light saturation (ETRmax) increased in stage I and reached maxima in stage 11, sun-adapted berries showing higher rates than shade-adapted. After high values in stage I non-photochemical quenching at light saturation (NPQmax) decreased in light- and shade-adapted Kerner berries in stage 11 indicating a lowering of the thermal dissipation efficiency. The pool size of the xanthophyll cycle pigments diverged significantly in sun- and shade-adapted berries during their development: under clear, warm and dry weather conditions in shade-adapted berries the xanthophyll pool size decreased to low levels, while in sun-adapted berries it increased to maximum values shortly before (cultivar Kerner) or at veraison (cultivar Portugieser) and subsequently declined. Unripe, sun-adapted berries of both cultivars showed a transient decline of the xanthophyll pool size during a rain period suggesting pool size adjustment to changes of ambient conditions in the longer term. It is concluded that unripe, sun-adapted berries are better adapted to high light than shade-adapted berries due to their higher capacity of photosynthetic energy consumption and thermal energy dissipation; at the onset of ripening these photoprotective mechanisms appear to loose importance.

A bestatin primes grapevine cells for augmented elicitation of the hypersensitive-like cell death and associated defense responses by methyl jasmonate
Creators: name: Repka, V.
Publisher: name: VITIS - Journal of Grapevine Research
Year: 2015

description: Localized treatment of grapevine (Vitis vinifera L. cv. Limberger) leaves with bestatin, an inhibitor of some aminopeptidases in plants and animals, augmented the sensitivity for methyl jasmonate-induced hypersensitive-like response. Enhanced resveratrol accumulation was associated with potentiated activation of genes encoding phenylalanine ammonia-lyase (PAL). The augmentation of PAL gene induction was proportional to the length of pretreatment with bestatin, indicating time-dependent printing of the cells. Exogenously supplied bestatin also potentiated other characteristic elicitor-induced short- and long-term defense responses in cell suspensions of grapevine including strong medium alkalinization and the production of reactive oxygen species (ROS), sequentially followed by defense gene activation and phytoalexin accumulation. Bestatin therefore appears to be exerting its effects close to the level of transcriptional control of defense-related genes, where it might inhibit a regulatory protease. Strikingly, the ability of bestatin to potentiate grapevine PAL gene elicitation and resveratrol accumulation, emphasizes an important role for defense response potentiation in acquired plant disease resistance.

Agenda-Setting in ABC Australia's China Tonight: A Content Analysis of China-related Coverage
Creators: name: Miao Jianwei*
Publisher: name: Zenodo
Year: 2025
Subjects: Agenda-setting theory, China Tonight, ABC (Australian Broadcasting Corporation), China–Australia media relations, Media framing, Content analysis.

description: Abstract: This study investigates how Australia’s national broadcaster ABC set the media agenda for China-related issues through its program China Tonight from 2021 to 2023. Drawing on first-level agenda-setting theory, the research employs content analysis to examine 23 episodes, identifying issue salience and thematic evolution. The findings reveal that the program predominantly focused on social and political topics—such as China’s population policies, education reforms, human rights, and diplomatic tensions—while also gradually incorporating cultural and everyday life issues over time. The thematic shifts across the three years reflect both geopolitical developments and changing audience expectations. The study demonstrates a dual logic in ABC’s reporting, balancing “hard” topics with socially resonant “soft” topics to construct a multidimensional image of China. By highlighting the agenda-setting mechanisms at play, this research contributes to a deeper understanding of intercultural media narratives and offers insights into the dynamics of China–Australia media relations. Limitations and directions for future research are also discussed.

School-trip tourism, in fact, is nontrivial: approx. 92,9M students make more than 100M day trips and 15-20M overnight trips a year. School-trips are planned by secondary schools all over the year, as well as students from HEIs and ACADs travel mainly for learning purposes. Basing on this particular fact, school-trip tourism can effectively contribute to improve arrivals in low-medium season period, meeting the goals of the Calypso initiative. The UN World Tourism Organization (UNWTO) and World Youth Student and Educational (WYSE) Travel Confederation together have documented the growing role that youth and student travel has taken within the global tourism industry over the last decades. More young people travel and do so more frequently and over greater distances than ever before. Building on these premises, EUMillennialsTOUR will create a transnational tourism product for the school-trip tourism market, addressed to secondary schools and High Education Institutes/ACADs, increasing the competitiveness of the EU tourism and capitalizing the shared value of European industrial heritage sites under the paradigm of sustainability, by also complementing national, regional and local policies in the field of creative industries and industrial heritage tourism, contributing to the professionalization of the tourism, cultural and educational workers. The resulting tourism product will also stimulate the young generations to the value of EU industrial heritage sites as memory of our past.

description: The impact of ozonation on the reduction of chlorinated disinfection by-products formation was investigated in 15 full-scale and lab-scale drinking water facilities of Québec (Canada). Total trihalomethanes (TTHM) and the sum of six haloacetic acids (HAA6) were measured after chlorination under uniform formation conditions (UFC). Results showed that before ozonation TTHM and HAA6 average concentrations were 89.4 and 45.3 μg/L, respectively. In full-scale ozonation conditions TTHM-UFC and HAA6-UFC reductions averaged respectively 27 and 32%. After lab-scale ozonation at a O3/C of 1:1, a decrease of only 9% of TTHM was calculated, while for HAA6, reduction was not significantly impacted (30%). For BDOC, average concentrations of 0.13, 0.46, and 0.69 mg C/L were measured before and after and lab-scale ozonation, respectively. Chlorine demand (Cl2D) and immediate ozone demand (IOD) were found to be the most appropriate indicators to evaluate NOM reactivity after ozonation.

description: An approximate image reconstruction method for gantry tiled multi slice computed tomography (MSCT) is presented in this paper, which extends the Feldkamp cone beam reconstruction algorithm to overcome its inaccuracy problem caused by large cone angle. This is done by tilting the reconstructing planes to minimize the cone angle and optimally fitting the spiral segment of the source. It is shown that the image reconstruction performance of the proposed algorithm is superior to that of the Feldkamp reconstruction algorithm. Because a 3D projection data set is employed, the proposed algorithm can use the projection more efficiently than 2D approximate reconstruction algorithms. With the reduced distance from the X-ray source to the reconstruction plane, the maximum pitch value of the proposed algorithm is larger than that of conventional Feldkamp algorithm. The proposed algorithm can archive higher volume coverage speed than Feldkamp algorithm.

description: Resistance of colchicine-induced autotetraploids of four grapevine rootstock cultivars (Riparia Gloire de Montpellier, Rupestris St. George, Couderc 3309 and Kober 5BB) to phylloxera (Daktulosphaira vitifoliae FITCH) was evaluated using the aseptic co-culture technique of root segments and phylloxera in a petri dish, and compared with those of the original diploid and Cabernet Franc (Vitis vinifera L.). None or very few phylloxera nymphs grew to adults on the root of the rootstock cultivars and their autotetrapolids whereas 26.8 % of the eggs grew to adults on the roots of Cabernet Franc. Resistance of Riparia Gloire de Mont-pellier, Rupestris St. George, Couderc 3309 and their autotetraploids to phylloxera was also tested by planting in a phylloxera-infested vineyard and compared with that of Kyoho, a tetraploid table grape cultivar (V. vinifera x V. labrusca Bailey). The formation of galls on the root tips of tetraploid rootstock cultivars was not increased significantly as compared to that on their original diploid plants whereas galls were formed on 52.9% of Kyoho root tips examined. These results show that the autotetraploid rootstock cultivars used in this study had high resistance to phylloxera, thus they were not different from the original diploids.

description: To study changes in carbonyl compounds in Chardonnay and Cabernet Sauvignon wines as a consequence of malolactic fermentation (MLF), wines were fermented by inoculation of commercial strains of Oenococcus oeni, and compared with unfermented (control) wines. Carbonyl compounds were determined by GC/MS analysis on the basis of their O-(2,3,4,5,6-pentafluorobenzyl)-hydroxylamine derivatives after sample preparation on an ion exchange column to remove pyruvic acid. With MLF, marked changes were revealed, particularly with regard to diacetyl, acetoin and aliphatic saturated aldehydes; the presence of unsaturated aldehydes was also revealed. A significant increase in glycoladehyde was observed, which is presumed to be part of a reduction system with glyoxal. Higher acetoin/diacetyl ratios were found in Chardonnay and higher glycolaldehyde/glyoxal ratios in Cabernet Sauvignon.

Robustness Analysis of Multirate Control Systems in the Frequency Domain
Creators: name: Zhang, Cishen
name: Zhang, Jingxin
Publisher: name: Swinburne
Year: 2024

description: This paper analyzes robustness of multirate control systems with fast control sampling rate and slow output measurement rate in the frequency domain. It is shown that the multirate control is characterized by manipulating the system frequency response in high frequency subbands and folding the high frequency subband response to the base frequency band. This amplifies the system loop gain in high frequency subbands leading to deterioration of system robustness stability under the uniform plant model perturbation.

Robustness of discrete periodically time-varying control under LTI unstructured perturbations
Creators: name: Zhang, Jingxin
name: Zhang, Cishen
Publisher: name: Swinburne
Year: 2024

description: This note investigates robustness of linear periodically time varying (LPTV) control of discrete linear time invariant (LTl) plants subject to LTI unstructured perturbations. The note first derives a necessary and sufficient condition for robust stability of an LPTV system subject to LTl perturbations, which is less conservative than the well known small gain condition. It then presents a quantitative analysis on the robustness of LPTV control under LTl unstructured perturbations in comparison with that of LTl control. It is shown that under the normal value of the controller period suggested in the previous literature, the stability margin is deteriorated by LPTV control if LTl uustructured perturbations are considered. Hence LTI control is superior to LPTV control in this respect.

description: Five N-heterocyclic carboxylate based coordination complexes, [Co(L1)2(H2O)2]·2H2O (1), [Cd(L1)2(H2O)2]·2H2O (2), [Co(L2)(H2O)3] (3), [Ni(L2)(H2O)3] (4) and [Cu2(L2)2(H2O)2] (5), have been synthesized and characterized by elemental analysis, IR spectroscopy, PXRD, thermogravimetric analyses and single crystal X-ray crystallography, where HL1 is 2-((5-amino-1H-1,2,4-triazol-3-yl)thio)acetic acid and H2L2 is 2-((5-amino-1-(carboxymethyl)-1H-1,2,4-triazol-3-yl)thio)acetic acid. In these complexes, the hydrogen bonds (H-bonds) play an important role in their packing structures. Complex 1 has nine H-bonds showing a 3D sqc38 topology. Complex 2 has 17 H-bonds exhibiting a 3D hxl network. Complexes 3 and 4 are isomorphic, both of which possess ten H-bonds to present a 3D btc topology. Complex 5 with eight H-bonds forms a 2D sq1 structure. In addition, complex 3 catalyzes the decolorization of methyl orange (MO). Meanwhile, 1, 3 and 5 show certain anticancer activities to inhibit the growth of HepG2 cells.

Publisher: name: Swinburne
Year: 2024

description: This paper presents a quantitative analysis on the robustness of discrete linear periodically time varying (LPTV) control under different perturbations in comparison with linear time invariant control. For unstructured perturbations, it is shown that the system stability margin is definitely deteriorated by LPTV control. For structured perturbations, the paper clarifies the mechanism of LPTV control in stability margin improvement and the side effect of this improvement-deterioration of the stability margin for unstructured perturbations. In a unified frequency domain framework, the paper exposes the relevance and conflictions of the previous results on the robustness of LPTV control, and therefore provides a deeper insight into the problem.

Secondo una nuova ricerca della University of Central Lancashire, nelle prime fasi della loro evoluzione i giganti gassosi non hanno una forma sferica, come precedentemente ipotizzato, ma una forma appiattita che ricorda quella di uno smartie. I risultati dello studio, pubblicato su A&A Letters, hanno importanti implicazioni per le osservazioni dirette di giovani pianeti in formazione, suggerendo che il modo in cui essi appaiono al telescopio dipende dall’angolo di visione

description: ABSTRACTTesting programs exist to establish initial estimates of reliability for strategic weapon systems and to determine significant changes in reliability. The methods to determine the appropriate sample sizes are based on one- and two-sample estimates of proportions. There are guidelines that exist that provide specific methods to determine sample sizes for strategic weapons systems. The methods used are considered to be quite conservative, and this article investigates alternative approaches for both initial and follow-on test sizing for weapon system reliability estimates. The methods are compared through Monte Carlo simulation.
