description: In this study, essential oils from Voacanga africana seeds at different extraction stages were investigated. In the chemical composition analysis, 27 compounds representing 86.69–95.03% of the total essential oils were identified and quantified. The main constituents in essential oils were terpenoids, alcohols and fatty acids accounting for 15.03–24.36%, 21.57–34.43% and 33.06–57.37%, respectively. Moreover, the analysis also revealed that essential oils from different extraction stages possessed different chemical compositions. In the antioxidant evaluation, all analysed oils showed similar antioxidant behaviours, and the concentrations of essential oils providing 50% inhibition of DPPH-scavenging activity (IC50) were about 25 mg/mL. In the antimicrobial experiments, essential oils from different extraction stages exhibited different antimicrobial activities. The antimicrobial activity of oils was affected by extraction stages. By controlling extraction stages, it is promising to obtain essential oils with desired antimicrobial activities.
Preliminary investigation on use of sewage sludge ash as partly cement replacement in lightweight aggregate concrete

description: This work is a preliminary investigation on major properties for lightweight aggregate (LWA) concrete where sewage sludge ash (SSA) partly replaces the cement. To use SSA in LWA concrete production could lower the CO2 footprint (due to use of less cement) and maybe also give better thermal insulating properties, as the SSA particles are porous and might result in a more porous LWA concrete, the thermal conductivity is however not investigated in this preliminary work. Blocks of LWA concrete were cast. The replacement percentage of cement with SSA was varied: 0, 15, 20, 25, 30, 35 or 45%. From each block, test specimens were drilled (75 mm in both diameter and height). Porosity and compressive strength were measured. It was found that up to 30% SSA did not reduce the compressive strength significantly compared to the reference. These replacement percentages without strength loss are high compared to mortar samples in a previous investigation with SSA from the same incineration plant. The compressive strength of the laboratory produced reference LWA concrete was 1.75 MPa, which was lower than an industrial produced LWA concrete (3 MPa) with the same aggregate, fly ash and cement mass ratio. The mass of water to obtain a LWA concrete mix ideal for casting increased with increasing SSA mass. This due to the porosity and irregular shape of the relatively coarse (d50 95 µm) SSA particles. The water demand for mortar with this SSA replacing 20% cement was increased by 16% compared to the reference without SSA. Thus, the increased need for water in the LWA concrete mixture was as expected. The porosity of the LWA concretes with SSA was higher than the reference, which partly might be due to the high porosity of the SSA particles, revealing that the thermal conductivity was lower. Thus all together the results from this investigation are encouraging in order to continue the research topic.

description: A new anthraquinone, morinquinone, together with 18 known anthraquinones were isolated from the stems of Morinda elliptica Ridl. Their structures were elucidated on the basis of spectroscopic data. They each showed weak inhibitory activity against a susceptible strain of Staphylococcus aureus and a methicillin-resistant S. aureus. Damnacanthal was effective against Microsporum gypseum (MIC 1 μg/mL). Lucidin was active against Entamoeba histolytica (MIC 31.25 μg/mL) and Giardia intestinalis (MIC 7.8 μg/mL).

description: We examine fluctuations of vorticity inside the coherent vortex, appearing as a consequence of the inverse energy cascade in two-dimensional turbulence. Temporal and spacial correlations can be characterized by the pair correlation function. The interaction between the fluctuations leads to non-zero value of the third moment of vorticity. We examine the pair correlation function and the third moment for the model where the pumping is short correlated in time. We find explicit expressions for the Gaussian spacial correlation function of the pumping force. They confirm the general predictions obtained earlier.

description: Measurements of the second-order rate constants and the singlet oxygen absorption capacity (SOAC) values for the reaction of singlet oxygen (1O2) with 23 kinds of food extracts were performed in ethanol/chloroform/D2O (50:50:1, v/v/v) solution at 35 °C. It has been clarified that the SOAC method is useful to evaluate the 1O2-quenching activity (i.e. the SOAC value) of food extracts having two orders of magnitude different rate constants from 3.18 × 104 L g−1 s−1 for tomato to 1.55 × 102 for green melon. Furthermore, comparison of the observed rate constants for the above food extracts with the calculated ones based on the concentrations of seven kinds of carotenoids included in the food extracts and the rate constants reported for each carotenoids was performed, in order to ascertain the validity of the SOAC assay method developed and to clarify the ratio of the contribution of principal carotenoids to the SOAC value.

description: The development of biofouling on finfish aquaculture farms presents challenges for the industry, but the factors underlying nuisance growths are still not well understood. Artificial settlement surfaces were used to examine two possible explanations for high rates of biofouling in Norwegian salmon farms: (1) increased propagule release during net cleaning operations, resulting in elevated recruitment rates; and (2) potential reservoir effects of farm surfaces. The presence of salmon farms was associated with consistently and substantially (up to 49-fold) elevated recruitment rates. Temporal patterns of recruitment were not driven by net cleaning. Resident populations of biofouling organisms were encountered on all submerged farm surfaces. Calculations indicate that a resident population of the hydroid Ectopleura larynx, a major biofouling species, could release between 0.3 × 109 and 4.7 × 109 larvae per farm annually. Such resident populations could form propagule reservoirs and be one explanation for the elevated recruitment pressure at salmon farms.

description: This thesis is an exploration of the links between the notions exemplified in traditional memento mori imagery and the Barthian concept of 'photodeath'. In order to do this I have chosen three contemporary photographers: Christian Boltanski, Joel Peter Witkin and Peter Hujar, in whose work both concepts are manifest in completely different ways. The concepts of memento mori and photodeath are initially discussed separately in some detail. Then, by careful examination of key works in each artist's oeuvre, some critical observations about the nature of both concepts are teased out and explored. The major issues to arise include: what kind of image constitutes a contemporary memento mori, the possible role that photodeath plays in filling the void left by the 20th century denial of death and ritual, and inability of 'photodeath as a phenomenon' to be perceived in the vast number of photographs that assail us daily. These questions are floated throughout the thesis and are not conclusively answered. Certain possibilities are posited however, and their investigation in relation to the work of the three photographers helps to illuminate some of the dark recesses and grey areas that one necessarily encounters when studying the topic of death.

description: Over the past half-century, societal awareness of the detrimental effects of environmental pollution resulting from human activity has increased, and this newfound awakening has given an impetus to research on sustainable construction materials. In particular, research efforts are aimed at developing greener alternatives to portland cement, production of which accounts for 5-10% of global anthropogenic carbon dioxide emissions. Alkali-activated materials, which can be produced almost entirely from industrial by-products, have received considerable interest in this regard. Previous studies on waste-based alkali-activated materials have focused almost exclusively on reuse of solid waste (e.g., fly ash, slag); however, these materials require a highly-concentrated solution of alkali-hydroxides and/or alkali-silicates (typically 8-14M) to catalyze geopolymerization. Although the environmental and economic impact associated with consumption of excessive amounts of virgin alkalis and safety concerns associated with handling highly-alkaline solutions could substantially threaten the scalability of these materials, little work has been aimed at addressing these issues. In the current study, aqueous alkaline waste from industrial caustic washing of hydrocarbons (deemed unsuitable for regeneration or purification processes due to the presence of contaminants) was used as an activating solution for alkaliactivated concrete in place of a conventional virgin alkali solution. The impact of impurities in the waste activator, particularly organics and heavy metals, on mechanical properties, temporal reactivity, mineralogy, and thermal stability of the materials was assessed. Results suggested that this toxic waste stream, for which there are currently few options available for beneficial reuse, could be used to produce alkali-activated materials in place of virgin alkalis without compromising performance.

description: Fibre reinforced concrete (FRC) is a significant achievement of modern construction. Fibres increase the ductile capacity of concrete by enabling it to undergo large deformation before failure. The tensile strength of concrete is increased whereas it would otherwise only be strong in compression. Although FRC has several advantages, the use of steel fibres means it only provides a little contribution towards sustainability; therefore a shift towards new and innovative building materials is an urgent necessity. Most manmade fibres such as steel, synthetic or polymer are industrially manufactured and widely used. Such fibres are nondegradable, non-renewable and expensive. In this research, natural and innovative biodegradable fibres, their preparation and properties and interaction with concrete have been highlighted. Agricultural fibres viz. rice and wheat straw have been used. Rice and wheat are a staple food all over the world. After harvesting the commercial crop there remains huge quantities of straw produced. This straw has generally been seen as a waste product and disposed of since it has a very few economic benefits. One of the major problems of today is the disposal of straw by open air burning and its impact on air pollution has been well documented. Thus the wastage of straw could be minimised if a viable use for it can be found in the construction industry. Being a relatively new material, in this research, the chemical and physical properties of agricultural fibres have been studied. The influence of the addition of fibres in both fresh and hardened concrete has also been investigated. The findings present an interesting insight into agricultural fibres. Due to its easy availability and low-cost, straw has the potential to be a promising bio-based construction material.

description: In recent decades sustainability, carbon footprint and pollution have become significant issues on a global scale. It is widely recognised that the carbon footprint of the construction industry is something that can be reduced and this has led to sustainable materials being used more and more widely to meet emissions targets. Two of these materials are hemp concrete and rapeseed-straw concrete which are bio-composites made of the bio-aggregate, water and a lime binder; in this investigation Vicat prompt natural cement (PNC). The addition of a viscosity modifying agent (VMA) is studied for its effect on the mechanical and transport properties. It was found that the use of a VMA was very effective at countering the two biggest weaknesses of bioaggregates as it reduced the capillarity absorption of the concrete significantly and also greatly increased the compressive strength and modulus of elasticity of the material.

description: Miniaturizing and integrating atomic vapor cells is widely investigated for the purposes of fundamental measurements and technological applications such as quantum sensing. Extending such platforms to the realm of molecular physics is a fascinating prospect that paves the way for compact frequency metrology as well as for exploring light-matter interactions with complex quantum objects. Here, we perform molecular rovibrational spectroscopy in a thin-cell of micrometric thickness, comparable to excitation wavelengths. We operate the cell in two distinct regions of the electromagnetic spectrum, probing $ν_1$+$ν_3$ resonances of acetylene at 1.530$μ$m, within the telecommunications wavelength range, as well as the $ν_3$ and $ν_2$ resonances of $SF_6$ and $NH_3$ respectively, in the mid-infrared fingerprint region around 10.55$μ$m. Thin-cell confinement allows linear sub-Doppler transmission spectroscopy due to the coherent Dicke narrowing effect, here demonstrated for molecular rovibrations. Our experiment can find applications extending to the fields of compact molecular frequency references, atmospheric physics or fundamental precision measurements.

description: The male, female, pupa and larva of a new species of Gelechiidae (Lepidoptera), Locharcha opportuna Moreira and Becker, are described and illustrated with the aid of optical and scanning electron microscopy. A preliminary analysis of mitochondrial DNA sequences including members of related lineages is also provided. The immature stages are associated with galls induced by a species of Palaeomystella Fletcher (Lepidoptera: Momphidae) on Tibouchina sellowiana (Cham.) Cogn. (Melastomataceae), endemic to the Atlantic Rainforest. Larvae are kleptoparasitic, usurping the gall internal space and thereafter feeding on the internal tissues. By determining the variation in population density of both species and following gall development individually throughout ontogeny under field conditions, we demonstrated that the kleptoparasite completes its life cycle inside galls induced by Palaeomystella, where pupation occurs. The variation in seasonal abundance of the kleptoparasite is tied to that of the cecidogenous species, with their corresponding peaks in density occurring sequentially.http://zoobank.org/urn:lsid:zoobank.org:pub:525F6D52-8CE1-47D1-A0D9-78B564DF5565

description: The Central African house snake Boaedon olivaceus has a large distribution from the forests of West Africa to Mabira Forest in Uganda. We sequenced two mitochondrial (cyt b and ND4) and two nuclear (c-mos and RAG1) genes from several populations of B. olivaceus in Central Africa and recovered two highly divergent lineages (Congo Basin and Albertine Rift) attributable to this species. Dating analyses with BEAST suggest the two lineages last shared a common ancestor during the mid-Miocene approximately 12 million years ago, and data from RAG1 showed consistent differences in two amino acids for topotypic Congo Basin B. olivaceus compared to the Albertine Rift lineage and all other examined species of Boaedon. Based on these striking molecular differences and significant differences in ventral scale counts and the number of supralabials contacting the eye, we describe the Albertine Rift lineage as a new species. The recognition of this new species bolsters the importance of the Albertine Rift as an important region for endemism and conservation in continental Africa. Based on the results of our phylogenetic analyses, the poorly known taxon Lycodonomorphus subtaeniatus upembae is elevated to full species status and transferred to the genus Boaedon. http://zoobank.org/urn:lsid:zoobank.org:pub:D0C0E5B5-DBE9-4D21-B5FE-86221DDF60BA
title: The skin sore trial
title: exploring a better treatment option for impetigo in Indigenous children living in remote Australia
titleType: Subtitle
Creators: name: Bowen, Asha
Publisher: name: Charles Darwin University

description: Impetigo is prevalent among Australian Indigenous children living in the Northern Territory. The cause of this endemic skin infection is multifactorial including household overcrowding, poverty, endemic scabies and fungal skin infections, tropical climate, insect bites and minor trauma. Although impetigo is widespread, affecting up to 50% of children in a community at one time, care seeking for treatment of impetigo does not reflect this burden accurately, possibly due to awareness of the painful injection prescribed. A better treatment is needed. This thesis presents the first randomised controlled trial conducted amongst remote living Indigenous Australian children on the treatment of extensive impetigo, and one of the largest impetigo trials worldwide. Methodological gaps were addressed, with studies published on the susceptibility of Streptococcus pyogenes to trimethoprim-sulphamethoxazole (SXT), the transport of impetigo swabs in remote settings and photography protocols for capturing and scoring sores. The principal findings are: 1. Either of two short courses of SXT are non-inferior to standard treatment of impetigo with intramuscular benzathine penicillin G (BPG) – published in The Lancet; 2. S. pyogenes remains the key driver of impetigo in our region; and 3. S. pyogenes is susceptible in vitro to SXT, and SXT is effective in vivo for the treatment of skin infections caused by S. pyogenes. These findings will inform the management of children with impetigo in remote Indigenous communities and have already been incorporated into treatment algorithms and guidelines regionally and nationally. This provides a simple, short-course antibiotic regimen that is palatable, inexpensive and has a low side effect profile, as an alternative to an injection of intramuscular penicillin, which has been the standard of care for more than 20 years. Ongoing surveillance will be needed to understand how this new regimen is utilised and whether widespread use for a common condition will alter antibiotic resistance profiles.

description: We introduce an abstract concept of quantum field theory on categories fibered in groupoids over the category of spacetimes. This provides us with a general and flexible framework to study quantum field theories defined on spacetimes with extra geometric structures such as bundles, connections and spin structures. Using right Kan extensions, we can assign to any such theory an ordinary quantum field theory defined on the category of spacetimes and we shall clarify under which conditions it satisfies the axioms of locally covariant quantum field theory. The same constructions can be performed in a homotopy theoretic framework by using homotopy right Kan extensions, which allows us to obtain first toy-models of homotopical quantum field theories resembling some aspects of gauge theories.

description: This study provides a view of vegetation types dominated by Sesleria species in the Western Carpathians (Sesleria caerulea, S. heufleriana, S. tatrae, and S. uliginosa). We also took into account characteristics/traits such as plant life forms, autochthonous status, endemism, and ploidy level occurring within each relevé in our data set. Altitude and Ellenberg indicator values derived for each relevé were considered as well. Eight vegetation types/formations/habitats were recognized in a data set of 942 phytosociological relevés: (1) synanthropic vegetation, (2) rock fissures and screes, (3) alpine grasslands and heaths, (4) mesic grasslands and pastures, (5) springs and fens, (6) forests, (7) xerophilous shrubland, and (8) high-mountain scrubs (krummholz). Results corroborated and clearly emphasized that Sesleria caerulea has the widest ecological amplitude of all studied species because the species occurred among all studied vegetation types. Sesleria tatrae was present only in several vegetation types occurring from montane to alpine vegetation belts in the highest mountains. Sesleria heufleriana and S. uliginosa were recorded only in low-altitude areas. The difference between them lies mainly in the dampness of each locality. Sesleria heufleriana was frequently found in xerophilous communities, whereas S. uliginosa preferred humid habitats of springs and fens.
A review of the use of sugarcane bagasse ash with a high LOI content to produce sustainable cement composites

description: In recent years, agricultural wastes have been employed as supplementary cementitious materials to produce sustainable cement composites. One of these wastes is the sugarcane bagasse ash (SCBA). The SCBA is available in large quantities in developing countries such as Brazil, India and Mexico, and its disposal is causing different environmental issues. The SCBA has high amounts of silicon, aluminum and iron oxides as major components. Several researchers report that the high amount of these oxides leads to the improvement of the mechanical and microstructural properties of cementing composites containing the SCBA. On the other hand, a high amount of unburned carbon, commonly expressed by the loss on ignition (LOI), could be also present in the SCBA due the inefficient burning process of the bagasse in the boiler in sugar mills. It has been reported that this high LOI content in the SCBA change the water requirement and the rheological properties of cement binders. This might adversely affect the mechanical, microstructural and durability properties of hardened cement composites prepared with this material as well. In order to decrease the LOI content of the SCBA the combination of sieving, grinding and recalcination have been proposed; however, these methods are highly demanding in energy and generate additional contaminants. Sieving is the less energy demanding procedure and appears to be an interesting approach to post-treat the existing SCBA in open damps. Based on the above, this paper presents a review on the effects of the use of SCBA with a high LOI content to manufacture cement composites

description: A taxonomic revision of the genus Alternanthera (Amaranthaceae) in Italy is here presented. Field surveys were carried out during the period 2007–2013. Thirty-six herbaria (both European and American) were consulted as well as extensive literature was analyzed. Four taxa are recognized, all of them to be considered aliens native to South America. Information about nomenclature (accepted names, main synonyms, and types), morphology, chromosome number, alien status (at national and regional levels), occurrence in Italy (at regional and provincial scale), ecology (preferential habitat, phenology, and elevation), taxonomical notes, and Italian vernacular names were provided for each taxon. A diagnostic key was given. For the nomenclatural purposes the generic name Alternanthera and its type was discussed, and the names A. paronychioides and A. pungens were studied and typified (lecto- and neotype, respectively) on specimens preserved at PH and P.

description: This study provides a view of vegetation types dominated by Sesleria species in the Western Carpathians (Sesleria caerulea, S. heufleriana, S. tatrae and S. uliginosa). We also took into account characteristics/traits such as plant life forms, autochthonous status, endemism and ploidy level occurring within each relevé in our dataset. Altitude and Ellenberg indicator values derived for each relevé were considered as well. Eight vegetation types/formations/habitats were recognized in a data set of 942 phytosociological relevés: (1) synantrophic vegetation, (2) rock fissures and screes, (3) alpine grasslands and heaths, (4) mesic grasslands and pastures, (5) springs and fens, (6) forests, (7) xerophilous shrubland, and (8) high-mountain scrubs (krummholz). Results corroborated and clearly emphasized that Sesleria caerulea has the widest ecological amplitude of all studied species, since the species occurred among all studied vegetation types. Sesleria tatrae was present only in several vegetation types occurring from montane to alpine vegetation belts in the highest mountains. Sesleria heufleriana and S. uliginosa were recorded only in low-altitude areas. The difference between them lies mainly in the dampness of each locality. Sesleria heufleriana was frequently found in xerophilous communities, whereas S. uliginosa preferred humid habitats of springs and fens.

description: Two new coordination polymers, [Mn(1,4-BDC)(bimb)0.5]n (1) and [Mn(Hbtc)(bimb)0.5]n (2) (1,4-H2BDC = 1,4-benzenedicarboxylic acid, H3btc = 1,3,5-benzenetricarboxylic acid and bimb = 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene), have been hydrothermally synthesized by reactions of Mn(II) salt with a rigid 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene and varying carboxylate ligands. Complex 1 is a binodal (3,7)-connected 3-D architecture with point symbol (44.617).(63). Complex 2 is a (3,6)-connected 3-D structure with point symbol (3.4.5).(32.42.5.63.72). The luminescent properties of 1 and 2 were investigated in the solid state at room temperature.

description: Dynamic spectrum access is essential for radiocommunication and its limited spectrum resources. The key element of dynamic spectrum access systems is effective spectrum occupancy detection. In many cases, machine learning algorithms improve detection effectiveness. Because of the recent trend of using federated learning, a federated learning algorithm is presented in the context of distributed spectrum occupancy detection. The results of the work presented in the paper are based on actual signal samples collected in the laboratory. The proposed algorithm is effective, especially in the context of a set of sensors with faulty sensors.

Decoding the face: The role of amygdala on facial behavioral cues and a potential new NLP theory.
Creators: name: Lachanas, Vlasios
Publisher: name: Zenodo
Year: 2020
Subjects: NLP, Neuro Linguistic Programming, amygdala, eye movements, EMDR, Saccades

description: Aim: The main aim of this study was to evaluate the Neuro-Linguistic Programming (NLP)
 assumption concerning the eye-movement in terms of cognitive tasks (narrative memory,
 imagination, object recognition and spatial attention). Literature up to now, decline NLP as a
 science based on non-neuropsychological evaluation. Hence, this research clarified cerebrum
 topography via the cognitive tasks and tried to evaluate the role of amygdala on facial
 behaviour cues. Amygdala is responsible for emotional processing and it is part of limbic
 system which via hippocampus activation connects with narrative memory (biographical and
 autobiographical memory). Hippocampus and amygdala triggers Prefrontal Cortex in terms of
 executive functioning (i.e decision making, and morality)
 Methods: Twenty six (13 male and 13 female) students (healthy participants) were recruited
 from city unity and 6 female Multiple sclerosis (MS) patients from Policlinic of Evaggelismos
 hospital. The first picture of Thematic Apperception Test (TAT) was used in order to
 stimulate emotional memories and imagination. More to this, the Edinburgh Handiness
 Inventory was used for clarifying whether participants were right or left handed. All of the
 participants were above 18 and they were right- handed. A video camera was used to record
 the participants’ saccades during the experimental tasks.
 Results: Healthy population results indicated a partial support to NLP claims concerning the
 association between saccades and cognitive tasks. More specific, NLP claims of associating
 right saccades to the imagination task were confirmed, while NLP claims regarding the
 association between left saccades and recall task were not supported. Further, the bilateral
 activation of amygdala was confirmed via right saccades associating to left amygdala,
 reflecting emotional arousal. On the contrary, MS patients’ results confirmed the
 bilateralization of amygdala via the dislocation of emotional functionality. Hence MS patients
 partially confirmed NLP theory, in terms of cognitive tasks, while in terms of constructing a
 story, this research findings were not supportive to NLP theory, as prefrontal cortex seems to
 have a crucial role in this part.
 Conclusion: NLP was neuropsychologically evaluated, and it was indicated the crucial role of
 amygdala and prefrontal cortex. Such results indicate, also the role of saccade reactions in the
 therapeutic alliance. Yet, further research should be done.

description: A new copper(II) complex [Cu(adefovir)2Cl2], where adefovir = adefovir dipivoxil drug, was synthesized and characterized by using different physicochemical methods. Binding interaction of this complex with calf thymus DNA (ct-DNA) has been investigated by multi-spectroscopic techniques and molecular modeling study. The complex displays significant binding properties of ct-DNA. The results of fluorescence and UV–vis absorption spectroscopy indicated that, this complex interacted with ct-DNA in a groove-binding mode, and the binding constant was 4.3(±0.2) × 104 M−1. The fluorimeteric studies showed that the reaction between the complex and ct-DNA is exothermic (ΔH = 73.91 kJ M−1; ΔS = 357.83 J M−1 K−1). Furthermore, the complex induces detectable changes in the CD spectrum of ct-DNA and slightly increases its viscosity which verified the groove-binding mode. The molecular modeling results illustrated that the complex strongly binds to the groove of DNA by relative binding energy of the docked structure −5.74 kcal M−1. All experimental and molecular modeling results showed that the Cu(II) complex binds to DNA by a groove-binding mode.
