description: Past applications of biosolids to soils at some locations added higher Cd levels than presently permitted. Cadmium phytoextraction would alleviate current land use constraints. Unamended farm soil, and biosolids amended farm and mine soils were obtained from a Fulton Co., IL biosolids management facility. Soils contained 0.16, 22.8, 45.3 mg Cd kg–1 and 43.1, 482, 812 mg Zn kg–1 respectively with initial pH 6.0, 6.1, 6.4. In greenhouse studies, Swiss chard (Beta vulgaris var. cicla), a Cd-accumulator maize (inbred B37 Zea mays) and a southern France Cd-hyperaccumulator genotype of Noccaea caerulescens were tested for Cd accumulation and phytoextraction. Soil pH was adjusted from ∼5.5–7.0. Additionally 100 rice (Oryza sativa) genotypes and the Ni-hyperaccumulator Alyssum murale were screened for potential phytoextraction use.Chard suffered phytotoxicity at low pH and accumulated up to 90 mg Cd kg–1 on the biosolids amended mine soil. The maize inbred accumulated up to 45 mg Cd kg–1 with only mild phytotoxicity symptoms during early growth at pH > 6.0. N. caerulescens did not exhibit phytotoxicity symptoms at any pH, and accumulated up to 235 mg Cd kg–1 in 3 months. Reharvested N. caerulescens accumulated up to 900 mg Cd kg–1 after 10 months. Neither Alyssum nor 90% of rice genotypes survived acceptably.Both N. caerulescens and B37 maize show promise for Cd phytoextraction in IL and require field evaluation; both plants could be utilized for nearly continuous Cd removal. Other maize inbreds may offer higher Cd phytoextraction at lower pH, and mono-cross hybrids higher shoot biomass yields. Further, maize grown only for biomass Cd maximum removal could be double-cropped.
On numerical and linguistic quantification in linguistic approximation
Creators: name: Kowalczyk, Ryszard
Publisher: name: Swinburne
Year: 2024

description: Interpretation of outputs of fuzzy systems often involves the use of linguistic approximation that assigns a linguistic label to a fuzzy set based on the predefined primary terms, linguistic modifiers and linguistic connectives. More formally linguistic approximation can be considered in the terms of retranslation rules that correspond to the translation rules in explicitation in computing with words such as the simple, modifier, composite, quantification and qualification rules. However most existing methods of linguistic approximation use the simple, modifier and composite retranslation rules only. Although these methods can provide a sufficient approximation of simple fuzzy sets the approximation of more complex ones that are typical in many practical applications of fuzzy systems may be less satisfactory. In particular quantification may be desirable in situations where the conclusions interpreted as quantified linguistic propositions can be more informative and natural. Quantification in linguistic approximation can provide an additional information about the scope of the linguistic labels assigned to a given fuzzy set enhancing the interpretability of the conclusions. This paper presents some aspects of linguistic approximation in the context of the retranslation rules and proposes an approach to linguistic approximation with the use of the quantification rules. Two methods of the quantification in linguistic approximation are considered with the use of the numerical and linguistic quantifiers. These quantifiers are based on the concepts of the non-fuzzy and fuzzy cardinalities of fuzzy sets, respectively. A number of examples are provided to illustrate the proposed approach.

description: Pistacia lentiscus L. is known in some Tunisian forest area by its fixed oil used in traditional medicine as an antiseptic product. This investigation is the first to study the antimicrobial activity of P.lentiscus edible oil and its phenolic extract. Oil was extracted from fruits harvested from six provenances located in Tunisia. The antimicrobial activity was tested using disc diffusion assay and the broth dilution method. Kbouch and Sidi Zid oils were most efficient (p Staphylococcus aureus and Aspergillus niger with an inhibition zone of 9.33 mm. The phenolic extract had the largest spectrum of sensitive microorganisms. The minimum inhibitory concentration and minimum bactericidal concentration results showed that all strains were inhibited by both oil and extract.

description: In high diversity, Just In Time production environments, mixed-model assembly lines aim at producing a large amount of end products that use alternative variants of components used in the assembly process. Therefore, the availability of parts required at the border of the assembly line is critical for the production process. To ensure the availability of parts needed on the line, three line feeding modes are commonly used in practice: line stocking, kitting and sequencing. The relative performance of each mode, in terms of average total operating cost, depends on various factors such as the diversity of components, parts’ physical features (i.e. weight and volume), to name a few. The impact of such parameters on the performance of line feeding modes remains still weakly studied in the literature. Through an empirical approach based on a real case, our study aims at evaluating the average total cost pertaining to each mode. The total cost includes parts preparation before assembly, picking, in-plant transportation and storage costs. A thorough comparative study enables then to characterise situations which make one mode less costly compared with the others. Each situation corresponds to specific values taken by parameters that are considered in the cost formulation.

description: Many effective technologies have been developed and approved for ballast water treatment, and the effectiveness of a process should be evaluated considering its environmental friendliness. The aim of this study was to evaluate the formation and formation mechanisms of bromate (BrO3−) and chlorate (ClO3−) in seawater during ozonation, electrolysis, and a combined (ozonation/electrolysis) process. In seawater ozonation, BrO3− was generated exceeding a 5 mg/L ozone dose despite the high Br− (65 mg/L). The formation of BrO3− and ClO3− by electrolysis depended on the electrode materials where two types of electrodes (IrO2/Ti and Pt/Ti) were used. The combined (ozonation/electrolysis) process generated much higher levels of BrO3− and ClO3− than either individual process. In ozonation or electrolysis, mixed oxidant including HOCl/OCl− and HOBr/OBr− is the main parameter for inactivation, which is called total residual oxidant, TRO. In this study, a predictive model for BrO3− and ClO3− was suggested in terms of TRO formation. This predictive model can recommend allowable TRO (generated by ozonation or electrolysis) for practical applications in seawater treatment.

description: Molecular dynamics simulations of 2-exo and 2-endo norbornyl chlorides are performed in water–acetone mixtures to investigate the role of preferential solvation on the dissociation process of norbornyl chlorides. Increase in the association constants between carbon (C2) and chloride (Cl) of norbornyl chlorides with an increase in mole fraction of acetone supports the experimental data for the corresponding decrease in the rates of solvolysis for both exo and endo norbornyl chlorides. When the mole fraction of water is increased in water–acetone mixtures, acetone molecules are replaced by water molecules around C2 as well as Cl of norbornyl chloride. Preferential solvation by water is analysed using running coordination numbers and excess coordination numbers around C2 and Cl.
On linguistic approximation of subnormal fuzzy sets
Creators: name: Kowalczyk, Ryszard
Publisher: name: Swinburne
Year: 2024

description: Fuzzy systems including fuzzy decision support and fuzzy control systems often provide outputs in the form of subnormal fuzzy sets or fuzzy sets consisting of a number of sub/normal segments. Linguistic interpretation of such outputs by means of linguistic approximation using sets of predefined primary terms, linguistic modifiers and connectives may sometimes produce ambiguous results. It is mainly due to normalization of the approximated subnormal fuzzy sets (or segments) and/or combination of primary terms predefined as normal fuzzy subsets commonly used in the existing linguistic approximation methods. Some aspects of linguistic approximation of such fuzzy sets are discussed and an approach taking into account their subnormality in linguistic approximation is proposed.

description: The reproductive cycle of trochus, Trochus niloticus Linn., from Mermaid Island and Sunday Island in King Sound, Western Australia, was studied as part of the trochus research program carried out at the Northern Territory University, Darwin. The reproductive cycle was established using gonad indices (gonad index, GI, and gonad bulk index, GBI) and histological examinations by sacrificing 15 females and 10 males with basal diameter >60 mm on a monthly basis for one year starting from May 1995. The sex ratio of the trochus population based on the monthly sampling was not significantly different from an expected ratio of 1 male : 1 female (p>0.05) for mature individuals of all size classes. Spearman correlation showed that there was significant correlation (p<0.05) between GI and GBI...
On solving fuzzy constraint satisfaction problems with genetic algorithms
Creators: name: Kowalczyk, Ryszard
Publisher: name: Swinburne
Year: 2024

description: An attempt to solve fuzzy constraint satisfaction problems (FCSPs) with the use of genetic algorithms (GAs) is presented in the paper. A fuzzy relation that represents the degrees of satisfaction of fuzzy constraints in a given FCSP is considered as an objective function of the respective unconstrained optimization problem. A solution of a FCSP such that all constraints are satisfied to the maximal degree is searched for with a GA using the objective function to evaluate the prospective solutions with respect to fuzzy constraint satisfaction. The presented approach is illustrated with an example of a FCSP taking into account different levels of fuzzy granulation influencing GA's performance.
Constraint consistent genetic algorithms

Publisher: name: Swinburne

description: It has commonly been acknowledged that solving constrained problems with a variety of complex constraints is a challenging task for genetic algorithms (GA). Existing methods to handle constraints in GA are often computationally expensive, problem dependent or constraint specific. In this paper we introduce an idea of constraint consistent GA (CCGA) as an attempt to overcome those drawbacks. Constraint handling is based on general constraint consistency methods that prune the search space and thus reduce the search effort in CCGA. Unfeasible solutions are detected and eliminated from the search space at each stage of CCGA simulation process to support genetic operations in producing feasible solutions. A number of well known standard genetic operators are adapted to take advantage of provided constraint consistency during initialization, crossover and mutation. Initial experiments indicate that in the terms of the solution quality and the number of iterations the constraint consistency based approach in CCGA can outperform other constraint handling methods in GA for a number of selected test problems.
Consumer perception of the efficacy and tolerance of glucosamine in joint diseases
Creators: name: Sanders, Marcus
Publisher: name: Charles Darwin University
Year: 2016

description: In Australia, 18% of the population, representing around one in five Australians, experience or are diagnosed with some form of arthritis. This equates to about 3.85 million Australians. The 2008 Crosby Textor Public Opinion Poll (Chong 2012) shows that Australians are more worried about developing arthritis than any other disease. The average cost in terms of arthritis treatment per person per year is $6200, with 61% of arthritis costs borne by the individuals themselves. Glucosamine is an over the-counter complementary medicine marketed for the treatment and relief of various types of arthritis; however, it is only clinically indicated for osteoarthritis. The existing research is conflicting regarding its efficacy. Aim: The aim of this study is to explore consumer perception of the efficacy of, and tolerance for, glucosamine preparations in inflammatory joint diseases. Method: The first component of the study was a qualitative observational survey based, with a 20-question survey administered to members of the community to capture their personal experience of the efficacy and toxicity of glucosamine. Survey questions were based on a visual pain and joint function scale. The second part of the study was an analysis based on an unidentifiable historical patient report to investigate if patients use glucosamine alone or with other medications indicated for the treatment of arthritis, what form of glucosamine salt was used, how long they have been using glucosamine and at what dose. Results: Out of 87 participants (aged 40–84 years, both male and female), 91.9% and 91.7% stated that glucosamine reduced their pain and improved their joint movement respectively. Pain was perceived to be reduced by 3–4 points (out of a possible 5 or more) in 46.5% of participants and 1–2 points’ improvement out of possible 5 or more in joint movement was found in 51.7% of participants. Sixty participants who used glucosamine for six months or more indicated a reduction in their pain and improvement in their joint function by at least 1 point on the scale ranging up to 5 points. The majority of the 60 participants who used glucosamine for six months or more indicated a pain improvement of 3–4 points on the scale. Six participants indicated that glucosamine was not effective in reducing their pain, and four participants indicated that it did not improve their joints function; those participants took glucosamine for less than six months. All others (n=17) had less significant improvement (

description: Ammouliani Island is located in Northern Greece with its exposed rocks belonging to the Serbo-Macedonian Massif of the Hellenic hinterland. Its geology is of great importance because it lies in an area where a striking change in trend of the orogenic fabric from NW-SE to ENE-WSW occurs. For this purpose, a geological map at a scale of 1:10,000 is presented based upon detailed fieldwork and the interpretation of satellite imagery. In addition, special interest has been paid to the tectonic elements of the map units. This detailed mapping results in the definition of a new unit, the Ammouliani Unit, which is placed between the underlying Kerdilion and the overlying Vertiskos Unit of the Serbo-Macedonian Massif. The main features of the Ammouliani Unit are the predominance of leucosomes and the intense migmatization and strong shearing. Three main folding events (F1, F2 and F3) have been defined in the exposed rocks of the island with the first related to intense migmatization and shearing, whereas the last two are progressive to each other and are related to Mesozoic orogenic processes. In addition, NE-ENE striking shear zones were observed with the Ammouliani granite placed parallel to these. The bending of the orogenic fabric from NW-SE to ENE-WSW is younger than the F2 and F3 folding events and is related to Tertiary orogenic (tectono-magmatic) processes due to the convergence between Apulia and Eurasia and the ongoing retreat of the Hellenic subduction zone.
Using constraint satisfaction in genetic algorithms
Creators: name: Kowalczyk, Ryszard
Publisher: name: Swinburne
Year: 2024

description: Existing methods to handle constraints in genetic algorithms (GA) are often computationally expensive or problem domain specific. In this paper, an approach to handle constraints in GA with the use of constraint satisfaction principles is proposed to overcome those drawbacks. Each chromosome representing a set of constrained variables in GA is interpreted as an instance of the same constraint satisfaction problem represented by a constraint network. Dynamic constraint consistency checking and constraint propagation is performed during the main GA simulation process. Unfeasible solutions are detected and eliminated from the search space at early stages of GA simulation process without requiring the problem specific representation or generation operators to provide feasible solutions. Constraint satisfaction is applied actively in GA during initialization, crossover and mutation operations to advantage.

description: In this paper we report the antimicrobial, antiradical and urease inhibitory potential along with photochemical investigation of the crude extracts of Cyphostemma digitatum Lam. Phytochemical screening of both the crude (hot/cold) alcoholic and aqueous extracts of C. digitatum showed the presence of alkaloids, flavonoids, saponins, coumarins, steroids, terpenoids and tannins. The crude methanolic extract (hot/cold) exhibited good antioxidant activity, while the aqueous extract was a weak antioxidant. The crude methanolic extract was found to be more active against Bacillus subtilis, while both the extracts showed moderate antifungal potential, the methanolic crude extract showed good urease inhibitory activity compared with the aqueous crude extract.
Identification and valuation of ecosystem services in the Mount Apo Natural Park, the Philippines, as a basis for exploring the potential of 'payments for environmental services' for the protected area management
Creators: name: Gomez, Aurelia
Publisher: name: Charles Darwin University
Year: 2015

description: Protected areas are the cornerstone of global biodiversity conservation. In the Philippines, the establishment of protected areas is intended to protect biodiversity and other natural resources and values. Protected area management in the Philippines is severely hampered by a funding shortfall. This research was designed to explore whether users and beneficiaries of ecosystem services delivered by one protected area in particular, the Mount Apo Natural Park (MANP), were deriving a consumer surplus and were willing to pay for more environmental services to be delivered in the MANP. The research developed a new understanding of (i) the types of ecosystem services delivered the by the MANP, (ii) value of individual services and the total economic value of the MANP, and (iii) how various payment for environmental services (PES) schemes could add financial resources for the management of the MANP and deliver livelihoods for people living within or adjacent to the MANP. The research adopted a mixed-methods approach, using quantitative research in the form of a contingent valuation survey of resource users and beneficiaries (household water users, climbers and the general public) as the primary method. The survey included qualitative components and extensive consultations were also undertaken with stakeholder representatives. The research provides empirical evidence that users and beneficiaries of the MANP ecosystem goods and services derive unpaid benefits from watershed protection, recreation, and biodiversity conservation. The resulting lower-bound estimate of the total economic value of the MANP was PhP 6482 million (AUD 152.5 million) annually or PhP 118 thousand (AUD 2774) per hectare (in 2010 prices). The research reveals that there is clear potential for PES schemes to generate funds in support of effective management of the MANP. PES schemes for watershed protection or to support recreational values present the greatest potential as payment mechanisms already exist. A PES scheme for biodiversity conservation is likely to be the most challenging to design. Recommendations are provided, based on survey results and international literature, for developing PES schemes to support effective protected area management in the Philippines, in the context of the MANP case study.

Le seuil de perception dans l'eau et en solution modèle de ce composé fortement odorant évoquant le buis avec des nuances plus fruitées de pamplemousse et de fruit de la passion est de l'ordre de quelques ng/1. L'acétate de 3-mercaptohexanol pourrait contribuer significativement à l'arôme variétal des vins de Sauvignon. Identification of 3-mercaptohexyl acetate in Sauvignon wine, a powerful aromatic compound exhibiting box-tree odor Selective extraction of volatile mercaptans present in wines at trace levels, combined with capillary gas chromatographic (GC) analysis using flame photometric detector (FPD) revealed the presence of a previously unreported compound in Sauvignon wine. 3-mercaptohexylacetate was identified by comparison of chromatographic and mass spectrum data with those of the reference compound. This mercapto ester, recently found in passion-fruit, exhibits aroma reminiscent of box tree with grapefruit and passion fruit notes. Its perception threshold in water and model solution is around 2-4 ng/l. 3-mercaptohexylacetate may contribute to the typical varietal aroma of Sauvignon wines.

description: An initiation system comprising activated zinc powder and alkyl bromide is presented for polymerization of vinyl monomers, including vinyl acetate (VAc). The polymerization was demonstrated to be effected in dry conditions at 70 °C and very sensitive to moisture. A radical mechanism was evidenced by spin-trapping method using TEMPO as capping agent and followed block copolymer formation. First order kinetics with respect to concentration of the monomers, methylmethacrylate(MMA), styrene and VAc, relatively long induction periods, and moderate polydispersities (PDI: 1.6–2.4) were determined as typical characteristics of the polymerization system in bulk conditions. The polymerization system was demonstrated to be living, as evidenced by chain extension of the poly (vinyl acetate) (PVAc) with MMA. A ZnBr radical fragment was proposed as key intermediate controlling the chain growth by reversible combination with the active chain ends. The system was also combined with typical copper-mediated atom transfer radical polymerization (ATRP), in which ATRP-growth polystyrene (PS) was directly used as macroinitiator to initiate VAc polymerization yielding block copolymer.

description: Eight experimental model casks were constructed using wood from four oak trees and filled with a 12 % ethanol solution for 200 days. The concentration of ellagitannins was subsequently measured in the solutions and in the inner and outer faces of the cask wood. Only a low proportion of the total ellagitannins was extracted from the wood, and this proportion varied significantly between both different casks and between the eight ellagitannins measured. The two most abundant ellagitannins, castalagin and vescalagin, were the least easily extracted. The concentration of ellagitannins was much lower in the solutions than expected from calculations based on the difference between the inner and outer faces of the wood. This degradation of ellagitannins occurs subsequent to their extraction into solution.

Year: 2024

description: Fuzzy relations (operations and implications) are examined in order to highlight some aspects which may be helpful in choosing proper fuzzy relations in engineering applications. A number or representative fuzzy relations are classified according to a distance measure on the [0,1] interval. The results of these relations are validated qualitatively with respect to the compositional rule of inference and aggregation rules using a singleton fuzzifier. Fuzzy products and implications can give meaningful and reasonable results when used to represent fuzzy relations. However, only products lead to inference results not violating common engineering sense based on the causality principle.

Negotiating flexible agreements by combining distributive and integrative negotiation

Publisher: name: Swinburne
Year: 2024

description: This paper presents an approach to automated negotiation between agents which attempts to combine the advantages of a co-operative value adding approach, with the reality that negotiating agents are also competing. We use the concept of a trusted mediator to facilitate openness regarding what one values, without disadvantaging oneself by revealing sensitive information (such as a reserve price) to the other party. Social science and management literature deals with negotiation between people, and so can be both more complex, and less well defined than automated negotiation between software agents. We take inspiration from the social science literature and develop a computational framework to support negotiating software agents. The framework includes recognition that agents are self interested, and therefore will manipulate the system to their advantage if possible. We include mechanisms to discourage this kind of manipulation in the form of a transaction cost associated with making only small concessions, and a bias in dividing the pie which is the gain from trade which favours the agent who is most 'honest' in making offers.

description: The fractional light interception by different parts of vines trained to various systems was estimated by a modified point-quadrat method using an over-row solar are positioning device equipped with a laser to simulate sunbeam position and angle at any latitude and time of the day. Laser readings were also combined with total vine light interception estimates via a line sensor to calculate the total light intercepted by specific canopy components. At each sampling date (late June and September, corresponding to fruit set and full canopy), type and position of organs were directly detected by the laser beam. Regardless of sampling date, the relative amount of light captured by the renewal-fruiting area (nodes 1 to 6) of simple cordon (SC) and double curtain (GDC) was considerably higher than that of spur-pruned cordon (SPC), whose vegetative area (distal to node 6) received about two-thirds of the incoming light. Relative light interception by main and lateral leaves was rather constant for GDC, thus reflecting the negligible regrowth after topping. By contrast, SC and SPC showed a much stronger response to topping which caused an increase of light interception by laterals (19 % for SC and +21 % for SPC). Frequencies of relative intercepted light by main leaves as a function of node position showed a peak around nodes 6-8, a zone where maximum leaf size is attained in all systems and on all dates. Instead, lateral leaves predominantly exposed to light were within the three basal nodes of the lateral shoots. Estimates of relative and total light for different vine parts at any time during the season as detected by laser scanning can objectively assess important characteristics of grapevine training systems, e.g. cluster and basal node exposure to light.

description: This study reports the chemical composition, antimicrobial activity and antioxidant properties of Psammogeton canescens essential oil (EO) and its main compounds. The EO was obtained from the aerial parts of P. canescens by hydrodistillation and analysed by using GC/MS. The main constituent was β-bisabolene (25%), followed by α-pinene (20%), apiole (15.34%), γ-terpinene (7.34%), p-cymene (5.35%), β-pinene (5.41%), camphene (5.12%), dill apiole (5%), myrcene (4.54%), colchicine (0.56), sylvestrene (0.56%), β-caryophyllene (0.45%), caryophyllene oxide (0.43%), (Z)-β-farnesene (0.32%), cembrene (0.21%), folic acid (0.21%), germacrene D (0.14) and β-sesquiphellandrene (0.13). β-Bisabolene exhibited strong antioxidant activity (14 ± 0.8 μg/mL). The EO of P. canescens was particularly active against Candida albicans and Escherichia coli, with the lowest minimum inhibitory concentration and minimum bactericidal/fungicidal concentration values. In conclusion, these results support the use of the EO and its main compounds for their antioxidant properties and antimicrobial activity.

description: A comparison between two recently developed, PCR-based DNA marker technologies (amplified fragment length polymorphism, AFLP; inverse sequence-lagged repeat analysis, ISTR) was carried out in a group of 19 Vitis vinifera L. accessions, including 13 putative Sangiovese-related grapevines and 6 ''coloured'' ecotypes whose fruits are of importance for conferring intense red colour to the wine. A large amount of polymorphic DNA fragments was revealed by both molecular techniques: 8 different AFLP and 5 ISTR primer combinations generated 264 and 249 polymorphic markers, respectively. Similarity relationships among the accessions were described by cluster analysis. The AFLP analysis revealed the existence of a uniform group for the Sangiovese (SG) ecotypes showing a high degree of genetic relatedness for the members of this cultivar. Among the coloured ecotypes (CLR), variability was more evident. Only the so called Colorino americano ecotype significantly diverged from both groups. ISTR analysis confirmed the genetic dissimilarity of Colorino americano and the existence of the SG and CLR groups, but in addition detected a higher proportion of polymorphism among the Sangiovese accessions compared to AFLP analysis. Sangiovese forte and Saragiolo apparently differed from the other SG-related grapevines in agreement with AFLP results. It is possible that the observed genetic dissimilarity between Sangiovese forte, Saragiolo and other SG-related types could be interpreted by the putative polyclonal origin of many grapevine cultivars, a concept which is generally accepted by the grapevine research community. Both AFLP and ISTR appear to represent innovative, efficient and sensitive molecular tools for investigating genetic diversity among Vitis vinifera ecotypes and for the eventual identification of clones.

description: This study reports the chemical composition, antioxidant and anti-inflammatory properties of Anethum graveolens essential oil and its main compounds. The essential oil was obtained from the aerial parts of the plant by hydrodistillation and analysed by using GC/MS. α-Phellandrene (19.12%), limonene (26.34%), dill ether (15.23%), sabinene (11.34%), α-pinene (2%), n-tetracosane (1.54%), neophytadiene (1.43%), n-docosane (1.04), n-tricosane (1%), n-nonadecane (1%), n-eicosane (0.78%), n-heneicosane (0.67%), β-myrcene (0.23%) and α-tujene (0.21%) were found to be the major constituents of the oil. A. graveolens oil exhibit a higher activity in each antioxidant system with a special attention for β-carotene bleaching test (IC50: 15.3 μg/mL) and reducing power (EC50: 11.24 μg/mL). The TLC-bioautography screening and fractionation resulted in the separation of the main antioxidant compounds, which were identified as limonene (45%) and sabinene (32%). The essential oil and its main compounds exhibited a potent NO-scavenging effect and inhibited the expression of inducible NO synthase.

description: The phytoplasma associated with Australian grapevine yellows (AGY) was compared to other phytoplasma diseases of grapevine using the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analysis. Comparison of eight different Australian isolates suggests that only one type of phytoplasma is associated with this disease. Based on RFLP analysis of the 16S rRNA gene, it was shown that AGY is different from the tomato big bud and sweet potato little leaf phytoplasma strains which are widespread in Australia and that it represents the only other phytoplasma strain recorded in Australia to date. Restriction profiles of grapevine phytoplasmas using Mse I suggest that AGY is unique but most closely resembles those phytoplasmas associated with grapevine diseases in the stolbur group. Sequence analysis of the 16S rRNA gene and adjacent spacer region supports this association. The uniqueness of AGY was confirmed by PCR assays using non-ribosomal primers; the primer pair STOL11f/r2 specific for stolbur phytoplasmas did not result in amplification products in grapevines affected with AGY; the primer pair fMLOl/rMLOl which amplifies a region of the tuf gene from phytoplasmas in the aster yellows cluster, amplified AGY DNA confirming its association within this phylogenetic group. RFLP analysis of the tufPCR product again highlighted a distinction between AGY and other stolbur phytoplasmas occurring in grapevine. The only other phytoplasma in Australia which is in the stolbur group is associated with dieback in papaya, and it has the same RFLP profile of the tuf PCR product as AGY.

A syntax-based approach to reasoning about action and belief update

description: In this paper, we introduce an alternative approach to reasoning about action. The approach provides a solution to the frame and the ramification problem in a uniform manner. The approach involves keeping a (syntax-based) model of the world that is updated when actions are performed. Our approach is similar to the STRIPS system in which formulas are deleted and added as effects of an action. The presented framework however does not suffer from STRIPS' limitations in expressivity.

description: In this work, govaniadine, an alkaloid isolated from Corydalis govaniana Wall. was evaluated for its analgesic activity by writhing and hot-plate tests. Govaniadine did not display any toxic effects in mice up to 20 mg/kg during 24 h assessment study. The acetic acid-induced writhing was significantly reduced by pretreatment with govaniadine in a dose-dependent manner (1.25–5.0 mg/kg, intraperitoneally (i.p.)). Furthermore, molecular docking study has shown that this alkaloid binds the COX-2 enzyme. In the hot-plate test, govaniadine at dose of 2.5 and 5 mg/kg, i.p. displayed analgesic effect at all time points (30, 60, 90 and 120 min). The analgesic effect of govaniadine was significantly antagonised by naloxone administration. Our results demonstrate for the first time that the peripheral and central analgesic effects of govaniadine could be in part related to the involvement of COX-2 activity and by its interaction with the opioid system.
Conversation-based specification and composition of agent services

description: There is great promise in the idea of having agent or web services available on the internet, that can be flexibly composed to achieve more complex services, which can themselves then also be used as components in other contexts. However it is challenging to realise this idea, without essentially programming the composition using some process language such as BPEL4WS or OWL-S process descriptions. This paper presents a mechanism for specifying the external interface to composite and component services, and then deriving an appropriate internal model to realise a functioning composition. We present a conversation specification language for defining interaction protocols and investigate the issue of synchronous and asynchronous communication between the composite service and the component services. The algorithm presented computes a valid orchestration of components, given the interface specification of the desired composite service, interface specifications of available components, and some mapping rules between parameters to deal with ontological issues.
