Binding of polyphenols to plant cell wall analogues - Part 2: Phenolic acids

Bacterial cellulose and cellulose-pectin composites were used as well-defined model plant cell wall (PCW) systems to study the interaction between phenolic acids (PA) derived from purple carrot juice concentrate (PCJC) and PCW components. Significant PA depletion from solution occurred, with pure cellulose initially (30 s-1 h) absorbing more than cellulose-pectin composites in the first hour (ca 20% cf 10-15%), but with all composites absorbing similar levels (ca 30%) after several days. Individual PAs bound to different relative extents with caffeic acid > chlorogenic acid > ferulic acid. Extrapolation of data for these model systems to carrot puree suggests that nutritionally-significant amounts of PAs could bind to cell walls, potentially restricting bioavailability in the small intestine and, as a consequence, delivering PAs to the large intestine for fermentation and metabolism by gut bacteria.

Sublethal Exposure to Phosphine Decreases Offspring Production in Strongly Phosphine Resistant Female Red Flour Beetles, Tribolium castaneum (Herbst)

The red flour beetle is a cosmopolitan pest of stored grain and stored grain products. The pest has developed resistance to phosphine, the primary chemical used for its control. The reproductive output of survivors from a phosphine treatment is an important element of resistance development but experimental data are lacking. We exposed mated resistant female beetles to 0.135 mg/L of phosphine for 48 h at 25°C. Following one week of recovery we provided two non-exposed males to half of the phosphine exposed females and to half of the non-exposed control females. Females that had been exposed produced significantly fewer offspring than non-exposed females. Females that remained isolated produced significantly fewer offspring than both exposed females with access to males and non-exposed controls (P<0.05). Some females were permanently damaged from exposure to phosphine and did not reproduce even when given access to males. We also examined the additional effects of starvation prior to phosphine exposure on offspring production. Non-exposed starved females experienced a small reduction in mean offspring production in the week following starvation, followed by a recovery in the second week. Females that were starved and exposed to phosphine demonstrated a very significant reduction in offspring production in the first week following exposure which remained significantly lower than that of starved non-exposed females (P<0.05). These results demonstrate a clear sublethal effect of phosphine acting on the female reproductive system and in some individuals this can lead to permanent reproductive damage. Pest population rebound after a fumigation may be slower than expected which may reduce the rate of phosphine resistance development. The results presented strongly suggest that phosphine resistance models should include sublethal effects. © 2012 Ridley et al.

Structure, energetics and diffusion properties of isomers of trimethyl benzene in beta zeolite: Uptake and Monte Carlo simulation study

A Monte Carlo study along with experimental uptake measurements of 1,2,3-trimethyl benzene, 1,2,4-trimethyl benzene and 1,3,5-trimethyl benzene (TMB) in beta zeolite is reported. The TraPPE potential has been employed for hydrocarbon interaction and harmonic potential of Demontis for modeling framework of the zeolite. Structure, energetics and dynamics of TMB in zeolite beta from Monte Carlo runs reveal interesting information about the diameter, properties of these isomers on confinement. Of the three isomers, 135TMB is supposed to have the largest diameter. It is seen TraPPE with Demontis potential predicts a restricted motion of 135TMB in the channels of zeolite beta.Experimentally, 135TMB has the highest transport diffusivity whereas MID results suggest this has the lowest self diffusivity.

Dingoes at the doorstep: Preliminary data on the ecology of dingoes in urban areas

Wild carnivores are becoming increasing common in urban areas. In Australia, dingoes exist, in most large cities and towns within their extended range. However, little empirical data is available to inform dingo management or address potential dingo–human conflicts during urban planning. From GPS tracking data, the nine dingoes, predominately juvenile and female, we tracked lived within 700 m of residential homes at all times and frequently crossed roads, visited backyards and traversed built-up areas. Home range sizes ranged between 0.37 km2 and 100.32 km2. Dingoes were mostly nocturnal, averaging 591 m/h between dusk and dawn. Juvenile and adult dingoes spent up to 19% and 72% of their time in urban habitats. Fresh scats from most areas surveyed tested positive to a variety of common zoonoses. These data suggest dingoes are capable of exploiting peri-urban areas and might contribute to human health and safety risks, the significance of which remains unknown.

Job performance ratings: The relative importance of mental ability, conscientiousness, and career adaptability

According to career construction theory, continuous adaptation to the work environment is crucial to achieve work and career success. In this study, we examined the relative importance of career adaptability for job performance ratings using an experimental policy-capturing design. Employees (N = 135) from different vocational backgrounds rated the overall job performance of fictitious employees in 40 scenarios based on information about their career adaptability, mental ability, conscientiousness, and job complexity. We used multilevel modeling to investigate the relative importance of each factor. Consistent with expectations, career adaptability positively predicted job performance ratings, and this effect was relatively smaller than the effects of conscientiousness and mental ability. Job complexity did not moderate the effect of career adaptability on job performance ratings, suggesting that career adaptability predicts job performance ratings in high-, medium-, and low-complexity jobs. Consistent with previous research, the effect of mental ability on job performance ratings was stronger in high- compared to low-complexity jobs. Overall, our findings provide initial evidence for the predictive validity of employees' career adaptability with regard to other people's ratings of job performance.

Hintakäsitykset funktionaalisista elintarvikkeista ja euron käyttöönoton vaikutus

Työn tavoitteena oli tutkia kuluttajien hintakäsityksiä funktionaalisista elintarvikkeista sekä euron käyttöönoton vaikutuksia niihin. Teoriaosassa tarkasteltiin funktionaalisen elintarvikkeen käsitettä ja sen hintaan liittyviä kysymyksiä erikoistuotteen näkökulmasta sekä kuluttajan hintakäsityksen muodostumisessa tärkeää osaa näyttelevää referenssihintaa ja sen vaikutuksia sekä teoreettista taustaa, erityisesti adaptaatiotasoteoriaa. Lisäksi tarkasteltiin euron mahdollisia vaikutuksia referenssihintaan sekä referenssihinnan roolia kuluttajan hintakäsityksen muodostumisessa. Työn empiirinen osa koostui kahdesta kyselytutkimuksesta, jotka suoritettiin ennen euron käyttöönottoa joulukuussa 2001 ja sen jälkeen huhtikuussa 2002. Ensimmäiseen kyselyyn vastasi 182 ja toiseen 135 vastaajaa. Vastaajat olivat pääkaupunki- sekä Hämeenlinnan seudulta. Tutkimuksen kohteena olevat tuotteet olivat Gefilus®-piimä ja -mehut, ja kohderyhmänä niiden käyttäjät. Tutkimuksen empiirisessä osassa selvitettiin funktionaalisten elintarvikkeiden käyttö- ja ostotottumuksia sekä mielipidettä niiden hintatasosta suhteessa terveysvaikutuksiin ja tavallisiin elintarvikkeisiin. Referenssihintoja tutkimuksen kohteena oleville tuotteille tutkittiin sopivana, korkeimpana ja alhaisimpana hyväksyttävänä hintana.Euron vaikutuksia hintakäsityksiin tutkittiin vastausten eroissa kyselyjen välillä. Euron käyttöönoton aiheuttamia referenssihintojen muutoksia tarkasteltiin hintaherkkyysmittari avulla. Lisäksi tutkittiin euron käyttöönoton aiheuttamia muutoksia ostokäyttäytymisessä. Faktori- ja ryhmittelyanalyyseja käytettiin vastaajien ryhmittelyyn. Funktionaalisia elintarvikkeita pidettiin vastaajien joukossa kalliina suhteessa niiden terveysvaikutuksiin tai tavallisten, ei-funktionaalisten, tuotteiden hintaan. Tutkimuksen kohteena olleiden tuotteiden, Gefilus®-piimän ja -mehujen, hintatasoa pidettiin myös kalliina. Gefilus®-mehujen hintaa pidettiin yleisesti liian kalliina. Euron käyttöönotto aiheutti muutoksia vastaajien referenssihinnoissa. Euron käyttöönoton voitiin havaita vaikuttaneen kuluttajien hintakäsityksiin siten, että hinnat vaikuttivat aikaisempaa halvemmilta. Lisäksi euron käyttöönotto oli vaikeuttanut hintojen arviointia. Lähes kaikki vastaajat olivat sitä mieltä, että euron käyttöönoton jälkeen hinnat olivat nouseet. Euron käyttöönotto oli myös lisännyt pankkikortin käyttöä maksuvälineenä käteisen sijaan.

Structural Studies of Analgesics and Their Interactions. VIII.* Rotational Isomerism and Disorder in the Crystal Structure of Meelofenamie Acid

Meclofenamic acid, C I4HIICI2NO2, probably the most potent among analgesic fenamates, crystallizes in the triclinic space group P1, with a = 8.569 (5), b = 8.954(8), c -- 9.371 (4) A, ct = 103.0 (2), fl -- 103.5 (2), y = 92.4 (2) ° , Z = 2, D m = 1.43 (4), D c = 1.41 Mg m -3. The structure was solved by direct methods and refined to R = 0.135 for 1062 observed reflections. The anthranilic acid moiety in the molecule is nearly planar and is nearly perpendicular to the 2,6-dichloro-3-methylphenyl group. The molecules, which exist as hydrogen-bonded dimers, have an internal hydrogen bond involving the imino and the carboxyl groups. The methyl group is disordered and occupies two positions with unequal occupancies. The disorder can be satisfactorily explained in terms of the rotational isomerism of the 2,6-dichloro-3-methylphenyl group about the bond which connects it to the anthranilic acid moiety and the observed occupancies on the basis of packing considerations.

The status of entrepreneurship education in Australian universities

Purpose The purpose of this paper is to provide an analytical overview of the current state of entrepreneurship education (EE) in Australia; placing emphasis on programs, curricula and entrepreneurship ecosystems. Design/methodology/approach The authors performed a contextual review of the literature by delineating entrepreneurship education programs, the entrepreneurial ecosystem and EE learning and teaching. The review was enhanced by a systematic collection of data from higher education institutions web sites, depicting the prevailing situation of entrepreneurship programs, courses, subjects and their ecosystems. Findings A number of interesting findings emerged from this study. From a curricular perspective, Australian universities offer 584 subjects related to entrepreneurship. This includes dominance at undergraduate level, representing 24 minors/majors and specializations in entrepreneurship. In total, 135 entrepreneurship ecosystems were identified. Research limitations/implications This paper presents findings from university web sites and as such requires introspection to validate individual university offerings. Practical implications The study provides the status of EE in Australia, and may guide academic and policy decision makers to further develop entrepreneurship initiatives. Originality/value This paper provides the first analytical overview of EE in Australia and paves the way for further evaluation.

The Structure of Monosodium Phosphoenolpyruvate

CDH406P-.Na +.H20 , M r = 208.0, is monoclinic, Cc, a = 11.423 (2), b = 23.253 (5), c - 6.604 (1) A, fl = 123.63 (1) °, U = 1460.6 A 3, D x =. 1.89 Mg m -a, Z = 8, 2(Mo Ka) = 0.7107 A, p(Mo Ka) = 0.44 mm -~, F(000) = 840. Final R = 0.063 for 1697 reflections.The two crystallographically independent molecules of phosphoenolpyruvate (PEP) (A and B) are almost mirror images of each other, the mirror being the planar enolpyruvate group. The torsion angle C(3)-C(2)- O(1)-P(1) is 122.6 in A and -112.0 ° in B, in contrast to -209.1 ° in PEP.K. The enolic C(2)-O(1) has a partial double-bond character [1.401 (A), 1.386A (B)]. The high-energy P~O bond (1.595 and 1.610A) is comparable to that in PEP.K (1.612 A). Na(1) has six nearest neighbours while Na(2) has only five. The Na + ions are involved in binding only the phosphates of different molecules, in contrast to the K ÷ ion in PEP. K, which binds to both the phosphate and carboxyl ends of the same molecule. The planar carboxyl groups stack on each other at an average distance of 3.2 A instead of forming hydrogen-bonded dimers usually found in carboxylate structures.

2,6-Lutidine-N-oxide complexes of rare-earth bromides

2,6-Lutidine-N-oxide (LNO) complexes of rare-earth bromides of the composition $$MBr_3 .(LNO)_{4_{ - n} } .nH_2 O$$ wheren = l for M = La, Pr, Nd, Sm, Gd, Ho, Er; andn = 0 for M = Y have been prepared and characterised by analyses, conductance and infrared data. Infrared spectra of the complexes indicate that the coordination of ligand to the metal ion takes place through the oxygen of the ligand, and the water molecule in the complexes present is coordinated to the metal. A coordination number of seven has been suggested to all the rare-earth metal ions.
