Further important sensitizers in patients sensitive to fragrances* I. Reactivity to 14 frequently used chemicals

The aim of this study was to determine the frequency of responses to selected fragrance materials in consecutive patients patch tested in 6 dermatological centres in Europe. 1855 patients were evaluated with the 8% fragrance mix (FM) and 14 other frequently used well-defined fragrance chemicals (series I). Each patient was classified regarding a history of adverse reactions to fragrances: certain, probable, questionable, none. Reactions to FM occurred in 11.3% of the subjects. The 6 substances with the highest reactivity following FM were LyralA (2.7%), citral (1.1%), farnesol P (0.5%), citronellol (0.4%), hexyl cinnamic aldehyde (0.3%), and coumarin (0.3%). 41 (2.2%) of the patients reacted only to materials of series I and not to FM. 6.6% of 1855 patients gave a history of adverse reactions to fragrances which was classified as certain. This group reacted to FM only in 41.1%, to series I and FM in 12.0% and to series I only in 7.2%. 74.3% of the 39 patients reacting to both FM and 1 of the materials of series I had any type of positive fragrance history, which was significantly higher in comparison to those with isolated reactions to series I (53.6% of 41), p Ω 0.04. The study identified further sensitizers relevant for patch testing of patients with contact dermatitis, of which LyralA is the most important single chemical.
Characterization of the Microbial Associates of Nematodes Pathogenic to Myrmica rubra

Pristionchus entomophagus is a necromenic nematode commonly associated with dung beetles (Geotrupes spp.) in Europe. Recently, it has been found in Maine emerging from cadavers of M. rubra, an ant native to Europe that is currently established and pestiferous in Maine (Groden and Stack 2011). Laboratory assays inoculating M. rubra with these nematodes caused significant mortality. This study aimed to characterize the bacterial associates of P. entomophagus in order to further understand its pathogenic relationship with M. rubra. Bacterial samples were collected from the cuticle and gut of the nematodes, and the hemolymph of infected hosts. Single spore isolates were established, cultured, and identified using bacterial 16s rRNA gene sequencing. Following BLAST search comparisons of 24 isolate sequences that I obtained, I identified 14 species of bacteria associated with P. entomophagus and its infected hosts. All of these species have been reported as associated with nematodes, insects, the rhizosphere of plants, fungi, or soil. Three species in particular, Serratia marcescens, S. nematodiphila, and S. proteamaculans have all been directly linked to insect mortality in previous studies (Zhang et al. 2009, Nishiwaki et al. 2007, Al Own et al. 2011). Furthermore, S. proteamaculans was found in association with P. entomophagus in the United Kingdom. In comparing the bacterial isolates found in association with the hemolymph of infected hosts to isolates gathered from P. entomophagus, two species, Pseudomonas fluorescens and Delftia sp. were found in both the hemolymph and in association with the external surface of the nematode. The potential mechanism of pathogenicity employed by P. entomophagus is discussed based on the similarities and differences between the species isolated from the nematode and infected hosts.

The antimicrobial activity was determined by disc diffusion method. Out of the four extract used, acetone and ethanol extracts were found to be highly active against Staphylococcus aureus and Bacillus subtilis. Highest in acetone (12 mm) and lowest in ethanol (10 mm). The MIC values were obtained by serial dilution method.
Happy planet, happy people? The impact of pro-environmental behaviour on psychological well-being

The present study was the first (to our knowledge) to experimentally manipulate pro-environmental behaviour in order to assess its causal effects on affect and meaning in life. Participants (N = 343) were randomly assigned to either 1) a group who chose and engaged in a pro-environmental behaviour from a provided list of options; or 2) a control group who found and photographed public art from a provided list of options. The analyses found that there were no significant differences between the pro-environmental group and the control group, and all pre-registered hypotheses were unsupported. Exploratory analyses revealed a within-participants effect, whereby both conditions produced a significant effect on positive and negative affect, as well as meaning in life when compared to participants' average over the last four weeks. However, given that all findings were exploratory, the results should be considered speculative and can serve as direction for future research.

Effects of Scavenging, Entrainment, and Aqueous Chemistry on Peroxides and Formaldehyde in Deep Convective Outflow Over the Central and Southeast United States

Deep convective transport of gaseous precursors to ozone (O3) and aerosols to the upper troposphere is affected by liquid phase and mixed‐phase scavenging, entrainment of free tropospheric air and aqueous chemistry. The contributions of these processes are examined using aircraft measurements obtained in storm inflow and outflow during the 2012 Deep Convective Clouds and Chemistry (DC3) experiment combined with high‐resolution (dx≤3 km) WRF‐Chem simulations of a severe storm, an air mass storm, and a mesoscale convective system (MCS). The simulation results for the MCS suggest that formaldehyde (CH2O) is not retained in ice when cloud water freezes, in agreement with previous studies of the severe storm. By analyzing WRF‐Chem trajectories, the effects of scavenging, entrainment, and aqueous chemistry on outflow mixing ratios of CH2O, methyl hydroperoxide (CH3OOH), and hydrogen peroxide (H2O2) are quantified. Liquid phase microphysical scavenging was the dominant process reducing CH2O and H2O2 outflow mixing ratios in all three storms. Aqueous chemistry did not significantly affect outflow mixing ratios of all three species. In the severe storm and MCS, the higher than expected reductions in CH3OOH mixing ratios in the storm cores were primarily due to entrainment of low‐background CH3OOH. In the air mass storm, lower CH3OOH and H2O2 scavenging efficiencies (SEs) than in the MCS were partly due to entrainment of higher background CH3OOH and H2O2. Overestimated rain and hail production in WRF‐Chem reduces the confidence in ice retention fraction values determined for the peroxides and CH2O.
Iron and manganese effect on soil chemical properties, yield components, and nutritional status of soybean

ABSTRACT In plants, iron (Fe) and manganese (Mn) have many functions, as the transport and electron transference during photosynthesis, and their deficiencies affect the chlorophyll formation, plant growth and grain yield (GY). We carried out two experiments under greenhouse conditions with the aim of determining the influence of Fe and Mn on nutritional status, physiological components, soil chemical properties and yield components of soybean plants. In both experiments, five Fe and Mn rates were used. The GY, shoot dry weight yield (SDWY), the number of grain per pot (NGP), photosynthesis rate (A) and chlorophyll content were influenced by Fe rates, while GY, SDWY, root length and A were influenced by Mn rates. Iron and Mn concentrations in leaves and grains increased with rates of Fe and nutrients. The Mehlich 1 and DTPA-TEA extractants were efficient to determine the Fe and Mn available in the soil.
Microwave-assisted reactions of α-diazoketones with hetaryl and ferrocenyl thioketones*

ABSTRACT Differently substituted hetaryl thioketones react with less reactive diazoketones under microwave (MW) irradiation in toluene solution. After only 2 min, the reactions were complete and, depending on the type of the used diazoketone, α,β-unsaturated ketones, acyl substituted thiiranes or 1,3-oxathioles were obtained as final products. In the case of azibenzil and di(thiophen-2-yl) thioketone, a new type of 1,5-dipolar electrocyclization of the intermediate thiocarbonyl ylide involving a thiophene ring led to a fused sulfur heterocycle. In contrast to hetaryl thioketones, the ferrocenyl analogues decompose under MW irradiation. Alternatively, they react with diazopropanone and 2-diazo-1-phenylethanone in boiling THF in the presence of LiClO4 to give α,β-unsaturated ketones as sole products. In these cases, the reactions require long reaction times. GRAPHICAL ABSTRACT
Degassing of Obsidian Dome rhyolite, Inyo volcanic chain, California

-Research drilling of Obsidian Dome and a nearby feeder dike in Inyo volcanic chain, California, has provided a set of samples that gives us an opportunity to characterize the isotopic signature of rhyolite magma degassing in several near-surface igneous environments. A positive correlation between 8D and wt. % H 2 0 is observed for H 2 0-rich obsidian clasts from tephra deposits and H 2 0-poor samples of the flow erupted from Obsidian Dome; these samples record progressive degassing of the magma. The initial water content and 8D of the magma are estimated to be, respectively, 4.1 wt. % H 2 0 (based on analyses of melt inclusions, HERVIG et al., 1989) and -40 (assuming closed-system degassing prior to the first eruption). Subsequent to the first eruption, variations in 8D and wt. % H 2 0 indicate that degassing became effectively more open-system in character as multiple stages of dominantly closed-system degassing were periodically interrupted by removal of water and melt during successive tephra eruptions. Quantitative modelling of the isotopic effects of vapor loss, including fractionation of hydrogen involving the melt species OH and H 2 0, according to a multi-step scheme, reproduces the observed 8D vs. wt. % H 2 0 trend of the obsidian data. Final-stage, dominantly open-system degassing resulted in 8D values of the obsidian flow as low as -120. Crystallization (devitrification) of the vitreous dome flow and conduit magma yielded no large differences in 8D and 8 18 0 relative to flow obsidian. Water-loss upon crystallization was virtually complete, except for that retained in biotite, and thus no degassing signature was recorded. Low-Ba and high-Ba varieties of rhyolite (VOGEL et al., 1989) have similar 8 18 0 values, but a larger variation in 8D is found for the low-Ba rhyolite. Crystalline rhyolite and, in particular, the glassy margin of the feeder dike record interaction with hydrothermal meteoric waters, as does the hydrogen isotopic composition of basement granitic rocks. Glassy pyroclasts from tephra-filled, sub-horizontal fractures suggest only minor interaction with meteoric water, and much of the hydrothermal alteration probably occurred after emplacement of the dike.
Portulaca oleracea L. (Purslane) extracts display antioxidant and hypoglycaemic effects

Purslane (Portulaca oleracea L.) is a member of the family Portulacaceae. Due to its many health benefits, it is listed in a World Health Organization database. The aim of this work is to investigate the purslane extracts for their chemical profile and bioactivity.In this study, two different solvents (MeOH/H2O and EtOH) were applied to fresh and dried leaves. The extracts were analysed using HPLC-DAD. Phenolic acids (caffeic acid, p-coumaric acid and ferulic acid) and flavonoids (apigenin, kaempferol, luteolin, quercetin, isorhamnetin, kaempferol-3-O-glucoside and rutin) were identified in all samples. Quercetin and p-coumaric acid were the most abundant compounds. Total antioxidant activity was measured by using the ABTS and DPPH tests, and the ferric reducing antioxidant power (FRAP) assay. Hypoglycaemic properties were investigated via the inhibition of carbohydrate-hydrolysing enzymes, α-amylase and α-glucosidase.Fresh hydroalcoholic purslane extract exhibited the highest radical scavenging potential in both ABTS and DPPH test (IC50 values of 52.86 and 66.98 μg/mL, respectively), whereas dried hydroalcoholic purslane extract showed the highest α-glucosidase inhibitory potential (IC50 value of 45.05 μg/mL). Collectively these data show the health properties of this widely consumed salad plant.
Effect of reactive and non-reactive diluents on thermal and mechanical properties of epoxy resin

The effect of reactive (polyethylene glycol) and non-reactive (toluene) diluents on thermal and mechanical properties (tensile strength, hardness and fracture toughness) of diglycidyl ether of bisphenol A epoxy resin (cured by triethylenetetramine) was investigated. The thermal stability and mechanical properties of the epoxy resin modified with reactive and non-reactive diluents at different wt% were investigated using thermo-gravimetric analyser, tensile test, hardness test and single-edge-notched bend test. A minor variation in thermal stability was observed for epoxy resin after addition of polyethylene glycol and toluene at 0.5 wt%; however, further addition of reactive and non-reactive diluents diminished the thermal stability. The addition of 10 wt% of polyethylene glycol in epoxy resin significantly enhances the tensile strength (∼12%), hardness (∼14%) and fracture toughness (∼24%) when compared to that of neat epoxy resin. In contrast, major drop in mechanical performance was observed after addition of toluene in epoxy. Furthermore, fracture surfaces were investigated under field emission scanning electron microscope to elucidate the failure mechanism.
Uranium sorption from aqueous solutions using polyacrylamide-based chelating sorbents

ABSTRACT This article introduces an investigation on the sorption power of two polyacrylamide-based chelating sorbents for uranium ion removal from aqueous solutions. The studied sorption parameters involved pH, contact time, initial uranium concentration, and polymer dosage. The results revealed that a maximum uptake percentage of 65.3 mg/g and 20.1 mg/g for polymers I and II, respectively, could be obtained at pH 4 with 120 min shaking time. Based on isotherm, kinetic, and thermodynamic studies, the sorption process of uranium on the chelating polymers is said to follow Langmuir isotherm model with pseudo second-order mechanism and exothermic nature.
Study of Zooplankton Species Structure and Dominance in Anzali International Wetland

Anzali International wetland is one of the most important places for various organisms such as fishes. Zooplankton are the first consumers in the ecosystem, and they are perfect food for the larvae of fishes. The present study conducted monthly during January 2012 to December 2013 in 9 different stations with zooplankton population and chemical characteristics analysis such as water temperature ranged from 10°C - 22°C, pH determined alkaline nature of the wetland ranged from 7.05 to 9.47, dissolved oxygen was recorded in the range of 3.36 mg/l to 10.51 mg/l, nitrate was ranged between 0.48 - 4.36 mg/l, total phosphates was between 0.15 - 0.67 mg/l, salinity was recorded between 220 - 692 mg/l, TDS was determined between 246 - 1971 mg/l, BOD and COD was also recorded 2 - 36 mg/l and 4 - 74 mg/l respectively. Total 61 zooplankton species were found belonging to 4 groups: Protozoa (22 sp.), Rotatoria (29 sp.), Copepoda (5 sp.) and Cladocera (4 sp.). Rotatoria were found dominating other groups of zooplankton. Kruskal Wallis test showed that there was significant difference between density of zooplankton in different stations, months and seasons (P ≤ 0.05) and significant differences were found between densities of different zooplankton phylum (P ≤ 0.05). The water body is continuously receiving domestic discharge leading to large amount of nutrient inputs and high amount of phosphate and nitrate in the water body indicates that water is eutrophic in nature.
Practice, Power and Place: Southern British Perspectives on the Agency of Early Medieval Rulers’ Residences

This paper advances understanding of rulership over the fifth to the ninth centuries AD, drawing upon a category of elite settlement from southern Britain known as the great hall complex. Guided by a practice-based conceptual framework, we connect these sites with the embodied regimens, rituals, habits, and activities through which rulership was constituted in the early medieval world. Harnessing recent expanded datasets, we generate insights in three key areas. First, by documenting the significant and sustained antecedent occupation attested at great hall sites, we reveal how rulers exploited the complex multiple pasts of these places to advance symbolic and worldly agendas. Second, we reframe understanding of hall construction as a strategy of elite legitimation by focusing attention on the agency of the skilled practitioners who created these innovative architectural statements and, in doing so, recognize these hitherto neglected specialists as ‘crafters’ of rulership. Third, we use proxies from recently investigated great hall complexes to reconstruct the networks of dependency and interaction which enmeshed these centres. A concluding comparative discussion of southern Britain and Scandinavia contributes shared perspectives on rulers’ residences as a prime arena for the orchestration and creative renewal of early medieval sovereignty.

Pengaruh Pelapis Dapat Dimakan dari Karagenan terhadap Mutu Melon Potong dalam Penyimpanan Dingin

Recently, fresh-cut melon consumption has been increasing due to the health benefits. One of methods to reduce the decay of quality by minimal processing of fruits is edible packaging. This method may extend the shelf-life of fresh-cut melon. The objective of this research was to study the effectiveness of the edible coatings and edible films to maintain the quality of fresh-cut melon during storage at 10°C for 6 days. The edible solutions were prepared by dissolving carrageenan of 2%, glycerol of 1%, and tween 80 of 0.2% into aquadest. These solutions were used as coating systems by dipping and wrapping method. Uncoated fruits served as controls. Quality was measured in terms of weight loss, hardness, soluble solids, pH value, and total plate count. The result revealed that for all treatments the value of weight loss, soluble solid content, and total plate count increased during storage whilst hardness, pH, decreased. In terms of microbiological, the coating improved the shelf-life of fresh-cut melon (up to 2 days) compared to the controls.
