Microbialite taphonomy and biogenicity: new insights from NanoSIMS
Authors: WACEY D. , GLEESON D. , KILBURN M. R. 
Published: June 2010

AbstractWe here show that nano‐scale mapping of elements commonly utilized in biological cycles provides a promising new additional line of evidence when evaluating the extent of the contribution of biology to microbialites. Our case study comes from Lake Clifton in Western Australia, a unique environment where living domical and conical microbialites occur in close proximity to ≤4000‐year‐old fossilized equivalents. The outer margins of a partially lithified, actively growing Lake Clifton microbialite are characterized by abundant filamentous cyanobacteria within a loosely cemented aragonite matrix. Nano‐scale chemical maps have been successfully matched to specific morphological features such as trichomes, sheaths and putative extracellular polymeric substances (EPS). A suite of elements (C, O, Mg, N, Si, S) is concentrated within cyanobacterial sheaths, with carbon, magnesium, nitrogen and sulfur also enriched within trichomes and putative EPS. Calcium distribution highlights the sites of aragonite mineralization. In contrast, the fossilized Lake Clifton microbialite contains only rare, extensively degraded cyanobacterial filaments, the mean diameter of which is <50% of the living equivalents. Nevertheless, nano‐scale chemical maps can again be matched with morphological features. Here, poorly preserved filamentous microfossils are highlighted by enrichments in nitrogen and sulfur. Magnesium is no longer concentrated within the filaments, instead it co‐occurs with calcium and oxygen in the calcite cement. Extension of this study to a ∼2720‐million‐year‐old stromatolitic microbialite from the Tumbiana Formation of Western Australia shows that similar nano‐scale signals, in particular nitrogen and sulfur enrichments, are characteristic of stromatolite laminations, even when morphological microfossils are absent. The close similarities of nano‐scale elemental distributions in organic material from modern and ancient microbialites show that this technique provides a valuable addition to the morphological investigation of such structures, particularly in non‐fossiliferous ancient examples.

Published: June 2010

AbstractThe detection of the spatio‐temporal extent of inundation resulting from the floods in 2004 and 2007 in Bangladesh has been studied using time‐series MODIS surface reflectance data. Flood inundation maps were developed from vegetation and land water surface indices derived using surface reflectance. The inundation map developed using MODIS data was compared with a corresponding RADARSAT image, where both images refer to the satellite‐based remote‐sensing data. The estimates show a strong correlation with the inundation area derived from the RADARSAT products (coefficient of determination of R2: 0.96). The paper shows that it is possible to study flood dynamics by assessing inundation and recession patterns and to perform flood assessments similar to the high‐resolution (50 m) microwave satellite, RADARSAT‐based flood assessments using products derived from MODIS 500 m imagery. MODIS has advantages over microwave satellite because it has a high observational frequency and these data are available free of cost. We have concluded that this is a useful method to assess the extent of the temporal floods in the People's Republic of Bangladesh.

AbstractObjective:  Systemic lupus erythematosus (SLE) as a chronic autoimmune disease has a worldwide distribution. There is a wide variation in the natural history of SLE among different ethnic and geographic groups. The aim of this study was to show the manifestations of SLE in Iranian patients.Methods:  The study was on manifestations of SLE according to the database of the Rheumatology Research Center (RRC), Tehran, Iran, on registered patients during the period of 1976 to 2009.Results:  A total of 2280 SLE patients (2052 female and 228 male) were studied. The female : male ratio was 9 : 1 and the mean age at presentation was 24.4 ± 10.4 years. Prevalence of manifestations included: musculoskeletal (83.2%), cutaneous (81.1%), renal (65.4%), neuropsychiatric (23.4%), pulmonary (21.5%), cardiac (17.2%), and hematologic (66.4%) symptoms. There was positive antinuclear antibodies in 86.4% and anti‐DNA in 82.3% of patients. Overlap syndrome and positive family history with other autoimmune diseases were detected in 7.6% and 3.4% of patients, respectively.Conclusion:  In our patients the prevalence of cutaneous involvement was similar to those of nearby countries (with similar climate). Renal involvement was seen more than some other countries especially more than European countries, while other manifestations (such as hematologic and joint involvement) were similar to European countries (with similar ethnicity). We may conclude that genetic and/or climatic factors may lead to different presentations of lupus.

AbstractObjective:  To identify the clinical picture of Behcet’s disease in a large cohort of patients (6500) in Iran, over a period of 35 years, and compare them with other large series from around the world.Methods:  Patients with Behcet’s disease from all over Iran were seen in the Behcet’s Disease Research Unit by a multidisciplinary team (rheumatologists, dermatologists, and ophthalmologists). Diagnosis was based on ‘expert opinion’. Data were collected on a standardized data sheet (105 items), and stored in an electronic database. Data were updated at each follow‐up.Results:  Male to female ratio was 1.22 : 1.00. The mean age at onset was 26 years ± 11.3. The frequency of symptoms were: oral aphthosis 97.3%, genital aphthosis 64.6%, skin manifestations 64.9% (pseudofolliculitis 54.5%, erythema nodosum 22.5%, other lesions 7%), pathergy phenomenon 52.5%, ophthalmologic manifes‐tations 56.8% (anterior uveitis 41.2%, posterior uveitis 44.9%, retinal vasculitis 32.1%), joint manifestations 37.4% (arthralgia 17.2%, monoarticular arthritis 7.6%, oligoarthritis 16.8%, ankylosing spondylitis 2%), neurological manifestations 3.8% (central manifestations 3.5%, mononeuritis multiplex 0.3%), gastrointestinal manifestations 7.4%, vascular involvement 8.3% (phlebitis 5.7%, superficial phlebitis 2.2%, large vein thrombosis 1.1%, arterial thrombosis 0.154%, aneurysm 0.5%), epididymitis 4.7%, cardiac involvement 0.6%, and pulmonary involvement 0.9%. Sedimentation rate was normal in 46.5% of patients. Abnormal urine sediment was detected in 12.2%. HLA‐B5 was present in 53.3% and HLA‐B51 in 47.9% of patients.Conclusion:  Behcet’s disease is mainly seen in young people. The most frequent symptoms are mucocutaneous, ocular and joint manifestations. Comparison with large series did not show major differences.

Published: June 2010

ObjectivesAcoustic neuroma is a benign tumour accounting for approximately 6–10% of all intracranial tumours and occurs mainly in patients aged ≥50 years. Our aim was to investigate a wide range of occupational exposures, individual occupational titles and socioeconomic status (SES) as potential risk factors for acoustic neuroma.MethodsWe conducted a population-based case–control study of 793 acoustic neuroma cases identified through the Swedish Cancer Registry and 101 762 randomly selected controls. Information on SES and occupation was obtained from censuses and linked to job-exposure matrices. Logistic regression was used to estimate ORs and calculate 95% CIs.ResultsAn increased OR was seen for mercury exposure <10 years before the reference year (OR 2.9; 95% CI 1.2 to 6.8), and a more modest association for benzene exposure (OR 1.8; 95% CI: 1.0 to 3.2) ≥10 years before the reference year. We observed a threefold increased risk for females working as tailors and dressmakers ≥10 years before the reference year, and a more than threefold significantly elevated OR for those working as truck and conveyor operators <10 years before the reference year. We found no convincing evidence that SES is related to disease development.ConclusionWe observed an increased risk of acoustic neuroma associated with occupational exposure to mercury, benzene and textile dust. Men working as truck and conveyor operators <10 years before the reference year had the highest increased risk of acoustic neuroma, but it is unclear what in those occupations might contribute to disease development. Our study also suggested an association between acoustic neuroma and being a class teacher or policeman. However, these findings should be further investigated to exclude the possibility of detection bias.
Exposure to metal welding fume particles and risk for cardiovascular disease in Denmark: a prospective cohort study
Authors: Ibfelt Else , Bonde Jens Peter , Hansen Johnni 
Published: June 2010

ObjectivesTo study welding fume particles in relation to cardiovascular diseases.MethodsIn 1986, 10 059 male metal workers in 75 welding companies were sent a questionnaire about their welding experience and lifestyle (83.3% response rate). Of these, 5866 were available for analysis and had ever welded at baseline. Information on exposure to welding fumes after 1986 was obtained by individual linkage to the National Pension Fund. Lifelong exposure to welding fume particles was estimated from a job–exposure matrix based on more than 1000 welding-specific measures of fume particles. Hospital contacts for cardiovascular disease were obtained from the Danish National Patient Registry by individual linkage. The nine disease outcomes considered were acute myocardial infarct (AMI), angina pectoris, other acute ischaemic heart diseases, chronic ischaemic heart disease (CHD), cardiac arrythmias, cardiac arrest, heart failure, cerebral infarct, arterial embolism and thrombosis. The cohort was followed up from baseline until the end of 2006.ResultsWhen the incidence of each of the nine cardiovascular outcomes among welders was compared with 5-year age- and calendar year-specific male national rates, the number of observed cases significantly exceeded that expected for AMI (standardised incidence ratio, 95% CI) (1.12, 1.01 to 1.24), angina pectoris (1.11, 1.01 to 1.22), CHD (1.17, 1.05 to 1.31) and cerebral infarct (1.24, 1.06 to 1.44). Internal comparisons of the cohort with adjustment for tobacco smoking, alcohol and hypertension medicines showed a significantly increasing hazard rate ratio for CHD and non-significant increases for AMI, angina pectoris and cerebral infarct with increasing exposure to particles.ConclusionsThis study supports the hypothesis that exposure to welding processed particles increases the risk for cardiovascular disease.
Optimising sampling strategies: components of low-back EMG variability in five heavy industries
Authors: Trask Catherine M , Teschke Kay , Morrison Jim , Johnson Peter , Koehoorn Mieke 
Published: June 2010

BackgroundDirect/ measurement of work activities is costly, so researchers need to distribute resources efficiently to elucidate the relationships between exposures and back injury.MethodsThis study used data from full-shift electromyography (EMG; N=133) to develop three exposure metrics: mean, 90th percentile and cumulative EMG. For each metric, the components of variance were calculated between- and within-subject, and between-group for four different grouping schemes: grouping by industry (construction, forestry, transportation, warehousing and wood products), by company, by job and by quintiles based on exposures ranked by jobs within industries. Attenuation and precision of simulated exposure–response relationships were calculated for each grouping scheme to determine efficient sampling strategies.ResultsAs expected, grouping based on exposure quintiles had the highest between-group variances and lowest attenuation, demonstrating the lowest possible attenuation with this data.ConclusionThere is potential for grouping schemes to reduce attenuation, but precision losses should be considered and whenever possible empirical data should be employed to select potential exposure grouping schemes.
ANALYSIS OF THE T-POINT–HOPF BIFURCATION WITH ℤ2-SYMMETRY: APPLICATION TO CHUA'S EQUATION
Authors: ALGABA ANTONIO , FERNÁNDEZ-SÁNCHEZ FERNANDO , MERINO MANUEL , RODRÍGUEZ-LUIS ALEJANDRO J. 
Published: June 2010

The aim of this work is twofold — on the one hand, to perform a theoretical analysis of the global behavior organized by a T-point–Hopf in ℤ2-symmetric systems; on the other hand, to apply the obtained results for a numerical study of Chua's equation, where for the first time this bifurcation is considered.In a parameterized three-dimensional system of autonomous differential equations, a T-point is a point of the parameter space where a special kind of codimension-two heteroclinic cycle occurs. A more degenerate scenario appears when one of the equilibria involved in such a cycle undergoes a Hopf bifurcation. This degeneration, which corresponds to a codimension-three bifurcation, is called T-point–Hopf and has been recently studied for a generic system. However, the presence of ℤ2-symmetry may lead to the existence of a double T-point–Hopf heteroclinic cycle, which is responsible for the appearance of interesting global behavior that we will study in this paper.The theoretical models proposed for two different situations are based on the construction of a Poincaré map. The existence of certain kinds of homoclinic and heteroclinic connections between equilibria and/or periodic orbits is proved and their organization close to the T-point–Hopf bifurcation is described. The numerical phenomena found in Chua's equation strongly agree with the results deduced from the models.
Spatially Variable Advection Correction of Radar Data. Part II: Test Results
Authors: Shapiro Alan , Willingham Katherine M. , Potvin Corey K. 
Published: June 2010

Abstract
The spatially variable advection-correction/analysis procedure introduced in Part I is tested using analytical reflectivity blobs embedded in a solid-body vortex, and Terminal Doppler Weather Radar (TDWR) and Weather Surveillance Radar-1988 Doppler (WSR-88D) data of a tornadic supercell thunderstorm that passed over central Oklahoma on 8 May 2003. In the TDWR tests, plan position indicator (PPI) data at two volume scan times are input to the advection-correction procedure, with PPI data from a third scan time, intermediate between the two input times, that is used to validate the results. The procedure yields analyzed reflectivity fields with lower root-mean-square errors and higher correlation coefficients than those reflectivity fields that were advection corrected with any constant advection speed.
Revisiting the Definition of the Drag Coefficient in the Marine Atmospheric Boundary Layer
Authors: Foreman Richard J. , Emeis Stefan 
Published: June 2010

Abstract
A new functional form of the neutral drag coefficient for moderate to high wind speeds in the marine atmospheric boundary layer for a range of field measurements as reported in the literature is proposed. This new form is found to describe a wide variety of measurements recorded in the open ocean, coast, fetch-limited seas, and lakes, with almost one and the same set of parameters. This is the result of a reanalysis of the definition of the drag coefficient in the marine boundary layer, which finds that a constant is missing from the traditional definition of the drag coefficient. The constant arises because the neutral friction velocity over water surfaces is not directly proportional to the 10-m wind speed, a consequence of the transition to rough flow at low wind speeds. Within the rough flow regime, the neutral friction velocity is linearly dependent on the 10-m wind speed; consequently, within this rough regime, the new definition of the drag coefficient is not a function of the wind speed. The magnitude of the new definition of the neutral drag coefficient represents an upper limit to the magnitude of the traditional definition.

Published: June 2010

Abstract
A novel 1,2,3-triazolyl-linked 8-hydroxyquinoline (8-HQ) dimer, as a selective turn-on fluorescent sensor for Cd2+ was efficiently synthesized from the “click” reaction and gave weaker fluorescence in protic solvents and water-based mixture solvent (CH3CN/H2O = 5/95, v/v). This sensor showed highly selective turn-on fluorescence for Cd2+ over Zn2+ within a broad pH range in aqueous solution (CH3CN/H2O = 5/95, v/v).

Introduction of a Highly Photodurable and Common-laser Excitable Fluorescent Amino Acid into a Peptide as a FRET Acceptor for Protease Cleavage Detection
Authors: Taki Masumi , Yamazaki Yoshito , Suzuki Yuto , Sisido Masahiko 
Published: June 2010

Abstract
Synthesis and photochemical properties of a benzoacridone-containing fluorescent amino acid (badAla) which is photodurable and excitable by widely applicable 488 nm lasers was described. The amino acid carries a relatively small fluorophore that shows absorption around 450–500 nm, emission above 500 nm with a high fluorescence quantum yield (0.65), and relatively long fluorescence lifetime (17 ns). BadAla can be used in solid-phase peptide synthesis without any precaution. A peptide-containing badAla was used to measure caspase activity via fluorescence resonance energy transfer (FRET).

Rhetoric in industrial design
Authors: De Castro Martins Secca Ruivo Maria Ins 
Published: June 2010

Based on some of the current proposals interpreting users as the centre of creation in design (Norman, Jordan or Krippendorff), this article raises the question as to what the author defines as the conceptual possibilities and impossibilities (ponderables and imponderables) of industrial
design. It explores possible interpretations between the rhetoric world of increasingly competitive and economy-oriented markets and the rhetorical artifices that can be used by the industrial designer in order to accomplish the functional and emotional requirements of products (transformed
into a dream come true for the user). In this approach (and through the visitation of some rhetorical phenomena of consumerism underlying the current social, economical and behavioural context of developed countries) the author underlines the intention behind actions of marketing, design,
management and mainly economy-oriented policies that guide those countries responsible for the cyclical creation, in the user, of self-identification with a new necessity: attaining a greater happiness through the consumption of a given product. Linked to this phenomenon, there is the framing
of several possible balance strategies, for example: the satisfaction of needs of companies/markets and the careful and sensitive suppression or super-suppression of user-consumer needs.
Within this issue, and by resorting to the general notion of rhetoric in design and specifically
to the notion of biomorphological rhetoric applied to design, emphasis is drawn to the importance nature may have to industrial design as an inspiring entity of project methodological praxes, which are both efficient from a commercial standpoint and from a functional-emotional
standpoint for the user.
In short, considering the above mentioned scope of limitation of different contexts where the new rhetorical-semantic dimension of design is established, this article proposes that the functional-emotional humanization of solutions developed by designers are a result
of the harmonization between the subjectivity inherent to professional ethical deontological values, considering the human-user being, and the intrinsic objectivity of strategic-profitable values supporting producing companies, considering the human-user being. This is because (in the author's
perspective), today, more than in the past, both actions must always function as a whole.
