Optimal design of 6-DOF eclipse mechanism based on task-oriented workspace
Authors: Lee Donghun , Kim Jongwon , Seo TaeWon 
Published: July 2011

SUMMARYWe present a new numerical optimal design for a redundant parallel manipulator, the eclipse, which has a geometrically symmetric workspace shape. We simultaneously consider the structural mass and design efficiency as objective functions to maximize the mass reduction and minimize the loss of design efficiency. The task-oriented workspace (TOW) and its partial workspace (PW) are considered in efficiently obtaining an optimal design by excluding useless orientations of the end-effector and by including just one cross-sectional area of the TOW. The proposed numerical procedure is composed of coarse and fine search steps. In the coarse search step, we find the feasible parameter regions (FPR) in which the set of parameters only satisfy the marginal constraints. In the fine search step, we consider the multiobjective function in the FPR to find the optimal set of parameters. In this step, fine search will be kept until it reaches the optimal set of parameters that minimize the proposed objective functions by continuously updating the PW in every iteration. By applying the proposed approach to an eclipse-rapid prototyping machine, the structural mass of the machine can be reduced by 8.79% while the design efficiency is increased by 6.2%. This can be physically interpreted as a mass reduction of 49 kg (the initial structural mass was 554.7 kg) and a loss of 496 mm3/mm in the workspace volume per unit length. The proposed optimal design procedure could be applied to other serial or parallel mechanism platforms that have geometrically symmetric workspace shapes.
“Tangible as Tissue”: Arnold Gesell, Infant Behavior, and Film Analysis
Authors: Curtis Scott 
Published: July 2011

ArgumentFrom 1924 to 1948, developmental psychologist Arnold Gesell regularly used photographic and motion picture technologies to collect data on infant behavior. The film camera, he said, records behavior “in such coherent, authentic and measurable detail that . . . the reaction patterns of infant and child become almost as tangible as tissue.” This essay places his faith in the fidelity and tangibility of film, as well as his use of film as evidence, in the context of developmental psychology's professed need for legitimately scientific observational techniques. It also examines his use of these same films as educational material to promote his brand of scientific child rearing. But his analytic techniques – his methods of extracting data from the film frames – are the key to understanding the complex relationship between his theories of development and his chosen research technology.

SUMMARYCampylobacteris the most common known source of human bacterial enteritis in the developed world and poultry is considered the main source. Broilers often become colonized withCampylobacterduring rearing, and then contaminate the farm environment. The objective of this study was to identifyCampylobacter-positive environmental reservoirs on farms, as these pose a risk to broiler flocks becoming colonized withCampylobacter. We considered the temporal aspects of exposure and colonization. A longitudinal study monitored six conventional rearing farms over 2 years. The broiler flocks, catchers' equipment, vehicles, shed surrounds, shed entrance, other equipment, farm entrance, other animals, puddles, dead birds, mains water and drinkers were systematically sampled 2–4 times per flock. A multivariable generalized estimating equation model was used to assess associations between contaminated environmental sites and colonized broiler flocks. The associations were adjusted for confounders and other known risk factors. To further assess temporality of contamination, the sequence of contamination of the different environmental sites and the flocks was established. Contaminated shed entrances and anterooms, contaminated drinkers and shedding ofCampylobacterby other animals such as cattle, dogs, wildlife and rodents were significantly associated with positive flocks. The reservoir of ‘other animals’ was also the reservoir most commonly positive before the flock became colonized. The other sites usually became contaminated after the flock was colonized.

SUMMARYThe burden of respiratory infections is mainly seen in primary healthcare. To evaluate the potential impact of new preventive strategies against respiratory infections, such as the implementation of pneumococcal conjugate vaccines for infants in 2006 in The Netherlands, we conducted a baseline retrospective cohort study of electronic primary-care patient records to assess consultation rates, comorbidities and antibiotic prescription rates for respiratory infections in primary care. We found that between 1995 and 2005, overall registered consultation rates for lower respiratory tract infections had increased by 42·4%, upper respiratory infections declined by 4·9%, and otitis media remained unchanged. Concomitantly, there was a steady rise in overall comorbidity (75·7%) and antibiotic prescription rates (67·7%). Since Dutch primary-care rates for respiratory infections changed considerably between 1995 and 2005, these changes must be taken into account to properly evaluate the effect of population-based preventive strategies on primary-care utilization.
Early-life environment influencing susceptibility to cytomegalovirus infection: evidence from the Leiden Longevity Study and the Longitudinal Study of Aging Danish Twins

SUMMARYHuman cytomegalovirus (CMV) is a common herpesvirus establishing lifelong persisting infection, which has been implicated in immunosenescence and mortality in the elderly. Little is known about how and when susceptibility to CMV infection is determined. We measured CMV seroprevalence in two genetically informative cohorts. From the Leiden Longevity Study (LLS) we selected long-lived sib-pairs (n=844) and their middle-aged offspring and the offspring's partners (n=1452). From the Longitudinal Study of Aging Danish Twins (LSADT) 604 (302 pairs) same-sex monozygotic (MZ) and dizygotic (DZ) twins aged 73–94 years were included (n=302 pairs). Offspring of the long-lived LLS participants had significantly lower seroprevalence of CMV compared to their partners (offspring: 42%vs. partners: 51%,P=0·003). Of 372 offspring living with a CMV-positive partner, only 58% were infected. The corresponding number for partners was 71% (P<0·001). In the LSADT, MZ and DZ twins had high and similar CMV-positive concordance rates (MZ: 90%vs. DZ: 88%,P=0·51) suggesting that shared family environment accounts for the similarity within twin pairs. Our findings suggest that susceptibility to CMV infection – even under continuous within-partnership exposure – appears to be more strongly influenced by early-life environment than by genetic factors and adult environment.
Factors affecting vascular access complications in children undergoing congenital cardiac catheterization
Authors: Roushdy Alaa M. , Abdelmonem Noha , El Fiky Azza A. 
Published: July 2011

AbstractBackgroundComplications at the vascular access sites are among the most common adverse events in congenital cardiac catheterization. The use of small-gauge catheters may reduce these events; however, other factors can contribute to the development of vascular complications.ObjectivesTo determine factors associated with the development of vascular access complications in children undergoing congenital cardiac catheterization.MethodsWe performed a prospective study of 403 patients who underwent diagnostic (62.5%) or interventional (37.5%) cardiac catheterization over a period of 6 months, and analysed the vascular complications during and immediately after the procedure.ResultsThe most common access-related adverse event was transient loss of pulsation (17.6%). Other less common access-related adverse events included subcutaneous haematoma (2%), bleeding (3%), vessel tear (0.2%), and vein thrombosis (0.2%). Patients who had no access-related adverse events had significantly higher age and body weight compared with those who had one or more access problems. Among 81 patients who had vascular access established in unplanned access sites, 30 patients (37%) had lost pulsations. Among the 322 patients who had vascular access established in planned access sites, however, only 41 patients had lost pulsation (13%). In addition, patients who had lost pulsations had significantly longer puncture time compared to those who had normal pulsations (p value 0.01).ConclusionFactors other than sheath size can contribute to access-related adverse events in children undergoing cardiac catheterization. Obtaining vascular access in unplanned access sites and longer puncture times increases the incidence of lost pulsations after catheterization. Younger age and smaller body weight are also associated with significant increase in access-related adverse events.
A PATRON AMONG PEERS: DEDICATIONS TO HAYDN AND THE ECONOMY OF CELEBRITY
Authors: GREEN EMILY 
Published: July 2011

ABSTRACTBetween 1784 and 1809 more than forty composers dedicated works to Haydn, resulting in the largest group of offerings to a single composer in the eighteenth and nineteenth centuries. Whilst Horst Walter has suggested that certain of these works reveal the ways in which composers received Haydn's style, a study of the larger collection of dedications illuminates the broader nature of Haydn's fame and the ways in which other composers and their publishers both contributed to and capitalized on that fame. Making Haydn into a kind of pseudo-patron, the title-pages, advertisements and dedicatory epistles for these works allow for an exchange of various types of capital ranging from the material to the symbolic, ultimately enabling both dedicator and dedicatee to improve their reputations in the eyes of the consuming public.
ALIGNMENT, ABSORPTION, ANIMATION: PANTOMIME BALLET IN THE LOMBARD ILLUMINISMO
Authors: LOCKHART ELLEN 
Published: July 2011

ABSTRACTThis article investigates the theme of statuary animation within pantomime and language reform, particularly in Milan between the 1760s and the 1790s. Its focal point is a little-known work created by Florentine choreographer Gasparo Angiolini for the new Teatro alla Scala in 1782: his didactic ‘philosophical ballet’La vendetta spiritosa, based on theTraité des sensationsby Étienne Bonnot de Condillac (in Venice the work was given asLa vendetta ingegnosa o La statua di Condilliac[sic]). During the last decades of his career, informed by French linguistic theory and by Milanese writers such as the Verri brothers and Cesare Beccaria, Angiolini aimed to create an unmediated music-gestural language that could overcome linguistic and even political boundaries. The project had significant implications for the use of representative sound, both in music and in language. I examine the development of the impulse towards gestural mimesis and through-composition within scores for thedanza parlante, including by Angiolini himself.
HAYDN'S FORGOTTEN QUARTETS: THREE OF THE ‘PARIS’ SYMPHONIES ARRANGED FOR STRING QUARTET
Authors: JONES DAVID WYN 
Published: July 2011

ABSTRACTIn 1787 Artaria, Haydn's publisher in Vienna, issued three versions of The Seven Last Words: the original orchestral version, a quartet arrangement prepared by the composer and a keyboard arrangement sanctioned by him. A year later, in September 1788, Artaria issued three of the recent ‘Paris’ Symphonies, Nos 84, 85 and 86, in an arrangement for quartet. While the quartet version of The Seven Last Words has always been accepted as part of the canon, the three quartet arrangements of the symphonies have been ignored. Sympathetic consideration of a range of evidence, including the bibliographical, historical and text-critical, suggests that Haydn may have been the author of these three quartets.
CloVR-16S: Phylogenetic microbial community composition analysis based on 16S ribosomal RNA amplicon sequencing – standard operating procedure, version 1.0

Published: July 2011

AbstractThe CloVR-16S pipeline employs several well-known phylogenetic tools and protocols for the analysis of 16S rRNA sequence datasets:A) Mothur – a C++-based software package used for clustering 16S rRNA sequences into operational taxonomic units (OTUs). Mothur creates OTUs using a matrix that describes pairwise distances between representative aligned sequences and subsequently estimates within-sample diversity (alpha diversity);B) The Ribosomal Database (RDP) naïve Bayesian classifier assigns each 16S sequence to a reference taxonomy with associated empirical probabilities based on oligonucleotide frequencies;C) Qiime – a python-based workflow package, allowing for sequence processing and phylogenetic analysis using different methods including phylogenetic distance (UniFrac) for within-(alpha diversity) and between-(beta diversity) sample analysis;D) Metastats and custom R scripts used to generate additional statistical and graphical evaluations.Though some of the different protocols used in CloVR-16S overlap in purpose (e.g. OTU clustering), the end-user benefits from their overall complementary nature as they focus on different aspects of the phylogenetic analysis. CloVR-16S accepts as input raw multiplex 454-pyrosequencer output, i.e. pooled pyrotagged sequences from multiple samples, or alternatively, pre-processed sequences from multiple samples in separate files. This protocol is available in CloVR beta versions 0.5 and 0.6.

Dual host-defence functions of SPLUNC2/PSP and synthetic peptides derived from the protein
Authors: Gorr Sven-Ulrik , Abdolhosseini Mahsa , Shelar Anuradha , Sotsky Julie 
Published: July 2011

PSP (parotid secretory protein)/SPLUNC2 (short palate, lung and nasal epithelium clone 2) is expressed in human salivary glands and saliva. The protein exists as an N-glycosylated and non-glycosylated form and both appear to induce agglutination of bacteria, a major antibacterial function for salivary proteins. Both forms of PSP/SPLUNC2 bind LPS (lipopolysaccharide), suggesting that the protein may also play an anti-inflammatory role. Based on the predicted structure of PSP/SPLUNC2 and the location of known antibacterial and anti-inflammatory peptides in BPI (bactericidal/permeability-increasing protein) and LBP (LPS-binding protein), we designed GL13NH2 and GL13K, synthetic peptides that capture these proposed functions of PSP/SPLUNC2. GL13NH3 agglutinates bacteria, leading to increased clearance by macrophages and reduced spread of infection in a plant model. GL13K kills bacteria with a minimal inhibitory concentration of 5–10 μg/ml, kills bacteria in biofilm and retains activity in 150 mM NaCl and 50% saliva. Both peptides block endotoxin action, but only GL13K appears to bind endotoxin. The peptides do not cause haemolysis, haemagglutination in serum, inhibit mammalian cell proliferation or induce an inflammatory response in macrophages. These results suggest that the GL13NH2 and the modified peptide GL13K capture the biological activity of PSP/SPLUNC2 and can serve as lead compounds for the development of novel antimicrobial and anti-inflammatory peptides.
Modern Food Retailers and Traditional Markets in Developing Countries: Comparing Quality, Prices, and Competition Strategies in Thailand
Authors: Schipmann Christin , Qaim Matin 
Published: July 2011

AbstractSupermarkets and hypermarkets are expanding rapidly in many developing countries. While consequences for farmers and consumers were analyzed recently, little is known about the implications for traditional retail formats such as wet markets. Using data from a market survey in Thailand and hedonic regressions, we analyze quality and prices for fresh vegetables from different retail outlets. Compared to wet markets, modern retailers sell higher quality at higher prices, indicating that they are primarily targeting better‐off consumers, and not directly competing for the same market segments. Yet there are signs that modern and traditional markets will gradually converge. Policy implications are discussed.
Investigation of process parameters in superplastic free bulge forming
Authors: Sedighi M. , Moattari M. 
Published: July 2011

PurposeAerospace industry was pioneered in the use of superplastic forming (SPF) process. Weight saving is the most important need in this industry. For this reason, there is special attention paid to this method. Blow forming is a common method for SPF process. Process parameters such as temperature and pressure have significant effects on part accuracy, quality and desired characteristics. The purpose of this paper is to present a numerical and experimental investigation of process parameters in superplastic free bulge forming.Design/methodology/approachIn this paper, superplastic free bulge forming of Al‐5083 has been studied. First, free bulge tests have been done at two different pressures. Bulge height variations were recorded for different pressure and temperature. The forming time was determined according to the forming pressure and temperature. Then, simulation of free bulge process has been carried out using creep behavior model at high temperature. Bulge height and thickness distribution are obtained at two different pressure settings. These results have been compared with experimental results presenting a good agreement. Also the effects of temperatures and pressure on the required process time are compared for a certain bulge height. Finally, thickness distribution profile for different temperatures, pressures and initial thicknesses have been studied.FindingsA numerical and experimental investigation has been presented that can be used to study the process parameters. These findings show the effects of temperatures, pressure and initial thicknesses on sheet forming.Originality/valueThe results of this work show that higher temperature and forming pressure will reduce the required process time for a certain bulge height. Reduction of these parameters can improve thickness distribution. Also, by considering the effects of both pressure and temperature, it is shown that using lower forming pressure at higher temperature is more suitable for forming. The findings of this work can provide more understanding of the process for aircraft part designers and manufacturing process planners.

Published: July 2011

PurposeThe paper reports an investigation into the use of aqueous extracts of rice bran as a green inhibitor for corrosion of carbon steel in hydrochloric acid (HCl) solution.Design/methodology/approachExtracts from the rice bran were used as the main component of an environmentally friendly corrosion inhibitor for use in HCl pickling processes. Inhibition behavior on carbon steel in HCl was investigated by means of mass‐loss tests, polarization curves, electrochemical impedance spectroscopy and atomic force microscopy.FindingsThe results show that the extract exhibited good inhibition performance in 1 M HCl. The inhibition efficiency increased with increase in the concentration of the inhibitor and was only moderately affected by temperature variations in the range 303‐363 K. The inhibitive action was due to adsorption on the A3 steel and the adsorption process was consistent with the Langmuir isotherm. The free energy of adsorption (ΔGads.) was −4.192 kJ/mol. The negative value of ΔGads. indicated spontaneous adsorption of the inhibitor occurred on the surface of A3 steel.Practical implicationsRice bran extract is an effective inhibitor and can be used to protect carbon steel from corrosion in HCl solution.Originality/valueThe rice bran extracts are an effective green inhibitor and can be widely used in the pickling of metals.
The gender gap in food choice motives as determinants of consumers' attitudes toward GM foods in Taiwan
Authors: Chen Mei‐Fang 
Published: July 2011

PurposeIn addition to having an understanding of consumers' food choice motives which influence their attitudes toward GM foods in Taiwan, the aim of this study is to ascertain whether gender differences play a role in consumers' food choice motives and their attitudes toward GM foods.Design/methodology/approachA total of 12 distinct food choice motives, adapted from the Food Choice Questionnaire (FCQ) is posted on a questionnaire collection web site to collect research data. A total of 522 useful responses were elicited as the data input for analysis.FindingsThe results indicate that mood, sensory appeal, price, and familiarity were found to have positive impacts on consumers' attitudes toward GM foods but natural content is observed to have a negative impact on consumers' attitudes toward GM foods. Moreover, female consumers have a more negative attitude toward GM foods than male consumers when they consider whether GM foods are healthy or not.Practical implicationsThe marketers of this GM foods sector in Taiwan should emphasize the price advantage and the appealing sensory aspects of GM foods. By doing so, consumers could familiarize themselves with such foods being promoted. However, how to prevent them from treating GM foods as unnatural and unhealthy is an important task for GM foods marketers.Originality/valueThis is the first study to investigate the gender gap in food choice motives as a determinant of consumers' attitudes toward GM foods in Taiwan. Based on the empirical findings, some suggestions are provided here to benefit the marketers of this GM foods sector in Taiwan.
