Comparison of unique hue stimuli determined by two different methods using Munsell color chips
Authors: Shamey Renzo , Sedito Michael G. , Kuehni Rolf G.
Published: January 2010

Unique hue stimuli were determined by male and female observers using two different visual experimental procedures involving Munsell color chips of varying hue but identical chroma and value. The hypothesis was that unique hues can be more reliably established by explicit selection from a series of ordered stimuli than implicitly by hue scaling a series of stimuli in terms of neighboring UHs and this was statistically confirmed. The implicit selections based on long term memory of UHs appears to have been more challenging to observers since variability was increased by nearly 50% compared to when UHs were explicitly selected. The ranges of unique hues selected in the two methods were, however, comparable and no statistically significant difference was found between the results of females and males. The intra‐observer variability in picking a stimulus to represent a unique hue, for all observers and averaged for all hues, was approximately 12% of the mean spread of unique hues, confirming that the large inter‐observer variability is driven by differences in color vision and perhaps cognitive processes. © 2010 Wiley Periodicals, Inc.

Michromatic scope for enhancement of color difference
Authors: Kaarna Arto , Nishino Ken , Miyazawa Kanae , Nakauchi Shigeki
Published: January 2010

A michromatic (microscope plus chromatic) scope is a device that enhances the color discrimination between two spectral color datasets. Three spectral filters are required, instead of the conventional red, green, and blue filters, for the implementation of a michromatic camera. In this study, we describe two approaches to the design of these filters: in the first case, the design is based on the direct optimization of the filter characteristics (transmittance), whereas in the second case, the design is based on the nonnegative tensor factorization (NTF) of the spectral datasets. A michromatic camera can be implemented using these filters along with compatible postprocessing in‐camera firmware. Here, we performed experiments with two color datasets: one comprising skin and vein colors, and one comprising skin and cosmetics colors. These were further divided into a training set and a test set. The filters were defined using the training set, and the operation of the filters was tested and magnified using the test set. Our experiments demonstrated that the proposed approaches are suitable for color discrimination. For the first color dataset, the enhancement produced using the optimized filters was up to 252% of the original value, and the average color difference ΔEwas increased from 2.82 to 9.93. NTF and preprocessing further enhanced the ΔEup to 21.84. For the second color dataset, NTF and postprocessing enhanced the ΔEfrom 4.33 to 29.19. The proposed discrimination enhancement could be physically implemented in a designated digital charge‐coupled device camera with proper filter installation and compatible postprocessing. © 2010 Wiley Periodicals, Inc.

Colour research with architectural relevance: How can different approaches gain from each other?
Authors: Anter Karin Fridell , Billger Monica
Published: January 2010

Colour research from different scientific traditions start from different basic questions and use different methods and concepts. This makes it difficult to communicate and to judge result relevance in a wider perspective. Here we start from architects' need of colour knowledge and discuss recent studies of colour appearance and colour emotion, with and without explicit connection to architecture. We stress the need for further development and clarification of concepts and conclude that the multitude of studies with different approaches can be seen as cases, jointly adding to a widened and deepened understanding of colour. © 2010 Wiley Periodicals, Inc.

A brief history of disk color mixture
Authors: Kuehni Rolf G.
Published: January 2010

Disk color mixture, known since antiquity, represents a special kind of additive color mixture where the stimuli do not represent direct lights from light sources but light reflected from objects. Its complete elucidation took centuries, requiring means to measure reflectance properties and spectral powers of lights. Explanations of the cause of the mixture, the fact that perceptions are not instantaneous but take a certain amount of time were offered in the late 17th and early 18th centuries. The speed of disk rotation required to obtain additive fusion of reflected lights was determined in 1765. For a time in the second half of the 19th century disk mixture was the only means of establishing color matching equations and quantitatively defining color stimuli. The fact that its results neither agree with Newtonian predictions of spectral light mixture nor with the results of pigment mixture produced endless confusion in scientific and artistic circles in the Enlightenment. Today, there is no practical application of disk color mixture left and it has become a curiosity. © 2010 Wiley Periodicals, Inc. Col Res Appl, 2010
Graphene on Au(111): A Highly Conductive Material with Excellent Adsorption Properties for High‐Resolution Bio/Nanodetection and Identification
Authors: Song Bo , Li Di , Qi Wenpeng , Elstner Marcus , Fan Chunhai , Fang Haiping
Published: January 2010

Based on numerical simulations and experimental studies, we show that a composite material which consists of a sheet of graphene on a Au(111) surface exhibits both an excellent conductivity and the ability to stably adsorb biomolecules. If we use this material as a substrate, the signal‐to‐noise ratios can be greatly enhanced. The key to this unique property is that graphene can stably adsorb carbon‐based rings, which are widely present in biomolecules, due to π‐stacking interactions while the substrate retains the excellent conductivity of gold. Remarkably, the signal‐to‐noise ratio is found to be so high that the signal is clearly distinguishable for different nucleobases when an ssDNA is placed on this graphene‐on‐Au(111) material. Our finding opens opportunities for a range of bio/nano‐applications including single‐DNA‐molecule‐based biodevices and biosensors, particularly, high‐accuracy sequencing of DNA strands with repeating segments.

Purpose

The impact of weight on quality of life (IWQOL‐Lite) is a self‐administered instrument that assesses quality of life in obesity. It is composed of 31 items and five domains (physical function, self‐esteem, sexual life, public distress, and work). The aim of the present study was to evaluate reliability (test‐retest), internal structure, construct validity and discriminant validity.

Methods

IWQOL‐Lite scores were obtained from 89 people in a Weight Watchers institution (clinical sample) and 156 community volunteers (community sample). The participants were selected based on the same criteria: gender (female) and age (> 24 years), except for BMI. The community sample also completed the SF‐36, a generic measure of health‐related quality of life.

Results

The Brazilian IWQOL‐Lite demonstrated good test‐retest reliability, internal consistency, discriminative validity and convergent validity.

Conclusions

The IWQOL‐Lite is the first specific instrument validated in Brazil for assessing quality of life in obesity. The results reveal that IWQOL‐Lite is an instrument with good psychometric properties. Nevertheless, in some cases results were dissimilar to those reported in earlier studies using the original American English. Copyright © 2010 John Wiley & Sons, Ltd and Eating Disorders Association.
A comparison of the external morphology of the membranous inner ear in elasmobranchs
Authors: Evangelista Carla , Mills Morena , Siebeck Ulrike E. , Collin Shaun P.
Published: January 2010

Studies on the elasmobranch inner ear have focused predominantly on a small group of sharks, particularly, carcharhinids. As a result, subsequent studies in other species have subdivided species into two main groups: those typical and those atypical of carcharhinid sharks. This study proposes a different set of inner‐ear morphology groupings to those previously suggested. The inner ears from 17 species of elasmobranchs (representing both sharks and rays) are examined in this study and based on morphometric data some groups include both rays and sharks. Four groups are now proposed based predominantly on the shape and dimensions of the membranous otoconial organs, and characteristics of the semicircular canals. Evident morphological differences between the ear types belonging to the new groups include the membranes of the semicircular canals being bound to the otoconial organs in some species, while only being connected via the canal ducts in others, as well as clear variation present in saccular organ size. Previous studies examining variation in the inner ear have attributed differences to either phylogeny or functional significance. Results from this study suggest that neither phylogeny nor feeding strategy solely accounts for the morphological diversity present in the external morphology of the elasmobranch inner ear. J.

The purpose of this study was to compare the effects of estrogen deficiency and bone mass loss on normal knee cartilage in mature rabbits. Bilateral ovariectomy (OVX) was performed in 13 rabbits, 6 of which also received systemic glucocorticoid for 4 weeks. Seven additional healthy rabbits were used as controls. Bone mineral density (BMD) was measured by dual X‐ray absorptiometry in lumbar spine, knee, and subchondral bone of the knee at baseline and 22 weeks after OVX. After sacrifice, the knees were dissected, macroscopy was assessed, and histological cartilage abnormalities were evaluated according to the Mankin score. Correlations of Mankin with BMD at different regions were also performed. When compared to baseline, differences in BMD were only found in spine and knee of the animals receiving glucocorticoids. All the animals subjected to OVX had a significantly higher Mankin score than controls. Mankin was upper in OVX animals receiving glucocorticoids, but differences were not significant. The Mankin score was inversely related with BMD in lumbar spine (r = −0.67; p < 0.01). Although low bone mineral density contributes to the minor osteoarthritic alterations observed in our model, estrogen deficiency itself seems to act directly to induce the main pathogenic effects in healthy cartilage of the rabbit. © 2010 Orthopaedic Research Society.

The influence of sequential debridement in total knee arthroplasty on the flexion axis of the knee using computer‐aided navigation

Published: January 2010

The effects of osteophyte debridement, bony cuts, and soft tissue releases on the functional flexion axis of the knee can be assessed by evaluating 3D kinematics following each step of a total knee arthroplasty. Using a navigated knee system with dedicated software, the functional flexion axis (helical axis) can be determined after each step. Five paired fresh‐frozen cadaveric knees were used with a CT scan performed on each specimen identifying implanted fiducial markers. Kinematics data were recorded during each step of sequential osseous cuts and soft tissue releases for both an unloaded and loaded limb by each of three surgeons. The functional helical (flexion/extension) axis was identified for all specimens. The internal/external rotation angle (θ) of the helical axis differed from the transepicondylar axis by −8.3° to +6.7° for the unloaded condition. θ ranged from −7.2° to +7.4° with distraction. Soft tissue releases had no effect on θ; until a bony cut of the articular surface, which increased θ from −0.3° to +9.7°. Implantation of cruciate retaining prosthetic components subsequently reduced the θ range −7.3° to +4.0°. Thus, soft tissue releases had minimal effect on θ of the helical axis except for resection of the proximal tibia. Implantation of the CR prosthesis reduced è close to that of the intact knee. In a minority of knees, the helical axis did not coincide exactly with the transepicondylar axis. Interspecimen and left/right variability of θ were significant, although interinvestigator variability and an applied distraction force were insignificant. © 2010 Orthopaedic Research Society.

Rotator cuff tears are difficult to manage because of the structural and mechanical inhomogeneity of the supraspinatus tendon. Previously, we showed that with the arm at the side, the supraspinatus and infraspinatus tendons mechanically interact such that conditions that increase supraspinatus tendon strain, such as load or full‐thickness tears, also increase infraspinatus tendon strain. This suggests that the infraspinatus tendon may shield the supraspinatus tendon from further injury while becoming at increased risk of injury itself. In this study, the effect of glenohumeral abduction angle on the interaction between the two tendons was evaluated for supraspinatus tendon partial‐thickness tears and two repair techniques. Principal strains were quantified in both tendons for 0°, 30°, and 60° of glenohumeral abduction. Results showed that interaction between the two tendons is interrupted by an increase in abduction angle for all supraspinatus tendon conditions evaluated. Infraspinatus tendon strain was lower at 30° and 60° than at 0° abduction angle. In conclusion, interaction between the supraspinatus and infraspinatus tendons is interrupted with increase in abduction angle. Additionally, 30° abduction should be further evaluated for management of rotator cuff tears and repairs as it is the angle at which both supraspinatus and infraspinatus tendon strain is decreased. © 2010 Orthopaedic Research Society.

A hydroponic experiment was carried out to study effects of chromium (Cr) stress on the subcellular distribution and chemical form of Ca, Mg, Fe, and Zn in two rice genotypes differing in Cr accumulation. The results showed that Ca, Mg, Fe, and Zn ions were mainly located in cell walls and vacuoles in roots. However, large amounts of metal ions were transferred from the vacuole to the nucleus and to other functional organelles in shoots. Chromium concentrations in the nutrient solution of 50 μM and above significantly decreased Ca concentrations in the chloroplast/trophoplast, the nucleus, and in mitochondria. It further increased Mg concentrations in the nucleus and in mitochondria, as well as Zn and Fe concentrations in the chloroplast/trophoplast. These Cr‐induced changes in ion concentrations were associated with a significant reduction in plant biomass. It is suggested that Cr stress interferes with the functions of mineral nutrients in rice plants, thus causing a serious inhibition of plant growth. The chemical forms of the four nutrients were determined by successive extraction. Except for Ca, which was mainly chelated with insoluble phosphate and oxalic acid, Mg, Zn, and Fe were extractable by 80% ethanol, d‐H2O, and 1μM NaCl. The results indicated that these low–molecular weight compounds, such as organic acids and amino acids, may play an important role in deposition and translocation of Mg, Zn, and Fe in the xylem system of rice plants.
Managing soils for a warming earth in a food‐insecure and energy‐starved world
Authors: Lal Rattan
Published: January 2010

World energy consumption increased from 11.5 EJ in 1860 to 463 EJ in 2005, and is projected to be 691 EJ in 2030 and 850 EJ in 2050. The principal driver of such a drastic surge in energy demand is the increase in world population which was merely 1 billion in 1800, 1.6 billion in 1900, 6.0 billion in 2000, and is projected to be 7.5 billion in 2030 and 9.2 billion in 2050 before stabilizing at ≈10 billion by 2100. Heavy reliance on fossil‐fuel consumption has increased atmospheric CO2 abundance from 280 ppm in 1750 to 383 ppm in 2008 and is increasing at ≈2 ppm (4.2 Pg) per year along with the attendant threat of climate disruption. Similar to the close link between energy use and atmospheric chemistry, there also exists a close link between food insecurity and climate change through degradation of soils and desertification of the ecosystems. Global annual per capita cereal consumption increased from 267 kg in 1950, peaked at 339 kg in 1985, and decreased to 303 kg by 2000. In the quest for identifying alternate sources of energy, world production of bioethanol (mostly from corn grains in USA and sugarcane in Brazil) was 65 billion L, and that of biodiesel was 13 million Mg (t) (55% in EU countries) in 2008. Conversion of lignocellulosic biomass, using crop residues or establishing energy plantations, has severe constraints of the additional requirements for land area, water, and plant nutrients. Removal of crop residues for energy and other uses has severe adverse impacts on soil quality and agronomic productivity. Yet, globally average crop yields must be increased by 60% to 120% between 2000 and 2050 for meeting the needs of increase in population and change in dietary habits. Meeting demands of the growing world population and rising aspirations necessitate serious and objective considerations of change in food habits (to a more vegan diet), improvement in energy‐use efficiency, increase in crop yield per unit area and input, restoration of degraded soils and ecosystems, widespread adoption of recommended soil and crop practices, and identification of non‐C fuel sources.
Anticipating Italian census tourism data before their official release: a first solution and its implementation to Piemonte, Italy
Authors: Fontana Roberto , Pistone Giovanni
Published: January 2010

Tourism is a complex and highly competitive sector. In this scenario, incoming tourism flows represent one of the key indicators for public institutions, willing to adopt an informed decision‐making process for resource allocation. The accurate and timely knowledge of both the inter‐regional and the foreign component at a sufficiently detailed geographical level of such flows allows a better strategical, tactical and operational planning of marketing activities. The paper describes a methodology to complete the database of the official statistical data on tourism flows with an estimate of missing data, which are originated by non‐respondent accommodation structure. The methodology has been applied to the inbound tourism flows into Piemonte, Italy. Copyright © 2010 John Wiley & Sons, Ltd.
