Smooth photogeneration of α,n-didehydrotoluenes
(DHTs)
Authors: Protti Stefano , Ravelli Davide , Fagnoni Maurizio , Albini Angelo
Published: April 2013

Irradiation of the three isomeric (chlorobenzyl)trimethylsilanes in
methanol–water generates the corresponding didehydrotoluenes (DHTs). The process
involves expulsion of a chloride ion to give the triplet phenyl cation and
ensuing elimination of the trimethylsilyl cation. This straightforward
generation of DHT intermediates overcomes a shortcoming of previous methodology
(cycloaromatization of enyne-allenes), which is limited to the
meta-isomer, and opens the path for understanding the
chemistry (and possibly the biological action) of these unusual
intermediates.
Electric-field effects on photoinduced dynamics and
function
Authors: Ohta Nobuhiro
Published: April 2013

Photoinduced electron-transfer processes are enhanced or quenched by application
of electric fields, depending on the donor–acceptor pairs.
Electric-field-induced quenching of photoluminescence, which results from the
field-induced dissociation of the exciton state that depends on the
photoexcitation wavelength, is observed in π-conjugated polymers. These
electric-field effects on photoinduced dynamics have been confirmed by the
measurements both of electroabsorption and electrophotoluminescence spectra and
of time-resolved electrophotoluminescence decays. Time-resolved measurements of
photocurrent, with which novel material function in electrical conductivity of
organic materials induced by photo-irradiation and application of electric
fields is confirmed, are also reviewed.
Bonuses versus Commissions: A Field Study
Authors: Kishore Sunil , Rao Raghunath Singh , Narasimhan Om , John George
Published: April 2013

Quota-based bonuses and commissions are the two most common incentive compensation plans. The authors uncover differential effects of these plans from a natural field-based experiment featuring 14,000 monthly observations over three years from 458 sales territories of a pharmaceutical firm that switched from a bonus plan to an equivalent commission plan. The intervention led to significant sales productivity improvement; this effect was heterogeneous across ability deciles, with much larger increases occurring at lower ability deciles. The authors find significant differences across these plans on (1) effort against nonincentivized tasks and (2) output fluctuations induced through “timing games.” At this firm, the bonus plan was strictly inferior to the implemented commission plan with respect to short-term revenues and timing games. In contrast, the commission plan induced greater neglect of nonincentivized tasks (tasks not directly affecting observable output). To organize their findings, the authors build a simple theoretical model in the personnel economics tradition. The novel result that multitasking concerns are reduced under bonus plans when the quota has been met provides a nuanced rationale for the widespread existence of lump-sum bonus plans.
Predictors of Permanent Housing for Sheltered Homeless Families
Authors: Rocha Cynthia , Johnson Alice K. , McChesney Kay Young , Butterfield William H.
Published: April 2013

The authors analyze 10 years of data on homelessness to determine the characteristics of homeless families most likely to find permanent housing after leaving a shelter environment. They studied 1,156 families from 1983 to 1992 to determine where these families go after leaving the shelter and whether the pattern changed over time. Logistic regression analysis found that the larger the family size and being African American were factors that predicted a decreased likelihood of finding permanent housing. Families with one child were 1.5 times more likely to find permanent housing than were families with three children, and whites were 1.9 times more likely to find permanent housing than were African Americans. Furthermore, homeless shelter residents were five times more likely to find permanent housing in 1983 than in 1992, regardless of demographic predictors. Practice and policy implications are discussed.
Improved hanger design for robustness of through-arch bridges
Authors: Jiang Rui-Juan , Tat Kwong Au Francis , Wu Qi-Ming
Published: April 2013

Hangers in through-arch bridges are important components since they suspend the entire bridge deck from the arch ribs. Local damage at a hanger may lead to subsequent damage of various components in the vicinity or even progressive collapse of the bridge. After reviewing the conventional design of double-hangers in through-arch bridges, this paper puts forward a new design approach. The suitability and robustness of this new approach are then verified by numerical simulation of a real bridge. The impact effects induced by local fracture of a hanger on the other structural members are then simulated by dynamic time–history analyses. The new approach of hanger design is shown to improve the structural robustness. In particular, when one or more hangers are damaged thereby causing local failure, the through-arch bridge will not be endangered and will still maintain reasonable overall load-carrying capacity so that the necessary emergency measures can be taken.
Joseph Locke: pioneer civil engineering project manager
Authors: Barnes Martin
Published: April 2013

Joseph Locke (1805–1860) was one of the four great railway civil engineers of the first phase of railway building in the UK and the wider world. Less well known than Brunel and the two Stephensons, he was a good manager of the projects of which he had charge and certainly the best manager of the four. The technology of civil engineering has changed hugely since Locke's time but the skills of the civil engineering manager have not. The lessons of Locke's career are therefore not only interesting but potentially instructive to modern civil engineers.
Determinants of resilience in community-led waste management
Authors: Zurbrügg Christian , Rothenberger Silke
Published: April 2013

Self-help by individuals and local community groups in solid waste management is widespread in cities of the developing world as a coping strategy to overcome the lack of public services. This study identifies and analyses the driving forces, factors of sustainability, as well as internal and external factors that influence failure or success of solid waste community-based initiatives in India. The ability to reflect on the situation, to judge existing risks and to trust in the capability to master the risks of everyday life in interaction with other persons and organisations forms the framework of analysis, as a core of ‘social and individual resilience’. The concept of resilience is used, together with the sustainable livelihood framework, to analyse eight south Indian community-based solid waste schemes. The results clearly underline the importance of the human and social capital that an individual ‘instigator’ brings to an initiative and highlights the importance of a ‘champion’ in every successful initiative.
Landscape‐scale forest disturbance regimes in southern Peruvian Amazonia
Authors: Boyd Doreen S. , Hill Ross A. , Hopkinson Chris , Baker Timothy R.
Published: April 2013

Landscape‐scale gap‐size frequency distributions in tropical forests are a poorly studied but key ecological variable. Currently, a scale gap currently exists between local‐scale field‐based studies and those employing regional‐scale medium‐resolution satellite data. Data at landscape scales but of fine resolution would, however, facilitate investigation into a range of ecological questions relating to gap dynamics. These include whether canopy disturbances captured in permanent sample plots (PSPs) are representative of those in their surrounding landscape, and whether disturbance regimes vary with forest type. Here, therefore, we employ airborne LiDAR data captured over 142.5 km2 of mature, swamp, and regenerating forests in southeast Peru to assess the landscape‐scale disturbance at a sampling resolution of up to 2 m. We find that this landscape is characterized by large numbers of small gaps; large disturbance events are insignificant and infrequent. Of the total number of gaps that are 2 m2 or larger in area, just 0.45% were larger than 100 m2, with a power‐law exponent (α) value of the gap‐size frequency distribution of 2.22. However, differences in disturbance regimes are seen among different forest types, with a significant difference in the α value of the gap‐size frequency distribution observed for the swamp/regenerating forests compared with the mature forests at higher elevations. Although a relatively small area of the total forest of this region was investigated here, this study presents an unprecedented assessment of this landscape with respect to its gap dynamics. This is particularly pertinent given the range of forest types present in the landscape and the differences observed. The coupling of detailed insights into forest properties and growth provided by PSPs with the broader statistics of disturbance events using remote sensing is recommended as a strong basis for scaling‐up estimates of landscape and regional‐scale carbon balance.
Bed Load Erosion Patterns and Their Effect on the Structural Strength of Rigid Pipes Made of Homogeneous Materials
Authors: Rubin Hillel , Tokarev Dmitry , Rubin Eran , Schuttrumpf Holger
Published: April 2013

This manuscript concerns the decrease of the structural strength of rigid pipes made of homogeneous materials
due to bed load erosion, caused by different concentrations of hard solid particles transported by the sanitary sewage, or
surface runoff. Such a phenomenon has been observed in combined sanitary systems (CSS), as well as in force mains delivering
domestic sewage due to the penetration of hard solid particles into the sanitary sewerage system. Field observations
have indicated that the low concentrations of solid particles transported with the sewage lead to the formation of a
groove at the pipe invert. Experiments carried out in this study have shown that the width of the groove mainly depends
on the concentration of the solid particles. Numerical simulations have indicated that bed load erosion resulting from very
low concentrations of solid small particles may be more detrimental to the structural strength of the pipe than higher concentration
of such particles.
Observations of the 9 June 2002 Dryline During IHOP
Authors: Cai Huaqing , Lee Wen-Chau
Published: April 2013

Detailed studies of drylines that do not initiate storms are rare but scientifically important. Studying these null
cases will improve the understanding of critical factors separating whether convection would be initiated along a dryline.
This observational study presents a null case dryline near the Oklahoma/New Mexico border during the International H2O
Project (IHOP_2002) on 9 June 2002. High-resolution observations obtained from an airborne Doppler radar (ELDORA),
two water-vapor Differential Absorption Lidar (LEANDRE II and LASE), Learjet dropsondes, as well as aircraft in situ
measurements were used to describe the dryline environment and mesoscale structures in both along- and cross-line
directions. The 9 June dryline was characterized by a rather broad radar reflectivity thinline with a large moisture gradient.
Its updrafts were found generally associated with the local maximum of radar reflectivity; however, they were not colocated.
The simultaneous observations from ELDORA and LEANDRE II confirmed that the dryline updrafts tend to be
located near its moisture gradient, consistent with previous findings using aircraft in situ measurements.

The dryline moisture boundary was found to be greatly modified by mesocyclone circulations, which caused the alongline
moisture gradient at certain segments of the dryline to become greater than the cross-line moisture gradient. Twodimensional
water vapor fields derived from LEANDRE II across the dryline clearly showed the moisture gradient
associated with the dryline and moisture variations on the order of ~ 1 g kg-1 on both sides of the dryline. No storms
initiated within the IHOP_2002 domain associated with this dryline owing to unfavorable atmospheric instability
conditions and only weak upward forcing near the dryline.
Results of applying gonadorelin Fertagyl on the progesterone concentrations in the blood serum and cow conception
Authors: Mlaco N. , Katica A. , Cengic B. , Sakic V.
Published: April 2013

Considering there are different and inconsistent results of the wider use of
gonadotropin-releasing hormone or its analogs in cattle breeding and due to
scarce research studies in the field of individual breeding, we decided to
explore the influence of gonadorelin Fertagyl on the results of the blood
serum progesterone levels and conception of cows in veterinary field
practice. Examination of the progesterone levels involved 14 (fourteen) cows
treated with gonadorelin (GnRH), Fertagyl, manufactured by Intervet,
according to the manufacturer?s instructions dose of 2,5ml (250 micrograms),
within five minutes after insemination. There are individual differences in
progesteron concentrations according to days of sampling in treated cows,
respectively individuality is manifested in all cows between days of blood
sampling, except for period of luteolysis (18th day) in non-gravid cows. Our
research results indicate that there is a tendency for progesterone
concentration to increase in gravid cows treated with Fertagyl at the time of
insemination. Progesteron concentrations in blood serum in gravid cows were
higher for 0.21 ng/ml in first three days after insemination and at 6th day
those concentrations were higher for 0.40 ng/ml compared to non-gravid cows.

Authors: Kucevic D. , Plavsic M. , Trivunovic S. , Radinovic M. , Bogdanovic V.
Published: April 2013

The aim of this paper was to determine the microclimatic conditions (ambient
temperature and relative humidity) in dairy farm, as well as to evaluate the
effect and significance of temperature - humidity index (THI) values on the
daily milk yield. The observation of microclimatic parameters was conducted
in the period from 9.03.2012 to 6.05.2012. The study included 136 Holstein
Friesian cows. The estimation of the effect of THI on daily production of
dairy cows was defined by applying fixed-effect statistical model. Average
ambient temperature during measuring months amounted to 15.6?C (ranging from
7.2? C to 24.6?C), while the average value of relative humidity was 56.33%
(ranging from 40.30% to 81.80%). During the study, the mean value of THI was
58.93 (ranging from 47.08 to 70.13) and didn?t exceed the critical comfort
level of 72. All tested fixed-factors were statistically affected the daily
milk yield (p <0.01). For each unit of increase in the value of the THI, the
amount of milk decreased by 0.05344 kg. This confirmed the importance of
regular recording of THI values and microclimatic conditions as a unique
indicator of thermal stress in dairy farm.
Principal component analysis of the conformation traits of Yankasa sheep
Authors: Yakubu A.
Published: April 2013

This study was preformed to evaluate the biometric traits of 227 Yankasa
sheep in northern Nigeria under a multivariate approach. The body
measurements taken were: withers height, rump height, body length, heart
girth, tail length, face length, shoulder width, head width, rump width, ear
length, foreleg length, hind leg length and rump length. The animals were
divided into two age groups: <15.5 and 15.5 - 28.3 months old, respectively.
General linear model was used to study age group effect while principal
component factor analysis was performed to define body shape upon the
correlation matrix of the thirteen body measurements. Age group significantly
(P<0.05) affected the morphological characters except ear length. Pearson?s
coefficients of correlation were positive and significant in both age groups.
In <15.5 months old sheep, four principal components (factors) were extracted
(ratio of variance = 89.27). The first factor accounted for 73.03% of the
total variance and was interpreted as a measure of general size. The second
factor which explained 7.61% of the generalized variance tended to describe
flesh dimensions (shoulder width and rump width), while the third factor had
its loadings for tail length and ear length. The fourth factor was influenced
by head width. In 15.5-28.3 months old sheep, three factors (ratio of
variance=75.21) were identified. These seven extracted factors could be
considered in breeding programmes to improve body conformation of sheep since
variation in meat traits was not associated with body height.

Measuring of back fat thickness in the loin part (FT1), between 3rd and 4th
lumbar vertebrae, 7cm laterally to the back line; back fat thickness (FT2)
and depth of the musculus longissimus dorsi (MLD) between the 3rd and 4th rib
from the rear, 7cm laterally to the back line. Assessment of meat yield was
done using the ultrasonograph apparatus Piglog 105. In regard to meat yield
indicators, medium heritability values were established for FT1 h2=0.461, and
high values for FT2 h2=0.639, and for meat yield h2=0.633. Low heritability
was established for depth of MLD (h2=0.105), life daily gain (h2=0.110) and
age at the end of test (h2=0.103). Established phenotypic correlations
between fat thickness FT1 and FT2 were strong (rp=0.638); between fat
thickness and meat yield very strong (rp=-0.880 to -0.895), and between fat
thickness and MLD very weak and negative (rg=-0.103 to -0.216). Genetic
correlations were stronger than phenotypic, so between fat thickness FT1 and
FT2 the correlation was complete/full (rg=0.930), also between fat thickness
and meat yield (rg=-0.979 to -0.982), whereas the correlation between fat
thickness and MLD was strong and negative (rg=-0.627 to -0.653). Heritability
values for fat thickness and meat yield show that these traits have high
level of heritability and are transfered to the progeny, whereas the level
and strength of their dependance show that by decreasing the fat thickness
positive influences is exhibited on meat yield, and that by increasing of
depth of MLD also the meat yield is increased.
Influence of some bio-products on the biological and productive characteristics of bird’s foot trefoil grown for forage
Authors: Churkova B.
Published: April 2013

During the 2010-2012 period the influence of some bioproducts being mainly a
combination of macro and micronutrients at different concentrations on the
productivity, botanical and morphological composition of bird?s foot trefoil
swards was studied. The experiment was carried out on the experimental field
of the IMSA - Troyan by the completely randomized method with 4 replications
and harvest plot size of 5 m2. Four bio-products phosphorus humate in dose of
3000 l/ha, boron humate (1600 l/ha) and molybdenum humate (1600 l/ha) and
their combination phosphorus humate (2500 l/ha) + boron humate (1000 l/ha) +
molybdenum humate (1000 l/ha) were studied. They were applied at the 2-4
leaf. The results showed that solely phosphorus humate had a positive
influence, which increased the dry matter yield only by 8.7% and the results
were not statistically significant.. It was found that the data had a
unidirectional character with regard to the leafiness degree during the years
as a result of the applied bio-fertilizers. Their application had a positive
effect on the leafiness. The phosphorus humate showed a tendency to increase
the relative portion of stems in the sward from the first to the third year.
The kind of the applied bio-fertilizers was not of substantial importance to
the degree of stem growth and botanical composition of the sward.
The effect of the first fertile floor on qualitative: Quantitative properties of soybean seed
Authors: Andjelovic S. , Maksimovic S. , Savic D. , Tomic Z. , Delic D.
Published: April 2013

The aim of this study was to determine the effect of height of the first
fertile floor on the qualitative and quantitative characteristics of soybean
seeds. For qualitative traits the focus was on the energy of germination and
seed germination of the studied genotypes investigated per soybean plant and
the first fertile floor of the plant. Results of research indicated that
there were significant differences between genotypes observed by
morphological characteristics (plant height, height of first fertile floor,
number of fertile floors, number of pods and seeds, seed weight, etc.) as
well as qualitative properties (energy of germination and seed germination).
Cultivar Gorstak, with genetically incorporated height of the first fertile
floor (12.38 cm), was superior to other two genotypes. A similar trend was
found in other morphological analyses. Based on energy of germination and
seed germination of all fertile floors per plant, there were no significant
differences between soybean genotypes. However, of paramount importance are
the established values of these parameters relevant to the first fertile
floor. Cultivar Gorstak had significantly higher energy of germination
(90.46%) and total germination (91.00%) compared to the other two genotypes.
A contribution to automated-oriented reasoning about permutability of sequent calculi rules
Authors: Lutovac Tatjana , Harland James
Published: April 2013

Many important results in proof theory for sequent calculus (cut-elimination,
completeness and other properties of search strategies, etc) are proved using
permutations of sequent rules. The focus of this paper is on the development
of systematic and automated-oriented techniques for the analysis of
permutability in some sequent calculi. A representation of sequent calculi
rules is discussed, which involves greater precision than previous
approaches, and allows for correspondingly more precise and more general
treatment of permutations. We define necessary and sufficient conditions for
the permutation of sequence rules. These conditions are specified as
constraints between the multisets that constitute different parts of the
sequent rules. The authors extend their previous work in this direction to
include some special cases of permutations.

Published: April 2013

A comprehensive analysis of physicochemical parameters in geothermal waters
from the sites in Sijarinska spa (drill hole B-4) and Vranjska spa (drill
hole VG-2) in order to investigate their tendency to form deposits in the
pipe installation is presented. Drill holes B-4/VG-2 posses utilization
capacity of 30/27 L s-1 with water temperatures 75/90 oC. VG-2 water does not
show any tendency to (or shows very small) sedimentation compared to the B4
water. The behaviour of the geothermal water from the B-4 hole was examined
in real condition in Sijarinska spa, by letting it flow through the pipe
installation. The results of geochemical analysis of water B-4 show that
aragonite is the predominant mineral in the sediment (98 %) with lesser
amount of calcite, vaterite and anhydrite.

Published: April 2013

The coupling of diazotized 2-aminothiazole and 2-aminobenzo-thiazole with
cyclohexane-1,3-dione yielded a new type of tridentate ligand systems (HL).
Analytical, IR, 1H NMR, 13C NMR and mass spectral data indicate the existence
of the compounds in the intramolecularly hydrogen bonded azo-enol tautomeric
form. Monobasic tridentate coordination of the compounds in their [CuL(OAc)]
and [ML2] complexes [M = Ni(II) and Zn(II)] has been established on the basis
of analytical and spectral data. The Zn(II) chelates are diamagnetic while
Cu(II) and Ni(II) complexes showed normal paramagnetic moment.

Population dynamics of pre-imaginal stages of olive fruit fly Bactrocera oleae Gmel. (Diptera, Tephritidae) in the region of Bar (Montenegro)
Authors: Perovic Tatjana , Hrncic Snjezana
Published: April 2013

Olive fruit fly is the most harmful pest of olive fruits and important for
oil production. Damage involves yield reduction as a consequence of premature
fruit drop, but also a reduced quality of olive oil and olive products. There
is little available data regarding the biology of Bactrocera oleae in
Montenegro. Knowledge of the pest life cycle and development would improve
optimization of insecticide application timing and protection of fruits, and
reduce adverse effects on the environment. Investigation was conducted on the
Zutica variety in an olive grove located in Bar during a three-year period.
Population dynamics of the pre-imaginal stages and level of fruit infestation
were monitored from mid-July until the end of October. The results of this
three-year investigation showed that the beginning of infestation was always
at the end of July. It was also found that, depending on environmental
conditions, the level of infestation was low until the end of August. In
September and October it multiplied, and reached maximum by the end of
October. Regarding infestation structure, eggs and first instar larvae were
the dominant developmental stages of the pest until the middle of September.
From mid-September until mid-October all developmental stages (eggs, larvae,
pupae) were equally present in infested fruits. Pupae, cocoons and abandoned
galleries prevailed until the harvest.

Foraging activity of four bee species, Apis mellifera L., Osmia spp.,
Ceratina tarsata Morawitz and Xylocopa pubescens Spinola on sesame flowers
was studied during two successive seasons of 2011 and 2012. Experimental
observations were made during four periods of the day: 9:00-11:00 am, 11:00
am-1:00 pm, 1:00-3:00 pm and 3:00-5:00 pm, starting from initial flowering
until the final session. Observation time was five minutes during each period
and four bee species were observed visiting each square meter area. Five
spots of 1 m2 area were selected randomly, and the number of different
species of bees visiting was counted for five minutes by using electronic
stopwatch, voice recorder and digital video camera. The results of the study
indicated that the four bee species were most abundant on sesame flowers
between 11:00 am and 1:00 pm, and between 1:00 and 3:00 pm. Among the bees,
Apis mellifera was the predominant species, followed by Ceratina tarsata, in
the season of 2011, while a reverse order of the two was recorded in 2012.
The average time spent per flower was highly significantly different among
these four species.
Analysis of Academic Journals in Education: A Comparison of Publication Patterns in England and Germany
Authors: Ertl Hubert , Zierer Klaus , Phillips David , Tippelt Rudolf
Published: April 2013

This article outlines some of the findings of a project funded by the German Research Association which conducted an analysis of six leading journals of education in Germany and England. All articles published in these journals between 2001 and 2009 were analysed according to thematic foci, methodological approaches and characteristics of authors. The findings of this analysis demonstrate that there are clear differences and similarities in publication patters between different journals and countries and that some of these patterns have changed substantially over time. The comparative perspective used for the analysis results in conclusions regarding nation-specific trajectories of the discourse and research in the area of education.
Nurturing Young Children's Moral Development through Literature in Japan and the USA
Authors: Izumi-Taylor Satomi , Scott Jerrie C.
Published: April 2013

The purpose of this study was to examine the views of American and Japanese early childhood teachers regarding the nurturing of young children's moral development using literature. The data consisted of responses to a questionnaire and written explanations of 36 American and 36 Japanese teachers. By comparing responses of the two groups, it was possible to identify both similarities and differences in American and Japanese early childhood educators' philosophical and pedagogical views on nurturing young children's moral development. Accounting largely for similarities in responses were generic items, such as beliefs in the importance of nurturing children's hearts/spirits and in the value of using literature to nurture them. Differences were reflected in particular aspects of philosophical beliefs and pedagogical practices. The study revealed that the sources of different viewpoints may be attributed to a combination of culturally specific patterns and curriculum guidelines to which teachers are exposed.
Educational Disparities and Conflict: Evidence from Lebanon
Authors: Tfaily Rania , Diab Hassan , Kulczycki Andrzej
Published: April 2013

This article examines the impact of Lebanon's civil war (1975–1991) on disparities in education among the country's main religious sects and across various regions. District of registration is adopted as a proxy for religious affiliation through a novel, detailed classification to assess sectarian differentials by region and regional differentials within each major religious group. Findings show that the civil war helped close the gender gap in education across various sects/regions, presumably because many young men joined militias. However, the education of Muslims still lags behind that of Christians. Intra-sectarian disparities remain very pronounced, especially among Sunni Muslims. The article shows that Lebanon's regional and sectarian inequalities that pre-dated the civil war have been largely maintained. The civil war and its aftermath, however, have led to some shift in the balance of power and to some changes in the ranking of particular sects and regions. Drawing upon the work of Weber and Lenski, the authors argue that sectarian/regional inequalities in education in Lebanon are the product of disparities in economic power and differential access to the state resources among the various regions and sects. They conclude by discussing the future of educational inequalities in Lebanon.

Published: April 2013

Our hypothesis was that a method of caries activity evaluation based on the clinical features of the lesions would be less time consuming but more influenced by the examiner's experience than the scoring system used in association with the International Caries Detection and Assessment System (ICDAS). Thus, the aim of this study was to evaluate the performance of three groups of examiners with different levels of experience using two different methods to assess the activity status of caries lesions by visual inspection. A cross-sectional study in a dental office setting was performed selecting 18 children, aged three to eight years, who had sought dental treatment at a dental school. Examinations to detect caries lesions were performed using visual inspection by six examiners with different levels of experience: two undergraduate dental students, two specialists in pediatric dentistry, and two graduate students. The examiners used ICDAS and two different methods to assess caries activity: using an additional score system or considering the examination of clinical features. Two benchmark examiners examined the children in a joint session, and their consensus was considered to be the reference standard. The sensitivity, specificity, and reproducibility were calculated for different thresholds: all, cavitated, and active caries lesions. Multilevel analyses were performed to compare the different methods and examiners. No differences were observed among the examiners, either in detecting all lesions and cavitated lesions or regarding the activity assessment. The methods of assessing activity status performed similarly, but the time spent on examinations was shorter for the method evaluating clinical features. In conclusion, the experience of examiners does not significantly influence the performance of visual inspection, and both methods of assessing activity status result in similar diagnostic accuracy.
Synthetic adjacent pulse repetition interval length method to solve integer ambiguity problem: theoretical analysis
Authors: Wei D. , Takamasu K. , Matsumoto H.
Published: April 2013

This paper describes a novel approach for realizing femtosecond optical frequency comb (FOFC)-based length measurement. This approach is based on the analogy between the phase unwrapping problem and the integer ambiguity problem. Because the conventional synthetic wavelength method can solve the former, we investigated the possibility of using a synthetic adjacent pulse repetition interval length method to solve the latter. The results of theoretical analyses and numerical investigations show the feasibility of the proposed method. Our results should contribute toward the further development of FOFC-based length measurement methods.
Optical and THz Galois diffusers
Authors: Jaax M. , Wolff S. , Laegel B. , Fouckhardt H.
Published: April 2013

Binary surface reliefs with sub-wavelength features making up a pseudorandom pattern based on mathematical Galois fields GF(pm) [1, 2] can scatter incoming waves into a large number of diffraction maxima within a huge solid angle. A one-dimensional (1D) Galois number sequence can be folded into a two-dimensional (2D) array by the sino-representation [2]. This concept was been verified for acoustic waves a long time ago [3, 4] and is investigated here for visible light and THz waves. Our Galois diffusers are designed as reflection reliefs and realised by electron beam lithography for the optical regime and UV photolithography for the THz regime. Our results show that optical and THz Galois surfaces are excellent diffusers for electromagnetic waves; they distribute the reflected intensity evenly over a large number of maxima nearly within the entire half solid angle in the backward direction.

Basal melting beneath a fast-flowing temperate tidewater glacier
Authors: Alexander D.J. , Davies T.R.H. , Shulmeister J.
Published: April 2013

The role of melting at the base of temperate tidewater glaciers is rarely discussed, and its potential importance for total glacier mass balance and subglacial dynamics is often overlooked. We use Columbia Glacier, Alaska, USA, as an example of a temperate tidewater glacier to estimate the spatial distribution of basal melt due to friction both before and during the glacier’s well-documented retreat since the early 1980s. Published data on glacier surface and bed profiles, ice-flow velocities and surface melt were collated and used as input data for a two-dimensional basal melt model. We estimate that before the retreat of Columbia Glacier (pre-1980s), mean basal melt amounted to 61 mm a–1, increasing to 129 mma–1 during retreat (post-1980s). According to our calculations, basal melt accounts for 3% and 5% of total glacier melt for the pre-retreat and syn-retreat (i.e. during retreat) glacier profiles, respectively. These calculations of basal melt are an order of magnitude greater than those typically reported in polar glacier settings. Basal melting in temperate tidewater settings may be a non-negligible process affecting glacier mass balance and subglacial dynamics.
