Identification and Confirmation of Quantitative Trait Loci Associated with Soybean Seed Hardness
Authors: Orazaly Moldir , Chen Pengyin , Zeng Ailan , Zhang Bo
Published: February 2015

Food‐grade soybeans [Glycine max (L.) Merr.] have specific seed quality requirements, such as seed texture and hardness. Cooked seed hardness is important for soyfood such as natto and edamame, where cooking is required. Texture analysis is time consuming and labor intensive; however, the identification of seed hardness quantitative trait loci (QTL) and associated markers will facilitate the development of elite cultivars through marker‐assisted selection. The objectives of this study were to identify new QTL associated with seed hardness and confirm previously reported QTL. A total of 120 recombinant inbred lines, derived from KS4303sp (soft seeded) × PI 407818 B (hard seeded), were screened with 486 simple sequence repeat markers and tested for cooked seed hardness. The F2:4 and F2:5 lines were grown with two replications at Fayetteville and Keiser, AR, in 2008 and 2009. Interval mapping revealed a new putative QTL for seed hardness (Ha3) in an approximate 46‐cM region and linked to markers Satt547 and Satt414 on chromosome 16. This QTL contributed 32% to seed hardness in the KS4303sp × PI 407818 B population. Single marker analysis revealed 14 markers on seven chromosomes associated with seed hardness. In all environments, Satt254 on chromosome 1, Satt677 on chromosome 7, Satt414, Satt547, and Sat_224 on chromosome 16, and Satt292 on chromosome 20 were significantly associated with seed hardness. A chromosomal region previously reported for hardness (QTL Ha2) contained a marker (Satt254 on chromosome 1) that was significant across environments. This study identified a new QTL and confirmed a QTL (Ha2) region that will advance breeding efforts for food‐grade soybean.
Estimation of angiotensin-converting enzyme inhibitors protein binding degree using chromatographic hydrophobicity data
Authors: Trbojevic-Stankovic Jasna , Aleksic Mirjana , Odovic Jadranka
Published: February 2015

Introduction. Angiotensin-converting enzyme (ACE) inhibitors represent a
significant group of drugs primarily used in the treatment of hypertension
and congestive heart failure. Objective. Selected ACE inhibitors (enalapril,
quinapril, fosinopril, lisinopril, cilazapril) were studied in order to
establish a fast and easy estimation method of their plasma protein binding
degree based on their lipophilicity data. Methods. Chromatographic
hydrophobicity data (parameter C0) were obtained on cellulose layers under
conditions of normal-phase thin-layer chromatography (NPTLC), using different
binary solvent systems. The ACE inhibitors lipophilicity descriptors (logP)
values were calculated using the software package Virtual Computational
Chemistry Laboratory. The ACE inhibitors plasma protein binding data were
collected from relevant literature. Results. ACE inhibitors protein binding
data varied from negligible (lisinopril) to 99% (fosinopril). The calculated
lipophilicity descriptors, logPKOWWIN values ranged from -0.94 (lisinopril)
to 6.61 (fosinopril). Good correlations were established between plasma
protein binding values and calculated logPKOWWIN values (R2=0.8026) as well
as chromatographic hydrophobicity data, C0 parameters (R2=0.7662). Even
though good correlation coefficients (R2) were obtained in both relations,
unacceptable probability value with p>0.05 was found in relation between
protein binding data and calculated logPKOWWIN values. Subsequently, taking
into consideration the request for probability value lower than 0.05, a
better relationship was observed between protein binding data and
chromatographically obtained hydrophobicity parameters C0 values. Conclusion.
Cellulose layers are easily available and cost effective sorbent to assess
hydrophobicity. Experimentally obtained data on ACE inhibitors hydrophobicity
and plasma protein binding estimation are important parameters in evaluating
bioavailability of these drugs.
Raw milk consumption and health

Published: February 2015

Contrary to the safe practices of milk pasteurization or sterilization, which
effectively reduce foodborne outbreaks incidence associated with raw milk and
dairy products use, outbreaks caused by such products continue to occur.
Despite this fact, a worldwide movement advocating for the rights of raw milk
and cheese selling and consumption, due to their specific nutritive
characteristics, has strengthened significantly in recent years. Traditional
agricultural manufacturers from Serbia still sell products related to
thermally unprocessed milk, such as cottage cheese and raw cream. In AP
Vojvodina during the period of 1981-2010 a total of 179 foodborne outbreaks
were reported, where the incriminated cause of the outbreak were milk or
diary. In 126 (70.39%) outbreaks, totaling 2276 sick individuals and one
casualty, it was confirmed that the incriminated food was from the group of
dairy products. In 48 instances (26.82%), bacteriological tests confirmed
that milk and dairy products were excluded as the outbreak causes, while in
another 5 (2.79%) outbreaks, microbiological analysis of food failed to
confirm any relation to the actual epidemiological instances. In some cases,
bacteriological testing of incriminated foods was not possible. In the cases
of outbreaks associated with the consumption of milk and dairy products,
traditional raw milk products were cited as being used. Consumption of
unpasteurized milk and cheese represents public health threat. National and
international rules ensuring use of safe products for human consumption have
to set rules of trade of thermally processed milk and products on the market.
Two Scales, Hybrid Model for Soils, Involving Artificial Neural Network and Finite Element Procedure
Authors: Krasiński Marcin , Lefik Marek
Published: February 2015

A hybrid ANN-FE solution is presented as a result of two level analysis of soils: a level of a laboratory sample and a level of engineering geotechnical problem. Engineering properties of soils (sands) are represented directly in the form of ANN (this is in contrast with our former paper where ANN approximated constitutive relationships). Initially the ANN is trained with Duncan formula (Duncan and Chang [2]), then it is re-trained (calibrated) with some available experimental data, specific for the soil considered. The obtained approximation of the constitutive parameters is used directly in finite element method at the level of a single element at the scale of the laboratory sample to check the correct representation of the laboratory test. Then, the finite element that was successfully tested at the level of laboratory sample is used at the macro level to solve engineering problems involving the soil for which it was calibrated.
Failure Criterion for Brick Masonry: A Micro-Mechanics Approach
Authors: Kawa Marek
Published: February 2015

The paper deals with the formulation of failure criterion for an in-plane loaded masonry. Using micro-mechanics approach the strength estimation for masonry microstructure with constituents obeying the Drucker-Prager criterion is determined numerically. The procedure invokes lower bound analysis: for assumed stress fields constructed within masonry periodic cell critical load is obtained as a solution of constrained optimization problem. The analysis is carried out for many different loading conditions at different orientations of bed joints. The performance of the approach is verified against solutions obtained for corresponding layered and block microstructures, which provides the upper and lower strength bounds for masonry microstructure, respectively. Subsequently, a phenomenological anisotropic strength criterion for masonry microstructure is proposed. The criterion has a form of conjunction of Jaeger critical plane condition and Tsai-Wu criterion. The model proposed is identified based on the fitting of numerical results obtained from the microstructural analysis. Identified criterion is then verified against results obtained for different loading orientations. It appears that strength of masonry microstructure can be satisfactorily described by the criterion proposed.
The Analysis of Soil Resistance During Screw Displacement Pile Installation
Authors: Krasinski Adam
Published: February 2015

The application of screw displacement piles (SDP) is still increasing due to their high efficiency and many advantages. However, one technological problem is a serious disadvantage of those piles. It relates to the generation of very high soil resistance during screw auger penetration, especially when piles are installed in non-cohesive soils. In many situations this problem causes difficulties in creating piles of designed length and diameter. It is necessary to find a proper method for prediction of soil resistance during screw pile installation. The analysis of screw resistances based on model and field tests is presented in the paper. The investigations were carried out as part of research project, financed by the Polish Ministry of Science and Higher Education. As a result of tests and analyses the empirical method for prediction of rotation resistance (torque) during screw auger penetration in non-cohesive subsoil based on CPT is proposed.
Particle Shape Effect on Macroscopic Behaviour of Underground Structures: Numerical and Experimental Study
Authors: Szarf Krzysztof , Combe Gael , Villard Pascal
Published: February 2015

The mechanical performance of underground flexible structures such as buried pipes or culverts made of plastics depend not only on the properties of the structure, but also on the material surrounding it. Flexible drains can deflect by 30% with the joints staying tight, or even invert. Large deformations of the structure are difficult to model in the framework of Finite Element Method, but straightforward in Discrete Element Methods. Moreover, Discrete Element approach is able to provide information about the grain-grain and grain-structure interactions at the microscale. This paper presents numerical and experimental investigations of flexible buried pipe behaviour with focus placed on load transfer above the buried structure. Numerical modeling was able to reproduce the experimental results. Load repartition was observed, being affected by a number of factors such as particle shape, pipe friction and pipe stiffness.
“I ask you, Mr. Mitchell, is the emergency over?”: Debating Day Nurseries in the Second World War
Authors: Pasolli Lisa
Published: February 2015

Abstract:

Analyses of the Dominion-Provincial Wartime Day Nurseries Agreement (wdna), most notably that by Ruth Roach Pierson, have been embedded mainly in histories of the mobilization and demobilization of women workers. Viewing the wdna entirely within this framework, however, does not capture the full complexity of the wartime child care story. The wdna sparked wide-ranging debates around the country about which mothers deserved day nursery services and what purposes these day nurseries were meant to serve. Social workers, welfare agencies, private day care providers, child welfare experts, and local politicians sought to define public child care as welfare policy for poor mothers, as a fixer of social ills, as educational innovation, and as a woman's right. This article suggests that the wdna was not just an anomaly in the history of twentieth-century child care but also a program that served to magnify the currents of child care politics that existed long before the war and that reverberated long after the war ended.
Health-related quality of life and happiness within an internal medicine residency training program: a longitudinal follow-up study
Authors: Sobhonslidsuk Abhasnee , Thakkinstian Ammarin , Satitpornkul Patchareeya
Published: February 2015

Purpose: While undergoing a hospital residency training program, residents often suffer anxiety and stress. This study aims to evaluate the change in health-related quality of life and happiness among internal medicine residents, and identify prognostic factors. Methods: Thirty-eight residents in the Ramathibodi Hospital internal medicine training program completed the World Health Organization Quality of Life-BREF and happiness Measures questionnaires at three time points: commencement, day 100, and the end of the second year of training. Confidence, expectations, anxiety, and general health were rated. Analyses were performed with mixed linear regression. Results: Financial problems were reported for 16 residents (42.1%). At baseline, most residents had moderate-to-very high confidence, expectations, and general health but also moderate-to-very high anxiety. The health-related quality of life score was highest in the social domain followed by the environmental, psychological, and physical domains. Their psychological, physical, social, and environmental scores significantly decreased after enrollment. Their happiness and general health scores were significantly reduced after enrollment. The training program duration was negatively associated with all domains. Residents with greater confidence had higher health-related quality of life scores in the physical, psychological, and environmental domains. Moreover, their general health was positively associated with the social and environmental domains. Conclusion: A reduction in health-related quality of life and happiness under the internal medicine residency program is reported. High confidence and good physical health may counterbalance the decline in health-related quality of life and happiness.
Early Radio Listening as Modernist Practice: Ambient Radio and the Aesthetic of Distraction
Authors: VanCour Shawn
Published: February 2015

Moving beyond radio's textual affinities with neighboring forms of modernist art, this essay explores the listening practices and modes of aural experience associated with the medium during its initial growth period in the United States from 1920 to 1930. Challenging emphases on private domestic space as the privileged site of radio reception, it argues that encounters with radio in public spaces outside the home were equally important for shaping popular experiences of broadcasting and linked the medium to a modern aesthetic of distraction. Public listening on city streets, in department stores, and at early trade shows positioned radio as an aural attraction that invited short bursts of attention and encouraged practices of acoustic flanerie. Listening in spaces of public recreation, by contrast, invited more sustained engagement but positioned radio as a background medium and object of secondary attention. These twin regimes of ambient radio and their associated modes of distracted listening echoed parallel tendencies observed by scholars of visual modernity, while indexing much broader structural and experiential shifts in early twentieth century urban life.
Contrary Regionalisms and Noisy Correspondences: The BBC in Northern Ireland circa 1949
Authors: Keane Damien
Published: February 2015

This essay examines the limits and possibilities of the mid-century broadcasting field in Northern Ireland, by attending to the dynamic interplay at the BBC's Belfast station of three competing regional formations: the political regionalism of the Northern Irish state; the cultural regionalism of a coterie of Northern Irish writers and intellectuals; and the broadcasting regionalism instituted as part of the BBC's policy of national programming. These contrary regionalisms each had different and, at times, competing criteria for what constituted particular and typical details of life in the North, and broadcasters had to negotiate the inexact correspondences among them with ears tuned to the political relations triangulated by Belfast, Dublin, and London. Beginning with a consideration of how broadcasters in Northern Ireland produced forms of mediated actuality both in and beyond the studio, the essay concludes with Sam Hanna Bell's This is Northern Ireland (1949), a feature that explores the tension of overspill and containment effected less by the partition of Ireland than by the contradictions inherent to the broadcasting field.
New Insights into Understanding Irreversible and Reversible Lithium Storage within SiOC and SiCN Ceramics
Authors: Graczyk-Zajac Magdalena , Reinold Lukas , Kaspar Jan , Sasikumar Pradeep , Soraru Gian-Domenico , Riedel Ralf
Published: February 2015

Within this work we define structural properties of the silicon carbonitride (SiCN) and silicon oxycarbide (SiOC) ceramics which determine the reversible and irreversible lithium storage capacities, long cycling stability and define the major differences in the lithium storage in SiCN and SiOC. For both ceramics, we correlate the first cycle lithiation or delithiation capacity and cycling stability with the amount of SiCN/SiOC matrix or free carbon phase, respectively. The first cycle lithiation and delithiation capacities of SiOC materials do not depend on the amount of free carbon, while for SiCN the capacity increases with the amount of carbon to reach a threshold value at ~50% of carbon phase. Replacing oxygen with nitrogen renders the mixed bond Si-tetrahedra unable to sequester lithium. Lithium is more attracted by oxygen in the SiOC network due to the more ionic character of Si-O bonds. This brings about very high initial lithiation capacities, even at low carbon content. If oxygen is replaced by nitrogen, the ceramic network becomes less attractive for lithium ions due to the more covalent character of Si-N bonds and lower electron density on the nitrogen atom. This explains the significant difference in electrochemical behavior which is observed for carbon-poor SiCN and SiOC materials.

Published: February 2015

Unlike other noise sources, which can be reduced or eliminated by different signal processing techniques, shot noise is an ever-present noise component in any imaging system. In this paper, we present an in-depth study of the impact of shot noise on time-of-flight sensors in terms of the error introduced in the distance estimation. The paper addresses the effect of parameters, such as the size of the photosensor, the background and signal power or the integration time, and the resulting design trade-offs. The study is demonstrated with different numerical examples, which show that, in general, the phase shift determination technique with two background measurements approach is the most suitable for pixel arrays of large resolution.
Silica micro/nanospheres for theranostics: from bimodal MRI and fluorescent imaging probes to cancer therapy
Authors: Walia Shanka , Acharya Amitabha
Published: February 2015

Nano-theranostics offer remarkable potential for future biomedical technology with simultaneous applications for diagnosis and therapy of disease sites. Through smart and careful chemical modifications of the nanoparticle surface, these can be converted to multifunctional tiny objects which in turn can be used as vehicle for delivering multimodal imaging agents and therapeutic material to specific target sites in vivo. In this sense, bimodal imaging probes that simultaneously enable magnetic resonance imaging and fluorescence imaging have gained tremendous attention because disease sites can be characterized quick and precisely through synergistic multimodal imaging. But such hybrid nanocomposite materials have limitations such as low chemical stability (magnetic component) and harsh cytotoxic effects (fluorescent component) and, hence, require a biocompatible protecting agent. Silica micro/nanospheres have shown promise as protecting agent due to the high stability and low toxicity. This review will cover a full description of MRI-active and fluorescent multifunctional silica micro/nanospheres including the design of the probe, different characterization methods and their application in imaging and treatment in cancer.
Chains of carbon atoms: A vision or a new nanomaterial?
Authors: Banhart Florian
Published: February 2015

Linear strings of sp1-hybridized carbon atoms are considered as a possible phase of carbon since decades. Whereas the debate about the stability of the corresponding bulk phase carbyne continues until today, the existence of isolated chains of carbon atoms has meanwhile been corroborated experimentally. Since graphene, as the two-dimensional sp2-bonded allotrope of carbon, has become a vast field, the question about the importance of one-dimensional carbon became of renewed interest. The present article gives an overview of the work that has been carried out on chains of carbon atoms in the past one or two decades. The review concentrates on isolated chains of carbon atoms and summarizes the experimental observations to date. While the experimental information is still very limited, many calculations of the physical and chemical properties have been published in the past years. Some of the most important theoretical studies and their importance in the present experimental situation are reviewed.

Authors: Mei Qinggang , Wang Chun , Yuan Weicheng , Zhang Guolin
Published: February 2015

A strategy for selective mono-, di- and tri-O-methylation of kaempferol, predominantly on the basis of selective benzylation and controllable deacetylation of kaempferol acetates, was developed. From the selective deacetylation and benzylation of kaempferol tetraacetate (1), 3,4′,5,-tri-O-acetylkaempferol (2) and 7-O-benzyl-3,4′5,-tri-O-acetylkaempferol (8) were obtained, respectively. By controllable deacetylation and followed selective or direct methylation of these two intermediates, eight O-methylated kaempferols were prepared with 51–77% total yields from kaempferol.

La naissance des systèmes philosophiques dans l'Antiquité : logique et histoire selon Jules Vuillemin1
Authors: Bénatouïl Thomas
Published: February 2015

Tout en définissant les systèmes philosophiques par des critères a priori , l’analyse de Vuillemin a l’ambition de s’appuyer sur l’histoire réelle de la philosophie pour les comprendre. Cet article examine cette articulation entre logique et histoire à propos de la question de la genèse de l’exigence de systématicité en Grèce antique. En s’appuyant sur des textes inédits déposés dans les Archives Vuillemin à Nancy, on montre que Vuillemin semble avoir évolué à propos des tentatives de contextualisation historique de la naissance de la philosophie, qu’il jugeait inutiles dans Nécessité ou Contingence, et à propos du rôle respectif du mythe et de la raison dans ce processus. On discute ensuite l’hypothèse principale de Vuillemin, à savoir le rôle moteur de l’axiomatique dans l’élaboration des systèmes antiques et on la compare avec l’hypothèse (issue de l’anthropologie historique de la Grèce) d’un rôle structurant des débats publics.
Politique et bonne gouvernance
Authors: Chomé Étienne
Published: February 2015

Cet article propose des stratégies pastorales mettant en œuvre le message du deuxième Synode pour l’Afrique, tenu en 2009, relatives à la politique et à la bonne gouvernance. Il s’inscrit dans la démarche d’une théologie pratique qui s’attache à traduire la pensée synodale en pistes opérationnelles pour les laïcs appelés à s’engager dans la Cité ; ce sont eux qui constituent la grande majorité du peuple de Dieu. L’A. prône la mobilisation collective et une organisation efficace des forces vives de l’Église. À partir des nouvelles sciences et expériences de gestion des conflits, il cherche à articuler davantage la théologie spirituelle de la paix développée par le Synode avec le combat non-violent contre les injustices. Il termine par des propositions concrètes concernant l’engagement solidaire du clergé aux côtés des laïcs qui travaillent concrètement au renforcement de l’État de droit.
