One-dimensional Schubert Problems with
Respect to Osculating Flags
Authors: Levinson Jake 
Published: December 2015

AbstractWe consider Schubert problems with respect to flags osculating the rational normal curve. These problems are of special interest when the osculation points are all real. In this case, for zerodimensional Schubert problems, the solutions are “ as real as possible”. Recent work by Speyer has extended the theory to the moduli space allowing the points to collide. This gives rise to smooth covers (ℝ), with structure and monodromy described by Young tableaux and jeu de taquin.In this paper, we give analogous results on one-dimensional Schubert problems over .Their(real) geometry turns out to be described by orbits of Schützenberger promotion and a related operation involving tableau evacuation. Over M 0,r, our results show that the real points of the solution curves are smooth.We also find a new identity involving “first-order” K-theoretic Littlewood-Richardson coefficients, for which there does not appear to be a known combinatorial proof.
Using Rituals for Intervention Refinement
Authors: Keller C. , Coe K. , Shaibi G. 
Published: December 2015

In this paper we propose a culture-based health promotion/disease prevention intervention model. This model, which is family-based, incorporates a life course perspective, which involves the identification of individual developmental milestones, and incorporates aspects of culture that have been widely used across cultures to influence behavior and mark important developmental transitions. Central among those cultural traits is the ritual, or rite of passage, which, for millennia, has been used to teach the skills associated with developmental task mastery and move individuals, and their families, through life stages so that they reach certain developmental milestones. Family rituals, such as eating dinner together, can serve as powerful leverage points to support health behavior change, and serve as unique intervention delivery strategies that not only influence behavior, but further strengthen families.

Published: December 2015

The present paper deals with assessing the level of contamination of green (n = 14) and black - fermented (n = 10) teas of different origins (country of origin) (China, India, Japan, Nepal and Taiwan), which are normally available in Slovakia. The contents of the studied contaminants (mercury, cadmium and lead) were observed in samples of dried teas and their infusions. The contaminant contents were investigated by atomic absorption spectrometry with Zeeman background correction and a graphite furnace GF-AAS (Cd, Pb). The total mercury content was analyzed by CV-AAS method. Concentrations of the studied contaminants in the dried tea samples were as follows: green tea: Hg: 0.0027 ±0.0010 mg.kg-1 (median ± standard deviation); Cd: 0.161 ±0.084 mg.kg-1, Pb: 0.875 ±0.591 mg.kg-1, black tea: Hg: 0.0022 ±0.0014 mg.kg-1, Cd: 0.397 ±0.077 mg.kg-1, Pb: 1.387 ±0.545 mg.kg-1. The contents of the contaminants in the tea infusions were as follows: green tea: Hg: 0.03 ±0.04 μg.L-1, Cd: 0.278 ±0.068 μg.L-1, Pb: 1.975 ±0.503 μg.L-1, black tea: Hg: 0.050 ±0.080 μg.L-1, Cd: 0.291 ±0.054 μg.L-1, Pb: 1.955 ±1.264 μg.L-1. According to the currently valid maximum limits for a particular contaminant in Slovakia, it can be stated that the health standards were not exceeded in any of the tea samples. The limit value of the lead content (2.0 mg.kg-1 DM) was exceeded (by 12.4%) only in one sample of the dried black tea from China (Yunnan - Golden Snow), however it is the limit value valid in China. The results of the analysis of 24 tea samples show that even regular consumption does not pose a health risk to consumers.

Authors: Gregova Edita , Šliková Svetlana , Hozlár Peter 
Published: December 2015

The protein diversity of 15 registered oat genotypes (Avena sativa L.) was examined. Acid-PAGE (acid polyacrylamide gel electrophoresis) of avenins and SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) of the glutelins were used for seed analyses of oat varieties. The result of this study indicated that the genotypes of oat cultivars could effectively be differentiated on the basis of polymorphism, detected between protein patterns. SDS-PAGE result revealed that glutelins presented a higher differentiation power than avenins and could be used as a rapid method for the identification of oat varieties in breeding programmes. Avenin protein band numbers and molecular weight ranged from 5 to 11, and 8 to 45 kDa, respectively. Genetic similarity analysis based on avenin protein ranged from 0,071 to 1. The tree-cluster analysis illustrates the distribution of varieties in two major groups. The first major group was large with eight varieties and following varieties were determined as identical: Vendelín-Zvolen and Prokop-Václav. The second group consisted of six varieties and Detvan-Hronec and Izak-Važec were identical pairs. The number of glutelin protein markers was 22. Genetic similarity coefficients resulted from comparisons by glutelin pattern and they ranged from 0,125 to 0,929 all oat varieties were different from each other. Two Slovakian varieties Izak and Važec from Breeding Station Viglaš-Ptruša with similarity value 92,9% were grouped with variety Vendelin. Two varieties Kanton and Viliam with similiarity value 92% were grouped with Prokop and Valentin. All analysed cultivars could be distinguished by their glutelin pattern and will be useful in oat breeding process.

Published: December 2015

In the present work, the effect of the Abies alba essential oil in two different concentrations on oxidative stability of chicken thigh muscles during chilled storage was investigated. In the experiment were chickens of hybrid combination Cobb 500 after 42 days of the fattening period slaughtered. All the broiler chickens were fed with the same feed mixtures and were kept under the same conditions. The feed mixtures were produced without any antibiotic preparations and coccidiostatics. After slaughtering was dissection obtained fresh chicken thigh with skin from left half-carcass which were divided into five groups (n = 5): C - control air-packaged group; A1 - vacuum-packaged experimental group; A2 - vacuum-packaged experimental group with thylenediaminetetraacetic acid (EDTA) solution 1.50% w/w; A3 - vacuum-packaged experimental group with Abies alba oil 0.10% v/w and A4 - vacuum-packaged experimental group with Abies alba oil 0.20% v/w. The Abies alba essential oil was applicate on ground chicken things and immediately after dipping, each sample was packaged using a vacuum packaging machine and storage in refrigerate at 4 ±0.5 °C. Thiobarbituric acid (TBA) value expressed in number of malondialdehyde was measured in the process of first storage day of 1st, 4th, 8th, 12th and 16th day after slaughtering and expressed on the amount of malondialdehyde (MDA) in 1 kg sample. The treatments of chicken things with Abies alba essential oil show statistically significant differences between all testing groups and control group, where higher average value of MDA measured in thigh muscle of broiler chickens was in samples of control group (0.4380 mg.kg-1) compared to experimental groups A1 (0.124 mg.kg-1), A2 (0.086 mg.kg-1), A3 (0.082 mg.kg-1) and A4 (0.077 mg.kg-1) after 16-day of chilled storage. Experiment results show that the treatment of chicken thigh with Abies alba essential oil positively influenced on the reduction of oxidative processes in thigh muscles during chilling storage and use of essential oil is one of the options increase shelf life of fresh chicken meat.

The aim of the present study was analysed chemical and physical parameters of dried salted pork ham and neck. Dry-cured meat is a traditional dry-cured product obtained after 12 - 24 months of ripening under controlled environmental conditions. Ham and neck was salted by nitrite salt mixture during 1 week. Salted meat products were dried at 4 °C and relative humidity 85% 1 week after salting. The quality of dry-cured meat is influenced by the processing technology, for example length of drying and ripening period. The average moisture of dried salted pork ham was 63.77% and dried salted pork neck was 59.26%. The protein content was 24.87% in dried salted pork ham and significantly lower (20.51%) in dried salted pork neck. The value of intramuscular fat in dried salted pork ham was 4.97% and 14.40% in dried salted pork neck. The salt content was 5.39% in dried salted pork ham and 4.83% in dried salted pork neck. The cholesterol content was 1.36 g.kg-1 in dried salted pork ham and significant lower in dried salted pork neck (0.60 g.kg-1). The value of lightness was 44.36 CIE L* in dried salted pork ham and significantly lower in dried salted pork neck (40.74 CIE L*). The pH value was 5.84 in dried salted pork ham and 5.80 in dried salted pork neck. The shear work was 9.99 kg.s-1 in dried salted pork ham and 6.34 in dried salted pork neck. The value of water activity (aw) was 0.929 in dried salted pork ham and similar 0.921 in dried salted pork neck.
Assessing expression of TAS2R16 receptor on the tongue of elderly persons
Authors: Fekete Tomáš , Židek Radoslav , Maršálková Lenka 
Published: December 2015

In conducted study, we assessed expression of TAS2R16 receptor gene on the tongue of elderly persons. The TAS2R16 receptor belongs to family of G-protein coupled bitter taste receptors and is expressed in type 2 taste cells, which are a part of taste buds. The taste buds are distributed across the tongue's surface on the specialised structures called papillae. The TAS2R16 receptor mediates bitter taste in response to β-glucopyranosides such as salicin. The purpose of conducted study was to examine, whether the ageing process influence gene expression and hence the perception of taste at the molecular level. Ageing process is often related to either decreased or total lost perception of taste qualities. It is due to physiological changes in the oral cavity. The changes in taste cell membranes involve altered function of ion channels and receptors, which ultimately lead to decreased tasting ability of elderly people. In addition, various causes, such as oral and systemic diseases, drug administration, lifestyle (i.e. smoking) and some oral conditions (wearing dentures, dental caries and coated tongue), may extracerbate this issue. Loss of taste may become a large factor in reduction of appetite, which may lead to malnutrition. To accomplish the objective of this study, we recruited ten elderly persons. One 25-year old human was used as calibrator. We used non-invasive scrapping method for collecting taste cells from fungiform papillae of each subject. A multiplex TaqMan real-time PCR was performed to amplify cDNA of TAS2R16 and PGK1 genes, whereas the last one served as housekeeping gene. The TAS2R16 gene expression for elderly persons relative to that of young one was calculated according to the 2-ΔCT formula. Results pointed out to increased expression of TAS2R16 gene by 2-fold in 5th and 8th seniors. It is assumed that they perceive more intense bitterness from salicin at the molecular level than 25-year old person. The 2nd, 3rd, 7th and 10th elderly persons have had decreased expression level about 70%, whereas in case of 6th one that was even about 90%. It is supposed that these subjects, in particular last one, respond to salicin very weakly. This data may show evidence of almost total loss of taste. The causes and consequences are discussed in more detail.
The Five Essential Roles of Assessment Practitioners

Published: December 2015

Abstract
Assessment practitioners are tasked with a range of responsibilities from enhancing teaching and learning to improving institutional effectiveness and providing quality assurance, yet little is known about the roles and related skill sets needed to undertake these tasks. Through an examination of job postings coupled with a review of the current literature, one-on-one interviews with four leaders in the field of assessment and an exploration of our own professional experience, this paper proposes a framework of five essential roles for assessment practitioners including assessment/method expert, narrator/translator, facilitator/guide, political navigator and visionary/believer.
The Legacy of Fakhreddine II—Renaissance Prince of Mount Lebanon
Authors: Scham Sandra A. 
Published: December 2015

ABSTRACT
The Druze Prince Fakhreddine el Maani II is acknowledged by some historians as one of Lebanon's greatest historical figures. He was also a master builder who, inspired by a sojourn in Renaissance Italy, introduced a new architectural style to the region combining both traditional Levantine and European design elements. Today, only a few of these structures have survived to attest to his life and his leadership.
Current Concepts and New Insights from Mouse Models of Mammary Tumors on Epithelial Mesenchymal Transition and its Synergy with Mutant p53
Authors: A. Piersigilli  , A. D. Borowsky  , Q. Chen  , N.E. Hubbard  , R.D. Cardiff  
Published: December 2015

Epithelial Mesenchymal Transition (EMT) is the transdifferentiation of epithelial cells into a mesenchymal phenotype. This process occurs during embryogenesis but also in wound healing and in tumors. The neoplastic EMT is characterized by variably complete shedding of epithelial architectural features and acquisition of mesenchymal traits. In immunohistochemistry a variable coexpression of cytokeratins, vimentin or alpha-smooth muscle actin with loss of E-cadherin and other interepithelial adhesion molecules is characteristic. Such transition is associated with mutations both at the genetic (somatic) and epigenetic levels and is believed to confer a more advantageous phenotype for local and distant spread of cancer cells. Mammary carcinoma can exhibit EMT features in humans and mice and it tends to occur more frequently in women with tumors bearing a worse prognosis such as the claudin low subtype within the triple negative cancer. Missense mutation of TP53 is one of the most common mutations in cancer and it is frequently found in EMT tumor types, often with a more aggressive behavior. The current literature and survey of our mouse EMT cases in the Genomic Pathology Center image archives demonstrate a synergy between p53 and EMT that is independent of the initiating oncogene. However, p53 mutation is not sufficient or causal for EMT. Moreover, despite the local malignant behavior, processes such as spontaneous metastases and Mesenchymal Epithelial Transition (MET) appear not to be as frequent and obvious as previously hypothesized.
« Je leur dis que j’ai deux mamans ? » : carrières de (non-)publicisation de l’homoparentalité à l’école en France
Authors: Olivier Alice 
Published: December 2015

Si la recherche s’est intéressée à la formation des familles homoparentales et au développement de leurs enfants, très peu de travaux se sont interrogés sur la manière dont ces derniers gèrent leur situation familiale en milieu scolaire. Pourtant, l’école est vectrice d’hétéronormativité, ce qui soulève de nombreuses questions quant aux attitudes que ces enfants y adoptent : comment y font-ils état de leur situation familiale ? À partir d’entretiens menés en France auprès de 13 filles et garçons âgés de 10 à 19 ans et issus de familles homoparentales de configurations diverses, j’analyse la « (non-)publicisation » de l’atypisme familial dans sa dimension temporelle en la considérant comme une « carrière » séquencée par les différents paliers scolaires traversés. Correspondant à des contextes normatifs bien différents, ces paliers impliquent des manières précises et distinctes de percevoir et donc de publiciser sa famille. Ainsi, l’école élémentaire (de 6 à 11 ans environ) est un espace peu normé par les groupes de pairs dans lequel l’homoparentalité n’est pas perçue comme un stigmate, ce qui explique une large publicisation de la situation familiale. Au collège (de 11 à 15 ans) en revanche, les normes des groupes de pairs se renforcent et confèrent un caractère stigmatisant à cette situation, qui est alors publicisée auprès d’un petit nombre de camarades choisis et masquée à d’autres. Au lycée (de 15 à 18 ans) enfin, l’homoparentalité peut rester perçue comme un stigmate, mais celui-ci est souvent renversé dans une publicisation active de la situation familiale.
Les atermoiements du droit français dans la reconnaissance des familles formées par des couples de femmes
Authors: Brunet Laurence 
Published: December 2015

Les juges français sont depuis plusieurs années régulièrement saisis, de la part de couples de femmes, de demandes visant à reconnaître une place à la mère « sociale », par opposition à la mère légale qui est celle ayant accouché de l’enfant. Comment les juges répondent-ils à ces requêtes ? La loi du 17 mai 2013 a ouvert le mariage aux couples de même sexe et autorise en conséquence l’adoption de l’enfant par l’épouse de la mère légale. Mais avant même le vote de cette loi, la jurisprudence avait oeuvré en faveur de la reconnaissance d’un quasi-statut pour la mère « sociale », pendant comme après la fin de la vie commune de couple. Plus d’un an après la première consécration légale en France de la famille homoparentale, un premier bilan mérite d’être dressé.
Perpendicular magnetic tunnel junction with enhanced anisotropy obtained by utilizing an Ir/Co interface
Authors: Yakushiji Kay , Kubota Hitoshi , Fukushima Akio , Yuasa Shinji 
Published: December 2015

Abstract
A highly scalable perpendicularly magnetized storage layer of a spin-torque-switching magnetic random-access memory (STT-MRAM) was developed. This storage layer attains a perpendicular magnetic anisotropy (PMA) of above 0.9 erg/cm2 at a thickness of 2 nm. Such high PMA is suitable for pushing STT-MRAM technology beyond the 20 nm node. The key was to realize dual interfacial PMA at both the Ir/Co and FeB/MgO interfaces in the united structure of the storage layer. While a high PMA was retained, a high magnetoresistance ratio (100%) and a low resistance–area product (3.0 Ω µm2) were also achieved.

ImportanceObesity is associated with numerous psychosocial complications, making psychiatric safety a consideration for treating people with obesity. Few studies have investigated the psychiatric safety of newly available antiobesity medications.ObjectiveTo evaluate the psychiatric safety of subcutaneous semaglutide, 2.4 mg, once weekly in people without known major psychopathology.Design, Setting, and ParticipantsThis post hoc analysis of pooled data from the randomized, double-blind, placebo-controlled, multicenter phase 3a STEP 1, 2, and 3 trials (68 weeks; 2018-2020) and phase 3b STEP 5 trial (104 weeks; 2018-2021) included adults with overweight or obesity; STEP 2 participants also had type 2 diabetes. Trial designs have been published previously.InterventionsSemaglutide, 2.4 mg, vs placebo.Main Outcomes and MeasuresDepressive symptoms and suicidal ideation/behavior were assessed using the Patient Health Questionnaire (PHQ-9) and Columbia–Suicide Severity Rating Scale, respectively. Psychiatric and nervous system disorder adverse events were investigated.ResultsThis analysis included 3377 participants in the STEP 1, 2, and 3 trials (2360 women [69.6%]; mean [SD] age, 49 [13] years) and 304 participants in STEP 5 (236 women [77.6%]; mean [SD] age, 47 [11] years). In the STEP 1, 2, and 3 trials, mean (SD) baseline PHQ-9 scores for the semaglutide, 2.4 mg, and placebo groups were 2.0 (2.3) and 1.8 (2.3), respectively, indicating no/minimal symptoms of depression. PHQ-9 scores at week 68 were 2.0 (2.9) and 2.4 (3.3), respectively; the estimated treatment difference (95% CI) between groups was −0.56 (−0.81 to −0.32) (P &amp;lt; .001). Participants treated with semaglutide vs placebo were less likely to shift (from baseline to week 68) to a more severe category of PHQ-9 depression (odds ratio, 0.63; 95% CI, 0.50-0.79; P &amp;lt; .001). Based on the Columbia–Suicide Severity Rating Scale, 1% or fewer of participants reported suicidal ideation/behavior during treatment, with no differences between semaglutide, 2.4 mg, and placebo. Psychiatric disorder adverse events were generally balanced between groups. Similar results were observed in STEP 5.Conclusions and RelevanceThe results of this post hoc analysis suggest that treatment with semaglutide, 2.4 mg, did not increase the risk of developing symptoms of depression or suicidal ideation/behavior vs placebo and was associated with a small but statistically significant reduction in depressive symptoms (not considered clinically meaningful). People with obesity should be monitored for mental health concerns so they can receive appropriate support and care.Trial RegistrationClinicalTrials.gov Identifiers: STEP 1 (NCT03548935), 2 (NCT03552757), 3 (NCT03611582), and 5 (NCT03693430)
