Published: March 2015

Abstract

Background
This work is part of a wide scientific project finalized to characterize the Sicilian pottery productions from Greek to Roman Age. In this prospective, local reference groups have been analysed in order to create a database of the circulation and production centres in Sicily during this period. In this framework, a set of 28 waste pottery fragments (III-II century B.C.) from a pit found during excavations at the fortification of Adrano (Sicily) have been studied.
Characterization of the samples has been obtained by macroscopic, petrographic (OM), mineralogical (XRD) and chemical (XRF) analyses.

Results
Macroscopic analysis of the studied potteries has allowed to distinguish four groups on the basis of grain size, porosity and clay paste color. Petrographic and mineralogical analysis, carried out on a selection of representative samples have allowed us to obtain useful information on the production technology of the studied samples. Moreover, information about raw materials and provenance of clay sediments has been obtained by comparing chemical data of the analysed samples with locally outcropping clay sediments reference data. Finally, chemical results on Adrano potteries have been compared with kiln wastes from Siracusa and Gela.

Conclusions
The aim of the present work is to obtain fabric characterizations and technological information on a local reference group of ceramic specimens manufactured in Adrano (Sicily). Petrographic and mineralogical results allow us to esteem high firing temperature suggesting a good technological level of local production; in addition, chemical data suggest a local provenance of raw materials used in the production of the studied samples. The comparison with local production from Siracusa and Gela highlights several differences in the use of raw material and in the technological levels achieved in the different sites, over time. Therefore, this work provides a valuable contribution in defining the local scenario of ceramic production in South-Eastern Sicily during the Hellenistic Age and in producing local reference groups in the petro-archaeometric studies of archaeological potteries.
Mitogen-Activated Protein Kinase 8 (MAP3K8) Mediates the Signaling Pathway of Estradiol Stimulating Progesterone Production Through G Protein-Coupled Receptor 30 (GPR30) in Mouse Corpus Luteum

AbstractThe corpus luteum (CL) is a transient endocrine gland developed from the ovulated follicles, and the most important function is to synthesize and secrete progesterone (P4), a key hormone to maintain normal pregnancy and estrous cycle in most mammals. It is known that estrogen has a vital role in stimulating P4 synthesis in CL, but it still remains unclear about the mechanism of estradiol (E2) regulating P4 production in CL. Our results here first show that all of the CL cells express MAPK 8 (MAP3K8), and the MAP3K8 level is much higher at the midstage than at the early and late stages during CL development. The further functional studies show that the forced inhibition of endogenous MAP3K8 by using MAP3K8 small interfering RNA and MAP3K8 signaling inhibitor (MAP3K8i) in the luteal cells significantly block the P4 synthesis and neutralize the enhancing effect of E2 on P4 production in the CL. In addition, our results here demonstrate that the stimulating effect of E2 on P4 synthesis relies on the estrogen no-classical protein-coupled receptor 30, and MAP3K8 is involved in mediating the protein-coupled receptor 30signaling of E2 affecting P4 synthesis via stimulating ERK phosphorylation. These novel findings are critical for our understanding the ovary physiology and pathological mechanism.
Synthesis of Common-sized Heterocyclic Compounds by Intramolecular Cyclization over Halide Cluster Catalysts
Authors: Nagashima Sayoko , Sasaki Tomoaki , Kamiguchi Satoshi , Chihara Teiji 
Published: March 2015

Abstract
Five- to seven-membered common-sized heterocyclic compounds containing an oxygen, sulfur, or nitrogen were synthesized by the intramolecular condensation of α,ω-hydroxy, mercapto, or amino alkanes, respectively, over halide cluster complexes as a thermally stable molecular solid weak acid catalyst in the gas phase at temperatures ≥150 °C. From ω-mercapto and ω-amino alcohols, cyclic sulfides and amines were obtained, respectively. These unimolecular reactions are thermodynamically and kinetically favored.
Effect of Hydrogen on the Orientation of Cinchonidine Adsorbed on Platinum: An ATR-SEIRAS Study
Authors: Motobayashi Kenta , Tomioka Ryota , Uchida Taro , Osawa Masatoshi 
Published: March 2015

Abstract
The orientation of cinchonidine (CD) adsorbed on a Pt surface, a model system of enantioselective catalysis for hydrogenation reactions, is studied in 1,2-dichloroethane by in situ surface-enhanced infrared absorption spectroscopy in attenuated total reflection configuration. The quinoline (QN) moiety of CD is shown to be reoriented from a π-bonded nearly parallel orientation to an N-bonded upright one by bubbling the solution with H2. The origin of the reorientation is ascribed to the repulsive interaction of a QN π-orbital and the negative surface charge induced by dissociative adsorption of H2 and hydrogenation of the vinyl moiety.

Published: March 2015

Purpose: To evaluate the reproducibility and reliability of optical coherence tomography scans obtained using the time domain (TD-OCT) StratusTM OCT, and the Spectral Domain (SD-OCT) SpectralisTM and CirrusTM OCT devices before and after manual correction in eyes with either Neovascular (NV-AMD) or Non-Neovascular (NNV-AMD) age-related macular degeneration.Design: Prospective observational study.Methods:Setting: University-based retina practice.Patients: Thirty-six patients (50 eyes) with NV-AMD or NNV-AMD.Procedure: OCT scans were taken simultaneously using one TD-OCT and two SD-OCT devices.Main Outcome Measures: Macular thickness measurements were assessed before and after correction of the algorithm by constructing Bland-Altman plots for agreement and calculating intraclass correlation coefficients (ICCs) and coefficients of repeatability (COR) to evaluate intraclass repeatability.Results: Spectralis had the highest number of images needing manual correction. All machines had high ICCs, with Spectralis having the highest. Also, Bland-Altman plots indicated that there was low agreement between Cirrus™ and Stratus™, Spectralis™ and Stratus™, while there was good agreement between the Cirrus™ and Spectralis™. The CORs were lowest for SpectralisTM and similar and higher for CirrusTM and StratusTM. Agreement, CORs, and ICCs generally improved after manual correction, but only minimally. Conclusion: Agreement is low between devices, except between both SD-OCT machines. Manual correction tends to improve results.
Public policies in a regulated entrepreneurial setting
Authors: Marcus Alfred A. , Cohen Susan K. 
Published: March 2015

AbstractThe existing literature in public policy has commented mostly on mature and established businesses, leaving the relationships between entrepreneurial businesses and public policies less explored. Relying on qualitative research methods and quantitative surveys, we examine how managers in an intensively regulated entrepreneurial setting assessed the desirability of public policies. We show that managers in the regulated energy efficiency and renewable (EERE) business sector in the 1990s tended to view public policies favorably only if they lacked control over the business environment. The less control they perceived they had over the business environment, the more favorably they tended to view public policies. Our findings suggest that managers in a regulated entrepreneurial setting tend to view public policies as substitutes for their efforts to control their business environment, not as complements, as studies of mature and established companies in regulated settings commonly find. However, we also find some evidence to suggest these perceptions may evolve, as a business experiences greater success attracting customers.

Published: March 2015

Abstract
This paper deals with the determination of the capillary pore-size distribution (CPSD) and equilibrium moisture content (EMC) of untreated and thermally modified (TM) Norway spruce [Picea abies (L.) Karst.] by means of the pressure plate technique (PPT). Desorption experiments were conducted at very high values of relative humidity (RH) in the range between 99.2% and 100%. The thermal modification of spruce results in an alteration of the CPSD, owing to the formation of intercellular cracks in the middle lamella, as a result of cell-wall compression. The desorption curves for both untreated and TM spruce show an extremely upward bend at 99.97% RH. This step reflects an EMC of 38.1% for untreated spruce and 33.8% for TM spruce. None of the samples shrunk during the PPT measurements. Following desorption experiments at 97.4% RH, all samples shrunk. This step reflects an EMC of 27.9% for untreated spruce and 21.7% for TM spruce.

Published: March 2015

AbstractIn order to predict correctly stress-strain curve for tensile tests at elevated and cooling temperatures, a modification of a Johnson–Cook (J-C) model and a new method to determine (J-C) material parameters are proposed. A MATLAB tool is used to determine material parameters by fitting a curve to follow Ludwick and Voce's hardening law at various elevated temperatures. Those hardening law parameters are then utilized to determine modified (J-C) model material parameters. The modified (J-C) model shows the better prediction compared to the conventional one. An FEM tensile test simulation based on the isotropic hardening model for metal sheet at elevated temperatures was carried out via a user-material subroutine, using an explicit finite element code. The simulation results at elevated temperatures were firstly presented and then compared with the measurements. The temperature decrease of all elements due to the air cooling process was then calculated when considering the modified (J-C) model and coded to VUMAT subroutine for tensile test simulation. The modified (J-C) model showed the good comparability between the simulation results and the corresponding experiments.

Abstract

Introduction: To search for microstructural lesions of normal-appearing cerebral white matter surrounding a tumor or a vascular lesion, after single-fraction stereotactic Gamma Knife (GK) radiosurgery.

Methods: In 43 patients with different brain lesions, magnetic resonance including diffusion tensor imaging (DTI) was performed before and after GK radiosurgery and change of parameters was measured in areas surrounding the lesion.

Results: Outside the lesion, there was an increase in mean diffusivity (MD) and radial diffusivity (RD) between 2.1% and 3.4% in the 15–10 Gy and in the 10–5 Gy perilesional isodose volumes, which reached statistical significance (paired t-test) for the MD and RD values in both volumes (P≤0.05) and correlated to the delay from treatment (P<0.01 resp. P<0.05). The only significant change in the fractional anisotropy values was a decrease in the 10–5 Gy isodose volume (P≤0.01), which correlated to the radiation dose applied (P<0.05).

Conclusion: We report some minor, but nevertheless significant changes in DTI parameters in normal-appearing perilesional brain tissue after GK radiosurgery progressing with time, which partially may be induced by the radiation itself and partially may be due to indirect effects of lesion reactions to the radiation. Follow-up studies are necessary for further characterization of these changes and assessment of their time course.

Published: March 2015

AbstractA new compound was synthesized from 2-hydroxy-1,2,3-propanetricarboxylic acid (citric acid) and diethylene glycol (DEG). Compound, tris(hydroxydietylene)-2-hydroxypropane-1,2,3-tricarboxylate (THT) rated properties in terms of suitability for the rigid polyurethane-polyisocyanurate (PUR-PIR). Rated properties of THT eg., acid number, density, pH, solubility. The resulting product was characterized by hydroxyl number 405.2 mg KOH/g and viscosity 4879.7 mPa·s. Compound used to foams in amounts of from 0.1 equivalents to 0.5 equivalents instead of Rokopol RF551. The results of rigid foams showed that the amount of THT in the foam significantly affects the compressive strength of foams. Its amount does not affect the apparent density of foam, retention and thermal conductivity. The foams are characterized by small values of fragility.

Published: March 2015

AbstractElucidating functions of commensal microbial genes in the mammalian gut is challenging because many commensals are recalcitrant to laboratory cultivation and genetic manipulation. We present Temporal FUnctional Metagenomics sequencing (TFUMseq), a platform to functionally mine bacterial genomes for genes that contribute to fitness of commensal bacteria in vivo. Our approach uses metagenomic DNA to construct large‐scale heterologous expression libraries that are tracked over time in vivo by deep sequencing and computational methods. To demonstrate our approach, we built a TFUMseq plasmid library using the gut commensal Bacteroides thetaiotaomicron (Bt) and introduced Escherichia coli carrying this library into germfree mice. Population dynamics of library clones revealed Bt genes conferring significant fitness advantages in E. coli over time, including carbohydrate utilization genes, with a Bt galactokinase central to early colonization, and subsequent dominance by a Bt glycoside hydrolase enabling sucrose metabolism coupled with co‐evolution of the plasmid library and E. coli genome driving increased galactose utilization. Our findings highlight the utility of functional metagenomics for engineering commensal bacteria with improved properties, including expanded colonization capabilities in vivo.

The Genus Bilabrella Lindl. (Orchidaceae, Habenariinae): General Characteristic and Research History of The Genus
Authors: Kras Marta , Szlachetko Dariusz L. 
Published: March 2015

Abstract
The genus Bilabrella (Habenarinae, Orchidaceae) was described by Lindley in 1834, but within next years, different authors incorporated it as the section of the genus Habenaria Willd. From 2003, Szlachetko and Kras stated that there were no grounds for distinguishing the sections Bilabrellae and Replicatae. They restored the genus Bilabrella, transfering to it 93 species from the section Replicatae and four species new to science were described. The poor condition of the old plant materials, the lack of some type specimens for many species described by Schlechter and problems with a series of transitional forms between some species are only few reasons, why the revision of the genus has not been published so far. Bilabrella comprises orchids found in Sub-Saharan Africa, Madagascar and neighbouring islands. Bilabrella differs from other Habenariinae in its unique combination of features
