Future sea level change from Antarctica's Lambert‐Amery glacial system

Future global mean sea level (GMSL) change is dependent on the complex response of the Antarctic ice sheet to ongoing changes and feedbacks in the climate system. The Lambert‐Amery glacial system has been observed to be stable over the recent period yet is potentially at risk of rapid grounding line retreat and ice discharge given that a significant volume of its ice is grounded below sea level, making its future contribution to GMSL uncertain. Using a regional ice sheet model of the Lambert‐Amery system, we find that under a range of future warming and extreme scenarios, the simulated grounding line remains stable and does not trigger rapid mass loss from grounding line retreat. This allows for increased future accumulation to exceed the mass loss from ice dynamical changes. We suggest that the Lambert‐Amery glacial system will remain stable or gain ice mass and mitigate a portion of potential future sea level rise over the next 500 years, with a range of +3.6 to −117.5 mm GMSL equivalent.
Scaffolds in Periodontal Regeneration

Periodontal tissue engineering requires triad of cells, inductive component and a scaffold on which growth can occur. Previously periodontal treatment was aimed to selectively repopulate the defect site with cell that has capability to regenerate lost tissue by using the concept of guided tissue regeneration. However, this technique is not always possible. Use of scaffolds that can also deliver cells required for regeneration to occur is relatively a newer concept. A biomaterial is defined as a nonviable material used in a medical device, intended to interact with biological systems. For a device to be effective, it has to meet certain criteria based on organ and tissue properties and specific goals. Every material available in market has its own advantages and disadvantages. This review will mainly focus on the devices along with the advancement taking place related to cell delivery system.
Synthesis, characterization, and structure of a new cobalt(II) Schiff-base complex with quinoxaline- 2-carboxalidine-2-amino-5-methylphenol

The mononuclear cobalt(II) complex [CoL2] · H2O (where HL is quinoxaline-2-carboxalidine-2-amino-5-methylphenol) has been prepared and characterized by elemental analysis, conductivity measurement, IR, UV-Vis spectroscopy, TG−DTA, and X-ray structure determination. The crystallographic study shows that cobalt(II) is distorted octahedral with each tridentate NNO Schiff base in a cis arrangement. The crystal exhibits a 2-D polymeric structure parallel to [010] plane, formed by O−H ··· N and O−H ··· O intermolecular hydrogen bonds and π−π stacking interactions, as a racemic mixture of optical enantiomers. The ligand is a Schiff base derived from quinoxaline-2-carboxaldehyde.
Do Corporate Governance Disclosures Matter for Bank Cost of Capital? Empirical Evidence from Accounting Statements of Egyptian Banks

The purpose of this study is to examine the association between the quality of bank governance mechanisms disclosed in bank annual reports and cost of capital. The Egyptian banking sector has undergone a series of legislative reforms starting with the issuance of the 2003 banking law. The law incorporates the guidelines of the Basel Accords and governance principles, and was declared a major step forward into facing global banking competition and driving financial growth in Egypt. We create two multivariate cross-sectional, time-series regression models to test this relation. Our main results show that there is a highly significant relation between bank governance disclosures and cost of capital. Banks with reported large board size and more executive directors on board are able to obtain finance from cheaper resources. This indicates that cost of equity of Egyptian banks is not just related to accounting performance and risk but also related to how well a bank is governed . Furthermore, the cost of deposits decreases significantly for banks reporting better governance mechanisms.
Glacial-to-interglacial changes in nitrate supply and consumption in the subarctic North Pacific from microfossil-bound N isotopes at two trophic levels

Reduced nitrate supply to the subarctic North Pacific (SNP) surface during the last ice age has been inferred from coupled changes in diatom-bound δ15N (DB-δ15N), bulk sedimentary δ15N, and biogenic fluxes. However, the reliability of bulk sedimentary and DB-δ15N has been questioned, and a previously reported δ15N minimum during Heinrich Stadial 1 (HS1) has proven difficult to explain. In a core from the western SNP, we report the foraminifera-bound δ15N (FB-δ15N) in Neogloboquadrina pachyderma and Globigerina bulloides, comparing them with DB-δ15N in the same core over the past 25 kyr. The δ15N of all recorders is higher during the Last Glacial Maximum (LGM) than in the Holocene, indicating more complete nitrate consumption. N. pachyderma FB-δ15N is similar to DB-δ15N in the Holocene but 2.2‰ higher during the LGM. This difference suggests a greater sensitivity of FB-δ15N to changes in summertime nitrate drawdown and δ15N rise, consistent with a lag of the foraminifera relative to diatoms in reaching their summertime production peak in this highly seasonal environment. Unlike DB-δ15N, FB-δ15N does not decrease from the LGM into HS1, which supports a previous suggestion that the HS1 DB-δ15N minimum is due to contamination by sponge spicules. FB-δ15N drops in the latter half of the Bolling/Allerod warm period and rises briefly in the Younger Dryas cold period, followed by a decline into the mid-Holocene. The FB-δ15N records suggest that the coupling among cold climate, reduced nitrate supply, and more complete nitrate consumption that characterized the LGM also applied to the deglacial cold events.
A comparative study of genotoxicity and oxidative stress before and after using lemon balm and cinnamon in subjects exposed to Nickel Welding Fumes

By producing reactive oxygen and nitrogen species, metal-induced toxicity and carcinogenicity alter DNA bases, increase lipid peroxidation, and change calcium and sulfhydryl homeostasis. The purpose of the study was to investigate putative effects of Lemon balm and Cinnamomum zeylanicum on the blood markers of welding workers. We measured nickel and chromium levels, biochemical parameters, blood oxidative stress markers, total antioxidant capacity (TAC), Myeloperoxidase (MPO), lipid peroxidation (LPO), and DNA damage. The study was conducted on 55 male workers who worked in an industrial subjects exposed to Nickel Welding Fumes. The participants were administered Lemon balm and Cinnamon extract infusion 1.5 (0.12 extract) and 0.25(0.013 extract) g/100 mL, respectively, they have drunken twice a day for 30 days at 7:00 AM and 2:00 PM every day. In order to analyze the achieved data, paired t-test and Pearson correlation coefficient have been used. After using the extract infusion, a significant increase revealed in TAC (p= 0.007). Also, administration of infusion decreased DNA damage but it was not statistically significant. After administration of infusion, a decrease in LPO and MPO were observed (p= 0.014, p=0.000 respectively). Also there is positive correlation between ALP and Ni with 8-oH-dG and also, between Ni and TAC. The results indicate that using infusion causes to raise in a TAC and reduce in DNA damage.
THRESHOLDS AND SMOOTH TRANSITIONS IN VECTOR AUTOREGRESSIVE MODELS

This survey focuses on two families of nonlinear vector time series models, the family of Vector Threshold Regression models and that of Vector Smooth Transition Regression models. These two model classes contain incomplete models in the sense that strongly exogeneous variables are allowed in the equations. The emphasis is on stationary models, but the considerations also include nonstationary Vector Threshold Regression and Vector Smooth Transition Regression models with cointegrated variables. Model specifi? cation, estimation and evaluation is considered, and the use of the models illustrated by macroeconomic examples from the literature.
Extent of Electronic Prescribing Implementation as Perceived by MCO Pharmacy Managers

(82%) had discussed implementing electronic prescribing, 11 (25%) had developed a plan, but only seven (16%) had actually implemented electronic prescribing. This distribution was observed regardless of MCO type or membership size or membership type. Provider resistance appeared to be rated as the highest barrier by those who considered implementation of electronic prescribing not feasible. In contrast, responders who had the opportunity to implement electronic prescribing appeared to rate the investment requirement as the highest barrier. CONCLUSIONS: The extent of electronic prescribing implementation by MCOs might be minimal. Barriers to implementation may appear overwhelming at the early stages of discussion, but may change as the implementation process progresses.
High density limit in reversed field pinches

The fusion triple product depends on density, which is therefore a key parameter for the future fusion reactor. In this paper the high density limit is studied in the reversed field experiment (RFX-mod) device in Padova, Italy. A rather complete experimental picture of the high density regimes is provided, showing a series of features, such as, plasma flow inversion in the edge, density accumulation, radiation condensation (poloidally symmetric and toroidal asymmetric) which resemble the MARFE phenomenon characteristic of tokamak discharges. However, in RFX-mod high density does not cause a disruption, as often observed in tokamaks, but a soft landing of the plasma current. According to a new 1D transport/radiative code applied to analyze the high density discharges, the current decay is due to an increased need for dynamo in these highly resistive, edge-cooled discharges. The relation between the radiative pattern of RFX-mod high density plasmas, the magnetic topology, and edge radial electric field is discussed.
Radiation directionality measurement of clarinets made of different wall material

The radiation-directivity patterns of clarinets are measured using an artificial blowing system which can ensure stable and reproducible tones. A reed is set in a box-shaped mouth and driven by the high-pressured air from an air compressor after adequately adjusting the embouchure formed by artificial lips made of silicone rubber. Our measurement in an anechoic chamber is carried out on three kinds of clarinets whose wall materials are grenadilla and ceramic by applying a common reed-mouthpiece setup. Lateral and circumferential directivity patterns are measured when all keys are untouched. A characteristic conical radiation is commonly indicated in lateral directivity patterns of three clarinets. Also, the effect of tone holes appreciably appears in circumferential directivity patterns measured near the clarinet center or in far field. However, that effect may be almost negligible in circumferential directivity measured near the barrel and bell. Proper improvements of the blowing system as well as careful applications of directivity measurement and near-field measurement will draw some correlations between the wall material and the radiated sound of the clarinet with tone holes closed.
Estimations of Total Ecosystem Biomass and Carbon Storage for Fir (Abies nordmanniana S. subsp. bornmülleriana (Mattf.)) Forests (Western Black Sea Region)

With increasing CO2 in the atmosphere, there is an urgent need of reliable estimates of biomass and carbon pools, especially in Turkey where there is a serious lack of data. Information on amount of carbon biomass resulting from direct field measurements is crucial in this context, to know how forest ecosystems will affect the carbon cycle and also to validate the measurements. Biomass data were collected over the different vegetation types and land uses of pure fir forests in the Western Black Sea region in Turkey. Using site-specific allometric equation, we estimated biomass and carbon pools. We used GIS technology to develop a carbon biomass map of our study area. We estimated aboveground carbon, root carbon, and soil organic carbon down to 30 cm depth. This study will provide estimates of biomass and carbon pools from pure fir forests in the Western Black Sea region as well as an appropriate methodology to estimate based on ecosystem carbon storage components.
Do delayed effects of overgrazing explain population cycles in voles

Theoretical models predict that delayed density-dependent processes with a time-lag of approximately nine months are sufficient to generate regular 3-5 year fluctuations in densities of northern small rodents. To examine whether this time-lag could be generated by plant-herbivore interactions, we studied delayed effects of overgrazed food plants on voles. We introduced field voles (Microtus agrestis) in four large predator-proof enclosures that had suffered heavy grazing during the preceding autumn and winter, and compared them with voles introduced to previously ungrazed control areas. We found no detrimental effects of previous grazing on population growth, reproduction or body condition of voles. Chemical analyses did not show consistent effects of grazing on nutritional components of common food plants (grasses). These results suggest that short-term population cycles of Microtus voles in grassland habitats are not primarily driven by delayed effects of plant-herbivore interactions.

Quantitative spatial magnetization distribution in iron oxide nanocubes and nanospheres by polarized small-angle neutron scattering

By means of polarized small-angle neutron scattering, we have resolved the long-standing challenge of determining the magnetization distribution in magnetic nanoparticles in absolute units. The reduced magnetization, localized in non-interacting nanoparticles, indicates strongly particle shape- dependent surface spin canting with a 0.3(1) and 0.5(1) nm thick surface shell of reduced magnetization found for ∼9 nm nanospheres and ∼8.5 nm nanocubes, respectively. Further, the reduced macroscopic magnetization in nanoparticles results not only from surface spin canting, but also from drastically reduced magnetization inside the uniformly magnetized core as compared to the bulk material. Our microscopic results explain the low macroscopic magnetization commonly found in nanoparticles.
Achievement, anxiety, self-concept and motivation among college algebra students within a cooperative learning structure

Cooperative learning methods have been shown to increase student achievement and social skills, therefore these methods have been promoted for the intervention of falling student achievement. This study was designed to examine the differences between a traditional lecture classroom structure and a cooperative learning structure in student achievement, anxiety, self-concept and motivation among College Algebra students. The sample is a convenience sample since participants were taken from pre-formed sections of College Algebra at a large urban university. This is a quantitative study, designed as a 2 × 2 factorial quasi-experiment. Using multivariate and univariate analysis of variance procedures, math achievement, anxiety, self-concept and motivation gains are examined. In addition, predictions about the target population‟s probability of passing the course for both treatment and comparison groups are estimated using a logistic regression analysis.
Three Dimensional Ceramics Printing to Create Ordered Dendrite Structures for Energy and Material Flows Modulation

Ceramics dendrite structures with geometrically ordered lattices had been created successfully by using a laser scanning and micro patterning stereolithography. Micro rods of alumina, zirconia, titania and hidroxiapatite were connected to realize coordination numbers of four, six, eight and twelve for fluctuation modulations of electromagnetic wave, electronic current propagation, heat diffusion, stress distribution, liquid flow and gas dispersion. Intensity profiles of these energy fields and material densities were visualized theoretically though finite element methods to compare with measured results. Technological concepts of these ceramics dendrites can be applied to novel censor devices, composite materials, solid electrodes and biological implants in the near future. In this paper, fabrication processes of ceramic dendrites and numerical simulations of spatial gas flows, electromagnetic wave propagations and biological fluid flows will be discussed for novel energy production devices and biocompatible implants.
Methane sources, distributions, and fluxes from cold vent sites at Hydrate Ridge, Cascadia Margin

To constrain the fluxes of methane (CH4) in the water column above the accretionary wedge along the Cascadia continental margin, we measured methane and its stable carbon isotope signature (δ13C‐CH4). The studies focused on Hydrate Ridge (HR), where venting occurs in the presence of gas‐hydrate‐bearing sediments. The vent CH4 has a light δ13C‐CH4 biogenic signature (−63 to −66‰ PDB) and forms thin zones of elevated methane concentrations several tens of meters above the ocean floor in the overlying water column. These concentrations, ranging up to 4400 nmol L−1, vary by 3 orders of magnitude over periods of only a few hours. The poleward undercurrent of the California Current system rapidly dilutes the vent methane and distributes it widely within the gas hydrate stability zone (GHSZ). Above 480 m water depth, the methane budget is dominated by isotopically heavier CH4 from the shelf and upper slope, where mixtures of various local biogenic and thermogenic methane sources were detected (−56 to −28‰ PDB). The distribution of dissolved methane in the working area can be represented by mixtures of methane from the two primary source regions with an isotopically heavy background component (−25 to −6‰ PDB). Methane oxidation rates of 0.09 to 4.1% per day are small in comparison to the timescales of advection. This highly variable physical regime precludes a simple characterization and tracing of “downcurrent” plumes. However, methane inventories and current measurements suggest a methane flux of approximately 3 × 104 mol h−1 for the working area (1230 km2), and this is dominated by the shallower sources. We estimate that the combined vent sites on HR produce 0.6 × 104 mol h−1, and this is primarily released in the gas phase rather than dissolved within fluid seeps. There is no evidence that significant amounts of this methane are released to the atmosphere locally.
Regional spatial planning assessments for adaptation to accelerated sea level rise - an application to Martinique’s coastal zone

Accelerated sea level rise and hurricanes are increasingly influencing human coastal activities. With respect to the projected continuation of accelerated sea level rise and global warming one must count with additional expenses for adaptation strategies along the coasts. On the mountainous island Martinique the majority of settlements are situated along the coast almost at sea level. But potential rises in sea level and its impacts are not addressed in coastal management, even if saltwater intrusion and coastal erosion with increasing offshore loss of sediment are locally already a severe problem. Following article deals with the evaluation of human vulnerability to accelerated sea level rise on the Martinique coast. In addition, it assesses the possible effects of sea level rise on the island for future regional planning purposes spatially. The actual situation and legislation measures for coastal zone management of the island are described and sea level rise response strategies are discussed. This paper sees itself as recommendation of action not only for Martinique.
Disturbance Rejection in Multi-Rotor Unmanned Aerial Vehicles Using a Novel Rotor Geometry

This paper presents a novel multi-rotor Unmanned Aerial Vehicle (UAV). The UAV, or OmniCopter, has eight rotors: four lift rotors in the typical quadcopter layout and four thrust motors that are orthogonal to the lift rotors and arranged as two pairs of coaxial counter-rotating rotors. The OmniCopter layout allows the decoupling of translation and orientation that is found in traditional multi-rotor UAVs. The OmniCpoter is able to translate in the plane orthogonal to the lift rotors without having to first roll and/or pitch. Testing is undertaken to determine the OmniCopters ability to reject disturbances from gusting winds. The results show that the OmniCopter has better disturbance rejection abilities when compared to the traditional multi-rotor layout.
The Relationship between Body Image and Physical Activity in African American Women

METHODS: Anthropometric measures of BMI and Pulvers’ culturally relevant body image[3], International Physical Activity Questionnaire (IPAQ)[4], socioeconomic status and uni-directional ActiGraph GT1M accelerometer [5] data were collected from 249 AA women in Houston. Raw silhouette data was converted to BMI, ranging from 16 to 40 kg/m2. Measured, perceived and desired BMI were used to create normal, overweight and obese weight status categories used in analyses. IPAQ physical activity type, work-related, transportation, domestic and leisure-time, and intensity, walking-, moderateand vigorous-intensity physical activity, were used in analyses. Accelerometer activity counts were converted to minutes and an individual-specific cutpoint was used to determine whether each minutes was spent doing moderate or greater physical activity. An average number of minutes spent doing moderate or greater physical activity was used in analyses.
Developmental Subjects and Developmental Institutions of the Russian Economy (Federal and Regional Levels)

The article was devoted to the problem of creation of «developmental institutions» multilevel system in the Russian economy. «Developmental institutions’» criteria and objects were defined. Also groups that were interested in their formation were pointed out. It was supposed that groups of interests could be divided into «developmental agents» and «developmental subjects». «Developmental agents» had got resources and instruments that were used to develop Russian economy whereas «developmental subjects» should also have had powerful bargaining positions and political will to produce selective incentives for «developmental agents». Special attention was paid to the «Federal Center – Regions» relations which predetermined peculiarities of creating «developmental institutions» system. Also it was crucial to take into account the power of bargaining positions of interested groups which interplayed on the political-bureaucratic market.
