Determination of Phenolic Compounds in Pinus eldarica by HPLC

Background: The antioxidant components have been identified in some pine species. Antioxidant properties of proantocyanidins reduce free radicals induced by DNA fragmentation and lipid proxidation and also proanthocyanidines could curb lipid peroxidation. Objective: In this study, we analyzed different parts of Pinus eldarica (bark, seed and needle) and assessed their antioxidant contents. Methods: Pine specimens were collected from four different geographic locations in Tehran. The HPLC method (UV detector, C18 reverse phase column, 4.6 mm (25 cm, and water/ H3PO4/ methanol/ acetonitril as eluant) were employed for evaluating total polyphenols. The wavelength for detection of polyphenolic compounds was 280 nm in this study. Results: The highest range of total polyphenols was detected in the bark of this pine, specially reported a considerable amount of tyrosol in Pinus eldarica. Tyrosol stimulated resistance to oxidative stress and also has anti aging effect. Conclusion: The high amount of total phenolic compounds in P. eldarica bark might be attractive for future research considering its health benefits.

Magnetocapacitance and dissipation factor of epitaxial graphene-based quantum Hall effect devices

We investigate the properties of the magnetocapacitance and dissipation factor of epitaxial graphene Hall bars with different electrode configurations to gain insight into the underlying physical mechanisms. The dependence of magnetocapacitance and dissipation factor on the magnetic field shows how the screening ability of the two-dimensional electron gas (2DEG) changes at the transition from the nonquantized to the quantized state. Both magnetocapacitance and dissipation factor exhibit a characteristic and correlated voltage dependence, which is attributed to the alternating contraction and expansion of the nonscreening 2DEG regions due to the alternating local electric field. Two regimes with seemingly different voltage dependencies are explained as the limiting cases of weak and strong electric fields of the same general voltage dependence. Electric fields in the plane of the 2DEG are found to cause about three orders of magnitude more ac dissipation than perpendicular electric fields. This strong directionality is attributed to the fact that the electrons are mobile in the plane of the 2DEG but are confined in the third dimension. In the quantized state, not only the screening edge of the 2DEG but also compressible puddles embedded in the bulk cause ac dissipation, as follows from the measured frequency dependence. Finally, characteristic parameters like the width of the screening edge, the threshold voltage, and the charging time of the compressible puddles are determined.
NBER WORKING PAPER SERIES THE MACROECONOMIC EFFECTS OF HOUSING WEALTH, HOUSING FINANCE, AND LIMITED RISK-SHARING IN GENERAL EQUILIBRIUM

This paper studies a quantitative general equilibriummodel of the housing market where a large number of overlapping generations of homeowners face both idiosyncratic and aggregate risks but have limited opportunities to insure against these risks due to incomplete financial markets and collateralized borrowing constraints. Interest rates in the model, like housing and equity returns, are determined endogenously from a market clearing condition. The model has two key elements not previously considered in existing quantitative macro studies of housing finance: aggregate business cycle risk, and a realistic wealth distribution driven in the model by bequest heterogeneity in preferences. These features of the model play a crucial role in the following results. First, a relaxation of financing constraints leads to a large boom in house prices. Second, the boom in house prices is entirely the result of a decline in the housing risk premium. Third, low interest rates cannot explain high home values.

A comprehensive characterization of the interfaces in Mo/CIS/CdS/ZnO solar cell structures

The alignment of energy bands in a Mo/CIS/CdS/ZnO solar cell structure is presented. Special attention is paid to the surface chemistry of the molybdenum coated substrate. In this study we have performed in situ analyses on polycrystalline thin films starting from the molybdenum coated soda lime glass. The different films have been deposited sequentially under ultra high vacuum conditions and analyzed with photoelectron spectroscopy techniques. We have found that Mo surface is significantly oxidized. Air annealing at 200/spl deg/C leads to a diffusion of sodium through the Mo layer. Mo-O and Mo-Se compounds are formed and present during the evolution of the Mo-CIS interface. Band lineups have been determined for the CIS/CdS/ZnO interfaces of the solar cell structure. We have found no indication for band discontinuities deteriorating the solar cell device performance.
Clinical, Cosmetic and Investigational Dermatology Juvéderm ® Volbella™ in the Perioral Area: a 12-month Prospective, Multicenter, Open-label Study

Background: Hyaluronic acid dermal fillers are frequently used for lip augmentation, and a new filler has been developed with characteristics especially suited for the lips. Methods: Four European sites treated 60 subjects with Juvéderm ® Volbella™ injectable gel in the perioral area, and subjects returned to the clinic at 1, 3, 6, 9, and 12 months for follow-up. The primary effectiveness endpoint established a priori was a Month 3 responder rate on the 4-point Lip Fullness Scale (LFS) of $40% and statistically. 0%, where responders improved $ 1 point from baseline on the investigator's assessment of LFS. At follow-up, subjects assessed lip fullness goal achievement, the look and feel of their lips, and their satisfaction with the effects of treatment. Results: The Month 3 LFS responder rate was 93.2% (P , 0.0001), so the primary endpoint was met, and clinical effectiveness was demonstrated. The responder rate over time showed that 78.0% of subjects still had improved lip fullness at Month 9 and 48.3% at Month 12. After treatment 98.3% of subjects reported that their lip fullness goal had been achieved, and this was maintained at 86.4% at Month 9 and 56.9% at Month 12. At Month 1, 81.0% of subjects reported that their lips felt smooth, and 91.4% reported that their lips looked natural (scores of 7–10 on an 11-point scale, where 0 was an unfavorable outcome and 10 was a favorable outcome). Similarly, 96.6% of subjects reported being satisfied (scores between 7 and 10 on an 11-point scale where 0 = very dissatisfied, 10 = very satisfied) at Month 1, and by Month 12 more than 80% of subjects were still satisfied. There were no severe adverse events related to treatment. Conclusion: Juvéderm ® Volbella™ injectable gel is well tolerated and has been demonstrated to provide a smooth and natural improvement in lip fullness that lasts for up to 1 year.
properties of p-valent functions

In this paper we ﬁrst deﬁne a new class of operators which is expressed as an iterated application (or composition) of two linear operators. Using simple identities and applying certain key lemmas, we focus ourselves to obtain certain subordination properties involving this introduced operator. Special cases of the results are also considered. The concluding section brieﬂy describes the lines of further extension of the main results and their relevances with various known results.
Explicit modeling of human-object interactions in realistic videos

We introduce an approach for learning human actions as interactions between persons and objects in realistic videos. Previous works typically represent actions with low-level features such as image gradients or optical flow. In contrast, we explicitly localize in space and track over time both the object and the person, and represent an action as the trajectory of the object wrt to the person position. Our approach relies on state-of-the-art approaches for human [28] and object detection [11] as well as tracking [3]. We show that this results in human and object tracks of sufficient quality to model and localize human-object interactions in realistic videos. Our human-object interaction features capture relative trajectory of the object wrt the human. Experimental results on the Coffee & Cigarettes [22] and the video dataset of [17] show that (i) our explicit human-object model is an informative cue for action recognition; (ii) it is complementary to traditional low-level descriptors such as 3D-HOG extracted over human tracks. When combining our humanobject interaction features with 3D-HOG features [20], we show to improve over their separate performance as well as over the state of the art. Key-words: Action Recognition, Human-Object Interaction, Video Analysis. ∗ A. Prest is with the Computer Vision Laboratory at ETH Zurich and with the LEAR team at INRIA Grenoble. † V.

Noise radiated by an open cavity at low Mach number: Effect of the cavity oscillation mode

The present work focuses on the study of noise generation and radiation of an infinite open three-dimensional cavity at low Mach number with laminar upstream conditions that is of interest to understand noise generation mechanisms in wall-bounded separated flows. A particular feature of this configuration is the oscillatory mode: shear layer mode or wake mode. For the parameters considered in the present study it is seen that while in shear layer mode the flow shows a two-dimensional behavior, in the wake mode the flow is three-dimensional, resulting in significantly different sound sources. The influence of the acoustic feedback mechanism in the shear layer mode has also been investigated comparing the results between different momentum thickness values at the cavity inlet. This paper presents results of sound radiated by a three-dimensional infinite open cavity with aspect ratio L/D = 4 at Reynolds number based on the cavity depth of ReD = 1500 and Mach number of M = 0.15, both for shear layer (L/θ = 67) and wake (L/θ = 84) oscillation modes. To do so, Curle integral evaluated as a post-process of an incompressible solution will be used. The results are compared with the resulting Curle post-process of a two-dimensional incompressible simulation.
RELATIONSHIPS BETWEEN VEGETATION COMPOSITION AND ENVIRONMENTAL VARIABLES IN THE BORANA RANGELANDS , SOUTHERN OROMIA , ETHIOPIA

Topography, climate and soil are the three important environmental abiotic factors that affect vegetation composition in rangelands. Determination of environmental factors that are responsible for the spatial distribution and abundance of vegetation is useful in ecological restorations and grazing land use planning. This study was conducted in the Borana lowlands to quantitatively explore relationships between vegetation composition and abiotic environmental factors. A combination of stratification and systematic random sampling techniques were employed to collect vegetation and environmental data in 58 plots of 500 m2 size. Redundancy Analysis (RDA) and Canonical Correspondence Analysis (CCA) were used to detect patterns of vegetation variation that were explained by the assessed environmental variables. CCA and RDA ordination diagrams revealed that the composition and distribution of both woody and herbaceous vegetation were mainly determined by altitude, soil pH, calcium, cation exchange capacity and magnesium. Density of woody plants was negatively correlated with altitude. Species richness was positively correlated with sand and altitude but negatively correlated with soil nutrients and clay content. It is concluded that the measured environmental variables significantly account for variation in the composition and distribution of the plant species composition in the Borana lowlands. Therefore, rangeland managers should incorporate environmental factors in planning and implementing restoration activities and planning grazing land use. Key words/phrases: Abiotic environmental factors, Borana rangelands, spatial distribution
HCV-specific cellular immune responses in subjects exposed to but uninfected by

Hepatitis C virus (HCV) is a major cause of chronic hepatitis, cirrhosis, and liver cancer occurring in up to 3% of the world’s population. Parenteral exposure to HCV is the major mode of transmission of infection. Once established, infection will persist in up to 85% of individuals with only a minority of patients clearing viremia. Egypt has possibly the highest HCV prevalence in the world where 10–20% of the general population are infected with HCV. Endemic HCV appears to be concentrated in the tropics and sub-tropics where there are higher biting rates from insects. The question as to whether a bridge vector transmission is possible, via arthropods, both between humans and/or from an animal reservoir to humans is explored. Mechanical transmission, as opposed to biological transmission, is considered. Mechanical transmission can be an efﬁcient way of transmitting an infection, as effective as biological transmission. Probability of transmission can increase as to the immediate circumstances and conditions at the time. Several factors may enhance mechanical transmission, including high levels of microbes in the vector, frequent biting, the close proximity, and contact between vectors and recipients as well as high density of insects. HCV has been isolated from bodies or heads of mosquitoes collected from the houses of HCV-infected individuals. The possibility of enzootic cycles of HCV tangential transmission via bridging vectors, such as, arthropods needs to be further investigated and possible animal reservoirs, including domestic rural epizootic cycles for HCV infection, requires further research with particular initial emphasis on equine infections.

Genetic influence on methadone treatment outcomes in patients undergoing methadone maintenance treatment for opioid addiction: a pilot study

Introduction: Treatment of opioid addiction with methadone is effective; however, it is known to produce interindividual variability. This may be influenced in part by genetic variants, which can increase the initial risk of developing opioid addiction as well as explain differ-ences in response to treatment. This pilot study aimed to assess the feasibility of conducting a full-scale genetic analysis to identify genes that predict methadone treatment outcomes in this population. Methods: This was a cross-sectional observational study of patients admitted to a methadone maintenance treatment program for opioid addiction. We obtained demographic and clinical characteristics in addition to blood and urine samples, for the assessment of treatment outcomes. Results: The recruitment process yielded 252 patients, representing a 20% recruitment rate. We conducted genetic testing based on a 99.6% rate of provision of DNA samples. The average retention in treatment was 3.4 years, and  50% of the participants reported psychiatric and medical comorbidities. BDNF rs6265 and DRD2 rs1799978 were the common single nucleotide polymorphisms (SNPs) selected for the feasibility study. Discussion: This study met our predetermined feasibility criteria; recruitment, response rates, and genetic testing were feasible; treatment duration was sufficient for follow up; and the prevalence of comorbid conditions indicated the need for reliable psychiatric and chronic pain measures. The study strengths included effective collaboration with clinics and the generaliz-ability of sample population. Key learning points show the need for assessment of treatment outcomes on multiple domains, implementation of follow up, and the development of standardized training for the study clinical

Joint Program on the Science and Policy of Global Change Probabilistic Forecast for 21 st Century Climate Based on Uncertainties in Emissions ( without Policy ) and Climate Parameters

The MIT Integrated Global System Model is used to make probabilistic projections of climate change from 1861 to 2100. Since the model’s first projections were published in 2003 substantial improvements have been made to the model and improved estimates of the probability distributions of uncertain input parameters have become available. The new projections are considerably warmer than the 2003 projections, e.g., the median surface warming in 2091 to 2100 is 5.1C compared to 2.4C in the earlier study. Many changes contribute to the stronger warming; among the more important ones are taking into account the cooling in the second half of the 20 century due to volcanic eruptions for input parameter estimation and a more sophisticated method for projecting GDP growth which eliminated many low emission scenarios. However, if recently published data, suggesting stronger 20th century ocean warming, are used to determine the input climate parameters, the median projected warning at the end of the 21 century is only 4.1C. Nevertheless all our simulations have a very small probability of warming less than 2.4C, the lower bound of the IPCC AR4 projected likely range for the A1FI scenario, which has forcing very similar to our median projection. The probability distribution for the surface warming produced by our analysis is more symmetric than the distribution assumed by the IPCC due to a different feedback between the climate and the carbon cycle, resulting from a different treatment of the carbon-nitrogen interaction in the terrestrial ecosystem.
Journal of Economic Behavior and Organization

This study uses data from a survey of micro, small, and medium enterprises in India to document the impact of Covid-19 containment lockdowns on ﬁrms, their responses, and adaptation strategies. We ﬁnd that the proﬁts and sales declined substantially for the ma- jority of ﬁrms. Temporary closures, pay cuts, and temporary lay-offs were the key measures utilized by ﬁrms to cope with the shock. Firms did not have adequate liquidity to last beyond six months, albeit the majority expected the pandemic to be over within that period. Micro-enterprises were the most fragile. Using a retrospective panel and matching- based difference-in-differences strategy, we show that exporting ﬁrms were able to cushion themselves from the domestic market contractions resulting from the lockdown.
Earth versus Neutrinos: Measuring the total muon-neutrino-to-nucleon cross section at ultra-high energies through differential Earth absorption of muon neutrinos from cosmic rays using the IceCube Detector

Author(s): Miarecki, Sandra C. | Advisor(s): Shapiro, Marjorie D. ; Klein, Spencer R. | Abstract: The IceCube Neutrino Detector at the South Pole was constructed to measure the flux of high-energy neutrinos and to try to identify their cosmic sources. In addition to these astrophysical neutrinos, IceCube also detects the neutrinos that result from cosmic ray interactions with the atmosphere. These atmospheric neutrinos can be used to measure the total muon neutrino-to-nucleon cross section by measuring neutrino absorption in the Earth. The measurement involves isolating a sample of 10,784 Earth-transiting muons detected by IceCube in its 79-string configuration. The cross-section is determined using a two-dimensional fit in measured muon energy and zenith angle and is presented as a multiple of the Standard Model expectation as calculated by Cooper-Sarkar, Mertsch, and Sarkar in 2011. A multiple of 1.0 would indicate agreement with the Standard Model. The results of this analysis find the multiple to be 1.30 (+0.21 -0.19 statistical) (+0.40 -0.44 systematic) for the neutrino energy range of 6.3 to 980 TeV, which is in agreement with the Standard Model expectation.
Developing Deep Understanding about Language in Undergraduate Pre-Service Teacher Programs through the Application of Knowledge.

The development of deep understanding of theoretical knowledge is an essential element of successful tertiary-programs that prepare individuals to enter professions. This study investigates the extent to which an emphasis on the application of knowledge within curriculum design, teaching strategies and assessment methods developed deep knowledge about language within the first year of a tertiary-based teacher education program in Australia. Concepts of application from literature on tertiary-based learning informed the design of curriculum, teaching strategies and assessment within a unit on linguistics for pre-service teachers. Questionnaires, provided to students at the end of the unit, and analysis of a final assessment task, provided insight into the extent to which the strategies designed to develop deep understanding were successful. The results indicate that an emphasis on the application of knowledge, within a discipline context, can support the development of understanding in units that do not have immediate links with professional practice.
Post-Crisis Capital Account Regulation in South Korea and South Africa

In the immediate aftermath of the global financial crisis, the world economy was characterized as experiencing a ‘two-speed’ recovery. Industrialized nations, where the crisis occurred, saw slow growth whereas many emerging market and developing countries grew significantly. These growth differentials, coupled with significant interest rate differentials across the globe, triggered significant flows of financial capital to the emerging market and developing countries. As a result, many countries experienced sharp appreciations of their currencies and associated concerns about the development of asset bubbles. This paper examines measures taken to mitigate the harmful effects of excessive capital flows in South Korea and South Africa. Each of these nations experienced similar surges in inflows with associated exchange rate and asset bubble woes, but each took quite different approaches in an attempt to mitigate those effects. South Korea devised a series of capital account regulations on the inflow of capital whereas South Africa liberalized their existing regulations on capital outflows. We econometrically analyze the effectiveness of these measures and find some limited evidence that both countries’ measures were successful in lessening the appreciation and volatility of their exchanges rates. These nations were less successful in stemming asset bubbles.
