Valores de colinesterasa plasmática y eritrocitaria con ácido 6-6‘-ditiodinicotínico (DTNA) como indicador

Se realizo un estudio descriptivo transversal empleando acido 6-6‘-ditiodinicotinico (DTNA) como indicador para calcular los valores de la actividad de colinesterasa plasmatica (AchP) y eritrocitaria (AchE) humana y estandarizarlos para ser utilizados como indicadores de riesgo laboral por exposicion a organofosforados y carbamatos en la poblacion de la zona cafetera de Colombia. Se eligio esta tecnica pues es una alternativa precisa, sencilla y economica: con pocos interferentes permite analizar AchP y AchE, no se tiene que corregir con hemoglobina; el DTNA es estable congelado o refrigerado y permite analizar muchas muestras en poco tiempo. Se evaluaron 819 muestras de agricultores. La AchE fue significativamente mayor en las personas menores de 45 anos y en personas no fumigadoras, la AchP fue mayor en los fumigadores; esto es un indicador de que la poblacion fumigadora se encuentra expuesta a organofosforados y carbamatos de forma prolongada. Se sugiere utilizar como valores maximos de referencia de la AchE y AchP 11378 U/L y 10354 U/L, respectivamente como indicadores de intervencion ocupacional.
The Second of Two Parts

OZART HAD NOW BROKEN irrevocably with the Archbishop and Salzburg, and was faced with the problem of establishing himself in Vienna . Three courses were open to him, none of which excluded the others : he could take pupils ; he could make himself a sort of free lance, giving subscription concerts and accepting commissions ; or he could maneuver for a court appointment . Actually he tried all three, but the one in which he proved most successful was the giving of subscription concerts . The notion of so doing may have been suggested to him by the success of his old friend John Christian Bach in establishing a subscription series in London . For many years the Bach-Abel concerts had been one of the most brilliant events of the London musical season, patronized by the wealthy and fashionable ; and the fertile John
Smoothed Analysis of the ICP Algorithm for Arbitrary Probability Distributions

The Iterative Closest Point (ICP) algorithm is a commonly used algorithm to align two point clouds. Worst-case analysis gives an exponential upper bound on the running time, but the algorithm is observed to work more eﬃciently in practice. To reconcile this gap, Arthur and Vassilvitskii perform a smoothed analysis of the ICP by perturbing the inputs according to a Gaussian distribution. Their polynomial smoothed complexity implies that the ICP algorithm should perform well in practice. This paper generalizes their ﬁndings, by proving a polynomial smoothed complexity for two more general perturbation models. In both models, the points are drawn according to arbitrary probability density functions upper bounded by a perturbation parameter. In the ﬁrst model, the functions’ support is bounded to the unit hypercube. In the second model, their support is unbounded, but the probability distribution has exponentially decreasing tails.

Catastrophic antiphospholipid syndrome presenting with aortic barrage: case report and review of the literature

Catastrophic antiphospholipid syndrome (CAPS) is a life-threatening condition characterized by multiple thromboembolic events occurring in a short period of time, frequently accompanied by significant systemic inflammation. Aortic involvement is rare in antiphospholipid syndrome and it had been never described in the context of its catastrophic variant. Here, we report an unusual case of aortic occlusion as a debut manifestation of CAPS and discuss its clinical features with an up-to-date review of the literature to identify risk factors and clues for clinical practice.
Cellular stress responses of long-lived and cancer-resistant naked mole-rats

Abstract Objectives Some organisms are long-lived and naturally resistant to cancer such as naked mole-rats (NMRs). Studies have shown that these animals can better tolerate stress due to mechanisms, such as upregulation of antioxidant pathways and improved proteostasis. In the present study, we aimed to analyze the tolerance against stress and the cellular mechanisms related to the stress response in NMR cells comparative to mouse cells. Materials and methods NMR and mouse fibroblasts were exposed to cellular stresses including H2O2 and/or NaNO3 and the viability of the cells were analyzed. In addition messanger RNA (mRNA) expression of antioxidant transcription factor Nuclear factor erythroid-derived 2-like 2 (Nrf2) and its target gene NAD(P)H quinone dehydrogenase 1 (NQO1) were determined by qRT-PCR and comprehensive analysis of stress-related gene expression was performed by RNA-Sequencing in fibroblasts and induced pluripotent stem cells (iPSC). Results Surprisingly, NMR fibroblasts were found to be more sensitive than mouse cells to H2O2 and NaNO3. Furthermore, it was shown that fibroblasts and iPSCs mainly aren’t identical in the expression pattern of cellular defense signaling and several factors are mainly downregulated in NMR iPSCs. Conclusions Collectively, the data gained from the present study help to improve the understanding of evolved mechanisms that contribute to stress resistance, aging and cancer.
N-Doped graphene as a metal-free catalyst for glucose oxidation to succinic acid

N-Containing graphenes obtained either by simultaneous amination and reduction of graphene oxide or by pyrolysis of chitosan under an inert atmosphere have been found to act as catalysts for the selective wet oxidation of glucose to succinic acid. Selectivity values over 60% at complete glucose conversion have been achieved by performing the reaction at 160 °C and 18 atm O2 pressure for 20 h. This activity has been attributed to graphenic-type N atoms on graphene. The active N-containing graphene catalysts were used four times without observing a decrease in conversion and selectivity of the process. A mechanism having tartaric and fumaric acids as key intermediates is proposed.
INDONESIAN PATRONAGE INTENTION TOWARD E-COMMERCE Faruqi

Patronage intention toward retail store has been interesting topic for practitioners and researchers, and many previous research has been conducted about the patronage intention toward retail store and the previous research commonly focus to single store. It is still rare to focus on online store and e-commerce as overall. The purpose of this research is to determine the Indonesian patronage intention toward e-commerce. This conceptual study is focusing on the grand theory of The theory of reasoned action (TRA) and Expectation-Confirmation Theory (ECT) framework. The rigorous literature analysis sugests some prepositions positied thst website design, security, privacy, information quality, payment method, e-service quality, product quality, product variety and delivery service contributed to e-commerce satisfaction respectively; and has a significant mediating role ecommerce patronage intention. Future empirical research should be done quantitatively to support the hypotheses.
Voting Advice Applications and Elections

We analyze how the introduction of the voting advice application (VAA) smartvote affects voter turnout, voting behavior and electoral outcomes. The Swiss context offers an ideal setting to identify the causal effects of online information with aggregate real world data because smartvote was introduced in different cantons at different points in time. In contrast to previous experimental studies, we find that smartvote did not affect turnout but that voters more actively select candidates instead of parties by splitting their ballot. Our findings suggest that no specific parties seem to benefit from the change in voting behavior and we find no effects on aggregate electoral outcomes. D700, D720.
Measuring Inequality of Access: Modeling Physical Remoteness in Nepal

Simple linear distances between origin and destination poorly describe travel in Nepal, where rugged terrain, underdeveloped transportation infrastructure, and diverse vegetation heavily influence favorable travel routes. In this context, expected travel times explain more about the remoteness of starting locations than geographic distance. Applied to service facilities, these time‐based measures of remoteness amount to measures of physical accessibility to services. However, traditional survey‐based measures of time suffer from problems of inaccurate reporting and standard survey error. Instead, this study built a geographic information system–based cost time model of travel that enables more accurate and generalizable assessment of accessibility. Having validated the generic model and compared it with other popular metrics, the study demonstrates its value by inputting a variety of services into it. This paper provides descriptive analyses of accessibility trends to these services at national, provincial, municipal, and geographic scales and suggests research possibilities unlocked by such a general purpose model. The paper concludes with thoughts for how the data and analysis, both freely available public goods, can enable additional research and better policy making.
Strategic Export Motives and Linking Emission Markets

We explore the possibility of achieving a cooperative outcome when governments act non-cooperatively in a strategic environmental policy model where emission permit markets are linked. We introduce a specific distribution scheme of the permit revenues between the exporting countries so as to sustain the cooperative outcome as a subgame perfect Nash equilibrium. Participation in the scheme is endogenized and we show that it constitutes a subgame perfect Nash equilibrium as long as the countries are not too asymmetric. Our results are robust once we allow for multiple pollutants, different modes of competition and market power in the permits market.
Inward Looking Policies, Finite Change and Employment - the Capital Reallocation Effect

It is well recognized that there emerged a trend of inward looking trade policies even before COVID pandemic crippled the world. These were reflected in both BREXIT and US-China trade conflict. As countries become inward oriented, usually local prices start rising. With this backdrop this paper explores how rising local prices are likely to affect employment in the short and long run when we accommodate for finite change in a general equilibrium structure whereby sectors not only contract but might close down altogether due to capital reallocation effect following a price incentive. Mechanisms behind employment increase are very much different between the short and the long run. We discuss such mechanisms and results in a variety of structures essentially highlighting the significance of the extensive margin, targeted protection and non-traded good.
CAMA Centre for Applied Macroeconomic Analysis Global Uncertainty CAMA Working Paper 21 / 2021 February 2021

We estimate a novel measure of global financial uncertainty (GFU) with a dynamic factor framework that jointly models global, regional, and country-specific factors. We quantify the impact of GFU shocks on global output with a VAR analysis that achieves setidentification via a combination of narrative, sign, ratio, and correlation restrictions. We find that the world output loss that materialized during the great recession would have been 13% lower in absence of GFU shocks. We also unveil the existence of a global finance uncertainty multiplier: the more global financial conditions deteriorate after GFU shocks, the larger the world output contraction is.
The Cost of Public Funding with Direct and Indirect Taxation - a Revisit

The paper shows that the marginal cost of public funds (MCF) does not depend on whether public revenue is collected by taxation of consumer goods or income from factors supplied by households on the market. Atkinson and Stern (1974) concluded in their seminal paper that “[. ] whether the Conventional Rule provides an under- or over-estimate depends on the choice of taxed good [. ]. ” This conclusion has created confusion in the literature on the MCF and has been the basis for recent literature arguing that the standard measure of the MCF has weaknesses and should be replaced by alternative measures (Jacobs, 2018; Håkonsen, 1998). We show that the conclusion of Atkinson and Stern (1974) on this issue is not valid and is based on an error in their analysis.
The Application of UAV-Based Hyperspectral Imaging to Estimate Crop Traits in Maize Inbred Lines

Crop traits such as aboveground biomass (AGB), total leaf area (TLA), leaf chlorophyll content (LCC), and thousand kernel weight (TWK) are important indices in maize breeding. How to extract multiple crop traits at the same time is helpful to improve the efficiency of breeding. Compared with digital and multispectral images, the advantages of high spatial and spectral resolution of hyperspectral images derived from unmanned aerial vehicle (UAV) are expected to accurately estimate the similar traits among breeding materials. This study is aimed at exploring the feasibility of estimating AGB, TLA, SPAD value, and TWK using UAV hyperspectral images and at determining the optimal models for facilitating the process of selecting advanced varieties. The successive projection algorithm (SPA) and competitive adaptive reweighted sampling (CARS) were used to screen sensitive bands for the maize traits. Partial least squares (PLS) and random forest (RF) algorithms were used to estimate the maize traits. The results can be summarized as follows: The sensitive bands for various traits were mainly concentrated in the near-red and red-edge regions. The sensitive bands screened by CARS were more abundant than those screened by SPA. For AGB, TLA, and SPAD value, the optimal combination was the CARS-PLS method. Regarding the TWK, the optimal combination was the CARS-RF method. Compared with the model built by RF, the model built by PLS was more stable. This study provides guiding significance and practical value for main trait estimation of maize inbred lines by UAV hyperspectral images at the plot level.
Synthesis of Polyol from Sponge Gourd (Luffa aegyptiaca) Seed Oil and Production of Polyurethane Foam

The use of modified plant oils as a renewable feedstock in the chemical industry has become more desirable as we move towards a carbon-free society. In particular, epoxidized fatty acid derivatives derived from vegetable sources may be utilized as stabilizers and plasticisers in polymer, as lubricant additives and as constituents of polyurethane foams. Luffa aegyptiaca oil is a potentially abundant and inexpensive raw material for such products. The synthesis of a polyol product from Luffa aegyptiaca involves two key reaction steps, namely: epoxidation followed by hydroxylation. This study considers the optimization of the reaction conditions for the second step where epoxidized Luffa aegyptiaca seed oil is converted into a polyol. The hydroxylation reaction was performed in a batch reactor using a mixture of alcohols (methanol and isopropanol) with sulphuric acid as a catalyst. The conversion reaction of epoxidized Luffa aegyptiaca seed oil to product polyol is reaction time and temperature dependent. Optimal condition (maximum polyol yield) was achieved with a reaction time of 3h at a temperature of 50°C. Keywords— Epoxidation; hydroxylation; Luffa aegyptiaca; oil reaction conversion; polyol;
Data Dive into Transportation Research Record

Antonio, Texas. SUBASISH DAS T ransportation is vital to people’s quality of life. Rapid growth in population, miles traveled, urbanization, and emerging technologies like connected and autonomous vehicles have had a substantial impact on modern living. The rising application of emerging technologies, the increasing number of peer-reviewed journals and conference proceedings, and the significant growth in interdisciplinary collaborations reflect the significance of the size and scope of transportation research. However, transportation challenges and problems have changed over time, and the transportation research scope has also become more diverse. Because of the consistent evolution of the advances in solutions and technologies, transportation research has experienced an upsurge of publications in recent decades. Predicting future salient issues in any field of science that will dominate research is always a challenge, but as transportation research becomes more complex and cross-cutting, this challenge is critical. Research on statistical models of co-occurrence of trending topics has led to the growth of different, useful topic models. This efficient machine-learning technique helps researchers find concealed trends inside unstructured larger textual contents. To understand the research trends in the realm of complex transportation science and engineering, an analysis of journal articles from the Transportation Research Record: Journal of the Transportation Research Board (TRR) may be beneficial. By applying text mining and two topic modeling techniques, this article presents an empirical analysis of 28,987 articles published in the TRR from 1977 to 2018 to identify the publication trends.
Dried Dates Fruit and its Biochemical and Nutrient Content: Uses as Diabetic Food

Date fruit is an important a source of different types of food products. Dates nutrient is adding with the food consumption as the healthiest alternative. It contains a lot of sugar that gives the body high levels of mobility and heat energy which can be easily broken down in the body. Dates are very rich in vitamins, fibre, fat, protein and minerals like sodium, potassium, calcium, magnesium and iron. However, for diabetic patient, it cannot be recommended for having dates without reducing its sugar content. The study was carried out to investigate the reduction method of dates fruit sugar and nutrient content like biochemical content, N, K + , Ca ++ and Na + . From the results it can be described that fruit weight and diameter were lower in the dried fruit (having hot water treatment and sun drying) than in fresh fruit. Fructose, glucose and inverted sugar content were found lower (decreasing trend) in the dried fruit (having hot water treatment and sun drying) than in fresh fruit at different months after the fruit harvested. In addition to that mineral contents like nitrogen, potassium, calcium and sodium were found lower in the dried fruit than in fresh fruit. Therefore, results conclude that hot water treatment and sun drying treated fruit had the lowest sugar (fructose, glucose and inverted sugar) and nutrient content which is suitable for diabetic patient diet.
Information Spillovers in Sovereign Debt Markets

We develop a theory of information spillovers in primary sovereign bond markets where governments raise funds from a common pool of competitive investors who may acquire information about default risk and later trade in secondary markets. Strategic complementarities in information acquisition lead to the co-existence of an informed regime with high yields and high volatility, and a Pareto-dominant uninformed regime with low yields and low volatility. Small shocks to default risk in a single country may trigger information acquisition, retrenchment of capital flows, and sharp yield increases within and across countries. Competitive secondary markets strengthen information acquisition incentives, raise primary market yields, and amplify spillovers.
Study of chemical profiles of volatile and non-volatile bioactive compounds of muscadine grapes (Vitis rotundifolia) during ripening stages and evaluation of their in vitro biological properties

Muscadine grape (Vitis rotundifolia) is a popular fruit in the Southeastern United States because of its unique aroma and strong antioxidant capacity. Volatile organic compounds (VOCs) of a locally cultivated muscadine cultivar “Cowart” were characterized by solid phase micro-extraction (SPME) coupled with gas chromatographymass spectrometry (GC-MS). Twenty eight VOCs, including fruity short-chain esters, alcohols, terpenes, and carbonyl compounds, were detected based on mass spectra and Kovats indices. There are three main stages during berry development, including stage I (green), stage II (pink), and stage III (black in full maturity), corresponding to the color changes from green to black. Based on principal component analysis (PCA) and hierarchical clustering, the grapes in stages I and II had relatively similar flavor patterns, which were different from that in stage III. Butyl-2-butenoate, hexyl acetate, propyl acetate, ethyl trans-2-butenoate, hexyl-2-butenoate, ethyl acetate, butyl acetate, 1-octanol, ethyl hexanoate, and β-citral were representative volatiles in stage III, nonanal, decanal, and β-citronellol were distinct in stage II, and myrcenol, β-ocimene, and l-limonene were biomarkers in stage I. Understanding VOCs at each stage can assist farmers in choosing the optimal time to harvest muscadine grapes.
Do Regulations Based on Credit Ratings Affect a Firm's Cost of Capital?

In February 2003, the SEC officially certified a fourth credit rating agency, Dominion Bond Rating Service ("DBRS"), for use in bond investment regulations. After DBRS certification, bond yields change in the direction implied by the firm's DBRS rating relative to its ratings from other certified rating agencies. A one notch better DBRS rating corresponds to a 39 basis point reduction in a firm's debt cost of capital. The impact on yields is driven by cases where the DBRS rating is better than other ratings and is larger among bonds rated near the investment-grade cutoff. These findings indicate that ratings-based regulations on bond investment affect a firm's cost of debt capital.
Diophantine Gaussian excursions and random walks

We investigate the asymptotic variance of Gaussian nodal excursions in the Euclidean space, focusing on the case where the spectral measure has incommensurable atoms. This study requires to establish fine recurrence properties in 0 for the associated irrational random walk on the torus. We show in particular that the recurrence magnitude depends strongly on the diophantine properties of the atoms, and the same goes for the variance asymptotics of nodal excursions. More specifically, if the spectral measures contains atoms which ratios are well approximable by rationals, the variance is likely to have large fluctuations as the observation window grows, whereas the variance is bounded by the (d -- 1)-dimensional measure of the window boundary if these ratio are badly approximable. We also show that, given any reasonable function, there are uncountably many sets of parameters for which the variance is asymptotically equivalent to this function.
