Does “Dry Hit” Vaping of Vitamin E Acetate Contribute to EVALI? Simulating Toxic Ketene Formation During E-Cigarette Use
Authors: Narimani Milad , da Silva Gabriel
Published: March 2020

Vitamin E acetate (VEA) is strongly linked to the outbreak of electronic-cigarette or vaping product use-associated lung injury (EVALI). It has been proposed that VEA decomposition to ketene – a respiratory poison that damages lungs at low ppm levels – may play a role in EVALI. However, there is no information available on the temperature at which VEA decomposes and how this correlates with the vaping process. We have studied the temperature-dependent kinetics of VEA decomposition using quantum chemical and statistical mechanical techniques, developing a chemical kinetic model of the vaping process. This model predicts that, under typical vaping conditions, the use of VEA contaminated e-cigarette products is unlikely to produce ketene at harmful levels. However, at the high temperatures encountered at low e-cigarette product levels, which produce “dry hits”, ketene concentrations are predicted to reach acutely toxic levels in the lungs (as high as 30 ppm). We therefore hypothesize that dry hit vaping of e-cigarette products containing VEA contributes to EVALI.
A Hidden Assumption of Gouy-Chapman-Stern Model Fails Under Dynamic Conditions
Authors: Li Chenkun , Huang Jun
Published: March 2020

Understanding the double layer at the electrode-electrolyte interface is of fundamental importance to electrochemistry, and also lays the basis for rational design of energy storage and conversion technologies. The prevailing Gouy-Chapman-Stern (GCS) model and its many derivatives invariably picture the double layer as a serial connection of a compact layer and a diffuse layer. We unravel that these models based on the serial connection tacitly prescribe a zero potential gradient at the solution-side boundary. This assumption is generally invalidated under dynamical conditions, resulting in an incorrect expression for the double-layer impedance. Amendment of this deficiency gives out a revised analytical expression for the double-layer impedance at the potential of zero charge with new features. Specifically, the contribution of the compact layer now shows frequency dispersion. The deviation between the original and amended models is greater when the double layer is confined in narrower space. This work changes our basic understanding of double layer model and its impedance response.
The Pyruvate Aldol Condensation Product: A Metabolite that Escaped Synthetic Preparation for Over a Century
Authors: Rios Andro , Bera Partha , Moreno Jennifer , Cooper George
Published: March 2020

The homo-aldol condensation product of pyruvate, 2-methyl-4-oxopent-2-enedioic acid (OMPD) has been recently implicated as a catabolic intermediate in the bacterial degradation of lignin and previously identified from other biological sources in reports ranging over sixty years. Yet, while a preparation of the pyruvate aldol-product precursor, 4-hydroxy-4-methyl-2-oxoglutaric acid (HMOG) was first reported in 1901, there has not been a complete published synthesis of OMPD. Analysis of reaction mixtures have helped identify that it is zymonic acid, the lactone of HMOG, that is the direct precursor to OMPD. The reaction appears to proceed through an acid or base mediated ring opening that does not involve formal lactone hydrolysis. In addition to a preparative protocol we provide a proposed mechanism for the formation of methylsuccinic acid that arises from the non-oxidative decarboxylation of OMPD. Lastly, we report on the relative stability of the possible isomers of the condensation product and find that at all pH values, Z-OMPD is the most abundant.

Published: March 2020

This paper reports on performance of ceramic ultrafiltration and nanofiltration membrane to remove carbon ink particles, blue ink dye, Fe3+ and Cu2+ ions from water. The ceramic filters have α-Al2O3 flat-sheet supporter, with TiO2 nanoparticles sintered membrane on the surface of supporter. Carbon ink particles, blue ink dye, FeCl3 and CuSO4 water solution were used to test their filtration performance. The results show that the ceramic ultrafilter can 100% decolored the black carbon solution. The nanomembrane can 100% decolored blue ink dye, FeCl3 and CuSO4 solution. Electrical conductivity rate of ironflocculated dye waste water from a textile company can be reduced by the nanomembrane from 4000 μs/cm to 1000 μs/cm. It assumed that the ultramembrane pore size is about 10 nm, and the nanomembrane pore size might be 1 nm. The performance can fulfill the requirements for removal of heavy metal ions, materials with molecule bigger than 250 Dalton and salts retention from water, air filtration of novel corona virus defending mask and negative pressure patient room.
Metal–Ligand Exchange Coupling Promotes Iron-Catalyzed Electrochemical CO2 Reduction at Low Overpotentials

Published: March 2020

Biological and heterogenous catalysts for electrochemical CO2 reduction often exhibit a high degree of electronic delocalization that serves to minimize overpotential and maximize selectivity over hydrogen evolution. Here, we report a molecular iron(II) complex that achieves a similar feat as a result of strong metal–ligand exchange coupling. This interaction promotes an open-shell singlet electronic structure that drives the electrochemical reduction of CO2 to CO with over 90% selectivity and turnover frequencies of 100,000 s−1 at low overpotentials, with no degradation over 20 hours. The decrease in the thermodynamic barrier engendered by this strong metal–ligand exchange coupling enables homogeneous CO2 reduction catalysis in water without compromising reaction selectivity.

Consciência Situacional (SAW) refere-se ao nível de consciência que um indivíduo ou equipe detém sobre uma situação. No domínio criminal, falhas da SAW podem induzir operadores humanos a cometer erros na tomada de decisão e gerar riscos iminentes à vida e patrimônio. Além disso, domínios críticos com situações dinâmicas são propensos a problemas de qualidade da informação, especialmente quando a fonte dos dados são seres humanos. Considerando a natureza das informações e o contexto que estão envolvidos, as informações podem ser incompletas, ultrapassadas, inconsistentes ou influenciadas por fatores culturais e de estresse. Desta maneira, o objetivo deste trabalho é discutir o papel da qualidade de dados como parte relevante em um modelo de transformação de informação e como esta pode se relacionar com processos de inferência e representação. Resultados parciais indicam a real necessidade da aderência e avaliação contínua da qualidade dos dados para auxiliar a SAW e projeções situacionais. Espera-se que também, que o modelo possa dar suporte ao processamento de informações e análise de qualidade, resultando em informações com menor dimensionalidade, índices de melhor qualidade e mais representativos para auxiliar o ser humano.

Authors: Tiganescu Alexandru , Grecu Bogdan , Craifaleanu Iolanda Gabriela
Published: March 2020

The paper presents results from an experimental program implemented for three representative buildings in Bucharest metropolitan area and aimed to explore the potential of various dynamic identification methods in providing information about building state changes. The objective is to establish reference values of potential use in rapid earthquake damage detection systems. Each of the selected buildings was designed according to a different seismic code, in force at the time of its construction. The methods employed for this study were: the analysis of Fourier spectra, the analysis of the transfer function and the random decrement technique. To validate the results, the fundamental periods of vibration determined experimentally were compared with the corresponding values predicted by the empirical formulas specified in the corresponding editions of the Romanian seismic code. The results revealed consistent values for both the fundamental period and the damping ratio of the buildings. However, small variations of the two parameters were identified, depending on the time the recordings were performed, noise sources and levels and building occupancy. The results, in terms of validated data on the dynamic characteristics of Romanian building stock and of assessment of methods performance, add up to the information pool needed for the development of countrywide pre- and post-earthquake assisted decision tools.

Semi-quantitative ultrasound assessment of nonalcoholic fatty liver disease highlightens early subclinical atherosclerotic vascular damage: From risk factors to vascular damage
Authors: Cioni Gabriele , Marcucci Rossella , Abbate Rosanna , Boddi Maria
Published: March 2020

Introduction
Nonalcoholic fatty liver disease (NAFLD) is an independent risk factor for coronary artery disease; moreover, it increases systemic atherosclerotic burden by inducing the overexpression of inflammatory mediators, promoting endothelial damage, and impairing blood pressure regulation.
Aim
Aim of this work was to evaluate whether a standardized evaluation of NAFLD improves cardiovascular risk assessment recognizing subclinical atherosclerosis in lower cardiovascular risk.
Material and methods
We investigated NAFLD occurrence and severity, carotid and femoral intima-media-thickness (IMT) and vascular stiffness by ultrasound technique, endothelial function by peripheral-arterial-tonometry, lipid profile and inflammatory markers in 220 subjects (100 men, 120 women; 45.42 ± 13.22 years old), without history of cardiovascular event, diabetes, liver infection, alcohol consumption, systemic diseases, and the use of drugs causing liver damage. NAFLD was evaluated, graded according to an eight-point scoring semi-quantitative severity score.
Results and discussion
At univariate logistic analysis, NAFLD ≥ 3 score was significantly associated with pathological IMT, augmentation index, pulsewave-velocity at carotids and femoral arteries, and endothelial dysfunction, and this association was confirmed after adjustment for European Society of Cardiology Systematic Coronary Risk Evaluation (ESC SCORE) at multivariate analyses. Moreover, high sensitivity C-reactive protein levels were significantly higher in patients with at least 3 point steatosis, in comparison to the others. Receiver operating characteristic (ROC) curve analysis for NAFLD showed a significant higher area under curve for the detection of both early atherosclerotic burden and vascular stiffness, in comparison to ROC curve of ESC SCORE.
Conclusions
According to our findings a NAFLD ≥ 3 score was able to screen a subgroup with widespread morphological vascular damage and endothelial dysfunction in a primary prevention population.
Prediction of the Corrosion Inhibition Efficiency of Imidazole Derivatives: A Quantum Chemical Study
Authors: Hadisaputra Saprizal , Iskandar Zohrul , Asnawati Dina
Published: February 2020

Corrosion is a process of metal destruction due to the metal-acidic environment reaction. The uncontrolled corrosion process lead to massive losses. Administering inhibitors of organic compounds on the metal surface may prevent the corrosion processes. Organic inhibitors are low toxicity, environmentally friendly, effective easy to obtain and cheap. The study aims to determine the effect of substituents to the efficiency of corrosion inhibition of imidazole in carbon steel based on quantum chemical parameters. Corrosion inhibition efficiency values â€‹â€‹are strongly influenced by the addition of substituents namely electron donors (CH3, CHCH2, NH2, CH2OH and OH) and electron withdrawal (CHO, COOH, NO2, F and Cl). The addition of amine group NH2 increased the corrosion inhibition efficiency to 91 % whereas amino group NO2 reduced the efficiency of corrosion inhibition to 64 %. Analysis of the Fukui function shows that imidazole has active sides on the C1 and C3 atoms. NBO analysis shows that there is an interaction of N5 atoms that donate electrons to Fe13 at 8.67 kcal.mol-1. In conclusion, the addition of an electron donor group increases the efficiency of corrosion inhibition of imidazole.

The  compounds,  [UO2(dibenzo-18-crown-6)]2+  and  [UO2(18-crown-6)]2+,  as  well  as  their related complexes: numerous disubstituted dibenzo-18-crown-6 and azacrown complexes are studied  using  density  functional  theory  (DFT).  Quasi-relativistic  effective  core  potentials developed in the Stuttgart and Dresden groups was used together with the accompanying basis set for  uranium  and  DZP  basis  set  was used  for crown ether  atoms.  The  effects  of  substituent  and nitrogen number  on the binding selectivity were  discussed  in  term  of  the  structural  parameter,  atomic  charge  and interaction energy, thermodynamic parameters, and charge transfer. The electron donating substituents increase the capability of dibenzo-18-crown-6 toward UO22+ ion. In contrast, the electron withdrawing substituents have the opposite effect. It clearly shows that UO22+ prefers N donor recognition. For the systems involved, the result shows that the hexaaza-18-crown-6 exhibits the largest metal interaction capability to UO22+ ion. The calculated results are in a good agreement with the experimental values.

Purpose

There is a need for new tools to screen large populations for cardiovascular disease risk. The CARDIS consortium (European Union H2020 funding) developed an easy-to-use, non-contact device for measuring carotid to femoral pulse wave velocity (cfPWV). It consists in a laser doppler vibrometer (LDV), which measures skin vibrations induced by large artery pulses. Pulse waveforms can be tracked and transit time (TT) can be calculated. This study aimed at comparing LDV-cfPWV with the reference cfPWV measured by applanation tonometry (Sphygmocor).

Methods

We included 100 patients with mild to stage 3 hypertension, controlled or not. Reflective tapes were applied on the carotid and femoral arteries to measure LDV-cfPWV 4 times. TT was measured by the foot-to-foot method from the maximum of 2nd derivative using in-house algorithms not requiring ECG, and compared to Sphygmocor (3 acquisitions).

Results

LDV-cfPWV was obtained in 100% of patients. Mean age was 47 ± 19 (range 19–85). Hypertensives were well controlled (119/65 mmHg). Mean value of LDV-cfPWV was 6.9 ± 1.7 m/s, compared to 7.5 ± 1.7 m/s with Sphygmocor, bias 0.65 ± 1.27, R value 0.72 (Figure 1), which qualifies agreement as acceptable according to the guidelines from the ARTERY Society [1]. Reproducibility was good with a median coefficient of variation of 5.6%. LDV-cfPWV showed similar associations with age and blood pressure than tonometry (r = 0.68, p < 0.001 and r = 0.44, p < 0.001, respectively).

Conclusion

Non-contact measurement of pulse wave velocity by laser doppler vibrometry is feasible, fast and easy to perform, and provides acceptable agreement with reference technique.

From 2010 a new, complex screening program started in Hungary, it works with the support of 76 professional-scientific societies and companies. Within the framework of the Program in the largest mobile diagnostics center in Hungary 37 comprehensive surveys in free form. This enormous special screening station allows 5,100 tests to be performed at each of the 200 screening stations nationwide. The screening program for over 20 years provides 15 million trials on 3,000 scenes and 1 million adult visitors in free humanitarian form. The special screening lorry visited 1696 places, 206,529 inhabitants had a complex screen and 500,395 individuals received information packages about the right lifestyle, the prevention of illnesses and preservation of health and we have received 14 million lifestyle question answers on sites. Based on data from 2018, the age of participants was 42 years for women and 40 years in men. 22% in women, 23% in men was the rate of known hypertension and 5.1% and 4.5% was the proportion of known diabetics irrespectively. Similarly, the frequency of the known heart and kidney disease was low, but asthma allergy and eye disease were present in more than 20%. Myocardial infarction 26–22%, hypertension disease 62–55%, stroke 19–14%, cancer 47–38% and metabolic disease 42–34% occurred in the family history. BMI was increased in both genders, 45% in women and 59% in men. In both sexes, the proportion of smokers was over 24%. Based on the results, it has been repeatedly found that the Hungarian population has high risk.
