Abstract:
The synthesis of a series of 2,2′-bis(trimethyltetrel) azobenzenes is reported, evaluating the different synthetic approaches that different group 14 element substituents individually require. The synthetic access to the carbon substituted congener is very different from the heavier tetrels, in that the key step is the formation of the N=N bond in azobenzene, rather than the azobenzene-C bond. Sn could be introduced with a cross-coupling route, whereas the Si and Ge congeners were prepared by a stannylation-lithiation-electrophilic quenching sequence. Iodo-lithium exchange was also a possible route to obtain the dilithiated species, which can be attributed to the chelating effect of the nitrogen atoms. However, the organo-lead species could not be obtained via these routes. The resulting structures were fully characterized (NMR, FTIR, HRMS and XRD). Furthermore, their thermal properties (TGA and DSC) and their photoswitching behavior in solution (UV-VIS & NMR experiments) were investigated and compared for the different tetrels (C, Si, Ge, Sn).

Abstract:
Benzo( a)pyrene [B(a)P] is one of the most widely studied polyaromatic hydrocarbons. In the human body and in lower animals, B(a)P can become chemically bonded to DNA. Tetrols are the products obtained from the hydrolysis of B(a)P-DNA adducts. It has been proposed that the amount of tetrols detected in human body fluids can be used as a measure of the amount of B(a)P-DNA adducts present in the body. The effects of several heavy-atom salts on the solid-matrix fluorescence and phosphorescence properties of the tetrols were investigated. TINO3 and TIF were very useful in enhancing the room-temperature phosphorescence (RTP) of the tetrols. For tetrol I-1 on 1:1:8 α-cyclodextrin:TlNO3: NaNO3, the limit of detection was 0.38 femtomole/mg. The RTP approach with the 1:1:8 α-cycIodextrin:TlNO3:NaNO3 matrix would be useful for detecting subfemtomole quantities of the tetrols of B(a)P-DNA adducts from biological samples.

Abstract:
A unique laser-based method was developed for the solid-matrix fluorescence characterization and identification of tetrols, which are the hydrolysis products from benzo[ a]pyrene-DNA adducts. By employing different gatewidths with a boxcar integrator, we obtained the fluorescence spectra of the four tetrol isomers adsorbed on 10% α-cyclodextrin/NaCl at several temperatures. The data showed that the fluorescence spectral characteristics of the tetrols were both gatewidth- and temperature-dependent. The experimental conditions were optimized to identify the tetrols which had only minor structural differences. Applications of the gatewidth-dependence method both at room temperature and low temperature were considered. The low-temperature approach has the potential for the application to several species over a range of fluorescence lifetimes. The differences in the fluorescence spectral properties were partially explained by the rotation of functional groups in the tetrols and the solid matrix during the time frame of obtaining the spectra. Comparisons were made among the solid-matrix fluorescence spectra and the solution fluorescence spectra of the tetrols, and the solution fluorescence spectra of pyrene and the solid-matrix fluorescence spectra of pyrene.

Abstract:
Several solution fluorescence parameters were acquired for the four tetrol hydrolysis products of benzo[ a]pyrene-trans-7,8-dihydrodiol-9,10-epoxide (BPDE)-DNA adducts, tetrols complexed with DNA, and BPDE-DNA adducts in several methanol/water solvents. The relative polarity of the environment for the tetrols and BPDE-DNA adducts was determined by using a modified definition of the R value that is commonly employed for pyrene. The R values for the tetrols and BPDE-DNA adducts were calculated by obtaining the ratios of the intensities of the two major fluorescence emission bands at 380 and 400 nm ( I380/ I400). The positions of the hydroxyl groups on the hydroaromatic ring of the tetrols were compared in reference to the R values and the changes in the R values as a function of methanol/water composition. This approach resulted in a method for determining whether the hydroxyl groups in the 9 and 10 positions were on the same side or opposite sides of a hydroaromatic ring. The tetrols intercalated between the DNA bases showed quite different fluorescence spectra compared to tetrols not complexed with DNA. Also, the quasi-intercalated BPDE-DNA adducts gave significant changes in the R values with an increase in methanol in the solvent, and excitation spectra showed large shifts and changes in shape with an increase in methanol. The approaches developed provide unique structural and polarity information on tetrols and BPDE-DNA adducts.

Abstract:
Nine samples of human lymphocytes from six healthy subjects were treated in vitro for 24 hours with [3H]-benzo[a]pyrene (BaP) and unlabelled (-)-BaP-7,8-dihydrodiol; 1μg/ml and 0.5μg/ml, respectively. The separation by HPLC of BaP-DNA adducts showed a significant formation of syn-BaPDE-dGuo adducts in five out of the nine human lymphocyte samples treated in vitro with [3H]-BaP. BaP-(7,10/8,9) tetrol and BaP-(7/8,9,10) tetrol derived from (+)-anti-BaPDE were the predominant isomers extracted from the culture medium of all the lymphocyte samples treated with (-)-BaP-7,8-dihydrodiol (mean ratio of anti-BaPDE/syn-BaPDE tetrols 5.6 + 1.2), suggesting that the metabolic activation of (-)-BaP-7,8-dihydrodiol occurred by its epoxidation to (+)-anti-BaPDE much more frequently (4–8 times) than by epoxidation to the (-)-syn-BaPDE form. In contrast to the predominant formation of anti-BaPDE tetrols, the analysis by HPLC of DNA adducts in the five subjects examined also revealed the significant formation of syn-BaPDE-DNA adducts (mean adduct ratio of (+)-anti-/(-)-syn-BaPDE-DNA = 2.6 ± 0.7). In six human lymphocyte samples treated in vitro with anti-BaPDE and syn-BaPDE, the anti-BaPDE bound to DNA 2–5 times more efficiently than did the syn-BaPDE. However, after 24 hours, the level of anti-BaPDE-DNA adducts significantly decreased almost to the level of the syn-BaPDE-DNA adducts, suggesting that a stereoselective repair mechanism could have preferentially removed the anti-BaPDE-DNA adducts.

Abstract:
The paper presents the results of studying the nickel electroplating process in the presence of nanodiamond additives. It shows that the use of detonation nanodiamonds (DND) and diamond explosive charge (DC) obtained by explosion of tetryl (N-methyl-2,4,6-trinitrophenylnitramine) can significantly improve the physicochemical properties of nickel platings: increase the microhardness up to 60 % (up to 448 kgf/mm2 – 4393 MPa), obtain a non-porous nickel plaiting and reduce wear up to 28 times. The most effective was the use of non-expensive nanodiamonds, but cheap diamond charge obtained by the explosion of tetrile.

New steroidal saponins were found to be pentahydroxy 5-O-glycosides; 5β-spirost-25(27)-en-1β,2β,3β,4β,5β-pentol 5-O-β-galactopyranoside 9, 5β-spirost-25(27)-en-1β,2β,3β,4β,5β-pentol 5-O-β-arabinonoside 11, 5β-(25S)-spirostan-1β,2β,3β,4β,5β-pentol 5-O-galactoside 10 and 5β-(25S)-spirostan-1β,2β,3β,4β,5β-pentol 5-O-arabinoside 12 were isolated for the first time. The structures of those compounds were determined by NMR spectroscopy, including 2D COSY, HMBC, HSQC, NOESY, ROESY experiments, theoretical calculations of shielding constants by GIAO DFT, and mass spectrometry (FAB/LSI HR MS). An attempt was made to test biological activity, particularly as potential chemotherapeutic agents, using in silico methods. A set of 12 compounds was docked to the PDB structures of HER2 receptor and tubulin. The results indicated that diols have a higher affinity to the analyzed targets than tetrols and pentols. Two compounds (25S)-spirosten-1β,3β-diol 1 and 5β-spirost-25(27)-en-1β,2β,3β,4β,5β-pentol 5-O-galactoside 9 were selected for further evaluation of biological activity.

Abstract:
E-cigarette aerosol contains lower levels of most known carcinogens than tobacco smoke, but many users of e-cigarettes are also smokers, and these individuals may be vulnerable to possible promoting and/or cocarcinogenic effects of e-cigarettes. We investigated the possibility that a condensate of e-cigarette aerosol (EAC) enhances the metabolism of the tobacco carcinogen, benzo(a)pyrene (BaP), to genotoxic products in a human oral keratinocyte cell line. Cells were pretreated with EAC from two popular e-cigs and then with BaP. Metabolism to its ultimate carcinogenic metabolite, anti-7,8-dihydroxy-9,10-epoxy-7,8,9,10-tetrahydro B[a]P (BPDE), was assayed by measuring isomers of its spontaneous hydrolysis products, BaP tetrols. The pretreatment of cells with EAC enhanced the rate of BaP tetrol formation several fold. Pretreatment with the e-liquid resulted in a smaller enhancement. The treatment of cells with EAC induced CYP1A1/1B1 mRNA and protein. The enhancement of BaP tetrol formation was inhibited by the aryl hydrocarbon receptor (AhR) inhibitor, α-napthoflavone, indicating EAC likely induces CYP1A1/1B1 and enhances BaP metabolism by activating the AhR. To our knowledge, this is first report demonstrating that e-cigarettes can potentiate the genotoxic effects of a tobacco smoke carcinogen.

Abstract:
The idea behind this project was to implement and study biofeedback features in the popular video game Tetris, using EDA (Electrodermal activity). The goal was to explore if it is possible to deliberately alter live EDA measurements using a Q-Sensor wristband along with the game. Our implementation can change the speed of the game according to the current EDA value of the player. The problem was studied by issuing a user test experiment along with a survey questioning how test subjects responded to the biofeedback features. Results seemed to show that manipulating EDA in our version of Tetris seems possible, although subjects could only alter EDA for shorter periods of time rather than manipulating a general value. More accurate results would require more work and knowledge than presented in this study.
Tanken bakom detta projekt var att implementera och studera biofeedbackelement i det populära datorspelet Tetris genom att använda EDA (Electrodermal activity). Målet var att undersöka om det är möjligt att medvetet manipulera EDA-mätningar vid användandet av ett QSensor- armband tillsammans med spelet. Vår implementation kan ändra spelets hastighet beroende på vilket EDA-värde en spelare vid tillfället har. Problemet studerades genom att utföra ett användartest tillsammans med en fråge-enkät för att undersöka hur testpersoner svarade till biofeedback-elementen. Resultaten verkade visa att det kan vara möjligt att medvetet manipulera EDA-mätningar vid spelande av Tetris, dock kunde försökspersonerna bara förändra dessa mätningar under kortare perioder snarare än att påverka genomsnittsvärdet. Mer tillförlitliga resultat kräver betydligt mer arbete och kunskap än vad som framställs i denna rapport.

Abstract:
In a biofeedback system, data about the user’s physiological functions is measured and used as input for the system. EDA is a measurement of a persons stress and it is used in biofeedback systems. This essay is about measuring EDA with the Affectiva Q Sensor in the game Tetris. The relationship between EDA and the difficulty in the game has been analyzed, both through correlation analysis and curve fitting. In the game the difficulty can be controlled by implicit and explicit biofeedback, and this functionality has been used to see if users could learn to control their stress through explicit biofeedback. The result of the study was that there exists a corrrelation (the average correlation coefficient was 0.472) between EDA and difficulty. It was also shown that the players could not control their EDA with the help of explicit biofeedback
I biofeedback-system mäts och registreras data om användarens fysiologiska funktioner, för sedan kunna användas som indata till systemet. EDA är ett mått på hur stressad en person är och används i biofeedback-system. Denna uppsats handlar om att mäta EDA med hjälp av Affectiva Q Sensor i spelet Tetris. Sambandet mellan EDA och svårighetsgraden i spelet har undersökts, både med hjälp korrelationsanalys och kurvanpassning. I spelet kan svårighetsgraden styras med implicit och explicit biofeedback, och med denna funktionalitet har det testats det om det är möjligt för en spelare att kontrollera sin EDA med hjälp av den explicita feedbacken. Resultatet var att det finns en korrelation (medelvärdet för korrelationskoefficienten var 0.472) mellan EDA och svårighetsgrad, däremot kunde spelarna inte lära sig att kontrollera sin EDA (stress) när de spelade Tetris.

Abstract:
This paper studies the performance of height-based weighing functions and compares the results to using the commonly used non height-based weighing functions for holes. For every test performed, the heuristic methods studied in this paper performed better than the commonly used heuristic function. This study also analyses the effect of adding levels of prediction to the heuristic algorithm, which increases the average number of cleared lines by a factor of 85 in total. Utilising these methods can provide increased performance for a Tetris AI. The polynomic weighing functions discussed in this paper provide a performance increase without increasing the needed computation, increasing the number of cleared lines by a factor of 3. The breadth-first search provide a bigger performance increase, but every new level of prediction requires 162 times more computation. Every level increases the number of cleared lines by a factor of 9 from what has been observed in this study.

Abstract:
En base a los datos de la encuesta de la alianza INTAL-Latinobarómetro del año 2018, este estudio se propone analizar las diferentes opiniones entre mujeres y hombres acerca de la integración en América Latina y el Caribe. Busca confirmar la existencia de la brecha de género en la región, cuantificar su magnitud y explorar distintas hipótesis que puedan contribuir a comprender los determinantes de la brecha. Para ello, se realizan diferentes modelos de regresión lineal que captan las principales hipótesis estudiadas en la literatura sobre el tema y se trata de verificar en qué medida estas se cumplen en la región.

Crouch, Rebecca, Jared Smith, Bobbi Stromer, Christian Hubley, Samuel Beal, Guilherme Lotufo, Afrachanna Butler, et al. Methods for simultaneous determination of legacy and insensitive munition (IM) constituents in aqueous, soil/sediment, and tissue matrices. Engineer Research and Development Center (U.S.), August 2021. http://dx.doi.org/10.21079/11681/41720.

Abstract:
Currently, no standard method exists for analyzing insensitive munition (IM) compounds in environmental matrices, with or without concurrent legacy munition compounds, resulting in potentially inaccurate determinations. The primary objective of this work was to develop new methods of extraction, pre-concentration, and analytical separation/quantitation of 17 legacy munition compounds along with several additional IM compounds, IM breakdown products, and other munition compounds that are not currently included in U.S. Environmental Protection Agency (EPA) Method 8330B. Analytical methods were developed to enable sensitive, simultaneous detection and quantitation of the 24 IM and legacy compounds, including two orthogonal high-performance liquid chromatography (HPLC) column separations with either ultraviolet (UV) or mass spectrometric (MS) detection. Procedures were developed for simultaneous extraction of all 24 analytes and two surrogates (1,2-dinitrobenzene, 1,2-DNB; o-NBA) from high- and low-level aqueous matrices and solid matrices, using acidification, solid phase extraction (SPE), or solvent extraction (SE), respectively. The majority of compounds were recovered from four tissue types within current limits for solids, with generally low recovery only for Tetryl (from 4 to 62%). A preparatory chromatographic interference removal procedure was adapted for tissue extracts, as various analytical interferences were observed for all studied tissue types.
