No full textRichard Viidalepp (Widebaum before Estonianising his name, and later Viidebaum; Jan. 23, 1904 - June 3, 1986), the famous Estonian folklorist, was born in the Jalapuu farm in the village of Nurmsi in Central Estonia. The same farm was the home of Urve Buschmann, the author of the article and R. Viidalepp's niece. On the basis of the 1722 list of inhabitants in the Särgavere estate and the registers of the Järva Peetri congregation, the documented genealogy of Viidalepp's family starts with Jüri Jalapuu and his wife Els (?1730-?1761). In more recent registers their son Jüri (?1771-1843) already appears under the name Widebaum. The family was a typical Estonian family, including farmers, handicraftsmen, inventive technicians, later also intellectuals and artists. Some emigrated (the Finnish and American branches of the Viidebaums) and some were deported to Siberia. The fate of family members and descriptions of family history are illustrated by Richard Viidalepp's letters and family photographs. The last Viidalepps born in the Jalapuu farm moved to Tallinn in 1950
A fluorescent host-guest complex of cucurbituril in solution: a molecular Jack O'Lantern
No full textFluorescence enhancement of a probe molecule in solution by the container molecule cucurbituril (CB) is reported for the first time. The fluorescence of the probe 2-anilinonaphthalene-6-sulfonate (2,6-ANS) in aqueous Na2SO4 solution is found to increase by a maximum factor of 5.0 upon addition of cucurbituril. This fluorescence enhancement is the result of the formation of a host-guest inclusion complex, in which the guest 2,6-ANS is incorporated inside the cavity of the host, cucurbituril. Measurement of the enhancement as a function of cucurbituril concentration yielded a value of the equilibrium constant (K) of 52 +/- 10 M-1. It is proposed that the mode of inclusion involves the phenyl group of the 2,6-ANS, because of the relatively small size of the cucurbituril cavity. It is further proposed that the observed enhancement is a result of loss of rotational mobility of the phenyl ring relative to the naphthyl fluorophore of 2,6-ANS upon inclusion of the phenyl ring, Since the name cucurbituril is derived from the Latin word for "pumpkin," this fluorescent host-guest complex is referred to as a "molecular Jack O'Lantern," with the 2,6-ANS serving as the candle.PT: J; CR: BEHREND R, 1905, LIEBIGS ANN CHEM, V339, P1 BORTOLUS P, 1996, ADV PHOTOCHEMISTRY P, P1 BUSCHMANN HJ, 1992, J INCLUS PHENOM MOL, V14, P91 BUSCHMANN HJ, 1997, J INCLUS PHENOM MOL, V29, P167 BUSCHMANN HJ, 1998, THERMOCHIM ACTA, V317, P95 BUSCHMANN HJ, 1999, J PHOTOCH PHOTOBIO A, V121, P99 CINTAS P, 1994, J INCLUS PHENOM MOL, V17, P205 CRAM DJ, 1997, CONTAINER MOL THEIR DANTZ DA, 1998, SUPRAMOL CHEM, V9, P79 DELAPENA AM, 1993, J INCLUS PHENOM MOL, V15, P131 DIAMOND D, 1996, CHEM SOC REV, V25, P15 FREEMAN WA, 1981, J AM CHEM SOC, V103, P7367 HOFFMANN R, 1994, J CHEM SOC FARADAY T, V90, P1507 JEON YM, 1996, J AM CHEM SOC, V118, P9790 KOSOWER EM, 1975, J AM CHEM SOC, V97, P2167 KOSOWER EM, 1978, J AM CHEM SOC, V100, P4179 LI S, 1992, CHEM REV, V92, P1457 MOCK WL, 1983, J ORG CHEM, V48, P3618 MOCK WL, 1995, TOP CURR CHEM, V175, P1 MOCK WL, 1996, COMPREHENSIVE SUPRAM, V2, P477 WAGNER BD, 1998, J PHOTOCH PHOTOBIO A, V114, P151 WAGNER BD, 1999, J PHYS CHEM B, V103, P10114 WAGNER BD, 2000, J INCL PHENOM MACRO, V38, P467 WHANG DM, 1998, J AM CHEM SOC, V120, P4899; NR: 24; TC: 16; J9: CAN J CHEM; PG: 4; GA: 473RESource type: Electronic(1
Fluorescence enhancement of curcumin upon inclusion into cucurbituril
No full textThe effect of the macrocyclic host compounds cucurbit[n]urils (Qn), with n = 5 - 7, on the fluorescence of the biologically active compound curcumin has been studied. Curcumin, the main constituent of the Indian spice turmeric, is of growing interest because of its wide-ranging pharmaceutical properties. This compound forms strong 2:1 host-guest inclusion complexes with Q6 (the original cucurbituril), with an overall equilibrium constant of (1.9 +/- 0.8) X 10(4) M-2. It is postulated that a Q6 host partially encapsulates each of the two phenyl groups at the ends of the curcumin molecule. The difference in magnitude of the equilibrium constants K-1 (72 +/- 2 M-1) and K-1 (260 +/- 120 M-1) for stepwise encapsulation of the two ends of the curcumin molecule indicates that encapsulation by the first Q6 significantly alters its entire electronic structure, resulting in a more favorable second encapsulation. A very large enhancement of the fluorescence of curcumin results from this complex formation, on the order of 5.0; this is a significant fraction of the polarity sensitivity factor (PSF) of 39 measured for curcumin, that is the ratio of fluorescence intensity in ethanol vs. water. Surprisingly, no such enhancement could be observed in the case of Q7, indicating that the interactions between the guest and the host cavity are not favorable in this case, contrary to expectations. Similarly, no enhancement was observed in the case of Q5, which is not unexpected, because of the extremely small size of the host cavity and portal in this case.PT: J; CR: BARIK A, 2003, PHOTOCHEM PHOTOBIOL, V77, P597 BONG PH, 2000, B KOR CHEM SOC, V21, P81 BUSCHMANN HJ, 1997, J INCLUS PHENOM MOL, V29, P167 BUSCHMANN HJ, 1998, J SOLUTION CHEM, V27, P135 BUSCHMANN HJ, 1998, THERMOCHIM ACTA, V317, P95 BUSCHMANN HJ, 2000, J INCL PHENOM MACRO, V37, P231 BUSCHMANN HJ, 2000, SUPRAMOL CHEM, V11, P225 CHIGNELL CF, 1994, PHOTOCHEM PHOTOBIOL, V59, P295 CHOI S, 2002, MACROMOLECULES, V35, P3526 CINTAS P, 1994, J INCLUS PHENOM MOL, V17, P205 DAHL TA, 1994, PHOTOCHEM PHOTOBIOL, V59, P290 DALTON L, 2003, CHEM ENG NEWS SEP, P8 DAY A, 2001, J ORG CHEM, V66, P8094 DELAPENA AM, 1993, J INCLUS PHENOM MOL, V15, P131 ELHAOUAJ M, 2001, J CHEM SOC PERK NOV, P2104 ELHAOUAJ M, 2001, J CHEM SOC PERK T 2, P804 FREEMAN WA, 1981, J AM CHEM SOC, V103, P7367 FREEMAN WA, 1984, ACTA CRYSTALLOGR B, V40, P382 HAMAI S, 1996, B CHEM SOC JPN, V69, P2469 HOFFMANN R, 1994, J CHEM SOC FARADAY T, V90, P1507 JANSEN K, 2000, VOM WASSER, V95, P229 JEON YM, 1996, J AM CHEM SOC, V118, P9790 JOVANOVIC SV, 2001, J AM CHEM SOC, V123, P3064 KHOPDE SM, 2000, PHOTOCHEM PHOTOBIOL, V72, P625 KIM J, 2000, J AM CHEM SOC, V122, P540 LAGONA J, 2003, ORG LETT, V5, P3745 LEE JW, 2003, ACCOUNTS CHEM RES, V36, P621 LIU Y, 2000, J ORG CHEM, V65, P6227 MARQUEZ C, 2001, ANGEW CHEM INT EDIT, V40, P3155 MARQUEZ C, 2001, ANGEW CHEM INT EDIT, V40, P4387 MESCHKE C, 1997, THERMOCHIM ACTA, V297, P43 MOCK WL, 1983, J ORG CHEM, V48, P3618 MOCK WL, 1986, J ORG CHEM, V51, P4440 MOCK WL, 1989, J AM CHEM SOC, V111, P2697 MOCK WL, 1990, J CHEM SOC CHEM COMM, P1509 MOCK WL, 1995, TOP CURR CHEM, V175, P1 MOCK WL, 1996, COMPREHENSIVE SUPRAM, V2, P477 NEUGEBAUER R, 1998, J CHEM SOC PERK MAR, P529 NIGAM S, 1996, J PHYS CHEM-US, V100, P7135 ROBINSON TP, 2003, BIOORG MED CHEM LETT, V13, P115 SHIM JS, 2003, CHEM BIOL, V10, P695 SUN YM, 2002, ORG LETT, V4, P2909 SZELTLI J, 1998, CHEM REV, V98, P1743 TANG B, 2002, J AGR FOOD CHEM, V50, P1355 TONNESEN HH, 2002, INT J PHARM, V244, P127 WAGNER BD, 2000, J INCL PHENOM MACRO, V38, P467 WAGNER BD, 2001, CAN J CHEM, V79, P1101 WAGNER BD, 2003, J PHYS CHEM B, V107, P10741 WHANG D, 1996, J AM CHEM SOC, V118, P11333 WHANG D, 1998, ANGEW CHEM INT EDIT, V37, P78 WRIGHT JS, 2002, J MOL STRUC-THEOCHEM, V591, P207; NR: 51; TC: 8; J9: SUPRAMOL CHEM; PG: 7; GA: 876JJSource type: Electronic(1

Mediating policing in the "fight against crime" and "rural terrorism" in Chile
No full textThis electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Thesis: S.M. in Comparative Media Studies, Massachusetts Institute of Technology, Department of Comparative Media Studies/Writing, 2019Cataloged from PDF version of thesis.Includes bibliographical references (pages 129-136).From drones to predictive policing systems, there has been an increasing incorporation of new security technologies over the last years in Chile to make the fight against crime and "rural terrorism" more effective, in a context marked by a persistent attention to feelings of insecurity. Even though surrounded by an aura of neutrality, these technologies are far from neutral, as they form part of a complex sociocultural fabric of people, practices, discourses, legal frameworks and institutions. Furthermore, instead of solving problems more effectively, these technologies are complicating preexisting tensions. This thesis delves into a critical study of the contemporary anatomy of power, in which mediation processes are becoming central to policing practices, with a focus on two contexts: the fight against crime in urban areas, and the battle against "rural violence" or "terrorism" in the Mapuche indigenous territories in the south of Chile.Drawing on media theories and governmentality studies, I offer the term operational atmospheres as a notion to think with and account for the composition of policing practices at the cross of vertical (aerial, orbital, and electromagnetic), algorithmic, and affective fields of actions. Operational atmospheres are entanglements of feelings, imaginaries, and discursive practices; technologies and techniques; local and transnational political economies and histories; that form perceptual systems, ways of seeing or sensing like a state which are contingent, partial and grounded on fragile and labor intensive processes, through which they come into existence. I take as a methodological framework Donna Haraway's situated knowedges to locate and shed light on the processes of manufacturing state's logistics of perception and their consequences on the (re)production and government of others' spaces and subjects, in this case, the Mapuche as a "terrorist", and the criminal in urban areas.In the context of "rural terrorism", I examine three police operations: the killing of Camilo Catrillanca by Comando Jungla; the fake intelligence police operation, Operacidn Huracdn; and the introduction of aerial surveillance in the "red zone". Through this analysis, I shed light on the central role mediation processes play to produce imaginaries of the Mapuche as criminals and terrorists, and to sustain the development of special police operations to target, deceive and incriminate Mapuche in the context of their mobilization to recover lands and autonomy, crossing colonial pasts, neoliberal extractive presents, and global security discourses and practices. I then examine the informational, algorithmic, and unmanned aerial systems mediating carabineros'work in urban spaces, conceived as the location of calculable risks mobilizing preemptive actions to affect feelings of (in)security.By the implementation of a local version of CompStat, the integration of predictive policing, and the use of drones, urban policing has increasingly expanded beyond the realm of preemptive actions into the formation of "safety" ambiances, becoming atmospheric, pervasive, and affective. More than answers, this thesis opens up contemporary mechanisms of security operating in Chile, to denaturalize and dismantle the neutrality and effectiveness attached to the implementation of new technologies in policing.by Josefina Buschmann Mardones.S.M. in Comparative Media StudiesS.M.inComparativeMediaStudies Massachusetts Institute of Technology, Department of Comparative Media Studies/Writin
Identification and characterization of the novel subunit CcoM in the cbb₃-Cytochrome c oxidase from Pseudomonas stutzeri ZoBell
No full textCytochrome c oxidases (CcOs), members of the heme-copper containing oxidase (HCO) superfamily, are the terminal enzymes of aerobic respiratory chains. The cbb3-type cytochrome c oxidases (cbb3-CcO) form the C-family and have only the central catalytic subunit in common with the A- and B-family HCOs. In Pseudomonas stutzeri, two cbb3 operons are organized in a tandem repeat. The atomic structure of the first cbb3 isoform (Cbb3-1) was determined at 3.2 Å resolution in 2010 (S. Buschmann, E. Warkentin, H. Xie, J. D. Langer, U. Ermler, and H. Michel, Science 329:327-330, 2010, http://dx.doi.org/10.1126/science.1187303). Unexpectedly, the electron density map of Cbb3-1 revealed the presence of an additional transmembrane helix (TMH) which could not be assigned to any known protein. We now identified this TMH as the previously uncharacterized protein PstZoBell_05036, using a customized matrix-assisted laser desorption ionization (MALDI)-tandem mass spectrometry setup. The amino acid sequence matches the electron density of the unassigned TMH. Consequently, the protein was renamed CcoM. In order to identify the function of this new subunit in the cbb3 complex, we generated and analyzed a CcoM knockout strain. The results of the biochemical and biophysical characterization indicate that CcoM may be involved in CcO complex assembly or stabilization. In addition, we found that CcoM plays a role in anaerobic respiration, as the ΔCcoM strain displayed altered growth rates under anaerobic denitrifying conditions.om Pseudomonas stutzeri, a bacterium closely related to the human pathogen Pseudomonas aeruginosa
