Published: December 2014

Objectives

In 1828, between 8,000 and 15,000 Indians from the Jesuit Missions were brought to Uruguay. There, they were settled in a village, presently named Bella Unión, in the northwest corner of the country. According to historic sources, the Indians abandoned the settlement shortly thereafter, with the village subsequently repopulated by “criollos” and immigrants from abroad. As a first approach to reconstruct the genetic history of the population, data about the living population genetic structure will be used. Based on the analysis of the maternal lineages of the inhabitants of Bella Unión, and of those from two nearby villages, we expect to partially answer what happened with the first and subsequent inhabitants.

Methods

We analyzed the maternal lineages of the present inhabitants of Bella Unión and neighboring localities through the sequencing of the mitochondrial DNA control region.

Results

A total of 64.3%, 5.7%, and 30% of the mtDNAs were of Native, African, and West Eurasian origin, respectively. These figures are quite similar to that of the population of Tacuarembó, which is located in northeastern Uruguay. The four main Native American founding haplogroups were detected, with B2 being the most frequent, while some rare subhaplogroups (B2h, C1b2, D1f1) were also found. When compared with other Native American sequences, near‐ matches most consistently pointed to an Amazonian Indian origin which, when considered with historical evidence, suggested a probable Guaraní‐Missionary‐related origin.

Conclusions

The data support the existence of a relationship between the historic and present inhabitants of the extreme northwest Uruguay, with a strong contribution of Native Americans to the mitochondrial DNA diversity observed there. Am. J. Hum. Biol. 27:407–416, 2015. © 2014 Wiley Periodicals, Inc.
Poröse und formanisotrope Einkristalle des Halbleiter‐Perowskits CH3NH3PbI3 aus einer neuen Single‐Source‐Vorstufe
Authors: Kollek Tom , Gruber Dominik , Gehring Julia , Zimmermann Eugen , Schmidt‐Mende Lukas , Polarz Sebastian
Published: December 2014

Signifikante Fortschritte in der Solarzellforschung werden aktuell von der Substanzklasse der metallorganischen Perowskite (MOPs) dominiert. Ursächlich dafür sind herausragende Eigenschaften dieser Materialien, wie hohe Absorptionskoeffzienten und die Fähigkeit zur effektiven Trennung photogenerierter Ladungsträger. In Analogie zu etablierteren Halbleitern kann erwartet werden, dass die Materialeigenschaften auch der MOPs durch eine definierte Nanostrukturierung stark verbessert werden können. Ihre chemische Anfälligkeit (z. B. gegen Hydrolyse) erschwert aber die direkte Übertragung gängiger Verfahren zur Herstellung von Nanomaterialien. Wir berichten über einen originären Ansatz zur Synthese verschiedener (CH3NH3)PbI3‐Nanostrukturen unter Verwendung einer neuartigen Single‐Source‐Vorstufe. Nanoporöse MOP‐Einkristalle können durch eine Kristall‐Kristall‐Umwandlung erhalten werden, die mit einer spinodalen Mikrophasenseparation der Triethylenglykol‐haltigen Vorstufenverbindung einhergeht. Die Steuerung der Nanopartikelform gelingt durch Einsatz eines selektiv bindenden Kristallisationsinhibitors.
Highly soluble and thermally stable copolyimides modified with trifluoromethyl and siloxane
Authors: Yao Pan , Gu Junwei , Lei Xingfeng , Sun Wanlu , Chen Ying , Zhang Qiuyu
Published: December 2014

A series of highly soluble aromatic polyimides with excellent thermal properties were fabricated by traditional two‐step polycondensation reaction of dianhydride monomer 4,4′‐(4,4′‐isopropylidenediphenoxy)bis(phthalic anhydride) or 4,4‐(hexafluoroisopropylidene)diphthalic anhydride with diamine monomer 1,3‐bis(4‐aminophenoxy)benzene or 1,3‐bis(3‐aminopropyl) tetramethyldisiloxane in N,N‐dimethylacetylamide solvent. Results revealed that copolyimide of PI‐4 containing trifluoromethyl and tetramethyldisiloxane possessed excellent solubility and remarkable thermal properties. PI‐4 could dissolve well in common low boiling point solvents such as THF of up to 80 mg/mL and acetone of 40 mg/mL. Moreover, the 10% weight loss temperature of the PI‐4 was 539°C and the Tg value of the PI‐4 was 311°C. PI‐4 might be easily cast into flexible and tough films applied in optoelectronic devices. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41713.
Preparation of bi‐modified amphoteric oligochitosan derivatives and electrochemical evaluation on anticorrosion performances
Authors: Zhang Huixin , Wang Dongdong , Jin Xiuhong , Yang Tingru , Shen Xiaoli
Published: December 2014

Four bi‐modified amphoteric oligochitosan derivatives were synthesized chemically using quaternization, sulfonation, and carboxylation. The anticorrosion characteristics and mechanism of anticorrosion of these four oligochitosan derivatives on Q235 steel in 1.0 mol/L HCl solution were studied by potentiodynamic polarization and electrochemical impedance spectroscopy at constant temperature. The results suggest that these derivatives are hybrid corrosion inhibitors in which anodic inhibition predominates following the mechanism of adsorption film formation on the surface of the metal. They all have their own optimal dosages for anticorrosion application. Their inhibiting efficiencies are closely related to the nature and the amount of heteroatoms in their molecules. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41714.
A chromosome separation checkpoint
Authors: Maiato Helder , Afonso Olga , Matos Irina
Published: December 2014

Here we discuss a “chromosome separation checkpoint” that might regulate the anaphase‐telophase transition. The concept of cell cycle checkpoints was originally proposed to account for extrinsic control mechanisms that ensure the order of cell cycle events. Several checkpoints have been shown to regulate major cell cycle transitions, namely at G1‐S and G2‐M. At the onset of mitosis, the prophase‐prometaphase transition is controlled by several potential checkpoints, including the antephase checkpoint, while the spindle assembly checkpoint guards the metaphase‐anaphase transition. Our hypothesis is based on the recently uncovered feedback control mechanism that delays chromosome decondensation and nuclear envelope reassembly until effective separation of sister chromatids during anaphase is achieved. A central player in this potential checkpoint is the establishment of a constitutive, midzone‐based Aurora B phosphorylation gradient that monitors the position of chromosomes along the spindle axis. We propose that this surveillance mechanism represents an additional step towards ensuring mitotic fidelity.
Die Invasion der Stechmücken
Authors: Becker Norbert , Jöst Artur , Storch Volker
Published: December 2014

Die Wissenschaftler der “Kommunalen Aktionsgemeinschaft zur Bekämpfung der Stechmücken” (KABS) und der Universität Heidelberg haben von 1995 bis 2011 vier neue Stechmückenarten als Neozoen für Deutschland nachweisen können. Aedes albopictus und Ochlerotatus j. japonicus sind im Rahmen der Globalisierung mit Handelsgütern bzw. als blinde Passagiere in Kraftfahrzeugen nach Deutschland eingeschleppt worden. Insbesondere die Ausbreitung von Ae. albopictus wird durch die Klimaerwärmung begünstigt. Die rapide Ausbreitung von Ae. albopictus und Oc. j. japonicus sowie die damit verbundenen Risiken der Übertragung von Krankheitserregern, insbesondere von Arboviren auf den Menschen, haben dazu geführt, dass die Culicidenforschung erneut im Fokus der Wissenschaft steht.

Thermodynamic Properties of CO2 Conversion by Sodium Borohydride
Authors: Zhao Yi , Zhang Zili
Published: December 2014

In order to verify the resource utilization of CO2 from coal‐fired flue gas, the conversion of CO2 by sodium borohydride was investigated under atmospheric pressure and moderate temperature. According to the product analysis results of mass spectrometry and ion chromatography, combined with the comparison of electrode potentials, the mechanism of CO2 reaction with sodium borohydride was deduced, in which formate was confirmed as the main reduction product, and the intermediates of [BHi(HCO2)(OH)3–i]−1 were considered as the essential mediums for the formation of formate. The feasibility of this conversion was studied thermodynamically.

Interaction effects between weather and space use on harvesting effort and patterns in red deer
Authors: Rivrud Inger M. , Meisingset Erling L. , Loe Leif E. , Mysterud Atle
Published: December 2014

Most cervid populations in Europe and North America are managed through selective harvesting, often with age‐ and sex‐specific quotas, with a large influence on the population growth rate. Less well understood is how prevailing weather affects harvesting selectivity and off‐take indirectly through changes in individual animal and hunter behavior. The behavior and movement patterns of hunters and their prey are expected to be influenced by weather conditions. Furthermore, habitat characteristics like habitat openness are also known to affect movement patterns and harvesting vulnerability, but how much such processes affect harvest composition has not been quantified. We use harvest data from red deer (Cervus elaphus) to investigate how weather and habitat characteristics affect behavioral decisions of red deer and their hunters throughout the hunting season. More specifically, we look at how sex and age class, temperature, precipitation, moon phase, and day of week affect the probability of being harvested on farmland (open habitat), hunter effort, and the overall harvest numbers. Moon phase and day of week were the strongest predictors of hunter effort and harvest numbers, with higher effort during full moon and weekends, and higher numbers during full moon. In general, the effect of fall weather conditions and habitat characteristics on harvest effort and numbers varied through the season. Yearlings showed the highest variation in the probability of being harvested on farmland through the season, but there was no effect of sex. Our study is among the first to highlight that weather may affect harvesting patterns and off‐take indirectly through animal and hunter behavior, but the interaction effects of weather and space use on hunter behavior are complicated, and seem less important than hunter preference and quotas in determining hunter selection and harvest off‐take. The consideration of hunter behavior is therefore key when forming management rules for sustainable harvesting.
Population divergence in compensatory growth responses and their costs in sticklebacks
Authors: Ab Ghani Nurul Izza , Merilä Juha
Published: December 2014

Compensatory growth (CG) may be an adaptive mechanism that helps to restore an organisms’ growth trajectory and adult size from deviations caused by early life resource limitation. Yet, few studies have investigated the genetic basis of CG potential and existence of genetically based population differentiation in CG potential. We studied population differentiation, genetic basis, and costs of CG potential in nine‐spined sticklebacks (Pungitius pungitius) differing in their normal growth patterns. As selection favors large body size in pond and small body size in marine populations, we expected CG to occur in the pond but not in the marine population. By manipulating feeding conditions (viz. high, low and recovery feeding treatments), we found clear evidence for CG in the pond but not in the marine population, as well as evidence for catch‐up growth (i.e., size compensation without growth acceleration) in both populations. In the marine population, overcompensation occurred individuals from the recovery treatment grew eventually larger than those from the high feeding treatment. In both populations, the recovery feeding treatment reduced maturation probability. The recovery feeding treatment also reduced survival probability in the marine but not in the pond population. Analysis of interpopulation hybrids further suggested that both genetic and maternal effects contributed to the population differences in CG. Hence, apart from demonstrating intrinsic costs for recovery growth, both genetic and maternal effects were identified to be important modulators of CG responses. The results provide an evidence for adaptive differentiation in recovery growth potential.
Improved Electrical Energy Storage Density in Vanadium‐Doped BaTiO3 Bulk Ceramics by Addition of 3BaO–3TiO2–B2O3 Glass
Authors: Patel Satyanarayan , Chauhan Aditya , Vaish Rahul
Published: December 2014

This study proposes to significantly improve the electrical energy storage characteristics of BaTiO3 bulk ceramics. Addition of 3 BaO–3 TiO2–B2O3 glass was done in controlled amounts to study its effect on the ferroelectric response and storage characteristics of vanadium‐doped BaTiO3 samples. The energy density for the composites was calculated using hysteresis loops. It was observed that a significant improvement in the energy storage density can be obtained by addition of 1 % (weight) 3 BaO–3 TiO2–B2O3 glass. The addition of glass in small amounts was also observed to impart additional benefits such as increased saturation polarization and a thermally invariant ferroelectric response.
Aquifer–peatland connectivity in southern Quebec (Canada)

Published: December 2014

In areas where peatlands are abundant, they are likely to play a significant role in the hydrological and hydrogeological dynamics of a watershed. Although individual case studies are reported in the literature, there is a large range of aquifer–peatland interactions and there is a need to understand the controls of these interactions. The objectives of this study were (1) to better understand aquifer–peatland connections and how these may be predicted by geology and geomorphic location and (2) to provide a variety of reference sites for glacial geological settings. Slope and depression peatlands were studied in the Abitibi‐Témiscamingue region and in the St. Lawrence Lowlands, two contrasting regions of southern Quebec. A total of 12 transects that span a shallow aquifer–peatland interface were instrumented with piezometers. Field investigations included peatland characterization, monthly water level monitoring, and continuous hydraulic head measurements with pressure transducers. The results indicate that 7 of the 12 transects receive groundwater from the surrounding shallow aquifer. At the peatland margin, four lateral flow patterns were identified and associated with slope peatlands (parallel inflow and divergent flow) and with depression peatlands (convergent flow and parallel outflow). Vertical hydraulic gradients suggest that water flows mainly downwards, i.e. from the peatland to the underlying mineral deposits. Vertical connectivity appears to decrease as the distance from the peatland margin increases. All of these exchanges are important components in the sustainability of peatland hydrogeological functions. The regional comparison of aquifer–peatland flow dynamics performed in this study provides a new set of referenced data for the assessment of aquifer–peatland connectivity.
