Past human impact and pollutant loading reconstruction in Lake Engure as a tool for lake basin management

Abstract Environmental pollution of lakes and rivers is considered as one of the most important environmental problems. Analysis of nutrient and trace element accumulation in sedimentary phases of lakes can reflect the overall regional pollution level, and the observed accumulation patterns of pollutants in sediment profiles can be used to reconstruct the history of anthropogenic impacts. As pollutants in sediments are associated with other substances, it is important not only to study total concentrations of pollutants, but also their speciation forms. The aim of this study was to describe phosphorus (including speciation forms) and trace element concentrations in sediment profiles of Lake Engure and to evaluate human impact on organic matter accumulation and properties in lake sediments. The concentrations of the studied elements in sediments of Lake Engure are at background levels, which is clearly evident when compared with metal concentrations in lake sediments in West European countries. The analysis of element concentration changes in sedimentary profiles provided information about trends in recent accumulation (within the last 100 years) and on the balance between natural and human-induced accumulation processes. Analysis of nutrient concentrations in sediments aided in identifying background values as targets for lake management activities. Abstract in Latvian Upju un ezeru piesārņojums ir uzskatāms par vienu no nozīmīgākajām vides problēmām. Biogēno elementu un toksisko mikroelementu uzkrāšanās nogulumos atspoguļo piesārņojumu sateces baseinā, bet piesārņojošo vielu akumulācijas analīze nogulumu profilos ļauj izsekot cilvēku ietekmes mainībai reģionā. Tomēr, tā kā piesārņojošās vielas ir saistītas ar citām vielām nogulumos, svarīgi ir analizēt ne tikai vielu kopējās koncentrācijas, bet arī to atrašanās formas. Šī pētījuma mērķis ir analizēt fosfora un mikroelementu koncentrācijas un fosfora savienojumu atrašanās formu mainību Engures ezera nogulumu profilos un noteikt antropogēno ietekmju raksturu uz organisko vielu uzkrāšanos un nogulumu īpašībām. Pētīto elementu koncentrācijas Engures ezera nogulumos ir fona koncentrāciju līmenī, īpaši, ja salīdzina ar koncentrācijām Rietumeiropas valstu ūdenstilpju nogulumos. Tomēr elementu koncentrāciju analīze nogulumu profilos ļauj izsekot antropogēnās slodzes intensitātes mainībai pēdējo 100 gadu laikā un pamatot nepieciešamās rīcības ezera ilgtspējīgas apsaimniekošanas risinājumu nodrošināšanai. Biogēno elementu koncentrācijas noteikšana ezera nogulumos ļauj noteikt to fona koncentrāciju līmeņu ezeru kopšanas pasākumu īstenošanai.
Out-of-Plane Aptamer Functionalization of RNA Three-Helix Tiles

Co-transcriptionally folding RNA nanostructures have great potential as biomolecular scaffolds, which can be used to organize small molecules or proteins into spatially ordered assemblies. Here, we develop an RNA tile composed of three parallel RNA double helices, which can associate into small hexagonal assemblies via kissing loop interactions between its two outer helices. The inner RNA helix is modified with an RNA motif found in the internal ribosome entry site (IRES) of the hepatitis C virus (HCV), which provides a 90° bend. This modification is used to functionalize the RNA structures with aptamers pointing perpendicularly away from the tile plane. We demonstrate modifications with the fluorogenic malachite green and Spinach aptamers as well with the protein-binding PP7 and streptavidin aptamers. The modified structures retain the ability to associate into larger assemblies, representing a step towards RNA hybrid nanostructures extending in three dimensions.
Standardization of the Compass Neuropils of the Australian Bogong Moth, Agrotis infusa

Every summer the Australian Bogong moth migrates from southern Queensland to the Australian Alps in southern New South Wales. Other migrants such as the monarch butterfly use a time-compensated sun compass. However, the Bogong is nocturnal and only has access to skylight cues such as the moon, polarized light or the Milky Way. Since these are considerably unreliable only being visible short periods of time, another navigational mechanism could be a magnetic compass. In the Monarch the brain regions (neuropils) involved in navigation are the central complex, the lateral accessory lobes and the anterior optic tubercles; which together are called the ‘compass neuropils’. As the brain anatomy is the structural basis for all information processing underlying orientation and navigation, it can be used as an access point to understand this extraordinary migratory behaviour. We therefore performed 3D-reconstruction of the compass neuropils of the Bogong moth brain. By generating a standardized version of the compass neuropils I have created a common frame of reference for registration of neuron morphologies and networks, as well as providing reference volumes that were compared to those of the monarch. The Bogong moth brain was found to contain all the compass neuropils, however there was a significant difference between the two species neuropil-volumes. Interestingly, all components of the central complex were larger in the Bogong, while the upper unit of the anterior optic tubercle was substantially larger in the Monarch. (Less)
THE CONTRIBUTION OF TERRASAR-X DATA FOR GEODYNAMICS AND ENGINEERING STUDIES

Space-borne Interferometric Synthetic Aperture Radar (InSAR) is nowadays one of the most preferred geodetic methods to assess ground deformation associated with natural and anthropogenic hazards. Our capabilities for hazard monitoring have been further enhanced thanks to the highresolution X-band radar data provided by the German TerraSAR-X satellite. Time-series InSAR using X-band data with short-revisit and regular schedule makes the long-term monitoring of small displacement with millimetric precision more feasible. In this study, we present an overview of some findings and results obtained in several projects where TSX InSAR observations contributed to investigate dynamic deformation associated with earthquake cycle and postseismic processes in New Zealand, land subsidence due to subsurface fluid flow extraction in Tehran, Iran, landslide creep in Kyrgyzstan, and differential movement of bridge approach embankments in northwest Iran.
Sobre a experiência sexual dos jovens

The rise in teenage pregnancy and young people's vulnerability to HIV have been a serious problem. This paper is intended to confront this statement based on its structural concepts (adolescence, youth, teenage pregnancy, and vulnerability) and by a non-exhaustive review of the relevant literature. The current paper discusses the ideas of youth and adolescence to approach the sexuality of young people and adolescents from the perspective of inequalities between different social groups and their access to health and resources for the prevention of diseases like HIV/AIDS as well as contraception. There are multiple paths leading young people to having unprotected sexual relations, and the numbers that surface on pregnancy, STDs, and HIV infection are doubtless lower than the real figures. The data presented herein indicate that the safe-sex approach is still necessary among youth, requiring efforts to produce creative strategies that make sense in different socio-cultural contexts in which young people experience sex.
Preferences, trust and willingness to pay for food information: An analysis of the Italian Market

Lack of consumer trust and communication strategies are probably the main determinants of information failure in modern food markets. This study attempts to tackle these aspects affecting the quality of food information by investigating questions related to what topics are more relevant to consumers, who should disseminate trustful food information, and how communication should be conveyed. Primary data were collected both through qualitative (in depth interviews and focus groups) and quantitative research. Quantitative research was conducted by means of a questionnaire administered in 2006-2007 to a sample of Italian respondents using both a web and a traditional mail survey. Reading preferences, willingness to pay and trust towards public and private sources conveying information through a hypothetical food magazine were assessed combining factor analysis, choice modelling and a criterion-based market segmentation. The study shows that reading preferences of Italian consumers can be summarized along three dimensions: agro-food system, enjoyment and wellness. Furthermore, willingness to pay for receiving food-related information is influenced by trust towards the type of publisher, which plays also a key role in market segmentation together with socio-demographic and economic variables such as gender, age, presence of children and income. Policy implications of these findings are discussed.
Securitizing capital: A processual-relational approach to pluralized security

In this article, we introduce the concept of ‘securitizing capital’ as a new analytical tool to understand the pluralized landscape of security. We define securitizing capital as a process whereby different forms of capital are, consciously and unconsciously, used to acquire legitimacy and power. While other approaches have been developed to understand pluralized security, such as security networks, nodal frameworks and assemblages, we argue that, useful as they are, they tend to overlook issues of agency, how relationships are established and negotiated and the subjective experiences of security. In contrast, we introduce a processual-relational approach that is based on the translation and conversion of other types of capital, such as economic and social, to acquire a position of power within a specific (security) ‘field’. In order to elaborate on our approach and its relevance, we draw on fieldwork conducted in Kenya, Jamaica and Israel.
FLT 3 Mutation Status is a Predictor of Early Death in Pediatric Acute Promyelocytic Leukemia : A Report From The Children ' s Oncology Group

Background—FLT3 mutations (FLT3/Mut) are prevalent in de novo AML and are associated with early relapse. The prevalence and prognostic significance of FLT3/Mut have not been well defined in childhood acute promyelocytic leukemia (APL). Procedure—Diagnostic specimens from 104 pediatric APL patients were screened for FLT3/ Mut (FLT3/ITD or FLT3/ALM). FLT3/Mut status was correlated with disease characteristics and clinical outcome for patients treated on CALGB C9710 (N=50). Corresponding Author: Matthew A.

N IH PA Athor M anscript N IH PA Athor M anscript N IH PA Athor M anscript Results—Forty-two of the 104 patients (40%) had either FLT3/ITD (N=28, 27%) or FLT3/ALM (N=15, 14%). Median diagnostic WBC count was 23,400 cells/uL vs. 3,600 cells/uL for those with and without FLT3/Mut (p <0.001), and similar results for the cohort of 50 patients treated on C9710 (p <0.001). In patients treated on C9710, presence of a FLT3 mutation was highly correlated with diagnostic WBC count >10,000 (p=0.004), microgranular variant histology (p=0.035), and a lower remission rate (p=0.009). In patients who received ATRA (C9710 or CCG-2911, n=58), those with FLT3/Mut had an induction death rate of 30% (7/23) compared to 3% (1/35) in FLT3/WT patients (p=0.005). In patients with high WBC counts (>10,000), those with FLT3/Mut had a significantly higher risk of induction death versus FLT3/WT patients (47% vs. 0%, p=0.05). FLT3/Mut was not associated with adverse outcome in those who survived induction therapy. Conclusions—FLT3/Mut are prevalent in pediatric APL and are associated with high WBC count and increased induction death. This study provides further evidence for testing APL patients for FLT3/Mut and the potential role for FLT3 inhibitors in this disease.

Evaluation of Hydrocarbon Generated and Expelled from the Jurassic to Early Cretaceous Source Rocks in the Lynedoch Field, Northern Bonaparte Basin, Australia

The Lynedoch field is located on the west flank of the Calder Graben in the north-eastern Bonaparte Basin, Australia. The data from the wells Lynedoch 1 and Lynedoch 2 and Seismic Line N11809 were used to reconstruct the burial and thermal histories and evaluate the hydrocarbon generated and expelled from the Jurassic to Early Cretaceous source rocks of the study area. Basin Mod 1-D and 2-D softwares were used for modeling. The Upper Jurassic Cleia (Lower Frigate) and Lower Cretaceous Echuca Shoals formations source rocks in the well Lynedoch 1 were a fair-to-good source richness with poor hydrocarbon generating potential, showing kerogen type III and gas prone. The Middle Jurassic Plover Formation source rock in the well Lynedoch 2 was a good organic matter richness with poor hydrocarbon generative potential, the late Middle Jurassic (Callovian) Elang Formation source rock in the same well was a fair source rock with poor hydrocarbon generation potential, and the Lower Cretaceous Echuca Shoals Formation source rock in the same well was a fair-to-very good organic richness with poor-to-fair hydrocarbon generating potential, gas prone with kerogen type III, and reaching wet gas window at present day. These previous formations of the both wells generated oil at the Late Cretaceous and gas at the Early Neogene. But, only Echuca Shoals Formation source rock in the well Lynedoch 2 was able to expelled hydrocarbon at the Middle Paleogene and continued up to present day. This Formation represents fair to slightly good potential source rock in the Lynedoch field.

EFFECT OF METFORMIN AND SIMVASTATIN IN DIAZEPAM-AND SODIUM NITRITE-INDUCED ANTEROGRADE AMNESIA IN MALE SWISS ALBINO MICE

Objective: To study the effect of metformin and simvastatin on diazepam-and sodium nitrite-induced anterograde amnesia in male Swiss albino mice.Methods: A total of 56 healthy male Swiss albino mice weighing 20–30 g were included in the study Mice were divided into seven groups (n=8) and received a specific dosage of drugs including metformin and simvastatin. Anterograde amnesia was induced by diazepam and sodium nitrite. Morris water maze paradigm was used to study amnesia in which the mice were trained to locate a hidden platform by releasing them into the opaque water for four times a day for four consecutive days. The acquisition of this task was evaluated by measuring escape latency time on all the days of study and by measuring the index of retrieval on day 5 of the study. These observations were compared among the test groups and drug-induced amnesia groups. The time was expressed as mean±standard error of the mean.Results: Significant reduction in the mean escape latency time (25.25 ± 5.09 s) and index of retrieval (52.38 ± 3.55 s) was observed in groups administered with sodium nitrite and metformin (p<0.001). In groups administered with sodium nitrite and simvastatin, the mean escape latency time and index of retrieval were 47.66 ± 7.69 s and 40.75 ± 4.13 s, respectively (p<0.05)). In addition, metformin completely ameliorated sodium nitrite-induced anterograde amnesia.Conclusion: Metformin and simvastatin ameliorated sodium nitrite-induced anterograde amnesia pointing toward a possible antioxidant role and can, therefore, be used to potentially inhibit oxidative stress-induced neurodegeneration. However, the pleiotropic roles of metformin and simvastatin are the areas that warrant further investigation before their clinical use.
A Survey of Seyfert AGN: Nuclear Gas Disks and Direct Black Hole Mass Estimates

Abstract In a survey of 18 nearby Seyfert nuclei, we find evidence for geometrically thick gas disks on scales of tens of parsecs. Mapping the interstellar medium traced by H2 ν = 1–0 S(1) emission using the infrared integral field spectrometers OSIRIS and SINFONI reveals general disk rotation with an additional significant component of random bulk motion implied by the high local velocity dispersion. The size scale of the typical nuclear gas disk is ~30 pc in radius with a comparable vertical height, and the distribution and kinematics suggest the gas is spatially mixed with the nuclear stellar population. Based on the estimated characteristic gas mass fraction of 10%, the average gas mass within this region is ~107M⊙. This suggests column densities of NH ~ 5 × 1023 cm−2, but the significantly lower densities implied by the stellar continuum extinction indicate that the gas distribution on these scales is dominated by dense clumps. We discuss the feasibility of constraining the masses of the central black holes via modeling of the gas disk kinematics, highlighting the importance of properly accounting for the gas velocity dispersion, and the use of these direct mass estimates to calibrate masses derived from the method of reverberation mapping.
Bulk Randall-Sundrum models, electroweak precision tests, and the 125 GeV Higgs

We present up-to-date electroweak fits of various Randall-Sundrum (RS) models. We consider the bulk RS, deformed RS, and the custodial RS models. For the bulk RS case we find the lightest Kaluza-Klein (KK) mode of the gauge boson to be similar to 8 TeV, while for the custodial case it is similar to 3 TeV. The deformed model is the least fine-tuned of all which can give a good fit for KK masses < 2 TeV depending on the choice of the model parameters. We also comment on the fine-tuning in each case.
2018-17 Peer-Induced Beliefs Regarding College Participation

Dedewanou: Department of Economics, Université Laval, CRREP, finagnon-antoine.dedewanou. 1@ulaval.ca Arnaud Dufays: Department of Economics, Université Namur, Associate professor, Université Laval, Arnaud.Dufays@unamur.be We study peer effects on the formation of beliefs regarding college participation. We present a structural model of learning in friendship networks. We show that the model is identified and we present a Bayesian estimation procedure. We estimate the model using data on teenagersʼ beliefs regarding college participation, controlling for preferences and academic achievement. We find that, on average, friendsʼ beliefs account for about 12% of the updating process. We also find strong heterogeneity among schools and individuals. In particular, we find substantial unobserved individual heterogeneity, which casts doubt on the efficiency of network-targeted public policies. JEL Codes: D83, I20, C31, C11
Effective-one-body Hamiltonian with next-to-leading order spin-spin coupling

We propose a way of including the next-to-leading (NLO) order spin-spin coupling into an effective-one-body (EOB) Hamiltonian. This work extends [S. Balmelli and P. Jetzer, Phys. Rev. D 87, 124036 (2013)], which is restricted to the case of equatorial orbits and aligned spins, to general orbits with arbitrary spin orientations. This is done applying appropriate canonical phase-space transformations to the NLO spin-spin Hamiltonian in Arnowitt-Deser-Misner (ADM) coordinates, and systematically adding "effectiv" quantities at NLO to all spin-squared terms appearing in the EOB Hamiltonian. As required by consistency, the introduced quantities reduce to zero in the test- mass limit. We expose the result both in a general gauge and in a gauge-fixed form. The last is chosen such as to minimize the number of new coefficients that have to be inserted into the effective spin squared. As a result, the 25 parameters that describe the ADM NLO spin-spin dynamics get condensed into only 12 EOB terms.
Polymorphisms of MBL Gene Introns and Their Association with MBL Serum Levels in Hu Sheep

PCR single-strand conformation polymorphism (SSCP) and DNA sequencing techniques were used to analyze the genetic polymorphism of mannose-binding lectin (MBL) gene 3 introns in Hu sheep. The results showed that 3 introns of MBL gene had polymorphism, 3 genotypes were identified in intron1, which were controlled by 2 alleles, respectively; 3 genotypes were identified in intron2, which were controlled by 2 alleles, respectively; 3 genotypes were identified in intron3, which were controlled by 2 alleles, respectively; 6 new single nucleotide polymorphisms(SNPs) mutation sites were found, g.288T>A in intron1, g. 1091 T>C, g.1096A>C, g.1770G>C in intron 2, g.2297C>T, g.2331G>A in intron3. Use ELISA to detect MBL serum level in Hu sheep, then use One-way ANOVA analyze the relationship of different genotypes and MBL serum level. And the result showed that the MBL serum level of AA genotype was higher than BB genotype (P<0.05) in intron1, CC genotype was higher than DD, GG genotype was higher than HH (P<0.05) in intron2. So, AA, CC and GG genotypes may be related to disease resistance; BB, DD and HH genotypes be related to disease susceptibility. The point mutation in intron3 couldn’t lead to the change of MBL serum level.
