description: The identification of different sources of the carbonaceous aerosol (organics and black carbon) was investigated at a mountain forest site located in central Germany from September to October 2010 to characterize incoming air masses during the Hill Cap Cloud Thuringia 2010 (HCCT-2010) experiment. The near-PM1 chemical composition, as measured by a high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS), was dominated by organic aerosol (OA; 41%) followed by sulfate (19%) and nitrate (18%). Source apportionment of the OA fraction was performed using the multilinear engine (ME-2) approach, resulting in the identification of the following five factors: hydrocarbon-like OA (HOA; 3% of OA mass), biomass burning OA (BBOA; 13%), semi-volatile-like OA (SV-OOA; 19%), and two oxygenated OA (OOA) factors. The more oxidized OOA (MO-OOA, 28%) was interpreted as being influenced by aged, polluted continental air masses, whereas the less oxidized OOA (LO-OOA, 37%) was found to be more linked to aged biogenic sources. Equivalent black carbon (eBC), measured by a multi-angle absorption photometer (MAAP) represented 10% of the total particulate matter (PM). The eBC was clearly associated with HOA, BBOA, and MO-OOA factors (all together R2=0.83). Therefore, eBC's contribution to each factor was achieved using a multi-linear regression model. More than half of the eBC (52%) was associated with long-range transport (i.e., MO-OOA), whereas liquid fuel eBC (35%) and biomass burning eBC (13%) were associated with local emissions, leading to a complete apportionment of the carbonaceous aerosol. The separation between local and transported eBC was well supported by the mass size distribution of elemental carbon (EC) from Berner impactor samples. Air masses with the strongest marine influence, based on back trajectory analysis, corresponded with a low particle mass concentration (6.4-7.5 (my)g m-3) and organic fraction (~30%). However, they also had the largest contribution of primary OA (HOA ~ 4% and BBOA 15%-20%), which was associated with local emissions. Continental air masses had the highest mass concentration (11.4-12.6 (my)g m-3), and a larger fraction of oxygenated OA (~45%) indicated highly processed OA. The present results emphasize the key role played by long-range transport processes not only in the OA fraction but also in the eBC mass concentration and the importance of improving our knowledge on the identification of eBC sources. © Author(s) 202

description: The central purpose of the present thesis was to integrate the construct of autonomy support postulated by Cognitive Evaluation Theory and the literature on parental behavioral and psychological control. Its first specific objective was to demonstrate that autonomy support (AS), behavioral control (BC), and psychological control (PS) are distinct constructs. Its second specific objective was to ascertain unique associations between parental AS, BC, and PC, on one hand, and youth self-processes, internalizing symptoms, and externalized behaviors, on the other hand. Three studies were designed to achieve these goals. In Study 1A (N=342) and Study 1B (N=300), cross-sectional questionnaires were completed by undergraduate students and the dimensionality of parental behaviors was examined by means of confirmatory factor analyses. Results revealed that AS, BC, and PC are modelized in an optimal manner as distinct constructs. Study 2 ( N=138) consisted of a laboratory experiment designed to test the unique associations between AS, BC, and PC and youth self-processes, internalizing symptoms, and externalized behaviors. Study 3 (N=239) was a prospective field study that also endeavoured to examine the unique contribution of AS, BC, and PC to children functioning. In this study, self-processes, internalizing symptoms, and externalized behaviors were assessed over an 8-month competitive season. Globally, results from Study 2 and Study 3 revealed that AS predicted youth autonomous motivation, positive affect, satisfaction, and lower levels of internalizing symptoms. PC reached significant negative influences on youth functioning (i.e., controlled motivation, higher levels of impaired concentration, manifest anxiety and externalized behaviors). BC revealed positive associations with two beneficial outcome variables (i.e., autonomous motivation and lower levels of intended dropout), and a single negative consequence (i.e., manifest anxiety). Taken together, the findings of the three studies presented here provide support for the importance of distinguishing between AS, BC, and PC as basic functional dimensions that offer unique contribution to our understanding of the influence of socializing agents on youth development and functioning.

description: Here we report on observations of the radio magnetar PSRJ1622-4950 at frequencies from 1.4 to 17 GHz. We show that although its flux density is varying up to a factor of ~10 within a few days, it has on average decreased by a factor of 2 over the last 700 days. At the same time, timing analysis indicates a trend of decreasing spin-down rate over our entire data set, again of about a factor of 2 over 700 days, but also an erratic variability in the spin-down rate within this time span. Integrated pulse profiles are often close to 100percent linearly polarized, but large variations in both the profile shape and fractional polarization are regularly observed. Furthermore, the behaviour of the position angle of the linear polarization is very complex - offsets in both the absolute position angle and the phase of the position angle sweep are often seen and the occasional presence of orthogonal mode jumps further complicates the picture. However, model fitting indicates that the magnetic and rotation axes are close to aligned. Finally, a single pulse analysis has been carried out at four observing frequencies, demonstrating that the wide pulse profile is built up of narrow spikes of emission, with widths that scale inversely with observing frequency. All three of the known radio magnetars seem to have similar characteristics, with highly polarized emission, time-variable flux density and pulse profiles, and with spectral indices close to zero.

description: The Psychiatric Genomics Consortium-Posttraumatic Stress Disorder group (PGC- PTSD) combined genome-wide case–control molecular genetic data across 11 multiethnic studies to quantify PTSD heritability, to examine potential shared genetic risk with schizophrenia, bipolar disorder, and major depressive disorder and to identify risk loci for PTSD. Examining 20 730 individuals, we report a molecular genetics-based heritability estimate (h2SNP) for European- American females of 29% that is similar to h2SNP for schizophrenia and is substantially higher than h2SNP in European-American males (estimate not distinguishable from zero). We found strong evidence of overlapping genetic risk between PTSD and schizophrenia along with more modest evidence of overlap with bipolar and major depressive disorder. No single-nucleotide polymorphisms (SNPs) exceeded genome-wide significance in the transethnic (overall) meta- analysis and we do not replicate previously reported associations. Still, SNP- level summary statistics made available here afford the best-available molecular genetic index of PTSD—for both European- and African-American individuals—and can be used in polygenic risk prediction and genetic correlation studies of diverse phenotypes. Publication of summary statistics for ∼10 000 African Americans contributes to the broader goal of increased ancestral diversity in genomic data resources. In sum, the results demonstrate genetic influences on the development of PTSD, identify shared genetic risk between PTSD and other psychiatric disorders and highlight the importance of multiethnic/racial samples. As has been the case with schizophrenia and other complex genetic disorders, larger sample sizes are needed to identify specific risk loci.

description: The tendency to use Bluetooth Technology (BT) for travel time estimation is increasing due to growing number of Bluetooth-enabled devices among road users, anonymity of BT detections, flexibility of deployment and maintenance of Bluetooth sensors etc. Although Bluetooth has been demonstrated as a promising technology, there remain problems which affect the accuracy of the estimation such as difficulty of distinguishing between multiple travel modes (e.g. motor vehicles, bicycles and pedestrians). This study aims to examine the feasibility of estimating mode-specific travel time using BT data under uncongested traffic conditions. In this context, three clustering methods Hierarchical, K-means and Two-Step are used as the core techniques for classification. The results show that the methods can successfully distinguish between motor vehicles and bicycles from BT detection events, resulting in accurate travel time estimation for motor vehicles.

Selective depletion of microglial progranulin in mice is not sufficient to cause neuronal ceroid lipofuscinosis or neuroinflammation

description: Background: Progranulin deficiency due to heterozygous null mutations in the GRN gene are a common cause of familial frontotemporal lobar degeneration (FTLD), while homozygous loss-of-function GRN mutations are thought to be a rare cause of neuronal ceroid lipofuscinosis (NCL). Aged progranulin-knockout (Grn-null) mice display highly exaggerated lipofuscinosis, microgliosis, and astrogliosis, as well as mild cell loss in specific brain regions. In the brain, progranulin is predominantly expressed in neurons and microglia, and previously, we demonstrated that neuronal-specific depletion of progranulin does not recapitulate the neuropathological phenotype of Grn-null mice. In this study, we evaluated whether selective depletion of progranulin expression in myeloid-lineage cells, including microglia, causes NCL-like neuropathology or neuroinflammation in mice. Methods: We generated mice with progranulin depleted in myeloid-lineage cells by crossing mice homozygous for a floxed progranulin allele to mice expressing Cre recombinase under control of the LyzM promotor (Lyz-cKO). Results: Progranulin expression was reduced by approximately 50–70% in isolated microglia compared to WT levels. Lyz-cKO mice aged to 12 months did not display any increase in lipofuscin deposition, microgliosis, or astrogliosis in the four brain regions examined, though increases were observed for many of these measures in Grn-null animals. To evaluate the functional effect of reduced progranulin expression in isolated microglia, primary cultures were stimulated with controlled standard endotoxin and cytokine release was measured. While Grn-null microglia display a hyper-inflammatory phenotype, Lyz-cKO and WT microglia secreted similar levels of inflammatory cytokines. Conclusion: We conclude that progranulin expression from either microglia or neurons is sufficient to prevent the development of NCL-like neuropathology in mice. Furthermore, microglia that are deficient for progranulin expression but isolated from a progranulin-rich environment have a normal inflammatory profile. Our results suggest that progranulin acts, at least partly, in a non-cell autonomous manner in the brain.

description: Objectives We determined the seroprevalence and correlates of Toxoplasma gondii infection in pregnant women in Aguascalientes City, Mexico. Design A cross-sectional survey. Setting Pregnant women were enrolled in the central Mexican city of Aguascalientes. Participants We studied 338 pregnant women who attended prenatal care in 3 public health centres. Primary and secondary outcome measures Women were examined for IgG/IgM antibodies to T. gondii by using commercially available enzyme immunoassays, and an avidity test. Multiple analyses were used to determine the association of T. gondii seropositivity with the characteristics of the pregnant women. Results Of the 338 pregnant women studied, 21 (6.2%) had IgG antibodies to T. gondii, and 1 (4.8%) of them was also positive for IgM antibodies to T. gondii. Avidity of IgG antibodies to T. gondii was high in the IgM-positive sample. Logistic regression analysis of sociodemographic, behavioural and housing variables showed that T. gondii seropositivity was associated with white ethnicity (OR=149.4; 95% CI 10.8 to 2054.1; p<0.01), not washing hands before eating (OR=6.41; 95% CI 1.73 to 23.6; p=0.005) and use of latrine (OR=37.6; 95% CI 4.63 to 306.31; p=0.001). Conclusions Results demonstrate that pregnant women in Aguascalientes City have a low seroprevalence of T. gondii infection. However, this low prevalence indicates that most pregnant women are at risk for a primary infection. Factors associated with T. gondii exposure found in this study, including food hygiene, may be useful to determine preventive measures against T. gondii infection and its sequelae.

description: We report on the pulse-to-pulse energy distributions and phase-resolved modulation properties for catalogued pulsars in the southern High Time Resolution Universe intermediate-latitude survey. We selected the 315 pulsars detected in a single-pulse search of this survey, allowing a large sample unbiased regarding any rotational parameters of neutron stars. We found that the energy distribution of many pulsars is well described by a log-normal distribution, with few deviating from a small range in log-normal scale and location parameters. Some pulsars exhibited multiple energy states corresponding to mode changes, and implying that some observed 'nulling' may actually be a mode-change effect. PSRJ1900-2600 was found to emit weakly in its previously identified 'null' state. We found evidence for another state-change effect in two pulsars, which show bimodality in their nulling time-scales; that is, they switch between a continuous-emission state and a single-pulse-emitting state. Large modulation occurs in many pulsars across the full integrated profile, with increased sporadic bursts at leading and trailing sub-beam edges. Some of these high-energy outbursts may indicate the presence of 'giant pulse' phenomena. We found no correlation with modulation and pulsar period, age or other parameters. Finally, the deviation of integrated pulse energy from its average value was generally quite small, despite the significant phase-resolved modulation in some pulsars; we interpret this as tenuous evidence of energy regulation between distinct pulsar sub-beams.

description: Nøjagtig estimering af køretider er relevant for en lang række transportvirksomheder for at udnytte køretøjerne bedst muligt. I denne artikel beskrives det, hvorledes de store mængder lavfrekvent GPS data, der allerede opsamles kan anvendes til at højne nøjagtigheden af de estimerede køretider. Til dette formål anvendes OpenStreetMap, som er et digitalt kort, der omkostningsfrit kan distribueres. Artiklen lister detaljerne for hvor map-matchingen er implementeret. Resultaterne viser, at det er væsentligt at tage kørselsretningen med i betragtning når køretider skal estimeres. Dette er specielt vigtigt i centrum af de større byer, hvor der kan være 20-40 % forskel i køretiderne på den samme strækning i forskellig retning.

description: This article explains the emission consequences of using biodiesel and bio ethanol as a fuel for road transport in Denmark calculated in the REBECa project. For the years 2004, 2010, 2015, 2020, 2025 and 2030, two fossil fuel baseline scenarios (FS) are considered characterised by different traffic growth rates. For each FS, two biofuel scenarios (BS1, BS2) are considered with a 5.75 % biodiesel/bio ethanol share in 2010 as a common starting point. From 2010, linear growths are assumed for BS1 (10 % in 2020) and BS2 (25 % in 2030). The emissions presented in this study are vehicle based; a separate Well to Wheels (W-t-W) assessment of the total emission consequences of producing and using biofuels has been conducted in a different part of REBECa. The maximum CO2 emission difference between FS and BS2 becomes 26 % in 2030. The NOx and VOC emission variations between FS and both biofuel scenarios are 3 % or less. For CO and TSP the largest emission differences, 5 % and -12 %, respectively, occur between the FS and BS2 scenarios in 2030. The biofuel emission impacts are insignificant for NOx,VOC, CO and TSP compared to the generally large emission reductions predicted in all scenarios driven by the gradual strengthened emission standards for new vehicles, by far outweighing the emission influence from biofuels and traffic growth. The emission estimates for NOx, VOC, CO and TSP presented in this study are less certain than for CO2 due to the relatively scarce biofuel emission data implemented in the calculations. As a consequence, the obtained emission results must be assessed with care. Bearing in mind these uncertainties, the calculation approach for emissions from biofuel usage presented in this study can be used as a tool to carry out sensitivity analysis, environmental impact assessment studies, or for research purposes as such.

The roles of the carboxyl-terminal regions of phospholipid transfer protein (PLTP) and cholesteryl ester transfer protein (CETP) in lipid transfer.

description: In human plasma, there are two lipid transfer proteins that play major roles in lipoprotein metabolism and reverse cholesterol transport. Cholesterol ester transfer protein (CETP) transfers neutral lipids, and is responsible for all of the plasma cholesteryl ester (CE) and triglyceride (TG) transfer activity. Both CETP and phosopholipid transfer protein (PLTP) can facilitate the exchange of phospholipid (PL) among lipoproteins, but only PLTP mediates net mass PL transfer. Residues at the carboxy termini of CETP and PUP have been shown to be essential for protein function. In order to examine the roles of the C-termini of CETP and PUP in determining lipid specificity, we have expressed and characterized chimeric proteins in which the C-termini of PUP and CETP are exchanged. The chimeras CETP1--460/PLTP 445--476 (CP), CETP1--460/PLTP445--476 -mycHIS (CP-HIS), and PLTP1--444/CETP461--476 (PC) were secreted from COS-7 cells, indicating that the overall fold of the proteins was not disturbed. The proteins CP, CPHIS, and PC each had less than 10% of the CE and TG transfer activities of CETP. The proteins CP and CPHIS each had less than 10% of the PLTP-specific PL transfer activity of PUP. These results suggest that the carboxy-termini of CETP and PLTP act in concert with other parts of the molecule to facilitate lipid transfer. Another goal of this research was to produce and characterize a panel of monoclonal antibodies (mAbs) to human PLTP. Attempts to produce mAbs in mice using protein immunization were unsuccessful, but PLTP-specific antibodies were detected in serum from mice immunized with plasmid DNA encoding the human PLTP sequence.

description: Background Few studies have investigated physical activity (PA) and sedentary behavior (SB) in relation to fasting (FG) and 2-h postprandial plasma glucose (2hPG) levels and gestational diabetes mellitus (GDM); we investigated these associations among Asian pregnant women. Methods As part of the Growing Up in Singapore Towards healthy Outcomes cohort study, PA and SB (sitting and television times) were assessed by interviewer-administered questionnaire. During 75 g oral glucose tolerance tests at 26–28 weeks’ gestation we measured FG, 2hPG levels and GDM (FG ≥ 7.0 mmol/L and/or 2hPG ≥ 7.8 mmol/L). Associations were analysed by multiple linear and logistic regression. Results Among the 1083 women studied, 18.6% had GDM. SB was not associated with FG, 2hPG and GDM. Higher categories of PA were associated with lower 2hPG and a lower likelihood of GDM (p-trend < 0.05), but not with FG levels. Compared to insufficiently active women, highly active women had lower 2hPG levels [β (95% CI): -0.32 (−0.59, −0.05), p = 0.020) and were less likely to have GDM [OR: 0.56 (0.32–0.98), p = 0.040]. Stratified analysis revealed no associations among under/normal-weight women, but significant associations among overweight/obese women; in those with BMI ≥23 kg/m2, sufficiently active and highly active women were less likely to have GDM [OR: 0.52, (0.29–0.93), p = 0.028, and OR: 0.34, (0.15–0.77), p = 0.010, respectively]. Conclusion Higher PA was associated with lower 2hPG levels and a lower prevalence of GDM, particularly in overweight/obese women. Further studies are warranted to confirm these findings, and to examine the effectiveness of PA promotion strategies for the prevention of gestational hyperglycemia.
Bilers brændstofforbrug og CO2 udledning

Year: 2012

description: Transporten er den næststørste udleder af drivhusgasser i EU, og sektorens emissioner er stigende. Vejtransporten står for mere end 70 procent, og af denne står person- og varebiler for cirka 2/3 af emissionerne. I takt med at det blev klart at fællesskabets hidtidige strategi for nedbringelse af nye personbilers CO2 udledning til 120 g CO2/km ikke ville blive opfyldt i 2012, har Kommissionen indført bindende krav til industrien – først for personbiler og senest også for varebiler. Indsatsens påvirkning af udviklingen for nye personbiler er nu begyndt at tone frem, og målet for 2012 vil blive mødt. Målene for 2020 er i øjeblikket ved at blive endeligt fastlagt.

description: We present 75 pulsars discovered in the mid-latitude portion of the High Time Resolution Universe survey, 54 of which have full timing solutions. All the pulsars have spin periods greater than 100ms, and none of those with timing solutions is in binaries. Two display particularly interesting behaviour; PSR J1054-5944 is found to be an intermittent pulsar, and PSR J1809-0119 has glitched twice since its discovery. In the second half of the paper we discuss the development and application of an artificial neural network in the data-processing pipeline for the survey. We discuss the tests that were used to generate scores and find that our neural network was able to reject over 99per cent of the candidates produced in the data processing, and able to blindly detect 85per cent of pulsars. We suggest that improvements to the accuracy should be possible if further care is taken when training an artificial neural network; for example, ensuring that a representative sample of the pulsar population is used during the training process, or the use of different artificial neural networks for the detection of different types of pulsars.
Broadband indoor wireless communications using infrared.

Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis, we discuss the issue of using infrared light as a carrier for broadband indoor wireless networks. We discuss the infrared channel and show how it differs from conventional radio frequency channel. Noise sources for this environment and the practical ways of reducing their harmful effects are discussed. We determine the safety levels for the radiated power of an IR transmitter and we show how the system should be designed to operate within the safety limits. We introduce a computer-simulation algorithm to find the impulse response of an indoor infrared channel and discuss several implementation issues for the algorithm. Using the simulation software, we investigate temporal and spatial distributions of the channel, e.g., the delay spread of impulse response and the total received optical power. We use the results of the simulations to investigate the effects of receiver rotation on the channel properties. We propose an angular diversity as a mean for performance improvement in an infrared receiver. Simulating the noise sources and signal sources in a typical indoor environment, we see how diversity improves the signal-to-noise ratio in a receiver with the angular diversity reception.

description: An international online database was launched in 2009 by the Mobile Manufacturers Forum on accessibility features on mobile phones for people with disabilities (AMTA 2009). This was a direct result of the development of an Australian Industry Code about information on accessibility features for telephone equipment. This paper outlines the need for phone accessibility information by consumers and describes the complex processes that led to this new service. It examines the code development process and its difficulties. It is an example of the need to consider changing the self-regulatory model to better benefit consumers with disabilities.

Subjects: subject: Engineering, Electronics and Electrical.

description: Speech communications over ATM networks is one of the important issues in the broadband ISDN. Although CCITT Study Group XIII has already proposed the Draft Recommendation I.121 on speech communications over broadband ISDN, there are many open issued to be further studied before the effective deployment of speech communications over broadband ISDN can take place. In this thesis, several issues on speech transmission over ATM network have been studied, such as packetization delay, network queuing delay, digital speech encoding algorithms and PVR algorithm. A packetized speech emulation device is proposed to provide the capability of subjective speech transmission quality evaluation over ATM network or other kind of packetized network. The boundary of speech transmission quality degradation that human hearing can tolerate against information loss rate, delay fluctuation and encoding mechanism are found through emulation. The echo effect in ATM network, which is a primary issue in speech communications is also discussed in the thesis. In particular, the emphasis is given to the specification, design and implementation of ATM speech emulator which consists of two subsystems: ATM Network Simulator (ATMNS) and Speech Transmission Emulator (STE). ATMNS has been specified according to the results of ATM network performance analysis, and STE is based on ATM specifications recommended by CCITT. A prototype of the emulator has been implemented on a personal computer and DSP5600 development system with a special designed audio interface to interconnect phone sets to the DSP5600 AD input. The software had been written in "C" and DSP assembly language. Subjective evaluation are conducted in terms of the following factors: Cell discarding rate, different network queuing delay and fluctuation to different PVR algorithms. These factors are basic issues which may affect ATM speech transmission quality in an ATM network. Finally, test results under different network conditions are given.
