description: Algae are photosynthetic eukaryotic (micro-)organisms, lacking roots, leaves, and other organs that are typical for land plants. They live in freshwater, marine, or terrestrial habitats. Together with the cyanobacteria they contribute to about half of global carbon fixation. As primary producers, they are at the basis of many food webs and they are involved in biogeochemical processes. Algae are evolutionarily distinct and are derived either by primary (e.g., green and red algae) or secondary endosymbiosis (e.g., diatoms, dinoflagellates, and brown algae). Light is a key abiotic factor needed to maintain the fitness of algae as it delivers energy for photosynthesis, regulates algal cell- and life cycles, and entrains their biological clocks. However, excess light can also be harmful, especially in the ultraviolet range. Among the variety of receptors perceiving light information, the cryptochromes originally evolved as UV-A and blue-light receptors and have been found in all studied algal genomes so far. Yet, the classification, biophysical properties, wavelength range of absorbance, and biological functions of cryptochromes are remarkably diverse among algal species, especially when compared to cryptochromes from land plants or animals.

description: For the study of complex technological processes the mathematical modeling, allowing to reduce time and expenses for research, is used. In this paper, the approaches to the mathematical modeling of electromagnetic stirring of liquid conducting medium – silicon melt, used for silicon solar cell production are investigated. The paper describes a computational method providing significant speeding up execution time of numerical calculations, based on the averaging the Lorentz force over the period of a variable magnetic field. The results of the accuracy influence of the current shape approximation in the inductors of the electromagnetic stirring system on the accuracy of the calculations for a traveling magnetic field are presented.

description: The evolution of Earth's climate over geological timescales is linked to surface erosion via weathering of silicate minerals and burial of organic carbon. However, methodological difficulties in reconstructing erosion rates through time and feedbacks among tectonics, climate, and erosion spurred an ongoing debate on mountain erosion sensitivity to tectonic and climate forcing. At the heart of this debate is the question of whether late Cenozoic climate cooling has increased global erosion rates or not. The Himalaya plays a prominent role in this debate as its erosion produces a large fraction of global sediments delivered to ocean basins. We report a 6-Myr-long record of Be10-derived erosion rates from the north-western Himalaya, which indicates that erosion rates in this region varied quasi-cyclically with a period of ∼1 Myr and increased gradually toward the present. We hypothesize that the observed pattern of erosion rates occurred in response to the tectonic growth of the Himalaya by punctuated basal and frontal accretion of rocks from the underthrusting Indian plate and concomitant changes in topography. In this scenario, basal accretion episodically changes rock-uplift patterns, which brings landscapes out of equilibrium and results in quasi-cyclic variations in erosion rates. We used numerical landscape evolution simulations to demonstrate that this hypothesis is physically plausible. We attribute the long-term increase in erosion rates to the erosional response of topography due to frequent basal accretion relative to frontal accretion. Because tectonic accretion processes are inherent to collisional orogenesis, they likely confound climatic interpretations of erosion rate histories.
Opportunities for third world industrialization : dependency theory and the newly industrializing countries
Creators: name: Iyogun, Amanele Fidelia
Publisher: name: University of British Columbia
Year: 2012

description: This study is an exploration of dependency theory and the Newly Industrializing Countries (NICs). The issues which are addressed are threefold: 1. An exploration of dependency theory, especially the variant of it that is advocated by Frank, Amin and Wallerstein. These authors have constantly maintained that growth is not possible in the Third World as long as the region is integrated into the world capitalist economy. The NICs, particularly Taiwan and South Korea are testimonies that that assumption is not entirely valid because they are incorporated and have also witnessed impressive economic growth. 2. An examination of the debate over the character of the NICs. An analysis of Taiwan and South Korea shows that they have experienced considerable economic growth. However, there is limited transformation in the standard of life of the citizens. 3. The factors that are responsible for the economic growth of Taiwan and South Korea are hypothesized. These factors are both external and internal to these countries. They are (a) a strongly polarized international ideological atmosphere which made these countries client states of the United States of America, (b) an inflow of massive aid from the U.S to these states and (c) the presence of a strong state apparatus in these countries. The state institutions combined internal creativity with the opportunities provided by the international scene to initiate and implement good strategies for their industrial transformation. The lessons other Third World countries can learn from Taiwan and South Korea is that East and West rivalry can create opportunities for strategic countries in the region of conflict. But the internal dynamics of the countries have to be responsible for seizing the chance and for utilizing it well.

description: Climate-sensitive livelihoods are in the frontline of sectors which will be affected most by climate change. Without proper intervention, smallholder farmers would suffer from declining crop production, yield, and on-farm income, among others. Hence, this study aims to assess the social vulnerability of farming households residing in northern part of Puerto Princesa City, Philippines. Sustainable Livelihoods Framework (SLF) was used in developing separate social vulnerability indices for drought, typhoon, and early onset of rains. Unbalanced weighted approach through principal component analysis (PCA) was employed in assigning weights to the variables. Findings showed that financial capital has the highest contribution to the three indices generated through PCA. Results of independent t-test statistics show that farmers are more vulnerable to typhoon and early onset of rain compared to drought. The results of the study can generate new knowledge on how to determine the social vulnerability of a community in terms of livelihood.

description: Carrots are a potentially rich source of antioxidants in addition to their nutritional properties. In this study, the nutritional composition and antioxidant properties of three varieties of carrots, namely Kuroda, Pamela and Amazonia cultivated in Ghana were determined. The peroxide scavenging method was used to determine the antioxidant properties of the ethanolic extracts of the carrot varieties at different concentrations. The protein, crude fibre, fat and carbohydrate contents of the carrot varieties ranged 6.46 – 10.73 %, 7.18 – 8.87 %, 1.97 – 4.31 % and 6.25 – 8.39 % respectively. The three varieties had high moisture contents ranging from 69.06 to 75.30 %. The antioxidant properties were high even at low concentrations of extract, and their activity increased with time in the order Amazonia > kuroda > pamela. Amazonia had the highest fibre, protein and carbohydrate contents and the lowest moisture content, making it the most preferred variety.

description: In this work, the studies on the development of 3D visualization of the multicrystalline silicon ingot structure based on digital image processing of photoluminescence of silicon wafers have been carried out. The analysis of the obtained information allows to control directional crystallization with high accuracy for obtaining multicrystalline silicon ingots with a small number of structural defects. The digital processing of photoluminescent images based on MATLAB software was used for the method research and development. Photoluminescent images of all wafers from the ingot were used as initial data. The developed method of 3D visualization of the ingot structure based on digital processing of photoluminescent silicon wafer images is used for the structure and control analysis of the ingot growing process by directional crystallization.
Flexibility and Complexity in Stationary Boundaries of Negatively Curved Groups

Publisher: name: University of Illinois at Chicago

description: The goal of this thesis is to understand the structure of the lattice of stationary boundaries, or equivalently the quotients of the Poisson boundary, for reasonable random walks on groups Γ which are flexible in a suitable sense. In particular, we will prove two main results of a similar f lavor.

1. Using the presence of actions with spectral gap we show that the (order-theoretic) lattice of stationary boundaries associated to random walks on torsion-free, (group-theoretic) lattices in SO(2,1) with an exponential moment is highly complex. Specifically, If Γ is Fn or π1(Σg) with n or g sufficiently large, and µ has an exponential moment then A The boundary lattice admits continuous deformations. B The boundary lattice contains cubes of arbitrarily high dimension.

2. Using the small cancellation theories associated to acylindrically hyperbolic groups, we show that the boundary lattice of any acylindrically hyperbolic group has an embedded copy of Cantor space, and thus has the cardinality of the continuum.

description: Nontyphoidal Salmonella (NTS) is the most reported cause of bacterial foodborne zoonoses in Vietnam, and contaminated pork is one of the main sources of human infection. In recent years, the prevalence of NTS carrying multiple antimicrobial resistance genes (ARGs) have been increased. The genomic characterization along the pig value chain and the identification of ARGs and plasmids have the potential to improve food safety by understanding the dissemination of ARGs from the farm to the table. We report an analysis of 13 S. Derby and 10 S. Rissen isolates, collected in 2013 at different stages in Vietnamese slaughterhouses and markets. VITEK 2 Compact System was used to characterize the phenotypical antimicrobial resistance of the isolates. In addition, whole-genome sequencing (WGS) was used to detect ARGs and plasmids conferring multidrug resistance. Whole genome single nucleotide polymorphism typing was used to determine the genetic diversity of the strains and the spread of ARGs along the pig value chain. Altogether, 86.9% (20/23) of the samples were resistant to at least one antibiotic. Resistance to ampicillin was most frequently detected (73.9%), followed by piperacillin and moxifloxacin (both 69.6%). At least one ARG was found in all strains, and 69.6% (16/23) were multidrug-resistant (MDR). The observed phenotype and genotype of antimicrobial resistance were not always concordant. Plasmid replicons were found in almost all strains [95.6% (22/23)], and the phylogenetic analysis detected nine clusters (S. Derby, n = 5; S. Rissen, n = 4). ARGs and plasmid content were almost identical within clusters. We found six MDR IncHI1s with identical plasmid sequence type in strains of different genetic clusters at the slaughterhouse and the market. In conclusion, high rates of multidrug resistance were observed in Salmonella strains from Vietnam in 2013. Genomic analysis revealed many resistance genes and plasmids, which have the potential to spread along the pig value chain from the slaughterhouse to the market. This study pointed out that bioinformatics analyses of WGS data are essential to detect, trace back, and control the MDR strains along the pig value chain. Further studies are necessary to assess the more recent MDR Salmonella strains spreading in Vietnam.

description: Bifacial crystalline silicon PV modules have the advantage to produce energy not only with one side, but with help of a transparent backside with both sides. A market research showed that some bifacial PV modules are not fully optimized although scientific knowledge was available before. Some experiments based on six-cell mini-module were performed to analyze the feasibility for an adaption on standard 60-cell modules. Made changings and improvements on 60-cell panels were proved with an industrial flash test system. Finally, the alignment to a commercial supporting construction and finalization of the complete test set-up on a white painted industrial roof was successful.

description: We present a Lagrangian framework for identifying mechanisms that control the isotopic composition of mid-tropospheric water vapor in the Sahel region during the West African Monsoon 2016. In this region mixing between contrasting air masses, strong convective activity, as well as surface and rain evaporation lead to high variability in the distribution of stable water isotopologues. Using backward trajectories based on high-resolution isotope-enabled model data, we obtain information not only about the source regions of Sahelian air masses, but also about the evolution of H2O and its isotopologue HDO (expressed as delta D) along the pathways of individual air parcels. We sort the full trajectory ensemble into groups with similar transport pathways and hydro-meteorological properties, such as precipitation and relative humidity, and investigate the evolution of the corresponding paired {H2O, delta D} distributions. The use of idealized process curves in the {H2O, delta D} phase space allows us to attribute isotopic changes to contributions from (a) air mass mixing, (b) Rayleigh condensation during convection, and (c) microphysical processes depleting the vapor beyond the Rayleigh prediction, i.e., partial rain evaporation in unsaturated and isotopic equilibration in saturated conditions. Different combinations of these processes along the trajectory ensembles are found to determine the final isotopic composition in the Sahelian troposphere during the monsoon. The presented Lagrangian framework is a powerful tool for interpreting tropospheric water vapor distributions. In the future, it will be applied to satellite observations of {H2O, delta D} over Africa and other regions in order to better quantify characteristics of the hydrological cycle.

description: Increasing artificial illumination during night has multifaceted effects on species. Moths are shown to be distracted and attracted by artificial light sources, leading to increased mortality through predation or exhaustion. Increased mortality can be expected to increase selection pressure on morphology, particularly those being functional in light detection and flight ability. We were thus interested if intraspecific traits differ between areas and times with differing light pollution values. We chose the moth Agrotis exclamationis, a common species in the Berlin-Brandenburg region, Germany, a region that offers very different levels of light pollution across space and time. We examined body length, eye size and forewing length, traits likely targeted through selection due to light pollution. We examined moths collected over the past 137 years. We predicted decreasing forewing length, body and eye size, in response to increasing light pollution and expected to see trait changes from the past to today, and from rural to urban areas, representing temporal and spatial gradients of increasing light pollution. In order to determine current levels of light pollution, we used radiance values of the years 2012 to 2019. These values were the base to extrapolate previous radiance values for all sample sites and years. We observed no trait differences along the spatial gradient, but trait and sex dependant changes along the temporal gradient. We could not confirm a direct causal link between changes in body size and female eye size. However, we revealed indirect effects of light pollution, and assume habitat fragmentation and host-plants to be the main drivers for these effects. A trend towards smaller-eyed females in ‘medium’ and ‘high’ light-polluted areas over time could be a first indication that morphological trait changes to light pollution are taking place.

description: We present an evaluation of the solar cell and PV module size regarding their impact on thermomechanical stress. The evaluation is based on finite element method (FEM) simulations. Within these simulations, we perform parameter variations of (i) the number of solar cells within a PV module from 60 up to 140 cells, (ii) the cell size from 156.0 mm (M1) up to 161.75 mm (M4) and (iii) the cell format from full cells down to quarter cells. The FEM simulations cover the lamination process and mechanical load of 2400 Pa and 5400 Pa for glass-foil as well as glass-glass modules. The presented results reveal correlations between the solar cell and module size with the stress in solar cells. Our investigations show that the increase of the number of solar cells within a PV module has the largest impact on the stress. However, at a mechanical load of 2400 Pa glass-foil modules with less than 96 solar cells have a negligible failure probability. The advantage of placing the solar cells in the neutral axis of the laminate is proven by the negligible tensile stress values for all variations of glass-glass modules even at 5400 Pa.

description: Parasites are important components of biodiversity and contributors to ecosystem functioning, but are often neglected in ecological studies. Most studies examine model parasite systems or single taxa, thus our understanding of community composition is lacking. Here, the seasonal and annual dynamics of parasites was quantified using a 5-year metabarcoding time-series of freshwater plankton, collected weekly. We first identified parasites in the dataset using literature searches of the taxonomic match and using sequence metadata from the National Center for Biotechnology Information (NCBI) nucleotide database. In total, 441 amplicon sequence variants (belonging to 18 phyla/clades) were classified as parasites. The four phyla/clades with the highest relative read abundance and richness were Chytridiomycota, Dinoflagellata, Oomycota and Perkinsozoa. Relative read abundance of total parasite taxa, Dinoflagellata and Perkinsozoa significantly varied with season and was highest in summer. Parasite richness varied significantly with season and year, and was generally lowest in spring. Each season had distinct parasite communities, and the difference between summer and winter communities was most pronounced. Combining DNA metabarcoding with searches of the literature and NCBI metadata allowed us to characterize parasite diversity and community dynamics and revealed the extent to which parasites contribute to the diversity of freshwater plankton communities.

description: Fluorescence signals have been widely used in information encryption for a few decades, but still suffer from limited reliability. Here, reversible multichannel fluorescent devices with encrypted information were constructed, based on two fluorescent positional isomers of a diphenylquinoxaline derivative. Possessing the same core fluorescent group and acid-/pH-responsive mechanism, the two isomers showed different fluorescence colors in an acidic environment; this allowed us to realize stepwise encryption of information in orthogonal fluorescence channels. Because the protonation was reversible, the revealed information could be re-encrypted simply by heating. This approach highlights the value of positional isomers to build multichannel encryption devices, improving their reliability on the molecular level.

description: In order to quantify the bifaciality of bifacial solar devices in a standardized way, the IEC technical specification 60904-1-2 defines two different measurement methods that can be conducted in addition to measurements at standard testing conditions. The first method (referred to as bifacial method) is based on simultaneous front and rear side illumination, the second method (referred to as equivalent irradiance (GE) method) comprises front-side illumination with increased irradiance. Intrinsic differences between the two methods can arise from the different photogeneration depth profiles for bifacial solar devices with e.g. injection-dependent recombination or inversion layer shunting. These injection-dependent effects occur as nonlinearity of short-circuit current as a function of irradiance. In this paper, the bifacial and GE methods are compared for bifacial passivated emitter and rear (PERC) solar cells with very strong nonlinearity. To detect differences between the two methods with high accuracy, an advanced measurement setup and an adapted calibration procedure have been used. The measurement uncertainties of the setup have been determined by means of Monte Carlo simulations taking into account correlations between both methods. Differences in IU parameters between the two methods were measured to be below 0.1 %rel, which is clearly within the respective measurement uncertainties. The two methods presented in the IEC technical specification 60904-1-2 can therefore be considered as consistent for bifacial solar cells with respect to nonlinearity. Further measurements and simulations indicate that the consistency also holds for lower front irradiances, which are relevant for energy rating and yield assessment of bifacial devices.

description: Single donors in semiconductor nanostructures represent a key element to develop spin related quantum functionalities in atomic scale devices. Quantum transport through a single Arsenic donor in the channel of a Silicon nano-field effect transistor under microwave irradiation is investigated. The device is characterized at mK temperatures in the regime of Coulomb-blockade. Photon assisted tunneling and microwave induced electron pumping regimes are revealed respectively at low and high microwave power. At sufficiently high power, the microwave irradiation induces tunneling through the first excited energy level of the $D_0$ energy of the donor. Such microwave assisted transport at zero bias enhances the resolution in the spectroscopy of the energy levels of the donor.

description: This work investigated the advantages of transporting charge carriers through tunnel oxide passivation contacts and realized n-type passivated contacts cell in mass production line. When the thermal silicon oxide (SiOx) tunnel layer is controlled at 1.2 nm, we presented a ~80 nm poly-silicon layer and achieved excellent passivation. The ntype doping of the poly-Si layer was achieved by POCl3 diffusion in a tube furnace, that resulted in a sheet resistance (Rsheet) of ~70Ω/sq, as measured on saw damage etched p-type monitor wafers. Excellent J0 value is down to 5.0 fA /cm2, which is measured for n+-poly-Si contacts. The front emitter is formed by BBr3 diffusion in a tube furnace at 990°C, and then driven to oxidation, resulting in a sheet resistance of Rsheet,p+ ~100 Ω/sq. The AlxO3 and SiNx layers were deposited on the front side for emitter passivation, the AlxO3 layer is about 6nm thick, performed by atomic layer deposition system. Both side silicon nitride (SiNx) antireflection coating was optimized to match the corresponding passivation and optical requirement. Finally, all of the cells were fabricated by conventional screen printing and optimized firing. The average cell efficiency achieved 22.83%, and the highest efficiency was up to 23.15%.

description: Under non-uniform operating conditions, like partial shading, several maximum power points (MPPs) may exist on the electrical characteristic of a photovoltaic (PV) array and the global MPP may vary over a wide voltage range. When multiple MPPs exist, conventional MPP tracking algorithms can be trapped to operate at a local MPP instead of the global one, and consequently the energy yield of the PV array can be considerably reduced. The partial shading of well-designed large-scale PV power plants is mainly due to shadows of moving clouds. In this article, the operation of various PV arrays at the largest MPP voltage instead of the global MPP voltage has been studied during measured irradiance transitions caused by clouds. The voltage range of the MPP with the largest voltage was found to be clearly narrower than that of the global MPP and the energy losses resulting from the operation at the largest voltage MPP instead of the global one during cloud partial shading events were found to be slight. The results of this study justify the operation of PV arrays at the MPP with the largest voltage in lieu of the global one.

description: Canada Mortgage and Housing Corporation (CMHC), the federal agency responsible for addressing the housing needs of low and moderate-income Canadians, considers those who are unable to secure physically adequate and uncrowded accommodation without spending more than 30% of their gross income to be in core housing need. This thesis analyzes single-person renter households determined to be in core housing need. Whereas the elderly (65 years and older) among core housing need singles are relatively well supported through CMHC's social housing programs, non-elderly core need singles generally do not receive support. Using an analytical framework that focusses on the severity of housing need, and by comparing the socio-economic profiles of selected age groups within this core housing need category, the study has demonstrated the existence of severe housing need, as defined by CMHC, among non-elderly core need singles and has established that the near-elderly (aged 50-64) are in the greatest need among all core need singles and are, therefore, in greater need compared to the elderly. In view of a data base upon which the allocation of assistance to at least those in the greatest need among non-elderly core need singles can be justified, it is argued that CMHC as well as other government agencies and housing support groups must acknowledge such evidence, consider a re-evaluation of priorities and take appropriate action to the extent possible in light of current fiscal restraint . Several suggestions are put forward to this end.

description: For a system composed of nine qubits, we show that natural interactions among the qubits induce the time evolution that can be regarded, at discrete times, as the Rabi oscillation of a logical qubit. Neither fine tuning of the parameters nor switching of the interactions is necessary. Although straightforward application of quantum error correction fails, we propose a protocol by which the logical Rabi oscillation is protected against all single-qubit errors. The present method thus opens a simple and realistic way of protecting the unitary time evolution against noise.

description: Temperature changes in the field (day-night changes and seasons) can affect the performance of photovoltaic modules. Standard IEC 61215 temperature cycling (TC) tests emulate this ageing typically requiring 30 to 50 days for 200 thermal cycles (degradation < 5 % is the IEC pass criterion). A faster assessment of PV modules is desirable to rapidly evaluate new interconnection technologies and module concepts. We present an accelerated TC (aTC) test that ensures the IEC required temperatures of −40 °C and +85 °C to be reached within a PV module with 200 thermal cycles performed in around 9 days, which is up to 6 times faster than standard TC. We compare results of aTC and standard IEC TC for PV modules with different interconnection technologies (five busbars, wire interconnection, and shingle interconnection by electrically conductive adhesives). IV measurements show that the degradation of the PV modules treated with aTC is quantitatively similar to that of the PV modules treated with standard IEC TC. EL images do not show differences for both tests (IEC TC and aTC). We propose that our aTC test can be used in development and for material evaluation to accelerate development times.

description: A model for mean efficiency vs. exposure time of PV-module arrays is presented, where the arrayperformance degradation is expressed as a product of functions of exposure time. Two functions expressing three sets of non-linear degradation modes reported in the literature are sufficient to fit the measured curves of efficiency vs. exposure time of an array of 20 modules and an array of 2184 modules, which were installed in 1983 and 1992, respectively, at the ENEA Casaccia research center near Roma (Italy). As a check, experimental data of efficiency vs. exposure time of a third array of 18 modules, which was installed in 1982 in Lugano (Switzerland), are also fitted with the model.

description: The relativistic four-quark equations are found in the framework of coupled-channel formalism. The dynamical mixing of the meson-meson states with the four-quark states is considered. The approximate solutions of these equations using the method based on the extraction of leading singularities of the amplitudes are obtained. The four-quark amplitudes of cryptoexotic mesons including the quarks of three flavours (u, d, s) and the charmed quark are constructed. The poles of these amplitudes determine the masses of tetraquarks. The mass values of low-lying tetraquarks are calculated.

description: We study the physical features of a class of exact solutions for cold compact anisotropic stars. The effect of pressure anisotropy on the maximum mass and surface redshift is analysed in the Vaidya-Tikekar model. It is shown that maximum compactness, redshift and mass increase in the presence of anisotropic pressures; numerical values are generated which are in agreement with observation.

description: Light trapping and reflection reduction are essential, in order to enhance the absorption of silicon solar cells. State of the art in industry is texturization using wet chemical etching of the front surface in combination with the deposition of antireflection coatings to improve the solar cell optics. Within this work an alternative route, namely a TiO2 coating with nano structures on the front side of a planar silicon solar cell encapsulated in ethylene vinyl acetate (EVA) and glass, is analyzed. The focus is put on the experimental realization of such a system. Optical measurements are compared to optical simulations using the rigorous coupled wave analysis (RCWA) and the OPTOS method. Good agreement between measurements and simulation was found, so the simulation modell can be used in the future for prediction of the optical perfomance of different structures even in a PV-module.

description: We insert the expression of Gee for internal front reflectance at Lambertian optics into an expression for sub-bandgap rear reflectance, B, obtained from the expression for sub-bandgap total reflectance of Basore. In the Basore expression, free-carrier absorption (FCA) can be included. If FCA is included, then B is calculated for intrinsic Si. If FCA is not included, then B is calculated for doped Si. We calculate curves for B vs. wavelength in two reported textures cells with Al rear reflector. In both devices, B-curves including FCA agree at sub-bandgap wavelengths with the Al-reflectance curve as calculated using the Fresnel equations.
