Abstract:
For the past twenty years, there has been increasing interest and investment in solar photovoltaic (PV) technology. One particular area of interest is the development of concentrating PV (CPV), especially for use in building integration. Many CPV designs have been developed and investigated. This paper aims at producing a mathematical modelling using MATLAB programme to predict the current-voltage (I-V) and power-voltage (P-V) characteristics of a static CPV. The MATLAB programme could also simulate the angular response of the CPV designs-which has never been explored in the previous literature. In this paper, a CPV known as the rotationally asymmetrical dielectric totally internally reflecting concentrator (RADTIRC) was analysed. A specific RADTIRC design that has an acceptance angle of ±40° was investigated in this paper. A mathematical modelling was used to simulate the angular characteristics of the RADTIRC from −50° to 50° with an increment 5°. For any CPV, we propose that the value of opto-electronic gain, Copto-e needs to be included in the mathematical model, which were obtained from experiments. The range of incident angle (±50°) was selected to demonstrate that the RADTIRC is capable of capturing the sun rays within its acceptance angle of ±40°. In each simulation, the I-V and P-V characteristics were produced, and the short circuit current (Isc), the open-circuit voltage (Voc), the maximum power (Pmax), the fill factor (FF) and the opto-electronic gain (Copto-e) were determined and recorded. The results from the simulations were validated via experiments. It was found that the simulation model is able to predict the I-V and P-V characteristics of the RADTIRC as well as its angular response, with the highest error recorded for the Isc, Voc, Pmax, FF and Copto-e was 2.1229%, 5.3913%, 9.9681%, 4.4231% and 0.0000% respectively when compared with the experiment.

Abstract:
Ultrasound elastography is a technique used for clinical imaging of tissue stiffness with a conventional ultrasound machine. It was first proposed two decades ago, but active research continues in this area to the present day. Numerous clinical applications have been investigated, mostly related to cancer imaging, and though these have yet to prove conclusive, the technique has seen increasing commercial and clinical interest. This paper presents a review of the most widely adopted, non-quantitative, techniques focusing on technical innovations rather than clinical applications. The review is not intended to be exhaustive, concentrating instead on placing the various techniques in context according to the authors' perspective of the field.

Abstract:
This essay addresses the common goals of but also the practical differences between the emerging fields of Performance Philosophy (PP) and Practice as Research (PaR). It does so by describing them both as interposing effective and affective action into the process of thinking and knowing, thereby resisting what Gilles Deleuze calls the Dogmatic Image of Thought. The dogmatic image is described as a directional movement based on Plato’s allegory of the cave, where those who would learn turn away from phenomenal becoming and move upward and outward towards eternal Truth. This movement travels from a static unknowing to a static knowledge. Both PP and PaR resist such movement by employing techniques which forestall arriving at either stasis. Through their developments, PP and PaR have come to concentrate on resisting one of these points of stasis or the other – with PP concentrating on avoiding static knowing, and PaR concentrating on finding the proper expression to avoid static unknowing, even while presenting its findings in forms that may appear ephemeral.

Abstract:
Solar energy has demonstrated promising prospects in satisfying energy requirements, specifically through solar photovoltaic (PV) technology. Despite that, the cost of installation is deemed as the main hurdle to the widespread uptake of solar PV systems due to the use of expensive PV material in the module. At this point, we argue that a reduction in PV cost could be achieved through the usage of concentrator. A solar concentrator is a type of lens that is capable of increasing the collection of sun rays and focusing them onto a lesser PV area. The cost of the solar module could then be reduced on the assumption that the cost of introducing the solar concentrator in the solar module design is much lower than the cost of the removed PV material. Static concentrators, in particular, have great promise due to their ability to be integrated at any place of the building, usually on the building facade, windows and roof, due to their low geometrical concentration. This paper provides a historic context on the development of solar concentrators and showcases the latest technological development in static PV concentrators including non-imaging compound parabolic concentrator, V-trough, luminescent solar concentrator and quantum dot concentrator. We anticipated that the static low concentrating PV (LCPV) system could serve to enhance the penetration of PV technology in the long run to achieve the Sustainable Development Goal (SDG) 7—to open an avenue to affordable, reliable, sustainable, and modern energy for all by 2030.

Abstract:
A solar concentrating system incorporated to the south-facing wall could be a promising solution to alleviate the energy demand pressure in buildings. However, concentrating systems incorporated in south-facing walls would require wide acceptance range of concentrators with the purpose of static installation. In order to tackle this problem, this article proposes a novel unitary asymmetric concentrator structure for incorporating the concentrating system in the south-facing wall. A general optimization strategy for the annual performance enhancement of the concentrator is reported. Four kinds of concentrators were designed based on the proposed structure. The annual performance enhancement by this optimization strategy was analysed and compared through the ray-tracing simulation and experimental validation for four typical types of solar concentrators, i.e. Mirror Concentrator, Lens-Mirror Concentrator, Dielectric Concentrator and Air-Gap-Lens-Mirror Concentrator. The optical performance of these concentrators was studied and compared. Their application was analysed and validated through the analysis. The findings have illustrated the optical efficiency of the concentrators for concentrating the photovoltaics or photovoltaic-thermal system incorporated to the south-facing wall either by attachment or embedded into a building structure like a window. These concentrators can be engineered as the main component as a part of the design for a building.

Abstract:
The processing of Mexican limes generates great amounts of peel as a by-product. Lime peel is mainly rich in the flavonoid hesperidin, whose bioactivity is oriented mainly to cardiovascular diseases and cancer. The purpose of this work was to develop a green process for the extraction and purification of hesperidin from Mexican lime peel. The extraction of hesperidin was investigated on a laboratory scale by varying the solvent composition and the solid-to-solvent ratio, and then scaling this process (volume: 20 L). Next, a purification process using adsorption resins was assessed: first through static tests to determine the adsorption efficiency with two resins (FPX66, EXA118), and then on a packed column with 80 mL of resin at 25 °C. Lab-scale extraction showed that the best conditions were a solid-to-solvent ratio of 0.33 g/mL and 60% ethanol. After using these conditions at pilot scale and concentrating the solution, the hesperidin content of the extract was 0.303 mg/mL. Through static tests, higher adsorption efficiencies were achieved with the EXA-118 resin and diluted extract (4:6 ratio with 10% dimethylsulfoxide, (DMSO)). Finally, the purification process on a packed column from the diluted extract (hesperidin concentration of 0.109 mg/mL) had a mean recovery efficiency of almost 90%.

Abstract:
Currently the quantitative description of confinement inside nuclear matter is exclusively limited to computer experiments, mainly on lattices, and concentrating upon calculating the static potential. There is no independent reference for comparison and support of the results, especially when it comes to the quark potential in the continuum limit. Yet, we are entitled to be optimistic, for the basic results of these calculations seem to be correct from an entirely different point of view, suggested by Manton's geometrization of Skyrme theory. The present work shows the reasons of this point of view, and offers a static potential that might serve as independent reference for comparison and endorsement of any lattice calculations, and in fact of any structural hypotheses of nuclear matter. A historical review of the pertinent key moments in the history of modeling of nuclear matter, as well as an outlook anticipating the necessary future work, close the argument.

Abstract:
The aim of this document is to investigate through industrial design the potential of a high efficiency photovoltaic concentrator theory. The investigation directs a proposed layout for the design of a device, which specifically addresses the incorporation of the concentrator theory into the design of a photovoltaic ????????roof tile????????. The focus of the investigation has been the integration of theoretical constructs and physical realities. The objective is to facilitate this transition from theory to reality: to contribute to the quest of creating viable manufacturable designs for the generation of clean low cost electrical power. The use of a roof tile as the focus of the incorporating device served two purposes. Number one: it provided a sensible, existing platform, which is under utilised, presented potential and fitted within established building practices. It was not the objective of this thesis to argue that tile integration is the best, only or even the most financially viable direction to pursue; it was one option among many. This brings us to the second purpose; the consideration of existing roofing tiles forced the theory to be applied within set limitations, in particular existing size restrictions. The imposition of a framework to work within highlighted the design issues, which would have to be addressed in the actualisation of the theory. The theory????????s broad strategy for economic viability has been to reduce the actual silicone cell content of panel designs by approximately one third. This is achieved by the use of numerically fewer cells in combination with a concentration method, which does not cost more than the savings gained by the use of fewer cells. This document records the design process undertaken and presents the findings so that further development can be undertaken.

Abstract:
During production of different Hyaluronic acid (HA) products Galderma use a high concentration of NaOH in the crosslinking process of HA. HA’s degradation kinetics are widely unknown at higher pH’s and is interesting for the future of product development of HA. Static Light Scattering (SLS) was used to determine the weight average molecular weight (MW ) of samples with four different NaOH concentrations, four temperatures, three reaction times and one t0  sample. The results were evaluated in forms of Arrhenius-graphs for different NaOH concentrations, the activation energy (EA ) with respect to pH and the reaction rate for each temperature with respect to NaOH concentration. It was found that the degradation of HA was more strongly affected by temperature than by NaOH concentration and that the EA  did not show any significant signs of change between higher concentrations of NaOH.

Abstract:
This study examines the congressional mission to liberated concentration camps in April and May 1945. General Dwight D. Eisenhower requested a congressional mission and a group of newspaper editors and publishers to view firsthand the horrors of the concentration camp Buchenwald, so that the American public might be made more aware of German atrocities in concentration camps and to dispel the belief that the atrocity reports were wartime propaganda. The congressmen and newspapermen were horrified by what they saw at the German concentration camps, and many reported back to the American public about the atrocities and conditions in the concentration camps through articles, interviews, speeches, and rallies. Upon their return to the United States, the congressmen published a report on the conditions within the camps, and many of them spoke in Congress and to the public about the need to re-educate the Germans, try guilty Germans, and rebuild Germany. The congressmen and editors and publishers brought legitimacy to the reports of American war correspondents concerning German atrocities, and their efforts contributed to constructing a political climate that allowed for and legitimized the Nuremberg Trials, the U.S. Army denazification efforts, and the rebuilding of Germany through the Marshall Plan. To examine this mission, newspaper articles from April and May 1945 were collected from thirteen American newspapers, as well as the Times of London. Research was also conducted in the personal collections of two of the congressmen who toured Europe at that time, as well as at the National Archives in College Park, MD. This study goes beyond the existing research by examining the congressional mission to Buchenwald, Dora, and Dachau, which, though it has been briefly mentioned in existing Holocaust literature, has never been fully examined.

Abstract:
Recent, post-1980, immigration patterns have had a dramatic effect on U.S. labor markets, leading to considerable debate about the impact of immigration on native-born black workers. This research examines immigrant and black labor markets, across metropolitan areas, using Public Use Microdata and Summary File data from Census 2000 to generate low, mid, and high classifications of immigrant and black occupations based on socio-economic index (SEI). Multivariate findings indicate that the effect of recent immigration on black labor market outcomes differs by occupational level. Competition for low-skilled jobs is identified for native-born blacks in low-level jobs while a “bump-up” effect is identified for blacks in mid-level jobs. For example, production occupations with low language and skill requirements are shown to be contested among the groups. On the other hand, service and administrative functions emerge as bump-up mechanisms that create opportunity for black workers who amass the human capital required of these occupations. Thus, the ramifications of immigration for native-born blacks are shown to be quite different for low- and mid-SEI jobs.

AbstractThis chapter focuses on the evaluation of air quality and health impacts associated with direct emissions of air pollutants for different REFLEX scenarios based on the Driver-Pressure-State-Impact-Response framework. Ambient concentration of air pollutants is calculated with the use of the Polyphemus Air Quality System. Health impacts are calculated using the concentration-response functions. Results show that particulate matter emissions in Europe will decrease by 10 times till 2050. Also ambient pollutants concentrations decrease in 2050 in all REFLEX scenarios. This leads to the reduction of external costs of almost 20 billion EUR per year.

Abstract:
AbstractSeveral methods exist for evaluating plant nutritional status. Looking for visual deficiency symptoms is perhaps the simplest approach, but once symptoms appear, crop performance has already been compromised. Several other techniques have been developed. All of them require correlation studies to provide plant performance interpretations. Reflectance is a remote sensing technique that detects changes in light energy reflected by plant tissue. It has proven successful in detecting nutrient deficiencies but does not yet have the ability to discriminate among more than one deficiency. Chemical assays of leaf tissue, known as tissue tests, require destructive sampling but are the standard against which other assessments are compared. Sufficiency ranges provide concentrations of each nutrient that are considered adequate for crop growth and development. They consider nutrients in isolation. Other approaches have been developed to consider how the concentration of one nutrient in tissue impacts the concentrations of other nutrients. These approaches strive to develop guidelines for maintaining nutrient balance within the plant. All approaches require large data sets for interpretation.

Abstract:
Accurate and reliable models are necessary to predict the performance and efficiencies of concentrating solar power plant components and systems such as heliostats and central receiver systems. Heliostat performance is impacted from effects such as wind and gravity, and understanding the impact of these loads on the optical performance can yield heliostat designs that are potentially cheaper, while maintaining required structural stability. Finite element models of heliostats at the National Solar Thermal Test Facility (NSTTF) at Sandia National Laboratories in Albuquerque, NM, were developed to simulate displacements under different loading scenarios. Solidworks was used to develop the three-dimensional model of the NSTTF heliostat, and Solidworks Simulation was used to perform the finite element analysis with simulated loads along different points of the heliostat. Static displacement tests were performed on the NSTTF heliostat in order to validate these FEA models. The static test results provide us with a data set in which to properly calibrate the FEA model to better represent the NSTTF heliostat for future simulations of optical performance with impacts of wind and gravity sag. In addition to a single model validation, this real world test provides a method to validate and understand the structural stability of a heliostat under static loads.

Abstract:
Several approaches for the precision control of micro-scale positioning mechanisms, or MEMS nanopositioners, are presented along with initial experimental results which demonstrate nano-scale positioning resolution. The MEMS nanopositioners discussed in this paper are novel precision mechanisms comprised of a bent-beam thermal actuator and a flexure mechanism for each degree of freedom (DOF). These mechanisms can be used for a host of ultra-precision positioning applications, including nanomanipulation, scanning probe microscopy, high-density data storage and beam steering arrays. Concentrating on a 1 DOF MEMS nanopositioner, empirical static and dynamic models have been derived using characterization data obtained from experiments with optical and laser probe microscopes. Based on these models, three control approaches have been developed: 1) a quasi-static nonlinear open-loop controller, 2) a nonlinear forward compensator, and 3) a nonlinear PI controller. Simulation and initial experimental results are presented, and the benefits of each of these approaches are discussed.

Abstract:
Abstract The MinWaterCSP project was defined with the aim of reducing the cooling system water consumption and auxiliary power consumption of concentrating solar power (CSP) plants. A full-scale, 24 ft (7.315 m) diameter model of the M-fan was subsequently installed in the Min WaterCSP cooling system test facility, located at Stellenbosch University. The test facility was equipped with an in-line torque arm and speed transducer to measure the power transferred to the fan rotor, as well as a set of rotating vane anemometers upstream of the fan rotor to measure the air volume flow rate passing through the fan. The measured results were compared to those obtained on the 1.542 m diameter ISO 5801 test facility using the fan scaling laws. The comparison showed that the fan power values correlated within +/− 7% to those of the small-scale fan, but at a 1° higher blade setting angle for the full-scale fan. To correlate the expected fan static pressure rise, a CFD analysis of the 24 ft (7.315 m) diameter fan installation was performed. The predicted fan static pressure rise values from the CFD analysis were compared to those measured on the 1.542 m ISO test facility, for the same fan. The simulation made use of an actuator disc model to represent the effect of the fan. The results showed that the predicted results for fan static pressure rise of the installed 24 ft (7.315 m) diameter fan correlated closely (smaller than 1% difference) to those of the 1.542 m diameter fan at its design flowrate but, once again, at approximately 1° higher blade setting angle.

Abstract:
A number of sites around the United States have used activated carbon (AC) amendments to remedy contaminated sediments. Variation in site-specific characteristics likely influences the long-term fate and efficacy of AC treatment. The long-term effectiveness of an AC amendment to sediment is largely unknown, as the field performance has not been monitored for more than three years. As a consequence, the focus of this research effort was to evaluate AC’s long-term (6–10 yr) performance. These assessments were performed at two pilot-scale demonstration sites, Grasse River, Massena, New York and Canal Creek, Aberdeen Proving Ground (APG), Aberdeen, Maryland, representing two distinct physical environments. Sediment core samples were collected after 6 and 10 years of remedy implementation at APG and Grasse River, respectively. Core samples were collected and sectioned to determine the current vertical distribution and persistence of AC in the field. The concentration profile of polychlorinated biphenyls (PCBs) in sediment pore water with depth was measured using passive sampling. Sediment samples from the untreated and AC-treated zones were also assessed for bioaccumulation in benthic organisms. The data collected enabled comparison of AC distribution, PCB concentrations, and bioaccumulation measured over the short- and long-term (months to years).
