Impact of Strain-Actuated Attitude Control Systems for Variant Mission Classes

The University of Illinois, in collaboration with NASA Jet Propulsion Laboratory (JPL) and NASA Ames Research Center, has developed a novel Attitude Control System (ACS) called the Strain Actuated Solar Arrays (SASA), with sub-milli-arcsecond pointing capability. SASA uses strain-producing actuators to deform flexible deployable structures, and the resulting reaction forces rotate the satellite. This momentum transfer strategy is used for jitter reduction and small-angle slew maneuvers. The system is currently at a Technology Readiness Level of 4-5 and has an upcoming demonstration flight on the CAPSat CubeSat mission. An extension to the SASA concept, known as Multifunctional Structures for Attitude Control (MSAC), enables arbitrarily large-angle slew maneuvers in addition to jitter cancellation. MSAC can potentially replace reaction wheels and control moment gyroscopes for attitude control systems, thereby eliminating a key source of jitter noise. Both SASA and MSAC are more reliable because of fewer failure modes and lower failure rates as compared to conventional ACS, while having an overall smaller mass, volume, and power budget. The paper discusses the advantages of using SASA and MSAC for a wide range of spacecraft and variant mission classes.
Heritability of time preference: Evidence from German twin data

Intergenerational correlations of time preference are well documented. However, there is still limited empirical evidence about the role of genetics in this transmission process. In our paper, we use data on roughly 3,000 twins from the German TwinLife project to estimate the heritability of time preference. We rely on an experimentally validated survey measure of temporal discounting, namely, self-assessed patience. The analysis of monozygotic and dizygotic twins enables us to apply standard biometric models. We find that genetic differences explain up to 23 percent of individual variation in patience. Whereas the additive genetic effect and common environmental effects are of minor importance, a major dominant genetic effect is present. These results indicate a notable degree of genetic influence on economic time preferences.
Stromatolite research in the Shark Bay World Heritage Area

Three decades after declaration of World Heritage status for Shark Bay new research findings are being reported on the specialised microbial habitats that characterise its hypersaline settings, the composition of microbial communities, tidal flat evolution, stromatolite geochronology and subtidal microbial systems. In the stable, semiarid and evaporative setting within the intertidal–subtidal environment the microbial ecosystem is trapping, binding and biologically inducing carbonate precipitation within laminated stromatolites, non-laminated thrombolitic forms and cryptomicrobial non-laminated forms. Filamentous microbes constitute the dominant group in the blister, tufted and smooth mat types, and coccoid microbes dominate the pustular, colloform and microbial pavement deposit types. Detailed georeferenced substrate mapping has revealed extensive subtidal microbial deposits occupying ~300 km of the total Holocene 1400 km area of Hamelin Pool. The microbial pavement covers 227 km of the subtidal substrate, which together with columnar structures reveals a subtidal microbial habitat that occupies an area several times larger than the area of the intertidal deposits. Oldest dated stromatolite heads are 1915 C years BP, and the overall system was deposited in two stages: the first between 2000 and 1200 and the last from 900 years BP to the present. Slow accretion rates vary from less than 0.1 to 0.5 mm/year. Different internal fabrics were constructed according to their position in relation to the littoral zone by distinct microbial communities, and lateral fabric relations have been established. Evidence of shallowing-upward fabric sequences of microbial origin reflects relative falling sea levels during the late Holocene and is likely useful in ancient environmental interpretation. A new substrate map and depositional history for this distinctive microbial habitat has established the significance of subtidal structures and emphasises the geoscientific importance of Hamelin Pool, especially with respect to early life studies and ancient analogues for understanding microbial activity, deposit characteristics, fenestral fabrics and distribution.
The Case of the Philippines

This paper investigates how the two types of globalization—i.e., integration of international trade and emigration—affected poverty reduction in the Philippines. Using the Family Income and Expenditure Surveys from 1985 to 2000, we found that both nontransfer and transfer incomes decreased poverty significantly but transfer income exerted greater impact. External openness reduced poverty significantly before the Asian currency crises but its impact had been reversed since. The effect of land reform in inducing transfer income from abroad was significant only in the 1990s. Yet, the ultra poor were bypassed in the land reform-credit-emigration-transfer nexus.
SURFACE PROPERTIES OF BEECH WOOD MODIFIED BY CO2 LASER

The paper is focused on the analysis of surface properties of beech wood modified by the CO2 laser. Colour and morphological changes in the beech wood surface subjected to laser treatment under different irradiation doses were monitored. Experiments were carried out to investigate the wetting surfaces treated with standard liquids. Free surface energy values were also determined for these surfaces. The results showed that increasing the irradiation dose over a range of 075 J∙cm2 induced a significant increase in the total colour difference (E = 45). This discolouration was caused by a significant decrease in brightness L from 73 to 30 and also by the decreased colour coordinates a a b. Significant morphological changes were not detected except at the highest irradiation dose with the entire surface layer being carbonised and the surface roughness increased. An increase in irradiation doses resulted in a decrease in the surface free energy values of beech wood. However, the wood surface modified this way still complied with the requirements for surface treatment with coating materials and for gluing.
Convergence Acceleration of the Harmonic Balance Method Using a Time-Level Preconditioner

The Harmonic Balance method is nowadays widely applied for numerically solving problems that are known to possess time-periodic solutions. Key reasons for its success are its wide range of applicability, relative ease of implementation, and computational efficiency compared to time-accurate approaches. The computational efficiency of the Harmonic Balance method is partly derived from the fact that it searches directly for a periodic solution, instead of integrating the governing equations in time until a periodic solution is reached. Convergence acceleration techniques such as multigrid, implicit residual smoothing and local time stepping may also be used to improve the efficiency of the Harmonic Balance method. This paper considers another option for accelerating convergence, namely a novel time-level preconditioner that can be applied to the Harmonic Balance residual locally in each computational cell. This preconditioner is derived from a rigorous stability analysis of the Harmonic Balance equations and is shown to give a speed-up factor of 2 when applied to simulations of laminar vortex shedding behind a circular cylinder.
Progress in Organic Coatings

A unique, non-leaching and durable novel anti-biocide polyacrylamide-starch coating (pAam-g-S) has successfully been synthesized. In this study, a grafted cationic-functionalized polymeric coating was designed and cross-linked with native starch extracted from Dioscorea hispida sp. yam to afford multifunctional anti-fungal and anti-termite coating. Leaching of the disinfectant into the environment was eliminated because no toxic chemicals were used. The copolymerization was successfully carried out to produce various ratios of pAam-g-S coating using modification of starch-gel. Results obtained from Fourier Transform Infrared-Attenuated Total Reflectance (FTIR-ATR) confirmed the monomer pAam was grafted onto the starch backbone as shown by the cross-linked peak at 1642 cm−1. Supported by differential scanning calorimetry (DSC), the highest transition glass temperature was observed at 154 ◦C. The coating was designed to continuously decontaminate against pathogenic fungus and termite in addition to afford preliminary anti-biocides properties. Facile anti-fungal and anti-termite evaluations were conducted via total weight loss of wood (%) studies using white rot fungus, Pycnoporus. sanguineus and termite Coptotermes curvignathus respectively. In order to verify the coating performance, gel fractions, morphologies and heat resistant properties were also investigated. © 2016 Elsevier B.V. All rights reserved.
Shaken vs scraped: floral presentation contributes to pollinator guild segregation in co-blooming Symphionema montanum and Isopogon anemonifolius (Proteaceae)

Sympatric populations of Symphionema montanum R.Br. and Isopogon anemonifolius (Salisb.) Knight showed overlapping flowering periods during November 2009 in the Blue Mountains (New South Wales, Australia). Symphionema montanum has porose anthers encircling the protruding style, and lacks a pollen presenter. In contrast, sessile, longitudinally dehiscent anthers of Isopogon anemonifolius deposit pollen grains on the subterminus of the style (pollen presenter). Neither species secretes nectar. The majority of foragers on Symphionema montanum were polylectic, female bees (Halictidae). Their pollen foraging resembled sonication and shaking. Polylectic, female bees (Colletidae) were dominant foragers on Isopogon anemonifolius grasping styles with their mandibles while scraping the pollen presenter. Exoneura species (Apidae) visited both shrubs. Only two specimens of Callomelitta antipodes on Isopogon anemonifolius carried pollen of both shrub species. Most bees, collected on either shrub, carried the grains of their host mixed with one to six pollen morphotypes of co-blooming, nectariferous taxa. We report a positive correlation between an increase in bee size and the number of morphotypes carried but colletids of Isopogon anemonifolius carried fewer morphotypes than halictids on Symphionema montanum.
Impact of Materialistic Values on Impulsive and Compulsive Consumption via Status Consumption: A Research on Young Consumers

The impulsive and compulsive consumption that consumers cannot control has become a threat to individuals and countries due to their negative economic and social consequences. Materialism and status consumption are important negative personality traits underlying various consumers' behaviors. In this research, it is aimed to explore the impact of materialistic values and status consumption on impulsive and compulsive consumption. Cluster sampling method was chosen as sampling method. Students aged 17 to 24 year-olds were selected and 589 usable completed questionnaires were received by using self-completion survey method. According to the results of the model, materialistic values has significant and positive direct impact on status, impulsive and compulsive consumption respectively. In research model, since impact of status consumption on compulsive consumption is not significant, materialistic values have impact on compulsive consumption via status and impulsive consumption.

Flora and vegetation of the Eastern Goldfields Ranges: Part 7. Middle and South Ironcap,

A study of the flora and plant communities of part of Forrestania greenstone belt between Middle Ironcap and Hatter Hill (some 80 km ESE of Hyden), recorded a total flora of 345 taxa of which 342 were native and three were introduced. Three species of threatened flora and 29 taxa being considered for listing were found. Ten species are considered to be endemic to the range and a further eight species are restricted to similar landforms within 100 km of the range. A new species of Stenanthemum is only known from two populations. Despite considerable mining and exploration activity in the area, the flora and vegetation remain poorly known. Thirty-eight quadrats were established along the range system and data from these quadrats were used to define four community types. Differences in these community types were strongly related to edaphic gradients. Very little of the Forrestania vegetation system is reserved and the results of this survey support recommendations for the establishment of nature reserves to conserve this vegetation system.
Identification and synthesis of components for uncertainty propagation

For automotive structures, built-up of hundreds of components with property spread, knowing the effects of component variability and its propagation through the system assembly is important in order to mitigate noise and vibration problems. To increase the understanding of how the spread propagates into variability in built-up structures, both experimental and computational aspects are considered in this thesis. In the first part of the thesis, methods to identify models from experimental data are developed. Physical insight is often required for accurate experimental models. To this end, two-phase state-space system identification algorithms are developed where physically motivated residual states are included and physically motivated constraints are enforced. The developed identification algorithms are used together with finite element model updating to investigate the variability in dynamical properties between nominally identical components. Furthermore, the accurate and physical experimental models are used in synthesis with the updated finite element models. It is shown that experimental-analytical synthesis of complex and modally dense structures is possible, and that the component variability can be predicted in such assemblies. In the second part of the thesis, methods to reduce the computational cost of variability analysis are developed. An efficient multifidelity interface reduction method is developed for component synthesis. It is also shown that modal truncation augmentation vectors can be computed efficiently from the multifidelity interface reduction basis. Lastly, an efficient uncertainty propagation method is developed, based on a second-order modal model. Utilising several approximations, it is shown that industrial-sized models can be handled with small loss in accuracy compared to a purely Monte Carlo based approach.
Nutritional status of elderly assisted in primary care and their relationship with social determinants of health

ABSTRACT Objective To review the influence of social determinants of health in the nutritional status of the elderly assisted in a primary care Unit in a Recife, Pernambuco, Brazil, community. Methods This was a cross-sectional study with an analytical approach. The universe was composed of 129 elderly attending a family health unit in Recife, Pernambuco, Brazil. The data were collected according to a protocol. The effect of the association of independent variables with the body mass index was estimated using hierarchical logistic regression models, simple and multiple multinomial. The significance level was set at 5%. Results There was a higher percentage of elderly people with excess weight (52.34%) in the assessment of body mass index. On analysis of the Mini nutritional assessment, the risk of malnutrition was 38.76%. On analysis of the calf circumference 13.39% of the elderly were malnourished. In the final model, the criteria for maintaining the elderly patients were the following: excess weight, marital status, hypertension, osteoarthritis and sewer destination. Elderly widowers had a higher chance (OR=5.17) of having excess weight and not to have sewage network serving their home and be hypertense (OR=2.71 e 2.83). The fact that the elderly have osteoarthritis also indicated a greater chance (OR=3.76) that they present excess weight. Conclusion Among the social determinants of health, the nutritional status of the elderly was associated with marital status, high blood pressure, osteoarthritis and basic sanitation. The social setting of the elderly is associated with their nutritional status.
In vitro Ultrasonic Potentiation of 2-Phenylethynesulfonamide/Magnetic Fluid Hyperthermia Combination Treatments for Ovarian Cancer

Background Magnetic Fluid Hyperthermia (MFH) is a promising adjuvant for chemotherapy, potentiating the action of anticancer agents. However, drug delivery to cancer cells must be optimized to improve the overall therapeutic effect of drug/MFH combination treatments. Purpose The aim of this work was to demonstrate the potentiation of 2-phenylethynesulfonamide (PES) at various combination treatments with MFH, using low-intensity ultrasound as an intracellular delivery enhancer. Methods The effect of ultrasound (US), MFH, and PES was first evaluated individually and then as combination treatments. Definity® microbubbles and polyethylene glycol (PEG)-coated iron oxide nanoparticles were used to induce cell sonoporation and MFH, respectively. Assessment of cell membrane permeabilization was evaluated via fluorescence microscopy, iron uptake by cells was quantified by UV-Vis spectroscopy, and cell viability was determined using automatic cell counting. Results Notable reductions in cancer cell viability were observed when ultrasound was incorporated. For example, the treatment US+PES reduced cell viability by 37% compared to the non-toxic effect of the drug. Similarly, the treatment US+MFH using mild hyperthermia (41°C), reduced cell viability by an additional 18% when compared to the effect of MH alone. Significant improvements were observed for the combination of US+PES+MFH with cell viability reduced by an additional 26% compared to the PES+MFH group. The improved cytotoxicity was attributed to enhanced drug/nanoparticle intracellular delivery, with iron uptake values nearly twice those achieved without ultrasound. Various treatment schedules were examined, and all of them showed substantial cell death, indicating that the time elapsed between sonoporation and magnetic field exposure was not significant. Conclusion Superior cancer cell-killing patterns took place when ultrasound was incorporated thus demonstrating the in vitro ultrasonic potentiation of PES and mild MFH. This work demonstrated that ultrasound is a promising non-invasive enhancer of PES/MFH combination treatments, aiming to establish a sono-thermo-chemotherapy in the treatment of ovarian cancer.
Process rates of nitrogen cycle after harvesting in no-till and ploughed agricultural clay soils

No-till is considered an advantageous agricultural practice for the environment because soil erosion is decreased compared to ploughed soil. However, for an overall evaluation of the benefits and disadvantages of this crop production method, it is also important to understand the soil nutrient cycling in no-till fields. Little is known about how the gross rates of the different processes of nitrogen (N) cycle are affected by tillage practices in agroecosystems in a northern cold climate. Our study was designed to obtain information about gross soil N process rates in boreal no-till and moldboard ploughed spring barley fields after autumn harvesting. Gross organic N mineralization into ammonium (NH4) and NH4 immobilization were the most important N transformation processes in the soil and their rates were higher in no-till soil than in ploughed soil. Regardless of the higher mineralization rate, the gross rate of NH4 oxidation into nitrate (NO3) was clearly lower in no-till soil. This was explained by higher NH4 immobilization in no-till soil. The lower NH4 oxidation rate in no-till soil decreased the risk for NO3 leaching, which supports the promulgated environmental benefits of this practice.
Investigation of the effects of sun-dried apricot with different sulfur levels on oxidative stress markers

Objective: Apricots are mostly consumed in dried form worldwide. Studies are reporting some allergic effects of dried apricot because of its content of sulfur, which is used in the drying process. Therefore sulphur content has been limited by many countries. This study was conducted to determine the effects of sun-dried apricots with different sulfur contents on nitric oxide (NO), malondialdehyde (MDA) and glutathione (GSH) that are among the markers of oxidative stress. Methods: A total of 84 Wistar albino rats were divided into groups as control, sun-dried apricot, 1000, 2000, 3000 and 4000 ppm sulfured groups. At the end of the 12th week, rats were sacrificed under general anesthesia. NO, MDA and GSH levels were studied at the end of the experiment from the ovarian and testicular tissues of the rats. Results: No statistically significant differences were found among the groups in terms of NO, MDA and GSH in the ovarian and testicular tissues removed from the rats Conclusion: We claim that sulfur amount of dried apricots is not affect on reproductive system. This study is guiding further studies that will be conducted against the restrictions in sulfur used in the drying process of dried apricots, which is economically very important for dried fruits sector.
