Chromosomal Changes in Prosopis glandulosa var. torreyana (Honey Mesquite) Species Widely Distributed in North America

A cytogenetic study using conventional surface-spread, air-dried, Giemsa-stained techniques were performed in somatic cells from six individuals of Prosopis glandulosa var. torreyana belonging to a population in northern Mexico. The results confirmed chromosome number 2n=28 and its karyotype generally consistent with that shown in other species of mimosoid whose karyotypes are characterized by a predominance of chromosomes with a medium or slightly displaced centromere and few subterminal centromeres. However, there were differences in chromosomal morphology concerning other Prosopis species involving chromosome size and the location, shape, and size of the satellites on the SAT chromosomes. The evidence of chromosomal remodeling, not previously described in this genus, favors its possible participation as a genetic isolation mechanism that would prevent the formation of viable hybrids, as has been recorded in other studies.
Radix-4 butterfly LSI in direct-imaging Waseda radio interferometer for a Pulsar survey

In the Nyquist rate direct-imaging interferometer at Waseda University, a radix-4 butterfly LSI has been developed for the spatial-temporal (2+l)D FFT processor to survey pulsars. In (2+l)D FFT, the first 2D FFT is a 2D directional finding spatial FFT processing for an 8x8 pixel image. The second ID FFT is a ID spectral finding temporal FFT processing for a 64ch frequency analysis in each 64 pixels. Since fewer multipliers are required in radix-4 FFT than in radix-2 FFT, we have implemented radix-4 algorithms in the present butterfly LSI. This implementation, using 512 radix-4 butterfly LSIs, could reduce the circuit size of the parallel and pipeline (2+l)D FFT processor. Additional functions, such as shift registers, digital filters and post-process sections, are also included in the LSI for a radio interferometric pulsar survey.
Tourists’ Souvenir Purchase Behavior and Retailers’ Awareness of Tourists’ Purchase Behavior in the Southwest

The purpose of this study was twofold: (a) determine retailers’ awareness of tourists’ souvenir purchase behavior and (b) provide guidelines for retailers concerning the souvenir purchase behavior of tourists in the southwestern United States. Two random samples were used, tourists (n = 398) and retailers (n = 307). Printed questionnaires included demographic questions respective to each sample and Likert-like scales (Souvenir Merchandise Assortment, Merchandise Selection Factors, Store Attributes). Data were obtained through a modified Salant and Dillman (1994) procedure and analyzed with AnswerTree® software. Retailers were somewhat aware of the souvenir purchase behavior of tourists when consideration was given to souvenir assortment, merchandise selection factors, and store attributes. Tourists wanted retailers to (a) carry souvenir assortments that included local foods and fine jewelry, (b) consider souvenir selection factors such as craftsperson’s reputation and motif or design of place visited, and (c) not emphasize store location in a high pedestrian traffic area. Implications for retailers to satisfy tourists in souvenir purchases are indicated.
Robust contact force estimation for robot manipulators in three-dimensional space

Abstract Information on contact forces in robot manipulators is indispensable for fast and accurate force control. Instead of expensive force sensors, estimation algorithms for contact forces have been widely developed. However, it is not easy to obtain the accurate values due to uncertainties. In this article, a new robust estimator is proposed to estimate three-dimensional contact forces acting on a three-link robot manipulator. The estimator is based on the extended Kalman filter (EKF) structure combined with a Lyapunov-based adaptation law for estimating the contact force. In contrast to the conventional EKF the new estimator is designed such that it is robust to the deterministic uncertainties such as the modelling error and the sensing bias. The performance of the proposed estimator is evaluated through simulations of a robot manipulator and demonstrates robustness in estimating the contact force. The estimation results show that it can be potentially used to replace the expensive force sensors in robot applications.

Challenges with displaying enhanced and synthetic vision video on a head-up display

Displaying video on a head-up display from an Enhanced Vision System camera or Synthetic Vision System engine presents some unique challenges not seen on conventional head-down flight deck displays. All information displayed on the HUD has to be seen against a background that can vary from bright sunlight to a dark night sky. The video has to include enough grayshade information to support visual identification of runway features and the image shown on the HUD has to be visually aligned to the real world accurately enough to support low-visibility operations at airports. The pilot needs to clearly see the image on the HUD but also needs to see the real world through the display when it can be seen with the naked eye. In addition, the video display cannot interfere with the display of existing flight information symbology.
A novel high efficiency UPS using improved inverter and DC to DC converter

The uninterruptible power supply (UPS) presented combines a rectifier of high input power factor, a DC/DC power converter and a pulsewidth-modulated (PWM) inverter. However, in the inverter circuit, because a divided choke snubber was devised, short circuit failure can be avoided without giving the drive pulse of switching element a dead time period. Also because an LD snubber was designed, the current surge and the voltage surge do not occur. The performance of the switched snubber, the effectiveness of the LD snubber and of the divided choke snubber were verified by the experiments. Experimental results of testing these schemes are reported. <<ETX>>
Fabrication of Transparent Composites from Pinaceae Wood Packaging Residues

In the 21st century, mankind has witnessed the rapidly development of all industries with a lot of new products in a variety of types and designs. However, this development has been also causing many problems with the society and the ecological environment such as a wasteful excess of products, exhaustive exploitation of natural resources, indiscriminate deforestation, and waste pollution affecting the living environment, ecosystem, and human health. Many organizations and governments are calling for environmental protection, limit waste emissions, and find good solutions to use the recycled materials as raw materials in production plants. This study would like to provide a solution which not only utilizes waste packaging Pinaceae wood for recycling as raw material but also supplies to the market with a green product responding to the durability requirements in fact. Pinaceae wood packaging residues were chemically processed through two stages. The amount of lignin extract from Pinaceae was determined by the method of Tappi 222 om-02 which was significantly influenced by the extraction parameters such as temperature, time and concentration of the treatment solution. Morphological modification of wood materials was analyzed by SEM micrographs. In particular, the mechanical properties of the Epoxy/TPW2 composite green material have been significantly improved with increasing up to 206–540 % compared to the original Pinaceae wood. The optical properties of the wood have completely changed from opaque pine wood with the optical transmittance of 8 % into transparent composite material with the optical transmittance up to 85 % using UV-vis spectroscopy analysis.
Drivers of respiratory healthcare demand in Acre state, Brazilian Amazon: a cross-sectional study

1.1 BackgroundThe scant knowledge on drivers of demand for respiratory healthcare in Brazilian Amazon, where the gap of human and physical healthcare resources is wide, is expanded with two surveys conducted at the west of the region in Acre state. Potential drivers, informed by a review of twelve recent papers, were classified in seven categories comprising the individual, household, community and macroeconomic dimensions.1. 2 MethodsOn-field quantitative structured surveys were conducted in 2017 and 2019 based in coupled conglomerate-quota-randomization sampling, with support of community health agents. Adults responded about their own or their children’s health. Whether physician care was sought to treat the latest episode of respiratory illnesses or of dry cough was analysed statistically with multiple non-linear regressions having as covariates the potential predictors informed by literature.1. 3 ResultsThe propensity to seek healthcare and to purchase medication was larger when targeting children rather than adults. Influenza was the most frequent cause of latest episodes of respiratory illnesses and dry cough, what makes the below-40% healthcare seeking rate worrying as it may sustain a considerable local contagion rate. Illnesses’ severity, including the pain experienced, were the main predictors, revealing that subjective perception exerted stronger influence than objective individual’s and households’ characteristics. The insignificance of education indicated that it was not the sole determinant of health literacy, the latter a more important driver, according to literature. Income was insignificant due to respondents relying almost uniquely on free healthcare offered by the Brazilian Health System.1. 4 ConclusionsResults suggest that subjective underestimation of respiratory illnesses’ consequences for oneself and for local society could motivate a refusal to seek treatment. This is in line with some previous studies but departs from those overemphasizing the role of objective factors. Social consequences, of, for instance, macroeconomic nature, needs highlighting, based on studies detecting a long-run relationship between healthcare demand, health and economic performance at national level. Microeconomic behavioural policy is needed to change subjective perceptions of symptoms and illnesses with nudges and educational interventions.
Extending the Ecological Interface Design process—Integrated EID

This article aims to extend the traditional Ecological Interface Design (EID) process. With the rapid pace of digitalization in technological systems, there is a need for a design process that can handle the systemic design goals and the experiential basis of interaction. Currently, the traditional EID is well‐positioned to address these challenges. However, methodologically, it needs to be substantiated to make it accessible for designers, designing for novel arenas, such as Industry 4.0. Further, substantiating the design process will help designers, engineers, and human factors researchers with an accessible pathway that links the design brief to the final interface form. Therefore, this article delves into the “design” basis in the work of the Risø group and other prominent EID researchers and practitioners. In addition, it draws from a variety of themes in the discipline of design that addresses methodology. In particular, key insights are drawn from the design methods movement (1960s—); design, communication, and complexity from the Ulm school of design, 1953–1968; cognitive research conducted on designers and design activities; and finally, interaction design and communication design processes and models. All of these insights have been used syncretically to create the new integrated EID (iEID) process. This new design process consists of nine stages divided into three phases of divergence, transformation, and convergence, converting the initial design brief to the final interface. The steps of iEID are demonstrated using the example of interface design for a “digital twin” in the manufacturing sector.

Capture Zone Comparison for Photovoltaic Microgrid-Powered Pump and Treat Remediation

AbstractPump and treat groundwater remediation systems typically rely on utility power to continuously pump contaminated groundwater to an above-ground treatment unit. The use of renewable energy for a pump and treat remediation system reduces the output of harmful greenhouse gases and the need for coal-based utility power. This paper describes a hypothetical renewable energy-powered pump and treat remediation system that uses an off-grid photovoltaic array to power a submersible solar water pump. The pump operates on an intermittent schedule predicted by available solar irradiance. The intermittently operated pump generates an effective capture zone defined by multiple transient capture zones. Effective capture zones are modeled using Visual MODFLOW and MODPATH and compared against a continuously pumped steady-state capture zone. The comparison showed that a renewable energy-powered intermittently pumped remediation system performs 90% as effectively as a utility-powered continuously pumped remediation s.
Local Heat Transfer Characteristics in Channels With Pin Fin and Pin Fin-Dimple Arrays

A comparative study was conducted to investigate the spatially-resolved local heat transfer characteristics of air turbulent flow in rectangular channels with pin fin and pin fin-dimple arrays. The spatially-resolved Nusselt numbers on the endwall surface of the pin fin and pin fin-dimple channels have been obtained and compared with each other. Compared with the pin fin channel, the pin fin-dimple channel shows distinguishing heat transfer characteristics on the wall beneath the main flow and the wake flow region. Due to the presence of the dimples in the pin fin arrays, additional strong vortex flows are generated near the wall beneath the main flow region, which distinctively increase the heat transfer rates there; however the turbulent mixing in the wake of the pin fins is reduced appreciably, which leads to decreased heat transfer rates in the wake.Copyright © 2011 by ASME
Renewable Energy Consumption and Sectoral Based Output

The study explores the effect of renewable energy consumption on sectoral output in the presence of government effectiveness. A regressions method was used to analyze data from 1989 to 2019. The result revealed evidence of the positive and vital impact of renewable energy consumption on the sectoral output of the manufacturing and construction sectors. Although the elasticity of government effectiveness is neutral, trade openness has revealed evidence of positive and significant impact on sectoral outputs. However, population growth does not have a favourable impact on sectoral outputs. Furthermore, renewable energy consumption is not essential in determining the agricultural sector, transportation sector and other sectors. To quickly diversify the economy, policymakers should further increase awareness and provide more incentives for renewable energy in these sectors
Causality and the Cox Regression Model

This article surveys results concerning the interpretation of the Cox hazard ratio in connection to causality in a randomized study with a time-to-event response. The Cox model is assumed to be correctly specified, and we investigate whether the typical end product of such an analysis, the estimated hazard ratio, has a causal interpretation as a hazard ratio. It has been pointed out that this is not possible due to selection. We provide more insight into the interpretation of hazard ratios and differences, investigating what can be learned about a treatment effect from the hazard ratio approaching unity after a certain period of time. The conclusion is that the Cox hazard ratio is not causally interpretable as a hazard ratio unless there is no treatment effect or an untestable and unrealistic assumption holds. We give a hazard ratio that has a causal interpretation and study its relationship to the Cox hazard ratio. Expected final online publication date for the Annual Review of Statistics, Volume 9 is March 2022. Please see http://www.annualreviews. org/page/journal/pubdates for revised estimates.
Application of a photonic crystal fiber LPG for vibration monitoring

A fiber optic sensor based on a long-period grating (LPG) inscribed in a photonic crystal fiber is investigated for vibration sensing for structural monitoring applications. In this paper, preliminary results are shown demonstrating the sensor ability to detect vibration induced in a test structure. The sensor frequency response when attached to a loudspeaker-acrylic plate stimulation system (tested in the range from 40 Hz to 2.5 kHz) is analyzed using an intensity based scheme with a tunable laser. An alternative interrogation scheme, where the vibration signal is retrieved from a spectral scan, is also demonstrated and analyzed showing promising characteristics for structural health monitoring.
An Optimized Micropropagation Protocol by Ex Vitro Rooting of Pear Rootstock OHF 333 (Pyrus communis L.)

Pear rootstock OHF 333 ( Pyrus communis L.), which is included in the US ‘Old Home’ × ‘Farmingdale’ series, is characterized by good compatibility with most other varieties, high yields, and a moderate degree of resistance to fire blight. Micropropagation in vitro has shown promise for rapid, large-scale cloning of disease-free plant material throughout the year. However, pear shoots are often recalcitrant to rooting, and this process is highly genotype-dependent. This study aimed to improve the micropropagation protocol by ex vitro rooting of pear rootstock OHF 333 ( Pyrus communis L. ‘Old Home’ × ‘Farmingdale’). Charkor, a new plant growth regulator of natural origin was used, which contains metabolism products of symbiotic fungus-endophytes of ginseng roots, as an alternative to synthetically produced plant growth regulators (PGRs). Microcuttings were obtained from in vitro cultured shoots and subjected to four different treatments for ex vitro rooting: 1 g L −1 1-naphthaleneacetic acid (NAA) (as a powder), 0.5 mL L −1 Charkor for 3 hr or 6 hr, or the same concentration of Charkor prepared as a powder. Microshoots dipped in sterile distilled water with no additional hormonal treatments served as controls. Cultures were kept in a growth chamber under a 16-hr photoperiod, with air humidity maintained close to 100% (above 96%) for 2 weeks and then gradually reduced to 60%. Data on final acclimatization rate (survival rate; %), mean number of roots per plant, stem and root length, mean number of leaves per plant, and final acclimatization rate were collected 90 days after transplanting to ex vitro conditions. All treatments induced a successful acclimatization rate of more than 31%. The highest survival rate (86%) and longest stems were achieved by treatment with 0.5 mL L −1 Charkor for 6 hr. The greatest mean number of roots per plant, root length, and number of leaves was achieved in the variant treated with 1 g L −1 powdered NAA.
