Rheological Behavior of Suspensions Dispersed in Non-Newtonian Matrix

Abstract Suspensions composed with silica particles or cellulose fibers dispersed in glycerin and/or xanthan aqueous solutions were formulated with solids volume fraction varying up to 15 and 10 % for silica and cellulose dispersions, respectively. In addition, xanthan was added to the aqueous solutions (water or 82 % glycerin + water) at concentrations of 0.005, 0.1, and 0.2 % to impart non-Newtonian character to matrices, and results were compared to the Newtonian systems, without xanthan addition. Even though developed for suspensions in Newtonian fluids, Krieger-Dougherty and Eilers models described properly the influence of solids content on the flow behavior of suspensions in non-Newtonian fluids. Generally, increasing cellulose particles concentration led to an increase on the suspension pseudoplasticity, while for silica particles such increase was more discrete. Low deformation rheological measurements showed that glycerin-containing matrices were more independent on frequency as compared to suspensions of aqueous xanthan solutions. Results showed that, besides particles characteristics, the rheological properties of the suspending matrix are crucial for determining the arragements and flow properties of suspensions.
Compensation for imaging errors in EUV lithography

In this paper we will examine some of the fundamental imaging effects that must be considered with the intended implementation of Extreme Ultraviolet Lithography (EUVL). The paper will show how simulation can be used to examine issues such as image placement and the effect of mask dimension errors. We will show how the exact structure of an EUV mask need not be simulated, but the use of Fourier boundary conditions may be used as an accurate substitute, considerably speeding up computation time. Further, this technique is used to show the positional error that is inherent in an off-axis reflective optic design such as that proposed for EUV exposure tools. Any dimension error that is produced on the mask will not linearly transfer to the printed wafer, this is known as Mask Error Factor (MEF). We will present simulation data showing that the off-axis nature of the incident light leads to different rates of change of printed CD, at defocus, for features orientated perpendicular to each other. These effects must then be taken into account when we consider reticle error budget for EUVL technology.
Dynamic Properties of Fiber-Modified Overlay Mixture

Cores and slabs of fiber-modified asphalt overlay were taken from a series of test sections constructed on two highways in Indiana. Extensive laboratory investigations were conducted to evaluate the fiber-modified asphalt mixtures. Laboratory tests included physical properties, beam fatigue, and complex modulus. Because of a lack of a standard method for fiber extraction, three fiber extraction methods were evaluated. Test results show that more than 95 percent of fiber can be extracted from paving mixtures. Actual fiber contents in test sections were found to be different from target fiber contents by a significant amount. Physical property tests show that the addition of fibers is related to a higher percentage of air voids in the in situ pavement. Results of fatigue tests indicate that fibers increase the fatigue life of overlay mixture. There are inconsistencies in the significance of fiber on both dynamic modulus and phase angle. However, the results do indicate that the addition of fibers will change the viscoelastic properties of mixtures. There is no statistical difference in dynamic modulus and phase angle among the mixtures with different fiber contents.

Consumer profile and factors determining the purchase of agroecological products. A case study: UNIMINUTO Agroecological Fair and Minuto de Dios Solidarity Market, Colombia

This research sought to characterize consumers and consumption in the UNIMINUTO Agroecological Fair and the Minuto de Dios Solidarity Market, which both have a low number of consumers and sales. A survey was designed and implemented through a Google form and in person, between September and October 2019. The total sample was 146 consumers (90% reliability, 5% error). The results were analyzed through descriptive statistics and comparison with other studies. The consumer’s profile is mostly university students of natural sciences, young adults of low and low-middle income strata from small households, and women; the age, gender, and educational level are common features with similar studies. The consumer lacks knowledge about the products, the participatory certification, and pricing, which can be remedied through consumer education. The supply and quality of agroecological products must also be improved.
EFFECTIVENESS AND ECONOMY IN RUNNING

INTRODUCTION: The present study aims at the assessment of the effectiveness of running movements by a combination of approaches. For this purpose ‘inefficient mechanical work’ in the vertical and lateral directions was determined, as well as ‘conservation of mechanical energy’ by inter- and intra-segmental energy transfer. These parameters were related to total mechanical power, to physiological indicators of energy expenditure and to the state of physical training. METHODS: Ten untrained physical education students and 10 highly-trained runners (specialists) ran 2000m 3-5 times with different running speeds on a 200m indoor track. Before and after each 2000m-run their heart rate and blood lactate were recorded. In 4 subjects wearing a portable spirometer, O2 consumption and respiratory quotient were determined. One step cycle was filmed by two highspeed cameras (LOCAM) (150 frames/sec) in the 1. , 9. and 10. round of each 2000m run. Three-dimensional coordinates of 21 points defining a 15-segment HANAVAN model were constructed using the DLT technique. The data were smoothed using a low pass filter with a cut-off frequency of 15 Hz. Mechanical power outputs were calculated by the changing of the translational, rotational and potential energy of each segment. The energy transfer within and between the segments was calculated using the method of Winter (1979). To describe the effectiveness of the running movement we calculated segmental work in lateral and vertical directions and energy transfer in relation to total mechanical power (Ptot). To determine the differences between students and specialists we computed a one-way analysis of variance (ANOVA) with running velocity as a covariate. RESULTS: Table 1 Group differences of physiological parameters, training and effectiveness mean ±std. -dev. [table] CONCLUSIONS: The results of this study indicate an inverse relationship between metabolic energy expenditure during running and the effectiveness of the running technique. The more economical running technique is characterized by a smaller transfer of segmental power in the vertical and transversal directions and a higher degree of inter- and intra-segmental energy transfer.
Scattering of electromagnetic waves by arrays of conducting and dielectric cylinders

A method is developed that enables the solution of scattering by a finite number of cylinders in a convenient and accurate form. It is based on an analytic formulation using the boundary value problem and an application of a point matching technique. The method is then applied to study the scattering properties of both conducting and dielectric cylinders. It is also used to determine the size and spacing of passive scatterers to improve the directivity of linear antennas. In the latter case, a combination of the present method and a space perturbation technique is utilized to optimize the antenna gain.
Pesticide handling and human health: Conventional and organic cotton farming in Benin

Synthetic pesticides can be detrimental to the health of humans, particularly when handled inappropriately, which is often the case in developing countries. We investigate to what extent using personal protective equipment (PPE) during pesticide application can mitigate the detrimental health effects of pesticides. Our empirical analysis is based on data from smallholder cotton farmers in Benin and includes both conventional cotton farmers who extensively use synthetic pesticides and organic cotton farmers who are only allowed to use bio-pesticides. Using per-capita health expenditure as proxy for the health of the farmers, our results show that conventional cotton farmers generally have significantly poorer health than organic cotton farmers because most conventional farmers wear insufficient PPE when spraying pesticides. While PPE use vastly improves the health of conventional farmers, we do not find a statistically significant effect on the health of organic cotton farmers, which could indicate that bio-pesticides have much smaller detrimental health effects than synthetic pesticides. However, conventional farmers have a similar state of health as organic farmers when they use four or more PPE items. Hence, measures that encourage conventional cotton farmers to use more PPE during pesticide spraying or to adopt organic farming would substantially improve these farmers’ health.
Üniversite Öğrencilerinin Web Ortamında Bilgi Arama-Yorumlama Stratejilerinin Demografik Değişkenlere Göre İncelenmesi

Millions of people all over the world use the internet so as to communicate or search a topic to get information today. There are several sources about any topic on the internet. Even though there are some misleading ones, there are perfect ones, as well. Therefore, what is important about this issue is to determine whether this electronically acquired information is reliable, true and of high quality or not. If it is, to what extent it is reliable? The purpose of this research is to determine whether information searching and commitment strategies of university students vary according to demographic variables. Quantity method was used in the research, and relational scanning model was preferred among all scanning models. 370 students at Education Faculty, Science and Literature faculty and Engineering faculty of Kocaeli University were included in this research. The questionnaire of information searching and commitment strategies on the internet developed by Wu and Tsai (2005) was used in the research. At the end of the research, it was observed that university students use developed strategies more than others. The highest grade about the strategies of information searching and commitment goes to the statement: ‘ I can combine the information that I collect from various web sites, whenever I need to get information. ’ It can be expressed that university students have the necessary ability to compare the information from different web sites and combine it so as to reach the accurate and reliable information. Anova was used to determine whether the strategies of searching and commitment of information vary according to the frequency of daily internet use. No significant difference was observed, though.
Stiffness of dowel-type fasteners in timber–concrete joints

The mechanical behaviour of timber–concrete structures is significantly influenced by the stiffness of the joints, both with regard to deformations and to strength. This paper analyses the experimental and numerical assessment of the stiffness of timber–concrete joints, made with dowel-type fasteners. The objective of this analysis is to provide information to be used in the design of timber–concrete composite structures. In order to achieve this, two approaches were used: experimental tests with timber–concrete joints and numerical predictions using models available in the literature. As part of the experimental assessment, shear tests were performed with various joint configurations aiming to be representative of a wide range of practical conditions. The results obtained are presented and discussed. In terms of numerical assessment, two types of models were considered: analytical models, based on the beam on elastic foundation and empirical models. The results obtained in the experimental tests are comp.
Is it a boy or a girl? Newborn gender and household portfolio decisions by

This paper analyzes the role of newborn gender in household investment decisions. Parenting a new baby is associated with a reduction of cash and an increase of the share of financial wealth allocated to longer term investments. The reallocation is however gender-heterogeneous: the increase in the share of financial wealth allocated to risky assets when parenting a girl is reduced for households parenting a new baby boy. The effect is driven by the first child. Our results suggest that household investment decisions are affected by the newborn gender. While the reallocation happening after the birth of a baby is optimizing as it increases both portfolio diversification and return, there is no evidence of a positive effect of gender-driven financial decisions.

Gunn instabilities in power HEMTs

Experimental and theoretical evidence of the formation of ‘transverse’ Gunn dipoles in an Al0.23Ga0. 77As/In0.23Ga0. 77As delta doped HEMT is presented. Monte Carlo simulations predicted that the dipoles would first cause a sudden reduction in current followed by a gradual upturn. These predictions were in excellent agreement with the experimental observations.
Design and Testing of a Foundation Raised Oscillating Surge Wave Energy Converter

DESIGN AND TESTING OF A FOUNDATION RAISED OSCILLATING SURGE WAVE ENERGY CONVERTER September 2021 Jacob R. Davis, B.S., University of Massachusetts Amherst M.S.M.E. University of Massachusetts Amherst Directed by: Professor Krish Thiagarajan Sharman Our oceans contain tremendous resource potential in the form of mechanical energy. With the ability to capture and convert the energy carried in surface waves into usable electricity, wave energy converters (WECs) have been a long-held aspiration in ocean renewable energy. One of the most popular wave energy design concepts is the Oscillating Surge Wave Energy Converter (OSWEC). True to their namesake, OSWECs extract energy from the surge force induced by incident waves. In their most basic form, OSWECs are analogous to a bottom-hinged paddle which pitches fore and aft in the direction of wave motion. Most commonly, OSWECs are designed for nearshore use in water depths of less than 20 m where they are mounted to the seafloor at their point of rotation. This work seeks to explore the response and design loads of foundation raised OSWECs for use in deeper waters, unlocking new and greater areas of wave energy resource. A foundation raised OSWEC was designed, built, and tested in a laboratory wave tank. The scale OSWEC was modeled using two methods and compared to data from the experiments. The first of these methods is a highly efficient, analytical approach which derives from the solution to the boundary value problem transformed into elliptical coordinates. Previous validation results demonstrate the analytical model is capable of reproducing results from higher fidelity numerical simulations with computation times on the order of seconds. The second approach combines hydrodynamic coefficients evaluated in WAMIT with the open-source time domain solver WEC-Sim. Two model configurations were observed: the scale OSWEC with no external attachments, and the OSWEC with external torsion springs, as to excite the model at its natural period. The pitch displacement, surge and heave forces, and pitch moment were recorded at the base of the model foundation in response to regular waves with periods ranging from 0.8 s to 2.8 s and heights from 1.5 mm to 14.3 mm. The experimental results show the surge force and pitch moment increase drastically across the observed period range from the addition of external springs. The

Study on Flapping-of-Wings Flight of Butterfly with Numerical and Experimental Analysis

This paper treats the flapping-of-wings flight of a butterfly, which is rhythmic and cyclic motion. The objective of this paper is to clarify the principle of stabilization of the flapping-of-wings flight. For the purpose, this study performs the experiment for the quantitative data acquisition and qualitative observation, derives models of a butterfly, and compares the actual and modeled butterflies. An experimental system with a low-speed wind tunnel is constructed for fundamental data of flapping-of-wings motion, where the system measures the aerodynamic force and the motion simultaneously by a measure and a optical measurement system. The measured data of flapping motion shows what degreeof-freedom are used for butterfly control. A dynamics model of a butterfly is derived for analyses by Lagrange’s method, where the butterfly is considered as a rigid body system. For the aerodynamic forces, a lumped-vortex method and a panel method are applied. Validity of the mathematical model is examined by comparing the measured data with the numerical results. A periodic orbit of a flapping-of-wings flight is searched so as to fly the butterfly model. Both models in the flapping-of-wings flight are unstable. The unstable level of the panel method model becomes small by considering free-vortices in wakes. It is shown that the wake-induced flow of the panel method has a kind of feedback stabilization eect.
Immunohistochemical Biomarkers in Oral Submucous Fibrosis - A Scoping Review.

INTRODUCTION This scoping review was done to study the immunohistochemical biomarkers involved in pathogenesis and malignant transformation (MT) of oral submucous fibrosis (OSF), in literature published from 2010 to 2021. METHOD The protocol was adapted from the Joanna Briggs Institute Reviewer's Manual (2017, and reported according to the PRISMA guidelines for Scoping Reviews (PRISMA-ScR). RESULTS Eighty-six studies included in this review reported 84 immunohistochemical (IHC) biomarkers in OSF: 9 epithelial markers, 29 connective tissue markers, 22 proliferative markers, and 24 other biomarkers that are transcription factors, cancer stem cell markers, cell signaling markers, proteins, and enzymes. The commonly reported IHC biomarkers were alpha-smooth muscle actin (α-SMA) and E-cadherin (7 articles each) followed by vascular endothelial growth factor (VEGF) and CD34 (6 articles each), p53, p63 and Ki67 (5 articles each). α-SMA, Ki67, CD105, and hTERT were significantly increased in oral squamous cell carcinoma arising in a background of OSF (OSCC-OSF) compared to OSF and normal subjects. CONCLUSION The identified surrogate IHC biomarkers reported in OSF in this scoping review require validation with long-term prospective studies to facilitate early diagnosis, for use in risk assessment, and plan appropriate treatment for OSF in clinical practice.
Encoderless position estimation for symmetric cage induction machines under loaded conditions

This paper presents sensorless position estimation using a conventional or "symmetric" cage induction motor. The rotor position information is obtained by high-frequency injection and using the modulating effect of the rotor slots. This makes true sensorless position control possible. The deteriorating effect of saturation harmonies for operation at full flux and higher loads is suppressed by using a harmonic compensation scheme based on parameters obtained from an automated commissioning process. Experimental results are shown, demonstrating sensorless position estimation at full flux and high loads. Initial experimental results are presented for encoderless position control under full flux.
Multi-decadal (1953–2017) rock glacier kinematics analysed by high-resolution topographic data in the upper Kaunertal, Austria

Permafrost is being degraded worldwide due to the change in external forcing caused by climate change. This has also been shown to affect the morphodynamics of active rock glaciers. We studied these changes, depending on the analysis, on nine or eight active rock glaciers, respectively, with different characteristics in multiple epochs between 1953 and 2017 in Kaunertal, Austria. A combination of historical aerial photographs and airborne laser scanning data and their derivatives were used to analyse surface movement and surface elevation change. In general, the studied landforms showed a significant acceleration of varying magnitude in the epoch 1997–2006 and a volume loss to variable degrees throughout the investigation period. Rock glaciers related to glacier forefields showed significantly higher rates of subsidence than talus-connected ones. Besides, we detected two rock glaciers with deviating behaviour and one that showed an inactivation of its terminal part. By analysing meteorological data (temperature, precipitation and snow cover onset and duration), we were able to identify possible links to these external forcing parameters. The catchment-wide survey further revealed that, despite the general trend, timing, magnitude and temporal peaks of morphodynamic changes indicate a slightly different sensitivity, response or response time of individual rock glaciers to fluctuations and changes in external forcing parameters.
