Influence of the chemical structure of rapeseed oil-based polyols on selected properties of polyurethane foams

In this work, we report on obtaining rigid polyurethane foams with biopolyols based on rapeseed oil. The biopolyols with different functionality were synthesized in a two-stage reaction of oil epoxidation and oxirane ring opening with 1-hexanol (P_1Hex) and 1,6-hexanediol (P_1.6Hex) and their properties were characterized (Table 2, Figs. 1–3). Next, they were used to replace petrochemical polyols in foams by up to 60% by mass (Table 1). The introduction of the biopolyols into the polyurethane systems affected their reactivity (Fig. 4). The replacement of the petrochemical polyols with the biopolyols caused changes in the cell structure (Tables 3, 4) and the physical and mechanical properties of the resultant materials (Table 5).
Cluster concentrations and virial coefficients for adhesive particles

The cluster concentrations and virial coefficients for systems of two‐ and three‐dimensional particles obeying Baxter’s adhesive potential are reported, up to the (exact) fourth virial term. The exact radial distribution function displays an infinite series of Dirac‐delta singularities which are absent in the Percus–Yevick approximation. The coefficient of the first of these singular diagrams is calculated.
Nanoclusters in magnetoresistance

Abstract Electronic phase separation is one of the most exciting findings during the study of strongly correlated electron systems in past decades. Inhomogeneities at the nanoscale have been proven to not only play a key role in the material properties but also challenge the fundamental concepts of condensed matter physics. In rare earth doped manganites, a nanoscale phase with unique structural modulations has attracted particular attention because of its relationship with the renowned behavior of the material, colossal magnetoresistance (CMR). Direct observations of the nanoscale phases are usually difficult but necessary to unravel the controversies and unveil the underlying physics in this case. In this review paper, recent achievements of direct imaging of the nanoscale phase are shown by using advanced transmission electron microscopic techniques correlated with the material property measurements. Based on those results, the relationship between the nanoscale phase and the CMR effect was established, and unexpected magnetic and physical properties of the nanoscale phase were found. Although the microscopic origin of the nanoscale phase is not fully interpreted yet, the findings here shed light on the pathway to a deeper understanding of the mechanism of CMR and other properties in these materials.
Coordination under loss contracts

In this paper we study the e↵ects that loss contracts—prepayments that can be clawbacked later—have on group coordination when there is strategic uncertainty. We compare the choices made by experimental subjects in a minimum e↵ort game. In control sessions, incentives are formulated as a classic gain contract, while in treatment sessions, incentives are framed as an isomorphic loss contract. Our results show that loss contracts reduce the minimum e↵orts of groups and worsen coordination between group members, both leading to lower payo↵s. However, these results depend strongly on the group’s gender composition; groups with a larger proportion of women are better at coordinating and exert more e↵ort.
Effect of pre and post emergence herbicides on growth, yield and economics of wheat

A field experiment was carried out at Research Farm, Department of Agronomy, G.H. Raisoni University, Chhindwara, Madhya Pradesh during Rabi season 2019-20, on effect of pre and post emergence herbicides on growth, yield and economics of wheat. Nine herbicide treatments comprised of post emergence application of Pendimethalin @1.0 Kg a.i. ha as pre-emergence 2 DAS, Metsulfuron methyl @ 3 and 4 g a.i. ha POE at 18 DAS, Metribuzin @ 131 and 175 g a.i. ha POE at 18 DAS, 2,4D @ 563 and 750 g a.i. ha POE at 18 DAS, weed free and weedy check. The experiment was laid out in randomized block design with thrice replication. The experimental results revealed that the growth attributing characters of wheat crop viz., plant height and dry matter accumulation plant-. Maximum grain yield (47.17 q ha), straw yield (69.22 q ha), gross monetary returns (95738 Rs. ha), net monetary returns (58166 Rs. ha) and benefit cost ratio (2.55) were recorded under application of pendimethalin @ 1.0 Kg a.i. ha as pre-emergence at 2 DAS as compared to rest of the treatments.
White-light time-resolved reflectance spectroscopy for monitoring constituents concentrations in layered diffusive media

We performed reflectance measurements with a time-resolved white-light spectroscopy system to monitor concentrations changes in a two-layer liquid phantom with optical properties similar to human tissues. By varying the concentrations of three inks with different spectral features, we changed the absorption coefficient of the upper and lower layer to simulate either haemodynamics changes in the muscle covered by adipose layer, or functional brain activation with systemic response in the scalp. Data were analyzed by a time-resolved spectrally constrained fitting method based on a homogeneous model of photon diffusion. Although this approach is based on a homogeneous model and employs a single 2cm source-detector distance, the technique is able to monitor changes in the lower layer, while it is scarcely affected by variation in the upper layer. Preliminary in vivo measurements have been performed on one healthy volunteer to monitor oxy- and deoxy-haemoglobin changes in the muscle during arterial occlusion and in the brain during a motor task. Even if the overall sensitivity of the technique is reduced, in vivo results are in general agreement with the findings of dedicated system for tissue oximetry.
Supplementary material to "Mesospheric gravity wave activity estimated via airglow imagery, multistatic meteor radar, and SABER data taken during the SIMONe–2018 campaign"

Abstract. We describe in this study the analysis of small and large horizontal scale gravity waves from datasets composed of images from multiple mesospheric nightglow emissions as well as multistatic specular meteor radar (MSMR) winds collected in early November 2018, during the SIMONe–2018 campaign. These ground-based measurements are supported by temperature and neutral density profiles from TIMED/SABER satellite in orbits near Kühlungsborn, northern Germany (54.1° N, 11.8° E). The scientific goals here include the characterization of gravity waves and their interaction with the mean flow in the mesosphere and lower thermosphere and their relationship to dynamical conditions in the lower and upper atmosphere. We obtain intrinsic parameters of small and large horizontal scale gravity waves and characterize their impact in the mesosphere region via momentum flux and flux divergence estimations. We have verified that a small percent of the detected wave events are responsible for most of the momentum flux measured during the campaign from oscillations seen in the airglow brightness and MSMR winds. From the analysis of small-scale gravity waves in airglow images, we have found wave momentum fluxes ranging from 0.38 to 24.74 m2/s2 (0.88 ± 0.73 m2/s2 on average), with a total of 586.96 m2/s2 (sum over all 362 detected waves). However, small horizontal scale waves with flux > 3 m2/s2 (11 % of the events) transport 50 % of the total measured flux. Likewise, wave events having flux > 10 m2/s2 (2 % of the events) transport 20 % of the total flux. The examination of two large-scale waves seen simultaneously in airglow keograms and MSMR winds revealed relative amplitudes > 35 %, which translates into momentum fluxes of 21.2–29.6 m/s. In terms of gravity wave–mean flow interactions, these high momentum flux waves could cause decelerations of 22–41 m/s/day (small-scale waves) and 38–43 m/s/day (large-scale waves) if breaking or dissipating within short distances in the mesosphere and lower thermosphere region. The dominant large-scale waves might be the result of secondary gravity excited from imbalanced flow in the stratosphere caused by primary wave breaking.
Selected Properties of Formaldehyde-Free Polymer-Straw Boards Made from Different Types of Thermoplastics and Different Kinds of Straw

This research investigated the effects of different thermoplastics types and different kinds of straw on selected properties of polymer-straw boards. Polyethylene, polyethylene, and polystyrene of virgin and of recycled origin were used for bonding the boards. Three kinds of straw were used: rape (Brassica napus L. var. napus), triticale (Triticosecale Witt b m.), and rye (Secale L.). Five-layer polymer-straw boards were produced. The obtained boards differed in both the materials they were made of and the moisture content (7, 25, and 2% for the core, the middle, and the face layers, respectively), and 30% of straw particles were substituted with thermoplastics added to the face layers. It was found that properties of polymer-straw boards strongly depend on both the kind of straw and the type of polymer used. The best mechanical properties were obtained for rye straw and polystyrene or recycled polymers, whereas the best hydrophobic properties were observed for rape straw combined with recycled polyethylene or polypropylene. Although recycled polymers improved the hydrophobic properties of the boards, they impaired their mechanical properties in comparison with the reference ones. However, in terms of bending strength, they still met the requirements for heavy duty load-bearing boards for use in humid conditions (20 MPa for P7 boards according to EN 312).
Evaluation of knowledge and attitudes towards kidney transplantation in patients undergoing hemodialysis at Muhimbili National Hospital, Tanzania.

Renal replacement therapy (RRT) is the treatment of choice for patients with End Stage Renal disease (ESRD), RRT include dialysis and kidney transplantation. Some sub-Saharan African countries including Tanzania have improved nephrology services dialysis and kidney transplant. This study aimed to assess knowledge, attitude and practices towards kidney transplantation among patients undergoing dialysis at Muhimbili National Hospital. This was a hospital based cross-sectional study that was conducted at Muhimbili National Hospital. A total of 190 patients were interviewed, majority were males 133(70%) with the age range of 18-80 years. Most patients 183(96.35%) were aware of Kidney transplantation the main source of information 175(95.6%) being hospital with 159 (86.9%) patients being aware of rules guiding kidney transplantation and 166 (90.7%) were aware of lifelong medication use after kidney transplantation. Knowledge on transplant was noted in 115(62.8%) with all of them being willing to receive kidney from blood related relatives. Majority 188 (64.5%) patients were not sure whether live kidney donation was better than deceased kidney donation. Better knowledge may ultimately translate into the act of donation. Effective measures should be taken to educate people with relevant information with the involvement of media, doctors and religious scholars. Large proportion considers Kidney Transplant positively but it limited by shortage of donors.
Linear and cyclic sweep voltammetry at a rotating disk electrode. A digital simulation

The transport equation for the rotating disk electrode is solved numerically with appropriate boundary conditions for reversible and nonreversible redox reactions. A comparison of the computational mode with experimentel data is presented. The adaption of a steady state under variations of experimental parameters upsilon (scan rate) and omega (angular frequency of rotation) is investigated. It is shown that a triangular voltage scan can be used to indicate the attainment of a steady state in every zone of the current-voltage curve.
Weed control efficiency and productivity in rice-fish-duck integrated farming system

Rice farming integrated with fish and ducks potentially provides ecological services and supports effective management of weeds which cause rice yield losses due to growth competitiveness with the available resources and productivity. Present study investigated the efficacy of integrating fish and duck in rice farming for controlling weed infestations and their impacts on productivity and economics of the system. Appraisal on diversity of weeds indicated that grassy weeds (Echinochola colona, Echinochola crusgalli) and sedges (Cyperus difformis, Cyperus iria, Fimbristylis miliacea) were prevalent in rice during tillering stages, while broad leaf (Ludwigia adscendens, Sphenoclea zeylanica) and aquatic weeds (Marsilia quadrifolia, Otellia alismoides, Vallisneria spiralis, Limnophila indica, Ceratophyllum demersum, Hydrilla verticillata) were abundant during active tillering and panicle initiation stages of rice. A significant reduction in weed density and weed biomass was observed in rice-fish (RF), rice-duck (RD) and rice-fish - duck (RFD) integration. However, weed control efficiency (WCE %) was significantly (p<0.05) higher in RFD. The weed biodiversity in terms of species richness (Simpson’s index) and species diversity (Shannon-Wiener index) decreased significantly, while Pielou evenness community index increased in RFD, signifying weed community composition was highly diversified with reduction of formerly dominant weed species. Rice agronomic characteristics, productivity and economic returns were higher in integrated system indicating over all improvements in ecology and productivity. Better growth of fishes accrued with RFD integrated system, possibly, due to the better nutrient availability. Thus, fish and duck can be used as bio-control agents for weed management in rice farming for enhancing productivity in areas where application of chemical herbicides may be partially or totally eliminated in transplanted lowland system.

Modification of published procedures are described for the preparation of humulinic acids, dehydrohumulinic acids and hulupone, using iso-α-acids as starting material. These procedures provide facile routes for preparation of these compounds in higher yields than was hitherto reported, and also in sufficient purity for their use as standards in quantitative High Performance Liquid Chromatography. An alternative and more feasible route to hulupones, using β-acids as starting material, is also outlined.
Structural Equation Modelling of Teaching Quality on Students’ Satisfaction

Students are the main, vital, and central customers that must be served in a college. The college success is characterized by the quality of services provided, and service quality can be identified through student satisfaction. Therefore, knowledge is needed related to variables that affect student satisfaction, especially in the learning process. This study suspects that the knowledge and teaching methods used by educators in the learning process, the depth of material delivered, the implementation of the learning process, the clarity of the assessment of learning outcomes, and the affective interactions of lecturers and students affect the level of student satisfaction. This study uses the Structural Equation Modeling-Partial Least Square (SEM-PLS) with the Bootstrap parameter estimation method. The results showed that all the indicators forming the six latent variables used in this study were significant, so the models met the fit category. The results showed there was a positive and significant effect of the quality of teaching on the level of student satisfaction in the learning process by 19%. However, based on the five variables forming the quality of teaching, only the variable knowledge and teaching methods of lecturers have a significant effect on the level of student satisfaction.

Examining Parent–Child Spatial Play Interaction Using Traditional Toys and Touch Screen Tablets

SYNOPSIS Objective . The context of play has changed dramatically over the past decade with the ubiquitous presence of mobile technologies available to children in and outside the home. Despite increasing use of interactive technological devices at home, the quality of parental interactions in these 2D digital play contexts, relative to traditional 3D play contexts, remains relatively unexplored, especially in the domain of geometry. Design . The present study examines parental support and scaffolding of 32 parent–child dyads (16 girls, 16 boys; M age = 51.16 months) engaged in interactive play during two home visits, one involving 3D physical blocks and puzzles and the other with 2D virtual blocks and puzzles presented through apps on a tablet. Parental interactions were assessed for four scaffolding qualities (i.e., affection, encouragement, responsiveness, and teaching) and two interactional styles (i.e., child-directed and parent-directed) for 10 min of each play session. Results . Overall, parents actively scaffolded children with varied positive supports in both play contexts using a predominantly child-directed interactional style. Differences were found for the quality of parental interactions across 3D and 2D play contexts. Fewer parental scaffolds involving responsiveness and teaching were provided in the 2D context. Conclusions . Effective, yet differing, supportive parental scaffolding occurs when parents engage in both traditional and virtual spatial play. Through joint play with their children, parents can support the acquisition of foundational concepts in geometry.

Laboratory and Greenhouse Evaluation of Quicklime Sources for Suitability as Agricultural Liming Materials

Abstract Quicklime or burnt lime (CaO), is a highly soluble liming material recognized as an acceptable means for neutralization of acid soils in the United States. Blending CaO and MgO with agricultural lime (CaCO3) may prove an alternative to ground agricultural limestone for raising soil pH and providing fertilizer Ca and Mg for crop growth. The objectives of this study were to determine the chemical properties of several CaO, MgO, and CaCO3 liming blends compared to carbonate limestones, and analyze their respective effects on soil solution chemistry and shoot yield of a sorghum-sudangrass hybrid grown under greenhouse conditions. Three formulations of oxide liming materials (CaO, CaO + CaCO3, and CaO + MgO + CaCO3) were evaluated in the laboratory to determine their respective effectiveness as soil amendments compared to two dolomitic limestones (ground and pelletized) and reagent-grade calcium hydroxide [Ca(OH)2]. A 150-day incubation study was conducted to determine the effects of liming materials on soil pH and extractable nutrients, and a greenhouse study was completed to observe the effects of liming materials and rates on the herbage yield of a sorghum-sudangrass hybrid. Oxide liming materials averaged higher calcium carbonate equivalence (CCE) than ground and pelletized dolomitic limestones. An incubation study found CaO, CaO + CaCO3, and CaO + MgO + CaCO3 resulted in rapid pH adjustments (from pH 4.1 and 4.4 to 6.0 +) at one day after test initiation for two soil types and gave higher mean pH values than carbonate limes when applied at equivalent rates based upon CCE. Oxide liming materials also resulted in higher concentrations of soil extractable calcium (Ca) and magnesium (Mg), and the use of all liming materials, regardless of chemical form, alleviated Al toxicity. In a nine week greenhouse bioassay, all oxide liming materials and reagent-grade Ca(OH)2 were applied at 1/2X, 1X, and 2X the recommended application rate of ground dolomitic limestone based on CCE, resulting in similar or higher shoot yields comparatively at conclusion of this study. Because oxide liming materials have higher CCE values and provide more water-soluble sources of fertilizer Ca and Mg compared to ground and pelletized limestone, producers have potential for obtaining a more complete neutralization of acid soil conditions and shoot yields similar to or higher than those obtained with dolomitic limestone, using less material in the process. This study did not determine if changes in current liming practices would result in reductions of total fertilizer costs per year using oxide limes in place of carbonate forms.
