Adsorption of anionic surfactant (sodium dodecyl sulfate) on silica

ABSTRACT The adsorption of an anionic surfactant sodium dodecyl sulfate (SDS) on a negatively charged silica was studied to provide a better understanding of surfactant adsorption phenomena in an electrostatic repulsion environment between surfactant and soil. The adsorption experiment was conducted under different electrolyte concentration and pH. Results indicated that adsorption happened with hydrophobic interaction, although electrostatic repulsion was generated between SDS and silica surface. The adsorption amount decreased with decreasing electrolyte concentration and increasing pH due to the increase of electrostatic repulsion. The influence of electric potential near the silica surface on the adsorption was confirmed with the modified Langmuir adsorption equation, 1-pK basic Stern model and zeta potential. Because silica is ubiquitous in soils and the water environment, the adsorption characteristics of an anionic surfactant is important when we consider the fate of an anionic surfactant in the environment. The result is also useful when considering the fate of agricultural chemicals which contain negative charge and hydrophobic sites.
The Relationship Between Perceived Social Support From Family, Friends, and Significant Others (Nursing Home Staff) and Life Satisfaction Among Elderly Nursing Home Residents

This study examined the relationship between perceived social support from family, friends, and significant others (nursing home staff) and life satisfaction among the residents of a government nursing home for the elderly. Forty-four residents aged between 61 and 74 years from Panti Sosial Tresna Werdha Budi Mulia government nursing home, who were in the young-old developmental stage, participated in this study. These residents were classified as ‘abandoned’ elderly as they either had no family or had families who rarely contacted with them. The Multidimensional Scale of Perceived Social Support (MSPSS) developed by Zimet, Dahlem, Zimet, and Farley (1988) was used to measure perceived social support from family, friends, and significant others, and the Satisfaction with Life Scale (SWLS) developed by Diener, Emmons, Larsen, and Griffin (1985) was used to measure life satisfaction. This quantitative study followed a correlational design. The accidental sampling technique was used, and data analysis was done using the Pearson Correlation Coefficient (p) and Multiple Regression. Our results showed a significant moderate positive correlation between life satisfaction and perceived social support from significant others (nursing home staff) (r = 0.475, p = 0.001) and from family (r = 0.354, p = 0.018). We found no correlation between perceived social support from friends and life satisfaction (r = 0.281, p = 0.065). Future research distinguishing between the elderly who still have families with those who do not would be useful.
RELATION OF MEDICATION ADHERENCE TO THE INCIDENCE OF COMPLICATIONS IN TYPE 2 DIABETES MELLITUS PATIENTS

Objective: The prevalence of diabetes mellitus continues to increase worldwide, followed by the incidence of complications, which ends up causing morbidity and mortality in patients. There were many factors related to the incidence of complications in diabetes mellitus. Patient’s adherence to their medication is considered to have an impact on the complications in diabetic patients. Methods: The study was conducted on 68 patients with a cross-sectional method with consecutive sampling. Statistical analysis was done using the Chi-square and Fisher’s exact test. p<0.05 was considered statistically significant. Patients were interviewed using a demographic data questionnaire and medication adherence rating scale – 5 (MARS-5). Other data and diagnosis of complications were collected through medical records. The epidemiological analysis was carried out using the prevalence ratio. Results: There were 47 (69.1%) patients with type 2 diabetes mellitus (T2DM) hospitalized due to complications, and 56 (82.4%) patients have poor adherence to treatment. There was a significant relationship between treatment adherence and the incidence of complications in diabetes mellitus patients with p = 0.001 and it was found that there was a risk of 3.14 times in patients who have poor adherence to be hospitalized due to complications. Conclusion: Treatment adherence affects the incidence of complications in patients with T2DM.
Serological response and disease-specific neutralizing antibodies in kidney transplant recipients with SARS-CoV-2 infection – a case series

Background Since SARS-CoV-2 is a highly contagious virus without an available disease-specific medication, the hope is focused on a sustained immunity after SARS-CoV-2 infection and a near-term successful vaccination therapy. A sufficient anti-SARS-CoV-2 antibody production with neutralizing antibodies is crucial to prevent further viral spreading and for protection against prospective reinfection. Kidney transplant recipients may have a potentially aggravated risk for COVID-19 complications as well as a reduced vaccine response due to the allograft protecting immunosuppressive therapy. However, little is known about the strength and duration of their immunological response upon SARS-CoV-2 infection.Case presentation Here we report on 4 kidney transplant recipients proven to have SARS-CoV-2 infection by positive PCR testing, focusing on their immunological response with the production of disease-specific neutralizing antibodies. All kidney transplant recipients developed a sufficient antibody response including specific neutralizing antibodies against SARS-CoV-2 within 2 to 3 weeks after the first onset of symptoms that sustained during the follow-up of 15 weeks. After 6 weeks, the virus was eliminated in all patients. Most important, the serological response and viral shedding were achieved and sustained in the presence of immunosuppression. Acute kidney graft deterioration was common but reconstituted in all transplant recipients during follow-up. Conclusions Immunocompromised kidney transplant recipients showed a functional serological response with disease-specific neutralizing antibodies upon SARS-CoV-2 infection, a basic prerequisite for a prospective successful vaccination response.
Carbon monoxide total column retrievals from TROPOMI shortwave infrared measurements

Abstract. The Tropospheric Monitoring Instrument (TROPOMI) spectrometer is the single payload of the Copernicus Sentinel 5 Precursor (S5P) mission. It measures Earth radiance spectra in the shortwave infrared spectral range around 2.3 µm with a dedicated instrument module. These measurements provide carbon monoxide (CO) total column densities over land, which for clear sky conditions are highly sensitive to the tropospheric boundary layer. For cloudy atmospheres over land and ocean, the column sensitivity changes according to the light path through the atmosphere. In this study, we present the physics-based operational S5P algorithm to infer atmospheric CO columns satisfying the envisaged accuracy (
Effect of pre- and postharvest treatments of salicylic and gibberellic acid on ripening and some physicochemical properties of 'Mashhad' sweet cherry (Prunus avium L.) fruit

The effect of pre- and postharvest treatments of salisilic acid (SA) and pre-harvest treatment of gibberellic acid (GA3) on physical and chemical properties, ethylene production and ripening indices of sweet cherry fruit were studied. This experiment was carried out in two sections. In the first experiment, five concentrations of SA including 0, 0.5, 1, 2 and 3 mmol/L were used three weeks before harvest as well as at harvesting time and both timing treatments were combined all in three replicates. In the second experiment, four concentrations of GA3 comprising 0, 10, 20 and 30 mg/L were applied in three replicates. Fruits were sprayed three weeks before harvest when their color started to change from green to yellow. Some fruit quality attributes including ethylene production, flesh firmness, soluble solids concentrations, total acidity, weight and size of fruits were measured immediately after harvest. These measurements were repeated at 7, 14, 21, 28 and 35 days after storing fruits in cold temperature. Statistical analysis showed that, GA3 treatment significantly delayed fruit ripening while increased fruit size. Ethylene production, flesh softening, weight loss, stem browning, PH and fungal rot of fruits decreased by GA3 treatment but anthocyanine content and total acidity of fruits increased, so that, 10 mg/L GA3 caused higher fruit firmness and lower fungal infection. Anthocyanine content, flesh firmness, total acidity and stem freshness of fruits were significantly increased with application of SA, but ethylene production, PH and fungal infection were reduced. In terms of application times, combining pre- and postharvest treatments was the most effective one when 2 and 3 milmol/L SA were used. Both gibberellic acid and salicylic acid treatments kept fruit quality but SA was more effective in decreasing ethylene production and prolonging stem green color compared with the GA3 treatments.
Svan Funeral Dirges (Zär): Musical Acoustical Analysis of a New Collection of Field Recordings

This paper is a companion paper to Mzhavanadze & Scherbaum (2020). Jointly, the two papers describe the results of an interdisciplinary study of three-voiced Svan funeral dirges, known as zär in Svan and zari in Georgian. In the present paper, to which we refer as paper 1, we analyze the musical acoustical properties of a new set of field recordings collected during an ethnomusicological field expedition to Georgia in 2016. The aim of the study is to investigate the tonal organization of eleven different performances of six different variants of zär, performed by singers from different villages. For some of the performances, we observe a strong gradual pitch rise of up to 100 cents per minute. The intra-variant differences in the performances of different groups of singers were observed to be remarkably different, including the use of significantly different harmonic tuning systems. In contrast, two subsequent performances of the Mest’ia variant of zär by a group of singers recorded in Zargǟsh were essentially identical. This demonstrates the widespread absence of improvisational elements in these two performances. One of the most interesting results of our analysis is the observation that the musical structure of zär, expressed, for example, in its ambitus, the complexity of its melodic progression, and its harmonic chord inventory, change systematically along the course of the Enguri valley.
Structural and Dynamical Properties of a Deep Eutectic Solvent Confined Inside a Slit Pore

We performed molecular dynamics (MD) simulations to study the structure and dynamics of the deep eutectic solvent (DES) choline iodide-glycerol (CI.G) at a molar ratio of 1:3, inside slitlike titania [rutile (110)] and graphitic nanopores of width H = 5.2 and 2.5 nm, and at a temperature T = 333 K. DESs share many of the remarkable properties of ionic liquids (ILs) while being more inexpensive; furthermore, and in addition to their fundamental scientific interest, the systems modeled here are relevant to dye-sensitized solar cells and gas separations. Our results show that glycerol can form stable hydrogen bonds with the oxygen atoms in the rutile walls, which account for ∼86% of the total number of hydrogen bonds involving DES species (choline, iodide, and glycerol) in the first layers (near the rutile walls), and for ∼24% of the total hydrogen bonds observed for the DES inside a rutile pore of width H = 5.2 nm. As a result, in these systems, the rutile walls are coated by glycerol layers that are almost.

Hybrid magnetic elastomers prepared on the basis of a SIEL-grade resin and their magnetic and rheological properties

Abstract Hybrid magnetic elastomers (HMEs) belong to a novel type of magnetocontrollable elastic materials capable of demonstrating extensive variations of their parameters under the influence of magnetic fields. Like all cognate materials, HMEs are based on deformable polymer filled with a mixed or modified powder. The complex of properties possessed by the composite is a reflection of interactions occurring between the polymer matrix and the particles also participating in interactions among themselves. For example, introduction of magnetically hard components into the formula results in the origination of a number of significantly different behavioral features entirely unknown to magnetorheological composites of the classic type. Optical observation of samples based on magnetically hard filler gave the opportunity to establish that initial magnetization imparts magnetic moments to initially unmagnetized grains, as a result of which chain-like structures continue to be a feature of the material even after external field removal. In addition, applying a reverse field causes them to turn into the polymer as they rearrange into new ring-like structures. Exploration of the relationship between the rheological properties and magnetic field conducted on a rheometer using vibrational mechanical analysis showed an increase of the relative elastic modulus by more than two orders of magnitude or by 3.8 MPa, whereas the loss factor exhibited steady growth with the field up to a value of 0.7 being significantly higher than that demonstrated by elastomers with no magnetically hard particles. At the same time, measuring the electroconductivity of elastomers filled with a nickel-electroplated carbonyl iron powder made it possible to observe that such composites demonstrated an increase of variation of the resistivity of the composite influenced by magnetic field in comparison to elastomers containing untreated iron particles. The studies conducted indicate that this material exhibits both magnetorheological and magnetoresistive effect and does indeed have the potential for use in various types of devices.
DETAILED CHEMISTRY, SOOT, AND RADIATION CALCULATIONS IN TURBULENT REACTING FLOWS

The present work aims at a comprehensive approach for the simulation of turbulent reacting flows. In particular, it focuses on the modeling of detailed chemistry, detailed soot formation and oxidation, and the modeling of detailed radiative heat transfer in gas-phase turbulent flames. In addition, the present work centers on numerical investigations of oxygen-enriched turbulent nonpremixed flames. Issues that arise in calculating detailed chemistry, soot formation and oxidation, and thermal radiation in turbulent reacting flows are reviewed and discussed. Two detailed models of turbulent combustion are developed using state-of-the-art models of detailed chemistry, soot, and radiation calculations in turbulent flames. One of the models is based on an empirical description of the turbulent flow field and the other is based on CFD modeling of the flow field. The empirical-description-based model is an extension of Two-Stage Lagrangian (TSL) model of turbulent jet flames. This extension includes the incorporation of a detailed soot model and the improvement of the radiation model. The soot model is a detailed one adopted from Appel-Bockhorn-Frenklach’s soot model. The dynamics of soot particles are described by the method of moments adapted to the TSL formulation. The original constant-emissivity radiation model is improved by solving the radiative transfer equation on the spatial configuration of the TSL model using the spherical harmonic P1 method and the discrete ordinate S2 method. The gray medium assumption is employed and the Planck-mean absorption coefficient is used to determine the radiative properties of both gas-phase species and soot particles. With the extended TSL model, the characteristics of soot, radiation and NOx emissions in oxygen-enriched flames are studied. The CFD-based model is based on an engineering CFD code (GMTEC) and it solves the compressible flow equations on unstructured meshes. GMTEC is extended by incorporating a detailed chemistry model, a detailed soot model, and a detailed radiation model. The detailed chemistry model is based on the use of the CHEMKIN libraries,

The Transportation Infrastructure and Regional Economic Growth—Evidence from Dongguan Humen Bridge

Transportation infrastructure is an important factor driving regional economic growth, and scientifically evaluating the economic growth effects of key transportation infrastructure is an important theoretical issue of development economics. This paper takes the opening of Dongguan Humen Bridge as a quasi-natural experiment, and quantitatively identifies the regional growth effect it brings. This paper uses panel data from 21 prefecture-level cities in Guangdong Province from 1991 to 2007, and based on the synthetic control method, assigns different weights to the cities in the control group to construct the “counterfactual” state of Dongguan where the Humen Bridge is not opened, so as to compare the difference in economic development between “real Dongguan City” and “Synthetic Dongguan City”. The results show that the opening of the Humen Bridge in 1997 made Dongguan’s GDP and GDP per capita exceed the theoretical level that could be achieved when the Humen Bridge was not opened. The opening of the Humen Bridge significantly changed the economic growth trend of Dongguan. With the passage of time, the opening of the Humen Bridge has continuously strengthened the promotion of Dongguan’s economic growth, indicating that the transportation infrastructure has a long-term effect on the promotion of regional economic growth. This work advances the research on the relationship between transportation infrastructure and regional economic growth.
Impacts of Fertigation via Surface and Subsurface Drip Irrigation on Growth Rate of Rockmelon

Fertigation is one of the most important application of irrigation that are being used in commercial farming. This aplication help farmers to timely supply the water through drip irrigation coupled with accurate amout of water, rate of fertilizer application, and at the same time improving the nutrient uptake and water use efficiency (WUE) by the plant. The water supply through surface and subsurface drip irrigation system is the most efficient irrigation practice compared to others.Water supply from subsurface drip irrigation system is directly into the root zone, while for surface drip irrigation, water is supplied above the root zone. However, the use of surface drip irrigation system can cause the irrigation water easily evaporate to environment and reduce the WUE by plant. Rockmelon (cucumis melo) was selected as plant material in this study. Rockmelon is one of the plant that contain sweet and juicy along with other nutritional value. It also has commercial interest in a number of countries, including Europe, the United States, Mediterranean and Asia. The objectives of the study were to observe the different growth rate of rockmelon between surface and subsurface drip irrigation as well as to observe the efficiency of irrigation. This study was conducted under the rain shelter at Unit Fertigasi Projek Keusahawanan Ladang 10, Universiti Putra Malaysia (UPM). There were two treatments of irrigation tested, surface drip irrigation and subsurface drip irrigation. Data collection include leaf diameter, leaf length and fruit circumferences. The effect of irrigation on growth performance of rockmelon were observe during week one and week six and was analyzed with Statistically Analysis System (SAS). The result of this study showed that, the growth for surface drip irrigation is higher compared to subsurface drip irrigation and both of the treatments achieved 25% of irrigation application efficiency.
Suitable Definition of Drift Mobility

Measurement of the drift mobility defined as the proportionality constant of the mean velocity (υ) to the electric field strength (E) is necessary for understanding of carrier transport. However, it is difficult to obtain v from the time-of-flight transients. Thus the velocity obtained from the transit time has been analyzed instead of the mean velocity. The most common measurement ofthe mobility (μ k-ex ) is obtained from the time derived from the intersection of the asymptotes to the plateau and tail of the transients. Because the long tail of photocurrent transients for molecularly doped polymers indicates anomalous dispersion of carrier transit times, the difference between υ/E and μ k-ex is not negligible. Recently, a theoretical photocurrent transients equation (PTE) has been introduced. Fitting of the PTE to nondispersive transients gives the values of υ and the diffusion coefficient (D) simultaneously. In this article, using the PTE, both the mobility (μ k-cal ), obtained from a kink in the photocurrent transient, and the tail-broadening parameter (W cal ) were derived as functions of υ, D and sample thickness. We have tried to explain the anomalous behavior of μ k-ex and the tail-broadening parameter (W ex ) in order to verify the PTE. The dependences of μ k-ex and W cal on the electric field and the sample thickness satisfactory agreed with those of μ k-ex and W ex . These verify the PTE and suggest that fitting of the PTE to photocurrent transients is suitable way to obtain the drift mobility.
