Evaluation of Children with Nephrotic Syndrome: A Single- Center Experience

Objective: Nephrotic syndrome (NS) is one of the most frequent occurring chronic kidney diseases in children. In this study, our aim was to assess the sociodemographic structure, determination of clinical data, diagnostic approaches, treatment methods applied and the factors effective on prognosis in patients followed with a diagnosis of nephrotic syndrome in our clinic. Method: The files of 256 patients diagnosed with primary nephrotic syndrome between the ages of 0 and 18 who were followed in Department of Pediatric Nephrology during a period of 15 years between 2004 and 2019 were examined retrospectively. 220 patients whose data were sufficient and who had a sufficient follow-up time were included in the study. Results: 137 of our patients were male, 83 were female and the ratio of male/female was 1.65. Average onset age of the cases was 4.8 ± 2.6 years (1 months-16 years). Renal disease history in the family was 16.4% and the rate of consanguineous marriage was 25.9%. 24% of our patients were found to have microscopic hematuria, 28.2% were found to have hypertension. Of the patients who received biopsy, 32 were determined as FSGS, 18 as MCD, 11 as MPGN, 3 as IgM nephropathy, 2 as hereditary nephrite, 2 as MezPGN, 1 as MGN, 1 as congenital NS and 2 as other reasons. While a total of 193 patients (87.7%) were sensitive to steroid, 27 patients (12.2%) were found to be resistant to steroid. While 78 (35.5%) of the patients were followed with no relapse, 120 (54.5%) patients were relapsing and 22 (10%) patients had frequent relapses. In their follow-up, mortality rate of our patients was found as 2.7%. Conclusion: With this study, we assessed children with primary nephrotic syndrome in our area comprehensively for the first time. Consanguineous marriage rate was higher in our patients. Our findings were also remarkable in terms of demonstrating that primary NS follows its own course in each child depending on the underlying genetic structure.
The Herbicidal Potential of Different Pelargonic Acid Products and Essential Oils against Several Important Weed Species

There is growing consideration among farmers and researchers regarding the development of natural herbicides providing sufficient levels of weed control. The aim of the present study was to compare the efficacy of four different pelargonic acid products, three essential oils and two natural products’ mixtures against L. rigidum Gaud. , A. sterilis L. and G. aparine L. Regarding grass weeds, it was noticed at 7 days after treatment that PA3 treatment (pelargonic acid 3.102% w/v + maleic hydrazide 0.459% w/v) was the least efficient treatment against L. rigidum and A. sterilis. The mixture of lemongrass oil and pelargonic acid resulted in 77% lower dry weight for L. rigidum in comparison to the control. Biomass reduction reached the level of 90% as compared to the control in the case of manuka oil and the efficacy of manuka oil and pelargonic acid mixture was similar. For sterile oat, weed biomass was recorded between 31% and 33% of the control for lemongrass oil, pine oil, PA1 (pelargonic acid 18.67% + maleic hydrazide 3%) and PA4 (pelargonic acid 18.67%) treatments. In addition, the mixture of manuka oil and pelargonic acid reduced weed biomass by 96% as compared to the control. Regarding the broadleaf species G. aparine, PA4 and PA1 treatments provided a 96–97% dry weight reduction compared to the corresponding value recorded for the untreated plants. PA2 (pelargonic acid 50% w/v) treatment and the mixture of manuka oil and pelargonic acid completely eliminated cleaver plants. The observations made for weed dry weight on the species level were similar to those made regarding plant height values recorded for each species. Further research is needed to study more natural substances and optimize the use of natural herbicides as well as natural herbicides’ mixtures in weed management strategies under different soil and climatic conditions.
Forging asteroid-meteorite relationships through reflectance spectroscopy

Near-infrared spectra were obtained for 196 asteroids as part of SMASSIR. SMASSIR focused on observing asteroids assumed to be one of the following: (1) olivine-rich, (2) objects with "Vesta-like spectra" (the "Vestoids"), and (3) postulated meteorite parent bodies.
First Principle Investigation of Electronic, Transport, and Bulk Properties of Zinc-Blende Magnesium Sulfide

We have studied electronic, structural, and transport properties of zinc-blende magnesium sulfide (zb-MgS). We employed a local density approximation (LDA) potential and the linear combination of atomic orbitals (LCAO) method. Our computational method is able to reach the ground state of a material, as dictated by the second theorem of density functional theory (DFT). Consequently, our findings have the physical content of DFT and agree with available, corresponding experimental ones. The calculated band gap of zb-MgS, a direct gap equal to 4.43 eV, obtained at the experimental lattice constant of 5.620 Å, completely agrees with the experimental band gap of 4.45 ± 0.2 eV. We also report total (DOS) and partial (pDOS) densities of states, electron and hole effective masses, the equilibrium lattice constant, and the bulk modulus. The calculated pDOS also agree with the experiment for the description of the states at the top and the bottom of the valence and conduction bands, respectively.
Interplay of tectonics and magmatism during post‐rift inversion on the central West Iberian Margin (Estremadura Spur)

The combined effects of post‐rift magma emplacement and tectonic inversion on the hyper‐extended West Iberian Margin are unravelled in detail using multichannel 2D/3D seismic data. The Estremadura Spur, acting as an uplifted crustal block bounded by two first‐order transfer zones, shows evidence of four post‐rift tectonic events each with a distinctive seismic‐stratigraphic response that can be used to demonstrate the tectono‐magmatic interplay, namely: (a) the Campanian onset of magmatism (including the Fontanelas Volcano, the widespread evidence of multiple sill complexes and the detailed description of a >20 km long laccolith, the Estremadura Spur Intrusion; (b) the Campanian‐Maastrichtian NE‐SW event pervasively affecting the area, resulting in regional uplift, reverse faulting and folding; (c) the Paleocene‐mid Eocene inversion that resulted in widespread erosion and; (d) the Oligocene‐mid Miocene evidence of rejuvenated NW‐SE inversion marked by crestal faulting and forced‐fault folding establishing the final geometry of the area. The distinct deformation styles within each tectonic phase document a case of decoupled deformation between Late Cretaceous and Tertiary units, in response to the predominant stress field evolution, revealing that the magnitude of Late Cretaceous inversion is far more significant than the one affecting the latter units. A detailed analysis of the laccolith and its overburden demonstrate the distinct deformation patterns associated both with magma ascent (including extensional faulting, forced‐folding and concentric reverse faulting) and its interference as a rigid intrusive body during subsequent transpressive inversion. This reinforces the role that the combined tectono‐magmatic events played on the margin. Also analysed is the wider impact of post‐rift magmatism and the associate emplacement of sub‐lithospheric magma on the rheology of a thinned continental crust. This takes into account the simultaneous tectonic inversion of the margin, the implied alternative views on characteristic heat flow, and on how these can be incorporated in source rock organic maturity modelling.
Applicability Evaluation of Nile Blue A Dye to Korean Termite (Reticulitermes speratus kyushuensis)

Dye markers are used in the study of subterranean termites to determine colony territories and population sizes. Dyes not only allow the study of termite biology, but can also be used for control purposes. Although Reticulitermes speratus kyushuensis causes damage to wooden historical properties in Korea, the dye markers have not been applied. Therefore, we evaluated the applicability of Nile Blue A dye for R. s. kyushuensis. Filter papers dyed with concentrations of 0.05%, 0.10%, and 0.25% (w/w) were each fed to termite populations through a no-choice feeding test for 1, 3, or 7 days. After 4 weeks, the survival rate, dyeing rate, and maintenance of dyeing were recorded. The results showed high survival rates with lower dye concentrations and shorter feeding periods. Among the combinations of concentrations and days, high survival rates, dyeing rates, and dyeing maintenance periods were found at concentrations of 0.05% and 0.10% for 3 days of feeding. These maximized the survivorship and visibility. The results from the current study can be applied to investigate the ecology and control of R. s. kyushuensis in both the laboratory and field.
Seismic codes based equivalent nonlinear and stochastic soil structure interaction analysis

Abstract The aim of this study is to consider the effects of the variation of shear modulus ratio (G/G0) and damping ratio (ξ) of soil, obtained by a linear iterative method based on the design spectra of seismic codes, the soil environment in terms of uncertainties in shear modulus using Monte Carlo simulations and the foundation damping (ξf) of flexible base for analyses of the Soil-Structure Interaction (SSI) problems. A squat structure with circular shallow foundation resting on a soil layer over a homogeneous half-space is studied by using cone model and considering seismic zone effect on structural response. Firstly, after showing the effects of the correction of G and ξ on impedance functions and the responses of soil-foundation-structure system, a study is carried out to compare these effects to those of the modelling of uncertainties in shear modulus as random variations. Secondly, a comparative analysis on design response spectra and base shear forces was carried out for four seismic codes (Algerian Seismic Rules RPA99-2003, Eurocode 8–2004, International Building Code IBC-2015 and Indian Code IS-1893-2002) considering the three cases of SSI: SSI effects (initial G and ξ), nonlinear SSI (corrected G and ξ) and stochastic SSI (random G with COV = 20%) compared to the fixed base case. Results show that the correction of G and ξ, according to the equivalent nonlinear method in all the cases, leads to a remarkable decrease in peak responses but show a huge amount of reduction in the second study for IBC-2015 and IS-1893-2002 codes compared to the other codes.
Constraining Uncertainty in Projected Gross Primary Production With Machine Learning

The terrestrial biosphere is currently slowing down global warming by absorbing about 30% of human emissions of carbon dioxide (CO2). The largest flux of the terrestrial carbon uptake is gross primary production (GPP) defined as the production of carbohydrates by photosynthesis. Elevated atmospheric CO2 concentration is expected to increase GPP (“CO2 fertilization effect”). However, Earth system models (ESMs) exhibit a large range in simulated GPP projections. In this study, we combine an existing emergent constraint on CO2 fertilization with a machine learning approach to constrain the spatial variations of multimodel GPP projections. In a first step, we use observed changes in the CO2 seasonal cycle at Cape Kumukahi to constrain the global mean GPP at the end of the 21st century (2091–2100) in Representative Concentration Pathway 8.5 simulations with ESMs participating in the Coupled Model Intercomparison Project Phase 5 (CMIP5) to 171 ± 12 Gt C yr−1, compared to the unconstrained model range of 156–247 Gt C yr−1. In a second step, we use a machine learning model to constrain gridded future absolute GPP and gridded fractional GPP change in two independent approaches. For this, observational data are fed into the machine learning algorithm that has been trained on CMIP5 data to learn relationships between present‐day physically relevant diagnostics and the target variable. In a leave‐one‐model‐out cross‐validation approach, the machine learning model shows superior performance to the CMIP5 ensemble mean. Our approach predicts an increased GPP change in northern high latitudes compared to regions closer to the equator.
Wheat straw mulch improves summer maize productivity and soil properties

Crop residue mulch in agricultural systems preserves soil health and improves crop productivity through its moderating influence on soil temperature regime and enhanced moisture retention. Therefore, a field experiment was conducted to determine the changes in soil properties and grain yield of irrigated summer maize in response to wheat straw mulching in the Northern maize region in China. The treatments investigated were: i) application of wheat straw mulch (5000 kg ha–1); and ii) no-mulch application (control). Maize growth and yield attributes were determined during various growth stages, and soil hydro-thermal properties were recorded for two depths (0-15 and 15-30 cm). Straw mulch increased the yield by 18% and also increased total dry biomass yield by 20%, compared to no-mulch. Yield increment was attributed to the increased number of ears per area and kernels number per ear. The effect on thousand kernels weight was found non-significant. Vigorous maize growth was observed under straw mulch treatment, having greater leaf area index, unit leaf rate, leaf area duration, and crop growth rate. Similarly, the dry matter partitioning for maize kernels was greater in mulch treatment. At the late reproductive stages (R3 and R5), SPAD values for ear and below-ear leaves were higher under mulch treatment. Straw mulch decreased the daytime soil temperature by 1.9 and 1.5°C on average for 0-15 and 15-30 cm soil layers, respectively. Whereas, the soil moisture content increased about 2.5% (0-15 cm) and 3% (1530 cm) under the mulch treatment. In crux, leftover crop residue application as mulch in irrigated maize could be a sustainable agronomic option to increase the crop productivity.
The Reciprocal Role of Trust in Customer Value Co-Creation

The main purpose of this research was to investigate the reciprocal nature of trust in a service provider, established through consumer involvement in value co-creation. Grounded in service-dominant logic and social exchange theory, the study used an existing consumer-generated co-creation contest by a popular U.S.-based coffee-shop brand. When examining customer involvement with value co-creation (N = 510), the covariance-based structural equation model test of recursive versus sequential trust models revealed that trust served as both a significant antecedent and an outcome of value co-creation and is reciprocal in nature. The findings provide support for trust networks as necessary condition for successful value co-creation. Finally, theoretical implications for service-dominant logic and social exchange theory are presented and practical implications discussed.
Patterns of Energy Consumption in Polish One-Person Households

Poland belongs to a group of countries with the highest share of expenditure on energy carriers in total household expenditure among the EU-28 countries. This fact adversely affects the quality of life of Polish citizens. One of the types of households which are most severely burdened with expenditure on energy carriers are households run by a single person. The scientific objective of the study was to identify the consumption patterns of energy carriers in Polish one-person households. The findings of the research were used to assess the correlation between the risk of energy poverty and particular socio-economic and demographic characteristics of the representatives of these households. Many statistical methods were used to achieve the research goal: analysis of variance, regression analysis, and cluster analysis. An aggregated index of energy comfort has been designed. Social factors, such as the level of education and the fact of holding non-manual positions, are strongly related to the level of expenditure on energy carriers and the degree of satisfaction of the needs related to the thermal comfort. The types of one-person households particularly vulnerable to energy poverty were individuals who had a number of different characteristics. The group included individuals who were unemployed, disabled, with low disposable income, with a low education level, living in the rural areas as well as elderly people. Polish one-person households can be divided into four groups according to the expenditure on energy carriers and meeting their needs related to thermal comfort.
A Study of Moroccan Rosemary Oils

Abstract The chemotaxonomy of Moroccan rosemary was studied. The essential oil, which was obtained by hydrodistillation of Rosmarinus officinalis L. from different regions of Morocco (Rabat, Taforalt and Elateuf) was analyzed by GC and GC/MS. The variations in chemical composition are important between plant populations. We have defined three chemotypes of R. officinalis: the α-pinene-chemotype (α-pinene, 37–40% of the oil), the camphor-chemotype (camphor, 41–53% of the oil) and the 1,8-cineole-chemotype (1,8-cineole, 58–63% of the oil). The chemical composition of the 1,8-cineole-chemotype of R. officinalis was analyzed by GC and GC/MS. A total of 91 constituents were identified. The effect of harvest time on the oil production and chemical composition was examined on R. officinalis, and R. eriocalyx Jordan et Fourr. , which were collected in the eastern Morocco from Elateuf and Debdou regions at different vegetative stages (from January to July). At full flowering, the oil yield was particularly high (1.6 % for R. officinalis and 1.9 % for R. eriocalyx). It was much lower for early or late flowering. The chemical composition of oils does not seem to be a function of the species differentiation or harvest time. 1,8-Cineole (48,9–56,3%) was the main component of the oils of both species.
1D and 2D NMR spectra of coffee from 27 countries

Between 2012 and 2014, 715 green coffee samples were gathered by Almacafé S.A. (Bogotá, Colombia) from 27 countries. These were analysed at the nuclear magnetic resonance (NMR) laboratory at Universidad del Valle (Cali, Colombia). Over 1000 methanolic coffee extracts were prepared and 4563 spectra were acquired in a fully automatic manner using a 400 ﻿MHz NMR spectrometer (Bruker Biospin, Germany). The dataset spans the variance that could be expected for an industrial application of origin monitoring, including samples from different harvest times, collected over several years, and processed by at least two distinct operators. The resulting 1D and 2D spectra can be used to develop and evaluate feature extraction methods, multivariate algorithms, and automation monitoring techniques. They can also be used as datasets for teaching, or as a reference for new studies of similar samples and approaches.
Company capital structure’s theoretical framework: historical assessment and trends in the 21st century

Company capital is essential in running business and creating value added for the stakeholders, including economy. How the view on company’s capital structure has evolved from theoretical perspective in the 20th century is needed to be assessed, in order to determine what concepts and theories, if any are relevant in the 21st century. Many theories have competed their way and transformed during the 20th century, while some, i.e. trade-off, signalling and stakeholder theories are still relevant in the 21st century. There are also new trends in the 21st century, new terms and quests shifting from determining and analysing optimal company’s capital structure to sustainable finance, taxonomy and also sustainability in capital structure. Therefore, the aim of this research: to establish existing main theories impacting and analysing company’s capital structure and to examine the theoretical shift of the theories based on the needs in the 21st century. Authors defined company’s capital structure and determined that during the years 1989–2020, number of research publications has grown significantly, thus validating the need to reassess theoretical background of capital structure theories in the 20th century, as well as to help to determine the trends still relative and emerging from the theoretical and practical aspects to company’s capital structure in the 21st century.
Study of the structure and deviation from equilibrium in direct current supersonic plasma jets

Mathematical modelling and optical emission spectroscopy are applied to study the effect of the chamber pressure on the structure and properties of supersonic plasma jets formed by a direct current arc. In this installation the plasma is created inside the nozzle where the flow is accelerated. As a result some deviation from thermal and ionization equilibrium can be found, even at the working chamber inlet. In this paper, by means of a two-temperature model, we study the argon jet flow using the data of the emission spectroscopy measurements to make realistic assumptions about the inlet boundary conditions. The results show that, when the chamber pressure is low, a strongly underexpanded jet with a Mach disc is formed. For the higher ambient pressure values, the core region of the jet changes to a mildly underexpanded structure with alternating oblique expansion and compression zones. The predicted shock zone positions are in a very good agreement with measurement. The general analysis shows that the deviation from local thermodynamic equilibrium in the jet is inversely related to the chamber pressure. Along the jet core the deviation from thermal equilibrium is less in the shock regions than in the expansion zones, where the electrons are heated by three-particle recombination. Downstream of the jet core the velocity drops, but the ionization and thermal equilibria are not attained because of the correlation between the characteristic recombination and the hydrodynamic times. Both the modelling and the emission spectroscopy show that the axial electron number density is much closer to its frozen value than to equilibrium value. The results obtained are helpful for different applications such as plasma processing, rocket propulsion systems and the simulation of re-entry conditions.
Effect of Drying and Steeping Temperatures on the Phenolic Content, Antioxidant Activity, Aromatic Compounds and Sensory Properties of Cunila polyantha Benth. Infusions

Cunila polyantha Benth. (Lamiaceae), an aromatic plant endemic to Mexico, is used in traditional medicine as tea infusions. In this study, the effects of different drying and steeping temperatures on the phenolic content and composition, antioxidant activity, volatile composition, and sensory properties of C. polyantha infusions were determined. Commercial green tea (Camellia sinensis L. Kuntze) was used as a control. The phenolic compounds identified in the C. polyantha infusions by high-performance liquid chromatography (HPLC) include phenolic acids such as gallic acid, chlorogenic acid, caffeic acid, and p-coumaric acid, flavonoids such as epigallocatechin gallate, protocatechin, quercetin, and naringenin, as well as the phenolic aldehyde vanillin. The C. polyantha infusions showed scavenging activity of DPPH• and ABTS•+ radicals as well as relevant antioxidant capacity, which was dependent on tea preparation conditions. A total of 46 volatile organic compounds (VOCs) were detected from the leaves and flowers of C. polyantha, while in the control group, a total of 30 VOCs were identified. Differences in consumer acceptability of C. polyantha infusions prepared at different conditions were observed. This research highlights the importance of linking sensory and chemical data to obtain the best sensorial quality and the optimal nutraceutical properties in C. polyantha infusions.
