Published: September 2021

Background: The development of superior hybrids is must to break the existing yield plateau ( less than 800 kg/ha) in pigeonpea and hence, the genetic mechanism governing the heterosis in pigeonpea must be decoded. Methods: The present study was laid down using randomized block design during kharif 2018-19 at GBPUAT, Pantnagar with 36 genotypes (8 parents and 28 F1 hybrids) of pigeonpea. The estimates of combining ability were evaluated by using the Griffing’s, Method II, Model I. The observations recorded for yield and related traits were subjected to the estimation of genetic diversity (GD) using the D2 statistics. The correlation between heterosis and different parameters viz., parental mean (PM), specific combining ability (SCA), mean of general combining ability (MGCA) and genetic diversity (GD) were estimated by using Pearson’s correlation. Result: High estimates of SCA variance and more than unity ( greater than 1) average degree of dominance for all the characters indicated the presence of over dominance. The SCA followed by MGCA were found to be most reliable parameters to predict the heterosis. The parents having high x low or high x high per se performance, good x poor GCA effects and with medium genetic diversity resulted in high frequency of heterotic hybrids.
Attracting sets for one class of asymptotically compact systems with pulsed perturbation
Authors: Kapustyan Oleksiy , Gorban Nataliia 
Published: September 2021

The authors consider the pulsed dynamical systems generated by evolutionary processes. The trajectories of these processes undergo the pulsed perturbation when the energy functional reaches some fixed limit value. The generalization of the classical theory of global attractors of infinite dimensional dynamical systems in case of systems with impulse actions is carried out. It is established that for the dissipative pulsed dynamical system generated by the asymptotically compact semigroup, there exists a uniform attractor, i.e., a compact uniformly attracting set, minimal among all such sets in the phase space of the system. The result is applied to the weakly nonlinear wave equation with dissipation, the trajectories of which are subjected to impulsive perturbations upon attainment of a certain fixed subset in the phase space, so called the impulse set.

An Adaptive Sequential Fully Implicit Domain-Decomposition Solver

Published: September 2021

SummaryModern reservoir simulation must handle complex compositional fluid behavior, orders-of-magnitude variations in rock properties, and large velocity contrasts. We investigate how one can use nonlinear domain-decomposition preconditioning to combine sequential and fully implicit (FI) solution strategies to devise robust and highly efficient nonlinear solvers. A full simulation model can be split into smaller subdomains that each can be solved independently, treating variables in all other subdomains as fixed. In subdomains with weaker coupling between flow and transport, we use a sequential fully implicit (SFI) solution strategy, whereas regions with stronger coupling are solved with an FI method. Convergence to the FI solution is ensured by a global update that efficiently resolves long-range interactions across subdomains. The result is a solution strategy that combines the efficiency of SFI and its ability to use specialized solvers for flow and transport with the robustness and correctness of FI. We demonstrate the efficacy of the proposed method through a range of test cases, including both contrived setups to test nonlinear solver performance and realistic field models with complex geology and fluid physics. For each case, we compare the results with those obtained using standard FI and SFI solvers.NOTE: This paper is also published as part of the 2021 SPE Reservoir Simulation Conference Special Issue.

Published: September 2021

Summary
We introduce a quick and cost-effective method of estimating horizontal in-situ stress profiles and rock elastic moduli vs. depth from geophysical logs taken in vertical well sections. A multiobjective optimization approach finds the optimum solution for the inversion of in-situ stresses and the rock mechanical parameters from elastic borehole deformations measured by the commonly available four-arm caliper tools. The four-arm caliper log responses also permit quality control (QC) of input and identification and classification of borehole sections that display breakouts and sloughing. The method is applied in the estimation of horizontal in-situ stress profiles and rock deformation moduli vs. depth in Karamay Basin, Northwestern China. The results have demonstrated good agreement with available field in-situ stress measurements, indicating promising broader applications of the method.

Published: September 2021

Abstract
Objective: To evaluate the relationship between the endometrial features (endometrial thickness(EMT), pattern and endometrium growth amplitude and rate) and the embryo stage transferred and ectopic pregnancy after IVF-ET based on the data of 628 matched cases. Methods: This was a 1:1 matched case-control study that enrolled 314 EP patients and 314 matched IUP patients from the ART center of Xiangya Hospital of Central South University from January 2014 to April 2020. Univariate analysis and multiple-stepwise logistic regression analysis was used to analyze the risk factors of EP, and a receiver-operating characteristic (ROC) curve was generated to predict EP. Results: 1. The EP group had a higher cleavage stage embryo transfer rate(94.57% vs 86.22%), a thinner endometrium on transformation day (the day when progesterone was added in the frozen embryo cycle or the trigger day in the fresh embryo cycle) (9.40(2.60) mm vs 9.80(2.60)mm) compared with IUP group. In fresh embryo cycles, the EP group had a higher endometrium pattern C proportion on transformation day, a smaller endometrium increment, and a slower endometrial growth rate compared with the IUP group. 2.The ROC curves were used to analyze the cut-off values of the EMT on transformation day, the endometrial growth amplitude and rate in fresh cycles, the results were 9.35mm, 4.90mm and 0.491 mm/d, respectively. The incidence of EP was significantly different between groups according to cut-off values. 3. The transferred embryo stage and EMT on transformation day were independent factors affecting outcome in the general population. The area under the curve(AUC) of the EMT and the stage of embryos transferred for EP prediction was 0.604, sensitivity was 0.702, and specificity was 0.465. The EMT on trigger day was an independent factor affecting outcome in the fresh cycles. The AUC of the EMT for EP prediction in fresh cycles was 0.605, sensitivity was 0.805, and specificity was 0.420. Conclusions: 1. Transferring cleavage stage embryo , and thin EMT on the transformation day were risk factors for EP. 2. Thin EMT and pattern C on transformation day may be related to abnormal endometrial receptivity and endometrial peristaltic waves. 3.The combined indicator of EMT and embryonic development stage could not well predict the occurrence of EP after ET.

Published: September 2021

Abstract
This study investigated the characteristics of the proliferation process of Microcystis aeruginosa and its changes to environmental pH values under different initial pH values and different initial inoculation densities. The results showed that although the initial pH value or the initial inoculation density was different, the pH values of the culture systems fluctuated up and down throughout the proliferation of M. aeruginosa, both on a daily and hourly time scale, and then tended to stabilize around the same value of 10.0 at the end of proliferation. The optimal pH value for the proliferation of M. aeruginosa was 9.56. This study creatively proposes that the period when the environmental pH value starts to rise rapidly toward 9.0 could be selected as an early warning period for a cyanobacterial outbreak, and the environmental pH value could be adjusted to below 8.0 to delay the outbreak. These results provide a scientific basis for further understanding the mechanism of cyanobacterial blooms and formulating pH-based control strategies.

Published: September 2021

Abstract
Experimental analysis of viscosity can be a straightforward and inexpensive analysis for few samples. However, in industrial processes that have high demands of properties measurements, the determination of viscosity and other properties involves time-consuming with sampling, analysis and availability of results. Also in refineries, the sampling routines for experimental determination of the viscosity of streams are not enough to represent variations that occur in the process, such as the shift of an oil tank in distillation units. In addition, besides requiring cost of operating personnel and laboratory analyst, all of these steps can take up to one shift until the result is available. Therefore, as an alternative, the use of predictive methods of kinematic viscosity are essential. Empirical methods have been used in simulations and design calculations of streams and mixture at industries regarding kinematic viscosity (KV) of petroleum fractions and fuels at different temperatures. However, there are uncertainties about the most accurate method to use at specific condition (temperature, feedstock, volume fraction) which might affect the KV prediction of fuels with unknown composition. Therefore, we assembled and evaluated several methods to predict KV of different diesel systems. In addition, new methods for predicting KV of diesel fractions at several temperatures were also developed for improving the estimation accuracy. As a result, we developed a guide with suggestions of the most accurate models to be applied for diesel fraction from assays, diesel fractions S500 from blend system at several temperatures, and biodiesel-diesel blends at different temperatures, volume fractions and feedstock.

Published: September 2021

Abstract
Background: Air pollution exposure has been associated with a multitude of diseases and poses a significant concern to public health. For targeted environmental risk communication and interventions to be effective, it is important to correctly identify characteristics associated with worry of harm from air pollution. Methods: Using responses from 3,630 participants of the Health Information National Trends Survey 4 Cycle 2, we assessed worry of harm from exposure to indoor (IAP) and outdoor (OAP) air pollution separately. Multinomial logistic regression models were used to calculate odds ratios and 95% confidence intervals. Results: Hispanics were more likely to worry about harm from IAP and OAP compared to non-Hispanic whites. Participants who lived in urban counties were more likely to worry about harm from IAP and OAP compared to those who lived in rural counties. Finally, those who believed their chance of getting cancer was high were more likely to worry about harm from IAP and OAP compared to those who thought their likelihood of getting cancer was low. Conclusions: Worry of harm from IAP and OAP varied across sociodemographic and cancer-related characteristics. Public health professionals should consider these characteristics when developing targeted environmental risk communication and interventions.

Published: September 2021

Abstract
The possibility of rapid estimation of moisture, protein, fat, free fatty acid (FFA), and peroxide value (PV) content in peanut kernel was studied by Fourier transform near-infrared spectroscopy (FTNIR) in the diffuse reflectance mode along with chemometric technic. The moisture, fat and protein of fresh and damaged seeds of peanuts ranging from 3 to 9 %, 45 to 57 % and 23 to 27 % respectively, were used for the calibration model building based on partial least squares (PLS) regression. The peanut samples had major peaks at wavenumbers 53.0853, 4954.98, 4464.03, 4070.85, 74.75.63, 8230.21, and 6178.13 in per cm. First and second derivate mathematical preprocessing was also applied in order to eliminate multiple baselines for different chemical quality parameters of peanut. The FFA had the lowest value of calibration and validation errors (0.579 and 0.738) followed by the protein (0.736 and 0.765). The quality of peanut seeds with lowest root mean square error of cross validation of 0.76 and maximum correlation coefficient (R2) of 96.8 was obtained. The comprehensive results signify that FT-NIR spectroscopy can be used for rapid, non-destructive quantification of quality parameters in peanuts.

Abstract
Background

Mortality risk for hemodialysis (HD) patients varies by country and ethnicity. Here, mortality rate and its related risk factors in Chinese HD patients from the Dialysis Outcomes and Practice Patterns Study (DOPPS) were investigated.
Methods

Data from China DOPPS phase 5 (2012–2015) were used. Patients’ demographics, assigned primary causes of end stage kidney disease (ESKD), comorbidities, dialysis prescription, laboratory values, date and cause for death were analyzed. Cox proportional hazards models were used to assess the association of patient characteristics and treatments with mortality.
Results

1427 HD patients were enrolled. The mean age was 59.4 ± 14.9 years. The median follow-up time was 1.9 (1.1–2.1) years. There was total 205 deaths with at least 103 from cardiovascular disease (50.2%). The overall mortality rate was 8.8 per 100 patient-years. In the multivariate Cox model, older, serum albumin (Alb < 4g/dl, blood platelets < 100*109/L, pulse pressure (PP) > 63mmHg, and congestive heart failure history were independent risk factors for all-cause mortality.
Conclusions

Attention should be paid to patients who were older, with lower Alb and blood platelets level, higher PP and congestive heart failure history. Our results highlighted that there might be some modifiable risk factors for patients’ survival, such as Hgb, Alb, blood platelets, and blood pressure management.

Published: September 2021

Abstract
Background

Despite the importance of having trust in the health system, there is a paucity of research in this field in Sweden. The aim of this study was to estimate the level of trust in the health system and to assess the factors associated with it in northern Sweden.
Methods

A cross-sectional survey was conducted in 2014 in the four northern regions of Sweden. A total of 24 795 participants aged 18 to 84 years were involved in the study. A log-binomial regression was used to measure the association between sociodemographic factors and trust in the health system.
Results

Two thirds of the participants (68.5%) reported high trust in the health system. Women had lower prevalence of trust compared to men (PR = 0.96; 95% CI = 0.94–0.98) while older participants had a higher trust compared to youth (PR = 1.11; 95% CI = 1.06–1.16). Participants with lower level of education, those who experienced economic stress, those who were born outside Sweden and those living in small municipalities also had lower prevalence of trust in the health system. Conversely, lower income was associated with higher trust (PR = 1.08; 95% CI = 1.04–1.12). Finally, a strong relationship between social capital and trust in the health system was also found.
Conclusions

Trust in the health system was moderately high in northern Sweden and strongly associated with sociodemographic and social capital factors. Trust is a complex phenomenon and a deeper exploration of the relation between trust in the health system and sociodemographic factors is needed.
