Effect of brassinoesteroid hormone on oxidants activity of two contrasting cowpea cultivars subjected to saline stress

The aims of this study were to study the biochemical metabolism alterations generated by saline stress in two cowpea cultivars: BRS Guariba (moderately tolerant) and BR3 Tracuateua (sensitive), and to investigate the action of brassinosteroid in attenuation of oxidative stress. The results for water content and damage index in cell membranes were similar. Plants with 24-Epibrassinolide hormone maintained their water content satisfactory and without any membrane extravasation, whereas, for plants with salinity these variables decreased considerably. The results showed that salinity increased sodium (Na + ) contents and reduced potassium (K + ) content, which caused water increases allowing a higher dilution of sodium ions (Na + ), avoiding cellular toxicity. The antioxidant defense system of these plants (catalase, superoxide dismutase, ascorbate peroxidase, and guaiacol peroxidase) were activated mainly in characterization of salt stress, increasing their concentrations trying to avoid toxicity. The association of brassine and salinity caused reduction of lipid peroxidation characterized by malondialdehyde variable. These results corroborated the efficacy of the brassine hormone in cowpea plants under saline stress, characterizing as a plant plasticity.
Accuracy assessment of RTK-GNSS equipped UAV conducted as-built surveys for construction site modelling

Regular as-built surveys have become a necessary input for building information modelling. Such large-scale 3D data capturing can be conducted effectively by combining structure-from-motion and unmanned aerial vehicles (UAV). Using a RTK-GNSS equipped UAV, 22 repeated weekly campaigns were conducted at two altitudes in various conditions. The photogrammetric approach yielded 3D models, which were compared to the terrestrial laser scanning based ground truth. Better than 2.8 cm geometry RMSE was consistently achieved using integrated georeferencing. It is concluded that the RTK-GNSS based georeferencing enables reaching better than 5 cm geometry accuracy by utilising at least one ground control point.
Respiratory System of Rats Exposed to Pollutants arising out of Heating Residual Glycerol

Biofuels, such as biodiesel are renewable alternatives and environmentally safe fossil fuels. In the production of biodiesel, about 10% of the total volume is residual glycerol. This residual glycerol has impurities that prevent their direct use. Thus, it is important to search for alternatives to the direct use of such environmental liabilities. His direct combustion appears as a very promising route. Among the steps for using the residual glycerol as a fuel, no heating, with potential to generate pollutants whose effects on health are poorly investigated. This paper presents to study the effects of vapors from the residual glycerol heating in the respiratory system of rats. The animals were exposed to glycerol heating gas for 5 hours. As a result, an increase in the parameters of tissue elastance (H) and tissue resistance (G) of animals exposed to gases. Our results demonstrate that, despite the short period of exposure, there are changes in parameters related to lung tissue (G, H and CST), proving the harmful effect on the respiratory system of mice exposed to pollutants from the residual glycerol heating. This study can be used as reference works that intend to use the residual glycerol as fuel furnaces or boilers.
Federated Learning for Privacy-Preserving Data Access

Federated learning is a pioneering privacy-preserving data technology and also a new machine learning model trained on distributed data sets. Companies collect huge amounts of historic and real-time data to drive their business and collaborate with other organisations. However, data privacy is becoming increasingly important because of regulations (e.g. EU GDPR) and the need to protect their sensitive and personal data. Companies need to manage data access: firstly within their organizations (so they can control staff access), and secondly protecting raw data when collaborating with third parties. What is more, companies are increasingly looking to ‘monetize’ the data they’ve collected. However, under new legislations, utilising data by different organization is becoming increasingly difficult (Yu, 2016). Federated learning pioneered by Google is the emerging privacy- preserving data technology and also a new class of distributed machine learning models. This paper discusses federated learning as a solution for privacy-preserving data access and distributed machine learning applied to distributed data sets. It also presents a privacy-preserving federated learning infrastructure.
Search for the lepton flavor violating decay $\tau \to$ 3$\mu$ in proton-proton collisions at $\sqrt{s} =$ 13 TeV

Results are reported from a search for the lepton flavor violating decay $\tau \to$ 3$\mu$ in proton-proton collisions at $\sqrt{s}=$ 13 TeV. The data sample corresponds to an integrated luminosity of 33.2 fb$^{-1}$ recorded by the CMS experiment at the LHC in 2016. The search exploits $\tau$ leptons produced in both W boson and heavy-flavor hadron decays. No significant excess above the expected background is observed. An upper limit on the branching fraction $\mathcal{B}(\tau \to$ 3$\mu)$ of 8.0 $\times$ 10$^{-8}$ at 90% confidence level is obtained, with an expected upper limit of 6.9 $\times$ 10$^{-8}$.

Neonatal programming of piglet gut health and postnatal effects by maternal transfer of phytogenic compounds supplemented in gestating and lactating hyperprolific sows

Background The improvement of sow prolificacy by breeding has increased the number of piglets produced per sow per year. However, intrauterine crowding and/or intrauterine growth restriction typically observed in hyperprolific sows impairs foetal growth which has decreased the average individual birthweight, with a larger proportion of low birthweight (LBW) pigs born per litter with poor gut development and compromised postnatal growth performance. Phytogenic compounds (PC) are plant-derived natural bioactive substances that can be used in livestock production as feed additives to promote animal health and production efficiency. This research aims to study if a specific blend of PC (BPC) supplemented in gestating and lactating hyperprolific sow diets may promote pre- and postnatal maternal effects on performance and oxidative status of sows and their offspring, colostrum-milk features, and piglet gut health-related gene expression and morphology. Forty DanBred hybrid line Landrace x Yorkhire gilts and sows (parities 0–7) were randomly allocated by parity number and body weight into two dietary treatments including unsupplemented Control (n = 20) or Control diets supplemented with 1 g/kg feed of BPC (n = 20) throughout gestation and lactation.Results Several dietary PC from the supplemented BPC were transferred to the placental fluid and milk. The BPC supplementation during gestation enhanced the litter size, antioxidant status, and colostrum protein content of sows. Jejunal histomorphology of neonate piglets, and intestinal-function gene expression related to nutrient transport, antioxidant, innate immune response, and digestion were improved in the BPC group. For both, sows and piglets, plasma antioxidant activity of CAT and SOD enzymes were enhanced. For suckling piglets, jejunal expression of genes related to gut barrier function was improved and piglet weight gain from birth to weaning was enhanced in the BPC group.Conclusions Dietary supplementation of BPC in gestating and lactating diets for hyperprolific sows improves sow’s reproductive performance and colostrum composition, with a significant strength of the antioxidant status of sows and their offspring. The prenatal and postnatal maternal transfer (placental fluid and milk) of BPC to the offspring would influence on the neonatal programming and postnatal of piglet’s gut health, with advantageous effects on piglet’s growth performance.
Plasma-enhanced atomic layer deposition of superconducting niobium nitride

Thin films of niobium nitride are useful for their physical, chemical, and electrical properties. NbN superconducting properties have been utilized in a wide range of applications. Plasma-enhanced atomic layer deposition (PEALD) of NbN with (t-butylimido) tris(diethylamido) niobium(V) and remote H2/N2 plasmas has been investigated. Deposited film properties have been studied as a function of substrate temperature (100–300 °C), plasma power (150–300 W), and H2 flow rate (10–80 sccm). PEALD NbN films were characterized with spectroscopic ellipsometry (thickness, optical properties), four point probe (resistivity), x-ray photoelectron spectroscopy (composition), x-ray reflectivity (density and thickness), x-ray diffraction (crystallinity), and superconductivity measurements. Film composition varied with deposition conditions, but larger cubic NbN crystallites and increased film density at higher substrate temperatures and H2 flow rates lead to room temperature resistivity values as low as 173 μΩ cm and super.
INVERSION OF UNDERGROUND GOAF IN ZHENFENG COAL MINE IN GUI ZHOU PROVINCE BASED ON INSAR THREE-DIMENSION DECOMPOSITION TECHNOLOGY

Coal mined-out area, formed in mine production, usually induces a certain degree of ground subsidence and collapse. In many areas, the background information of coal seam mining is unclear, which brings trouble to the ecological restoration of the mining area and the reuse of land resources. Therefore, the calculation of the underground mining range is particularly important and can play a monitoring role in the cross-border mining of coal mines. This paper uses Japan's PALSAR-2 satellite data with a data resolution of about 3 m, and a total of 16 scenes in two observation directions of ascending and descending. Using InSAR technology, the multi-phase surface deformation monitoring is carried out in the mine goaf of Zhenfeng County, Guizhou Province. Based on the geological conditions, underground mining conditions, and field investigations in the study area, this paper calculates the relationship between mining subsidence parameters and time lags in the study area. The calculation combines the surface deformation of the known coal mines and the underground mining information. Then using the above-mentioned parameters and surface deformation information, this paper inverts an abandoned coal mine near the area and calculates the underground goaf range and mining time. The results are as follows. The study area is dominated by slow-sloping sandstone and mudstone. The coal mining strike influence angle is 83°, the uphill influence angle is 75°and the downhill influence angle is 80°. Inversion calculation gives the mining range of 380 m×150 m underground and the mining time of each area. FLAC3D numerical simulation calculation of the mined area of the abandoned coal mine is used to verify the accuracy of the range of the mined area. Compared with the calculation results of InSAR, the surface deformation trend of the mining area obtained by FLAC3D is more consistent, and the root meant square error of the trend and tendency is about 6 cm.
What is the Impact of Novel Coronavirus Disease 2019 Pandemic on Orthopedic Surgeons?: Experience from a Single Institution of South Korea

Background: This study aimed to investigate the cancellation rate and trend of orthopedic surgery at the main institution in Daegu, Korean epicenter of novel coronavirus disease 19 (COVID-19), and to analyze the psychologic status of the healthcare workers in the orthopedic division during the COVID-19 pandemic. Moreover, we sought to assess the outcomes of the preventive surgeries underwent in patients suspected to have COVID-19.Methods: Cancellation rates of elective surgeries over three months since the first confirmed COVID-19 case in South Korea on January 20, 2020 were investigated. Moreover, the number of elective surgeries conducted in the same period over the last two years was compared. Four different questionnaires were used to investigate psychologic impact among health care workers in the orthopedic department. The surveyed outcomes according to occupation and type of work were compared. Urgent preventive surgeries underwent in patients who could not wait for the results of the COVID-19 diagnosis were also investigated.Results: During the pandemic, spine and hip surgery had relatively lower cancellation rates, and elective surgeries were significantly reduced compared to the same period in the last two years. The surveyed outcomes of the psychological questionnaires were within the normal range and there were no significant differences between groups. After preventive surgeries, the virus did not spread to all medical staff involved.Conclusions: During the COVID-19 pandemic, the cancellation rate of orthopedic elective surgeries was significantly higher than in the same period of the previous year, and was different for each subdivision depending on the degree of pain or disability experienced by the patient. Health care workers in the orthopedic division did not seem to have significant psychological distress; rather, a decrease in workload appears to be a positive factor in their mental health. Preventive surgery performed in specialized facilities did not spread the virus to involved medical staff.
Relationship between Mechanical and Electrical Properties of Continuous Polymer-Free Carbon Nanotube Fibers by Wet-Spinning Method and Nanotube-Length Estimated by Far-Infrared Spectroscopy

Neat carbon nanotube (CNT) fibers produced by wet spinning methods offers a potential for high-strength and electrically conductive lightweight materials. For improving their performances, it is necessary to understand how each manufacturing process affects the raw CNTs and implicates the effects in the fiber properties. Recently, we found that the lengths of the clean CNT channels can be estimated by far-infrared (FIR) spectroscopy based on the plasmon resonance model. In this paper, the relationship between the mechanical properties and electric conductivities of the neat CNT fibers, and the lengths of the constituent CNTs are systematically studied by using different types of single-walled CNTs (SWCNTs) with various diameters and different dispersing times. Irrespective of the type of CNTs or the tube diameters, Young moduli, fracture strengths, and electric conductivities of the CNT fibers were found to be related to the CNT lengths estimated from the FIR spectra. The results prove that the evaluation.

Risk Factors of Supply Chain in Biopharmaceutical Companies in Iran

Background: Supply chain risk management can help companies detect potential hazards,mitigate potential risks, and thereby increase supply chain efficiency. The biopharmaceuticalindustry in Iran has a generic-based pharmerging market. Therefore, identifying risksassociated with the supply chain of those drugs can significantly boost the possibility of successof biopharmaceutical companies. This study is conducted to determine the supply chain riskfactors of biopharmaceuticals companies in Iran. Methods: The current research work is a qualitative-quantitative study. A systematic review andinterview with experts (n=14) were conducted to identify potential supply chain risks in thebiopharmaceutical industries. To determine the significance of identified risks, Fuzzy screeningmethod was employed to collect the opinions of experts (n=16) in the biopharmaceuticalindustries. Results: By systematic review and interviews with the biopharmaceutical industry experts, 100potential risks in the biopharmaceutical industry supply chain were identified. These risks weredivided into two general categories namely macro and micro risks. Based on experts’ judgment,77 out of 100 identified risks were eliminated and 23 significant risks were determined. Themost important risks are the Ministry of health (as the regulatory body) conflict of interest, USsanctions, lack of domestic suppliers of essential materials, pseudo-productivity, and moneytransfer related to the bank’s sanctions. Conclusion: Due to the multitude of present risks and the impossibility of controlling all ofthem, it is recommended that managers and producers focus more on controlling the identifiedsignificant risks.
Tinzaparin in Cancer and Renal Impairment: A Systematic Review Focusing on Safety

Purpose: Low-molecular-weight heparins are approved for primary and secondary venous thromboembolism prevention. The purpose of this systematic review is to provide an update regarding the safety profile of tinzaparin sodium, prescribed either as a prophylactic or as a therapeutic regimen for VTE in cancer patients and individuals suffering from renal impairment. Method: We identified and studied clinical studies from 2000 until 2020, reporting safety outcomes for cancer patients and individuals with renal impairment receiving either prophylactic or therapeutic doses of tinzaparin. Results: In patients with cancer major bleeding rates fluctuate between 0.8% and 7%; reported major bleeding rates for non-cancer patients with renal impairment on prophylactic tinzaparin regimens were 0%. Non-cancer patients on therapeutic tinzaparin regimens exhibited major bleeding in 0 to 2.3% of cases; major bleeding rates were higher for cancer patients with renal impairment receiving therapeutic doses of tinzaparin (4.3 to 10%). Patients on tinzaparin exhibit significantly lower rates of clinically relevant nonmajor bleeding events in comparison with those on vitamin K antagonists. Bioaccumulation of tinzaparin is not correlated with age, body weight or creatinine clearance. Periodic administration of either prophylactic or therapeutic doses of tinzaparin does not result in bioaccumulation, even in patients with severe renal impairment and creatinine clearance < 20 ml/min. Conclusion: Tinzaparin is safe and can be used without dose adjustment in patients with severe renal impairment and creatinine clearance > 20 ml/min. Tinzaparin represents a thoroughly studied and safe choice for special populations at increased risk for thrombosis and bleeding.
Patterns of older Australians’ engagement in health-promoting activities: a latent profile analysis

Abstract Being active in later life is key to remaining physically and mentally healthy, and health in turn influences individuals’ ability to remain active. Activity prevalence figures can disguise the existence of clusters of older people who are very active due to regular participation in multiple categories of activity versus those who are sedentary. The aim of this study was to conduct segmentation analyses based on retired seniors’ engagement in various activities (walking, active sport/exercise, gardening and volunteering) to identify groups characterised by varying patterns of participation. The sample comprised 746 Western Australians aged 60+ years (range 60–95 years, average age 71.66 years, standard deviation = 6.57), 61 per cent of whom were female. Using latent profile analysis, four distinct segments emerged. Those respondents classified as belonging to the most active group exhibited moderate to high levels of participation across all four forms of activity, and tended to be older and more educated than other respondents. Those allocated to the least active group had very low levels of participation across most of the assessed activities and the least favourable physical and mental health scores. Overall, the results indicate the existence of highly divergent segments within the older population in terms of participation across various combinations of health-promoting activities. Segment membership appears to be more closely associated with physical and psychological factors than socio-demographic characteristics.
Competência Adaptativa: um estudo sobre a influência da autodeterminação e da liderança transformacional

This study aimed to analyze the role of transformational leadership in adaptive expertise and test the mediating role of self-determination in this relationship by satisfying the psychological needs of autonomy, belonging, competence and achievement. The survey was conducted with 383 Brazilian workers. The collected data were analyzed through confirmatory factorial analysis (CFA) and multiple regressions. The results of the analyses made it possible to highlight the positive relationship between transformational leadership, adaptive expertise, and self-determination. Quadruple mediation analysis was performed to evidence the effect of self-determination on the relationship between transformational leadership and adaptive expertise. The results confirm the effect of the transformational leader on competence and the mediating effect of self-determination in this relationship. This research advances in the job demands-resources (JD-R), confirming the importance of the worker's resources and personal resources.
