A combined isopiestic and sub-boiling distillation method for the purification of hydrofluoric acid used for ICP-MS elemental analysis

Purification of hydrofluoric acid (HF) has been achieved by the combination of isopiestic and sub-boiling distillation. For better yield and purity, the collection vessel's position is optimized. The distillation assembly is made from polyethylene which is available in any chemical laboratory. Impure acid (100 mL) is placed in a 1-L HDPE container and the collection vessel (PTFE beaker) containing 25 mL pure water is kept inside the container on a perforated stand. The whole distillation set-up is heated in a water bath at 80°C. After eight hours, 35 mL of pure HF of ∼40% strength is obtained from 100 mL of impure 48% HF. The production of high purity HF can be increased by increasing the volume of the feed HF. The impurities in pure acid are preconcentrated in an in situ evaporating system and determined by ICP-MS after suitable dilution. The levels of impurity are in the sub-ng/g to ng/g range and the purity of the acid is close to a commercially available pure (Suprapur®) grade HF with respect to Cd, Co, Cr, Cu, Ga, In, Mg, Mn, Ni, Pb, Sr, and Zn.
Research on the Application of Binocular Vision-Based Pose Estimation Technology in Live-Line Working

To engage robots in live-line working and reduce the cost of electric power companies, this study proposes a binocular vision-based pose estimation method that can automatically identify the target’s pose, guide the robotic arms to grasp the tools and fulfill live-line working tasks. First, this method matches and calculates the deep information of images via the binocular camera, and converts the images into the cloud of points; then, the advanced image segmentation technology is used to recognize the tools, and 3D modelling is conducted for the objects to accurately match the target image and the real target; the iterative closest point (ICP) method is used to solve the spatial pose of the target corresponding to the robot and thus guide the robots in tasks. Meanwhile, experiments are conducted to simulate the actual work process, and the result shows that the proposed method can accurately estimate the pose of targets and has good robustness and application value.
Divergent Adaptation Strategies of Vascular Facultative Epiphytes to Bark and Soil Habitats: Insights from Stoichiometry

Understanding the stoichiometric traits of plants is critical for studying their ecological adaptation strategies. Facultative epiphytes (which can also live on the ground) are an important component of epiphytic flora of montane forest ecosystems. However, a key gap persists in our understanding how facultative epiphytes can adapt different nutritional conditions of ground and canopy habitats? To study adaptive strategies of facultative epiphytes and the characteristics of the content and stoichiometric homeostasis of C, N, and P elements, we conducted a field experiment and a greenhouse N and P additions cultivation experiment. We found that epiphytic individuals of facultative epiphytes showed lower C:N and C:P ratios, higher variation in elemental composition, and more pronounced N limitation than terrestrial individuals. Moreover, facultative epiphytes showed strong control over the elemental composition of leaves, and their stoichiometric homeostasis of leaves and stems were stronger than roots. Furthermore, the homeostasis of facultative epiphytes decreased in the order N > P. Our results indicated that epiphytic and terrestrial individuals of facultative epiphytes have difference in nutrient limitation, and they use plastic strategies in different habitats. Epiphytic individuals survive in the intermittent habitat through luxury consumption of nutrient while terrestrial individuals were relatively conservative nutrient users. Furthermore, our results implied that facultative epiphytes maintain stable metabolic leaf activity via variable element concentrations of roots to adapt to highly heterogeneous forest habitats.
Longitudinal Platoon Control of Connected Vehicles: Analysis and Verification

This paper proposes a longitudinal platoon controller for connected vehicles (CVs) by considering the information of multiple preceding vehicles and the car-following interactions between CVs. The stability of the proposed controller is analyzed using the Routh criterion. For the verification, we develop an integrated platoon control framework for CVs in a V2V/V2I communication environment. The proposed framework consists of two main components: simulation platform and experimental platform. In particular, the simulation platform is developed based on the TransModeler software, and the experimental platform is designed using the self-developed V2X devices. Finally, a scenario of platoon forming is taken as an example and is conducted in simulation platform and experimental platform, respectively. Results demonstrate the effectiveness of the proposed controller with respect to the trajectory and velocity profiles.
Management of Membrane Exposure Utilizing Concentrated Growth Factor (CFG) in Guided Bone Regeneration: A Clinical Report

This is a clinical case of a healthy woman with a missing upper right central incisor (#8) who requested a permanent prosthetic replacement due to endodontic failure. Clinically, she was presented with thin edentulous ridges and fibrous gingival tissue and minimal or compromised alveolar bone segment on the buccal profile as detected on cone-beam computed tomography (CBCT). The conventional treatment approach is to add pink porcelain; however, rarely does the prosthetic gingiva substitute blend well with the existing oral profile. Therefore,Guided Bone Regeneration (GBR) was done instead on #8 using the allograft [RegenOss, Neobiotech] and PTFE membrane. Upon examination, membrane exposure was detected, and the size was found to be increased in follow-up visits. The membrane was replaced with a Concentrated Growth Factor [CGF] and sutured at the site of the defect. After 12 months, a vertical and horizontal bone with adequate soft tissue emergence profile was achieved clinically, radiographically, and digitally. The delayed removal of the exposed membrane provided more time for initial bone regeneration in GBR. The replacement barrier of an exposed membrane using CGF is considered an innovative procedure with the cellular content providing vascularization and regeneration. This case concludes that CGF can be a viable alternative material to enhance GBR outcome in replacing exposed membranes.
Spatio-Temporal Dynamics of Noon-Time Temperature in Selected Cities in Sudan Savanna and Tropical Rainforest Zones of Nigeria

Urban centres in Sub-Saharan Africa have been undergoing unprecedented urbanization in the past decades at annual rates of almost 4%; with attendant impacts on the cities’ thermal conditions. This study aimed at characterizing the noon-time maximum temperature of two selected cities each in the Sudan and Tropical Rainforest zones of Nigeria. The study utilized daily ERA Interim (European Reanalysis) grid-based 2 meter above ground daily noontime maximum temperature (°C) data of the European Centre for Medium-range Weather Forecasts (ECMWF) from 1990 to 2019. R Statistical package version 3.6. 1 was employed to detect the trend and seasonality in the maximum noon-time temperature of the four cities using non-parametric Mann-Kendall trend and seasonal trend tests. The statistical properties of the data were first analyzed by graphical examination of the data, using time plots, and boxplots. Also, the normality test of Shapiro-Wilk (S-W test) was applied. Pettitt test was then employed to test for single change-point detection in the temperature series. The study revealed higher mean temperature values of 27.49°C and 25.56°C respectively for Birnin Kebbi and Kano both in the Sudan, and lower temperature values of 24.08°C and 23.17°C respectively for Ibadan and Owerri located in the Tropical rainforest. The Tau statistics for Kano, Ibadan and Owerri are 0.07084, 0.09848 and 0.09113 and the corresponding p-values are 0.0447, 0.0053 and 0.0098 which are less than 0.05 alpha value; indicating significant trends for the three cities. The results also show significant seasonal increase at 0.05 significant levels in the maximum noon-time temperature series for all the locations. The study recommends urban landscape planning and design for optimization of outdoor thermal comfort and creation of heathier urban environments for the city dwellers.

Shape Focusing During the Anisotropic Growth of CuS Triangular Nanoprisms

Nanocrystals composed of CuS that exhibit semimetallic behavior are capable of supporting localized surface plasmon resonances in the near-infrared wavelengths. A major challenge in utilizing these nanocrystals for plasmonic applications is the ability to accurately control their nanoscale morphology and chemical composition, both of which are known to affect plasmon wavelength and amplitude. Here, we investigate the important role of halide ions in controlling the solvothermal synthesis of colloidal CuS nanocrystals. When oleylamine is used as a stabilizing surfactant, we find that the addition of halide ions to the reaction mixture instigates nanocrystal shape focusing in a process similar to Ostwald ripening, from nanodisks to faceted triangular prisms. We demonstrate that this shape focusing is likely to occur from the competition between CuS surface binding interactions with oleylamine ligands and halide ions and is the strongest for I– ions. We also demonstrate that this shape focusing, in combinati.
Sleep quality assessment among college students using Pittsburgh Sleep Quality Index in a municipal corporation area of Uttarakhand, India.

Introduction Poor sleep quality have been reported among adults in most countries and are increasingly been reported in their predecessors, the college students. The present study aimed to assess sleep patterns and determine its association with various correlates amongst college students for effective and timely interventions in the habit-forming years of the life. Methodology This was a cross sectional study done among college students enrolled in different courses, in Rishikesh municipal corporation area, in Dehradun district of Uttarakhand, India. Sleep Quality was assessed using a validated Pittsburgh Sleep Quality Index (PSQI), which has seven components while Perceived Stress Scale-10 assessed Stress. Results Poor sleep quality was reported among 66% of respondents. Mean sleep latency among respondents was 27.2 minutes (SD 20.75 min), with a median and mode of 20 minutes and 60 minutes respectively.On logistic regression analysis, yoga/ meditation, which have been recognized as effective relaxation techniques since ages, were found to have a positive association with better sleep quality (OR 0.47, 95% CI (0.26 - 0.84). Stress (OR 4.10, 95% CI 1.71- 9.83) and mobile use before bedtime (OR 1.956, 95% CI: 1.02- 3.75) were also significant predictors of poor sleep quality. Conclusions and recommendations The prevalence of poor sleep quality was quite high. Relaxation techniques such as yoga/ meditation and stress relieving workshops may pay rich dividends. Use of electronic devices before bedtime need to be restricted for better sleep quality.
Optimization of pocket cycle machining process in computer numerically controlled milling machining

The objectives of this study were: (1) to analyze the ratio of the time required for the roughing process of making a pocket (pocket) from several different strategies for the roughing process, and (2) to analyze the wear of cutting tools for the roughing process of making a pocket from several kinds of roughing cutting method. The research method used was experiment. The materials used are the work piece of mild steel (ST37) and the cutting tool HSS End mill with a diameter of 10 mm with 2 flutes. The machine used was a CNC milling machine and the software used was Master Cam X7. Retrieval of data using a built-in time-measuring instrument, vernier caliper, micrometer, and a digital micrometer with a magnification of 600x to 1000X. Data were analyzed by comparing the time required for each cutting method (8 kinds of methods) on CADCAM and the time on the actual CNC milling machine. The results showed: the fastest time required for roughing the pocket size 80 mm x 80 mm in 6 mm was the zigzag cutting method with straight-in feed (41 minutes 46.68 seconds in the CAM simulation and 42 minutes in machining using a CNC Milling machine), and the longest time is the true spiral cutting method with a ramping in-feed (62 minutes 20.59 seconds in the Master Cam X7 simulation and 62 minutes 21 seconds in the machining process using a CNC Milling machine). The wear of tools for the zigzag cutting method is greater than the true spiral cutting method. The optimization of the pocket making process in a CNC milling machine is calculated based on time and wear, if machining time is the goal, the zigzag cutting method is chosen and if the durability of the cutting tool is the goal, the true spiral cutting method is chosen.

Silver nanoparticles from Ziziphus spina-christi (L.) Desf. fruits extract and their antimicrobial activity

An easy and ecofriendly method to synthesize silver nanoparticles from different stages of ripening fruit extracts of Ziziphus spina-christi is demonstrated. UV-Vis spectroscopy showed a surface resonance peak at 423, 428 and 438 nm corresponding to the formation of AgNPs from ripened, unripened and young fruits, respectively. On the basis of XRD analysis the particle size of three stages of fruit ripening was found to range between 16.5 and 50.76 nm and all had silver metal which was confirmed by EDX. The inhibitory efficacy of AgNPs increased with the ripening progress such as ripened fruit > unripened fruit > young fruit against all tested human pathogenic microbes.
Morphological and genetic characterisation of the introduced copepod Lernaea cyprinacea Linnaeus (Cyclopoida: Lernaeidae) occurring in the Murrumbidgee catchment, Australia

Lernaea is a genus of freshwater parasitic copepod, consisting of around 80 species. The anchor worm (L. cyprinacea) is the most well-known species because of its wide distribution beyond its native range and significant effect on freshwater host species. In Australia, nearly all reported Lernaea infections are referred to as L. cyprinacea without molecular evidence. Identification solely based on morphological features is not reliable due to the highly variable morphology of Lernaea species, especially of the most important characteristic, the anchor. In Australia, the species has now been found on many native fish, including in the Murrumbidgee catchment area, which is home to several endangered species. To provide clear identification of Lernaea species, we sampled Lernaea from six fish species from various localities in the Murrumbidgee catchment, south-eastern Australia. The Lernaea specimens were described using combined traditional morphological observation and three gene regions. Although significant morphological variations were found, limited genetic differences in all three gene regions suggested they all belong to one species. Phylogenetic analyses of all tested species and those reported from other parts of the world suggested our specimens are L. cyprinacea. This study provides strong evidence for the occurrence of an introduced invasive species in Australia.
FULLY OPTIMIZED MULTILAYER RADAR ABSORBER DESIGN USING MULTI-OBJECTIVE ABC ALGORITHM

Main purpose of the design of multi-layer radar absorber (MRA) by means of metaheuristic optimization algorithms is to minimize both the total thickness (TT) of MRA and the maximum reflection coefficients for transverse electric (RTE) & transverse magnetic (RTM) polarizations at any oblique angle of incidence. For this purpose, sequence and thicknesses of layers of the MRA have been optimized by either single-objective approach based on combining all objectives or double-objective approach in which TT is evaluated separately from the reflection coefficients. In this study, triple-objective artificial bee colony (TO-ABC) algorithm integrated with Pareto front technique is proposed for fully optimized MRA design. Thus, both RTE, RTM and TT are simultaneously minimized by optimizing thickness, sequence and number of the layers. To demonstrate the superiority of TO-ABC, 3 types of MRAs operating at the frequency ranges of 2–18 GHz for each angle of incidence from 0⁰ to 60⁰ are optimized and compared with the literature. Furthermore, 4 different real MRAs are also optimized using real materials given in the literature. Thanks to the developed graphical user interface and TO-ABC algorithm, despite the limited number of materials, all possible solutions providing the specified parameters are easily achieved and successful MRA structures are designed.
Are Chapter 31 Military Veterans Returning to College More Likely to Choose Intrinsically-oriented Versus Extrinsically-oriented Majors?

Helping military veterans successfully transition to civilian life is an important issue. Education can help with this transition. No prior studies were found on the general type of undergraduate major United States (US) Chapter 31 veterans enroll in. Chapter 31 provides tuition benefits to help entitled transitioning military veterans, with service-connected disabilities, go to college to obtain a degree. Self-determination theory (SDT) suggests two general categories of majors, intrinsic (I) versus extrinsic (E). Intrinsic motivation emphasizes doing a task for its inherent satisfaction, while extrinsic motivation targets doing the same task to achieve external rewards, such as compensation. Archival data was analyzed using small samples of undergraduate Chapter 31 military veterans in 2016, 2018 and 2020. Overall, the results supported the research question, i.e., Chapter 31 veterans will be more likely to choose intrinsically motivating versus extrinsically motivating college majors. Results, including limitations and suggestions for future research are discussed.
The Role of Country Governance on the Relationship between Firm Governance and Firm Performance: Evidence from Emerging Countries

This study examines the moderating effect of country governance on the relationship between firm governance and firm performance in emerging countries. We employ a panel regression model on 21 emerging countries over the period 2007 to 2016. We find that poor firm governance is negatively linked to Tobin’s Q, but positively linked to return on assets (ROA) and return on equity (ROE), while country governance has a consistent positive moderating effect on all three performance variables. Specific country governance dimensions include voice and accountability, government effectiveness, regulatory quality, the rule of law and control of corruption also have significant positive moderating effects. We further find that only a strong legal environment can compensate for the ineffectiveness of firm governance but not in a weak legal environment and only countries with strong country governance can positively affect firm value.
Lumped heat and mass transfer coefficient for simulation of a pressure swing adsorption process

ABSTRACT The practical implications of replacing various individual transport resistances such as gas-solid mass and heat transfer, and gas phase axial dispersions of mass and heat in a numerical model of a pressure swing adsorption (PSA) process by a single, empirical, lumped, effective mass transport coefficient were evaluated. A non-isothermal, adiabatic, four-step Skarstrom-like PSA process for production of pure helium from a binary helium-nitrogen mixture using 5A zeolite adsorbent was considered. It was found that the above-described model simplification was adequate to describe key process performances such as the bed size factor and the product recovery vis-a-vis a detailed model where the effects of all individual resistances were explicitly included.
