Contact angle and surface tension of water on a hexagonal boron nitride monolayer: a methodological investigation

ABSTRACT Recently, many works have been focused on the wetting properties of water on hexagonal boron nitride (hBN) monolayers given their potential application as reverse osmosis membrane in desalination processes. Among interfacial properties contact angle and surface tension are probably the most studied. In this work, we investigated the computational procedures such as electrostatics interactions calculation, the cutoff and the force field effects on the modelling of water nanodroplet on hBN monolayer to provide the cheapest route in terms of computational time. Surface tension of solid–liquid () and solid–vapour ( interfaces, the Young's contact angle and the line tension were also managed by combining the direct calculation and the Young–Dupré equation. For the first time was evaluated whereas a negative line tension of order of magnitude of 10−15 N was calculated in fair agreement with the theoretical works.
Cemented versus cementless hemiarthroplasty for intertrochanteric femur fractures in the elderly

To compare the outcomes of the treatment of unstable intertrochanteric fractures in elderly patients who underwent cemented and cementless bipolar hemiarthroplasty. 65 patients who had AO type 31-A1 and 31-A2 fractures were divided into two groups; group 1 included 30 patients who underwent cemented hemiarthroplasty, and group 2 included 35 patients who underwent cementless hemiarthroplasty. Demographic findings, intraoperative blood loss, operation duration, hospital stay duration, blood transfusion amount, intraoperative and postoperative complications, preoperative and postoperative serum hemoglobin values, and new mobilization scores (NMS), Harris Hip Score (HHS), Likert pain scales were all assessed. Mean age of 39 (40%) female and 26 (60%) male patients was 80.86 years. The mean operation duration was 69.66 (SD 7.53) minutes for group 1 and 60.00 (SD 8.04) for group 2 and statistically different (p<0.001). HHS and Likert scores following both techniques were statistically similar between both groups (p=0.195, p=0.380, respectively). Blood loss, blood transfusion amounts, radiologic and clinical complication rates, hospital stay durations were all similar between both groups. The results show that cemented and cementless hemiarthroplasty are both viable treatments for intertrochanteric femur fractures, yielding similar clinical outcomes and complication rates. In need of revision, cemented prosthesis revisions may be more complicated, and complications may be more frequently seen.
Service Quality of Higher Education in the Selected Govt. Colleges of Northern Bangladesh: An Evaluation on Servqual Dimensions

To speed the rate of higher education government (govt.) has increased and promoted the number of govt. degree level institutions as higher level honor’s and master’s institution. There is no measure to ensure quality of these higher educational institutions as prescribed in the public universities or international universities. To know service quality and performance of the service provider groups measuring service quality is very much significant. For this purpose, we have to measure students’ expectations from the service entity and their perceptions about the actual services they get. The govt. colleges that provide higher education need to understand the customers’ (students’) perceptions of service quality and identify the gaps between their expectations and these perceptions. This part of the research studies students’ expectations and perceptions of service quality in the present educational environment by using the modified service quality (SERVQUAL) model given by Parasuraman et.al for distinctive nature of service. The modified SERVQUAL instrument will measure five dimensions i.e. tangibles (academic, non-academic), reliability, responsiveness, assurance and empathy. This study has been done over 382 undergraduate and post graduate students of selected four govt. colleges from top ten ranking 2016 by National University of northern division Rajshahi and Rongpur. Next the descriptive statistical analysis with mean scores, standard deviation and crosstabs in different perspective by colleges and respondents with service dimensions. Service quality has been measured by subtracting students’ expectations mean scores from their perceptions mean scores of different service items related to educational services based on SERVQUAL dimensions. A structured questionnaire has been supplied with same type questions to know students’ expectations and perceptions with a 5 point Likert type scale. The study found that all the SERVQUAL components has made negative scores of service quality of higher education in govt. colleges.
Light hydrocarbon geochemistry of crude oils from Eastern Niger Delta

Abstract Geochemical evaluation of oil samples from the eastern part of the Niger Delta divided into western, eastern, and central sections of the study area was carried out for the characterization of their light hydrocarbons content in order to correlate oils from different parts. The hydrocarbons in the oil samples were determined using gas chromatographic (GC) technique. The results obtained showed that CPI, Pr/Ph, Pr/nC17, and Ph/nC18 ratios ranged from 0.99–1.55, 2.19–4.79, 0.92–2.35, and 0.27–0.47, respectively. The Pr/nC17 versus Ph/nC18 plot showed that the oils were derived from terrestrial organic materials that were deposited under oxic to suboxic conditions. They are moderately matured with minimal effect of biodegradation on most of the oil samples although two of the oils showed relatively higher degradation. Both bivariate and multivariate plots of the light hydrocarbon ratios differentiated the western and central oils from the eastern oils. The classification of the oils into families was not based on origin but rather on post generative alterations that include reservoir conditions and possibly migration effects. The light hydrocarbon parameters identified can be used in the correlation tools.
Reduction of Inpatient Fall Rate in an Adult Acute Care Setting

Practice Problem: Falls are among the most reported hospital-acquired conditions and can lead to severe injuries, increased length of hospital stays, pain, distress, and emotional trauma in the elderly. The Centers for Medicare and Medicaid Services (CMS) identifies falls as preventable and no longer authorizes reimbursement to healthcare systems for treating inpatient fall-related injuries. PICOT: The PICOT question that guided this project was: In adult acute care patients admitted to the telemetry unit (P), how does implementing evidence-based multimodal fall prevention strategies (I) compared to routine fall prevention strategies (C) affect inpatient fall rate (O) over a period of 6-8 weeks (T)? Evidence: The literature review revealed that using multimodal risk prevention strategies effectively reduces fall risk and fall-related injuries and thus improves patient safety and outcomes. Intervention: A multimodal fall prevention strategy was developed, according to the Morse Fall Risk Assessment score, utilizing tools such as bed alarm on, lights on, a urinal within reach, purposeful hourly rounding, and bedside reporting during shift change. The oncoming shift nurse checked with the off-going shift nurse at the patient’s bedside to ensure that the fall risk patients’ fall precaution strategies had been initiated and maintained throughout the shift. Outcome: The EBP project did not result in an overall reduction in the fall rates; however, the fall rate with injury was low in the telemetry unit. The project resulted in an increase in the staff’s knowledge and awareness of multimodal fall prevention strategies. Conclusion: The reduction in the incidence of falls after the implementation of the EBP project in the telemetry unit was not statistically significant. However, the result indicated a clinically REDUCTION OF INPATIENT FALL RATE 3 meaningful improvement in fall-related injury outcomes and increased staff knowledge and awareness of the fall prevention strategies.

Post-reclamation Age Effects on Soil Physical Properties and Microbial Activity Under Forest and Pasture Ecosystems

ABSTRACT During surface mining and subsequent reclamation efforts, physical, chemical, and biological properties of soils are disturbed. A study was conducted to evaluate the effects of age chronosequence on soil physical property and microbial activity in chronosequence reclaimed sites covering successional ages in the ranges 1, 4, 8, 11, and 13 years under forest and pasture ecosystems. The adjacent normal and unmined pasture and forest were used as a control for comparison purposes. The study site was located at the Red Hill Mine in east central Mississippi (approximately 33.3 N latitude and 89 W longitude), which is used by the North America Mining Company, LLC. Soil samples were collected from the reclaimed and unmined sites at 0–15- and 15–30-cm depth and analyzed for selected soil quality indicators. Results indicated that water stable aggregate and infiltration were increased, but soil bulk density and compaction decreased with increasing reclamation age. Soil penetration resistance was greater in the pasture than forest ecosystem. All reclaimed soils had less microbial enzyme activity than an unmined forest ecosystem; however, bacteria population level after 11 years since reclamation was similar to that of unmined forest soils. Soil organic carbon increased with increasing reclamation age strongly correlated with soil physical indicators and appears to be the main driving force during the development of soil physical and biological properties in the humid southeast.
Study of microstructure, hardness and thermal properties of Sn-Bi alloys

Lead-free solders have become a main focus of the electronic industry in recent years, because of the high toxicity of lead. Alloys based on the Sn-Bi system figure as potential replacements for Sn-Pb alloys in soldering due to favorable properties and low cost. One of the main advantages of these alloys are low melting temperatures, while additional advantages include good compatibility with substrates, low process temperature, high reliability, and potential applications in conjunction with reduced graphene oxide nanosheets as thermal interface materials. In this paper, characterization of microstructural and thermal properties as well as hardness measurements of seven alloys of different Sn-Bi compositions are performed. Structural properties of the samples were analyzed using optical microscopy and scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM-EDS). Thermal conductivity of the samples was investigated using the xenon-flash method, and phase transition temperatures were measured using the differential scanning calorimetry (DSC) analysis.
MICROWAVE SYNTHESIS OF SILVER NANOPARTICLES BY POLYOL METHOD AND TESTING THEIR SYNERGISTIC ANTIBACTERIAL ACTIVITY IN THE PRESENCE OF VANCOMYCIN

Objective: The aim of this study is to prepare silver nanoparticles (AgNPs) and nanorods using polyol under microwave heating method. Methods: The synthesized nanoparticles were characterized using UV-visible, infrared spectral studies (Fourier-transform infrared [FTIR]), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Finally, the antibacterial activity of polyethylene glycol (PEG) protected AgNPs, against a series of Gram-positive and Gram-negative bacteria, was studied. Results: From UV-visible spectroscopy studies, the growth rate of AgNPs was confirmed by measuring the change in absorbance of plasmon peak shape at different time intervals. FTIR spectroscopy studies showed the changes in the metal and the capping agents. SEM and TEM images revealed that very stable colloidal solutions of AgNPs with almost spherical and rod shape along with high monodispersity can be obtained with PEG protected AgNPs. Finally, the antibacterial activity of PEG protected AgNPs was investigated, which showed a synergistic role for the AgNPs along with vancomycin. Conclusion: Uniform and stable polymer protected AgNPs were synthesized using ethylene glycol, triethylene glycol, and PEG as reducing agent in the presence of polyvinylpyrrolidone.
A Bridging Carbonyl of Unlikely Geometry: On the True Nature of the Technetium Complex [Tc2(μ-CO)2(CO)6(NC5H5)2]

The title compound was reported a decade ago by Zuhayra et al as the main product of the reaction of [Tc2(CO)10] with pyridine at room temperature. Chemical information, coupled to density functional theory calculations, have now been used to show that the "bridging carbonyls" then proposed from the crystallographic data most likely correspond to bridging hydroperoxide groups.

Multicomponent Vapor–Liquid Equilibrium Measurement and Modeling of Ethylene Glycol, Water, and Natural Gas Mixtures at 6 and 12.5 MPa

High pressure subsea natural gas dehydration (NGD) units using ethylene glycol (MEG) absorption have been proposed. To expand the experimental database and assist design qualification, new vapor–liquid equilibrium (VLE) experimental data have been measured for a 20-component glycol–water–natural gas mixture at T = (288–323) K, p = (6.0, 12.5) MPa, and wMEG,feed = (90, >99.8) %. MEG, H2O, CO2, N2, and alkane (methane to n- and i-pentane) phase distributions have been quantified. Experimental uncertainty ranges from ±2–42%, with the greatest uncertainty for the quantification of trace components. Experimental results are modeled using the Cubic-Plus-Association (CPA) equation of state. Overpredictions (∼9%) are observed for the water content of the vapor phase. CO2 is shown to have a large effect on yMEG, leading to modeling deviations in the order of 65%. A relatively accurate prediction of the natural gas partition coefficients was observed for major components C1–C3 and CO2, with modeling errors ranging .

A Relative Analysis of Genetic Algorithm and Binary Particle Swarm Optimization for Finding the Optimal Cost of Wind Power Generation in Tirumala Area of India

Although India presently holds the global fourth-biggest instated Wind Power Generation (WPG) capability, it necessitates advancing more rapidly to satisfy the rising energy requirement of its evolving economy while restraining the consequential greenhouse gas emission. To accomplish the impressive target of setting up 140 GW WPG competence by 2030 as proposed by the Government of India, a greater number of financially viable wind farms are required to function all over the country without further ado. This paper focuses on finding the optimal cost for WPG in the Tirumala area of Andhra Pradesh. Genetic Algorithm (GA) and Binary Particle Swarm Optimization (BPSO) have been employed concurrently with four randomly chosen terrain conditions. The research outcomes demonstrate the superior capability of BPSO to attain the most optimal cost of energy.
Modeliranje i simuliranje Hodgkin-Huxley modela neurona korištenjem NEURON softvera

During the preperation of this thesis, the process of modeling and simulating a computer model of a neuron, and setting the desired parameters, using NEURON software is discussed in detail. Moreover, the neuron and the propagation of the action potential from a biological and computational point of view are also further explained. Using Hodgkin-Huxley's mathematical model of a neuron, this thesis describes how action potential propagate and analysis of the obtained results in NEURON software can be made and simulated. This thesis describes the function of a neuron, all the parts of which it consists and the way in which the said neuron can be computationally simulated using the Hodgkin-Huxley model of a neuron. Despite being published in the 1950s, the Hodgkin-Huxley model of a neuron is still the most optimal model for investigating neural function when changing certain parameters. In order to describe the user experience while working in NEURON software in detail, the main tools used in modeling as described. Good and bad experiences when using the NEURON software are listed and possible improvements are suggested in order to create a better program. Since NEURON software is a kind of alternative to using Matlab to model and simulate the operation of neurons, a comparison has been made between this type of software that uses an open-source license and a softvere with a paid license such as Matlab. Although there are certain shortcomings, the results of the simulations themselves speak in favor of the ease of use of NEURON software and its usefulness in modelling the function of neurons.
The Application of X-STR: Two Case Reports

The usefulness of the X-chromosomal STRs (short tandem repeats) for forensic purposes seems to be restricted, but may be valuable in some paternity cases. Due to the particular mode of inheritance, X-chromosomal X-STR has the advantage in female traces identification against male contamination and in complex kinship cases, such as deficiency cases (mother-son or father-daughter), grandparent-grandchild comparisons, half-sisters testing, etc. In this study, 4 blood samples from two paternity cases without father were examined with TYPER19 Amplification kit first, from the result, it is hard to judge the relationship between the mother-sons, then TYPERX19 kit was conducted to obtain the full profiles of the two pairs of the mother-son, from the genetypes of the samples, it can be inferred that neither of the two pairs of mother-son were in line with the kinship, which provides important evidence for the two paternity cases. All together, the X-chromosome marks included in the TYPERX19 kit can offer the possibility to solve complex kinship cases where autosomal STR markers cannot provide the information needed.
The Effect of Multispectral Light Emitting Diodes (LEDs) on the Activation of Morphogenic Processes in Cell Culture of Rice Oryza Sativa l

The influence of light irradiation with different intensity parameters and different spectral composition on morphogenic structures, namely green zones of cultivar Dolinny cell cultures was investigated. Light irradiation was generated by 10 types of LEDs with different spectra: cold white (Cold W), white (W), warm white (Warm W), Full spectrum, Red, Deep Red, Yellow, Green, Blue and Royal Blue. It was shown that LEDs with Cold W, W and Royal Blue more actively influenced on green zones generation, while Red, Red Deep, Yellow и Green displayed no results. Standard fluorescent lighting illumination (WFL) was used as a control. The number of induced green zones was lower under control luminescent light (WFL) in comparison with the green zones, which were induced by the illumination of the most active spectra of LEDs, but lifetime of these control structures was longer. After 19 weeks of cultivation, degradation of the green zones of the calli was not observed under control and LEDs Cold W, Warm W, and Blue in the position with maximal intensity of light. The Royal Blue illumination displayed the same results not only in the position with maximum intensity but also at the other intensities approaching the control values (49,3 230 μmol/s*m2).
