Characterization of an α-haloalkanoic acid–degrading Pseudomonas aeruginosa MX1 isolated from contaminated seawater

ABSTRACT Halogenated compounds such as α-halocarboxylix acids (αHAs) are widely liberated into the ecosystem through the prevailing xenobiotic activities that involve the use of herbicides for weed management in the agricultural sector and mass production of various commercial halogenated chemical intermediates. Since such compounds exert stress on the environment owing to their recalcitrance and are not easily degraded, the study aimed to isolate, identify, and characterize dehalogenase-producing bacteria with the purpose of bioremediation. The MX1 bacterium was successfully isolated from seawater samples off the coast of Desaru, Malaysia, using an enrichment technique supplemented with 2,2-dichloropropionic acid (2,2-DCP). Interestingly, the MX1 strain grew best in a 20 mM 2,2-DCP minimal medium as the sole carbon source and illustrated a 44 ± 0.2 h cell-doubling time as well as a 38 μmol Cl−/ml maximum rate of chloride ion release. However, 2,2-DCP–containing medium with concentrations that exceeded 30 mM inhibited the growth of the MX1, possibly attributable to the increased toxicity of the compound on the bacteria. Biochemical examinations and 16S rDNA sequence analysis revealed that the MX1 strain shares high identity to Pseudomonas aeruginosa, and the gene sequence was deposited into GenBank as Pseudomonas aeruginosa MX1 under accession number KP336490. The presence of the putative dehalogenase gene in the MX1 strain was established by polymerase chain reaction (PCR) analysis, which proved the presence of conserved amino acid residues belonging to the Group I dehalogenase. This is the first report detailing a P. aeruginosa strain capable of degrading the recalcitrant 2,2-DCP and its functional amino acid residues.
The impacts of high-commitment HRM practices on exploitative and exploratory innovation: the mediating role of knowledge sharing

Purpose The purpose of this paper is to investigate the mediating roles of knowledge sharing behaviors (knowledge collecting and donating) in linking the relationship between high-commitment human resource management (HRM)practices and specific aspects of innovation capability, namely, exploitative and exploratory innovation. Design/methodology/approach The paper is based on quantitative approach and structural equation modeling to examine the correlation among the latent constructs based on the survey data collected from 281 participants in 95 Chinese firms. Findings The findings of this study support the mediating role of knowledge sharing (KS) behaviors in the relationship between HRM practices and aspects of innovation capability. It highlights the important role of knowledge donating and indicates that the effect of knowledge donating is more significant than that of knowledge collecting on exploitative and exploratory innovation. Research limitations/implications Future research should investigate the impact of high-commitment HRM practices on innovation capability under the moderating effects of organizational variables to bring better understanding on the relationship among them. Originality/value The paper significantly contributes to increasing knowledge and insights on the correlation between high-commitment HRM practices and specific forms of innovation. The understanding on mediating role of KS contribute to advancing the body of knowledge of HRM and innovation theory.
Who and How Do I Include? A Case Study on Teachers’ Inclusive Education Practices

The purpose of this study was to determine the perceptions and practices of teachers about inclusive education and to propose solutions to the problems experienced by the teachers in the light of the study findings. The study was carried out by qualitative research approach and case study design was used. The participants of the study consisted of 20 primary school teachers who worked in public schools in the 2019-2020 academic year and participated voluntarily in this study. Data were analyzed through descriptive analysis technique. As a result of this study it was found that the teachers experienced a lack of conceptual clarity regarding the definition of inclusive education and a great majority of them focused on the main philosophy of inclusiveness, yet few of them attempted to relate inclusiveness to instructional practices. Moreover, the findings revealed that the teachers did not perform activities directed to the application of inclusive education in their classes and that they had different expectations from the Turkish Ministry of National Education, school administrations, non-governmental organizations (NGOs), and parents.

When saving is not enough – wealth decumulation in retirement

Abstract We field a large online survey to study preferences and hypothetical product choices for phased withdrawal accounts and compare their demand to the demand of annuities. We find that most individuals prefer phased withdrawal accounts with dynamic withdrawal rates and equity-based asset allocation. Additionally, when offered the opportunity to exchange the phased withdrawal account with an annuity, most individuals decline to annuitize. Our results suggest that policymakers should consider offering combined solutions of phased withdrawals and annuities. Retirees who are averse to full annuitization could preserve some of their accumulated wealth while also acquiring protection against longevity risk.

Effect of Different Anthropometric Body Indexes on Radiation Exposure in Patients Undergoing Cardiac Catheterisation and Percutaneous Coronary Intervention

Background: Patient factors, such as sex and body mass index (BMI), are known to influence patient radiation exposure. Body surface area (BSA) and its association with patient radiation exposure has not been well studied. Methods and Results: We analysed height, weight, BMI and BSA in consecutive patients undergoing cardiac catheterisation and percutaneous coronary intervention (PCI) at a high-volume Australian centre between September 2016 and April 2020 to assess their association with dose–area product (DAP, Gycm2). The mean age of the cohort was 64.5 ± 12.3 years with males comprising 68.8% (n = 8100, 5124 diagnostic cardiac catheterisation cases and 2976 PCI cases). Median male BMI was 28.4 kg/m2 [IQR 25.2–32.1] versus 28.8 kg/m2 [24.7–33.7] for females, p = 0.01. Males had higher BSA (2.0 ± 0.2 m2) than females (1.78 ± 0.2 m2), p = 0.001. Each 0.4 m2 increase in BSA conferred a 1.32x fold change in DAP (95% CI 1.29–1.36, p ≤ 0.001). Each 5 kg/m2 increase in BMI was linked to a 1.13x DAP fold change (1.12–1.14, p ≤ 0.001). Male sex conferred a 1.23x DAP fold change (1.20–1.26, p ≤ 0.001). Multivariable modelling with BMI or BSA explained 14% of DAP variance (R2 0.67 vs. 0.53 for both, p ≤ 0.001). Conclusions: BSA is an important anthropometric measure between the sexes and a key predictor of radiation dose and radiation exposure beyond sex, BMI, and weight.

Creatinine Trends and Patterns in Neonates Undergoing Whole Body Hypothermia: A Systematic Review

Many neonates undergoing whole body hypothermia (WBH) following moderate to severe perinatal asphyxia may also suffer from renal impairment. While recent data suggest WBH-related reno-protection, differences in serum creatinine (Scr) patterns to reference patterns were not yet reported. We therefore aimed to document Scr trends and patterns in asphyxiated neonates undergoing WBH and compared these to centiles from a reference Scr data set of non-asphyxiated (near)term neonates. Using a systematic review strategy, reports on Scr trends (mean ± SD, median or interquartile range) were collected (day 1–7) in WBH cohorts and compared to centiles of an earlier reported reference cohort of non-asphyxia cases. Based on 13 papers on asphyxia + WBH cases, a pattern of postnatal Scr trends in asphyxia + WBH cases was constructed. Compared to the reference 50th centile Scr values, mean or median Scr values at birth and up to 48 h were higher in asphyxia + WBH cases with a subsequent uncertain declining trend towards, at best, high or high–normal creatinine values afterwards. Such patterns are valuable for anticipating average changes in renal drug clearance but do not yet cover the relevant inter-patient variability observed in WBH cases, as this needs pooling of individual Screa profiles, preferably beyond the first week of life.
Impact on fetal outcome following burns in pregnancy

After approval of Institutional Ethics Committee, we conducted a retrospective observational study that included all pregnant patients with burns injury admitted and managed at a tertiary hospital under department of General Surgery from June 2017 to May 2019. A total of 20 cases were included in this study. All cases were managed by a combined team of surgeons and obstetricians. Baseline investigations and confirmation tests for pregnancy including urine dipstick tests and ultrasonography were done in all cases. The rule of nine was used to determine the percentage of burns according to total body surface area involved by parkland’s formula. Data analysis was carried out with primary focus towards maternal outcome.
Improved flood forecasting using geomorphic unit hydrograph based on spatially distributed velocity field

This paper presents an energy model for determining the overland flow velocity in order to improve the low accuracy problem in flow concentration simulation. It furnishes a novel idea for studying flow concentration in ungauged basins. The model can be widely applied in analysis of spatial velocity field, extraction of instantaneous geomorphic unit hydrograph and development of distributed hydrological model. A distributed flood-forecasting model is constructed for Lianyuan Basin in Hunan Province of China. In the proposed method, gravitational potential energy is transformed into kinetic energy via an analysis of energy distribution of water particles in the basin. Based on the kinetic energy equation, the overland flow velocity simulating the geomorphic unit hydrograph is computed. Rainfall-runoff simulation is then performed by integrating with runoff yield and concentration model. Results indicate that the model based on energy conversion leads to more accurate results. The model has the following advantages: firstly, the spatial distribution of the velocity field is appropriate; secondly, the model has only one parameter, which is easily determined; and finally, flow velocity results can be used for the computation of river network flow concentration.
Correlation Study: CEM Scores and Customer Perception Value in Chick-fil-A Teterboro from 2018-2019

The monitoring of customer service experiences for fast food restaurants has been on the rise for past three decades because of technological advances. Having access to the current features helps businesses determine what factors to consider for improving their company. There has been research done on research chains such as Chipotle, Subway, KFC, Dairy Queen, and Taco Bell. Each restaurant focuses on similar factors, but there has been little to no research done on the fast food restaurant, Chick-fil-A regarding CEM scores and customer perception. Chick-fil-A is an extremely well known fast food place known to have outstanding customer service because of their overall politeness and fast service. This study aims at looking into one specific Chick-fil-A location in Teterboro, New Jersey, which is known to be in the top 20% of Chick-fil-As in the United States. This research study used stratified sampling in order to conduct a Spearman Correlation Analysis that answered the research question, “Is there a correlation between 4 main components of customer service and an effect on the customer service environment in Chick-fil-A Teterboro, from the years 2018-2019? ” Results concluded there were only two direct correlations between two components. The two factors that had the highest correlation with one another were Overall Customer Satisfaction levels and the Attentive/ Courteous component in connection to the overall value of the customer service environment.
Evaluating the environmental sustainability strategies of the housekeeping department: the case of an international hotel chain in Hong Kong, China

Purpose The purpose of this paper is to use the case of an international luxury hotel chain in Hong Kong to illustrate general environmentally-friendly practices in housekeeping. Six in-depth interviews were conducted with the housekeeping department staff to evaluate the effectiveness of the Hotel’s environmental sustainability practices by analysing their benefits and limitations. Results reveal that all informants acknowledged the environmental sustainability strategies adopted by the Hotel, which can benefit stakeholders. Despite multiple green practices in hotel housekeeping, several strategies may not be as significant as expected with misaligned expectations from the management and the actual practices may create excessive workload for frontline room attendants with a lack of policy enforcement and supportive policies. Therefore, hotels should keep a mutual communication between the management and frontline employees prior to conducting environmentally- and employee-friendly practices. Given the labour-intensive nature of the hotel industry, the housekeeping department should ensure employment equality policy is in place with adequate environmentally friendly support for employees.
A non‐isolated high step‐up DC–DC converter using magnetic coupling and voltage multiplier circuit

This paper introduces a new DC–DC structure with a high voltage gain. The proposed structure can achieve higher voltage gain by using magnetic coupling and voltage multiplier circuit (VMC). The VMC is also used as a clamp circuit to suppress the voltage spike through the switch which leads to increase the overall system efﬁciency. Moreover, the peak voltage through the semiconductors of the proposed converter is low. The existence of soft-switching such as zero-current switching (ZCS) in OFF-state and zero-voltage switching (ZVS) in ON-state of diodes is another merit of the proposed converter. The recommended structure uses one power MOSFET with low on-state resistance ( R DS-ON ) that leads to decrease the conduction loss. For demonstrating the proﬁciency of the proposed structure, technical analysis, mathematical survey, and comparison results with other similar previous structures are carried out. Finally, laboratory results with 200 W output power and 50 kHz switching frequency are provided, which prove the usefulness of the suggested converter. The proposed converter’s efﬁciency in 200 W output power is 96.98 %. Also, the voltage gain, maximum voltage stress across the power switch and didoes for n (turn-ratio) = 2 and D (duty-cycle) = 0.6 are equal to 10, 0.25, and 0.75, respectively.
Impact of Soil Temperature and Moisture on Mehlich-3 and Morgan Soil Test Phosphorus

Guidance for timing of sampling is seldom included in soil sampling protocols for agronomic phosphorus (P) fertilizer recommendations or P runoff risk assessment. Our objectives were to determine the influence of soil temperature and moisture content on (i) Mehlich-3 and Morgan soil test P (STP) levels and (ii) the accuracy of Mehlich-3 to Morgan STP conversion models used for nutrient management planning in New York. An incubation study with three silt loam, excessive P soils, three temperatures (5°C, 10°C, and 20°C), and three moisture contents (50%, 70%, and 90% of field capacity) showed that an increase in soil temperature from 10°C to 20°C decreased Morgan STP and showed inconsistent and small changes for Mehlich-3 STP. Both tests showed higher STP levels with soil moisture increase. The increase from 10°C to 20°C resulted in a decrease in the ratio of measured to predicted Morgan STP, reflecting a reduction in measured Morgan STP and an increase in predicted Morgan STP, mostly driven by an increase in Mehlich-3 calcium (Ca). The increase in moisture impacted the ratio of measured to predicted Morgan STP for one soil only (a pasture with native Ca content). Repeated sampling of 20 corn (Zea mays L.) fields in May, June, July, October, November, and the following April showed a large seasonal variability in STP results, with the most accurate predictions of Morgan STP from Mehlich-3 data upon sampling in October after corn harvest. We conclude that for the most accurate prediction of STP status, samples should be taken directly after corn harvest, especially when conversion equations that include pH and Mehlich-3 P, Ca, and aluminum are used.
Effects of Treatment Combining 9300 nm Carbon Dioxide Lasers and Fluoride on Prevention of Enamel Caries: A Systematic Review and Meta-Analysis

The objective of this study is to conduct a systematic review of the literatures on the effect of treatment combining 9300 nm carbon dioxide (CO2) lasers and fluoride on prevention of enamel caries. A literature search was performed using PubMed, Scopus, and Web of Science. The keywords were ((9300 nm) OR (9.3 µm) OR (carbon dioxide laser) OR (carbon dioxide lasers) OR (CO2 laser) OR (CO2 lasers)) AND ((fluoride) OR (fluorides)) AND ((dental caries) OR (caries) OR (remineralization) OR (remineralization) OR (demineralization) OR (demineralization)). Meta-analysis was performed to compare the change in mineral content by laser irradiation and fluoride treatment (F + L) with that of fluoride treatment (F) and laser treatment (L). The search identified 946 potential publications and five laboratory studies using a chemical model for cariogenic challenge and determining mineral loss of the enamel were included in this review. Meta-analysis comparing F + L with L on enamel showed a standard mean difference of −1.58 (CI: −2.13, −1.03). Meta-analysis comparing F + L with F on enamel showed a standard mean difference of −1.84 (CI: −2.30, −1.39), with low heterogeneity (I2 = 49%, p = 0.04). In conclusion, F + L was better than L and F in preventing enamel demineralization.
On the Performance of UAV-Aided Content Caching in Small-Cell Networks with Joint Transmission

Unmanned aerial vehicles (UAVs), featured by the high-mobility and high-quality propagation environment, have shown great potential in wireless communication applications. In this paper, a novel UAV-aided small-cell content caching network is proposed and analyzed, where joint transmission (JT) is considered in the dense small-cell networks and mobile UAVs are employed to shorten the serving distance. The system performance is evaluated in terms of the average cache hit probability and the ergodic transmission rate. From the analytical results, we find that (i) the proposed UAV-aided small-cell network shows superior caching performance and, even with a small density of UAVs the system’s cache hit probability, can be improved significantly; (ii) the content’s optimal caching probability to maximize the cache hit probability is proportional to the (K+1)-th root of its request probability, where K is the number of small-cell base stations that serve each user by JT; (iii) caching the most popular content in UAVs may lead to a low transmission rate due to the limited resource offered by the low-density UAVs. Simulation results are presented to validate the theoretical results and the performance gain achieved by the optimal caching strategy.
Goldmann Tonometry and Corneal Biomechanics

Glaucoma is the second cause of irreversible blindness in the world. Intraocular pressure (IOP) is a recognized major risk factor for the development and progression of glaucomatous damage. Goldmann applanation tonometry (GAT) is internationally accepted as the gold standard for the measurement of IOP. The purpose of this study was to search for correlations between Goldmann tonometry and corneal mechanical properties and thickness by means of in vitro tests. IOP was measured by the Goldmann applanation tonometer (GIOP), and by a pressure transducer inserted in the anterior chamber of the eye (TIOP), at increasing pressure levels by addition of saline solution in the anterior chamber of enucleated pig eyes (n = 49). Mechanical properties were also determined by inflation tests. The GAT underestimated the real measurements made by the pressure transducer, with most common differences in the range 15–28 mmHg. The difference between the two instruments, highlighted by the Bland–Altman test, was confirmed by ANOVA, normality tests, and Mann–Whitney’s tests, both on the data arranged for infusions and for the data organized by pressure ranges. Pearson correlation tests revealed a negative correlation between (TIOP-GIOP) and both corneal stiffness and corneal thickness. In conclusion, data obtained showed a discrepancy between GIOP and TIOP more evident for softer and thinner corneas, that is very important for glaucoma detection.
