The Bactericidal Activity of a Novel Aneurinibacillus aneurinilyticus Isolate Effectively Controls Foodborne Pathogens Campylobacter jejuni and Listeria monocytogenes

Human zoonotic infection with Campylobacter is a major cause of gastroenteritis in the United States and worldwide. Listeria monocytogenes causes a potentially fatal infection in humans and is often attributed to contaminated food. Genetic typing has demonstrated that Campylobacter infection is often associated with the consumption of contaminated poultry products, with Campylobacter often colonizing the poultry gastrointestinal tract, while listeriosis is commonly associated with the consumption of contaminated ready-to-eat (RTE) foods. In this study, a strain of endospore-forming bacterium (strain NH) that is bactericidal towards the human food pathogens Campylobacter jejuni and Listeria monocytogenes was identified and characterized. Transwell experiments demonstrated that the bactericidal effect on both C. jejuni and L. monocytogenes is due to secretions from the spore former. These foodborne pathogens consistently exhibited 7 log reductions in growth when exposed to the NH cell-free culture filtrate. Sequencing of the 16s rRNA gene V4 variable region and analysis of the full-length 16s rRNA gene sequence from the WGS indicated that strain NH belongs to the species Aneurinibacillus aneurinilyticus. A microplate bioassay demonstrated that a bactericidal substance that is sensitive to protease could be collected from cell-free filtrates by salting out with ammonium sulfate. Gel filtration chromatography indicated a native molecular weight for the bactericidal protein of ca. 50 kDa, consistent with a class III bacteriocin. The active protein bound strongly to a cation-exchange resin and with an isoelectric point of ten, suggesting a positively charged protein. Both cation-exchange chromatography and isoelectric focusing indicated the enrichment of an 11 kDa protein on SDS-PAGE. This protein was identified through mass spectroscopy as the flgM protein, an anti-sigma factor. Analysis of whole genome sequencing (WGS) of the strain NH genome indicated the presence of a number of non-conservative amino acid substitutions in the flgM-gene-derived amino acid sequence of strain NH and A. aneurinilyticus compared to other members of the Aneurinibacillus genus. Further investigation is needed to determine whether these substitutions are correlated with the bactericidal activity. The identified strain may be useful as a feed additive for the pre-harvest control of Campylobacter jejuni in poultry.
Computing Lower Bounds of µ-Values for a Class of Rotary Electrical Machines

In this article we present the computations of lower bounds of well-known mathematical quantity in control theory known as structured singular value for a family of structured matrices obtained for a DC Motor, that is an electrical machine. The comparison of lower bounds with the well-known MATLAB function mussv is studied. The structured singular values provide an important tool to synthesize robustness as well as analyze performance and stability of feedback systems.
Inventaritation and Potential Utilization of Macroscopic Mushroom in TPKh Tenjo KPH Bogor

The TPKh Tenjo KPH Bogor is a production forest wood collection area and becomes a production forest for the Acacia mangium wood species. Timber harvesting activities leave a lot of tree stumps, twigs, or piles of wood that do not pass production. Environmental conditions with a lot of harvested wood residue and supported by relatively cool air temperatures and high humidity, it is suspected this area has a diversity of macroscopic fungi with various unknown potentials. This study aims to obtain data on the types of macroscopic fungi and their potential uses. The research method includes the stages of exploration, identification and literature study to obtain the potential of the macroscopic fungi found. The research succeeded in finding 8 types of macroscopic fungi classified into the phylum Basidiomycota, 3 orders, 5 families, and 7 genera. The macroscopic fungi include Coprinellus sp. , Lentinus sp. , Panus sp. , Schizophyllum commune, Pycnoporus sp. , Fomitopsis sp. 1, Fomitopsis sp. 2, and Lycoperdon sp. Based on the results of the literature study, the potential uses of macroscopic fungi were found are as food, medicine, natural pigment producer, and enzyme producer. This data report can be used as basic information on the use of macroscopic mushrooms by communities around the area to be used as food or medicinal ingredients. Further utilization of this data is the development of the potential of macroscopic fungi that produce enzymes, pigments or drugs to be produced on a large scale. Research on the development of potential mushroom conservation strategies can also be carried out for sustainable use.
Partial Spatial Coupling of LDPC Codes: Reducing the Gap to Capacity by Improving the Rate

A different approach for constructing protograph-based spatially coupled low-density parity-check (SC-LDPC) codes is proposed. Instead of lifting multiple copies of an identical SC-LDPC protograph at the lifting stage of code construction, we divide the copies into fractions <inline-formula> <tex-math notation="LaTeX">$\alpha \in [{0,1}]$ </tex-math></inline-formula> SC-LDPC protographs and <inline-formula> <tex-math notation="LaTeX">$\beta =1-\alpha $ </tex-math></inline-formula> uncoupled sequence of block LDPC protographs. The permutations in the edge bundles formed by two different protograph structures follow the multi-edge-type framework. The rate loss associated with SC-LDPC codes is reduced, and we obtain code ensembles with flexible rates, by varying <inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>. We call these codes partial spatially coupled (PSC) LDPC codes, and through density evolution, we show that for data transmission over the binary erasure channel, the gap between channel capacity and thresholds of these codes is smaller as compared to SC-LDPC codes. The main bottleneck in the practical implementation of SC-LDPC codes is the rate loss. Conventionally, the rate loss can be reduced by taking large coupling length <inline-formula> <tex-math notation="LaTeX">$L$ </tex-math></inline-formula>, which however increases the decoding complexity. The proposed PSC-LDPC codes mitigate this tradeoff. Furthermore, these codes can also be decoded by the windowed decoder (WD), and through Monte Carlo simulations, we show that the WD performance of PSC-LDPC codes is better than that of SC-LDPC codes.
The Antibacterial Performance of Implant Coating Made of Vancomycin-Loaded Polymer Material: An In Vitro Study

Bacterial adhesion and biofilm formation on the surface of titanium implants are the main causes of implant-associated infection. An antibacterial coating on the implant surface can reduce the risk of biofilm formation. The aim of this study was to investigate the bactericidal effects of a van-comycin-loaded polymer coated on an implant surface. For this purpose, poly(N-isopropylacrylamide) (PNIPAAm) was first synthesized as a homopolymer or by co-polymerization with acrylamide (PNIPAAm-AAm) at a 5% weight ratio. Then, thin and uniform polymer coatings were prepared using the spin coating technique. The degree of surface hydro-philicity of the polymer coatings was evaluated by measuring the water contact angle (CA). For the antibacterial tests, the polymer-coated surfaces were loaded with vancomycin. The tests were performed in three conditions: on a glass surface (control), on a PNIPAAm-AAm-coated surface, and on a PNIPAAm-AAm-coated surface loaded with vancomycin. The death rates of the bacteria in contact with the coated surfaces were evaluated at different temperatures with fluorescence microscopy. A scanning electron microscopy (SEM) analysis of cross sections of the polymer coatings revealed a uniform thin film of approximately 200 nm in thickness. The water contact angle analysis performed at different temperatures revealed that the polymer-coated surfaces were more hydrophobic (CAs ranging between 53° and 63°) than the uncoated glass surface (CA ranging between 15° and 35°). The bacterial death rate, measured at 40 °C or while continuously switching the temperature between 37 °C and 40 °C, was higher in the presence of the surface coated with vancomycin-loaded PNIPAAm-AAm than when using the other surfaces (p-value ≤ 0.001). The vancomycin-loaded polymer coating evaluated in this study exhibited effective antibacterial properties when the polymer reached the phase transition temperature.
Pilot home zone schemes: evaluation of the Five Roads area, London Borough of Ealing

Home zones are residential areas where the built environment is designed to be places for people, not just for motor traffic. Their aim is to change the way that streets are used in order to improve the quality of life for residents including children and those that walk or cycle. A home zone allows a wide range of activities to take place in the street on space that was formerly considered to be exclusively for vehicles. Changes to the layout of the street should emphasise this change of use, so that motorists perceive they should give informal priority to other road users. Both hard and soft landscaping are appropriate. The Five roads area of Ealing is one of nine home zone schemes in a pilot programme set up by the Department for Transport (DfT). TRL was commissioned by DfT to assess the effectiveness of each pilot home zone scheme in achieving it's aims. In order to determine their impact, a comprehensive 'before' and 'after' monitoring programme was devised. This included attitudinal surveys of residents both adults and children, collection of traffic flow, traffic speed, accident data and video recording. This report presents a comparison of the results of these 'before' and 'after' surveys and reaches a conclusion regarding the impact the home zone has had upon resident's lives. (A)
Impact of the Atmospheric Non-tidal Pressure Loading on Global Geodetic Parameters Based on Satellite Laser Ranging to GNSS

Atmospheric pressure loading plays a crucial role in precise space geodesy, thus its omission, especially the nontidal loading (ANTL) part, leads to the inconsistency between solutions based on the microwave [Global Navigation Satellite Systems (GNSS)] and optical [satellite laser ranging (SLR)] observations. SLR observations are performed only during the cloudless conditions coincident with high values of air pressure that deforms the earth’s crust downward. The systematic shift of the estimated SLR station coordinates, which arises from the ANTL omission, is called the Blue-Sky effect. The offset is related to the long-term averaging of ANTL for SLR observations which are provided in sparse intervals, unlike GNSS, which observes continuously. Based on the ANTL model applied on SLR observations to GNSS, we determined the values of the Blue-Sky effect. The largest values of the Blue-Sky effect are observed for the inland stations, i.e., 2.3, 2.1, 2.0, and 1.9 mm for Svetloe, Potsdam, Baikonur, and Altay, respectively. We also investigate the impact of the omission of ANTL corrections on geodetic parameters, i.e., earth rotation parameters, geocenter motion, precise GNSS orbits, as well as on the global SLR network. The negligence of ANTL causes a systematic effect on geocenter coordinates with the amplitude of the annual signal at the level of 1.9 mm for the Z-component. The omission of ANTL corrections causes also a systematic shift of the multi-GNSS orbit constellation with the amplitude of the annual signal at the level of 2.7 mm for the Z-component.
Assessment of Soil Quality in the Transformation from Pure Chinese Fir Plantation to Mixed Broad-Leaved and Cunninghamia lanceolata Plantation in Subtropical China

To assess the alterations in soil properties resulting from the interplanting of broad-leaved tree species within coniferous forests, we conducted an investigation into soil quality in a mixed Chinese fir and broad-leaved forest, as well as in a Chinese fir pure forest (used as a control) in subtropical China. A total of 15 soil physicochemical properties were assessed across three soil depths—0–15 cm, 15–30 cm, and 30–45 cm—for the two forest types in the experimental study. Principal component analysis in conjunction with the Norm value was employed to create a minimal data set (MDS) for assessing six indicators, including bulk density (BD), total nitrogen (TN), total phosphate (TP), available potassium (AK), soil pH, and catalase (CAT). The soil quality index (SQI) was calculated for both forest types. The results demonstrated that following the interplanting of broad-leaved tree species in the Chinese fir forest, all soil physicochemical indicators were significantly improved compared to the control, and significant differences were also observed in the 0–15 cm and 15–30 cm soil layers (p < 0.05). The overall average of the SQI of the mixed forest (0.8523, 0.6636) was significantly higher than that of the control (0.4477, 0.3823) (p < 0.05) in the 0–15 cm and 15–30 cm soil layers, respectively. However, there was no significant difference in the SQI in the 30–45 cm soil layer (p > 0.05) between the two forest types. The results indicated that the SQI based on the minimal dataset (MDS) can reflect the SQI of the total dataset (TDS) when assessing soil quality in forests. Our research provides valuable scientific insights into soil science and an understanding of the relationships between soil properties, forest structure, and species composition in sustainable forest management.
When CSR Matters: The Moderating Effect of Industrial Growth Rate on the Relationship between CSR and Firm Performance

Corporate social responsibility (CSR) has become a management strategy that simultaneously pursues societal and company sustainable development. Additionally, CSR is becoming a key strategy to secure competitiveness and sustainability by improving a company’s reputation and creating new business opportunities. Thus, expectations and demands for companies’ social impacts and sustainability from various stakeholders, such as shareholders, consumers, employees, and local communities, have begun to rise. This study focused on the distinctive factor of rapid economic growth, which characterizes Korean development, and analyzed the relationship between CSR and firm performance according to the industries’ growth rates. Regression analysis was conducted through multi-level analysis using data from a sample of 102 companies that prepared sustainability reports or ESG reports in Korea; the research results are as follows. First, CSR activities have a positive impact on firm performance. Second, when CSR activities increase, the firm performance increases faster for companies in the high-growth industry group than those in the low-growth industry group. Furthermore, we conducted additional analyses to examine the moderating effect of industry growth and found that companies in the high-growth industry group had higher overall CSR levels than those in the low-growth industry group. This study’s results provide meaningful implications for understanding how CSR affects a company’s economic performance and acts as a way to strike a balance between industrial development and fulfilling social responsibility.
The effect of customer relationship management (CRM) on business profitability in Jordanian logistics industries: The mediating role of customer satisfaction

In today's competitive business environment, the implementation of Customer Relationship Management (CRM) strategies is essential for firms to succeed. The purpose of this study is to investigate the relationship between CRM, customer satisfaction, and business profitability in the Jordanian logistics industry. Specifically, the study examines how customer satisfaction mediates the effect of three key CRM on business profitability. To achieve this, Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to analyze data collected from 384 employees of logistics firms in Jordan. The results of the study suggest that CRM positively affects customer satisfaction, and that customer satisfaction has a significant mediating effect on the relationship between CRM and business profitability. The findings of this study have important implications for logistics firms seeking to improve their business profitability through the adoption of CRM. By focusing on the three key CRM (Customer Identification, Customer Acquisition, and Customer Analytics), firms can improve their customer satisfaction levels, which, in turn, can lead to improved business profitability. This study adds to the growing body of literature on CRM practices and their impact on business profitability, particularly in the context of the Jordanian logistics industry.
Multi-scale evolution of Kelvin–Helmholtz waves at the Earth's magnetopause during southward IMF periods

At the Earth’s low-latitude magnetopause, the Kelvin–Helmholtz instability (KHI), driven by the velocity shear between the magnetosheath and magnetosphere, has been frequently observed during northward interplanetary magnetic field (IMF) periods. However, the signatures of the KHI have been much less frequently observed during southward IMF periods, and how the KHI develops under southward IMF has been less explored. Here, we performed a series of realistic 2D and 3D fully kinetic simulations of a KH wave event observed by the Magnetospheric Multiscale (MMS) mission at the dusk-flank magnetopause during southward IMF on September 23, 2017. The simulations demonstrate that the primary KHI bends the magnetopause current layer and excites the Rayleigh–Taylor instability (RTI), leading to penetration of high-density arms into the magnetospheric side. This arm penetration disturbs the structures of the vortex layer and produces intermittent and irregular variations of the surface waves which significantly reduces the observational probability of the periodic KH waves. The simulations further demonstrate that in the non-linear growth phase of the primary KHI, the lower-hybrid drift instability (LHDI) is induced near the edge of the primary vortices and contributes to an efficient plasma mixing across the magnetopause. The signatures of the large-scale surface waves by the KHI/RTI and the small-scale fluctuations by the LHDI are reasonably consistent with the MMS observations. These results indicate that the multi-scale evolution of the magnetopause KH waves and the resulting plasma transport and mixing as seen in the simulations may occur during southward IMF.

on Quality and Patient Safety A Survey of the Impact of Disruptive Behaviors and Communication Defects on Patient Safety Leadership

464 Ever since the publication of the Institute of Medicine Report To Err Is Human, health care organizations have received the wake-up call that they need to address the growing concern about patient safety; several follow-up reports have documented moderate improvement, but there are still large, disconcerting gaps between what we have been able to achieve and where we need to go. To advance further we need to improve our processes, systems, and technology, and at the same time address the human factor issues that affect bedside care. We originally reported on the impact of disruptive physician behavior on nurse satisfaction and retention in 2002. The results of this research showed a significant relationship between disruptive physician behavior, poor nurse satisfaction and morale, and an increase in nurse turnover. As part of the research for this study, we searched for information on a relationship between disruptive behaviors and negative outcomes of care, but other than a few anecdotal stories, we could find no documented studies directly linking disruptive behavior to negative clinical outcomes. In an effort to address the relationship of disruptive behaviors to potential compromises in patient outcomes of care, we extended the scope of the survey to include assessment of disruptive behaviors in nurses and other health care disciplines and evaluated their perceptions and experiences as to the impact of disruptive behaviors on patient care. These studies showed a significant relationship between both physician and nurse disruptive behaviors and worrisome psychological and behavioral traits, which led to impaired working relationships hampered by intimidation, hostility, stress, frustration, loss of focus, poor communication, and reduced transfer of necessary information, all of which adversely affected patient outcomes. The Joint Commission reports in its root cause analysis of sentinel events that nearly 70% of the events can be traced back to a problem with communication. Effective January 1, 2009, The Joint Commission will require that the hospital (organization) “has a code of conduct that defines acceptable, disruptive, Article-at-a-Glance
Designing binary low IFT surfactant system using HLD concept for oil recovery

Surfactant-based microemulsion technology is widely used in tertiary enhanced oil recovery applications (EOR). The formulation of suitable surfactant system is a key success in production and economic feasibility of this technology. The middle phase or Winsor Type III microemulsions, employed for selecting appropriate surfactant system, can offer an optimal salinity at which the high oil solubilization capacity and minimum interfacial tension (IFT) or ultralow IFT (<0.01 mN/m) are obtained. By this technology, more remaining oil in the reservoir can be solubilized and mobilized which leads to an improvement of oil recovery. This study aims to formulate surfactant systems for the oil recovery through microemulsion formulation. The novel mixed anionic surfactant system of a sodium dioctyl sulfosuccinate (AOT) and an internal olefin sulfonates (IOS) with different alkyl chain lengths (C15-18, C19-23, C24-28) were used due to its mixture avoiding the surfactant precipitation. The result found that the binary mixture of AOT and (IOS C15-18 and IOS C19-23) can form the middle phase at the mixing ratios of 5:5 to 9:1 (by molar ratio) with heptane and decane. When the fraction of IOS increased in the mixed AOT/IOS system, the optimal salinity (S*) also increased. For the effects of a carbon tail length of IOS surfactant was observed that the tail length increased with decreasing the optimal salinity. The hydrophiliclipophilic deviation (HLD) for the mixed surfactant system was investigated to individually determine the K and Cc values for the IOS surfactants. The finding from this work provided a guide for surfactant selection through HLD concept to formulate microemulsion-based surfactant flooding for EOR application.
