Variation in Biofilm-Forming Potential of Staphylococcus aureus from Clinical and Non-Clinical Sources

Introduction: Biofilm forming ability has been described as a potential marker of pathogenicity, particularly in Staphylococcus aureus. These biofilms are notable as an important contributor to virulence abilities, further aiding the producing strain in long term survival and resistance to antimicrobial agents. Regional data exploring biofilm forming ability of S. aureus from various sources is limited. This study therefore set out to explore variations in biofilm-forming potential of S. aureus from clinical and non-clinical sources. Place and Duration of Study: Medical Microbiology Laboratory, Department of Microbiology, University of Port Harcourt, Nigeria from August to October 2019. Methodology: Eighty five S. aureus clinical and non-clinical isolates were studied. Biofilm-forming potential was assessed using the Congo Red agar (CRA) method which describes both the presence and degree biofilm-forming potential. Results: Majority of isolates (65.9%) did not exhibit any biofilm-forming potential using the CRA method. Biofilm-forming potential however appeared source based with 100% of non-clinical S. aureus isolates lacking biofilm-forming potential, while 58% of clinical isolates showed biofilmOriginal Research Article Otokunefor et al.; JAMB, 21(1): 1-7, 2021; Article no.JAMB. 65069 2 forming potential. A higher proportion (65.5%) of the clinical isolates exhibiting biofilm-forming potential where associated with strong biofilm-forming potential. Conclusion: This study reports a high association of biofilm-forming potential with S. aureus isolated from clinical rather than non-clinical settings. If this characteristic can indeed be used as a general marker of pathogenicity would however require more extensive studies.
A study on the effectiveness of online teaching in pharmacy education from teacher and student perspectives during the COVID-19 pandemic

Introduction: Technology is a proven teaching aid, and online teaching has facilitated teaching across borders; however although technology has been proved to be an effective teaching aid, it cannot replace a teacher. There are many reports that discuss the constraints of only using online classes, as a result the use of both online and face to face classes has been advocated. The COVID-19 pandemic, however, has forced teachers and lecturers to rely solely on online classes. Methods: The authors conducted a survey among the teachers and students of selected schools in India and in the Kingdom of Saudi Arabia to assess their experiences of the effectiveness of online teaching over traditional classroom teaching; the possible ways to improve the teaching and learning experiences; and to find innovative ways and means that can make online teaching more effective. The responses were then represented as percentages, and statistical analysis was conducted to find the degree of agreement. Conclusion: Some degree of agreement regarding focus in lectures, interactions and summative online assessments was found between students and faculties. Internet speed and technical issues were revealed to be the main constraints of this format, whereas flexibility, availability of content for revision, and fewer distractions were the positive features. The majority of the students and faculty felt that online teaching could not replace traditional face-to-face teaching. The use of animated and video content would help students’ understanding and retention of topics. Frequent summative and formative assessments are vital to draw attention, help with retention and address the issues relating to learning and teaching.

Spatial and Temporal Patterns in Macroherbivore Grazing in a Multi-Species Tropical Seagrass Meadow of the Great Barrier Reef

Macroherbivory is an important process in seagrass meadows worldwide; however, the impact of macroherbivores on seagrasses in the Great Barrier Reef (GBR) has received little attention. We used exclusion cages and seagrass tethering assays to understand how the intensity of macroherbivory varies over space and time in the seagrass meadows around Green Island (Queensland), and what impact this has on overall meadow structure. Rates of macroherbivory were comparatively low, between 0.25–44% of daily seagrass productivity; however, rates were highly variable over a one-year period, and among sites. Loss of seagrass material to macroherbivory was predominantly due to fish; however, urchin herbivory was also taking place. Macroherbivory rates were of insufficient intensity to impact overall meadow structure. No macroherbivory events were identified on video cameras that filmed in the day, indicating that feeding may be occurring infrequently in large shoals, or at night. While relatively low compared to some meadows, seagrass macroherbivory was still an important process at this site. We suggest that in this highly protected area of the GBR, where the ecosystem and food webs remain largely intact, macroherbivory was maintained at a low level and was unlikely to cause the large-scale meadow structuring influence that can be seen in more modified seagrass systems.
Go/No-Go Decision Model for Owners Using Exhaustive CHAID and QUEST Decision Tree Algorithms

Go/no-go execution decisions are one of the most important strategic decisions for owners during the early stages of construction projects. Restructuring the process of decision-making during these early stages may have sustainable results in the long run. The purpose of this paper is to establish proper go/no-go decision-tree models for owners. The decision-tree models were developed using Exhaustive Chi-square Automatic Interaction Detector (Exhaustive CHAID) and Quick, Unbiased, Efficient Statistical Tree (QUEST) algorithms. Twenty-three go/no-go key factors were collected through an extensive literature review. These factors were divided into four main risk categories: organizational, project/technical, legal, and financial/economic. In a questionnaire distributed among the construction professionals, the go/no-go variables were asked to be ranked according to their perceived significance. Split-sample validation was applied for testing and measuring the accuracy of the Exhaustive CHAID and QUEST models. Moreover, Spearman’s rank correlation and analysis of variance (ANOVA) tests were employed to identify the statistical features of the 100 responses received. The result of this study benchmarks the current assessment models and develops a simple and user-friendly decision model for owners. The model is expected to evaluate anticipated risk factors in the project and reduce the level of uncertainty. The Exhaustive CHAID and QUEST models are validated by a case study. This paper contributes to the current body of knowledge by identifying the factors that have the biggest effect on an owner’s decision and introducing Exhaustive CHAID and QUEST decision-tree models for go/no-go decisions for the first time, to the best of the authors’ knowledge. From the “sustainability” viewpoint, this study is significant since the decisions of the owner, based on a rigorous model, will yield sustainable and efficient projects.
Influence of CeO2 and Co3O(4) promoters on carbon deposition and carbon elimination over Ni-based catalysts

The influence of the addition of ceo2 or co3o4 promoter on carbon deposition by ch4 and carbon elimination by co2 over nickel-based catalysts was studied by using pulse reaction as well as bet, tga, xps, h-2-chemisorption and co2-tpsr techniques. the addition of n-type semiconductor ceo2 decreased carbon deposition activity of ch4 and increased carbon elimination ability of co2. however, the addition of co3o4 improved carbon deposition by ch4 and. resisted carbon elimination by co2. compared with ni/al2o3 catalyst, the modified catalysts ni/ceo2-al2o3 and ni/co3o4-al2o3 show no change in specific surface area and pore volume. thereby, it should be considered that there is no any relation between the carbon. deposition or carbon elimination and the specific surface area or the pore volume of the catalysts. also, the changes in particle size and metallic surface area by the adding of metal additives were not remarkable compared with ni/al2o3 catalyst. there is an interaction between active metal ni and semiconductor oxide ceo2 and the addition of ceo2 can increase the d-electron density of active atom ni, which would inhibit the migration of c-h a-electron from ch4 molecule to d-orbital of ni atom, thus decreasing the amount of ch4 adsorbed on ni sites and the extent of carbon deposition. on the contrary, in the case of co2, the electron-rich character of ni sites, which is strengthened by the addition of n-type semiconductor ceo2, is beneficial to co2 adsorption, thus leading to an enhancement of carbon elimination. metal-semiconductor interaction is the most important factor for the above phenomenon.
Pádel: una mirada compleja, dinámica y no lineal en la iniciación deportiva y el entrenamiento (Paddle-tennis: a complex, dynamic and non-linear approach for teaching-learning processes and training)

Resumen: En contraposición a perspectivas tradicionales, reduccionistas y excesivamente mecanicistas, consideramos a las/ los jugadoras/es de pádel como sistemas dinámicos y complejos, y a sus procesos de adquisición de habilidades como no lineales. El objetivo de este artículo es el de presentar las consecuencias de la introducción de las ciencias de la complejidad en el entrenamiento y el aprendizaje y mostrar aplicaciones concretas en el pádel. Tras una aproximación a conceptos clave como Constraints-led Approach, constreñimiento, auto-organización o ciclo percepción-acción, mostramos dos estudios piloto aplicables al entrenamiento del pádel donde se modifica el comportamiento a partir de la manipulación de constreñimientos de la tarea: a) Un juego reducido que escala el espacio y equipamiento para adaptarlo a jugadoras y jugadores benjamines de una escuela de pádel. Al comparar el comportamiento de las niñas y niños en juego adaptado vs. juego reglamentario, se observó que se producía un aumento de oportunidades en cuanto al número y variedad de acciones; b) El Cruzadito, un juego reducido que limita el espacio y el número de jugadores. Se comparó, en tres grupos de edad, la carga de trabajo de la situación reducida vs. juego reglamentario. Se comprobó que la intensidad fue mayor durante la práctica en el juego reducido. A partir de estos resultados, se discute sobre los beneficios de mejorar el comportamiento de los jugadores y jugadoras estimulando aspectos condicionales sin necesidad de aislar al jugador de los acoplamientos percepción-acción claves y específicos del pádel. Sugerimos que la perspectiva compleja, dinámica y no-lineal puede ser un marco idóneo para el diseño de escenarios de aprendizaje y mejora integral de deportistas. Palabras clave: complejidad, dinámica ecológica, auto-organización, emergencia, aprendizaje guiado por constreñimientos.
Harmonization Over the Regulations of Electronic Medical Records and its Potential to be Abused

The rapid development of information and communication technology has brought changes to the mechanismfor storing electronic medical records (EMR). EMR is very important to protect and provide comfort andconvenience for health services. However, it is very susceptible to be abused by hackers. This study aimsto harmonize amongst relevant laws on EMR and to identify the legal protection of EMR from abuse byhackers. This research uses a normative research method to harmonize legal norms and regulations relatedto EMR that already exist in Indonesia. Legal protection of EMR in Indonesia has not been implementedproportionally even though the regulation on EMR has been stipulated clearly in the Minister of HealthRegulation No. 269/ 2008 concerning Medical Records and various relevant Laws on it. There are noderivative laws related to EMR as mandated by the Minister of Health Regulation No. 269/2008 whichbecomes an obstacle to the effective implementation of EMR. The existence of an EMR is Also verysusceptible to be abused by hackers. So, cyber security is needed for health workers, both individually andinstitutionally to protect EMR. In conclusion, EMR has been regulated in Indonesian Laws, but it has notbeen governed into derivative laws to be implemented a proportionally. Therefore, harmonization those lawswill narrow the gaps amongst them. Further norms and regulations regarding EMR are needed to createcybersecurity which is potential to be hacked.
Research on the Effect of Monetary Policy on Financial Accelerator—Based on the empirical analysis of Chinese steel enterprises

From the perspective of principal-agent, the theory of financial acceleration holds that due to the defects of the financial market, external shocks will be amplified by the financial market and accelerate the transmission in the real economy, and the impact on small enterprises is greater than that on large enterprises. According to the theory of financial deceleration, the agency cost caused by financial friction is counter-cyclical, which restrains credit scale to some extent, prevents excessive debt, and thus alleviates external shocks. According to the empirical analysis of panel data of iron and steel enterprises and the existing empirical results of the real estate industry, it is found that there is no financial accelerator effect or financial reducer effect in the field of iron and steel enterprises. China’s financial accelerator is more focused on bubbly assets where growth is expected and continues to be overheated despite policy tightening. That would trigger a bigger debt crisis and greater economic volatility.

DESIGN OF LOW PROFILE MULTIBAND REFLECTIVE POLARIZATION CONVERTER FOR BOTH LINEAR AND CIRCULAR POLARIZED WAVES

This paper presents a multifunctional metasurface based reflective polarization converter, to convert the polarization of incident electromagnetic wave in three adjacent frequency bands. In the first band linear to circular polarization conversion and in the remaining two bands linear to orthogonal polarization conversion is achieved. The designed metasurface consists of two circular split rings and a star-shaped split resonator which is fabricated on a metal-backed dielectric substrate. From the simulation results, it is evident that the orthogonal linear polarization conversion band is observed at 9.2 GHz and 12.8 GHz with a polarization conversion ratio of more than 92%. Similarly, it is identified that the same metasurface converts the incident linear polarized wave to circularly polarized wave at 7.3 GHz. Furthermore, the proposed metasurface maintains the handedness of the circularly polarized incident wave at 9.2 & 12.8 GHz frequency upon reflection. The proposed multifunctional polarization converter has a simple planar geometry and low profile which can be used in many applications, such as reflector antennas, imaging systems, remote sensors, and radiometers.

Clean Bandwidth Improvement of MPWM Encoding Method for RF All-Digital Transmitter

In radio frequency (RF) all-digital transmitters (ADTs), pulse encoding methods are often used to generate the RF signal of one or several bits, which introduces a large amount of quantization noise (QN). The QN results in a limited clean bandwidth (CBW), which increase the design difficulty of the analog filter significantly. To solve this problem, an optimized mapping pulse width modulation (MPWM) encoding method is presented in this brief. Based on the QN analysis, the concept of noise figure (NF) for MPWM is introduced. Meanwhile, the formulae of the intermedia frequency (IF) and RF QN power in CBW are derived. Then, in the mapping of the IF signal to the RF pulse, the optimized RF pulses are searched by the NF calculation and comparison. Experiments results show that, compared with original MPWM method, the CBW of proposed method is increased by more than 3 times, and it is superior to the other reported approaches.
