Published: August 2020

A rapid green synthesis of silver nanoparticles (AgNPs) using plant extract Solenostemo monastachyus (S. monastachyus) with silver nitrate is reported here. The formation of AgNPs was confirmed by a colour change in the plant extract from pale yellow to reddish brown and was further characterized by UV-Vis spectrophotometric, FT-IR, SEM, EDX and XRD analyses. Ag+ ions were reduced by the phytochemicals present in the extract. A characteristic single broad peak was observed at 450 nm and has been ascribed to the excitation of surface plasmon resonance phenomenon. The efficient capping and stabilization properties of the NPs were revealed by the FT-IR analysis. SEM and XRD results showed the formation of spherical shaped AgNPs with the average particle size of less than 100 nm and EDX confirmed the presence of silver in the prepared AgNPs. The antimicrobial properties of the biosynthesized AgNPs was evaluated against some selected bacterial and fungal species. The prepared AgNPs had notable antimicrobial activity against the selected bacterial and fungal species. Thus, the biosynthesized AgNPs could be a good lead for antimicrobial agent.

Published: August 2020

Many researchers have already shown that only user-based or content-based features are not enough to detect rumor in social media and for better prediction we need to consider both. In our research, we argue that the word embedding feature and sentiment score with subjectivity can also play a vital role in this detection task. Moreover, to detect the rumor at a very early stage and debunk it we may need to make the detection framework portable to legitimate users. This critical situation demands a secure implementation of rumor detection framework so that the user information used for training the prediction model can be protected from unauthorized access. In our experiment, we have also found that besides SVM, Logistic Regression and Random Forest algorithms, Artificial Neural Network and k-Nearest Neighbor can be used for rumor detection purpose where Artificial Neural Network and Random Forest outperformed (more than 90%) among all these algorithms in terms of accuracy. Other three algorithms also performed well with 80% or more accuracy level. To establish the robustness and efficiency of our proposed rumor detection mechanism, Precision, Recall, F1 Score, 10-fold Cross Validation, MCC, Confusion Matrix performance measures are used.

Three-Phase Distribution System Load Flow Analysis Using Sequence Components
Authors: Gianto Rudy
Published: August 2020

Electric power distribution system are usually unbalance. Therefore, a power flow method that can handle the three-phase configuration of the power system is needed so that the system planning and operation can properly be carried out. In the case of three-phase distribution system power flow analysis, for each system bus (except for substation bus), the voltage magnitude and angle of the three phases must be calculated. These calculations are carried out under certain loading conditions. After these voltages have been calculated, the electric power flows and losses in the distribution lines, and the substation power can also be determined. This paper proposes a new technique for three-phase distribution system power flow analysis using sequence components. The new formulation for the power flow problem in terms of sequence components is also proposed and developed in this paper. The application of sequence components has the advantage that the size of the problem can effectively be reduced, and solution to the power flow problem will be easier to find. Case study using a representative distribution test system confirms the validity of the proposed method where comparative studies between the proposed (i.e. sequence components based) method and the phase components based method are carried out.

Published: August 2020

A Traveller’s Information System integrated with traffic condition which can provide vital information to the users of the system is such a powerful tool in transportation planning. In this study, web-based multimodal advanced traveller information system was developed, which supplies information to trip makers within Akure metropolis and major cities with similar traffic condition. Traffic count was also taken on five roads which most of the transportation company’s vehicle ply so as to check for the traffic condition of the roads. The system provide information such as the available route from the origin of the traveller to his or her destination, the travel time, distance of each route, closest facilities like hotels, hospitals, airline services, airport terminal, departure time, departure time, arrival time and fare. The traffic count carried out revealed that Oyemekun road has the highest volume of traffic followed by Akure-Ado road while FUTA North gate road gives the least volume of traffic. The reason for the highest volume of traffic recorded at Oyemekun road is as a result of it location close to the CBD (Central Business District) while the lowest volume of traffic recorded for FUTA North gate is as a result of it location almost at the outskirt of the town. The web-based multi-modal traveller’s information system developed will help trip makers in Akure metropolis minimize the cost of their trips, by reducing travel time, energy consumption, and transport fare. Travellers are advised to embark on their journey earlier than the peak periods so as to avoid delay.

Published: August 2020

Numerical simulation using computational fluid dynamics has been studied broadly in various fields of applications. Along with the advancement in new technology especially those employing micro or nanoscale geometries or lab-on-chip devices, it is important to understand the efficiency of such numerical models at small geometrical scales. To access any potential error in numerical simulation using CFD, in the present work we report the investigation of capillary driven passive flow inside a channel of varying geometry. The potential error in the results of simulation at a very small scale is accessed by comparing it with the results of theoretical analysis. Hence, establishes a spatial limit of the continuum model for simulation in related applications. This gives new insight to the further study on CFD at nanometers scale geometry.
The Effectiveness of the Semi-Automatic Technique in Extracting Shoreline from Digital Elevation Models for Sustainable Development in Africa
Authors: Eboigbe Mitchell Ayemere , Ugwuoti Amos I , Sam Anthony A.
Published: August 2020

The accurate delineation of Shorelines is required to determine the respective tidal heights and monitor coastal erosion. In some coastlines, the difference between the high tide and the low tide could be as small as one meter but the accurate extraction of the respective vertical surfaces is required to understand the pattern of the sea wave energy and to chart tidal heights relative to a specific datum. The manual digitizing of shoreline is usually with high accuracies and flexibilities but could be rigorous and hectic especially for longer shorelines. Automatic extraction is more feasible where the wavelength intensity gradient within a sub-pixel level is at maximum for instantaneous shorelines with small tidal range. This is due to topological inconsistencies that could hinder such accuracies. In this study, an improved mean shift segmentation model extracts shorelines from digital elevation models from LiDAR and a UAV survey. The key element of an accurate DTM is the contouring network capable of delineating between the grid pixels each representing water and land whose elevation is below or above tidal datum. The study locations are the Freshwater and the Perranporth bay in the United Kingdom. The third is the Nigeria Maritime Academy Oron shoreline. The choice for the different study areas is to ascertain the reliability of this technique on different geographies. Comparison between manual digitizing and the mean shift segmentation were both by visual interpretation and by volumetric change analysis for two different years. The results obtained indicate that the mean shift segmentation can delineate tide-coordinated shorelines accurately. The limitation of this methodology is on digital images with poor spectral resolution. Recommendations include the use of this technique on open source GIS software and a practical solution to developing a monitoring infrastructure for coastlines in Africa.

Authors: MOHANTY VIVEK , KANT RAVI , SUDAN ADITYA
Published: August 2020

Tacrolimus is immunosuppressive agent used in a variety of skin disorders including vitiligo. Systemic Tacrolimus has been known to cause diabetes by inducing insulin resistance and increasing the activity and expression of glucose transporter , SGLT1 . In addition to this Tacrolimus has direct beta cell toxicity and subsequent insulin secretory defects. Although systemic absorption of tropical Tacrolimus is minimal but cases have been reported where tropical use of Tacrolimus has been associated with the blood levels above therapeutic range causing potential toxicity . Here we highlight a interesting case of a 22 year old female who was on treatment with Tacrolimus ointment for Segmental Vitiligo presented with features of pyelonephritis  with past history of similar recurrent episodes and on further investigations was diagnosed to have New Onset Diabetes Mellitus with elevated serum Tacrolimus levels suggesting Tacrolimus induced beta cell dysfunction and insulin resistance thus making it an interesting and rare presentation of potential toxicity.

Clinical Supervisors’ Preparedness for Clinical Teaching of Undergraduate Nurses at a University in the Western Cape
Authors: Hoffman Margaret , Daniels Felicity
Published: August 2020

Clinical supervision is crucial for the development of nursing students’ clinical competence; therefore, clinical supervisors need to be clinical experts. Inadequately prepared clinical supervisors can negatively affect clinical teaching, consequently resulting in poor clinical teaching and inadequate integration of theory and practice. This ultimately impacts patients’ health outcomes. The perceptions of clinical supervisors’ preparedness for clinical teaching were explored using a qualitative exploratory design. Semi-structured interviews were conducted with 12 clinical supervisors in an undergraduate programme. An inductive approach to data analysis generated four themes: 1) concrete experience centred on clinical supervisors’ positive experiences and challenges; 2) clinical supervisors’ application of the prescribed Skills Laboratory Methodology; 3) challenges that clinical supervisors face during clinical teaching; and 4) learning needs of clinical supervisors. The key findings highlight that although they are orientated, clinical supervisors need time to adapt and improve their knowledge and skills. The Skills Laboratory Methodology is appropriately followed. However, inadequate resources stifle the clinical teaching and learning process. Availability during teachable moments and attending to students’ clinical learning needs were regarded as important. It was highlighted that clinical supervisors require updates through attendance of workshops and in-service training. Recommendations include the need for induction and orientation programmes focusing on job expectations, roles and workload. Training sessions are required to ensure the standardisation of clinical teaching methods. There is also a need for regular meetings with stakeholders. Research is recommended to explore the coping mechanisms used to manage challenges in clinical teaching.

Published: August 2020

Prodan is a fluorescent probe used to monitor biological systems such as lipid membrane,

proteins and DNA. Remarkable interest is associated to the interpretation of its fluorescent spectrum.

In this paper the sequential hybrid Quantum Mechanics/Molecular Mechanics (S-QM/MM) method was used to establish that the fluorescent emission occurs from two different excited states, resulting in a broad asymmetric emission spectrum with two transitions. The absorption spectra in several solvents were measured and calculated using different theoretical models and they all agree that the first observed band is composed of three electronic excitation very close energetically to each other.

stevia, and the values were recorded as 4.36 - 4.99% for moisture, 7.81 - 8.91% protein,
11.37 - 17.88% fat, 1.09 - 1.24% ash and 68.65 - 73.72% total carbohydrate. The usage of
5 mL stevia solution and 3 g polydextrose to reduce 50% fat and 50% sugar resulted in
lowering 12.59% calorie content than control biscuit. Concerning sensory evaluation, a
noticeable significant difference was found among the developed biscuits at p≤0.05,
whereas all samples got acceptable scores. However, this study revealed that the
replacement of fat and sugar by polydextrose and stevia up to 50% in biscuits is
acceptable without too appreciable changes in physico-chemical and sensory properties.

Published: August 2020

Se reporta el estudio del contenido de Pb(II) en seis marcas de cervezas artesanales de la ciudad de Quito-Ecuador, utilizando Voltametría de Redisolución Anódica con Pulso Diferencial (DPASV, por sus siglas en inglés), diamante dopado con boro (BDD, por sus siglas en inglés) como electrodo de trabajo y buffer de acetato como solución electrolítica. La caracterización del BDD se llevó a cabo mediante Microscopía Electrónica de Barrido (SEM, por sus siglas en inglés) y Voltamperometría Cíclica (VC). Los resultados por SEM mostraron que la superficie de electrodos de BDD es rugosa y granular, la cual presentó una baja corriente capacitiva y una respuesta electroquímica quasi-reversible frente al par redox Ferri/Ferrocianuro de potasio. El método se optimizó en un rango lineal entre 0,3-1,3 mg L-1, se obtuvo repetibilidad con un RSD del 4,56%, reproducibilidad del 9,19% y límite de detección de 0,020 mg L-1. Las cervezas analizadas fueron etiquetadas como A, B, C, D, E y F, preservando así la identidad de las marcas que participaron en el estudio. Las muestras de cerveza B, C, D y E cumplen con la normativa NTE INEN 2262 para Pb(II) con una concentración por debajo de su límite máximo permitido de 0,1 mg L-1; mientras las muestras A y F exceden del límite máximo permisible. El método se validó mediante la comparación de los resultados obtenido por DPASV y Espectroscopia de Absorción Atómica por Llama (FAAS, por sus siglas en inglés), donde pruebas t-student indican que no hay diferencia significativa para la determinación del Pb(II) entre los métodos. Se concluye que la técnica de DPASV es una alternativa efectiva para la determinación de Pb(II) en cervezas artesanales.

Determinación del potencial nematicida y nematostático in vitro de Pleurotus ostreatus (Jacq. ex Fr.) sobre larvas J2 de Globodera pallida (Stone)
Authors: Arteaga Maria Belén , Soria Carlos A , Ordoñez Marí­a Eugenia
Published: August 2020

Globodera pallida genera pérdidas de hasta el 30 % en el rendimiento   cultivo de papa en el Ecuador.  El control quí­mico de la plaga supone riesgos de toxicidad al suelo y para el agricultor. En este estudio se determinó el potencial nematicida y nematostático in vitro del micelio en agar agua y del filtrado del caldo de cultivo de Pleurotus ostreatus en medio Sabouraud sobre larvas J2 de G. pallida. En el efecto del micelio se observó un mayor porcentaje de nemátodos inmóviles (34 %) a las 24 horas de exposición, y el efecto nematicida más efectivo a las 72 horas, con una mortalidad del 80,3 %. No existió relación entre el porcentaje de J2 inmóviles, el tiempo de exposición y la concentración del filtrado en la actividad nematostática; sin embargo, el tratamiento con 100 % de concentrado y 8 h de exposición, dio como resultado un mayor porcentaje de nemátodos inmóviles (65,2 %). El efecto nematicida del filtrado a una concentración del 100 % y 24 horas de exposición, fue la más efectiva, con una tasa de mortalidad de larvas del 41,6 %. El micelio y el filtrado de P. ostreatus presentaron actividad nematostática y nematicida in vitro frente a larvas de G. pallida.

Published: August 2020

El género Shigella comprende las especies S. flexneri, S. sonnei, S. boydii y S. dysenteriae, bacterias responsables de la shigelosis. Éste género se caracteriza por la presencia de multirresistencia a antibióticos y una variedad de factores de virulencia que permiten la infección al hospedero. El objetivo de este estudio fue establecer la sensibilidad antimicrobiana y detectar genes de virulencia “Invasion plasmid antigen H“, ipaH; “Invasion-associated locus”, ial; “Shigella toxin” Stx; “Shigella enterotoxin 1A”, set1A; y “Shigella enterotoxin 1B”, set1B en aislados clínicos de Shigella spp. Se analizaron 79 aislados obtenidos de Zurita & Zurita Laboratorios y del hospital Vozandes. Mediante serotipificación, se registraron tres especies: S. flexneri (64.6 %), S. sonnei (29.1 %), y S. boydii (6.3 %). La sensibilidad antimicrobiana siguió el método de difusión con disco según las recomendaciones del Clinical and Laboratory Standars Institute (CLSI). La resistencia obtenida fue a tetraciclina (96.20 %), ampicilina (94.9 %), trimetoprima/sulfametoxazol (86.1 %) y cloranfenicol (84.8 %). No se registraron aislados de Shigella con resistencia a ciprofloxacino, azitromicina ni a ceftriaxona. Se determinó la presencia de genes de virulencia por la reacción en cadena de la polimerasa (PCR). Se determinó una alta prevalencia de los genes ipaH (91.1 %) e ial (82.3 %), los genes codificantes de enterotoxina 1 (set1A y set1B) se encontraron en un 35.4 %. Los resultados obtenidos demuestran la existencia de multiresistencia a antibióticos y cepas virulentas.

Background

Human cases of West Nile virus (WNV) infection are recorded since 2010 in Greece, with seasonal outbreaks occurring almost annually. Enhanced surveillance has been implemented since 2010, to promptly characterise cases’ temporal and geographical distribution and inform authorities for implementation of appropriate measures (mosquito control, health education, blood safety).

Aim

We describe the epidemiology of WNV human infections in Greece focusing on the 2018 season.

Methods

The National Public Health Organization advised physicians to test all suspect WNV infection cases and refer samples to reference laboratories. Laboratories notified diagnosed cases on a daily basis. Treating physicians, patients, and infected blood donors were interviewed within 48 hours after diagnosis and the probable infection location was identified. Hospitalised cases were followed up until discharge.

Results

A total of 317 autochthonous WNV infection cases were diagnosed in 2018. Among them, 243 cases had neuroinvasive disease (WNND), representing a 23% increase of WNND cases compared with 2010, the previous most intense season. There were 51 deaths. Cases started occurring from week 22, earlier than usual. Both rural and urban areas were affected, with 86 (26% of the total) municipalities belonging to seven (54% of the total) regions recording cases. Two major epicentres were identified in Attica and Central Macedonia regions.

Conclusions

The largest number of human cases of WNV infection ever recorded in Greece occurred in 2018, with a wide geographical distribution, suggesting intense virus circulation. Enhanced surveillance is vital for the early detection of human cases and the prompt implementation of response measures.

Severe acute respiratory syndrome coronavirus 2 viral load in the upper respiratory tract peaks around symptom onset and infectious virus persists for 10 days in mild-to-moderate coronavirus disease (n = 324 samples analysed). RT-PCR cycle threshold (Ct) values correlate strongly with cultivable virus. Probability of culturing virus declines to 8% in samples with Ct > 35 and to 6% 10 days after onset; it is similar in asymptomatic and symptomatic persons. Asymptomatic persons represent a source of transmissible virus.
