Authors: Solanki Vikas , Dongre Atul , Nayak Chitra
Published: November 2023

Introduction:

Facial pigmentation is a common presentation of patients attending dermatology out patient department (OPD) and is of great concern to patients. Facial pigmentation may be multifactorial and is only rarely diagnosed accurately by a detailed history and clinical examination. Pigmentary disorders cause psychological distress and negatively impact the quality of life of an individual.

Aims and Objectives:

(1) To study different dermoscopic patterns in facial melanosis. (2) To estimate the frequency of different dermoscopic patterns.

Materials and Methods:

Patients with facial hyperpigmentation attending the dermatology OPD were recruited after taking their written consent. A detailed history was taken to collect demographic data. Clinical examination and dermoscopy were done in all patients. Biopsy was done as and when required. Descriptive statistics has been used to describe the quantitative data. Qualitative data were presented as frequency and percentage for clinical and dermoscopic patterns.

Results:

The study included 100 patients with 15 different facial melanoses. The most common age group affected was 21–40 years in 53 (53%) cases. The female-to-male ratio was 1.63:1. Melasma was reported as the most common cause of facial melanosis constituting 49 (49%) of the total cases. Out of the total melasma cases, epidermal melasma constituted 22 (45%) cases, dermal melasma constituted four (4%) cases and mixed melasma constituted 23 (47%) cases. Other cases included were lichen planus pigmentosus (14; 14%), facial acanthosis nigricans (14; 14%), periorbital hyperpigmentation (7; 7%), post-inflammatory hyperpigmentation (4; 4%), exogenous ochronosis (2; 2%), lentigines (2; 2%), frictional melanosis (2;2%), and one case each of Becker’s nevus, nevus of Ota, olanzapine-induced hyperpigmentation, Riehl’s melanosis, macular amyloidosis, and tanning.

Conclusions:

Melasma was reported as the most common cause of facial melanosis. The most common dermoscopic feature was accentuated pseudopigment network. The study is beneficial in understanding the different clinical and dermoscopic patterns of facial melanosis, thus helping the physician to effectively manage the conditions and reduce the need of biopsy.

Limitations:

(1) A small sample size. (2) Histopathological correlation was not done in all cases.

Authors: Rafi Sahiba , Budania Anil , Bhardwaj Abhishek , Singh Saurabh , Bains Anupama , Benny Benetta , Alam Afroz , Karthick Kannan , Agarwal Akriti , Pathania Yashdeep
Published: November 2023

Background:

Hirsutism is the presence of excessive terminal hair on androgen-dependent sites of the body. Lasers like Alexandrite, diode, and Nd:Yag lasers have been used for hair reduction with varying efficacy. Trichoscopy of hair is a simple noninvasive method of hair assessment. However, it has not been used in the assessment of diode laser hair reduction.

Objectives:

This study aimed to assess the efficacy and safety of diode laser hair reduction in skin color with the help of clinical and trichoscopic assessment.

Materials and Methods:

This prospective observational study included 73 patients of hirsutism recruited in 18-month period. All participants received sessions of 805 nm diode laser at monthly intervals up to six sessions. Clinical and trichoscopic evaluation along with photographs were obtained at each visit. Side effects, if any, were noted in every sitting.

Results:

All patients were females of Fitzpatrick skin types III–V. All clinical parameters showed statistically significant hair reduction when compared with baseline. Trichoscopic parameters of hair reduction like total hair count, terminal hair count, and terminal/vellus hair ratio showed reduction compared to baseline which was statistically significant (P < 0.05). The most common side effect noted in our study was pain followed by erythema and perifollicular edema.

Conclusions:

Diode laser is an effective and safe procedure for the reduction of unwanted facial hair, even in darker skin types. We also wish to emphasize that trichoscopy for the assessment of laser hair reduction is a recent, noninvasive, simple, and underutilized tool. No serious adverse events were noted in our study.
Orbital apex squamous cell carcinoma
Authors: Lim Y J K , Tham C A
Published: November 2023

A middle-aged lady was referred to the Otolaryngology department for consideration of an endoscopic biopsy of a mass located in the right orbital apex. She had initially presented to the eye clinic with complaints of right proptosis and worsening vision. Upon examination, her right eye showed no perception of light, an amaurotic right pupil, and limited extraocular movement in all directions of gaze. Hertel's ophthalmometer revealed proptosis, and there was a loss of corneal sensation. Magnetic resonance imaging (MRI) of the orbits revealed an enhancing mass in the right orbital apex, extending into the cavernous sinus. She subsequently underwent an endoscopic trans-sphenoidal biopsy of the lesion. Histopathological analysis confirmed the pre- sence of squamous cell carcinoma (SCC). Further systemic evaluation did not reveal any other primary site or metastasis. Conside- ring the unresectable nature of the tumor and her poor candidacy for chemotherapy and radiotherapy, the patient was managed with best supportive care.

Published: November 2023

The present study evaluated the synthesis of iron oxide nanoparticles using Spermacoce ocymoides Burm.f. plant extracts, and the effects of plant based iron oxide nanoparticles on A549 lung cancer cells were investigated to elucidate their impact on cellular morphology, mitochondrial function, and apoptotic pathways. Spermacoce ocymoides plant based iron oxide nanoparticles were characterised by X-ray diffraction, Atomic force microscopy, FTIR, and UV-Vis absorption spectroscopy. Iron oxide nanoparticle treatment caused considerable morphological alterations in A549 cells, including cell shrinkage, detachment, membrane blabbing, and distorted shape, consistent with cellular stress and potential apoptotic events. MMP analysis revealed a dose-dependent decrease in mitochondrial membrane potential, implying that nanoparticles have an effect on mitochondrial function. The presence of reactive oxygen species suggested that oxidative stress was involved in the cellular response to iron oxide nanoparticles. Additionally, DNA fragmentation analysis confirmed the activation of apoptotic pathways, with the nanoparticles themselves serving as a positive control for inducing apoptosis. The observed morphological changes, altered mitochondrial function, ROS production, and DNA fragmentation collectively point towards apoptotic cell death pathways being triggered by the nanoparticles.

Published: November 2023

This study examines the physicochemical properties and corrosion resistance of hydrothermally produced copper oxide-reduced graphene oxide nanocomposite (CuO/rGO). The CuO/rGO nanocomposite has a well-defined and homogeneous structure, decreased crystal size, and uniformly distributed CuO nanoparticles tethered to the rGO. X-Ray diffraction confirms the fabrication of 15.1 nm crystalline monoclinic CuO nanoparticles. EDX confirms the composite's composition by detecting Cu, O, and C components. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (LSV) tests evaluate the CuO/rGO nanocomposite's corrosion resistance. A mild steel plate under an HCl electrolyte with corrosion in the PPM ratio treats the nanocomposite-coated substrate. The composite's synergistic effect is assessed by comparing its corrosion performance to CuO/rGO concentrations in ppm. The corrosion resistance data demonstrate that the CuO/rGO composite improves with inhibitor concentrations of 0, 25, 50, 75, and 100 ppm. Adding rGO to the composite protects it and speeds up charge transfer, reducing corrosion and improving stability. The composite's synergistic effect of CuO and rGO provides excellent corrosion resistance regardless of concentration, making it a viable material for corrosion-prone applications. The research develops novel and effective anti-corrosion methods to preserve materials in the food, automotive, and large-scale energy industries.

KEY WORDS: CuO/rGO nanocomposite, Tafel plot, Corrosion protection, Surface analysis

Optimization of parameters for bio-ethanol production from sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice and finger millet malt using Taguchi method
Authors: Okoth Dolphene , Otieno Stephen , Kiema Francis , Onyango David , Kowenje Chrispin
Published: November 2023

Bio-ethanol is a promising renewable energy but its production is expensive from high cost of feedstocks. In this study, sweet sorghum (Sorghum bicolor (L.) Moench) stalk juice was investigated for bio-ethanol production. Most reports on bio-ethanol productions use commercial Saccharomyces cerevisiae as yeast. However, this study used finger millet (Eleusine coracana) malt with already high adaptation to local conditions and high economic viability as it is being utilized by the indigenous communities. Five sweet sorghum varieties of IESV-92001-DL (V1), NTJ (V2), 15233-IESV (V3), 92008-DJ (V4) and IESV-92028-DL (V5) were planted at 0°3'45.4644" North, 34°17'16.1052" South, in Kenya. °Brix content of juice was determined at 11th to 16th weeks after sowing. Highest °Brix for all varieties were at 15th week where V1 was highest at 22.07. V1 was then harvested for the juice. Factors affecting fermentation; temperature, time, pH and yeast to substrate ratio were optimized using Taguchi method and were obtained as 30 ℃, 48 hours, pH 5 and 5 g/L, respectively. Kinetics parameters of Vmax and Km were 0.35 g/L/h and 12.56 g/L, respectively. The optimized and kinetic parameters were within literature values and therefore finger millet malt has a great potential, as a substitute yeast source, in commercial bio-ethanol production.

utilisation of mobile technologies in outreach services at the National Archives of Zimbabwe
Authors: Nduna Victor , Rodrigues Antonio , Schellnack-Kelly Isabel
Published: November 2023

This article focuses on investigating the utilisation of mobile technologies in outreach services at the National Archives of Zimbabwe (NAZ). The study adopted a case study strategy anchored on an interpretivist paradigm. Data were gathered from interviews with a purposively selected maximum variation sample of NAZ staff members and from relevant primary documents and physical artefacts. The collected data were thematically analysed and presented in accordance with the research objectives. The findings established that staff were aware of and keen to adopt mobile technologies for outreach purposes. However, negative conditions at NAZ such as limited access to the internet, lack of a clear policy, equipment, and technical support hindered mobile technology adoption for outreach purposes. The study established that the disparity between staff awareness levels and institutional preparedness influenced staff members’ adoption of mobile technologies outside official channels. As such, mobile technologies used in outreach services at NAZ were ad hoc. Overall, the study established that mobile technology utilisation at NAZ was in the elemental stages, where use variety, breadth and intensity were constrained. The study recommends that NAZ should craft a policy to regulate and institutionalise the use of mobile technologies for outreach purposes, and upgrade their ICT facilities.
CoMoSAOVA: Computational model for sentiment analysis and online visibility assessment
Authors: Ejodamen P.U. , Ekong V.E. , Asuquo D.E.
Published: November 2023

The online visibility of a brand, product or organization could influence customers’ decision to patronize it. Online reviews are opinions or emotions of customers that reveal their perception about the product over a period of time. The manual identification of features and sentiments toward an entity is a difficult task. In this study, a computational model was proposed to measure online visibility by mining Twitter data on discourse about a corporate entity – University of The Gambia. The numbers of Twitter posts, followers, followings, likes, retweets, quotes, replies and mentions serves as metrics for online visibility assessment. A linear regression evaluation between the age of the entity’s account and the number of its followers showed 96.81% correlation. This shows that the older an active Twitter account, the higher the  chance of increasing its  followers and its visibility. Another section of the model predicts the tweet sentiment of the  entity’s followers with an  accuracy of 93.68% using support vector machine and multilayer perceptron neural network.  The computed average  sentiment score of the case study was 0.3531996 based on Valence Aware Dictionary of  sEntiment Reasoning (VADER)  model. This means that positive sentiments were expressed in discussions on various  issues where the entity was mentioned.  The model will enable decision makers understand the sentiments expressed  towards an entity. It also estimates online  visibility of the entity based on its number of followers and the accounts’  lifespan. The perceived sentiments will aid better  decisions that could advance loyalty to the entity. Future studies  would examine other computational models to predict  various Twitter features that increases an entity's online visibility.

Authors: Adegoke A.A. , Ben U.C. , Fatunla O.K.
Published: November 2023

Bacteriocin from lactic acid bacterium (LAB) was characterized and its biopreservation assay carried out using conventional  methods and integrative approaches. About 66.7% (n=180) of the bacterial strains isolated from twelve different  fermented/non-fermented food products were potential LAB strains by biochemical characterization. The  highest bacteriocin  producing strain was selected and confirmed with 16S rRNA sequencing and submitted to GenBank  of National Center for  Biotechnology Information as Lactiplantibacillus plantarum strain Y11 (Accession number:  MW642245.1). Polymerase  Chain Reaction (PCR) revealed the presence of virulence genes (cytotoxin K and haemolysin  C) in L. plantarum Y11. The  bacteriocin produced was labelled as plantaricin Y11 with molecular weight of 1540 Da,  amino acid sequence was  NSHGTADYCVMWLIXK, and possessed the merits of wide pH stability (2–10), high thermal  stability and sensitivity to  protease. The bacteriocin showed wide spectrum of activity against bacterial reference strains  with bacteriocin activity  ranging from 3200Au/mL to 6400Au/mL. Preservative potentials of the bacteriocin  compared favourably with sodium benzoate in milk, inhibiting bacterial and fungal load compared to the control. There  was log reduction of aerobic mesophilic bacterial count of 8.02±0.15 and 8.43±0.21 Log 10 CFU/mL in milk treated with  plantaricin Y11 and sodium benzoate,  respectively. The log reductions of fungal count in plantaricin Y11 and sodium  benzoate treated milk ≥4.41±0.11 and  ≥3.1±0.2 Log 10 CFU/mL respectively. The plantaricin Y11 was then classified as  class IIa in bacteriocin classification  schemes and it sustained some organoleptic conditions of milk making it a  promising candidate for safe bio-preservatives.

Published: November 2023

Having a mixture of similar items that needs to be separated for processing or for storage is a common challenge. Dalium guineense (DG) is a wild fruit with epicarp that could be broken accidentally or intentionally during harvest or in  the course  of processing. This research attempts to develop a model for classification of DG fruits into whole fruits and  deshelled fruits each with fifteen physical characteristics (Length (l), width (w), thickness (t), geometric mean diameter,  arithmetic mean  diameter, specific mean diameter, equivalent mean diameter, surface area, aspect ratio, surface area, sphericity, unit mass,  lw (product of length and width), lt (product of length and thickness) and wt (product of width and thickness)) using a machine learning approach. A 15-3-2 Neural Network (NN) architecture was used to develop the classification model. The deshelled fruits were all correctly classified while 95 of the whole fruits were correctly classified with 5 of the fruits misclassified. The result shows that the classification model was able to achieve an accuracy of 97.5%, sensitivity of 100%, and precision of 95.2%. Increasing the number of processing elements in the hidden processing layer of the NN contributed no positive effect on the performance of the model. This model is therefore suitable for classification purpose, leading to appropriate processing and handling of DG with high accuracy.

El presente estudio aborda las relaciones entre la clasificación y la movilidad funcional a la luz de los elementos vertebradores del encuadramiento y las transformaciones materiales operadas en el mismo. La clasificación constituye un todo orgánico cuya ordenación depende de cada sustrato organizativo, recabando con ello un amplio abanico de elementos clasificatorios. La ley 3/2012 reformó esta materia entronizando al grupo como categoría omnisciente (ex arts. 22 y 39 ET), sin embargo, la realidad material y profesional vertebra la clasificación con una amplia variedad de elementos referenciales. Por otra parte, una defectuosa ordenación de las categorías tensiona, por fuerza, las facultades empresariales imbricadas en la movilidad funcional y el instituto modificativo. Lo cual justifica el análisis de esta temática desde esa óptica integradora y sistémica.

Published: November 2023

Marjan fields west of Kifl, represent the underground geological structures that contain oil-producing reservoirs in central Iraq. The objective of this study is to identify the most important acquisition criteria that can design an optimal 3D reflection seismic survey to obtain high-resolution seismic images of four major reservoirs. Hartha, Zubair, Najma, and Churra chine in Marjan fields, west of Kifl as oil reservoirs within the study area, for which a three-dimensional design is required. Generally, it is found that a specific container size of 25×25 m is suitable for sampling the field of the reflected waves in the study area. The group interval and the survey resource interval determined this size of 50 m was adopted for the time interval of the source and receiver. A dip of 30, and a maximum frequency of 70 H, were used to create the survey design. The migration aperture is calculated using the variation of velocity with depth and is 2450 m. All these computational and statistical parameters were performed using MESA Expert v11.02 software.
The Cause of the Earthquake (4.7 mb) and Recent Stress Regime Occurring in Al-Refaei Area, Mesopotamian plain, August 18th, 2017
Authors: Ramthan Ali
Published: November 2023

Al-Refaei area is considered one of the highest seismically activity in the Mesopotamian Plain according to its seismic history. Depending on the International seismological Center, four seismic swarms were diagnosed in this area; these are: August 2004, January 2013, May-Jun 2017, and August 2017. Based on three focal mechanism solutions of magnitude greater than 4 mb, the stresses in the area were analysed. The results of focal mechanisms suggest that the faults movements in the study area show reverse movements, which is generated by compression force. To determine the directions of principal stress axes that affecting the faults in the area, the Rotational Optimization method were used. The directions of the three stress axes are: 02°/32°, 10°/302°, and 80°/136° for σ1, σ2, and σ3, respectively. The collision between the Arabian and Iranian plates is the main cause of seismic activity in Al-Refaei area. Therefore, Al-Refaei active fault is responsible for most the earthquakes in the area, and responsible for the earthquake that occurred in August 18th, 2017.

Dismantling Structural Racism in Organisational Systems
Authors: Freeth Rebecca , Akpan Akanimo , Sonday Mahmood
Published: November 2023

Globally, our societies are riddled with racism and so are our organisations. While there are many excellent “Diversity, Equity, and Inclusion” (DEI) practitioners tackling racism and promoting racial equity in organisations, we contend that the language of “diversity” and “inclusion” risks diluting the impact of this work. Something stronger may be required to address racism’s tenacious structural character. We propose thinking about this work in organisational systems as more fundamentally “dismantling structural racism.” The dismantling process can be enabled by having a fuller understanding of what structural racism is, and how it affects people working in organisations, as well as by having a deeper appreciation of the history of racism, rooted in colonialism, and serving the ends of economic exploitation. With this greater awareness of how racism is built into, and manifests, in organisational systems, we are better equipped to act in more systemic ways towards dismantling it. In this article, we share some of what we are learning about convening and engaging in organisational systems with the purpose of navigating both structural and cultural change.

Published: November 2023

In March 2023, one hundred and sixty leaders and change-makers from fourteen countries across Latin America participated in a four-day gathering held by the Presencing Institute called the Ecosystem Leadership Program (ELP) in Latin America.
