Authors: Balarabe-Musa B. , Onyeagba K. D.
Published: November 2021

Amoebiasis is one of the major causes of morbidity and mortality worldwide, especially in developing countries because of lack of safe portable water and low level of hygiene. In Nigeria, amoebiasis is prevalent and widespread. The aim of our study was to estimate the prevalence ratio of E. histolytica among infants aged 1 to 59 months admitted at the University of Abuja Teaching Hospital, Gwagwalada, Abuja. The distribution of the infection was reported to relate more with inadequate environmental sanitation, poor personal hygiene and climate. The epidemiology, clinical features and causative agents of diarrhoea were investigated in 100 children aged 1-59 months visiting the University of Abuja Teaching Hospital. One hundred stool samples were collected and examined. The use of direct smear and floatation methods were employed to analyze the prevalence of Entamoeba histolytica in diarrhoeal illness across gender, age, weight and stool appearance of the patients. Out of the one hundred stool samples screened 12% were positive for the parasite. Females were more infected (12.5%) than the males (11.4%), but there was no significant association between prevalence and gender (P>0.05). Children within the age group of 1 to 12 months old had the highest prevalence rate (20.0%). There was a significant difference in the prevalence of Entamoeba histolytica among the age groups (p< 0.05). Children that weighed less than 15kg had the highest prevalence of Entamoeba histolytica (25.0%). There was a positive correlation between the prevalence and weight (p<0.05). Prevalence rate of 16.0% was recorded for watery and bloody stool. There was a positive correlation between the prevalence of Entamoeba histolytica and stool characteristics (p < 0.05). Hence this study analyzes the pattern, morbidty, occurrence and the preventibve measures to enact in tackling diarrhoeal illnesses. This study also aims to enlighten the public especially nursing mothers on the need to maintain proper hygiene in other to prevent contamination of diarrhoeal illness. Entamoeba histolytica can be a re-emerging serious infection when it finds favorable environmental conditions and host factors which are mainly attributed to poor hygiene in this study. This may occur in any area of the world with the same risk factors. Owing to the findings of this research, public health interventions such as the provision of clean water, community health education, observation of food hygiene, and maintenance of functioning sanitation systems are recommended towards controlling the infection.

Authors: Adeyemo B. T.
Published: November 2021

We evaluated the effects of dietary aflatoxin B1 (AFB ) exposure on the immune response and the 1 growth performance of Heterobranchus longifilis catfish; and determined the maximum tolerable limits for AFB in H. longifilis. Five experimental isocaloric and isonitrogenous diets amended 1 with varied concentrations of AFB [Diet A (2.0 μg AFB .kg-1); Diet B (7.3 μg AFB .kg-1); Diet C 1 1 1 (17.6 μg AFB .kg-1); Diet D (48.0 μg AFB .kg-1) and Diet E (93.0 μg AFB .kg-1)] were fed to 450 1 1 1 juvenile H. longifilis in five groups of 15 separate plastic tanks for a period or 56 days. At time points day 7, 14, 28 and day 56, five fish were randomly sampled per tank and assessed for innate immunity and growth response. Fish fed diets amended with AFB exhibited significant reduction 1 (P < 0.05) in the serum lysozyme and epidermal mucus lysozyme activity, epidermal mucus alkaline phosphatase activity and in the phagocyte respiratory burst activity. These parameters decreased with increasing concentrations and duration of dietary AFB (P< 0.05). Dietary AFB 1 1 caused significant reductions in the growth performance of juvenile H. longifilis marked by reductions in the percentage gain in length, reduction in percentage gain in weight and a reduction in the specific growth rate. Based on these results, juvenile H. longifilis catfish appears to tolerate diets containing up to 17.6 μg. Kg-1 AFB in diets.
Anthelmintic Activities (In Vitro And In Vivo) of Some Plant Extracts – A Review
Authors: Jegede O C
Published: November 2021

Several plants are found to possess potent medicinal and phytochemical compounds used globally for the treatment of diseases and the discovery of new drugs. Plants with anthelmintic properties have attained a great interest due to their usage in treatment of parasitic (helminthic) diseases that cause major economic loss, resulting to reduced livestock production capacity of farmers. The major impediment in the livestock subsector is the increasing problems of development of resistance to synthetic drugs by the helminths and or high cost of commercially produced anthelmintics and their resultant side effects than the treatment efficacy in the host. Helminthosis is a clinical condition that represents one of the commonly encountered and most important diseases in ruminant farming. This clinical condition is aggravated by indiscriminate use of anthelmintics in an attempt to control the infection, thereby causing resistance of the parasitic helminths to synthetic drugs. This has led to the screening of plant extracts for their anthelmintic properties thereby serving as alternative strategies against gastrointestinal parasitic resistance. However, eighty percent of the world populations use natural plant compounds as anthelmintics for treatment of parasitic infections. Hence, the folkloric claims of the anthelmintic properties of plants extracts for the treatment of helminthes is necessarily important and of great interest. Therefore, this review unveils previous pharmacological and preliminary studies on plants as anthelmintics able to reduce helmintic infections and overcoming helminth parasite resistance.

Prevalence of Methicillin Resistant Staphylococcus aureus (MRSA) in Cattle Milk from dairy Herds in Oyo State, Nigeria
Authors: Oludairo O. O
Published: November 2021

Methicillin-resistant Staphylococcus aureus (MRSA) has received a lot of attention in recent years as a zoonotic organism of global concern. Contaminated milk, especially those from mastitic cows, serve as reservoirs for humans in the epidemiology of antibiotic resistant MRSA. This study was designed to determine the level of contamination of bulk fresh milk from dairy cattle herds with MRSA in Ibarapa, Oyo and Oke-Ogun areas of Oyo State and the antibiotic resistance profile of the isolates. One hundred and sixty-five (165) milk samples were obtained from the study areas and used for the study. Staphylococcus aureus was isolated from the samples using bacterial culture and biochemical tests. Methicillin-resistant Staphylococcus aureus was identified using cefoxitin disk diffusion method. All the S. aureus isolates were subjected to microbial susceptibility test. Ninety (54.5%) milk samples were positive for Staphylococcus spp. out of which 52 (31.5%) were Staphylococcus aureus and 13 (7.9%) yielded MRSA. Antibiogram of S. aureus indicated highest resistance to Cloxacillin (88.5%) followed by (Augmentin 67.3%) and Ceftrazidine (67.3%). Ten out of the 13 MRSA isolates were multidrug resistance while all the isolates were 100% susceptible to ofloxacin. The results of this study showed that milk produced from dairy cattle in Oyo State was contaminated with MRSA. This portends serious food safety and public health risk among the consumers of such milk especially in raw or improperly pasteurized form. Proper dairy herd health management and prudent use of antibiotics and hygienic milking procedures are hereby recommended to prevent contamination of milk and subsequent spread of the organism to humans.
Unmanned Aerial Vehicles Traffic Management Solution Using Crowd-sensing and Blockchain
Authors: Alkadi Ruba , Shoufan Abdulhadi
Published: November 2021

Unmanned aerial vehicles (UAVs) are gaining immense attention due to their potential to revolutionize various businesses and industries. However, the adoption of UAV-assisted applications will strongly rely on the provision of reliable systems that allow managing UAV operations at high levels of safety and security. Recently, the concept of UAV traffic management (UTM) has been introduced to support safe, efficient, and fair access to low-altitude airspace for commercial UAVs. A UTM system identifies multiple cooperating parties with different roles and levels of authority to provide real-time services to airspace users. However, current UTM systems are centralized and lack a clear definition of protocols that govern a secure interaction between authorities, service providers, and end-users. The lack of such protocols renders the UTM system unscalable and prone to various cyber attacks. Another limitation of the currently proposed UTM architecture is the absence of an efficient mechanism to enforce airspace rules and regulations. To address this issue, we propose a decentralized UTM protocol that controls access to airspace while ensuring high levels of integrity, availability, and confidentiality of airspace operations. To achieve this, we exploit key features of the blockchain and smart contract technologies. In addition, we employ a mobile crowdsensing (MCS) mechanism to seamlessly enforce airspace rules and regulations that govern the UAV operations. The solution is implemented on top of the Etheruem platform and verified using four different smart contract verification tools. We also provided a security and cost analysis of our solution. For reproducibility, we made our implementation publicly available on Github
Nonlinear Analytical Model of Localized Sub-THz and THz Rectifications in FET Power Detectors
Authors: elkhatib tamer
Published: November 2021

A nonlinear analytical model for THz FET power detectors based on their distributed RC network is presented. This empirical model works well for both drain-unbiased and drain-biased THz FET responses. The physics-based analysis reveals that localized THz rectifications in long channel transistors may be mathematically expressed in the same way as regular RF frequency rectifications of a single lumped device. However, the one lumped FET model can’t work properly at THz frequencies without correct definitions of THz signals on its terminals and independently considers localized rectifications on the source and drain sides. An improved compact one lumped THz FET power detector model with additional Schottky diodes at the source and drain terminals is presented. THz FET detector can also perform a simultaneous self-amplification (active rectification) of the localized THz rectified dc signal when operates in the saturation regime beyond its unity gain frequency. A novel analytical expression for the localized THz dc rectified response is developed for FETs operating in the saturation regime. The presented physics-based model agrees excellently with the measured experimental results of GaAs HEMT transistors at 1.6THz under arbitrary biasing conditions. Many novel electronic designs can be implemented for Millimeter-wave and THz technologies based on the physical FET's nonlinear nature in this frequency range

The massive demolition of old buildings in recent years has generated tons of waste, especially brick waste. Thus, a concern of recent research is the use of this waste for the production of environmentally friendly concrete. At the same time, corrosion of the reinforcement steel rebar in classical concrete is a current problem. In this context, in the present paper a study was carried out on the corrosion of metal reinforcement in cement mortars with added brick waste. The corrosion process was analyzed on four compositions of mortars without and with 15%, 25% and 35% brick waste replacing the sand. The brick waste has majority content in SiO2, Al2O3, FeO3 and CaO. The grain size distribution of brick waste was close to that of the sand (dmax = 2 mm). The preparation method of the samples was similar to ordinary mortars. The corrosion action on the rebar in concrete, at different brick waste concentrations, was investigated by electrochemical measurements (polarization curves and electrochemical impedance spectroscopy (EIS)) at 1 month and 26 months. The results obtained at 26 months revealed that the addition of the brick waste in mortar improved the anticorrosion properties in the case of all samples compared with the etalon mortar. The best results were obtained in the case of the sample with 15% brick waste (the efficiency was ≈ 90%). The corrosion intermediary layer formed on the rebar surface was evidenced by SEM-EDX.

In recent years, immunotherapy has revolutionized the treatment of cancer; however, inflammatory reactions in healthy tissues often have side effects that can be serious and lead to permanent discontinuation of treatment. This toxicity is not yet well understood and is a major obstacle to the use of immunotherapy. When the immune system is so severely activated, the resulting inflammatory reaction can have detrimental effects and sometimes serious damage to healthy tissue. We wanted to know if there was a difference between an optimal immune response that aims to kill cancer and an unwanted response that could affect healthy tissue. Identifying the distinctive elements between these two immune responses allows the development of new, more effective and less toxic therapeutic approaches.

La re-irradiación de pacientes en radioterapia ha sido siempre un proceso complejo. Las herramientas disponibles en los sistemas de planificación de tratamiento actuales permiten generalmente el registro de imágenes y la suma las dosis administradas, pero el uso cada vez más habitual de hipofraccionamientos y esquemas de tratamiento acelerados supone que esta suma de planes sea difícil de evaluar correctamente. Esta circunstancia añade incertidumbre a la definición de volúmenes de tratamiento y la prescripción de dosis. Se ha desarrollado una herramienta para convertir las matrices de dosis de tratamiento en matrices de dosis biológica equivalente y dosis equivalente a 2 Gy por sesión. La herramienta genera archivos de dosis según el estándar DICOM, por lo que pueden ser importados en el sistema de planificación de tratamientos para evaluar la suma de planes con distintos fraccionamientos. El presente estudio describe el proceso de creación de la herramienta y analiza su posible uso clínico. Los resultados muestran una correcta alineación entre las matrices de dosis calculadas y la imagen, así como posibles limitaciones en su uso, especialmente en la evaluación de dosis a punto en los márgenes de las estructuras definidas. El uso de la herramienta es adecuado y útil para la práctica clínica pero requiere una comprensión de su  funcionamiento y limitaciones.

Se investigan las características de un detector basado en diamante sintético (PTW 60019 microDiamond) para la verificación dosimétrica de tratamientos realizados mediante arcoterapia de intensidad modulada (VMAT), para tres energías diferentes de fotones, 6MV con filtro aplanador, 6 y 10 MV sin filtro. Se contrasta su comportamiento frente a dos cámaras de ionización (PTW 31010 Semiflex, PTW 31016 PinPoint). El detector PTW 60019 presenta una respuesta estable en el tiempo, con variaciones menores a 0.31% en 7 meses. La incertidumbre típica relativa de la dosis absorbida en el punto de medida para las distribuciones asociadas a tratamientos de VMAT se estima en 3% con un nivel de confianza de 96.5% (k = 2.14). Los resultados para este detector muestran consistencia con el sistema de planificación dentro de la incertidumbre de medida en todos los casos salvo uno, mientras que las cámaras de ionización presentan diferencias por encima de 3% en volúmenes de tratamiento inferiores a 5 cm3 asociadas a inhomogeneidades en la distribución. El detector basado en diamante sintético ha demostrado su capacidad para medir dosis absorbida en distribuciones impartidas con VMAT en volúmenes de hasta 3 cm3, para haces de fotones de energías típicas usadas en radioterapia externa, sin presentar efectos de volumen o densidad significativos.

Given that managing schools to attain expected goals is becoming challenging in the present competitive society, it becomes paramount that collaborations, especially with a highly innovative group of people are encouraged. In the light of this, the purpose of this study is to investigate the extent of School-Based Management Committees' (SBMCs) involvement in public secondary school administration in Abuja. A descriptive survey design was used for the study, and 3 research questions were answered in relation to the 3 research objectives of the study. The population of the study was 460 respondents, and a sample size of 250 respondents was drawn through proportionate random and convenience sampling techniques. A structured questionnaire was used for data collection. Arithmetic mean was employed in analyzing the research questions. The result revealed among others, that the school-based management committees play a passive role in planning in public secondary schools in Abuja. It was concluded that for schools to effectively meet the academic need of the Abuja community, their collaborations with the SBMCs have to be very active and productive. To this end, SBMCs need to become more committed to collaborating and helping the schools in terms of planning, staffing and monitoring.

Face Recognition System Against Adversarial Attack Using Convolutional Neural Network
Authors: Kadhim Ansam , Al-Darraji Salah
Published: November 2021

Face recognition is the technology that verifies or recognizes faces from images, videos, or real-time streams. It can be used in security or employee attendance systems. Face recognition systems may encounter some attacks that reduce their ability to recognize faces properly. So, many noisy images mixed with original ones lead to confusion in the results. Various attacks that exploit this weakness affect the face recognition systems such as Fast Gradient Sign Method (FGSM), Deep Fool, and Projected Gradient Descent (PGD). This paper proposes a method to protect the face recognition system against these attacks by distorting images through different attacks, then training the recognition deep network model, specifically Convolutional Neural Network (CNN), using the original and distorted images. Diverse experiments have been conducted using combinations of original and distorted images to test the effectiveness of the system. The system showed an accuracy of 93% using FGSM attack, 97% using deep fool, and 95% using PGD.
