Abstract Purpose: To report the prevalence of various forms childhood glaucomas visiting our tertiary eye care centre during a year and to describe their clinical features treatment methods. Methods: This 1-year-long prospective study included all consecutive children till 16 years age who presented us with glaucoma for first time between 1 March 2022 28 February 2023. We used Childhood Glaucoma Network Classification System classification glaucoma. Results: Of 40 (80 eyes), secondary (SCG)...
In this paper, a mathematical model based on COVID-19 is developed to study and manage disease outbreaks. The effect of vaccination with regard its efficacy percentage population vaccinated in closed investigated. To virus transmission, the system employs six nonlinear ordinary differential equations susceptible–exposed–asymptomatic–infected–vaccinated–recovered populations basic reproduction number are calculated. proposed describes for highly infectious diseases (such as COVID-19)...
Face Ageing is a method for converting person’s image into certain age group. Recent research has shown that generative adversarial networks are capable of producing artificial pictures. In the paper, conditional GAN- based model facial ageing proposed. Finally, cutting-edge “Identity Preserving” optimization strategy initiated. The suggested technique tremendous potential, as by an objective analysis photos aged and rejuvenated faces produced utilising recognition estimation technologies.
A 13-year-old girl child undergoing chemotherapy for the terminal stage of undifferentiated metastatic nasopharyngeal carcinoma presented to us with a complaint poor vision in left eye (LE). There were no complaints pain, photophobia, or watering. On examination, there was asymmetric optic disc pallor both eyes patch corneal infiltration LE that difficult attribute any obvious common pathology. The richly vascular posterior segment is well-known target ocular metastasis several malignancies....
Abdominal tuberculosis is a most common type of extra-pulmonary tuberculosis.Abdominal can occur primarily or it be secondary to tubercular focus elsewhere in the body.A total 153 samples (gastrointestinal biopsies and ascitic fluid) were processed direct microscopy, culture Amplified Mycobacterium Tuberculosis Direct Test (AMTDT) performed.Comparative analysis results was done.The overall positivity by 1.3% AMTDT 5.2%.
Presently, the brain signals are recorded by various techniques like MRI, FMRI, CT SCAN and EEG. Here we using EEG technique to record in this study. As it is a common used extensively for detection of tumours. The motive behind study examine variations two different database recordings considered; Bern Barcelona (BB), Bonn University (BU). Butterworth filter applied take out artifacts from signals. decomposition decompose denoised This helps determine necessary information, complete...
The paper deals with a delayed version of prey predator model the incorporation modified Holling-Tanner functional response in population. highlights loss population via migration and natural death rate due to age factor other reasons such as prenatal death, infection etc. also considers significance delay which is taken parameter bifurcation. Local stability analysis done it examined that important attaining system's stability. Hopf bifurcation discussed brief along bifurcated type periodic...
In the present paper, a mathematical model using non-linear differential equations depicting impact of Covid-19 on unemployment is discussed. The stability system studied and reformulated as an optimal control problem. To assess human population, two time-dependent controls are used. Providing education training job-oriented persons act first campaigning about awareness coronavirus disease self-employment business second control. Necessary conditions for derived by Pontryagins maximum...
In the present paper, prey-predator relationship is discussed using Holling type IV functional response. Modified Holling-tanner model has been considered and time delay incorporated in system which a parameter of bifurcation. The concept migration prey predator population induced along with refuge local stability analysis carried out. direction Hopf bifurcation periodic solutions investigated central manifold reduction normal form theory. It examined that plays dominant role stabilizing...
The proposed model depicts the relationship between different population groups and disease is contemplated in one population. incorporation of Holling type II functional response significant to examine dynamics amid predators, susceptible prey infected prey. system analyzed it investigated that strong migration presence predator can change dynamics. basic reproduction number acknowledged stability analysis carried out. Numerical simulation performed validate theoretical results.
