Global asymptotic stability of nonlinear cascade systems

AbstractIn this paper, we give a new, quick proof for a known result on the global asymptotic stability of continuous-time nonlinear cascade systems. Next, we state and prove a similar result for the global asymptotic stability of discrete-time nonlinear cascade systems

Patterns of plant diversity in seven temperate forest types of Western Himalaya, India

AbstractPlant biodiversity patterns were analyzed in seven temperate forest types [Populus deltoides (PD), Juglans regia, Cedrus deodara, Pinus wallichiana, mixed coniferous, Abies pindrow (AP) and Betula utilis (BU)] of Kashmir Himalaya. A total of 177 plant species (158 genera, 66 families) were recorded. Most of the species are herbs (82.5%), while shrubs account for 9.6% and trees represent 7.9%. Species richness ranged from 24 (PD) to 96 (AP). Shannon, Simpson, and Fisher α indices varied: 0.17–1.06, 0.46–1.22, and 2.01–2.82 for trees; 0.36–0.94, 0.43–0.75, and 0.08–0.35 for shrubs; and 0.35–1.41, 0.27–0.95, and 5.61–39.98 for herbs, respectively. A total of five species were endemic. The total stems and basal area of trees were 35,794 stems (stand mean 330 stems/ha) and 481.1 m2 (stand mean 40.2 m2/ha), respectively. The mean density and basal area ranged from 103 stems/ha (BU) to 1,201 stems/ha (PD), and from 19.4 m2/ha (BU) to 51.9 m2/ha (AP), respectively. Tree density decreased with increase in diameter class. A positive relationship was obtained between elevation and species richness and between elevation and evenness (R2 = 0.37 and 0.19, respectively). Tree and shrub communities were homogenous in nature across the seven forest types, while herbs showed heterogeneous distribution pattern

Hybrid Synchronization of the Generalized Lotka-Volterra Three-Species Biological Systems via Adaptive Control

Abstract: Since the recent research has shown the importance of biological control in many biological systems appearing in nature, this research paper investigates research in the dynamic and chaotic analysis of the generalized Lotka-Volterra three-species biological system, which was studied b

Abstract: In this research work, we first discuss the properties of the 3-cells cellular neural network (CNN) attractor discovered b

Study of Staphylococcus aureus Adhesion on Surface Modified Silver Coated Non-Woven Polyethylene Fabric subjected to Atmospheric Plasma treatment

This study reveals the adhesion of Staphylococcus aureus on the modified surface of silver-coated non-woven disposable polyethylene fabric used in hospitals to cover the patient’s bed.  The bacteria Staphylococcus aureus is responsible for many Nosocomial infections. Therefore, we should take action to reduce the spread of Staphylococcus aureus. The present study is focused on a nonwoven polyethylene fabric used as a bedspread that has been plasma-treated and coated in silver to prevent the adhesion of S. aureus and its growth. Non-woven polyethylene fabric is plasma-treated for quick silver adherence before being coated with silver and treated with S. aureus. Tests for fabric characterization were performed. It includes contact angle, FTIR, and SEM.SEM, FTIR, and contact angle measurements are made on the control, plasma-treated, silver-coated, and S. aureus samples. The plasma treatment will cause the fabric to enhance its surface properties. The increased surface roughness will cause the silver to adhere rapidly. The Silver will also prevent the bacteria from multiplying. Silver's antibacterial characteristics, guarantee the destruction of the germs. A bedspread made of nonwoven polyethylene fabric with a silver coating is possible. so that the sufferers can rest comfortably. The number of nosocomial infections spread by the clothing will decline. It is possible to prevent bacterial infections in the patients and medical staff

Health secrets hidden in guava leaves: Guava tea, a delicious and natural solution to treat diarrhea in children!

This study aims to increase public knowledge about the processing of guava leaves as herbal medicine to treat diarrhea. Prior to counseling and training, the results of the pretest showed that most of the participants (70.5%) had known the utilization and processing of guava leaves as herbal medicine. After attending the training, participants were given a post-test questionnaire to measure the increase in their knowledge.The results showed that there was a significant increase in the participants' knowledge after attending the training. The knowledge percentage increased from 70.5% to 89.0%, representing an increase of 18.5%. This training provides information on how to process guava leaves into herbal medicines that are effective in treating diarrhea.Some of the processing methods taught in the training include making guava leaf tea, guava leaf extract, and decoction of guava leaves. Participants were also given knowledge about the active ingredients in guava leaves, such as quercetin, which has an anti-diarrhea effect.This study showed that the counseling and training program was effective in increasing participants' knowledge about processing guava leaves as a herbal medicine to treat diarrhea. With the knowledge gained, it is hoped that the community can properly process guava leaves and use them effectively in maintaining health and treating diarrhea with simple medication. This program also empowers garden plants in the environment around the village as an easily accessible source of herbal medicines

A comparative study of dermatoglyphic markers in schizophrenia patients and normal controls

Background: Schizophrenia is a complex mental illness with multiple etiological factors. Prenatal insult to the developing foetus has been implicated as a major risk factor for the genesis of schizophrenia, according to the neuro-developmental model. As the brain and skin are ectodermal derivatives, insult to developing brain is reflected in several dermatoglyphic markers.Methods: Total finger ridge count (TFRC), Total A-B ridge count (TABRC) and ATD Angle of 100 patients diagnosed with schizophrenia were compared with 100 age and sex matched healthy controls.Results: Statistically significant differences were observed in the values recorded and compared between healthy controls and schizophrenia patients.Conclusions: This study shows the correlation between abnormalities in dermatoglyphic patterns and development of schizophrenia
