Globally, invasive plant species Lantana camara are posing a serious threat to biodiversity in forest environments. Its ability to spread rapidly and compete aggressively with native flora has caused profound ecological imbalances, leading to habitat loss for various species and alteration of ecosystem processes. This paper aims to explore the influence of Lantana camara on forest biodiversity, examining its ecological impacts, the factors driving its invasion success, and the conservation challenges it poses. The study was conducted from February 2022 to July 2024; data was collected at a six-month interval. Using transects and plot sampling techniques, the impact of this notorious weed on the species diversity and structure was established. The invasive plant was found to cause adverse effects mostly on forb species and most nonwoody plant species, where it may result in suppression of various native plant species of communities. Lantana camara reduced the plant species densities and richness of the plant communities, with the exception of trees and climbers, where their richness and density were higher in the communities. But Shannon-Weiner diversity index shows some increases in biodiversity in an ecosystem. Therefore, sustainable control measures should be taken to eliminate and stop the spread of the invasive Lantana camara.

A new principle of origin and nature of the action of gravitational forces is proposed. Forces of universal attraction are created by ethereal vortices, therefore the forces of attraction have not centrally, but plane-symmetrical directions. This article presents evidence about the true direction of gravitational forces. On this basis, it becomes possible to revise many physical laws and paradoxes in natural science.

Needle stick injuries are serious occupational hazards in the transmission of a variety of blood borne disease, more than twenty pathogens can be transmitted through needle stick injuries including hepatitis B virus, hepatitis C virus and human immunodeficiency virus among healthcare workers. The study was conducted among staff Nurses at Indraprastha Apollo Hospitals from 1/2/24 to 29/2/2024.The objectives of the study is to assess the effectiveness of structure teaching programme on prevention of Needle stick injuries and its safety measures among Staff Nurses. Sample size of 150 staff Nurses who met the inclusion criteria were selected by non-probability purposive sampling technique. Duration of each session was 30-45minutes; pre-test knowledge level was assessed with Structured knowledge questionnaire through an online Testmoz account to fill out the questionnaire. On the 14th day of structure teaching programme post test was conducted. Data was collected and analysed by descriptive and inferential statistics. The overall post-test level of knowledge shows that, all Nurses150 (100%) had good knowledge regarding prevention of needle stick injury and its safety measures. There was a significant difference in the pre-test and post-test level of knowledge. The findings of the study revealed that the structure teaching programme was effective increasing knowledge regarding prevention of needle stick injury and its safety measures. There was a statistically significant increase in the level of knowledge after the administration of structured teaching programme. There was no significant association between the pre-test knowledge scores with the selected baselines variables.

We have recognized food and medicines thanks to successful plant experiments conducted since the beginning of time, which has led to the current state of ethnobotonical knowledge. It sheds light on the close interaction between people and plants and has shown to be very helpful in medical programs. An attempt has been made to review the literature regarding numerous ethnobotanical research conducted in the Indian state of Punjab in the current paper. Additionally, the preservation of conventional medical knowledge and medicinal plant resources is emphasized.

Calendula officinalis is a short-lived aromatic herbaceous perennial plant. According to scientific literature, Calendula officinalis can also boost wound healing activity. While the precise means it does is still unclear, it was assumed that the herb would increase the blood flow to the wound area, therefore supplying oxygen and nutrients necessary for tissue regeneration. The review's objective is to understand and explore the relevant phytochemical and pharmacological information that will enhance its effective wound-healing mechanism. The data were identified using PubMed, Google Scholar, Scopus, and bibliographic reviews of recent and old articles from an English literature search. After independent analysis by co-authors of the identified articles, data were analyzed and extracted for the stated purpose. Calendula officinalis with its high quantity of flavonoids, can help to minimize inflammation and speed up the healing process. Additional usage for Calendula officinalis is that it can be a calming ointment, wash, or tincture since it can help alleviate irritated wounds and minimize swelling and inflammation. Wound healing is a complex process, and Calendula officinalis has been historically used to treat minor wounds, skin irritation, and minor burns. Data from large comparative clinical trials are needed before routine use can be recommended. Pharmacists and clinicians can effectively address patient questions about wound care and herbal therapies to help promote wound care practices that encourage wound healing and minimize poor outcomes such as infection or scarring.
