Pastes
Pastes are semisolid dosage forms containing a high percentage (50% or more) of insoluble solids dispersed in a suitable base. They adhere well to the skin and are used to treat chronic lesions. Pastes are stiffer than creams and ointments, so they remain stable at the site of application and allow perspiration to escape while not interfering with uninfected skin. Pastes are classified based on their base as fatty, aqueous gel, or hydrocolloid pastes. They are prepared by trituration or fusion and contain ingredients like zinc oxide, coal tar, or aluminum oxide dispersed in a hydrophobic or water-miscible base. Evaluation parameters include mechanical strength tests and liquid phase migration studies.

Anti dote
Poisons are substances that cause illness and death when absorbed by the body. Antidotes counteract or oppose the effects of poisons and are used to treat poisoning. There are three types of antidotes - physiological antidotes counteract poison effects chemically, mechanical antidotes prevent poison absorption, and chemical antidotes convert poisons to non-toxic compounds. Sodium thiosulfate and sodium nitrite are antidotes used to treat cyanide poisoning.
Cosmetics
This document discusses methods for evaluating various properties of cosmetic products.

Other tests include measuring volatile matter content through weight loss, powder fineness through sieve analysis, density by mass to volume ratio, and viscosity using viscometers. These evaluation parameters are important for analyzing cosmetic product composition and quality.

Colloids 1
Colloids are mixtures where particles between 1-1000 nm are suspended in a solvent. They do not separate out like larger suspensions due to their small size. There are various types of colloids depending on the state of the dispersed and continuous phases, such as emulsions, foams, and sols. Colloidal particles can be characterized by their ability to scatter light, known as the Tyndall effect. While too small to filter, coagulation methods can enlarge colloidal particles for removal. Colloids are either hydrophilic or hydrophobic depending on particle interactions with water.

Ointments are semisolid preparations meant for external application to the skin or mucous membranes. They consist of a drug substance combined with bases and adjuvants. Ointments can be classified based on their therapeutic properties and penetration, or based on their therapeutic uses such as antibiotic, anti-inflammatory, etc. The ointment base serves as a carrier for the active ingredient and must have properties such as being inert, stable, and compatible with skin. Common bases include oleaginous, absorption, emulsion and water-soluble bases. Ideal bases are selected based on dermatological and pharmaceutical factors. Ointments are prepared using methods like trituration, fusion, emulsification or chemical reaction.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
