ONT-3 discusses chemical disinfectants and their uses. It provides 3 types of disinfection: prophylactic disinfection which includes sterilization methods like chlorination; therapeutic disinfection to treat infected tissues; and terminal disinfection during and after patient care to disinfect surfaces. Common chemical disinfectants discussed include chlorine, iodine, phenol, heavy metals like mercury and copper, and alcohols. Physical methods like heat and radiation are also mentioned.
Endocrine System.pdf
The document summarizes key aspects of the endocrine system. It describes the main endocrine glands and hormones they secrete, including the pituitary gland, thyroid gland, adrenal gland, pancreas, ovaries, and testes. It provides details on hormones like growth hormone, thyroid stimulating hormone, adrenocorticotropic hormone, follicle stimulating hormone, luteinizing hormone, and antidiuretic hormone. It also discusses disorders of the pituitary gland such as gigantism and acromegaly.
Urinary System.pdf
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.

Reaction of anthracene
The document summarizes reactions of naphthalene, anthracene and phenanthrene. It discusses oxidation, reduction, addition and electrophilic substitution reactions of naphthalene. For anthracene, it describes its synthesis via Friedel-Crafts reactions and Diels-Alder reactions. Electrophilic substitution reactions of anthracene are also outlined. Phenanthrene synthesis is explained using Haworth and Pschorr syntheses.
Semi solid dosage forms
This document discusses semi-solid dosage forms, including their definition, advantages, disadvantages, and ideal properties. It describes various types of semi-solid dosage forms such as ointments, pastes, creams, gels, and foams. It covers the ingredients used to prepare these forms, such as bases, preservatives, emulsifiers, and antioxidants. It also discusses factors that influence drug penetration through the skin from these dosage forms and different preparation methods for ointments specifically, including incorporation, fusion, and chemical reaction methods.

drying-210615034632.pdf
Drying is defined as the removal of liquid, usually water, from a material through the application of heat. It is commonly the last stage of a manufacturing process. There are a few key differences between drying and evaporation - drying typically involves removing small amounts of water from solids, while evaporation removes larger amounts of water from liquids. Some common equipment used in drying include drum dryers, spray dryers, tray dryers, fluidized bed dryers, vacuum dryers, and freeze dryers. Drying has several important applications and benefits, such as preserving products, preparing bulk drugs, improving product handling characteristics, and achieving uniform particle size and flow.
distillation-191227021008.pdf
Distillation is a process that separates mixtures into their component parts based on differences in their boiling points. It involves vaporizing a liquid mixture and condensing the vapor to obtain purified fractions. There are several types of distillation processes that can be used for applications like purification of organic solvents, separation of drugs and petroleum products, and recovery of volatile oils and solvents. Key distillation types discussed in the document include simple, fractional, steam, molecular, and falling film distillation. Each type has slightly different equipment setup and operating principles for achieving separation of mixtures.

distillationbyankitayagnik-180430073733.pdf
Distillation is a process that separates components of a liquid mixture based on differences in their volatilities in heating and cooling processes. It involves selectively boiling the more volatile components by heating the mixture and then condensing the vapor.
There are several types of distillation including simple distillation, fractional distillation, steam distillation and vacuum distillation. Simple distillation is used to separate components with large differences in volatility, while fractional distillation allows separation of mixtures with components of similar volatility by conducting multiple distillation steps. Distillation finds applications in purification of solvents, separation of essential oils, and production of alcoholic beverages and petroleum products.
Evaporation
The document discusses different types of evaporation equipment used in pharmaceutical manufacturing. It describes evaporating pans, evaporating stills, horizontal tube evaporators, vertical short-tube and basket evaporators, long-tube climbing film evaporators, forced circular evaporators, and multiple effect evaporation. The document also covers factors that affect evaporation and problems that can be encountered with evaporator accessories.
Qualitative test for phenol .pptx
The document describes 5 qualitative tests used to detect phenols:
1. Litmus test detects phenol's acidity by changing blue litmus to red.
2. Ferric chloride test produces different colored complexes with different phenols.
3. Liebermann's test produces a yellow compound then blue or red colors.
4. Bromine water test causes bromine color to disappear and a white precipitate to form.
5. Phthalein dye test produces different colored compounds with phenols and bases.

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.
