1) The document presents an overview of Quality by Design (QbD) in pharmaceutical development. It defines QbD, compares the current and QbD approaches, and outlines the benefits, objectives, and elements of QbD.
2) The key elements of QbD discussed are defining objectives, determining critical quality attributes, risk assessment, experimental design, control strategy, and continuous improvement. Ishikawa and risk assessment methods are also summarized.
3) Implementing QbD provides quality medicines to patients, production improvements for manufacturers, and greater confidence for drug regulators by ensuring predefined product quality objectives.
The pharmaceutical Quality by Design (QbD) is a systematic approach to development that begins with predefined objectives and emphasizes product and process understanding and process control, based sound science and quality risk management.
QUALIFICATION OF UV-VISIBLE SPECTROPHOTOMETER, FTIR, DSC, HPLCAnupriyaNR
Analytical method qualification consists of a simplified evaluation of a subset of validation characteristics with a goal to demonstrate that an analytical method is scientifically sound and suitable for its intended use. In contrast to validation, analytical method qualification is performed without predefined acceptability criteria. Qualification may be performed as a prerequisite to method validation, or when an assay for product knowledge has not yet been established as a test for a critical product quality attribute. Qualification of equipment is pre-requisite for validation of the process in which the equipment is being used. Many types of equipment have measuring devices on them. Calibration of measuring devices is a part of qualification. Calibration of measuring devices is important, as the data is often collected through them. If the data collected is not from measuring devices that have been calibrated, the data cannot be relied upon. Thus the whole validation exercise can be questioned.

A Review on Quality by Design and its Approachesijtsrd
The Pharmaceutical Quality By Design QBD is a systematic approach to the development that starts with the predetermined objectives and is based on the process of understanding process processes and process control, sound science and quality risk management. Quality Design QBD has been created to increase the assured of providing safe, effective medicines to customers and promised to make significant improvements in product quality performance.

Pharmaceutical Quality by Design (QBD) is a concept introduced by the International Conference on Harmonization (ICH) Q8 guideline, as a systematic approach to development that begins with predetermined objectives and emphasizes the understanding of production and processes and process control, based on sound science and quality risk management.
The basic concept of QBD is “The Quality cannot be tested into the product, but it should be built into it.”
“Current Approach of Quality by Design” An Overviewijtsrd
In this Analysis, well look at how QbD is being practised right now. QbD represents a cutting edge methodology for enhancing the safety and efficacy of pharmaceuticals. Quality by Design QbD is a relatively new idea in the pharmaceutical industry, but it has quickly become an integral aspect of the current approach to quality. Quality by Design relies on the ICH Guidelines as its basis. Guidelines Q8 for Pharmaceutical Development, Q9 for Quality Risk Management, and Q10 for Pharmaceutical Quality Systems from the International Council for Harmonization ICH served as inspiration for this document. QbD is the most effective method now available for improving the quality of all pharmaceutical goods, but it poses a significant problem for the pharmaceutical business, whose procedures are traditionally static. Eventually, despite inevitable process and material variation, It is crucial to establish the desired product performance profile Target product Profile TPP , Target Product Quality Profile TPQP and to pinpoint the attributes of quality that are most important to the products success throughout the QbD process CQA . We may then use this information to tailor the products composition and production method to those characteristics. This results in the identification and management of sources of variability and an understanding of the effect of raw materials critical material attributes CMA and critical process parameters CPP on critical quality attributes CQAs . To which the process and technique of development must have access. Quality by Design QbD encompasses the processes of drug development and manufacturing. that guarantees the product meets the standards set out in advance. R. Kavi Bharathi | R.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Risk assessment consist of the identification of hazards and analysis
an evaluation of risk associated with exposure to those hazards.
Principle of management are:
• Scientific knowledge based evaluation of the risk to quality which
eventually link to the protection of the patient.
• Adequate effort should be taken; formality and documentation of
the quality risk management process should be done with the level
of risk involved
• It is joint responsibility of quality unit, business development,
engineering, regulatory affairs production operations, sales and
marketing, legal, statistics and clinical department.
07-12-2019 18
19. Methods of Risk Assessment
Methods of risk assessments are mentioned in ICH guideline Q9as
follows:
• Failure mode effects analysis (FMEA)
• Failure mode, effects and critically analysis (FMCEA)
• Fault tree analysis (FTA)
• Hazard analysis and critical control points (HACCP)
• Hazard operability analysis (HAZOP)
