This PDF file content is about complexation and Protein bindings as per the PCI syllabus for B.Pharm Second year for the subject Physical Pharmaceutics
Organic compounds are almost 60% of all compounds. because of carbons tendency to form a compound as it has more than1 electron(4electrons) to form covallent compounds. SO a wide range of everything we eat is formed from carbon and hydrogen, which is the second important element to form organic compounds.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne

All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

8. Ionic Bonds – when an atom loses or gains one or more electrons, it becomes positively or negatively charged – an ION. A positive ion is called a CATION and a negative ion is called an ANION. Sodium (Na) has 11 e, only one in the outer shell, so it tends to be an electron DONOR. Chlorine (Cl) has 17 e, and its outer shell has 7 e, so it tends to be an electron ACCEPTOR. When a Na atom and a Cl atom come together, an electron is transferred from the Na atom to the Cl atom. Now both have 8 e in their outer shell.
9. Covalent Bond – when two atoms share one or more pairs of electrons this called a covalent bond. E.g., H has 1 e in the outer shell so it can accept 1 more e. A H atom can share with another H atom. Because they share the electron pair, each atom has a completed outer shell. H—H or H 2.
10. Oxygen – oxygen has 6 electrons in the outer shell, so atoms share 2 electrons to make a total of 8 electrons. Thus a double covalent bond. Nitrogen – nitrogen has 5 electrons in the outer shell so atoms share 3 electrons to make a total of 8 electrons. Thus, a triple covalent bond.
15. Oxidation-Reduction Reactions Oxidation – the reactant losing the electrons is referred to as the electron donor and is said to be oxidized. Reduction – the reactant taking up the transferred electrons is called the electron acceptor and is said to become reduced. Redox reactions occur when ionic compounds are formed. E.g., NaCl – Na is oxidized and Cl is reduced E.g., Cellular Respiration………… C 6 H 12 O 6 + 6O 2 > 6CO 2 + 6H 2 O + ATP Glucose + Oxygen > Carbon Dioxide + Water + Energy Glucose is oxidized to carbon dioxide (loses H atoms) and oxygen is reduced to water (accepts H atoms)

19. Salts – an ionic compound containing cations other than H + and anions other than the hydroxyl ion (OH - ). When salts are dissolved in water, they dissociate into their component ions. E.g., NaCl + water > Na + and Cl - . All ions are electrolytes, substances that conduct an electrical current in solution ACIDS and BASES Acids – a substance that releases hydrogen ions (H + ) and anions when dissolved in water; they are called proton donors; HCL H + Cl - ; H 2 CO 3 - HCO 3 - + H + Bases – a substance that releases hydroxyl ions (OH - ) and cations when dissolved in water; they are called proton acceptors; NaOH Na + + OH -
20. pH: Acid-Base Concentration The more H + ions in a solution, the more acidic the solution is. The more OH - ions, the more basic or alkaline the solution is. pH units measure the concentration of H + ions. The pH scale runs from 0 – 14 and is logarithmic, i.e., each successive change of one pH unit represents a tenfold change in H + concentration.
21. Buffers Homeostasis of acid-base balance is carefully regulated by the kidneys and lungs and by chemical systems called BUFFERS. Buffers help prevent large shifts of pH in the body fluids Strong Acids – acids that dissociate completely and irreversibly in water and they can change the pH of a solution. E.g., HCl; 100 HCl molecules + 1 ml water > 100 H+ and 100 Cl- Weak Acids – acids that do not completely dissociate. E.g., H 2 CO 3 ; 100 H 2 CO 3 + 1 ml water > 90 H 2 CO 3 + 10 H + + 10 HCO 3 Strong Bases – bases that dissociate easily in water and quickly tie up H + Weak Bases – bases that do not dissociate easily in water and accepts relatively few protons
32. Structural Levels of Proteins Primary – linear sequence of AA composing the polypeptide chain Secondary – twist or bend upon themselves to form a more complex structure ; alpha or beta Tertiary – 3d shape of a polypeptide chain; unique for each protein Quaternary – describes the arrangement of the individual polypeptide chains and how they bond
33.
34. Enzyme Action Active site Amino acids Enzyme (E) Enzyme-substrate complex (E-S) Internal rearrangements leading to catalysis Dipeptide product (P) Free enzyme (E) Substrates (S) Peptide bond H 2 O +
35. Protein Denaturation In hostile environments (temperature, pH) lose shape (secondary, tertiary and quaternary) When a protein is subjected to extremes (e.g., pH drops or temperature rises above normal) the protein will unfold and lose their specific 3d structure. The protein is said to have been DENATURED. In some cases, process is reversible. In extreme cases, the protein is said to have been irreversibly denatured. Example: egg (albumin is a protein that makes up the “white” of the egg)….uncooked the white is actually clear when you cook the egg (temperature rises above normal) the albumin is denatured (changes the color and the structural arrangement of the protein)
