The presentation discusses the role of flavonoids in biological nitrogen fixation (BNF). Flavonoids are polyphenolic plant compounds found in fruits and vegetables that function as antioxidants and regulate auxin transport, UV protection, and defense against pathogens. Specifically, flavonoids in the rhizosphere interact with microorganisms and play a role in symbiosis. Manipulating the flavonoid pathway could improve root-rhizosphere interactions and BNF, but their multiple functions require caution when attempting to alter rhizosphere signals.

It then describes maceration as soaking crushed plant material in a solvent for a period of time to soften cells and dissolve soluble constituents. The key steps of maceration involve adding crushed plant material and solvent to a vessel, soaking for 7 days, straining and pressing the plant material, and filtering and concentrating the extracted liquid. Larger scale extraction processes like circulatory extraction and multiple stage extraction in an extraction battery are also summarized to improve efficiency.Glycosides

How Psychology Can Power Product Decisions: A Human-Centered Blueprint- Shray...ShrayasiRoy2
油
In an era where users are bombarded with endless choices, capturing attention and driving meaningful engagement isn't just about building features it's about understanding what drives human behavior at its core. This presentation offers a deep dive into how psychological principles can inform smarter, more intuitive product decisions. Its not just theory its a hands-on blueprint for applying human-centered thinking at every stage of product development.
Grounded in behavioral science, consumer psychology, and cognitive design, this deck unpacks the key psychological drivers behind user motivation, decision-making, emotional engagement, and habit formation. From attention economics and dopamine-driven interactions to trust cues, loss aversion, and the paradox of choice you'll see how to harness what the mind naturally does to build digital products people dont just use they return to, talk about, and even advocate for.
Well explore:
Cognitive biases that shape user perception and choices and how to use them to your advantage without crossing ethical lines.
Emotional design principles that build trust, trigger desire, and turn features into feelings.
User behavior loops that build stickiness, deepen retention, and create emotional investments.
Psychological friction when to reduce it for conversion, and when to add it for intentionality.
Dark patterns vs. ethical persuasion the thin line between influence and manipulation.
A/B testing with a psychological lens learning not just what works, but why it works.
This is more than UX research or product marketing fluff. Its a call to build with empathy, backed by science, and sharpened by real-world product thinking. Whether youre shaping onboarding flows, gamifying engagement, designing pricing models, or rethinking retention strategies this deck will arm you with a new lens: the human mind.
Perfect for product managers, growth strategists, UX designers, behavioral scientists, and anyone serious about building products that resonate, retain, and inspire action.
Because at the heart of every great product is a human.

Thiazole derivatives of N-substituted isatin have attracted significant interest due to their wide-ranging applications in medicinal chemistry, pharmaceuticals, and materials science. These compounds exhibit diverse biological activities, making them promising drug candidates, while their unique chemical structures offer potential in designing advanced functional materials. This presentation focuses on the synthesis and characterization of these derivatives through targeted chemical reactions involving various substituents on the isatin and thiazole cores, enabling the fine-tuning of their biological and physical properties. Characterization techniques such as NMR, FT-IR, Mass Spectrometry, and X-ray crystallography are employed to confirm molecular structures and analyze solid-state properties. These methods provide critical insights into the structureactivity relationships of the synthesized compounds. Our presentation highlights the synthetic pathways, structural elucidation, and potential applications of thiazole-based N-substituted isatin derivatives, aiming to support ongoing advancements in drug discovery and material development.

Flavonoids
- 3. Presentation Topic: Role of flavonoids in BNF Presented To: Dr. Ijaz Ahmad Randhawa Presented By:Aown Abbas Roll No.46 Class B.Sc(HONS.)Agriculture 2013-17 College of Agriculture BZU Bahadur Sub-Campus LAYYAH
- 4. Flavonoids are a group of plant metabolites thought to provide health benefits through cell signalling pathways and antioxidant effects. These molecules are found in a variety of fruits and vegetables. Flavonoids are polyphenolic molecules containing 15 carbon atoms and are soluble in water. What are flavonoids ?
- 5. Role of Flavonoids in BNF The flavonoid pathway produces a diverse array of plant compounds with functions in UV protection, as antioxidants, pigments, auxin transport regulators, defence compounds against pathogens and during signalling in symbiosis.
- 6. This review highlights some of the known function of flavonoids in the rhizosphere, in particular for the interaction of roots with microorganisms.
- 7. Therefore, the manipulation of the flavonoid pathway to synthesize specifically certain products has been suggested as an avenue to improve rootrhizosphere interactions. Possible strategies to alter flavonoid exudation to the rhizosphere are discussed.
- 8. In addition, the overlapping functions of many flavonoids as stimulators of functions in one organism and inhibitors of another suggests caution in attempts to manipulate flavonoid rhizosphere signals.
