Spectrophotometer instrumentation & working Sabahat Ali
Spectrophotometric analysis is a technique to measure the concentration of solute solution by measuring the amount of light absorbed by solution.
Absorption can be calculated in terms of transmittance by using Beer's Lambert law.
http://www.redicals.com
The spectrophotometer technique is to measures light intensity as a function of wavelength.
• Measures the light that passes through a liquid sample
• Spectrophotometer gives readings in Percent Transmittance (%T) and in Absorbance (A)
UV-Visible spectroscopy is considered as an important tool in the analytical chemistry.
Most powerful tool available for the study of atomic and molecular structure.
- Most commonly used techniques in clinical as well as chemical laboratories.
- Used for the qualitative analysis and identification of chemicals.
ain use is for quantitative determination of different organic and inorganic compounds in solution.
Basically, spectroscopy is related to the interaction of light with matter.
As light is absorbed by matter, the result is an increase in the energy content of the atoms or molecules.
The absorption of visible or ultraviolet light by a chemical compound will produce a distinct spectrum.
UV-Visible light range- 200-800 nm
Visible range: 400-800 nm
UV range: 200-400 nm
Spectroscopy is the study of the interaction of electromagnetic radiation in all its forms with the matter. The interaction might give rise to electronic excitations, (e.g. UV), molecular vibrations (e.g. IR) or nuclear spin orientations (e.g. NMR). Thus Spectroscopy is the science of the interaction of energy, in the form of electromagnetic radiation (EMR), acoustic waves, or particle beams, with the matter.
Here in this article, the matter is studied in further detail.
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.
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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

11. Single-beam spectrophotometer The light source (1) is a tungsten lamp. Its polychromatic light passes through a condensor (2) and reflects from a mirror (3) to the input slit (4) of the monochromator (parts 4 to 8, plus 12). The light is collimated (5) onto a reflection optical grating (6) which forms a colour spectrum. An almost monochromatic light is projected by an objective (7) onto the exit slit (8) of the monochromator.
12. The grating is rotated by means of a wavelength selection control (12) to choose wavelength directed into the exit slit. The light beam passes through a cuvette (9) with the sample. Intensity of the transmitted light is measured by a photodetector (10, 11). Signal from the detector is amplified by an amplifier (13). The value of absorbance is displayed (14). Intensity of the light transmitted through the reference solution is always compared with the intensity of the same beam passed through the measured sample. Single-beam spectrophotometer

37. Patch-clamp Method Some ion channels may be closed or opened in advance, the microelectrode filling may even contain ligands capable of interaction with ion channels, and in general any substances that can affect the function of the membrane. This discovery enabled to examine the activity of the individual or small groups of ion channels. A blunt glass microelectrode clings to the surface of the cell or an isolated part of the biological or artificial membrane. The opening at the end of the microelectrode is completely sealed by the membrane “patch” and the measured electric voltages or currents thus relate to only a small part of the membrane, in which a small number of ion channels are found.
