Laboratory safety rules are a major aspect of every clinical lab.
Each student in clinical laboratory must follow specific safety rules and procedures.
Laboratory safety
Your science laboratory must be a safe place to work and learn in. In doing any science activities, you must take responsibility for your own safety and the safety of others. The following guidelines will help you carry out science activities safely.
Personal Safety
1. Always obtain your teacher’s permission before performing any activity.
2. Always read and understand an activity thoroughly before doing it.
3. Always wear goggles when you see a corrosive symbol at the beginning of the activity.
4. Never run or play in the laboratory room.
5. If you have long hair, always tie it back before performing an experiment.
6. Always know where the following are kept: fire extinguisher, first aid kit, eyewash bath, and shower area. Know where the fire alarm and the nearest telephone are. Learn how to use them.
Safety in Handling Plants
1. Use caution when collecting or handling plants.
2. Do not eat or taste any unfamiliar plants or plant parts.
3. If you are allergic to pollen, do not work with plants or plant parts.
Safety in Handling Animals
1. Handle animals with care. If you are bitten or scratched by an animal, inform your teacher.
2. Do not bring wild animals in the classroom.
3. Do not cause pain, discomfort, or injury to an animal. Be sure that animals kept for observation are given the proper food, water, and living space.
4. Wear gloves when handling live animals. Always wash your hands with soap and water after handling them.
Eye Safety
1. Wear your laboratory safety goggles when you are working with chemicals, open flame, or any substances that may be harmful to your eyes.
2. If chemicals get into your eyes, flush them out with plenty of running water. Inform your teacher immediately.
Safety in Using Flammable and Hot Objects
1. Turn off heat sources when they are not in use.
2. Point test tubes away from yourself and others when heating substances in them
3. Use the proper procedure when lighting an alcohol lamp or Bunsen burner.
4. To avoid burns, do not handle heated glassware or materials directly. Use tongs, test tube holders, or heat-resistant gloves.
Glassware Safety
1. Check glasswares for chips or cracks. Broken, cracked, or chipped glassware should not be used. It should be given to the teacher for proper disposal.
2. Do not force the stopper into a glass tubing. Follow your teacher’s instructions.

DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
