A CT Scan typically combines various rotating X-Rays along with hi-end computerised processing to initiate a more detailed ‘picture’ of the inner structures of a body – including bones, tissues, and organs. A CT Scan is generally done on a patient's spine, heart, head, chest, abdomen, face, and knee. During a CT Scan, the body is made to pass by a tunnel-like machine that rotates through a 360-degree arc as it takes pictures in rapid succession. These images are eventually fed into a computer to produce an ‘all-around’ 2D snap of any part of the body. While the process of CT scan starts the contrast (substance) is taken by mouth or through an injection to see all the organs more clearly.

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.
ANAMOLOUS SECONDARY GROWTH IN DICOT ROOTS.pptxRASHMI M G
Abnormal or anomalous secondary growth in plants. It defines secondary growth as an increase in plant girth due to vascular cambium or cork cambium. Anomalous secondary growth does not follow the normal pattern of a single vascular cambium producing xylem internally and phloem externally.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
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.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
2. types of lung imaging to detect lung cancer
include:
• Chest x-ray. A chest x-ray is often the first test your doctor
will do to look for any abnormal areas in the lungs. ...
• Computed tomography (CT) scan. ...
• Magnetic resonance imaging (MRI) scan. ...
• Positron emission tomography (PET) scan. ...
3. CHEST X-RAY OF LUNG CANCER
An X-ray, or, much less commonly, X-radiation, is a penetrating form of
high-energy electromagnetic radiation. Most X-rays have
a wavelength ranging from 10 picometers to 10 nanometers
A chest X-ray is usually the 1st test used to diagnose lung cancer. Most
lung tumour appear on X-rays as a white-grey mass.
However, chest X-rays cannot give a definitive diagnosis because they
often cannot distinguish between cancer and other conditions, such as a
lung abscess (a collection of pus that forms in the lungs).
4.
5. CT SCAN OF LUNG CANCER
A CT scan uses x-rays to make detailed cross-sectional images of
your body. Instead of taking 1 or 2 pictures, like a regular x-ray, a
CT scanner takes many pictures and a computer then combines
them to show a slice of the part of your body being studied.
A CT scan is more likely to show lung tumors than routine chest x-
rays. It can also show the size, shape, and position of any lung
tumors and can help find enlarged lymph nodes that might
contain cancer that has spread.
This test can also be used to look for masses in the adrenal glands,
liver, brain, and other organs that might be due to the lung cancer
spread.

8. MRI OF LUNG CANCER
An MRI also produces images that allow doctors to see the location of a lung
tumor and/or lung cancer metastases and measure the tumor’s size.
An MRI uses magnetic fields, not x-rays, to produce detailed images of the body.
A special dye called a contrast medium is given before the scan to create a
clearer picture.
This dye can be injected into a patient’s vein or given as a pill or liquid to swallow.
However, MRI scanning does not work well to take pictures of parts of the body
that are moving, like your lungs, which move with each breath you take.
For that reason, MRI is rarely used to look at the lungs. It may be helpful to find
lung cancer that has spread to the brain or bones.
9.
10. PET SCAN OF LUNG CANCER
A PET scan is usually combined with a CT scan called a PET-CT scan.
A PET scan is a way to create pictures of organs and tissues inside the body.
A small amount of a radioactive sugar substance is injected into the patient’s
body.
This sugar substance is taken up by cells that use the most energy.
Because cancer tends to use energy actively, it absorbs more of the
radioactive substance.
A scanner then detects this substance to produce images of the inside of the
body.
