Total (absolute) Porosity and Isolated Porosity MeasurementRaboon Redar
Absolute porosity is the percentage or volume of void spaces or porosity of rocks that can contain hydrocarbons. Porosity is the measure of a rock’s ability to hold hydrocarbons like oil and gas, water, and condensates. Absolute porosity contains effective (interconnected) and ineffective (isolated) porosity. Effective porosity is the volume of connected pores, but isolate is the pore volume which is not connected to the pore network. Isolated porosity can be significant in volcanic rocks and some carbonates.
Porosity is the quality of being porous, or full of tiny holes. Liquids go right through things that have porosity. It is shown as a fraction of the volume of voids over the total volume, which is between 0 and 1, or between 0% and 100% as a percentage. Primary and secondary porosity can be read directly from neutron, density, and sonic logs.
Determining an unknown Density of a RockRaboon Redar
The main aim of this experiment is to find out the density of a rock using two basic ways. Density is defined as the mass of a substance per unit volume, and is highly variable in crustal rocks. Rock density is a physical characteristic that is governed by the chemical composition and pore spaces of a specific rock or rock type. Rock densities are useful to engineers, of course. They're also essential for geophysicists who must model the rocks of the Earth's crust for calculations of local gravity. In most cases, denser objects are also heavier.
Electricity and Electromagnetism (experimental study)Raboon Redar
You’ll understand the way to calculate and measure resistance in parallel and series circuits by knowing two of the three values of voltage, current, or resistance. In this experiment, there are 3 resistors, 1 power supply and wires you need for connecting resistors to each other, then to power supply. You can measure each resistor by an ohmmeter, voltages by voltmeter and currents by amperemeter (ammeter), while all of them can be measured by a multimeter. Use a multimeter for measuring resistance for better accuracy.
Physical Properties of different types of Metamorphic Rocks (Geology)Raboon Redar
Metamorphic rocks are rocks that have been modified by heat, pressure, and chemical processes, usually while buried deep below Earth's surface. Change to these extreme conditions changes the mineralogy, texture, and chemical composition of the rocks.
A rock is lustrous and shiny if it has Dolomite Crystall which is lustrous in front of the sun. Formation are some kinds of rocks which can be seperated due to some general principles like age, lithology and fossils, and when you separate them, you give them a name like: Sargalu, Surdash, Nawkalakan, Berserin, Bexma...etc
Physical Properties of different types of Sedimentary Rocks (Geology)Raboon Redar
The rock type, texture, grain size, composition, and other comments on the sedimentary rocks is shown...
Sediment is a material that is occurred naturally and broken down by processes of physical or chemical weathering, and erosion. Physical weathering like: Frost wedging, Unloading, Thermal Expansion and Biological activity. Chemical weathering like: Dissolution, Hydrolysis and Oxidation.
Weathering rates are a function of the rock type, slope (topography), structure, and the prevailing climate. Rocks that are most resistant are composed of minerals that are relatively unaffected by chemical weathering like: Quartz (that are more resistant than any other rock types). Sediments are transported by the action of wind, ice (glaciers), the gravity force acting on particles and most of them by water. Sediments can be classified based on their composition and grain size which is a good indicator of the energy or force required to move a grain of a given size.
Physical Properties of different types of Igneous Rocks (Geology)Raboon Redar
the texture, color, mineral composition, intrusive or extrusive, equivalent, felsic or mafic of the igneous rocks are discussed... (from the Greek word for fire) form from when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.
Physical Properties of different types of Minerals (Geology)Raboon Redar
This report shows the luster, hardness, color, cleavage, streak, fracture, crystal system, chemical composition, and remarks of different types of minerals...
Geologists define mineral as any naturally occurring inorganic solid that has an orderly crystalline structure and can be represented by a chemical formula. A compound needs to exhibit these 5 characteristics to be called a mineral: naturally occurring, has to be solid substance, orderly crystallized structure, generally inorganic (not contain carbon), and should be represented by a chemical formula.
Chemical and Physical Properties of Earth's Layers and the Tectonic Plates (G...Raboon Redar
To determine the chemical composition inside the Earth indirect measurements are used. One way to determine composition is to measure how the density of rock changes with depth below the Earth’s surface. We can do this by measuring the speeds, because they move more quickly through dense rocks than through less dense rocks. From such measurements we know that density increases with depth, but not evenly. Knowing these different densities, we can estimate what the composition of the different layers must be. The layers of different chemical composition outward from the centre of the Earth are as follows: core, mantle, and crust.

Dead – Weight piston gauge & Center of PressureRaboon Redar
The calibration of the Bourdon gauge is the aim of the dead weight pressure gauge experiment, while the center of pressure is the other test’s aim to find the resultant force (F) and center of pressure (hp). For testing and changing pressure gages, the death-weight pressures gage is used. The pressure is exerted by weights which are supported by weight. The latter has a piston that operates on hydraulic oil in the pipe system to show those pressures by a pressure gage that is also attached to the system. A Bourdon gage with a clear dial is included in the device. Thus, there is a simple identification of the display mechanism and the different adaptation choices.
The aim of the fluid flow rate experiment is to measure the fluid flow rate using a device called the hydraulic bench unit, which is also used to prove the Bernoulli’s Theorem Demonstration by measuring the overall pressure of the fluid flow.
Liquid–liquid extraction (LLE) also known as solvent extraction is a method to separate compounds based on their relative solubility in two different immiscible liquids, usually water and an organic solvent. Liquid–liquid extraction is a separation process which is based on the different distribution of the components to be separated between two liquid phases.
Applications of Differential Equations in Petroleum EngineeringRaboon Redar
In modern science and engineering, differential equations are very important. Nearly all known physics and chemistry laws are indeed differential equations. Engineers, in order to investigate systems behavior, it is virtually necessary that they are able to model and solve physical problems with mathematical equations.
Geophysical methods in Hydrocarbon ExplorationRaboon Redar
Geophysical studies of the earth's interior include measurements on or near to the earth's surface that are dependent upon the physical properties of the internal distribution. Examination of these measurements can show how vertically and laterally the physical properties of the Earth's interior differ. Through operating on different scales, geophysical techniques can be used to investigate the localized upper crust area for engineering or other purposes.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
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.

Title: Standardization of 0.1N (NaOH) by Standardized (HCl)
Experiment Number: 5
Name: Raboon Redar Mohammed
Group: A
Date: 28/04/2019
Supervisor(s): Dr. Hemn Abdulqadr
Ms. Fenk Abdulrazaq
2. Aim:
The aim of this experiment is to standardize 0.1N Sodium Hydroxide (NaOH) which is
an unstandard substance, by using standardized Hydrochloric acid (Na2CO3).
Introduction:
At the first step, an amount of (NaOH) which also contains Co3 is needed to dissolve
it into 250ml of distilled water to get a "0.1N NaOH solution". Same thing at the
other hand, you need to find N1, and then by the N1V1 = N2V2 theory, you get the
amount of concentrated HCl in (ml) that is needed to obtain "0.1N HCl in 250ml of
distilled water" into a Conical Flask. Dilute 10ml of the 0.1N NaOH into a conical flask
and drop 2 - 3 drops of methyl red using a pipette until its color becomes yellow. Fill
a 250ml burette by the 0.1N HCl and slowly start opening the valve to drop the HCl
into the 10ml 0.1N NaOH conical flask until its color changes to red then close the
valve and stop dropping. Measure the HCl volume remaining in the graduated
cylinder to use it in the N1V1 (HCl) = N2V2 (NaOH) and calculate the N2 of the NaOH.
Materials:
1. Electronic Balance
2. Scoopula
3. Beaker
4. Conical Flask
5. Pipette
6. Methyl Red
7. Burette with Valve
8. Hot Plate
Procedure:
By knowing the Normality (0.1N), Volume (250ml) and equivalent weight (53)...
calculated, 0.95g of NaOH weight is needed to dissolve into a 250ml distilled water to
3. obtain "0.1N NaOH solution". NaOH grains are big, so a hot plain may be needed to
dissolve NaOH in water. By knowing the average, specific gravity, Normality of the
HCl before dilution is calculated which is equal to 12eq/L and then by equaling the
no. of milliequivalence before dilution with the no. of milliequivalence after dilution,
Volume of HCl before dilution is calculated which is equal to 2ml. Now take 2ml of
concentrated HCl with a pipette and dilute it to 250ml with distilled water in a 250ml
Pipette to obtain approximately 0.1N HCl. Drop 10ml of NaOH into a conical flask,
drop 2 - 3 drops of methyl red into conical flask to change its color to yellow. Start
opening the valve to drop the HCl into the 10ml 0.1N NaOH conical flask until its
color changes to red then close the valve and stop dropping. Measure the remaining
HCl volume in the pipette (6ml).

Discussion:
One thing to focus on is whenever you see the yellow color changes to red,
immediately close the valve. When it's said yellow to red, you may think that the
color isn't yellow enough and do not close the valve, but actually at the drop the
yellow color changes to red is enough.
Result:
As a result, after the procedure is done on the conical flask, 0.1N standardized NaOH
is obtained.
