helium porosimeter (Reservoir lab)
This document describes an experiment conducted using a helium porosimeter to determine the effective porosity of a core sample. The experiment followed standard procedures, including loading the sample into a matrix, setting the reference pressure, and measuring the sample volume and weight. The effective porosity was calculated based on Boyle's law and found to be -4.68%. Potential sources of error are discussed, such as temperature fluctuations affecting gas volume and ensuring pressure stabilization between valve changes. The document provides background on helium porosimetry and its use of gas expansion principles to determine porosity.
Porosity by saturation method
This experiment aims to determine the porosity of a core sample using the saturation method. The procedure involves saturating a dry core sample with brine under vacuum and pressure, then measuring the saturated and dry weights to calculate pore volume and porosity. Effective porosity is measured, representing the interconnected pores that contain movable fluids like brine. Core plugs are analyzed to determine physical rock properties like porosity and permeability important for calculating oil and gas in place volumes. The result of porosity value for the sample will be reported to the nearest 0.1%.
Reservoir Geomechanics
The document discusses compaction and subsidence that can occur during oil and gas production due to a reduction in pore pressure. It describes how effective stress increases as pore pressure declines, causing the reservoir rock to compact. This compaction at the reservoir level can result in subsidence at the surface. Key factors that influence compaction and subsidence are identified as reservoir rock properties, thickness, pore pressure depletion, and areal extent. The ratio between subsurface compaction and surface subsidence is also addressed.
Core cleaning
This experiment aims to clean a core sample using the Soxhlet extraction method to remove any oil or water and preserve the original properties of the reservoir rock. The core sample is placed in a thimble and submerged in toluene solvent inside a Soxhlet apparatus. Toluene is slowly boiled and condenses, flowing over the core sample and removing any contaminants through multiple cycles. After drying, the core sample weight is measured before and after to calculate fluid saturations and determine if the cleaning was successful in purifying the core.

Anesthesia workstation
The key points of the document are:
1) The most important part of pre-use checks on an anesthesia workstation is verifying the presence of a self-inflating resuscitation bag in case of issues with ventilation or oxygenation.
2) An ideal vaporizer would maintain a constant output concentration regardless of changes in gas flow, temperature, pressure, or carrier gas composition, but real vaporizers are affected by these factors.
3) Modern vaporizers use various techniques like temperature compensation and automatic controls to minimize fluctuations in vapor concentration due to changes in ambient conditions.
Particle size analysis hydrometer
Particle size analysis can be done through sedimentation analysis or hydrometer analysis. Sedimentation analysis uses Stokes' law to determine grain size distribution of soil fractions smaller than 75 micrometers based on how quickly different sized spherical particles settle through a liquid. Hydrometer analysis indirectly calculates grain size distribution of fine particles less than 0.05 mm by measuring the density of a soil suspension with a hydrometer at different time intervals, as finer particles settle more slowly over time according to their diameter. A calibration plot is made to account for the hydrometer's immersion effect on readings.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
