In Situ Tests: Parameters, Methods, Limitations

In situ tests: Values of different parameters are obtained from theoretical interpretation of the test result. Compared with laboratory tests, in situ tests reduce some limitations such as:

• Disturbance of soil samples (matters less; no transport of the sample).
• Change in the stress state of the sample.
• Small size of laboratory samples may be unrepresentative (a larger portion of the soil is involved).

Other limitations appear:

• Some disturbance is always present.
• Less control over test conditions (in the laboratory we can control water conditions).
• If the parameters of the theoretical model are two or more, only a relationship between them is obtained (for example, E and ν, or c and φ).

Understanding Soil Exploration: Test Pits & Boreholes

Test Pits and Trial Pits

Test pits, also known as trial pits, are excavations made in the soil to observe and analyze the subsurface layers. These pits are typically dug to a depth of less than 5 meters and have a width of no more than 0.75 to 1 meter. Key requirements for test pit excavation include:

• Wall stability to ensure safety and accurate observation.
• Excavation above the Groundwater Level (GWL) where possible.
• Soil excavation primarily by mechanical means.

Test pits are utilized to explore soil conditions and the sequence of strata up to a depth of 4-5 meters. They also allow for the collection of soil samples for subsequent laboratory testing.

Chapter 3: Statelessness

This means that each request from a service consumer should contain all the necessary information for the service to understand the meaning of the request. All session state data should then be returned to the service consumer at the end of each request.

Figure 5.2. Statelessness ensures that each service consumer request can be treated independently by the service.

Chapter 1 Introduction to Services

3.1. Service Terminology Service

a service is a software program that makes its functionality available via a technical interface, called a service contract.

Figure 3.1. The symbol used to represent an abstract service.

Service Contract

The symbol used to represent a service contract is displayed in Figure 3.2.

Service Capability

A service contract can be broken down into a set of service capabilities, each of which expresses a function offered by the service to other software programs.

Figure 3.4. A Purchase Order service contract with four service capabilities.

Service Consumer

A service consumer is software program when it accesses and invokes a service—or, when it sends a message to a service capability

Introduction to Geology Fundamentals

The Development of Geological Thought

The understanding of Earth's history evolved through competing theories:

• Mid-1600s – James Ussher: Catastrophism
  • Proposed that Earth’s landscapes were shaped primarily by sudden, short-lived catastrophes.
• 1795 – James Hutton: Uniformitarianism
  • States that the physical, chemical, and biological laws that operate today have operated throughout the geologic past.
  • Famous maxim: “The present is the key to the past.”

Energy Sources of the Earth System

The Earth system is powered by two main sources:

External Processes (Solar Energy)

The Sun drives external processes occurring in the:

• Atmosphere
• Hydrosphere
• At Earth’s surface

Internal Processes (Earth's Interior Heat)

The Earth... Continue reading "Fundamentals of Physical Geology: Structure, Systems, and Rock Cycle" »

If this story had been told differently, it wouldn't have mattered to anyone. The best thing about this film is the narrative. It has such an attractive and comical principle that it catches anyone. Showing the characters with insignificant details brings them closer to the ordinary mortal, so full of obsessions or supposed oddities. They and not the protagonist of the story are, in my opinion, the success of this film. Amelie is a normal character who becomes the centerpiece of a story because of her kindness. Here she appears as a modern fairy godmother, even if she replaces the magic wand with toothpaste, slippers or intentional phrases. That's why the first part of the film, where the different human stories appear, is the one I liked the... Continue reading "Amelie: A Modern Fairy Godmother and the Power of Narrative" »
