Total Voids in Concrete

Total Voids in Concrete

Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

Conditions on Early Earth

Conditions on Early Earth

Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and hydrogen into the primordial atmosphere. However, organisms with the characteristics of life were not initially present on earth. Scientists have used experimentation to determine how organisms evolved that could grow, reproduce, and maintain an internal environment.

Classical Conditioning

Classical Conditioning

Associative learning, a core principle in behavioral psychology, involves forming connections between events and facilitating learned responses. This concept is vividly illustrated by classical conditioning, a process extensively studied by the Russian physiologist Ivan Pavlov. Pavlov's pioneering research on dogs' digestive systems led to the discovery that behaviors can be learned through association, laying the groundwork for classical conditioning.
Ivan Pavlov observed that dogs...

Total Internal Reflection Fluorescence Microscopy

Total Internal Reflection Fluorescence Microscopy

Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Conditions of Equilibrium

Conditions of Equilibrium

Equilibrium refers to a state where a rigid body is not subjected to any translational or rotational motion. This state is achieved when the force and couple acting on a rigid body equal zero. When the system of external forces results in a net effect equivalent to zero, the rigid body is considered to be in equilibrium.
Internal forces are not considered for conditions of equilibrium because they occur in equal and opposite pairs within the body, effectively canceling each other. As a result,...

Operant Conditioning

Operant Conditioning

Operant conditioning, a key concept in behavioral psychology, involves using reinforcement and punishment to alter the likelihood of a behavior being repeated. B.F. introduced this type of conditioning. Skinner focused on voluntary behaviors and the consequences that follow them, influencing whether these behaviors will be strengthened or diminished.
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...

Summary

Total hip arthroplasty for posttraumatic arthritis presents unique surgical challenges and risks. Outcomes are generally less favorable than for primary osteoarthritis, with higher complication rates.

Area of Science:

Orthopedics
Rheumatology
Trauma Surgery

Background:

Posttraumatic arthritis is a significant cause of secondary hip osteoarthritis.
Total hip arthroplasty (THA) for posttraumatic arthritis involves greater technical difficulty than for primary or inflammatory arthritis.
Challenges include bone deformities and the presence of prior hardware.

Purpose of the Study:

To highlight the complexities and outcomes of THA in posttraumatic arthritis.
To emphasize the necessity of thorough preoperative planning for bone deficiencies and hardware removal.
To compare THA results in posttraumatic arthritis with those in primary osteoarthritis.

Main Methods:

Review of surgical considerations for THA in posttraumatic arthritis.
Analysis of preoperative evaluation requirements.
Comparison of outcomes and complication rates.

Main Results:

THA for posttraumatic arthritis is technically demanding due to bone deformities and retained implants.
Preoperative planning is crucial for approach, hardware removal, and implant selection.
Results show a higher incidence of complications (fractures, infection, instability) and lower survivorship compared to primary osteoarthritis THA.

Conclusions:

While THA is successful for posttraumatic arthritis, outcomes are less favorable than for primary osteoarthritis.
Increased intraoperative and postoperative complications are associated with posttraumatic arthritis THA.
Careful preoperative assessment and surgical strategy are essential for managing bone deficiencies and improving outcomes.
