Social Foundations of Self IV: Self in Digital Communication

Social Foundations of Self IV: Self in Digital Communication

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Uncertainty in Measurement: Reading Instruments

Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Uncertainty in Measurement: Significant Figures

Uncertainty in Measurement: Significant Figures

All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.

Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Specific Heat

Specific Heat

The specific heat capacity of a substance refers to the energy required to increase the temperature of one gram of that substance by one degree Celcius. Specific heat capacity is often represented in calories (cal), grams (g), and degrees Celsius (oC), but can also be expressed in joules (J), kilograms (kg), and Kelvin (K), among other units.
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or...

Electron Affinity

Electron Affinity

The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).

Area of Science:

Oral and Maxillofacial Prosthodontics
Biomaterials Science

Background:

Hand deformities impact daily function and appearance.
Rehabilitation options include microsurgery and silicone prostheses.
Oral and maxillofacial prosthodontists play a role in fabricating prosthetic replacements.

Observation:

A nonsurgical approach was used for first digit rehabilitation.
Customized silicone prosthesis was fabricated for a patient with an amputated thumb.
Vacuum-retained silicone prosthesis is a viable alternative to mini-implant-retained prostheses.

Findings:

Fabrication of an esthetically pleasing and functional silicone thumb prosthesis is achievable.
The vacuum-retained method provides a minimally invasive retention solution.
This technique addresses both functional and esthetic deficits following thumb amputation.

Implications:

Silicone prostheses offer significant psychological, functional, and esthetic benefits for patients with hand deformities.
Advancements in materials and techniques enhance the quality of prosthetic rehabilitation.
Minimally invasive techniques like vacuum retention improve patient accessibility and outcomes.
