Masonry Curtain Walls01:20

Masonry Curtain Walls

Masonry curtain walls employ brick or stone veneers supported by the building's structure to form an external cladding system that is both aesthetically appealing and functional. These walls are erected through two principal techniques, first by traditional layering of masonry units and second by using prefabricated panels. Traditional construction relies on steel shelf angles attached to the spandrel beam for support, with high-bond mortars ensuring secure attachment of masonry veneer units.
Current Dividers01:10

Current Dividers

In parallel electrical connections, resistors are linked between the same pair of nodes, creating an equal voltage across each resistor. Kirchhoff's current law is applied to these connections, establishing that the sum of currents through these resistors equals the source current. Utilizing Ohm's law, the source current is determined as the product of the source voltage and the sum of the reciprocals of individual resistances. This relationship simplifies the process of finding the current...
Heating and Cooling Curves02:44

Heating and Cooling Curves

When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...
Sleep-Wake Cycles01:24

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and  rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:
Spanning Openings in Brick Walls01:20

Spanning Openings in Brick Walls

In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...
Setting Time of Cement01:12

Setting Time of Cement

The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

Area of Science:

  • Neuroscience
  • Infectious Diseases
  • Ophthalmology

Background:

  • Cryptococcal meningitis is a serious fungal infection primarily affecting immunocompromised individuals.
  • Cranial nerve palsies are known complications, but isolated bilateral cranial nerve III dysfunction is rare.

Observation:

  • A 55-year-old immunocompetent male presented with headache, nausea, and progressive bilateral ptosis and diplopia.
  • Ophthalmological examination revealed bilateral asymmetric ptosis and restricted eye movements (adduction and elevation).

Findings:

  • Cranial MRI demonstrated enhancing intra-axial and extra-axial lesions in the midbrain.
  • Cerebrospinal fluid analysis confirmed Cryptococcus neoformans infection via positive antigen and fungal cultures.
  • The patient received liposomal amphotericin B and flucytosine for treatment.

Implications:

  • This case highlights that cryptococcal meningitis, even in immunocompetent hosts, can manifest with isolated bilateral cranial nerve III palsies.
  • Early diagnosis and appropriate antifungal therapy are crucial for favorable neurological outcomes.
  • Clinicians should consider cryptococcal meningitis in the differential diagnosis of unexplained bilateral cranial nerve III dysfunction.
