Acid Attack on Concrete

Acid Attack on Concrete

When acids come into contact with concrete, they initiate a chemical reaction that dissolves the hydrated cement paste. This process leads to softening and structural weakening of the concrete. This issue is commonly observed in environments such as chimneys, sewers, and industrial settings. The severity of the damage increases as the pH of the water interacting with the concrete drops below 6.5. In particular, a pH under 4.5 can cause significant concrete damage.
The rate at which hydrogen...

Sulfate Attack on Concrete

Sulfate Attack on Concrete

Sulfate attack on concrete is a deterioration process characterized by a whitish discoloration beginning at the edges and corners, accompanied by cracking and spalling. This phenomenon occurs when sulfates react with the components of hardened concrete, forming compounds like calcium sulfate and calcium sulfoaluminate which occupy more space than the substances they replace, causing the concrete to expand and disrupt.
Sulfates from sources like soil, groundwater, or industrial effluents...

Short-distance Transport of Resources

Short-distance Transport of Resources

Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Power System Three-Phase Short Circuits

Power System Three-Phase Short Circuits

Determining the subtransient fault current in a power system involves representing transformers by their leakage reactances, transmission lines by their equivalent series reactances, and synchronous machines as constant voltage sources behind their subtransient reactances. In this analysis, certain elements are excluded, such as winding resistances, series resistances, shunt admittances, delta-Y phase shifts, armature resistance, saturation, saliency, non-rotating impedance loads, and small...

Three-Phase Short Circuit—Unloaded Synchronous Machine

Three-Phase Short Circuit—Unloaded Synchronous Machine

Conducting a three-phase short circuit test on an unloaded synchronous machine helps understand its impact on the system. The AC fault current's oscillogram, with the DC offset removed, reveals that the waveform amplitude decreases from an initially high value to a steady-state level for one phase of the machine.
This behavior occurs due to the magnetic flux produced by the short-circuit armature currents. Initially, these currents follow high-reluctance paths but eventually shift to...

CRISPR and crRNAs

CRISPR and crRNAs

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

Summary

Short-lasting unilateral neuralgiform headache attacks (SUNHA), including SUNCT and SUNA, are rare but disabling. Emerging evidence suggests SUNHA, SUNCT, and SUNA may be part of a continuum with trigeminal neuralgia, potentially requiring reclassification.

Background:

Short-lasting unilateral neuralgiform headache attacks (SUNHA) encompass SUNCT and SUNA, characterized by unilateral trigeminal pain and autonomic features.
These conditions are rare, highly disabling, and pose management challenges due to short attack durations and limited abortive therapy effectiveness.

Purpose of the Study:

To review the management strategies for SUNHA, including pharmacological and surgical interventions.
To explore the potential nosological overlap between SUNHA (SUNCT/SUNA) and trigeminal neuralgia (TN).

Main Methods:

Review of pharmacological preventive treatments, including lamotrigine and lidocaine.
Analysis of surgical interventions such as trigeminal nerve ablation, microvascular decompression (MVD), and neurostimulation techniques.
Examination of clinical, therapeutic, and radiological similarities between SUNHA subtypes and TN.

Main Results:

Lamotrigine (oral) and lidocaine (intravenous) show promise as preventive and transitional treatments, respectively.
Surgical options including MVD, occipital nerve stimulation, and VTA deep brain stimulation have demonstrated effectiveness in open-label studies.
Significant overlap exists between SUNCT, SUNA, and TN, suggesting they may represent a spectrum of the same disorder.

Conclusions:

SUNHA management is challenging, with limited options for acute attacks but promising results from specific preventive medications and surgical interventions.
The findings support a broader nosological concept, potentially classifying SUNHA with trigeminal neuralgia as a cranial neuralgia rather than a distinct entity.
