Outlandish manifestation of swelling in early childhood seen in the patient's floor of the mouth.

Ranula is a cyst-like growth that occurs in the oral cavity beneath the tongue. It consists of saliva from a ruptured salivary gland or duct. Rather than just flowing directly from the glands into the oral cavity, saliva permeates the nearby connective tissues and creates a bubble.

Relations between ordinary energy and energy of a self-loop graph.

Let be a graph on vertices with vertex set and let with . Denote by , the graph obtained from by adding a self-loop at each of the vertices in . In this note, we first give an upper bound and a lower bound for the energy of () in terms of ordinary energy (), order () and number of self-loops ().

Improved access to polythioesters by heterobimetallic aluminium catalysis.

Bimetallic Al(III) catalysis mediates thioanhydride/epoxide copolymerisation at greatly improved rates and monomer tolerance than analogous Cr(III) catalysis. Moving to sulfurated monomers furthermore generally improves rates and selectivites.

Comparison of salivary flow rate and pH between healthy subjects and tobacco and areca nut chewers.

Introduction: Tobacco and areca nuts release carcinogens, which cause alterations in saliva. Evaluation of these changes through estimation of salivary flow rate and pH was performed in tobacco and areca nut chewers and apparently healthy subjects.

Material And Methods: The study group for this comparative study comprised 60 subjects with 20 areca nut chewers (group 1), 20 tobacco chewers (group 2), and 20 non-tobacco and areca nut chewers (group 3) in the ages between 18 and 75 years.

Land Use and Land Cover Change Detection Using the Random Forest Approach: The Case of The Upper Blue Nile River Basin, Ethiopia.

Monitoring land use change dynamics is critical for tackling food security, climate change, and biodiversity loss on a global scale. This study is designed to classify land use and land cover in the upper Blue Nile River Basin (BNRB) using a random forest (RF) algorithm. The Landsat images for Landsat 45, Landsat 7, and Landsat 8 are used for classification purposes.
