A betel nut (also called betel quid) usually consists of three major ingredients: a raw areca nut, slaked lime, and Piper betle inflorescence. The size of a betel nut is usually about 3 cm × 3 cm × 2 cm (Figure 1). The acidity of a raw areca nut can cause stomach problems after repeated intake. With high alkalinity, the slaked lime can neutralize this acidity. Arecoline (the primary alkaloid in...

Abstract Korn is a software verifier that infers correctness certificates and violation witnesses sutomatically using state-of-the-art Horn-clause solvers, such as Z3 Eldarica. The solvers are used in portfolio together with cheap random sampling where the latter can be very effective at finding counterexamples. perfomend best sub-category of SV-COMP 2023.

BACKGROUND Peanuts and tree nuts frequently cause severe allergic reactions. Nut avoidance is the key treatment, and accurate identification of nuts is essential for successful avoidance. OBJECTIVES To determine the age at which nut-allergic and nonallergic children can accurately identify various nuts and whether nut-allergic children can identify nuts they should avoid. METHODS A "nut box...

To study how fire or herbicide use influences longleaf pine (Pinus palustris Mill.) overstory and understory vegetation, five treatments were initiated in a 5–6-year-old longleaf pine stand: check, biennial arborescent plant control by directed herbicide application, and biennial burning inMarch,May, or July. The herbicide or prescribed fire treatments were applied in 1999, 2001, 2003, and 2005...

This paper reports on an 8-year continuing project with the Sevilleta Long-Term Ecological Research program (LTER) in central New Mexico aimed at the study of dynamics of woodland ecosystems. The study of mast production was conducted at six experimental woodland sites situated across an elevational gradient of 1500–2000m in proximity to permanent meteorological stations. The dominant woody spe...

At the age of 3.5 years, wild chimpanzees at Bossou, Guinea, begin to use hammer and anvil stones to crack oil-palm nuts to get the kernels. To clarify the developmental processes, the authors did a field experiment in which stones and oil-palm nuts were provided. Infant chimpanzees' stone-nut manipulation was observed and video recorded. Data were collected from 3 infants younger than 4 years ...

We studied the effect of scion donor-tree age on the physiology and growth of 6- to 7-year-old grafted Scots pine (Pinus sylvestris L.) trees (4 and 5 years after grafting). Physiological measurements included photosynthethetic rate, stomatal conductance, transpiration, whole plant hydraulic conductance, needle nitrogen concentration and carbon isotope composition. Growth measurements included ...

Areca nut consumption has been implicated in the progression of Oral Submucous fibrosis (OSF); an inflammatory precancerous fibrotic condition. Our previous studies have demonstrated the activation of TGF-β signaling in epithelial cells by areca nut components and also propose a role for epithelial expressed TGF-β in the pathogenesis of OSF. Although the importance of epithelial cells in the ma...
