Mulches bring several benefits to lettuce cultivation.A study on the lettuce ‘Red Rapids’ has been conducted to determine the influence of the different colored plastic mulch on its growth. The experiment consisted of five color treatments as follows; treatment 1- metallic silver (control), treatment 2- red, treatment 3- orange, treatment 4- yellow and treatment 5-green. Results showed that the...

Leaf colors of a plant can be used to identify stress level due to its adaptation to environmental change. For most leaves green-related colors are sourced from chlorophyll a and b. Chlorophyll concentration is normally measured using a spectrophotometer in laboratory. In some remote observation places, it is impossible to collect the leaves, preserve them, and bring them to laboratory to measu...

Palm leaves were one of the earliest forms of writing media and their use as writing material in South and Southeast Asia has been recorded from as early as the fifth century B.C. until as recently as the late 19th century. Palm leaf manuscripts relating to art and architecture, mathematics, astronomy, astrology, and medicine dating back several hundreds of years are still available for referen...

Let G = (V,A) be a vertex-colored arc-weighted directed acyclic graph (DAG) rooted in some vertex r. The color hierarchy graph H(G) of G is defined as follows: V (H(G)) is the color set C of G, and H(G) has an arc from c to c if G has an arc from a vertex of color c to a vertex of color c. We study the Maximum Colorful Arborescence (MCA) problem, which takes as input a DAG G such that H(G) is a...
