dryopteris expansa (c.pres l.) fraser- jenkins & jermy is reported at the first time for fern flora of iranfrom pice-son forests, asalem to khalkhal road in the hyrcanian phytogeographia region. it's most distinctivemorphological character is the presence of rachis, white petiole, three pinnate lamina, rectangular pinnules,scales with darker band in the middle part. dryopteris expansa is s...

Discrete-time discrete-state finite Markov chains are versatile mathematical models for a wide range of real-life stochastic processes. One most common tasks in studies is computation the stationary distribution. Without loss generality, and drawing our motivation from applications to large networks, we interpret this problem as one computing distribution random walk on graph. We propose new co...

Monochromatic green light-emitting diodes (LED) light stimuli influences the posthatch growth performance of chicks. This study was undertaken with the following objectives: i) to examine whether the green LED light stimuli induces an overheating effect by determining weight loss rate of fertile eggs during incubation period; ii) to look for the development of eyes and other primary organs at d...

The watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai var. lanatus) has high variability for fruit size, shape, rind pattern, and flesh color. This study was designed to measure the qualitative inheritance of rind phenotypes (solid dark green vs. light green). For each of the 2 families, "Mountain Hoosier" × "Minilee" and "Early Arizona" × "Minilee," 6 generations (P(a)S(1), P(b)S(1), F(1)...
