Splenectomy or pretreatment of adult hamsters with cyclophosphamide (Cytoxan) increased the lethality of the TC-83 vaccine strain of Venezuelan encephalitis virus (VEE), inoculated subcutaneously, from 12% for normal hamsters to 75 and 76%, respectively. Neither splenectomy nor cyclophosphamide treatment significantly increased the lethality of Pixuna virus. Cytoxantreated (Cy) hamsters develop...

Waterlogging reduces shoot and root growth and final yield of wheat. Waterlogged sites have a combination of low slope, high rainfall, heavy texture and low permeability. This study was aimed the importance of waterlogging on root growth and wheat yield. In order to study the effects of different waterlogging duration (0, 10, 20 and 30 days) at growth stages (1-leaf stage, tillering stage and s...

An algebra $mathbf A = langle A, to, 0 rangle$, where $to$ is binary and $0$ a constant, called an implication zroupoid ($mathcal{I}$-zroupoid, for short) if $mathbf{A}$ satisfies the identities: $(x to y) z approx [(z' x) (y z)']'$, $x' : x 0$, $ 0'' 0$. These algebras generalize De Morgan $vee$-semilattices with zero. Let $mathcal{I}$ denote variety of zroupoids. The investigations into struc...

We measured the discrimination threshold (delta theta)Th for angle theta, where theta was either the angle of a Vee composed of two straight lines contained within the frontoparallel or the angle intersection of two straight lines contained within the frontoparallel plane. The two-line pattern was rotated bodily through a random angle between trials with the aim of eliminating the absolute orie...

The Borodin–Kostochka Conjecture states that for a graph G $G$ , if Δ ( ) ≥ 9 ${\rm{\Delta }}(G)\ge 9$ and ω ≤ − 1 $\omega (G)\le {\rm{\Delta }}(G)-1$ then χ $\chi . We prove the P 5 gem $({P}_{5},\text{gem})$ -free graphs, is, graphs with no induced ${P}_{5}$ K ∨ 4 ${K}_{1}\vee {P}_{4}$

Pembelajaran abad 21 menuntut keterampilan berpikir tingkat tinggi meliputi 4Cs (critical thinking, communication, collaboration, and creativity) sehingga dibutuhkan inovasi pembelajaran salah satunya dengan LKPD. Tujuan penelitian adalah mengembangkan LKPD berbasis Vee Mapping pada materi sistem pernapasan yang valid dan praktis sebagai bentuk Pendidikan biologi. Penelitian ini menggunakan met...

The objective of this article is to present and illustrate an educational engineering approach relating the use structure (SD), activity (AD) Vee (V) diagrams in design modeling scenarios. alignment with a model hybrid pedagogical approach: explicit - by discovery strongly requested recently practices distance online education. We first analyze basic education, then we how these scriptwriting.
