the carob moth, ectomyelois ceratoniae (zeller), belongs to the family pyralidae and the subfamily phycitinae. in spite of some features of sexual dimorphism in size and shape in the order lepidoptera and the mentioned family, it has not been recorded in this species. in the current study, sexual dimorphism in the wing shape and size of carob moth on four hosts (pomegranate, fig, pistachio and ...

To study the association of autoimmunity and human B cell neoplasia, we have established a model of a B cell lymphoma which expresses a pathogenic autoantibody of defined specificity. The Ig VH gene expressed in this neoplasm was analyzed longitudinally using clinical specimens taken from the splenic lymphoma (S) at diagnosis and from lymph node relapses 3 and 4 yr later (N3 and N4). Southern a...

The nonlinear coefficients, n4, of the time-dependent refractive index for argon are calculated in the non-resonant optical regime. Second-order polynomial fitting of DC-Kerr, γ((2))(-ω; ω, 0, 0), electric field induced second harmonic generation (ESHG), γ((2))(-2ω; ω, ω, 0), and static second-order hyperpolarizability, γ((2))(0; 0, 0, 0), is performed using an auxiliary electric field approach...

The objectives of the study were to determine distribution heavy metal contamination in water, sediments and biota (Callinectes amniciola) upper reaches Bonny Estuary impact on physicochemical characteristics water body. Sampled was from January June 2020. parameters varied slightly across months but within FEPA/WHO (2003) acceptable limits. Furthermore; compared seasonal variations determinati...

Extensive wind tunnel tests are conducted to evaluate surface pressure distribution of a semi span swept wing. The wing section has a laminar flow airfoil similar to NACA 6-series airfoils. The investigations are conducted at various speeds and angles of attack. Surface pressure distribution over the wing upper surface is measured for both chordwise and spanwise sections. Statistical analyses a...

Flying is an ecologically important behaviour in many insects, but it often results in permanent wing damage. Although wing wear in insects is often used as a method to determine insect age, and is associated with an increased risk of mortality, the causes of wing wear are unresolved. In this paper, we examine whether wing use while foraging explains wing wear in bumble bees (Bombus spp.). Wing...

Let (x, y, z) be a rectangular coordinate system, with +x in the direction of the undisturbed freestream flow velocity, +y normal to the plane of the thin wing, and z in the direction of the " span " of the wing. The wing is located on the y = 0 plane, " centered " at z = 0. We are given a large aspect ratio wing with the following information: Planform of the wing is described by c(z), the cho...

The data presented in this article relates to the research article, "Evidence of Varroa-mediated Deformed Wing virus spillover in Hawaii" (Santamaria et al., 2017) [3]. The article presents data collected throughout August 2014 to November 2015, on the two Hawaiian Islands of Oahu and Maui. Apis and non-Apis specimens - a total of four species - were collected and tested for Deformed Wing virus...

BACKGROUND The brown planthopper (BPH) Nilaparvata lugens (Stal) is a serious pest of rice in Asia. Development of novel control strategies can be facilitated by comparison of BPH feeding behaviour on varieties exhibiting natural genetic variation, and then elucidation of the underlying mechanisms of resistance. METHODOLOGY/PRINCIPAL FINDINGS BPH feeding behaviour was compared on 12 rice vari...
