Diffusion coefficients for the intercellular movement of fluorescent tracers have been measured in the epidermis of a larval beetle. Fluorescent tracer was injected into a cell and the spread of tracer from cell to cell in this monolayer was recorded by a TV camera. Fluorescence intensities were digitized from the TV images at successive times after the start of injection at various distances f...

Thatcher near-isogenic lines (NILs) of wheat carrying resistance gene Lr2a, Lr3, LrB or Lr9 were inoculated with Puccinia triticina races of virulence phenotype BBBD, MBDS, SBDG and FBDJ. Puccinia triticina infection structures were analysed under the fluorescence microscope over a course of 14 days after inoculation (dai). The relative proportion of P. triticina and wheat genomic DNA in infect...

Isolation of brucellae from blood and other normally sterile body fluids or tissues remains the only irrefutable evidence for the disease, but detection of the organism in clinical specimens is frequently hampered by the low sensitivity of routine culture methods. Because brucellae have the ability to survive and multiply within phagocytic cells, we speculated that phagocytosis of the organism ...

Pembangunan tersebut menimbulkan perubahan fungsi lahan sawah menjadi aspal atau beton hal ini telah mengurangi daerah resapan wilayah hulu Mataram. Perubahan meningkatkan jumlah limpasan didaerah sekitarnya musim hujan sehingga sering terjadi genangan...

One of the principal objectives of vibration isolation technology is to isolate sensitive equipment from a vibrating structure or to isolate the structure from an uncertain exogenous disturbance source. In this paper, a dynamic observer-based active isolator is proposed that guarantees closed-loop asymptotic stability and disturbance decoupling between the vibrating structure and isolated struc...

Article history: Received: 28.11.2014. Received in revised form: 19.3.2015. Accepted: 1.4.2015. In traditional vibration isolation and placement studies, vibration participation of foundation is often ignored, and optimizations are focused on the improvements of isolated object and isolation system. In this paper, clamped thin plate was considered as the foundation, and "machinery equipment vib...

The experimental demonstration of a novel integrated optical isolator concept is presented. By using a transversely magnetized ferromagnetic metal as the electric contact of an active waveguide structure, the transverse magneto-optic Kerr effect induces nonreciprocal loss of the TM guided mode. Based on this principle we designed, fabricated and characterized the first version of an optical iso...

In less-developed countries, studies of bloodstream infections (BSI) have been hindered because of the difficulty and costs of culturing blood for bacteria, mycobacteria, and fungi. During two study periods (study period I [1997] and study period II [1998]), we cultured blood from patients in Malawi by using the BACTEC MYCO/F LYTIC (MFL), ISOLATOR 10 (Isolator), Septi-Chek AFB (SC-AFB), and Sep...
