Some pathogenic species of the Botryosphaeriaceae have a latent phase, colonizing woody tissues while perennial hosts show no apparent symptoms until conditions for disease development become favorable. Detection of these pathogens is often limited to the later pathogenic phase. The latent phase is poorly characterized, despite the need for non-destructive detection tools and effective quaranti...
TiO2 nanoparticles about 20 nm in diameter in the form of anatase were prepared and characterized. The nanoparticles were successfully dispersed into a paraffin wax (PW) matrix without any surfactant. The differential scanning calorimetric instrument and the transient short hot-wire method were used to measure the thermal properties of the TiO2/PW composites. It is found that the phase-change t...
this study focuses on the preparation and modification of a thin-film composite (tfc) hollow fiber polyamide membrane fabricated by the interfacial polymerization of piperazine (pip) and trimesoyl chloride (tmc) on a porous polysulfone substrate. the effects of triethylenetetramine (teta) and silica nanoparticles (sio2) contents in the aqueous phase (as the additives) on the morphology and perf...
Aurone synthase (AUS), a member of a novel group of plant polyphenol oxidases (PPOs), catalyzes the oxidative conversion of chalcones to aurones. Two active cgAUS1 (41.6 kDa) forms that differed in the level of phosphorylation or sulfation as well as the latent precursor form (58.9 kDa) were purified from the petals of Coreopsis grandiflora. The differing active cgAUS1 forms and the latent cgAU...
OBJECTIVE To study the activity of the human uterine cervix at the onset of labour and further characterise cervical asynchronous electromyographic (EMG) activity in the latent phase. DESIGN Prospective observational study. SETTING AND PARTICIPANTS Clinical hospital in Ljubljana. PARTICIPANTS Forty-seven healthy nulliparous women with relatively unripe cervices requiring induction of labo...
Despite prolonged antiretroviral therapy, HIV-1 persists as transcriptionally inactive proviruses. The HIV-1 latency remains a principal obstacle in curing AIDS. It is important to understand mechanisms by which HIV-1 latency is established to make the latent reservoir smaller. We present a molecular characterization of distinct populations at an early phase of infection. We developed an origin...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
A new type of single-phase stand-alone induction generator using a three-phase induction machine and a single-phase voltage-source PWM inverter is introduced. The generator scheme is capable of producing constant load frequency with a very well regulated output voltage. A small lead acid battery and a single-phase full diode-bridge rectifier are used to feed the inverter. The inverter feeds one...
The Biologist (Lima) ISSN Versión Impresa 1816-0719 ISSN Versión en linea 1994-9073 ISSN Versión CD ROM 1994-9081 235 The Biologist (Lima), 2011, 9 (2), jul-dic: 235-240. The aim of this study was to detect patients with latent TB in high-risk HIV positives (HIV +) in the city of Lima, Peru in order to provide this population with appropriate treatment to avoid complications from HIV-Tuberculos...
background: monitoring of indicator and pathogenic microorganisms is essential for proper composting. the aim of this study was to evaluate the change in population of coliform bacteria and salmonella spp. in composting process of municipal wastes and after its application on soil. methods: the samples were taken from each raw waste pile, initial pile, and active phase pile, cooling phase pile ...
