Abstract:
ABSTRACT Viruses are believed to be significant pathogens for phytoplankton. Usually, they infect a single algal species, and often their infection is highly strain specific. However, the detailed molecular background of the strain specificity and its ecological significance have not been sufficiently understood. Here, we investigated the temporal changes in viral RNA accumulation and virus-induced cell lysis using a bloom-forming dinoflagellate Heterocapsa circularisquama and its single-stranded RNA virus, HcRNAV. We observed at least three host response patterns to virus inoculation: sensiti

ABSTRACTWe have developed a regulated delayed antigen synthesis (RDAS) system for use in recombinant attenuatedSalmonellavaccine (RASV) strains to enhance immune responses by reducing the adverse effects of high-level antigen synthesis. This system includes a chromosomal repressor gene,lacI, expressed from the arabinose-regulatedaraCPBADpromoter. LacI serves to regulate expression from a plasmid promoter, Ptrc, that directs antigen synthesis. In the presence of arabinose LacI is produced, which binds to Ptrc, blocking antigen synthesis.In vivo, an arabinose-poor environment, the concentration

Underground excavations break the balance of the initial stress field and cause stress redistributions in the surrounding rock masses. Problems normally arise as the stress exceeds the rock mass strength. In addition, the rock mass contains preexisting defects, such as the fissures, fractures, joints, faults, shear zones, dikes, etc., which could significantly weaken the rock mass strength and make the rock mass behavior complicated. The stability of underground excavations is of great importance to an operating mine project since it ensures the safety of the working environment and the succes

Abstract A confined aqueous environment is defined by a very low water-volume to exposed steel-area ratio. In such media containing dissolved CO2, siderite is formed and acts as a protective film. An addition of applied stress and/or environmental fluctuation can disturb the balance between the steel and this protective film, causing the fracture of the latter and leading to Stress Corrosion Cracking (SCC). The material studied is a cold drawn and rolled high strength steel composed of ferrite and spheroidized pearlite and has a strong microstructural anisotropy due to the specific cold work p

We report on the site-controlled Purcell-enhanced quantum emitters in hexagonal boron nitride by strain-induced activation in gold-coated silicon nanoposts. The room temperature emitters show a second-order autocorrelation function value at zero time delay of down to 0.29, lifetimes shortened to 0.5 ns, and single photon emitter yield of 28%.

Abstract:
The efficiency of zinc oxide nanoparticles (ZnO-NPs) in inhibiting Phytophthora spp. growth in both durian fruits and stems is demonstrated. The size of ZnO-NPs used was in range of 25-50 nm in diameter. Diseased durian sample were collected from a durian orchard located in southern of Thailand. The pathogen of diseased durian was isolated for subsequent morphological identification. Three distinct strains of Phytophthora spp. (designated as PHY41, PHY45, PHY49) were successfully isolated and were found in colonies with rings and stellate pattern, ovoid, limoniform sporangium with semi-papilla

Abstract:
Abstract Injection of nitrate into an oil field can significantly reduce the concentration of sulfide produced by endogenous sulfate-reducing bacteria (SRB). Although much is known of the effects of nitrate in relatively high temperature reservoirs (60-80 °C), flooded with seawater, its effectiveness in lower temperature reservoirs (30-40 °C) subjected to produced water reinjection (PWRI) is less well understood. The nitrate-reducing, sulfide-oxidizing bacterium (NR-SOB) Thiomicrospira sp. strain CVO, was isolated from such a reservoir. This organism converts sulfide and nitrate into sulfate a

Antimicrobial activity of Moldovian selected strains of streptomycetes revealed that the growth of test cultures was actively delayed by 11 Streptomyces strains. Strain Streptomyces sp. 9 caused the formation of zones of lacking growth in 6 out of the 11 phytopathogens tested. Metabolites of the strains Streptomyces spp. 10 and 33 completely suppressed Alternaria alternata growth, while Streptomyces spp. 10 and 17 – Botrytis cinerea, strain Streptomyces sp. 10 – Fusarium graminearum. Growth of Clavibacter michiganensis was completely suppressed by the metabolites of the strain Streptomyces sp.

Abstract:
Piezoelectric transducers have been used for semi-active vibration reduction in structures by altering the stiffness state and dissipating electrical energy. Common approaches include state switching, synchronized switch damping on a resistor (SSDS), and synchronized switch damping on an inductor (SSDI). Each of these methods requires four switches per vibration cycle, so any delay in the switch from the ideal moment could have a significant effect on the vibration reduction. An experimental investigation into the effect of switch delays on these techniques reveals that the abrupt change in pi

Abstract:
The project was primarily experimental in nature. It has utilised small scale specimen and ring expansion testing rather than full scale vessel tests to investigate the mechanisms responsible for time-delayed failures. The aim was to perform a series of laboratory experiments to investigate the influence of pre-strain and cyclic frequency on the behaviour of pipeline steels subject to low cycle fatigue and sustained loads. The initial experimental programme consisted of tensile tests and fatigue crack growth tests including tensile dwell periods, carried out on pre-strained and non pre-straine

The objectives of the current work are to (1) provide an assessment of the capabilities of the nonlinear harmonic (NLH) method to detect gouged dents in pressurized pipelines; (2) rank the severity of the detected defects against delayed failure; (3) provide information related to the remaining lives of detected defects when fatigue damage from cyclic pressure changes is the time-dependent mechanism controlling delayed failure; and (4) transfer the developed NLHbased defect severity criteria to an inline inspection vendor, Tuboscope Pipeline Services.

Abstract:
The FAO has projected a doubling in world demand for seafood during the 21 ed from aquaculture of marine fish and shrimps fed primarily on fishmeal-based aquafeeds. However, current practices of high intensity monoculture of shrimp in coastal ponds and fish in offshore pens have been strongly criticized as being ecologically and socially unsustainable. This view derives from un- checked eutrophication of coastal marine ecosystems from fish farm effluents, and the destruction of coastal estuarine ecosystems by shrimp farm constructions, plus aquaculture’s reliance on wild-caught small fish - wh

Linear city bus services are facing increased challenges from city growth. Increased number of inhabitants on increasing acres of built-up areas, makes it demanding to maintain adequate bus services within reasonable catchment areas. Number of departures per hour give a partial description of the bus service quality. Number of departures give reference to the time aspect of bus service quality, but say nothing about the geographical aspect. What part of the entire line network is within reach of direct bus service when frequencies are limited? To address the geographical aspect of bus service

Faced with the acceleration of the digital economy, the governance and effective sharing of data have become fundamental issues for public policy at all levels of jurisdictions and in all areas of human activity. This paper reviews the initiatives and challenges associated with data governance, with a particular focus on the European Common Data Spaces (ECDS) and their direct relevance to the Canadian context. It explores the inherent complexity of data governance, which must reconcile sector-specificities with more horizontal governance principles. In doing so, it highlights the importance of
