The T-DNA of the Ti plasmid of Agrobacterium is flanked by 25-base-pair imperfect direct repeats that are required in cis for transfer to the genome of the plant host. Another sequence, designated overdrive, is located adjacent to the right-border repeats and functions in cis to enhance tumor formation. We have examined the effect of the overdrive sequence on the early steps in T-DNA processing...

The extended invited papers were duly reviewed which resulted in four accepted papers for this special issue. The theme of this special issue of IJEGR is an Overview of the State of the Art and Future Trends in ICT Innovation for Business-to-Government Interaction, which can be further detailed as follows. Government supervision and enforcement authorities, such as customs, tax, police, and foo...

South Africa (SA), like the rest of the Southern African Development Community, has a high prevalence of communicable diseases, an increasing non-communicable disease burden, and diverse internal and cross-border population movements. Healthy migration is good for development, but current prevention, testing and treatment responses within public health systems - particularly for chronic conditi...

Using new data on citations to university patents and scientific publications, and measures of distance based on Google maps, we study how geography affects university knowledge diffusion. We show that knowledge flows from patents are localized in two respects: they decline sharply with distance up to about 100 miles, and they are strongly constrained by state borders, controlling for distance....

The measurement of wellbore annulus gas-liquid two-phase flow in CBM (coalbed methane) wells is of great significance for reasonably developing gas drainage and extraction processes, estimating CBM output, judging the operating conditions of CBM wells and analyzing stratum conditions. Hence, a specially designed sensor is urgently needed for real-time measurement of gas-liquid two-phase flow in...

Productivity is a key weapon for manufacturing companies to stay competitive in a continuous growing global market. Increased productivity can be achieved through increased availability. This has directed focus on different maintenance types and maintenance strategies. Increased availability through efficient maintenance can be achieved through less corrective maintenance actions and more accur...

Most existing condition based maintenance (CBM) work reported in the literature only focuses on determining the optimal CBM policy for single units. Replacement and other maintenance decisions are made independently for each component, based on the component’s age, condition monitoring data and the CBM policy. In this paper, a CBM optimization method is proposed for multi-component systems, whe...

OBJECTIVE Computerized cognitive behavioral therapy (cCBT) and cognitive bias modification for interpretation (CBM-I) both have demonstrated efficacy in alleviating social anxiety, but how they compare with each other has not been investigated. The present study tested the prediction that both interventions would reduce anxiety relative to a no-intervention comparison condition, but CBM-I would...

Posttraumatic Stress Disorder (PTSD) is characterised by dysfunctional appraisals of the trauma and its consequences including one's own symptoms. Experimental studies have shown that Cognitive Bias Modification-Appraisal (CBM-App) training can reduce dysfunctional interpretations and analog trauma symptoms. One important question is how to enhance the effects of CBM-App. Following work suggest...

Time-varying spectra of three sets of musical instrument tones were data-reduced using two different methods based on critical bands. One method (used for Tests 1 and 2) preserved the average spectrum and rms amplitude-vs-time envelope for each band. The other method (used for Test 3) utilized critical-band smoothing of the spectral envelope. 20 subjects were tested for their ability to discrim...
