Kiwifruit (Actinidia spp.) is a perennial fruit tree, and the fruit of kiwifruit is economically and nutritionally important worldwide. To date, approximately 23 species of kiwifruit viruses have been reported worldwide. As for the detection method for kiwifruit viruses, previous reports mostly used the single RT-PCR detection method. In the detection of kiwifruit viruses, multiplex RT-PCR has the advantages of being fast, reliable and inexpensive. In this study, a stable, efficient and reliable multiplex RT-PCR method for the detection of the five most common kiwifruit viruses was established. The concentrations of Mg2+ and HS-Taq and the annealing temperature in the multiplex PCR system were optimized. The results indicate that the optimal annealing temperature was 56 °C; the optimal concentration of added Mg2+ was 2 mM; and the optimal concentration of HS-Taq was 1.0 U/μL. The stability of the optimized multiplex RT-PCR system was verified by field sample testing, and the results showed that the multiplex RT-PCR system was stable, efficient and reliable. This will provide much convenience for the detection of kiwifruit viruses in the future.

A recent preoccupation with space and place has drawn together theorists and workers in a wide range of disciplines, including human geographers, archaeologists, architects, cartographers, psychoanalysts, sociologists, poets, novelists – and theatre practitioners. There are therefore a range of lenses, a range of vocabularies, through which site-specific theatre and performance can be considered. In this article, Cathy Turner focuses on Mike Pearson's descriptions of site-specific work, particularly his involvement with archaeology, before proposing that we might find a useful, complementary vocabulary within psychoanalytic theories of object relations. She refers to performances by Lone Twin and to her own work with site-specific company Wrights & Sites, who created An Exeter Mis-Guide and A Courtauld Mis-Guide in 2003. Cathy Turner has produced a number of site-specific ‘mis-guided walks’, tours, and performances in her work with Wrights & Sites since 1998. She recently completed a Research Fellowship at Exeter University, investigating writing processes in contemporary performance, including site-specific work. She is now a Teaching Fellow at Exeter University and an Associate Lecturer at Dartington College of Arts.

I have square plates and round ones, some with distinctive edges and others that are very simple. It's important to note that no matter how pretty the pattern on a plate might be, if it's right smack in the center, then it's just going to be hidden when the food is served. So my \"photo op dishes,\" as I call them, need to have interesting borders -- color, shape, or both -- but plain centers. I spend an inordinate amount of time pulling plates in advance of the photo shoots, stacking them with others for contrast, rearranging them all until I feel that the theme is set. My Jan. 26 story about Caribbean dishes was easy to plate, though: Everything was white like the sand of the beaches and turquoise like the sparkling water. The story last spring about Jacques Ppin's Authors! Authors! appearance, which featured recipes from his cookbooks, was the perfect occasion to use all the plates I have with French phrases written on them, such as \"tarte aux crises\" and \"salade verte.\"

Mr [Michael Pearson]'s downfall has been as spectacular as that of [Valeant], which has lost almost 90 per cent of its value since last summer. A former management consultant, he took Valeant from relative obscurity to a permanent position in the headlines in the financial press - initially for its aggressive merger and acquisitions policy, founded on cheap debt. Valeant's problems didn't end there. Just as its pricing policy was beginning to gain wider (and unpleasant) attention, so its other business practices were being called into question. A California-based equity research company, Citron, drew attention to Valeant's reliance on a shady sales partner, Philidor, resulting in a forced restatement of earnings.

The truth has long been out there for anyone willing to look. Rival Allergan, which [Valeant] attempted to buy for $45bn in 2014, rejected the offer in part because its board felt that Valeant's business model - aggressively leveraging its balance sheet to buy rivals, and then raising drug prices - was \"not sustainable\". That appears to be putting it mildly. Speaking of its investors, Bill Ackman's Pershing Square hedge fund now has board representation. Scant consolation perhaps - Valeant has cost Pershing around $2bn in losses since last summer, and Mr Ackman's reputation has taken a severe beating along with it. But it's easy to forget that Valeant's shareholders and stakeholders also include a lot of people whose livelihoods are threatened - people who don't have a golden parachute. Given that Instagram is owned by Facebook, it was probably only a matter of time before it changed the way in which its 400 million users view posts - from chronological order to algorithm-based. So rather than see photos and videos in the order in which they are uploaded, Instagram users will now see them in the order that Instagram thinks they want to see them, whether they want to or not.

\"We have dates of around 3400 BC for [Craig Rhos]-y-felin and 3200 BC for Carn Goedog, which is intriguing because the bluestones didn't get put up at Stonehenge until around 2900 BC,\" he said. \"It could have taken those Neolithic stone-draggers nearly 500 years to get them to Stonehenge, but that's pretty improbable in my view. It's more likely that the stones were first used in a local monument, somewhere near the quarries, that was then dismantled and dragged off to Wiltshire.\" The dating evidence suggests that Stonehenge could be older than previously thought, [Mike Parker Pearson] said. \"But we think it's more likely that they were building their own monument [in Wales], that somewhere near the quarries there is the first Stonehenge and that what we're seeing at Stonehenge is a second-hand monument.\" There is also the possibility that the stones were taken to Salisbury Plain around 3200 BC and that the giant sarsens -- silicified sandstone found within 20 miles of the site -- were added much later. \"Normally we don't get to make that many fantastic discoveries in our lives,\" Parker Pearson said. \"But this is one.\"

\"If someone asks me something, I say, 'Why not?'\" said the Orleans resident. \"I've officiated weddings, gone to South Africa. When someone asks you to do something, you never know where it will lead. That's how I ended up here.\" \"I used to do it just for fun,\" he said. \"And the next thing you know, I'm announcing the FIFA World Cup ... here's a bigger microphone and here's a bigger stadium.\" \"My kids always said I should have got into radio, and I never found the time to do it,\" [Michael Pearson] said. \"It's a great way to be loud and have fun. Some people play chess. Some people ride a bike. I announce in a giant stadium.\"

\"Here\" is the announcing booth on the fourth level of the stands at TD Place, where he calls all the Fury FC soccer games - and recently found himself announcing the FIFA Women's World Cup as well. \"I used to do it just for fun,\" he said. \"And the next thing you know, I'm announcing the FIFA World Cup ... here's a bigger microphone and here's a bigger stadium.\" \"That was a little more nervewracking,\" he said. \"But the Thai embassy said I did a good job.\"
