The reduction in ocean freight from Asia is also a reflection of economic fears that are persisting in spite of the failure of a deep recession to materialize. At the same time, Barraco says, there’s a push to rely more on regional suppliers that are closer to end markets - a reversal of the previous trend toward wholesale offshoring. High oil costs have made it more expensive to maintain the greenhouses in which much of that product is grown, Barraco says.Īs risk management rises to the top of executives’ list of concerns, supplier diversification becomes the order of the day. More recently, the war in Ukraine put a damper on the importation of certain types of produce, such as tomatoes and cucumbers, from the United Kingdom. That said, Central and South America have long been strong source of fruits and vegetables for the North American market, providing avocados, pineapples, papayas, bananas, cocoa and coffee. Gary Barraco, e2open’s assistant vice president of product marketing, said the latest edition of the ocean index added South American ports to its statistics, a reflection of the shift in sourcing imports away from Asia. Despite the rate reductions, higher inflation continued to plague transportation markets, the report noted, cautioning shippers against place too much reliance on the volatile spot market instead of making solid commitments to carriers. A likely reason for the decline was the continued steady drop in diesel fuel prices, down nearly 30% year-over-year, although still higher than in previous years. Spot rates fell in April by 2.6% from the prior month, and by 17.9% year-over-year. Primary tender acceptance by carriers rose in April by 0.9%, to 94.3%, while on-time performance continued to increase, “and is sitting at or above pre-COVID levels for the first time in nearly three years,” the report said. Refrigerated transport rates also fell, albeit less dramatically: 1.3% from the previous month, and 20.7% year-over-year.Īvailability of both truck space and service quality was up. According to e2open’s latest Road Freight Market Index, truck capacity for agricultural goods remained “plentiful” in April, “while spot rates continue marching toward record lows relative to the rate index.” Dry van rates were down by 7.2% over the previous month, and a whopping 35.9% from April of 2022. Over-the-road shippers experienced some additional good news. The reason for the marked improvement in carrier and terminal service, as reflected in shorter booking and transit times, was an overall decline in demand for goods shipping out of Asia. In the first quarter of 2023, the global average time from initial booking aboard ship to clearing the gate at the port was 60 days - down five days from the fourth quarter of 2022, and 12 days from the first quarter of last year. The latest Ocean Shipping Index from e2open, covering the first quarter of 2023, finds a significant reduction in the time it takes “to deliver goods to truck or rail carriers after booking with an ocean carrier and completing the cross-ocean journey.” Total booking-to-receipt time for cargoes moving from Asia to North America shrank by 11 days from the previous quarter, and 24 days from same quarter of 2022.Īlso notable was a reduction in the time it takes for inbound cargo to be unloaded from a ship to when it leaves the marine terminal for movement inland, e2open said. What’s more, the numbers suggest the beginning of a shift in sourcing away from Asia, in favor of points in North America. Importers that struggled with tight carrier capacity and soaring freight rates during the COVID-19 pandemic are finally seeing some relief on the service side, according to a pair of new reports on trends in ocean and road transportation.

8/14/2023 0 Comments Worx hedge trimmer 20vIt’s about proof-reading, fact-checking and continuously researching everything we publish, ensuring that it adheres to our editorial standards, so that everyone can really get the most out of their green space. Sarah’s role as chief editor at DIY Garden is about more than just making sure we’re literally dotting the i’s and crossing the t’s (although she’s a stickler for detail, so it’s certainly about that too!). It also made light work of brambles and holly, but when I attempted to prune thin branches on a cherry tree with it, the branches were left looking rather chewed up. When I used this hedge trimmer on areas of the hedge that were thinner and more spindly, I didn’t have this issue. However, I often had to use a bit of force to persuade it to slice through my thick beech hedge, which other hedge trimmers ran through like butter. With 16mm teeth spacing coupled with diamond ground blades, this really shouldn’t have been the case. I also noticed that, unlike the other hedge trimmers that I tested, this one struggled with thicker branches. While it does come with a shoulder strap, this doesn’t make the task much easier. This not only makes it difficult to balance the machine in a way that gives you a smooth, sweeping cut, but it also gets very tiring if you use the hedge trimmer for long periods of time. However, I have to say that there were a couple of different aspects that let this Worx model down.įirstly, the heavy head that I mentioned. In many ways, the design of this machine is very similar to that of the VonHaus hedge trimmer that I tested, so I was expecting the two of them to perform in similar ways. This makes it one of the longest hedge trimmers that I’ve tested, which is ideal for those of you with tall hedges. In terms of reach, this hedge trimmer extends to 2.8m. This simple little feature may not seem like much, but it should provide good manoeuvrability – you won’t need to twist your hand around when cutting, since you’ll be able to simply turn the handle instead. Not only does the head of this hedge trimmer tilt to 8 different positions, which is more than you get with most other brands, but the rear handle at the base can also be rotated with the press of a button. Its 45cm blades are diamond ground, which usually means that the blades will be extremely sharp – ideal for a clean finish. However, other than that, the rest of this hedge trimmer’s design features were pretty impressive. What made this worse was the lack of a D-handle – instead, there’s just a rubberised section of the pole that you hold on to instead. This made the machine feel more unbalanced when I was holding it. It only takes a minute or two to assemble and doesn’t require much know-how, making it ideal for those who aren’t already familiar with hedge trimmers.Īs soon as I had put this machine together, I noticed that it had quite a heavy head. While we aim to supply accurate product information, it is sourced by manufacturers, suppliers and marketplace sellers, and has not been provided by Overstock.While some hedge trimmers are designed with a few different parts that you need to put together, this Worx model came in two halves – simply slot them together, flick the orange clips to tighten them in, and you’re good to go.

Let’s call it an even 49 thoughts per minute. (Again, these studies are not peer-reviewed, and only serve as a rough estimate.) Researchers at the lab conducted some rudimentary experiments with student test subjects and electrophysiological monitoring, and found that the average person has about 48.6 thoughts per minute. It remains unknown exactly how many thoughts we have each day - or what even constitutes a “thought” for that matter.īut there are some estimates out there, and the best one comes from the University of Southern California’s Laboratory of Neuro Imaging. Calculating thought incomeĪs of 2016, we humans have only scratched the surface of the science of our thought process. So, in our hypothetical situation, we still get one penny (in 2016 dollars) per thought. Unfortunately for us, today’s idiom remains the same: It has not taken inflation into account. Adjusted for inflation, it would amount to about 1.6 pounds, or $2.50 USD, today. When these texts were written, a penny was actually a considerable sum in England. Twenty-five years after More’s book, a playwright named John Heywood put together a collection of proverbs he’d heard over the years ( The Proverbs and Epigrams of John Heywood).īuried in its pages, beside gems like “Rome was not built one day” and “all that is well ends well,” was “a peny for your thought.” This text, from 1547, popularized “A penny for your thoughts.” “The Proverbs and Epigrams of John Heywood,” John Heywood, 1547 ’” The very first use in print of the idiom “A penny for your thought(s).” “Four Last Things,” Sir Thomas More, 1522īut it wasn’t really until 1547 that the saying gained any popularity in usage. “As it often happeth that the very face sheweth the mind walking a pilgrimage, in such wise that, not without some note and reproach of such vagrant mind, other folk suddenly say to them, ‘ A penny for your thought. In his text, he uses the saying to refer to a pensive vagrant on a pilgrimage: A brief history of the idiom “A penny for your thoughts”įirst used by English statesman Sir Thomas More in his 1522 book Four Last Things, the idiom “A penny for your thoughts” has retained the same meaning for nearly 500 years. And I couldn’t help but speculate: What if the idiom were economically redeemable not just for musings spoken aloud, but the thousands of rapid-fire internal thoughts that go through my mind each day? If I got a penny for every thought I had, how rich would I be? But the idiom - a penny for your thoughts - lingered. We struck up a conversation, then, two stops later, went our separate ways. Last weekend, as I was pensively staring into nothingness on the DC metro, a stranger approached me and said, “A penny for your thoughts?” 8/14/2023 0 Comments Super mario crossover 5It is much more difficult to JUMP up into a 1 brick size hole.

The huge positive response that this game received has changed my life, and it made it possible for me to form a development team and turn Exploding Rabbit into a production studio. I would like to take a moment to thank everyone for making Super Mario Bros. As Super Retro Squad gets further along in development, it will be more difficult for any team members to devote time to this free game when it is filled with intellectual property that we do not own. More levels and skins will certainly be added to the game in the future, but I would probably consider this the last major release. Blaine will now be the lead developer, and I will be spending nearly all of my time on Super Retro Squad. I now wish to inform people that it is time for me to move on, so I will no longer be playing a large role in the development of this game. This game has gotten bigger than I ever thought it would, and much of that is thanks to the help of Zach Robinson and Blaine Hanna. The only limitation of playing the game on other websites is full-screen mode it will only work on our site. You are free to put the game anywhere you like. We are also pleased to announce that the game will no longer be locked to our website. For a full list of changes, see the version history page. Some other notable features are a new difficulty system, a new skin selection system, full-screen support, and several new skins. With the inclusion of difficulty-based maps, there are now 192 levels in the game. This is our biggest update so far, and it features an entirely new set of levels from Super Mario Bros.
