Are organic poultry farms more sustainable than conventional farms?

There are conflicting opinions over which farming system delivers the most sustainable method of poultry farming – and much of this is due to the many different definitions of “sustainable”. When comparing the sustainability of conventional and organic poultry farming systems, most people will have an opinion on which approach they think is better. Some may view the impressive efficiency of conventional indoor systems as more sustainable in terms of optimised output and business practice, while some may view the “naturalness” of organic systems as best for the environment and thus more sustainable from the point of view of ecology and resource management. However, the findings of a recent study suggest that neither is clearly better than the other, and the solution may lie in combining the best aspects of both systems (Animal (2017), 11:10, pp 1839–1851). Determining the sustainability of a farming system is a complex procedure. Not only must the researchers consider the impacts of each system on the environment and animal welfare, but also the impacts on economic indicators, productivity and public health throughout the entire production chain. According to the researcher...

Apple Adding iPad 2 to Vintage and Obsolete Products List on April 30

i really hate this move by apple, i understand that it gets to a point that the device can’t be supported any more because the hardware will be old and obsolete, then it it will run the latest software very slow, or it might not run at all, but at least let the hardware have a honorable death instead if just killing it because it reach certain age, apple strategy forcing people to upgrade and buy new devices, mean while you can install mojave even on a core 2 duo and run it at a considerable acceptable speed, if you use an SSD , yes the core 2 duo can be nirmally use up to High Sierra but by only using one file from High Sierra ob Mojave you can run mojave on a core 2 duo and that CPU is more than 10 years old, so how can a 5 year old pc or device can be obsolete, they don’t even try or test fir compability, they simply discard the device, add it to the black list list, call it a day and let just wait untill our beloved apple fans buy new devices you guys can clap now is all right Tim i already have the latest Mac Pro, one that i build myself, worth every penny, fully upgradable with water cooling I got the impression that the iPad 2 was sold into schools and/or corporations for...

Chemical control of xylem differentiation by thermospermine, xylemin and auxin

The vascular precursor cells of the procambium differentiate to form continuous vascular strands, from which xylem and phloem cells are generated in the proper spatiotemporal pattern. Procambium formation and xylem differentiation are directed by auxin. In angiosperms, thermospermine, a structural isomer of spermine, suppresses xylem differentiation by limiting auxin signalling. However, the process of auxin-inducible xylem differentiation has not been fully elucidated and remains difficult to manipulate. Here, we found that an antagonist of spermidine can act as an inhibitor of thermospermine biosynthesis and results...

Tesla’s new China factory is slated to produce the Model 3 by 2019 end. Chinese demand

Tesla’s new China factory is slated to produce the Model 3 by 2019 end. Chinese demand for the Model 3 has been weak and 2020 China losses should be -$490m. The terms of Tesla’s contract with China are draconian. If Tesla can’t generate a 15% pre-tax margin by 2023, the government takes back the factory. Handing back the factory could lead to a $2bn write-off or 38% of June-end equity. Tesla put shareholders’ capital at risk by agreeing to China’s lofty terms. Cnc Door Paint Machine High Quality Supplier There are over 27 new EVs scheduled to launch by 2020 end, the majority of which will head to China. Tesla could see its undoing in a market with such fierce competition. With Model 3 sales falling in the US, the additional losses booked in China should lead to a 2020 net loss of -$3.3bn. Financing should be inevitable by Q1 2020 end. Tesla (TSLA) is preparing to start Model 3 production at its Shanghai Gigafactory 3 (GF3) by year-end and Tesla fans are excited about China becoming the Furniture Spraying Machine, Auto Spraying Line, Paint Drying Equipment – Godn,https://www.godnmac.com/

The Global Blow Molded Plastics Market to Generate Revenues of Around $137 Billion During the Period 2020 −2025

CHICAGO, Feb. 13, 2020 /PRNewswire/ — According to Arizton’s recent research report, Blow Molded Plastics Market – Global Outlook and Forecast 2020-2025 is expected to grow at a CAGR of over 4% during the period 2019−2025. 1.  A large part of the transaction of blow-molded plastic takes place at the production facility (spot decision made outside of the contractual agreements). Hence, the industry is characterized by both contractual and spot transactions. 2.  Bio-PET bottle is over 45% costlier than petroleum-based PET bottles. Currently, vendors exhibit a high preference for non-food bio-based bioplastic suppliers than food-based feedstock suppliers, as the cost difference between the two is over 30%. 3.  The transfer of higher raw material cost to customers by way of increasing the packaging cost is not instant and there exists a time lag of about 1 to 1.5 months. This transfer is independent of the client (long-term or one-off customers). 4.  The pressure to introduce more non-virgin materials into the production process is high. However, at the micro-level, the adoption of alternate materials is very low and their growth is not expected to be very signific...

Everything you need to know about the NFL’s helmet guidelines and restrictions – Canal Street Chronicles clock menu more-arrow no yes Horizontal – White Follow Canal Street Chronicles on Twitter Follow Canal Street Chronicles on Facebook Search Horizontal – White Horizontal

The NFL will require players to wear only certain approved helmets this upcoming season. Those who love their old helmets will have to adjust to the new ones, or they won’t be allowed on the field for practices or games. If you haven’t heard about the NFL’s recent enforcement of helmet safety guidelines, you may have missed one of the most interesting, and at times ridiculous, storylines of this 2019 season. Following a one year grace period where old helmet styles worn by players like Aaron Rodgers, Tom Brady, and Larry Fitzgerald were grandfathered in, the NFL is finally enforcing its rule that players can only wear models approved by the league and players’ association. The NFL and NFLPA collaborated to assemble a skilled team of bio-mechanical engineers who for the past five years have been testing the protective levels of dozens of models of football helmets. The best performing helmets are labelled green. Suitable, but less protective models are labelled yellow, while the models labelled red are now completely prohibited from any field of play. Older models, like Tom Brady’s Riddell VSR-4, used traditional foam padding. Newer models typically use Thermoplastic Urethane Cus...

Semi Automated Parallel Lapping of Electronics for Microscopic Examination by Buehler

Failure analysis and production control are key steps in any successful product development. However, revealing the area of interest for microscopic investigation in a multilayer integrated circuit, stacked package or interconnections between solder balls (BGA) in packaged components requires a great deal more precision than typical metallographic preparations. The material removal has to be controlled. It is necessary to gently remove each layer of material and to be able to stop the process precisely at the failure or feature of interest. If a defect is removed from the sample due to excessive grinding, it may persist in production and lead to large losses of money. Parallel material removal or parallel lapping is usually done manually, enabling the operator to continuously examine the surface. Each time the operator must confirm the layer of interest is not yet exposed and that the surface is still parallel.This takes time and an operator with great skill. Automating parallel material removal provides the operator with control. The risk of passing the area of interest is reduced and time saved. This Sum-Note will focus on automated parallel material removal with Buehler’s MPC...
