It’s that time of year again when Australia’s fresh summer fruit is beginning to show up in wholesalers and supermarkets across the country. Apricots, plums, peaches and nectarines in particular, which the Australian horticulture industry classifies as summer fruit. These fruits are all closely related members of the “Prunus” genus and are commonly referred to as stone fruit. Production of these summer fruits totalled 161,044 t for the year ending June 2019. Peaches and nectarines make up the lion’s share of this with 119,775 t produced, followed by plums at 32,241 t and apricots at 9,027 t produced. (Australian Horticulture Statistic Handbook).

There are two key upcoming phases in your stone fruit calendar and they are the fruit fill/pre-harvest and post-harvest stages. There are some key nutrient management practices that can be taken to ensure a good quality harvest and to ensure your trees have the required nutrients available for next seasons bud burst.

Stone fruits size rapidly 2-4 weeks before harvest. During this period it is important to avoid water stress. It is equally important to ensure you supply the right nutrients leading up to and during this period to ensure you have a high yielding, colourful and tasty fruit that will maintain its quality and firmness. Nitrogen should be reduced in this phase to avoid excess vegetative growth and soft fruit. Potassium is important for colour, sugar and starch development and drives yield. Calcium is regularly supplied to the fruits during cell division, usually the first 6 weeks after blossoming. During the cell expansion or fruit fill stage, the calcium is diluted as a result of growth. Due to limited mobility in the tree the leaves are supplied easier than the fruits, therefore foliar calcium is very important to prevent disorders and maintain fruit firmness. It is important to balance these nutrients in the lead up to harvest to ensure neither quality nor yield is compromised. Phosphorus is also important for fruit colour and cell enlargement, and copper and boron aid in the uptake of calcium so ensure adequate levels are present.

Post-harvest is also a key period to apply the nutrients required to support growth after dormancy. Post-harvest nitrogen applications provide the main source of nitrogen at bud burst. Applying some phosphorous in this period ensures good root growth heading into dormancy. Calcium supports strong bud development and some potassium now will assist in bud strength and early fruit set next season. While the leaves are still on foliar apply magnesium and boron. Zinc is important as it governs the production of growth hormones and lifts photosynthetic potential. Post-harvest is a great time to get zinc into your tree’s to support next season’s growth.

There is a fantastic range of products out there to cover your nutrient needs and maximise this year’s crop and prepare for next years. Contact your local agronomist or industry expert to get a plan in place.

First From the production process, it can be seen that the interior of the wear-resistant ceramic composite pipe is an alumina ceramic pipe, and the exterior is a steel pipe, so it can give full play to the advantages of steel pipe and ceramics: steel pipe has high strength, good toughness, impact resistance, and good welding performance. , Corundum ceramics have high hardness, high wear resistance, corrosion resistance, and good heat resistance, which fills the weaknesses of steel pipes with low hardness, poor wear resistance, and poor toughness of ceramics.

Second You can observe the appearance: the wall thickness of the good-quality wear-resistant pipe is uniform without deviation, the ceramic layer on the inner surface is smooth and uneven, and there is no gap between the ceramic layer and the steel pipe. This is a superior product.

Good-quality wear-resistant ceramic composite pipes are uniform in composition, look very regular on the cutting head, and feel smooth to the touch instead of burrs. Therefore, if it is a defective material, it will be uneven on the cutting head, and the entire steel pipe will look dull. If it is a fake and inferior wear-resistant ceramic composite pipe.

Third. There is also the fact that the cross-section of the fake and inferior wear-resistant ceramic composite pipe is not circular, may be oval or other shapes, this is the result of manufacturers saving materials and cutting corners, so this is not suitable Specification of external dimensions. There is also the appearance of scarring, which is not allowed to appear on high-quality wear-resistant ceramic composite pipes, but it is easy to see this phenomenon on inferior wear-resistant ceramic composite pipes.

Speaking to Le Progrès, Lyon President Jean Michel Aulas has slammed his players for sub-par performances in recent weeks.

“The principal people responsible are the players. The lack of confidence is obvious as is this inability to fight back. Are the players aware that they lose value when they are bad? I did not recognize Milan Bisevac. I also saw the errors of Claudio Beauvue, who is having many difficulties even doer Alex’s goal he did a good header. He wanted to join a top club, here he is, but the chemistry with Alexandre Lacazette has not been found.”

Oh, Kylie Jenner, you're always keeping us on our toes. The queen of matte lipstick just posted a video teaser to Instagram announcing the next product in her growing makeup empire, Kylie Cosmetics. And considering that she's normally so dedicated to all things matte, the new item is pretty surprising.

The video, titled "Glosses," is a three-minute scene that shows the 18-year-old social-media star applying lip gloss in a Rolls-Royce convertible (even though lip gloss and convertibles are normally a risky combo). For the majority of the video, Jenner sits in her car while a group of girls—all of them also wearing lip gloss—ambushes a man and steals his money.

Jenner does get up at one point to walk to the trunk of her car and put on a fur coat. Interestingly, she's wearing a snakeskin crop top and pants that look similar to the outfit Britney Spears wore on the cover of her 2000 album, Oops I Did It Again. She's also wearing a Louis Vuitton bandanna on her head—early 2000s vibes are all over the place in the video.

The video is an announcement for what we assume will be Kylie Lip Kit glosses, as in, shiny lip products that are a major departure from Jenner's signature aesthetic. And they're coming soon—tomorrow. So if you're a Kylie Lip Kit fan, stay glued to your computer tomorrow, because it'll most likely be another frenzy. We'll update with more information about the lip glosses as it comes. Check out Jenner's video below:

PSG defender David Luiz had admitted in an interview with the Journal du Dimanche that he is scared of ending up bald and commented on his rather unique hairstyle.

“I know I look crazy but I am not! It is just hair… Yes my father is bald. But I found a way to save my hair.”

The Brazilian has found a miracle cure that a man from Diadema, a town near Sao Paulo, has come up with:

“I met with a doctor in Brazil, who has developed a special treatment. It takes some cells from here (your hip) and then relocates then. I will do it. In ten years it will be the solution for people who have lost their hair. You should try it!”

Ligue 1 side Marseille will not stand in Steve Mandanda’s way if he decides that he would like to move to Aston Villa next month.

The player has the blessing of OM if he wants to leave because of the years of service that he has given to the club. It remains to be seen however whether or not Mandanda wants to take the risk to join the bottom Premier League side.

Let’s say you designed a mechanical assembly that requires some sort of mechanical sealing. Or you have a maintenance project that requires additional sealing to a new joint. Perhaps your assembly has a fluid reservoir, requires cooling fluid to pass through, or you’re joining two components together and need them to sit flush. To solve those problems, your first step is choosing the right type of mechanical seal. 

O-rings are reliable and affordable, which is why they’re a popular solution. But you need a good groove design for the O-ring to do its job properly. This guide will walk you through our best tips for designing O-ring grooves.

What is an O-Ring (Refresher)

An O-ring is a circular piece of elastomer material that’s used to form a mechanical seal resistant to pressure that seals off mating components. Some O-rings can withstand high pressures in the range of a few thousand PSI. The groove that the O-ring fits into is also known as the gland.

O-Rings vs Gaskets

While O-rings and gaskets may seem similar, they are actually different methods of mechanical sealing. An O-ring is a type of gasket, but not all gaskets are O-rings. Gaskets can be made of many materials, including metal, while O-rings are only made of elastic materials. O-rings are also specifically circular in shape, whereas gaskets take the form of many cross-sectional shapes. That’s why gaskets are used in applications where sealing is needed for complex mating surfaces. O-rings are more standard and are used for simpler mating conditions.

O-Ring Groove/Gland Shape

The most important consideration for gland design is that it allows for proper and complete compression between the groove and the surface mating to it. Otherwise, the shape of the groove itself is not important. The shape of the O-ring groove depends on the application for the O-ring and can range from triangular to rectangular to dovetail. 

Generally, it’s good to focus on a groove shape design that’s easy to machine without sharp edges that can cause O-rings to deteriorate. Specifically, every sharp corner needs an O-ring groove radius and all interfacing corners should be chamfered or rounded to limit damage to the O-ring while installing it. 

One of the most common O-ring groove shapes is a rectangular divet with rounded edges. This design allows for simple installation and uniform compression on all three sides of the O-ring that interface with the gland. See the example shape below:

O-Ring Groove Width

The first O-ring groove dimension we will cover is the O-ring groove width. The horizontal span of the groove should be sufficient to allow for full expansion of the O-ring within the groove. The horizontal span should only allow for a 5% expansion of the O-ring diameter. The OD (outside diameter) of the gland should be larger than the ID (inside diameter) of the O-ring so that the O-ring is always stretched when installed. 

For cases where an O-ring is not installed in a gland, the O-ring interface should be designed so that it doesn’t require more than a 100% stretch when an O-ring is installed. The ideal number for the O-ring stretch, when installed in a gland, is not greater than 5%. Minimizing the installation stretch is done by correctly specifying the gland ID to accommodate the O-ring diameter. You can use the following equation (O-ring groove width calculation starting point) to set the requirement: 

O-ring ID Stretch
 = 

GlandID – ORingID
ORingID

 *  100

Minimizing installation stretch can prevent an excessive buildup of stress in the material, reduce the cross-sectional area and reduce the % squeeze of the O-ring. Another important rule to follow is to keep the percentage reduction in the cross-sectional diameter to around 50% of the percentage diameter stretch. 

O-Ring Gland Width for Liquids versus Gases

In general, an O-ring gland for a liquid fluid should be larger than one used for gas — the liquid interfacing O-ring should be about 10-20% larger.

O-Ring Groove/Gland Volume

The best rule of thumb to follow for groove dimensions stems from specifying the correct amount of volumetric space for the O-ring material to fill the groove. This is necessary to ensure room for the O-ring’s thermal expansion (elastomers expand around 10 times more than metals), swelling due to soaking up fluids, and increasing width due to O-ring squeeze. The optimal ratio for O-ring gland volume is 15-25% empty space and 75-85% spaced filled by the O-ring material. The equations below calculate the gland fill percentage:

O – Ring Volume
 =  π * [

width

 ]²

Gland Fill %
 =

  * 100

Pro-tip: when designing any component, especially an O-ring groove, utilize technical data sheets, industry specifications and other resources for guidance on your specific groove interface and type. This article doesn’t cover all the scenarios, but there are many publications that do.

O-Ring Groove/Gland Depth

The depth of the O-ring groove depends upon the width of the O-ring and the amount of compression that is best for your application. A specific compression ratio should be maintained in order to provide sufficient sealing without compromising the integrity of the elastomer material. The compression ratio may be calculated with the following equation:

O – ring compression ratio
 = 

O – ringwidth – groove depth
O-ringwidth

  * 100

Utilize the following compression ratios as starting points: 

1. For rotary O-rings: a compression ratio of 0-10%
2. For reciprocating O-rings: a compression ratio of 10-20%
3. For a static male to female mating interface: a compression ratio of 18-25%
4. For a face seal: a compression ratio of 20-30%

Static vs Dynamic O-Ring Groove Design Considerations

Static O-ring applications — where the two components being sealed together don’t move — are the most common use for elastomer O-rings. Dynamic O-ring applications are utilized to seal two moving parts (with respect to each other). Both applications have their advantages and disadvantages. For example, wwelling is more likely to occur with a static O-ring, while material deterioration is more likely in a dynamic O-ring application. A static O-ring is an axial, radial, crush, or dovetail seal, where there’s pressure on the top and bottom of the O-ring. A dynamic O-ring forms a reciprocating, rotary, or oscillating seal that has alternating pressure on the O-ring in a back-and-forth manner. 

Radial squeeze applications are often recommended over axial squeeze applications for static seals because they depend on the groove dimensions to maintain sufficient sealing and they are easier to use when parts are being modified. For static sealing applications, a groove surface finish of 63 rms is recommended for the sides and 32 rms for the bottom of the gland. For dynamic O-ring applications, it is recommended that any component which interfaces with the O-ring have a surface finish of 16 rms or smoother.
