The Riviera design group utilise 3D computer-aided design to bring their designs to life



With a proud boatbuilding heritage spanning over 42 years, Riviera is renowned for using the finest methods to handcraft motor yachts that are internationally acclaimed for their build materials, structural strength, and luxury finishes. Powerful 3D motor yacht design technology is harnessed by the Riviera design group to allow them to bring to life their very latest creations.To get more news about cad in design, you can visit shine news official website.

Driven by a passionate and experienced team, 3D computer-aided design (CAD) and computer-aided manufacturing (CAM) offers a comprehensive, world class process for yacht design and building at Riviera.
3D CAD Modelling
Utilising 3D modelling software, solids and surfaces are added to 2D vectors such as points, lines and arcs to create the motor yacht design. Integrated into the process is naval architecture software, which provides tools for hull modelling, structural analysis, comprehensive stability and resistance predictions. The primary advantages of using 3D CAD in boatbuilding are the ease of design, speed of construction and the ability to reuse information.
The 3D CAD assembly
Traditional 2D CAD systems focused on hull formation, naval architecture calculations and structural schematics – essentially this was old-style drafting on a computer. However, leading 3D CAD software is utilised by the Riviera design team to create the thousands of different components that make up a motor yacht and, critically, it enables a ‘whole of vessel’ blueprint that illustrates how the parts come together – from the hull to the timber joinery of interior cabinetry.

The first step in creating a motor yacht is the hull design. Its parameters are set by considering its length, beam, deadrise (the angle between a horizontal plane and the hull surface), performance, seakeeping and stability. A hull must maximise strength and space while minimising weight. Once established, engineers can determine the yacht’s fuel position for appropriate weight distribution.
There is a balance between creating a hull that’s fit for purpose while offering enhanced accommodation and living spaces. Hull structure, head space, usability and aesthetic appeal all must be considered. Once this is established, the team can work through the general assembly: how the cabins and living areas come together. A grid and floor structure are designed, and the necessary and appropriate core materials, composites and laminates are selected.

One of the great benefits of working with 3D CAD is that multiple trades can work on a design at the same time: exterior designers, interior designers (joinery trade), naval architects, mechanical engineers, electrical engineers, and production engineers.
CAM: Five-Axis Computerised Numerical Control (CNC) Machining
The deployment of Five–Axis CNC machining provides exacting detail that is precise to the millimetre of CAD specifications. It is employed to create the production model, or plug, from which the moulds are built for the hull, deck, flybridge and hardtops.

The Five-Axis refers to the various degrees of freedom that are possible in the computer-controlled equipment used to cut, shape and create different parts and prototypes. These degrees of freedom are fundamental to motor yacht building as straight lines are rare as boats primarily feature curves.

Thousands of individual pieces of timber and composites are also designed in 3D CAD and manufactured with CNC machines. Other components such as stainless-steel fittings are manufactured in-house from drawings produced from 3D CAD.

Panerai Radiomir –  Iconic watch since 1936


Whether stainless steel, ceramics or rose gold: At CHRONEXT, you can find a wide range of the Panerai Radiomir at fair prices – many of them available for immediate delivery. Discover the watch of interest to collectors and experience the Italian sense for iconic design.To get more news about panerai luminor replica, you can visit paneraireplica.co official website.

Panerai can look back on a company history that stands out in the watchmaking industry. The company was originally founded in 1860 but did not produce timepieces for commercial sale until 1993. The few watch models produced up until that point were exclusively intended for professional use in the navy. The majority of the timepieces, including the Radiomir, were catered towards the Italian Marina Militare.
In 1936, Officine Panerai created a prototype timepiece for the Royal Italian Navy, which was distinguished thanks to its screw-down crown and case back, ensuring reliable water resistance. Three years following, the prototype went into production. The dial of the watch impressed with optimal legibility even under unfavourable conditions, thanks to its hands and indices that were coated with a luminous zinc sulphate and radium bromide mesothorium. The founder’s grandson under the name of Guido Panerai Radiomir patented the luminous chemical mixture, but he, unfortunately, did not know that the radium substance was highly radioactive. Although Radiomir timepieces that were created in early stages are still currently somewhat dangerous due to their radioactive substance, they are limited edition watches that are highly sought out by the vintage watch industry.

The designs of the current Radiomir collection however are highly reminiscent of the original military timepieces while they are produced with a completely safe Superluminova material.
Radiomir
In 1993, Panerai timepiece became accessible to the public and the company presented models like the Luminor and Mare Nostrum to enthusiastic watch experts and connoisseurs. It was only in 1997 that the new Radiomir generation was introduced to the world. The Radiomir was limited to 60 pieces in platinum. Much like the original model from the 1930s, the Radiomir PAM 210 was equipped with a case that measured over 47-millimeters in diameter. In the subsequent years, further Radiomir models were launched, including some variants with smaller case diameters.

The unmistakable shape and bold crown of the Radiomir aroused widespread interest among worldwide watch collectors and enthusiasts. This comes as no surprise since, next to the Luminor, the Radiomir is one of the most sought out models from Officine Panerai. The Radiomir is available in different versions, although all of the timepieces that constitute the collection remain true to the shape of the original watch. Furthermore, the timepieces are fitted with in-house manufacture movements. Popular models from the line include the Radiomir PAM 210 or the simple Radiomir 8 Days PAM 346.

The Radiomir Black Seal line holds a special place among the Radiomir collection as it celebrates the original 1930s model. The names of the timepieces allude to the manned torpedoes that were used by the Italian Navy. The first model of the line, the PAM 183, was launched in 2004. Today, the popular collection constitutes many models, such as the PAM 388, the PAM 287, and the PAM 292.
A tribute to the past
The 47-millimeter 1940 Radiomir lives up to its name. After all, the model pays homage to the equally large diving watches from the 1940s. The main difference between the Radiomir 1940 and the other Radiomir timepieces from the collection lies in the lugs of the watch. The Radiomir 1940 is comprised of a watch case and lugs that are carved out of a single block of metal. Therefore, the Radiomir 1940 differs from other Radiomir models because its lugs are attached directly to the steel case, just like they were in the original models. Other Radiomir models are fitted with lugs that are welded to the case. The dial of the Radiomir 1940 is characterised by typical Panerai clarity. The small seconds that is located at the 9 o’clock position is another characteristic feature.

The first Radiomir 1940 line appeared in 2012 and quickly advanced to the ranking of a modern classic. Panerai has continued to expand the Radiomir 1940 collection to include more variants and now features smaller case diameters. A prime example is the 42-millimeter Radiomir 1940 PAM 512, which is a classic model that pairs perfectly with both everyday outings as well as elegant occasions and special evenings.

China's economy has turned rotten and its reopening boom is a 'charade



Confidence that China's economy can rebound from Covid restrictions is untethered to economic realities, Rockefeller International chair Ruchir Sharma wrote in the Financial Times.To get more latest china business news, you can visit shine news official website.

"Something is rotten in the Chinese economy, but don't expect Wall Street analysts to tell you about it," he said, listing several indicators that point to underlying weakness.

For example, Wall Street's assumption of 5% GDP growth would suggest corporate revenue growth of 8%, but it rose by 1.5% in the first quarter.

In fact, corporate revenue is slower than GDP in 20 of the country's 28 sectors, and the MSCI China stock index down 15% from a January peak, he added.

Imports — a strong indicator of consumer demand — dropped 8% in April, and credit growth last month was half as fast as forecasts. In addition, youth unemployment hit 20% and is rising.

"These facts point to the source of the rot," said Sharma.

Since 2008, China's economic model has been driven by government stimulus and rising debt, especially in property markets, he explained.

But now Chinese debt service already accounts for a third of disposable income, excess savings in China are equal to 3% of GDP compared to 10% in the US, and China's growth potential is only half of its 5% target due to a shrinking population.

"A growth model dependent on stimulus and debt was always going to be unsustainable, and now it has run out of steam," Sharma added.

Instead of becoming the main drivers of growth, the property market has fallen into a debt crisis. The increasing inability to finance the debt has reverberated across markets, with industrial sectors slowing at a quicker rate than consumer-related firms.

Despite this, Western observers continue to hold out that China's rebound narrative is still within reach, which Sharma finds detrimental to eager investors.

"'Boomy' chatter has contributed to investors' loss of hundreds of billions of dollars in China in just the past four months," he said. "Further, global growth may prove weaker than expected in 2023, since the hope is that a US downturn will be countered by the China reopening boom, which may never come. It is time to expose this charade before the fallout gets worse."

BD Advances Prefilled Flush Syringe with Integrated 'Scrub-the-Hub' Innovation


BD (Becton, Dickinson and Company) (NYSE: BDX), a leading global medical technology company, announced expanded customer availability of an all-in-one prefilled flush syringe with an integrated disinfection unit designed to reinforce compliance to infection prevention guidelines and simplify nursing workflow.Get more news about Advanced Syringe Auto Feeder,you can vist our website!
IV lines are an integral part of the care process for many patients with up to 90 percent of hospitalized patients receiving an IV.1 Yet the improper care and maintenance of these devices is one of the leading sources of catheter-related bloodstream infections (CRBSIs).2 While the clinical practice guidelines are clear on the importance of disinfecting a needle-free connector before every access — a process commonly called "scrub the hub" — compliance has been reported to be as low as 10 percent.

BD PosiFlush™ SafeScrub is a prefilled saline flush syringe that features an active disinfection unit built right into the tip cap of the syringe that is demonstrated via in vitro testing to significantly reduce microbial growth associated with CRBSIs.3 By integrating the scrubbing device into the syringe unit, the device is designed to more easily enable compliance to "scrub the hub" guidelines and reduce touch contamination. This design simplifies steps and streamlines workflow for nurses, while providing a tool to help protect patients.

Health care facilities are continuing to feel the burden from the pandemic with high rates of nursing turnover and shortages," said Dr. Nathan Gilmore, chief of service critical care at Hoag Hospital in California. "At the same time, hospitals worldwide are still seeing increased rates of preventable catheter-related infections, which can be both dangerous to patients and costly for hospitals. It's not easy to be a frontline caregiver right now. Nurses need efficient and effective solutions to help them advance IV catheter care while improving the safety of their patients."

As the global leader in vascular access solutions, BD is committed to advancing the standard of care for IV therapy for patients and health care providers. BD PosiFlush™ SafeScrub received clearance and was introduced to select customers in October 2022. The innovation is part of the company's vascular access management portfolio and further drives the BD "One-Stick Hospital Stay" vision by helping to reduce complications, including infections, and extend catheter dwell times through proper IV care and maintenance, which may result in improved clinical outcomes. Optimal maintenance of the IV line helps to reduce the risk of complications so it does not have to be replaced and lasts throughout a patient's hospital stay. This is the third pillar of the "one-stick stay" vision that also includes first, reducing unnecessary needlesticks by choosing the right vascular access device and placing it successfully the first time and, second, using one IV line as a single access point for required therapies and blood draws.
"We continue to hear the need from health care professionals for new solutions that help make medication delivery safer and simpler," said Eric Borin, worldwide president for Medication Delivery Solutions at BD. "Our latest innovation in scrub and flush technology is designed to support nurses by simplifying workflow and advancing evidence-based best practices in catheter care so they can continue to focus their time where it matters most – on patient care."

High pressure applications


Every compressed air application needs certain pressure for normal operation and for easier classification of the compressors and the equipment for air treatment some non-written rules regarding pressure ranges were determined.Get more news about high and low pressure components wholesaler,you can vist our website!

During compression concentration of solid particles increases significantly. For example, if we have a constant volume and if we increase the pressure from ambient to 7 bar overpressure the concentration of solid particles will increase 8 times. This is already a huge increase of solid particles but still almost nothing compared to concentration increase to 400bar overpressure where solid particle concentration is 401 times higher than the concentration at the ambient pressure.
We already mentioned that compression will increase concentration of solid particles but it will not affect maximum water content which is determined just by the air temperature. If we compress the air with 100 % relative humidity at 35 °C to 7 barg approximatelly 0,3 l of water will be condensed during filling of 1 m3 reservoar at constant temperature. Amount of condensed water will increase to 15.6 l when filling the same reservoar to 400 bar at constant temperature. From this we see, that at high pressure applications significantly more water is condensed and needs to be removed from the system.

But if we have 100 % relative humidity at 1 bar overpressure and if we reduce the pressure to ambient the same amount of water molecules will be distributed across 2 times bigger volume which will result in 50 % relative humidity and accordingly lower dew point.
 Operation of cyclonic separator is based on centrifugal force which causes aerosols to collide into the housing wall and water droplets then drip to the bottom of the housing where the condensate can be drained. Essential part of the water separator is a plate on the bottom side, that prevents already separated condensate to re-enter the air stream in the system. The place beneath the plate where is no turbulence is known as “dead zone” or “quiet zone”. Properly dimensioned cyclone separator can easily achieve 98 % efficiency with less than 10 mbar of pressure drop and is one of the most efficient products for removal of already liquefied water from the system.

What are the top five performance needs for HVAC/harsh environment connectors?



Amid a plethora of performance requirements for connectors used in heating ventilation and air conditioning (HVAC) systems and other harsh environments, five stand out as especially important — ingress protection against dust and moisture (IP rating), extreme temperature operation, balancing mating/unmating forces and contact resistance, retention force and locking mechanisms for robust operation, and safety.Get more news about Harsh Environment Connector,you can vist our website!

IP ratings
The IP classification system is defined in IEC 60529. Connectors in HVAC and harsh environments often need a high IP rating. IP ratings consist of two digits. The first digit indicates the level of dust and object protection on a scale from 0 to 6. The second relates to the level of protection against liquids (Figure 1). For example, a connector with an IP68 rating is dust tight and can withstand powerful water jets directed at it.
When specifying an IP rating, it’s necessary to consider how much exposure the connector will have to debris, tools, even fingers, and dust including very fine powdery particles, dirt, or sand, and whether the anticipated exposure is intermittent or continuous. Exposure to water is a major consideration for systems like HVAC that may be outdoors and exposed to the elements. IP ratings extend to systems that may be submerged.

Some HVAC systems and equipment used in harsh environments may require sealed connectors with an IP68 rating. That can include wire-to-wire connectors and other interconnect styles (Figure 2). If connectors are not properly sealed, dust, water, and other materials can get inside the connector, and potentially inside the equipment, disrupt signals, corrode contacts, and cause physical damage to other system elements.
Connectors are thermally rugged components. But they have temperature limits. Many connectors are rated for operation up to 85 C°. In the case of HVAC and other harsh environments like industrial and automotive systems, that’s often not sufficient. An HVAC condenser system, for example, may be located on the sunny side of a building in a hot climate where temperatures may be excessive. In addition, the motor drive and other electronics in the compressor will dissipate heat, pushing the temperature higher. And the contacts in power connectors carrying high currents can experience some level of self-heating.

Connectors designed for use in HVAC and harsh environments are often rated for 105 C° or higher. It can also be important to make sure the connector can function reliably in unusually cold weather. That same compressor that experiences summer heat, may be exposed to sub-zero temperatures in the winter.
Contact resistance can vary depending on the normal force between the pin and socket. A high contact normal force results in the greatest surface area contact between the pin and socket and lower contact resistance. Designs with low normal forces can result in inefficient signal or power transfer. Connectors are designed to balance the highest practical normal force with a reasonable level of required mating force. Mating and unmating involve different combinations of forces, as a result, mating requires greater force than unmating. During mating, the contacts are first spread open as the pins and sockets come together. The force required during this phase is a combination of the insertion (spreading) force and friction (Figure 3). During unmating, the contacts naturally return to the original shape without requiring any force and the only force experienced is friction.

Retention force is not the same as unmating force. Unmating refers to disconnecting a connector. There are two definitions of retention force. One definition relates to how firmly the pins are held in the connector body. Adequate contact retention force is needed to absorb contact mating forces and resist forces resulting from normal use of the connector. Retention force is measured in Newtons, and the correct retention force reduces the potential for contact damage. EIA-364 MIL-DTL-38999 Method 4.6.32 defines the axial force necessary to displace a contact from the proper location when inserted into a connector. Manual and automated tools are available for measuring retention force (Figure 4).
