Pascal 2021 HW is suited for applications where water vapor is expected such as low temperature sterilization and drying. The two-stage rotary vane pump has a gas-ballast system that allows the pumping of large volumes of vapor without condensation inside the pump. This prevents accumulation of fluid that would adversely affect the service life of the pump and the pump oil. It utilizes special materials to resist aggressive chemicals such as hydrogen peroxide. The pump is ready to deliver vapor in just a few minutes due to a customized temperature-management system. It has a safety device that impedes the water from entering into functional sections of the pump if the steam capacity is inadvertently exceeded.
HOW DOES A SHRINKING MACHINE WORK?
When it comes to the shipping and manufacturing industry, one thing we know for certain is that businesses want their products to be shipped securely and in excellent condition. Our shrink wraps are puncture and tear resistant, extremely durable, and FDA approved for direct contact with food. They can be used on any manual, semi-automatic, or fully automatic L-bar system.Get more news about Auto Shrink Wrap Machine,you can vist our website!
Shrink wrapping is typically done using one of several methods - manually, automatically, or a combination of both. If you’re shipping smaller items with less volume, a shrink wrap heating gun may work fine. However, for larger products and larger quantities, a shrink wrap machine is far more efficient.
A shrink wrap machine is a machine used in heat shrink packaging. The machine generally includes a sealer and heat source to apply heat to the shrink wrap, however there are several types. Some of the types include heat sealers, shrink wrapping combination systems, shrink tunnels and fully automatic shrink wrap machines.
Most shrink wrap machines use some form of heat sealer to seal the open ends of the shrink wrap. However, the overall function work in different ways.
Heat sealer (I-Bar): An I-Bar sealer works by using a single sealing bar to seal and cut the shrink film in one motion to enclose the package or product. This manual sealer usually works best with lower output processing.
Heat sealer (L-Bar): L-Bar sealers work at higher speeds and have two sealing bars that are positioned in the shape of an L (hence the name). As this is also a manual sealer, it is also best for lower output operations.
Shrink tunnels: These are great for medium to high-speed, large output operations. They are typically paired with an L-Bar sealer to amp up the efficiency of the machine. They also come in various sizes and dimensions and are suitable for persons wrapping 150 or more products per day.
Shrink wrapping combination systems: As the name suggests, this machine is a combination of two in one: The L-bar sealer and shrink tunnels. This system usually comes with different functions, two of which are a magnetic hold and discharge conveyor option.
The magnetic hold function keeps the L bar sealer in a sealing position until the seal is complete. This allows users to position the next product while the seal finishes, hence improving efficiency.
The discharge conveyor transports products into the shrink tunnel. This saves time users from having to touch the product after the initial seal.
Fully automatic shrink wrap machines/Conveyors: As you can imagine, these machines are best for high output, high speed operations. The fully automatic shrink wrap machines have powered conveyors to feed products into the shrink wrap machine continually. Conveyors are used at the exit of a shrink wrap tunnel.
The Impact of Two Different Cold-Extruded Feeds and Feeding Regimens on Zebrafish Survival
Zebrafish (Danio rerio) is one of the top model organisms used in biomedical research. Therefore, it is fundamental that zebrafish facilities continuously improve husbandry methods to provide fish with the best physiological and welfare conditions that suit each experimental purpose. Nutrition is a husbandry aspect that needs further optimization, as it greatly affects growth, reproduction, health and behaviour. Here, we have compared the impact of different feeding regimens on zebrafish survival, growth and reproductive performance. Mutant and wild-type zebrafish were raised using several combinations of two cold-extruded processed feeds—Skretting GemmaMicro and Sparos Zebrafeed—and one live feed (rotifers). Zebrafeed outperformed GemmaMicro in terms of survival rate, and embryo viability was also higher when the spawners were fed with Zebrafeed either from larval stage or upon sexual maturation. In contrast, GemmaMicro favoured growth, both in size and weight. The use of rotifers until 60 days post-fertilization improved survival of fish co-fed with GemmaMicro, while delaying their growth. Zebrafeed® performance was not affected by co-feeding rotifers. Overall, we showed that different nutritional formulas affect physiological parameters, allowing for the establishment of feeding protocols adapted to the objectives of each facility. At the same time, we validated Skretting®GemmaMicro and Sparos®Zebrafeed as two commercially available feeds that are well suited for zebrafish nutrition in a laboratory environment.Get more news about Micro Precision Cold Extrusion Part Exporter,you can vist our website!
Research in different models has historically promoted the importance of nutrition in outcomes related to development, health, disease and responses to toxic compounds in food and the environment [1,2,3]. Yet, there is a striking absence of literature showing the role of nutrition as an important regulator of health and disease in zebrafish. If nutrition is to be accepted as a critical part of health management, it is imperative to consider the typical end goal of fish production in a research setting: to provide fish that are clinically healthy and representative of animals exhibiting normal physiology [4]. Although the known nutritional requirements of other cyprinid fish can be an acceptable approach to zebrafish requirements [5,6], this does not take into account some particularities of the species, such as high growth rate, infinite growth, continuous egg production after maturation. The feeds and feeding regimens implemented by research laboratories for rearing zebrafish are varied [7]. In some cases, feeds and feeding regimens are implemented without a formal evaluation [8]. While the world aquaculture relies on fish meal (FM) as the main protein source in aquafeeds [9], research over the last decade has resulted in a significant decrease in the portion of FM in fish feeds, and there are species-specific limits in the FM replacement rate by, for example, soybean (SBM), above which irreversible damages occur affecting fish growth performance and welfare [10,11]. Therefore, meeting the specific nutritional requirements of zebrafish will potentiate growth and promote an optimal physiological status, minimizing undesirable effects and allowing for more consistent results [12]. The use of purified diets with defined ingredients facilitates the determination of the precise nutritional requirements, promoting optimal performance in fish stocks [13].
Having alternative suppliers of live and processed feeds, which results in fish with high, optimized and standardized growth, survival and breeding rates, is a management requisite for zebrafish facilities. Comparing different feeds tested in previous studies [14,24] that have demonstrated good impacts on growth and reproductive performance is the first step towards achieving this. This study aimed to understand which combination of commercial processed feeds, Skretting®GemmaMicro® and/or Sparos®Zebrafeed®, complemented with Type “L” saltwater live rotifers Brachionus plicatilis, is more suitable for improved survival, growth and reproductive performance.
In this study, we used two strains of zebrafish that are widely used in biomedical research: wild-type AB and non-pigmented Nacre mutant (mitfa −/−). Embryos were obtained by overnight crossing 8–10 females with 4–6 males of each strain stock in 1.7 L sloping breeding tanks (Tecniplast®). The housing and husbandry of all animals were performed as published [25], and dietary adaptations were in accordance with the specifications of the present study (Table 1). Briefly, all embryos were collected, placed in 90 mm diameter petri dishes with standard embryo medium [26] and kept at 28 °C in an incubator with a photoperiod of 14 h:10 h/light:dark up to 5 days post-fertilization (dpf). Early 6 dpf larvae were transferred to 3.5 L tanks at a density of 35 fish/tank, each containing 400 mL of fish water and 100 mL of type “L” saltwater rotifers (Brachionus plicatilis) solution (0.5 mL of RG Complete™, ~800–900 rotifers/mL, conductivity ~3 ppt). At 8 dpf, water flow was started through the 3.5 L tanks, and larvae began to be fed according to their experimental group (Table 1).
How Long Will My New Athletic Running Track Last
I’m often asked what the lifespan of a running track is? Most people who ask this question are really only considering the synthetic surface, but there are other more important key components to consider when estimating the maximum running track longevity and overlooking them will severely compromise your investment. Here are 4 variables that will greatly affect the how long question:Get more news about high quality running track,you can vist our website!
1. Meets all 4 Critical Components = Will last 20‐30 years.
If the substructure, that is the drainage, stone‐base and laser‐controlled asphalt, is properly designed and constructed and a high quality sealed polyurethane synthetic surface is properly installed, an athletic running track can last for 20 to 30 years with proper maintenance and resurfacing.
2. Quality Surface + Poor Substructure = FAILURE
If the substructure has been designed and/or constructed poorly, no matter how high quality the surface you choose or how well it is installed, the athletic running track will fail prematurely‐ possibly in the first few years, resulting in cracking, settling, bubbling, or worse.
3. Quality Substructure + Poor Surface = FAILURE
If the running track surface has been poorly installed but the substructure has been designed and constructed well, the track surface will fail prematurely and possibly as soon as the first few years.
4. The key point fundamental to maximizing the running track longevity is ensuring that the substructure be properly designed and constructed and a high‐end, sealed polyurethane system must be installed properly.
5. Other variables that come into play are climate, maintenance practices of the school, UV degradation, freeze‐thaw cycles, and poor quality construction all of which will greatly reduce the longevity of a running track to a few years before problems arise. If well built, running track longevity could be 2‐3 decades with timely, proper maintenance, and resurfacing.
If the infrastructure is built well, the track surface chosen will have a large impact on how long that component lasts. An unsophisticated system but well‐constructed latex track versus a well‐constructed high‐end polyurethane track could have a running track longevity differential of 10‐20 years with maintenance and resurfacing. It is truly imperative to find an experienced athletic running track designer who writes a strong spec that will be followed and installed by an experienced and specialized athletic facility builder that offers a quality warranty for maximum running track longevity. This could mean the difference of your track lasting from 1 year to 20+ years.
Why are JST connectors so scarce all the sudden?
Do you mean vernacular term JST as in any little plastic PCB connector including all kinds of gray market fake clones or genuine JST components from JST the company?Get more news about jst connector production,you can vist our website!
Its a single supplier. JST is single company in Japan. I'm sure they're busy doing "stuff" and having fun trying to ship things.
Its like trying to buy Nichicon capacitors. There is one company in Japan making Nichicon capacitors. If they're busy, well, they're busy and you wait. There are zillions of "e-waste" reprocessors in China whom will desolder larger electrolytics from old PCBs, peel the plastic shrink, and apply a new shrink with all manner of trademarked names and temperature ratings to random e-waste pulls, including falsely labeled Nichicon. Those are the only two suppliers of Nichicon caps and if they're both busy or sold out you're outta luck.
Now if you're willing to change your BoM or if your safety regulator permits it and your company purchasing dept has a relationship with competitors and no single-sourcing agreement for better prices, you can use fantastic products from Chemi-con or Vishay or tens of serious competitors and hundreds of not-so-serious competitors.
Because you're doing stuff with JST XH I "know" you're doing something with modern RC vehicle batteries. I'm old, we played with RC cars in the 80s using Molex connectors and had the same problem as now, Molex is a single company and if they couldn't ship we didn't get connectors and that was the end of the discussion.
Full size car batteries are not licensed single source technology. Then again a lead post of a given diameter isn't very high tech. AFAIK there are no rechargeable battery pack connectors that are unlicensed at this time. FOSS type projects to issue a standard connector might arise, someday. Could implement 18650 individual cells and holders, those are unlicensed and not trademarked AFAIK but I have not verified that.
BTW JST connectors are extremely complicated not just wire and plastic. The posts are made with a cheap copper alloy, then plated with thick copper and plated again with tin, and the solder tabs are made the same way. I guess the PITA of a stage of pure copper plating is cheaper than paying for pure copper for the entire post. Copper is expen$ive. The plastic is a weird polyamide nylon-alike with some secret sauce flame retardant mix in that supposedly doesn't corrode copper or tin, so the connectors don't burn terribly well. Nylon usually doesn't burn until it melts anyway. Very hand wavy polycarb would melt or be tiresome to deal with at reflow solder temps, nylon is only like fifty degrees tougher but that's tough enough to make it easy to reflow nylon connectors. Or more specifically it'll keep its shape deep into the decimal places after reflow. They used to make polycarb capacitors from like 1960 to 2010 but they gave up, I guess impossible to hot air reflow them I don't know for sure.
SWEDISH MATCH SNUS AND NICOTINE POUCH COMPANY BOUGHT
Phillip Morris International (PMI) had bought Swedish Match, a company known for its snus and tobacco pouches. Swedish Match is an interesting tobacco company - it is a tobacco company that doesn’t produce cigarettes. Instead, Swedish Match focuses on snus and nicotine pouches. But what are snus, and how can they affect vaping in the long run? Let’s start with the basics.Get more news about hot sale snus oem,you can vist our website!
WHAT IS A SNUS? WHAT IS SNUS USED FOR?
Snus is a kind of tobacco product. They are a form of tobacco from Sweden, and are pronounced like moose but with an s instead of an m. Snus are basically small teabags filled with tobacco. To use a snus, it is placed in the mouth between the gums and the lips.
One of the reasons snus are popular is because their immediate side effects are generally less offputting than cigarettes or chewing tobacco. Snus generally do not create as much odor or spit as chewing tobacco or traditional cigarettes. Some snus are even flavored with menthol, spices, or fruit flavors.
What are nicotine pouches?
Nicotine pouches are very similar to snus, and can be seen as a specific type of snus. Instead of being filled with tobacco leaves, nicotine pouches are filled with a non-tobacco substance, and nicotine is added to the pouches to give them a similar effect as snus. The most well known nicotine pouch is Zyn, which is also manufactured and produced by Swedish Match.
WHY IS SNUS IMPORTANT?
What’s notable about snus is that they are a product that has already gone through the Pre-Market Tobacco Application (PMTA) process, and the FDA has given them the status of a Modified Risk Tobacco Product (MRTP). This means Swedish Match’s snus are legal to sell in the U.S. market and can be advertised as a safer alternative to smoking. Though snus were not well known at the time their application was approved, they could become more popular if Phillip Morris decides to invest in developing them. Swedish match even has a notable fruity flavored snus approved through a Marketing Equivalence Order - Timber Wolf Pouches Peach was approved in December 2019, and is a snus flavored like peaches.
Though Zyn doesn’t seem to have a marketing approval order at the moment, an application has likely been submitted as the FDA has not sent out any warnings regarding Zyn. Additionally, nicotine pouches using synthetic nicotine would not have needed to submit a PMTA until the law changed so that synthetic nicotine was also included in the definition of a tobacco product. If the PMTA was submitted much later than most, it is possibly still in the PMTA process.
Casting Process Produces Parts with Thin Walls
A western New York aluminum casting company is using a technique more advanced than traditional sand casting to produce parts with smoother surface finishes, tighter tolerances, and thinner, vertical walls. The company is TPi Arcade, Inc., and its technique is called V-Process casting.Get more news about Sand Casting Parts,you can vist our website!
TPi Arcade (www.tpicast.com) operates a 55,000-square-foot foundry that makes parts for the medical, robotics, marine, semiconductor, power electronics, and electric vehicle markets. The company also manufactures parts used in aerospace, defense, heavy equipment, transportation, and instrumentation applications. Its castings range from a few ounces to 150 pounds.
“It’s technically a sand casting, but more innovative,” said Erik Depczynski, a mechanical engineer and technical sales manager at TPi Arcade, describing the firm’s V-Process casting technique in a telephone interview. “It’s a refinement, an improvement. V-Process offers unique advantages, such as highly cosmetic finishes, thin walls, tooling flexibility, the ability to cast vertical walls, and most importantly, speed to market.”
The company employs about 65 people, including five full-time, degreed engineers who assist customers with design for manufacturability. It offers rapid prototyping, CAD/CAM design assistance, a first article often within two to three weeks, and the first production run two weeks after approval, Depczynski said.
“Our engineers are also dedicated program managers that provide a single point of contact for our customers, from their design conception to delivery of first production run,” Depczynski said in an emailed response.
TPi Arcade provides turnkey parts manufacturing services, from casting and machining to chemical conversions, painting, powder coating, and assembly. Parts produced by the manufacturer include robotic linkages; medical cart bases; wake tower structures; heat exchangers; and housings for inverters and other electronics. The company has also manufactured instrument bases, brackets, weldment conversions, and housings for defense communication equipment.
The firm is ITAR compliant and AS9100:2016 certified for the manufacturing of aluminum V-Process castings. The scope of its certification includes melting, molding, cleaning, and heat treatment.
V-Process Basics
The “V” in V-Process stands for vacuum. V-Process sand requires no binder, resulting in a smoother and denser metal. Instead, it vacuum packs the sand between sheets of thin plastic film, according to the firm’s website. The mold’s top half—the cope—and bottom half—the drag—are draped with the plastic film, which keeps sand away from the pattern in the center being molded. That smooths the part finish. The plastic and the vacuum hold the sand in place, producing an improved finish and allowing for thinner, vertical walls.
The V-Process is similar to permanent mold or die casting, but its costs and volumes are more similar to traditional sand casting. It differs from traditional sand casting for several reasons.
The process is reported to offer surface finishes superior to those of traditional sand casting by using a fine sand without a binder. For consumer-facing products, a smooth finish is more appealing than a rough surface. The V-Process uses finer sand, which leads to a finer part finish. The surface finish is between 125 RMS and 150 RMS, whereas traditional sand-casting results in a surface finish between 250 and 500 RMS.The RMS scale represents surface roughness by measuring the root mean square between a surface’s peaks and its valleys. A lower number means the difference between valleys and peaks is smaller, so the part is smoother. A rough surface may require post-processing to smooth it out, thereby adding to cost.
A customer not familiar with V-Process might assume a minimum wall thickness is 0.25-inch. But the V-Process allows TPi Arcade to form vertical (no draft) walls as thin as 0.125-inch, an advantage that saves material, space, and post-processing costs. The narrowest walls are about 0.25-inch thick in sand casting, but they must be cast wider at the base, forming a taper or draft. “Without a taper, there is no release. It’s usually about two degrees per inch,” Depczynski said.
The draft adds extra metal, reducing the size of the interior. If a customer needs that space inside a box, traditional sand casting requires post-processing to machine the draft away. But the V-Process walls eliminate that step—thereby saving cost—because they are vertical and don’t require machining to remove draft.
4 MAJOR CHALLENGES OF FINANCIAL TRANSLATION AND HOW TO OVERCOME THEM
The process of globalization is strongly developed, not only leading to the focus on cultural and social networks but also on economic exchanges and foreign markets. Besides language barriers, you have to deal with the financial rules and regulations of the countries you are approaching which are likely to have some major differences from those of your country. That’s when financial translation services come in handy.Get more news about financial translation agency,you can vist our website!
In this blog, we will give you an overview of financial translation, from its definition to common types of financial documents that need translating. More importantly, we will discuss 4 huge challenges of translation for financial content and give you some tips to overcome them.Translating financial content is considered one of the most challenging types of translation as the financial translation has its own set of concepts and vocabulary that necessitates specialized knowledge within economics and finance.
Together with an increase in the demands for translating financial papers, there are some big challenges that almost all companies have to deal with when working on a translation project. Below are 4 common challenges and useful tips for you to overcome them.
#1. Punctuation Rules
Punctuation rules play an all-important role in translation. A financial translation requires utmost accuracy as it contains many numbers. Just a slight mistake in a number can result in a loss of hundreds or even millions of dollars.
#2. Financial Translation Terminology
Getting the terminology correct is one of the most frequent financial translation issues encountered by linguists. This profession uses highly specific and detailed terminology, making it difficult for individuals without prior knowledge or expertise to grasp.
#3. Time Constraints
Fast turnaround times have never been more crucial in business than they are now. A higher likelihood of success comes from being more agile than your rivals. Financial statements follow a similar pattern. The timeline is limited.
The majority of businesses will issue their annual reports and financial statements at the same time since both have set publication dates. This entails a tremendous amount of precise and urgent labor for translation agencies. Translators frequently collaborate with a financial reviewer or an auditor to expedite the process.
#4. Confidentiality
Financial documents and reports require high confidentiality since they contain a lot of important information about a company, business, or even a nation. That’s why confidentiality is really necessary. When a financial translation is exposed, the company or business will fall into a dangerous situation, even bankruptcy.
