ocean exploration cables
In modern times, ocean exploration has become a worldwide hot technology. For this reason, multi-disciplinary ocean detection systems and detection technologies have been developed. All detection systems and detection technologies are inseparable from the carrier of power and signals-ocean detection cables.
Product Features
1. Comprehensive
For ocean exploration cables, it is often a cable that not only reliably provides power to ocean exploration equipment, but also accurately transmits the acousto-optic signals collected and processed by the detection instrument. Therefore, it is necessary to collect power lines, high and low frequency logic, analog and digital signals. The wire and the reinforcing element are integrated, and the photoelectric composite is made into a multi-wire group and a multi-functional comprehensive cable.
2. Electromagnetic compatibility
In order to eliminate the mutual interference of strong and weak current, high and low frequency signals, the structure of ocean exploration cables must be carefully designed, and the cores or groups of wires must be reasonably laid out. According to relevant standards, they must meet the requirements of electromagnetic compatibility.
3. Water tightness
Ocean exploration cables work in the ocean for a long time, and with different water depths, they bear different water pressures. Therefore, waterproofing is an important feature of cables. Not only must have horizontal and vertical watertightness, as well as their connectors or branch cables, they must be carefully sealed.
4. High strength and long length
Ocean exploration cables are in a special marine environment. They not only have to withstand the impact of waves and ocean currents, but also take on the task of retracting and towing the detection equipment. Most of them require high strength, especially high tensile strength and wear resistance.
5. Predetermined buoyancy
According to the different purposes used on the sea, underwater and seabed, ocean exploration cables are often manufactured into cables with predetermined buoyancy such as floating, waiting to float, and sinking to the bottom.
6. Resistant to chemical corrosion and biological attack
Ocean exploration cables must be resistant to salt spray, seawater corrosion, mold, rodent bites, and marine animals.

Environmentally friendly cables will be the trend of the cable industry
With the development of world economy and technology, the demand for wires and cables is increasing, and their performance requirements are also increasing. Under the new economic situation and technical conditions, the development of the global wire and cable industry is showing new trends. Environmentally friendly cables are gradually entering people's field of vision, and gradually replacing traditional cables to become the focus of global cable development. So, what is an environmentally friendly cable?
1. High flame retardancy
When a fire occurs, traditional cables are extremely easy to burn and release a large amount of harmful gases, while environmentally friendly cables are not only difficult to burn, but also prevent the spread of flames and the expansion of disasters after burning.
2. Halogen-free
Traditional cables generally use halogen-containing PVC to make insulating sheaths or cable filling materials, which are likely to produce carcinogenic "dioxin" substances when burned, while environmentally friendly cables use environmentally friendly insulating layers, sheaths and special oxygen barriers. The material is not only halogen-free, but also has good electrical and physical and mechanical properties.
3. Low toxin
The insulation and sheath of the environmental protection cable do not contain lead, cadmium and other heavy metals that are harmful to the human body. When the environmental protection cable is used and disposed of, it will not pollute the soil and water sources.
4. no corrosive gas
Environmentally friendly cables will not produce toxic gases such as HCL when they are produced, used and burned, and emit very little acid gas, which causes little damage to personnel, equipment and instruments, and shows environmental protection characteristics.
5. High light transmittance
The light transmittance of traditional cables is less than 20%, while the standard for environmental protection cable products is greater than 40%. Therefore, the smoke generated when the environmental protection cable is burned is extremely thin, which is more conducive to the evacuation of personnel and the conduct of fire fighting.
6, high protection
The environmental protection cable is not afraid of the erosion of ultraviolet rays, sand and rain, and can slow down the aging speed of the environmental protection cable to a certain extent and extend its service life

Basic characteristics and uses of reel cables
1. What is a reel cable? What is the purpose of the reel cable?
Drum cables are mostly used for flexible connection and control cables for hoisting lifts, stackers and reclaimers, dumpers, dumpers, mixers, port machinery drums, rock drilling rigs, roadheader drums, and electric scrapers At the same time, it can also be used as a winding and towing cable in the drag chain system. The cable reel is guided by the tow shaft or other similar devices for retracting movement. The reel cable can be installed in a dry or humid indoor or humid industrial environment, and can also be used for outdoor installation.
2. What are the basic characteristics of the reel cable?
1. Small bending radius: The working mode of the reel cable often needs to withstand long-term bending motion, so this kind of cable requires a small bending radius in use, which requires the cable material to have high flexibility and small outer diameter.
2. Excellent tensile and abrasion resistance: Since the working principle of the reel is rotation, winding, and pay-off, the reel itself is generally retracted and rewinded under constant tension, which has higher requirements for the tensile strength of the cable.
3. Rolling pressure resistance characteristics: most of the winding cables are single-track or multi-layer stacking, which puts forward higher requirements for the extrusion resistance of the reel cable itself.
4.Other characteristics of the reel cable: extremely strong mechanical load bearing capacity, oil and water resistance, UV resistance, general acid and alkali smoke prevention, anti-cracking, etc.
Spring Clamps
Spring clamps utilize spring tension to apply pressure to workpieces with one-handed operation. They are suitable for use in light assembly applications to hold material in place while gluing or fastening. The design features two handles joined by a spring, which operates in similar fashion to a clothespin. They can be set in place or adjusted by squeezing and releasing the handles, and they can be stored by clamping onto a clamp rack or shelf edge.Get more news about Spring Clamp Suppliers,you can vist our website!
Spring clamps each consist of two handles tensed by a spring to help keep pressure on the workpiece. Use a spring clamp when you need fast, easy opening and closing.
Needle-nose spring clamps each feature a long, tapered-nose design for hard-to-reach spaces. The ergonomic, 2-component handles can help provide comfort and firm grip. Soft-touch pads also offer a non-marring grip. Made of lightweight polyamide plastic. The ergonomic, 2-component handles are designed to provide antislip properties. Use a spring clamp when you need fast, easy opening and closing.
Deep-reach ratcheting spring clamps are ideal for double-sided step-over clamping, and are specially suited for T-profiles, such as square frames. They feature pivoting jaw pads, which are soft, slip-proof, and designed to help prevent marring. The clamps offer easy pressure application with a ratchet mechanism, and easy-to-control clamping force.
Double-jaw, variable spring clamps feature rapid-action sliding top and bottom jaws. They are made of lightweight, polyamide plastic, and engineered with ergonomic, 2-component, antislip handles.
Ideal for holding insulating mats in place, these spring clamps feature insulated solid plastic construction with an integrated spring, and are fiberglass-reinforced. They can help reduce risk of short circuits.
Retinoic acid in development: towards an integrated view
Retinoic acid (RA), the active form of vitamin A, is a small lipophilic molecule that acts as a signalling molecule in vertebrates by binding to nuclear receptors (heterodimers of RA receptors and retinoid X receptors; RAR–RXR) and regulating the transcriptional activity of various target genes.Get more news about retinoic acid,you can vist our website!
The distribution of RA is tightly controlled in embryonic tissues. Its synthesis from inactive precursors (retinol or beta-carotene) is mediated by retinaldehyde dehydrogenases 1 to 3 (RALDH1 to RALDH3), and a group of cytochrome P450s (the cytochrome P450 26 enzymes CYP26A1 to CYP26C1) trigger its tissue-specific catabolism. Both types of enzymes are often expressed according to mutually exclusive, complementary patterns.
Although there is clear evidence that RA acts as a short-range signal across tissue layers, its role as a long-range, concentration-dependent morphogen has long been debated. Recent work provided evidence for a robust RA gradient in the prospective hindbrain of the zebrafish embryo, shaped by the fibroblast growth factor (FGF)-dependent control of CYP26A1 activity.
Although the most anterior (prospective head) embryonic cells are initially protected from RA signalling by CYP26A1 and CYP26C1 activities, eventually RA is produced by RALDH2 and RALDH3 in the rostral forebrain neuroepithelium and surface ectoderm, and is necessary for proper growth and patterning of the embryonic forebrain and optic vesicle.
During extension of the body axis, a caudal pool of progenitor and/or stem cells is maintained by FGF8 signalling, and RA produced by RALDH2 in differentiating mesodermal tissues (including the somites) acts in an antagonist manner, promoting neurogenesis and regulating ventral patterning genes in the prospective spinal cord. RA is also necessary for 'buffering' left–right asymmetric embryonic signals, thus ensuring a symmetrical progression of mesodermal segmentation, that is, somitogenesis.
Various functions have been ascribed to RA with respect to heart development, recent work implicated it in the proper restriction of the cardiac progenitor cell pool in the early zebrafish embryo, and in the mouse in the formation and proper contribution of the 'second heart field' to the developing heart tube.
Cross-talk between RA and other embryonic signals are being unravelled. Contrasting with the functional antagonism between RA and FGF during caudal axis extension, during organ outgrowth RA was often found to have a positive effect on the induction (or the maintenance of appropriate levels) of FGF(s) involved in these processes. RA is also indispensable for cells to efficiently respond to the sonic hedgehog (SHH) signal, probably by controlling some downstream effectors of this pathway.
RA signalling has been detected in regions of the adult rodent brain containing neural stem cell niches, and some studies have correlated decreased RA levels with neurodegenerative diseases, such as amyotrophic lateral sclerosis, or Alzheimer disease. Retinoids are already used in therapy, and a better understanding of the effects of RA — in combination with other signalling factors — in stem cell populations might lead to novel therapeutic avenues.

Harley-Davidson creates new position dedicated to EVs
Automakers aren't the only ones looking to an era of electric vehicles this decade -- count motorcycles makers in, too. This past Wednesday, Harley-Davidson named its first Chief Electric Vehicle Officer, a newly created position to help implement the company's EV plans.To get more news about ebike, you can visit davincimotor.com official website.
Ryan Morrissey, previously of management consultancy Bain & Company, will take the new position having made a career out of working with OEMs to transition companies to EVs and more sustainable fleets. Harley-Davidson remains deep in a transitionary period after releasing its strategic turnaround plan called "The Hardwire." Through 2025, the motorcycle-maker won't only focus on profits, but will create a brand more focused on electric motorcycles.
This includes a division solely focused on zero-emissions bikes that will work to court what the company previously called "traditional nonriders." When Harley announced this new division, it certainly sounded like a lot of new research and development will happen there. Meanwhile, the company will open a new certified preowned program to bring more traditional riders into the brand.
Morrissey will clearly have an important role in the company moving forward. With the Livewire the brand's banner electric motorcycle right now, the new CEVO will hope he can guide Harley to a future full of the buzz the flagship bike created at launch.
When I recently spoke with Dennis Savic, founder of Savic Motorcycles, he explained to me that electric powertrains are still wildly expensive, even for large manufacturers because relatively few are being ordered/used, and the low volume leads to high prices. The good news is with so many companies popping up and technology rapidly improving, the prices for batteries and motors should start declining substantially not too far out from now.
As we discussed in our recent Auto Bahn story, emissions regulations are becoming tighter and tighter, and it’s becoming harder and harder for manufacturers to find ways of meeting these stringent standards without greatly sacrificing performance. The most current engines will keep officials content for the next half-decade or so (at best), it won’t be too long until firms start putting more and more of their eggs in the EV basket, and once these companies start figuring this out, they’ll start making moves sooner than later to prepare.
Zero Motorcycles sells up to 10,000 bikes per year and has a projected growth rate of 40% annually. That’s right on track with the in-depth analysis that lead to market research firm TechNavio’s projections that the electric moto sector is poised to grow by approximately 42% by the end of 2020. By 2025 the market is expected to have nearly doubled from where it stands today.
Electric Vehicle Group Partner to Deploy Electric Motorcycles Across Africa in 2022
Just as in most cities across Africa, motorcycle taxi drivers are in almost every corner of Nairobi. Josephat Mutiso is among the first drivers here to make the switch from fossil fuel to electric motorcycles, thanks to a partnership between Uber and Opibus.To get more news about electric motorcycle for sale, you can visit davincimotor.com official website.
“This is way efficient,” he said. “It is even way easier to ride than the other one. You see, this one you don’t have so ma"ny controls, you just have the throttle, no clutch. The only thing you are focusing on is just the front brake and the rear brake. That way it gives you even more control of the bike. And it is pretty light, it does not vibrate. So even clients like this one better.”
Motorcycle taxis have become increasingly common as public transportation in cities across Africa.
Joyce Msuya, the deputy executive director of UNEP, the U.N. Environmental Program, notes that motorcycle taxis have become increasingly common as public transportation in cities across Africa.
“The number of newly registered motorcycles, commonly used as taxis or boda boda, was estimated in 2018 at 1.5 million and will likely grow to five million by 2030,” she said. “Most are inefficient, poorly maintained and heavily polluting. UNEP’s study shows that boda boda drivers can more than double their income if they make the switch.”
In March, the U.N. Environment Program launched the first electric bikes project in Kenya, creating the momentum for Africa's shift to electric mobility. The partnership between Uber and Opibus seeks to accelerate that shift.
“We are just excited to get as many people exposed to the new technology that we built as possible so they know there is an option,” said Alex Pitkin, the chief technology officer at Opibus. “Uber provides, obviously, a lot of boda boda riders, that’s our target client. They often don’t know how beneficial electric motorcycles can be in terms of money-saving, safety, fuel savings, maintenance savings, you know that kind of thing. And longevity of the product as well, they don’t know that.”“Targeting Africa and African countries is also part of that movement and as Opibus, that is where we are targeting,” said Lucy Mugala, an engineer at Opibus. “We want all of us to move together. We all move towards a greener energy, a greener economy. And we can only do that if we all come together and empower and build capacity locally.”
