3 Ways to Lock CAD files and Protect Companies Drawings

AutoCAD files contains sensitive information that should be locked to some recipients or protected from editing. Often, companies need to share some CAD drawings with a team of professionals who work collaboratively to improve the designs, framework, or content. But while this is done, it’s important to protect these files and ensure that the ideas aren’t stolen or used without proper permission. In the following article you will find out the best 3 ways to lock CAD designs.To get more news about cad file download, you can visit shine news official website.

According to the U.S Department of Commerce, intellectual property theft is estimated at more than $250 billion and 750,000 jobs annually. The International Chamber of Commerce estimates the global fiscal loss is more than $600 billion per year.
Manufacturing companies across all sectors have a blueprint of operation that includes some of their most hidden secrets and system designs, representing the backbone of the company. To keep operations running smoothly and efficiently, these secrets must be protected from unauthorized hands and prying eyes.
What are CAD files, and how do they work?

Computer-aided design (CAD) files are typically used to create models, technical drawings, blueprints, or architecture plans via CAD software, and they may contain both 2D or 3D designs. Another term used to refer to the same thing is CADD (for Computer-Aided Design and Drafting).

The CAD files are an extremely valuable piece with extensive industrial applications, including sectors such as Civil Engineering, Architecture, Automotive, Shipbuilding, Aerospace, Fashion Design, Interior Design, Forensics, Prosthesis, etc.

In these industries, the CAD file helps companies safely store designs of their current technological tools and prototypes of new or future designs. When companies do their designing and prototyping, there’s a need to share the CAD files with various key persons in the operation channel for evaluation and possible improvements.

During file sharing, companies sometimes experience a breach in security, causing their drawings (designs or prototypes) to fall into the wrong hands. As a result, invaluable, revolutionary ideas may get stolen, causing unimaginable lo. Or operations ideas may leak into the hands of competitors and put the business at tremendous risk. Hence, the need to secure CAD files to protect companies’ intellectual property.
Theft Challenges Associated with the use of CAD files

A company’s intellectual property is one of the most sensitive business components. Every business’s uniqueness that makes it triumph over competitors is often buried digitally as intellectual property. Proper protection of the files carrying the intellectual property is essential to reduce business risks and avoid unbearable losses significantly.

Unfortunately, businesses are not always able to keep their files and intellectual property safe, especially in companies where there’s little awareness about the damages of a breach in cyber security.

According to research, the core intellectual property theft challenge companies experience with CAD files occurs via email attachments or web transfers. Other less prevalent sources of intellectual property theft include stolen USB devices and laptops.

While the sources mentioned above may be seen as external challenges, companies also face internal challenges stemming from their greatest assets – employees. Employees of a company may intentionally steal some sensitive intellectual property for personal reasons, putting the company at great financial risks.

Himiway Cobra Review 2022

After being teased for the latter half of 2021, we finally have a full review of the Himiway Cobra — the all-new full suspension electric fat bike from a company that built its reputation on long range, affordable and uber-powerful e-bikes.To get more news about himiway bike, you can visit magicyclebike.com official website.

It’s an e-bike I was admittedly skeptical of, for reasons I’ll get into more below, but despite my reservations, the Cobra has so far lived up to its hype.

In this Himiway Cobra review, we dive into the details of this full suspension electric fat bike and put it through the ringer in a gauntlet of tests and hard off-road riding to see how it stands up in the real world.
As you’d expect from an e-bike company known for power and range, the Cobra is built around a redesigned 750W rear hub motor and a 48V, 20Ah (960Wh) battery that’s fully integrated into the frame. But Himiway’s suspension design and a host of other upgrades, including hydraulic disk brakes and a torque sensor, are what really make this bike stand out.
As is usually the case with electric fat bikes like this one, the 750W rear hub motor is really the core of this bike.

As this is a new bike, the motor has fittingly gotten a redesign. This new iteration makes 86Nm of torque and is better at dissipating heat than the old motor. It’s fast, torquey and climbs exceedingly well.

Powering that motor is a 48V, 20Ah battery that’s removable and fully integrated into the frame. It’s large, and, in typical Himiway fashion, gives the bike a really solid range despite its inefficient fat tires and energy hungry motor.

The drivetrain on our review bike is Shimano Altus 7-speed with a Tourney shifter, the same setup that came on the old Cruiser.

Braking is handled by a set of Tektro hydraulic disk brakes with 180mm rotors front and rear, though Himiway’s website is more ambiguous about the type of brakes on the bike, indicating this part may get swapped out.

Suspension wise, the Himiway is a full suspension e-bike with a four bar linkage. I have to say I’m pleasantly surprised with how well this bike rides, which I have to be honest I did not expect to say in this review. My skepticism is rooted in the fact that this is Himiway’s first full suspension e-bike, they likely do not have much experience designing suspension systems and, to be totally frank, a full suspension e-bike at this price point is very hard to pull off.

See rear suspension is hard to pull off. It takes lots of engineering know-how, careful design and tactful use of materials to make a bike that feels laterally stiff and vertically plush. I’ve ridden plenty of affordable full suspension e-bikes that frankly weren’t worth the money, and another few that felt downright dangerous. But the Cobra is neither. I’m not sure if Himiway got lucky or really did put its money where its mouth is on this one, but the Cobra rides very nice.

Frame wise, the Cobra is a very large bike. Compared to other popular electric fat bikes such as the Aventon Aventure or Rad Power Bikes RadRover 6 Plus, the Cobra’s wheelbase is a full 4 inches to 6 inches longer. It’s also taller than either of those bikes, with a 32-inch standover height that’s 4 inches taller than the Aventure and 1.5 inches taller than the RadRover.

Study explores the effect of COVID-19 on platelet function

The coronavirus disease-19 (COVID-19) pandemic that emerged in Wuhan, China, in late December 2019 spread rapidly throughout the world and has caused over 6.5 million deaths. The disease is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a positive sense RNA virus that can lead to various clinical symptoms causing the hospitalization of many people with pneumonitis. Research has highlighted that COVID-19 patients have a high arterial and venous thrombosis rate involving pulmonary embolism, deep-vein thrombosis, ischemic stroke, and myocardial infarction. In addition, many postmortem examinations indicated the presence of microthrombi in the heart, lungs, brain, liver, and kidney of COVID-19 patients. This suggests that COVID-19 can cause systemic thrombosis, leading to multi-organ failure.To get more news about Профессиональный FАК, you can visit rusuntacmed.com.ru official website.
Previous studies have also observed that COVID-19 patients have a high level of serum coagulation markers such as D-dimer and fibrinogen. In addition, Thromboprophylaxis has been observed to improve outcomes in hospitalized COVID-19 patients. However, it did not significantly affect the mortality of patients with severe COVID-19. Therefore, thrombosis remains a prominent COVID-19 feature where high thrombin generation is not the only contributing factor.

Platelets essential for hemostasis can also lead to thrombosis due to inappropriate activation. Platelets can become hyperactive, leading to the increased secretion of dense alpha-granules, increased formation of platelet-leukocyte aggregates, and increased aggregation. Platelet transcriptome analysis has shown an overrepresentation of mitochondrial dysfunction and antigen presentation pathways in COVID-19 patients, leading to platelet hyperactivity. However, many studies also reported reduced or impaired platelet function in COVID-19 patients, suggesting that the platelet response is complex.
Although the pathogenesis of thrombosis in COVID-19 patients is not well understood, it comprises several hallmarks of thromboinflammation. SARS-CoV-2 can activate endothelial cells with the help of the angiotensin-converting enzyme 2 (ACE2) receptor, which leads to vascular dysfunction. Endothelium damage can activate the innate immune system through neutrophil recruitment, tissue factor (TF) expression, pro-inflammatory cytokines, and complement. This leads to higher expression and/or release of prothrombotic factors and upregulation of adhesion molecules which can activate platelets, causing thrombus formation, aggregation, and further activation of the innate immune system. Platelets can then increase the generation of thrombin through the expression of phosphatidyl serine and tissue factor (TF). This network of interactions between the innate immune system, platelets, coagulation, and damaged endothelium can contribute to thrombosis in COVID-19 patients.

A new study posted in the pre-print server bioRxiv* aimed to analyze the impact of COVID-19 on platelet proteome and relate the functional responses of platelets and the formation of platelet-neutrophil aggregate in hospitalized COVID-19 patients.

What are the seven essential features of a CAD software?

The CAD software must have all the necessary features to address your needs. To choose your computer-aided design (CAD) software, you need to take into account the current issues specific to your business! What are the challenges that professionals encounter for designing parts and machines?To get more news about 2d construction drawing software, you can visit shine news official website.

#1 A modern and ergonomic user interface
The first essential feature of the CAD software: its user interface. The way in which the tool is controlled and operated has a direct impact on the final productivity. The easier and faster the software is to use, the more productive the user becomes.
The commands must be designed according to modern conventions: copy and paste, drag & drop, contextual menus, etc. to allow the user to immediately adapt to the new tool.
Access to the commands should be easy, fast and intuitive, in order to optimize the user’s working time.
Choose a CAD software with a modern and ergonomic user interface: you reduce the learning curve and you can work faster.

#2 Associativity, a guarantee of reliability
Associativity automates the updating of one element with respect to another. The designer can therefore easily modify his construction history: the associated operations are automatically updated.

Illustrations:

Moving a screw automatically moves the holes.
Changing a chassis length automatically changes the positioning of the associated components.
With associativity, a key feature of good CAD software, you can drastically reduce the risk of errors or omissions when updating an element. And therefore, you can save time in the design process. So be sure to choose a tool that allows associative or parametric design.

#3 Choice in design methods
A good CAD software offers three design methods.

“Bottom-up” design: this is the simplest method which consists of first designing the parts individually, and then assembling them. This is the principle of LEGO®! The assembly is then a succession of predefined part positionings.
“Top-down” design: conversely, the designer starts from the constraint, then deduces the necessary assemblies and parts.
“In-place” design: a variation of top-down design where parts are designed in their assembly context. The designer then has the advantage of simplicity for the creation of connecting parts, in particular.
The relevance of which method to be used varies from one profession to another. A manufacturer of highly standardized products will favor the Bottom-up method, while a subcontractor who works “on the case” will favor the Top-down method, for example. In any case, the three methods are complementary. To take advantage of your CAD software, make sure that the tool offers these three powerful design methods: maximum flexibility in choice and the precious opportunity of complementary methods.

#4 Smart components
User productivity increases as good standard components are created. For this purpose, your CAD system must provide the appropriate features. Unique smart components, process management, installation wizards, etc. allow you to store user know-how. Ultimately, the design is accelerated: the productivity gain is obvious.

This Is the Right Amount to Spend on a Mountain-Bike Helmet

If you want to buy a trail mountain-bike helmet these days, you’re in luck. Half-shell helmets—the most common style for mountain biking and the only type we are dissecting here—are a popular category. There are about three dozen options from ten or so brands, spanning a massive price range, and all of them must meet the same Consumer Product Safety Commission impact-testing standards. That can make choosing a helmet quite difficult.To get more news about ebike helmet, you can visit magicyclebike.com official website.

There are several reasons to spend extra on a lid, starting with the fact that, well, it’s your head we’re talking about here. Aside from additional features (like improved ventilation) and better fit, pricier helmets have better design and construction that can—but won’t always—make them better performers in an actual crash. So if more-expensive helmets are lighter, better ventilated, and sometimes safer, how much should you spend?
Aside from cheapo lids at big-box stores, most mountain-bike helmets sold at independent bike shops start at $50 and go up to $300. For trail riding, our sweet spot—the point where you get the most performance for the dollar, and where additional gains per dollar spent start to tail off—is around $100 to $160. That’s a wide range, but as you’ll see, there’s a good reason for that.
How to Understand Safety Ratings
The primary job of a helmet is to protect you in a crash, right? Even though safety is the central goal, there’s not a lot of great information out there about how mountain-bike helmets stack up to one another. That’s partly due to how testing and certification work. The CPSC does not test helmets; instead, helmet manufacturers do their own testing (or pay a third-party lab to test them) and essentially self-certify. Also, CPSC standards are pass-fail, with no discussion of relative performance above the minimum thresholds, or compared to other models. For legal reasons, helmet makers almost never make safety claims or even talk about how far their helmets exceed testing standards, which means there are very few ways to really compare helmets for crash performance.

For higher-price adult helmets, the best source we’ve found for safety-performance testing is Virginia Tech. It is the only independent body in the U.S.A. publishing helmet-test results that reflect both linear and rotational impact forces (more on that soon) and assign overall numerical scores that allow limited comparison between models. There are other factors in buying a helmet, of course, but crash safety should be your main focus, and VT’s ratings offer the best method we’ve seen for comparing lids.
Features that Matter
Rotational-Energy Management
Every helmet listed below has a rotational-energy management system. This is a kind of “slip-plane” technology, typically a liner that sits close to your skull or between two layers of helmet foam. The most popular is from a third-party provider, MIPS (an acronym for “multidirectional impact protection system”), but some brands use proprietary systems (such as POC’s SPIN pads, or the honeycomb-like WaveCel technology exclusively licensed in Bontrager helmets).

Research suggests that traumatic brain injuries like concussions may result mostly from rotational forces that violently twist the brain inside the skull, rather than the linear impact force directed straight into whatever object you hit. Rotational-energy management systems work by letting the helmet slide and rotate slightly against your skull in the crucial milliseconds after impact, dissipating some of the forces that create that twisting or shearing stress on the brain.

These systems first came into existence about a decade ago. But no official certification standard (from either CPSC or similar protocols in other countries) measures rotational energy, so helmets are tested and certified only on how they handle conventional, linear impact forces. Still, we recommend that you buy a helmet with a rotational-energy management system. Thankfully, except for helmets purchased from mass-market retailers like department stores, it’s hard these days to find one without it.

Additional Safety Tech
Around $150, you’ll start to find helmets with roll-cage reinforcement: essentially a plastic or polycarbonate lattice inside the EPS foam that works a little like rebar reinforcement in concrete and helps hold the helmet together structurally in an impact. Some top-tier helmets also come with multidensity construction, which basically uses higher-density foam in some zones for better protection against high-energy impacts, with lower-density foam to help mitigate lesser crashes.

Fit, Comfort, and Ventilation
First, look at the fit system: typically a dial at the back that tightens the helmet around your occipital lobe. The best fit systems completely encircle the skull at the rim of the helmet, keeping your head centered; cheaper ones are anchored only halfway around and basically shove your forehead against the inside front. The cheap systems are less comfortable and may inhibit the function of rotational-energy management systems. (For folks with large heads and/or who wear larger-volume hairstyles, look for helmets whose size XL fits a head circumference greater than 60 centimeters, instead of going by the listed size.)

Are Bird Spikes or Netting Better for Bird Deterrents in Commercial Buildings

Birds can be a nuisance to building and facility managers. Their droppings can lead to extensive damage creating costly repairs and restorations to the building and plaza deck systems. How can this problem be solved? There are many options for bird repellents. A significant factor in the decision-making process is ensuring birds’ safety is front and center. To get more news about Bird Spikes, you can visit senpinghz.com official website.
Birds are more than just flying animals; they are vital to ecological well-being across the globe. Birds are some of nature’s most able cleaners. One vulture, for example, is responsible for over $10,000 worth of waste removal.

They are also massive contributors to pest control. Birds eat 400 to 500 million tons of insects every year. As such, they protect crops and help keep pest populations in check.”
Birds are vital to the environmental ecosystem, which must building owners and managers must consider when selecting the best bird repellent for their structures. Below are some of the core considerations when choosing which bird deterrent devices to use.
Bird spikes are commonly used bird repellents and see great success. They are used to deter birds from landing in certain areas, hanging around, and creating nests. Some pros to bird deterrent spikes are:

While there are many advantages to bird deterrent spikes, we must also address the disadvantages. Spikes are very effective at keeping the birds at bay; however, they can create other unsightly problems. Some spike bird deterrent cons are:

Netting is another option for bird repellents. It is an excellent option for bird proofing buildings as it prevents birds from accessing gardens, eaves, and canopies by creating a barrier. There are many pros to netting bird deterrents:

What Other Solutions Are Available if Neither Work?
The implementation of spikes and nettings are often effective but are sometimes not the optimal solution depending on the buildings’ needs. Multiple other solutions are available if spike deterrents and netting do not produce the wanted results. Some of these solutions are:

Visual Deterrents – Visual decoys are safe to keep birds away from buildings. Installation is easy, with the decoys hidden from the view of building occupants and visitors.
Audio Deterrents –  Audio devices are an effective method of bird repellents, and they do not cause harm to birds or impact the structural integrity of the building. They send out warning noises to other birds and can be effective from hundreds of feet away. They also work on all bird species.
Influencing Employee Behaviors – Encourage the proper disposal of trash and food waste. Birds are attracted to leftovers and garbage. Therefore routinely maintaining and cleaning gathering areas keeps this problem to a minimum.
Insect Control – Birds love bugs! The prevention of bugs naturally leads to the prevention of birds. Maintain a toxic-free insect control plan to aid in bird repellent.

Hovsco HovAlpha vs Himiway Cruiser - Ebike Comparison

We here at Hovsco believe the future of mobility is all about options. We take pride in providing high-quality e-bikes at an affordable price. The option may be how you get to work, exercise, adventure where you go, no matter your age or fitness level. By choosing Hovsco, you are choosing to use your hard-earned dollars in exchange for quality, affordability, and first-class customer service. There’s few things some riders have asked for more than a comparison of the Hovsco HovAlpha vs. Himiway Cruiser - two of the most popular and affordable fat-tire electric bikes. Let's have an overview about ebike parts comparison between these two ebikes.To get more news about himiway bike, you can visit magicyclebike.com official website.
HovAlpha is sure to be a powerful fat tire ebike that produce much 85 Newton meter torque, and it will help carry that power all the way to its top speed 28 mph. It’s also got a class leading range thanks to its huge 960Wh battery, which is a very cool feature. Its hydraulic disc brakes and more powerful battery 960Wh mean that HovAlpha has a better stopping power and can ride for a longer range.

A 750W geared hub motor is laced into the rear wheel of two ebikes. On the Himiway is one unbranded rear hub motors that appear very similar and on the Hovsco is a hub motor from popular manufacturer Sutto. Though similar on paper, these two motors put power to the ground in very different ways thanks to careful tuning.

The Hovsco HovAlpha also has an impressively large 48V, 20Ah (960Wh) battery that gives it a class-leading range, while the Himiway Cruiser’s 48V, 17.5Ah (840Wh) is much lower. The Hovsco and Himiway all have the typical five pedal assistance levels, which adjust power and the maximum motor assisted speed to give a rider added control over the bike’s motor. Details will be shown as below.

HovAlpha's motor has quite a more powerful motor and can travel further compared to Himiway Cruiser's. This extra capacity is made possible by using the same battery cells that Tesla is using in their latest electric vehicles. From the ground up, these cells are designed to provide a more powerful experience in a smaller space.
The simplest and most accurate way to put it is that our motors are equal. Powerful, brushless, and located in the same place on the ebike.
The Himiway Cruiser comes with a 5-speed pedal assist enabled via a cadence sensor. But HovAlpha comes with a better 85 Newton Meter torque sensor which adjusts output power optimally to achieve a highly-satisfying riding experience.
The two models have the same top speeds and pedal assist levels, giving riders a versatile riding experience and allowing them to fine-tune their pedal assist level as their desire.
The Hovsco HovAlpha sports some pretty impressive specs, with a high-powered 750-watt rear hub motor that peaks at 1032 watts. The Hovsco HovAlpha has a 20Ah battery versus the 17.5 Ah battery found on the Himiway Cruiser. The HovAlpha has a nicely integrated battery design with the battery placed directly into the frame whereas the Himiway Cruiser is using an externally mounted battery.

And though it comes out of the box hitting speeds of 20 miles per hour, it can be modified to hit 28 mph. Priced at a competitive $1,899, it’s a strong entry into the fat ebike realm, and in a slick-looking package with quality components.

EUNORAU launches an all-terrain powerful fat-tire eBike

The American electric mobility company EUNORAU has launched a new monster model called DEFENDER S. It is an all-terrain powerful fat tire ebike, which is designed with dual-battery and dual-motor configurations.To get more news about electric bikes for adults, you can visit magicyclebike.com official website.

It is basically an “all-wheel drive” electric mountain bike. The EUNORAU e-bike is in fact powered by two electric motors made by the Chinese Bafang, both inserted, respectively, in the hub of the front wheel and in that of the rear wheel, although the classic frame of an e-bike provides for the insertion of the engine in special housing in the central compartment. Each of the motors has an output of 750 watts (48 volts) for a total of 1,500 watts in the case of the DEFENDER S Pro version.
The standard DEFENDER S comes with a single 750-W Bafang rear-hub motor and is likely the most versatile of the two versions available. The maximum speed it can reach is 35 mph (56 km/h).

The Lithium-Ion Samsung is provided in the option units from 672 Wh or 816 Wh. But those who wish can mount a second 816 Wh battery on the down tube, thus reaching a total of 1,632 Wh. The dual configuration promises up to 80 miles (128 km) per charge. Both batteries can be removed for charging, which takes 4-6 hours. The gearbox is a 9-speed Shimano Alivia.
The frame is made of Alloy 6061 aluminum alloy. The fork is from RST; it is a low-end model GUIDE with a 75 mm stroke. The damper is again from DNM Suspension, has a 165 mm stroke.

EUNORAU DEFENDER S and DEFENDER S Pro are available for delivery worldwide. The basic version with a single rear hub motor starts at $1,799 through an Indiegogo campaign, while the dual-motor Pro monster is listed at $1,999.
the premier online marketplace that continues to serve as the one-stop-shop for eBikes and bicyclists – has designed yet another eBike: The Denago Fat Tire eBike. this new all-terrain eBike will be initially offered in a step-thru model with two sizes to accommodate a wide range of riders.

On road or off-road, the four-inch-wide tires and front suspension fork allow for a comfortable ride – providing the utmost comfort while also granting riders the ability for four season exploration.

Not to be overlooked, the Fat Tire eBike is a powerful and versatile model equipped with a 750 Watt rear hub motor and forty eight volt 19.2 Ah / 921.6 Wh lithium-ion battery – Denago's largest capacity battery to date. The new battery features LG 21700 cells, which pack 40% more energy into the same compact space. The latest Denago eBike includes fenders, kickstand, integrated brake lights and a front headlight. With speeds up to 28 MPH on pedal assist and 20 MPH on throttle, the dynamic Class III eBike recharges in just 3-4 hours, providing riders more time to get out and explore.

"If you are looking to do more with your eBike, the Denago Fat Tire is a great option," explains David Duecker, "It makes it easy to traverse trails, campgrounds or RV parks, as well as cruise the city streets in comfort." He continues, "A fat tire eBike is one of the most versatile eBikes around and is guaranteed to make you want to explore new places."

With the holiday season rapidly approaching, at $1999.00, the Denago Fat Tire Step-Thru eBike is one of the best valued fat tire eBikes equipped with a torque sensor available today. The new model is available at independent bicycle dealers throughout the United States and through Denago's online retail partner

Seal Ductwork with Mastic and Mesh Tape

Leaks in the heating and cooling duct systems can be frustrating for homeowners who were hoping to have a tight, energy-efficient home. If the ductwork for the home's environmental conditioning system is installed improperly, or if aftermarket products such as whole-home air filters have been improperly installed, it can greatly reduce energy efficiency. Leaky ductwork is a serious defect that can increase the homeowner's energy costs and reduce long-term customer satisfaction.To get more news about Mastic Tape, you can visit senpinghz.com official website.

When the home's duct system isn't properly sealed, carbon monoxide and other toxic fumes that are byproducts of natural gas appliances can build up in the home and create an unhealthy and potentially lethal living environment. Another problem occurs when noxious fumes from common household items, such as cleaners, solvents, fertilizers and paints, are drawn into the home's return system through poorly sealed joints. Once these smelly and potentially dangerous fumes are drawn into the duct system, they can be circulated and recirculated through the home.
While most builders understand the importance of properly installing the duct system, the actual work is done by the HVAC contractor. To make sure that all ducts are properly sealed and that the home will perform at optimum efficiency, it's up to the builder to closely and critically inspect the duct installation. The best practice for ensuring energy efficiency is to apply UL 181-rated mastic and mesh tape to each and every joint in the ductwork.

Mastic is a gummy substance that has been used since the Roman era, but only recently was modified for residential construction purposes. There are several kinds of mastic available today, both water-based and solvent-based. Although each works well, water-based mastics tend to release fewer fumes, which can be helpful when working in tightly confined spaces. Look for mastics with a low flame spread and smoke-developed rating. For most jobs, builders will want to make sure that the mastic they use is UL 181-rated. UL 181-rated mastic is proven to be more flexible, adhere better to ducts, and last longer than other mastics.
Make sure the joint area has been wiped clean to remove particles and dust before applying mastic. If the joint isn't clean, the mastic won't create a tight seal.
Apply enough mastic to form a continuous coating on the surface of the duct. Use a brush, trowel, gloved hand or caulking gun to apply the mastic. A cheap paintbrush can work well, but many people find it faster and easier to simply use their hands to scoop out mastic. If the trade contractor prefers this method, make sure that they're wearing heavy rubber gloves that won't tear if pressed against a sharp edge of sheet metal duct.
Work the mastic into the joint or crack and press lightly to get an even coating. There should be at least a 1/2-inch overlap around any joint, crack, or hole in the duct.
Use a mesh tape to reinforce the mastic coating on areas where there's a gap of 1/4 inch or more. This is especially important if the area being sealed is a joint that will be under stress. It's always important to make sure the tape used for sealing the joints is designed specifically for mastic being applied.
Duct tape shouldn't be used to seal ducts. Over time, the conventional tape will dry, crack and eventually give way to costly air leaks. Because many of the joints in a home's HVAC system are inaccessible after the insulation and drywall are installed, repairing a leaky duct system can be difficult and expensive.

By making sure that the HVAC contractor properly applies mastic and UL-181 rated tape to every joint in the home's duct system, builders can greatly improve the energy efficiency of the home and help ensure the future health and safety of their customers.

Everyone needs a good bike helmet and they are always to be found during Black Friday deals season.

If that's still too hard to filter through, we've also included the standout helmet, that we found faultless, so if you're unsure what to buy, buy that.

It's worth bearing in mind that we've listed the weight of the helmet size that was reviewed, so just do a quick double check of the listed helmet size as it will vary between sizes making the weights not always a comparable factor. If you buy one road bike helmet, buy this. Here at Cycling Weekly we get to test lots of different helmets across lots of different categories, but if we had to pick just one, this would be our absolute favourite road bike helmet.

An absolute favourite road bike helmet for us is the Giro Aether MIPS. On test we called it a game-changer of a road bike helmet due to its unrivalled all-around performance.

During the review period, we found this helmet to be exceptional in its ventilation ability and at the cutting edge for safety features. While there are slightly lighter helmets, such as the Kask Protone helmet, it was still an impressively low weight at just 269g (for a size small).

The Aether features the gold standard MIPS Spherical technology, which sits between the two shells to make the added safety feature a really comfortable option. Teaming this with the added reinforcement construction gives the rider lots of reassurance on how safe and strong this helmet really is.
We highly rated the Lazer Blade helmet when we saw the non-MIPS version, so this new safety feature update is music to our ears.

While it does push the price up a little, this is still a really great price for head protection with what is considered the gold standard of safety features.

Good enough looks wise to compete with helmets much higher up the food chain, as well as providing great ventilation means that this is a great road bike helmet for anyone wanting a more affordable all rounder. Testing it back to back with the more expensive Kask  Mojito helmet, we found very little to choose between them.
Weighing just an incredibly 220g/ 7.7oz for a size medium, the Kask Protone helmet offers, according to the brand, one of the lowest drag and fastest heat dissipation options on the market. 

We found the Protone to be one of the most comfortable helmets we'd ever tested, and indeed one of the lightest, beating the Giro Synthe by 20g (0.7oz).
