![]() The deployment of Lusankya was controversial within the New Republic military. The counter-offensive was spearheaded by the Executor-class Lusankya, commanded by General Wedge Antilles, and Rogue Squadron. ![]() It saw the capture of Orinda as the first phase of a renewed Imperial push to the Core. The New Republic was unconvinced by Pellaeon's pledge to respect the new border, and were panicked by the reappearance of the Star Dreadnoughts as tools of war. Pellaeon sincerely added that if the New Republic respected the claim, the Empire would refrain from further offensive action. Once entrenched at Lonnaw, Pellaeon sent terms to Ord Mantell: the New Republic was told that Orinda had been reclaimed to secure the Empire's borders and for its cultural significance to the Empire. At the same time, there was an attempt to covertly subjugate Dathomir and its witches. Pellaeon and Phennir struck Coreward along the Entralla Route, capturing Orinda and six other systems within a few weeks before digging in at Lonnaw. Main articles: Raid on Orinda and Battle of Lonnaw Megador was deployed to Agamar to guard the Empire's eastern flank., while Reaper embarked the elite 181st Imperial Fighter Group under General Turr Phennir at Borosk. The campaign would rely upon the New Republic remaining ignorant of the existence of Dominion and Megador until the crucial moment. Symbolically, the Mid Rim trade world held value as one of the New Order's greatest successes outside the Core, and was also the former seat of the Imperial Ruling Council Pellaeon also felt that the demonstration of strength displayed in retaking it would give the New Republic pause without provoking an overwhelming response. With his new authority and a newly-unified Empire, Pellaeon resolved to wage a decisive offensive to restore Imperial morale, and demonstrate to the New Republic that the Empire was still a power to be reckoned with. The three Super Star Destroyers gave Pellaeon enormous leverage, and he was made Supreme Commander of the Remnant's forces by the Council of Moffs. Reaper would serve as the Admiral's flagship in the coming campaign. When Pellaeon absorbed the Pentastar Alignment, these two warships were joined by the Executor-class Reaper. Among the bounty were the Super Star Destroyers Dominion and Megador, both of which had been abandoned intact at the Deep 3 shipyard. Before abandoning the Deep Core and retreating to the Pentastar Alignment, Pellaeon salvaged cached equipment located by analyzing the records he had inherited. Following the failed offensive against the New Republic in early 12 ABY and the subsequent retirement of Admiral Daala, Vice Admiral Gilad Pellaeon assumed command of Imperial forces in the Deep Core. ![]() It should be addressed as soon as possible to prevent total engine failure. This is a symptom that may be present at the start of the problem or as the problem progresses. It may also cause the engine to backfire. This will cause a rough running engine condition. When this happens, ignition timing will be off because the spark plugs are not being fired in time, or in order. If the timing gears are going bad or failing, the valves may not open correctly to allow air and fuel into the cylinders or close correctly to release exhaust fumes from the cylinders. The timing gears are an important component of engine and ignition timing. Engine runs rough or backfiresĪn engine only runs smoothly when all of its components are in working order. ![]() Allowing time to progress without addressing noises heard from the engine compartment could cause damage to other engine components. ![]() This is a symptom that may be present at the start of the problem or as the problem progresses and should not be ignored. Those attributed to timing gear failure could be caused by the timing gear itself, the timing chain rubbing or hitting something it shouldn’t, or the timing chain guides being broken or worn out. There are several things that can cause noises from the engine compartment. Rattling noises from the engine compartment may be an indication that the timing gears are going bad or failing. Rattling noises from the engine compartment It is also possible that timing gears that are going bad or failing may cause the engine to run rough, backfire and/or not run at all. If valve timing and ignition timing are not accurate, noises from the engine compartment may be noticeable. If the timing gears are going bad or failing and the timing chains are unable to be turned by the camshaft and crankshaft, valve timing and ignition timing will be off. If the exhaust valves are not opening and closing properly, exhaust gases will be trapped inside the cylinder. If the intake valves are not opening and closing properly, the correct air/fuel mixture will be unable to enter and remain inside the cylinders. As the piston moves upward inside the exhaust the exhaust valves open to expel exhaust valves from the cylinders. As the piston moves downward inside the cylinder, the intake valves open to allow fuel and air into the cylinder. These components are important for proper engine timing. The camshaft turns to allow intake and exhaust valves on the cylinders to open and close. The crankshaft turns to move pistons up and down inside the cylinders. The purpose of timing gears is to allow the camshaft and crankshaft to turn the timing chain. Lots of regular faces and friendly people. Community: We have a very involved group of members and staff.

Audio sounded excellent, whether I was connected via Bluetooth or the 2.4 GHz dongle, thanks largely to the headset's "TriForce Bio-Cellulose 50mm drivers." In terms of general fidelity and crispness, I didn't notice a difference between the Barracuda Pro and my Sennheiser Momentum 3 headphones.īass on the Razer headset was punchy without being overpowering, which I appreciated while listening to Rhys Fulber's Collapsing Empires album for the first time. I tested Razer's headset with my phone, my main gaming/work PC, and my Nintendo Switch. Audio Performance of the Razer Barracuda Pro Bravo, Razer.Īside from the carrying case, you get two USB cables, one USB-A to USB-C male for charging and the other USB-A to USB-C female to use for plugging the small USB-C dongle into systems with minimal Type-C ports, or those that only have Type-C ports at the back. This is the best bundled carrying solution I've seen from any headset or headphones at anything approaching this price range. And there's even an internal compartment for charging cables and the USB-C dongle. ![]() This makes it far easier to travel with the headset. I really like that the Razer Barracuda Pro ships with a rigid carrying case, rather than just a bag (like the $100 pricier SteelSeries Arctis Nova Pro). But there's no proximity sensor that pauses audio when you remove the headset (granted, this feature can be tricky to get right). Note that the headset turns itself off after 15 mins without sound running through it (adjustable up to 60 mins in software). The volume wheel is next up (which is plastic and feels a little cheap for a $250 headset), followed by a mic mute button near the top where the band attaches to the cup. While all this functionality packed into a single button is appreciated, and at least some of it is intuitive, I would have preferred to just have a couple more buttons included for media control. Double pressing the power button rejects or swaps calls, and skips to the next track. The power button behind that does quite a lot, acting as a pause button for media if you short press it (plus accepting or ending a call) and a pairing button if you hold it after turning the headset on. The left can has the USB-C charging port at the bottom. The company also rates the headset at a solid 40 hours of battery life. ![]() It also sounds great (thanks to 50mm "bio-cellulose" drivers), was quite comfortable for hours of use in our testing, and includes a nice rigid carrying case for taking the Pro on the go. ![]() ![]() And bucking the trend for a company often known for expensive, RGB-lit hardware, the Barracuda Pro is both understated in its black plastic shell and one of the least expensive options we've tested in this gaming headset meets lifestyle audio realm, at $249.99. Razer's Barracuda Pro is the latest offering in this realm of do-it-all audio devices aiming for a spot on our best gaming headsets list. It seems many headset makers have realized this lately, with Corsair, Epos, and most recently SteelSeries releasing wireless headsets that can connect to your phone and a PC or console at the same time, while offering up active noise canceling to help shut out the horrors of the world outside your head. If you're going to spend hundreds on a gaming headset, there's a good chance you might want to use it with more than one device, and for things non-gaming related like work meetings, long-distance travel and your daily commute. ![]() ![]() Like the Burj Khalifa, the precise height of Dubai Creek Tower will only be revealed during the opening. Either way, it will be the world’s tallest man-made structure, if ever completed. Since it is more of a spire than a building, some estimates put its final height at 4,413 feet (1,345 meters). However, the official final height has not been announced. According to the initial rumors, the Dubai Creek Tower will be a 3,045-foot-tall spire with around 200 floors. The construction of the tower is anticipated to span many years. Nearly 15,000 workers were employed on it at one time. It’s expected that the harbor project’s 2.3 mi 2 (6 km 2) of land will make it the city’s cultural and historical epicenter while being three times bigger than Downtown Dubai, the city’s tourism hub. This neighborhood is located close to Ras Al Khor National Wildlife Sanctuary. The Dubai Creek Tower will serve as the centerpiece of Dubai’s new metropolitan area, Dubai Creek Harbor. Location of the Tower Dubai Creek Harbor and Dubai Creek Tower.Ībout 5 miles (8 km) to the east of the Burj Khalifa is where you’ll find the location of the Dubai Creek Tower. ![]() The encircling viewing spaces and gardens planned for the building’s higher levels are meant to evoke the grandeur of another old marvel, the Hanging Gardens of Babylon, which was also built in an arid setting. And it happens that the Burj Khalifa designers were also influenced by the same flower. When designing the Dubai Creek Tower, architect Santiago Calatrava also took inspiration from the lily, a flower that thrives in dry areas. These exterior tension wires and the structural base of the Dubai Creek Tower are planned to be illuminated in a dynamic fashion. Steel wires connected to a concrete shaft create a sleek and elegant framework for this ultra-tall skyscraper. In the end, they appear to be inspired most by the Eiffel and some by the Gardens of Babylon. The tower’s designers looked to Islamic architecture’s classic feature, the minaret, as well as the Hanging Gardens of Babylon and Western landmarks like the Eiffel Tower for inspiration. The city of Dubai’s aesthetics and architectural enhancement have been the primary focus of the Dubai Creek Tower. But will it ever be completed? Dubai Creek Tower’s Design And the tower is expected to cost around $1 billion to build. The Spanish architect Santiago Calatrava conceived the plan for the Dubai Creek Tower. The operator of the Dubai Creek Tower and its environs, Emaar Properties, briefly halted construction in 2020 due to COVID-19. As of the year 2023, construction has only reached the basement level. The Dubai Creek Tower aims to surpass the Burj Khalifa in Dubai, currently the highest structure in the world, by 328 feet (100 m), if not more. The original deadline for completion was 2020, when the World Expo in Dubai would start. In Dubai, a 200-story skyscraper known as the Dubai Creek Tower is being built to a height of at least 3,045 feet (928 meters). Additionally, the tower will feature a mix of facilities such as hotels, restaurants, shops, and residences, along with viewing platforms and sky gardens as part of its expansion plan. The tower’s developer, Mohamed Alabbar, believes that the construction of such a magnificent structure is an excellent way to boost the price of real estate in the area, citing a comparison with Paris’ main attraction, the Eiffel Tower, where apartments with a view of the tower are up to 30 percent more expensive. The main purpose of building the Dubai Creek Tower is to increase the value of nearby real estate. ![]() If you do not have an enable as part of your Laser you could route the power supply that powers the laser through the Estop relay but be aware that when using this method that when the Estop is restored the power will be reconnected and the Laser will turn back on. If your laser has an enable input you can connect an Estop relay to your Laser to disable it in an emergency. The Laser module board would commonly be found mounted on top of the Laser itself with or without a fan as shown below.Įnsure that the wires carrying power from the laser power supply are correctly sized for the required current. The image below show several examples of typical driver boards. It is common for a Laser unit to have only 3 terminals Power, GND and PWM and this is a common configuration with most lasers. Here it has been put into clear heatshrink. It is a good idea to insulate any resistor mounted in this manner to avoid accidental contacts.The resistor can be installed at the Laser or directly on MASSO as shown below.If you are unsure if your Laser has a pull down resistor there is no disadvantage in adding the resistor.This is needed for correct PWM operation.The 5.6K resistor installed between the PWM output and MASSO GND is important and must be installed on all Lasers that do not include a built in pull down resistor.Information on how the Laser used in testing can be found here: Opt Lasers MASSO uses TTL only and controls the power of the laser using PWM. please consult the user manual that came with your Laser to establish the correct connection. The connections shown below are for demonstration purposes only. If you are unsure if your Laser has a pull down resistor built in there is no disadvantage in adding the resistor. This is needed for correct PWM operation. The 5.6K resistor installed between the PWM output and MASSO GND is important and must be installed on all Lasers that do not include a built in pull down resistor. How you connect your Laser will depend on what type of Laser you have and it's interface. When the Laser Tool 111 is selected the display automatically changes to show Laser related information.To change between 2D View and Depth Map view press the button at the top right of the display area.For a Grayscale engraving to be able to be viewed as Grayscale, the Gcode file must include T111 M06 at the start of the file or the Depth Map view will be blank.Offsets are only needed when switching between the Laser and other tools and only if they are part of the same Gcode file. It would not be uncommon to leave the Z offset set to 0 and to manually zero the Laser when doing the job. The Z offset will be determined by the focus point of your Laser offset to the Z zero point of your Spindle tool. This can be measured zeroing the DRO's, making a spot with the Laser and then jog the Main spindle over to the center of the spot and reading off the X Y Y coordinates on the DRO's. X,Y & Z offset is the distance from the Main spindle or other Main tool if using Waterjet or Plasma.Since power is controlled by turning the Laser on and off very rapidly, if you have a low PWM frequency and move quickly you could get a line that has areas where the laser was on or off - A frequency of 10Khz should be a good balance. It is recommended that you select a value of 10Khz though this will depend on the power of your Laser and the maximum feed rate you will be moving at. ![]() Go to the Multi-Head setting page and select Laser Engraving/Cutting.An output can be assigned for Air assist is required.An output can be assigned to move the Laser into position when Laser is selected.No other output can be used for this function as it includes special hardware to output a PWM signal.Configure MASSO output 11 for the LASER Engraving/Cutting output as shown.Safety glasses suitable for the laser you are using.Move to X0 Y0 at a feed rate of 600 with Laser intensity of 0% PWM (off).Move to X100 Y100 at a feed rate of 600 with Laser intensity of 35% PWM.Move to X100 Y0 at a feed rate of 600 with Laser intensity of 35% PWM. ![]() The S command must be included with a G1 and is synchronized with motion.

In 1997 Francois Gauthier-Lafaye wrote a plea to the journal Nature, advocating that mining of the Bangombé uranium be stopped. In the late 1990s, there was danger that the last natural nuclear reactor at Bangombé would be mined as well. Only a limited number of specimens remained that were made available for study. An additional seventeenth natural nuclear reactor was also discovered at Bangombé, located about 30km to the south-east of Oklo.īy the time the significance of the discovery was realised by the scientific community, the sixteen natural nuclear reactors at Oklo had been destroyed, completely mined out for their rich uranium ore. Further exploration discovered sixteen natural nuclear reactors in uranium mines at Oklo. It was considered very important to the officials to account for this ‘missing’ uranium-235. However, there were high concentrations of elements like cesium, curium, americium and even plutonium to be found. The uranium ore was anomalously depleted in uranium-235, containing only 0.717%. During a routine isotopic measurement of uranium ore from Gabon, it was noticed that the uranium ore did not have a uranium-235 content of 0.720% as most other known deposits. The French had been mining uranium in Gabon, at Oklo, for several years to utilise in their nuclear power plants. The probability of natural fission was theorised by Paul Kuroda in a 1956 paper, but not proven until seventeen natural fission sites were discovered in Gabon in 1972 and became commonly known as the ‘Gabon Reactors’. The first man-made nuclear fission plants were only developed in the 1950s. ![]() As the Oklo-reactor demonstrates, the ruthenium-compounds remain stable even if exposed to radioactivity and corrosion by water over vast geological periods.Oklo natural reactor as seen in underground mining operations. If so, containers made of ruthenium alloys could be used to safely store radioactive waste for a very long time. The scientists believe that the radioactive plutonium and cesium were encapsulated and safely isolated from the environment by a shell of ruthenium-compounds. Native ruthenium is a rare and inert metal often associated with ore of other elements. In rocks recovered from the Oklo mine, barium (the 'trace' left by the former radioactive elements) is not found evenly distributed, but rather found in nests surrounded by a thin layer of ruthenium-compounds. and published in the journal PNAS has investigated how the Oklo-reactor was able to work so long and yet not pollute the environment. Research by a team of scientists of the US Naval Research Laboratory in Washington D. By studying the Oklo-reactor, scientists hope to find a way to safely dispose of nuclear waste as produced by modern reactors. Steel will rust, concrete can leak and even glass is damaged by the emitted radiation. The problem is that we don't know what materials to use for the containers to store the waste. A permanent repository for nuclear waste must contain toxic elements and radioactivity for at least 100,000 years. Many experts believe that nuclear energy could be a temporary solution until renewable energy sources are ready to meet the demand. Unfortunately, nuclear energy comes with radioactive waste. During this process, however, no harmful radioactivity has leaked into the environment.Īs t he planet warms due to our carbon emissions, burning oil and coal is no longer a sustainable way to meet humanity’s hunger for energy. Over time the Oklo-reactor has produced large quantities of toxic plutonium and cesium-isotopes, which have since decayed into stable and harmless barium. ![]() As the uranium decays, it forms other radioactive elements fueling the reactor. Then water that infiltrated the formation along faults slowed down the emitted neutrons enough to sustain slow and stable nuclear fission. Weathering of magmatic rocks and bacterial activity concentrated the uranium enough to start a nuclear chain reaction. In the Oklo-reactor, two factors came together to sustain a slow nuclear fission for hundreds of thousands of years. |
