Their first obstacle is simply finding the path - a metaphorical representation of the confusion that besets everyone on his or her journey through life. Where their friends follow the path of outward heroism in battle, for Frodo and Sam, heroism must come through endurance, the dogged determination to complete their task regardless of the obstacles. The landscape is forbidding, and they have little hope of getting into the Black Land, let alone getting out again. While Merry and Pippin meet the Ents, and Legolas, Gimli, Aragorn, and Gandalf begin the battle for Middle-earth, the two hobbits must make their slow, painful way to Mordor. Frodo resolves to continue.Īfter leaving the Fellowship at Parth Galen, Frodo and Sam have only each other to depend on. Faramir warns the hobbits against following Gollum, but he cannot offer any alternative. Frodo does so, but Gollum feels betrayed his fragile trust is broken. Frodo begs that Gollum's life be spared, and Faramir agrees if Frodo will help the Gondorians to capture him. In the night, Faramir wakes Frodo and shows him Gollum fishing in the sacred pool of Henneth Annûn. Sam accidentally reveals that Frodo's burden is the Ring, but Faramir stands by his word, making no attempt to take it. Not knowing what it is, Faramir swears that he would not pick up the Ring if it lay in the road. Nevertheless, Faramir takes Frodo and Sam to his hidden base, Henneth Annûn, and along the way tells Frodo that he knows that the hobbit did not part well with Boromir, and that he now carries an item of great importance to the Enemy. When Frodo tells him to ask Boromir, Faramir reveals that Boromir, his brother, is dead. The hobbits witness the ambush, and Sam is thrilled to see an oliphaunt.Īfter the battle, Faramir finds Frodo's explanations unsatisfying. They are part of a company ambushing Sauron's forces, led by Faramir. The fire attracts men of Gondor, who hold Frodo and Sam captive. Gollum would rather eat them raw and leaves rather than watch Sam spoil the meat by cooking it. Gollum goes hunting during their midday rest, returning with rabbits. The countryside as they journey south becomes green and pleasant, blooming with herbs and flowers, although marked by signs of disease. Sam mistrusts any suggestion from Gollum, but Frodo chooses to accept his help. In the mountains above Minas Morgul, the home of the Ringwraiths, a narrow path leads by many stairs over the mountains and into Mordor itself. Gollum begs them not to enter, and he reveals that there is another way, extremely difficult and dangerous, but safer. The Gate looms above them, manned by countless watchful orcs, with no way to approach unseen. For the moment the promise wins, but Gollum has begun to imagine ways to get the Ring and become its master, letting him obey the word of his promise, if not its spirit.Īt the Black Gate, Frodo and Sam realize the hopelessness of their quest. During a daytime rest, Sam overhears Gollum talking to himself, torn between his desire for the Ring and his promise to obey Frodo. A Nazgûl passes overhead, nearly paralyzing Gollum with fear, but the three travelers find their way through to the ashy wasteland beyond. Gollum leads them from the hills into the Dead Marshes, a haunted swamp. Happy to be released, Gollum begins to go by his true name, Sméagol, and seems eager to please Frodo. Frodo accepts the promise, knowing that the Ring will hold him to it. Gollum agrees to guide Frodo and Sam to the Black Gate, and he swears by the Ring to obey its master. They know Gollum is following, and the hobbits barely manage to capture and bind the wiry creature.

Who Should Train Muscular Endurance (And Why)? Unless you have a specific reason to do otherwise, target 15-100 reps per set for muscular endurance training. The reason is that anything past 100 reps per set is so lightweight it will likely tap into the aerobic energy system as opposed to conditioning your Type I muscle fibers for greater endurance capabilities. You can potentially even do hundreds of reps per set, but unless your specific goal is to do hundreds of reps, there is probably a point of diminishing returns around 100 reps. Unlike training for strength or hypertrophy, which usually involves 1-12 reps per set, lifting for muscular endurance uses exclusively higher reps.įifteen reps per set is the minimum volume for muscular endurance, and 25+ reps is typical. It may sound obvious, but you can’t significantly improve muscular endurance unless you train with enough reps to fatigue Type I muscle fibers. Therefore, your training routine should reflect your goals. Muscular Endurance Rep RangesĪccording to the exercise science principle called specific adaptation to imposed demand, or SAID for short, your body can only adapt to the demands you place upon it. These adaptations include hypertrophy (growth) of Type I fibers, heightened oxidative metabolism (fat-burning ability) of Type I and Type II fibers, capillarization (formation of new blood vessels to deliver oxygen and nutrients to muscles), and greater mitochondrial density for increased energy production. In contrast, smaller Type I fibers generate less initial power, but can stay active for far longer.īecause muscular endurance exercises typically involve higher rep ranges compared to strength and power training, they target slow-twitch Type I muscle fibers.Īfter 2-4 weeks of muscular endurance training, many beneficial fitness-related adaptations occur in your body. Larger, stronger Type II fibers are the main movers for powerful, explosive, short-burst, or max strength activities. Your skeletal muscles contain two primary categories of muscle fibers: Type I (known as “slow-twitch”) and Type II (also called “fast-twitch”). The Science of Muscular Endurance Training AdaptationsĪlthough muscular endurance training can tax all three of your body’s energy systems ( ATP-CP, glycolytic-lactate, and aerobic-oxidative), it works primarily by targeting specific muscle groups and fatiguing their long-lasting muscle fibers. The breakdown of form while rucking can occur well before you reach the limit of your aerobic fitness.Īside from pushup tests and other fitness standards, most real-world activities involve other fitness qualities besides just muscular endurance. Rucking overloads your postural muscles, and people who aren’t experienced with rucking often have to stop for safety reasons when their form breaks down. One such hybrid example is rucking, which is walking or marching with a weighted pack or vest up to one-third of your bodyweight. In other aerobic-dominant activities, though, muscular endurance may be a limiting factor. You’d need to focus on aerobic endurance training.Ī competent marathoner may become a much better runner and lower their injury risk by increasing muscular endurance, but aerobic endurance is the core fitness quality required to finish a marathon in the first place. If you can’t finish a marathon, no amount of muscular endurance training will make it possible. That means the limiting factor was their inadequate aerobic fitness, not a lack of endurance in the muscle fibers of their legs. On the other hand, someone who is unable to finish a marathon can probably still walk shortly after their failed attempt. Increasing your aerobic fitness would be totally irrelevant to doing lots of pushups. Instead, it’s most likely because all the muscle fibers that allow you to perform a pushup finally became exhausted.Īnd to get better at the maximum pushup test, you’d need to practice doing high-rep pushups. If you’re attempting to do as many pushups as possible, when you reach your limit, it’s not because you had to stop and catch your breath. Here’s the technical definition of muscular endurance as a fitness quality: “the ability of muscles to remain active for extended periods of time while resisting or recovering from fatigue.”Īs an illustration, let’s examine the differences between the maximum pushup test (a pure muscular endurance activity) and a marathon. The goal of muscular endurance training is to perform more reps or keep a muscle group active for a longer period of time. Sample Muscular Endurance Training Program.The Top 10 Muscular Endurance Exercises & Activities. Time Bonus: Counts down from 20,000 points while playing, indicated in the top right corner of the game.Removing all the cards in a column scores 1,000 points x Card Run Multiplier.Īfter finishing a round, there are three bonuses: time bonus, deck cards bonus and round number bonus. Using wild cards counts to your card run if they are in the layout, so it's often worth taking a moment to plan your moves.Įach removed card scores 200 points x Card Run Multiplier. When you turn a card in the deck, the multiplier will reset to zero. This multiplier grows each time you play a card from the layout without turning over one of the deck cards. The secret to getting the most points is to try to maximize your card run multiplier. This can be really helpful if you are confronted with a few choices of cards that you can play, allowing you to work out which option might remove more cards from the layout. It's worth noting that in this solitaire game, you can use the undo button to peek under the deck cards at the bottom. Wild Cards can be played at any point you desire and of course absolutely any card can be placed on top of them. The Ace is both high and low, and either a 2 or a King can be played on it. Cards can be removed from the layout if they are one higher or lower than the visible deck card shown at the bottom. How many rounds can you complete? Gameplay Try to win as many rounds of golf solitaire as you can by removing all the cards. Family: Adding & Pairing Solitaire Games. The new loadout for MUL-T, the saw blade, makes MUL-T a melee character with none of the benefits. Sadly, this update did nothing to help him, in fact, it kinda made him weaker. MUL-T is a good character and has been for a while now. (Just put it on Drizzle and do the teleporter immediately). To unlock the Commando’s Tactical Slide, you need to clear the first stage in less than 5 minutes. To unlock the Commando’s Frag Grenade, you need to clear 20 stages as the Commando without picking up a lunar item. To unlock the Commando’s Phase Blast you will need to land the killing blow on an overloading worm. Get the new Tactical Slide and use that for higher DPS potential. Whether you want to switch between the new special or the old is mainly personal preference and or playstyle differences. To shorten things up, get the new secondary Phase Blast. Also, if you use the ability while jumping you get a slight boost in the air instead of sliding, making some terrain traversable. Secondly, Tactical Slide can be improved with move speed, which Tactical Dive cannot. First, you can shoot while sliding, meaning more DPS. There are two things that make this superior to Tactical Dive (the OG). When you press shift (or whatever button you use) you will slide forward. Tactical Slide replaces his old combat roll with something you see out of a Call of Duty. Tactical SlideĪs of the new Artifact update, the Commando has also received a new utility skill. However, if you feel like you are lacking AOE damage as the Commando, then I would recommend the Frag Grenade. The stun it provides and the scaling factor makes it a whole lot better in my opinion. Instead, it is an entirely new ability that caters to a different playstyle which is how I prefer these loadouts to be.įor the most part, I would go with his old special. The Frag Grenade is not a direct upgrade to the Commando’s previous special. Other than a new secondary, the Commando also got a new special ability, Frag Grenade. The only negative repercussions being a decreased proc coefficient per shot (but it shoots eight so it should proc more) and the fact it can’t travel through the terrain, a largely irrelevant factor. His new ability Phase Blast is basically just an upgrade over his old ability Phase Round. However, the skills 2.0 update has given the Commando some new life. This is something more or less expected, as he is the “vanilla” survivor in Risk of Rain 2 and serves as a starting point for all new players. He couldn’t do good AOE damage or single target damage to literally save his life. To say the Commando sucked at everything is pretty fair.

Every tape formula has a distinctive smell and some brands carry a distinctive family smell it's relatively easy to learn how to identify a tape formula by smell alone by storing a reel of tape in a plastic bag as well as the box and just just sniffing the bag storing the tape. Once you find a tape formulation you like, use it exclusively. The reason they use 1khz is because 1khz is in the middle of the range of the human voice (100Hz-3Khz) and at 1Khz the power is at max and doesnt roll off dramatically like it does at higher frequencies. wait until there's a minute or three of tape on the take up spool or hub, then start. It goes on to talk about comparing your two speakers, and using it to test your cabling. Grab some tape before you attempt a bias setting ie don't use the tape at the start of the hub or reel. Ideally the playback will show the same Vu level as the record, but somewhat more important is the playback levels of the two tones relative to each other. Record the two bias setting tones at -20Vu (cassette) -10Vu (consumer tape deck) or 0Vu (professional tape deck). A 1 Khz tone can also be useful, however. 400 Hz is a good second tone, you only use the two. The simplest and free online tone generator for creating pure audio signals of any frequency from 1 Hz to 20000 Hertz (20 kHz), sine sound signal generator. You can substitute 20 Khz if the machine uses at least 1/2" tape and you are recording at 30 ips. The frequency of the master oscillator is given by the equation. The output frequency is programmable via a single resistor and the connection to its divider pin (labeled DIV). Stay tuned, if anything works I'll draw it up on that original thread.Īn upper limit for bias tone generator would be 10 Khz for any 1/4" tape machine or smaller (eg cassette 1/8"). The LTC6900 is a 5 volt low power circuit available in an SOT-23 (5 pin) package. I'm trying to fly the drill it yourself lexan board over the mcmelecttonics pcb, but holiday preparation has got in the way. I've got some new $.85 DIP project boards from mcmelectronics, the DIP socket fits and solders fine but there is no room on it for the 15 discrete parts involved. The 700 Hz signal falls in the passband of an audio system and is easily distinguished from either 400 Hz or 1 kHz signals. I have been trying to get it packaged with test circuit 12 on the datasheet () but I've mostly proved solder sticks better to drill it yourself lexan and beigh CB boards than it does to socket pins. You can still get the IC in DIP package for $6 at. The Exar XR2206 sine wave generator IC looks to be a lot more professional, but the nifty kit that was built on top of this is long gone. BTW, the power supplie I have dedicated to this is a 4 amp 12 V CT battery charger transformer on an open frame that produces 19.5 V full wave rectified (1500 uf cap) or 9.5 V half wave rectified (2200 uf cap) both using the minus rail as reference. The GE circuit is not producing any tone I can hear through the amp I'm trying to repair, that does play a transistor radio a bit into a speaker before motorboating. Don't know if the 6 mv was ~800 hz (with. Have tried both 2n2905 at reversed polarity, and 2n3904 with as drawn polarity so far, got 6 mv out a little while but the o-scope sweep quit, I guess it blew the power supply. I'm trying to build a 2 transistor oscillator from the GE Transistor manual 7th edition, it worked with a lot of hum imposed but when I put enough capacitance on the rail to get rid of the hum it just sits there. The EDN link for an amplitude stable oscillator leads to some op amp circuit using an op amp I don't have. The ubiquitous NE5532 is about the slowest but is still 2 or 4 times faster than it needs to be for audio purposes.Check out this link for a build it yourself: The Eliot project has way too many parts for my taste, a split supply which is another 6-9 parts, plus some weird light bulb I don't have as a PTC Resistor. Note however that the 741 is the only chip around that is limited in that way. NOW that is! The humble 741 op amp will start to droop at 10kHz or so if you want 20dB of gain. Op amps can deliver any frequency you like from DC to the limit of their gain bandwidth product. Modern solid state electronics is pretty well 'aperiodic'. The start of tape recording and especially cassettes meant the 'pivot point' of the EQ curve was moved down to 300Hz iirc because 1kHz was already 'on the slope'. Then, back in the day when all we had was valves and transformers to amplify signals, one k was 'easy', below about 100Hz transformers start to droop and get more distorted and above 10kHz the higher impedance of valve circuits and cable capacitances began to lose you signal.ġ000Hz is not all embracing however. You can see that the 'cutting' / replay EQ curves pivots about 1kHz. That ^ was probably one reason 1kHz was chosen as a reference. |
