Light armored vehicles correspond to an adaptable model of weapon systems whose common factor lies in the protected transport of troops. This type of vehicle relates the concepts of armor, firepower, transport, passability, and speed, in pursuit of generating a balanced system, rapid deployment, capable of adapting to different environments, needs and threats at a comparatively lower cost than other weapons more specific and heavy such as MBTs. Due to their flexibility in employment, they can participate in both war and non-war operations (MOOTW), mainly in international cooperation and HA / DR operations at the national level. This article will describe the gestation, and current use of LAV systems developed particularly in Canada since the 1960s, which to date are used massively by the armed forces of the United States, Canada, Australia, Colombia, among others; and its competitive and cooperative advantages both nationally and internationally.
LAV III today
The change in focus on defense matters after the Soviet Union’s disappearance generated a different vision of the development of military capabilities, tending to systems adaptable to different situations and environments. For this particular case, the need for heavily armored vehicles was reduced, increasing the demand for more versatile and lighter vehicles. One of the forces worldwide that had demonstrated the feasibility of using this type of means in conflict areas was the United States Marine Corps. They, through a large fleet of LAV II systems, verified their capabilities in varieties of functions such as anti-aircraft and armor actions, command and control, troop transport, fire support, and surveillance.
However, Canada’s concept was to downgrade its tank units, replacing them with a medium with enough armor to deal with medium calibers and convenient firepower to destroy similar and even heavier armored tanks. According to these general requirements, the concept of the LAV III was born, this time a 30 ton carriage, which was compared in all its functions with the existing M-113. The tests yielded favorable results for the new vehicle, especially in its version with a stabilized tower of 25 mm. It allowed it to face adversaries at a greater distance with various types of ammunition and even face other tanks that could penetrate its armor (T-55 or similar). The cost of its rolling system was much simpler and more affordable than that of a tracked vehicle, lowering logistics costs in maintenance, maintenance, and operation.
On the other hand, its armor contributed to generate higher survival rates for the crew and troop on board, which, despite its weight, continued to be transportable in higher-load military aircraft, such as the C-130 Hercules. Its hydropneumatic suspension was far superior to its predecessors, allowing it to perform actions at higher speeds and contribute to the feeling of comfort in the onboard troop. The observation and aiming systems were improved to thermal versions, integrating a computer self-diagnosis system for failures and fire control. The on-board personnel compartment was expanded, adding a digital repeater screen, associated with the observation and aiming systems of the tower, which allowed the implementation of a live panorama system, reducing the degree of uncertainty before landing. Finally, an air conditioning system was integrated, which allowed it to operate in theaters with high temperatures, in addition to having an early detection system for chemical agents and individual respiration systems, allowing it to operate in environments of nuclear and biochemical threat.…
We tend to think that most violinists choose their instruments in part. After all, they appreciate the bright, high-pitched sound that can be played going up the Mi string, and that the violists chose their instrument because they got confused the day they went to pick it up at the store… -I’m sorry, I couldn’t resist. In any case, most of us, “high-stringed” musicians, in general, feel quite comfortable and satisfied in our situation. But from time to time – at least I’m sure most of you do too – we wonder what it would be like to delve into that bass string of C of the cello and rumble a bit on the whole stage; However, we violinists (the first violins, especially) would never admit that we are envious of another string instrument. (or viola) can sound bass notes – those JS Bach cello suites you’ve been looking for a violin transcript for? Better practice reading the F-key a little and play them in their original version mmc996! How do you wonder? Well read on, there are a couple of easy and fun ways.

The Super-Sensitive Sensicore range of high-quality person strings offers a complete selection of possible extended tonal range strings. In addition to ‘octave strings’ that sound an octave below the violin’s Sol-Re-La-Mi (GDAE), they make a violin scale strings Do- C- (just like D’Addario does ) and a set of C octave strings, as well as violin strings that come down from the Sol string in fifths (that is, Fa, Bb and Mib).
Thus, a violinist could create a small viola from his instrument by removing the Mi string, shifting the Sol-Re-La strings up one position, and adding a Do string at the bottom. Similarly, you could substitute the entire octave low-end string set, Sol-Re-La-Mi (GDAE) to create a ‘baritone’ violin, or an octave Do-Sol-Re-La (CGDA) set for a cello at shoulder a violin size cello range instrument, usable over the shoulder!
Do violists have similar options, including a Fa string, Do-Sol-Re-La (CGDA) octave strings – again a portable-sized cello-sounding viola – or the deranged option? Of climbing with a rope large scale viola Mi (E)!
Listen to heavy metal violinist Earl Maneein playing the “shoulder cello” at the ElectricViolinShop store. We have assembled this “14-inch viola with Sensicore Octave CGD and A strings.
If you want to play on the extended range bass strings, you will need a bow capable of holding on to them enough to produce a good tone. Violinists could use a viola bow, but we highly recommend the CodaBow Joule series, the first bow specifically designed with extended range instruments in mind. These bows work very well with octave strings or extended-range bass strings, and CodaBow has also made versions for viola and cello. They’re great bows for normal range strings, too, so if you’re looking in stores to buy a new bow and plan to ever play in the extended range, why not kill two birds with one stone?
It should be noted that, depending on how extreme the sound alteration you make to your instrument with the new string, your instrument may require some modifications to accommodate the greater thickness of the lower strings. No alteration should be necessary to add a C-C- viola string to a violin, or a bass F (F) or E (E) alto to a viola, but when incorporating the lower octave strings, For larger sizes, note that the bridge and nut grooves should be wider, as well as the micro-tuner holes for the string should be consistent. So, to make your mini cello, it is better to use your second violin before your Guarneri!…
More than 600,000 people in the United States turn to cannabis for pain relief – and there is strong scientific evidence for its effectiveness.
In a recent Canadian study, cannabis even calmed laboratory rats with arthritis. Surprisingly, there is (as yet) little evidence from human studies for the most common type of arthritis, osteoarthritis, the wear-related joint disease that affects 50% of adults 65 and older. Clinical trials are ongoing. But who is waiting? In a 2019 Colorado survey, arthritis was the top reason older adults used cannabis, followed by back pain. Overall, 79% said it helped.
NASEM classifies the scientific evidence on whether you sleep better when cannabis is used as only “moderate.” But that has not made older users slow down. More than one in three people in a Colorado survey tried sleeping marijuana; 86% said it helped. “I have had peripheral neuropathy in my left foot for decades. The blazing pain wouldn’t let me sleep,” says Paul Kinder, who recently attended a seminar on medical marijuana near his home at The Villages, to learn more. “Now, I am using cannabis, and I can sleep.
Depression, anxiety, and PTSD
In a recent survey, one in five older adults surveyed resorted to using medical marijuana to dispel low moods and calm chronic tension. More than 90% said it helped.
So far, there is little data for these mental health problems. We will know more soon. At least seven studies of cannabis for anxiety or depression are ongoing in the United States and worldwide. At least six studies are also done for PTSD. For now, small studies and surveys give clues to benefits and problems —, particularly for depression.
As with any medication, dosage matters: more was not better. The bad news: Over time, her continued depression got a little worse. According to the researchers, regular use could change cannabinoid receptors in the brain and increase vulnerability to negative mood states. By quitting using marijuana, you can back down.…
