9856_96 | history of Cuba. Many of them worked at a later time at the newly created Centro para la |
9856_97 | investigación y desarrollo de la música cubana (CIDMUC), founded in 1978. |
9856_98 | From this group we should mention two renowned musicologists that frequently worked in |
9856_99 | collaboration with each other: Victoria Elí (b. 1945) and Zoila Gómez (b. 1948). We should also |
9856_100 | mention Tamahra Martín (b. 1945), who dedicated two books to the Cuban choral music: “La música |
9856_101 | coral en Cuba” (1987) and “Música Coral” (1990). |
9856_102 | Two other important musicologists from this generation are: Alberto Alén Pérez (b. 1948) and |
9856_103 | Rolando Antonio Pérez Fernández (b. 1947). Alberto Alén applied his extensive knowledge of |
9856_104 | psychology and statistics to musical form analysis as well as music pedagogy, in publications such |
9856_105 | as: “La forma de las formas musicales” and “Diagnosticar la musicalidad”. Rolando Pérez developed |
9856_106 | extensive investigations about Afro-Cuban music and is well known for having documented and |
9856_107 | analyzed the process of transition from ternary rhythms to binary rhythms of the Cuban and Latin |
9856_108 | American popular music, during the 18th and 19th centuries, in his book: “Proceso de binarización |
9856_109 | de los ritmos ternarios africanos en América Latina (1987).” |
9856_110 | Olavo Alén (b. 1947) has closely followed the steps of Argeliers León in his studies of Afro-Cuban |
9856_111 | music and, most importantly, has elaborated and expanded León's theory of “generic complexes”, in |
9856_112 | works such as: “Géneros de la música cubana” from 1976. |
9856_113 | Those theories have been strongly refuted by other musicologists such as Leonardo Acosta, who |
9856_114 | explains in his article “De los complejos genéricos y otras cuestiones”: |
9856_115 | Other members of this Group are renowned musicologists Martha Ezquenazi (1949), Jesús Gómez Cairo |
9856_116 | (1949) and Dora Ileana Torres (1956). |
9856_117 | Most recently, a group of young Cuban musicologists have earned a well deserved reputation within |
9856_118 | the international academic field, due to their solid investigative work. Some of the most prominent |
9856_119 | members of this group are: Miriam Escudero Suástegui, Liliana González Moreno, Iván César Morales |
9856_120 | Flores and Pablo Alejandro Suárez Marrero. |

9857_0 | The LAV III, originally named the Kodiak by the Canadian Army, is the third generation of the Light |
9857_1 | Armoured Vehicle (LAV) family of infantry fighting vehicles built by General Dynamics Land Systems |
9857_2 | – Canada (GDLS-C), a London, Ontario, based subsidiary of General Dynamics. It is a license-built |
9857_3 | version of the Mowag Piranha IIIH. It first entered service in 1999, succeeding the LAV II. It is |
9857_4 | the primary mechanized infantry vehicle of both the Canadian Army and the New Zealand Army. It also |
9857_5 | forms the basis of the Stryker vehicle used by the U.S. Army and other operators. The Canadian Army |
9857_6 | is upgrading its LAV IIIs to the LAV 6 standard. |
9857_7 | Development |
9857_8 | By July 1991, the Canadian Armed Forces had identified the need to replace their aging fleet of |
9857_9 | 1960s and 1970s era armoured personnel carriers. As a result, $2.8 billion was earmarked for the |
9857_10 | Multi-Role Combat Vehicle (MRCV) project by the sitting Conservative government. The mandate of the |
9857_11 | MRCV project was to provide a series of vehicles based on a common chassis which would replace the |
9857_12 | M113 armored personnel carrier, Lynx reconnaissance vehicle, Grizzly armoured personnel carrier, |
9857_13 | and Bison armoured personnel carrier. The project was, however, deemed unaffordable and cancelled |
9857_14 | by March 1992. |
9857_15 | By 1994, after the Liberal Party had returned to government, the army was still in need of new |
9857_16 | vehicles. As a result, the army embarked on the Light Armoured Vehicle Project, which would adapt |
9857_17 | parts of the MRCV Project, and be implemented incrementally to spread out the costs. Also, the |
9857_18 | requirement to replace the Bisons was dropped. The first phase of the project saw the selection of |
9857_19 | the LAV II Coyote Reconnaissance Vehicle to replace the Lynx. |
9857_20 | General Motors Diesel proposed a license-built variant of the 8x8 Mowag Piranha IIIH incorporating |
9857_21 | the turret and weapon system of the Coyote. In August 1995, it was announced that GM Diesel (later |
9857_22 | renamed GM Defense, and subsequently purchased by General Dynamics Land Systems of London, Ontario) |
9857_23 | had been awarded the contract to produce the LAV III which would replace the Grizzly and a large |
9857_24 | portion of the M113 armoured personnel carriers. |
9857_25 | Future
LAV 6 |
9857_26 | In October 2011, GDLS-Canada was awarded a contract to upgrade 409 of the service's 651 LAV III |
9857_27 | APCs to the LAV 6 standard. Four variants were ordered: an infantry section carrier, a command |
9857_28 | post, an observation post and an engineer vehicle. The upgrade was expected to extend the service |
9857_29 | life of the vehicle to 2035. In February 2017, the service awarded GDLS-Canada a $404 million |
9857_30 | contract to upgrade 141 more LAV IIIs. In August 2019, GDLS-Canada received a four-year, $3 billion |
9857_31 | deal to build 360 armoured combat support vehicle variants. The first of these rolled off the |
9857_32 | assembly line in May 2021. |
9857_33 | Design
Mobility |
9857_34 | The LAV III is powered by a Caterpillar 3126 diesel engine developing and can reach speeds above |
9857_35 | 100 kilometres per hour. The vehicle is fitted with 8x8 drive and also equipped with a central tire |
9857_36 | inflation system, which allows it to adjust to different terrain, including off-road. The LAV III |
9857_37 | is fitted with a modern anti-locking brake system (ABS). Unlike earlier versions of the LAV, the |
9857_38 | LAV III does not have amphibious capabilities. |
9857_39 | The LAV III faces the same concerns that most other wheeled military vehicles face. Like all |
9857_40 | wheeled armoured vehicles, the LAV III's ground pressure is inherently higher than a tracked |
9857_41 | vehicle with a comparable weight. This is because tires will have less surface area in contact with |
9857_42 | the ground when compared to a tracked vehicle. Higher ground pressure results in an increased |
9857_43 | likelihood of sinking into soft terrain such as mud, snow and sand, leading to the vehicle becoming |
9857_44 | stuck. The lower ground pressure and improved traction offered by tracked vehicles also gives them |
9857_45 | an advantage over vehicles like the LAV III when it comes to managing slopes, trenches, and other |
9857_46 | obstacles. |
9857_47 | The LAV III can somewhat compensate for these effects by deflating its tires slightly, meaning that |
9857_48 | the surface area in contact with the ground increases, and the ground pressure is slightly lowered. |
9857_49 | However, wheels offer several advantages over tracked vehicles, including lower maintenance for |
9857_50 | both the vehicle and road infrastructure, quieter movement for improved stealth, greater speed over |
9857_51 | good terrain, and higher ground clearance. Wheeled vehicle crews are also more likely to survive |
9857_52 | mine or IED attacks than the crew of a similarly armoured tracked vehicle. |
9857_53 | The LAV III's turret gives the vehicle a higher centre of gravity than the vehicle was initially |
9857_54 | designed for. This has led to concerns that the vehicle is more likely to roll over on uneven |
9857_55 | terrain. |
9857_56 | While there have been several recorded rollovers (about 16), the most common cause was found to be |
9857_57 | unstable terrain, specifically road shoulders unexpectedly giving away beneath the vehicle. The |
9857_58 | weight balance of the LAV III is taken into consideration during driver training, largely |
9857_59 | mitigating the chances of a rollover. |
9857_60 | Protection |
9857_61 | The basic armour of the LAV III, covering the Standardization Agreement STANAG 4569 level III, |
9857_62 | which provides all-round protection against 7.62×51mm NATO small calibre rounds. A ceramic appliqué |
9857_63 | armour (MEXAS) can be added, which protects against 14.5×114mm heavy calibre rounds from 500 |
9857_64 | meters. In December 2008 the Government of Canada awarded EODC Engineering, Developing and |
9857_65 | Licensing Inc. C$81.5 million worth of contracts to provide for add-on-armour kits, modules and |
9857_66 | spares for its LAV III wheeled armoured personnel carriers. This armour kit is intended to provide |
9857_67 | increased protection against improvised explosive devices (IED), explosively formed penetrators and |
9857_68 | 30 mm caliber armour piercing rounds. The LAV III can be also fitted with cage armour, which |
9857_69 | provides protection against shaped charges. The LAV III is fitted with a nuclear, biological, |
9857_70 | chemical (NBC) filtration system accompanied with a GID-3 chemical detector and AN/VDR-2 radiation |
9857_71 | detector systems. The LAV III was designed to produce a very low and very compact structure to |
9857_72 | minimize radar and IR-signatures. The LAV III also uses heat-absorbing filters to provide temporary |
9857_73 | protection against thermal imaging (TIS), image intensifiers and infrared cameras (IR). General |
