Lázaro Cárdenas del Río was a general in the Constitutionalist Army during the Mexican Revolution and a statesman who served as President of Mexico between 1934 and 1940. He is best known for nationalization of the oil industry in 1938 and the creation of Pemex, the government oil company, he revived agrarian reform in Mexico, expropriating large landed estates and distributing land to small holders in collective holdings. Although he was not from the state of Sonora, whose generals had dominated Mexican politics in the 1920s, Cárdenas was loyal to Sonoran general and former president Plutarco Elías Calles. Calles had founded the National Revolutionary Party, in the wake of the assassination of Sonoran general Alvaro Obregón, who served as president and was president-elect in 1928. Cárdenas was Calles's hand-picked candidate in 1934 to run for the presidency. While Calles did not hold the title of president, he had remained the power behind the presidency, expected to maintain that role when Cárdenas took office.
However, Cárdenas out-maneuvered him politically and forced the former president into exile, establishing Cárdenas's legitimacy and power in his own right during his remaining time in office. In 1938, Cárdenas transformed the structure of the party Calles founded, creating the Partido de la Revolución Mexicana, based on sectoral representation of peasants via peasant leagues, unionized workers and the Mexican army. Cárdenas's incorporation of the army into the party structure was a deliberate move to diminish the power of the military and prevent their traditional intervention in politics through coups d'état. An important political achievement of Cárdenas was his complete surrender of power in December 1940 to his elected successor, Manuel Ávila Camacho, a political moderate without a distinguished military record. Cárdenas has been revered as "the greatest constructive radical of the Mexican Revolution," for reviving its ideals, but he has been criticized as an "authoritarian populist." According to numerous opinion polls and analysts, Cárdenas is considered as the most popular Mexican president of the 20th century.
Lázaro Cárdenas del Río was born on May 21, 1895, one of eight children in a lower-middle-class family in the village of Jiquilpan, Michoacán, where his father owned a billiard hall. After the death of his father, from age 16 Cárdenas supported his family. By the age of 18, he had worked as a tax collector, a printer's devil, a jail keeper. Although he left school at the age of eleven, he used every opportunity to educate himself and read throughout his life works of history. Cárdenas set his sights on becoming a teacher, but was drawn into the military during the Mexican Revolution after Victoriano Huerta overthrew President Francisco Madero in February 1913. Michoacán was far from the revolutionary action that had brought Madero to the Mexican presidency, but after Huerta's coup and Madero's assassination, Cárdenas joined a group of Zapatistas, but Huerta's forces scattered the group, where Cárdenas had served as captain and paymaster. Since revolutionary forces were voluntary organizations, his position of leadership points to his skills and his being paymaster to the perception that he would be honest in financial matters.
Both characteristics followed him through his subsequent career. He escaped the Federal forces in Michoacán and moved north where he served with Álvaro Obregón Pancho Villa, after 1915 when Villa was defeated by Obregón to Plutarco Elías Calles, who served Constitutionalist leader, Venustiano Carranza. Although Cárdenas was from the southern state of Michoacán, his key experiences in the Revolution were with Constitutionalist northerners, whose faction won. In particular, he served under Calles, who tasked him with military operations against Yaqui Indians and against Zapatistas in Michoacán and Jalisco, during which time he rose to a field command as general, in 1920 after Carranza was overthrown by northern generals, Cárdenas was given the rank of brigadier general at the age of 25. Cárdenas was appointed provisional governor of his home state of Michoacán under the brief presidency of Adolfo de la Huerta. Cárdenas was a political protégé of Calles, but his ideological mentor was revolutionary General Francisco J. Múgica, a anticlerical, secular socialist.
President Calles appointed Cárdenas Chief of Military Operations in the Huasteca, an oil producing region on the Gulf Coast. Cárdenas saw first hand the operations of the foreign oil companies. In the Huasteca, U. S. oil companies extracted oil, avoided taxes owed to the Mexican government, treated the region as “conquered territory.” Múgica was posted to the Huasteca and he and Cárdenas became close. During their time in the Huasteca, Múgica told Cárdenas that “socialism the appropriate doctrine for resolving conflicts in Mexico.” Cárdenas was appointed governor of his home state of Michoacan in 1928, wracked by the political conflict between state and Church, the known as the Cristiada. His ideological mentor Múgica had served as the state’s governor, had attempted to counter the power of the Roman Catholic Church through laws, he mobilized groups to support his positions, creating “political shock troops,” consisting of public school teachers and members of a disbanded agrarian league, forming the Confederación Revolucionaria Michoacana del Trabajo, under the slogan of “Union, Work.”
The organization was funded by the state government. It became the single-most powerful organization representi
National Institutes of Health
The National Institutes of Health is the primary agency of the United States government responsible for biomedical and public health research. It was founded in the late 1870s and is now part of the United States Department of Health and Human Services; the majority of NIH facilities are located in Maryland. The NIH conducts its own scientific research through its Intramural Research Program and provides major biomedical research funding to non-NIH research facilities through its Extramural Research Program; as of 2013, the IRP had 1,200 principal investigators and more than 4,000 postdoctoral fellows in basic and clinical research, being the largest biomedical research institution in the world, while, as of 2003, the extramural arm provided 28% of biomedical research funding spent annually in the U. S. or about US$26.4 billion. The NIH comprises 27 separate institutes and centers of different biomedical disciplines and is responsible for many scientific accomplishments, including the discovery of fluoride to prevent tooth decay, the use of lithium to manage bipolar disorder, the creation of vaccines against hepatitis, Haemophilus influenzae, human papillomavirus.
NIH's roots extend back to the Marine Hospital Service in the late 1790s that provided medical relief to sick and disabled men in the U. S. Navy. By 1870, a network of marine hospitals had developed and was placed under the charge of a medical officer within the Bureau of the Treasury Department. In the late 1870s, Congress allocated funds to investigate the causes of epidemics like cholera and yellow fever, it created the National Board of Health, making medical research an official government initiative. In 1887, a laboratory for the study of bacteria, the Hygienic Laboratory, was established at the Marine Hospital in New York. In the early 1900s, Congress began appropriating funds for the Marine Hospital Service. By 1922, this organization changed its name to Public Health Services and established a Special Cancer Investigations laboratory at Harvard Medical School; this marked the beginning of a partnership with universities. In 1930, the Hygienic Laboratory was re-designated as the National Institute of Health by the Ransdell Act, was given $750,000 to construct two NIH buildings.
Over the next few decades, Congress would increase funding tremendously to the NIH, various institutes and centers within the NIH were created for specific research programs. In 1944, the Public Health Service Act was approved, the National Cancer Institute became a division of NIH. In 1948, the name changed from National Institute of Health to National Institutes of Health. In the 1960s, virologist and cancer researcher Chester M. Southam injected HeLa cancer cells into patients at the Jewish Chronic Disease Hospital; when three doctors resigned after refusing to inject patients without their consent, the experiment gained considerable media attention. The NIH was a major source of funding for Southam's research and had required all research involving human subjects to obtain their consent prior to any experimentation. Upon investigating all of their grantee institutions, the NIH discovered that the majority of them did not protect the rights of human subjects. From on, the NIH has required all grantee institutions to approve any research proposals involving human experimentation with review boards.
In 1967, the Division of Regional Medical Programs was created to administer grants for research for heart disease and strokes. That same year, the NIH director lobbied the White House for increased federal funding in order to increase research and the speed with which health benefits could be brought to the people. An advisory committee was formed to oversee further development of the NIH and its research programs. By 1971 cancer research was in full force and President Nixon signed the National Cancer Act, initiating a National Cancer Program, President's Cancer Panel, National Cancer Advisory Board, 15 new research and demonstration centers. Funding for the NIH has been a source of contention in Congress, serving as a proxy for the political currents of the time. In 1992, the NIH encompassed nearly 1 percent of the federal government's operating budget and controlled more than 50 percent of all funding for health research, 85 percent of all funding for health studies in universities. While government funding for research in other disciplines has been increasing at a rate similar to inflation since the 1970s, research funding for the NIH nearly tripled through the 1990s and early 2000s, but has remained stagnant since then.
By the 1990s, the NIH committee focus had shifted to DNA research, launched the Human Genome Project. The NIH Office of the Director is the central office responsible for setting policy for NIH, for planning and coordinating the programs and activities of all NIH components; the NIH Director plays an active role in shaping outlook. The Director is responsible for providing leadership to the Institutes and Centers by identifying needs and opportunities in efforts involving multiple Institutes. Within this Office is the Division of Program Coordination and Strategic Initiatives with 12 divisions including: Office of AIDS Research Office of Research on Women's Health Office of Disease Prevention Sexual and Gender Minority Research Office Tribal Heath Research Office Office of Program Evaluation and PerformancePrevious directors: Joseph J. Kinyoun, served August 1887 – April 30, 1899 Milton J. Rosenau, served May 1, 1899 – September 30, 1909 John F. Anderson, served October 1, 1909 – November 19, 1915 George W.

The spinal cord is a long, tubular structure made up of nervous tissue, that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord; the brain and spinal cord together make up the central nervous system. In humans, the spinal cord begins at the occipital bone where it passes through the foramen magnum, meets and enters the spinal canal at the beginning of the cervical vertebrae; the spinal cord extends down to between the second lumbar vertebrae where it ends. The enclosing bony vertebral column protects the shorter spinal cord, it is around 45 cm in men and around 43 cm long in women. The spinal cord has a varying width, ranging from 13 mm thick in the cervical and lumbar regions to 6.4 mm thick in the thoracic area. The spinal cord functions in the transmission of nerve signals from the motor cortex to the body, from the afferent fibers of the sensory neurons to the sensory cortex, it is a center for coordinating many reflexes and contains reflex arcs that can independently control reflexes.
It is the location of groups of spinal interneurons that make up the neural circuits known as central pattern generators. These circuits are responsible for controlling motor instructions for rhythmic movements such as walking; the spinal cord is the main pathway for information connecting the brain and peripheral nervous system. Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous extension known as the filum terminale, it is about 45 cm long in men and around 43 cm in women, ovoid-shaped, is enlarged in the cervical and lumbar regions. The cervical enlargement, stretching from the C5 to T1 vertebrae, is where sensory input comes from and motor output goes to the arms and trunk; the lumbar enlargement, located between L1 and S3, handles sensory input and motor output coming from and going to the legs. The spinal cord is continuous with the caudal portion of the medulla, running from the base of the skull to the body of the first lumbar vertebra.
It does not run the full length of the vertebral column in adults. It is made of 31 segments from which branch one pair of sensory nerve roots and one pair of motor nerve roots; the nerve roots merge into bilaterally symmetrical pairs of spinal nerves. The peripheral nervous system is made up of these spinal roots and ganglia; the dorsal roots are afferent fascicles, receiving sensory information from the skin and visceral organs to be relayed to the brain. The roots terminate in dorsal root ganglia, which are composed of the cell bodies of the corresponding neurons. Ventral roots consist of efferent fibers that arise from motor neurons whose cell bodies are found in the ventral gray horns of the spinal cord; the spinal cord are protected by three layers of tissue or membranes called meninges, that surround the canal. The dura mater is the outermost layer, it forms a tough protective coating. Between the dura mater and the surrounding bone of the vertebrae is a space called the epidural space; the epidural space is filled with adipose tissue, it contains a network of blood vessels.
The arachnoid mater, the middle protective layer, is named for its spiderweb-like appearance. The space between the arachnoid and the underlying pia mater is called the subarachnoid space; the subarachnoid space contains cerebrospinal fluid, which can be sampled with a lumbar puncture, or "spinal tap" procedure. The delicate pia mater, the innermost protective layer, is associated with the surface of the spinal cord; the cord is stabilized within the dura mater by the connecting denticulate ligaments, which extend from the enveloping pia mater laterally between the dorsal and ventral roots. The dural sac ends at the vertebral level of the second sacral vertebra. In cross-section, the peripheral region of the cord contains neuronal white matter tracts containing sensory and motor axons. Internal to this peripheral region is the grey matter, which contains the nerve cell bodies arranged in the three grey columns that give the region its butterfly-shape; this central region surrounds the central canal, an extension of the fourth ventricle and contains cerebrospinal fluid.
The spinal cord is elliptical in cross section, being compressed dorsolaterally. Two prominent grooves, or sulci, run along its length; the posterior median sulcus is the groove in the dorsal side, the anterior median fissure is the groove in the ventral side. The human spinal cord is divided into segments. Six to eight motor nerve rootlets branch out of right and left ventro lateral sulci in a orderly manner. Nerve rootlets combine to form nerve roots. Sensory nerve rootlets form off right and left dorsal lateral sulci and form sensory nerve roots; the ventral and dorsal roots combine to form one on each side of the spinal cord. Spinal nerves, with the exception of C1 and C2, form inside the intervertebral foramen; these rootlets form the demarcation between the peripheral nervous systems. The grey column, in the center of the cord, is shaped like a butterfly and consists of cell bodies of interneurons, motor neurons, neuroglia cells and unmyelinated axons; the anterior and posterior grey column present as projections of the grey matter and are known as the horns of the spinal cord.

National Polytechnic Institute of Mexico
The National Polytechnic Institute of Mexico, abbreviated IPN, is one of the largest public universities in Mexico with 171,581 students at the high school and postgraduate levels. It is the second best university in Mexico in the technical and engineering domain according to the QS World University Rankings by Subject 2018, it was founded on 1 January 1936 during the administration of President Lázaro Cárdenas del Río as a response to provide professional education to the most disadvantaged social classes in that period, a practice, maintained because it is one of the few vocational schools in the world. The institute consists of 98 academic units offering 293 courses of study, it includes 80 undergraduate and 135 postgraduate programs. Its main campus, called'Unidad Profesional Adolfo López Mateos' or'Zacatenco', is on 530 acres north Mexico City; the IPN is based in Mexico City and its suburbs, but with several research institutes and facilities distributed over 22 states. The institute was founded on January 1, 1936 during the administration of President Lázaro Cárdenas in what had been known as the Ex hacienda Santo Tomás — a large estate owned by Spanish conqueror Hernán Cortés in the 16th century and donated by the federal government.
Prominent astronomer Luis Enrique Erro, former revolutionary Juan de Dios Bátiz Paredes and former minister of education Narciso Bassols were among its initial promoters. During the administration of former director Alejo Peralta sufficient lands were given to IPN. Expropriated lands of Santa Maria Ticomán and San Pedro Zacatenco were used; the construction of what is now the Professional Unit "Adolfo López Mateos" began in 1958. In 1959, former President Adolfo López Mateos, the former minister of education Jaime Torres Bodet, former director of IPN Eugenio Mendez Docurro, inaugurated the first four buildings of Zacatenco, which were occupied by the Superior School of Mechanical and Electrical Engineering and the Superior School of Engineering and Architecture; the institute is organized around 98 academic units including 18 vocational high schools, 26 university colleges, 20 scientific and technical research centers, 17 continuing education centers, 4 units for educational support, 3 support units for education innovation, 8 support units for research and technological and enterprise foment, 2 units affiliated to science, enterprise research and development.
These schools are in Mexico City, although several extension and research facilities are distributed over 22 states. Some units enjoy a high degree of budgetary freedom; the institute as a whole is headed by a director-general appointed by the President of Mexico after some consultation with members of its academic community. Since November 2017, its director-general is Mario Alberto Rodríguez Casas. In addition to its academic endeavors, as part of its cultural promotion strategy, the institute operates'Canal Once', the oldest public broadcast service in Latin America featuring original cultural, scientific and entertainment programming, foreign shows and classic and non-commercial films from all over the world; the Institute offers 80 undergraduate programs leading to four- or five-year bachelor's degrees and 135 postgraduate programs leading to 29 postgraduate diplomas, 70 master's degrees and 36 doctorate degrees. Like most public universities in Mexico, in addition to its undergraduate and graduate schools the institute sponsors several vocational high schools called'Centros de Estudios Científicos y Tecnológicos', most of which are in Greater Mexico City.
Upon completion, they lead to a technician degree. For this level of study, the institute offers 78 technical careers. IPN fields 27 varsity teams in sports or activities such as archery, American football, baseball, body building, boxing, cycling, gymnastics, indoor soccer, karate, mountaineering, soccer, taekwondo, touch football, volleyball and wrestling; the university maintains a fierce rivalry with all the athletic teams from the National Autonomous University of Mexico but have a bitter competition with its football program, the "Pumas Dorados".

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms and evolution. Despite the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis. Sub-disciplines of biology are defined by the research methods employed and the kind of system studied: theoretical biology uses mathematical methods to formulate quantitative models while experimental biology performs empirical experiments to test the validity of proposed theories and understand the mechanisms underlying life and how it appeared and evolved from non-living matter about 4 billion years ago through a gradual increase in the complexity of the system.
See branches of biology. The term biology is derived from the Greek word βίος, bios, "life" and the suffix -λογία, -logia, "study of." The Latin-language form of the term first appeared in 1736 when Swedish scientist Carl Linnaeus used biologi in his Bibliotheca botanica. It was used again in 1766 in a work entitled Philosophiae naturalis sive physicae: tomus III, continens geologian, phytologian generalis, by Michael Christoph Hanov, a disciple of Christian Wolff; the first German use, was in a 1771 translation of Linnaeus' work. In 1797, Theodor Georg August Roose used the term in the preface of a book, Grundzüge der Lehre van der Lebenskraft. Karl Friedrich Burdach used the term in 1800 in a more restricted sense of the study of human beings from a morphological and psychological perspective; the term came into its modern usage with the six-volume treatise Biologie, oder Philosophie der lebenden Natur by Gottfried Reinhold Treviranus, who announced: The objects of our research will be the different forms and manifestations of life, the conditions and laws under which these phenomena occur, the causes through which they have been effected.
The science that concerns itself with these objects we will indicate by the name biology or the doctrine of life. Although modern biology is a recent development, sciences related to and included within it have been studied since ancient times. Natural philosophy was studied as early as the ancient civilizations of Mesopotamia, the Indian subcontinent, China. However, the origins of modern biology and its approach to the study of nature are most traced back to ancient Greece. While the formal study of medicine dates back to Hippocrates, it was Aristotle who contributed most extensively to the development of biology. Important are his History of Animals and other works where he showed naturalist leanings, more empirical works that focused on biological causation and the diversity of life. Aristotle's successor at the Lyceum, wrote a series of books on botany that survived as the most important contribution of antiquity to the plant sciences into the Middle Ages. Scholars of the medieval Islamic world who wrote on biology included al-Jahiz, Al-Dīnawarī, who wrote on botany, Rhazes who wrote on anatomy and physiology.
Medicine was well studied by Islamic scholars working in Greek philosopher traditions, while natural history drew on Aristotelian thought in upholding a fixed hierarchy of life. Biology began to develop and grow with Anton van Leeuwenhoek's dramatic improvement of the microscope, it was that scholars discovered spermatozoa, bacteria and the diversity of microscopic life. Investigations by Jan Swammerdam led to new interest in entomology and helped to develop the basic techniques of microscopic dissection and staining. Advances in microscopy had a profound impact on biological thinking. In the early 19th century, a number of biologists pointed to the central importance of the cell. In 1838, Schleiden and Schwann began promoting the now universal ideas that the basic unit of organisms is the cell and that individual cells have all the characteristics of life, although they opposed the idea that all cells come from the division of other cells. Thanks to the work of Robert Remak and Rudolf Virchow, however, by the 1860s most biologists accepted all three tenets of what came to be known as cell theory.
Meanwhile and classification became the focus of natural historians. Carl Linnaeus published a basic taxonomy for the natural world in 1735, in the 1750s introduced scientific names for all his species. Georges-Louis Leclerc, Comte de Buffon, treated species as artificial categories and living forms as malleable—even suggesting the possibility of common descent. Although he was opposed to evolution, Buffon is a key figure in the history of evolutionary thought. Serious evolutionary thinking originated with the works of Jean-Baptiste Lamarck, the first to present a coherent theory of evolution, he posited that evolution was the result of environmental stress on properties of animals, meaning that the more and rigorously an organ was used, the more complex and efficient it would become, thus adapting the animal to its environment. Lamarck believed that these acquired traits could be passed on to the animal's offspring, who would
National Autonomous University of Mexico
The National Autonomous University of Mexico is a public research university in Mexico. It ranks in world rankings based on the university's extensive research and innovation. UNAM's campus is a UNESCO World Heritage site, designed by some of Mexico's best-known architects of the 20th century. Murals in the main campus were painted by some of the most recognized artists in Mexican history, such as Diego Rivera and David Alfaro Siqueiros. In 2016, it had an acceptance rate of only 8%. UNAM generates a number of strong research publications and patents in diverse areas, such as robotics, computer science, physics, human-computer interaction, philosophy, among others. All Mexican Nobel laureates are either alumni or faculty of UNAM. UNAM was founded, in its modern form, on 22 September 1910 by Justo Sierra as a liberal alternative to its predecessor, the Royal and Pontifical University of Mexico. UNAM obtained its autonomy from the government in 1929; this has given the university the freedom to define its own curriculum and manage its own budget without interference from the government.
This has had a profound effect on academic life at the university, which some claim boosts academic freedom and independence. UNAM was the birthplace of the student movement of 1968, which turned into a nationwide rebellion against autocratic rule and began Mexico's three-decade journey toward democracy; the university was founded on 22 September 1910 by Justo Sierra Minister of Education in the Porfirio Díaz regime, who sought to create a different institution from its 19th-century precursor, the Royal and Pontifical University of Mexico, founded on 21 September 1551 by a royal decree signed by Crown Prince Phillip on behalf of Charles I of Spain and brought to a definitive closure in 1865 by Maximilian I of Mexico. Instead of reviving what he saw as an anachronistic institution with strong ties to the Roman Catholic Church, he aimed to merge and expand Mexico City's decentralized colleges of higher education and create a new university, secular in nature and national in scope, that could reorganize higher education within the country, serve as a model of positivism and encompass the ideas of the dominant Mexican liberalism.
The project unified the Fine Arts, Political Science, Engineering, Medicine and the National Preparatory schools. The new university's challenges were political, due to the ongoing Mexican Revolution and the fact that the federal government had direct control over the university's policies and curriculum; this opposition led to disruptions in the function of the university when political instability forced resignations in the government, including that of President Díaz. Internally, the first student strike occurred in 1912 to protest examination methods introduced by the director of the School of Jurisprudence, Luis Cabrera. By July of that year, a majority of the law students decided to abandon the university and join the newly created Free School of Law. In 1914 initial efforts to gain autonomy for the university failed. In 1920, José Vasconcelos became rector. In 1921, he created the school's coat-of-arms: the image of an eagle and a condor surrounding a map of Latin America, from Mexico's northern border to Tierra del Fuego, the motto, "The Spirit shall speak for my race".
Efforts to gain autonomy for the university continued in the early 1920s. In the mid-1920s, the second wave of student strikes opposed a new grading system; the strikes included major classroom walkouts in the law school and confrontation with police at the medical school. The striking students were supported by many professors and subsequent negotiations led to autonomy for the university; the institution was no longer a dependency of the Secretariat of Public Education. During the early 1930s, the rector of UNAM was Manuel Gómez Morín; the government attempted to implement socialist education at Mexican universities, which Gómez Morín, many professors, Catholics opposed as an infringement on academic freedom. Gómez Morín with the support of the Jesuit-founded student group, the Unión Nacional de Estudiantes Católicos fought against socialist education. UNAM supported the recognition of the academic certificates by Catholic preparatory schools, which validated their educational function. In an interesting turn of events, UNAM played an important role in the founding of the Jesuit institution in 1943, the Universidad Iberoamericana in 1943.
However, UNAM opposed initiatives at the Universidad Iberoamericana in years, opposing the establishment of majors in industrial relations and communications. In 1943 initial decisions were made to move the university from the various buildings it occupied in the city center to a new and consolidated university campus; the first stone laid was that of the faculty of Sciences, the first building of Ciudad Universitaria. President Miguel Alemán Valdés participated in the ceremony on 20 November 1952; the University Olympic Stadium was inaugurated on the same day. In 1957 the Doctorate Council was created to organize graduate studies. Another major student strike, again over examination regulations, occurred in 1966. Students forced the rector to resign; the Board of Regents did not accept this resignation, so the professors went on
