The Columbia River Project
No full textThe Columbia River is second in size when compared with other North American rivers, and is second only to the Mississippi. From the standpoint of the power development, it is the greatest of all American rivers. Its basin has an area of about 259,000 square miles. A volume of water averaging annually 199,850,000 acre-feet passes through The Dalles, Oregon. The Columbia River is approximately 1,200 miles in length, of which the upper 465 miles lies wholly in Canada. Of the portion in the United States, 425 miles lie above the mouth of the Snake River. From the mouth of the snake to the Pacific Ocean is 324 miles. The drainage area of the Columbia River above the mouth of the Snake River is 103,00 square miles, of which 39,000 square miles are in Canada and 64,000 square miles are in the United States. This area is divided between the Provine of British Columbia and three states of Montana, Idaho, and Washington
American short stories of the depression decade
No full textShort stories written before the depression decade of 1930 to 1940 were optimistic tales influenced by the period of speculation and inflation. The stories catered to the esthetic sense of the public, had obvious tendencies toward idealism and gentility, and comparatively little irony. Many were written with elaborate hauteur. The fact that nearly everyone in America was "sitting on top of the world" with plenty of money, having a gay, happy times, was reflected in these pre-depression stories
Three case studies of retarded Spanish-culture beginners, Edinburg, Texas, 1946-1947
No full textA major problem which now confronts education is how to achieve improvement in teaching children who have language difficulties. The Spanish-Culture child, whom Little found in almost every South Texas community (9,18) presents one of the most pressing problems in the present-day educational system because of his difficulty in mastering the English language. (8,118) This problem of inadequate language development of Spanish-Culture children has grown in importance in the minds of educational leaders, especially in Texas
Farm labor in the Lower Rio Grande Valley of Texas
No full textThe factors of food production are land, labor and capital. Of these three factors, labor is the controlling factor in the farm program of the Lower Rio Grande Valley of Texas This is true because of the nature and type of farming done in the valley. The production of fruits, vegetables and berries as well as cotton and grain require a maximum of hand labor due to irrigation, field harvesting, packing and processing
Story of Banquete, Texas: a background for the educational system
No full textThe purpose of this study has been to give something of the history of the region now known as Banquete, Texas. Comparatively little has been written of the early history of this section of Texas so rich in things of human interest and historical importance. Cabeza de Vaca passed through it four hundred years ago. La Salle and his Frenchmen visited the country and caused the Spanish to become active in exploring and settling in the Gulf region. Mexico came into possession of it after 1821. Texas and Mexico claimed it after 1836. General Taylor's army marched from Corpus Christi to the Rio Grande at the beginning of the Mexican War
Zona Gale: a study
No full textThe first phase of American regionalism on a nation-wide scale belonged to the latter part of the nineteenth century. It was characterized by a somewhat superficial, but romantic, portrayal of eccentric people who resided in remote, isolated sections of the country. About 1900 the second phase of regionalism, which was more objective and disillusioned in tone, made its appearance. It called for a re-examination of rural America in more critical light, and concerned itself with the social moral, and institutional factors in addition to the spectacular
The history and development of irrigation in the Lower Rio Grande Valley
No full textUntil the recent years the Rio Grande Plain, the southern part of which is called the Lower Rio Grande Valley, was almost completely isolated. To approach it from the Mexican cities to the south, or later from the American settled area on the north was a tedious, dangerous, overland journey which few people attempted. Over nearly all this region grew mesquite trees, which sent their root far down in search of moisture. Here, too, were found the chaparral, the Spanish dagger, and the prickly pear or cactus that made an almost impenetrable growth
The use of 2, 4-dichlorophenoxyacetic acid in the control of weeds and woody shrubs
No full textThe problem of weed and brush control is as old as agriculture itself. As the population increases, each generation find never more complex problems confronting them which must be solved if the pasture and field crops, our only source of food, are to be grown in the abundance which is necessary to feed the people of the world
Path planning algorithm for a two-wheel differential mobile robot in robot operating system
No full textThis thesis focuses on the algorithm used for navigation between two different locations by avoiding obstacles. The algorithm is developed in a way that results in an efficient path planner between two given locations. Algorithms such as the potential field approach and Voronoi diagram are used as references in developing the suggested algorithm by a hybrid approach to developing the performance of the proposed algorithm. Python is used to write a new path planner function for the algorithm developed under this research work. Navigation is achieved by integrating the proposed path planner to the open-source middleware called Robot Operating System (ROS). A custom robot is defined in the ROS ecosystem using the Unified Robot Description Format (URDF). Several launch files are created to launch the robot in the desired environment and launch the path planning algorithm in Gazebo. Localization is achieved using the open-source gmapping plugin in ROS. An occupancy grip map of the domain is obtained using RVIZ software with custom-built parameters of the laser attached to the robot. The proposed algorithm is then integrated into ROS by creating several nodes involving publisher-subscriber and server-client relations to make it available for the robot to receive information from its sensors and send velocity commands to navigate effectively. A prior map is provided for the path planner node in ROS to enable the robot to plan its desired line of the path towards the goal location. The desired line of the track is maintained in conjunction with real-time sensor readings. The frequencies of path planners are determined such that it enables a successful obstacle avoidance solution. The performance of the proposed algorithm concerning path length and execution time is weighed with some of the well-known algorithms. The kinematic and dynamic constraints of the differential mobile robot are not considered in this approach
The economic history of Klerberg County
No full textKlerberg County is located on the lower coastal prairies of Texas. It was created and organized in the 1913 from Nueces County by an act passed by the thirty-third legislature, and named for Robert Klerberg, a German emigrant who came to Texas in 1834 and fought in the Battle of San Jacinto with Houston.
