Book Description
Master's Thesis from the year 2018 in the subject Engineering - Mechanical Engineering, Junagadh Agricultural University (College of Agril Engineering & Technology), course: M.Tech Thesis, language: English, abstract: The objectives of this study are to develop a mini tractor mounted clod crusher, to evaluate the performance of the developed machine and to work out economics of the machine. In tillage tools used in India faces problem like, poor soil-tire interface, clod formation, compaction due to heavy traffic and timeliness in operation. Hence, it was planned to fabricate three different types of clod crusher and to evaluate its performance with clod crusher implements. To achieve this objective a prototype implement consisting of three different types of clod crusher cylinders’ like as square spike, round spike and spiral arrangement of spike were developed costing Rs. 7000/- per each cylinder. The newly developed implement was tested in field condition to evaluate its performance. Their performance results were analyzed in terms of tilling quality of soil and machine parameters. The effects of treatments on soil physical properties like soil bulk density, clod MWD were evaluated. Machine performance parameters like fuel consumption, field efficiency and cost of operation were also studied. Better performance in terms of tilling quality of soil was obtained using clod crusher (square spike) attachment to cultivator. The optimum values of clod MWD, clod crushing field efficiency and fuel consumption were found 13.64 mm, 78.37 % and 7.02 lit/ha respectively. The operating cost were found 882, 1050 and 988 ₹/ha in square spike, round spike and spiral arrangement respectively. Using clod crusher attachment to cultivator a farmer can save more rupees against another implement which is used for seed bed preparation.

Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Scholarly Research Paper from the year 2013 in the subject Pedagogy - Common Didactics, Educational Objectives, Methods, grade: -, Hooks Independend School Distict, language: English, comment: Ronnie Thompson, M.Ed. Currently serves as Superintendent for Hooks Independent School District in Hooks, Texas. Formally served as Assistant Superintendent for the Texarkana Independent School District in Texarkana, Texas. He has also served as Executive Director of School Improvement, Associate Principal, Assistant Principal, and a classroom teacher. He is an experienced teacher in the Career and Technology field and has served as an adjunct professor of education at Texas A&, M University-Texarkana. He has a total of 22 years of experience in education., abstract: The effectiveness of an Integrated STEM Professional Development Model for elementary teachers was evaluated in terms of students' perceptions of the classroom learning environment and student outcomes towards mathematics. The sample consisted of 664 grade 3 - 5 mathematics students from 41 mathematics classrooms. Students from a STEM focused elementary school (Morriss) provided 191 student responses with 473 student responses coming from 4 other elementary schools within the same school district. The students responded to a learning environment questionnaire based on three scales from the What Is Happening In this Class? (WIHIC) and the attitude scale from the Test Of Science Related Attitudes (TOSRA). Factor structure, internal consistency reliability, discriminate validity, and the ability to distinguish between different classes were supported by data analysis of Morriss and Other student groups. An ANOVA was used which produced statistically significant differences in the Cooperation scale. Morriss students' perceived higher levels of cooperation in their classrooms relative to Other students from schools within the same school district. Student outcomes (Achievement and Attitudes) showed a significant d
