Study Of Performance Of Vertical Drainage Well Construction From Polymer Materials, I.A. Akhmedov, Z.K. Mirkhasilova
Study Of Performance Of Vertical Drainage Well Construction From Polymer Materials, I.A. Akhmedov, Z.K. Mirkhasilova
Irrigation and Melioration
The article is devoted to the reconstruction and construction of vertical drainage wells. The use of vertical drainage wells is characterized by a decrease in the level of groundwater. The article presents data and typical regions of the use of vertical drainage wells.Also presented are mechanical, physical and chemical methods of well cleaning in practice. The information on the design and construction of vertical drainage wells is described. The analysis of corrosion resistance of vertical drainage well materials and their service life has been carried out. It is known that polymeric materials are resistant to corrosive environments. Using filters made …
An Innovative Seeder For Sowing Non-Loose Seeds Of Saxaul And Cherkez, E.T. Farmonov
An Innovative Seeder For Sowing Non-Loose Seeds Of Saxaul And Cherkez, E.T. Farmonov
Irrigation and Melioration
The main reasons for the absence of a seeder for mechanized sowing of non-loose seeds of fodder plants in deserts are analyzed in the article. The author has developed a technology for sowing non-loose seeds (saxaul and cherkez), which prevents clogging, crushing and breakage in the seeder hopper, and provides for uniform and stable sowing at a set rate and shallow depth over the entire field area without reducing the biological germination. An innovative seeder with a universal sowing unit is recommended. Field tests of the innovative seeder with the proposed universal sowing unit were conducted in February 2020, as …
High Performance Thermal Insulation: Silica Aerogels In Construction Technology, Matthew Giarrusso
High Performance Thermal Insulation: Silica Aerogels In Construction Technology, Matthew Giarrusso
Honors Theses
The United States is a world leader in the production and expenditure of energy, accounting for 18% of the total global energy consumption in 2016, 40% of which was used for the heating, cooling, and lighting of commercial and residential buildings. Currently, traditional air-based insulation products are being used in thicker and more numerous layers in an attempt to keep up with contemporary codes and standards. One promising alternative to traditional insulation is silica aerogel. With a remarkably low density and thermal conductivity, silica aerogel could save energy, space, and weight in new and retrofit structures. Silica aerogels are currently …

Facilities & Campus Services, Sustainable UMass and Campus Planning support sustainability and energy conservation initiatives by providing in-house resources to campus staff as well as designers and contractors working with the University. The UMass Amherst Green Building Guidelines provide a framework for approaching new construction and major renovation projects at UMass Amherst that are undergoing LEED certification by focusing the conversation on green building aspects that are most important to the campus. They are intended to be the beginning of a dynamic conversation between designers, environmental consultants and constructors, university stakeholders, and users of new high performance buildings.

The relatively high turnover of timber sleepers (crossties in a plain track), bearers (skeleton ties in a turnout), and transoms (bridge cross beams) is responsible for producing greenhouse gas emissions 6 times greater than an equivalent reinforced concrete counterparts. This paper presents an innovative solution for the replacement of aging timber transoms installed on existing railway bridges along with the incorporation of a continuous walkway platform, which is proven to provide environmental, safety and financial benefits. Recent developments for alternative composite materials to replace timber components in railway infrastructure construction and maintenance demonstrate some compatibility issues with track stiffness as …
