Grid-Based remotely sensed hydrodynamic surface runoff model using emissivity coefficient / Jurina Jaafar

The development of a hydrodynamic distributed model is designed to simulate discharge and water levels as a function of space and time. The development of the model strongly depends on the physical based parameters, examples of physical parameters that include roughness Manning’s n, hydraulic conductivity, soil depth, river geometry and the surface land cover. Most Malaysian catchments are not gauged, albeit or scarce discharge data is available and the difficulty to access and hard to obtain in situ site area information. These scenarios have brought an interest into this study to use satellite images in obtaining information of the ground surface from inference in a digital elevation model (DEM) and other information such as the land use characteristics. The processes of infiltration and overland runoff flows are complex phenomenon. Both interact on the soil surface on the ground at its own capacity. Since soil surface is the primary order that control the hydrological and hydraulic processes, the topographic of the land use sensed by the satellite is used to describe the spatial variations of the ground surface. In this study, a quantitative surface runoff estimation using the information of emissivity from the remotely sensing technique is developed for potential input representing the surface roughness. The process from the satellite information allows an optimal judgment to decide the most appropriate Manning roughness to be used in the simulation of surface runoff..

Proper construction and arrangement of modern landfill

S povećanjem broja stanovništva potrebno je pronaći održivi način gospodarenja otpadom. U ovom radu su prikazane osnovne komponente modernog odlagališta otpada, koje teže tom cilju. Primjenom mehaničko-biološke obrade otpada i tehnologije za dobivanje energije iz otpada, smanjuje se količina otpada koji će se odložiti na odlagalište i dobivaju se korisni produkti (npr. kompost, bioplin). Primjenom odlagališta u smislu bioreaktora, ubrzava se razgradnja organske tvari mikrobiološkom aktivnošću koja dovodi do brže stabilizacije odlagališta.As the population increases it is necessary to find sustainable waste management. In this paper fundamental components of modern landfill for sustainable waste management are presented. By using mechanical-biological treatment of waste and waste-to-energy technologies, the volume of waste which is disposed of is reduced and useful byproducts are derived from it (e.g. compost, biogas). By implementing a bioreactor landfill, the degradation of organic compounds by microorganisms is faster which leads to a quicker stabilization of the landfill

The basic aspect of partnership accounting

This article describes the basic aspect of partnership accounting. The first part of this paper aims to explain the characteristics of a partnership, types of partners and partnership, partnership agreement, and advantages and disadvantages of operating as a partnership. The second part of this paper discusses an accounting procedures for a partnership firms. It highlights the method of accounting for partnership capital and the final accounts to be prepared by a partnership firm. In any partnership firms, there may be changes in partnership. A partnership firm is possible to admit new partners into the firm and it is also possible for any partner to leave the firm due to death or retirement. The third part of this paper explains factors contributing to changes in a partnership and the steps to be taken by a partnership business to record for changes in a partnership. At the end of this paper, the writers discuss the accounting procedures for dissolution of partnership. It is hoped that this paper will serve as a beneficial input to partnership businesses

numerical model and consolidation interventions of palazzo della ragione in milan

Abstract Palazzo della Ragione, erected in 1233, represents one of the most ancient and relevant historic building of Milan. During the last century, the Palace suffered significant modifications, including the realization of an underground tunnel immediately near the foundations. Numerical analysis conducted with a FEM model were developed on the basis of some experimental tests. In particular, the diagnostic campaign performed in 1979, in which flat jacks and dynamic tests were applied, allowed to obtain useful information on the mechanical characterization of the masonry. In addition, the execution of some dynamic identification tests in 2017 returned the own frequencies of the building 40 years later. Before to work on the structural project, the autor verified the consistency between the structural response of the numerical model and the one of the real building, obtained by dynamic tests. Some consolidation interventions were realized on the wooden trusses of the cover, in order to restore either local and global safety situation, with respect to vertical and horizontal load
