Sloping farmlands are the major sources of soil, water and nutrient losses in arid and semi-arid regions. Information about the impacts of different tillage practices on soil erosion, nutrient loss and crop nutrient uptake on the sloping farmland of semi- arid soil is, however, limited. This study was carried out to investigate the effects of tillage direction on soil, water, nitrogen and phosp...

One of the main objectives of the smart grid initiative is to enable bulk power transmission over long distance, with reduced transmission losses. Besides the traditional high-voltage alternating current (HVAC) transmission, with the advancement in power electronics, high-voltage direct current (HVDC) transmission is increasingly becoming important. One of the main factors impacting the transmi...

Recent upgrades to the nutrient budgeting programme Overseer that affect environmental outputs for deer farms include: the deer intake model, which can influence nitrogen leaching losses; phosphorus losses from areas affected by wallowing and fence-line pacing; and, the greenhouse gas emissions database. In addition, farm blocks within Overseer are tested as sub-catchments (e.g. a group of padd...

This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...

The objective of this study is to describe the methodology used to isolate the main voltage loss indicators through a simple and effective treatment of a current interrupt and current sweep. The voltage loss indicators are activation polarization, mass transport, and ohmic losses. The indicators for these losses are the Tafel slope, mass transport resistance and ohmic resistance respectively. T...

This paper surveys the major issues regarding the transferability of tax losses upon a change of control. Whether tax losses should be transferable or not depends upon whether or not the market for corporate control is efficient. If there are too few efficiency-enhancing takeovers, then takeovers should be "subsidized." If, on the contrary, there are too many takeovers (from an efficiency point...

  In spite of realizing more loss than expected and reserved provision in loaning process, some of our banks avoid recognizing the losses, through extension of the loan contracts and consequently do not shift the realized losses to their capital. With this in mind, the major objective of this study is to design a frame-work, through which we can explain the differences between the results of t...

We report the fabrication and accurate measurement of propagation and bending losses in single-mode silicon waveguides with submicron dimensions fabricated on silicon-on-insulator wafers. Owing to the small sidewall surface roughness achieved by processing on a standard 200mm CMOS fabrication line, minimal propagation losses of 3.6+/-0.1dB/cm for the TE polarization were measured at the telecom...

We develop a tractable model of realization utility that studies the role of referencedependent S-shaped preferences in a dynamic investment setting with reinvestment. Our model generates both voluntarily realized gains and losses. It makes specific predictions about the volume of gains and losses, the holding periods, and the sizes of both realized and paper gains and losses that can be calibr...
