Some of the highest losses of nitrate to surface waters come from drained agricultural land. Given previous this article studied for Belgian farming conditions (i) the effect of subsurface drainage density on nitrate losses and (ii) the economics of nitrate emissions, using the nitrogen version of DRAINMOD (Brevé et al., 1997 a and b). DRAINMOD (Skaggs, 1997) was used to simulate the performanc...
Objective: This study aimed to assess the urethrovesical anastomotic leakage (UAL) and associated factors in patients who underwent robot-assisted radical prostatectomy (RARP) its effect on early continence. Material Methods: The data of 81 RARP between February 2017 June 2022 were evaluated this retrospective analysis. On seventh postoperative day, we performed a cystography determine whether ...
Professor Emeritus, Institute of Psychiatry, Psychology and Neuroscience, King’s College London, UK, [email protected] In this issue, three papers discuss the issue of the brain drain: of psychiatrists from Egypt and Nigeria, and of nurses from East Africa. They explore the complexities of professional migration and its impact on the health of populations in source and recipient countries; they a...
As the number of systems which offer annotations on digital documents increases, robust anchoring of annotations is a key challenge. It is especially important if the annotator lacks write-access to the document being annotated. For example, if someone makes an annotation on a web page today and the web page changes tomorrow, what happens to the annotation? One approach is simply to “orphan” th...
This paper highlights the extent of the brain drain in relation to human resources for health (HRH) that is currently challenging Kenya, and suggests strategies that have the potential to change current working environments and improve HRH retention rates. Governments in partnership with health professional bodies and regulators could improve the working conditions for psychiatrists and mental ...
AlGaN/GaN High Electron Mobility Transistors (HEMTs) with various gate lengths have been stepstressed under both onand off-state conditions. On-state, high power stress tests were performed on 0.17 lm gate length HEMTs and a single 5 lm spaced TLM pattern. Significant degradation of the submicron HEMTs as compared to the excellent stability of the TLM patterns under the same stress conditions r...
Static X-parameter (XP) models for RF power amplifiers (PAs), derived from both simulations and nonlinear vector network analyzer (NVNA) measurements, are investigated for the prediction of PA performance under dynamic signal conditions such as in envelope tracking (ET). The instantaneous AM-AM, AM-PM and PAE predictions of XP models extracted from simulation are compared under ET dynamic signa...
A complete electrical characterization of different types of GaAs field effect transistors at liquid nitrogen temperature is performed. The trapping-detrapping mechanisms on deep levels are particularly adressed and a method is proposed to circumvent the collapse phenomenom which otherwise limits the electrical performances. From these measurements a HEMT non-linear model is extracted and is fo...
