Performance indicators of organized cervical screening in Romagna (Italy)
(2003)The availability of published data from organized cervical screening programmes in southern Europe is scant. In the Italian area of Romagna, a first round of organized screening (based on a 3-yearly Pap smear for women ... -
Observations on the Low-Energy Limits for Metal-to-Ligand Charge-Transfer Excited-State Energies of Ruthenium(II) Polypyridyl Complexes
(Department of Chemistry, 2010)The 77 K emission spectral maxima of bis(bipyridine)ruthenium(II) complexes are found to approach a limit at energies below about 14 000 cm−1. There is also evidence for related low-energy excited-state limits in some other ... -
Simulation of nitrate distribution under drip irrigation using artificial neural networks
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2004-04)Accurate knowledge of nitrate distribution in the soil under fertigation through drip-irrigation systems is fundamentally important for system design and management. The determination of nitrate distribution through modeling ... -

An autonomous controller for site-specific management of fixed irrigation systems
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2005-09)Distributed irrigation control (DIC) for site-specific management and/or operation of fixed irrigation systems is easier to install and maintain as compared to centralized irrigation control (CIC), but requires multiple ... -
Effects of Electronic Mixing in Ruthenium(II) Complexes with Two Equivalent Acceptor Ligands. Spectroscopic, Electrochemical, and Computational Studies
(Department of Chemistry, 2010)The lowest energy metal to ligand charge transfer (MLCT) absorption bands found in ambient solutions of [Ru(NH3)4(Y-py)2]2+ and [Ru(L)2(bpy)2]+ complexes (Y-py a pyridine ligand and (L)n a substituted acetonylacetonate, ... -
Evaluation Of Methods For Estimating Daily Reference Crop Evapotranspiration At A Site In The Humid Southeast United States
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2004)Estimated daily reference crop evapotranspiration (ETo) is normally used to determine the water requirement of crops using the crop factor method. Many ETo estimation methods have been developed for different types of ... -
Metal-to-Metal Electron-Transfer Emission in Cyanide-Bridged Chromium−Ruthenium Complexes: Effects of Configurational Mixing Between Ligand Field and Charge Transfer Excited States
(Department of Chemistry, 2008)Irradiations of the transition metal-to-transition metal charge transfer (MMCT) absorption bands of a series of cyanide-bridged chromium(III)−ruthenium(II) complexes at 77 K leads to near-infrared emission spectra of the ... -

Modeling water balance components in relation to field layout in lowland paddy fields. I. Model development
(University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 1996-04)In this study, a water balance model applicable to lowland paddy fields was developed. The model inputs consist of irrigation supply, climatic data, soil parameters and layout dimensions. The model is formulated to simulate ... -
Laparoscopic versus open distal pancreatectomy in pancreatic tumours: a case–control study
(2010)Laparoscopic distal pancreatectomy has become an increasingly used procedure in the surgical treatment of benign or borderline cystic and endocrine tumours. The feasibility and safety of this technique is well known but ... -
