Radiative Habitable Zones in Martian Polar Environments (2005)
Cordoba-Jabonero, C., Selsis, F., Patel, M. R., Cockell, C. S.
The biologically damaging solar ultraviolet (UV) radiation (quantified by the DNA-weighted dose) reaches the Martian surface in extremely high levels. Searching for potentially habitable UV-protected...

The required compounds N-aryl-N'-(3-chloro-2-benzo[b]thenoyl)thioureas 1ak were prepared by condensing 3-chloro-2-benzo[b]thenoyl chloride with different arylamines using ammonium thiocyanate,...
An ultraviolet simulator for the incident Martian surface radiation and its applications (2005)
Kolb, C., Abart, R., Bérces, A., Garry, J.R.C., Hansen, A.A., Hohenau, W., ...
Ultraviolet (UV) radiation can act on putative organic/biological matter at the Martian surface in several ways. Only absorbed, but not transmitted or reflected, radiation energy can be...
The Beagle 2 environmental sensors: science goals and instrument description (2004)
Towner, M.C., Patel, M.R., Ringrose, T.J., Zarnecki, J.C., Pullan, D., Sims, M.R., ...
A suite of instruments on the Beagle 2 Mars lander was designed and built in order to investigate the environmental conditions at the landing site. The sensor suite was capable of measuring air...
Fulchignoni, M., Aboudan, A., Angrilli, F., Antonello, M., Bastianello, S., Bettanini, C., ...
We developed a series of balloon experiments parachuting a 1:1 scale mock-up of the Huygens probe from an altitude just over 30 km to simulate at planetary scale the final part of the descent of the...
A miniature UV-VIS spectrometer for the surface of Mars (2004)
Patel, M. R., Towner, M. C., Zarnecki, J. C., Leese, M. R., Davies, A., Husbands, A.
A miniature spectrometer is in the process of development for a future Mars mission, to measure the UV-VIS spectrum encountered at the martian surface. With an intended mass of ~100 g, the...
A close encounter with a terrestrial dust devil (2004)
Towner, M. C., Ringrose, T. J., Patel, M. R, Balme, M., Metzger, S. M., Greeley, R., ...
We report on an extremely well characterised encounter with a terrestrial dust devil, and its comparison with martian dust devils.
Patel, M. R., Bérces, A., Kolb, C., Lammer, H., Rettberg, P., Zarnecki, J. C., ...
The issue of the variation of the surface ultraviolet (UV) environment on Mars was investigated with particular emphasis being placed on the interpretation of data in a biological context. A UV model...
The Beagle 2 environmental sensors: intended measurements and scientific goals (2003)
Towner, M. C., Ringrose, T. J.im, Patel, M. R., Pullan, D., Sims, M. R., Haapanala, S., ...
The Beagle 2 lander, due for arrival on Mars in December 2003, carries an Environmental Sensors Suite to monitor the local meteorology and carry out simple dust and oxidant measurements. The suite is...
Ultraviolet radiation on the surface of Mars and the Beagle 2 UV sensor (2002)
Patel, M.R., Zarnecki, J.C., Catling, D.C.
In this paper a simple radiative transfer model for the transmission of UV to the surface of Mars is presented for the wavelength range 190–410 nm. The model accounts for the variable presence of...
Characterisation of the UV environment of the Beagle 2 landing site (2002)
A study of the UV environment of the Beagle 2 landing site has been carried out. An instrument to measure the UV flux is present on the lander, and this work serves to aid in the interpretation of...
Analysis of speed of a binary divider using a variable number of shifts per cycle (1978)
In a recent paper (1976), the analysis of a binary multiplier using a variable number of shifts per multiplication cycle was described. The method was based on a discrete time finite state system...
Analysis of speed of a binary multiplier using a variable number of shifts per cycle (1976)
Iterative binary multiplication can be speeded up by examining two or more bits of the multiplier in each cycle. Freeman (1967) has described an exact method for calculating the resultant gain in...
Using a fading procedure to increase fluid consumption in a child with feeding problems.
Patel, M R, Piazza, C C, Kelly, L, Ochsner, C A, Santana, C M
Stimulus fading was combined with differential reinforcement and extinction to increase intake of a calorie-dense fluid by a 6-year-old child with feeding problems. The fading procedure consisted of...

Hard, R C, Patel, M R, Keller, L M, Linna, T J
Host-versus-graft (HVG) syndrome is the fatal allogenic disease which develops in susceptible strains of inbred mice following their perinatal inoculation with related F1 hybrid spleen cells. Deaths...
A simple and rapid method is reported here for enriching murine spleen cells with natural killer (NK) function as assessed by short-term cytolysis assay of 51Cr-labelled YAC-1 lymphoma target cells....
Effect of mitral valvular regurgitation on transthoracic impedance cardiogram.
Schieken, R M, Patel, M R, Falsetti, H L, Lauer, R M
Mitral valvular regurgitation consistently modified the wave form of the first derivative of the transthoracic impedance cardiogram. The transthoracic impedance cardiogram was recorded in 23 control...
