In addition there are formal oral examinations in January and May : in January they only involve students who have either ( a ) missed three or more classes ( for whatever reason ) , or ( b ) failed to participate actively in group discussion , or ( c ) whose submission of written work has been inadequate ( work handed in more than a week late will be corrected but not given a grade ) . In addition , steep slopes facing away from the radar will either have a lower SNR , causing large errors in phase-difference determination , or will be in shadow , causing loss of data . And even northern Minnesota gardeners have a hardy option . He aims to develop an electronic microsystem to measure and separate tiny particles , less than a micrometre across , suspended in fluid . The School offers more than a wide range of study choices . Prof. Crozier estimates that it would take 5-10 years with backing from a commercial company to be able to have a caffeine-free coffee bean available commercially . For now , however , sanitation ( promptly removing and destroying fallen fruit and leaves ) , cultural practices designed to promote optimum tree health , and perhaps occasional physical or chemical intervention are all that is normally needed to obtain a satisfying crop in most years . In addition there are formal oral examinations in January for students who have either ( a ) missed three or more classes ( for whatever reason ) , or ( b ) failed to participate actively in group discussion , or ( c ) whose submission of written work has been inadequate ( work handed in more than a week late will be corrected but not give a grade ) . The importance of this is that there is no point in talking about Sustainable Development or even adopting policies to that end if we do n't have a way of measuring whether or not they are succeeding . However , it is currently possible to monitor levels of anaesthesia and obtain a waveform of the level induced , so that an important area of research with a vast commercial potential is to link a patient via appropriate sensors to a microchip which analyzes the waveform and apply feedback in order to maintain anaesthesia at the appropriate level and thus avoid a patient " wakening " . It is worth noting that deformation is likely to precede measurable seismic activity in many cases - - e.g ., a rock must be stressed before it fails - - suggesting that deformation changes may be the first indicator of an impending eruption . They used borehole strainmeters to track a packet of magma , detecting the deflation of a deep reservoir and the corresponding upward motion of the magma in a conduit , culminating in a surface eruption . We will now have a consultation period to determine how best to integrate this new accommodation with the rest of our Estate to the benefit of the University as a whole .
