The datasheet for the MCP9808 explains that the temperature is stored as two bytes (one word). The digital word is loaded to a 16-bit read-only ambient temperature register that contains 13-bit temperature data in two’s complement format. The other 3 bits (i.e. bits 7, 6 and 5 of the first byte) contain the alert temperature settings. Bit 4 of the first byte is the sign (i.e. positive or negative Celsius value). If bit 4 is 1, the temperature is negative. This is equivalent to saying that negative temperatures will be represented as 256 plus the numeric value of bits 3 to 0 of the first byte. The second byte of the word contains the 8 least significant bits of the ambient temperature.
In my next post, I will describe how to connect a 3V LCD screen instead of sending the temperature readings to the REPL. Then you will have a stand-alone digital thermometer which can be used, for example, as part of a weather station project, data logging, or for environmental control.

In February 2011 the University of Chicago Medical School distributed iPads to its trainee doctors for use when reviewing clinical information and images on the ward or clinics. The use of tablet computing devices is becoming widespread in medicine with Apple™ heralding them as "revolutionary" in medicine. The question arises, just because it is technical achievable to use iPads for clinical evaluation of images, should we do so? The current work assesses the diagnostic efficacy of iPads when compared with LCD secondary display monitors for identifying lung nodules on chest x-rays. Eight examining radiologists of the American Board of Radiology were involved in the assessment, reading chest images on both the iPad and the an off-the-shelf LCD monitor. Thirty chest images were shown to each observer, of which 15 had one or more lung nodules. Radiologists were asked to locate the nodules and score how confident they were with their decision on a scale of 1-5. An ROC and JAFROC analysis was performed and modalities were compared using DBM MRMC. The results demonstrate no significant differences in performance between the iPad and the LCD for the ROC AUC (p<0.075) or JAFROC FOM (p<0.059) for random readers and random cases. Sample size estimation showed that this result is significant at a power of 0.8 and an effect size of 0.05 for ROC and 0.07 for JAFROC. This work demonstrates that for the task of identifying pulmonary nodules, the use of the iPad does not significantly change performance compared to an off-the-shelf LCD.
Full Text Available This retrospective study presents a comparison of assessment results achieved by distancelearning students and classroom-based students undertaking the same module in a degree course. The purpose of the comparison is to provide some objective measurement of the quality of distance education in relation to conventional classroom-based education. The authors have selected three groups of students, who have all undertaken the same module in the B. Sc Health Studies degree programme offered by the University of Paisley. One group (in Paisley undertook their studies by means of conventional classroom-based education, the second (in Hong Kong by supported distance learning with face-to-face contact in the form of tutorials, and the third (in a geographically dispersed group in the United Kingdom and other countries by supported distance learning with no face-to-face contact. The results obtained by these three groups of students were analysed. Because of the differences in the size of the groups, the Kruskal- Wallis 1- Way Anova test was applied to validate the face value findings. The authors include findings from the literature comparing distance education with conventional education and from cross-cultural studies to present their data in context. Analysis of the assessment results showed that students from all three groups were successful in their studies, but the students studying by distance learning obtained significantly higher end-of-module results than their classroom-based colleagues. This latter finding reflects the conclusion that other investigators have reached In their discussion the authors identify educational, cultural and personal factors that may help to explain their findings. A limitation in the study is that it concerns only one module in the degree programme. The research now moves on to comparing students who have undertaken the whole degree programme by the means described
Six fungal-type cellulose binding domains were found in the genome of the coccolithophore Emiliania huxleyi and cloned and expressed in Escherichia coli. Sequence comparison indicate high similarity to fungal cellulose binding domains, raising the question of why these domains exist in coccolithophores. The proteins were tested for binding with cellulose and chitin as ligands, which resulted in the identification of two functional carbohydrate binding modules: EHUX2 and EHUX4. Compared to benchmark fungal cellulose binding domain Cel7A-CBM1 from Trichoderma reesei, these proteins showed slightly lower binding to birch and bacterial cellulose, but were more efficient chitin binders. Finally, a set of cellulose binding domains was created based on the shuffling of one well-functioning and one non-functional domain. These were characterized in order to get more information of the binding domain"s sequence-function relationship, indicating characteristic differences between the molecular basis of cellulose versus chitin recognition. As previous reports have showed the presence of cellulose in coccoliths and here we find functional cellulose binding modules, a possible connection is discussed.
