The effect of antibiotics of the psychrophilic anaerobic digestion (PAD) of swine manure slurry in sequencing batch reactors (SBRs) was investigated. Six antibiotics, tylosin, lyncomycin, tetracycline, sulphamethazine, penicillin and carbadox, were individually added to the pig diet at their maximum prescribed level. Manure slurries collected from pigs receiving control and medicated diets were...

This note gives pointers to what I think might be a good set of papers to read in order to obtain a grounding in auction theory, at least as it applies to work on the automated design of double auctions.

early all Americans undergo a steady rise in blood pressure with age. Almost 25 percent 'cross the' line into hypertension, the techni. cal term for chronically high blood pressure. This condition, in turn, can silently contribute to heart disease, stroke and kidney failure and thus plays a part in some 500,000 deaths every year. For black Americans, the situation is even more dire: 35 percent ...

The common occurrence of adoption among birds and mammals presents evolutionary biologists with an explanatory challenge. The benefits to adoptees are self-evident, but the benefits to the adopter(s), the origin of the set of behaviours that constitute 'adoptive' behaviour, and the conditions for its spread in populations are not always clear. Explanations in terms of direct and indirect benefi...

By making use of modal logic techniques, the paper disentangles two semantically different readings of statements of the type X counts as Y in context C (the classificatory and the constitutive readings) showing that, in fact, ‘counts-as is said in many ways’.

We describe a method for detecting forged data that arise in multiple readings of a single variable when some of the reported values are not true readings but rather copies of one or two genuine values. The method exploits the fact that zero differences between pairs of readings will occur with large frequency in such forged data. The identification of those technicians in whose data zero diffe...

OBJECTIVES To clarify whether a shorter interval between three successive home blood pressure (HBP) readings (10 s vs. 1 min) taken twice a day gives a better prediction of the average 24-h BP and better patient compliance. DESIGN We enrolled 56 patients from a hypertension clinic (mean age: 60 +/- 14 years; 54% female patients). The study consisted of three clinic visits, with two 4-week per...

Wireless transmission of a patient’s electrocardiogram (ECG) signals can be used to reduce cardiac healthcare cost. However, wireless transmissions have high error rates due to radio interference. The ECG signal, where every second of data could mean abnormal patterns, cannot tolerate such losses. Due to this healthcare crisis, the ability for a device to remotely monitor a patient’s medication...

Taking an alcohol swab of a person's forearm and analyzing it using a spectrophotometer has been shown to be a reliable method for detecting the presence of sunscreen. The aims of this study were to determine if moisturizing lotions or other non-sunscreen products influence the absorbance readings from skin swabs in a controlled setting, and to establish the cutoff point in determining the pres...

The main goal of a data collection protocol for sensor networks is to keep the network’s database updated while saving the nodes’ energy as much as possible. To achieve this goal without continuous reporting, data suppression is a key strategy. The basic idea behind data suppression schemes is to send data to the base station only when the nodes’ readings are different from what both nodes and ...
