Patterns of leaf carbohydrate partitioning and nodule activity in soybean plants grown under natural conditions and the irradiance level required to produce sufficient carbohydrate to obtain maximum rates of apparent N(2)-fixation (acetylene reduction) were measured. Soybean plants, grown outdoors, maintained constant levels of leaf soluble sugars while leaf starch pools varied diurnally. When ...

OBJECTIVE To determine the levels of sound to which infants are exposed during routine transport by ambulance, aircraft, and helicopter. DESIGN Sound levels during 38 consecutive journeys from a regional level III neonatal intensive care unit were recorded using a calibrated data logging sound meter (Quest 2900). The meter was set to record "A" weighted slow response integrated sound levels, ...

There are two methods for evaluating noise exposure in the workplace: dosimetry using a Personal Sound Exposure Meter (PSEM) and sampling using a sound level meter (SLM). This paper discusses the advantages and disadvantages of both methods in the context of the fundamental objectives of an occupational noise survey, i.e. identification of exposed workers, determination of exposure magnitude, a...

OBJECTIVE To compare measurements of the peak expiratory flow rate taken by the mini Wright peak flow meter and the turbine spirometer. DESIGN Pragmatic study with randomised order of use of recording instruments. Phase 1 compared a peak expiratory flow type expiration recorded by the mini Wright peak flow meter with an expiration to forced vital capacity recorded by the turbine spirometer. P...

This study is related to the POM - Measure 2 - Project B15 'Veterinary services computerization and technical support to livestock farms', in which innovative plants solutions has been introduced to recognize the single animal to measure the quantity of produced milk, to centralize and automate the management, in different cow and sheep and goats breedings in Puglia and Basilicata regions. The ...

Mesophyll cells from leaves of cowpea (Vigna unquiculata [L.] Walp.) plants grown under saline conditions were isolated and used for the determination of photosynthetic CO(2) fixation. Maximal CO(2) fixation rate was obtained when the osmotic potential of both cell isolation and CO(2) fixation assay media were close to leaf osmotic potential, yielding a zero turgor pressure. Hypotonic and hyper...

In order to make use of analysis and low noise design techniques one requires a knowledge of the noise performance of circuit elements, circuits and complete systems in order to determine whether they meet the specifications or not. Also to judge the effort of noise decreasing procedures in circuits one need to be able to measure the noise level. If high precision noise measurement is required ...
