or in Van Giesen picrofuchsin. As an instance typical of the ease of use and reliability of the stain, a series of slides was stained for different lengths of time in a trial lot of this solution which contained only 10 grams each of ferrous and ferric alum, instead of the 20 as above described. The slides were then counterstained with Van Giesen picrofuchsin (5 minutes) in the usual manner. Th...

In 1930 Delrue (1) reported that the isolated gastric mucosa of the frog, when mounted properly in a dual-chambered bath, will secrete acid and will respond to the addition of drugs. The same author subsequently demonstrated (2) the effects of varying the ionic composition of the artificial medium on the in vitro production of acid. The theoretical importance of this approach to the study of th...

Previously, using inelastic scattering of 240-MeV alpha particles at small angles with a deformed potential analysis, we reported @1# 32% of the E0 EWSR in two Gaussian peaks in Ni and argued that no more than 50% of the E0 strength was located between Ex512 and 25 MeV. Satchler and Khoa @2# carried out a folding analysis of our data and on that basis concluded the two peaks contained ;50% of t...

HE study reported in this paper concerns the effects of X-rays and thermal neuT trons on dormant seeds of the tomato, Lycopersicon esculentum, expressed as chromosomal abnormalities in root tip mitoses, seedling injury, and chlorophyll and morphological changes. XI and NI refer to the X-rayand thermal neutron-irradiated generations, respectively; Xz and Nz to the progenies of the XI and NI gene...

On the basis of studies of esophageal electrocardiograms the authors conclude that retrograde conduction to the atria from premature ventricular beats is common and that the theory of normal unidirectional block in the A-V node is not tenable. In most of the cases with retrograde conduction, the latter is not discernible in simultaneously recorded lead II, which explains why the phenomenon has ...

Abstract The biosensor technology has the potential to revolutionize aquaculture industry, but selection of tagging method, operational mode (stand-alone vs. wireless systems) and telemetry ultimately depends on life species, stage research question. In particular, AEFishBIT is a small stand-alone device composed tri-axial accelerometer, microprocessor, battery RFID tag that was designed be ext...

In this study electrical discharge process was used to increase surface wear resistance of pure aluminum. Pulse-on-time and pulse current were considered as input parameters of the electrical discharge process. Experimental results reveal that the electrical discharge process is a successful method for improving the surface wear resistance of aluminum, so that this method has greatly increased ...

The properties of nuclei far from stability provide a stringent test of the validity of shell model Hamiltonians derived from data for nuclei near the valley of stability. Failure of shell model calculations to extrapolate to nuclei far from stability may indicate a breakdown of symmetries assumed in the model. Such a breakdown may provide evidence for new regions of deformation as were found f...

The National Superconducting Cyclotron Laboratory (NSCL) is a national nuclear physics research laboratory on the campus of Michigan State University. In a typical experiment, heavy ions with masses ranging from hydrogen to uranium are created in an Electron Cyclotron Resonance (ECR) ion source and injected into the K500 cyclotron. The accelerated beam is transported to the K1200 cyclotron, whe...
