Solid-state nuclear track detectors such as CR-39 are used in the detection of charged particles and heavy ions. In this paper, effect two types chemical etching solutions on properties detector 400 µm thickness was studied. The involved calculation parameters which bulk etch rates () respectively well rate ratio (V), then comparing them for solution. We sets each piece dimensions . were irradi...

ANGUSJournal n September 2011 Breeder question No. 1 Which is more important when doing a bull BSE, measuring a bull’s scrotal circumference or evaluating the semen that he produces? Response: Scrotal measurements and semen characteristics are both important! This is proven by the change made in the Society for Theriogenology’s breeding soundness exam in 1992. The exam was changed from a numeri...

Recently, 211At has received increasing attention as a potential radionuclide for cancer radioimmunotherapy. It is a α-particle emitter, which is extremely effective against malignant cells. We demonstrate a method to verify the efficiency of 211At-labeled trastuzumab antibodies (211At-trastuzumab) against HER2 antigens, which has not been determined for radioimmunotherapy. A CR-39 plastic nucl...

The maximum impact of oil on bird fauna was recorded at the beaches of Clifton where Tasman Spirit Oil Spill (TSOS) took place. After the disaster, its crude oil spread over the feeding grounds of birds. The low bird diversity at Clifton was recorded. Most adverse effects were observed along the beaches of Clifton, Sea View and adjoining areas. Concentrations of polycyclic Aromatic Hydrocarbons...

Many viruses deliver their genomes into the host cell's nucleus before they replicate. While onco-retroviruses and papillomaviruses tether their genomes to host chromatin upon mitotic breakdown of the nuclear envelope, lentiviruses, such as human immunodeficiency virus, adenoviruses, herpesviruses, parvoviruses, influenza viruses, hepatitis B virus, polyomaviruses, and baculoviruses deliver the...

Recoiling nuclei from Cold Dark Matter (CDM) elastic scattering interactions with the constituent elements of some minerals may produce etchable damage tracks in the crystal structure. Present calculations show that in muscovite mica, CDM tracks from recoiling potassium atoms could be readily distinguished from others due to alpha-decays in the uranium and thorium chains. Under favorable condit...

The sequence of phosphoenolpyruvate carboxykinase (PEPCK) has been previously identified as a promising candidate for reconstructing Mesozoic-age divergences (Friedlander, Regier, and Mitter 1992, 1994). To test this hypothesis more rigorously, 597 nucleotides of aligned PEPCK coding sequence (approximately 30% of the coding region) were generated from 18 species representing Mesozoic-age linea...
