Ito Films

A study on the resistance of directly sputtered films and treated films of Indium Tin Oxide (ITO) is done to initiate an extensive study on the material. This study involves variation in terms of number of layers and duration of deposition. Treated films are produced by undergoing annealing process which is carried out using Split Type Tube Furnace. Resistance measurements were carried out using Semiconductor Parametric Analyzer (SPA). Results show that the directly sputtered ITO films produced lower resistance compared to the treated ITO films.

Preliminary Study

The aim of this study was to determine whether asymptomatic small ruminant lentivirus seropositive (SRLV-SP) goats were more susceptible to bacterial infection of the udder when lactating by comparing the presence and species of pathogenic bacteria in their milk with the values for seronegative goats (SRLV-SN). Milk samples were collected during morning milking on days 20, 40, 60, 150, and 210 of lactation for three consecutive years and subjected to bacteriological examination. Staphylococcus caprae and S. xylosus were the most frequent strains identified in both SRLV-SP and SRLV-SN goats. The prevalence of pathogenic bacteria was the highest in the 1st lactation, regardless of SRLV status. Moreover, the prevalence of pathogenic bacteria was significantly higher in SRLV-SP goats, but only those in the 5th or further lactation (p = 0.010). This suggests a relationship between long-lasting SRLV infection and susceptibility to bacterial infections of the udder.

Preliminary Study

Brucellosis is a bacterial disease that causes elk and bison to abort and may have potential to be transmitted to domestic cattle. In this preliminary study we examined how long healthy bovine fetuses remained in the environment and could be available for contact by elk, bison, or cattle. Healthy bovine fetuses were placed on state elk feedgrounds, the National Elk Refuge, and Grand Teton National Park to simulate an elk or bison aborted fetus. Fetuses were monitored until they disappeared due to scavenging. Ninety percent of the fetuses disappeared from the National elk refuge within 31 hours, but it took 163 and 130 hours for fetuses to disappear from state feedgrounds and Grand Teton National Park, respectively. We found, via analysis of covariance, that there was a significant difference in fetal disappearance rates depending on where the simulated abortions occurred. We also found that aborted fetuses could potentially serve as a source of bacterial infection for several days. This preliminary study will be expanded to include greater numbers of animals and additional locations in coming seasons.

<p>Investigation of pathogenic bacteria and its inhibitor on grouper culture in some places of Lampung Bay had been carried out. Six strains of pathogenic bacteria and 28 strains of inhibitior bacteria were found in grouper and its habitat.  By inhibition test, 4 strains inhibited pathogenic bacteria were obtained. Inhibition test for <em>Vibrio harveyi </em>had also been performed using a bacterial collection of Marine Microbiology Laboratory of Research Center of Oceanography-LIPI.  The result showed that 3 strains could be used against bacterial infection.

Hormonal Therapies

A preliminary study of human mammary carcinoma on the ultrastructural level is reported for a metastatic, subcutaneous nodule, obtained as a surgical biopsy. The patient's tumor had responded favorably to a series of hormonal therapies, including androgens, estrogens, progestins, and corticoids for recurring nodules over eight years. The pertinent nodule was removed from the region of the gluteal maximus, two weeks following stilbestrol therapy. It was about 1.5 cms in diameter, and was located within the dermis. Pieces from it were fixed immediately in cold fixatives: phosphate buffered osmium tetroxide, glutaraldehyde, and paraformaldehyde. Embedment in each case was in Vestopal W. Contrasting was done with combinations of uranyl acetate and lead hydroxide.
