At present there is no efficient device-level modeling technique that models the effect of process variation on resistive bridges. This paper presents a fast and accurate technique to model the effect of process variation on resistive bridge defects. The proposed model is implemented in two stages: firstly, it employs an accurate transistor model (BSIM4) to calculate the critical resistance of a bridge; secondly, the effect of process variation is incorporated in this model by using three transistor parameters: gate length (L), threshold voltage (V ℎ ) and effective mobility ( ), where each follow Gaussian distribution. Experiments are conducted on a 65-nm gate library (for illustration purposes), and results show that on average the proposed modeling technique is more than 7 times faster and in the worst case, error in bridge critical resistance is 0.8% when compared with HSPICE.

It is exported successfully to the bacterial periplasm and assembles into pentamers which retain the ability to bind to GM1 ganglioside. Native toxin epitopes are displayed and the molecule can be easily purified from periplasmic extracts of cells expressing the gene fusion. Although the protein carries the natural sequence of the heat-stable enterotoxin, it is greatly attenuated in toxicity. Systemic immunization of mice or oral administration of the fusion elicits antibody responses against both classes of E. coli enterotoxin.

The ovum recovery rate following intrauterine insemination at 48 h after progestagen pessary withdrawal was 63.8 and 53.4% for sedated and nonsedated control ewes, respectively. Following intrauterine insemination at 60 h the corresponding values for sedated and control ewes were 72.6 and 73.9%, respectively. The proportion of transferable quality embryos recovered was not affected by sedation but was improved by insemination at 48 h rather than 60 h after pessary withdrawal (100 vs 35.4%). Embryo survival following laparoscopic transfer to recipients from donor ewes inseminated at 48 h, with or without sedation was 38.8% (7/18) and 50% (7/14), respectively. Following intrauterine insemination of the donors at 60 h, the survival rate in recipients was reduced for embryos transferred from both the sedated and control ewes to 6.25% (1/16) and 36.3% (4/11). It is concluded that delaying the timing of intrauterine insemination relative to pessary withdrawal and the use of acepromazine maleate as a sedative at the time of insemination are deleterious to embryo development and subsequent viability.

After surface membrane removal and characterization, at least 13 labelled proteins were identified together with a large amount of labelled glycolipids, free fatty acids and phospholipids, especially phosphatidyl ethanolamine. Cationised ferritin has been used to stimulate surface membrane turnover of iodinated worms and the shedding of covalently bound 125I-counts used as an index of turnover. Finally worms have been iodinated before and after stimulation of membrane turnover in chemically defined media and the patterns of labelled proteins were compared.

Techniques that involved the separation of motile spermatozoa prior to centrifugation were found to yield sperm suspensions of highest quality. If the spermatozoa were centrifuged prior to isolation of the motile cells, sperm function was impaired. The detrimental effects of centrifugation were associated with a sudden burst of reactive oxygen species production by a discrete subpopulation of cells (characterized by significantly diminished motility and fertilizing capacity) that could be separated from normal functional spermatozoa on Percoll gradients. If unfractionated sperm suspensions were subjected to centrifugation, the reactive oxygen species generated by this subpopulation impaired the functional competence of normal spermatozoa in the same suspension. Assessment of the ability of the antioxidants, butylated hydroxytoluene, and vitamin E, to ...
