The use of ultrasound as a tool in small animal reproduction has expanded from its initial role in the evaluation of pregnancy in the female to its current use in monitoring fetal development, timing gestation and predicting parturition, diagnosis and management of reproductive tract disease and in supplementing breeding soundness examinations. In fact, B-mode ultrasonography has become an indi...

Introduction Reproductive performance has greater impact on beef economic returns than does either growth rate or product quality (Trenkle and Wilham, 1977). In most cow-calf operations, females still conceive via the natural breeding bull (Godfrey and Lunstra, 1989). Thus the reproductive capabilities of bulls are of paramount importance. These capabilities are largely influenced by one or mor...

Nominal sets are a sets-based first-order denotation for variables in logic and programming. In this paper we extend nominal sets to two-level nominal sets. These preserve much of the behaviour of nominal sets—including notions of variable and abstraction—but they include a denotation for variables and meta-variables. Meta-variables are interpreted as infinite lists of distinct variable symbols...

There are many different analysis methods for evaluation of complicated socio-economic processes. Banks are important participants of the market. Soundness and stability of banks is difficult to assess because of their complicated internal business structure, intertwined cash flows and strong influence of market conditions on bank’s performance. Multi-criteria methods of evaluation are among ma...

Computer vision system evaluation faces problems stemming from high-dimensionality, difficulty in achieving statistical soundness, and genericity. In this paper, a new framework for computer vision system evaluation is introduced. This framework, when applied properly, can be used to evaluate, with statistical soundness, many different vision system components including scenes, sensors, and alg...

A comparison between two distinct levels of back fat thickness in open cows, females not becoming pregnant during the previous breeding season, was carried out order to evaluate their reproductive performance prior next natural mating a seasonal program. Thirty cows from season were divided evenly by age and (BFT) groups. HBFT (high ≥ 70 mm) LBFT (low ≤ mm), values statistically different group...

In this study, semen samples from 25 bulls that had passed a breeding soundness evaluation were analyzed for the presence or absence of a 31-kDa protein, known as fertility-associated antigen (FAA), on spermatozoal membranes. Eighteen bulls had FAA on sperm (FAA-positive) and seven were devoid of FAA on sperm (FAA-negative). A single ejaculate from each bull was extended and frozen with 25 to 3...
