Among the various techniques available, ultrasonic Lamb waves offer a convenient method of evaluating composite materials. Since the Lamb wave velocity depends on the elastic properties of a structure, an effective tool exists to monitor damage in composites by measuring the velocity of these waves. Lamb wave measurements can propagate over long distances and are sensitive to the desired in-pla...

the genetic parameters and (co) variance components of body weight at birth (bw), weaning (ww) and six months of age (bw6) and average daily gain (adg) pre and post-weaning of afshari sheep were estimated using restricted maximum likelihood (reml) methodology and animal model implemented in dfreml software. the likelihood ratio test (lrt) was used to compare the models. year of birth, age of mo...

Testosterone plays an essential role in sexual differentiation of the male sheep brain. The ovine sexually dimorphic nucleus (oSDN), is 2 to 3 times larger in males than in females, and this sex difference is under the control of testosterone. The effect of testosterone on oSDN volume may result from enhanced expansion of soma areas and/or dendritic fields. To test this hypothesis, cells derive...

in this study, the immunogenicity of three types of antigens (hydatid fluid, protoscolices and whole body of e. granulosus) was investigated in lambs by elisa. sixteen 4–6-month-old lambs of mixed sexes were divided into 4 groups of 4 lambs (three immunized and one control group). twelve lambs as immunized groups received 2 mg of hydatid fluid, protoscolices and whole body of e. granulosus ant...

the aim of this study was to analyze the effect of sex, season and year of birth on growth rate of biometric measurements and body weight gain of thoroughbred foals during first six months of life. 103 thoroughbred foals (53 colts and 50 fillies) from golejewko stud born between 2006 and 2008, were used in this study. thoroughbred foals born in winter months were characterized by significantly ...

Ewe performance was compared for five pure breeds of sheep (Finnsheep, F; Rambouillet, R; Dorset, D; Targhee, T; Suffolk, S) and the crosses in development of two maternal composite lines (C1 = 1/2F1/4R1/4D and C2 = 1/2F1/4T1/4S). The data involved 10,959 breeding season records of 4,219 ewes by 412 sires. Ewe production and the components (fertility, litter size, neonatal and preweaning lamb s...

OBJECTIVES To assess safety, tolerance and efficacy of liposomal amphotericin B (LAMB) in a large unselected series of paediatric cancer/haematopoietic stem cell transplantation (HSCT) patients requiring LAMB therapy. PATIENTS AND METHODS The study included 84 children and adolescents (median age: 11 years) who received 141 consecutive courses of LAMB for prophylaxis (32), empirical therapy (...

It is well known that harmonic bounded Gaussian beams undergo a transformation into two bounded beams upon reflection on a solid immersed in a liquid. The effect is known as the Schoch effect and can be found at the Rayleigh angle for thick plates and at the different Lamb angles for thin plates. Here, a study is made on the effect of pulsed Gaussian beams reflected on solids. It is found exper...

Records of mortality during the first year of life of 8,642 lambs from a composite population at the U.S. Meat Animal Research Center were studied using survival and logistic analyses. The traditional logistic approach analyzes the binary response of whether or not a lamb survived until a particular time point, thus disregarding information on the actual age at death. Survival analysis offers a...
