in this study 71 head of conceiving ewe and their progeny (91 head) from the flock of lori-bakhtiari sheep (360 head), in sholi station were randomly selected to determine the relationship between the immunoglobulin (igg) concentration in the ewe's serum and colostrum, and lamb's serum. ewe blood sample, colostrum of ewe and blood of the lamb was taken 2 weeks before parturition, 1 to 8 hours a...

We have characterized a nonlethal selection for mutations that allow Escherichia coli to grow on large maltodextrins (Dex+) in the absence of the lamB encoded maltoporin LamB. These Dex+ mutations occur before and after imposition of the selection and the selection does not result in a general increase in mutagenesis. The recovered Dex+ mutations are almost exclusively mutations that alter the ...

As continuous health monitoring of aircraft components will provide substantial time and cost savings to the aircraft industry, the use of an integrated sensing technology with autonomous damage assessment is looked for. This study is part of the 6 STREP framework AISHA project, investigating the use of ultrasonic Lamb wave technology for the fast inspection of large shell structures. For the d...

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...

Mutant Escherichia coli strains in which export of the LamB protein (coded for by the lamB gene) to the outer membrane of the cell is prevented have been described previously. One of these mutant strains contains a small (12-base pair) deletion mutation within the region of the lamB gene that codes for the NH2-terminal signal sequence. In this mutant strain, export but not synthesis of the LamB...

Due to the problems of dispersion and multi-modes overlap for ultrasonic Lamb wave propagation, it is difficult to use it in many fields, such as long-range inspection. After ultrasonic Lamb waves are generated by a broadband ultrasonic pulse, these problems make the wave packets to spread out and various modes overlap in both time and space domain as they propagate through a plate or pipe. It ...

Abstract   Case Description- A three-day-old male Kordi lamb had a soft painless fluctuating mass on the mid-parietal region, with no clinical signs except difficulty in standing; was referred to the clinic. Clinical Findings- Clinical examination revealed a normal body temperature, a heart rate, a respiratory rate, and inability to stand without any congenital defects Three-dimensional comp...

Reproductive efficiency is a crucial factor in the economic viability of small ruminant exploitation. In spite this, few producers utilize available reproductive technologies related to hormonal interaction, which are vital for sustainability their operations. Therefore, this review aimed investigate potential effects alterations and hormone interactions during pregnancy lactation determine adv...

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 (...
