Time reversal active sensing using Lamb waves is investigated for health monitoring of a composite structure. In the present work experiments were conducted on a glass/epoxy composite plates to study the time reversal behavior of A0 and S0 Lamb wave modes. PZT wafer sensors were surface bonded to the structure for generation and reception of the Lamb wave modes. Time reversal experiments were f...

The mathematical and physical properties of the Lamb vector divergence are explored. Toward this aim, the instantaneous and mean dynamics of the Lamb vector divergence are examined in several analytic and turbulent flow examples relative to its capacity to identify and characterize spatially localized motions having a distinct capacity to effect a time rate of change of momentum. In this contex...

Hemimelia as a congenital anomaly is a failure of development of extremities formation in embryonic period. This anomaly is defined as complete absence of the part of extremities and different forms were explained for hemimelia. Adactyly is an alternative name for transverse hemimelia and is a rare disorder in the most of animal species. A two months old male lamb with normal vital signs was re...

Two mutant strains of Escherichia coli have been isolated in which the cellular location of an outer membrane protein, the phage lambda receptor (the lamB gene product), is altered. These mutations were initially selected in a strain containing a lamB-lacZ fusion. In the parent strain the protein coded for by the hybrid gene is located, at least in part, in the outer membrane. In the mutants it...

INTRODUCTION Leishmaniasis is a parasitic disease transmitted by phlebotomine sandflies. Between 700,000 and 1.2 million cases of cutaneous leishmaniasis and between 200,000 and 400,000 cases of visceral leishmaniasis (VL), which is fatal if left untreated, occur annually worldwide. Liposomal amphotericin B (LAMB), alone or in combination with other drugs, has been extensively studied as VL tre...

Postmortem proteolysis in skeletal muscle and factors affecting this process were examined in pork, lamb and beef longissimus muscles (LM) to determine the cause of differences in meat tenderness among these species. Fat thickness differed among species in the following order: pork greater than beef greater than lamb. The following patterns were observed for rate of temperature and pH decline: ...

Antifungal prophylaxis for patients at high risk for aspergillosis is appealing due to the high morbidity and mortality of aspergillosis despite antifungal therapy (1–3). While voriconazole is a logical option, reports of breakthrough mucormycosis are a cause for concern (5). To identify alternative prophylactic strategies, we utilized our novel, inhalational model of pulmonary Aspergillus fumi...

We have studied the immunological relatedness of LamB proteins from a wide range of enterobacterial species, using antibodies directed against denatured Escherichia coli K12 and Klebsiella pneumoniae LamB proteins (LamBE.c. and LamBK.p., respectively), and anti-peptide antibodies directed against 10 distinct loops of LamB from E. coli K12 predicted to protrude either side of the outer membrane....
