Contemporaneo e política
Lazarus, Sylvain;
Educa??o & Realidade , 2012, DOI: 10.1590/S2175-62362012000200004
Abstract: the article deals with the crisis of politics and of the contemporary as a result of a name capture from the state field. regarding politics, all the attempts since 1968 of reconstituting it away from the state, from the point of view of people and the interior of situations, are now over. there is also a reflection about the separate nature of the state and about the thinking of people and the forms of subjectivity. therefore, this text aims at evaluating the rupture of thinking using the thesis that the contemporary nature of the state as a separate state is incompatible with the thinking of people guided to the possible. the article searches, at the end, questions the anthropological discipline and what it can enunciate about the contemporary today.

Finite size effects on crack front pinning at heterogeneous planar interfaces: Experimental, finite elements and perturbation approaches
Sylvain Patinet,L Alzate,E Barthel,D Dalmas,D Vandembroucq,V Lazarus
Physics , 2015, DOI: 10.1016/j.jmps.2012.10.012
Abstract: Understanding the role played by the microstructure of materials on their macroscopic failure properties is an important challenge in solid mechanics. Indeed, when a crack propagates at a heterogeneous brittle interface, the front is trapped by tougher regions and deforms. This pinning induces non-linearities in the crack propagation problem, even within Linear Elastic Fracture Mechanics theory, and modifies the overall failure properties of the material. For example crack front pinning by tougher places could increase the fracture resistance of multilayer structures, with interesting technological applications. Analytical perturbation approaches, based on Bueckner-Rice elastic line models, focus on the crack front perturbations, hence allow for a description of these phenomena. Here, they are applied to experiments investigating the propagation of a purely interfacial crack in a simple toughness pattern: a single defect strip surrounded by homogeneous interface. We show that by taking into account the finite size of the body, quantitative agreement with experimental and finite elements results is achieved. In particular this method allows to predict the toughness contrast, i.e. the toughness difference between the single defect strip and its homogeneous surrounding medium. This opens the way to a more accurate use of the perturbation method to study more disordered heterogeneous materials, where the finite elements method is less adequate. From our results, we also propose a simple method to determine the adhesion energy of tough interfaces by measuring the crack front deformation induced by known interface patterns.
An Interesting Neonatal Abdominal Mass
J Lazarus
African Journal of Urology , 2010,
Abstract: We present the case of a neonate who was born with an antenatal ultrasound diagnosis of a cystic abdominal mass of uncertain origin. The diagnosis of pelviureteric junction obstruction (PUJO) was obscured by difficulty determining the origin of the extremely large cystic abdominal mass. Sonographically, the kidneys appeared relatively normal, creating a diagnostic dilemma – the hydronephrosis was almost exclusively in an extrarenal pelvis. Additionally, contralateral hydronephrosis secondary to the mass effect further confused the diagnosis. We discuss the differential diagnosis of neonatal cystic abdominal masses and review the literature of giant hydronephrosis. Key Words: Abdominal mass, neonate, diagnosis, ultrasonography, ureteropelvic junction obstruction
Have we Overtreated Children with Vesicoureteric Reflux?
J Lazarus
African Journal of Urology , 2010,
Abstract: Urinary tract infections (UTI) are the most common serious bacterial infections in young children. These UTIs have a high association with vesicoureteric reflux (VUR). The pathophysiology of VUR’s renal sequelae, its investigation and management is presently undergoing a reassessment. This review documents these changes focusing on compelling new data. With regard to the need for and benefit of imaging procedures in children with UTIs we present an algorithm for investigation that is tailored to the African context. The value of continuous antibiotic prophylaxis is questioned and the role of injectable ureteric bulking is discussed with reference to the Swedish Reflux Trial. Key Words: Vesicoureteric reflux, children, etiology, pathophysiology, investigation, managment
Short communication: Ureterocystoplasty using the lower pole ureter of a duplex kidney with preservation of ipsilateral renal function
J Lazarus
African Journal of Urology , 2012,
Abstract: We describe the case of a 9 year old boy with neurogenic bladder dysfunction who co-incidentally had a unilateral duplex kidney with Grade 5 vesico-ureteric reflux into a poorly functioning lower moiety allowing heminephrectomy and ureterocystoplasty with preservation of ipsilateral renal function.
Exciting times: Towards a totally minimally invasive paediatric urology service
J Lazarus
South African Journal of Surgery , 2011,
Abstract: Following on from the first paediatric laparoscopic nephrectomy in 1992, the growth of minimally invasive ablative and reconstructive procedures in paediatric urology has been dramatic. This article reviews the literature related to laparoscopic dismembered pyeloplasty, optimising posterior urethral valve ablation and intravesical laparoscopic ureteric reimplantation.
Professional and career issues in administrative medicine

Journal of Healthcare Leadership , 2009, DOI: http://dx.doi.org/10.2147/JHL.S7846
Abstract: ofessional and career issues in administrative medicine Perspectives (5358) Total Article Views Authors: Arthur Lazarus Published Date November 2009 Volume 2009:1(Default) Pages 1 - 5 DOI: http://dx.doi.org/10.2147/JHL.S7846 Arthur Lazarus Senior Director, Global Clinical Development, AstraZeneca Pharmaceuticals, Wilmington, DE, USA Abstract: Administrative medicine is not recognized as a medical specialty in the United States, but increasingly, management-trained physicians are being recruited to fill important roles in hospitals and the life sciences industry. While the opportunities may be substantial, physicians who are interested in pursuing an administrative career should be aware of the challenges embodied in the role of physician executive, such as job turnover, alienation from peers, and overcoming the “caducean ceiling.” Healthcare systems that are serious about transforming themselves must harness the energies of physicians as organizational leaders, and physicians who are equal to the task must supplement their medical training with training in business and management.
The Micropaleontological Reference Centers Network
David Lazarus
Scientific Drilling , 2006, DOI: 10.2204/iodp.sd.3.10.2006
Abstract: The Micropaleontological Reference Centers (MRCs)comprise large microfossil slide collections prepared from core samples obtained through the Deep Sea Drilling Project(DSDP) and Ocean Drilling Program (ODP). The MRCs have been maintained for three decades, largely as a volunteer effort by a global network of curators at more than a dozen institutions (Fig.1, Table 1). They were originallyintended to provide a permanent micropaleontological archive for the DSDP; however, as their geographic and stratigraphic coverage has increased they have become increasingly valuable for research and teaching. This article describes the MRCs and their current usage, identifi es the need to maintain and improve the accuracy of the microfossil taxonomy upon which most DSDP and ODP geochronologyis based, and cites the potential for the future use of the MRCs by the Integrated Ocean Drilling Program (IODP).
