Enterprise Zones in the Courts: Legal Challenges to State Economic Redevelopment Legislation

The declining state of our nation\u27s cities has been, and continues to be, a frequent source of news and fodder for political debate. Unemployment, urban blight, crime, and economic dislocation are just a few of the inner-city\u27s afflictions which occupy the American mind. A multitude of theories have been advanced in order to explain the persistence of urban deterioration, accompanied by an array of governmental attempts to reverse, or at least stem, the trend of inner-city decay

Ozone therapy – a rare and avoidable source of infectious pathology of the spine

Ozone therapy is considered by many as an effective therapy for spinal degenerative pathologies. Despite its possible favorable results, we present a series of serious infectious complications, clearly related to ozone therapy and their treatment. The authors discuss their results compared with the literature and advocate for prudence when recommending ozone therapy

Extensive spinal epidural abscess complicated with hydrocephalus

Spinal epidural abscess is a rare but severe infection requiring prompt recognition in order to have a favorable outcome and appropriate treatment, mainly surgical. We present one of the largest extensions of such abscess in literature, involving the whole spine. No surgical treatment was tempted due to the involvement of 19 levels but antibiotics. The evolution of the lesion was complicated with hydrocephalus, by mechanism of cervical block of CSF flow, and needed first external derivation and later ventriculo-peritoneal drainage

Antibiotic resistance of Enterobacteriaceae strains responsible for urinary tract infections

Catedra Microbiologie, Virusologie şi Imunologie, USMF „Nicolae Testemiţanu”, Secţia Urologie, SCAMU mun. ChişinăuThe aim of this retrospective study has consisted in analysing the resistance to antibiotics of the germs from the Enterobacteriaceae family involved in urinary infections. The ethiological spectrum of urinary tract infections was dominated by Escherichia coli species (62,69%), followed, with lower percenteges, by Proteus spp., Klebsiella spp. and Enterobacter spp. All the 42 isolated Enterobacteriaceae strains have presented different levels of resistance to antibiotics. The sensitivity to imipenem and meropenem was higher in all the analyzed strains. Scopul acestui studiu retrospectiv a constat în analiza rezistenţei la antibiotice a germenilor din familia Enterobacteriaceae implicaţi în infecţii urinare. Spectrul etiologic al infecţiilor tractului urinar a fost dominat de Escherichia coli (62,69%), urmat, cu un procent mai mic, de Proteus spp., Klebsiella spp. şi Enterobacter spp. Toate tulpinile izolate de enterobacterii au prezentat niveluri diferit de rezistenţă la antibiotice. O sensibilitate marcată a fost înregistrată faţă de imipenem şi meropenem la toate tulpinile analizate

Decompressive craniectomy. From option to standard: Part I

Authors intend an update to the theoretical and practical data on a seldom utilized technique but often considered as last therapeutically option, so the necessity to realize it correctly. The authors present the history, the physiopathology of the technique, the surgical steps and options, together with details on the complications, surgical indications

Study of natural and forced heat transfer coefficients on a vertical heated plate

Infrared thermography measurement technique is a methodology which detects infrared energy emitted from an object, converts it to temperature, and displays images of temperature distribution. It is a powerful non-invasive methodology for the analysis of surface temperature measurements. The infrared camera represents a truly two-dimensional transducer, allowing for considerably high accurate measurements of surface temperature maps even in the presence of relatively high spatial gradients. The infrared thermography measurement technique is used in this experimental study to estimate the heat transfer coefficient over a flat plate. The main objective of this study was to get insights about the heat transfer in solids and on solid surfaces and its quantitative measurement. An infrared camera was used to calculate the temperature distribution for the evaluation of the heat transfer coefficient. Two study cases were taken into account: a first case without any fluid jet is calculated, where natural convection over the plate emerges due to the buoyancy effect, and a second case where a circular air jet is impinged on the surface - in this case the forced convection heat transfer coefficient has been evaluated

Drop dispensing in a viscous outer liquid

The formation and detachment of Newtonian drops in viscous external liquids is investigated. A global analysis of two necking processes is presented in order to highlight the behavior of such thinning phenomena, when controlled either by inertia or by viscous effects. Moving detached droplets in an immiscible outer liquid were studied in terms of velocity and drop-travel distance. Theoretical predictions are proposed and compared with experimental data for the volume of the drop and for the subsequent dynamics that follow after detachment. Our investigations point out that the drop rapidly achieves constant velocity, the value of it being in a satisfactory agreement with the model. Both the influence of the flow rate and that of the material properties on drop volume are pursued

Investigation of Multiphase Flow in a Trifurcation Microchannel—A Benchmark Problem

The evolution of an interface between two immiscible liquids in a three-branch symmetric microchannel is numerically and experimentally investigated. The main goals of the paper are to correlate the numeric data with the experimental results for the tested flow case and to assess the quality of the VOF procedure to trace the interface using the Fluent commercial code. The focus of the experiments was to characterize the dynamics of the oil–water interface formed in the vicinity of the bifurcation, at the entrance in the main microchannel of 400 microns width and 50 microns height. The oil core surrounded by water is visualized and micro-PIV measurements are performed in water. Experimental results qualitatively and quantitatively confirm the 3D numerical simulations. We propose the present investigated flow as a benchmark case for the study of the interface in a branching microchannel geometry

Unforced Rayleigh instability of an immersed liquid jet

Motivated by the occurrence of the injection of liquids in various technical processes, we study the capillary instability of a liquid jet surrounded by another liquid. The study focuses on the natural developing Rayleigh instability, hence without an imposed perturbation. We also point out the influence of viscosity on the main drop diameter, resulted after jet breakup, and on the breakup length itself. Modifications brought by a decrease of the capillary nozzle are also emphasized for a particular case
