Published: April 2009

AbstractAfter hatchery‐reared salmonids are released into the wild, their survival and performance are frequently lower than those of wild conspecifics. Additionally, negative effects of hatchery fish on wild fish are cited as factors affecting the recovery of salmonid populations. Alternative hatchery rearing environments and release practices have been proposed to mitigate both problems. We investigated the postrelease growth, survival, habitat use, and spatial distribution of hatchery steelhead Oncorhynchus mykiss fry reared in conventional and enriched environments and compared their performance with that of naturally reared steelhead fry from the same parent population in two streams. Average instantaneous growth rates differed between streams but not among the three rearing groups. The survival of naturally reared fry was significantly greater than that of both types of hatchery fry (relative survival = 0.33) but did not differ between the conventional and enriched environments. Naturally reared fry grew and survived equally well regardless of the type of hatchery fry with which they were stocked. Supplementation increased fry population size in all stream sections but produced hatchery‐biased populations. Steelhead fry preferred pool habitat within stream sections, but pool use was affected by an interaction between rearing environment and stream. Hatchery fry had more clumped spatial distributions than naturally reared fry, which were affected by a significant interaction between rearing type and stream. Hatchery rearing type and stream had no effect on the spatial distribution of naturally reared fry. We conclude that (1) hatchery steelhead fry released in streams grow as well as naturally reared fry but do not survive as well, (2) enriched hatchery environments do not improve postrelease growth or survival, and (3) upon release, fry raised in enriched hatchery environments affect the growth and survival of naturally reared fry in much the same way as fry reared in conventional hatchery environments.

Abstract
Abstract-The aim of the present study was to develop a passive a bsorptive equilibrium sampler that would enable the determination of the concentrations of polar organic compound (POC) in water more efficiently than existing techniques. To this end, a novel plastic material, poly(ethylene-co-vinyl acetate-co-carbon monoxide) (PEVAC), was evaluated and the results were compared with an existing silicone-based passive absorptive equilibrium device. Seven compounds (imidacloprid, carbendazim, metoprolol, atrazin, carbamazepine, diazinon, and chlorpyrifos), a mixture of pharmaceuticals, and pesticides with a logarithmic octanol-water partition coefficient ranging from 0.2 to 4.77 were selected as model substances for the experiments. The results showed that six of the seven selected POCs reached distribution equilibrium within 4 d in the two materials tested. A linear relation with a regression coefficient of more than 0.8906 between the established logarithmic absorbent-water partition coefficient and the calculated logarithmic dissociation partition coefficient of the selected compounds in the two polymers was observed. The correlation between these two coefficients was within one order of magnitude for the compounds that reached equilibrium in the two polymers, which demonstrates that both materials are suitable for mimicking biological uptake of POCs. The PEVAC material showed an enhanced sorption for all selected compounds compared to the silicone material and up to five times higher enrichment for the most polar compound. Fluorescence analysis of the sampler cross-section, following the uptake of fluoranthene, and proof that the sorption was independent of surface area variations demonstrated that the PEVAC polymer possessed absorptive rather than adsorptive enrichment of organic compounds.
Extrusion of Endodontic Filling Materials: Medico-Legal Aspects. Two Cases
Authors: Santoro Valeria , Lozito Piercarlo , Donno Antonio De , Grassi Felice Roberto , Introna Francesco 
Published: April 2009

The Authors describe two cases of alleged malpractice due to overfilling. The aim of this article is to underline some medico-legal aspects regarding the quantity of extruded material which may be considered acceptable and the consequent damage to the patient.Two cases are presented here: In the first case, the dentist’s liability is clear due to excessive extrusion of endodontic material beyond the apical region combined with incomplete obturation of the canals. In the second case however, because two different dentists were involved, establishing the connection of causality between their work and the damage reported by the patient was not easy. This situation makes it difficult to establish the limits of potential responsibility, coupled with the complete absence of radiographic signs of periapical rarefaction and the small quantities of material beyond the apex. From a medico-legal point of view, a dentist may be held responsible for compensation and financial expenses of a patient for restoration of damage resulting from a dental procedure.Italian guidelines offer no indications as to when overfilling should be considered the result of a procedural error, or if it fits within the range labelled as “acceptable” and this gap offers extremely subjective interpretations of legal consultants. So, it would therefore be useful to adopt more precise qualitative/dimensional parameters, keeping in mind that the guidelines offer therapeutic recommendations and are not rigid protocols.
Comparison of a Multiple Daily Insulin Injection Regimen (Basal Once-Daily Glargine Plus Mealtime Lispro) and Continuous Subcutaneous Insulin Infusion (Lispro) in Type 1 Diabetes

Published: April 2009

OBJECTIVE
Insulin pump therapy (continuous subcutaneous insulin infusion [CSII]) and multiple daily injections (MDIs) with insulin glargine as basal insulin and mealtime insulin lispro have not been prospectively compared in people naïve to either regimen in a multicenter study. We aimed to help close that deficiency.

RESEARCH DESIGN AND METHODS
People with type 1 diabetes on NPH-based insulin therapy were randomized to CSII or glargine-based MDI (both otherwise using lispro) and followed for 24 weeks in an equivalence design. Fifty people were correctly randomized, and 43 completed the study.

RESULTS
Total insulin requirement (mean ± SD) at end point was 36.2 ± 11.5 units/day on CSII and 42.6 ± 15.5 units/day on MDI. Mean A1C fell similarly in the two groups (CSII −0.7 ± 0.7%; MDI −0.6 ± 0.8%) with a baseline-adjusted difference of −0.1% (95% CI −0.5 to 0.3). Similarly, fasting blood glucose and other preprandial, postprandial, and nighttime self-monitored plasma glucose levels did not differ between the regimens, nor did measures of plasma glucose variability. On CSII, 1,152 hypoglycemia events were recorded by 23 of 28 participants (82%) and 1,022 in the MDI group by 27 of 29 patients (93%) (all hypoglycemia differences were nonsignificant). Treatment satisfaction score increased more with CSII; however, the change in score was similar for the groups. Costs were ∼3.9 times higher for CSII.

CONCLUSIONS
In unselected people with type 1 diabetes naïve to CSII or insulin glargine, glycemic control is no better with the more expensive CSII therapy compared with glargine-based MDI therapy.
Theoretical determination of the favorable mechanism of the reaction between AlX and HX (X = Br, Cl, and F)
Authors: Cherkaoui Mustapha , Boutalib Abderrahim 
Published: April 2009

Abstract
The reaction mechanism between AlX and HX (X = Br, Cl, and F) have been characterized in detail using DFT as well as the ab initio method. The reaction yielding AlX3 and molecular hydrogen was calculated to be highly exothermic. The present calculations also show that the possible routes to the trihalides species start more favorable with the primary insertion product AlX2H than with the biadduct AlX(HX)2 one.
Long time properties of the evolution of an unstable state
Authors: Urbanowski Krzysztof 
Published: April 2009

Abstract
An effect generated by the nonexponential behavior of the survival amplitude of an unstable state in the long time region is considered. In 1957 Khalfin proved that this amplitude tends to zero as t → ∞ more slowly than any exponential function of t. This can be described in terms of the time-dependent decay rate γ(t) which, when considered with the Khalfin result, means that this γ(t) is not a constant for large t but that it tends to zero as t → ∞. We find that a similar conclusion can be drawn for a large class of models of unstable states for a quantity, which can be interpreted as the “instantaneous energy” of the unstable state. This energy should be much smaller for suitably larger values of t than when t is of the order of the lifetime of the considered state. Within a given model we show that the energy corrections in the long (t → ∞) and relatively short (lifetime of the state) time regions, are different. This is a purely quantum mechanical effect. It is hypothesized that there is a possibility to detect this effect by analyzing the spectra of distant astrophysical objects. The above property of unstable states may influence the measured values of astrophysical and cosmological parameters.

Modelling of green water ingress into holds of an open-top containership in its preliminary design phase
In this paper a method is presented of modelling the green water ingress into holds of open-top containership, which can be useful in the preliminary ship design phase. As a result of the research a mathematical formula which makes it possible to determine a minimum freeboard height with a view of as- low- as- possible occurrence rate of green water ingress into holds at given ship design parameters, was obtained. The research was carried out under assumption of constant ship hull dimensions. The design formula was elaborated by using a method based on a goal-oriented conceptual approach to formulation of design criteria, proposed by IMO. On the basis of the concept a deterministic scenario describing operational conditions of the ship in question, was assumed, and for the conditions the research was performed.

Finite element local analysis of wave slamming on offshore structure
Offshore platforms are exposed to waves slamming event. Waves hitting the columns with a high velocity are in many cases the design criteria for column structure. This paper focuses on the analysis of wave slamming on floating platform column. Significant for wave slamming pressure is load history, which is usually based on model test. Wave slamming loads were defined on all four walls of column to assess the worst place. For south wall of column three positions exposed to slamming loads between elevation 21.000 (SWL) and elevation 35.500 were checked. Dynamic analysis has been performed with nonlinear FEM program ABAQUS/explicit. The steel was modeled as an elastic-plastic material with isotropic hardening.

On the possible increasing of efficiency of ship power plant with the system combined of marine diesel engine, gas turbine and steam turbine, at the main engine - steam turbine mode of cooperation
This paper presents a concept of a ship combined high-power system consisted of main piston engine and associated with it: gas power turbine and steam turbine subsystems, which make use of energy contained in exhaust gas from main piston engine. The combined system consisted of a piston combustion engine and an associated with it steam turbine subsystem, was considered. An algorithm and results of calculations of the particular subsystems, i.e. of piston combustion engine and steam turbine, are presented. Assumptions and limitations taken for calculations, as well as comparison of values of some parameters of the system and results of experimental investigations available from the literature sources, are also given. The system's energy optimization was performed from the thermodynamic point of view only. Any technical - economical analyses were not carried out. Numerical calculations were performed for a Wärtsilä slow-speed diesel engine of 52 MW output power.

Comparative anthelmintics efficacy of whole korolla fruit (Momordica charantia) extract and ivermecÂ® pour on was evaluated in vitro and in vivo on adult Ascaridia galli of indigenous chicken. The total trial chickens (60) were divided equally into 3 groups; group A as control, group B treated with ivermecÂ® pour on @ 500 Î¼g/kg bwt by dropper through skin absorption for single dose and group C treated with 3% aqueous extract of korolla. Freshly prepared aqueous extract of the korolla fruit was performed as wormicidal properties against adult A. galli on in vitro and in vivo study. 3% aqueous extract of korolla fruit was treated as higher efficacy against A. galli. The live body weight was increased in chicken after treatment in group B and C respectively but in control group body weight was slowly decreased. TEC (million/cu mm), Hb (gm %) and PCV (%30 minutes) were increased significantly in chickens of treated groups whereas ESR was increased in control groups.

Characterization of <i>Salmonella</i> serovars in comparison with some enterobacteria by SDS-page analysis
Authors: Begum F , Adachi Y , Khan MSR 
Published: April 2009

Salmonella bacteria causes a wide variety of disease and disease syndrome in different animals, birds including human beings and remains as a serious problem with public health significance throughout the world. A suitable vaccine or suitable immunogen detection system is not yet still available. However, it is interesting to characterize of a common immunodominant surface protein from a wide variety of Salmonella serovars to get the protective measures of Salmonellosis. Salmonella surface protein characterization could be useful for development of protective measures against Salmonellosis and for analysis of the protein profile relationship among the Salmonella serovars. A common and immunodominant surface protein of Salmonella serovars was critically important. SDS-PAGE analysis during the period of January 2004 to December 2004 showed a target surface protein of 37.81 kDa among the 54 Salmonella serovars in comparison to some enterobactors. The protein profiles in SDS-PAGE of Salmonella serovars were not different among all Salmonella serovars examined in this study. In contrast to the protein band of 37.81 kDa in all serovars of Salmonella were compared and recorded with those of Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, and Enterobacter cloacae and were detected as 36.5 kDa. SDS-PAGE analysis showed different size of protein of Salmonella serovars and other tested enterobacters. However, it needs further investigation including Western blotting and 2-D PAGE analysis of the specific band of 37.81 kDa and 36.5 kDa protein.

Published: April 2009

In the present study, antioxidant potential of the methanol extract of the leaves of Mimusops elengi Linn. was evaluated by using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) scavenging assay, reducing power and total antioxidant capacity. The extract showed significant activities in all antioxidant assays compared to the reference antioxidant ascorbic acid in a dose dependent manner. In DPPH scavenging assay the IC50 value of the extract was found to be 43.26Î¼g/ml while the IC50 value of the reference standard ascorbic acid was 58.92 Î¼g/ml. Total antioxidant activity was also found to increase in a dose dependent manner. Moreover, M. elengi extract showed strong reducing power. These results suggest that Mimusops elengi may act as a chemopreventative agent, providing antioxidant properties and offering effective protection from free radicals.

Measurement of the tibial plateau angle in cats with and without cranial cruciate ligament rupture
Authors: Reese S. , Lorinson K. , Lorinson D. , Schnabl E. 
Published: April 2009

SummaryThe objective of the present study was to determine the tibial plateau angle (TPA) in cats without stifle pathology and to compare it with cats suffering from an isolated cranial cruciate ligament rupture. Mediolateral radiographs of the stifle were taken and the tibial plateau angle was measured based on the method previously described by Slocum and Devine (1983) for dogs. Three observers with different levels of experience evaluated the radiographs of all of the cats in this study. The mean tibial plateau angle measured by all three observers in the cats with a rupture of the cranial cruciate ligament (CCL) was 3.1° greater than in cats without stifle pathology. Neither gender, age, body weight nor degenerative joint disease had an influence on measurement results. The authors found an inter-observer variability of ± 5.3°. Hence it can be concluded that cats with cranial cruciate ligament rupture have a greater TPA, and this at least lends some credence to the possibility of higher TPA being a predis-posing factor for cruciate injury in this species.
The utilization of a synthetic bone void filler (JAX) in the repair of a femoral segmental defect

Published: April 2009

Summary
Objectives: Currently available synthetic void fillers are indicated for bony voids or gaps that are not intrinsic to the stability of the structure. Jax™ TCP (tricalcium phosphate) is an osteoconductive bioceramic fabricated into 4 mm granules with a unique interlocking form, promoting structural integrity while allowing bone in-growth. The objective of this study was to assess bone ingrowth using a large, critically sized, femoral defect.
Methods: A 5 cm segmental ostectomy was created in the mid-diaphysis of 16 adult ovine femora. A stainless steel intramedullary nail was introduced and locked with two proximal and two distal fully-threaded locking screws. Each defect was surrounded with a resorbable macroporous poly (L-lactide-co-D, L) lactide mesh acting as graft containment. Treatment groups (n=4) were as follows: 1) Empty defect; 2) Morselized cortical bone; 3) Cortical strut; 4) Jax TCP. Serial radiographs were taken postoperatively and at two, four and six months. Femora retrieved at necropsy (six months) underwent computed tomography for volumetric analysis followed by histological assessment of the biological response.
Results: Little bone was apparent in the empty defect group, whereas significant bone was evident in both autograft groups and the Jax TCP group. Three-dimensional CT reconstructions and volumetric analysis were in close agreement with the radiographic findings.
Clinical significance: Jax TCP bone graft substitute has been proven to be effective in the healing of a large, critically sized, contained segmental defect. The healing observed was superior to that of cortical struts and the new bone laid down had similar radio-opacity to autograft.
The effect of bending and twisting on the stiffness and strength of the 3.5 SOP implant
Authors: Ness M. G. 
Published: April 2009

SummaryLocking plates are becoming increasingly popular in veterinary orthopaedics. The SOP is a novel locking plate system, which can be contoured with 6° of freedom and which utilises standard bone screws. The purpose of this work was to investigate the mechanical consequences of contouring the 3.5 SOP plate to support the formulation of clinical guidelines. The implants were loaded in four point bending using an industry standard protocol. The uncontoured SOP was found to be significantly stiffer and stronger than the uncontoured 3.5 DCP. Bending, and to a lesser extent, twisting, diminished the SOP’s stiffness and strength but the contoured SOP remained at least as stiff and strong as the untouched DCP.
