One of key factors at the vibration reliability support of turbo-sets in operation – a correct design of journal bearings, and also the assurance of supporting system normal operation during a life cycle of a unit with possibility to control basic technical parameters characterizing a technical state. To solve this problem first of all a method for the permanent control of gaps in bearings and also static and dynamic forces affecting every bearing is required. In accordance with new RSS 55263-2012 gaps and shaft misalignments are to be controlled with the aid of two couples of shaft sensors for every supporting bearing. For the evolvement of forces affecting bearings it is necessary to solve the equations of lubrication in supporting bearings. In this work there is offered a method which allows carrying out all hydro-dynamic computations in advance. In the mode of real-time for the forces definition it is offered to use the interpolation on ready computation results. To realize this task there are formed fields of possible movements (FPM) of shaft journals in each bearing taking into account single geometrical peculiarities and actual gaps. In the FPM there is formed a grid and for every grid node a computation of essential static and dynamic characteristics is carried out, and the results are saved in a database. In a real-time mode according to the known position of a journal in a gap one defines a point in the FPM and essential characteristics are interpolated. In such a way are calculated all necessary characteristics of a bearing: vertical and horizontal loads, loss power for friction, mean temperature of lubrication in a lubricating oil wedge, a minimum gap, stiffness and damping coefficients. This information of a bearing state is necessary for the diagnostics of a technical state of a turbo-set, and it is impossible to obtain with the aid of common means of control existing at an electric power station. In the paper there is shown an example of FPM formation and a computation of basic static characteristics for an elliptical bearing throughout the entire field of possible movements. The analysis of the influence of gaps deviations from nominal values defined by repair lists is presented. The notion of the field of possible movements is introduced beyond which one diagnoses an abnormal mode of a turbo-set operation characterized by increased temperatures of lubricant or babbit and/or grazes. The methods for the computation of slider bearing characteristics throughout the whole of the field of possible movements with the possibility of smooth interpolation are developed for the application in the real-time diagnostic system of COMPAX

Corporate Spin-Offs and Capital Allocation Decisions
Authors: Feldman Emilie R.
Published: December 2016

This paper investigates how spin-offs affect capital allocation decisions in diversified firms. The sensitivity of capital expenditures to investment opportunities, representing the efficiency of capital allocation decisions, improves when firms undertake spin-offs. The improvement in the efficiency of capital allocation decisions is most pronounced immediately following the completion of spin-offs (though it attenuates thereafter) and in companies that operate in a moderate (as opposed to a high or a low) number of businesses pre-spin-off. Together, these findings uncover a novel benefit that is associated with spin-offs, an improvement in the process by which managers allocate capital in the divesting firms. These results also suggest that an important theoretical mechanism that may be driving this improvement is that spin-offs enable managers to devote more attention to the capital allocation process within their remaining businesses.

Published: December 2016

In 1993 a preliminary survey was conducted in the Hospital of Gonesse to examine pressure sore prevalence. The averages obtained showed that 5.4% of patients in hospital suffer from pressure sores. This prompted a further investigation involving 12 050 patients: 5.2% were found to have pressure sores. Patients with pressure sores were significantly older (76.4±14 years) than the average age of patients in the study, and 42% of pressure sores were found in patients with neurological pathology. The majority of patients (57%) had a single pressure sore. Most were grade I lesions (38%). The greatest number of pressure sores were found on the medium and long-stay wards. A nationwide complementary survey is now being undertaken to confirm these overall results.

Published: December 2016

The phrase ‘moist wound healing’ is frequently used to describe a desirable environment for wound care. It also appears in manufacturers' literature as an important feature of certain modem wound dressings. The reference quoted is almost invariably George Winter's paper, published in 1962.
Moist wound healing: critique II

Published: December 2016

I guess most nurses have not read Winter's original paper. I had not read it until recently, although it has been widely cited in textbooks and journal articles. A search of the Science Citation Index reveals more than 100 citations. At first glance, the paper appears insubstantial, considering the importance of its finding that epithelialisation occurs more quickly under moist wounds than dry wounds, and that, at day three, wet wounds have a greater covering of epithelialisation than dry wounds.

Guinea pig anaesthesia — how can risks be reduced?
Authors: Edis Abigail
Published: December 2016

Veterinary nurses should be competent at helping to anaesthetise all patients presented in first opinion practice and this includes small mammals. Although guinea pigs are still commonly seen in the veterinary practice and as pets, there is much concern with regards to anesthetising them, even for routine procedures. With a few considerations however, the risk of placing these patients under general anaesthesia can be reduced somewhat. Understanding the species' basic needs and potential disease status will reduce stress to staff and risk to the patient.

Published: December 2016

In this study, polyols recycled from decomposed polyurethane (PU) foam wastes were used in preparing adhesives for plywood manufacturing. A polyol was made from chemically decomposed flexible PU foam wastes separated from automobile shredder residue. The recycled polyol was mixed with a commercial polyol at weight ratios of 100/0, 25/75, 50/50, 25/75, and 0/100, respectively. These polyol mixtures were mixed, respectively, with polymeric methylene diphenyl diisocyanate at isocyanate group–to–hydroxyl group (NCO/OH) molar ratios of 1.0, 1.25, and 1.5 to prepare adhesives. The recycled polyol and adhesives were characterized by Fourier transform infrared spectroscopy. Plywood specimens bonded by the adhesives were fabricated and tested. The effects of NCO/OH molar ratio and recycled polyol–to–commercial polyol weight ratio on adhesive gel time and bonding strength before and after water treatments were evaluated. The adhesives prepared from recycled polyol presented shorter gel time and greater dry bonding strength than those prepared from commercial polyol. The adhesives prepared from the recycled polyol–commercial polyol weight ratio of 50/50 and NCO/OH molar ratio of 1.25 showed the best bonding performance after cyclic boiling water treatment. Multilinear regressions showed that NCO/OH molar ratio was the main factor in developing plywood shear strength.

The use of shading has been widely used for production of seedlings, flowers and ornamental plants, aiming to minimize the damage from the excess of luminosity. This research evaluated the effect of different shaded environments [0% (full sun); 35% and 50% of shading and overlapping screens of 35%+50%] on morphophysiological aspects and growth of Heliconia psittacorum cv. Golden Torch and Heliconia bihai cv. Humilis in Bom Jesus county, Piaui state, Brazil, from August, 2012 to July, 2013. The experiment was carried out in a completely randomized design with treatments arranged in a 2 x 4 (Species x Shading) factorial, with six repetitions. Plants of H. bihai cv. Humilis showed higher leaf area compared to H. psittacorum cv. Golden Torch when the corresponding overlapping screens of 35% + 50% was applied, indicating that the two species have different morphological mechanisms for adaptation in shaded environments. Plants grown in full sun (0% of shade) presented lower growth (height and leaf area) and lower chlorophyll content. The 50% of shading providedwas effective to achieve the desired establishment and growth of H. bihai cv. Humilis and H.Psittacorum cv. Golden Torch, grown in pots.

Published: December 2016

Mainz pouch II is a reliable and viable technique of continent urinary diversion. Patients are at increased risk of long-term complications including urolithiasis of the upper urinary tract and reservoir. We report the case of a 67-year-old male with prior Mainz pouch II due to invasive bladder cancer treated for a large renal calculus. Percutaneous nephrolithotomy (PCNL) was successfully performed. Stone management in these type of patients is of increased interest due to existed “anatomical challenges” concerning the access and safety during the procedure. To our knowledge this is the first case of PCNL in a patient with Mainz pouch II that has been reported in the literature.
Influence of SNP mutations in FTO and LEP genes on body mass in bovine populations
Authors: ČERNOŠA Iva , PIRC Žan , RENČELJ Andrej
Published: December 2016

Body mass gain in a certain time period is one of the most important parameters in beef production. Some candidate genes, which have major impact on growth traits, are known from the literature, notably among them the FTO (fat mass and obesity-associated) and LEP (leptin) locus. In our experiment, we assessed the frequency of alleles at two polymorphic sites within the FTO gene (FTO6 and FTO10) and at polymorphic site in the LEP gene in a sample of Aberdeen Angus (AA) and Holstein Friesian (HF) breeds. In a larger sample, containing dairy and beef cattle breeds we tested the association of these three SNPs with the body mass gain in a 200-day period (between 165th and 365th day of age). In our material we could not confirm the linkage between two SNPs within the FTO locus, due to the existence of the region with high recombination rate between exon 5 and intron 5 in the FTO gene. We demonstrated significant impact of birth weight, breed and SNPs in the FTO gene on the growth. The effect of the polymorphic site within the LEP gene could not be confirmed.
Monitoring of procalcitonin but not interleukin-6 is useful for the early prediction of anastomotic leakage after colorectal surgery
Authors: Zielińska-Borkowska Urszula , Dib Naser , Tarnowski Wiesław , Skirecki Tomasz
Published: December 2016

Background:

Early recognition of patients who have developed anastomotic leakage (AL) after colorectal surgery is crucial for the successful treatment of this complication. The aim of this study was to assess the usefulness of the assessment of procalcitonin (PCT) and interleukin-6 (IL-6) levels in the prognosis of AL.

Methods:

This observational study included 157 patients who underwent major elective colorectal surgery. The most common indications for surgery were cancer and inflammatory bowel diseases. Serum samples were obtained directly before surgery (D0) and 1 day (D1) after surgery, and the relationships between the serum concentrations of PCT and IL-6 and development of AL were assessed.

Results:

In total, 10.2% of patients developed post-surgical infections due to AL. PCT levels on D1 were significantly higher in patients who developed AL [2.73 (1.40–4.62)] than in those who recovered without complications [0.2 (0.09–0.44)]. The area under the ROC curve for PCT on D1 was 0.94, 95% CI (0.89–0.98). The sensitivity and specificity of the prediction of an infection were 87% and 87%, respectively, for PCT on D1, which was higher than 1.09 ng/mL. The increase in PCT concentration between D0 and D1 was significantly higher in patients with AL (p<0.001). Patients who developed AL had higher concentrations of IL-6 on D1, but the difference was not significant (p=0.28).

Conclusions:

This study confirms that surgical trauma increases serum PCT concentrations and that the concentration of PCT on D1 can predict AL after colorectal surgery. However, IL-6 is not a good early marker for developing AL.
Mitochondrial cytochrome c oxidase is inhibited by ATP only at very high ATP/ADP ratios
Authors: Ramzan Rabia , Schaper Andreas K. , Weber Petra , Rhiel Annika , Siddiq Muhammad Saad , Vogt Sebastian
Published: December 2016

In the past, divergent results have been reported based on different methods and conditions used for enzymatic activity measurements of cytochrome c oxidase (CytOx). Here, we analyze in detail and show comparable and reproducible polarographic activity measurements of ATP-dependent inhibition of CytOx kinetics in intact and non-intact rat heart mitochondria and mitoplasts. We found that this mechanism is always present in isolated rat heart mitochondria and mitoplasts; however, it is measurable only at high ATP/ADP ratios using optimal protein concentrations. In the kinetics assay, measurement of this mechanism is independent of presence or absence of Tween-20 and the composition of measuring buffer. Furthermore, the effect of atractyloside on intact rat heart mitochondria confirms that (i) ATP inhibition occurs under uncoupled conditions [in the presence of carbonly cyanide m-chlorophenyl hydrazone (CCCP)] when the classical respiratory control is absent and (ii) high ATP/ADP ratios in the matrix as well as in the cytosolic space are required for full ATP inhibition of CytOx. Additionally, ATP inhibition measured in intact mitochondria extends in the presence of oligomycin, thus indicating further that the problem to measure the inhibitory effect of ATP on CytOx is apparently due to the lack of very high ATP/ADP ratios in isolated mitochondria.
Multiple Comparisons Using Composite Likelihood in Clustered Data
Authors: Azadbakhsh Mahdis , Gao Xin , Jankowski Hanna
Published: December 2016

We study the problem of multiple hypothesis testing for correlated clustered data. As the existing multiple comparison procedures based on maximum likelihood estimation could be computationally intensive, we propose to construct multiple comparison procedures based on composite likelihood method. The new test statistics account for the correlation structure within the clusters and are computationally convenient to compute. Simulation studies show that the composite likelihood based procedures maintain good control of the familywise type I error rate in the presence of intra-cluster correlation, whereas ignoring the correlation leads to erratic performance.

Gaseous Electrical Discharge-Induced Degradation of Organic Compound in Wastewater: UV Irradiation and Ozonation Effect
Authors: Mok Young Sun , Jo Jin-Oh , Woo Changsu
Published: December 2016

This study investigated the degradation of an organic compound (an azo dye, Acid Red 4) in a synthetic wastewater by using dielectric barrier discharge (DBD) tube comprised of a hollow quartz cylinder and a coaxial copper rod. The DBD tube was immersed in the wastewater that was connected to the ground electrode. When AC high voltage was applied to the copper electrode, the electrical discharge occurred inside the quartz cylinder to produce ultraviolet (UV) light and reactive species such as ozone. The photocatalytic degradation of the organic compound with the UV emitted from the DBD tube was carried out in the presence of aluminum meshes coated with titanium oxide. The system further comprised a gas diffuser that distributed the ozone-containing gas produced in the DBD tube into the wastewater, such that the organic compound were degraded by reacting with ozone. The contributions of the photocatalysis and the ozonation to the degradation were separately assessed, and then combined effect on the degradation was examined. The results clearly revealed that the present system capable of degrading the organic compound in two ways (DBD-induced photocatalysis and ozonation) was very effective for the treatment of the wastewater.

Published: December 2016

Improvement of stability for NO removal in dielectric barrier discharge (DBD) reactor by pulse applied voltage is described in this paper. Two different types of power supply are used to drive the DBD reactor. The ac type power supply produces a sinusoidal waveform at 10 kV in amplitude and 10 kHz in frequency. The pulse voltage of 10 kV is generated by a full-bridge type pulse modulator using insulated gate bipolar transistor (IGBT) switches. A duty factor of the pulse voltage is controlled in the range from 10 to 80% with a gate signal of the IGBT switches. A multipoint electrode is used in the DBD reactor for low voltage drive.

Authors: Ramirez J. H. , Zea H. R. , Cramer Thomas
Published: December 2016

Heterogeneous dark Fenton and photocatalytic degradation of azo-dye chrysoidin were studied using natural marmatite from a Colombian gold deposit as catalysts. Marmatite is composed of zinc sulfates, iron sulfates and iron oxides; due to this composition marmatite is an active material in the degradation of chrysoidin. Marmatite was characterized by SEM, XRD, BET and XRF. Experimental results allow concluding that the dye was oxidized (degraded) in both, heterogeneous Fenton and photo-catalyst reactions, using Marmatite as catalyst. The variables considered were solution pH, marmatite concentration, C

Published: December 2016

Reactive dyes are the most abundantly used in textile industry due to their high color fastness, wide color spectrum as well as low energy consumption. The presence of these dyes in effluent released into receiving waters has become a serious environmental problem not only related to their color but mainly because of the hazardous byproducts. An environmentally sustainable development policy in textile industry requires development of new technologies to reduce water consumption as well as negative environmental impact of discharged wastewater. Advanced oxidation processes (AOPs) are the most promising technology for decolorization and mineralization of wastewater contamination. This paper presents the results of ozonation, Fenton’s oxidation and H

Lignin Degradation Through A Combined Process of Ionizing Irradiation and A Biological Treatment
Authors: Estrella Raúl , Muñoz Florinella , Vasco Catalina
Published: December 2016

In this work, the degradation of lignin was studied through a combined process of ionizing irradiation and a biological treatment. For the irradiation stage, two options were tested at the beginning: a gamma irradiation from a Cobalt source at a dose rate of 0.4 kGy/h and a beta irradiation from a linear electron accelerator at a dose rate of 827 kGy/h, in both cases for a dose of 10 kGy. Through UV-visible spectrophotometric scanning, we found better results for the lignin degradation by the beta irradiation; therefore, five higher doses: 20, 30, 40, 50 and 60 kGy were tested. Spectrophotometry, infrared spectrometry and waste water analysis allowed to determine 60 kGy as the best dose. Finally, an anaerobic biological treatment was used for the subsequent degradation of lignin. It was carried out as a batch process that lasted approximately 11 days. The combined process enhanced the BOD

Aqueous Benzene Oxidation in Low-Temperature Plasma of Pulsed Corona Discharge
Authors: Kornev Iakov , Preis Sergei
Published: December 2016

Wastewaters polluted with non-biodegradable volatile organic compounds (VOCs), such as aromatic substances, present a growing problem meeting no adequately affordable technological response. Low-temperature plasma generated in the gas-phase pulsed corona discharge (PCD) presents competitive advanced oxidation technology in abatement of various classes of pollutants, although the process parameters, the pulse repetition frequency and the liquid spray rate, require optimization. The experimental research into aqueous benzene oxidation with PCD was undertaken to establish the impact of the parameters to the energy efficiency. The oxidation reaction was found under the experimental conditions to mostly proceed in the gas phase showing little influence of the pulse repetition frequency and the gas-liquid contact surface. Oxidation of benzene and, presumably, other volatile pollutants in the volume of PCD reactor compartment presents an effective strategy of aqueous VOCs abatement.

A modified hydrodynamic model for routing unsteady flow in a river having piedmont zone
Authors: Patowary Sudarshan , Sarma Arup Kumar
Published: December 2016

Existence of piedmont zone in a river bed is a critical parameter from among numerous variations of topographical, geological and geographical conditions that can significantly influence the river flow scenario. Downstream flow situation assessed by routing of upstream hydrograph may yield higher flow depth if existence of such high infiltration zone is ignored and therefore it is a matter of concern for water resources planning and flood management. This work proposes a novel modified hydrodynamic model that has the potential to accurately determine the flow scenario in presence of piedmont zone. The model has been developed using unsteady free surface flow equations, coupled with Green-Ampt infiltration equation as governing equation. For solution of the governing equations Beam and Warming implicit finite difference scheme has been used. The proposed model was first validated from the field data of Trout Creek River showing excellent agreement. The validated model was then applied to a hypothetical river reach commensurate with the size of major tributaries of Brahmaputra Basin of India. Results indicated a 10% and 14% difference in the maximum value of discharge and depth hydrograph in presence and absence of piedmont zone respectively. Overall this model was successfully used to accurately predict the effect of piedmont zone on the unsteady flow in a river.

Published: December 2016

Background:In this study, the effects of olmesartan therapy on asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), L-arginine and inducible nitric oxide synthase (iNOS) levels were investigated in patients undergoing cardiopulmonary bypass.

Methods:Patients were randomly allocated to two groups, control and olmesartan. Olmesartan was administered 30 mg once a day beginning from preoperative day 5 to postoperative day 28 and on operation day. Blood was drawn from all patients and ADMA, SDMA, L-arginine and iNOS levels were analyzed at six time points (T1: before anesthesia induction, T2: during cardiopulmonary bypass, T3: five min after the cross-clamp was removed, T4: after protamine infusion, T5: on postoperative day 3 and T6: on postoperative day 28).

Results:In the olmesartan treated group, iNOS levels exhibited significant decreases at T2, T3, T4, T5 and T6 time points compared with control group (p<0.001, p<0.05, p<0.001, p<0.01, p<0.05 respectively). ADMA levels were significantly lower in olmesartan treated group than in control group at T3, T4, T5 and T6 time points (p<0.05, p<0.05, p<0.05, p<0.01 respectively). SDMA levels at T2, T3 and T6 time points were higher in control group than olmesartan group. L-Arginine levels were significantly higher at T2 and T3 time points in olmesartan treated group than control group (p<0.001, p<0.01).

Conclusions:It was concluded that administration of olmesartan reduced plasma ADMA, SDMA, iNOS levels and enhanced L-arginine level in CPB time and it could reduce potential postoperative complications through reducing oxidative stress and inflammatory response in the postoperative period after coronary bypass surgery.
