O rio Pardo está localizado nos estados de Minas Gerais e Bahia no Brasil, sendo importante manancial para o desenvolvimento da região. O presente estudo utilizou a técnica de regionalização de vazões baseada em regressões múltiplas para estimativa de vazões máximas com diferentes períodos de retorno, vazão média de longa duração e vazões mínimas com 90% (Q90) e 95% (Q95) de permanência para a região baiana da bacia hidrográfica do rio Pardo. Constatou-se que a região em estudo pertence a uma única região homogênea, tendo a área de drenagem e comprimento total da rede de drenagem como as variáveis de melhor correlação. Dentre os modelos de regressão testados para o rio principal, o tipo potencial foi o que apresentou melhores resultados para as vazões máximas estudadas, média de longa duração e mínima com 90% de permanência (Q90). Para vazão mínima com 95% de permanência (Q95), o modelo exponencial foi o que apresentou melhores resultados. Nos afluentes, a inexistência de estações fluviométricas limitou a aplicação do método da conservação de massas apenas a modelos de regressão do tipo linear, todavia, o método se mostrou eficiente na estimativa de vazões afluentes, permitindo a continuidade nos valores de vazão.

Zusammenfassung
Reorganisationen internationaler Unternehmensgruppen bergen oftmals reichlich steuerliches Konfliktpotential, in Deutschland insbesondere auch aufgrund der komplexen Funktionsverlagerungsvorschriften. Neben der schieren Komplexität der deutschen Vorschriften sind es vor allem viele ungeklärte Rechtsfragen, die für Unsicherheit bei Steuerpflichtigen sorgen. Die neueste Rechtsprechung klärt einige davon, gleichwohl bleiben, wie der vorliegende Beitrag aufzeigt, immer noch erhebliche Unwägbarkeiten für Unternehmen bestehen, die sich insbesondere auch aus den inzwischen geänderten Rechtsgrundlagen ergeben.

Published: July 2017

AbstractThe precipitation of cadmium sulfide nanoparticles is induced on the surface of Escherichia coli, and the biological hydrogen production efficiency under visible light (VL) irradiation is investigated. When endogenous [Ni–Fe]‐hydrogenase is anaerobically induced, an additional 400 µmol of hydrogen gas is generated within 3 h from the hybrid system suspension (50 mL) under VL irradiation (2000 W m−2), corresponding to an increase in hydrogen production of ≈30%. The apparent quantum efficiencies of the hybrid system under 470 and 620 nm VL irradiation are 7.93% and 9.59%, respectively, which are higher than those of many photoheterotrophic bacteria. Furthermore, the mechanism of the enhanced hydrogen evolution is investigated. The interaction between photogenerated electrons and cells of E. coli is confirmed by heat‐treatment, electron‐scavenger, and separation studies. The acceleration of pyruvate generation, inhibition of lactate fermentation, increase of formate concentration, stimulation of hydrogenase activity, and elevation of nicotinamide adenine dinucleotide (NAD)H/NAD ratio in the hybrid system are responsible for the enhanced hydrogen production. A feasibility study is also conducted using wastewater and natural sunlight for the hydrogen production by the hybrid system. An additional 120 µmol of hydrogen is generated from the hybrid system within 3 h under these conditions using natural resources.
Aerosol‐Jet‐Assisted Thin‐Film Growth of CH3NH3PbI3 Perovskites—A Means to Achieve High Quality, Defect‐Free Films for Efficient Solar Cells

Published: July 2017

AbstractA high level of automation is desirable to facilitate the lab‐to‐fab process transfer of the emerging perovskite‐based solar technology. Here, an automated aerosol‐jet printing technique is introduced for precisely controlling the thin‐film perovskite growth in a planar heterojunction p–i–n solar cell device structure. The roles of some of the user defined parameters from a computer‐aided design file are studied for the reproducible fabrication of pure CH3NH3PbI3 thin films under near ambient conditions. Preliminary power conversion efficiencies up to 15.4% are achieved when such films are incorporated in a poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate‐perovskite‐phenyl‐C71‐butyric acid methyl ester type device format. It is further shown that the deposition of atomized materials in the form of a gaseous mist helps to form a highly uniform and PbI2 residue‐free CH3NH3PbI3 film and offers advantages over the conventional two‐step solution approach by avoiding the detrimental solid–liquid interface induced perovskite crystallization. Ultimately, by integrating full 3D motion control, the fabrication of perovskite layers directly on a 3D curved surface becomes possible. This work suggests that 3D automation with aerosol‐jet printing, once fully optimized, could form a universal platform for the lab‐to‐fab process transfer of solution‐based perovskite photovoltaics and steer development of new design strategies for numerous embedded structural power applications.

Published: July 2017

CasesSeptic cardiomyopathy is defined as a reversible left ventricular systolic dysfunction. Patients with severe septic cardiomyopathy have a high mortality rate, even if they receive conventional therapy. For those patients, previous reports showed intra‐aortic balloon pump (IABP) efficacy. We report two rare cases with IABP introduction leading them to drastic improvement, and survival from severe septic cardiomyopathy. Case 1 is a 78‐year‐old woman diagnosed with renal calculus pyelonephritis, septic shock, and septic cardiomyopathy. Case 2 is a 62‐year‐old man diagnosed with pneumonia, septic shock, and septic cardiomyopathy.OutcomeIn both cases, despite conventional therapy for cardiomyopathy, including high‐dose catecholamine therapy, shock was not reversed, and the IABP was inserted. Circulatory status was improved after the introduction of the IABP.ConclusionOur findings suggest that an IABP can be useful for salvaging patients with septic cardiomyopathy who do not respond to conventional therapy.

Published: July 2017

AbstractA novel transformation is reported for the reaction of terminal or internal alkynes with the nitrene precursor PhI=NTs (Ts=p‐toluenesulfonyl) in the presence of catalytic amounts of TpBr3Cu(NCMe) (TpBr3=hydrotris(3,4,5‐tribromo‐pyrazolylborate). Two products containing an imine functionality have been isolated from the reaction mixtures, identified as sulfinamides and isothiazoles. The former correspond to the formal reduction of the sulfone group into sulfoxide, whereas the latter involves the insertion of an alkyne carbon atom into the aromatic ring of the N‐tosyl moiety.

Published: July 2017

ABSTRACTPolyurethane foams were prepared by using functional quaternary ammonium monomers to endow the porous materials with antimicrobial properties. For this purpose, tri‐ and tetra‐hydroxyl functional quaternary ammonium compounds were synthesized and used as a triol and tetraol monomer in a polyurethane foam formulation. By this method, the cationic ammonium group is chemically incorporated into the polyurethane backbone. Polyurethane foams containing different amounts of the quaternary ammonium functional group were prepared and characterized by means of Fourier transform infrared spectroscopy, carbon solid‐state nuclear magnetic resonance, and scanning electron microscopy. The antimicrobial properties of the cationic polyurethane foams were evaluated toward Escherichia coli and Staphylococcus aureus Gram‐negative and Gram‐positive bacteria, respectively. Polyurethane foams containing more than 20% of quaternary ammonium component display high antimicrobial activity and can be used for several applications requiring antimicrobial properties. © 2017 Wiley Periodicals, Inc.

Salmon calcitonin‐loaded PLGA microspheres/calcium phosphate cement composites for osteoblast proliferation
Authors: Wu Ruixue , Ma Bin , Zhou Qiang , Tang Cui 
Published: July 2017

ABSTRACTTo improve the efficacy of salmon calcitonin (SCT) on disuse osteoporosis‐induced bone fracture, the sustained‐release vehicles delivered to bone fractures should be developed. In this study, SCT‐loaded poly(d,l‐lactic‐co‐glycolic acid) microspheres (SCT‐PLGA MS) with 20 kDa‐COOH and 40 kDa‐COOH (SCT‐PLGA‐20 COOH MS and SCT‐PLGA‐40 COOH MS) are incorporated into calcium phosphate cement (CPC) at various mass ratios. The cumulative release and mechanical properties of SCT‐PLGA MS/CPC composites decrease as PLGA MS/CPC mass ratio increase. Scanning electron microscopy images and the mass loss of composites indicate the MS from 20% SCT‐PLGA MS/CPC composites have mostly degraded after 8 weeks. In addition, SCT released from the 20% SCT‐PLGA‐20 MS/CPC composites significantly facilitate proliferation and differentiation of MC3T3‐E1 cells. In conclusion, 20% SCT‐PLGA‐20 COOH MS/CPC composites exhibit the sustained drug release, proper CPC degradation, good mechanical properties, and preferable osteoblast proliferation, which would be beneficial to their in vivo applications. © 2017 Wiley Periodicals, Inc.

Testing the exclusion capabilities and durability of the Sharksafe Barrier to determine its viability as an eco‐friendly alternative to current shark culling methodologies

Published: July 2017

Abstract

Following a shark attack, local governments often rapidly respond by implementing indiscriminate shark culls. These culls have been demonstrated to have substantial localized and adverse effects on a variety of marine organisms, and therefore there is an increasing need for an eco‐friendly alternative that maximizes both beachgoer and marine organismal safety.
In response to such culls, the novel magnetic barrier technology, the Sharksafe Barrier was developed and rigorously tested on a variety of sharks implicated in shark attacks (e.g. bull sharks – Carcharhinus leucas and white sharks – Carcharodon carcharias). Although these studies exhibited promise in shark swim pattern manipulation and C. leucas exclusion, research was lacking in assessing if the technology could serve as an alternative to shark nets, or more specifically, if it could exclude motivated C. carcharias from bait.
Using a 13 m × 13 m square exclusion zone, this study aimed to test the C. carcharias exclusion capabilities of the Sharksafe Barrier while additionally assessing the long‐term structural integrity of the system.
After 34 trials and approximately 255 hours of total video collected over two years, data illustrate that all interacting C. carcharias were successfully excluded from the baited Sharksafe Barrier region, whereas teleosts and other small elasmobranch species were not. In addition, the long‐term deployment potential of this barrier system held promise owing to its ability to withstand harsh environmental conditions.
Therefore, with the successful exclusion of a second large shark species, C. carcharias, from a baited region, continued long‐term research and implementation of this system at other locations should be considered to assess its viability and overall success as a bather and shark protection system.
Tourism impact on stream fish measured with an ecological and a behavioural indicator

Published: July 2017

Abstract

As nature‐based tourism grows, its impacts on aquatic ecosystems follow, requiring effective management techniques to conserve river integrity. Nevertheless, strong indicators of tourism impacts are scarce and have seldom been studied for many species.
This study evaluated whether microhabitat use and activity period of a variety of fish species are effective for assessing tourism impacts in a headwater stream in which recreation (snorkelling) occurs. Microhabitat use and activity period of the most representative fish were observed in river stretches used for recreation and compared with reference stretches.
Fish neither altered microhabitat use nor became more cryptic owing to tourism, maybe because they have evolved to occupy a certain microhabitat and cannot inhabit others, thus making habitat use a poor indicator of tourism impact.
Fish respond to the presence of tourists by changing the promptness to begin and end activity, making the time of activity a good indicator of tourism impact, which can be easily assessed by tourism managers or government agencies and used to control the environmental impact of recreation involving fish.
It is suggested that aquatic conservation protocols should include local indicators, and that behavioural indicators (activity period) might be more relevant than ecological indicators (microhabitat use) for early recognition of tourism impacts. These findings can be extended to the conservation of other fish communities subject to intensive tourism and with a strong circadian rhythm, such as coral reef fishes.

AbstractRab proteins are small monomeric GTPases/GTP‐binding proteins, which form the largest branch of the Ras superfamily. The different Rab GTPases are localized to the cytosolic face of specific intracellular membranes, where they function as regulators of distinct steps in membrane trafficking. RabX4 is an insect‐specific Rab protein that has no close homolog in vertebrates. There is little information about insect‐specific Rab proteins. RabX4 was expressed in Escherichia coli and subsequently purified. Antibodies against Bombyx mori RabX4 were produced in rabbits for western immunoblotting and immunohistochemistry. Western blotting of neural tissues revealed a single band, at approximately 26 kD. RabX4‐like immunohistochemical reactivity was restricted to neurons of the pars intercerebralis and dorsolateral protocerebrum in the brain. Further immunohistochemical analysis revealed that RabX4 colocalized with Rab6 and bombyxin in the corpus allatum, a neuronal organ that secretes neuropeptides synthesized in the brain into the hemolymph. RabX4 expression in the frontal ganglion, part of the insect stomatogastric nervous system that is found in most insect orders, was restricted to two neurons on the outer region and did not colocalize with allatotropin or Rab6. Furthermore, RNA interference of RabX4 decreased bombyxin expression levels in the brain. These findings suggest that RabX4 is involved in the neurosecretion of a secretory organ in Bombyx mori.

AbstractThis present study was designed to investigate the pharmacokinetic profiles and tissue distribution characteristics of clevidipine and its primary metabolite H152/81 in rats following a single intravenous administration of clevidipine butyrate injectable emulsion. For this study, a sensitive and selective liquid chromatography–tandem mass spectrometry (LC–MS/MS) method was established and validated for the simultaneous quantitation of clevidipine and H152/81 in rat whole blood and various tissues. A Hedera ODS‐2 column with two gradient elution programs was employed for the troubleshooting of matrix effect on the detection of analytes among different biological samples. The experimental data showed that clevidipine represented quick elimination from blood with a half‐life of about 4.3 min and rapid distribution in all of the investigated tissues after administration; the highest concentration of clevidipine was found in the heart whereas the lowest concentration was detected in the liver. In addition, clevidipine was almost undetectable in most tissues except for heart and brain at 90 min post‐dosing, suggesting that there was no apparent long‐term accumulation in rat tissues. For H152/81, the peak concentration of 3714 ± 319 ng/mL occurred at 0.129 ± 0.048 h, the half‐life was 10.08 ± 1.45 h and area under the concentration–time curve was 42091 ± 3812 ng h/mL after drug administration. In addition, H152/81 was found at significant concentration levels in all tissues, in descending order of lung, kidney, heart, liver, spleen and brain at each time point. The results of current study offer useful clues for better understanding the distribution and metabolism of clevidipine butyrate injectable emulsion in vivo.
CTO revascularization: Obstacles and options in balloon nonpenetrable lesions
Authors: Topaz On 
Published: July 2017

Key Points

CTO lesions resisting balloon crossing are located in moderate/severe tortuous coronary arteries contain more moderate/severe calcification burden and carry a higher J‐CTO score as compared with balloon crossable CTO lesions.
CTO lesions resisting balloon crossing do not constitute a homogenous group. In 25% of the patients, the resisting CTO was caused by stent restenosis and thrombus is an integral component of CTO in addition to calcium and fibrosis.
The excimer laser and rotational/orbital atherectomy are among useful debulking technologies capable of creating a “pilot recanalization channel” in the CTO that enables completion of the revasularization.
The importance of vision
Authors: Henry Timothy D. , Henry Christopher R. 
Published: July 2017

Key Points

Based on a systematic review and meta‐analysis of 8 studies, involving 2,559 subjects, both interventional cardiologists (3.21) and cardiac cath lab staff (2.76) had a significantly higher relative risk of posterior lens opacity than the control group.
It is essential to provide “best practice” in radiation dose management and lead shielding in the cath lab with the standard “As Low As Reasonably Achievable”!
There is a clear need for better data to quantitate the radiation risk and to design innovative strategies to decrease that risk.

AbstractObjectiveTo examine the relationship between occupational exposure to ionizing radiation and the prevalence of lens changes in interventional cardiologists (ICs) and catheterization laboratory (“cath‐lab”) staff.BackgroundExposure to ionizing radiation is associated with the development of lens opacities. ICs and cath‐lab staff can receive high doses of ionizing radiation without protection, and may thus be at risk for lens opacity formation.MethodsWe conducted a cross‐sectional study at an interventional cardiology conference. Study participants completed a questionnaire pertaining to occupational exposure to radiation and potential confounders for the development of cataracts, followed by slit‐lamp examination and grading of lens findings.ResultsA total of 117 attendees participated in the study, including 99 (85%; 49 ± 11 years‐old; 82% male) with occupational exposure to ionizing radiation and 18 (15%; 39 ± 12 years‐old; 61% male) unexposed controls. The prevalence of overall cortical and posterior subcapsular lens changes (including subclinical findings) was higher in exposed participants compared with controls (47 vs. 17%, P = 0.015). Occupational exposure and age over 60 were independent predictors of lens changes (odds ratio [95% CI]: 6.07 [1.38–43.45] and 7.72 [1.60–43.34], respectively). The prevalence of frank opacities was low and similar between the two groups (14 vs. 6%, P = 0.461). Most lens findings consisted of subclinical changes in the periphery of the lens without impact on visual acuity.ConclusionsCompared with unexposed controls, ICs and cath‐lab staff had a higher prevalence of lens changes that may be attributable to ionizing radiation exposure. While most of these changes were subclinical, they are important due to the potential to progress to clinical symptoms, highlighting the importance of minimizing staff radiation exposure.
