Background Administrative data are frequently used in stroke *** accurate identification of patients who had an ischaemic stroke,and those receiving thrombolysis and endovascular thrombectomy(EVT)is critical to ensure representativeness and *** examined differences in patient samples based on mode of identification,and propose a strategy for future patient and procedure identification in large administrative *** We used non-public administrative data from the state of California to identify all patients who had an ischaemic stroke discharged from an emergency department(ED)or inpatient hospitalisation from 2010 to 2017 based on International Classification of Disease(ICD-9)(2010-2015),ICD-10(2015-2017)and Medicare Severity-Diagnosis-related Group(MS-DRG)discharge *** identified patients with interhospital transfers,patients receiving thrombolytics and patients treated with EVT based on ICD,Current Procedural Terminology(CPT)and MS-DRG *** determined what proportion of these transfers and procedures would have been identified with ICD versus MS-DRG discharge *** Of 365099 ischaemic stroke encounters,most(87.70%)had both a stroke-related ICD-9 or ICD-10 code and stroke-related MS-DRG code;12.28% had only an ICD-9 or ICD-10 code and 0.02% had only an MS-DRG *** all transfers(99.99%)were identified using ICD *** identified 32433 thrombolytic-treated patients(8.9% of total)using ICD,CPT and MS-DRG codes;the combination of ICD and CPT codes identified nearly all(98%).We identified 7691 patients treated with EVT(2.1%of total)using ICD and MS-DRG codes;both MS-DRG and ICD-9/ICD-10 codes were necessary because ICD codes alone missed 13.2%of *** codes only pertain to outpatient/ED patients and are not useful for EVT *** ICD-9/ICD-10 diagnosis codes capture nearly all ischaemic stroke encounters and transfers,while the combination of ICD-9/ICD-10 and CPT codes are adequate

A traditional real option model is applied to a simulation of an oil production project. This analysis includes a carbon sequestration structure cost and possible revenues from carbon credit markets. The evaluation focuses on the determination of an optimal timing for the investment in different scenarios, regarding the volatility of the uncertain variable, oil prices. Historical prices data from different moments are used to estimate different prices uncertainty scenarios and its impacts on the decision making on building a carbon sequestration structure. The results are compared between a real option model to the ones obtained using the traditional net present value evaluation. Trigger point of investments are defined for different scenarios with and without carbon sequestration. There is also an analysis of the effects on decision-making in different scenarios for carbon market prices. It is perceived an important difference in the decision making considering the different methods of economic analysis. The real option model is a fundamental valuation tool in periods of high price volatility and higher sunk costs added to a project such as the carbon sequestration structure. Greenhouse gas projects demand high oil prices, positive market trend expectation and volatility.

The aim of this paper is to investigate the influence of physical and chemical factors on transport and use of substrate for Atta sexdens rubropilosa workers. Three types of rectangular fragments were used to study the physical influence factors： filter paper with paraffin, filter paper without paraffin and polyester film. To study the chemical factors, some fragments were impregnated with organic extract of orange albedo, others were soaked with soybean oil and for the remaining ones nothing was applied. The fonowing parameters were evaluated：（i） attractiveness of substrate for transport and number of loading workers per treatment; （ii） foraged material incorporation; （iii） rejection by numbers of fragments deposited in the garbage or beside the fungus garden. All the polyester film fragments carried out to the fungus garden were subsequently rejected. We verified that chemical factors of the substrate were more quickly detected by the workers, whereas physical factors were used as a criterion in the decision-making to reject or accept the substrate collected.

Solid polymer electrolytes based on chitosan and europium triflate were prepared by solvent casting and characterized by X-ray diffraction, scanning electron microscopy （SEM）, atomic force microscopy （AFM）, and photoluminescence spectroscopy. The X-ray diffraction exhibited that the samples were essentially amorphous with organized regions over the whole range of the salt content studied. The AFM analysis demonstrated that the smoother sample had roughness of 4.39 nm. Surface visualization through SEM revealed good homogeneity without any phase separation for more conductive samples and the less conductive showed some im- perfections on the surface. The emission and excitation spectra displayed the characteristic bands of Eu（CF3SO3）3 in addition to broad bands corresponding to the polymer host. The excited state 5D0 lifetime values ranged from 0.29-0.37 ms for the studied samples.

The experimental degradation of a water soluble dye, potassium indigo tetrasulfonate salt, has been studied using stand-alone ozonation and photocatalytic oxidation process. Progress of the dye oxidation was followed by UV-VIS spectrophotometric measurements at controlled operating conditions. The organic content of reaction samples was measured to verify the process efficiency in dye mineralization. According to current results, almost complete color removal was obtained for ozonation within about 1 h reaction time. The reduction of the organic load was almost 80% from its original while initial sulphur content decreased to 32.5%. Dye conversion of 100% was obtained by means of a photocatalytic process using TiO2 as catalyst at 294 nm irradiated UV light. This complete color removal for the catalytic process was observed within 7 min of reaction time. The calculated initial rate of reaction of photocatalysis treatment was 8 times faster than that of ozonolysis. However, the remaining organic load of photocatalysis was almost 88% from its original while the final sulphur content was 27.3%. This contrasting behavior of the performance of the type of oxidation process stressed importance of physicochemical phenomena and intermediates molecules present during dye degradation. An insightful and mechanistic aspect of the dye oxidation was developed by performing quantumchemical calculations.

The aim of this study was to determine the influence of collagen I and III on the expression of estrogen and progesterone receptors in equine endometrial fibrosis. A total of 25 crossbred mares were studies. Two endometrial samples were collected from each mare,1 inthe estrus and1 inthe diestrus phase. The samples were classified according to histological changes. Collagen was typed and quantified using the picrosirius red histochemical technique, and steroid receptors were identified by immunohistochemistry. The results showed a predominance of collagen type III in all the endometrial samples. The expression of estrogen (RE2) and progesterone (RP4) receptors varied according to the estrous cycle. RE2 and RP4 expression varied in the estrus and diestrus phases;there was no influence of collagen I or II on receptor expression.

Excessive mechanical loading is considered the major cause of rotator cuff tendinopathy. Although tendon problems are very common, they are not always easy to treat. Eccentric training has been proposed as an effective conservative treatment for the Achilles and patellar tendinopathies, but less evidence exists about its effectiveness for the rotator cuff tendinopathy. The mechanotransduction process associated with an adequate dose of mechanical load might explain the beneficial results of applying the eccentric training to the tendons. An adequate load increases healing and an inadequate(over or underuse) load can deteriorate the tendon structure. Different eccentric training protocols have been used in the few studies conducted for people with rotator cuff tendinopathy. Further, the effects of the eccentric training for rotator cuff tendinopathy were only evaluated on pain, function and strength. Future studies should assess the effects of the eccentric training also on shoulder kinematics and muscle activity. Individualization of the exercise prescription, comprehension and motivation of the patients, and the establishment of specific goals, practice and efforts should allbe considered when prescribing the eccentric training. In conclusion, eccentric training should be used aiming improvement of the tendon degeneration, but more evidence is necessary to establish the adequate doseresponse and to determine long-term follow-up effects.

This work presents and analyses a geostatistical methodology for spatial modelling of Soil Lime Requirements (SLR) considering punctual samples of Cation Exchange Capacity (CEC) and Base Saturation (BS) soil properties. Geostatistical Sequential Indicator Simulation is used to draw realizations from the joint uncertainty distributions of the CEC and the BS input variables. The joint distributions are accomplished applying the Principal Component Analyses (PCA) approach. The Monte Carlo method for handling error propagations is used to obtain realization values of the SLR model which are considered to compute and store statistics from the output uncertainty model. From these statistics, it is obtained predictions and uncertainty maps that represent the spatial variation of the output variable and the propagated uncertainty respectively. Therefore, the prediction map of the output model is qualified with uncertainty information that should be used on decision making activities related to the planning and management of environmental phenomena. The proposed methodology for SLR modelling presented in this article is illustrated using CEC and BS input sample sets obtained in a farm located in Ponta Grossa city, Paraná state, Brazil.
