Published: October 2018

The short-cycling operation of a heat pump decreases energy consumption efficiency. Short-cycling operations of GSHP (Ground Source Heat Pump System) occur when the ON / OFF control of a heat pump is used a partial load condition. It is considered effective that GSHP with capacity controls installs to suppress short-cycling operations. However, there is no report on any continuous operations by capacity control GSHP in actual operations.

We confirmed that GSHP (water to water) with capacity control operates short-cycling in the residence. Short-cycling operations were occurred a sudden load fluctuation due to opening or closing of the valves.

We conducted effective verification experiments of the thermal storage device at the artificial heat load fluctuations condition. When the thermal storage device installed upstream brine circulation line of the heat pump with the capacity control, continuous operations are performed. It was under the condition at the heating heat load of 5 kW is turned ON / OFF every 20 minutes. In this case, energy consumption efficiency of a heat pump is 13% higher than the efficiency without the thermal storage device.
Absorption Process in MgCl2-NH3 Thermochemical Batteries With Constant Mass Flow Rate
Authors: Hedayat Mofidi Seyyed Ali , Udell Kent S.
Published: October 2018

The working principle and performance of thermochemical batteries have been studied before [1–3]. In this paper, the performance of a thermochemical battery based on magnesium chloride and ammonia pair with a constant mass flow rate of ammonia gas is studied. It is shown that controlling the mass flow rate lowers the temperature of the reactive complex and increases the duration of the absorption process. However, it was observed that the reaction becomes mass transfer limited which slows the absorption rate and takes control of the reaction away from the mass flow controller. The progress of the reaction inside the reactor is studied in a single-cell reactor to understand the performance of these thermal batteries. It was shown that a reaction zone starts at the inlet and moves toward the end of the reactor. The mass transfer limited reaction zone movement reduces the absorption rate and temperature in the reaction zone.

Authors: Sunder Raj Komandur
Published: October 2018

For over two decades, there has been considerable interest in and research devoted to the use of artificial intelligence (AI) for maximizing the value of power generating assets.

AI may be thought of as application of intelligence in a systematic and rational manner to power plant equipment, components and processes for self-learning and solving complex problems. AI techniques are increasingly finding applications in the power industry in addressing issues related to performance, reliability, availability, maintenance, automation, cybersecurity, workforce, and others.

In the past several years, pace has accelerated in AI techniques, largely stemming from increased speed and power in computing, advances in technology, and utilization of algorithms. The Industrial Internet of Things (IIoT) is rapidly gaining ground by leveraging AI, digital assets and data analytics in managing and optimizing plant operations and performance of power generating assets.

This paper provides an overview of how AI techniques are being utilized to maximize the value of power generating assets and prognosis for future use of AI in the power industry.

Published: October 2018

Increasing the share of intermittent renewable energy sources in a power system poses challenges in terms of increased net load variability and maintaining grid stability and security. Operational flexibility of coal-fired power plants in China has played an essential and promising role in accommodating these nonequilibrium in the power grid. In the study, focusing on condensate throttling coupled with thermal storage tank measures, dynamic simulations of an entire 660 MW supercritical coal-fired power plant were developed via the GSE software. Then, the dynamic characteristics of main thermodynamic parameters and output power were described and compared, and operational flexibility performances of these measures were discussed. It turns out that: when condensate water flowrate decreases, the largest power ramp rate, power capacity, and energy capacity are 12.68 MW min−1, 12.76 MW, and 1084.70 MJ, respectively, and when condensate water flowrate increases, the largest power ramp rate, power capacity, and energy capacity are −5.49 MW min−1, −5.65 MW, and −695.94 MJ, respectively, which means condensate throttling without thermal storage tank measure is more suitable for power-up regulation than power-down regulation, but the shortest duration time is 130 s, which will restrict the operational flexibility regulation. However, coupling with thermal storage tanks, the deaerator water level can maintain a longer time. Meanwhile, at feedwater bypass 60% coupled with thermal storage tank, the largest power ramp rate, power capacity, and energy capacity are −3.62 MW min−1, −3.81 MW, and −897.31 MJ, respectively, and at condensate water bypass 60% coupled with thermal storage tank, the largest power ramp rate, power capacity, and energy capacity are 7.74 MW min−1, 7.88 MW, and 1829.38 MJ, respectively, and these parameter values are greater than condensate water flowrate directly increases or decreases 60%, which means condensate throttling coupling with thermal storage tanks can improve operational flexibility performances. The work is expected to reveal the performance parameters and strategies to provide detailed guidance of using turbine energy storage to improve operational flexibility of the coal-fired power plants.
Bluff-Body Flames in Hot and Diluted Environments
Authors: Liu Chengyu , Zhang Jian , Yang Tao , Ma Yanhong
Published: October 2018

Large eddy simulation/Flamelet progress variable approach is employed in current research to investigate how flame behaviour is influenced by bluff-body and coflow composition. We used Sydney bluff-body burner as the target burner. Computation grid in cylinder coordinates is approximately 2.7 million in total number, extended to the downstream location 80 times of jet diameter. Three coflow compositions with different oxygen ratio at the same inlet velocity are considered. Comparing to jet flames with hot and diluted coflow, instantaneous and statistical results showed that an introduction of bluff-body preheats the fuel and shortens the flame length. At lower oxygen ratio condition, a weaker reaction zone emerged, marked by lower temperature and OH concentration; the flame appeared lifted gradually, leading to a potential MILD combustion. Besides, bluff-body effect behaves differently in these flames: at lower oxygen ratio condition, a large-scale distribution of CH2O appeared as a marker of partial premixing and preignition reaction in recirculation area; on the contrary, in higher oxygen ratio case, the recirculation area brings out more reactive fuel at lower speed and higher temperature, hence ignitable in the vicinity of bluff-body.
Uncertainty Analysis of the Performance of Centrifugal Compressors: Numerical Model and Measured Uncertainties
Authors: Xu Lina , Huss Eric
Published: October 2018

Compressed air and gas are the lifeline of power plants. Deficient or unstable supply of air and gas can result in huge costs and revenue losses of plants. Thus, the accurate determination of performance of the compressors plays important role in prediction of the plant performance. In order to provide reliable and low cost operation for end users, an uncertainty analysis of volume flow, pressure ratio, and power consumption have been investigated and implemented to accurately determine the effect of the compressors to the plant performance. Mathematical models for the uncertainty treatments are proposed based on the ASME test code, and both the systematic errors originating from the measurement instruments and random errors rooted from the raw data are taken into consideration. Moreover, the approach of the uncertainty propagation is also presented through data reduction equations in this paper to evaluate the final performance. Both the rigorous numerical model and sophisticated data acquisition system instrumented in the test facility are employed to conduct the uncertainty analysis for a multi-stage centrifugal compressor. Comprehensive error sources such as ambient conditions, inter-stage pressures and temperatures, and rotational speeds are identified and studied for the final tolerance of the pressure ratio and power consumption of the whole compressor. The test uncertainty results of the compressor can help to improve the power plant field design and demonstrate quality assurance and quality control. Moreover, the tolerance analysis introduced in this paper can be extended to each component of the power plant system to optimize the performance of the whole power plant.
Heat Transfer Enhancement of Sensible Energy Storage for Low Temperature Application
Authors: Roy Sujit , Debnath Biplab Kumar
Published: October 2018

A shell and tube heat storage (1 MJ) has been designed computationally to enhance the heat transfer rate from heat transfer fluid (HTF) to the storage media. Concrete and water are considered as the sensible storage material and HTF, respectively. The system can be used to store the solar energy in the day time, which will be available in the absence of sunlight. Finite element based software, named COMSOL Multiphysics, is used for the study. The parameters analyzed, are tube outside diameter, radial distances between the tubes, number of tubes and inlet temperature of HTF. After a simulation time of 3000s, the increase of tube diameter from 1.03 to 1.71 cm is found to increase the average storage bed temperature by 6.3%. For the radial distances between the tubes to be 6 cm, the stored energy is maximum. The stored energies for 5 and 4 cm are 2.4 and 12.4% less than 6 cm, respectively, after duration of 6000s. The average bed temperature reaches to the steady state condition at 5147s with 19 tubes, whereas, with 25 tubes it takes 30.2% less time. Finally, the shell and tube heat storage has been optimized for higher heat transfer rate.
Computational Investigation of Full-Scale Tethered Underwater Kite
Authors: Ghasemi Amirmahdi , Olinger David J. , Tryggvason Gretar
Published: October 2018

In this paper, a numerical simulation of three-dimensional motion of tether undersea kites (TUSK) for power generation is studied. TUSK systems includes a rigid-winged kite, or glider, moving in an ocean current in which a tethered kite is connected by a flexible tether to a fixed structure. Kite hydrodynamic forces are transmitted through the tether to an electrical generator on the fixed structure. The numerical simulation models the flow field in a three-dimensional domain near the rigid undersea kite wing by solving the full Navier-Stokes equations. In order to resolve the boundary layer near the kite surface, adequate grid resolution is needed which increases the computational run time drastically especially in 3D simulations. Therefore, in this study a slip boundary condition is implemented at the kite interface to accurately predict the total drag, with lower grid resolution. In order to reduce the numerical run times, a moving computational domain method is also used. A PID controller is used to adjuste the kite pitch, roll and yaw angles during power (tether reel-out) and retraction (reel-in) phases. A baseline simulation study of a full-scale TUSK system is conducted in which the expected cross-current, figure-8 motions during a kite reel-out phase is captured. The effect of the tether drag on the kite motion and resulting power output is also investigated and compared with the results of the baseline simulation.
Multi-Component Separation and Purification of Natural Gas
Authors: Tamburello David , Hardy Bruce , Sulic Martin
Published: October 2018

Over the past decade, several technical developments (such as hydraulic fracturing) have led to an exponential increase in discovering new domestic natural gas reserves. Raw natural gas composition can vary substantially from source to source. Typically, methane accounts for 75% to 95% of the total gas, with the rest of the gas containing ethane, propane, butane, other higher hydrocarbons, and impurities, with the most common including H2O, CO2, N2, and H2S. All natural gas requires some treatment, if only to remove H2O; however, the composition of natural gas delivered to the commercial pipeline grids is tightly controlled. Sub-quality natural gas reserves, which are defined as fields containing more than 2% CO2, 4% N2, or 4 ppm H2S, make up nearly half of the world’s natural gas volume. The development of sub-quality, remote, and unconventional fields (i.e. landfill gas) can present new challenges to gas separation and purification methods. Adsorbent technologies, such as the use of activated carbons, zeolites, or metal-organic frameworks (MOFs), may hold the key to more efficient and economically viable separation methods.

This work proposes to prove the applicability of the multi-component potential theory of adsorption (MPTA) to a real world natural gas adsorbent system to properly characterize the adsorbent’s selectivity for an individual gas component using only the single component isotherms. Thus, the real-world gas separation/purification application of a specific adsorbent for a given gas stream can be obtained simply and effectively without the need for large experimental efforts or costly system modifications until after an initial computational screening of perspective materials has been completed. While the current research effort will use natural gas, which is the world’s largest industrial gas separations application, to validate the MPTA, the tools gained through this effort can be applied to other gas separation effort.
Assessment of Gas Turbine’s Cooling Systems Integrated With Bottoming Cycle
Authors: El-Damaty Waleed , Gadalla Mohamed
Published: October 2018

With the everlasting increase in the population, a huge surge in the electricity consumption can be noticed. Thus, the power and electricity generating power plants need to augment their performance to cope with this uprising problem. The main goal for most gas turbine power plants is to increase their efficiency and performance which can be achieved by increasing the turbine inlet temperature (TIT). However, increasing the TIT requires cooling of the turbine blades to extend its lifetime and avoid thermal stresses and oxidation rates. Usually, there are two routes to improve the turbine blade cooling, either scientist focus on the parameters that effect the cooling process such as the film cooling effectiveness, shape of holes and angle of injection, or the problem is approached from a thermodynamic point of view. It is well known that the air used to cool the turbine blades is bled from the compressor which causes a severe penalty on the thermodynamic efficiency and power output of the gas turbine. This paper main objective is to improve the gas turbine performance by lowering the temperature of the coolant lines bled from the compressor for turbine blade cooling resulting in a reduction in the amount of coolant mass flow rate required for turbine cooling which will reduce the penalty on the overall efficiency increasing it. For this purpose, three different configurations of Maisotsenko desiccant cooling systems were proposed to cool down coolant lines as well as the inlet air temperature. Optimization analysis was performed to determine the best operating parameters of the gas turbine as well as the cooling systems. Sensitivity analysis was conducted as well to investigate the effect of various variables on the gas turbine overall efficiency and the coolant mass flow rate. The results showed an increase in the overall efficiency from 42.57% to 43.83%, reduction in the amount of coolant mass flow rate that is bled from the compressor from 4.584 kg/s to 3.607 kg/s and in the cooling fraction from 4.72% to 3.9%.

Authors: Conte Eric , Fuks Benjamin
Published: October 2018

We provide a comprehensive and pedagogical introduction to the MADANALYSIS 5 framework, with a particular focus on its usage for reinterpretation studies. To this end, we first review the main features of the normal mode of the program and how a detector simulation can be handled. We then detail, step-by-step, how to implement and validate an existing LHC analysis in the MADANALYSIS 5 framework and how to use this reimplementation, possibly together with other recast codes available from the MADANALYSIS 5 Public Analysis Database, for reinterpreting ATLAS and CMS searches in the context of a new model. Each of these points is illustrated by concrete examples. Moreover, complete reference cards for the normal and expert modes of MADANALYSIS 5 are provided in two technical appendices.
A simple expression for heavy to light meson semileptonic decays form factors
Authors: Pham T. N.
Published: October 2018

Like the two-photon and two-gluon decays of the [Formula: see text]-wave [Formula: see text] and [Formula: see text] charmonium state for which the Born term produces a very simple decays amplitude in terms of an effective Lagrangian with two-quark local operator, the Born term for the processes [Formula: see text] and [Formula: see text], could also produce the [Formula: see text] and [Formula: see text] meson semileptonic decays with the light meson [Formula: see text], [Formula: see text] in the final state. In this approach to heavy-light meson form factors with the [Formula: see text], [Formula: see text] meson treated as Goldstone boson, a simple expression is found for the decays form factors, given as: [Formula: see text], with [Formula: see text], [Formula: see text] for [Formula: see text], [Formula: see text] form factors, and [Formula: see text] for [Formula: see text], [Formula: see text] form factor. The purpose of this paper is to show that this expression for the form factors could describe rather well the [Formula: see text]-behavior observed in the BaBar, Belle and BESIII measurements and lattice simulation. In particular, the [Formula: see text] form factors are in good agreement with the measured values in the whole range of [Formula: see text] showing evidence for [Formula: see text] breaking with the presence of [Formula: see text] term in the quark propagator, but some corrections to the Born term are needed at large [Formula: see text] for [Formula: see text], [Formula: see text] form factors.
The cicadas (Hemiptera: Cicadidae) of Panama including the description of six new species, three new combinations, one new synonymy, and nine new records
Authors: SANBORN ALLEN F.
Published: October 2018

The known cicada fauna of Panama is identified. Procollina quadrimaculata n. sp., P. stigmosa n. sp., Guyalna woldai n. sp., Herrera nigratorquata n. sp., H. sigillata n. sp. and Conibosa megalopercula n. sp. are described as new. Proarna germari Distant, 1905 n. syn. is shown to be a junior synonym of Proarna invaria (Walker, 1850). Pacarina championi (Distant, 1881) is returned to Proarna Stål, 1864 to become Proarna championi Distant, 1881 n. comb. again. The first records of Proarna invaria (Walker, 1850), Guyalna bogotana (Distant, 1892), Dorisiana cachla (Distant, 1899), Ollanta modesta (Distant, 1881), Pacarina schumanni Distant, 1905, Majeorona truncata Goding, 1925, Herrera lugubrina lugubrina (Stål, 1864), Calyria cuna (Walker, 1850), and Calyria telifera (Walker, 1858) are provided. The records for Ollanta modesta (Distant, 1881) are the first records of the genus Ollanta Distant, 1905 for Panama. The records for Calyria cuna (Walker, 1850), and Calyria telifera (Walker, 1858) are the first record of the genus Calyria Stål, 1862 and the Tribe Parnisini Distant, 1905 in Panama. Previous records of Dorisiana metcalfi Sanborn & Heath, 2014 (= Cicada viridis Olivier, 1790), Carineta fasciculata (Germar, 1830), and Selymbria stigmatica (Germar, 1834) are considered to be misidentifications of G. bogotana, C. maculosa (Torres, 1948), and S. pluvialis (Ramos & Wolda 1985) respectively so that D. metcalfi, C. fasciculata, and S. stigmatica are removed from the cicada fauna of Panama. The Panamanian record of Dorisiana semilata (Walker, 1850) is shown to be a mistake and the species is removed from the faunal list as well. The currently known Panamanian cicada fauna is comprised of 54 described species along with six species from the literature that remain undetermined from 22 genera, seven tribes and three subfamilies. Bergalna xanthospila (Germar, 1830) is reassigned to Dorisiana Metcalf, 1952 to become Dorisiana xanthospila (Germar, 1830) n. comb. Fidicinoides flavibasalis (Distant, 1905) is reassigned to Guyalna Boulard & Martinelli, 1996 to become Guyalna flavibasalis (Distant, 1905) n. comb.

Published: October 2018

Examination of normal pore canals, especially sieve-type pore canals, in living and fossil representatives of ten genera of the family Limnocytheridae, subfamily Timiriaseviinae, has revealed important diversity of structure. These complex pore canals have been studied via high-resolution scanning electron microscopy (the Cartographic Method) and analysed via the application of newly devised indices to assess patterns of consistency and variation in both detailed structure of individual pores and of their distribution on the calcified valve. The timiriaseviine taxa are compared with species of the genera Limnocythere, sub-family Limnocytherinae and Cyprideis (family Cytherideidae). The relationship between the living animal and its aquatic environment is discussed in the light of previous studies and of new evidence herein. The importance of normal pore canals for systematics is highlighted by the recognition and definition of the new tribe Gomphodellini Danielopol, Cabral & Lord nov. tribe, subfamily Timiriaseviinae, family Limnocytheridae.

Published: October 2018

Wharton’s jelly-derived mesenchymal stromal cells (WJ-MSCs) have distinct immunomodulatory and protective effects against kidney, liver, or heart injury. Limited studies have shown that WJ-MSCs attenuates oxygen–glucose deprivation-mediated inflammation in hippocampal slices. The neuroprotective effect of intracerebral WJ-MSC transplantation against stroke has not been well characterized. The purpose of this study was to examine the neuroprotective effect of human WJ-MSC (hWJ-MSC) transplants in an animal model of stroke. Adult male Sprague–Dawley rats were anesthetized and placed in a stereotaxic frame. hWJ-MSCs, pre-labeled with chloromethyl benzamide 1,1’-dioctadecyl-3,3,3’3’- tetramethylindocarbocyanine perchlorate (CM-Dil), were transplanted to the right cerebral cortex at 10 min before a transient (60 min) right middle cerebral artery occlusion (MCAo). Transplantation of hWJ-MSCs significantly reduced neurological deficits at 3 and 5 days after MCAo. hWJ-MSC transplants also significantly reduced brain infarction and microglia activation in the penumbra. Grafted cells carrying CM-Dil fluorescence were identified at the grafted site in the ischemic core; these cells were mostly incorporated into ionized calcium-binding adaptor molecule (+) cells, suggesting these xenograft cells were immuno-rejected by the host. In another set of animals, hWJ-MSCs were transplanted in cyclosporine (CsA)-treated rats. hWJ-MSC transplants significantly reduced brain infarction, improved neurological function, and reduced neuroinflammation. Less phagocytosis of CM-dil-labeled grafted cells was found in the host brain after CsA treatment. Transplantation of hWJ-MSC significantly increased glia cell line-derived neurotrophic factor expression in the host brain. Taken together, our data support that intracerebral transplantation of hWJ-MSCs reduced neurodegeneration and inflammation in the stroke brain. The protective effect did not depend on the survival of grafted cells but may be indirectly mediated through the production of protective trophic factors from the transplants.
The value of ultrasound in diagnosis of pneumoperitoneum in emergent or critical conditions: A meta-analysis
Authors: Jiang Libing , Wu Jing , Feng Xia
Published: October 2018

Background:

Hollow organs perforation is a life-threatening condition. Early diagnosis and emergent intervention are important. Bedside ultrasound may be an alternative diagnostic tool for this condition.

Objective:

The aim of this study was to explore the diagnostic value of ultrasound of pneumoperitoneum in emergent or critical conditions through meta-analysis.

Methods:

PubMed, EMBASE, and Cochrane Library were systematically searched for potential studies. Then, two reviewers performed the processes of study selection, data extraction, and quality assessment independently. Finally, diagnostic indexes were analyzed with STATA 12.0 software (Serial No. 40120519635).

Results:

A total of five studies with moderate to high quality were eligible for meta-analysis. The pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio and their 95% confidence interval were 0.91 (95% confidence interval = 0.86–0.94), 0.96 (95% confidence interval = 0.75–0.99), 22.05 (95% confidence interval = 3.10–156.96), and 0.10 (95% confidence interval = 0.07–0.15), respectively. The area under the summary receiver operating characteristic curve was 0.92 (95% confidence interval = 0.90–0.94).

Conclusion:

Abdominal ultrasound is a useful alternative tool in diagnosing of pneumoperitoneum. However, due to limited evidence, it is not yet indicated for routine clinical use.
Return to Play After Thigh Muscle Injury: Utility of Serial Ultrasound in Guiding Clinical Progression

Published: October 2018

Return to play after thigh muscle strain injury is difficult to predict and recurrent injury rates are high. There is currently no agreement on the optimal return to play protocol following muscle injury and utility of imaging is debated. Ultrasound has become an increasingly utilized imaging modality and offers several potential advantages for monitoring the return to play process following muscle injury. An ultrasound scanning protocol is presented which provides real-time guidance on muscle healing and may assist with identification of those athletes at risk of reinjury who otherwise appear clinically fit for return to play.

Estudos evidenciam que a realização africada de oclusivas alveolares antecedidas por glide palatal é sensível à avaliação social, configurando-se um estereótipo de estigma social. Objetivamos averiguar os efeitos de polidez de uma variante do tipo estereótipo, em contextos de preservação de faces, em uma comunidade de práticas escolares de Aracaju/SE. Para a constituição do corpus, realizamos 32 gravações de interação conduzida em rede social, e 20 gravações de entrevistas sociolinguísticas. A distância social atuou significativamente, pois quanto mais distante os interlocutores, mais procuraram automonitorar-se, o que se reflete no uso da variante africada. O resultado reforça que a variante é um estereótipo de estigma social na comunidade.
O CASO DE –A-MO(S) VERSUS –E-MO(S) e –E-MO(S) VERSUS –I-MO(S): VARIAÇÃO MORFÊMICA OU ESPECIALIZAÇÃO TEMPORAL?
Authors: Pereira Ivelã
Published: October 2018

Sobre o fenômeno linguístico da concordância verbal de primeira pessoa do plural (1PP) em verbos regulares de 1ª e 2ª conjugação (CI e CII), em contextos de presente e pretérito perfeito do Indicativo (IdPr e IdPt2), observamos que existem formas de realização não-canônicas (AMARAL, 1920; CASTILHO, 1992, 2016; CÂMARA JUNIOR, 1970). Nesse contexto, falemo(s) e comimo(s) são exemplos de formas não-canônicas (NC) que variariam com as canônicas (falamos e comemos). No entanto, conforme dados de Pereira, Lehmkuhl-Coelho e Loregian-Penkal (2016) e Foeger, Yaconvenco e Scherre (2017), parece que essas formas NC costumam estar bastante associadas a contextos de Pretérito Perfeito do Indicativo, o que indicaria uma especialização para um contexto temporal específico. Desse modo, se cada uma das formas se especializar para um contexto (falamos para IdPr, e falemos para IdPt2), é possível ainda tratá-las como variantes? Essa especialização de fato está acontecendo ou tem havido variação entre as formas canônicas e não-canônicas? A partir disso, pode-se dizer que se trate de um fenômeno morfêmico ou morfológico? Com base nessas indagações, propomo-nos a fazer uma discussão teórica sobre variação em relação a tal fenômeno linguístico. Para tanto, nosso suporte teórico ancora-se em: Weinreich, Labov e Herzog (2006 [1975], 1968), Labov (2008 [1972], 1978, 1984, 1994, 2001), Weiner e Labov (1983), Lavandera (1978), Guy (2000, 2001), Tagliamonte (2006), Camacho (2010), entre outros.
AQUISIÇÃO DE ORAÇÕES RELATIVAS NO PB EM CONTEXTO DE INPUT VARIÁVEL
Authors: Abreu Gomes Christina , Baptista de Abreu Ana Cristina
Published: October 2018

Este trabalho focaliza a aquisição de orações relativas por crianças adquirindo o Português Brasileiro em contexto de input variável, considerando os pressupostos da Sociolinguística Variacionista e dos Modelos Baseados no Uso. As relativas infantis iniciais apresentam estruturas mais simples até que as crianças produzam relativas alvo observadas na fala dos adultos, além disso, o processo desenvolvimental é influenciado pela frequência de ocorrência na fala dessas orações e pelo grau de similaridade estrutural com padrões mais recorrentes da língua.  Isto é, as relativas mais frequentes e com a estrutura mais comum na língua são adquiridas primeiro pelas crianças (DIESSEL & TOMASELLO, 2000, 2005; XXXX, data). Considerando que o PB se caracteriza por um processo de mudança das orações relativas (TARALLO, 1986, 1993), nossa hipótese é que a aquisição de relativas também vai refletir a dinamicidade da mudança. A análise de dados de produção espontânea de 23 crianças moradoras da cidade do Rio de Janeiro, componentes da Amostra AQUIVAR/PEUL/UFRJ, mostrou que as relativas infantis refletem a mesma direcionalidade de mudança atestada na fala dos adultos da mesma comunidade de fala, embora contenham características inerentes à fase aquisitiva, (MOLLICA, 2003; XXXX, data). Portanto, estes resultados evidenciam que a aquisição depende não só da frequência das estruturas no input, mas também da similaridade que determinadas estruturas apresentam com outras sentenças da língua, e que as crianças participam da implementação da mudança linguística pelo processo de incrementação (LABOV, 2007, 2010).
LEXEMAS E CONSTRUÇÃO: ATRAÇÃO, COERÇÃO E VARIAÇÃO

Sob orientação funcional-construcionista ou socioconstrucionista, desenvolvemos nossa reflexão sobre a temática da correlação entre lexemas e construção em prol de discutir objetos observacionais e questões teórico-metodológicas referentes aos fenômenos da atração e da variação implicados nessa compatibilização. Além do exame de preferências e restrições associadas a slots de construções, interessa-nos a análise da relação de similaridade entre as possibilidades de preenchimento, bem como a frequência/produtividade de compatibilização de um lexema em um slot de uma dada construção em relação aos lexemas que se associam a um outro slot diferente da mesma construção. Em outras palavras, importa salientar a necessidade da observação de que palavras são fortemente atraídas ou repelidas por slots em uma construção (ou seja, ocorrem com mais frequência ou com menos frequência do que o esperado) e do grau de similaridade funcional entre elas.

A screening tool was implemented pre procedure to predict the level of care patients would require post procedure.

Findings:

The system correctly identified 94% of patients able to go to the coronary care unit (CCU) rather than requiring a cardiac intenstive care unit (CICU) bed.

Conclusion:

Levels of care required vary between patients undergoing TAVI; in the majority of cases, this can be predicted in advance by the procedure type, level of sedation and individual comorbidities of the patient. Further research into the post-care needs of patients over 90 years of age is needed.

Authors: A. Faden Asma’a
Published: October 2018

The aqueous and methanolic extracts of Areca catechu seeds (known as areca nut: a component of a betel quid, where their chewing habitis a popular cultural tradition in some South East Asian countries used as an oral cleanser) have shown some antimicrobial potentials against some oral bacteria which are capable of causing opportunistic infections in the mouth. The objective of this study is to detect the antibacterial activities of aqueous and methanolic extracts of Areca catechu against Escherichia coli and Staphylococcus aureus.Manystudies showed different antibacterial activity, depending on the Areca catechu extracts method, concentration, and the bacterium under test. The aqueous and methanolic extracts were added to growth medium of Escherichia coli or Staphylococcus aureus. The antibacterial activities of the attained fractions were assessed using agar-well diffusion test. In this study we have observed that the Methanolic extract inhibited the growth of Escherichia coli or Staphylococcus aureus, while aqueous extract was ineffective. In conclusion the methanolic extract of the Areca catechu seeds “areca nut” can be a potential source for developing antibacterial agent against E. coli and S. aureus which are commonly found on human oral cavity and responsible for some oral infections.

Published: October 2018

Subsistence hunting is a key activity for indigenous Amazonian people. Traditional Tsimane’ bow hunting was strongly affected by the introduction of firearms over 30 years ago. Tsimane’ of Bolivia maintain traditional hunting techniques with bows and arrows, sometimes in conjunction with modern firearms. This study explores Tsimane' perceived costs and benefits of bow- versus gun-hunting. We consider cultural conservation in addition to factors typical in ecological comparisons of traditional and introduced hunting technologies. Firearms are expensive and less reliable than bows and arrows. Costs of purchasing firearms requires market engagement and surplus production to generate cash. Tsimane’ do not identify overhunting as one of the costs of firearms; though multiple studies show reduced game populations in areas under moderate to intense gun-hunting pressure. In sum, Tsimane’ identify multiple benefits to traditional hunting technology, while firearms have a strong effect of the loss of knowledge regarding fabrication of bows and arrows, and present a challenge to Tsimane’ cultural identity as bow-hunters.

AbstractThe global resurgence of religion seems nowadays to generate repression as it tends to create international instability, political upheaval and chaotic states. Most political scientist and intelligence experts did not predict the resurgence because it was not supposed to happen in a country participating so thoroughly in modernization and Westernization.  It is interesting to learn that so many scholars and policymakers who monitored the international politics have missed the warning signs about the resurgence. It because of the argument that religion was the object that needed to vanish for modern international politics to come into being. Religion has been, and largely remains, what the discipline of International Relations (IR) can speak about only as a threat to its own existence.  This paper tries to explain how the resurgence of religion has been on the spotlight in the eyes of IR Study. It also explains that the IR Study now faces a serious dilemma to treat religion in such a proper way. Various arguments on the strategy to deal with religion has come up that makes religion a more and more interesting subject in academic realms.Kata Kunci: Kebangkitan agama, modernisasi, pencerahan, sekularisasi, Westphalia

Authors: Twardowski Andrzej
Published: October 2018

This article provides an overview of two approaches to peer-mediated intervention that have been effective in improving the social and communicative interactions among preschool children with developmental disabilities and their classmates without disabilities. These peer-mediated interventions involve teaching facilitative initiation and responsive interaction strategies to peers and teaching sociodramatic scripts. The studies presented in this paper prove that thanks to relationships with properly trained peers disabled children more often get involved in team games, more often establish interactions with their peers, are more eager to talk to them and less often exhibit socially unacceptable behaviors.

Authors: Polit Andres Fernando , Polit Fernando Eduardo , Polit Joaquin
Published: October 2018

Purpose: To describe a case of inferior bullous keratopathy caused by iris fibers resolved with laser diode 532.Case report: A 74-year-old woman consulted for deterioration of visual acuity in right eye, accompanied by foreign body sensation. A phacoemulsification surgery with IOL implant had been performed in both eyes three months before. Best corrected visual acuity reached 20/40 in right eye. Slit lamp examination revealed bullous keratopathy located in the central inferior quarter of the cornea of her right eye. Gonosioscopy was performed to rule out having nucleus fragments in the inferior angle. With higher magnification, a pair of fine undulating fibers were observed coming from the anterior layers of the iris and making contact with the posterior face of the cornea. Photocoagulation of the iris fibers was performed with laser diode 532 and photodisruption with Nd-YAG laser, applied at the base of the fibers. After nine days, resolution of corneal edema, and disappearance of bullae was observed.  Best corrected visual acuity improved to of 20/25.Conclusions: photocoagulation of iris fibers with laser diode 532 complemented with photodisruption with Nd-YAG laser, in patients with iridoschisis, is an alternative to avoid endothelial decompensation and corneal edema, which may require a corneal transplantation.
