The present article examines how Dr.Zakir Naik, the celebrated Islamic preacher, uses language to persuade the audience in his popular speeches. The paper tests the persuasive approaches proposed in Connor and Lauer’s model by segmenting a representative sample of Dr. Zakir Naik’s You Tube video scripts into discourse units based on the three fundamental resources of persuasive appeals: Rationality, Credibility, and Affection.For the implementation of appeals, the types of convincing approaches were identified and analysed. Using manual transcription and NVivo 12 for codification and analysis, the findings reveal that logical strategies have been used predominantly in Zakir Naik’s speeches. Amongst the Rational appeals, using authoritative sources has been mostly utilized. The results highlight that varied persuasion tactics show their functions in constructing the convincing power of his arguments.

MAC design in a vehicle network is a challenging task due to high node speed, frequent topology changes, lack of infrastructure, and different QoS requirements. Several medium access control protocols based on Time Division Multiple Access (TDMA) have recently been suggested for VANETs in an effort to guarantee that all cars have sufficient time to send safety messages without collisions and to decrease the end-to-end delay and the loss ratio of packets. The reasons for using the collision-free media access control paradigm in VANETs are identified in this document. We then present a new topology-based classification and provide an overview of the MAC protocols suggested for VANETs based on TDMA. We concentrate on these protocols ' features as well as their advantages and constraints. Finally, we provide a qualitative comparison and address some open problems that need to be addressed in future studies to enhance the efficiency of TDMA-based MAC protocols for vehicle-to-vehicle (V2V) and vehicle to infrastructural (V2I) communications.

Anxiety is a continuous fear of something bad that may happen. It is one of the common problems. Modernization and urbanization along with the nuclearisation of the family system has lead to an increase the anxiety among everybody especially the youth. The emerging youth are the future of the nation and play a vital role in its development. This is the stage which is neither childhood nor adulthood, is apprehensive of the future and has tendency to develop many fears of the unknown. In India there are very less number of psychotherapists available and lot of people with psychological problems like anxiety do not have access to such services. There is a need of short therapy which can help people solve their problems in short time. This paper attempts to summarize the results of research conducted to see the effect of a short therapy like SFBT on anxiety among the emerging youth. The study was designed with an experimental and control group. 5 participants with mild to moderate anxiety received the solution focused therapy and 5 participants with mild to moderate anxiety were re-administered the anxiety inventory after a gap of about one month. The measuring tool for anxiety used for the study was Beck’s Anxiety Inventory. The statistical analysis included t-test of independent sample and repeated measure ANOVA.

Glaucoma is a malady of the optic nerve brought about by the expansion in the intraocular weight of the eye. It for the most part influences the optic plate by expanding the cup size. In this proposed method the clinical parameter such as vertical optic cup to disk ratio (CDR) is determined to identify the glaucomatous disease. The segmentation of optic disc (OD) and optic cup in retinal fundus image is an important step in the determination of CDR. Optic Disc is extracted from the fundus image by circular region of interest with Hough transformation. Linear regression fit is used to find the Gold standard value for the experimentally obtained CDR A Bayesian classifier is used to train the classifier set of CDR values obtained. Results produced from the classification obtain a accuracy of 94.28%, sensitivity of 94.38% and specificity of 94.11%. ROC curve is plotted to study the relation between specificity and sensitivity of the CDR and GSV. This proposed approach is robust in segmentation and the region boundaries are precise and is able to yield regions more homogeneous which can be used for objective mass screening of retinal images for early detection of Glaucoma.

Objectives: This study quantified the burden of hypoxic respiratory failure (HRF)/persistent pulmonary hypertension of newborn (PPHN) in preterm and term/near-term infants (T/NTs) by examining health care resource utilization (HRU) and charges in the United States.

Methods: Preterms and T/NTs (≤34 and >34 weeks of gestation, respectively) having HRF/PPHN, with/without meconium aspiration in inpatient setting from January 1, 2011-October 31, 2015 were identified from the Vizient database (first hospitalization=index hospitalization). Comorbidities, treatments, HRU, and charges during index hospitalization were evaluated among preterms and T/NTs with HRF/PPHN. Logistic regression was performed to evaluate mortality-related factors.

Results: This retrospective study included 504 preterms and 414 T/NTs with HRF/PPHN. Preterms were more likely to have respiratory distress syndrome, neonatal jaundice, and anemia of prematurity than T/NTs. Preterms had significantly longer inpatient stays (54.1 vs 29.0 days), time in a neonatal intensive care unit (34.1 vs 17.5 days), time on ventilation (4.7 vs 2.2 days), and higher total hospitalization charges ($613,350 vs $422,558) (all P<0.001). Similar rates were observed for use of antibiotics (96.2% vs 95.4%), sildenafil (9.5% vs 8.2%), or inhaled nitric oxide (93.8% vs 94.2%). Preterms had a significantly higher likelihood of mortality than T/NTs (odds ratio: 3.6, 95% confidence interval: 2.3-5.0).

Conclusions: The findings of more severe comorbidities, higher HRU, hospitalization charges, and mortality in preterms than in T/NTs underscore the significant clinical and economic burden of HRF/PPHN among infants. The results show significant unmet medical need; further research is warranted to determine new treatments and real-world evidence for improved patient outcomes.

Authors: AH El-Gilany
Published: September 2019

Self-controlled case series study (SCCSS) is a novel strategy to control between-person confounders by comparing the risk and reference periods in each patient. SCCSS investigates the association between transient exposure and an adverse event. It was developed to study adverse reactions to vaccines. Risk periods are defined during or after the exposure. Then the method finds a relative incidence i.e. the incidence in risk periods relative to the incidence in control periods. This editorial describes the definition, origins, design, assumptions, advantages, and limitations of this research method.
The influence of porosity on nanoparticle formation in hierarchical aluminophosphates
Authors: Potter Matthew E , Riley Lauren N , Oakley Alice E , Mhembere Panashe M , Callison June , Raja Robert
Published: September 2019

In this work we explore the deposition of gold onto a silicoaluminophosphate, using a variety of known nanoparticle deposition techniques. By comparing the gold particles deposited on a traditional microporous aluminophosphate, with an analogous hierarchical species, containing both micropores and mesopores, we explore the influence of this dual porosity on nanoparticle deposition. We show that the presence of mesopores has limited influence on the nanoparticle properties, but allows the system to maintain porosity after nanoparticle deposition. This will aid diffusion of reagents through the system, allowing continued access to the active sites in hierarchical systems, which offers significant potential in catalytic oxidation/reduction reactions.

SN2010da/NGC 300 ULX-1 was first detected as a supernova impostor in 2010 May and was recently discovered to be a pulsating ultraluminous X-ray source. In this Letter, we present Very Large Telescope/X-shooter spectra of this source obtained in 2018 October, covering the wavelength range 350–2300 nm. The J- and H-bands clearly show the presence of a red supergiant (RSG) donor star that is best matched by a MARCS stellar atmosphere with T
eff = 3650–3900 K and log(L
bol/L
⊙) = 4.25 ± 0.10, which yields a stellar radius R = 310 ± 70R
⊙. To fit the full spectrum, two additional components are required: a blue excess that can be fitted either by a hot blackbody (T ≳ 20,000 K) or a power law (spectral index α ≈ 4) and is likely due to X-ray emission reprocessed in the outer accretion disk or the donor star; and a red excess that is well fitted by a blackbody with a temperature of ∼1100 K, and is likely due to warm dust in the vicinity of SN2010da. The presence of an RSG in this system implies an orbital period of at least 0.8–2.1 yr, assuming Roche-lobe overflow. Given the large donor-to-compact object mass ratio, orbital modulations of the radial velocity of the RSG are likely undetectable. However, the radial velocity amplitude of the neutron star is large enough (up to 40–60 km s−1) to potentially be measured in the future, unless the system is viewed at a very unfavorable inclination.

Authors: Chen Wan-Hao , Liu Chang , Han Yan-Feng , Liang Jian-Dong , Tian Wei-Yi , Liang Zong-Qi
Published: September 2019

In this paper, we introduce three new species ofSimplicillium, viz.S. cicadellidae,S. formicidaeandS. lepidopterorum, which were isolated from an infected leafhopper, ant and carpenterworm, respectively. Morphological comparisons and phylogenetic analyses based on multigene datasets (LSU+RPB1+RPB2+TEF and ITS+LSU) support the establishment of the three new species.Simplicillium cicadellidaewas distinguished from other species in morphological characteristics by having smaller phialides and ellipsoidal conidia, and lacking octahedral crystals. The reverse of colonies were yellowish (#FFBF00), especially in the middle, and radially sulcate.Simplicillium formicidaewas morphologically distinguished from other by having longer phialides and filiform to fusoid conidia, and by lacking octahedral crystals.Simplicillium lepidopterorumwas morphologically distinguished from other species by having smaller, ellipsoidal to fusiform conidia, and by lacking octahedral crystals. The reverse of the colony was pale white. The three new species are likely to be nourished by plant to animal (especially insect) nutrients based on the evolutionary pattern of the Hypocreales, and they are described herein as being clearly distinct from other species inSimplicillium.
Outcomes of the “steady-state crisis” experiment in the MIR reactor channel

Published: September 2019

To license nuclear fuel for nuclear power plants, data on the behavior of fuel elements (FE) under design-basis accidents are required. These data are obtained during tests of fuel assemblies (FA) and single fuel elements in research reactor channels followed by post-test studies in protective chambers.

A reactivity-initiated accident (RIA) with an unauthorized release of CPS rods from the reactor core leads to a pulsed channel power increase. This accident can proceed according to two scenarios: without a critical heat flux (CHF) on the fuel element jacket at the final stage and with a dry heat flux. To date, a series of experiments have been carried out according to the first scenario in the MIR reactor channel and the corresponding data on the behavior of fuel elements have been obtained. An urgent task for today is to prepare and conduct reactor experiments according to the second scenario.

The main experimental parameter that determines the behavior and final state of the studied fuel elements is their temperature. No experimental data were found on the critical heat flux for the rod bundles in the low coolant mass flow rate region (experiments in the MIR reactor channel can be conducted in the range of 200–250 kg/(m2s)). The available data are in the extrapolation range.

The “steady-state crisis” experiment was conducted to obtain data on the critical heat flux value within the specified coolant mass flow rate range in the MIR reactor channel. The test object was a jacket fuel assembly composed of three shortened VVER-1000 fuel rods with a length of 1230 mm (the fuel part length = 1000 mm) installed in a triangular grid at a pitch of 12.75 mm, which is a cell of the VVER-1000 core. This assembly configuration is used for in-pile tests to study the behavior of fuel elements under emergency conditions.

The in-pile testing results are presented. The paper shows the possibility of detecting the start and development of a dry heat flux based on the readings of thermocouples located inside the FE kernel. As a result, the directly measured test parameters were used to determine the critical heat flux value.

Water-cooled water-moderated reactors (VVER) are widely used at Russian nuclear power plants. The VVER reactor core is formed by fuel assemblies consisting of fuel rods. The fuel in fuel rods is uranium dioxide. The safety of the reactor operation is ensured through stringent requirements for the maximum nuclear fuel temperature. Calculation of temperature fields within the reactor core requires associated problems to be solved to determine the internal energy release in fuel based on neutronic characteristics. Dedicated software for such calculations is not available to a broad range of users. At the present time, there are numerical thermophysical modeling packages available for training or noncommercial applications which are used extensively, including Elcut, Flow Vision, Ansys Fluent, and Comsol Multiphysics. Verification of the obtained results is becoming an important issue in building models using these calculation packages.

An analytical solution was obtained as part of the study for the fuel temperature field determination. A program was developed in MathCAD based on this solution. A model was developed in Comsol Multiphysics to determine the fuel temperature field with constant thermophysical properties in a two-dimensional problem statement. The numerical model was verified using the analytical solution. The influence of the number of the grid nodes on the solution accuracy was established. The analytical solution can be used to determine the fuel temperature field at any radial coordinate of the reactor. The temperature field determination model developed in MathCAD can be used to verify numerical models of the fuel temperature field determination developed in dedicated packages.

Published: September 2019

Purpose

To evaluate and compare optical and visual quality of eyes implanted with spherical and aspheric intraocular lenses (IOLs).

Methods

Twenty eyes of 17 patients were implanted with the AcrySof Natural IQ aspheric IOL (SN60WF) and 20 eyes of 15 patients were implanted with the AcrySof Natural spherical IOL (SN60AT). Photopic monocular distance best spectacle-corrected visual acuity (BSCVA) was recorded at 6 months postoperatively. Corneal aberrations were measured with the CSO Eyetop topographer, and ocular aberrations were measured with a Hartmann-Shack aberrometer for a 6-mm pupil. Ocular spherical aberration was computed for different pupil diameters (3, 4, 5, and 6 mm).

Results

No statistically significant differences were found between the BSCVA of the AcrySof IQ IOL (0.023±0.004 logMAR) and AcrySof Natural IOL (0.031±0.003 logMAR) (
P
=.15). The corneal higher order aberrations showed no statistically significant differences between groups (
P
>.1). However, spherical aberration and higher order ocular aberrations in the AcrySof IQ eyes were lower than eyes implanted with the AcrySof Natural IOL (
P
<.01). A statistically significant increase in the spherical aberration coefficient with pupil diameter was found only for the spherical IOL group (
P
=.0023). Statistically significant differences in the spherical aberration coefficient were found between groups at all pupil diameters (
P
<.001).

Conclusions

A significant reduction in ocular spherical aberration was noted after AcrySof IQ IOL implantation at all pupil diameters compared to the spherical IOL, although photopic BSCVA between groups remained similar. [

Effect of different PVA and steel fiber length and content on mechanical properties of CaCO3 whisker reinforced cementitious composites
Authors: Cao M. , Xie C. , Li L. , Khan M.
Published: September 2019

In this paper, calcium carbonate (CaCO3) whisker as a fiber reinforcement is mixed with steel and PVA fiber to form a multiscale hybrid fiber reinforced cementitious composites (MHFRCC). ASTM standard and post-crack strength techniques are performed to evaluate the mechanical properties of MHFRCC. The 1.25 % long steel fiber, 0.55 % short PVA fiber and 2.0 % CaCO3 whisker specimens showed the best flexural behavior before L/600 deflection. However, 1.5 % long steel fiber, 0.4 % long PVA fiber and 1.0 % CaCO3 whisker specimens presented better crack resistance after L/600 deflection. It is revealed that flexural parameters increase as comprehensive reinforcing index increase. The result showed that the CaCO3 whisker and short PVA fiber provided crack resistance effect at micro-scale and mainly play a dominate role in inhibiting micro-cracking. However, long steel fiber and long PVA fiber showed a better bridging effect of macro cracks at a large deflection.

Published: September 2019

Ese trabajo examina el efecto del origen familiar sobre el tiempo y el tipo de uso de las tecnologías de la información y comunicación (TIC) por parte de los estudiantes españoles. A través de un análisis de la frecuencia y el tipo de uso de las TIC con datos obtenidos directamente de los estudiantes, nuestro estudio ofrece evidencia novedosa del impacto de la educación de los padres sobre el tiempo y el tipo de uso de las TIC para una muestra de estudiantes españoles. Ponemos de manifiesto que un mayor nivel educativo de los padres reduce el tiempo de uso de las TIC por parte del estudiante y, a la vez, aumenta su propensión a utilizarlas con fines educativos. Otro hallazgo empírico de la investigación es que el grado de homogamia educativa en la pareja ejerce un efecto adicional en la variable dependiente.
La distribución del tiempo en los hogares monoparentales de madre ocupada. Vivir con otros como estrategia de conciliación
Authors: Ajenjo Cosp Marc , García Saladrigas Núria
Published: September 2019

Este artículo analiza la distribución del tiempo destinado al trabajo no remunerado —cuidado y tareas domésticas— en los hogares monoparentales de madre ocupada a partir de la Encuesta de Empleo del Tiempo 2009-10. Se parte de la hipótesis de que la madre monoparental ocupada lleva a cabo dos estrategias de conciliación: reorganizar su tiempo y convivir con otros familiares ajenos al núcleo. Los resultados muestran que estas madres dedican el mismo tiempo al cuidado que las biparentales ocupadas, mientras que el tiempo dedicado a tareas del hogar es menor, especialmente en aquellas actividades más arduas, como cocinar o limpiar. Por otro lado, las madres monoparentales ocupadas viven con miembros ajenos al núcleo en una proporción muy superior sus homólogas biparentales. La aportación de estos miembros ajenos al núcleo al trabajo de cuidado es significativamente superior en los hogares monoparentales, algo que no se ha podido demostrar para el trabajo doméstico.

The outcomes of modern technology have turned real-world interaction into a virtual community, then into a cloud one. These giant leaps aided by the excitement created by the possibilities inherent in learning through handheld technologies made using mobile devices in English language teaching (ELT) indispensable. This paper is aimed to deeply overview available handheld technologies and their features that can enable teachers in their mission. It investigates the synergy of a group of mobile devices of smartphones, tablets, iPods, iPads, E-readers, and classroom response systems, among others. These devices have been effective in everyday activities, and are expected to enrich ELT, especially in communities where there is a lack of community of practice (CoP) on the target language. To this aim, this paper was cored around reviewing the potential handheld technologies have in language classrooms. The main data were obtained from the rich body of literature, shedding more light on their properties in creating interactive communication in and out of classrooms. The findings revealed that handheld technologies can be successfully integrated into English language teaching and learning. Pedagogically, teachers are encouraged to exploit mobile devices into their classroom practices after closely testing their specifications, and scanning their advantages and shortcomings.

Rain is an important source of water. The Indian economy is heavily dependent on agriculture and the livelihood of Indian farmer largely depends on rains. The farms are more dependent on rainfall than any other water resource. As we observe there is a lot of climate change in recent years due to industrialization, because of these climate changes there are a lot of floods and droughts. So, it might be helpful to predict the rainfall beforehand and take necessary precautions to protect crops and other sorts of damages that might occur due to the irregular rainfall. So, we present a model that could reasonably predict the future rainfall using very fewer variables. The reason why we developed a model which uses sparse data is that sometimes it could be hard to obtain a large amount of data due to lack or improper working of recording equipment and so on. So, it will be good to have a working model in those situations and applications are implemented.This paper affords a overview of system learning and offers a brief take a look at on distinctive machine gaining knowledge of strategies together with their programs on mobile devices. It also affords an outline of overall performance-associated parameters of gadget studying techniques useful for mobile devices.

Published: September 2019

The development of food and beverage products increases over the years. The high level of food consumption led to the presence of new food and beverage brands produced in Salatiga. In accordance with this fact, Organoleptic Tests or in other words evaluation of food products could be conducted well if the obtained dataset had a complete, rapid, and accurate information. The required information could be clarified into the dataset that was used to calculate the testing. Manually calculating the process was a problem that usually appeared. As a result, losing or having a broken report on the organoleptic test often occurred. Mileage of the research setting became another problem that appeared when the research conducted out of the town, Salatiga. A combination of R&D method and application of algorithm was implemented in this research by using the performed stages. These stages started from the identification of problems to the testing of the systems. During the process of organoleptic testing, Weka 3.8.2 was used as a tool to test the C4.5 algorithm and an implementation of the applied algorithm on the android. The results of this study revealed that the average classification accuracy of the J48 algorithm in Weka could achieve above 90% accuracy and average score of hedonic scaling system was in “agree” category. It also showed that the algorithm and the testing of the systems which implemented on android has a credible performance in classifying data.
