In the manufacturing industry among the primary producers of carbon dioxide, cement industry plays one o f the important role. Hence if we reduce the amount of usage of cement in concrete preparation, it will be helpful for a healthy environment. Upon consider the environmental pollution, in the concrete preparation mineral admixtures are used as a partial substitute for cement. Here in this paper, ultra-fine ceramic powder is using as a mineral admixture which are procured from used or broken tiles in 5%, 10% and 15% as level of replacement and also carbon black powder from rubber industry in 1% both by weight of water to made a high strength concrete of M50 grade Concrete. In severe environments like industrial and marine environments, a concrete with high strength may not perform because they are characterized by high chloride content, sulphate content or combination of both. Hence in order to provide such an environment in the laboratory, the specimens are subjected for curing in H2SO4 acid (industrial) and NaCl base (marine). To find the performance of the use of ceramic powder, black carbon powder, compressibility strength and split tensile strength, flexural strength, porosity, corrosion resistance tests are performed.

Published: November 2019

Before diode rectifier (DR) technology for connecting offshore wind
farms (OWFs) to HVdc is deployed, in-depth studies are needed to assess
the actual capabilities of DR-connected OWFs to contribute to the secure
operation of the networks linked to them. This study assesses the
capability of such an OWF to provide communication-less frequency
support (CLFS) to an onshore ac network. It is shown that the HVdc
link’s offshore terminal direct voltage can be estimated from
measurements at the OWF’s point of connection with the DR platform. Two
different methods are proposed for implementing CLFS in the OWF active
power controls. In Method 1, the estimated offshore terminal direct
voltage is used for estimating the onshore frequency deviation. In
Method 2, the actual offshore terminal direct voltage measurement is
used instead. Unique features of the provision of CLFS from OWFs
connected to HVdc via DRs are highlighted, and the dynamic and static
performance of the CLFS control scheme is compared to that of the
communication-based frequency support scheme. To assess the impact of
parameter estimation errors on the provision of CLFS, a parametric
sensitivity study is presented as well, and recommendations are given to
increase accuracy.

Wave and tidal power measurement using HF radar
Authors: Wyatt L.
Published: November 2019

The use of HF radar systems located on the coast to measure ocean surface waves and currents is reviewed. Examples are given showing temporal, spatial and directional variability in the wave and tidal power resource. HF radars are unique in being able to provide such data continuously and over wide areas of sea where marine renewable installations are being considered or already in place. Two projects just getting underway at the time of writing are described. One will use HF radar to provide current and wave data for a French tidal stream power application and the other is aimed at supporting the Welsh Wave Hub site whilst also exploring methods to improve the robustness of the HF radar wave measurements.
Advanced control methods for cross-flow turbines
Authors: Strom B. , Brunton S. L. , Polagye B.
Published: November 2019

Cross-flow turbines have a number of potential advantages for hydrokinetic energy applications. Two novel control schemes for improving cross-flow turbine energy conversion are introduced and demonstrated through scale experiments. The first aims to alter the local flow conditions on the blades through varying blade kinematics as a function of rotational position, thus increasing beneficial fluid forcing. An established method accomplishes this by oscillating the mounting angle of the blade. Instead we proposed to vary the angular velocity of the blade as a function of azimuthal position. Optimizing this controller resulted in a 59% increase in turbine performance over standard controllers. The second control scheme operates an array of two turbines in a coordinated manner to take advantage of periodic wake structures. For a range of relative turbine positions, a parent controller maintains a constant blade position difference between turbines with the same angular velocity. For select positions, the array efficiency is shown to be greater than that of a single turbine. At the optimal position, coordinated control results in a 4% increase in array performance over uncoordinated operation. Finally, intracycle angular velocity and coordinated control schema are combined.
Performance and wake characteristics of a tidal turbine under yaw
Authors: Modali P. , Kolekar N. S. , Banerjee A.
Published: November 2019

In tidal streams and rivers, the flow of water can be at yaw to the turbine rotor plane causing performance degradation and a skewed downstream wake. The current study aims to quantify the performance variation and associated wake behavior caused by a tidal turbine operating in a yawed inflow environment. A three-dimensional computational fluid dynamics study was carried out using multiple reference frame approach using κ-ω SST turbulence model with curvature correction. The computations were validated by comparison with experimental results on a 1:20 scale prototype for a 0° yaw case performed in a laboratory flume. The simulations were performed using a three-bladed, constant chord, untwisted tidal turbine operating at uniform inflow. Yaw effects were observed for angles ranging from 5° to 15°. An increase in yaw over this range caused a power coefficient deficit of 26% and a thrust coefficient deficit of about 8% at a tip speed ratio of 5 that corresponds to the maximum power coefficient for the tested turbine. In addition, wake propagation was studied up to a downstream distance of ten rotor radius, and skewness in the wake, proportional to yaw angle was observed. At higher yaw angles, the flow around the turbine rotor was found to cushion the tip vortices, accelerating the interaction between the tip vortices and the skewed wake, thereby facilitating a faster wake recovery. The center of the wake was tracked using a center of mass technique. The center of wake analysis was used to better quantify the deviation of the wake with increasing yaw angle. It was observed that with an increase in yaw angle, the recovery distance moved closer to the rotor plane. The wake was noticed to meander around the turbine centerline with increasing downstream distance and slightly deviate towards the free surface above the turbine centerline, magnitude of which varied depending on yaw.
Development of a methodology for collaborative control within a WEC array
Authors: Meunier P.-E. , Clément A. H. , Gilloteaux J.-C. , Sofien K.
Published: November 2019

It has been established that Wave Energy Converters efficiency can be improved by control. One of the main challenges of reactive control is the non-causality of the optimal controller. This study presents a methodology to solve the non-causality issue by providing a deterministic forecast of the controlled body velocities. This forecast is achieved by using the measurements of the states of the most up wave device of the array. The reactive control approach also implies strong instabilities due to the extreme dynamics of the controlled devices. The proposed method suggests to mitigate this behavior by applying a window function on the optimal controller impedance. In order to maximize the efficiency of the resulting control and ensure the robustness of the system, a stability analysis is conducted. Optimal sets of parameters are determined and applied to a time domain simulation of an array of 10 cylindrical floating WECs. The results obtained show an average efficiency of the array of 83% of the maximum energy retrievable in the waves.

Kodagu is the smallest district of Karnataka. It is considered as the Switzerland of the East and
Kashmir of India. The district is basically an Agro-based economy. It is the second largest producer of coffee
of the country and now added with eco-tourism because of its scenic beauty.
Kodagu doesnot have any large scale industries but only agro based and MSME sector. It is because
of its topography and climatic conditions. One such micro sector was the “Grinding stone production of the
Paloor Village of Madikeri Taluka of the district. The grinding stones of this village was very famous not only
in the district but also in the nearby districts like Mangaluru, Mysuru and also Bengaluru. The production was
gradually decreasing and since two years it has come to a standstill due to lack of demand.
Not only the stone grinders but also some of other rural enterprises are in the verge of fading away.

Published: November 2019

According to official statistics, the food industry is characterized by high rates of injury. An important role in preventing occupational injuries is played by the analysis of the causes and circumstances of accidents and, first of all, the bringing of its results to all structural units and employees. The purpose of the article is research and evaluation of industrial hazards during the operation of food industry equipment, scientific substantiation of priority directions of the prevention of traumatism at food enterprises. On the basis of the data of the special investigation of accidents at the Ukrainian industry, an injury analysis was conducted at food industry enterprises. Identified hazardous factors in the operation of food industry equipment. It has been determined that more than a third of injured people were injured when using cars. The second position is accidents related to technological equipment for the food, meat, dairy and fish industry. The main types of events that resulted in injuries include traffic accidents, including traffic accidents on public roads (roads) and on the territory of the enterprise, the effect of moving objects, flying, turning and falling of the victim. The state of professional training in the field of occupational safety of the victims was investigated. Distribution of accidents on causes of occurrence taking into account types of productions has been carried out. It was found that the most traumatic are the production of dairy products and the production of bread, bakery and flour products. The areas of injury in both types of production are: violations of traffic safety rules, violations of labor and production discipline, including non-fulfillment of official duties, requirements of instructions for occupational safety, unsatisfactory technical condition of industrial objects, buildings, structures of engineering communications, territories, means production, vehicles. In order to prevent injuries among food industry workers it is expedient: to provide the proper technical condition of production equipment; to strengthen control over the observance of the requirements of the technological process, the rules of labor protection in the performance of work of increased danger; to ensure the availability of modern means of individual and collective protection and to strengthen control over their use; to implement effective methods of teaching safe working methods.

Mechanical complications resulting from myocardial infarction usually have profound acute or chronic hemodynamic effects. Left ventricular aneurysm formation and ventricular septal rupture occurs in 10-20% patients after acute myocardial infarction [1-6]. Surgical techniques have gradually evolved since the first successful operation for post-infarct ventricular septal defect was performed by Cooley and colleagues in 1956 [2,3,6].

Introduction: Phenylephrine is an alpha-agonist with vasoconstrictor effect. Systemic absorption or adverse reaction can cause complications that can be lethal. In those cases of adverse drug reactions with failure to conventional management, the use of ECMO has been reported as a treatment modality.

Clinical case: We report the case of a 13 years old teenager, who presented acute pulmonary edema and acute heart failure subsequent to the application of topical phenylephrine during the a rhino-septoplasty procedure, and that warranted placement of ECMO due to failure of conventional treatment.

Discussion: Venoarterial ECMO was placed by central cannulation, with ventilatory and hemodynamic improvement, performing the explant successful 4th postoperative day.

Conclusions: ECMO as a "bridge to recovery" may be an alternative in those cases of pulmonary or cardiac failure and refractory with a poor response to conventional treatment, as well as an option to save the life of these patients.

Published: November 2019

This study aimed to investigate the facilitative effect of observational practice combined with mental imagery on learning of soccer dribbling. 140 young boys with the average age of 14,52 (±2,96) and mental imagery score of 48,69 (±5,1), who were unfamiliar with the research task, voluntarily participated in this study. The participants were assigned to homogenous groups according to their pre-tests results as follow: 1- physical practice; 2- observational practice; 3-mental imagery practice; 4-physical-observational practice; 5-physical-mental imagery practice; 6- observational-mental imagery practice and 7- physical-observational-mental imagery practice. Then the participants completed three sessions including ninety trials. At the end of the final training session, an immediate retention test was conducted that followed by a delayed retention test after 48 hours. The results of One-Way ANOVA test indicated that in both immediate and delayed retention tests, the physical-observational-mental imagery group and the physical group had a better performance compared with other groups (p<.05). Furthermore, the combined physical-mental imagery group obtained higher scores in soccer dribbling task in comparison with the combined physical-observational group. The findings support the beneficial effects of cognitive interventions as well as physical practice.

Published: November 2019

The aim of this research is to analyse the different representational levels reached both by elite/non-elite gymnastics with different levels of experience when performing a specific motor task (handstand). We will be focusing specifically on how these representations become more explicit and conscious as the development process takes place. These increasing levels of awareness will allow the subjects of our study to have greater control over their actions. The relationship between awareness and motor learning is a question that has not drawn much attention so far, but it is essential from both, a theoretical and a practical point of view. Indeed, our interest in this issue springs out not only from psychological concerns but also from our connection with teaching and learning of Sport.

Objective: The aim of the current study was to investigate the effects of sensorimotor integration activities on the static and dynamic balance skills of trainable little boys with Down syndrome.

Materials and Method: In this quasi-experimental study, the purposive and convenience sampling methods were used to select 20 children (aged 8.50±1.60 years old). Then they were randomly divided into the experimental and control groups, each of which had 10 subjects. The modified stork test and the Timed Up and Go test (TUG) were conducted to evaluate the static and dynamic balance skills, respectively. The experimental group received 50 forty-minute training sessions six times a week. In the control group, the subjects used the class training programs. The independent t-tests were carried out to analyze data at 0.05 significance level.

Conclusion: The results indicated that sensorimotor integration activities improved static and dynamic balance skills.
1,5-Phosphonium betaines from N-triflylpropiolamides, triphenylphosphane, and active methylene compounds
Authors: Fiore Vito A , Freisler Chiara , Maas Gerhard
Published: November 2019

N-Phenyl-N-(trifluoromethylsulfonyl)propiolamides react with triphenylphosphane in the presence of various active methylene compounds CH2XY in a 1:1:1 molar ratio to furnish 1-phosphonium-5-oxabetaines, Ph3P+–C(R)=CH–C(O–)=CXY. These betaines are formed preferentially, but not exclusively, as E-diastereoisomers with respect to the vinylic double bond. In some cases, separation of the two diastereoisomers was achieved by fractionating crystallization. Structure determination by X-ray diffraction analysis revealed marked conformational differences around the CH–C(O–) single bond of E and Z-isomers and extended charge delocalization in the anionic part.

L’art politique et sa visée téléologique
Authors: Michel Karine
Published: November 2019

Cette étude se propose d’interroger la manière dont les penseurs musulmans de l’époque classique ont produit une science politique qui se veut être un art pratique, ayant une visée téléologique : le bonheur. À travers les pensées de Farabi, Miskawayh ou en encore du Kitāb al-Sa‘āda wa l-Is‘ād (pseudo al-‘Āmiri), s’est constituée toute une réflexion politique prenant racine dans les champs biologique, noétique et éthique. Du fait de la composition de l’homme en corps et esprit, l’association civile devient la condition nécessaire à l’atteinte du bonheur par l’homme. Le bonheur n’est plus seulement la félicité ultime promise dans l’au-delà mais bien un bonheur terrestre, hic et nunc .
Le gouvernement selon Avicenne
Authors: Sebti Meryem
Published: November 2019

La conception avicennienne de la politique est indissociable de sa doctrine de la providence divine et de sa prophétologie. Ce travail examine les implications de cette doctrine à travers l’étude du dernier livre de la Métaphysique du Šifā’ d’Avicenne, qui est le texte le plus complet du philosophe sur l’ordonnancement de la cité, sur ses lois et sur la nature du nomothète. Nous nous attachons à répondre à la question suivante : puisque la providence divine s’étend jusqu’au confins de la société des hommes par la médiation du prophète et de la loi révélée, y a-t-il encore une place pour une science qui, telle la politique, cherche à poser les fondements d’un ordre proprement humain ?
