A novel method to achieve high yield of total RNA from zebrafish for expression studies
Authors: Shukla Saurabh , Jhamtani Reena C. , Dahiya M. S. , Agarwal* Rakhi
Published: May 2017

Gene expression studies require high-quality intact total RNA for real-time PCR analysis. A degraded or impure sample can provide disastrous results in the downstream process. RNA is very unstable and can be contaminated easily by ribonuclease (RNase), therefore utmost quality control checks are required to ensure high quality RNA. Herein, we have come out with a protocol to isolate total RNA from liver, kidney and brain of adult zebrafish using a commercially available chemical denaturant and subsequent clean-up to remove traces of DNA and impurities. Kidney tissue give maximum yield of total RNA concentration i.e. 135.8786 ng/µL. The whole procedure was performed twice with an absorbance ranging from 1.9 to 2.0 observed in all samples. Throughout these procedures there are numerous quality control checks to ensure that the sample is not degraded or contaminated.

WHATEVER ELSE HISTORY may have to say about the mid-twentieth century, it will record that it was a period of enormous growth in the ability of human beings to move large quantities of messages almost instantaneously. The Science Council of Canada reports that while our energy capacities have increased 1,000 times in the past centun and our weaponry capabilities 1,000.000 times. our communications capacities have increased 10.000.000 times. The great inventions and technolopcal advances of our age have been almost exclusively concerned with the movement of information -images and words over distance. And the rate of invention has increased geometrically since the first telegraph message was sent in 1844. The diagram on the following page conveys something of the way communications developments have been coming in rapid succession over the past decades.

This September, the second national conference of independent video producers, entitled "The Fif th Network, was held in Toronto. Most of the participants had attended the first conference in Vancouver in 1973; many had extensive experience not only in producing video but also in the often fruitless negotiations with cable operators and the CRTC in attempting to get those programnes before a viewing public. Almost everyone present was a veteran of numerous government projects funded to "use video as a catalyst for social change" or a "tool for comnunity animation". No one had much tolerance for further rhetoric as a result.
The Mass Media and Convention Voting Behaviour

Published: May 2017

Although there has been considerable research1 on the impact of the mass media on voting behavior, the results appear to be contradictory.2 Explanations such as selective exposure3 or peer group influence4 are cited as mediating influences. But the problem of measuring the role of the mass media in the determination of voting choice is indicative of a more general malaise in communication research. W. Phillips Davidson and Frederick T.C. Yu argue that the field has grown so large that it lacks unifying theoretical direction and that researchers concentrate on disparate, and often picayune, problems.

The Daily Newspaper: Mirror Of Our Myths
Authors: De Repentigny Michel
Published: May 2017

The object of this paper is to demonstrate that if it can be said, as a general rule, that Quebec's daily newspapers - and this observation is no doubt true also of Canadian and American dailies - do not grant news or information from the Third world much importance, it should not be taken for granted that trying to improve this situation will contribute significantly to the advent of a new world order of information, that it will do justice to the real and huge problems hindering the production and circulation of information in developing countries.

Obviously, the commercial aspects of the news market in Western countries bear heavily on the 'social vocation' of newspapers. The intimate structural ties between these two orders of necessity are such that not much can be done to have newspapers offer their readers, in a sustained way, instructive information on the development processes of the Third world instead of supplying, often in a haphazard way, news which entertains or shocks.

A realistic approach, then, to these problems requires that a basic fact be taken into account: namely that what is most urgently needed in Third world countries are infrastructures that could generate and disseminate information horizontally among their inhabitants and those of other underdeveloped countries; much more so, it seems to me, than a more balanced flow of news between North and South. Concretely, this implies that it is more important for people living in remote Senegalese villages to be adequately informed about agricultural techniques suited to their specific needs, than for me to be informed by a news dispatch coming from an African news agency, that Senghor has just published a new collection of poems.
Existing Decision-Making Practices on Daily Newspapers in Canada
Authors: Joseph Ted
Published: May 2017

Reporter alienation is evident in some Canadian daily newspaper newsrooms.1 One of the reasons for the alienation could be the traditional autocratic bureaucratic environment where management makes most decisions and simply excludes reporters from meaningful participation in decision-making. One classic solution to eliminating such alienation, according to social psychologists Argyris, Maslow, Likert and McGregor, is decentralization.2 Such increased participation in decisions will, say these theorists, increase the mental health of most individuals and the organizational health.
Editorial Notes
Authors: Beattie Earle
Published: May 2017

As we go to press in the first month of 1982, the Canadian Journal of Communication reflects that it has been publishing regularly for eight years, counting the career of its predecessor, Media Probe. For four of these years it has been the Journal serving largely an academic audience. In the process, it has barely hung on financially. But with assistance from York University and some of its units, one short-lived outside grant and from members of the Canadian Communication Association and non-member subscribers, we have managed to pull through. The Journal was the official publication of the CCA for two years, but it is now independent of that body, although affiliated with it in the way of providing subscription at a reduced rate with membership.
A Biographical Tribute to Earle Beattie on his Retirement as Editor
Authors: Parker Edward
Published: May 2017

It was 1935 when the two of us met as "young Turks" in the depression-ridden prairie city of Winnipeg. Earle Beattie had come from Vancouver a few years before and at the age of 14 began writing articles and fiction for the Young Authors Section of the Free Press. Writing and editing came easily to him. He was writing a column by the age of 16 and became an assistant editor for the Section, following graduation from high school. He had become a moving spirit among amateur writers in Manitoba and his first paid job as a reporter for the Free Press was reviewing plays and shows around town. Later, he went to United College (now the University of Winnipeg) and became a college correspondent for the Free Press at 20 cents a column inch. I did the same for the Winnipeg Tribune and there was lively competition.
Comments from the New Editor
Authors: Tate Eugene
Published: May 2017

The CANADIAN JOURNAL OF COMMUNICATION has grown over the past eight years as the discipline of Communication has developed in this country. The weaknesses of the Journal are, I believe, attributable to the weaknesses of the discipline of Communication in Canada. Our discipline is slowly developing in this country. Until three years ago there was no organization to give it focus or to bring us all together. Communication studies were being conducted under many rubrics with research being published in many different learned journals. If the Journal has had an identity crisis it is because there has been no single orientation which could focus the discipline in Canada.
Strike Talk: A Case Study of News
Authors: Knight Graham
Published: May 2017

This article presents an exploratory analysis of strike news as reported by two Toronto dailies during the 1980 postal strike, in light of a number of recent British studies of industrial relations news (Beharrell and Philo, 1977; Clarke and Taylor, 1980; Connell, 1979; Edwards, 1979; Glasgow Media Group, 1976, 1980; Hartmann, 1975-6; Morley, 1976). These studies point to the way in which industrial relations news is framed so as to draw upon and reproduce certain dominant assumptions and beliefs about the nature of social reality. In this respect, they bear closely upon other recent conceptualizations of news as 'ideology1 (Fishman, 1978, 1980; Gitlin, 1980; Hall et al., 1978; Tuchman, 1978). This concept avoids the overly empiricist and psychologically reductionist limitations of the conventional idea of news 'bias' by viewing the form and content of discourse as socially determined, as the structural outcome of cross-cutting relations of power. The implication is that discourse remains partial in the sense that what is included stands in usually silent relation to what is excluded, viz. alternative ways of seeing and knowing the world. Thus, news accounts may be unbiased and balanced but nonetheless ideological in that they are bounded unwittingly and uncritically by assumptions about what is newsworthy in particular and credible knowledge in general.

Promoting use of Solar energy using Smart Meter
Authors: Gupta Anant , Tasgavkar Imran , Murali Pranav , Jain Utsav , Bhatia Gresha
Published: May 2017

Energy has become a detrimental factor for survival and progress of anthropology. For the past decade, we have become totally dependent on  unlimited and continuous supply of  electrical energy. However, the generation of such huge amount of electrical energy is done from nonrenewable sources of energy like coal, oil gas etc. This way of producing electricity involves heavy consumption of non-conventional sources of energy and has given rise to the ominous problem of global warming. Thus, energy conservation has become an important concern all over the world. Switching to the use of renewable sources like solar, wind and hydro energy  has become a recent trend. This is the reason why our project, aims to maximise the use of solar energy by analyzing the present system such that it can be beneficial for the economy of our country. The analysing process is done using the smart meter, which captures the readings on an hourly basis.
Network Intrusion Detection System Using C4.5 Algorithm

Published: May 2017

There is a great concern about the security of computer these days. The number of attacks has increased in a great number in the last few years, intrusion detection is the main source of information assurance. While firewalls can provide some protection, they fail to provide protection fully and they even need to be complemented with an intrusion detection system (IDS). A newer approach for Intrusion detection is data mining techniques.IDS system can be developed using individual algorithms like neural networks, clustering, classification, etc. The result of these systems is good detection rate and low false alarm rate. According to a recent study, cascading of multiple algorithms gives a way better performance than single algorithm. Single algorithm systems have a high alarm rate. Therefore, to solve this problem, a combination of different algorithms are required. In this research paper, we use the hybrid algorithm for developing the intrusion detection system. C4.5 Support Vector Machine (SVM) and Decision Tree combined to achieve high accuracy and diminish the false alarm rate. Intrusions can be classified into types like Normal, DOS, R2L and U2R.Intrusion detection with Decision trees and SVM were tested with benchmark standard NSL- KDD, which is the extended version of  KDD Cup 1999 for intrusion detection (ID).

Glucagon-Like Peptide 1 Receptor Activation Augments Cardiac Output and Improves Cardiac Efficiency in Obese Swine After Myocardial Infarction
Authors: Sassoon Daniel J. , Tune Johnathan D. , Mather Kieren J. , Noblet Jillian N. , Eagleson Mackenzie A. , Conteh Abass M. , Sturek Joshua T. , Goodwill Adam G.
Published: May 2017

This study tested the hypothesis that glucagon-like peptide 1 (GLP-1) therapies improve cardiac contractile function at rest and in response to adrenergic stimulation in obese swine after myocardial infarction. Obese Ossabaw swine were subjected to gradually developing regional coronary occlusion using an ameroid occluder placed around the left anterior descending coronary artery. Animals received subcutaneous injections of saline or liraglutide (0.005–0.015 mg/kg/day) for 30 days after ameroid placement. Cardiac performance was assessed at rest and in response to sympathomimetic challenge (dobutamine 0.3–10 μg/kg/min) using a left ventricular pressure/volume catheter. Liraglutide increased diastolic relaxation (dP/dt; Tau 1/2; Tau 1/e) during dobutamine stimulation (P < 0.01) despite having no influence on the magnitude of myocardial infarction. The slope of the end-systolic pressure volume relationship (i.e., contractility) increased with dobutamine after liraglutide (P < 0.001) but not saline administration (P = 0.63). Liraglutide enhanced the slope of the relationship between cardiac power and pressure volume area (i.e., cardiac efficiency) with dobutamine (P = 0.017). Hearts from animals treated with liraglutide demonstrated decreased β1-adrenoreceptor expression. These data support that GLP-1 agonism augments cardiac efficiency via attenuation of maladaptive sympathetic signaling in the setting of obesity and myocardial infarction.
Intramyocellular Ceramides: Subcellular Concentrations and Fractional De Novo Synthesis in Postabsorptive Humans
Authors: Chung Jin Ook , Koutsari Christina , Blachnio-Zabielska Agnieszka U. , Hames Kazanna C. , Jensen Michael D.
Published: May 2017

We investigated the relationship between insulin resistance markers and subsarcolemmal (SS) and intramyofibrillar (IMF) ceramide concentrations, as well as the contribution of plasma palmitate (6.5-h infusion of [U-13C]palmitate) to intramyocellular ceramides. Seventy-six postabsorptive men and women had muscle biopsies 1.5, 6.5, and 24 h after starting the tracer infusion. Concentrations and enrichment of muscle ceramides were measured by liquid chromatography-tandem mass spectrometry. We found that HOMA of insulin resistance, plasma insulin, and triglyceride concentrations were positively correlated with SS C16:0 and C18:1 ceramide, but not SS C14:0-Cer, C20:0-Cer, C24:0-Cer, and C24:1-Cer concentrations; IMF ceramide concentrations were not correlated with any metabolic parameters. The fractional contribution of plasma palmitate to 16:0 ceramide was greater in SS than IMF (SS, 18.2% vs. IMF, 8.7%; P = 0.0006). Plasma insulin concentrations correlated positively with the fractional contribution of plasma palmitate to SS 16:0 ceramide. The fractional contribution of plasma palmitate to intramyocellular SS 16:0 ceramide was positively correlated with SS C16:0 ceramide concentrations (γ = 0.435; P = 0.002). We conclude that skeletal muscle SS ceramides, especially C16 to C18 chain lengths and the de novo synthesis of intramyocellular ceramide from plasma palmitate are associated with markers of insulin resistance.

An existing renewable energy source within our territory which has not been massively introduced is the low power wind energy. This kind of installations has only been used for electricity generation in off-grid systems. This paper describes a pilot scheme in which five 5kW wind turbines will be installed in the Municipality of Las Palmas de Gran Canaria. The first stage has consisted on the determination of the wind potential within the Municipality of Las Palmas de Gran Canaria, which has been determined taking as a reference the data from the study performed by the AEMET (Spanish Meteorological Agency) and the data comprised in the Canary Islands Wind Resource Cartography. Once this has been done, a study of physical variables related to the wind flux over the Canaries has been performed by taking data generated by a computer simulation of weather conditions in the course of a year. After the calculation of the eolic data and after the selection and location of the five turbines has been determined, a description of the turbines to be installed is given along with an overview on the territorial legal framework applicable to this type of installations.

The exact knowledge of the grounding system impedance, including its expected variability, is a matter of paramount importance in the design of medium and high voltage infrastructures. The principles underlining the physical processes involved in grounding are well established and so are the engineering concepts regarding safe operation of the grounded systems. Quite a few theoretical expressions are widely used in the project stage of any installation. Unfortunately, these expressions are only valid for simple geometries and simplified material characteristics. Uncertainty arise from the intrinsic complexity of the grounding environment: buried grids and rods, reinforced concrete foundations surrounding them, weather dependent and non-uniform soil characteristics, etc To overcome these limitations, in this paper the finite element method is applied to obtain the grounding impedance and the potential distribution around a real grounding system excited with sinusoidal currents at several frequencies. Additionally, for validating purposes, a single vertical ground rod has been simulated and compared with the results obtained by other authors. FEM commercial software, in addition to some specific purpose user functions, has been used. The method presented in this paper can be applied to any real geometry, electrode configuration and type of soil.

Electricity demand forecasting is important for utilities and for some costumers. It allows to balance energy production and consumption. From the costumer point of view, it is essential for efficient operation, sizing of installation, maintenance scheduling, to name just a few. Load forecasting is a difficult task and there are many tools available to perform it. Among them, Artificial Neural Networks are receiving a lot of attention because it is not needed to know any relationship between the involved variables. But, they are constructed as black boxes, what is one their drawbacks. In this paper, some results of the load demand forecasting of a hospital are shown. It is important the previous statistical analysis of the load curves and how the results are improved adding new information to the training data set, as maximum and minimum daily temperatures.

Outdoor air temperature range in the Baltic region is below average values in Europe. Range of outdoor air temperature in the Baltic region is -3 ºC in winter and +16 ºC in summer. And solar radiation intensity is lower in comparison with the average European values. The average solar radiation intensity reaches 1100 kWh/m2 per year in Baltic region. Therefore, there is a particular need to optimize the solar thermal system in the Baltic region. Solar collector’s operation methods investigated on the IPE solar energy polygon according different parameters. The most common types of solar collector’s operation were investigated and compared: by the time, by the heat carrier temperature differences of input and output, by the solar radiation intensity and operation control methods in various combinations. Theoretical and practical advantages and disadvantages of using each control methods were analyzed. Solar collector’s operation system could be regulated in accordance with the solar radiation intensity, by the boiler lower temperatures and by the outdoor air temperature to determine precisely the solar collector efficiency of the parameter changes. This may help to avoid the previous operation systems testing regime deficiencies. The precision of solar collectors operation depends on the type of operation systems: heat losses and the collector efficiency calculation accuracy, the sensor is accuracy, the time between the regulation regimes, and the range of heat carrier pumps action operation sensors. Currently, companies that offer solar collectors, offer solar collectors complete set with all necessary equipments for the solar collector connection for hot water supply system, or for home heating operation system by the temperature difference of input and output. And no one of them does not offer solar collectors operation systems by the various parameters.

Authors: Hamdy HASSAN  , Souad HARMAND
Published: May 2017

A three dimensional numerical model for the cooling of an electronic component by using a flat heat pipe (vapor chamber) is presented. The heat pipe consists of two copper flat walls, two copper water wicks and a vapor region sandwiched between the heat pipe wicks. In this paper, a three dimensional hydrodynamic model of the wicks and vapor regions coupled with a three dimensional thermal model of the heat pipe is presented. The hydrodynamic model of the wick and vapor region is obtained by solving numerically the mass, momentum and liquid vapor interface conditions in a three dimensional form. The temperature of the model is obtained by coupling the energy equation in a three dimensional form with the hydrodynamic model. The model are solved numerically by using finite difference method. The results illustrate well the function of the heat pipe and the circulation of the working fluid inside the wick regions. They also shows that ,for power input 107 W, the maximum liquid velocity is about 4.35×10-4 m/s

INTERCONNECTION OF A PHOTOVOLTAIC GENERATOR (PVG) TO A MAIN SUPPLY: A SIMULATION STUDY
Authors: Maamar Taleb
Published: May 2017

This paper presents a technique for interconnecting a photovoltaic generator (PVG) to a main supply of AC nature. The technique uses a single phase full wave bridge rectifier. Such bridge rectifier is operated in an inverter mode of operation. and that is to guaranty its contribution of real power to a main AC supply. The bridge rectifier is also operated in such a way that its control circuit (i.e triggering circuit) is self adjusted when extracting the maximum power from the PVG and injecting such power into to the main AC supply. The proposed technique has been formulated by a MATLAB/SIMULINK model. The simulation of the developed simulink model shows for a certain pre-defined AC load that up to 66.39 % of the power required by an AC load is obtained from the PVG source. The remaining 33.61 % of power required by the AC load is provided by the main AC supply. The Simulink model shows also that nearly 99.14 % of power can be extracted from the PVG source at a certain pretended solar radiation level (i.e insolation level).

Published: May 2017

This paper presents a battery response analyzer for high current levels. This system represents a very useful method to characterize simple battery and supercapacitor models, which commonly aid designers in the DC-DC converter development for electric vehicles (EV). A DC-DC converter is used to discharge batteries at a controlled current. The current is governed by a control unit which imposes a 100A pulse signal for the device under test (DUT). The response for the discharge pulse current is evaluated and then, a simple battery model is extracted. A complete low-cost test bench was developed in order to extract experimental data from batteries and super capacitors. Obtained measurements include high current pulse analysis and charge/discharge cycle to study the ageing of the device.

Some Power Quality Issues in Hospital Facilities
Authors: M. I. Buzdugan  , H. Bălan
Published: May 2017

The present approach focuses on some specific power supply and power quality issues in hospital environment. This environment is always a special one and changes dramatically one day after another, due to the last decade boom of biomedical engineering. The authors’ opinion is that in medical facilities, one should go beyond the standard EN 50160, on voltage characteristics of electricity supplied by public electricity networks, taking also into account the standard EN 60601 on general requirements for safety on medical electrical equipment and the related standards on electromagnetic compatibility. Otherwise, a power quality analysis should result in the unpleasant situation in which products designed and placed on the market according to all relevant legal and product standard requirements, may become unsafe or even be damaged due to a supply voltage consistent only with the standard EN 50160. The paper depicts a relevant case study analyzed in the intensive care department of the Emergency County Hospital from Cluj-Napoca, Romania
