This paper presents a brief modern physics teaching proposal for high school students, with a view to the importance of the use of experiments and simulations. With this is expected to facilitate the teaching and learning of students with respect to modern physics subject, which is not very well seen in high school, is of great importance to the education of the student. I also hope that this work will serve as an aid for teachers in order to view and teaching of modern physics in secondary level schools.

The present research was aimed to study the effect of different levels of inorganic fertilizer N on the yield and yield components of barley varieties at Gorgan Research Station, Iran in 2014-2015 year. A split plot layout within randomized complete block design with 3 replications was used. Main plot were different level of nitrogen fertilizer (35,70 and 105 kg N ha-1) from urea source, and sub plot were different varieties (Line 3, Line 7 and Line 17). Condition represented the effect of nitrogen was significant on feed and grain yield, Protein yield, Plant height, HI. Maximum Plant height, HI and grain yield was recorded in sterling. The highest Feed yield, grain yield was observed in Line 5 variety. Nitrogen applied at the rate of 105 kg N ha-1 resulted in maximum Plant height, Harvest Index, feed yield, grain yield, Protein yield.

Oil is a very critical and essential product to the international community to such an extent that it benefits the globe especially in terms of reserves and production at totally different levels. While the reserves are beneficial to the Southern developing nations of the world, the Northern developed countries are appreciably put at a serious disadvantage in areas that relate to reserves and production of oil. It is however important to note that oil is such a very important product to both the North that is disadvantaged in reserves and production and equally to developing nations that have great reserves and are at advantage in production. It can in fact be asserted that oil is by far much more needed in the developed countries than in developing ones. This is clearly reflected and represented in the consumption levels of developed nations which are by far higher and greater than those in developing nations. In fact to an appreciable extent, the civilization of the western, Northern, developed, technologically advanced countries are strongly attached to adequate and regular supply of oil. Invariably therefore, it has become imperative that those nations strategise at employing new sources of oil supply that will be internal and which will considerably reduce dependence on the outside.

This work examines the circumstance within the Niger Delta, tracing the origins of the crises which currently engulfs the region. Its causes and acknowledging the injustice meted out to the region. It also shows how the activities of groups and individuals have further exacerbated the conditions of its inhabitants as some of the activities being engaged in make it almost impossible to come out of the quagmire or particular note is the effect of oil bunkering, vandalization and kidnapping on the region which has led to a seeming state of anomie. As to the way forward the issue of education, enabling laws such as the Freedom of information, bill and a straightening of the electoral system are advocated as measure to bring us out of the “conflict”-woods” we have found ourselves, preparing us for a time when we do not have to depend solely on oil.

In this paper we optimise the performance of microchannel heat sink with upper flow arrangement of flow at entrance and exit. The performance of micro channel heat sink is directly affected by the pumping power and the thermal resistance. Here we flow from the upper section and optimise to be very low pumping power and thermal resistance. The aspect ratio and the hydraulic diameter of the microchannel are same for flow arrangement. Fluid flow and heat transfer are investigated on the basis of the simulation of the micro channel with number of channel in rectangular shapes. The aim of this work is to get an impression of the physical behaviour in small elements that enable the development of new liquid cooling systems with higher cooling ability and higher effectiveness.

Methods of evaluating the performance of diagnostic tests are of increasing importance in medical science. When a test is based on an observed variable that lies on a continuous scale, an assessment of the overall value of the test can be made through the use of a Receiver Operating Characteristic (ROC) curve. The ROC curve describes the discrimination ability of a diagnosis test for the diseased subjects from the non-diseased subjects. The area under the ROC curve (AUC) represents the probability that a randomly chosen diseased subject will have higher probability of having disease than a randomly chosen non-diseased subject. Semi-parametric being a ROC curve estimation method is widely used in making inferences from diagnostic test results that are at least measurements on ordinal scale. In this paper, we proposed a method of semi-parametric estimation in which predicted probabilities of discordant pairs of observation are obtained from generalized linear mixed model (GLMM) and used in modeling ROC and AUC. The AUC obtained which is time dependent is equivalent to the Mann-Whitney statistic (Hanley and McNeil, 1982) often applied for comparing distributions of values from the two samples.

School burnout is an increasing area of research in the adolescent education literature. The present study extended the literature by focusing on personal variables that can serve as a protective factor against school burnout among students in a rural public university where basic amenities and facilities are lacking. Therefore, the study investigated academic self-efficacy, perceived teacher support, gender and age as factors that predict school burnout. The study was a cross-sectional ex post facto survey that involved 300 undergraduates randomly selected from a public university in southwest Nigeria. The sample comprised 143 males and 157 females, whose ages ranged between 14 years and 34 years (Mean = 22.55; SD = 3.37). Data were collected with a questionnaire made up of four sections that measured the variables of interest in the study. Demographic variables measured were age, sex, and, level of study. Standardized scales that measured school burnout, general self-efficacy perceived teacher support were used to administered on participants. Result showed significant joint influence of academic self efficacy, perceived teacher support, gender and age on school burnout. Academic self efficacy and perceived teacher support had significant independent influence on school burnout.

A large number of studies of flow visualisations, developed on the upper surface of delta or gothic wings and on that of ogives of revolution, have been carried out in the wind tunnel of the Valenciennes University aerodynamics and hydrodynamics laboratory (LAH). These studies have provided a better understanding of the development and the positioning of vortex structures and have enabled, in particular, the preferential nature of inter vortex angles, thereby defined, to be determined on a wide range of Reynolds. This paper concerns in particular the study by visualisations of the behavioural properties on the upper surface of an ogive of revolution having an apex angle of 68.6° at a low angle of attack and conducted at variable speeds. It has been noted that variations in speed have no influence at all on the behavioural properties of the development of vortex structures whereas, by contrast, changes to the angles of incidence do indeed strongly influence that development. The study of the ascent of the vortex breakdown at high angles of attack has revealed original behavioural properties which find expression notably in the discontinuous evolution, in terms of the apex angle, of those angles of attack which define the beginning and the end of the ascent of this vortex breakdown.

We correlated the daily average energy per earthquake for global seismicity within successive 1 M increments (<1.0 to >6.0 M), solar activity as defined by Solar Flux Units (SFU) and a new indices for Reports of Human Conflict Behavior for the years 2009 through 2013 (1,826 days). Events associated with intent (e.g. mobilization) and preparation for confrontation were positively correlated only with the average energy per event for 0.01 to 1 M seismic events and negatively correlated with SFU. The statistical significance of this seismic-behavior correlation was no longer significant statistically if the shared variance with solar activity was first removed. Actual events of force and confrontation displayed the opposite relation (positive correlation with SFU and negative correlation with only earthquake energies in this magnitude range). The shared variance between the behavioural categories and geophysical variables ranged between 4% to 10%. Lag/lead correlations indicated that the daily concordance expanded to about three days before or after the behavioural events. In particular average earthquake energies peaked ~3 days before the behaviors associated with intent for conflict.

English has currently been spoken all over the world, which substantially influences its development. In Bangladesh, English is taught at all levels of education. Moreover, it has become a notion that if a person does have a good command of English, that person is going to get a very good job. To learn English, a learner has to go under a complex process of committing errors. This paper is meant to present how the English variety in Bangladesh has been phonologically and grammatically written and spoken full of errors. This paper reviews errors on grammatical, lexical, and phonological aspects of written and spoken English with theoretical background and procedure of error analysis. It empirically through qualitative and quantitative method finds out the errors in pronunciation, grammar, articles, auxiliaries, and prepositions and also reflects the possible reasons behind the errors in written and spoken English. Finally, it provides some recommendations for effective remedial measures and feedback techniques for developing spoken English in the light of the theoretical and empirical findings of the research.
