Authors: Mostafa Harby , Sultan Wael 
Published: March 2018

Abstract
Drip irrigation systems have become a major part of developing agriculture in Egypt and the aim of this research was to obtain the best performance from irrigation systems management using locally modified and original emitters. The experiments were carried out at the National Irrigation Laboratory of the Agricultural Engineering Research Institute. The emitters were tested and calibrated under different operating pressures (0.50, 0.75, 1 and 1.25 bar) to determine emitter flow rates and emitter emission uniformity (EU) and manufacturing variation coefficient (CV). The original emitter performance was determined using the relationship between emitter flow rate (2 lh−1) and operating pressure, with data indicating that the EU was 98.5%, at a CV of 2.3% and actual flow rate was 1.8 lh−1 for the original emitter. The EU was 93.8% with a CV of 5.2% and actual flow rate of 2.02 lh−1 for the modified emitter. For original emitter performance at 4 lh−1, data indicated that the EU was 96%, with a CV of 4.8% and actual flow rate of 3.78 lh−1. The EU for the modified emitter was 95% with a CV of 2.7% and actual flow rate of 4.5 lh−1. The emitter exponent values were 0.41 to 0.44 for modified and 0.37 to 0.38 for original emitters.

Published: March 2018

SUMMARY

Objective:
To evaluate the effects of different mold materials, their diameters, and light-curing units on the mechanical properties of three resin-based composites (RBC).

Methods and Materials:
A conventional nano-filled resin composite (Filtek Supreme Ultra, 3M Oral Care, St Paul, MN, USA) and two bulk-fill composites materials, Tetric Evoceram Bulk fill (Ivoclar Vivadent, Schaan, Liechtenstein) and Aura Bulk Fill (SDI, Bayswater, VIC, Australia), were tested. A total of 240 specimens were fabricated using metal or white semitransparent Delrin molds that were 4 or 10 mm in diameter. The RBCs were light cured for 40 seconds on the high-power setting of either a monowave (DeepCure-S, 3M Oral Care) or polywave (Bluephase G2, Ivoclar Vivadent) light-emitting diode (LED) curing unit. The depth of cure was determined using a scraping test, according to the 2009 ISO 4049 test method. Data were analyzed using multivariate analysis of variance followed by Tukey multiple comparison test (p&lt;0.05).

Results:
In general, when used for 40 seconds, both LED curing lights achieved the same depth of cure (p=0.157). However, the mold material and its diameter had a significant effect on the depth of cure of all three RBCs (p&lt;0.0001).

Conclusion:
Curing with either the polywave or monowave LED curing light resulted in the same depth of cure in the composites. The greatest depth of cure was always achieved using the 10-mm-diameter Delrin mold. Of the three RBCs tested, both Tetric Bulk Fill and Aura achieved a 4-mm depth of cure when tested in the 10-mm-diameter metal mold. Tetric Bulk Fill was the most transparent and had the greatest depth of cure, and the conventional composite had the least depth of cure. Very little violet (&lt;420 nm) light penetrated through 6 mm of any of the RBCs.

Published: March 2018

Aims
The aim of this study was to compare precipitants, presenting symptoms and outcomes of patients with heart failure and mid-range ejection fraction (HFmrEF), heart failure and preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF) in an Australian cohort.

Methods
We divided 5236 patients in the Management of Cardiac Failure program in Northern Sydney Australia, into HFmrEF (n = 780, 14.9%), HFpEF (n = 1956, 37.4%) and HFrEF (n = 2500, 47.8%), using a cutoff left ventricular ejection fraction of 40–49, at least 50 and less than 40%, respectively.

Results
For most characteristics, the HFmrEF patients were intermediate. Hypertension among the HFrEF, HFmrEF and HFpEF groups was present in 50.6, 61.7 and 68.9%, respectively; age more than 85 years was present in 35.1, 37.6 and 42.2%; atrial fibrillation in 35.3, 44.2 and 49.9%; and elevated serum creatinine (>100 μmol/l) in 59.2, 55.6 and 51.0%. For ischemic heart disease and ischemia as a precipitant of admission, HFmrEF patients were similar to the HFrEF group, and more common than in HFpEF. Mortality rates were not significantly different between the three groups. Readmission rates were highest for HFpEF (40.2%), followed by HFmrEF (42.4%) and HFrEF (45.4%), largely due to differences in nonheart failure readmission.

Conclusion
Clinically, HFmrEF represents an intermediate phenotype, with the exception of resembling HFrEF with a higher incidence of ischemic heart disease.
Macroeconomic Dynamics and the Manufacturing Output in Nigeria
Authors: Onakoya Adegbemi Babatunde 
Published: March 2018

AbstractThis paper examined the impact of the changes in the macroeconomic factors on the output of the manufacturing sector in Nigeria from 1981 to 2015. Preliminary evaluation of the data was conducted using both descriptive statistics and stationarity evaluation. The test indicated that not all the variables are normal. The occurrence of order integration at first level difference necessitated the deployment of the Johansen cointegration test. The findings revealed no short run association among manufacturing output and each of GDP, exchange rate, broad money supply and unemployment rate. Negative relationship existed amongst inflation rate, interest rate, exchange rate, broad money supply on one hand, and manufacturing output. The inflation rate and interest rate, were statistically insignificant. However, significant and positive relationship existed between GDP of the previous year and unemployment on the one hand and manufacturing output on the other, at 5 percent level. The results showed that manufacturing was a veritable engine of economic growth. The post estimation tests showed presence of serial correlation but evidence of heteroscedasticity existed which, made the model inefficient, but its estimator is still unbiased. The study recommended the harmonization of both fiscal and monetary policies for the attainment of macroeconomic stability and avoidance of rapid policy summersaults.

Abstract
This paper discusses the issue of the specificities of the relationship of the comparative and the historical methods in the research of political history. We find examples of the relationship of the comparative and the historical methods in the research of political history in works of modern historiography. Contemporary political history studies various forms of political reality, a variety of themes and those subject to fad, like other branches of history. The analysis has shown that all general scientific methods, particularly the historical method, as well as the comparative method, enable the scientific cognition of social, historical and political phenomena and processes, which also applies to the research of political history.
Global Volatility Spillover, Transaction Cost and CNY Exchange Rate Parities

Published: March 2018

AbstractThe present study examines the intertemporal association between CBOE market volatility indices (VIX), foreign exchange rates and respective bid-ask spread for four CNY exchange rate parities. For this purpose, the study utilizes the stylized EGARCH (1, 1) model for the period of 2011 to 2016. Results report that negative slopes of EUVIX, BPVIX, and JYVIX imply a higher level of volatility, hence improves the underlying exchange rate through appreciation, while positive slopes of VXFXI deteriorates exchange rates during the sample period. Similarly, high volatility widens bid-ask spread which, in turn, deteriorates respective exchange rate and vice versa. The market-oriented policies of China increased the forecasting capability of options volatility indexes to anticipate exchange rate dynamics from 2% to 5%. This indicates that flexible exchange rate regimes lead to increase the predicting power of micro structural components. Assessments of Post-reforms in CNY exchange rate evidence the rise in volatility in financial markets of China, which may discourage investor confidence and seeks for ‘flight to safety’ effect. While, low volatility reduces bid-ask spread which improves underlying exchange rate. The level and variance estimates of exchange rates and spreads reveal that there exists a significant relationship with VIX indices which implies that GARCH forecasts outperform in anticipating future volatility. The volatility estimates of variances show the persistence of volatility and absence of leverage effect. Overall, this article suggests that VIX index can act as ‘fear gauge’ indicator and its potential direction may guide investors in anticipating the movements of CNY exchange rate parities. Moreover, outcomes provide imperative implications to monetary and financial institutions for policy framing.

Published: March 2018

The aim of this research is to know the relationship between lemuru fish catch to Sea Surface Temperature (SST), El-Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) phenomenon in Bali Strait. The results showed, that in the period 2007 – 2016. fluctuations of catches lemuru tends to decline. Sea Surface Temperature (SST) distribution with the lowest temperature 25,28oC at 24,53oC - 27,16oC and the highest temperature is 29,31oC in the range of 28,730C – 30,490C. The lowest temperature occurred in July - September while the highest temperature occurred in January - April. Based on the calculation there is a linkage and relationship between catch and SST as shown on the value of determination and correlation reached 50,0% and 70,73%. Most of the catches occurred in the west season and then the transition II, transition I and East Season. The relationship of ENSO phenomenon to the catch during the El-Nino phase of lemuru catch will increase while in the phase of La-Nina the catch of lemuru will decrease, because time of El-Nino phase of the sea surface temperature (SST) relative low which results in the chlorophyll-a mean case which is a food sources of lemuru fish. Based on Trenberth's theory, (1997), the rise and fall of the ENSO Index of less than six months is not stated in ENSO. From the calculation results during the research of 2007 - 2016 happened three times ENSO phenomenon that is in 2009, 2010 and 2015. At the time of the IOD phenomenon, the IOD (+) phase will result in a decrease in catch while the normal IOD phase and (-) will increase the catch. From the results of this study can also be observed, in the year 2007 - 2011 phenomenon ENSO and IOD have a strong influence on the catch while in the year 2012 - 2016 the influence of the phenomenon of ENSO and IOD has no strong influence caused by the quantity of lemuru fish that have been over exploitation that resulted in the current Bali Strait on Over Fishing status.
