The current research was conducted to determine the comparison of hatchability and some egg quality characteristics in spotted and unspotted partridge (Alectoris chukar) eggs. The research was carried out on 51 male and 102 female chukar partridges (Alectoris chukar) aged 50 wk, which were raised at the Research and Application Farm of the Faculty of Veterinary Medicine of Selcuk University. In total, 244 spotted and 261 unspotted eggs were used in the research. The hatching eggs were stored at 75% RH and 13°C for 14 d. Thirty spotted and 30 unspotted eggs laid on the same day were used for the evaluation of egg quality characteristics. Egg weight, chick weight, egg weight loss during the hatching period, shape index, hatchability, and some egg quality characteristics were evaluated at the end of the research. Spotted eggs exhibited a higher fertility and hatchability, as well as a lower percentage egg weight loss and embryonic mortality when compared with unspotted eggs. No significant differences were observed between spotted and unspotted eggs for egg weight, chick weight, shape index, specific gravity, albumen height, Haugh unit, yolk color green-red chromaticity (a*), albumen pH, and yolk pH. Spotted eggs had higher eggshell color a*, eggshell color blue-yellow chromaticity (b*), and eggshell strength, as well as a lower eggshell color light-dark chromaticity (L*), yolk color L*, and yolk color b* scores when compared with unspotted eggs. It was demonstrated that spots on the eggshells of chukar partridges (Alectoris chukar) improved their hatchability by affecting various quality characteristics of their eggs. It was concluded that spotted eggs are more suitable for hatching. © 2014 Poultry Science Association Inc. Source

Modified atmosphere packaging (MAP) is a shelf-life enhancing method which is growing rapidly on an international scale. The correct gas mixture and film in MAP can maintain high quality with extended shelf life. However, the initial gas composition in the package headspace often changes as a result of the activity of the respiring product, the nature of the package, or the environmental conditions. In the new MAP era, it is necessary to show that MAP does not only deal with gas mixtures and films. The new thought is to incorporate new packaging concepts such as active and intelligent packaging technologies with MAP in order to monitor gas change, storage temperature, quality of packaged product, and maintain the initial gas level during the whole storage time. Indicators or sensors in the form of a package label or printed on packaging films can monitor changes in the gas composition, storage temperature and quality of the product (smart packaging concept). Sensors adapted in the MA package could detect gas levels (smart packaging concept) and also the sensor could release gas to compensate for gas losses in the package (active packaging concept). Thus, the initial gas mixture could be maintained in the MA applied package during the storage time. In addition, gas indicators such as oxygen and carbon dioxide indicators could be used to monitor maturity stage of fruits based on the gas change in the package. Another application of these indicators is to determine package leakage which not only causes change in internal atmosphere but also microbial contamination from the environment. The use of intelligent indicators (time-temperature indicators, gas and freshness indicators) and active packaging technologies (ethylene and moisture absorbers) in conjunction with MAP is discussed in the paper. MAP combined with active and intelligent packaging concepts will provide a means of monitoring the quality and safety of the respiring products. Source

Dehydrofreezing which is the drying of foods to intermediate moisture content and subsequent freezing has the advantages of lowering the transportation costs due to reduced weight and improved texture. The available empirical equations for freezing time prediction and the experimental data on thermo-physical properties are for fresh produce. Some of these empirical equations were used to predict the freezing times of papaya puree infinite cylinders with initial moisture contents ∼52% to ∼91%. The accuracies of these methods to predict the freezing times for final center temperatures of-10 °C and-18 °C were discussed. The most accurate methods for fresh and partially dries papaya puree were suggested. © 2010 Elsevier B.V. All rights reserved. Source

The purpose of this study is to determine levels of technological proficiency among university students to see if they should be characterized as "digital natives." For this purpose, rather than using types and frequency of technology use to characterize a digital native, the Digital Native Assessment Scale (DNAS) developed by Teo (2013) was employed. This scale has an established reliability and validity measure. It measures several factors (e.g., grew up with technology, comfortable with multi-tasking, reliant on graphics for communication, thrive on instant gratifications and rewards, etc.) relating to accepted characteristics of a digital native. The participants in the study were 560 university students, 278 of whom were from Turkey and 282 from Kyrgyzstan. The findings indicate that these university students actively used computers and the Internet. The statistical results show that digital natives can be characterized by including their academic year (Freshman, Sophomore, etc.), national culture, and experiences with technology (computers, tablet PCs, and the Internet). The results also indicate that there are no significant differences in the participants' perceptions of themselves as digital natives due to their gender or academic disciplines. © 2016 Elsevier Ltd.

This study investigates the causality relationship between energy consumption and economic growth in 17 transition countries, which are Albania, Armenia, Belarus, Bulgaria, Czech Republic, Estonia, Hungary, Kazakhstan, Kyrgyz Republic, Latvia, Moldova, Poland, Romania, Russian Federation, Slovenia, Ukraine, and Georgia. Empirical findings indicate that there is unidirectional causality from economic growth to energy consumption in the long run. The results support for conservation hypothesis suggests that energy conservation policies have no effect on economic growth. They can simultaneously achieve policy goals concerning growth and energy. © 2016 Taylor & Francis Group, LLC. Source
