The aim of this study is to investigate the stabilization of tannery sludge compost mixed with cattle manure at the different ratios by employing an epigeic earthworm Eisenia foetida and bioaccumulation of Cr in tannery sludge by earthworms. Organic cattle manure (M) and sludge compost (S) were mixed in certain proportions, moistened and Eisenia foetida worms were added. Mixing ratios were as follows: 100% M (M100S0), 70% M + 30% S (M70S30), 50% M + 50% S (M50S50) and 30% M + 70% S (M30S70). The experiment was carried out at a constant temperature of 24 °C and in a dark environment according to a randomized plot design with three replicates. The experiment ended after 120 days and the following parameters were evaluated in vermicomposts: pH, electrical conductivity (EC), total nitrogen (TN), total organic carbon (TOC), C:N ratio, and total macro and micro elements. In addition, it was determined total Cr, Cr (VI) in vermicomposts and total Cr in E. foetida body. The results for TOC, C:N ratio and total Cr showed decreases in their values at the end of the vermicomposting process, whereas values for pH, EC, TON, Ca, and Mg increase, indicating that the vermicomposting reached the maturity level. All values of Cr (VI) of vermicomposts were below the detectable level. During the vermicomposting process, the reduction rates of the total Cr amounts were 96% (M70S30), 96% (M50S50) and 30% (M30S70), respectively. While the highest total Cr amount in the earthworm body was determined in M30S70 treatment, the amount of this element in the earthworm body decreased due to the decreasing doses of tannery sludge compost. These results show that E. foetida can bioacumulate the chromium in tannery sludge compost. As a result, it was determined that vermicomposting can be an alternate technology for the recycling and environmentally safe disposal/management of tannery sludge compost using an epigeic earthworm E. foetida.

Membrane bioreactors (MBRs) are commonly used in municipal and industrial wastewater treatment. However, membrane fouling problem limits the performance of MBRs. The objective of this study was to determine the impact of vibration on membrane fouling. Long-term filtration experiments were conducted to compare treatment and filtration performance of vibrated (magnetically induced) and non-vibrated modules in an MBR treating synthetic municipal wastewater. Results showed that vibration did not have any remarkable effect on treatment performance. However, filtration performance and thus, membrane fouling were significantly affected by the vibration. Magnetically induced vibration system achieved better filtration performance than the non-vibrated module. Cake layer formation found in the magnetically induced vibrating system resulted in low potential for pore clogging. The results suggest that magnetically induced vibration is a promising alternative for reducing membrane fouling problem in MBR systems. [ABSTRACT FROM AUTHOR]

Establishment of technology assisted environments suitable for new teaching programs has become more of an issue each passing day. From this aspect, Teaching Technologies and Material Design (TTMD) course comes first as applied courses modeling the knowledge generation in pre-service teacher education. One of the teaching activities within the scope of this course is the activities of pre-service teachers for short film preparation and application. Ministry of National Education (MEB) encourages the short film designs through Education Informatics Network (EBA). Integration of technological and pedagogical knowledge that pre-service teachers have within the frame of content knowledge to be taught has been aimed with this kind of activities. This study includes the examination of technological and pedagogical properties of scripts of early childhood pre-service teachers in short film designs. In this research that has been performed with pre-service teachers in KTÜ (Karadeniz Technical University) Fatih Faculty of Education, Early Childhood Education Department, short film production towards the suitable ones for the zones of development and objectives within the MEB Early Childhood Education Program (2013) was asked from groups of four. 5 films selected by criterion sampling method from educational short films prepared, were examined in terms of technical skills, suitability for pedagogical learning objectives and child development, varieties of representation, and knowledge of learner (pre-conceptions and learning disability characteristics). Results refer to that short film contents are suitable for zones of development with pedagogical learning objectives indicators in this type of scripting beside the film preparation skills in terms of technical skills, It has been seen that even if a variety of representation in terms of early childhood education was provided, there are not enough applications characterizing the pre-conceptions in short film contents.

The present research was conducted with 518 students enrolled at the 6th, 7th and 8th classes of primary schools. A likert-type scale developed by Tuan, Chin and Shieh (2005) and translzated into Turkish by Yılmaz and Çavaş (2007) was used to examine the motivation levels of students towards science learning. Research findings revealed that gender, academic success and taking private lesson had an effect on students' motivation levels towards science learning. It was found in the study that: the motivation level of female students was higher than male students; academic achievement and taking private course increased the motivation; and laboratory activities, and parents' educational levels did not have an effect on students' motivation.
