Effect of different lignocellulosic wastes on Hericium americanum yield and nutritional characteristics.

Abstract: The aim of this study was to investigate the possibility of using cottonseed hulls (CSH) and olive press cake (OPC) as new supplement materials for substrate preparation in Hericium americanum cultivation. Some chemical properties of the substrates prepared by mixtures of oak sawdust (OS) with wheat bran (WB), CSH and OPC in different ratios were determined. In addition, the effect of mixtures of OS:CSH and OS:OPC on spawn run time, yield and biological efficiency (BE), average mushroom weight and nutrition content of the fruiting body were compared with the control substrate (8OS:2WB).; Results: The yield, BE and average mushroom weight of substrates containing CSH and OPC were higher than the control substrate and increased with an increase in the rate of CSH and OPC in the mixtures. Hericium americanum showed (on a dry weight basis) 8.5-23.7% protein, 9.9-21.2 g kg-1 P, 26.6-35.8 g kg-1 K, 0.63 - 1.33 g kg-1 Mg, 0.19 - 0.23 g kg-1 Ca, 1.34-1.78 g kg-1 Na, 49.5-72.2 mg kg-1 Fe, 6.22-10.11 mg kg-1 Mn, 32.8-82.8 mg kg-1 Zn and 8.6-11.2 mg kg-1 Cu on different growing substrates. The nutritional value of mushrooms was greatly affected by the growing media.; Conclusion: The results revealed that CSH and OPC could be used as new supplement materials for substrate preparation in H. americanum cultivation. © 2016 Society of Chemical Industry.; © 2016 Society of Chemical Industry.

The relaTionship beTween prospecTive Teachers' sTraTegies for coping wiTh sTress and Their percepTions of sTudenT conTrol

Abstract: The relationship between prospective teachers’ preferred strategies for coping with stress and their perceptions of student control were examined by use of a relational survey model to determine the relations between these concepts. The study group consisted of 267 prospective teachers at the Faculty of Education in Kirsehir, Turkey. Data were collected from senior class faculty students using 2 scales: The Ways of Coping Scale (WCS) originally developed by Lazarus and Folkman (1984) and adapted into Turkish by Sahin and Durak (1994) and the Scale of Locus of Student Control developed by Miller et al. (1988) and adapted into Turkish by Abaci (1996). Pearson moment correlation was used to analyze the data. Findings showed that there was a noticeable meaningful statistical relation between variables. Findings are discussed based on the literature.

Genetic Diversity and Structure at Different Spatial Scales in the Processionary Moths

Abstract: This chapter presents the evolutionary history of Thaumetopoea species associated with pines, at different temporal and spatial scales. It corresponds to recent discoveries and ongoing works using sequencing technologies and population genetics. Most of the subchapters focus on the winter pine processionary moths T. pityocampa/T. wilkinsoni including a population with a shifted life cycle. Results concerning the summer pine processionary moth T. pinivora and the evolution of the whole genus are also presented. This chapter gives insights about the effects of Quaternary climate changes in different regions, and allow to study the contemporary changes due to the present climate warming.

A Diagnostic Comparison of Turkish and Korean Students’ Mathematics Performances on the TIMSS 2011 Assessment

Abstract: The purpose of the present study was to analyze an international large-scale data set using a cognitive assessment approach. Although some researchers question the usefulness of international large-scale assessments (e.g., TIMSS), participating countries have continued to use the results from these large-scale assessments to improve their curricula and teaching methods. Despite the common reporting practice—single-score—in these large scale assessments gives useful insights about students’ overall performances, they still lack diagnostic information. Cognitive diagnosis models (CDMs) were developed to provide more feedback on students’ cognitive strengths and weaknesses. This study retrofitted the TIMSS 2011 eighth grade mathematics assessment by applying a specific CDM called the DINA (the deterministic, inputs, noisy, “and” gate) model to data from South Korea and Turkey. Results of the DINA model were used to make a detailed comparison between students of these two countries.

Fractional maximal function and its commutators on Orlicz spaces

Abstract: In this paper, we find necessary and sufficient conditions for the boundedness of fractional maximal operator $$M_{\alpha }$$ on Orlicz spaces. As an application of this results we consider the boundedness of fractional maximal commutator $$M_{b,\alpha }$$ and nonlinear commutator of fractional maximal operator $$[b,M_{\alpha }]$$ on Orlicz spaces, when b belongs to the Lipschitz space, by which some new characterizations of the Lipschitz spaces are given.
