This study aimed to determine the opinions of prospective science teachers about qualifications that a teaching material should have. Qualitative research was conducted with 31 participants from 15 different universities. Data were collected through semi-structured interview form. The form applied face-to-face after training organized increase pre-service teacher's knowledge and skills on integ...

Changing climate is predicted to impact all depths of the global oceans, yet projections of range shifts in marine faunal distributions in response to changing climate seldom evaluate potential shifts in depth distribution. Marine ectotherms' thermal tolerance is limited by their ability to maintain aerobic metabolism (oxygen- and capacity-limited tolerance), and is functionally associated with...

The enteric nervous system (ENS) is a complex network of neurons in the gut, regulating many local, vital functions of the gastro-intestinal tract. The ENS is also part of the bidirectional gut-brain axis. The murine immorto fetal enteric neuronal (IM-FEN) cell line was chosen as a model to study enteric neurons. This cell line can be differentiated into cells with a neuronal phenotype, althoug...

Okul öncesi fen eğitiminde temalı bilgi veren resimli çocuk kitapları, bilimsel bilgilerin kazandırılmasında ve süreç becerilerinin geliştirilmesinde oldukça önemlidir. Ulusal uluslararası alan yazında yapılmış olan araştırmalar okul öğretmenlerinin fene karşı ön yargılı düşük öz-yeterlik inancına sahip olduklarını, kavram bilgilerinin yeterli düzeyde olmadığını göstermektedir. Bu noktada dönem...

Rates of methane production in Minnesota peats were studied. Surface (10- to 25-cm) peats produced an average of 228 nmol of CH(4) per g (dry weight) per h at 25 degrees C and ambient pH. Methanogenesis rates generally decreased with depth in ombrotrophic peats, but on occasion were observed to rise within deeper layers of certain fen peats. Methane production was temperature dependent, increas...

The Canadian boreal forest consists of a mosaic of landscapes of varying soil drainage and forest age driven by wildfire. The hydrological consequences are complicated by plant responses to soil moisture and forest age, both potentially influencing evapotranspiration. Evapotranspiration was measured using the energy balance residual technique in 2006 and 2007 at forested upland and fen sites th...

The composition of a peatland plant community has considerable effect on a range of ecosystem functions. Peatland plant community structure is predicted to change under future climate change, making the quantification of the direction and magnitude of this change a research priority. We subjected intact, replicated vegetated poor fen peat monoliths to elevated temperatures, increased atmospheri...

The aim of the present study was to describe a large cohort of fenfluramine-associated pulmonary arterial hypertension (fen-PAH) and its possible prognostic markers. The records of all patients with a diagnosis of fen-PAH evaluated at the present authors' centre from 1986-2004 were retrospectively studied. Baseline clinical and haemodynamic data were collected, as well as survival times. The me...
