Opis:
The objective of the presented research was to test whether working memory, measured using the Spin the Pots task, is an important factor in passive vocabulary development in 2- and 3-year-old children. Two longitudinal studies were conducted. In the first, 135 children participated in the first study. At 18 months their responding to joint attention was measured, and then at 24 months their working memory and passive vocabulary was tested. It was demonstrated that responding to joint attention predicts the level of development of working memory, which in turn influences the extent of the passive vocabulary. In the second study, 113 children participated - at 30 months their working memory was measured, and at 24 months and then 36 months their passive vocabulary was tested. It was observed that at the age of 3 working memory is still a significant predictor of passive vocabulary. The usefulness of the Spin the Pots task for measuring the working memory of young children was shown and discussed in conclusions.

Opis:
In the present work, biofuels produced from different raw fatty materials have been proposed as a dominant fuel component in biodiesel-diesel fuel blends. Biofuels were produced from pork lard and rapeseed oil by alkali transesterification using methyl alcohol. Blends of biofuels in volumetric proportions of 60 and 80% of the biocomponent and the remaining part of the conventional fuel were used in a compression ignition engine designed for medium-duty vehicles. The experiments were conducted at two engine rotational speeds (1500 and 3000 rpm, respectively) and a set of load conditions (50, 100, and 200 Nm, respectively). The tests focused on engine efficiency parameters (brake-specific fuel consumption and brake fuel conversion efficiency) as well as exhaust gas emissions (hydrocarbons, carbon monoxide, and carbon dioxide were determined). The obtained results indicate that blends containing biocomponents produced from pork lard were characterized by superior fuel consumption and efficiency results, compared to blends containing biocomponents produced from rapeseed oil. In terms of exhaust emissions, biocomponents produced from pork lard were also characterized by lower emission of all of the examined components compared to rapeseed methyl ester-diesel blends. This study proposes that fuel components obtained from custom (animal) raw-fatty material can be an effective substitute for commonly used rapeseed oil methyl esters.

Opis:
The development of self-regulation in early childhood is related to development of emotional regulation and attention, in particular executive attention (Feldman, 2009; Posner & Rothbart, 1998). As the ability to self-regulate is crucial in life (Casey et al., 2011), it is important to reveal early predictors of self-regulation. The aim of the paper is to present the results of longitudinal studies on the relationships between the functioning of attention, regulation of emotion and later self-regulatory abilities. 310 children were assessed at three time points. At 12 months of age emotional regulation in situation of frustration and attention regulation were assessed. At 18 and 24 months behavioral-emotional regulation in the Snack Delay Task was measured. Additionally parents assessed executive attention using The Early Childhood Behavior Questionnaire when children were 26 months old. Structural equation modelling revealed two different paths to development of self-regulatory abilities at 18 months: emotional (reactive system) and emotionalattentional and only one emotional-attentional path at 24 months. The early ability to focus attention and later executive attention functioning revealed to be important predictors of self-regulatory abilities both at 18 and 24 months of age.
