This article explores how the processes of writing and writers emerge and transform in two examples of Swedish early childhood educational writing practices. Students' writing is a multifaceted activity involving a myriad of interconnected elements;however, to make sense of what is going on, more knowledge is needed about the connectivity, the movement and the unpredictability inherent in these activities. Taking a posthuman and nomadic perspective, the article studies how text and writer are co-constituted through the interrelations between human elements and non-human elements. The article concludes that conceptualizing writing as nomadic provides a way to view young children's educational writing as sites of experimentation, thus guiding the pedagogical attention to the productive potential of the writing situation.

The current study aimed to investigate the association between dietary amino acid patterns and incidence of hypertension, using principal components factor analyses. This study was conducted within the framework of Tehran Lipid and Glucose Study on 4288 adults, who were free of hypertension at baseline (2008-2011) and were followed for three years (2011-2014). Principal component factor analyses were conducted based on eight amino acid groups and three amino acid patterns were extracted. The first pattern was characterized by branched chain, aromatic, and alcoholic amino acids, and proline. Acidic amino acids and proline were highly loaded in the second pattern and the third was characterized by sulphuric and small amino acids. Adjusted odds ratio of the highest quartile of the first pattern was 1.83 (95% CI: 1.21-2.77, P for trend = 0.002) compared to the lowest one. The first pattern had high positive correlation with dietary intakes of animal protein and dairy, but was negatively correlated with plant protein, fruit, and vegetable. There was no significant association for the second and third patterns. Findings indicate that the dietary amino acid pattern, rich in branched chain, aromatic, and alcoholic amino acids, and proline could increase the risk of hypertension.

In this paper, a new data-driven method for short-range forecasting of spatio-temporal systems is proposed. It uses NCEP data as raw data to construct forecasting model. The global model consists of several local models. Each local model is constructed in three steps. In the first step, a local dataset is constructed based on NCEP raw data. This dataset is a very high-dimensional data with huge number of redundant and irrelevant features. In the second step, a feature selection method named GRASP is applied on the local dataset and produces a new local dataset whose features are reduced significantly. In the third step, a regression ensemble method called Bagging is used to construct a local model. Both GRASP and Bagging methods are scalable modules with respect to the computational power needed. The proposed method makes it possible to control the trade-off between speed and precision. In addition to the scalability, the proposed method, in some points produces forecasts more precise than the GFS system.

Free oxygen radicals are claimed to be of major importance in tissue damage in the newborn. Ethane (E) and pentane (P) are specific products of free oxygen radical mediated lipid peroxidation (Lipids 12: 109-114, 1977). We have quantified these alkanes in expired air from 12 infants, gestation 25 to 31 weeks. All received mechanical ventilation and supplemental oxygen for treatment of RDS. After wash-out with hydrocarbon scrubbed air/O2the expired air was collected into a bag, trapped Into Porasil-C adsorbent, and analyzed with Internal standard by *** the first three neonatal days E production ranged from 0 to 133 pmol/kg/min and P from 0 to 39.5 pmol/kg/ min. E and P did not correlate well with the severity of the respiratory failure or with the requirement of supplemental oxygen during the time of gas analysis. However, infants who eventually developed BPD (n=2) or died (n=2), tended to produce more E (63.4 pmol/kg/min, range 0-133), and P (29.1 pmol/kg/min, range 12.9-39.5), compared to babies with a favourable prognosis: 22.9 pmol/kg/min (0-55), and 11.3 pmol/kg/min (0-22), respectively. We propose that analysis of E and P Is instrumental in studying the role of free oxygen radicals in diseases of the newborn.
