Full Text Available In contemporary globalised cities it has become increasingly important, for those of us who live in monotonous so-called cloned-environments, to find a sense of place we can identify with. When ties between inhabitants and places are disrupted, people are estranged from their neighbourhoods. As a result, not only people’s relations with places are harmed, but also their social relations are affected, leading to isolation, alienation and socio-economic disruption. The causes of these relations are analysed through the concept of place attachment. Since the 1970s, research on place attachment has grown considerably. These studies are mostly focused on sense awareness and affectiveness, with the physical attributes of places accorded lesser attention (Lewicka, 2011. In a similar vein Christopher Alexander (et al, 1977 has asserted that, when studying place attachment, influences associated with human feelings only comprise ten percent of total influences, while the rest derive from the physical characteristics of places. And yet these are the least examined objects of study. In this context, the aim of this paper is to examine more closely the spatial qualities of places in the formation of place attachment. For the study, a long-established neighbourhood of Istanbul, Kuzguncuk, has been chosen to analyse the works of Christopher Alexander, Kevin Lynch, Jane Jacobs and John Montgomery. As a result, a matrix showing the spatial/physical qualities which have allowed the inhabitants of Kuzguncuk to develop a stronger attachment to their neighbourhood will be presented.

Denitrification, the reduction of oxidized forms of inorganic N to N2O and N2 is an important pathway of gaseous nitrogen losses. Measuring denitrification, especially the reduction of N2O to N2, expressed in the product ratio (N2O/(N2O + N2)), is rather difficult and hence rarely performed under field conditions. But using the 15N gas-flux method allows determining N transformation processes in their natural environment. In order to develop effective climate mitigation strategies understanding the N2O source is essential. We used the 15N gas-flux method to determine N2O and N2 emissions following grassland renewal and conversion techniques. Therefore we selected three different treatments: control (C), mechanical grassland renovation (GR) (autumn 2013) and grassland conversion to maize (GM) (spring 2014) from field plot trials on two different sites (Histic Gleysoil and Plaggic Anthrosol) near Oldenburg, Lower Saxony, Germany. We applied 15N labeled KNO3- (60 atom. % 15N) at a rate equivalent to common farming practices (150 kg N*ha-1) using needle injection of fertilizer solution in three different depths (10 cm, 15 cm, 20 cm) for homogeneous soil labeling up to 30 cm in microplots. During the first 10 days after application (May 2014) gas flux measurements from closed chambers were performed every second day and then weekly following a period of 8 weeks. Gas samples were analyzed for δ15N of N2 and N2O by IRMS according to Lewicka-Szczebak et al. (2013). Concentration and 15N enrichment of NO3- in soil water was determined on weekly samples using the SPIN-MAS technique (Stange et al. 2007). Fluxes of N2 and N2O evolved from the 15N labeled soil nitrogen pool were calculated using the equations of Spott et al. (2006). Peak events of N2 and N2O emissions occurred during the first 10 days of measurement, showing differences in soil types, as well as treatment variations. N2 fluxes up to 178 g*ha-1*day-1 and N2O fluxes up to 280 g*ha-1*day-1 were measured on the
Universities had similar historical traces, but currently, they are developed in three different independent countries with different cultural and historical politics which might have an influence on the perception of the place’s past (Lewicka, 2011

Children's and adolescents' injuries are a serious medical problem, as they lead to substantial medical and socio-economic effects. Aim of the paper. The aim of the conducted research was to analyze incidence and causes of hospitalizing children between birth and 18 years of age on the grounds of injuries. Material and methods. Medical histories of 2 832 children between birth and 18 years of age treated for injuries in 2006-2010 in Wladyslaw Bieganski Regional Specialist Hospital in Grudziadz were analyzed. Results. Correlations between treatment method and subsequent years of research (p<0,05, between children's age group and type of injury, and between type of injury and season of the year and hospitalization time, were shown to be statistically significant. No correlation was found in the studied population between subsequent years of research and injury types or residence of the injured. Conclusions. 1. The most frequent causes for placing children in the hospital were cranioencephalic injuries, injuries to the osteoarticular system, and burns. 2. The children's age determined the type of injury inflicted. Children in the youngest age group were most frequently hospitalized for burns, children in the age of 3-6 years for foreign bodies, and in the group of 7-18 years of age for injuries to the chest and to the osteoarticular system. 3. Boys were more frequently injured in a manner requiring hospital treatment than girls were. 4. A decisive majority of injured children required only conservative treatment and a stay in the hospital for no more than 3 days. 5. A constant tendency of higher occurence of injuries in children during spring and summer, was observed. Keywords: children, injuries

. Investigations were carried out over a study period of one year following grassland renewal and grassland conversion to maize cropping on two different soil sites (Plaggic Anthrosol and Histic Gleysol) near Oldenburg, Lower Saxony Germany. Our observations indicate heterotrophic bacterial denitrification and/or nitrifier denitrification as the main source of N2O production, with a significant contribution of N2O reduction to N2 rather than nitrification (i.e. hydroxylamine oxidation) and fungal denitrification throughout the entire study period. A tendency to a higher contribution of N2O reduction to N2 was observed for the often water-saturated Histic Gleysol, while lower N2O reduction was found for the Plaggic Anthrosol. For two samples, we attempt to validate our results from the isotopocule mapping approach with a parallel 15N labelling study at the field scale (Buchen et al., 2016), as conditions of soil moisture, nitrate availability and N2O flux were similar.
