Although orangutans are closely related to humans, very little is known about their ontogenetic development. In particular, there is a lack of systematic research on the maternal behaviors that mediate skill development in early infancy. To address this topic, we conducted a longitudinal study in which a Sumatran orangutan (Pongo abelii) mother-infant dyad was systematically observed across 28 mon
Aim: This population-based study assessed the incidence of rickets in infants up to age of one born in Sweden from 1997 to 2014. We also examined maternal and perinatal factors and co-morbidity. Methods: We used Swedish National Board of Health and Welfare registers and data from Statistics Sweden. The outcome measure was an International Classification of Diseases, Tenth Revision, code for ricket
Objective A low expression of club cell secretory protein (CC16) and high levels of proinflammatory cytokines at preterm birth are associated with airway inflammation and more severe neonatal lung disease. The present study aimed to investigate if low levels of CC16, proinflammatory cytokines and vascular endothelial growth factors (VEGF) in tracheal aspirate early after birth were associated with
BIRDS THAT SPEND the winter in a harsh and cold climate face a suite of challenges that require optimization of energy expenditure and energy intake. Some birds roost communally, which can increase energy savings during cold winter nights. However, this behaviour is almost completely absent in chickadees, tits, and titmice (Paridae) as there are very few accounts in the literature of parids roosti
The study examines very Young children with the aim of identifying precursors of developmental problems during, the first 7 months of age. Information front screening, and observations in the birth clinic, in the first level of health care. and from parents was collected on five different occasions. The information that Was included concerning the child and family was defined as either optimal or
For 10 consecutive winters, measurements were carried out in Lake Vendyurskoe, Karelia, Russia. The aim of these measurements was to investigate some of the physical processes in this small shallow lake during its ice-covered period. Detailed measurements of ice thickness and condition, snow thickness, water temperature, salt content, and currents were developed into a database. Within this databa
The partitioning of P among major chemical forms was studied in 110 non-fertilized, semi-natural grassland soils of southeastern Sweden, comprising a wide range of soil acidity and other chemical properties. The P fractions bound to Ca and Fe were closely related to soil acidity, expressed as pH-KCl, especially when calculated as % of the total pool of mineral P. The relationship was inversely lin
Müller cells are essential in creating and maintaining intricate neuroretinal architecture. The functions of this important glial cell are not limited to mere support of the retinal neurons, but also include interaction in synaptic transmission and activation in response to retinal insult. In this study, we have examined Müller cell morphology and degree of activation in embryonic full-thickness r
The post-war years were a time of expansion in Swedish publishing. The economy was growing, people became better educated, the rise of a large middle-class meant new costumers, new publishing and sales strategies added to the increasing market, and overall there was higher sales, more titles published and more people reading. Despite the success story there has been hardly any research done on the
Background It might be that early intestinal colonization by bacteria in westernized infants fails to give rise to sufficient immune stimulation to support maturation of regulatory immune mechanisms. Objective The purpose of the present study was to characterize the very early infantile microbiota by using a culture-independent approach and to relate the colonization pattern to development of at
The fatigue crack propagation rate is influenced by various mechanisms at the very vicinity of the crack tip, e.g., local plasticity and/or creep, microcracking, crack branching, and crack closure induced by plasticity and roughness. To study these mechanisms and their influence on crack propagation rate during different loadings, in situ scanning electron microscope studies have been performed. T
Heterogeneous rare-gas clusters produced by a coexpansion of an argon/xenon mixture have been studied using synchrotron-radiation-based photoelectron spectroscopy. Both valence and Xe 4d(5/2) core-level photoelectron spectra were recorded for three different concentrations of the primary argon/xenon mixture and, for those mixtures, spectra were recorded at several different stagnation conditions.
A landscape genetics approach was applied to common goby (Pomatoschistus microps) sampled from three estuaries (six sites) of the Portuguese coast. Individuals of each site were genotyped for eight microsatellite loci and levels of genetic diversity and differentiation were correlated to present-day estuarine characteristics and historical events. A general ecological state for each sampling site
In the history of English language research on computerised corpora, the year 1977 marks an important event with the birth of ICAME - the International Computer Archive of Modern and Medieval English - which set off international co-operation on a large scale. The use of computer corpora, from being a fringe activity, has become a mainstream methodology. Yet there was corpus life also before ICAME
During the spring of 2003 ninety-five water bodies in southeastern Estonia were surveyed for chrysophytes. The sampling was carried out as the ice broke up, when, within two weeks, the water temperature rose from 3 degrees C to 13 degrees C. Large lakes to small pools of different water chemistry were investigated. The plankton collected was studied alive within a few hours after sampling. Prepara
Neutron deficient nuclei close to Sn-100 have been studied using the NORDBALL Ge-detector array together with ancillary particle detectors. Evaporation residues from the compound nucleus Te-108 were identified with charged particle and neutron detectors. In this paper a considerable extension of the level scheme of the nucleus Cd-102 is presented. The strongest cascade of the new level scheme reve
Popular Abstract in Swedish Arktiska ekosystem utgör en viktig del av det globala terrestra utbytet av växthusgaser och energi med atmosfären. I ett klimat som förändras, särskilt uttalat i Arktisk, bör tänkbara framtidsprognoser av växthusgasutbytet från dessa områden övervägas noga när framtida klimat modelleras. En förutsättning för detta är detaljerade studier av nyckelprocesser som påverkar vArctic ecosystems represent an important component in the global terrestrial exchange of greenhouse gases and energy with the atmosphere. In the changing climate, which is most pronounced in the Arctic, the possible scenarios of greenhouse gas exchange response should be seriously considered in predictive climate modelling efforts. As a prerequisite for this, detailed studies of key processes affe
The aim of this thesis is to study four important determinants for the prognosis of prosthodontic treatment, namely the patients expectations, personality traits, and satisfaction with treatment. The fourth aim is to relate the technical quality of the treatment to the patient's opinion about it. A specially designed questionnaire to explore expectations of treatment was sent to 489 patients await
This study was designed to investigate the motives patients give for attempting suicide and the associations between these motives and diagnosis, various psychiatric features, suicidal intent and socio-demographic characteristics. The Motives for Parasuicide Questionnaire (MPQ), comprising 14 suggested motives, was presented to 53 patients at a psychiatric ward that specialized in suicide attempte
