Analytical prediction of ultimate moment and curvature of RC rectangular sections in compression

2013

This paper presents closed form expressions linking the ultimate bearing capacity to the ultimate curvature of rectangular RC sections subjected to axial load and bending moment acting in one of the two symmetry planes of the section. With respect to possible simplified formulations the following effects are also considered: confinement of the concrete, hardening of the longitudinal reinforcement, and presence of reinforcing bars distributed orthogonally to the neutral axis. The formulation is proposed in dimensional terms after a preliminary definition of the geometrical and mechanical parameters governing the structural response of the class of sections considered. The analytical expressi…

Disability and work: fitness for work judgement.

2006

The role of physicians, in particular those dealing with health promotion in the workplace, takes on a specific meaning in relation to the difficulties that disabled people encounter both in order to reach the workplace and to reconcile their working activity with the difficulties that result from their condition. Observing the data concerning employment of disabled persons in Italy, it becomes dramatically evident that among the disabled subjects of working age only 17% are employed. OBJECTIVE: The objective of the occupational health physician is to recognise the impairment, study the disability and, possibly, eliminate or reduce the handicap. Achieving this target is difficult, and there…

Balls into non-uniform bins

2014

Balls-into-bins games for uniform bins are widely used to model randomized load balancing strategies. Recently, balls-into-bins games have been analysed under the assumption that the selection probabilities for bins are not uniformly distributed. These new models are motivated by properties of many peer-to-peer (P2P) networks, which are not able to perfectly balance the load over the bins. While previous evaluations try to find strategies for uniform bins under non-uniform bin selection probabilities, this paper investigates heterogeneous bins, where the "capacities" of the bins might differ significantly. We show that heterogeneous environments can even help to distribute the load more eve…

Is there a general theorem that tells us when we can hope for exponential speedups from quantum algorithms, and when we cannot? In this paper, we make two advances toward such a theorem, in the black-box model where most quantum algorithms operate. First, we show that for any problem that is invariant under permuting inputs and outputs (like the collision or the element distinctness problems), the quantum query complexity is at least the 9 th root of the classical randomized query complexity. This resolves a conjecture of Watrous from 2002. Second, inspired by recent work of O’Donnell et al. and Dinur et al., we conjecture that every bounded low-degree polynomial has a “highly influential” …

Latvijas veselības aprūpes institūciju un personāla gatavība katastrofu pārvaldīšanā

2017

Ievads: Pēdējo desmit gadu laikā pasaulē visu veidu katastrofu skaits ir ievērojami palielinājies, kā arī ievērojami ir pieaudzis cietušo cilvēku skaits. Līdz ar to slimnīcām un ārstiem jābūt gataviem risināt ārkārtas situācijas. Šis pētījums novērtē katastrofu pārvaldības sagatavotības līmeni Latvijas veselības aprūpes iestādēs un ārstu vidū. Materiāli un metodes: Materiāli tika apkopoti laika posmā no 2016. gada oktobra līdz 2017. gada februārim. 21 Latvijas slimnīcu administrācijai vai neatliekamās palīdzības vadītājiem tika dota pielāgota aptauja - Slimnīcas ārkārtas situāciju gatavības kontrollapa (Pasaules Veselības organizācijas Eiropas Reģionālā biroja, 2011), kas ietver četras galv…

Possibilities and challenges in sustained capacity-building in early childhood education and care (ECEC) institutions: ECEC leaders’ perspectives

2020

This paper investigates early childhood education and care (ECEC) institutions’ opportunities to build a learning organization and master future innovations by focusing on core components, implementation drivers, leadership, and collective collaborative systems. The paper is based on results from semi-structured interviews with ten ECEC leaders from three different municipalities in Norway that had taken part in the Being Together (BT) innovation five years earlier. Three areas were identified as crucial for the continuation of ECEC teachers’ capacity building: (1) a strong focus on implementation processes and sustainability; (2) transformational leadership; and (3) developing professional…

Creating teacher capacity in Early Childhood Education and Care institutions implementing an authoritative adult style

2017

The being together intervention intends to raise teacher capacity in Norwegian Early Childhood Education and Care (ECEC) institutions and promote social and emotional development in preschoolers by implementing an authoritative (warm and predictable) adult style in the institution. An authoritative adult balances between building up high quality interactions with children, while at the same time having a predictable structure with clear norms and social expectations in the learning environment. The purpose of this study was to investigate what helped the ECEC institutions to successfully implement the program principles and core components, and what were the challenges. The staff groups of …

Some Critical Remarks on the Suitability of the Concept of the Photosynthetic Unit in Photosynthesis Research and Phytoplankton Ecology

1993

Based on the classical definition of the photosynthetic unit after Emerson and Arnold, new definitions are presented and their consistency subjected to critical reflection. Modern molecular approaches to determine the physiological condition or even the efficiency of the photosynthetic machinery via determination of the magnitude of the photosynthetic unit are discussed against the background of new data on the dynamics of the thylakoid membrane.

Photosynthesis and transpiration of healthy and diseased spruce trees in the course of three vegetation periods

1988

CO2- and H2O-gas exchange of 20- to 25-year-old spruce trees from a plantation in the Hunsruck mountains were investigated over a period of 3 years. All measurements were made as pair comparisons, i.e., in each case the gas exchange of a damaged tree and of a relatively healthy tree in its immediate vicinity was measured simultaneously. A second plantation in the Westerwald mountains consisted of 18-year-old apparently healthy spruce trees. Pair comparison at this location meant comparison of two healthylooking trees. The investigations at both locations included diurnal course measurements of photosynthesis and transpiration, and light saturation curves and CO2-saturation curves of photosy…
