Two successful samples of land treatment systems are introduced in the paper. A rapid infiltration system of the area 11.3 hectares with treatment capacity of 10,000 m3/day was constructed in Pingdu city of Shandong province. The removal of COD reached 87.5% while 89.4 for suspended solids and 64.4 % for NH3-N. In fact, the treated water already achieved the criteria of the secondary treatment eve
Global heating is a topic that is debated in every part of the world. The weather has become more extreme. While scientists debate over the reason for those extremes it is no doubt that emission of greenhouse gases are constantly increasing globally. China has in the past years substantially increased their investment in energy to cope with the demands of their booming economy. Much of the increas
För att effektivt utforma reklam samt integrera denna över nationsgränser är det viktigt att ha en god förståelse för vad som skiljer ländernas kulturer åt. Det är dessutom viktigt att kunna hantera dessa skillnader för att nå fram med det tilltänkta budskapet. Med utformning menas på vilket sätt en reklam är presenterad, vilket kan liknas med manuset till en film. Syftet med denna uppsats är att
We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies). A diverse set of process routes will be necessary to produce all intermediates and commercial products. In
Background Mycobacterium tuberculosis (TB) is the deadliest disease that claims millions of deaths globally. Ethiopia is among the countries heavily hit by the disaster. Despite the effective directly observed treatment and TB infection control (TBIC) measures provided by the world health organization (WHO), the rate of new cases increased daily throughout the country. Healthcare workers (HCWs) ar
Cell reprogramming concepts have been classically developed in the fields of developmental and stem cell biology and are currently being explored for regenerative medicine, given its potential to generate desired cell types for replacement therapy. Cell fate can be experimentally reversed or modified by enforced expression of lineage specific transcription factors leading to pluripotency or attain
The main objective of the study was to investigate the thermal performance of five (open and closed) bicycle helmets for convective and evaporative heat transfer using a nine-zone thermal manikin. The shape of the thermal manikin was obtained by averaging the 3D-point coordinates of the head over a sample of 85 head scans of human subjects, obtained through magnetic resonance imaging (MRI) and 3D-
INTRODUCTION: Whether melancholia is a distinct syndrome has long been debated. One aspect of a valid syndrome is whether it allows for determination of a prognosis. The aim of this study is to investigate the course of melancholic depression versus non-melancholic depression with a focus on: (i) time to and probability of recovery from the first depressive episode, (ii) time to and risk of the fi
Relationer med nära vuxna är viktiga för barns utveckling. Forskning om känslomässig trygghet, så kallad ”anknytning”, mellan barn och förälder har visat att hur föräldrar bemöter barnets behov av tröst och närhet inverkar på barnets sätt att hantera känslomässig stress och navigera sociala relationer. Även andra omsorgspersoner i ett barns vardagsliv kan bli anknytningsfigurer för barnet, såsom pCurrent child developmental research encourages a more systemic understanding of attachment-related relationship-building. As many young children spend a substantial part of their daily life in professional childcare, e.g., “preschool”, interactions with teachers at preschool are of particular interest in this respect. In bridging the developmentally important contexts of home and preschool for th
Small routines and ingrained cultural reflexes as well as micro-rituals form an often unnoticed or ignored flow in everyday life. They acquire their power by being taken for granted and embodied. In situations of conflict, crisis or change, they may suddenly be noticed and become problematic. This chapter looks at how moves, affect, sensations and stuff interact in the making and unmaking of routi
This edited work draws on a range of contributed expertise to trace the fortune of an Aristotelian thesis over different periods in the history of philosophy. It presents eight cases of direct or indirect challenges to the Aristotelian passive account of human cognition, taking the reader from late antiquity to the 20th century. Chapters analyse the (often indirect) effect of Aristotle’s account o
In mammals, IgA is the antibody class that is produced in largest quantities. The main producers are plasma cells located in the lamina propria at mucosal surfaces that secrete it as dimers covalently linked to the J chain. Polymeric immunoglobulin receptors (pIgRs) expressed on epithelial cells bind to dimeric IgA molecules and mediate basolateral to apical transcytosis, before IgA is released in
Superantigens are immune-stimulatory toxins produced by Staphylococcus aureus, which are able to interact with host immune receptors to induce a massive release of cytokines, causing toxic shock syndrome and possibly death. In this article, we present the x-ray structure of staphylococcal enterotoxin B (SEB) in complex with its receptors, the TCR and MHC class II, forming a ternary complex. The st
