In this study, a 128 kb ultra low voltage (ULV) SRAM, based on a 7T bitcell with one bitline, is presented. Overall energy efficiency is enhanced by optimizations on all abstraction levels, i.e., from bitcell to macro integration. Degraded performance and reliability due to ULV operation is recovered by selectively overdriving the bitline and wordline with a new single-cycle charge-pump. A dedicat
Lignocellulosic bioethanol from renewable feedstocks using Saccharomyces cerevisiae is a promising alternative tofossil fuels owing to environmental challenges. S. cerevisiae is frequently challenged by bacterial contamination anda combination of lignocellulosic inhibitors formed during the pre-treatment, in terms of growth, ethanol yield andproductivity. We investigated the phenotypic robustness
An on-chip, low power, and area efficient charge-pump (CP) that generates a multiple of the supply voltage (VDD) in a single clock cycle is presented. The proposed CP utilizes parallel cross-connected CP units, which are implemented using MIM (metal-insulator-metal) capacitors. In the target application, i.e., a sub-threshold SRAM, the capacitors are accommodated on top of the memory banks to remo
The overall aim was to investigate informal caregivers providing care for older persons with dementia (≥ 65 years of age) in eight European countries. Focus was on their experiences of formal care, access to support and factors that were associated with caregivers’ psychological well-being and burden. Caregivers’ experiences of formal care were investigated in a qualitative study with four focus gThe overall aim was to investigate informal caregivers providing care for older persons with dementia (≥ 65 years of age) in eight European countries.

When a parent is suspected for child abuse, the court in Sweden appoints a lawyer who can decide about the child’s participation in CH without parent’s knowledge or consent. The lawyer brings the child to CH. A familiar person, for example a teacher, accompanies the child. In the study children and their parents are interviewed about their experience and understanding of CH.
Background and aims: Ca2+-induced exocytosis is essential for insulin to be secreted from beta-cells, and in islets from type-2 diabetic (T2D) donors the expression of several genes coding for exocytotic proteins is reduced. Largely this phenomenon cannot be explained by polymorphism; rather it is likely due to epigenetic factors like microRNAs (miRNAs). Indeed, previous studies have identified a
The review presented by Bellomo et al. [1] addresses the modelling approaches employed to represent human behaviour in evacuation in a comprehensive manner. The authors discuss crowd evacuation modelling in light of crisis management, a relevant and current topic given the recent escalation of terrorist threats all over the world. The need for designing buildings for rapid evacuation using crowd e
En allt större del av Sveriges befolkning och företag finns i städer och storstadsområden där löner och produktivitet ofta är högre än på landsbygden. I den här rapporten undersöker vi Sveriges ekonomiska geografi och tillväxt i svenska kommuner. Vi diskuterar också ett urval av politiska åtgärder som används för att försöka skapa regional tillväxt: infrastruktursatsningar, utbildningssatsningar,
World electricity consumption is drastically increasing. One of the most common ways of producing electricity is to use the chemical energy of fossil fuels. This can be done in thermal power plants in which the chemical energy of fossil fuels such as natural gas is converted to mechanical energy and finally to electricity. Extracting the chemical energy of fuels is done through combustion of the f
This ethnographic study explores how Singaporean middle-class women who have opted out of the traditional labour market to support their children actively redefine their roles and responsibilities. How are investments of time, energy, emotional and economic resources in children’s education explained, and what bearing do they have on norms of motherhood? While involved or intensive parenting style
PalCom is a pervasive middleware that enables users to combine the services on devices into useful configurations. Interconnected PalCom devices can discover, and keep track of, the existence of each other by exchanging periodic heartbeats within local networks, and once-sent device appearance/disappearance notifications across interconnected networks. This approach has the advantage of eliminatin
AIM: Physical performance in chronic kidney disease affects morbidity and mortality. The aim was to find out which measures of physical performance are important in CKD and if there are associations with declining measured GFR.METHODS: Endurance was assessed by 6-minute walk test (6-MWT) and stair climbing, muscular endurance by 30-seconds sit to stand, heel rises and toe lifts, strength by quadri
This article draws attention to reported experiences of boredom in knowledge work. Drawing on extensive qualitative data gathered at two management consultancy firms, we analyze these experiences as a particular interaction with identity regulation and work experiences. We conceptualize the reports of the bored self as a combination of unfilled aspirations and the sense of stagnation, leading to a
