Graphics for the masses: a hardware rasterization architecture for mobile phones

The mobile phone is one of the most widespread devices with rendering capabilities. Those capabilities have been very limited because the resources on such devices are extremely scarce; small amounts of memory, little bandwidth, little chip area dedicated for special purposes, and limited power consumption. The small display resolutions present a further challenge; the angle subtended by a pixel i

Clonal chromosome abnormalities in premalignant lesions of the skin.

Two lesions, actinic keratosis (AK) and squamous cell carcinoma in situ (CIS), are believed to be precursors of squamous cell carcinoma (SCC) of the skin. These lesions can serve as an excellent model system for studying genetic changes associated with the inception of skin SCC. In the present study, five such lesions of the skin, three AKs and two AK+CIS, from three patients were short-term cultu

Temperament, character, and self-esteem in relation to occupational performance in individuals with schizophrenia

Occupational therapy researchers have tried to clarify the links between occupation and statelike characteristics, such as people's experienced health, disability, and quality of life. However, to fully examine the spectrum of potential influences on occupation, trait-like features should also be investigated. This study focused on personality and self-related factors, in terms of temperament, cha

A sequence variation in the human cystatin D gene resulting in an amino acid (Cys/Arg) polymorphism at the protein level

A polymorphism in the coding region of the human cystatin D gene has been detected by direct sequencing of amplified DNA from different individuals. The variation, resulting from a T/C transition in exon 1 of the gene, causes an amino acid variation, Cys/Arg, at the protein level. An allele-specific oligonucleotide hybridization assay was developed and used to demonstrate this polymorphism in the

Proton magnetic shielding tensor in liquid water

The nuclear magnetic shielding tensor is a sensitive probe of the local electronic environment, providing information about molecular structure and intermolecular interactions. The magnetic shielding tensor of the water proton has been determined in hexagonal ice, but in liquid water, where the tensor is isotropically averaged by rapid molecular tumbling, only the trace of the tensor has been meas

Caring power : coercion as care

The article analyses the compulsory care of drug misusers in Sweden. An historical analysis of this field of work as a part of the Swedish welfare state highlights historically changing legislations, institutions, understandings and practices. Following Foucault, it is argued that it is impossible to distinguish between power and care and that confusion about coercive care is a result of not ackno

Hospital stay related to TNM-stage and the surgical procedure in primary breast cancer

In Sweden from 1980 to 1995 there was an overall decrease of 56% in mean length of stay (MLOS) for surgical curative breast cancer treatment. The objective of this study was to separate the possible impact of tumour size and lymph node dissemination and changes in surgical procedures. All women diagnosed (n=13 290) with breast cancer between 1982 and 1995 were selected from the Southern Swedish Tu

"Seed money" and publication output in Mexican research: A case study of IFS grantees

This study assesses the effect of grants given to young Mexican researchers by the International Foundation for Science (IFS) on the development of their academic careers through an analysis of their publication output. Since 1974 IFS has supported similar to 4000 young scientists in developing countries conducting relevant and high quality research on the sustainable use of biological natural res

Relative Clauses in Kammu and the Keenan-Comrie Hierarchy

There are three relativization strategies in the Austroasiatic lang Kammu: (1) deletion of the relativized NP, (2) deletion & change of word order, & (3) pronominalization of the relativized NP. The use of these strategies for the six positions (subject, direct O, indirect O, oblique NP, genitive, & O of comparison) on the relativization hierarchy proposed by E. Keenan & B. Comrie

Sharers in Divine Nature : 2 Peter 1:4 in Its Hellenistic Context

Popular Abstract in Swedish Avhandlingen är ett teologiskt studium av ett i biblisk litteratur säreget uttryck som angår livets mening: ”att ni skall bli delaktiga av gudomlig natur” (2 Petrus 1:4). Efter en analys av 2 Petrus 1:1-11 undersöks några utvalda texter tillgängliga vid första århundradet som behandlar temat ”att bli delaktiga av gudomlig natur”. Jämförande material utgörs av Gamla testThis book offers a theological study of an expression unique in biblical literature concerning the purpose of life: “that you might become sharers in divine nature” (2 Peter 1:4). Following an analysis of the text-immanent features in 2 Peter 1:1—11, the study delineates comparable notions of “sharers in divine nature” in selected writings that were current in the first century and contrasts these

Supported liquid membrane work-up of blood plasma samples coupled on-line to liquid chromatographic determination of basic antidepressant drugs

An automated sample pretreatment of human blood plasma for liquid chromatographic determination of three antidepressant drugs, dibenzepine; a tricyclic antidepressant (TCA), reboxetine; a selective noradrenaline reuptake inhibitor (SNRI) and fluvoxamine; a selective serotonin reuptake inhibitor (SSRI), based on supported liquid membrane (SLM) for unsurpassed sample clean-up and analyte enrichment,

The pseudotetrasaccharide acarbose inhibits pancreatic islet glucan-1,4-alpha-glucosidase activity in parallel with a suppressive action on glucose-induced insulin release

The pseudotetrasaccharide acarbose, previously known as a potent inhibitor of intestinal alpha-glucoside hydrolases, was investigated with regard to its influence on islet lysosomal enzyme activities and the insulin secretory processes. We observed that acarbose was a potent inhibitor of mouse islet lysosomal acid glucan-1,4-alpha-glucosidase activity, EC50 approximately 5 mumol/l, as well as of a

Selective pressurized liquid extraction of PCBs from food and feed samples: Effects of high lipid amounts and lipid type on fat retention

Fat free extraction of polychlorinated biphenyls (PCBs) from fat containing food and feed matrices was achieved by selective pressurized liquid extraction using sulphuric acid impregnated silica inside 100 mL extraction cells on a Dionex ASE300. Data were compared to previous publications where extractions had been performed on a Dionex ASE200, with 33 mL cells and a Dionex ASE300, with 34 mL. In

LKB1 is a master kinase that activates 13 kinases of the AMPK subfamily, including MARK/PAR-1

We recently demonstrated that the LKB1 tumour suppressor kinase, in complex with the pseudokinase STRAD and the scaffolding protein MO25, phosphorylates and activates AMP-activated protein kinase (AMPK). A total of 12 human kinases (NUAK1, NUAK2, BRSK1, BRSK2, QIK, QSK, SIK, MARK1, MARK2, MARK3, MARK4 and MELK) are related to AMPK. Here we demonstrate that LKB1 can phosphorylate the T-loop of all
