Surface topography characterization of brass alloys: lead brass (CuZn39Pb3) and lead free brass (CuZn21Si3P)

Manufactured surfaces usually consist of topographical features which include both those put forth by the manufacturing process, and micro-features caused by disturbances during this process. Surface characterization basically involves study of these features which influence the functionality of the surface. This article focuses on characterization of the surface topography of machined lead brass

Imprinting of microorganisms for biosensor applications

There is a growing need for selective recognition of microorganisms in complex samples due to the rapidly emerging importance of detecting them in various matrices. Most of the conventional methods used to identify microorganisms are time-consuming, laborious and expensive. In recent years, many efforts have been put forth to develop alternative methods for the detection of microorganisms. These m

Autofluorescence guided biopsy for the early diagnosis of bladder carcinoma

Purpose We validate the usefulness of laser-induced autofluorescence for the detection of bladder carcinoma. Materials and Methods We obtained and analyzed fluorescence spectra from 75 patients in whom bladder cancer was suspected. Tissue fluorescence was excited by a nitrogen laser using a quartz optical fiber placed in gentle contact with the area of interest. The laser-induced autofluorescence

Essays on Social Norms and Economic Change

Experimental manipulation suggests effect of polyandry but not mate familiarity on within-pair aggression in the social skink, Liopholis whitii

Abstract: Long-term monogamy is a key characteristic of family living across animals. The evolutionary maintenance of long-term monogamy has been suggested to be facilitated by increased reproductive coordination as a result of mate familiarity, leading to increased reproductive success. However, such effects can be compromised if females mate outside the pair bond (e.g. female polyandry), introdu

Hälsorelaterad miljöövervakning Cancerframkallande ämnen i tätortsluft : Personlig exponering och bakgrundsmätning Malmö 2014

Denna studie har syftat till att kartlägga allmänbefolkningens exponering för vissa luftburna cancerframkallande ämnen: bensen, 1,3-butadien, formaldehyd, kvävedioxid, kväveoxid samt ozon. Undersökningen genomfördes i Malmö under hösten 2014 och inkluderade totalt 42 slumpvis utvalda malmöbor i åldrarna 20-50 år. Samtliga mätningar, bortsett från formaldehyd, upprepades på 22 personer. Tjugo av de

Constructing equality? : Women’s wages for physical labor, 1550-1759

This paper combines new archival data on women’s wages from southern Sweden with published series from Stockholm in order to create a series of early modern female construction workers’ wages between the middle of the sixteenth and middle of the eighteenth centuries. This paper finds that women had relatively high relative wages in the later part of the sixteenth century, with an increasing wage g

The growing world of small heat shock proteins : from structure to functions

Small heat shock proteins (sHSPs) are present in all kingdoms of life and play fundamental roles in cell biology. sHSPs are key components of the cellular protein quality control system, acting as the first line of defense against conditions that affect protein homeostasis and proteome stability, from bacteria to plants to humans. sHSPs have the ability to bind to a large subset of substrates and

Advancements of 2D speckle tracking of arterial wall movements

Cardiovascular diseases are the leading cause of death worldwide. In order to improve the diagnostics and facilitate early interventions of cardiovascular diseases, knowledge about the physiology of the vascular system in both healthy subjects and in subjects with vascular disease is needed. In order to learn more about the physiology of the vascular system and possibly predict cardiovascular dise
