Sugarcane bagasse was subjected to steam pretreatment impregnated with hydrogen peroxide. Analyses were performed using 2(3) factorial designs and enzymatic hydrolysis was performed at two different solid concentrations and with washed and unwashed material to evaluate the importance of this step for obtaining high cellulose conversion. Similar cellulose conversion were obtained at different condi

A majority of the machining processes in the industry of today is performed using position-controlled machine tools, where conservative feed rates have to be used in order to avoid excessive process forces. By instead controlling the process forces, the feed rate, and consequently the material removal rate, can be maximized. In turn, this leads to decreased cycle times and cost savings. Furthermor

Mineralkvävegödsel är en av förutsättningarna för de höga skördenivåer som uppnåtts i det industrialiserade, moderna jordbruket. I Sverige finns idag ingen inhemsk produktion av mineralkvävegödsel, utan hela efterfrågan tillgodoses med import från utlandet. Produktionen är idag baserad på fossila resurser, vilka används både som råvara för produktionen och som energi för att driva processerna. Vi Mineral nitrogen fertilizer is one of the main reasons for the high yields in modern, industrial agriculture. There is currently no production of mineral nitrogen fertilizer in Sweden – the entire demand is met by imports from abroad. Global production is at present based on fossil resources, which are used both as raw materials for the production and as energy to fuel the process. We are thus dep

Popular Abstract in Swedish Hårfrisörer utsätts dagligen för en mängd kemikalier på arbetet. Många frisörer drabbas därför av luftvägsbesvär vilka ofta kan kopplas till hårblekningsmedel. Blekningsmedlen innehåller bland annat så kallade persulfater. Dessa tros vara en av huvudorsakerna till luftvägsbesvären. Flera studier har visat att persulfater kan ge symptom från luftvägarna såsom hösnuva ellHairdressers have an increased risk for developing airway symptoms e.g. asthma and rhinitis. Persulfate salts, which are oxidizing agents present in bleaching powder, are considered to be important causal agents for these symptoms. The underlying mechanisms are unclear and efficient tools for risk assessment and diagnosis are scarce. The general aim of this thesis was to measure proteomic changes,

AIM AND OBJECTIVE: To describe the study design of a randomised controlled trial with the aim of comparing two different regimes for children with newly diagnosed type 1 diabetes; hospital-based care and hospital-based home care. BACKGROUND: Procedures for hospital admission and sojourn in connection with diagnose vary greatly worldwide and the existing evidence is insufficient to allow for any c

Colonization of new habitats through dispersal of phytoplankton cysts might be limited, if resident populations outcompete invaders during germination. We reciprocally transferred Gonyostomum semen (Raphidophyceae) cysts from three lakes into native and foreign waters originating from the respective habitats. Germination rate and germling growth were impacted by water origin, but there was no pref

Resilience is often promoted as a boundary concept to integrate the social and natural dimensions of sustainability. However, it is a troubled dialogue from which social scientists may feel detached. To explain this, we first scrutinize the meanings, attributes, and uses of resilience in ecology and elsewhere to construct a typology of definitions. Second, we analyze core concepts and principles i

The electronic structure of the lowest-lying electronic states of W-2 were investigated at the CASPT2 level. The ground state is a X-1 Sigma(+)(g) state, followed by the a(3)Delta(u), b(3)Sigma(+)(u) and A(1)Delta(u) electronic states. Seven low-lying Omega-states were computed: (1)0(g)(+), (2)3(u), (3)2(u), (4)1(u), (5)0(u)(-), (6)1(u), and (7)2(u), with the ground state corresponding to the (1)0

ABSTRACT The overarching aim of this sociology of law study is to explore internal processes at a court to get deeper knowledge of norms within this legal organisation. The point of departure is a specific research interest in studying professional norms on ‘good treatment’ in a local court. Another aim is to study the importance that the internal professional norms have on the external treatment

The report outlines the conditions and results of an evacuation experiments performed on 1-3 July 2014 in the Northern Link road tunnel in Stockholm. The aim was mainly to investigate how people can best be led to an opposite tunnel side during escape in a smoke-filled tunnel. The experiment also aimed to quantify the speed at which people move in smoke-filled tunnel environments (i.e. at reduced

Compared to other insect groups, libellulids have a rather high mean number of ovarioles. In addition, the mean ovariole diameter differs greatly between and within species. In general, 2 different types of ovariole arrangement exist: (1) all developing oocytes mature and equal in size; in some species without, and in others with, surrounding connective tissue and (2) oocytes displaying gradual ma

OBJECTIVE: COMP primarily found in cartilage is thought to be an important regulator of assembly and maintenance of the fibrillar collagen I and II networks. Recently COMP was shown to be produced by skin fibroblasts from patients with systemic sclerosis (SSc, scleroderma). The purpose of this study was to examine whether COMP is released from skin to serum in SSc patients, and may serve as indica

Background: Old age at diagnosis is associated with poor survival in colorectal cancer (CRC) for unknown reasons. Recent data show that colonoscopy is efficient in preventing left-sided cancers only. We examine the association of Tumor Node Metastasis (TNM) classes with diagnostic age and patient characteristics. Methods: The Swedish Family-Cancer Database has data on TNM classes on 6,105 CRC aden
