On the Analytical Representation of Chip Area and Tool Geometry when Oblique Turning with Round Tools. Part 1: Chip Area Parameters under Variation of Side and Back Rake Angle

Chip area parameters, such as undeformed chip thickness, equivalent chip thickness, contact edge length, etc., along with tool angles are among defining for the mechanical and thermal conditions of the cutting process. This paper considers the case of external turning with a round insert under variation, in wide range, of back and side rake angles and their influence on the main chip area and surf

High-Quality Metal-Organic Framework Ultrathin Films for Electronically Active Interfaces.

Currently available methodologies arguably lack the exquisite control required for producing metal-organic framework (MOF) thin films of sufficient quality for electronic applications. By directing MOF transfer with self-assembled monolayers (SAMs), we achieve very smooth, homogeneous, highly oriented, ultrathin films across millimeter-scale areas that display moderate conductivity likely due to e

Cloning, expression and characterization of a versatile Baeyer-Villiger monooxygenase from Dietzia sp. D5.

A novel BVMO encoding gene was identified from a draft genome sequence of a newly isolated strain of Dietzia. Analysis of the protein sequence revealed that it belongs to a group of BVMOs whose most characterized member is cyclopentadecanone monooxygenase (CPDMO). The gene was PCR amplified, cloned and successfully expressed in E. coli. The expressed recombinant enzyme was purified using metal aff

Musikupplevelser - psykologiska synpunkter

Artikeln ger en översikt över hur man med socialpsykologiska teorier kan närma sig en beskrivning av upplevelser av musik. En tentativ slutsats är att musik är en resurs för identitetsskapande där kognitiva, emotionella och sociala faktorer är aktiva.

Operator auditory perception and spectral quantification of umbilical artery Doppler ultrasound signals

OBJECTIVE: An experienced sonographer can by listening to the Doppler audio signals perceive various timbres that distinguish different types of umbilical artery flow despite an unchanged pulsatility index (PI). Our aim was to develop an objective measure of the Doppler audio signals recorded from fetoplacental circulation in a sheep model.METHODS: Various degrees of pathological flow velocity wav

Treatment of brain tumours with electroporation and bleomycin in an in vivo rat model

The purpose of the study was to examine the possibilities of prolonging the life of rats with brain tumours using electroporation only while conducting impedance scans to evaluate the rate of electroporation. During the experiments, the treated rats in the first batch had tumors grow for 14 days and were then given electroporation with 8 + 8 exponential pulses at 800 v/cm, and 15 micro-F. Three of

The role of quantitative mass spectrometry in the discovery of pancreatic cancer biomarkers for translational science.

In the post-genomic era, it has become evident that genetic changes alone are not sufficient to understand most disease processes including pancreatic cancer. Genome sequencing has revealed a complex set of genetic alterations in pancreatic cancer such as point mutations, chromosomal losses, gene amplifications and telomere shortening that drive cancerous growth through specific signaling pathways

Managing the needs of end-users in the design and delivery of construction projects

Purpose – The two-fold purpose of this paper is identifying areas of difficulty in managing the needs of end-users in the course of the design and delivery of construction projects and suggesting possible solutions. Design/methodology/approach – The focus of the paper is the interaction between three principal parties: end-users, project leader (a selected end-user) and facility planner (a facil

Rasagiline ameliorates olfactory deficits in an alpha-synuclein mouse model of Parkinson's disease.

Impaired olfaction is an early pre-motor symptom of Parkinson's disease. The neuropathology underlying olfactory dysfunction in Parkinson's disease is unknown, however α-synuclein accumulation/aggregation and altered neurogenesis might play a role. We characterized olfactory deficits in a transgenic mouse model of Parkinson's disease expressing human wild-type α-synuclein under the control of the

Laser absorption spectroscopy of water vapor confined in nanoporous alumina: wall collision line broadening and gas diffusion dynamics.

We demonstrate high-resolution tunable diode laser absorption spectroscopy (TDLAS) of water vapor confined in nanoporous alumina. Strong multiple light scattering results in long photon pathlengths (1 m through a 6 mm sample). We report on strong line broadening due to frequent wall collisions (gas-surface interactions). For the water vapor line at 935.685 nm, the HWHM of confined molecules are ab

Burchnall-Chaundy Theory for Ore Extensions

We begin by reviewing a classical result on the algebraic dependence of commuting elements in the Weyl algebra. We proceed by describing generalizations of this result to various classes of Ore extensions, including both results that are already known and one new result.

Frail elderly patients' experiences of information on medication. A qualitative study

Background: Older patients generally have only poor knowledge about their medicines. Knowledge is important for good adherence and for participating in decisions about treatment. Patients are entitled to be informed on an individual and adequate level. The aim of the study was to explore frail elderly patients' experiences of receiving information about their medications and their views on how the

Brachyradia, a new genus of the tribe Exechiini (Diptera: Mycetophilidae) from the Oriental and Australasian regions

Brachyradia, new genus, is proposed and described for two new species of the tribe Exechiini (Diptera: Mycetophilidae) from the Oriental and Australasian regions. The type species, Brachyradia asianca, new species, is described from Thailand, Malaysia, and Indonesia (Sulawesi), and a second species, Brachyradia australis, new species, from Indonesia (Sulawesi) and Papua New Guinea. The systematic

Impact of the first tumor response at eight weeks on overall survival in metastatic breast cancer patients treated with first-line combination chemotherapy

The aim of this was to determine whether the change of size observed at the first response evaluation after initiation of first-line combination chemotherapy correlates with overall survival (OS) in patients with metastatic breast cancer (MBC). The change in size of tumors derived from measurements according to Response Evaluation Criteria In Solid Tumors (RECIST) at the first evaluation on comput
