The process of harvesting wood greenery in the Far North presents some technological and organisational challenges. Logging operations are carried out under difficult conditions, including unstable weather, low land development, insufficient transport infrastructure, high environmental requirements. This article deals with peculiarities coniferous greenwood logging conditions North. An analysis...

Involvement of the heart in hypothyroidism (myxcedema heart disease) was first recorded by Zondek in 1918. Since then attention has been focused on the histological characteristics of the cardiac lesion and the clinical manifestations of myxcedema heart disease (Fahr, 1925; Campbell and Suzman, 1934; Means, 1937; Fournier, 1942; Bustamante et al., 1955; Hamilton and Greenwood, 1957). Myocardial...

Different brake pad materials are produced, each with their unique composition in the recent past, yet performing same task and claiming to be better than others. The article provides references for different automotive pads subjected various operating conditions. present investigation develops an analytical approach estimating COF contact radius disc-brake pads, which can used design efficient...

Abstract Maria-Theresia Walach, Melanie Cookson-Carter and Rachel Roberts discuss the life work of Captain William Nelson Greenwood, whose legacy includes a mysterious tide calculator

Understanding DC electrical conductivity is crucial for the study of materials. Macroscopic can be calculated from first principles using Kubo–Greenwood equation. The procedure involves finding thermodynamic limit current response to an electric field that slowly switched on, and then taking switching rate zero. We introduce a nonlinear extrapolation executed in systems with periodic boundary c...

This work analyzes the electron mobility in few-layer MoS2-based metal–insulator-semiconductor field-effect transistors. To do it, the Poisson and Schrödinger equations are self consistently solved using the effective mass approximation to model the six equivalent K valleys characteristic of multilayer MoS2. The mobility is calculated using the Kubo-Greenwood approach under the momentum relaxat...

The need to invest in the regulatory environment to support biotechnology innovation is urgent, says Jim Greenwood, president and CEO, Biotechnology Industry Organization.

This study seeks to validate a search protocol of ill health-related terms using Twitter data which can later be used to understand if, and how, Twitter can reveal information on the current health situation. We extracted conversations related to health and disease postings on Twitter using a set of pre-defined keywords, assessed the prevalence, frequency, and timing of such content in these co...
