Objectives: Polycrystalline diamond compact (PDC) is an ultra-high hardness composite material made from polycrystalline diamond (PCD) and cemented carbide through high temperature and high pressure sintering.PDC is widely used in oil and gas extraction, geothermal development, and coal field drilling.As drilling goes deeper, the formation pressure
Forest fires occur as a result of natural and man-made Lunge Pads causes.It is known that particles heated to high temperatures are a common source of high temperature.The purpose of the work is the physical simulation of the typical forest fuel ignition (spruce needles ignition) by the carbon particle heated to high temperatures and the identifica
Water use behaviour and efficiency are essential topics regarding water scarcity.Water is a life-sustaining resource used for various activities within the three primary sectors: agricultural, industrial, and domestic.Increasing competition among these sectors could affect the availability and sustainability of water use.The higher demand for agric
It is well known that polar bears feed on vegetation.Here, I report novel observations of polar bears grazing on polar scurvy grass (Cochlearia groenlandica) at the foot of a large seabird colony on a cliff on Spitsbergen, Svalbard, in the summers of 2005, 2006, 2009, 2014 and 2015.Why they choose such energy-costly climbing to feed on plants is no
Introduction: Pharmaceutical companies as well as food and cosmetics manufacturers are legally required to provide a shelf-life label on their products packaging as part of their stability Trunk study report.There are different recommended software like R software package and SAS which can perform as shelf-life estimating tools for analyzing the da
