Cold Start on Diesel Engine: Is Low Compression Ratio Compatible with Cold Start Requirements?

SAE International Journal of Engines, 2008
<div class="htmlview paragraph">Future emission standards for Diesel engine will require a drastic reduction of engine-out NOx emissions with very low level of particulate matter (PM), HC and CO, and keeping under control fuel consumption and combustion noise.

Lime Requirement Methods for Cold‐Region Soils

Soil Science Society of America Journal, 1981
Abstract Virgin acid soils collected in Alaska between 58 and 66° N Lat. were equilibrated with increasing increments of CaCO 3 to determine quantities of lime required to neutralize the acidity.

DRAWING REQUIREMENTS OF COLD ROLLED SHEET STEEL

SAE Technical Paper Series, 1954
<div class="htmlview paragraph">It is not the purpose of this report to dwell extensively on the physical properties of the subject material. But, rather with the steel defects that are a vital factor from the stand-point of efficiency and economy to both the producer and user of sheet steel.

Cathodic Protection in Cold Seawater – Current Density Requirements

CORROSION 2009, 2009
Abstract Cathodic protection combined with organic coating is the normal way to protect structures exposed to seawater against corrosion. The oil and gas industry is moving to deeper waters with pipelines and production systems located on the sea bottom, often far away from shore.

Theoretical Requirements and Real Benefit of Cold Protective Clothing for Order-Pickers in Deep Cold

2018
In a deep-cold working environment with variable physiological stress and considering individual thermoregulatory capacities, cold protective clothing must maintain the users’ body core and skin surface temperature on an acceptable level. In order to evaluate the cold protective clothing used, physiological effects of order-picking in a cold store (−24

Comfort and thermoregulatory requirements in cold weather clothing

2009
The human body has different thermoregulatory mechanisms to fight the cold, like the constriction of blood vessels or shivering. Wearing clothing is a behavioural means to prevent excessive heat loss from the body. In the cold, the function of the clothing is to reduce the heat transfer to the environment, especially by limiting the convective heat ...

Magnetically guided cold atom gyroscopes and their photonic requirements

SPIE Proceedings, 2015
This paper focuses on several key ideas to using atom interferometry to detect rotation within the context of an atom trap or “guide”. I discuss shortcomings of traditional free space light pulse atom interferometry that the advantages of guided light pulse atom interferometry can mitigate and under what conditions that strategy is possible.

Cottonwood Flowering as Related to Cold Requirement of Flower Buds

Forest Science, 1964
Abstract The cold requirement of Populus deltoides Bartr. in central Mississippi was investigated by forcing flower-bud-bearing branches collected in November, December, January, and February. Rapidity of flowering response increased from November to February.
