Massive CO 2 removals will be necessary to avoid climate tipping. Comparing with past, current and future carbon stocks flows reveals the importance of avoiding fossil emissions completely developing scalable technical solutions.

Many chemical and physical systems show self-sustained oscillations that can be described by a set of nonlinear differential equations. The system enters oscillatory behavior an intrinsic instability leads to bifurcation. We analyze conducting present oscillating response under application external voltage or current. Phenomena like electrochemical corrosion the spiking biological neuron are we...

Quantitative information about the response of seedling emergence totemperature for safflower (Carthamus tinctorius L.) is rare. The main objective ofthe present study was to develop a model for predicting days to emergence forsafflower as influenced by the temperature. In this regard, a field experiment with arange of sowing dates and four safflower cultivars were conducted to describe theresp...

The reliability function of variable-rate Slepian-Wolf coding is linked to the reliability function of channel coding with constant composition codes, through which computable lower and upper bounds are derived. The bounds coincide at rates close to the Slepian-Wolf limit, yielding a complete characterization of the reliability function in that rate regime. It is shown that variable-rate Slepia...

We present new results obtained from the modeling of a tulip-like variable curvature mirror (VCM) in case central force that reacts to its contour. From Nastran finite element analysis, we shows 3-D optimizations, using non-linear static flexural option, with an appropriate solution sequence, provide accurate VCM thickness distribution. This allows us take into account boundary conditions, incl...

Background: Cereals are the most staple foods in human diet and the main components of the daily diet. This work was designed to determine the level of essential and non-essential elements, the in vitro bioavailability, interrelationship, and associated health risk in consumed cereal grains in Nigeria to assess their safety and wholesomeness. Methods: The contents of phytate, oxalate, and some...
