The Brazilian state oil company Petrobras has picked a site in the cities of Itaborai and Sao Goncalo,state of Rio de Janeiro,to build a previously announced 6.5 billion petrochemical complex(C&EN,Nov.14,2005,page 38).Petrobras says the first phase is a complex that will turn heavy oil into...
Although the physical and chemical properties of biofuels make pipeline transportation more challenging, the industry is looking for ways to overcome these obstacles. Top Ethanol Producing Countries The United States and Brazil combine to produce about 85% of theworld’s annual supply of ethanol. ...
Note that there are some very highTS80mvalues, stating more than 20 years of stability (Supplementary Fig.2, SI). That may seem long, but is the result of stable devices measured under harsh conditions, as shown in Supplementary Table3(SI). The heuristics here used assumes that a 1 h...
HOW Having led other food accelerators, we went back to the drawing board and created a new approach to make sure you get the support you need to succeed. Our program combines capital and partnership in the form of mentor engagement, team building, peer support and access to an active netwo...
[Techie aside: Complex realitieslook like Shannon white noise, but in terms of deeper structure, their Kolmogorov-Chaitin complexity is low relative to their Shannon entropy; they are like pseudo-random numbers orπ, rather than real random numbers; I wrote atwo-partserieson this long ago, tha...
With the integration of an increasing number of components into blockchain systems, such as RFID, smart sensors, smart robots, biometric data, IoT, and big data, the underlying logic and implementation may become more complex. In addition, although blockchain technology is already widely applied ...
The formulas of AIC for determining the system order of interactions among the i-th protein and the q-th gene are given as below: 𝐴𝐼𝐶(𝑌𝑖)=log(𝜌̂2𝑖,𝑃)+2(𝑌𝑖+1)𝑁where 𝜌̂𝑖,𝑃=(𝑃𝑖−(Ξ𝑖,𝑃⋅𝜑̂𝑖,𝑃))𝑇(𝑃𝑖−(Ξ...
Ananalogycan be made with thechemical elements. In the 19th century most chemists believed the elements to be strictly conserved quantities; althoughoxygenand hydrogenatomscan be combined to formwatermolecules, the original oxygen and hydrogen atoms can always be recovered by chemical or physical means...
“not cancer”, we need deep medical expertise, and it is often hard to find such domain experts who can credibly identify and label a specific type of data such as tumors or chemical formulas [56]. Finally, (iii) access limitation is also a pain point for acquiring more data. ...
Although it seems like a long time ago, in reality Mexico had the first stock exchange almost 300 years after the first one was born: the Amsterdam Stock Exchange, founded in 1602. The Commodity Futures Trading Commission Open Meeting scheduled for Wednesday, November 1, 2023 has been canceled...
