A prototype distillation and storage system with recycle for producing ultrapure water was monitored for bacteriological contamination during a period of 24 months. Naturally occurring Pseudomonas aeruginosa and P. cepacia were found to grow rapidly to levels of about 10(5)/ml in water taken from the storage reservoir and also in commercially prepared distilled water. The system was found to el...
Most Java programmers would agree that Java is a language that promotes a philosophy of “create and go forth”. By design, temporary objects are meant to be created on the heap, possibly used and then abandoned to be collected by the garbage collector. Excessive generation of temporary objects is termed “object churn” and is a form of software bloat that often leads to performance and memory pro...
We analyze recycling as firm's optimal strategy in a duopolistic market, under the cases of linear economy (no technology), semi-circular (one firm recycles), and circular (both firms recycle). Furthermore, our analysis will be separated into two cases: when only one recycles, then it can either choose to use recycled material its production or sell part (or all) other firm; similarly, if both ...
This project deals with the problem at the core of chemical processes, that of creating a structure for the reaction-separation-recycle system. New methods have been developed for the synthesis of such structures capable of screening a wide range of options and taking account of all of the trade-offs simultaneously. For the first time these methods are capable of fully taking into account the i...
Aiming at improving the performance of existing detection algorithms developed for different applications, we propose a region regression-based multi-stage class-agnostic detection pipeline, whereby the existing algorithms are employed for providing the initial detection proposals. Better detection is obtained by exploiting the power of deep learning in the region regress scheme while avoiding ...
Catalytic synthesis can be achieved by using either homogeneous or heterogeneous organometallic complexes, or homogeneous enzymatic biocatalysts. However, each of these methods offers advantages and disadvantages that must be balanced cautiously. Homogeneously catalyzed reactions are highly efficient in terms of selectivity (i.e. regioselectivity, enantiomeric excesses) and reaction rates, due ...
The article presents an approach to design tubular reactors in recycle systems, based on non-linear analysis. A pseudohomogeneous plug-flow reactor model is used. It is assumed that the separation unit delivers product and recycle streams with fixed composition. The stand-alone reactor has a unique stable steady state. The coupled reactor /separation /recycle system shows four types of conversi...
After neurotransmission, neurons internalize and recycle the membrane components of synaptic vesicles remarkably quickly; they may have a 'rebuilt, turbo-charged' endocytic engine to achieve these speeds.
