The article describes problems of welding heterogeneous welds be specific heat resistant steel X15CrNiSi20-25 with cobalt alloy Stellite 6. Heterogeneous are produced by GTAW (141 according to standard EN ISO 4063) method. major goals the experiment were performing preliminary specifications (pWPS) for a welded part. Further was necessary this weldment set parameters on mechanical testing.

Acoustic Tweezer for Heterogenous Assembloids Patterning Heterogeneous assembloids with predesigned patterns can be constructed sequentially to explore polarized tissue development or disease metastasis in multi-organs. In article 2200288, Hairong Zheng, Xiao Zhang, Teng Ma, and co-workers present a multifunctional acoustic tweezer system that manipulates single organoid construct non-invasivel...

C media, particularly blogs, can help companies increase the visibility of their products without spending millions of dollars in advertising. Although a number of companies realize the potential of blogs and encourage their employees to blog, a good chunk of them are skeptical about losing control over this new media. Companies fear that employees may write negative things about them and that ...

The photocatalytic decomposition of 2-, 3and 4-chlorobenzoic acids (2CB, 3CB and 4CB, respectively) with TiO2 loaded on HZSM-11 zeolite was investigated. The optimum decomposition rate of 2CB was obtained with TiO2/HZSM-11(30%) (TiO2 30 wt.%) catalyst at a concentration of 1 mg mL. 2CB and 3CB decompose at similar rates, but 4CB remains adsorbed on TiO2/HZSM-11(30%) without further degradation....

Dowex-50W-hyodrgen ion exchange resin was used as a reusable catalyst for the synthesis of oxazoline, imidazoline and thiazoline derivatives through condensation reaction between arylnitriles and 2-aminoalcohol, ethylenediamine or 2-aminoethanthiol. This process provides several advantages such as excellent yields of the products, simple operation, convenient separation and inexpensive and recy...

This paper first describes an empirical model to characterize the deactivation of a catalyst used in the production of a specialty chemical based on actual plant data. This model is then used in a novel multiperiod MINLP optimization formulation that incorporates the empirical model in order to determine the optimal catalyst replacement policy and meet time varying product demand.

In the study of epidemic spreading two natural questions are: whether the spreading of epidemics on heterogenous networks have multiple routes, and whether the spreading of an epidemic is a local or global behavior? In this paper, we answer the above two questions by studying the SIS model on heterogenous networks, and give the global conditions for the endemic state when two distinct routes wi...

To provide a common ground for the comparison of real-time multicore synchronization protocols we developed a framework that supports heterogenous levels of abstraction for simulated functionality and simulated timing. Our intention is to make the simulator available to the real-time research community and industrial users. For the latter we initially focus on automotive real-time systems. This...
