Silk yarns were dyed by using commercial basic, reactive and pre-metallised acid dyes. An aftertreatment with a commercial synthetic tanning agent (syntan) was applied to the dyeings and the aftertreated dyeings were further treated with metal salts in an attempt to improve wash fastness properties. When all samples (untreated, syntanned and syntanned/ backtanned speciments) were subjected five...

In the 1970s, a Baltimore city senator who also owned a tavern backed legislation that helped his business. Accused of having a conflict of interest, Joseph J. Staszak, responded, ‘‘What conflict of interest? How does this conflict with my interest?’’ [1]. According to the Institute of Medicine, a conflict of interest is ‘‘a set of circumstances that creates a risk that professional judgment or...

There is a growing public concern over the potential accumulation of heavy metals in soil, owing to rapid industrial development. In an effort to describe the status of the pollutions of soil by industrial activities, relevant data sets reported by many studies were surveyed and reviewed. The results of our analysis indicate that soils were polluted most significantly by metals such as lead, zi...

New manufacturing technologies are developed fast in order to keep up with the market demands, both in the field of metal cutting and metal forming. The Asymmetric single point incremental forming (ASPIF) is a manufacturing technology with a high degree of novelty, which allows the user to manufacture complex parts by metal forming, using only a punch and an active plate without the need of usi...

The implementation of economic projects by targeting the subsidies can have a great effect on the cost competitiveness of the industries and their products. The global steel industry has been considered as a basic key industry in the industrialized countries. It is also among the industries that may be seriously affected by the enforcement of subsidies. This industry, requiring energy and high-...

The microbial contamination of water miscible metalworking fluids (MWFs) is a serious problem in metal industry. A good maintenance of MWF re-circulation systems can extend the lifetime of coolants and ensure the quality of the tools produced. In MWFs, as in the other water-based environments, microorganisms usually live in the form of biofilms, the communities of bacteria and fungi attached to...

when the past observations are correlated with future observations and their correlation is significant, the time series has long memory. in this paper the contagion effect of volatilities, with consideration of long-run effect, is investigated. the basic model is bekk (1, 1) and fbekk (1,d,1), model extended long-run memory parameter (d) is considered and estimated. furthermore in this paper p...

In knowledge-based economy, knowledge has a public good and non-rivalry nature. Firms build their own knowledge stock not only by means of internal R&D and collaboration with partners, but also by means of previously spilled over knowledge of other firms and public research laboratories (such as universities). Firms based on their absorptive capacity, and level of intra-industry and extra-indus...

< p>Mg-Fe bi-metal oxide was prepared and utilized as a magnetized renewable solid base catalyst for formation of 2-aminothiophenes by means of Gewald’s reaction. The prepared heterogeneous basic solid catalyst can be separated by a magnet and reused without considerable wastage in this activity. The structure of the aforementioned magnetized basic nano-catalyst was studied by XRD (X-ray diffra...

This paper presents a review of the recent work done on annealing dissimilar metal welded by SMAW, with focus improvement microstructure and mechanical properties specimen. Annealing is used in industry to improve desired such as increasing machinability, strength material, hardness removing stress from metal. The papers for investigation this were considered 2010 date 2021. A total 20 research...
