This short review describes various types of anti-corrosion additives of water-soluble metal working fluids for aluminum alloy materials. It is concerned with synthetic additives classified according to their functional groups; silicone compounds, carboxylic acids and dibasic acids, esters, Diels-Alder adducts, various polymers, nitrogen compounds, phosphoric esters, phosphonic acids, and other...

Tartrazine (FD&C Yellow No. 5) and other allowed certified color additives may have an exacerbating effect in chronic urticaria and asthma sufferers. In the individual patient the only way to determine their relevance is to administer test doses. By altering doses, timing and substances and by interspacing controls a battery of tests has been developed. Methods of testing for sensitization to f...

While accessing to the European Union the Republic of Finland obtained a derogation enabling it to maintain the ban on its territory of the use of tylosin and spiramycin as feed additives. According to the Treaty of Accession, Finland was due to provide its request for adaptation of Community legislation before 31 December 1997, which should be accompanied by a detailed scientific statement of ...

Introduction Various microorganisms, enzymes, nutritive and chemical compounds have been added to forages to maintain or improve the nutritive value of a crop as silage (Kung et al., 2003). As is the nature of most biological systems, there is considerable variation in the outcome of using these additives. This paper will briefly discuss some universal and specific challenges that these additiv...

Effect of different additives like wax (polyethylene), stearic acid, calcium stearate, alum, naphthalene and camphor was studied on the burning efficiency of paraffin-candles. It was found that burning efficiency, physical strength and smoke producing capacity of candles were influenced by even adding these additives in very small quantities. Burning rates were calculated while smoke generated ...

T production of fish feed additives for the aquaculture industry is a thriving sector in China. These natural substances are being used for several purposes including the enhancement of the immune systems of farmed fish, promoting growth, attaining the desired flesh and skin pigmentation, as well as improving the organolepctic properties of the farmed product. At the same time, the use of such ...

Additives play a decisive role in crystallization processes. We survey the ongoing efforts in the realm of additive-controlled crystallization. Emphasis is placed on the commonly used and most studied types of additives and their influences on prenucleation, stabilization of amorphous precursors, nucleation, crystallization, chiral resolution, nanocrystal assembly, polymorph, and thus morpholog...

Hip fractures are intensely painful, so post‐operative analgesia is an integral part of patient care for early rehabilitation and mobility.[1] Local anaesthetics with epidural additives ideally should provide stable haemodynamics and prolonged analgesia. There is limited literature comparing dexmedetomidine and ketamine as epidural additives. We conducted a study of continuous epidural infusion...

A series of sebacic acid esters containing mercaptobenzothiazole and dialkylenedithiocarbamate, which are potential environmentally friendly lubricating grease additives, were synthesized. The tribological properties as lubricating additives in Li-soap greases were evaluated using a 4-ball tester and SRV tester. The results show that the series of sebasic acid esters with dioctyldithiocarbamate...
