In this paper we study the stability functions on abelian categories introduced by Rudakov in \cite{Ru} and their relation with torsion classes maximal green sequences. Moreover introduce a new kind of function which is compatible wall chamber category.

Cities worldwide are growing at unprecedented rates, compromising their surrounding landscapes, and consuming many scarce resources [...]

Background: Green tea is a popular type of tea that is made of unfermented tea leaves. Green tea has been used for thousands of years by people in Eastern countries for a variety of health reasons. One of the primary benefits of Green Tea in regard to fertility is not in what it contains, but rather in what it does not contain. Materials and Methods: In the present study attempts to investigate...

polypyrrole is one of the most useful conductive polymers, but green synthesis of this polymer has been restricted until now. the objective of the present paper is green synthesis of nano polypyrrole (ppy) by oxidative polymerization using urea-hydrogen peroxide. it was found that conductivity and morphology of polypyrrole are highly dependent on the reaction conditions such as the molar ratio ...

Epoxides undergo regioselective ring opening with various nucleophiles using catalytic amount of nano magnesium oxide and water as solvent under mild reaction conditions. The remarkable features of this method are improved yields, high regioselectivity, and green chemistry agreement.

friedel–crafts synthesis of triarylmethanes over 3-methyl-1-sulfonicacid imidazolium tetrachloroaluminate under green conditions:in this work, friedel–crafts (fc) alkylation of various arenes with aromatic aldehydes catalyzed by 3-methyl-1-sulfonic acid imidazoliumtetrachloroaluminate {[msim]alcl4}, as a green catalyst, to prepare triarylmethanes (tams) has been carried out. some aromatic aldeh...

in this work, the ionic liquid triethylamine-bonded sulfonic acid {[et3n–so3h]cl}, n,n-diethyl-n-sulfoethanammonium chloride was used as a green acidic homogeneous catalyst to synthesis of 3,4-dihydropyrimidin-2(1h)-ones and 3,4-dihydropyrimidin-2(1h)-thiones as two categories of heterocycles, from aldehyde, dicarbonyl compound and urea or thiourea throughout the one-pot three components cycloc...

Application of green fluorescent protein (GFP) as a molecular biosensor or reporter is limited by several factors especially its poor fluorescence at low pH conditions. There are conflicting data on this limitation, however, systematic studies to assess the importance of this factor for growing bacterial cultures are lacking. In this study, effect of low pH on GFP green and red fluorescence int...

In this work, Nano TiO2@KSF used as an efficient, homogeneous and reusable catalyst for the synthesis of pyrano[2,3-d]-pyrimidinone derivatives via three-component reactions between malononitrile, barbituric acid and various aldehydes in water. The products were formed in high yields within short reaction times. Also, this catalyst can be reused several times without loss of its catalytic activ...
