The effect of integrated use of mineral and organic N sources (farmyard manure, poultry manure, and Filter Cake) on yield and N uptake of wheat were assessed in biennial field experiment carried out on silty clay loam soil ...

یک روش سازگاری با محیط  برای سنتز آمیدها توسط N فرمیلاسیون از آمین با فرمیک اسید در حضور نانو اکسید سریم به عنوان یک کاتالیزور موثر و قابل بازیافت تحت تابش  UVاست. واکنش سیستم قابل ملاحظه بوده و هم­چنین به­خاطر روش ساده ...

Let $R$ be a commutative ring with identity,  let $ I $ be a proper ideal of $ R $, and let  $ n ge 1 $ be a positive integer. In this paper, we introduce a class of ideals that is closely related to the class of $I$-prime ...

We generalize the notion of Jacobson graphs into $n$-array columns called $n$-array Jacobson graphs and determine their connectivities and diameters. Also, we will study forbidden structures of these graphs and determine ...

We describe under various conditions abelian subgroups of the automorphism‎ ‎group $mathrm{Aut}(T_{n})$ of the regular $n$-ary tree $T_{n}$‎, ‎which are‎ ‎normalized by the $n$-ary adding machine $tau =(e‎, ‎dots‎, ‎e,tau ...

Let $R$ be a ring‎, ‎and let $n‎, ‎d$ be non-negative integers‎. ‎A right $R$-module $M$ is called $(n‎, ‎d)$-projective if $Ext^{d+1}_R(M‎, ‎A)=0$ for every $n$-copresented right $R$-module $A$‎. ‎$R$ is called right ...

For a real normed space $X$, we study the $n$-dual space of $left( X,leftVert cdot rightVert right) $ and show that the space is a Banach space. Meanwhile, for a real normed space $X$ of dimension $dgeq n$ which satisfies ...

In this paper, we define a new concept of factorization for a bounded bilinear mapping $f:Xtimes Yto Z$, depended on  a natural number $n$ and a cardinal number $kappa$; which is called $n$-factorization property of level ...

Let $nin mathbb{N}$. An additive map $h:Ato B$ between algebras $A$ and $B$ is called $n$-Jordan homomorphism if $h(a^n)=(h(a))^n$ for all $ain A$. We show that every $n$-Jordan homomorphism between commutative Banach ...

In contemporary research, “Heterostructure" assemblies play an important role in energy conversion systems, wherein the composite assemblies facilitate faster charge carrier transport across the material interfaces. ...

Given a set  of  points in the plane and a constant ,-center problem is to find two closed disks which each covers the whole , the diameter of the bigger one is minimized, and the distance of the two centers is at least . ...

N,N,N',N'-tetramethyl-N,N'-bis(sulfo)ethane-1,2-diaminium mesylate ‎‎([TMBSED][Oms]2) is ‎used as a highly efficient and dual-functional catalyst for ...

In this work, N,N,N',N'-tetramethylethylene-diaminium-N,N'-disulfonic acid chloride {[TMEDSA][Cl]2} has been utilized as a highly effective catalyst in order ...

An extremely facile and efficient procedure which has been developed for the synthesis of dihydropyrrol-2-ones. One-pot four-component reaction of amines, dialkyl acetylenedicarboxylates and formaldehyde in the presence ...

An organosuperbase (N,N-dimethylbiguanide) immobilized on mesoporous and magnetically separable silica supports, was found for the first time, to act as a highly-stable, scalable and efficient heterogeneous catalyst for ...

N-(2-Pyridylmethyl)-L-histidine functionalized Fe3O4 magnetic nanoparticles (PMHis@Fe3O4 MNPs) efficiently catalyzed three-component Mannich-type reaction of ketones, aromatic aldehydes and anilines, to synthesize β-amino ...

A new series of N-(5-Mercapto-1,3,4-thiadiazol-2-yl)-2-phenylacetamide derivatives (3a-3j) were synthesized via an amidation reaction using EDC and HOBt in acetonitrile solvent at room temperature condition. Chemical ...

In this work, the first, intense and efficient POCL arising from the reaction of bis (2, 4, 6-trichlrophenyl) oxalate (TCPO) with hydrogen peroxide in the presence of N-[4-(dimethyl ...
