Given an arbitrary n, we consider anisotropic quadratic forms of dimension n over all fields of characteristic = 2 and prove that the height of an n-dimensional excellent form (depending on n only) is the (precise) lower bound of the heights of all forms of dimension n.

Cucumber is one of the main vegetables in Iranian food basket. A wide range of pesticides are used for crops protection during the cultivation of vegetables such as cucumber due to heavy pest infestation. Analysis of pesticide residues in food and other environmental commodities have become essential requirement for consumers, producers, and food quality control authorities. This study was aime...

In this manuscript novel architectures for modulo 2 þ 1 multi-operand addition and residue generation are introduced. The proposed arithmetic components consist of a translation stage, an inverted endaround-carry carry-save-adder tree and an enhanced diminished-1 modulo 2 þ 1 adder. Qualitative and quantitative results indicate that the proposed architectures result in significantly faster and ...

a trial study was carried out to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on wheat yield and components, at the agricultural faculty of shahidchamran university of ahvaz during 2011-2012.the experimental design was splitplot at randomized completed block design arrangement. the main plot were different wheat residue manage...

Interaction with the solvent plays a critical role in modulating the structure and dynamics of a protein. Because of the heterogeneity of the interaction strength, it is difficult to identify multi-scale structural response. Using a coarse-grained Monte Carlo approach, we study the structure and dynamics of a protein (H3.1) in effective solvent media. The structural response is examined as a fu...

We use cell decomposition techniques to study additive reducts of p-adic fields. We consider a very general class of fields, including fields with infinite residue fields, which we study using a multi-sorted language. The results are used to obtain cell decomposition results for the case of finite residue fields. We do not require fields to be Henselian, and we allow them to be of any character...

background: tetracyclines (tcs) are broad-spectrumantibiotics that are widely used in veterinary medicine. thepresence of tcs residues in milk is a public health concern allover the world. objectives:this study aimed to determine tcsresiduals in pasteurized milk marketed by some dairy companiesin tehran from april 2011 to march 2012. methods: 432pasteurized milk samples were purchased from supe...

Dr. Hans Mol is senior scientist at RIKILTWageningen UR Introduction Regulatory authorities throughout the world set and enforce strict limits on the maximum residue levels (MRLs or tolerances) of pesticides permitted on food and feeds. It falls to analytical laboratories to test these products and ensure they meet the relevant standards. The analytical challenge is to look for over 1,500 poten...
