Two field experiments were carried out at the village ten, Abu Humus, El-Beheira Governorate, Egypt, during two successive seasons 2016/2017 and 2017/2018, to evaluate effect of three types herbicide irrigation intervals on productivity quality onion cultivar (Giza Red). The designed as split plot in randomized complete block design with replications. Irrigation – (I1) 20 days, (I2) 30 (I3) 40 ...

We review the results of our work on the iodine interaction with thioamides, selenoamides, and amides. Complexes with (i) “spoke” or “extended spoke” structures, D · I2 and D · I2 · I2, respectively, (D is the ligand donor) (ii) iodonium salts of {[D2 − I][In]} (n = 3, 7) and {[D2 − I][FeCl4]} formulae and (iii) disulfides of the categories (a) [D − D], (b) {[D−DH][I3]} have been isolated and c...

Abstract. If a tensor with various symmetries is properly unfolded, then the resulting matrix inherits those symmetries. As tensor computations become increasingly important it is imperative that we develop efficient structure preserving methods for matrices with multiple symmetries. In this paper we consider how to exploit and preserve structure in the pivoted Cholesky factorization when appro...

The current sanitary crisis due to COVID-19 has further evidenced the enormous digital exclusion of older adults. Furthermore, urged adults adopt new technologies facilitate their tasks, as well provide them with an effective means against loneliness and social isolation caused by confinement. In light this, Digital Literacy is necessary for all those excluded from era, who are characterized ma...

Salts in the liquid phase at room temperature–ionic liquids– have recently received increased attention due to their unique properties.[1] These include high ionic conductivity, high thermal and chemical stability, broad electrochemical windows, non-volatility and non-flammability. These important properties make them versatile alternatives to conventional solvent-based systems, and their poten...

We provide indirect evidence that six axonemal proteins here referred to as "dynein regulatory complex" (drc) are located in close proximity with the inner dynein arms I2 and I3. Subsets of drc subunits are missing from five second-site suppressors, pf2, pf3, suppf3, suppf4, and suppf5, that restore flagellar motility but not radial spoke structure of radial spoke mutants. The absence of drc co...

A mathematical framework that permits the factorization of a joint probability distribution into its localized components for a two-dimensional array of pixels is presented. The factorization was used to estimate the contribution to mutual information of two- (I2) and three-pixel (I3) luminance correlations for a large ensemble of natural images analyzed at various spatial scales and pixel dept...

Time-resolved X-ray solution scattering is sensitive to global molecular structure and can track the dynamics of chemical reactions. In this article, we review our recent studies on triiodide ion (I3 (-)) and molecular iodine (I2) in solution. For I3 (-), we elucidated the excitation wavelength-dependent photochemistry and the solvent-dependent ground-state structure. For I2, by combining time-...
