Some applications of D α-closed sets in topological spaces
Publication date: March 2016 Source:Egyptian Journal of Basic and Applied Sciences, Volume 3, Issue 1 Author(s): O.R. Sayed, A.M. Khalil In this paper, a new kind of sets called Dα-open sets are introduced and studied in a topological spaces. The class of all Dα-open sets is strictly between the class of all α-open sets and g-open sets. Also, as applications we introduce and study Dα-continuous, Dα-open, and Dα-closed functions between topological spaces. Finally, some properties of Dα-closed and strongly Dα-closed graphs are investigated. (Source: Egyptian Journal of Basic and Applied Sciences)

Consumption of high sucrose and/or high salt diet alters sperm function in male Sprague –Dawley rats
Publication date: June 2016 Source:Egyptian Journal of Basic and Applied Sciences, Volume 3, Issue 2 Author(s): D.A. Adekunbi, O.A. Ogunsola, O.T. Oyelowo, E.O. Aluko, A.A. Popoola, O.O. Akinboboye Diets laden with salt and refined sugar have been implicated in the pathogenesis of diabetes and hypertension. However, few studies have investigated the impact of such diets on reproductive functions, hence, the present study. Male Sprague–Dawley rats (100–120 g, n = 24) were randomly divided into four groups designated control (standard chow), sucrose (30% w/v as drinking water), salt (8% salt diet) a...

A graph theoretic model for prediction of reticulation events and phylogenetic networks for DNA sequences
In this study, a phylogenetic network construction model based on basic graph theory concepts is reported. This model finds the distance matrix of every sequence considered in the study. The two features (positioning and stack interactions) of every DNA sequence and their combined effect have been taken into account to calculate the distances. Results suggested that reticulate events can be observed by using the distances obtained by the proposed method and no such event is predicted by using the distances calculated by the previous method. The important results obtained in the form of distances are 1.637300, 2.000000, 0.9...

Biosorption of toxic heavy metals from aqueous solution by Ulva lactuca activated carbon
In this study, the batch adsorption of toxic Cu+2, Cr+3, Cd+2 and Pb+2 ions using marine macroalga Ulva lactuca (AP) and its activated carbon (AAC) were examined. The adsorption mechanism of heavy metal ions on AP and AAC was studied using various analytical techniques. The effect of several parameters such as contact time, algal dose, effect of pH, and initial concentration of metal ions on the adsorption process was estimated. The optimum adsorption was found to occur at pH 5.0, contact time 60 min, adsorbent dose 0.8 g/L, and initial concentration 60 mg/L. The maximum removal efficiency values of AP and AAC for he...

Effects of two weeks of administration of Ocimum Gratissimum leaf on feeding pattern and markers of renal function in rats treated with gentamicin
This study investigated the effects of aqueous extract of Ocimum gratissimum leaf (AOGL) on some markers of renal function in rats with gentamicin-induced nephropathy. Thirty adult male Wistar rats were used for this study. They were divided into 5 groups as follows: Group 1 (the control) (n = 5) received distilled water daily by oral route for the whole period of the study. Group 2 (the toxic control) (n = 10) received 100 mg/kg/day of gentamicin i.p. for a week. Groups 3, 4, and 5 (n = 5) were pre-treated with gentamicin as the Group 2 rats, after which they received 100, 200 and 400 mg/kg/day each of AOG...

Advancing role of melatonin in the treatment of neuropsychiatric disorders
In conclusion, the gathering body of evidence both from preclinical and clinical literatures suggests strong antioxidant activities and diverse pleiotropic mechanisms of melatonin for potential neuroprotective role in diverse neuropsychiatric disorders. However, there is still a lack of melatonergic ligands with high selectivity and specificity to precisely target any particular neuropsychiatric disorders for which limited therapeutic options are currently available clinically.

Simulations of an all-optical flip-flop with a reset pulse frequency exceeding operating frequency
Publication date: Available online 10 May 2016 Source:Egyptian Journal of Basic and Applied Sciences Author(s): Hossam Zoweil An all-optical flip-flop based on a nonlinear multi-section DFB semiconductor laser structure is proposed. Holding beam is not required for device's operation. A section of the DFB structure is detuned to prevent lasing in the “OFF” state, and it is accompanied with a negative nonlinear coefficient that is due to partial absorption of photons at Urbach tail. At a high light intensity in the structure the nonlinear coefficient reduces the detuning, and the device is in lasing state; “ON�...
