Impact of Surface Water and Groundwater Pollutions on Irrigated Soil, El Minia Province, Northern Upper Egypt  [PDF]
Rafat Zaki, Esam A. Ismail, Wagih S. Mohamed, Ali Kamel Ali
Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.717120
Abstract: Current research has been focused on heavy metals pollution in surface water and groundwater and effect on irrigated soil from El Minia Province, north Upper Egypt. Concentration of heavy metals (e.g., As, Co, Hg, Ni, Se, Cd and Cr) in surface water, groundwater and irrigated soil samples is most significantly affected by leachate of many pollutants as the factories, agricultural activities, urban and natural processes. Microbiological parameters and microscopic investigations are revealed that some localities are common by micro-organisms, which are unsuitable for drinking waters.

Rhinolith: Delayed Presentation after Head Trauma—A Case Report
Ali S. Al Mastour,Wagih M. Ghnnam,Abdu H. Zubaidi
Case Reports in Otolaryngology , 2012, DOI: 10.1155/2012/492081
Abstract: Rhinoliths are uncommon clinical entities reported in clinical practice as unusual cause of unilateral nasal obstruction and foul smell nasal discharge. Rhinolith is calcified material found in the nasal cavity incidentally or due to patient complaint. It should be suspected when patient presents with nasal symptoms and found to have stony mass showed radiologically. We reported a 28-year-old Saudi male with left sided (LT) nasal obstruction and foul smell discharge for 5 years suspected as being due to foreign body presence since childhood due to head trauma following car accident in sandy area. 1. Introduction Rhinoliths are calcified material around intranasal foreign body. They can be endogenous if occur around body tissues as tooth or exogenous if they occur around foreign subject as stones, cotton, or beads. They are found usually in anterior nasal cavity commonly associated with narrowing due to deviated septum, spurs, and/or turbinate hypertrophy. Endoscopic appearance is the main step in diagnosis which can be supported by radiology. Complete resolution of symptoms occurs after endoscopic surgical removal [1–3]. 2. Case History A 28-year-old Saudi male presented to ORL HNS clinic referred from another hospital for his complaint of left (LT) nasal obstruction and foul smell discharge for five years. Symptoms were progressively noticed and disturb the patient’s life in the last 3 years. He received multiple courses of antibiotics and nasal steroids with no benefit. He had no history of foreign body introduced into nasal cavity. He had history of head trauma after car accident at childhood in sandy area. Anterior rhinoscopy showed irregular hard material with crustations and thick secretions around, stuck between septal spur and inferior turbinate at LT anterior nasal cavity (Figure 1). Trials of removal in clinic failed causing epistaxis. Plain X-ray and CT scan showed dense irregular material at LT nasal cavity occupying floor without extension outside nasal cavity (Figure 2). Rhinolith was suspected then endoscopic removal done anteriorly after rhinolith was divided in two pieces and bleeding controlled (Figures 3 and 4). Then antibiotic ointment was applied in the place and patient given oral augmentin 625?mg three times daily along with nasal decongestant and analgesia for one week. Patient came to the clinic after one week later in better condition with dramatic improvement and resolution of symptoms.

Abstract: Purpose: Compare the effectiveness of Phototherapeutic keratectomy (PTK) in treatment corneal dystrophies versus superficial corneal scars: visual outcomes, recurrence rate and safety profile. Methods: PTK was performed in 51 eyes of 51 patients. Data regarding the indications for PTK, ablation depth, symptomatic relief, pre-and postoperative best spectacle-corrected visual acuity (BSCVA), spherical equivalent changes, recurrence and complications were analyzed. The indications for PTK in our study were classified into two categories – group A: patients with corneal dystrophies (n = 23) and the other group B (n = 28) with other indications. Results: The average age of the patients was 47 years (±16.4). The mean follow up period was 15.16 months (±10.01 months). Post operatively, there were no significant complications. While the overall BSCVA in the patients improved from 20/41 (0.484) to 20/32 (0.645), group A showed improvement from 20/35 (0.561) to 20/29 (0.687), as compared to group B in which BSCVA improved from 20/47 (0.421) to 20/33 (0.611). The most common indication in group A was granular corneal dystrophy (n = 10) and the most common indication in group B was post traumatic/infectious corneal scar or opacity (n = 10). Eighty-six percent (n = 44) of all patients had alleviation of symptoms. Recurrence of symptoms was seen in 3 eyes of recurrent corneal erosions which required retreatment. Conclusion: PTK is a safe and effective procedure. The outcome of this study suggests that PTK improves BSCVA. PTK appears to improve ocular surface health. Furthermore, PTK can be recommended to most patients with corneal dystrophies as a treatment modality prior to other more invasive procedure (viz. penetrating keratoplasty).

Quantum Entanglement as a Consequence of a Cantorian Micro Spacetime Geometry  [PDF]
Mohamed S. El Naschie
Journal of Quantum Information Science (JQIS) , 2011, DOI: 10.4236/jqis.2011.12007
Abstract: Building upon the pioneering work of J. Bell [1] and an incredible result due to L. Hardy [2] it was shown that the probability of quantum entanglement of two particles is a maximum of 9.0169945 percent [2]. This happens to be exactly the golden mean to the power of five (?5) [3-7]. Although it has gone largely unnoticed for a long time, this result was essentially established independently in a much wider context by the present author almost two decades ago [3-6]. The present work gives two fundamentally different derivations of Hardy’s beautiful result leading to precisely the same general conclusion, namely that by virtue of the zero measure of the underlying Cantorian-fractal spacetime geometry the notion of spatial separability in quantum physics is devoid of any meaning [7]. The first derivation is purely logical and uses a probability theory which combines the discrete with the continuum. The second derivation is purely geometrical and topological using the fundamental equations of a theory developed by the author and his collaborators frequently referred to as E-infinity or Cantorian spacetime theory [3-7].
The Analytical and Numerical Solutions of Differential Equations Describing of an Inclined Cable Subjected to External and Parametric Excitation Forces  [PDF]
Mohamed S. Abd Elkader
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.212209
Abstract: The analytical and numerical solutions of the response of an inclined cable subjected to external and parametric excitation forces is studied. The method of perturbation technique are applied to obtained the periodic response equation near the simultaneous principal parametric resonance in the presence of 2:1 internal resonance of the system. All different resonance cases are extracted. The effects of different parameters and worst resonance case on the vibrating system are investigated. The stability of the system are studied by using frequency response equations and phase-plane method. Variation of the parameters α2, α3, β2, γ2, η2, γ3, η3, f2 leads to multi-valued amplitudes and hence to jump phenomena. The simulation results are achieved using MATLAB 7.6 programs.
