A pressure dependent Schrodinger equation is used to find the conditions that lead to superconductivity. When no pressure is exerted, the superconductor resistance vanishes beyond a critical temperature related to the repulsive force potential of the electron gass, where one assuming the electron total energy to be thermal, where applying mechanical pressure destroys Sc when it exceeds a certain critical value. However when the electron total energy is an assumed to be that of the free electron model and that the pressure is thermal and mechanical, the situation is different. The quantum expression for resistance shows that the increase of mechanical pressure increases the critical temperature. Such phenomenon is observed in high temperature cupper group.

Passive RFID Tag for Railway Application

引用

Open Journal of Antennas and Propagation 2018年第2期6卷 15-24页

作者： Shreine abd El-Rahman ahmed Attiya Hossam El-Deen Mamoud Hala abd-El Kader Electronics Research Institute Giza Egypt Shoubra Faculty of Engineering Benha University Cairo Egypt

Passive RFID tags based on narrow band absorbers are proposed for railway applications. The tags consist of absorbing tiles of size 30 × 30 cm2. The de-signs of these narrow band absorbers are presented based on infinite array approximation by using periodic boundary conditions. Then, the radar cross sections (RCS) of finite tiles of these designed absorbers are compared with the corresponding RCS of a conduction plate of the same size of the tiles. The difference between the RCS of the absorbing tiles and the conducting tiles corresponds to the RFID digit “1” or “0”. An experiential verification for a sample of these narrow band absorbers is presented based on measuring a fi-nite tile inside a transverse electromagnetic (TEM) cell. The design of this TEM cell is also discussed in detail.

Homes or Just Houses: The Housing Needs of Female-Headed Households in Egypt

引用

Journal of Building Construction and Planning Research 2018年第3期6卷 138-150页

作者： Reem Hamad ahmed S. abd Elrahman Ayat Ismail Department of Urban Planning and Design Faculty of Engineering Ain Shams University Cairo Egypt

With the drastic rise in divorce rates in Egypt in the last few decades, targeting female-headed households as new housing segment is becoming increasingly crucial. Female-headed households are categorized as part of the housing vulnerable groups supported by the government. The housing needs, preferences and the market navigation patterns of this group are the study matter of this paper. While this group shares similarities in the housing needs with the two-parent families there are defined differences in the housing presences and market navigation patterns of the two groups. The paper also sheds the light on how the social characteristics of the female-headed households determine the housing problems they face with the current market offerings. Then, it outlines a typology of the housing preferred by the female heads, with the aim of generating recommendations that would help create more inclusive and satisfactory housing market offerings tailored for them. The proximity of the workplace to the housing unit in addition to the presence of an active community center within the neighborhoods was on top of their housing demands.

Lumbar Disc Herniation in Pediatric

引用

Open Journal of Modern Neurosurgery 2018年第2期8卷 233-238页

作者： Mostafa abd Elsamea Mohamed Shaban ahmed Taha Samer Elshora Neurosurgery Orthopedic Department Faculty of Medicine (Damietta) Al-Azhar University Egypt

Lumbar disc herniation is a common complaint among adults with degenerated lumbar intervertebral discs, however its incidence in childhood and adolescence is abundant. Findings recommended that pediatric lumbar disc herniation is dissimilar in numerous way from that in adults. It was confirmed that pediatric patients respond to conventional management less than adults, also the consequence of the operation continued to be acceptable for at least 10 years after the first surgery even though it seems to decline somewhat. This retrospective study was undertaken to determine the clinical outcome and the feature of lumbar disc prolapse in pediatric patients. 12 patients younger than 18 years were operated for lumbar disc prolapse in the period from 2012-2016. Patients preoperative data and radiological imaging, operative and postoperative follow up were reviewed. 12 patients were included in this study, 10 were male and 2 females, the average age was 15 years (ranging between 12 - 18 years). The average duration of the symptoms was 11 months. The average follow up was 14 months. All patients had a sciatica prior to surgery, 35% had motor deficit, and 60% had parasthesia. Conservative treatment failed in all patients. After surgery and follow up, improvement occurs in about 80% of patients, ranging from excellent to good, and 20% of patients with fair outcome. According to Pain Visual Analogue Scale, leg pain reduced from 90 - 30 and back pain from 80 - 35. Conclusion: Pediatric lumbar disc herniation is an uncommon object leading to hospitalization. About 0.1% - 0.2% of children and adolescence surgery for lumbar disc herniation in pediatric does not lead to chronic back pain or interfere with physical activity and is related to the excellent short consequence.

Correlation between Left Ventricular End Diastolic Pressure and Torsion Dynamics in Patients with Diastolic Dysfunction, Speckle Tracking Imaging Study

引用

World Journal of Cardiovascular Diseases 2019年第2期9卷 81-91页

作者： ahmed Emara Mahmoud Kamel Said Shalaby Wesam El Shafay ahmed abd El-Razzak Department of Cardiology Menoufia University Menoufia City Egypt

Background: Invasive measuring of LV end diastolic pressure (LVEDP) provides reliable assessment of LV diastolic dysfunction, but its invasive nature limits its use in daily practice. Accurate noninvasive assessment of LV diastolic dysfunction is highly desirable, and the relationship between the degree of LVEDP and LV torsion dynamics assessed by 2D speckle tracking is not clearly assessed;here in our study we aimed to assess the relation between the degree of LVEDP and torsion dynamics of left ventricle. Methods: The study included sixty patients divided equally into 3 groups according to the degree of LVEDP, group I: mmHg, group II: 12 - 18 mmHg, and group III: >18 mmHg;complete conventional echo-Doppler study includes also annular septal E wave peak velocity, E/E’ ratio and 2D-speckle tracking including parameters of LV global longitudinal strain (GLS), peak and time to peak of twist ratio (TR & TT respectively), peak and time to peak of untwist ratio (UTR & UTT respectively). Results: There was significant progressive decrease in GLS with progressive increase in LVEDP from I to III. Untwist ratio increased in group II and decreased in significant degree in group III;Twist ratio did not differ with different grades of LVEDP. LA diameter and E/E’ increase from group I to III. The LVEDP is negatively correlated with the UTR and GLS is positively correlated with UTT, E/E & LA diameter. The E/E’ ratio is correlated negatively with the UTR, GLS and positively with LVEDP & UTT and LA diameter. Conclusions: Noninvasive assessment of LV torsion and untwisting was feasible in patients with various grades of LVEDP and diastolic dysfunction;the peak untwist ratio increased in mild degree of increased LVEDP then decreased again with more increase in LVEDP;LVEDP wasnegatively correlated with the peak untwist ratio and GLS was positively correlated with UTT and E/E’.

The construction and performance characteristics of a novel Iron(III) membrane sensor based on (37-bis-[(diethoxy-thiophosphoryl)-oxy]-5,11,17,23,29,35-hexa-kis-(1,1-dimethylethyl)-calix[6]-arene-38,39,40,41,42-pentol) (A) were reported in this paper. The sensor was prepared by incorporating compound (A) into a plasticized polyvinyl chloride PVC membrane. The electrode reveals a Nernstian behavior over a wide iron ion concentration range (1.0 × 10-2 - 1.0 × 10-4 mol·L-1), and relatively low detection limit (1.0 × 10-5 mol·L-1). The potentiometric response was independent on the pH of the solution in the range of 4 - 7. The electrode showed a very short response time (<5 s). It exhibited very good selectivity relative to a wide variety of metal cations. Correlation of selectivity coefficient values with ionic radii of interferent cations was discussed. The proposed iron- ISE was applied for analysis of iron containing samples with comparison to a recommended spectrophotometric method.
