Study of phase separation in Ga25Se75-xTex chalcogenide thin films

Progress in Natural Science:Materials International 2013年第2期23卷 139-144页

作者： f.a. Al-Agel E.A. Al-Arfaj f.M. Al-Marzouki Shamshad A. Khan A.A. Al-Ghamdi Department of Physics King Abdulaziz University Department of Physics College of Applied Sciences Umm Al-Qura University Department of Physics St. Andrew's College

The effects of composition and thermal annealing in between glass transition and crystallization temperature on the optical and structural properties of Ga25Se75-xTex were investigated. The glass transition and crystallization temperature of the synthesized samples was measured by non-isothermal DSC measurements. Amorphous thin films of Ga25Se75-xTex glasses were grown onto ultra clean glass/Si wafer (100) substrates using the vacuum evaporation technique. The effect of thermal annealing on the optical gap (Eg) for Ga25Se75-xTex thin films in the temperature range 358-388K is studied. As-prepared and annealed thin films were characterized by X-ray diff.a.tion, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy and optical absorption. Thermal annealing was found to be accompanied by structural effects, which in turn, lead to changes in the optical constants. The optical absorption coefficient (a) for as-deposited and thermally annealed films was calculated from the absorbance data. from the knowledge of.a.sorption coefficient at different wavelengths, the optical band gap (Eg) was calculated for all compositions of Ga25Se75-xTex thin films before and after thermal annealing. Results indicate that allowed indirect optical transition is predominated in as-deposited and thermally annealed thin films. The influence of Te incorporation and thermal annealing in Ga25Se75-xTex thin films results in a gradual decrease in the indirect optical gap, this behaviorcan be explained as increased tailing. The decrease in optical band gap and an increase in absorption coefficient and extinction coefficient with thermal annealing can be attributed to transformation from amorphous to crystalline phase.

Revolution in Emirate System in Nigeria： female Emirs Emerge to Assert Their Existence

引用

International Relations and Diplomacy 2014年第3期2卷 212-226页

作者： f.a. OLASUPO Obafemi Awolowo University Ile-lfe Nigeria

Against anybody＇s expectation, female Emirs are found in Northern parts of Nigeria. After several years of their being buried, specifically since the advent of colonialisms--Arabian, European and Christian types--truths about their existence have begun to emerge not just from the female Emirs themselves but also from their Male counterparts. The journey towards these spectacular discoveries theoretically began in 2003 with exploration of similar female Obas and Obis in the Southern parts of the country. In 2003, the researcher read in the Guardian newspaper of.a.female ruler turbaned at the palace of Emir of Minna. Again, in 2007, Agency f.a.ce Press （AfP） reported the case of this female Emir ＂Though strange it is true. In Kumbwada, a village of.a.out 400 kilometers away from Kano, a woman is the traditional and religious leader. No man dares as any that assumes the throne dies mysteriously within a week＂. This was reported by The Nation Newspaper. ~ In 2010, upon hearing about existence of female Emirs among the Baatonu people of Kwara State, the author commissioned a Master of Science （***.） student to research on this and in fact writes his term paper on it. The researcher then followed up this with pragmatic visit and interview with these female Emirs, first, in Kumbwada, Niger State in 2010, and second, Ilesalbaruba, Gwanara and Okuta in Baruten Local Government area of Kwara State in 2013. The outcome of these practical visits and interview with these female and Male Emirs in the Northern parts of the country is what the researcher intends to share with you in this paper.

NON-ORTHOGONAL P-WAVELET PACKETS ON THE HALf-LINE

引用

Analysis in Theory and Applications 2012年第4期28卷 385-396页

作者： f.a. Shah University of Kashmir

In this paper, the notion of p-wavelet packets on the positive half-line P＋ is introduced. A new method for constructing non-orthogonal wavelet packets related to Walsh functions is developed by splitting the wavelet subspaces directly instead of using the lowpass and high-pass filters associated with the multiresolution analysis as used in the classical theory of wavelet packets. further, the method overcomes the difficulty of constructing non-orthogonal wavelet packets of the dilation factor p 〉 2.

female Traditional Rulers in Eastern Nigeria： Eze-Ogo Alu Ibiam as a Case Study

引用

International Relations and Diplomacy 2015年第2期3卷 116-122页

作者： f.a. OLASUPO Obafemi Awolowo University Ile-lfe Nigeria

Over a period of three years, research activities were embarked upon to verify the claim that female traditional rulers also exist in significant degree in the Eastern part of the country, particularly among the Igbo speaking people The essence of the research was to find out whether there are some correlations between the findings here and those of other parts of Nigeria--Western and Northern part of the country in particular. The paper intends to find out how symmetrical and asymmetrical the finds female traditional rulers are with those of their counterparts in the Western and Northern part of the country.

Auxin as a Model for the Integration of Hormonal Signal Processing and Transduction

Molecular Plant 2008年第2期1卷 229-237页

作者： W.D. Teale f.a. Ditengou A.D. Dovzhenko X. Li A.M. Molendijk B. Ruperti I. Paponov K. Palme Institute of Biology Ⅱ Faculty of Biology University of Freiburg D-79104 Freiburg Germanya Dipartimento di Agronomia Ambientale e Produzioni Vegetali Agripolis University of Padova viale dell'Universita 16 35020 Legnaro Italy

The regulation of plant growth responds to many stimuli. These responses allow environmental adaptation, thereby increasing fitness. In many cases, the relay of information about a plant＇s environment is through plant hormones. These messengers integrate environmental information into developmental pathways to determine plant shape. This re- view will use, as an example, auxin in the root ofArabidopsis thaliana to illustrate the complex nature of hormonal signal processing and transduction. It will then make the case that the application of.a.systems-biology approach is necessary, if the relationship between a plant＇s environment and its growth/developmental responses is to be properly understood.

The effects of background millimeter radiations( BMR) in patients with coronary artery disease( CAD),hypertension and in subjects with Inherited real risk of CAD,were investigated through invariant statistic measures,typical of nonlinear dynamics analysis of biological systems. The experimental evidences show that BMR ameliorate the nonlinear complexity in biosystems,recognized sign of physiological behavior,by increasing both the rate of unpredictability of heart rate variability( HRV) in patients with metabolic syndrome and the f.a.tal dimension of coronary microvessel oscillations in subjects with pre-metabolic syndrome,healing their genetic alteration and CAD Inherited real risk.

＜正＞ "Royal Gala" apple （Malus domestic Borkh） transformation was conducted using radish seed γ-thionin Rs-AfP1 gene and uidA （GUS） gene driven by green specific spinach ribulose bisphosphate carboxylase/oxygenase （ rubisco） activase promoter （RCAPp） and putative transgenic apple plants with NPTII resistance were produced. Southern blot analysis of plants confirmed the integration of thionin and GUS genes into apple genome. GUS assay of both green and etiolated stem confirmed the function of the tissue-specific expression of RCAP promoter. Transgenic apples were transplanted in the field to identify the agronomy traits.

在一个具有吸入/吹出功能、幂律变化的伸展表面上,分析了二维稳定非Newton流体的流动.假定热传导率按温度的线性函数变化.将控制方程无量纲化后,用Runge-Kutta法进行数值求解.将该问题的一个特例所得到的一些结果,与以前发表的结果相比较,发现两者有着很好的一致性.考虑两种情况,一种对应着致冷的表面温度,另一种对应着均匀的表面温度.数值结果显示,对上述两种情况,可变热传导参数β,传质参数d和幂律指数n,对温度分布和Nusselt数有着重大的影响.
