The Political Thought of the Late H.H. Sheikh Zayed Bin Sultan Al Nahyan, Founder of the United Arab Emirates (1966 - 2004)
No full textThis thesis highlights the political thought of H.H. Sheikh Zayed Bin Sultan Al Nahyan, a man who made decisive contributions to the history of the twentieth century, and the various reflections of this political thought on the UAE, its people and the international community at large. In this regard, it explores and analyzes a multifaceted political thought that took its form in political practice in the establishment of the Federation, the management of crises and in the building of a prosperous enduring nation. Evaluating the factors that influenced the formation of the doctrinal matrix of Sheikh Zayed Bin Sultan Al Nahyan, this thesis traces the background from within which Sheikh Zayed’s leadership skills evolved and developed. From his early years onwards, Sheikh Zayed made a firm commitment to undertake the considerable task of building a fully fledged state out of a divided tribal background, improve the lives of citizens, and carve a place for the UAE in the international arena.
This research project illustrates the implications and dimensions of Sheikh Zayed's political thinking process exemplified in his discursive statements and actions. It documents and analyzes the career achievements of Sheikh Zayed, a statesman acknowledged by contemporary and future generations to have had significant impact on the political direction and overall development of the UAE. This impact also demonstrates the potential of his contribution to the field of political thought.
One of this study’s primary conclusions is that the accomplishments of Sheikh Zayed Bin Sultan Al-Nahyan during his rule have resulted primarily from his development of an integrated doctrine of governance that reflected his humanistic outlook. In this regard, at both the domestic and international levels, Sheikh Zayed’s political decisions and acts were undertaken with reference to this outlook
Impaired activity of alpha-ketoglutarate dehydrogenase of heart mitochondria in chronic renal failure: Role of secondary hyperparathyroidism
No full textChronic renal failure (CRF) is associated with impaired oxidation of α-ketoglutarate (α-KG) by heart mitochondria, and previous data indicated that this derangement is due to the state of secondary hyperparathyroidism of CRF. A reduction in the utilization of α-KG by heart mitochondria implies that the activity of mitochondrial α-ketoglutarate dehydrogenase (α-KGDH) is impaired; however, direct evidence for such an abnormality is not available. We examined the V(max) and the K(m) of α-KGHD of heart mitochondria obtained from normal rats, CRF animals and normocalcemic parathyroidectomized (PTX) CRF rats. Our data showed that CRF has no effect on the K(m) of α-KGDH for α-KG. However, V(max) of the enzyme was significantly (p < 0.01) reduced and this abnormality was prevented by PTX of CRF rats. Our results provide the evidence that the impaired utilization of α-KG by myocardial mitochondria of CRF rats is due to reduced V(max) of α-KGDH and that both derangements are mediated by excess PTH or a metabolic consequence of the secondary hyperparathyroidism of CRF
Identification and evaluation of bioflocculant from Bacillus salmalaya 139SI for its application in wastewater treatment / Zayed M. M. Abu Tawila
No full textBioflocculants are flocculating compounds produced by microorganisms during their growth and has recently received extensive consideration from researchers due to their biodegradable, non-toxicity and lack of secondary pollution from degradation intermediates characteristics. The production, optimization, and Characterisation of bioflocculant QZ-7 produced by a novel Bacillus salmalaya strain 139SI which was isolated from a private farm soil in Selangor, Malaysia, were determined. Meanwhile, the optimal culture condition for bioflocculant production was achieved after cultivation at 35.5 °C for 72 h at pH 7, with an inoculum size of 5% (v/v) and sucrose, glucose as carbon source and yeast extract, urea as nitrogen sources. A bioflocculant yield of 2.72 g was recovered from 1 L of broth culture, with maximum flocculating activity that was found to be 92.6%. Chemical analysis revealed that the pure bioflocculant QZ-7 consisted of 79.08% carbohydrates and 15.68% proteins. Infrared spectrometry analysis showed the presence of carboxyl (COO-), hydroxyl (-OH), and amino (-NH3) groups, which are typically from polysaccharides and proteins. The NMR spectroscopy analysis confirmed the result of FTIR, through the presence of functional groups of the QZ-7. Scanning electron microscopy (SEM) analysis showed that QZ-7 exhibited a clear crystalline brick-shaped structure. The average molecular weight of the bioflocculant QZ-7 was calculated to be 5.13×105Da. LC-MS analysis confirmed that QZ-7 was a glycoprotein compound detected at 741m/z–745m/z. Moreover, the presence of glucose at 182.96 m/z, rhamnose at 354.3m/z, and glucuronic acid at 212.8 m/z. SEM- EDX analysis indicated the existence of C, O, N, P and S in this macromolecule as 55.74%, 42.74%, 0.54%, 0.93% iv
and 0.06%, respectively. Thermogravimetric analysis (TGA) of the bioflocculant QZ-7 contained thermos-stable and thermo-labile molecules. Bioflocculant QZ-7 exhibited wide pH stability that ranged from 4 to 7, with a flocculation activity of more than 70%. In addition, QZ-7 was thermally stable and retained more than 80% of its flocculating efficiency after being heated at 60 °C for 30 min. The highest bioflocculating activity of 93.6% was obtained for Ca+2 at 2 mg/L of QZ-7 concentration at pH 7. The treatment of river water by purified bioflocculant QZ-7 showed high performance in the removal of turbidity, total suspended solids and COD. After treating the wastewater, the bioflocculant QZ-7 showed significant flocculating performance with a COD removal efficiency of 93%, whereas a BOD removal efficiency of 92.4% was observed in the B. salmalaya strain 139SI. In addition, results for the removal of heavy metals from industrial wastewater revealed that the bioflocculant QZ-7 was capable of removing the heavy metals. For example, the maximum adsorption of As (89.8 %), and Zn+2 (77.4 %), and Cu+2 (58.4%). Moreover, the bioflocculant QZ-7 had significant removal efficiency of different pharmaceutical compounds, such as Simvastatin (92.45%), Salbutamol (88.69%), Acetaminophen (69%), and Caffeine (66.52%). Furthermore, B. salmalaya 139SI strain and pure bioflocculant QZ-7 could synthesise AgNPs. Also, an antibacterial activity of the AgNPs was detected against test bacterial strains, such as Escherichia coli ATCC35401, Salmonella enteritidis ATCCBAA-711, Staphylococcus aureus ATCC2592 and Pseudomonas aeruginosa, as application of AgNPs
Pimpinella anisum essential oil nanoemulsions against Tribolium castaneum - Insecticidal activity and mode of action
No full textThe red flour beetle, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), is an economically important pest of stored products. As possible alternative to conventional insecticides for its management, plant essential oils have gained interest owing to their effectiveness and eco-friendly features. However, they also show some drawbacks such as low stability, poor water solubility and diffusion, and limited persistence in the environment. A good strategy to overcome these disadvantages is represented by green nanotechnologies. Herein, we developed a nanoemulsion based on the essential oil from Pimpinella anisum L. (Apiaceae) containing 81.2% of (E)-anethole and evaluated its toxicity on T. castaneum adults and F1 progeny, as well as its morphological and histological impact. The anise oil nanoemulsion was characterized by the formation of a semi-solid interphase between oil and water, mean drop size was 198.9 nm, PDI was 0.303, zeta potential was -25.4±4.47 mV and conductivity was 0.029 mS/cm. The nanoemulsion showed toxicity on T. castaneum (LC50=9.3% v/v), with a significant impact on its progeny. Histological damages triggered by feeding and exposure to the anise nanoemulsion were also analyzed by scan electron microscopy (SEM). Overall, our findings showed that the development of nanoemulsions allows to improve the stability of P. anisum essential oil enhancing its efficacy against stored grain pests and contributing to reduce the use of harmful synthetic insecticides

Observations on the basic (G′/G)-expansion method for finding solutions to nonlinear evolution equations
No full textThe extended tanh-function expansion method for finding solutions to nonlinear evolution equations delivers solutions in a straightforward manner and in a neat and helpful form. On the other hand, the more recent but less efficient (G′/G)-expansion method delivers solutions in a rather cumbersome form. It is shown that these solutions are merely disguised forms of the solutions given by the earlier method so that the two methods are entirely equivalent. An unfortunate consequence of this observation is that, in many papers in which the (G′/G)-expansion method has been used, claims that 'new' solutions have been derived are often erroneous; the so-called 'new' solutions are merely disguised versions of previously known solutions

The M&G Drive
No full textabstract: The M&G Drive is a proposed venture project lead by Barrett seniors, Elijah Smith and Jenna Fitzgerald. This project aims to educate Arizona State University (ASU) students on the issues of food insecurity around the Phoenix valley and facilitate their involvement in helping alleviate this pressing social matter. Scientific research has shown significant inverse relationships between food insecurity and the following: mental and physical health, social skills, and academic achievement. As the largest public university in the nation, Arizona State holds a self-ascribed responsibility for the health of its communities. In order to address this issue on behalf of Arizona State and from the standpoint of college students, this proposed venture will encourage the ASU student population to reallocate their unused M&G Dollars (ASU’s on-campus currency) to go toward this cause. Rather than being absorbed back by the university system, unused M&G Dollars can instead be used to purchase non-perishables that will then be donated to the local Phoenix community in order to help fight against food insecurity
Lah–Ribarič type inequalities for (h, g; m)-convex functions
No full textRecently introduced new class of (h, g; m)-convex functions unifies a certain range of convexity, thus allowing the generalizations of know results. In this paper we prove Lah–Ribarič type inequalities for (h, g; m)-convex functions from which we obtain inequalities of Hermite–Hadamard, Fejér, Giaccardi, Popoviciu and Petrović. © 2021, The Author(s) under exclusive licence to The Royal Academy of Sciences, Madrid
Representative Bureaucracy and the Willingness to Coproduce: An Experimental Study
No full textRelying on the theory of representative bureaucracy—specifically, the notion of symbolic representation—this article examines whether varying the number of female public officials overseeing a local recycling program influences citizens’ (especially women's) willingness to cooperate with the government by recycling, thus coproducing important policy outcomes. Using a survey experiment in which the first names of public officials are manipulated, the authors find a clear pattern of increasing willingness on the part of women to coproduce when female names are more represented in the agency responsible for recycling, particularly with respect to the more difficult task of composting food waste. Overall, men in the experiment were less willing to coproduce across all measures and less responsive to the gender balance of names. These findings have important implications for the theory of representative bureaucracy and for efforts to promote the coproduction of public services.This is the peer reviewed version of the following article: Riccucci, Norma M., Van Ryzin, Gregg G. & Li, Huafang.
