Effects of Hypothermia on Renal Functions for Patients undergo Coronary Artery Bypass Graft Surgery
...Show More Authors

Objective: To determine the effectiveness of hypothermia on renal functions for patients undergoing
coronary artery bypass graft CABG surgery.
Methodology: A purposive (non-probability) sample of (50) patients undergoing Isolated coronary artery
bypass graft surgery consecutively admitted to the surgical ward, and they were followed up in the
intraoperative, Intensive Care Unit (ICU) and in the postoperative (surgical ward). Post-operative renal function
test (glumeruler filteration rate (GFR) by using the Crockroft-Gault formula and serum creatinine level) was
determined first week post operative and post operative renal function was classified on the base of peak of
the serum creatinine level and decline of glomeruler filteration rate(GFR) as following : normal renal function
serum creatinine concentration and decline in(GFR) less than 25% from preoperative, moderate renal
dysfunction increase serum creatinine concentration and decline in(GFR) 25%-50% from preoperative, sever
renal dysfunction increase serum creatinine concentration and decline in(GFR) more than 50% from
preoperative test.
Results: results of this study show that (78%) from the sample develop post operative renal dysfunction and
the highly percentage of them are male (50%), advance age 60-70 (60%), smoking (47.0%), diabetes mellitus
DM (68%), cardiopulmonary bypass 180 and more (57.20%), New York Heart Association calcification NYHA
class III(47.5%) and patient without Intra Aortic Balloon Pump IABP(50,0%) . We conclude from the study that
highly percentage of patient undergoing isolated CABG may develop postoperative renal dysfunction even
when using hypothermic strategy as a protective measure and the patients with DM, male, advance age,
smoker, prolong time of CPB (more than 180 minutes), NYHA class III and patient without IABP are considered
as patient at high risk to develop postoperative renal dysfunction.
Recommendations: The researcher recommended that to find addition strategy rather than hypothermia
to protect renal function especially with the high risk patients during isolated CABG surgery.

Cubic intuitionistic ideals of a TM-algebra
...Show More Authors

This study investigated the cubic intuitionistic fuzzy set of TM-algebra as a generalization of the cubic set. First, a cubic intuitionistic ideal and a cubic intuitionistic T-ideal are defined, followed by a discussion of their properties. Furthermore, the level set of a cubic intuitionistic TM-algebra is defined, and the relationship between a cubic intuitionistic level set and the cubic intuitionistic T-ideal is established. A novel definition of a cubic intuitionistic set under homomorphism is proposed, and several significant results are demonstrated.

GENERATION OF MPSK SIGNAL USING LOGIC CIRCUITS
...Show More Authors

The traditional technique of generating MPSK signals is basically to use IQ modulator that involves analog processing like multiplication and addition where inaccuracies may exist and would lead to imbalance problems that affects the output modulated signal and hence the overall performance of the system. In this paper, a simple method is presented for generating the MPSK using logic circuits that basically generated M-carrier signals each carrier of different equally spaced phase shift. Then these carriers are time multiplexed, according to the data symbols, into the output modulated signal.

Thermo-mechanical properties of cubic lanthanide oxides
...Show More Authors

This contribution investigates the effect of the addition of the Hubbard U parameter on the electronic structural and mechanical properties of cubic (C-type) lanthanide sesquioxides (Ln2O3). Calculated Bader's charges confirm the ionic character of Lnsingle bondO bonds in the C-type Ln2O3. Estimated structural parameters (i.e., lattice constants) coincide with analogous experimental values. The calculated band gaps energies at the Ueff of 5 eV for these compounds exhibit a non-metallic character and Ueff of 6.5 eV reproduces the analogous experimental band gap of cerium sesquioxide Ce2O3. We have thoroughly investigated the effect of the O/Ce ratios and the effect of hafnium (Hf) and zirconium (Zr) dopants on the reduction energies of C

Design of Step-Index Multimode Optical Fiber
...Show More Authors
Abstract<p>In this paper, a step-index fiber with core index 1.445 5 1 7 and cladding index 1.443 1 5 7 has been designed and studied. Multimode operation is achieved by using a fiber with core radius 25 μm operating at a wavelength of 1.3 μm. The mode parameters (effective refractive index, phase constant, fractional modal power in the core and cutoff wavelength) were calculated using RP fiber calculator (PRO version 2020). The shapes of the intensity and amplitude distribution of linearly polarized guided modes were shown.</p>

A Review of Interface Bonding Testing Techniques
...Show More Authors

Interface bonding between asphalt layers has been a topic of international investigation over the last thirty years. In this condition, a number of researchers have made their own techniques and used them to examine the characteristics of pavement interfaces. It is obvious that test findings won't always be comparable to the lack of a globally standard methodology for interface bonding. Also, several kinds of research have shown that factors like temperature, loading conditions, materials, and others have an impact on surface qualities. This study aims to solve this problem by thoroughly investigating interface bond testing that might serve as a basis for a uniform strategy. First, a general explanation of how the bonding strength

Synthesis of anti-corrosion polymers from thiadiazole
...Show More Authors
Abstract<p>One of the biggest problems facing many industries particularly oil, is the problem of corrosion, where the metal parts under the influence of the vital factors are eroded during use and storage, therefore, to lift the metal’s ability and to protect it against corrosion, corrosion inhibitors are used. For the first time in this research, polymers which contain sulfur - heterocyclic ring with a thiadiazole base were made. Anti- corrosion polymers were made on two stages, in the first stage, thiadiazole was made from hydrazine hydrate reaction to carbon disulfide, afterwards the first product was reacted with an excess of hydrazine. In the second stage, polymers were prepared by the r</p> ... Show More
