High speed parallel optical adder for quaternary signed-digit number usingdigit-decomposition-plane representation

Journal of Basrah Researches (Sciences), Volume 32, Issue 2, Pages 1-11

A simple optical scalable parallel and high-speed 2D data array adder for quaternary signed-digit (QSD) number is presented in this paper. The 2D QSD data arrays are coded with the digit-decomposition-plane (DDP) representation. The proposed algorithm performs parallel QSD addition in constant time independent of the size of the QSD data arrays. The methodology design is based on logical formulas which are newly derived to implement optically the suggested QSD adder. The optical implementation of the proposed adder is achieved using classical optical tools to realize the logical formulas. The simulation results of the addition operation insure that the proposed QSD adder works successfully A simple optical scalable parallel and high-speed 2D data array adder for quaternary signed-digit (QSD) number is presented in this paper.

Journal of Basrah Researches (Sciences), Volume 32, Issue 2, Pages 12-25

The nuclear level structure of Ge64-70 is analyzed taking into account the experimental information available, with respect to symmetry of IBM-3. The level energies, electric quadrupole reduced transition probability B(E2), magnetic dipole reduced transition probability B(M1), interband B(E2) ratios and multipole mixing ratios δ(E2/M1)are compared with available data. The adopted level schemes and the mixed symmetry states properties are discussed in the framework of isospin symmetry.

Journal of Basrah Researches (Sciences), Volume 32, Issue 2, Pages 26-30

This paper deals with the measurement of 222Rn in dwellings of Babil city for the first time in Iraq, using Solid State Nuclear Track Detectors (SSNTDs). The plastic detectors used in this survey were LR-115 type II.The levels of Radon measured in Babil are ranging from 5 Bq m-3 to 35 Bq m-3 compared with that in Karbala city 14 Bq m-3 [4], as well as in Sweden 100 Bq m-3 [6] and Finland 70 Bq m -3. The variation of radon concentration with height of the floor is also discussed.

Journal of Basrah Researches (Sciences), Volume 32, Issue 2, Pages 31-39

The influence of the laser beam focusing condition on the efficiency of the localized interaction with the gas indicated and the method proposed for increasing this efficiency in the presence of hot burning plasma are studied. The intensity distribution of the laser radiation in the focal plane and in the adjacent region of the laser beam is determined. Our calculations depended on the solution of two-dimensional Navier-Stokes equations together with paraxial ray equation; ionisation equation and the energy equation. A finite differences Algorithm employed to solve these equations. The active area divided into 3321 non-uniform mesh. All calculation depends on the real gas properties including the absorption coefficient. Some results will be present in this paper.

Journal of Basrah Researches (Sciences), Volume 32, Issue 2, Pages 40-49

The  and (+ + E.C.) decays of 192Ir to the levels of 192Pt and 192Os respectively have been investigated. HPGe detector was employed for the measurements of the -ray energies and relative intensities allowing the logft values, spins and parities deduced.
Two new transitions and one new level at 1439 keV for 192Pt and one level at 737 keV for 192Os are suggested. The energy level scheme of 192Os and 192Pt has been established on the basis of energy sum considerations. Comparisons are made with predictions of the interacting boson model calculated on the basis of an O(6) for 192Pt and SU(3)  O(6) transition for 192Os.

Determining the linear equivalent of NLFFS by using cyclotomic cose

Journal of Basrah Researches (Sciences), Volume 32, Issue 2, Pages 53-58

Any given periodic sequence can be generated by a family of linear feedback shift registers (LFSR ) . The member of this family with least number of stages is called the linear equivalent of the given periodic sequence. Nonlinear logic (multiplication ofachosen number of bits and modulo 2 addition of the resultant), when applied to the LFSR sequences gives an output sequence called the nonlinear feedforward sequence (NLFFS) with increased complexity . The problem of finding the complexity (linear equivalent) of NLFFS has been studied by using cyclotomic costs for the case when feedback is a primitive polynomial.

Schistosoma haematobium infection was studied among 1118 individuals in Rumman, Al-Qaim district during the period from Oct., 1995 to Aug., 1996, using Nuclepore filteration technique Prevalence of infection was found to be 8.5 %, while the intensity of infection was 1.797±0.451. Individuals with history of haematuria had higher prevalence and intensity of infection 40% and 47% if infected individuals had macroscopical haematuria and protienuria respectively.Individuals with history of treatment had significantly lower prevalence and intensity of infection. Farmer's families revealed significantly higher prevalence and intensity of infection than other occupations.

To examine the possibility that the storage of blood or serum can cause an effect on some blood parameters, the concentrations of total cholesterol (TC), urea, uric acid, Sodium (Na+), potassium (K+) and chloride (Cl-) were determined in the blood or serum samples, stored at 4oC, during 0, 2, 4, 6 hours as well as at 1, 2 and 6 days.

Journal of Basrah Researches (Sciences), Volume 32, Issue 2, Pages 82-87

The antioxidant properties (antioxidant activity, chelating activity to ferric ion and total phenolic compounds) of ground dried orange were studied. Antioxidant activity was studied in both system. The oxidation of linoleic acid compaired with synthetic antioxidant. Butylated hydroxy toluene (BHT) system and the ground beef system. At three levels 2%, 4% and 6% and the sample (raw and cooked) stored in refrigerator at 5Co for 9 days another samples stored at freezing (-18 ± 2Co) for 6 months. The results showed that the ground dried orange has antioxidant activity compaired with BHT, and it exhibited ferric ion chelating capability. The thiobarbituric acid test indicated that at 2%, 4% and 6% (w/w) levels dried orange reduced rancidity development in both frozen and unfrozen meats. There were non significant differences among various concentration of dried orange on the thiobarbituric acid value.
