A family of classes in nested chain abacus and related generating functions
Abacus model has been employed widely to represent partitions for any positive integer. However, no study has been carried out to develop connected beads of abacus in graphical representation for discrete objects. To resolve this connectedness problem this study is oriented in characterising n - connected objects knows as n connected ominoes, which then generate nested chain abacus. Furthermore, the theoretical conceptual properties for the nested chain abacus are being formulated. Along the construction, three different types of transformation are being created that are essential in building a family of classes. To enhance further, based on theses classes, generating functions are also being formulated by employing enumeration of combinatorial objects (ECO). In ECO method, each object is obtained from smaller object by making some local expansions. These local expansions are described in a simple way by a succession rule which can be translated into a function equation for the generating function. In summary, this stud has succeeded in producing novel graphical representation of nested chain abacus, which can be applied in tiling finite grid
Cress Seed (Lepidium sativum) Role in the healthy Processed Spread Cheese and Its Anti-Diabetic Activity
The present study dealt with utilization of cress seeds (Lepidium sativum) in the manufacture of processed spread cheese, instead of emulsifying salt. Cress seed have also health promoting properties especially lowering glucose ratios. Cress seeds powder were prepared and added with the ingredients during manufacture of processed spread cheese at levels of six ratios (0.05, 1.5, 2.5, 3.5, 4.5 and 5.5%) compared with control (3% commercial emulsifying salt). The chemical, physical, microbiology and organoleptic properties of resultant samples were evaluated. Data revealed that processed spread cheese sample fortified with 3.5% cress seeds was the best either when fresh or during storage (8±2ºC for 3 months) and they had acceptable properties. Microstructure of processed cheese spread samples were also conducted. From nutritional view, processed cheese spread samples fortified with 3.5% cress seeds were used for feeding Adult male albino rats to study their effect on plasma glucose level. Obtained data indicated that the glucose level in plasma was significantly decreased (

Taking advantage of the interesting properties of Boubaker polynomials, the definition of Boubaker wavelets on interval [0,1) is achieved. These basic functions are orthonormal and have compact support. Wavelets have many advantages and applications in the theoretical and applied fields, and they are applied with the orthogonal polynomials to propose a new method for treating several problems in sciences, and engineering that is wavelet method, which is computationally more attractive in the various fields. A novel property of Boubaker wavelet function derivative in terms of Boubaker wavelet themselves is also obtained. This Boubaker wavelet is utilized along with a collocation method to obtain an approximate numerical solution of singular linear type of Lane-Emden equations. Lane-Emden equations describe several important phenomena in mathematical science and astrophysics such as thermal explosions and stellar structure. It is one of the cases of singular initial value problem in the form of second order nonlinear ordinary differential equation. The suggested method converts Lane-Emden equation into a system of linear differential equations, which can be performed easily on computer. Consequently, the numerical solution concurs with the exact solution even with a small number of Boubaker wavelets used in estimation. An estimation of error bound for the present method is also proved in this work. Three examples of Lane-Emden type equations are included to demonstrate the applicability of the proposed method. The exact known solutions against the obtained approximate results are illustrated in figures for compariso
The Bactericidal Effect of CO2 Laser on Pseudomonas aeruginosa Isolated from Wound and Burn Infections, In-Vitro
A total of 60 cotton swabs are collected from patients suffering from burn wound and surgical site infections admitted to Baghdad Teaching Hospital and Burn Specialist Hospital in Baghdad city during 9/2013 to 11/2013. All cotton swabs are cultured initially on blood agar and MacConkey agar and subjected for standard bacteriological procedures for bacteriological diagnosis. Twenty samples out of sixty are identified as Pseudomonas aeruginosa by conventional methods. The results of antibiotic susceptibility test illustrate that the antibiotics resistance rate of Pseudomonas aeruginosa isolates is as follows:100% (2020) for ceftriaxone, cefepime and carbencillin, 70% (14/20) for amikacin, 65%(13/20) for tobramycin, ceftazidim and gentamycin, 55% (11/20) for ciprofloxacin and norfloxacin, 50% (10/20) for piperacillin and impeneme, 30% (6/20) for aztreonam. All Pseudomonas aeruginosa isolates are investigated for detection of some virulence factors (haemolysin, protease, lipase enzymes, and extracellular pigments) and biofilm formation. The results of virulence factors reveal that all the isolates are haemolysin, protease, lipase enzymes and extracellular pigments producer, while 95% of the isolates are biofilm producer. Six isolates are selected to irradiation by using CO2 laser according to the results of antibiotic susceptibility and virulence factors at power densities (2000, 2500, and 3000) W/cm2 with exposure time (60 and 90) second. The results of CO2 laser irradiation illustrate that CO2 laser irradiation lead to a reduction in the mean value of the viable number CFU/ml of Pseudomonas aeruginosa isolates with the increase of the power density and exposure time. The results of the statistical analysis by using analysis of variance (ANOVA) one way and least significant differences-LSD show that there are statistical significant differences in the mean of the viable number CFU/ml between different power densities and different exposure times. After irradiation, antibiotic susceptibility and virulence factors tests of the irradiated strains are performed. The current study concludes that CO2 laser has bactericidal effect on P. aeruginosa isolates without any effect on its antibiotics susceptibility and virulence factors
Microbiology, diseases, and epidemiology of Kingella kingae in young children: A short review
Kingella kingae is a Gram-negative coccobacilli and it is a member of the HACEK (Haemophilus species, Aggregatibacte actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and K. kingae). HACEK organisms are typically oropharyngeal commensals and have long been recognized as a cause of infective endocarditis in children and adults. K. kingae in difficult to be recovered from cultured pharyngeal samples due to its slow growth and the high presence of resident bacterial flora, however, the organism can be better detected using PCR tests. Based on our search in PubMed and other sources, we couldn't discover any study about K. kingae originated from any Arab country. Therefore, we wrote this review to draw the attention of our physicians and clinical microbiologists on the importance of this neglected group of organisms in clinical medicine. However, this review article aims to cover the most important diseases of K. kingae in the pediatric population
