A Hybrid censoring scheme is a mixture of type-I and type-II censoring schemes. In this research we used maximum likelihood method and shrinkage method when we take deferent values for the shrinkage parameter (K) and determined the optimal value for the shrinkage parameter. The mean square error is used to comparison between the two methods by using simulation and so used real life data, when the data are Burr-XII distribution for three parameters.

The study included 25 wound samples were collected from type 1 insulin dependent diabetes mellitus (IDDM), and type2 non-insulin dependent diabetes mellitus (NIDDM) foot patients admitted to daquq hospital of both sex and their ages between 41-75 years. The study aimed to screen the aerobic bacterial pathogens present in diabetic pus and to determine their antibiotic susceptibility against common standard antibiotics. Bacteriological diagnosis and antibiotic sensitivity profiles were carried out at two parts: The profile part swab was taken has been cultured in media of blood agar and MacConkey agar depend on biochemical tests and indicators. The results indicate that common pathogen isolates from the diabetic pus included E. coli followed by Proteus mirabilis and Staphylococcus aureus, and the peak proportion of diabetic foot ulcer (DFU) was recorded between 41-75 years in both sexes. The second step were included the performing antibiotic susceptibility according to Kirby-Bauer disc diffusion method on Mueller–Hinton agar using 11 different antibiotics. It was obvious that Nitrofurantoin, Ciprofloxacin and rifampicin is more active against E. coli followed by co-trimoxazole and gentamycin . Ofloxacin is more active against Staphylococcus aureus followed by gentamycin and Amipcillin .Amikacin, Nitrofurantoin and Co-Trimoxazole is active against Proteus mirabilis followed by gentamycin and erythromycin.

This investigation is related to study the potential of Iraqi Rice Husk (IRH) (which is considered as a type of agricultural waste that is difficult to discard in a conventional methods) on thephenolpollutant removal from wastewaterusing different design parameters by adsorption process.The design parameters studied to adsorb phenol using IRH as an adsorbent material were initial concentration of phenol, adsorbance material packingheight which was IRH, pH of phenol feed inlet,treatment time,feed flow rate and feed temperature, these parameters were varied from (1-100) mg/l, (10-100) cm, (1-8), (1-60) min, (5-100) ml/min and (20–55°C) respectively. Results show that the higher removal efficiency was89.73% for phenolfrom aquatic solution and this efficiency was decreased with increasing of initial concentration,flow rate andpH while the removal efficiency increased with increasingabsorbance material bed height and feeding temperature. Statistical model is achieved to find an expression combined all operating parameters with the removal efficiency for phenolused in this paper in a general equation.By this way we can possess different benefits which are: removal of the toxic phenol contaminated water, and get rid of agricultural waste IRH.At in the same time, we can discard more toxic waste in an eco-friendly way.

It is known, for example, that the t-statistic tables are designed primarily to deal with the results of the regression that uses static chains. This has been the former treats .assumption until the mid-seventies, where researchers are conducting studies applied without taking into account the characteristics of the time series used by an appreciation, was to accept the results of these tests and Bmanueh delivery capabilities based on the application of the theory of statistical inference on these estimators. But the scientists Granger and Newbold 1974 generate random time series is static Stationary Non (specifically conduct random strings) using simulation method these chains do not express any unknown variable and then considered these independent chains. They then conducted a large number of regression estimates using these . The researchers thus reach to an important result and that serious estimators and statistical tests that result from time-series regressions used is still considered the results of improper or false decline spurious regressions cannot be reassuring to the results of statistical inference on its resources. The form of this research a starting point for new research in the field of sleep test series, cast doubt on the results of all previous standard tests used the time series properties did not take into account the time-series before appreciation. Then came all of Engel and Granger 1987 to decide that in the case of single or sole exception are results of the assessment is fake and can apply the rules of statistical inference in the case estimate slope using two strings is, which is that leftover estimate regression equation be static, and say then that the two strings of two integration Even Co-Integration.). And on this basis was used standard methods to test stability of the time series of the variables used to estimate the function of investment in Iraq and then test their conformity to the integration of the joint in order to reach the best model for this function, which reflects the reality of investment in Iraq for the period (1982-2000)

In this paper, it has been a new design of Reticle with multi-patterns RMP to detect the laser signals that emitting from targets. The RMP is design using Auto CAD program, which consists of four patterns, each Pattern consists of twenty sectors, ten sectors are opaque and the other ten sectors are transparent for the laser. The number of sectors depends on several factors as chopping frequency of RMP, cutoff frequency of spot laser and modulation transfer function. All results obtained by design a special program named a “Reticle with Multi-Patterns RMP” which contains many parameters. To explain the impact of changing spot size of laser (As a result of the approaching target), we will change the radius of spot size between (0.1 to 0.6) cm, and then evaluate the best value of MTF which obtained when radius of spot size laser is equal 0.6 cm.
