Evaluation of the Physical and Chemical Treatment of Wastewater for the Dairy Industry
...Show More Authors

Dairy wastewater generally contains fats, lactose, whey proteins, and nutrients. Casein precipitation causes the effluent to decompose into a dark, strong-smelling sludge. Fluid waste contains soluble organic matter, suspended solids, and gaseous organic matter, which cause undesirable taste and smell, grant tone and turbidity, and advance eutrophication, which plays an essential role in increasing biological oxygen demand (BOD) in water. It also contains detergents and disinfecting agents from the rinses and washing processes, which increase the need for chemical oxygen (COD). One of the characteristics of dairy effluents is their relatively high temperature, high organic contents, and wide pH range, so the discharge of wastewater into water bodies without treatment leads to deterioration of water quality and ecological imbalance, and therefore treatment is required. To remove or reduce environmental damage. Dairy wastewater treatment includes mechanical, physical, chemical, and biological methods.

Organic treatment techniques are reasonable for treating wastewater from the dairy business because of their high biodegradability. Notwithstanding, the long-chain unsaturated fats framed during lipid hydrolysis show an inhibitory impact during anaerobic treatment. Chain block reactors (SBR) and top stream anaerobic slop cover of sludge (UASB) frameworks are the most encouraging advancements for the organic treatment of dairy wastewater. Many papers have applied high-impact exercise and technical methods to the dairy business's anaerobic wastewater treatment of dairy wastewater. However, the two techniques actually have a few disadvantages. The most vital objective of these studies is to track down savvy and naturally manageable ways to deal with and empower the reuse and management of wastewater and waste. Consequently, elective treatments to organic treatment are physical and substance techniques, for example, coagulation, retention, layer cycles, and electrolysis. This section gives a primary survey zeroing in on physical and compound treatment strategies for dairy wastewater treatment. It is under study and checked for its viability.

Bayesian Estimator for the Scale Parameter of the Normal Distribution Under Different Prior Distributions
...Show More Authors

In this study, we used Bayesian method to estimate scale parameter for the normal distribution. By considering three different prior distributions such as the square root inverted gamma (SRIG) distribution and the non-informative prior distribution and the natural conjugate family of priors. The Bayesian estimation based on squared error loss function, and compared it with the classical estimation methods to estimate the scale parameter for the normal distribution, such as the maximum likelihood estimation and th

Modifications to Accelerate the Iterative Algorithm for the Single Diode Model of PV Model
...Show More Authors

This paper discussed the solution of an equivalent circuit of solar cell, where a single diode model is presented. The nonlinear equation of this model has suggested and analyzed an iterative algorithm, which work well for this equation with a suitable initial value for the iterative. The convergence of the proposed method is discussed. It is established that the algorithm has convergence of order six. The proposed algorithm is achieved with a various values of load resistance. Equation by means of equivalent circuit of a solar cell so all the determinations is achieved using Matlab in ambient temperature. The obtained results of this new method are given and the absolute errors is demonstrated.

Factors affecting the support of local investment in iraq for the period(1996-2015)
...Show More Authors

This paper aims to explain the effect of the taxes policy including direct & indirect taxes on supporting the domestic Investment in Iraq. This could help the official planners for drawing the future policies that help provoking (istumlating) the domestic investment in Iraq the quantitative analysis approach was adopted using regression model. The results showed the significance of the effects of both direct & indirect taxes policies on domestic as a simple correlation coefficient ( r ) of ( 0.6 ) , ( 0.64 ) respectively.

Influence of the annealing time on the structural properties for Flash evaporated InSb films
...Show More Authors

Indium Antimonide (InSb) thin films were grown onto well cleaned glass substrates at substrate temperatures (473 K) by flash evaporation. X-ray diffraction studies confirm the polycrystalline of the films and the films show preferential orientation along the (111) plane .The particle size increases with the increase of annealing time .The transmission spectra of prepared samples were found to be in the range (400-5000 cm-1 ) from FTIR study . This indicates that the crystallinity is improved in the films deposited at higher annealing time.

Calculation of the Longitudinal Electron Scattering Form Factors for the 2s-1d Shell Nuclei
...Show More Authors

Inelastic longitudinal electron scattering form factors have been calculated for isoscaler transition
T = 0 of the (0+ ®2+ ) and (0+ ®4+ ) transitions for the 20Ne ,24Mg and 28Si nuclei. Model
space wave function defined by the orbits 1d5 2 ,2s1 2 and 1d3 2 can not give reasonable result for
the form factor. The core-polarization effects are evaluated by adopting the shape of the Tassie-
Model, together with the calculated ground Charge Density Distribution CDD for the low mass 2s-1d
shell nuclei using the occupation number of the states where the sub-shell 2s is included with an
occupation number of protons (a ) .
