The present study investigated and identified genetic diversity between native White chicken lines and two commercial Broiler (Rose) and Layer (Isa Brown) chicken breeds using RAPD markers and a sequencing technique. All primers applied produced 151 scorable bands with percentage polymorphic loci of 54.93 % within chicken populations, as per the results of the RAPD marker. The maximum amplified fragment by primer OPC-11 was 22 and the fewest by primer OPAA-03 was 7. For all loci analyzed, the effective number of alleles (ne), means the observed number of alleles (na), Shannon's information index (I), and gene diversity (h) was 1.4394, 1.5493, 0.3496, and 0.2441, respectively. The presence of a high number of polymorphisms and targeted (71) loci across all chicken populations indicates that RAPD-PCR techniques provide sufficient genetic distance and higher genetic variation among chicken populations. The highest identity of the blasted sequences of the 18srRNA gene of local white chicken is 90.41 % and 84.23 %. Likewise, a total of 46 and 27 nucleotides are altered with 27 and 10 gaps in both sequences for the first and second regions, respectively. According to both phylogenetic trees, the local white chicken had a stronger sense of individuality and was slightly closer to the commercial broiler breeds than the layer chicken breeds. As a result, it suggests that enhancing the local chicken line requires a broiler breeding program, as well as cross-breeding with other native chicken lines to obtain hereditarily significant new strains.

To reduce the health complications of obesity, safe therapies and effective weight loss processes must be identified with preventing weight regain at the same time.Humans have metabolic flexibility and the potential to utilise ketones as an energy source by reducing carbohydrate intake in the diet, this reduces insulin levels, and ketogenesis occurs . These conditions promote the release of excess stored fat, avoid muscle weakness, and improve insulin sensitivity. Losing weight by diet causes appetite feeling and a rise in ghrelin release , that raises the likelihood of regaining weight and is thus counterproductive to goals for weight reduction . A study's aim is to review evidence on a ketogenic diet for weight loss and metabolic illnesses like insulin resistance, lipid disorders, cardiovascular disease, fatty liver disease development, and Polycystic Ovarian Syndrome. We present a foundational understanding of dietary ketones and how they are formed.

This research concerns the synthesis of two carboxymethyl chitosan (CMCs) complexes with Cu(II) and Ni(II). The synthesized complexes were characterized using (FT-IR) showing absorption peaks in the region (566 cm-1) which belongs to the bonds of Cu(II) with carboxymethyl chitosan [Cu(CMCs)2] and (580 cm-1) which belongs to the bonds of Ni(II) with carboxymethyl chitosan [Ni(CMCs)2]. Molar conductivity was determined for both complexes [Cu(CMCs)2] and [Ni(CMCs)2] and the results showed that these complexes non-electrolytes . UV-visible has been also recorded for [Cu(CMCs)2] complex solution (0.50 x 10-3M) is absorbed at (295 nm). It is proposed that [Cu(CMCs)2] possess a square planar structure. Whereas [Ni(CMCS)2] is absorbed at (290 nm) supposing that the structure of this complexes is tetrahedral. The absorbance of both complexes can be attributed to the (π→π*).

Kirkuk gas turbine power plant is supplied by the gaseous fuel from north gas company. The results showed that the theoretical efficiency of the unit is a function for two parameters; the compressor input temperature and the pressure ratio rp . So, the pressure rp ratio depends directly on the compressor input temperature. If the net work of the unit Wnet (Wt - Wc) is taken to be an index for the performance, the efficiency ƞ will be more in summer than that in winter because of the considerable reduction in compressor work Wc , while if the specific energy produced (or consumed specific fuel SFC) is taken as an index for the performance; the actual efficiency ƞac is more in winter since the specific energy produced in winter is greater approaching (4.5 kW.hr.m-3), while it did not exceed (2.8 kW.hr.m-3) in summer, this belong to the performance improving as the load increases approaching the design load, this is prevailing on the power plant operated by the diesel, heavy fuel or crude oil.

The Annual and monthly averages of rainfall and temperature of the tow tikrit and baiji meteorological stations showed that the general annual rainfall is (185) mm. The maximum rainfall is 35.5 mm in January and the minimum is (0.0) mm in august while the general monthly averages of temperature ranging between (8.7 C° in January - 36.5 C° in july ). After calculating the potential evapotranspiration values PE by thornthwait method then derive the values of water surplus WS in order to determined the amount of water that permeates to the groundwater level for each zone in the basin. After the main elements was selected depending by equations that has been developed for each zone as follows : 26 % of rainfall permeates to replenish the groundwater in the basin when the zone A lack o opportunity to allow infiltration of rainfall to the groundwater level for both A and B zones are based on monthly averages of whole surveillance period ( 1989 – 2009 ). The soil moisture amount (SM) is 25 mm for the zone A and 75 mm for each of A and B zones. When we search in the years that exceeds the general annual averages of rainfall ( 185 ) mm , founded that there are (9) years beyond the mentioned averages and account for about (43 %) of surveillance period where the general annual average equal to (242.39) mm and maximum monthly average of the rainfall is ( 41.86) mm in march and lowest average is (0.0) mm in july and august. Depending on these years mentioned, the water surplus for both zones C and B , showed that an increase about ( 29.93) mm from the average of annual rainfall equal to (242.39) mm and (12.34 %) from the rainfall permeates to fed the groundwater in B zone. 7 % adopted as a surface runoff from the rainfall equal to (16.96) mm and the ratio groundwater recharge in C zone is equal to (12.97 ) mm. The variation in groundwater values of recharge along the basin ( A,B and C ) is only a reflection for the type and texture of the deposits on the hand and varying depths, simple differences in topography and evolution of surface water drainage especially in the western part of C zone on the other hand . while the demonstrating convergence of inventories renewed values for the three zones although they have different area and water depths pervasive in all of them but the justification for this approach the increase in area of zones A , B and C, accompanied by decreasing values of deep water permeates for each zone must be noted here that the opportunity to renew stocks of ground water for both B and C amounting to 42 % of the prospect for renewed stocks of water in the zone A as well as the presence of large quantities of leaked water from the liquefaction and sewage water in zone A .

At this paper, an experimental investigation was conducted to explore the effect of different curing methods and water cement ratios on compressive strength and density of normal weight concrete. The samples had been submitted to five different curing methods including: water curing (standard curing), air curing and three types of colored plastic bags curing including (Transparent, white and black bags). The effect of w/c ratio on compressive strength at different curing had been studied too. Test results shows that the curing by plastic bags gives accepted results compared with standard curing and better than air curing. For all kinds of referenced curing the increasing in w/c ratios decrease the compressive strength, and the density of concrete samples reduces at air and plastic bags curing compared with standard curing..
