Biscuit produced from wheat flour (WF 100%) supplemented with sweet potato powder (SPp) and pumpkin powder (Pp) at three level (5,10and15%) to enrich vitamin A and replacement sugar with black strap molasses to produce biscuits enriched with iron. The products were analyzed chemically and organoleptic evaluation was carried out. The results indicated the high contents of vitamin A found in Pumpkin powder (Pp) followed by sweet potato powder (SPp) with12663.67 and 8551.33 IU/100g respectively. As a result of supplemented sweet potato powder (SPp) and pumpkin powder (Pp) to wheat flour (WF 100%) gave higher vitamin A content (1041.33,1777.33,1041.33 and 1458.33 IU/100g respectively on other biscuit samples. The lowest level of vitamin A supplemented both of 10 % with sweet potato powder (SPp) and pumpkin powder (Pp) were 666.67 and 877.33 IU /100 g respectively in biscuit formula. On other hand iron content was higher in biscuit formula with black strap molasses than control. The percentage of iron content was increased from 1.40 to 5.90 mg /100g respectively for all biscuit formula. Evaluation of organoleptic properties clearly indicated the best tow samples, the supplemented with 10% sweet potato powder (SPp) and 5%pumikin powder (Pp) .showed that the best overall acceptability and ability value were (76.04 and 91.40 %), The quantities of this two chosen samples covered the daily requirement of vitamin A for children (9-12 year) showed that 137.11g and 192.1g from tow best samples .Supplementing both of sweet potato and pumpkin powder to wheat flour improved protein efficiency ratio and biological value (2.91, 2.86 ,80.52, 79.99). finally, results indicated that Supplementing both of sweet potato and pumpkin powder to wheat flour at different levels with replacement sugar by black strap molasses were optimal for producing of biscuits riches in vitamin A and iron content .

Over the past decades, the term -artificial lift- has mainly referred to the conventional techniques of downhole pumping (e.g., electrical submersible, sucker rod, progressing cavity, others) and gas lift. Today, a more comprehensive definition is becoming evident, a definition which matches all the major changes happening in the oil & gas industry. Accordingly, artificial lift is not limited to techniques conducted in the wellbore; instead, techniques used throughout the whole production system to "lift" the produced fluids towards their final destination are included. All petroleum wells’ production lives are brought to an end when the downhole reservoir pressure cannot deliver fluids traveling up to the processing facility due to high flowline pressure. Numerous technological approaches were practically implemented at many fields, approaching the end of their lives, to extend the field exploitation. One such technique is to introduce Multiphase Pumps to add energy to the unprocessed crude at the wellhead to transport oil / gas / water mixture to the Central Processing Facility (CPF) -without the need for preliminary separation or well interventions, to install downhole equipment- while maintaining an environmentally friendly performance as gas flaring is no longer required and oil spills are avoided. This paper aims at addressing the difficulties in the evaluation of multiphase Pumps; especially those handling high gas volume fraction (GVF). These problems are related to uncertainty about the approach adopted to test the pump. Minimal information about the multiphase pump performance leads to difficulty for any new pump model to evaluate its applicability as the performance curve of the pump is dependent on the inlet fluid properties, such as fluid inlet pressure, temperature, water cut, GVF, etc. Therefore, the correct prediction requires the evaluation of the pump performance for each change in fluid properties. The results of this study clearly demonstrate the tremendous effect of multiphase pumps in reactivating dying wells and enhancing production from brown fields providing a cost effective solution rather than conventional methods. Some operation challenges are very important to be considered especially when operating the pump at high GVF as a liquid recirculation system is required coupled with precise evaluation of system operational parameters to avoid gas flashing within the pump leading to reduction of pump efficiency. As well, solids handling measures upstream of the pump are essential to enhance the integrity of the system. This systematic, transformative research aims at improving our understanding of multiphase pumping and optimizing the operation parameters of Twin-screw pumps through data-driven models and field experiences leading to production optimization and sustainable future profitability.

In the present research, the effect rough corrugated bed channels on the sediment transport and of the flow passes is studied. Hypothetically, four scenarios of bed cases are tested. In the first case, using large eddy simulation, LES, an investigation of smooth bed is performed for R eT equals 395 (number of Reynolds calculated using the mean friction velocities at wall). The other three corrugated sinusoidal bed shape cases are assumed with different amplitudes and constant wavelengths. An eddy viscosity model which is adapted to wall is applied in this research; while the subgrid scale quantity is depend on the hypothesis gradient. A comparison between data of Cherukat et al. [5] obtained from Direct Numerical Simulation, DNS, and the data measured by Hudson et al. [11] with the corresponding computed flow is done. Then, wavy sinusoidal bed shape case is considered. From this study, it was found that the flow is affect strongly by the bed corrugations and the sediment transport is more sensitive for the larger heights of bed corrugations. Also, it is proved that the Rouse theory could be applied clearly in outer zone of the corrugated bed. It is explained generally in this paper that the profiles of turbulent Schmidt number are not affected by the height of corrugation.

The effects of paclobutrazol (PBZ) on growth, yield and anatomical structure of peanut plant infected with pod rot pathogens were investigated. Treatments with PBZ at 250 and 500 ppm decreased plant height but increased shoot dry weight, number of branches and pegs per plant, 100 pod weight (g) and 100 seed weight (g). Soil infested with either Fusarium solani or Rhizoctonia solani reduced all above mentioned parameters. R. solani was more virulent than F. solani on plant growth and yield. Treatment with PBZ at 250 and 500 ppm partially reduced the injurious effect of soil infested with either F. solani or R. solani. PBZ at high concentration (500 ppm) was more effective in this respect.Anatomically, the most striking anatomical changes occurred in the infected stems and carpophore with R. Solani are complete destruction of the epidermis, severe plasmolysis in the cortex followed by hydrolysis or dissolution of cell components and degradation of the primary cell walls leading to cell separation and some area of cortex tissue. In addition, dissolution and degradation of cell components accompanied with breakdown and separation were found in some regions of pod shell and the cotyledons.
