Maxwellian-Averaged Neutron Capture Cross-Sections and Thermonuclear Reaction Rates for 56,57,58Fe, 59Co, And 60Ni Isotopes at Astrophysical Energies
Abstract<p>Initially-produced isotopes during the course of the <italic>s</italic>-process have a significant impact on the continuity and branching network of this process. Such isotopes can undergo various neutron capture mechanisms, of which (n, <italic>γ</italic>) is important. In this research, the direct, thermal, and Maxwellian-averaged cross section (MACS), as well as the astrophysical reaction rates of the radiative neutron-capture reactions, were calculated for <sup>56,57,58</sup>Fe, <sup>59</sup>Co, and <sup>60</sup>Ni isotopes. At kinetic energies between kT = 0.037 and 482.3 keV, corresponding to astrophysical temperature in the range of 0.01 to 1GK. E1 transitions of <italic>s</italic>-wave were considered with the approximations of direct non-resonant components. The obtained MACSs and hence reaction rates were based on the data from the major measured and evaluated nuclear libraries and tables and they showed very well agreements with the most recommended database and compilations. Moreover, the effect of the direct, thermal, and negative resonance cross sections on the MACS was found to be very small and exhibit a 1/v behavior overall temperatures, with a maximum at <italic>T</italic> = 0.01GK, while the main contribution attributed to the positive resonance term, that found to dominate overall temperature range.</p>

Formulation and In Vitro Evaluation of Taste- Masked Prednisolone Orodispersible Tablets

Background: prednisolone is a corticosteroid with a very bitter taste acts as anti- anti-inflammatory and immune suppressant drug and it is used at any age.

Objective: To improve patient compliance by masking the bitter taste of the drug to be delivered as an orodispersible tablet.

Methods: External ionic gelation using sodium alginate (0.5%w/v) and calcium chloride (1% w/v) in presence of 0.5% w/v carbopol 940 was used to prepare taste masked beads loaded with prednisolone to be compressed as orodispersible tablets.  

Results:  The bitter taste of was masked by preparing beads composed of 1:1:1 (sodium alginate: Carbopol 940: prednisolone) which r

The Sufian Symbol and its significance in Abd Allah Hamadi's Poetry

This research paper looks to put its hands on sufi symbols which are applied by the algerian poet د abdallah hammadi د in his poetical works . the symbols it relies on are : ( symbolisme of wine . symbolisme of light . symbolisme of night . sufisme and nature , femal symbols ) .
From these symbols we try to show its range of ability to apply it , with trying to determine its meaningful , dimensions .

Isolation and Characterization Salt Tolerant Strains Of Rhizobium leguminosarum bv. Viciae

Seven strains of Rhizobium leguminosarum bv. vicide were isolated
and purified from the root nodules of faba bean (Viciae faba) plants
collected from different agroclimatic locations in Baghdad and Diyala
provinces of Iraq. Screening of these strains gives four salinity tolernat  strains which tolerate 1-5% sodium chloride supplement mannitol to  salt yeast extract (M Y) medium. Colony forming units for the four tolerant strains under stress conditions were significantly reduced in comparison with those under normal conditions. Different tests were used to study the surface properties of stress tolerant strains under  normal and stress conditions. No differences were found in the production of lipopolysaccharid

Towards Generating Robust Key Based on Neural Networks and Chaos Theory

There are large numbers of weakness in the generated keys of security algorithms. This paper includes a new algorithm to generate key of 5120 bits for a new proposed cryptography algorithm for 10 rounds that combine neural networks and chaos theory (1D logistic map). Two methods of neural networks (NN) are employed as Adaline and Hopfield and the results are combined through several sequential operation. Carefully integrating high quality random number generators from neural networks and chaos theory to obtain suitable key for randomness and complexity.

Stream of Consciousness Technique: Psychological Perspectives and Use in Modern Novel

Stream of Consciousness technique has a great impact on writing literary texts in the modern age. This technique was broadly used in the late of nineteen century as a result of thedecay of plot, especially in novel writing. Novelists began to use stream of consciousness technique as a new phenomenon, because it goes deeper into the human mind and soul through involving it in writing. Modern novel has changed after Victorian age from the traditional novel that considers themes of religion, culture, social matters, etc.  to be a group of irregular events and thoughts interrogate or reveal the inner feeling of  readers.

This study simplifies stream of consciousness technique through clarifying the three levels of conscious

Vascularization of Leaves and Stem of the Species Galium Aparine L.

The research is an anatomical study for the stem and leaves of Galium aparine
L.The nodal anatomy was carefully investigated ,by the cross sections at the node
provide that what was called "cyclic arrangement" of leaves is in fact includes just
two opposite leaves which take their vascularization from the stele by two leaf
traces.The rest four leaf- like appendages on the node are stipules ,and take their
vascularization from the vascular ring which bond the two opposite leaves,and
refered for some morphological and anatomical characters of the plant species in this
work.

The political participation of the Iraqi woman Between ambition and challenges

The political participation of the Iraqi woman, gains a big importance equivalent to its role in all other fields. Therefore , it represents a higher value in the democratic orientation in addition to the importance of rising the reality of the woman specifically in the fields that are considered as a scale of the human development like the income, health, and education . The weakness of womenʹs political participation, is something that can't be ignored or neglected if we are looking forward to the rising of the country᾽s reality and achieving the required development in its all aspects. The woman is half of society or more than that due to the burden of raising the generations tasks. This can be achieved by taking part in th
