As life progresses and develops, cryptography has become an indispensable science. The development of this science has given flexibility and security in exchanging information and data of various kinds by making it difficult for unauthorized persons to access them. In this paper, we proposed a new NTRU-like encryption scheme using a different mathematical structure for the public key, as well as for text encryption and decryption to have more resistance to attacks, which makes this method suitable for many applications.

Numerous organic compounds have been investigated for their potential to reduce corrosion under various circumstances. This study investigated the effects of di-dodecyl amine, an organic chemical, on carbon steel metal corrosion at different temperatures while HCl acid was present. The examination was carried out using accepted methods for polarization, weight loss, and corrosion process testing. The obtained findings demonstrated that the corrosion rate reduces with increasing inhibitor concentration, leading to increased inhibition efficiency. Furthermore, as shown in the weight loss technique, the corrosion rate lowers with increasing surface coverage with organic inhibitor at 313 °C. In the anodic and cathodic polarization methods, as well as in the inhibition efficiency, it is observed to see the cathodic and anodic curves through which the occurrence of the potential and corrosion current is known. The current and corrosion potential decreases with increasing inhibitor concentration. The amines and methyl motiveless in this inhibitor's composition give it their efficacy since they may coat the metal surface and stop corrosion

Urinary tract infections (UTIs) considered as a serious public health issue, especially in children, which can be caused by a variety of organisms, especially gram-negative bacteria. Procalcitonin (PCT) is a precursor of the calcitonin hormone, which normally released in the thyroid gland, and this biomarker has become more effective in diagnosing bacterial infections in the last decade. Moreover, to establish the utility of procalcitonin for predicting urinary tract infections in children. The current study included two groups of patients of approximately sixty cases from patients with urinary tract infection (UTI), besides, sixty cases from healthy individuals. Samples were collected from Al Imamain Al-Kadhimain Medical City in Baghdad. The result showed a highly significant difference in procalcitonin levels in UTI patients compared to the control group. The results of this investigation support the use of PCT as an indicator for the diagnosis of UTI children.
