ADDITIVE MANUFACTURING (AM)  is connected with a series of rapid heating and cooling cycles, as well as substantial temperature gradients, which result in the development of complicated thermal histories, which have a direct impact on the resulting microstructures. Due to the nature of this dynamic and far-from-equilibrium process, different microstructural features emerge. For instance, these are likely to induce changes in the corrosion characteristics of ADDITIVE MANUFACTURING (AM)  stainless steels, which have superior mechanical properties and corrosion resistance when manufactured using other production methods. Because such modifications are not fully understood at this time, inconsistencies and conflicts in the literature on the corrosion behaviour of ADDITIVE MANUFACTURING (AM)  stainless steels are regularly seen. The preparation and characterization of additively made stainless steel is the subject of this work, which provides a critical assessment. In terms of producing huge metallic structures at high deposition rates and cheap costs, WIRE ARC ADDITIVE MANUFACTURING  (WAAM)  has emerged as a viable method. This article reviews some ADDITIVE MANUFACTURING (AM)   methods used mostly with metallic materials focusing on the WIRE ARC ADDITIVE MANUFACTURING  (WAAM)  of stainless steel

Bis(2-amino-4-methyl­pyridinium) tetra­chloridocuprate(II)

The asymmetric unit of the title compound, (C6H9N2)2[CuCl4], consists of one cation and one half-anion, bis­ected by a twofold rotation axis through the metal center. The anion exhibits a geometry that is inter­mediate between a Td and D 4h arrangement about the Cu atom. The crystal structure contains chains of cations alternating with stacks of anions. The cationic groups inter­act via offset face-to-face π–π stacking, forming chains running along the c axis. The anion stacks are parallel to the cation chains, with no significant inter- nor intra­stack Cl⋯Cl inter­actions. There are several anion–cation hydrogen-bonding inter­actions of the (N—H)pyridine⋯Cl and (N—H)amino⋯Cl types, connecting the chains of cations to the stacks of anions. Both the N—H⋯Cl and π–π stacking inter­actions [centroid–centroid distances 3.61 (8) and 3.92 (2) Å] contribute to the formation of a three-dimensional supra­molecular architecture

THE ROLE OF SELF-DISCREPANCY IN GENERATING FUTURE ANXIETY AMONG UNIVERSITY STUDENTS

Purpose of the study: The current study examines the level of self-perception (realism, idealism, and duty) among Yarmouk University students. It also identifies the level of their self-discrepancy and its relation to future anxiety and explores the differences regarding the level of these self-discrepancies and the future anxiety according to the variables of specialization, the level of the study, and GPA. The study argues that while there is a significant statistical negative relationship between the level of future anxiety and the actual self among university students there is no significant statistical correlation between the level of future anxiety and the ideal self and the ought self. Methodology: The study was conducted on a sample of (200) university students of the Faculty of Education at Yarmouk University. Higgins’ (1987) scale which consists of (30) paragraphs and the scale of future anxiety which consists of (27) paragraphs were applied to the study sample using the descriptive correlational approach. Main Findings: There were no significant statistical differences regarding the level of self-discrepancy (real/ideal) and (real/due) due to the variables of specialization, the level of study, and the GPA. Also, there were no significant differences regarding the level of future anxiety among Yarmouk University students according to the variables of specialization, the level of study, and the GPA. Yet, there was a statistically significant negative relationship between the level of future anxiety and the actual self. Applications of this study: Universities across the globe, such as Yarmouk University and the University of Jordan, may find it significant to know that university students have a moderate level of self-perception and do not have a correspondence between the characteristics of the self in its three dimensions. Thus, such universities may need to think of establishing certain training and counseling programs that aim at developing the students' perception of themselves and their understanding of the self. Novelty/Originality of this study: Considering that a few Arabic studies address future anxiety among university students who will graduate and impact their local communities, the paper points at the need for establishing certain counseling courses that help university students better understand themselves and decide their needs accordingly. &nbsp
