BACKGROUND The aim of the present study was to examine the internal structure and reliability of the Attachment Insecurity Screening Inventory (AISI) 6-12. The AISI 6-12 years is a parent-report questionnaire for assessing the parents' perspective on the quality of the attachment relationship with their child aged between 6 and 12 years. METHODS The sample consisted of 681 mothers and fathers...

In the present study, the effects of the boriding process on adhesion and tribological properties of AISI 310 steel were investigated. Boriding was performed in a solid medium consisting of Ekabor-II powders at 1123 and 1323K for 2 and 6 h. The boride layer was characterized by optical microscopy, the X-ray diffraction technique and the micro-Vickers hardness tester. The X-ray diffraction analy...

Embryogenesis is the beginning of plant development, yet the cell fate decisions and patterning steps that occur during this time are reiterated during development to build the post-embryonic architecture. In Arabidopsis, embryogenesis follows a simple and predictable pattern, making it an ideal model with which to understand how cellular and tissue developmental processes are controlled. Here,...

The present study includes 50 patients symptomatic for tuberculous meningitis and 15 patients with meningitis other than tuberculosis The CSF specimens were subjected for ADA titer estimation, AFB smear preparation and molecular characterization by Nested-PCR for IS6110 gene. Out of 50 specimens 2 came AFB smear positive whereas 29 specimens came positive for Tuberculosis (TB) PCR and 21were ne...

Nowadays, Because of daily reduction of fossil fuels and environmental problems caused by using them, Fuel Cells attracted a major attention as clean and efficient way of generating electrical power. Solid Oxide Fuel Cells (SOFCs) have many advantages to other fuel cell types. High working temperature of SOFCs caused serious challenges including high oxidation rate of interconnects, Spallation ...

The application of conductive coatings on ferritic stainless steel can decrease electrical conductivity. Theaim of this research was to investigate the electrical conductivity of cobalt coated AISI 430 ferritic stainlesssteel by pack cementation technique. Coated coupons were analyzed using scanning electron microscopy(SEM). Electrical conductivity of the coated substrates was measured as a fun...

In order to improve the oxidation resistance of ferritic stainless steel, it is possible to deposit a protective coating on steel substrate. In this research through the usage of pack cementation method a coating of titanium was applied on the surface of AISI 430 stainless steel. Scanning Electron-Microscopy (SEM), Energy- Dispersive X-ray spectrometry (EDAX) and X-ray diffraction (XRD) were us...

In order to improve the oxidation and hot corrosion resistance of steels, various elements including aluminum, chromium, silicon, titanium or combination of these elements can be diffused on to the surface of steel. In this study, aluminum and titanium were simultaneously co-deposited onto the AISI 430 ferritic stainless steel substrate by the pack cementation process. Coating was examined by s...

AISI 430 ferritic stainless steel is a promising candidate for utilising as interconnects of solid oxide fuel cells due to its cost effectiveness and durability. Many methods applying coating on substrates have been developed in order decrease the degradation oxidation rate chromium volatile problems. Manganese-cobalt spinel exhibits high conductivity, thermal expansion compatible with steels, ...

Augustine

St. Augustine [5] began his life in Algeria, an apt student devoted early to the Church and seeking the Truth. His professors recognized his great skill at philosophizing and writing. As Augustine devoured writings both ancient and of his contemporaries, he fell away from the Church and toward a religious dualism sect known as the Manicheans. His mother, a very devoted Christian (later St. Moni...
