In this work, the effect of a filler wire feed rate was studied with special attention to proportion porosity volume in weld metal, microstructure, and mechanical properties. Butt laser joints were created using Nd:YAG laser. Weld produced AZ31 diameter 1.2 mm. Decreasing led an increase metal. Therefore, is more likely occur welding without use wire. Clear segregation aluminium, manganese, zin...

We have investigated the properties of the two hemes bound to histidine in the H10 positions of the uniquely structured apo form of the heme binding four-helix bundle protein maquette [H10H24-L6I,L13F](2), here called [I(6)F(13)H(24)](2) for the amino acids at positions 6 (I), 13 (F) and 24 (H), respectively. The primary structure of each alpha-helix, alpha-SH, in [I(6)F(13)H(24)](2) is Ac-CGGG...

In the present study, 50 genotypes of tomatoes were tested in roll towel method using seven levels salt concentration from 0 to 120 mM NaCl with an interval 20 at laboratory conditions. Results showed that out genotypes, only 38 tomato germinated under a moderate salinity level 80mM NaCl. The highest seedling fresh and dry weights observed LE-14 (0.271 0.045, respectively) which on par LE-1, LE...

Metoksimetiltrifenilfosfonyum klorür (MOMTPPC) tek kristalleri Elektron Paramanyetik Rezonans (EPR) spektroskopi yöntemi ile analiz edilmiştir. MOMTPPC kristalleri, 60Co- kaynağı ışınlanarak paramanyetik bozukluklar oluşturulmuştur. kristallerinin EPR spektrumları, 120 K sıcaklıkta üç dik eksen etrafında belirli açılarda döndürülerek spektrumları alınmıştır. MOMTPPC'de ışınlama etkisiyle oluşa...

Cataphoresis varnishing enables an organic coating to form on aluminum substrate, thus increasing its corrosion resistance and durability. is known ensure a high adhesion of the created cataphoresis layer good homogeneity this layer, even surfaces with complex geometry. This paper aimed optimize deposition process analyze evaluate thickness formed substrate from AW 1050—H24 material. In total, ...

This paper presents a study on the dynamic behavior of thin aluminum plates subjected to consecutive fragment impact and blast loading. To this end, two separate experimental setups are used. In first setup, 2 mm thick EN-AW-1050A-H24 were ballistic fragment-simulating projectiles (FSPs). Experiments carried out for FSP calibers 7.62 12.7 considering both single triple impacts with variations i...

Pestivirus nonstructural protein 3 (NS3) is a multifunctional with protease and helicase activities that are essential for virus replication. In this study, we used combination of biochemical genetic approaches to investigate the relationship between positively charged patch on module NS3 function. The surface composed four basic residues, R50, K74 K94 in domain H24 structurally integrated cofa...
