The aim of this study was to evaluate the effect heat treatment on phase composition, hardness, and abrasion wear resistance hard-anodized layers (HAL) 1011 aluminum alloy. X-ray diffraction analysis revealed Al2O3·3H2O in structure HAL synthesized for 1 h. While heat-treated HAL, oxide phases α-Al2O3(amorphous) γ-Al2O3(amorphous) types were found. Treatment at 400 °C h increased microhardness ...

The disappearance of ribosomes in Escherichia coli cells starved for a carbon source was studied. We used a series of mutants, some of them lacking in ribonuclease I(RNase I, EC 2.7.7.17), and other containing various combinations of modified polynucleotide phosphorylase (PNPase, EC 2.7.7.8) and modified ribonuclease II (RNase II, EC 3.1.4.1). RNA was prepared from the starved mutant cells and ...

The size of grains in gravel and conglomerate deposits is most easily measured on photos taken from related outcrops. However, the occlusion by sedimentary matrix or other grains, possible distortions photos, could introduce a bias such datasets. Here, we explore uncertainties associated with datasets where lengths were photos. To this end, analysed coarse-grained (>2 mm) fluvial material pit (...

The objective was to evaluate the correlation between environmental temperature-humidity index (THI), rectal temperature (RT), plasma cortisol concentration and pregnancy rate in embryo recipient cows Amazon biome. Embryo recipients (n=235) underwent estrus synchronization via simplification of P36 protocol for Fixed-Time Transfer (TETF). On days zero (D0), eight (D8) day 16 (D16), measured, as...

Annealing, quenching, natural and artificial aging at 100 200°С during 15 30 minutes of Al-Cu-Mg alloy D16 (AA2024) are provided. Chemical composition solid solution is found using scanning electron microscopy micro-X-ray-spectral analysis. Based on results chemical analysis the calculation average interatomic distance changing in found, which shows value crystal lattice distortion. Also distor...

Setiap proyek konstruksi akan selalu memunculkan dampak yang positif dan negatif, satu negatif muncul akibat pembangunan adalah munculnya sisa material atau disebut dengan construction Waste dapat memicu permasalahan baru. Terjadinya ini tidak dibiarkan begitu saja karena mengganggu proses pelaksanaan secara keseluruhan merugikan bagi pemilik kontraktor sendiri. Hal memakan banyak tempat di dal...
