C40-NbSi2 with a hexagonal unit cell is focused as high-temperature structural material. We first attempted the fabrication of bulk products via selective laser melting (SLM) in additive manufacturing (AM) process. Strong crystallographic texture control wherein <0001> was parallel to building direction, i.e. development so-called basal fiber texture, achieved this study. The developed does not...

Aynı geometriye sahip beton numuneler üzerinde yapılan bu deneysel araştırmada numune boyutu ile nominal basınç dayanımı arasında boyutunun artması dayanımın azaldığı sonucuna ulaşılmıştır. Bu olay ve betonarmenin kırılma mekaniğinde boyut etkisi olarak adlandırılmaktadır. Eksenel yükü altında Laboratuvar koşullarında üretilen değişik dayanımlarındaki küp numunelerde yükleri elde edilmiştir. Ul...

This paper examines whether US cities’ membership in voluntary climate clubs improves the municipal bond ratings issued by S&P, Moody’s, and Fitch. We suggest that only focused on adaptation could help cities signal their resilience to risks ability service bonds. Yet, club is a of intent. By itself, it does not offer concrete evidence have adopted policies or enhanced risks. examine three club...

Concrete structures such as rigid pavements, tunnels, and runways at airports are usually subject to fatigue traffic loading during their service life. Research on the aftereffects of drying–wetting cycles coupled with alternating loads concrete erosion in saline–alkali coastal areas is considerable practical importance. For this study, we utilized specimens dimensions 100 mm × 400 strength rat...

Abstract The objective of this research was to evaluate the use Life Cycle Assessment methodology assist decision-making in structural projects reinforced concrete. Were studied models for an eight-story building, with classes compressive strength (fck) concrete ranging from 25 50 MPa. Also, were evaluated changes dimensions elements, as well consumption component materials structure. Results s...

In the present study, a high-efficiency petroleum hydrocarbon-degrading bacterium MX1 was screened from petrochemical wastewater sludge, and identified using morphological, physiological, biochemical experiments combined with 16S rDNA. Results showed that strain belongs to Enterobacter sp. The degradation conditions were an incubation time of 18 days, temperature 30 °C, pH 7, salinity 2% (w/v),...

The surface coat of the infective larvae of the parasitic nematode Trichinella spiralis was characterized with respect to its biophysical properties, morphology and composition. Labelling of larvae with the fluorescent surface probe PKH26 was lost after activation (by incubation in mammalian medium containing trypsin and bile), or following pronase treatment. Electron microscopical examination ...
