Tujuan penelitian ini adalah untuk mengetahui Pengaruh Variasi Sambungan Las Listrik Terhadap Sifat Mekanik Pelat Stainless Steel 304L. Kegiatan dilakukan di Laboratorium Teknik Mesin Politeknik Negeri Manado. Pembentukan specimen uji tarik disesuaikan standar ASTM-E8. Penelitian dapat disimpulkan bahwa pemilihan diameter elektroda dan arus las sangat mempengaruhi kekuatan las. Tegangan maksimu...

Underwater wet welding is one of the most common repair measures for corroded offshore steel structures. Few studies have been carried out systematically concerned with mechanical properties of such welds, thus current design provisions rely heavily on limited experimental data on welds made underwater and design properties for corresponding welds made in air. This paper presents a series of ex...

Thermo-mechanical behavior of the lead (Pb)-free ceramic copper column grid array (CuCGA) package under accelerated thermal cycling is characterized and compared with the conventional tin–lead (Sn–Pb) ceramic column grid array (CCGA). In situ thermal deformations of the highest DNP (distance to neutral point) copper column is measured for an initial isothermal loading of DT = 75 C and subsequen...

In this study, the carcass and commercial cuts weights and yields in broilers of different ages fed diets supplemented with probiotics were determined. A total of 336 male broiler chicks (Ross-308) were randomly allocated into three treatment groups (P0, P1 and P2). A basal diet (P0), basal diet plus 0.01% (P1) and 0.02% (P2) probiotic (Saccharomyces cerevisiae, 4x10 8 cfu g -1 ) were offered t...

Fish proteins have been reported to be more satiating than meat proteins. The objective was to determine the effect of different animal protein pre-meals on satiety. A total of ten intact female hounds were fed pork loin, beef loin, chicken breast, salmon fillet or pollock fillet. Each pre-meal was fed to contain 100 g protein. Blood was collected at 0, 5, 15, 30, 60, 90 and 120 min postprandia...

Dielectric properties for anterior, middle, tail, and belly portions of Alaska pink salmon (Oncornynchus gorbuscha) fillets were measured at frequencies between 27 and 1800 MHz from 20 to 120 C to provide insights for improving the modeling of microwave (MW) and radio frequency (RF) commercial sterilization processes of salmon products. Compositional differences contributed to the observed slig...

Texture of salmon fillets is an important quality trait for consumer acceptance as well as for the suitability for processing. In the present work we measured fillet firmness in a population of farmed Atlantic salmon with known pedigree and investigated the relationship between this trait and gene expression. Transcriptomic analyses performed with a 21 K oligonucleotide microarray revealed stro...

The inspection of various structures often detects a fatigue cracks developed during long service life. These fatigue cracks significantly reduce remaining fatigue life and fatigue strength. Influence of the initial fatigue cracks size in non-load-carrying fillet-welded one-sided transverse attachment joints on the remaining fatigue life and fatigue strength is considered in this paper. A compu...
