Shortening or omitting the dry period to improve energy balance in early lactation have trade-offs of reduction milk production and loss opportunity for dry-cow therapy (DCT; i.e., intramammary antibiotic use at dry-off). Customized dry-period strategies (i.e., deciding upon DCT length per cow) could mitigate negative effects short no periods on udder health simultaneously retain benefits from ...

Electrochemical impedance spectroscopy (EIS) was used to detect stress corrosion cracking (SCC) in stainless steel 304 alloy exposed to an aqueous environment at 120 °C. Stainless steel 304 alloy as u-bend was tested in the solution that contains 40 weight percent of magnesium chloride. U-bended samples were prepared according to ASTM G30. EIS measurements were always performed simultaneously o...

Light-weight robots are robots especially designed for mobility and interaction with a priori unknown environments and with humans. These applications pose the requirements of a light-weight design with high load to weight ratio and high motion velocity (close to the approximately 1:1 ratio of human arms at a tip velocity of 6m/s). Further, they require a modular, integrated mechanical and elec...

regarding the increasing demand for lightweight concrete especially lightweight structural concrete, and safety requirements underlined in 2800 iranian standard, research to achieve the optimized results in lightweight concrete production seems inevitable. since, one of the commonly used methods for producing the light eight concrete, utilizes the light weight aggregates with significant role i...

Self Compacting Concrete (SCC) is a self-compacting concrete with fairly high slump value. For the manufacture of it will be faster and more economical so that able to produce precast products are planned for road complementary buildings. In this study, researchers used 3 variations local sand from South Sumatra added material in form superplasticizer ligno P-100 levels 1.5%, 2% 2.5% by weight ...

Self-compacting concrete (SCC) was developed to overcome the challenges of placement in dense or congested reinforcement structure, where can flow under its own weight fill densely reinforced structure. However, production SCC mostly involves use high cement achieve desired strength. Therefore, reduce needed amount cement, pozzolanic materials such as fly ash be used partially replace cement. h...

Here, we present a case of a 78-year-old man that underwent gastrointestinal endoscopy because of one- monthhistory of dysphagia to liquids and solid foods with accompanying weight loss. On endoscopy, there was distalesophageal stenosis. Multiple biopsies were obtained. Histologic examination of the samples revealed normaltissue. The stenosis was treated by dilatation and abdomino pelvic comput...
