EFFECT OF ROTATIONAL SPEED AND DWELL TIME ON PHYSICAL AND MECHANICAL PROPERTIES OF FRICTION STIR SPOT WELDING ALUMINIUM 1100 WITH ZN POWDER INTERLAYER ADDITION

Friction stir spot welding (FSSW) is one of Tinted Serum SPF the development of solid state welding to joint lightweight materials such as aluminium.In the automotive industry, lightweight materials are needed in the structure of vehicle construction to improve efficiency in vehicles.This research aims to find out how the effect of rotational speed

Tenofovir disoproxil fumarate, the prodrug of nucleotide reverse transcriptase inhibitor tenofovir, shows high efficacy and relatively low toxicity in HIV patients.However, long-term kidney toxicity is now acknowledged as a modest but significant risk for tenofovir-containing regimens, and continuous use of tenofovir in HIV therapy is currently und

The paper presents the results of investigation Canvas on ambient air quality evaluation with respect to concentration of odorants in a vicinity of a sewage treatment plant of the LOTOS Group S.A.petroleum plant.The investigation was performed during winter season using a prototype of electronic nose and the Nasal Ranger field olfactometers.The pro

Hive thermoregulation is fundamental for the normal development Baby Safety of bee colonies and, consequently, hive productivity and honey bee health.External conditions mainly affect the walls of the hive.Therefore, hive construction materials and thermal conductivity features can influence its thermoregulation efficiency.The present trial made a
