Proverbs concerning food and eating abound in our society. From “You are what you eat” to the well known adaptation “A Mars a Day.....!”. Eating is an important physiological event with significant health implications. We all need to consume a certain number of nutritional elements in our diet, thus the often quoted ‘balanced diet’. However, food and eating also have great social and cultural s...

BACKGROUND: The brain is very susceptible to damage from oxidative stress due undernutrition. Provision of nutrients and compounds that act as antioxidants needed improve in the brain. AIM: This study was conducted with aim proving potential combination pasak bumi (Eurycoma longifolia Jack), DHA, seluang fish (Rasbora Spp.) brains undernourished rats (Rattus norvegicus). METHODS: Once were unde...

Ground settlement is often the most serious concern when tunneling under an old city with numerous historic monuments. A successful engineering design under these conditions would require getting the most out of the ground strength parameters and avoiding any weakening maneuver throughout the operation. Knowing that surface settlement is highly affected by tunneling parameters in EPB shield tun...

The design of relief wells includes determination of the distance of relief wells from each other, their distance from the dam upstream, the well diameter and discharge into each wells. This study tends to investigate these factors effect on uplift pressure in earth dams. For this purpose, finite elements method (FEM) was used for different configuration of relief wells in downstream of an eart...

The in-orbit results and lessons learned of the first Finnish satellite Aalto-1 are briefly presented in this paper. Aalto-1, a three-unit CubeSat which was launched June 2017, performed AaSI (Aalto Spectral Imager), Radiation Monitor (RADMON), Electrostatic Plasma Brake (EPB) missions. partly fulfilled its mission objectives allowed to either perform or attempt experiments. Although attitude c...

Model parameters of conditioned soils in head chamber of shield machine are determined based on tri-axial compression tests in laboratory. The loads acting on tunneling face are estimated according to static earth pressure principle. Based on Duncan-Chang nonlinear elastic constitutive model, the earth pressures on head chamber of shield machine are simulated. The variation of earth pressure on...

Abstract. This work uses the Disturbance Ionosphere indeX (DIX) to evaluate ionospheric responses equatorial plasma bubble (EPB) events from 2013 2020 over Brazilian and low latitudes. We have compared DIX variations during EPBs ionosonde All-Sky Imager data, aiming physical characteristics of these events. Our results show that was able detect EPB-related TEC disturbances in terms their intens...
