In this paper we propose an experiment designed to observe a general-relativistic effect on single photon interference. The experiment consists of a folded Mach-Zehnder interferometer, with the arms distributed between a single Earth orbiter and a ground station. By compensating for other degrees of freedom and the motion of the orbiter, this setup aims to detect the influence of general relativistic time dilation on a spatially superposed single photon. The proposal details a payload to measure the required effect, along with an extensive feasibility analysis given current technological capabilities., Comment: 21 pages, 9 figures

The work was intended to evaluate the influence of different types of mulch in cultivating mini watermelon „Sugar Baby‟ at the beginning of fruiting, the experiment was installed on the campus of the Faculdade of Filosofia and Ciências Humanas of Goiatuba-GO, February-April 2015. The experimental desing used was of randomized blocks with four treatments and five repetitions, with six plants per plot. The treatments were: control (no mulch); rice husk; sawdust and waste corn silage. The plants were evaluated at 44 days after planting, the reproductive phase, however, the fruits were not ripe and the occurrence of weeds was held fortnightly, identified all the weeds present in the plot. The following variables were analyzed: number of fruits; fruit weight; fresh root mass (g); fresh weight of aerial parts (g); dry mass of roots (g); dry mass of shoots (g) and the occurrence of weed species in each treatment used. The mulch silage residue base was superior to other treatments, except for variable number of fruits per plant. The occurrence of weeds was lower when we used the sawdust treatments and silage waste., Objetivou-se com este trabalho avaliar a influência de diferentes tipos de cobertura morta no cultivo de mini melancia „Sugar baby‟ no início da frutificação. O experimento foi conduzido no campus da Faculdade de Filosofia e Ciências Humanas de Goiatuba-GO, de fevereiro a abril de 2015. O delineamento experimental utilizado foi de blocos casualizados com quatro tratamentos e cinco repetições, com seis plantas úteis por parcela. Os tratamentos utilizados foram: testemunha (sem cobertura morta); casca de arroz; serragem e resíduo de silagem de milho. As plantas foram avaliadas aos 44 dias após o plantio, na fase reprodutiva, no entanto, os frutos ainda não estavam maduros e a ocorrência de plantas espontâneas foi realizada quinzenalmente, sendo identificadas todas as plantas daninhas presentes na parcela. Foram analisadas as seguintes variáveis: número de frutos; peso de frutos (g); massa fresca de raízes (g); massa fresca da parte aérea (g); massa seca de raízes (g); massa seca da parte aérea (g) e a ocorrência de espécies de plantas daninhas em cada tratamento utilizado. A cobertura morta a base de resíduo de silagem foi superior aos demais tratamentos, exceto para variável número de frutos por planta. A ocorrência de plantas espontâneas foi menor quando utilizou-se os tratamentos serragem e resíduo de silagem.

Metals are widely used in aerospace applications, where the mechanical and thermal loads can change rapidly and very dramatically. For the best operational performance every part gets analyzed and every load case simulated. Simulations work only properly if the input variables reflect reality in an accurate way. Literature shows, that the mentioned loads have an impact on the magnetic properties of ferromagnetic materials, which needs to be verified for each material and geometry. Mechanical stress in the metal elongates the grains and aligns therefore the Weiss domains with the force path. If this is the same direction as an outer magnetic field, the required magnetization energy is lowered. A rise in temperature leads to a faster oscillation of the atoms in the lattice, which counteracts the alignment of the magnetic moments.There is currently no measurement device which can observe both effects at once, and therefore existing set ups were investigated and a new design was developed. A spring combined with a lever arm induces up to 100 MPa of stress in the specimen and the whole set up is placed in a climate chamber, to observe the effects at a temperature range from $-50^\circ $C till $120^\circ $C. A Vacoflux\textsuperscript{\textregistered} 50 Yoke closes the magnetic circle around the specimen and holds the primary and secondary coils.Hysteresis loops were measured at various frequencies, temperatures and stresses in three different materials. Algorithms were developed to find the loops of interest and make the data comparable. The effects were measurable, but different for each material and not always consistent with literature. After implementing the initial magnetization curves into a finite element model, realistic results were calculated. *****Metals are widely used in aerospace applications, where the mechanical and thermal loads can change rapidly and very dramatically.
