This paper is based on the work done for the 2017 AIAA Student Design Competition-Human Spaceflight: Phobos Base. One of humanity's major challenges when travelling to Mars is represented by the existence of an atmosphere around the red planet. In fact, even though the Martian atmospheric density is only about 1% of that of Earth, the entry, descent and landing (EDL) procedure for large payloads i

We report the spectroscopic confirmation and fundamental properties of TOI−757 b, a mini−Neptune on a 17.5−d orbit transiting a bright star (V = 9.7 mag) discovered by the TESS mission. We acquired high−precision radial velocity measurements with the HARPS, ESPRESSO, and PFS spectrographs to confirm the planet detection and determine its mass. We also acquired space−borne transit photometry with t

We carried out the first high-resolution transit observations of the exoplanet WASP-49 Ab with Keck/HIRES. Upon custom wavelength calibration we achieve a Doppler RV precision of < 60 m s−1. . This is an improvement in RV stability of roughly 240 m s−1 with respect to the instrument standard. We report an average sodium flux residual of (Formula presented) per cent t (8.0σ) comparable to previous

As tech giants such as Apple and Meta invest heavily in Virtual and Augmented Reality (VR/AR) technologies, often collectively termed Extended Reality (XR) devices, a significant societal concern emerges: The use of eye-tracking technology within these devices. Gaze data holds immense value, revealing insights into user attention, health, and cognitive states. This raises substantial concerns over

AbstractBackgroundThe role of nutrient intake in celiac disease pathogenesis is poorly understood.ObjectiveTo examine whether longitudinal childhood intake of selected vitamins and minerals is associated with celiac disease autoimmunity (CDA, primary outcome) and celiac disease (secondary outcome) in genetically at-risk children.MethodsA total of 6,520 HLA-conferred at-risk children in the observa

Target cell entry of HIV-1 is dependent on the binding of gp120, the outer component of the viral envelope glycoprotein complex (Env), to CD4 and a coreceptor, preferentially CCR5 or CXCR4. Still, other interactions may also contribute to the infectivity of the virus. One such interaction is between the highly glycosylated gp120 and carbohydrate-binding proteins, such as galectins. Here, we studie

Popular Abstract in Swedish Bibeln, och framför allt Nya Testamentet, har präglat det västerländska tänkandet i en utsträckning som inte alltid noteras i nyare historieskrivning. En ledande roll har spelats av de uppfattningar av Gud som förmedlas av de fyra evangelierna. Inte minst har läsningar av Johannesevangeliet genomsyrat de kristna tänkarnas försök att formulera synen på Guds väsen, egenskThis book presents an exhaustive and systematic investigation of six representatives of three important periods of New Testament interpretation: Martin Luther, John Calvin, Brooke Foss Westcott, Heinrich Julius Holtzmann, Rudolf Bultmann and Raymond E. Brown. They serve as dialogue partners in an investigation of the notion of God in the Fourth Gospel, a topic that has been called “the neglected f

The 4MOST([1]) instrument is a concept for a wide-field, fibre-fed high multiplex spectroscopic instrument facility on the ESO VISTA telescope designed to perform a massive (initially >25x10(6) spectra in 5 years) combined all-sky public survey. The main science drivers are: Gaia follow up of chemo-dynamical structure of the Milky Way, stellar radial velocities, parameters and abundances, chemical

In vision-based feedback control systems, the time to obtain sensor information is usually non-negligible, and these systems thereby possess fundamentally different timing behavior compared to standard real-time control applications. For many image-based tracking algorithms, however, it is possible to trade-off the computational time versus the accuracy of the produced position/orientation estimat

The aim of this thesis is to examine the relationship between writing and alterity in three recent novels written by J. M. G. Le Clézio, Désert (1980), Onitsha (1991) and La quarantaine (1995), which deal with the encounter between the so-called primitive cultures and Western society. The first chapter contains a more general discussion on the discourse of alterity in literature and the French exo

When decision on repair has been taken the available repair systems/methods must be evaluated with regard to the immediate requirements. For each type and cause of damage, there are normally only a few possible repair systems. These repair systems should be evaluated with regard to following 5 basic properties, or characteristics: 1) service life/durability, 2) structural stability/safety, 3) exec

Five students of a rescue training school cycled at 50 W for 20 minutes at 20 °C before walking up to 30 minutes in a climatic chamber at 55 °C and 30 % relative humidity. Four different types of clothing ensembles were used differing in terms of thickness and thermal insulation value were tested on separate days. All subjects completed 28-30 minutes in light clothing, but quitted after 20-27 minu

Extensive studies of mice deficient in one or several cytokine receptors have failed to support an indispensable role of cytokines in development of multiple blood cell lineages. Whereas B1 B cells and Igs are sustained at normal levels throughout life of mice deficient in IL-7, IL-7R{alpha}, common cytokine receptor gamma chain, or flt3 ligand (FL), we report here that adult mice double deficient

The feasibility of administering metoclopramide (MCA) as a radiosensitizer has been evaluated in 23 patients with a pathological or cytological diagnosis of a squamous cell carcinoma of the lung, clinically evaluated as inoperable. All patients received 40-60 Gy radiotherapy fractionated into 1.8 Gy fractions 5 times per week (Monday-Friday). Two MCA treatment regimens were used: (i) MCA at 2 mg/k

Several transporter systems in the liver and intestine are known to change their expression and function during cholestatic disease states. The objective of the-present in vivo study-was to investigate the effect of biliary depletion, as a method to mimic cholestasis, on the bioavailability and disposition of digoxin in biliary and pancreatic duct cannulated pigs. The study was divided in two part

The tradition of writing books specifically for girls came to an abrupt end in the middle of the 1960's. In Sweden this was a turbulent decade when society changed in many ways, and equality between the sexes was a key word. The old girls' and boys' books were replaced by "the modern book for young people", which, it was proclaimed, should be up-to-date, discuss real problems, break taboos, and ap

Contemporary English as a foreign language (EFL) classrooms in upper secondary schools in Sweden make frequent use of receptive media such as movies and television to facilitate language learning. The more interactive medium of video games is seldom used for the same purpose, despite previous research indicating that the added layer of interactivity can bring benefits such as improvements to vocab
