Lutzomyia intermedia (Lutz & Neiva, 1912) and L. whitmani (Antunes & Coutinho, 1939) (Diptera: Psychodidae: Phlebotominae), two important vectors of American cutaneous leishmaniasis in Brazil, occur in sympatry in the locality of Posse county, Petropolis municipality, state of Rio de Janeiro, Brazil. We investigated the influence of the lunar cycle on the frequency of specimens of the two speci...

Introduction: Crystallization of the lunar magma ocean occurred ~4.4 Ga [e.g., 1-4] and produced three principal magma source regions [5-6]. These sources are characterized chemically by low titanium (Ti), high Ti, and high potassium, rare earth element, and phosphorous (KREEP) abundances. The KREEP component was produced after nearly complete solidification of the magma ocean and is highly enr...

Oxygen and iron isotope analyses of low-Ti and high-Timare basalts are presented to constrain their petrogenesis and to assess stable isotope variations within lunar mantle sources. An internally-consistent dataset of oxygen isotope compositions of mare basalts encompasses five types of low-Ti basalts from the Apollo 12 and 15 missions and eight types of high-Ti basalts from the Apollo 11 and 1...

The applicability of a nightlight lift-net for sampling ichthyoplankton assemblages was evaluated in inshore habitats off southwestern Puerto Rico. The effects of lunar periodicity, habitat, light duration, and gear type (nightlight vs. plankton tow) were investigated. Overall, 36 piscine taxa were collected with the nightlight lift-net from inshore habitats (i.e. coral reef, mangroves, seagras...

Introduction: With the recent return of remote sensing evidence for aqueous alteration on Mars in the form of evaporates and other secondary minerals (MERs [e.g., 1] and Mars Express [e.g., 2]), understanding the differences between weathering processes on Mars and Earth becomes imperative. Martian meteorites provide the only available source of detailed geochemical analyses of Martian material...

Introduction: Crystallization ages of lunar impact melt rocks provide the primary evidence for a spike in the impact flux at ~3.9 Ga. Here we report U-Pb isotopic ages of accessory phases (apatite, zirconalite) in lunar melt breccia 67955 that confirm a crystallization age of ~4.2 Ga and reveal a younger overprint possibly related to entrainment of the breccia by one or more younger basins such...

In the 21 st Century, space exploration will focus on surface exploration, with human-robotic collaboration allowing extended-duration stays at challenging lunar and planetary sites. This paper focuses on three early phases of lunar exploration: (i) in-situ characterisation and site survey for science, prospecting and reconnaissance in advance of human sorties (ii) in-situ human sortie field as...

The second and third phases of the Chinese Lunar Exploration Program (CLEP) are planning to achieve Moon landing, surface exploration and automated sample return. In these missions, the inertial navigation system (INS) and celestial navigation system (CNS) are two indispensable autonomous navigation systems which can compensate for limitations in the ground based navigation system. The accurate...

OBJECTIVE The belief that the full moon and disturbed behaviour are closely linked is alive and well, despite studies to the contrary. We investigated the possibility that there is an association between only extreme behavioural disturbance and the full moon. DESIGN, SETTING AND PARTICIPANTS We undertook an observational study of patients with violent and acute behavioural disturbance who pre...
