The first space-based fused deposition modeling (FDM) 3D printer is powered by solar photovoltaics. This study seeks to demonstrate the feasibility of using solar energy to power a FDM 3D printer to manufacture medical resources at the Mars Desert Research Station and to design an ultra-portable solar-powered 3D printer for off-grid environments.

Six solar panels in a 3×2 configuration, a voltage regulator/capacitor improvised from a power adapter, and two 12V batteries in series were connected to power a FDM 3D printer. Three designs were printed onsite and evaluated by experts post analogue mission. A solar-powered 3D printer composed of off-the-shelf components was designed to be transported in airline carry-on luggage.

During the analogue mission, the solar-powered printer could only be operated for <1 h/d, but was able to fabricate a functional dental tool, scalpel handle, and customized mallet splint over 2 d. Post analogue mission, an ultra-portable plug-and-play solar-powered 3D printer was designed that could print an estimated 16 dental tools or 8 mallet finger splints or 7 scalpel handles on one fully charged 12V 150Wh battery with a 110V AC converter.

It is feasible to use solar energy to power a 3D printer to manufacture functional and personalized medical resources at a Mars analogue research station. Based on these findings, a solar-powered suitcase 3D printing system containing solar panels, 12V battery with charge controller and AC inverter, and back-up solar charge controller and inverter was designed for transport to and use in off-grid communities.

Using concepts from evidence-based medicine, systems theory, and risk assessment, a standardized model was developed to accept or reject medications for use in flight. The model calculates the risk scores of medications, which can then be compared to an organization's acceptable risk tolerance.

Risk scores for each medication were established by summing the products of incidence rates and severity scores for all published side effects. The incidence of each side effect was obtained in an evidence-based manner and each assigned a severity multiplier. Using statistical analysis of the calculated risk scores of approved medications, an acceptance control chart was generated.

Range of calculated risk scores of historically approved medications was 10-9140. Six Sigma Acceptance Control Line was calculated at 1.5 SDs above the mean and was 9822. Risk score range of medications generally felt unsafe was 27,010-41,294. Risk score range of medications under consideration for approval was 986-6863.

A space mission's crewmembers are the most important group of people involved and, thus, their emotions and interpersonal interactions have gained significant attention. Because crewmembers are confined in an isolated environment, the aim of this study was to identify possible changes in the emotional states, group dynamics, displacement, and leadership of crewmembers during an 80-d isolation period.

The experiment was conducted in an analogue space station referred to as Lunar Palace 1 at Beihang University. In our experiment, all of the crewmembers completed a Profile of Mood States (POMS) questionnaire every week and two group climate scales questionnaires every 2 wk; specifically, a group environment scale and a work environment scale.

There was no third-quarter phenomenon observed in Lunar Palace 1. However, fluctuations in the fatigue and autonomy subscales were observed. Significant displacement effects were observed when Group 3 was in the analogue. Leader support was positively correlated with the cohesion, expressiveness, and involvement of Group 3. However, leader control was not.

The results suggest that time effects, displacement, and leadership roles can influence mood states and cohesion in isolated crew. These findings from Lunar Palace 1 are in agreement with those obtained from Mir and the International Space Station (ISS).

Warfighters involved in mounted operations often experience prolonged periods of tissue loading, leading to injury. Determining how anatomical structures are affected during loading aids in the prevention and treatment of injury. The purpose of this study was to develop a magnetic resonance imaging (MRI) compatible seat system that simulates a UH-60 Blackhawk in-flight sitting posture.

Eight men were scanned with a 3.0 Tesla MRI. Scans were collected with and without 6.38 psi of pressure applied to the buttocks via two air bladders and an MRI-compatible robot controller system.

Scans revealed that 6.38 psi of pressure applied to the buttocks significantly decreases total soft-tissue thickness beneath the left and right ischial tuberosities by 3.6 and 3.8 mm, respectively.

At operational load bearing pressures seen in the UH-60, the soft tissue structures of the buttocks are compressed. These findings aid in our understanding of the etiology of repetitive trauma disorders in aircrew due to prolonged sitting. This study serves as the foundation for future work examining the anatomical changes associated with prolonged restricted sitting and other operational activities. A better understanding of the anatomical characteristics associated with mounted operations is invaluable to the prevention and treatment of injuries reported by warfighters and civilian populations.

Radio communication remains important for the delivery of safety-critical information in military aviation. Pilots are exposed to high noise levels. Noise attenuation provided by certain helmets is not sufficient, and resulting noise exposure can deteriorate operational effectiveness and flight safety. A need for hearing protection that enables efficient communication is obvious, especially for fighter and helicopter pilots. One possible solution for this issue is molded communication earplugs (m-CEP). Data about the advantages and disadvantages of m-CEPs are limited.

To determine the usage rates, advantages, disadvantages and pilot opinions about m-CEPs, an anonymous survey study including 31 questions was conducted in fighter, fighter trainer, helicopter, and transport aircraft units of the Finnish Defense Forces.

Of the pilots who responded, 136 (93%) had used or tried m-CEPs and 90 (62%) were currently using them. There are many benefits to m-CEPs they seem to enhance experienced speech intelligibility, since 85% of the pilots who had experience about them reported improved speech intelligibility under difficult hearing conditions, and 93% would recommend them to other pilots. It seems m-CEPs provide equal benefits to pilots with and without current hearing problems. They were also considered better than previously used hearing protectors. Still, problems were common 82% of the pilots reported m-CEP related drawbacks, of which technical problems and discomfort issues were the most prevalent.

Most military pilots hold a positive opinion on m-CEPs and are willing to recommend their use. Technical problems and discomfort issues are, however, relatively common.

Hind limb unloading (HU) is one of the ground-based models of simulated microgravity. As bacterial and viral infections could affect the immune system, the immunologic effect of HU should be studied in a specific-pathogen-free (SPF) laboratory. ACY-241 molecular weight However, a review of the literature did not reveal any studies on the immunologic effects of prolonged HU in a murine model of allergic disease. Accordingly, the present study was undertaken to evaluate the effect of HU in a murine model of allergic asthma in a SPF laboratory.

Twenty BALB/c mice were allocated equally to Group A (control group), Group B (HU group), Group C (allergic group), or Group D (allergic + HU group). Weight gains, serum total and ovalbumin (OVA)-specific IgE, titers of IL-1, IL-5, IL-10, and IFN-γ in bronchoalveolar lavage (BAL) fluid, and histopathologic findings of the lungs were compared.

After 2 wk of HU, Group D showed significantly more weight loss (-2.0±0.2 g) than Group C (-1.1±0.4 g). Groups B and D showed significant increases in serum OVA-specific IgE as compared with Groups A and C. Group D had significantly lower titers of IL-5 (Group C 53.0±15.2 pg·ml(-1), Group D 21.9±13.9 pg·ml(-1)), IL-10 (Group C 430.8±138.3 pg·ml(-1), Group D 217.6±51.2 pg·ml(-1)), and IFN-γ (Group C 104.3±37.5 pg·ml(-1), Group D 36.7±12.8 pg·ml(-1)) in BAL fluid than Group C. Peri-bronchiolar and pulmonary infiltrations of inflammatory cells were significantly greater in Group D than in Group C.

Prolonged HU may cause significant weight loss and aggravate disease courses.

Although the induction of vection (perception of illusory self-motion) has been studied for some decades, the effect of ground surface properties on vection remains to be assessed quantitatively. This study will be helpful for designing helicopter or airplane flight simulation, because pilots often perceive optic flow on the ground surface and perceive self-motion from such flows.

Vection stimuli of variable position, size, and optic flow speed were presented in a trapezoidal area on a ground surface. Body sway was also measured.

Substantial vection was induced by stimuli on a ground surface. Increases in stimulus speed and size were each associated with stronger vection (e.g., the subjective strength increased by 50% as the speed increased from 0.375 m·s(-1) to 1.5 m·s(-1)). When the stimulus occupied a more distant section of the visual field, vection was more efficiently induced than when the nearer section was occupied (e.g., the subjective strength decreased by 50% when the nearer half section of optical flow was removed).
