This paper presents a number of lessons learned while designing a proposed sterilization system for Mars Sample Return. This sterilization system is needed to inactivate any potentially hazardous Mars material on the exterior surface of the vessel containing sealed sample tubes filled with Mars rock cores, regolith and atmosphere. These returned samples would provide information on the geologic history of Mars, the evolution of its climate and the potential for ancient life. Mars Sample Return is categorized at Planetary Protection Category V Restricted Earth Return, so it is required to protect the Earth–Moon system from the biological impact of returning samples from Mars to Earth. This article reviews lessons learned in the development of a particular engineering implementation to support the protection of the Earth–Moon biosphere: the use of in situ ultraviolet LED illumination. The details of the biological efficacy of this approach or the policy-related impacts are outside of the scope of this manuscript. The lessons learned presented here include establishing design requirements for the system, the selection of a light source, optical design options, contamination control and approaches to thermal and power management.

Latar belakang. Informasi keterlibatan ginjal pada penyandang talasemia-β mayor anak masih sedikit. Disfungsi ginjal dipengaruhi berbagai faktor seperti anemia kronis, hipoksia kronis, dan hemosiderosis. Neutrophil gelatinase associated lipocaline urin (NGALu) merupakan penanda biologis dini yang sensitif dan spesifik terhadap gangguan ginjal. Tujuan. Menilai disfungsi ginjal pada penyandang talasemia-β mayor anak menggunakan NGALu. Metode. Penelitian dengan rancang potong lintang dilaksanakan Oktober–November 2018. Subjek adalah penyandang talasemia β mayor anak di RS. Hasan Sadikin yang menggunakan kelasi besi deferiprondan dipilih secara consecutive sampling. Heteroanamnesis pada orang tua mengenai riwayat penyakit dan frekuensi transfusi. Terhadap subjek penelitian dilakukan pemeriksaan feritin serum, kreatinin serum, dan NGALu. Uji statistik menggunakan uji korelasi rank Spearman dengan nilai kemaknaan p

The spectral and temperature characteristics of the magnetooptical Kerr effect and the optical properties of an La[SUP0.7]Ca[SUB0.25]Ba[SUB0.05]MnO[SUB3] single crystal are studied. The data obtained are used to calculate the components of the permittivity tensor, whose behavior is interpreted within the framework of the known models of the electronic structure of manganites.
