A technology that has only been recently introduced into astronomy and space exploration is infrared thermography (IRT) using uncooled microbolometer arrays (UMBA) to capture images. Assistant Professor Tetsuya Fukuhara, from the Department of Physics at Rikkyo University, Tokyo, Japan has been pioneering its use and over the last decade he has proved that UMBA IRT can uncover novel astronomical phenomena, help guide space travel and potentially allow satellites to stay precisely and accurately on orbit.

The techniques of concrete crack detection, as well as assessments based on thermography coupled with ultrasound, have been presented in many works; however, they have generally needed an additional source of thermal infrared (TIR) radiance and have only been applied in laboratories. Considering the accessibility of thermal infrared cameras, a TIR camera (NEC F30W) was employed to detect cracking in the concrete wall of an historic house with a western architectural style in Kinmen, Taiwan, based on the TIR radiances of cracking. An operation procedure involving a series of image processing and statistical analysis processes was designed to evaluate the performance of the TIR camera in the assessment of the cracking width. This procedure using multiple measurements was implemented from March to August 2019, and the t-tests indicated that the temperature differences between the inside and outline of the concrete cracks remained insignificant as the temperature or relative humidity (RH) in the subtropical climate rose. The experimental results of the operation procedure indicated that the maximum focusing range, which is related to the size of the sensor array, and the minimum detectable crack width of a TIR camera should be 1.0 m and 6.0 mm, respectively, in order to derive a linear regression model with a determination coefficient R2 of 0.733 to estimate the cracking widths, based on the temperature gradients. The validation results showed that there was an approximate R2 value of 0.8 and a total root mean square error of ±2.5 mm between the cracking width estimations and the observations.

Dr. Alfred M. Bongiovanni is a young man who started research work as an investigator at the Marine Biological Laboratory, Woods Hole, Massachusetts, even before he received his B.S. degree from Villanova College in 1940. While at Villanova, Dr. Bongiovanni received the Kolmer Medal for Excellence in Science. In 1943 he received his M.D. from the University of Pennsylvania, following which he immediately served a 2-year tour of duty in the United States Navy. After discharge from the Navy, he filled residencies at the Children's Hospital of Philadelphia from 1947 to 1949. During the years 1949 and 1950, Dr. Bongiovanni served as Assistant Physician at the Rockefeller Institute in New York and in 1950-51 returned to the Children's Hospital of Philadelphia as Assistant Director of Clinics. In 1951 he was appointed the National Foundation of Infantile Paralysis Fellow to the Research Division of the Children's Hospital of Philadelphia. New opportunities and promotions quickly followed with an appointment as Assistant Professor of Pediatrics at Johns Hopkins in 1952; Senior Research Associate in the Pediatric Endocrine Division and Assistant Professor of Pediatrics at the University of Pennsylvania in 1954; and in 1955 Associate Professor of Pediatrics at the same university. Dr. Bongiovanni is a Diplomate of the American Board of Pediatrics and a member of the Editorial Board of the American Journal of Medical Sciences and of numerous professional societies. In 1956 Dr. Bongiovanni received the Ciba Award. Dr. Bongiovanni has been author of about 50 articles, the great majority of which are on endocrinology and at least 23 of them with Dr. Eberlein, who is the co-recipient with Dr. Bongiovanni of this Award, as a co-author.

Infrared thermography (IRT) has been widely employed to identify the defects illustrated in building facades. However, the IRT covered with a shadow is hard to be applied to determine the defects shown in the IRT. The study proposed an approach based on the multiplicated model to describe quantitively the shadow effects, and the IRT can be segmented into few classes according to the surface temperature information recorded on the IRT by employing a thermal infrared camera. The segmented results were compared with the non-destructive method (acoustic tracing) to verify the correctness and robustness of the approach. From the processed results, the proposed approach did correctly identify the defects illustrated in building facades through the IRTs were covered with shadow.

First Time

Hibernation has been proposed as a tool for human space travel. In recent years, a procedure to induce a metabolic state known as “synthetic torpor” in non-hibernating mammals was successfully developed. Synthetic torpor may not only be an efficient method to spare resources and reduce psychological problems in long-term exploratory-class missions, but may also represent a countermeasure against cosmic rays. Here we show the preliminary results from an experiment in rats exposed to ionizing radiation in normothermic conditions or synthetic torpor. Animals were irradiated with 3 Gy X-rays and organs were collected 4 h after exposure. Histological analysis of liver and testicle showed a reduced toxicity in animals irradiated in torpor compared to controls irradiated at normal temperature and metabolic activity. The expression of ataxia telangiectasia mutated (ATM) in the liver was significantly downregulated in the group of animal in synthetic torpor. In the testicle, more genes involved in the DNA damage signaling were downregulated during synthetic torpor. These data show for the first time that synthetic torpor is a radioprotector in non-hibernators, similarly to natural torpor in hibernating animals. Synthetic torpor can be an effective strategy to protect humans during long term space exploration of the solar system.

Self Organising Map

<p>The Federal Institute for Geosciences and Natural Resources has recently launched a project to characterise soils and soil patterns using smart sets of newly developed and existing technologies on regional scales. The focus lies on the combination of airborne geophysical tools like gamma ray spectrometry and remote sensing techniques such as VIS-NIR-SWIR-LWIR hyperspectral and thermal infrared imagery. In order to calibrate the measurements all given methods will be implemented on ground and on soil samples in the laboratory. Additionally, geochemical, mineralogical and physical investigations well established in soil sciences will be incorporated. The aim is to map and evaluate the physical properties acquired from drones, helicopter and satellites. Using statistical methods and means of artificial intelligence areas of homogeneous physical soil properties will be determined.  The resulting areas will be compared to soil classification maps and the distribution of soil substrates. Self organising map systems will be used for correlation of homogeneous areas and later interpretation. Major care will be taken to reduce effects from varying soil moisture and surface vegetation. The presentation will focus on ground based, airborne and space platforms and their instrumentation and current developments. Apart from off-road vehicles at least three different sets of drones will be used for detailed surveying, implementing newly developed gamma ray sensing systems, hyperspectral and thermal infrared cameras. The BGR helicopter will be equipped with a high-end gamma spectrometer and imaging hyperspectral sensors. We envisage using future hyperspectral EnMAP data to evaluate it against the helicopter results and further up- and downscaling strategies.</p>
