Preliminary analysis of a radiobiological experiment for LifeSat (1991)

With the possibility of performing radiation life science experiments on a dedicated satellite (LifeSat) in space, a combined effort in radiation physics and radiation dosimetry, in addition to radiation biology, is clearly required to ensure that meaningful biological experiments can be performed. To better understand the relationship of these disciplines, some possible LifeSat missions are examined. As a trial biological system, tumorigenesis is considered in the Harderian gland of mice, a system of sufficient radiosensitivity for which relative biological effectiveness (RBE) is well defined by laboratory experiments.
P4336Evaluation of acute psycho-physiological reaction to law enforcement operational stress and tactical driving. 20 years of prospective Italian research (2019)

Abstract Background “Fight-or-flight” reaction to perceived danger may affect operational efficiency of police officers (POs), with negative impact on public safety. Therefore, there is a growing interest for methods to investigate stress occurring during highly-demanding operations. Stress-induced reactions are studied in psychophysiology integrating multiple parameters (ECG, EEG, respiration, electrodermal activity, salivary cortisol ...), most of them unrecordable in real-world dynamic situations. Instead ECG, recordable also during physical activity, quantifies stress-related autonomic modulation (AM) through the analysis of heart rate (HR) and its variability (HRVa). We used ECG and a miniaturized wearable wireless telemetric device (mWTD) to monitor AM changes during realistic police tactical training (rPTT), police tactical driving (PTD), oleoresin capsicum exposure (OCE) and live-fire shooting competitions (LFSC). 20 years of research, aimed to understanding of mechanisms underlying human response in force-on-force scenarios and to design more efficient training methods for POs, are reported. Method We selected data of 185 healthy POs (33.6±4.4 years old) investigated during rPTT with different psycho-physiological impact. Until 2015, ECG was recorded with standard ECG-Holter, then the novel mWTD connected to a standard textile sensors garment (Nuubo) has been used featuring simultaneous recording of 3 ECG and 2 Skin potential responses (SPR) for real-time assessment of transient variation of AM with a novel fast algorithm for integration of time-variant HRV spectral parameters (HRVp) and of Root Mean Square value of the two SPR signals (SPRRMS). Results HR increment varied significantly among individuals undergoing the same tasks. Highest HR values (>180 bpm in 66%) were observed during LFSC, often associated with poor operational score. Standard short-term HRVa was inadequate to evidence short-lasting transient changes of AM response due to acute stress (dominant LF at the beginning of task and at medium workload, relative dominance of HF and inversion of LF/HF ratio at the zenith of HR, in high-stress tasks). Under OCE, 83% of POs were able to perform their tasks, despite typical physical symptoms, high HR increment (peak 161 bpm) and HRV decrement with LF prevalence. Discriminant Analysis of HRVp differentiated between physical and psychological stress (accuracy >80%). During PTD good correlation was found between stress-induced increment of SPR activity and driving demands. Conclusion The mWTD is reliable for on-duty compatible recordings and telemetric transmission of AM during highly-demanding operations of POs. Real-time calculation and monitoring of time-varying spectral HRVp with SPRRMS provide immediate multimodal information on AM response to emotional and physical stress reactions to tactical demands. Discriminant Analysis of HRVp is useful to differentiate psychological and physical stress during police operational activity.
Developments in fluidized bed conversion of solid fuels (2015)

A summary is given on the development of fluidized bed conversion (combustion and gasification) of solid fuels. First, gasification is mentioned, following the line of development from the Winkler gasifier to recent designs. The combustors were initially bubbling beds, which were found unsuitable for combustion of coal because of various drawbacks, but they proved more useful for biomass where these drawbacks were absent. Instead, circulating fluidized bed boilers became the most important coal converters, whose design now is quite mature, and presently the increments in size and efficiency are the most important development tasks. The new modifications of these conversion devices are related to CO2 capture. Proposed methods with this purpose, involving fluidized bed, are single-reactor systems like oxy-fuel combustion, and dual-reactor systems, including also indirect biomass gasifiers.
MONORADICAL REARRANGEMENT OF 1,4-BIRADICALS INVOLVED IN NORRISH TYPE II PHOTOREACTION OF METHANONAPHTHOQUINONES (1982)

Abstract Type II photoreaction of the title compound gave a cyolobutanol by cyclization, an unsaturated keto alcohol by reverse disproportionation, and a bicyclic diketone by cyclopropylcarbinyl rearrangement. Relative rates of the type II biradical reactions were estimated on the basis of the product analysis.
Hypothermia and cardiac arrest in the treatment of giant aneurysms of the cerebral circulation and hemangioblastoma of the medulla (1981)

✓ Hypothermia and elective cardiac arrest may be of benefit during surgery of some technically difficult lesions of the brain. Eight giant aneurysms and one hemangioblastoma of the medulla were operated on with no mortality, using hypothermia and cardiac arrest. All but one aneurysm were excluded from the cerebral circulation, and the hemangioblastoma appeared to be completely excised. Careful attention to clotting factors, depth of hypothermia, and time of bypass were important factors in the success of this series.
Separation of serum creatine kinase isoenzymes by ion-exchange column chromatography. (1977)

We describe a practical, technically convenient DEAE-Sephadex chromatographic column and a three-fraction salt-gradient elution procedure, with which serum creatine kinase activity is rapidly and quantitatively separated into the isoenzyme components with excellent analytical recovery of the total activity applied. The homogeneity of the isoenzyme fractions was demonstrated by electrophoresis and rechromatography. Sera assessed by the Mercer fractionation [Clin. Chem. 20, 36 (1974)] and the present procedure showed excellent agreement.
Studies on OK-432-induced antitumor activity in human peripheral blood mononuclear cells. (1992)

Antitumor activities of OK-432-stimulated peripheral blood mononuclear cells (PBMC) were examined. Killer activity against natural killer (NK) cell-sensitive K562 as well as lymphokine activated killer (LAK) cell-sensitive Daudi and PC3 target cells were detected among PBMC cultured with a low dose (0.0125-0.05 KE/ml) of OK-432. Kinetic analysis of killer activity showed that it reached a plateau level by 48 h of culture. Various freshly isolated tumor cells from oral cancer patients were also lysed by both the autologous and allogeneic OK-432-stimulated PBMC (OK-MC), suggesting that the specificity of the killer was not restricted by HLA and was thus non-specific. Fluorescence activated cell sortor (FACS) analyses showed that CD57+/CD25+ and CD16+/CD25+ cells were increased in PBMC after 48-h stimulation with OK-432. The killer activity was further augmented by the addition of rIL-2 at the time of killer assay.Tumor growth inhibitory factor (TGIF) activity, which we previously reported, was found in the culture supernatant (CSN) of OK-MC from various cancer patients. The titer of TGIF from these patients was high enough, 16-64 × of the reciprocal dilution of the CSN, which was almost equivalent to the activity from normal healthy controls.These results suggest that two kinds of antitumor activities were induced in the OK-432-stimulated PBMC in vitro, the one being cell-mediated and the other lymphokine-mediated (TGIF). OK-MC is thus supposed to be effective for adoptive immunotherapy (AIT) in oral cancer patients.
Universality, multiplicity, and the effect of iron impurities in the Belousov–Zhabotinskii reaction (1987)

In experiments on the Belousov–Zhabotinskii reaction in a flow reactor we have observed dynamical behavior that is described well by one-dimensional maps with a single maximum. A sequence of period doubling bifurcations was observed as a parameter was varied, and beyond the accumulation point for the period doubling sequence there was a sequence of periodic states that has the same symbolic dynamics as the states of the U (universal) sequence of Metropolis, Stein, and Stein (1973). However, in another experiment with malonic acid from a different vendor, we found that some states with particular symbol sequences occurred in three different parameter ranges rather than in one range as in the U sequence. Analysis of the effect of impurities in the reagents showed that some impurities (e.g., Fe3+ and esters of malonic acid) at concentrations of only a few ppm produced dramatic changes in the dynamics; such impurities are contained in commercially available malonic acid. Experiments with purified malonic acid indicate that the Fe2+/Fe3+ and Cu+/Cu2+ redox couples act as co-catalysts of the Belousov–Zhabotinskii reaction; their effect can be explained by a free radical mechanism. Other metal ions (e.g., Ni2+ and Co2+) at low concentrations have negligible effect on the dynamics. Finally, both the sequences with universal ordering and the sequences with multiplicity are described well by indented trapezoid maps of the type analyzed by Beyer, Mauldin, and Stein (1986).
Surface Forces Apparatus Measurements of Interactions between Rough and Reactive Calcite Surfaces (2018)

nm-Range forces acting between calcite surfaces in water affect macroscopic properties of carbonate rocks and calcite-based granular materials and are significantly influenced by calcite surface recrystallization. We suggest that the repulsive mechanical effects related to nm-scale surface recrystallization of calcite in water could be partially responsible for the observed decrease of cohesion in calcitic rocks saturated with water. Using the surface forces apparatus, we simultaneously followed the calcite reactivity and measured the forces in water in two surface configurations: between two rough calcite surfaces (CC) and between rough calcite and a smooth mica surface (CM). We used nm-scale rough, polycrystalline calcite films prepared by atomic layer deposition. We measured only repulsive forces in CC in CaCO<sub>3</sub>-saturated water, which was related to roughness and possibly to repulsive hydration effects. Adhesive or repulsive forces were measured in CM in CaCO<sub>3</sub>-saturated water depending on calcite roughness, and the adhesion was likely enhanced by electrostatic effects. The pull-off adhesive force in CM became stronger with time, and this increase was correlated with a decrease of roughness at contacts, the parameter which could be estimated from the measured force-distance curves. That suggested a progressive increase of real contact areas between the surfaces, caused by gradual pressure-driven deformation of calcite surface asperities during repeated loading-unloading cycles. Reactivity of calcite was affected by mass transport across nm- to μm-thick gaps between the surfaces. Major roughening was observed only for the smoothest calcite films, where gaps between two opposing surfaces were nm-thick over μm-sized areas and led to force of crystallization that could overcome confining pressures of the order of MPa. Any substantial roughening of calcite caused a significant increase of the repulsive mechanical force contribution.
Epidermolysis bullosa acquisita-mapping of antigenic determinants by an immunofluorescent technique (1986)

In a 32-year-old patient suffering from a mild form of epidermolysis bullosa acquisita, the level of the dermolytic cleavage was determined by immunofluorescent mapping of the antigenic determinants (type IV-collagen and laminin), which were found on the roof of the blister. This labelling pattern was compared with the in vivo deposit of IgG by a double immunofluorescent technique. With regard to electron microscopy, this method represents an easier and more rapid diagnostic procedure.
Knowledge gaps in the study of the impacts of elevated atmospheric CO <sub>2</sub> and other greenhouse gases on forest ecosystems. (2001)

This paper discusses some of the most pressing questions regarding the impact of elevated CO2 and greenhouse gases on forests including: the stability of long-term growth responses; impacts on wood quality; acclimation of physiological and/or growth responses, physiology, pest responses and carbon sequestration under interacting greenhouse gases; impact of elevated CO2 and of interacting greenhouse gases on antioxidant and defence systems; and the impact on community, stand and ecosystem dynamics, and on ecological processes such as nutrient and water cycling.
Evaluation of risk factors for outcome associated with adrenal gland tumors with or without invasion of the caudal vena cava and treated via adrenalectomy in dogs: 86 cases (1993–2009) (2013)

Invasion of the caudal vena cava, particularly tumor thrombus extension beyond the hepatic hilus, was associated with a higher postoperative mortality rate, but did not affect long-term prognosis in dogs undergoing adrenalectomy because of an adrenal gland tumor.

A Cavity Green's Function Boundary Element Method With Spectral Domain Acceleration for Modeling of Reverberation Chambers (2014)

A novel boundary element method approach with the rectangular cavity Green's function is presented and utilized to model reverberation chambers. Different from all other approaches that employ rectangular cavity Green's functions, the computationally expensive part of the matrix-vector product is evaluated in the spectral domain. A drastic acceleration is achieved even though the algorithm operates with excellent accuracy. The approach is validated and compared against the boundary element method with free-space Green's function. Examples demonstrate the usability of the proposed approach.

Angle gathers in wave‐equation imaging for VTI media (2009)

Angles in common‐image angle‐domain gathers refer to the scattering angle at the reflector and provide a natural access to analyzing migration velocities and amplitudes. In the case of anisotropic media, the importance of angle gathers is enhanced by the need to properly estimate multiple anisotropic parameters for a proper representation of the medium. We extract angle gathers for each downward‐continuation step from converting offset‐space‐frequency planes into angle‐space planes simultaneously with applying the imaging condition in a transversely isotropic (VTI) medium. The analytic equations, though cumbersome, are exact within the framework of the acoustic approximation. They are also easily programmable and show that angle gather mapping in the case anisotropic media differs from its isotropic counterpart, difference depending mainly on the strength of anisotropy.
Bandwidth Measurement of Multimode Fibers through System Level Bit Error Rate Testing (2011)

A new bandwidth measurement method for multimode fibers is developed through measuring bit error rate and power penalty associated with the testing system. Experimental calibration procedure and actual fiber measurement results are presented.
Cardiac arrhythmias associated with spinal cord injury (2013)

Bradycardia was commonly seen in the acute stage after SCI as well as during procedures such as penile vibro-stimulation and tracheal suction. These episodes of bradycardia were seen more often in individuals with cervical injuries. Longitudinal studies with continuous electrocardiogram recordings are needed to uncover the true relation between cardiac arrhythmias and SCI.
SIRE1, an Endogenous Retrovirus Family from Glycine max, Is Highly Homogeneous and Evolutionarily Young (2003)

SIRE1 is unusual among Ty1-copia retrotransposons in that it has an additional open reading frame with structural features similar to retroviral envelope proteins between pol and the 3' LTR. Here we report the characterization and comparison of eight different SIRE1 elements derived from a soybean genomic library, as well as SIRE1 reverse transcriptases from Glycine soja. The DNA sequences of the eight SIRE1 elements are highly homogeneous and share greater than 95% nucleotide identity. Partial sequences obtained from BAC ends are similarly conserved. Phylogenetic analyses resolve two closely related SIRE1 lineages, and nucleotide changes within and between SIRE1 lineages have occurred to preserve function. Both the gag and the env-like genes are evolving under similar levels of functional constraint. Considerable sequence heterogeneity in the form of short duplications was found within the LTRs and in the region between the envelope-like ORF and the 3' LTR. These duplications are suggestive of slippage by reverse transcriptase during replication. Sequence identity between LTRs of individual insertions suggests that they transposed within the past 70,000 years. Two of 10 SIRE1 insertions examined abut Ty3-gypsy retroelements. Since the soybean genome harbors more than 1,000 SIRE1 insertions, the collective data suggest that SIRE1 has undergone a very recent and robust amplification in soybean.
Modelling and control of three-phase grid-connected power supply with small DC-link capacitor for electrolysers (2016)

These days electrolyzers are becoming more and more interesting due to the high demand for energy storage in form of hydrogen for renewable power generation using fuel cells. The design of a power supply for such a system is complex especially when the DC-link capacitance is reduced. By substituting the complex switching model of the power supply with a simplified one, the system dynamics can be better observed. The resonances caused by the small DC link capacitor and grid side inductance can be easier analyzed. A feed forward compensation method is proposed based on the simplified model of the system in order to minimize the effects of the DC link voltage ripple on the load voltage and current. The proposed method uses Frequency-Locked Loop (FLL) for estimating the fundamental component of the DC-link voltage ripple. Based on the reconstructed rectifier component a new feed-forward compensation signal is created, canceling in such a way the resonance introduced by the grid inductance and the DC-link capacitor from the feed-forward loop. The theoretical work has been validated through experiments on a 5 kW DC power supply used for electrolyser application.
