Hydrogen absorption/desorption properties of light metal hydroxide systems

In light metal hydroxide systems, hydrogen desorption generally occurs in exothermic reactions; therefore, these reactions are irreversible in principle. However, according to theoretical calculation of thermodynamics, some of these systems can desorb hydrogen in endothermic reactions. In this research, several hydroxide systems were studied to clarify the reversibility of these systems. Six types of hydroxide systems (XH + Y(OH)n, X: Li, Na, Y: Li, Na, Mg) were prepared by ball‐milling, then the desorption properties of these systems were evaluated. As a result, NaH + LiOH and NaH + NaOH systems desorbed hydrogen in endothermic reactions. Also, NaH + NaOH system absorbed hydrogen almost 100% reversibly under 300°C and 1.0 MPa H2 pressure. The reversibility in NaH + LiOH system was not accomplished in our experimental condition, because high pressure of GPa order is required for the rehydrogenation. In order to modify the desorption kinetics, we added KH catalyst to NaH + LiOH and NaH + NaOH systems. The hydrogen desorption temperature of the two systems was decreased by addition of 1 mol% of KH. The catalytic effect on hydrogen desorption properties was sustained even after the rehydrogenation of KH‐added NaH + NaOH system.

Multi-angle polarimetric (MAP) imaging of Earth scenes can be used for the retrieval of microphysical and optical parameters of aerosols and clouds. The Airborne Hyper-Angular Rainbow Polarimeter (AirHARP) is an aircraft MAP 15 instrument with the hyper-angular imaging capability of 60 along-track viewing angles at 670 nm, and 20 along-track viewing angles at other wavelengths 440, 550, 870 nm across the full 114 ̊ (94 ̊) along-track (cross-track) field-of-view. Here we report the retrieval of aerosol properties using the Generalized Retrieval of Aerosols and Surface Properties (GRASP) algorithm applied to AirHARP observations collected during the NASA Aerosol Characterization from Polarimeter and Lidar (ACEPOL) campaign in October – November 2017. The retrieved aerosol properties include spherical fraction (SF), aerosol 20 volumecolumn concentration in multiple size distribution modes, and with sufficient aerosol loading, complex aerosol refractive index. From these primary retrievals, we derive aerosol optical depth (AOD), Angstrom exponent (AE), and single scattering albedo (SSA). AOD retrieved from AirHARP measurements are compared with the High Spectral Resolution LiDAR-2 (HSRL2) AOD measurements at 532 nm and validated with measurements from collocated Aerosol Robotic NETwork (AERONET) stations. A good correlationagreement with HSRL2 (ρ = 0.940, |BIAS| = 0.062) and AERONET AOD 25 (0.013 ≤, Mean Absolute Error (MAE) ≤ 0.017,= 0.122) and AERONET AOD (0.010 ≤ MAE ≤ 0.013015, 0.002 ≤ |BIAS| ≤ 0.017009) measurements is observed for the collocated points. There was a mismatch between the HSRL2 and AirHARP retrieved AOD for the pixels close to the forest fire smoke source and to the edges of the plume due to spatial mismatch in the sampling. This resulted in a higher BIAS and MAE for the HSRL2 AOD comparison. For the case of AERONET AOD comparison, two different approaches are used in the GRASP retrievals, and the simplified aerosol component-based 30 GRASP/Models kernel which retrieves fewer number of aerosol parameter performed well compared to a more generous GRASP/Five mode approach in the low aerosol loading cases. Forest fire smoke intercepted during ACEPOL provided a situation with homogenous plume and sufficient aerosol loading to retrieve the real part of the refractive index (RRI) of 1.55
A Comparative Study of Posterior Approach versus Lateral Approach in Surgical Management of Intra-capsular Neck Femur Fractures

Aims and Objective: The present study was undertaken to evaluate and compared relevant early surgical complications rates after posterior and lateral approach. Methods: A total 80 patients of either sex, age between 50-80 years with intracapsular neck femur fracture were operated with hemiarthroplasty. Patients were divided in two equal groups i.e. group A and B operated with posterior and lateral approach respectively. Several variables including age, sex, operative time, blood loss, early surgical and post-operative complications, post-operative care, hip function and final outcome measures were noted and compared between two groups. Results: The mean age of patients was 64.30 5.39 years in group A and 65.85 5.64 years in group B with female to male ratio was 1.6:1 for group A and 1.4:1 for group B. Operating time for group A and for group B was 48.435. 38 and 47.507.59 minutes respectively. Mean intraoperative blood loss was 144.7517. 68 ml in group A and 148.3815. 03 ml in group B. The most common complication in both the groups was infection and rate in group A was 17.50% and in group B was 12.50%. Posterior approach carries an increased risk of prosthetic dislocation as compared to lateral approach. There was no intraoperative mortality seen in follow up period. The rate of secondary procedures was high with posterior approach (12.5%) as compared to lateral approach (7.5%). The average Harris Hip Score was 85.62% in group A and 83.40% in group B. Conclusion: The rate of early surgical complications and outcome measures after posterior and lateral approaches is not significantly different. A larger randomized trial or may be a multicentre trial can further improve the interpretation of the results.
Vibration Suppression of a Micropipe Conveying Fluid via Sliding Mode Technique

In this article, derivation of a nonlinear model and nonlinear controller design for a micropipe conveying fluid, which is excited with a piezoelectric actuator, are accomplished. The governing equations are derived by using Hamilton’s principle. The difference between the equations in micro-scales and macro-scales is established by using the modified couple stress theory. Unlike the classical Timoshenko beam theory, this new theorem includes a material length scale parameter which could help capturing the size effect. In addition, for thin members, so long as the deformation in the order of thickness, they do not remain in the elastic zone. Therefore, the linear theorem produces error in predicting in-plane movement of the member. In this way, the nonlinear terms are considered in the equations by applying mid-plane stretching theory. After this derivation, a frequency analysis is performed on the model. In addition, the effective parameters on the peak value of the response are studied as well. Finally, a sliding mode controller for the input voltage of the system is designed. It has been observed that by using this type of nonlinear controller, the behavior of the system could be improved significantly.
Micromechanics of plasticity of Zr-2.5%Nb alloy

Zirconium alloys are used in many thermal neutron fission reactors because of their very low neutron interaction cross-sections along with their excellent mechanical strength and corrosion resistance. Numerous experiments have been conducted on these alloys at the bulk scale to determine their mechanical properties. Recent advancements in micromechanical testing make it easier to study site specific mechanical properties for micron or submicron sized samples. Understanding the mechanical response of such small volumes of material is extremely important for developing accurate models to predict the ductile fracture toughness of these in-reactor materials. Pressure tubes made of Zr2.5%Nb alloys are integral part of the CANDU reactors as they carry the fissile uranium fuel bundles and also transport the heavy water coolant to the core. During services in the reactor the insides surface of these tubes can develop micron sized scratches due to repeated sliding motion of the fuel bundles. In order to properly assess the impact of these flaws in the long run, good understanding of localized plastic deformation in very small regions near these surface scratches is important. Uniaxial compression tests were performed on 1μm diameter micro-pillars fabricated from the axial normal (AN) and transverse normal (TN) planes of an extruded and 22% cold-drawn Zr-2.5%Nb CANDU pressure tube to assess the effect of crystallographic orientations, α/β interfaces, irradiation temperature, and deformation temperature on the mechanical anisotropy and active plastic deformation mechanisms. Some of the micro-pillars were implanted with 8.5MeV Zr ions at room temperature and 300°C to simulate the effect of neutron irradiation. For the non-implanted αZr pillars compressed at 25°C the flow stress at 10% strain, σε=10% was significantly higher than that reported for larger diameter
Quantitative and molecular differences distinguish adult human medullary and extramedullary haematopoietic stem and progenitor cell landscapes

In adults, the bone marrow (BM) is the main site of haematopoietic stem and progenitor cells (HSPCs) maintenance and differentiation. It is known that other anatomical sites can contribute significantly to blood production under stress conditions. However limited tissue availability restricts our knowledge on the cellular, molecular and functional composition of extramedullary HSPC pools in humans at steady state or under stress. Here we describe the landscape of human HSPC differentiation across the three major haematopoietic anatomical sites: BM, spleen and peripheral blood (PB), using matched tissues isolated from the same individuals. Single cell RNA-seq of 30,000 HSPCs and 700 phenotypic haematopoietic stem cells and multipotent progenitors (HSC/MPP) demonstrates significantly different dynamics of haematopoiesis between BM and extramedullary tissues. Lineage-committed progenitors of spleen and PB do not actively divide, whereas BM is the primary site of progenitor proliferation. The balance of differentiation in spleen and PB is skewed towards the lymphoid and erythroid lineages, whereas in BM it is tilted towards megakaryocytic and myeloid progenitors. Extramedullary tissues also harbour a molecularly defined subset of HSC/MPP not found in the BM, which is marked by a specific acto-myosin cytoskeletal signature and transcriptional priming for division and lineage differentiation. Collectively, our findings define a unique cellular and molecular structure of the haematopoietic landscape in extramedullary organs, positioned for rapid lineage-primed demand-adapted haematopoiesis. These data also provide a framework for better understanding of human extramedullary haematopoiesis in health and disease.

Missing the mark on malaria?A quantitative study of the effects of the 2007 Malawian malaria treatment change on under-five mortality

Malaria continues to impose a high burden on the Malawian population, in particular on children under the age of five, accounting for about 20 percent of all deaths among under-fives in 2000. In an effort to curb these numbers, the Malawian government launched a new Malaria Strategic Plan in 2005, aimed at reducing malaria morbidity and mortality. As part of this policy the treatment regimen for malaria was changed in accordance to the World Health Organization recommendations in December 2007. This paper aims to analyze the consequences of this change by examining the effects of the new treatment on the group most severely affected by malaria – children under the age of five. Using a Difference-in-difference method I estimate the impact on under-five mortality by combining data on in-patient malaria mortality among under-fives, and data from the 2010 Demographic and Health Survey. My strategy generated results that show no significant effect of the new and better treatment on the considered age group. Rather, my findings seem to counter previous theories on higher income and educational levels reducing child mortality, suggesting further studies in the particular context are needed.
Comprehensive identification of HSP70/HSC70 Chaperone Clients in Human Cells

The HSP70 family of chaperones are the front-line of protection from stress-induced misfolding and aggregation of polypeptides in most organisms and are responsible for promoting the stability, folding, and degradation of clients to maintain cellular protein homeostasis. Here we demonstrate quantitative identification of HSP70 and HSC70 clients using an ubiquitin-mediated proximity tagging strategy and show that, despite their high degree of similarity, these enzymes have largely non-overlapping specificities. Both proteins show a preference for association with newly synthesized polypeptides but each responds differently to changes in the stoichiometry of proteins in obligate multi-subunit complexes. In addition, expression of an ALS-associated SOD1 mutant protein induces changes in HSP70 and HSC70 client association and aggregation toward polypeptides with predicted disorder, indicating that there are global effects from a single misfolded protein that extend to many clients within chaperone networks. Together these findings show that the ubiquitin-mediated UBAIT fusion system can efficiently isolate the complex interactome of HSP chaperone family proteins under normal and stress conditions.
Does maturity signals high risk and high return?

The objective of this study is to examine the interaction between firm maturity and firm growth opportunities over risk and its impact on returns. This study uses 135 firms listed in Indonesia Stock Exchange during 2010 to 2016 as sample which gives 945 as total observed data. This study conducts path analysis in term for hypothesis testing and finds that firm maturity has significant role to increase the risk which gives impact on increasing the returns. In context of Indonesian firms, the findings imply that mature firms will have higher risk and higher returns.
The Fate of MTBE and BTEX in Constructed Wetlands

Hydrocarbon contamination of water resources is a global issue. These compounds are generated and discharged into the environment in industrial areas from chemical and petrochemical plants, oil refineries, power plants, and so forth. Fuel hydrocarbons, namely, BTEX (benzene, toluene, ethylbenzene, and xylenes) and MTBE (methyl tert-butyl ether), are commonly found in groundwater, posing environmental and health risks to humans and ecosystems. Nature-based technologies represent an alternative solution, providing high efficiency, an environmentally friendly character, simple operation, and cost efficiency, which are characteristics particularly desired by the international petroleum industry. This article discusses the use of the green technology of constructed wetlands to remediate water polluted with hydrocarbons. Although the number of related international experiences and studies is limited, the article presents the latest developments of wetland technology for the removal of MTBE and benzene-BTEX. The discussion includes the overall efficiency of the different wetland types that have been tested and used, the main transformation and removal processes that regulate the fate of BTEX and MTBE in constructed wetlands, and the potential for future investigations.
Nonthermal Laser Combined With a Lymph Drainage System for Noninvasive Body Circumference Reduction

A nonthermal laser device is approved for noninvasive body circumference reduction and temporary improvement in the appearance of cellulite. Another noninvasive device based on the principle of manual lymph drainage is approved for body circumference reduction and improving the appearance of cellulite. This pilot study evaluated the effectiveness of combining these treatments for reducing body circumference. Healthy men and women (N = 27), 22 to 70 years of age with a body mass index of 25 to 40 kg/m2, inclusive, seeking to improve the appearance of their waist, hips, and upper abdomen, were enrolled. The laser device consists of 6 independent, variable frequency lasers emitting a 532-nm green light with a mean power output of 17 mW (Erchonia Verjú Laser System; Erchonia Corporation, Melbourne, Florida). The lymphatic drainage system is a pressure therapy intended for body contouring and cellulite reduction applications and for reducing edema (Green PRESS 8 Lymphatic Drainage System; Iskra Medical, Podnart, Slovenia). Participants received 12 treatments, one every 3 to 4 days over a 6-week period. Each session included a 30-minute nonthermal laser treatment (15 minutes each to front and back) followed by a 30-minute treatment with the lymphatic drainage system. To evaluate comparability of the combined devices treatment with the nonthermal laser treatment, individual study success for the nonthermal laser alone was a 3.0-inch (7.62 cm) decrease in combined baseline hips, waist, and upper abdomen circumference at the end of the study. A 50% increase in combined hips-waist-upper abdomen circumference measurement following combined treatments was considered a clinically meaningful improvement over the use of nonthermal laser alone. Individual study success was achieved by 17 participants (63.0%), exceeding the preestablished overall study success criteria of 60% in comparison with nonthermal laser treatment alone. The mean (SD) combined body circumference decreased from 112.3 (13.7) inches at baseline to 108.5 (13.8) inches at the end of the study, a mean decrease of 3.9 (2.7) inches (P < .0001). One-way analysis of variance tests for changes in total body circumference measures at weeks 4, 8, and 12 were significantly less than baseline (for each, P < .01); however, the study failed to achieve a 50% decrease in combined hips-waist-upper abdomen circumference measurement following application of combined treatments versus nonthermal laser alone. Additional treatment with a manual lymphatic drainage system does not improve the effectiveness of a nonthermal 532-nm green laser for reducing hips, waist, and upper abdomen circumference.
Effectiveness of Nutrition Education for Elementary School Children Based on the Theory of Planned Behavior

School children are facing rapid developments both mentally and physically – thus, good nutrition is very important in this phase of life to ensure their normal and healthy growth process. The current study aimed at examining the effect of peers education based on the Theory of Planned Behavior (TPB) on improving elementary female students’ behavioral nutrition in Chabahar, Iran, in 2017. In this quasi-experimental study, a total of 160 female elementary fourth-grade students were sampled using multi-stage random sampling and randomly divided into two groups of control and intervention. Data were collected using a researcher-made questionnaire with confirmed validity and reliability. The questionnaire consisted of two parts, the first part consisting of demographic and awareness questions and the second part related to the constructs of the theory of planned behavior. The educational intervention was performed on the intervention group using question and answer method by trained peers (two 45-minute training session). Two months after the intervention, the same questionnaire was completed for the post-test. Data were analyzed by paired and independent t-test, Spearman correlation and regression with SPSS 16 software. The cognitive skills increased significantly from 8.01 to 9.95 after the intervention.

Keyframe‐based thermal–inertial odometry

Autonomous navigation of microaerial vehicles in environments that are simultaneously GPS‐denied and visually degraded, and especially in the dark, texture‐less and dust‐ or smoke‐filled settings, is rendered particularly hard. However, a potential solution arises if such aerial robots are equipped with long wave infrared thermal vision systems that are unaffected by darkness and can penetrate many types of obscurants. In response to this fact, this study proposes a keyframe‐based thermal–inertial odometry estimation framework tailored to the exact data and concepts of operation of thermal cameras. The front‐end component of the proposed solution utilizes full radiometric data to establish reliable correspondences between thermal images, as opposed to operating on rescaled data as previous efforts have presented. In parallel, taking advantage of a keyframe‐based optimization back‐end the proposed method is suitable for handling periods of data interruption which are commonly present in thermal cameras, while it also ensures the joint optimization of reprojection errors of 3D landmarks and inertial measurement errors. The developed framework was verified with respect to its resilience, performance, and ability to enable autonomous navigation in an extensive set of experimental studies including multiple field deployments in severely degraded, dark, and obscurants‐filled underground mines.
