Global Drivers and Transport Mechanisms of Lunar Rockfalls

The long‐ and short‐term drivers and transport mechanisms of lunar rockfalls are currently not well understood, but could provide valuable information about the geologic processes that still shape the surface of the Moon today. Here, we compare the global distribution of rockfalls with relevant geophysical data, such as seismic, topographic, thermal, gravity anomaly, and tidal displacement data sets. Rockfalls appear to predominantly occur (a) on equator‐facing slopes and thus in regions with large thermal amplitudes, (b) on slope angles well above‐average (Δ ∼ 10°), and (c) in regions with above‐average rock abundance. We do not observe a qualitatively or statistically relevant relation between rockfall abundance, monitored Apollo‐era shallow seismic activity, and the distribution of visible tectogenetic features. Informed by our global analysis, we conduct a targeted, in‐depth study of 687 rockfall boulders and trajectories in 13 sites across the Moon, including 7 craters, 2 volcanic vents, 2 tectonic structures, and 2 unclassified geomorphic regions. We identify four different source region types, where the type appears to control the occurrence of rockfalls. The source region type in turn is controlled by surface age rather than geomorphic context. We find that rockfall trajectories are mainly controlled by the trigger energy and the geometry of the slope. Our results suggest that erratic small‐scale impacts (mainly in old, Imbrian‐Nectarian, shallow terranes), aided by solar‐induced thermal fatigue of fractured bedrock (mainly in young, Copernican‐Eratosthenian steep terranes), were the dominant, global‐scale long‐ and short‐term drivers of rockfalls in the Moon's recent geologic past.
Stormwater pond sediments and water—characterization and assessment

Stormwater pond sediments were collected from four stormwater ponds in Sweden and analysed for heavy metal, water and organic material content. The sediment characteristics were evaluated, and differences between and within the ponds are presented and discussed. An assessment of the water and sediment quality was also carried out. The results show that the metal content does not vary much between or within the ponds. The copper content is significantly higher than reported in earlier studies and copper is the critical metal for the ecological status of the ponds. The quality of pond sediment is comparable with sewage sludge or urban stream sediments.
Prevalence and Distribution of Unerupted/Impacted Teeth Among Individuals 18-25 Years of Age Visiting Outpatient Department of Private Dental College and Hospital in Chennai, India

The term unerupted / impacted teeth defines a failure of the tooth to erupt within the expected time into the dental arch. Impaction is a common dental anomaly where the tooth has not erupted beyond the eruption period. The incidence of unerupted / impacted teeth differs among different populations and in different ethnic groups. The aim of this study was to assess the prevalence of unerupted/ impacted teeth among patients of 18-25 years of age visiting Private Dental college and hospital, Chennai. This is a descriptive study which is performed under a university setting where all the patients reported to Private Dental college and hospital, chennai. The data was collected by reviewing patients records and analysed the data of 86000 patients who underwent extraction between June 2019 to March 2020. The population size of the study was found to be n=296 . Data was collected , tabulated ,statistical analysis was done by SPSS – IBM. ( Statistical Package for Social Studies ) . From the statistical analysis, it is observed that the total number of extraction done between 18-25 years was found to be n=7339 (96%) out of which only n= 295 (4%) was found with an incidence of impaction. The overall prevalence of unerupted/ impacted teeth were higher in males(55.74%) predominantly between the age groups of 24 years (18.8%) and was commonly reported to third molars (41.9%) . Within the limitation of the current study, it is found that unerupted / impacted teeth are more common among 24 years of age with male predilection with higher incidence of mandibular molars.
The role of personality in COVID-19 related perceptions, evaluations, and behaviors: Findings across five samples, nine traits, and 17 criteria

Individuals and institutions around the world have been affected by the Coronavirus Disease 2019 (COVID-19). Herein, we investigate the role of basic (Big Five and HEXACO) and specific (Dark Factor of Personality, Narcissistic Rivalry and Admiration) personality traits for 17 criteria related to COVID-19, grouped into (i) personal perceptions in terms of risks and worries about the disease, (ii) behavioral adjustments in terms of following health recommendations and hoarding, and (iii) societal evaluations in terms of the appropriateness of different measures and feelings of social cohesion. (Internal) Meta-analytic results across five samples from two countries (overall N = 19,718) show—next to gender and age effects—the importance of several traits, including Emotionality/Neuroticism for personal perceptions and anti- or prosocial traits for behavior in line with health recommendations. The investigation highlights the importance of individual differences in uncertain and changing situations in general and during the COVID-19 pandemic in particular.
Fatigue Resistance: Design Considerations

Contrary to the general conception of adding weight for fatigue resistance it is sometimes possible to reduce the fatigue hazard by removing weight. The theory of having bearing area, tear‐out area, and tension area sufficient to develop the full shear strength of a rivet is not necessarily sound when fatigue life is considered. Accordingly, marked improvements in fatigue resistance can be achieved by reducing the underlying areas to such an extent that they are incapable of inducing loads causing fatigue failures of the main structure. Results of tests involving fatigue failure are given, and seven basic considerations in the design of fatigue resistant structures are listed.
Yeasts are able to inhibit growth of disease-associated fungi

Background Fungal sepsis is often caused by non-albicans Candida or other species. These disease-associated species have strong virulence and often show resistance to the commonly used antifungal treatments. Therefore, finding new inhibitory agents nowadays is increasingly urgent.Results Our screening revealed that although the pathogenic fungi were much more tolerant to yeast-produced bioactive agents than the non-disease-associated yeasts, growth of Kodamaea ohmeri and Candida tropicalis could be inhibited by Metschnikowia andauensis , while Cryptococcus albidus can be controlled by Pichia anomala and Candida tropicalis. The size of the inhibitory zone formed by yeasts was depended on media, pH and temperature. However, extensive studies were carried out, we failed to find inhibitory yeast against Pichia kudriavzevii, suggesting that it must have high natural resistance.Conclusions Certain yeast species can contribute to the future solutions of problems caused by fungal resistance and can be good candidates for finding new bioactive agents which inhibit growth of disease-associated fungi.
A robust damping controller for power systems using linear matrix inequalities

This paper presents the application of a linear matrix inequality tuning approach for the design of remote feedback controllers for power systems. In particular, the determined controllers are both robust and optimal for a wide range of operating conditions. This duality is assured through the application of the proposed tuning process. The controllers presented in this paper were conceived for and tested on a 4-machine test power system with regard to their ability to damp the inter-area oscillation present in the test system and to allow an increase in tie-line power flow without a loss of stability.
Cognitive Work Analysis: Coping with Complexity

either sits beside it or directly above it. Illustrations and diagrams are accompanied by just enough descriptive text that is distinguished from the main body of text by the use of positioning, boxing and shading. The author uses his own advice so well that there is no confusion. At intervals the author makes asides which offer added information on a point as well as, in some cases, an additional reference which could prove to be helpful. Again, the asides are well positioned and appear as logical inclusions. The author aims to enhance the skills of the designer by providing visual analytic tools derived from an up-to-date understanding of human perception. I feel that any designer who reads this book will have a clear understanding of how to make their designs successful. The author discusses what could be quite complex subjects in straightforward terms making it easy to follow and understand. Although it deals with what might usually be contained within academic textbooks he does not present it in academic language. Instead, the text behaves like a relaxed conversation between the author and reader. It takes the form of imparting interesting information rather than a lecture. This book worked because it got straight to the point, it cut out all the flannel and it laid out the information and illustrations in a logical format. Any designer who reads this book will know exactly what they need to do.
Long-Term Behavior of Posttensioned Timber Connections

AbstractTests regarding the long-term behavior of posttensioned timber connections have been performed at the ETH in Zurich. The aim of these tests is to estimate the loss in tendon force that can be expected during the lifetime of a structure. Several posttensioned beam and beam-column timber specimens exposed to controlled and uncontrolled environmental conditions and loaded only with the axial prestressing force have been monitored for more than one year. The force in the tendon was measured together with the strains in the specimens and temperature and relative humidity in the testing environment. Creep tests performed on small glulam timber blocks loaded in compression have been started as well. The estimated creep coefficients parallel and perpendicular to the grain are used to calculate the losses with an analytical model for the larger posttensioned specimens. A prestressing loss in the range of 5–10%, depending on the geometrical properties and environmental conditions, has been found at the end .
Comparison Between Numerical and Experimental Temperature Distributions in a Small Data Center Test Cell

Information Technology equipment is continuing to increase in power, leading to significant challenges from the room air conditioning perspective. Numerical models are the dominant techniques for designing new data centers and optimizing existing ones. It is thus critical to understand the inherent error in the model prediction of flow and temperature distributions in the data center, with emphasis on the vicinity of the server rack. This study uses a simulated server rack in a small room where detailed temperature (3D), flow, and power measurements were carried out for a single scenario under steady state conditions. A numerical model was constructed to represent the data center cell for this case. Model results were then compared with three dimensional experimentally obtained temperature maps and the discrepancy between the two was quantified as an error in temperature. The difference between test data and model results was found to be the highest in the exhaust air path from the rear of the simulated server rack to the inlet of the air conditioning unit. The dominant sources of error are likely to be in the use of the standard k-e turbulence model, and the simplistic rack representation in which rack exhaust airflow is assumed uniform. Both modeling limitations tend to pronounce hot and cold spots and inhibit the mixing of hot and cold air streams within the data center. This is the first study on comparison between three dimensional temperature distributions obtained via modeling and from actual data collection.Copyright © 2007 by ASME
Design, performance and application of the Vernier resolver

The Vernier Resolver is a precision angle transducer which, from the stand-point of performance, resembles a geared up synchro resolver, except that the step-up ratio between the mechanical angle and the electrical signal is obtained electrically. Vernier resolvers with step up ratios of 26, 27, 32 and 33 have been designed and built. The unit is a reluctance type, variable coupling transformer. By placing all windings on the stator, sliding contacts are eliminated. Both the stator and the rotor are laminated. Because of the averaging effect inherent in a laminated construction, the accuracy of the unit exceeds by many times the machining accuracy. The performance of present experimental units is characterized by a repeatability of better than ±3 seconds of shaft angle, and a standard deviation error over one full revolution of less than 10 seconds of arc.
Employing neural networks to assist negotiating intelligent agents

Artificial intelligence is one of the various disciplines that need to be employed towards the vision of ambient intelligence. Mobile intelligent agents introduce a powerful technology that may assist the market penetration of services and products offered online in intelligent environments. Such agents have the potential to improve the efficiency, proactive behaviour and performance of computing and communication systems in such domains. In this framework, the design and evaluation of agents responsible for handling automated negotiations on behalf of their human or corporate owners is a challenging research field. In this paper these agents are enhanced with learning techniques, in order to better simulate the human intelligence and increase the profits of their owners. As mobile agents have reduced processing capabilities and may need to migrate to foreign network nodes, the learning mechanisms they employ should require minimal resources and be computationally efficient. The proposed learning technique is based on a specially designed neural network (NN), is quite lightweight, and is appropriate for agents that represent clients in automated negotiations in intelligent environments. Exploited by agents that use a fair relative tit-for-tat negotiation strategy, it aims to increase the ratio of successful negotiations and maximize the utility of the client. The designed NN-assisted negotiation strategy has been empirically evaluated via numerous experiments under various conditions
Non-intrusive efficiency estimation method for energy auditing and management of in-service induction motor using bacterial foraging algorithm

Accurate efficiency estimation of in-service motor is crucial in industries for energy auditing and management. The method defined in IEEE Standard 112 cannot be used for in-service motors, because it disrupts the production process. This study presents a non-intrusive method for in-service motor efficiency estimation based on the bacterial foraging (BF) algorithm. The proposed method relies on measuring the stator current, stator voltage, input power, stator resistance and rotor speed of the in-service motor. The BF algorithm is used for evaluating the equivalent circuit parameters of the motor instead of using the no-load and locked-rotor tests. The efficiency is then estimated using a modified motor model. The proposed method has been tested on a 5 hp motor directly supplied by the grid and the results are compared with those obtained by particle swarm optimisation method, immune algorithm method, ant colony optimisation method, torque gauge method, equivalent circuit method, slip method, current method and segregated loss method. The results demonstrate that the proposed method can estimate motor efficiencies accurately and speedily. Hence, the method is suitable for conducting energy audits and management of the motor to predict cost savings and payback, to assist decisions concerning the investment of an energy efficient motor and also to integrate in an online monitoring system.
More than a survey: an interdisciplinary post-occupancy tracking of BER schools

In February 2009, the Australian Government announced the $16.2b Building the Education Revolution (BER) as part of an economic stimulus package. In the context of a global financial crisis, the Government called for ‘shovel ready’ projects requiring state education departments to develop template designs to speed the delivery process. Three years later, new facilities have been completed in over 1100 government schools in Victoria (DEECD, 2012). This article outlines research by an interdisciplinary team to track the early occupation of a template design used in Victoria. The design template was unusual: it enabled schools to continue using traditional classroom teaching or to slide open walls to form larger neighbourhoods suitable for team teaching. Our research linked different methodological frameworks to undertake post-occupancy evaluation (POE) of the new spaces. POE strategies are often driven by construction and project management perspectives rather than focus on organizational issues and user behaviour.
A review on strategic capacity planning for the semiconductor manufacturing industry

Due to the high capital investment cost in the semiconductor manufacturing industry, strategic capacity planning plays an important role in improving business performance. The reasons that make these problems especially difficult are: the complex fabrication process, rapid changes in technology and products, the long lead time and the high cost of capacity increment, and the high uncertain demand and capacity. Hence, a review of the existing solutions to capacity planning to cope with these difficulties is important for developing new methodologies and practices. In this paper, we provide a review of the current research and fundamental methods in strategic capacity planning, identify emerging methods for capacity planning, and take an in-depth look at future research interests.

Numerical System For Infrared Scanners And Application To The Subsurface Control Of Materials By Photothermal Radiometry

Non-destructive testing (NDT) of materials can be achieved via proper photonic excitation and radiometric monitoring of the induced thermal changes. The theoretical support for this photothermal conversion in bi-layered materials is proposed, single-pulse and periodically modulated fluxes being considered. Some practical proposals are derived concerning the various aims of NDT: coatings thickness measurements, detection of defective bondings or delaminations, measurements of contact resistances between two layers. Measurements performed with a commercially available infra-red scanner and a digital data acquisition and processing system are reported.
TESTE DE GERMINAÇÃO DE SEMENTES DE Peltophorum dubium (SPRENGEL) TAUBERT - FABACEAE

Germination test for Peltophorum dubium (Sprengel) Taubert seeds - Fabaceae. With the perspective of evaluating the influences of different temperatures and substrates for testing the germination of canafistula seeds, temperatures of 25, 20/30 (8/16 h) and 30 °C and substrates on sand, paper and roll were tested. The experiment was produced entirely by tracing the factorial system. The three lots utilized were collected in Lavras (MG) and in Lins (SP). Before the germination tests were installed, the seeds were immersed in hot water (95 °C) and left to rest in the same water, without heat, for 24 hours. The temperature of 30 °C and substrate of paper roll presented the largest as well as the fastest germination of canafistula seeds.
An Innovative Vertical Axis Current Turbine Design for Low Current Speed

This article presents the new innovative concept for optimal design of Vertical Axis Current Turbines (VACT) applicable in low current speed which is being increasingly used to harness kinetic energy of water and convert it into other useful forms of energy as a clean and renewable energy. Widespread commercial acceptability of these turbo machines depends upon their efficiency. This largely depends upon the geometric features of the hydro turbines such as operation of designed system, joints, number and shape of blades and etc. The concept of VACT was proposed to provide a solution for the case of low current force inflow to vertical axis turbines. VACT has four suitable blades with flexible hinge joint to guide the water in come to reduce the drag force, light shaft and arms with stiff metal to make rigid and strong structure. The current study discusses the components of VAC turbine, rigidity of structure, performance, executive concept, efficiency, material, gearbox, environmental impacts and prevention of water corrosion. The new proposed innovative concept of VACT has flexible hinge connection for changing the blades directions automatically to reduce hydrodynamic drag and increase the hydrodynamic pressure to rotate the main shaft and enhance the efficiency as well. Main shaft connected to epicyclical gearbox to provide the higher torque for maximum electric power generation.
Misuse of Diagnostic Aids in Process Control: The Effects of Automation Misses on Complacency and Automation Bias

The effects of misses of an automated alarm and fault diagnosis system on different manifestations of automation misuse were examined. 24 participants operated a complex multi-task process control simulation. During training, they either experienced automation misses or were only informed that failures might occur. The experience of misses reduced complacency towards the alarm function of the decision aid as well as omission errors but did neither affect complacency towards the aid's diagnostic function nor commission errors. Implications of this specific effect of automation misses for the design of training measures as well as the theoretical understanding of automation misuse are discussed.
The influence of contextual elements, actors’ frames of reference, and technology on the adoption and use of ICT in construction projects: a Swedish case study

In contemporary research on construction‐related ICT (information communication technologies), little distinction is made between the use of ICT in permanent line organizations and its use in temporary organizations (for example, in building and construction projects). This paper makes that distinction. The aim is to understand how the interplay among contextual elements, actors’ frames of reference, and the ICT itself, influences the adoption and use of ICT in a building and construction project. This will be done through a description and analysis of a case study of ICT use in a major Swedish construction company. It is concluded that the well‐defined duration of the temporary organization (the construction project) stands in sharp contrast to the generally indefinite duration of ICT‐mediated change processes. However, by analysing the ICT application to be implemented, it can be revealed whether it can be ‘ready packed’ for, or delimited to, certain processes in order to achieve immediate benefits. When implementing more encompassing ICT applications, the challenge for the company is to find alternative ways of implementation in the project‐based organization and of creating alternative spaces for innovation and renewal where new ICT can be tested and experimented with.
