Résumé :

The present research on efficacy of botanicals against pulse beetle in stored chickpea was conducted under laboratory conditions at Department of Entomology, SHUATS, Prayagraj, India during 2020-2021. The experiment was carried in the Completely Randomized Design with twelve treatments (Neem oil, Castor oil, Pungam oil and plant powders neem leaf powder, neem seed kernel powder, Vasambu rhizome powder, Turmeric powder, Custard apple leaf powder, Eucalyptus leaf powder, Lantana camara leaf powder, Notchi leaf powder, insecticide (Rynaxypyr) and untreated control. The results were evaluated on the basis of adult mortality, weight loss and Feeding Detterent Index. Vasambu rhizome powder, Neem oil, Castor oil, and Pungam oil were discovered to be the most successful treatments, demonstrating 100% adult mortality, negligible weight loss, and 100% Feeding Detterent Index.The effectiveness of the plant oils is due to their repellency and ovipositional detterent effects on stored products and the effeciency of vasambu rhizome powder was due to the presence of active principle, keta osarone which induces premature death of insects.

Résumé :

The IGPC Engineering Department designed basic projects for powder detergent production plant, using technology developed in the IGPC laboratories, in 1998. - 2000. Several projects were completed: technological, machine, electrical, automation. On the basis of these projects, a production plant with a capacity of 25,000 t/y was manufactured, at "Delta In", Zrenjanin, in 2000.This technology was an innovation, because new approach in mixing a powder materials was used, as well as introducing a new type of dryer in detergent production. The product meets all quality demands for detergents with high specific weight (1000 g/l), as well as environmental regulations. The detergent production process is fully automatized, and the product has uniform quality. There is no waste material in detergent zeolite production, because all products with unsatisfactory quality are returned to the process. The production process can be controlled manually, which is necessary during start-up, and repairs.

Résumé :

The study was conducted in the Laboratory of Plant Science and Biotechnology Department, Federal University of Lafia, Nasarawa State to investigate the insecticidal potency of three spices powder namely black pepper (Piper nigrum L.), ginger (Zingiber officinale L.), and true green (Ellectaria cardamom L.), against wheat weevil (Tribolium castaneum) on stored wheat grain. Spices powder was added separately to 20g of wheat grain in plastic containers at four dosages 0.15, 0.27, 0.37, and 0.5% (w/w) while control had no spices powder. Twenty insect pests (Tribolium castaneum) were introduced into each container. Mortality counted in each treatment was recorded after 7, 14, 21, 28 and 35 days. All treatments were replicated three times. Variations were significantly observed in the overall effect of different plant powders on the mortality of weevils extracted from wheat kernel. Weevils treated with Piper nigrum powder exhibited the highest mean mortality (16.37), followed by Ellectaria cardamom (16.05) and lastly Zingiber officinale (13.82). from the result obtained, it is evident that the spice powders possessed insecticidal properties which if fully extracted could be used in post harvest treatment of wheat grain on storage

Résumé :

Specific activities of phenolic compounds produced from the fruiting bodies of the fungi PO and AB (the locally produced strain in Iraq) obtained from the Department of Plant Protection - Department of Organic Agriculture - Baghdad - Iraq were studied. Then, the phenolic compounds were determined after cleaning, drying and grinding the fruiting bodies. The alcoholic extract of the two fungi was prepared by adding 0.2 g of fruiting bodies powder per (1) ml of 98% ethyl alcohol, where the mixture was filtered, concentrated and kept in the refrigerator until use. The aqueous extract was prepared by adding 25 g of fruiting bodies powder per 500 ml of boiled distilled water. Similarly, the mixture was mixed, filtered and stored in the refrigerator until use. The study findings confirmed the existence of significant differences at the probability level (P ˂ 0.05) for the alcoholic and aqueous extracts and for the fungi in the content of phenolic compounds. Conversely, the reducing power was increased by increasing the concentrations prepared for the extracts prepared from the two fungi under study. The free radical scavenging method DPPH was used to estimate the antioxidant activity of alcoholic and aqueous extracts and of the fungi PO and AB. Thus, the results showed the superiority of ethyl acetate extract compared to the other used solvents. Keywords: Edible fungi, phenolic compounds, reducing power, free radical scavenging.

Résumé :

The aim of the study is to determine the possibility of using kelp and black chokeberry powders in bake¬ry product recipes. Objectives: to study the effect of powders on dough quality in various dosages and determine their optimal content; evaluate the quality indicators of finished products. The study was conducted at the Food Technology Department of the Northern Trans-Urals State Agricultural University. The objects of the study were semi-finished wheat bread products with the addition of kelp powder in the amount of 0.5; 1.0; 1.5 and 2 % to the flour weight; semi-finished bakery products with the addition of black chokeberry powder in the amount of 1; 3; 5; 7 % to the flour weight. The addition of kelp powder when kneading the dough increases the water absorption capacity of the dough compared to the control, which has a strengthening effect on the dough structure. The addition of black chokeberry powder to the dough redu¬ces the mass fraction of raw gluten, but also has a strengthening effect. The optimal dosage of kelp powder for adding to the recipe for wheat bread made from premium flour has been established – 2 %, and black chokeberry powder for buns – 3 % of the flour weight. The addition of kelp powder to finished pro¬ducts had the most noticeable effect on the shape and condition of the surface, the size and uniformity of the pore distribution, which can be associated with a greater water absorption capacity of the dough. The addition of black chokeberry powder to the recipe for bakery products had a positive effect on the organoleptic indicators, giving the finished products a pleasant berry taste and aroma. Bakery products were characterized by greater dimensional stability, uniform thin-walled porosity.

Résumé :

Moringa (Moringa oleifera), indigenous to India and Africa, is esteemed for its dual utility as a minor timber source and, more importantly, as a vegetable crop. The leaves of the moringa tree are exceptionally nutrient-dense, containing essential elements such as iron, calcium, proteins, vitamins A, C, and E, dietary fiber, phosphorus, and potassium, all vital for human health. Furthermore, these leaves are rich in antioxidants, including flavonoids and phenolics, which endow them with significant medicinal properties. Despite its sporadic cultivation hindering global availability, the production of moringa leaf powder presents a viable strategy to bolster its international export potential. This study aims to assess the efficacy of various drying techniques in producing moringa leaf powder while preserving its nutritional integrity. Conducted at the Post-Harvest Technology Laboratory within the Department of Horticulture, Rajasthan College of Agriculture, and the Department of Processing and Food Engineering, College of Technology and Agricultural Engineering at Maharana Pratap University of Agriculture and Technology, Udaipur, Rajasthan, India, this research evaluates the nutritional quality of moringa leaf powder produced via different drying methods and from leaves of varying ages. Our findings indicate that the fluidized bed dryer excels in preserving the nutritional quality of the powder compared to tray and heat pump dryers. Additionally, the study concludes that heat pump dryers are unsuitable for producing high-quality moringa leaf powder.

Résumé :

AbstractCemented carbide tools suffer from many issues due to the use of tungsten and cobalt as raw materials. Indeed, those are listed by the European Commission as “critical raw materials” since 2011 and by the US Department of Interior as “critical minerals” in 2018. To remain competitive with the conventional high-speed steels, less performant but cheaper, WC–Co tools can be recycled. In the present paper, a WC–7.5Co powder, recycled by the “Coldstream” process, has been sintered with vacuum sintering. As preliminary experiments have shown that the sinterability of the powder is low, the sintering temperature was set at 1500 °C to achieve full density. In parallel, the influence of ball milling conditions (rotation speed and milling medium) on the reactivity of the recycled powder has been studied in terms of grain size distribution, hardness, and fracture toughness. The optimized milling conditions were found to be 6 h wet milling, leading to a hardness of about 1870 HV30 and a toughness of about 10.5 MPa√m after densification. The recycled powder can thus totally compete with conventional powders, opening avenues for the recycling of cemented carbide tools. Graphical Abstract

Résumé :

The KTH Department of Materials Science and Engineering has lacked powder metallurgy research for many years, and as this field is constantly gaining in importance, such research needs to be reestablished. This requires the department to be able to accurately and efficiently characterize the properties of a powder, such as size distribution and composition, and in the short term, this needs to be done using non-specialized equipment. This project aimed to assess the availability and usefulness of both traditional and novel characterization methods by way of trial characterization experiments as well as a literature review. The experiments resulted in some data about three sample powders, as well as the conclusions that size distribution could be effectively characterized by automatized image analysis, composition could be characterized using Energy Dispersive X-ray Spectroscopy and that sample preparation was key to good results. It was concluded that the department could conceivably evaluate the most important properties, but that sampling and sample preparation routines need to be established to ensure efficient characterization and representative data.
Materialinstitutionen på Kungliga Tekniska högskolan har i många år helt saknat pulvermetallurgiforskning och eftersom detta fält ständigt blir mer relevant behöver denna forskning återetableras. Detta kräver att institutionen med tillräcklig noggrannhet och effektivitet kan bestämma egenskaper hos ett pulver, såsom storleksfördelning och sammansättning, och på kort sikt behöver detta ske med ickespecialiserad utrustning. I detta projekt har tillgänglighet och användbarhet hos både traditionella och innovativa analysmetoder utvärderats med hjälp av experimentell karaktärisering av pulver samt en litteraturstudie. Experimenten gav data om de tre undersökta pulvren och resulterade även i slutsatsen att storleksfördelning kunde bestämmas med automatiserad bildanalys, att samansättning kunde bestämmas med Energi Dispersiv Röntgen Spektroskopi och att provpreparering äravgörande för bra resultat. Av detta följer att institutionen rimligtvis kan bestämma de viktigaste egenskaperna hos ett pulver, men att rutiner för provtagning och provpreparering behöver etableras för att säkerställa effektiv analys och representativ data.

Texte intégral

Résumé :

Le Service des poudres, ancien organisme d'Etat chargé de la production des munitions et explosifs pour les forces armées françaises, est au cœur des changements institutionnels, techniques et conceptuels de l'armement au cours du siècle dernier. Il se modernise en profondeur, depuis la Première Guerre mondiale, afin de répondre aux défis de la guerre moderne. Cette modernisation bouleverse une institution historique qui se tourne peu à peu vers de nouveaux armements, dont le nucléaire militaire.Cette nucléarisation poudrière participe à un repositionnement du Service des poudres au sein des acteurs de l'armement. La recherche de reconnaissance institutionnelle des ingénieurs militaires des poudres favorise leur rapprochement et leur coopération avec le Commissariat à l'énergie atomique dans le cadre du programme de l'arme atomique, à partir des années cinquante.Cette thèse cherche à saisir les transformations produites par cette orientation poudrière vers le nucléaire militaire sur le Service des poudres, ses acteurs et ses sites (les poudreries du Bouchet dans l'Essonne, de Saint-Médard en Gironde, du Ripault en Indre-et-Loire et le fort de Vaujours).L'enjeu de l'autopropulsion (les propergols) oriente également le Service des poudres vers un renouvellement de ses activités pour répondre à une industrie missilière en plein essor. Cette trajectoire rejoint celle de l'armement atomique à travers les missiles nucléaires.Le sujet amène ainsi à comprendre l'évolution d'un système industriel dans un domaine hautement stratégique. Le Service des poudres s'adapte et parvient à une nucléarité poudrière essentielle pour l'armement atomique. Pourtant, il subit la relégation au sein des acteurs de la Défense et finit par disparaître en 1971. Cette thèse éclaire ce paradoxe
The Powder Service, a former state body responsible for the production of munitions and explosives for the French armed forces, is at the heart of the institutional, technical and conceptual changes in armaments over the last century. It modernizes in a professional form, leading to the first of the world war, which responds to the defeats of modern warfare. This upheaval of modernization is a historical institution which is gradually passing through new armies, and not the nuclear army.This nuclearization powder magazine contributes to a repositioning of the Powder Service within the arms industry. The search for institutional recognition of military powder engineers encouraged their rapprochement and cooperation with the Atomic Energy Commission within the framework of the atomic weapons program, starting in the 1950s.This thesis seeks to grasp the transformations produced by this powder orientation towards military nuclear power on the Powder Service, its actors and its sites (the powder mills of Bouchet in Essonne, Saint-Médard in Gironde, Ripault in Indre-et -Loire and the fort of Vaujours).The issue of self-propulsion (propellants) is also directing the Powder Department towards a renewal of its activities to respond to a booming missile industry. This trajectory joins that of atomic weaponry through nuclear missiles.The subject thus leads to understanding the evolution of an industrial system in a highly strategic area. The Powder Department adapts and achieves powder nuclear power essential for atomic armament. However, he suffered relegation within the Defense players and ended up disappearing in 1971. This thesis sheds light on this paradox

Gains, Francesca. « Understanding department : next steps agency relationships ». Thesis, University of Sheffield, 1999. http://etheses.whiterose.ac.uk/6028/.

Texte intégral

Résumé :

This thesis examines the establishment of 'Next Steps' agencies in government and how they were intended to allow the delivery of government goals at arm's length. The research is concerned with how changes in relationships at the heart of Government can be understood. It seeks to address the impact of these changes on the policy process. It does so by examining the nature of the relationship between departments and agencies and asking why some relationships appeared to have worked well and others have not. These questions are not adequately addressed in the existing literature on agencies. The thesis takes a multiple case study approach and draws on the concepts of historical institutionalism, power dependency and policy networks to approach these questions. It is argued that the introduction and development of agencies changed the formal and informal institutional 'rules of the game', affecting the roles actors expected to play and radically altered the distribution of resources in central government. The changed distribution of resources led to the development of new power dependent networks between departments and agencies. Path dependency in the development of the Next Steps concept led to a tension between the idea of agencies operating at 'arm's length' with the continuation of traditional accountability arrangements. The key argument presented is that, where department-agency networks are based on shared values, goals and institutional support, they will be able to manage the tension created by the new institutional arrangements and are able to successfully deliver government goals. In concluding, it is suggested that understanding department-agency relationships as power dependent networks presents three implications. Firstly, for the applicability of this analytical framework to other 'institutional arrangements', secondly for policy making in the core executive and, finally, for insights on normative issues of accountability and autonomy in contemporary governance.

Texte intégral

Résumé :

Aim: This study aims to investigate the factors that affect the practices of effective knowledge sharing in the Middle East region. Method: The research paper is based on a single case study about the internal audit department in a commercial Lebanese bank. Qualitative research methods have been applied which included semi-structured interviews. Results & Conclusion: The research results suggest that organizational, individual and IT are the factors affecting knowledge sharing practices at the bank. However, one of the main issues is related to the national cultural and more specifically to how power distance, individualism, and masculinity are spread throughout the IA department and proving a moderating effect towards organizational, individual and IT factors. This research paper shows that power distance is one of the main contributing factors concerning knowledge sharing. Barriers such as trust, lack of reward system, and centralized organizational structure and lack of information technology infrastructure are regarded as problems in knowledge sharing. However, the empirical results show that the principal issue lies in the power distance. Suggestions for future researches: Suggestions for further researches would be to get the perspectives from an internal audit department at another organization in the Middle East that is following a decentralized organizational structure, having advanced IT infrastructures, along with reward system, in order to compare it with the results given in this study. Furthermore, it would be interesting to make observations at the organization in order to deeply understand how knowledge is being shared at the field. Contribution of the study: This study shows that organizations that are identified with centralized organizational structure, lack of trust, lack of IT support and special rewards system entail different issues with individuals’ knowledge sharing practices. Besides, this research paper provides the organization with insights into what thoughts its employees have when it comes to knowledge sharing. Furthermore, this provides the literature about knowledge sharing in the Middle East with a new model showing the impact of national culture over the factors that affect knowledge sharing practices in the Middle East.

Résumé :

AbstractThe United States remains the world’s preeminent military and technological power. Over the last decade, the United States has increasingly viewed artificial intelligence (AI) proficiency as a vital U.S. interest and mechanism for assuring U.S. military and economic power, recognizing its potential as a force multiplier. As a result, the United States is actively implementing AI across its defense and armed services, with notable applications in Intelligence, Surveillance, and Reconnaissance (ISR), Cyber, Autonomous Systems, Command and Control, Disaster Relief, and Logistics. The United States government is generally well-placed to leverage defense AI and AI-enabled systems. However, various bureaucratic, organizational, and procedural hurdles have slowed down progress on defense AI adoption and technology-based innovation such that the Department of Defense has yet to successfully, on a broad scale, translate commercial AI developments into real military capabilities. The U.S. Department of Defense suffers from a complex acquisition process and a widespread shortfall of data, STEM, and AI talent and training. Organizations working on AI and AI-related technologies and projects are often siloed, separated not only from each other but also from necessary data and other resources, and there exists within the department a culture that favors tried-and-true methods and systems, sometimes trending towards Luddism. In the last few years, however, the Defense Department has made substantial headway on some of these challenges, restructuring its approach to defense AI. However, whether these new AI efforts will be sufficient to allow the U.S. to make up for time lost remains to be seen.

Résumé :

AbstractIn this chapter, our interest lies in analysing the different powers in recruitment and, particularly, how they are manifested in the new tenure track model in technical fields in Finland. Traditionally, recruitment in higher education has mostly relied on the bureaucratic application of processes and on academics, representing professional power, evaluating academic merit. The new university legislation, granting universities more autonomy in recruiting, has allowed the development of increasingly strategic recruitment models. The novel tenure track recruitment criteria exceed traditional notions of individual merits to include assessments of the strategic visions of universities and departments. We see the use of the tenure track model as a shift both in the recruitment for identity building related to the technical university’s strategy and as a shift in using more managerial power in recruitment. We use a case study approach where we look at recruitment in a similar field in two different kinds of universities utilising tenure track, and we examine how bureaucratic, managerial and professional powers are manifested in the processes. The comparisons are used to highlight the powers in the tenure track process in a technical university.

Résumé :

AbstractThis paper focuses on the consumption situation and discounting strategies of members in large department stores. On this basis, reasonable strategies and suggestions for discounting activities in department stores are proposed. It needs to determine the consumption habits of members, customer value, life cycle, discount effect and other information. The mathematical model was established to calculate the activation rate of non-active members in the life cycle of members, that is, the possibility of transforming from inactive members to active members. Based on the actual sales data, the relationship model between the activation rate and shopping mall promotion was determined. Generally speaking, the higher the commodity price is, the higher the profit will be. IA regression model of activation rate and promotion activities is developed. The appraisal index of market promotion activities is established in terms of both discounts and integral. Lasso regression is used for variable screening, and the correlation between activation rate and the above indicators is studied.

Résumé :

Abstract As part of a Department of Energy (DOE) funded program assessing advanced manufacturing techniques for Small Modular Reactor (SMR) applications, the Nuclear Advanced Manufacturing Research Centre (AMRC) and the Electric Power Research Institute (EPRI) have been developing Electron Beam Welding (EBW) parameters and procedures based upon SA508 Grade 3 Class 1 base material. The transition shell, a complex component connecting the lower assembly to the upper assembly is a shell that flares up with varying thicknesses across its section. The component due to its geometry could be built by near net shape powder metallurgy hot isostatic pressing instead of conventional forging techniques. The demonstrator transition shell here is built from several sub-forging as a training exercise. The complex geometry and joint configuration were selected to assess the EBW as a suitable technique. This paper presents results from the steady state welding in the 60-110 mm material thickness range, showing that weld properties meet specification requirements. Weld quality was assured by Time-of-Flight Diffraction (ToFD). The transition shell was completed by welding a flange to the assembly. The presented transition shell assembly represents 6 welded sections all fabricated in below 100 min total welding time.

Texte intégral

Résumé :

Abstract. Hot-isostatic pressing (HIPing) of powders is achieved by placing them inside a canister, which is then evacuated and sealed. Canister filling is a critical step. Consistency in powder packing in the canister and increases in packing density will improve process efficiency and the predictability of HIP canister collapse, leading to less wastage. Understanding the effect of powder morphology, properties and characteristics on the can filling process and subsequent compaction is vital to optimizing canister design and the filling system. Conventionally, this has involved conducting numerous costly and time-consuming trial-and-error experiments. Computational modelling offers an alternative optimization path. Discrete element method (DEM) simulation of a powder filling process has been developed by GRI Inc. and its application to the US Department of Energy’s radioactive Idaho calcine powders has been investigated. A comprehensive analysis of a non-radioactive simulant powder has been conducted. A DEM model was developed with validation of the model using experimental data obtained from the filling system development program.

Résumé :

Abstract Existing state of the art thermal spray processes (HVOF, D-Gun, Plasma Spraying) are limited to powder velocities of about 1 km/sec because they rely on the thermodynamic expansion of gases. A new thermal spray process using electromagnetic forces can accelerate powder particles to a final velocity of up to 2 km/sec. At this velocity powder particles have sufficient kinetic energy to melt their own mass and an equivalent substrate mass on impact. The process is based on railgun technology developed by the Department of Defense. A railgun is filled with argon gas and a high energy electrical pulse, provided by a capacitor bank, drives the gas down the railgun to a final velocity of up to 4 km/sec. This gas passes over a powder cloud and accelerates the powder through drag forces. The electrical and powder discharge frequency can be adjusted so that the deposition rate and thermal input to the substrate can be controlled.

Texte intégral

Résumé :

The Department of Energy handbook for airborne releases from nonreactor nuclear facilities bases its bounding airborne release fraction (ARF) for pressurized powders on tests conducted at Pacific Northwest Laboratory (PNL). An analysis is presented that correlates the ARF from these tests. The amount of powder that becomes airborne is correlated in terms of an adjusted airborne release fraction (AARF) equal to the product of the powder entrainment from the powder bed and the ratio of the total vessel volume to the volume occupied by the powder bed. Powder entrainments and release fractions at low pressures are correlated using a fluidized bed analogy. The analysis shows that the entrainment is enhanced by a sonic shock if the pressure prior to the rupture exceeds approximately 33 psig. A secondary, three-dimensional shock is predicted to occur at an initial pressure of approximately 332 psig. A correlation based on this analysis is used to predict the ARF for ruptures of vessels containing plutonium oxide. It is assumed that the oxide is pressurized by hydrogen that is radiolytically generated from adsorbed moisture.

Résumé :

Abstract This paper describes the diagnostic tools used in the development of a new electromagnetic powder deposition system. The instrumentation, interpretation of data, and subsequent decisions regarding the direction of system development are discussed. Important system parameters, their impact on system performance, and techniques to measure them are presented. The electromagnetic powder deposition system is based on railgun technology developed by the Department of Defense. The system drives an ionized plasma sheet down the length of a railgun, reaching a final plasma velocity of 4 km/sec. The high velocity plasma, in turn, snowplows [1] a shock compressed gas column in front of it. This gas column sweeps through a powder cloud and accelerates it by viscous drag to a final velocity of 2 km/sec. Important system parameters include particle velocity, gas velocity, gas column pressure, and plasma propagation and velocity. Diagnostic tools include pressure transducers, a high speed digital framing camera, fiber optics and magnetic probes.

Résumé :

Abstract Dry powder inhalers (DPIs), used as a means for pulmonary drug delivery, typically contain a combination of active pharmaceutical ingredient (API) and significantly larger carrier particles. The micro-sized drug particles — which have a strong propensity to aggregate and poor aerosolization performance — mixed with significantly large carrier particles that are unable to penetrate the mouth-throat region to deagglomerate and entrain the smaller API particles in the inhaled airflow. The performance of a DPI, therefore, depends on entrainment the carrier-API combination particles and the time and thoroughness of the deagglomeration of the individual API particles from the carrier particles. Since DPI particle transport is significantly affected by particle-particle interactions, very different particles sizes and shapes, various forces including electrostatic and van der Waals forces, they present significant challenges to Computational Fluid Dynamics (CFD) modelers to model regional lung deposition from a DPI. In the current work, we present a novel high fidelity CFD discrete element modeling (CFD-DEM) and sensitivity analysis framework for predicting the transport of DPI carrier and API particles. The work integrates exascale capable CFD-DEM and sensitivity analysis capabilities by leveraging the Department of Energy (DOE) laboratories libraries: Multiphase Flow Interface Flow Exchange (MFiX) for CFD-DEM, and Trilinos for leading-edge portable/scalable linear algebra. We carried out a sensitivity analysis of various formulation properties and their effects on particle size distribution with Dakota, an open source software designed to exploit High-Performance Computing (HPC) capabilities of a massively parallel supercomputer. We developed wrappers to exchange information among these state-of-the-art tools for DPI.

Résumé :

Abstract General Electric (GE) is working with the US Department of Energy (DOE) to develop advanced technology fuel (ATF) for light water reactors (LWR) that will have enhanced tolerance to failure under severe accident conditions. The development of materials for the current fuel is aimed at Generation III LWR but findings may be extended to future Generation IV reactors. One of the concepts pursued by GE is to use iron-chromium-aluminum (FeCrAl) or IronClad for the cladding due to its outstanding resistance to reaction with air and steam at temperatures higher than 1000°C. Ferritic FeCrAl alloys have been used for almost nine decades in the industry, but never in nuclear applications, therefore its fabrication and mechanical aspects for nuclear use needs to be evaluated. Results show that billets of FeCrAl can be produced via traditional melting and using powder metallurgy, and these billets can later be processed to high strength full length cladding tubes having less than half a millimeter wall thickness. The tubes can be joined to the caps via several welding processes.

Résumé :

In a qualitative study of 40 women faculty in sciences, engineering, and medicine (http://sites.nationalacademies.org/SexualHarrassment.htm), respondents at all career levels and fields reported a range of sexual harassment experiences, including gender-based harassment (e.g., gendered insults, lewd comments), unwanted sexual advances, stalking, and sexual assault by a colleague. Sexual harassment experiences often diminished study participants' scientific productivity as energy was diverted into efforts to process emotional responses, manage the perpetrator, report the harassment, or work to prevent recurrences. Many women who experienced sexual harassment adjusted their work habits and withdrew physically or interpersonally from their departments, colleagues, and fields. Study participants who disclosed harassment to a supervisor or department leader often reported that the reactions they received made them feel dismissed and minimized. Sympathetic responses were often met with dismissiveness, minimization, or sympathy, but active or formal support was rarely provided, and women were typically discouraged from pursuing further action. Formal reporting using university procedures was often avoided. University-level reporting sometimes damaged women's relationships with department colleagues. Women who disclosed their experiences often faced long-term, negative impacts on their careers. Study participants identified opportunities to address sexual harassment by (1) harnessing the power of university leaders, department leaders, and peer bystanders to affect the academic climate; (2) instituting stronger and better-enforced institutional policies on sexual harassment with clear and appropriate consequences for perpetrators; and (3) advancing the cross-institutional work of scientific and professional societies to change the culture in their fields.
