Wall-thickness changes predicted in hollow-drawn tubing

Hollow-tube drawing or tube sinking theory is based on the concept of continuous distribution of dislocations. Material composition, parameter influence, and die-angle are determining factors in derivation of the theoretical model

Matching Variables with the Appropriate Statistical Tests in Counseling Research

Quantitative research literacy, including matching variables with the appropriate statistical tests, is a key element in counselor education and preparation. Counselor educators are tasked with teaching quantitative research and statistics, which counselors-in-training tend to find anxiety-producing. Authors aimed to provide a succinct overview of matching variables with appropriate statistical tests and provide strategies counselor educators can use to enhance their pedagogy

Unit Testing of Energy Consumption of Software Libraries

International audienceThe development of energy-efficient software has become a key requirement for a large number of devices, from smartphones to data centers. However, measuring accurately this consumption is a major challenge that state-of-the-art approaches have tried to tackle with a limited success. While monitoring applications' consumption offers a clear insight on where the energy is being spent, it does not help in understanding how the energy is consumed. In this paper, we therefore introduce Jalen Unit, a software framework that infers the energy consumption model of software libraries from execution traces. This model can then be used to diagnose application code for detecting energy bugs, understanding energy distribution, establishing energy profiles and classifications, and comparing software libraries against their energy consumption

A Catalog of Architectural Tactics for Cyber-Foraging

Mobile devices have become for many the preferred way of interacting with the Internet, social media and the enterprise. However, mobile devices still do not have the computing power or battery life that will allow them to perform effectively over long periods of time or for executing applications that require extensive communication or computation, or low latency. Cyber-foraging is a technique enabling mobile devices to extend their computing power and storage by offloading computation or data to more powerful servers located in the cloud or in single-hop proximity. This paper presents a catalog of architectural tactics for cyber-foraging that was derived from the results of a systematic literature review on architectures for cyber-foraging systems. Elements of the architectures identified in the primary studies were codified in the form of Architectural Tactics for Cyber-Foraging. These tactics will help architects extend their design reasoning towards cyber-foraging as a way to support the mobile applications of the present and the future

Assessment of hygienic conditions of ground pepper (Piper nigrum L.) on the market in São Paulo city, by means of two methodologies for detecting the light filth

Pepper should to be collected, processed, and packed under optimum conditions to avoid the presence of foreign matter. The hygienic conditions of ground pepper marketted in São Paulo city were assessed in determining the presence of foreign matter by means of two extraction methodologies. This study was carried out during a six-month time period from May to September 2006. The occurrence of light impurities was determined either by the flotation technique following the methodology recommended by AOAC or by enzyme – linked immunosorbent assay (ELISA). It was observed that 100% of the examined samples contained insect fragments, and many samples were housing more than one type of foreign matter. Twentytwo percent of samples were unqualified for consumption owing to the occurrence of rodent hairs. For the calibration of ELISA test for quantification of insect contamination level in pepper samples, a range of standard-infested samples was prepared in adding 1, 2, 4, 8 and 10 insects in a control sample to estimate the number of insects in the analyzed samples by measuring optical densities (OD) values with a spectrophotometer. Among the 22 samples, 36.4% of samples presented OD values close to that corresponding to the standard infested with eight insects, 40.9% of samples were comparable to OD of the standard infested with four insects, 18.2% comparable to standard with 10 insects, and 4.5% to the standard with two insects. According to the results observed in the present study, the technique described in AOAC official methods manual was found more suitable for detecting not only the insects but also the additional impurities in analyzed samples, while ELISA is specific to detect myosin from the insect muscle, which undergoes serious degradation with time. Keywords: Pepper, ELISA test , Light filth, AOAC official method

Combinations of idelalisib with rituximab and/or bendamustine in patients with recurrent indolent non-Hodgkin lymphoma

Key Points Combining phosphatidylinositol-3-kinase δ inhibition with rituximab, bendamustine, or both is feasible and active in relapsed iNHL. The safety of novel combinations should be proven in phase 3 trials before adoption in clinical practice.</jats:p

Self-recovery from disasters: an interdisciplinary perspective

This working paper presents the findings from a pilot research project that investigated how disaster-affected households in low- and middle-income countries rebuild their homes in situations where little or no support is available from humanitarian agencies. The project was an interdisciplinary collaboration involving social scientists, geoscientists, structural engineers and humanitarian practitioners. The work was broad in scope. It investigated households’ self-recovery trajectories and the wide range of technical, environmental, institutional and socioeconomic factors influencing them over time. It also considered how safer construction practices can be more effectively integrated into humanitarian shelter responses

The influence of the physical environment on self-recovery after disasters in Nepal and the Philippines

Following a disaster, the majority of families rebuild their homes themselves. In this paper, we consider how the physical environment influences such ‘self-recovery’ by investigating disasters in the Philippines (typhoons Haiyan in 2013 and Haima in 2016) and Nepal (the Gorkha earthquake - 2015). Despite the many differences in the disaster contexts, there are some common barriers to self-recovery (and building back better) in a substantially changed and dynamic multi-hazard, post-disaster environment. These are related to changes in water supply (shortage or surplus), impacts of post-disaster geohazard events on infrastructure (particularly affecting transport) and the availability of technical advice. People face a broad spectrum of challenges as they recover and tackling these ‘geo-barriers’ may help to create a more enabling environment for self-recovery. The findings point to what needs to be in place to support self-recovery in dynamic physical environments, including geoscience information and advice, and restoration of infrastructure damaged by natural hazard events. Further research is necessary to understand the issues this raises for the shelter and geoscience communities, particularly around availability of geoscience expertise, capacity and information at a local scale.<br/
