AbstractCollagen alpha-1(V) chain, encoded by the COL5A1 gene, plays a crucial role in abundant fibrillar collagens supporting many tissues in the body containing type I collagen and appears to regulate the association between heterotypic fibers composed of both type I and type V collagen occurring among others in muscles, tendons and ligaments. Taking this fact into consideration we decided to examine the association between COL5A1 rs12722 and rs13946 polymorphisms, individually and as inferred haplotypes, with anterior cruciate ligament rupture risk (ACLR) in professional soccer players. A total of 134 male professional soccer players with surgically diagnosed primary anterior cruciate ligament ruptures and 211 apparently healthy male professional soccer players, who were without any self-reported history of ligament or tendon injury, were included in the study. Both the cases and the healthy controls were recruited from the same soccer teams, of a similar age category, and had a comparable level of exposure to anterior cruciate ligament injury. Genomic DNA was extracted from oral epithelial cells using GenElute Mammalian Genomic DNA MiniprepKit. All samples were genotyped for the rs12722 and rs13946 polymorphisms using a Rotor-Gene realtime polymerase chain reaction. Statistically significant differences in the genotype frequencies for the COL5A1 rs13946 polymorphisms in dominant modes of inheritance occurred (p = 0.039). Statistically significant differences were documented only in the dominant model under the representation tendency of the C-C haplotype in the ACLR group compared to controls (p = 0.038). Our results suggest that variation in the COL5A1 gene may be one of the non-modifiable factors associated with the ACL injury in professional soccer players. The C-C rs12722-rs13946 haplotype provides a protective effect against the ACL tear.

Published: June 2018

AbstractInformation on how wildlife is affected by pine plantation clearcutting is relevant for designing management strategies to promote biodiversity conservation in productive systems. By comparing the number of records of carnivores in a mosaic of pine plantations and native forest remnants before and after pine harvesting, we assessed the effect of plantation clearcutting on carnivore presence in ten sampling areas in Central Chile. We also included a number of covariates to account for their potential confounding effects, for example, the distance between each site and the nearesting human settlement and vegetation cover. A total of 10 species were observed, but no negative effect of clearcutting on carnivore presence was detected. Only the culpeo fox (Lycalopex culpaeus) responded positively to the harvesting of pine plantations. The threatened kodkod (Leopardus guigna) was absent in clearcut areas and the number of records increased in forests or plantations with a dense understorey. The domestic dog (Canis lupus familiaris) responded positively to human settlements and seems to prefer more open areas. The number of records for the Puma (Puma concolor) and the domestic cat (Felis silvestris catus) was too few, and hence, we could not make any inference regarding these two species. The other species recorded showed different responses to one or more of the included covariates. Although our results showed that the recording of some species could change in the short term after pine harvesting, future studies should assess the impact of clearcutting at a much higher scale, both in terms of space and time.
A Simple Method to Estimate Numerically the Residual Stresses in Bodies Subjected to Cyclic Loads
Authors: Pazdanowski Michał 
Published: June 2018

Abstract
Residual stresses in metallic materials may arise during the manufacturing process as a byproduct of the process itself, or they may be introduced on purpose to enhance the behavior of the product in service (for instance the compressive hoop stress in railroad vehicle wheels). Depending on the service regimen, the residual stresses in a body subjected to cyclic loads may either attain the stable (time-independent) state, thus leading to elasto-plastic shakedown of the body to the given loading program, or may not stabilize, resulting in the destruction of the body because of the ratcheting (alternating plasticity). The residual stresses in a considered body may be calculated using the standard incremental approach, where the final state is found through following step by step the actual loading program, or they may be estimated by the application of plastic shakedown theorems. The first approach, although yielding precise information on body behavior, may be extremely time consuming in the case of cyclic loads. The second approach, although yielding only an estimate of the final residual stress distributions, is much more time efficient. The numerical approach discussed in this article is based on Melan’s theorem and allows for a reasonably accurate estimate of residual stresses induced in an elastic plastic body made of strain hardening material as long as an upper bound of the loading program is known. The tests performed on an autofrettage problem exhibit excellent agreement with an exact analytical solution. The results for the calculations of the residual stresses in railroad rails subjected to simulated service loads are provided.
Residual Stress in Self-Piercing Riveting (SPR) Joints—A Review
Authors: Haque Rezwanul 
Published: June 2018

Abstract
Self-piercing riveting (SPR) is a high-speed method of joining sheet materials by creating a mechanical interlock between the sheets. Unlike conventional riveting, SPR does not require predrilling. Automobile industries adopted this joining technique because of its suitability in joining dissimilar materials and doing so at high-volume production. However, in SPR, the rivet plastically deforms and residual stress develops in the joint. The deformation behavior of the rivet and the residual stress distribution in SPR joints are poorly understood. This leads to difficulties in developing new product and optimizing the process. Development of new rivet and die geometries are also limited since the residual stress state in SPR joints are not fully described. Several key issues in modeling and measuring residual stress in SPR joints are discussed. How the plastically induced residual stress can be linked to the different phases of the riveting process is also described. This is an area of SPR with numerous prospects for research. It is expected that advancement will be achieved by a combination of techniques, including laboratory recreation, finite element modeling and manufacturing trials.
In Situ Investigations of Elastic Strain State in Deep Rolled 4140H Steel by Neutron Diffraction Method
Authors: Meyer Heiner , Epp Jérémy , Pirling Thilo , Zoch Hans-Werner 
Published: June 2018

Abstract
A deep rolling process was applied on 4140H steel specimens with a self-built loading frame and investigated in situ with neutron radiation using the SALSA instrument at the Institut Laue-Langevin (ILL). A neutron diffraction stress imaging approach was developed and used to determine material changes from the surface up to several millimeters inside the material by single expositions. The strains could be evaluated as deviations of the diffraction signal along the height of an area detector, and the theoretical maximum depth resolution was given by geometrical magnification together with the detector pixel size. The results of these experiments together with complementary post-process investigations could be used to link the internal load during the process with resulting material modifications such as the generated residual strains.

Abstract
Expanded austenite is a supersaturated solid solution of nitrogen/carbon in austenite that forms as a case by the diffusion of nitrogen/carbon into austenitic stainless steel. Expanded austenite has a high level of hardness that provides resistance against galling and wear, superior resistance against localized corrosion, and contributes to improvement of the fatigue performance. This latter characteristic is a consequence of the huge compressive residual stresses in the expanded austenite case. Such stresses are induced by the high interstitial content in the austenite lattice and are accommodated elasto-plastically. The experimental assessment of the elastic lattice strains is complicated by the presence of steep composition-depth and stress-depth profiles, which necessitate special measurement or correction procedures to unravel the influence of composition and stress on the lattice spacing and avoid artifacts arising from (steep) lattice-spacing gradients. In the present work the sin2ψ method was combined with grazing incidence X-ray diffraction to keep the information depth during measurement shallow, independent of the (effective) tilt angle ψ. The plastic strains in the expanded austenite 27 zone were estimated from the lattice rotations, as determined with electron backscatter diffraction. It is demonstrated that the level of elastic lattice strains in expanded austenite can be adjusted by retracting part of the dissolved nitrogen. The experimental results for elastic and plastic strains are compared to those predicted by a comprehensive numerical model that simulates the time-dependent development of composition-depth and stress-depth profiles in expanded austenite. The work described in this manuscript is a combination of a review of previously achieved and published results as well as the newest results of ongoing research activities.

Sharing Success: A Review of Strategic Planning, Annual Reports, and Publicly Available Information from Academic Libraries
Authors: Springmier Kaitlin , Edwards Elizabeth , Bass Michelle B 
Published: June 2018

Objective – This paper reports on a study which explored web-based information sharing practices in North American academic libraries. This study specifically focused on how selected academic libraries use data, reports, and other strategic planning documents to communicate success and demonstrate impact to stakeholders, administrators, and peers.

Methods – An environmental scan was conducted to explore the assessment programs and communication practices of 97 North American academic libraries. The population for this study was identified on the basis of several metrics: consortial membership, Association of Research Libraries (ARL) ranking on various criteria, and institutional attendance at the 2014 and 2016 Library Assessment Conferences (LAC). Researchers conducted content analyses on the websites of the 97 libraries to identify measures of institutional support for assessment and to explore the range, depth, and quality of data made available. These iterative analyses were supported by the use of a rubric developed based on emergent criteria observed during multiple phases of review.

Results – Of the libraries reviewed, 57% made some form of data available to the public. The most robust and effective use of data observed in this study involved the use of data to tell stories about the library and its impact. While this study found a positive correlation between libraries with clear investments in assessment and their use of data in public documents, it found that other factors such as an institution’s consortial memberships or funding model may more strongly influence a library’s decision to make data available.

Conclusions – While observations gleaned from this study may serve as a benchmark for evaluating communication practices in academic libraries, further research is necessary to understand how factors within an academic library, its parent institution, or the profession at large may contribute to this decision making process.

Abstract
This paper mainly focuses on the concentration calculation of SO2 in flue gas. There are many methods for smoke detection. First of all, this paper mainly introduces the basic Differential Optical Absorption Spectroscopy technology. Then, in order to solve the problem of overlapping absorption between different gases in the flue gas, this paper use cyclic iteration algorithm to measure the concentration of SO2. It is concluded that the basic DOAS algorithm has a large error for the concentration measurement of mixed gas with overlapping absorption, the he error is above 25%. However, the cyclic iterative algorithm has a good effect on processing with it which can get a more stable result after three iterations, and the measurement error can be controlled finally within 2%.

Distance learning requires improvement of interactivity and initiative to achieve their aptitude. Using a variety of formats data, learners master the initiative in the learning process, it is not easy to lead to deviation from the learning goals phenomenon. To this end, in order to solve this problem, we use the basis of ILTMK theory and distributed interactive technology to introduce the active learning factors and propose a dynamic autonomous knowledge learning model and build its model’s simulation running environment and related mechanism.
