Published: November 2019

AbstractEnvironmental enrichment (EE) has been shown to improve neural function via the regulation of cortical plasticity. Its capacity to induce functional and/or anatomical repair of miswired circuits is unknown. Ten-m3 knock-out (KO) mice exhibit a highly stereotyped and profound miswiring of ipsilateral retinogeniculate axons and associated deficits in binocularly-mediated visual behavior. We determined whether, and when, EE can drive the repair of subcortical wiring deficits by analyzing Ten-m3 KO and wild-type (WT) mice that were enriched for six weeks from adulthood, weaning or birth in comparison to standard-housed (SE) controls. Six weeks of EE initiated from birth, but not later, induced a significant reduction in the area occupied by ipsilateral retinogeniculate terminals in KOs. No EE-induced correction of mistargeted axons was observed at postnatal day (P)7, indicating that this intervention impacts pruning rather than initial targeting of axons. This reduction was most prominent in the ventrolateral region of the dorsal lateral geniculate nucleus (dLGN), suggesting a preferential pruning of the most profoundly mistargeted axons. EE can thus partially repair a specific, subcortical axonal wiring deficit, but only during an early, developmentally-restricted time window.
Shares price in Brazilian agricultural sector

Published: November 2019

The objective of this scientific article is to identify the relevant indicators to explain the shares price, considering the influence of two accounting moments. The Brazilian companies belonging to the food and beverage and paper and pulp sectors that provided information for the 60 quarters within the periods 2001-2007 and 2010-2016 were used. ARIMA or Box-Jenkins models and regression models with the use of dummy variables were applied. The authors express their preference for net profit and earnings per share to make predictions, the inclusion of yield on investment in this study offers a more reliable and comprehensive result because, unlike earnings, it represents the results of management on capital invested. The variables presented can be used to predict the shares price; the investment yield shows relevance over the rest of the variables in only one of the sectors studied. The change of period was found to have a significant impact on these results.RESUMENEl objetivo del artículo de investigación es identificar los indicadores relevantes para explicar el precio de acciones considerando la influencia de dos momentos contable.

Introduction: In recent decades, a significant increase has been observed in the average weight of people due to fast food consumption, which increases the risk of developing diabetes and cardiovascular diseases. Given the importance of this issue, this study was conducted to investigate the predictors of fast food consumption based on the Prototype/Willingness Model among students the School of Public Health in Rafsanjan City.
Methods: In this cross-sectional study, 129 students from Rafsanjan School of Public Health were studied using the census method. The data were collected using a researcher-made questionnaire by self-report. Data analysis was conducted using the SPSS version 20 and statistical tests of correlation and regression analysis.
Results: According to the Prototype/Willingness Model, the mean and standard deviations of the attitude, positive perceptions, tendencies to fast food consumption, intention to not consume fast food, and negative mental norms about fast food consumption were 13.76±3.61, 17± 4.35, 7.4 ±1.58, 6.27± 4.19, and 7± 3.11, respectively. Considering the scores of the Prototype/Willingness Model, the attitude construct had the best score with 68.8% of the total attainable score. Based on the results of the correlations, a significant positive correlation was found between the intention to avoid consuming fast food and negative subjective norms to fast food consumption. Moreover, a significant negative correlation was observed between the constructs of attitude, positive images, and willingness to fast food consumption. Linear regression analysis showed that all constructs of the studied model could predict 0.40% of the variance in the intention to avoid consuming fast food. In this regard, the negative subjective norms to fast food consumption was strongest construct.
Conclusion: Subjective norm is defined as one's important individuals' belief about performing a behavior . Thus, subjective norms changes in the negative direction towards consuming fast foods is effective based on the Prototype/Willingness Model.

Published: November 2019

» Skeletal traction is a fundamental tool for the orthopaedic surgeon caring for patients with traumatic pelvic and lower-extremity injuries.» Immobilization of fractures in the pelvis, acetabulum, and proximal part of the femur can be difficult with traditional splinting techniques. Skeletal traction has proved to be an effective alternative means of immobilization in such cases.» Traction may be utilized for both temporary and definitive treatment of a variety of orthopaedic injuries.» With the appropriate knowledge of regional anatomy, skeletal traction pins can be placed safely and with a low rate of complications.» Several methods for placing skeletal traction have been described, and it is critical for orthopaedic surgeons not only to be proficient in their application but also to understand the appropriate indications for use.
Guest Editorial: From Blockbuster to Blockchain: How to Manage a Not-Quite-Settled Technology Platform

Guest editorial
In this era of Netflix and online media that can be accessed anywhere, it is easy to forget that we used to have to work a little harder to get entertained. In the first few years of the new millennium, a typical home movie experience often began with a trip to the local Blockbuster store. There was a bewildering array of plastic movie cases that you had to pick up and investigate before making your final selection. Upon reaching the cashier, the sales associate would retrieve the appropriate disc for your selected movie and put it in the box before sending you on your way.
What made this ritual all the more challenging, however, was the fact that there was more than one type of disc format during the period 2006–2008. On one side of the store were the movies available for the HD DVD format, a technology platform led by Toshiba; on the other, movies for Sony’s Blu-ray machines. For the most part, the companies that produced movies had pledged allegiance to one of the formats or the other, but not to both of them. Blockbuster customers during this period were consequently faced with a dilemma. Everyone who had witnessed the drawn-out battle between VHS video tapes and Sony’s Betamax in the previous generation of Blockbuster products suspected that some kind of shakeout in the disc industry would probably happen eventually, and no one wanted to be left holding the bag with a disc player and movie collection tethered to the losing side. Thankfully, however, this problem was solved when Toshiba threw in the towel in 2008, leaving Sony’s platform as the undisputed winner in the movie disc technology war.
This episode in the history of the entertainment industry is an important lesson to remember as we think about how to introduce blockchain into the oil and gas industry. Blockchain is essentially “a mathematical structure for storing data in a way that is nearly impossible to fake” (Orcutt, 2018), which makes it a useful way to reliably share all kinds of valuable information (Tapscott and Tapscott, 2016). In the finance sector, blockchain is most famously the technology underlying cryptocurrencies like Bitcoin, but new applications are being discovered all the time—including in the upstream oil and gas industry. Companies in the oil and gas sector have already made inroads into the blockchain domain by using the technology to improve trading (Braga, 2018), guarantee the authenticity of wellbore rock and fluid samples (Whitfield, 2018), and create a shared consensus about the progress of drilling campaigns (Rassenfoss, 2018). In fact, there is so much buzz and energy in the blockchain area these days that several consortia and research initiatives have popped up to figure out new and inventive ways to deliver value with it, including the Enterprise Ethereum Alliance and the Linux Foundation’s Hyperledger project (for both of which Intel was a founding member) or the Oil and Gas Blockchain Consortium.
Questions Over Permeability Prompt Producer-Led Group To Rebuild Key Fracture Diagnostic
Authors: Jacobs Trent 
Published: November 2019

For the past 20 years, the diagnostic fracture injection test (DFIT) has been used across the frontlines of the shale revolution to paint a picture of what cannot be seen. However, that picture has not always been so clear in the eyes of subsurface engineers.
It is not the test has been questioned. It is the way a DFIT is analyzed.
Last year, a joint-industry project supported by six shale producers formed to develop a new methodology that aims to bring fractures into sharper focus—especially when it comes to obtaining accurate permeability estimates from within shale gas formations.
The operators who funded and shared field data for the project were ConocoPhillips, Hess, Shell, Equinor, Range Resources, and Apache. The other key participants included oilfield services firm Keane Group (recently renamed NextTier Oilfield Solutions) and a startup called ResFrac whose software was used to run the study’s models and numerical simulations.
The group’s existence reflects both the rising value of pressure data in unconventional engineering and the struggles industry has in trusting it. The outcome of this yearlong study though hopes to improve upon the latter. The group has offered to the unconventional sector a new template for DFIT analysis, one that represents a distinct alternative to the classical methods used by most practitioners today.
“We have a slightly different conceptual approach, and that impacts a lot of details. So it was necessary to basically start from scratch and make a new procedure,” said Mark McClure, a principal researcher in the industry study and the chief executive of ResFrac.
The new procedure is the centerpiece of two technical papers recently shared at the Unconventional Resources Technology Conference (URTeC) in Denver, and the SPE’s Annual Technology Conference and Exhibition (ATCE) in•Calgary.
Usually performed at the toe-end of a horizontal well, a DFIT involves pumping a small volume of fluid (typically 20•bbl or less) into the formation to induce a small fracture. How that fracture seals back up is then measured over a period that usually spans a 1–3 weeks.
The test is used widely across shale plays to obtain estimates of rock stress, pore pressure, and, perhaps most importantly, permeability. It has become ubiquitous in the shale sector because it is an affordable way to quantify such properties before a pressure pumping crew arrives on a well pad. Additionally, where rock cores are susceptible to stress and permeability changes as they are brought to surface, the DFIT represents an in situ measurement that avoids these issues.
However, the operator-led study asserts that the shale sector has misinterpreted the signals provided by a DFIT. The reason: accepted interpretation methods were largely designed for conventional reservoirs that feature far simpler physics than those that dominate tight-rock formations. The result: a systematic inflation of permeability estimates in gas shales and, to a lesser extent, inaccuracies in permeability estimates of oil shales.

Abstract
Background: The emergence and spread of ST11 carbapenem-resistant, hypervirulent K. pneumonia (ST11-CR-HvKP) in China generated great concern from the public health community. The identification of ST11-CR-HvKP strain is expected to become a serious public health issue in China, considering the carbapenem resistance and virulence had converged in an epidemic clone. However, the underlying mechanism that enables its wide dissemination in China remains unclear.Results: Here, we investigate the prevalence of carbapenemase-producing Enterobacteriaceae (CPE) carriage by inpatients in a teaching hospital over a 1-year period, to identify ST11-CR-HvKP reservoirs, and to understand the transmission of these pathogens across healthcare networks. We identified a high colonization prevalence of CPE (12.4%) among inpatients with diarrhea. Correlations were detected between antibiotic exposure, surgical history, and being CPE positive. A genomic investigation of 65 CRKP isolates indicated a shared bacterial population among various wards. Maximum-likelihood phylogenetic tree demonstrated that these isolates were partitioned into three major clades. An analysis of the wzi locus revealed three different K types (KL105, KL47, and K64) among the ST11 isolates, indicating genetic diversity among these isolates. Our review of the cases showed that these patients had no contact with each other, indicating nosocomial transmission. Genetic and sequence mapping revealed complexity in the existence of virulence plasmids and resistance plasmids in the ST11-CRKP isolates. These data indicate that this process was more complicated than was earlier anticipated, as it may have involved multiple ST11 K. pneumoniae lineages and a variety of virulence plasmids. Conclusions: Collectively, this work represents the first evidence of gut microbiota may act as the source of ST11-CR-HvKP isolate. Active surveillance approaches, particularly in ICUs based on the results of this study, should be implemented to combat the spread of ST11-CR-HvKP and to improve patient outcomes.
