Published: January 2019

Today administrative mechanisms of ecological management are primary in Russia. Their inefficiency is defined by absence of advancing influence and the due control. These mechanisms, as a rule, start to operate when negative influence is already made and harm to the environment is done. The work urgency is caused by the sharpness of the water legislation and regulation problems in Russia, as this sphere is the crossroads of all industrial, agricultural interests and also providing good life conditions for the population. The urgency of ecological-economic modelling is caused by rapid development of ecological management systems in the last years. That is stimulated by the aspiration of market participants to raise management efficiency of the enterprises, to lower power and resources consumption, to raise the quality of goods and services, to create more comfortable working conditions, to provide safety of the personnel and, as a result, to improve the reputation and to raise theircompetitive advantages.
The purpose of the work is to draw up and to deicide a problem of ecological-economic optimization within the limits of linear programming for a “water user – water body” system. Such a linear programming problem is similar to the model of investment projects choice. The problem’s solution is based on searching the best, from the economic point of view, sewage treat system to maintain maximum allowable discharge of substances into the water body.

Significance Statement
The seasonality of influenza activity contributes to seasonal patterns in morbidity and mortality, particularly among vulnerable populations such as patients with ESRD. However, the relationship between seasonal fluctuations of influenza-like illness (ILI), which encompasses a wide range of respiratory infections, and seasonal patterns of mortality in patients with ESRD has not been explicitly examined. Using data from a Centers for Disease Control and Prevention (CDC) ILI surveillance network and the Medicare ESRD database, the authors found that community ILI activity is associated with seasonal variation in mortality among patients with ESRD, and likely contributes to >1000 deaths per year. Greater emphasis on surveillance efforts, such as timely reporting to the CDC of ILI activity within dialysis units, and study of treatment and containment strategies during high-risk periods, may be warranted.

Background
Morbidity and mortality vary seasonally. Timing and severity of influenza seasons contribute to those patterns, especially among vulnerable populations such as patients with ESRD. However, the extent to which influenza-like illness (ILI), a syndrome comprising a range of potentially serious respiratory tract infections, contributes to mortality in patients with ESRD has not been quantified.

Methods
We used data from the Centers for Disease Control and Prevention (CDC) Outpatient Influenza-like Illness Surveillance Network and Centers for Medicare and Medicaid Services ESRD death data from 2000 to 2013. After addressing the increasing trend in deaths due to the growing prevalent ESRD population, we calculated quarterly relative mortality compared with average third-quarter (summer) death counts. We used linear regression models to assess the relationship between ILI data and mortality, separately for quarters 4 and 1 for each influenza season, and model parameter estimates to predict seasonal mortality counts and calculate excess ILI-associated deaths.

Results
An estimated 1% absolute increase in quarterly ILI was associated with a 1.5% increase in relative mortality for quarter 4 and a 2.0% increase for quarter 1. The average number of annual deaths potentially attributable to ILI was substantial, about 1100 deaths per year.

Conclusions
We found an association between community ILI activity and seasonal variation in all-cause mortality in patients with ESRD, with ILI likely contributing to >1000 deaths annually. Surveillance efforts, such as timely reporting to the CDC of ILI activity within dialysis units during influenza season, may help focus attention on high-risk periods for this vulnerable population.
ENTRE DIREITOS, REGALIAS, REGRAS E CASTIGOS: sentidos de justiça nas cadeias do Distrito Federal
Authors: Barreto Lemos Carolina 
Published: January 2019

O objetivo deste trabalho é analisar os sentidos de justiça nas cadeias do Distrito Federal, explorando principalmente sua associação com o acionamento das categorias nativas direitos, regalias, regras e castigos e as articulações entre as práticas locais e a legislação pertinente à execução penal. As reflexões apresentadas fazem parte dos resultados de uma pesquisa etnográfica realizada em cadeias do DF entre 2014 e 2016. A análise revelou que os sentidos locais de justiça constituem uma dimensão central do encarceramento. Elas são recorrentemente articuladas por presos/as como experiências de injustiça, caracterizadoras de formas de desconsideração que negam sua dignidade e identidade. A análise também apontou instâncias de produção e aplicação de normas que traduzem uma concepção de justiça singular, profundamente marcada por um viés autoritário, que caracteriza a cultura punitiva no Brasil.
Criminal Justice Barriers to Treatment of Opioid Use Disorders in the United States: The Need for Public Health Advocacy
Authors: Csete Joanne 
Published: January 2019

Expanding access to treatment of opioid use disorder (OUD) is central to addressing the US overdose mortality crisis. Numerous barriers to OUD treatment are encountered in criminal justice institutions and processes, with which people with OUD are disproportionately involved. OUD treatment access is severely limited in US corrections facilities, with few exceptions. Drug treatment courts, which in principle provide court-supervised treatment as an alternative to prison, have also unduly limited treatment options, particularly medication-assisted treatment. The voice and expertise of health professionals are urgently needed to remove these barriers and ensure that criminally accused persons are systematically linked to the care they need.

Published: January 2019

Objectives. To determine the economic benefit of “modern” nonemergency medical transportation (NEMT) that utilizes digital transportation networks compared with traditional NEMT in the United States. Methods. We used the National Academies’ NEMT cost-effectiveness model to perform a baseline cost savings analysis for provision of NEMT for transportation-disadvantaged Medicaid beneficiaries. On the basis of a review of the literature, commercial information, and structured expert interviews, we performed a sensitivity analysis to determine the incremental economic benefit of using modern NEMT. We estimated confidence intervals (CIs) by using Monte Carlo simulation. Results. Total annual net savings for traditional NEMT in Medicaid was approximately $4 billion. For modern NEMT, estimated savings on ride costs varied from 30% to 70%. In comparison with traditional, modern NEMT was estimated to save $268 per expected user (95% CI = $248, $288 per member per year) and $537 million annually (95% CI = $496 million, $577 million) when scaled nationally. Conclusions. Modern NEMT has the potential to yield greater cost savings than traditional NEMT while also improving patient experience. Public Health Implications: Barriers to NEMT are a health risk affecting high-need, economically disadvantaged patients. Economic arguments supporting modern NEMT are important given decreased support for human services spending.
Technology Focus: Formation Damage (February 2019)
Authors: Fleming Niall 
Published: January 2019

Technology Focus
Formation damage: Do we always need to have a high focus on its prevention, or do occasions exist when it really does not matter? We use significant resources in terms of personnel and testing for the avoidance of formation damage. For new field developments, large studies are undertaken to identify the optimal fluid selection and pumping sequences for producers and injectors. Such studies also ensure compatibility between the fluid candidates and the relevant production/injection intervals and lower completion designs. A similar approach is made when an asset changes fluid vendor.
However, in all this fluid evaluation, do we ever consider the actual significance of formation damage during the well lifetime? Take the example of fluid qualification for a produced-water-reinjection well. We perform corefloods to identify the least-damaging drilling and completions fluids. At the start of injection, we have a well with good injectivity, but, after a few weeks in operation, we notice a sharp decline in volumes being injected. The cause has nothing to do with the drilling and completion fluids but rather the injection of produced water, which, although within specification, contains fines and oil-in-water emulsion that causes formation plugging. This is a common occurrence for many injectors, with fracturing used to increase injectivity. Given that plugging of the injector is expected a short time after the initiation of injection and that fracturing will be used to bypass the damaged zone, is it useful to spend resources on qualifying nondamaging drilling and completion fluids for such wells?
However, many instances occur where inadequate drilling- and completion-fluid evaluation has resulted in significant formation damage with a corresponding negative effect on productivity. Often, finding the specific cause of the lower-than-expected well productivity can prove to be very demanding. Several detrimental factors can act concurrently, or a single cause may be responsible. Typically, these include sandscreen plugging, inadequate cleanup, fluid incompatibility leading to emulsion formation, mud-solids invasion, and excessive fluid losses, among many others. Simulating the downhole operational sequences through coreflood has been used with varying success to identify the cause of the damaging mechanism if it is related to the drilling and completion fluids used.

Effect of Ligand Type Attached to Zirconium-Based Crosslinkers and the Effect of a New Dual Crosslinker on the Properties of Crosslinked Carboxymethylhydroxypropylguar
Authors: Sokhanvarian Khatere , Nasr-El-Din Hisham A. , Harper Thomas L. 
Published: January 2019

Summary
Hydraulic fracturing has become a common practice in the petroleum industry, and several systems have been developed to obtain a suitable crosslinked polymer for the treatment. However, each system has its strengths and weaknesses. This study aims to investigate the effect of three different ligand types attached to zirconium (Zr) on the performance of carboxymethylhydroxypropylguar (CMHPG) crosslinked with Zr-based crosslinkers with the different ligands. The shear recoverability and rapid viscosity buildup at the high pH of Zr-based crosslinkers were overcome by a new aluminum-zirconium (Al-Zr) dual crosslinker in this research.
The polymer used was CMHPG, and the tests were conducted at pH of 3.8 and 10.8. One of the factors that affects the gel performance is the type of ligand attached to the Zr. Because the Zr-based crosslinkers are shear-sensitive, ligands were introduced to delay the crosslinking until the fluid passes the high-shear environments (perforations). Therefore, in this study, lactate, propylene glycol, and triethanolamine (TEA) were studied as ligands attached to the Zr. Two Zr crosslinkers with almost the same concentration of Zr can display different performances if the ligand attached to the Zr is not the same.
The rapid viscosity buildup at high pH had always been a limitation of Zr crosslinkers; however, a new Al-Zr dual crosslinker was introduced in the present study to address this limitation. The Al-Zr crosslinker outperformed all the other crosslinkers examined in the present study. Immediate viscosity buildup at a high pH and a lack of shear recoverability of Zr-based crosslinkers was addressed through the Al-Zr crosslinker. The Al-Zr crosslinker introduced in this study is one compound that is easy to use in the field. The Al-Zr crosslinker performance was compared with the boron-zirconium (B-Zr) crosslinker: Both had lactate as a ligand attached to them. Among all the Zr-based crosslinkers in this study, the Zr crosslinker with lactate and propylene glycol as a ligand performed the best. The CMHPG crosslinked with each of the crosslinkers was tested for proppant-carrying purposes along with static leakoff rates. The results revealed gel-proppant-suspending capabilities and acceptable leakoff rates.
Extensive laboratory research is a key to a successful field treatment. These results indicate that fracturing fluids are complex, and the ligand type is one of the important factors in determining the final properties of fracturing fluids. Therefore, the results of this study will assist in developing Zr-based crosslinkers that address their current shortcomings.
