Published: October 2018

Objective: To develop and validate an educational manual on the prevention and treatment of trench foot for military personnel. Method: This is a prospective, descriptive, observational study. A manual was developed based on a literature review of books, theses and articles published in the last 10 years. The manual was evaluated by an expert committee of the Brazilian Army, and tested and validated by military students from an Army Sargent School in Brazil. Students evaluated the following parameters: definition of trench foot, risk of trench foot development among the military, risk factors, identification of trench foot, preventive measures, treatment of trench foot, and final considerations. Results: A total of 99 military students participated in the testing. Some parameters were exclusively evaluated by the experts, 12 physicians and 11 nurses, and rated as ‘good or very good’ as follows: thematic content (100%), graphic display (100%), topic sequence (100%), clarity of language and comprehension of information (91.3%) and illustrations (95.6%). Other parameters were rated as ‘good or very good’ by both the experts and military students, as follows: definition of trench foot (100% and 85.8%), risk of trench foot among the military (95.6% and 86.8%), risk factors (100% and 82.8%), identification of trench foot (100% and 86.8%), preventive measures (100% and 81.8%), treatment (95.6% and 84.8%) and final considerations (95.6% and 81.82 %), respectively. Cronbach's alpha was 0.891 for consistency and 0.854 for reliability. Conclusion: The educational manual was validated by health professionals, tested by military students, and showed to be a consistent, reliable and valid educational instrument for the prevention and treatment of trench foot.
Development of a multivariate model to predict significant coronary artery disease in Thai patients with left ventricular systolic dysfunction and determine the applicability of coronary angiography: a single-center, retrospective, case–control study
Authors: Methavigul Ratikorn , Methavigul Komsing 
Published: October 2018

Abstract

Background
Coronary angiography (CAG) or stress imaging has been performed in almost all Thai patients with left ventricular (LV) systolic dysfunction. If CAG results reveal insignificant coronary stenosis, such patients are diagnosed with nonischemic cardiomyopathy (NICM); however, CAG is considered to provide no benefit and may even harm these patients because it is invasive.

Objectives
To identify predictors associated with significant coronary artery disease (CAD) (stenosis) in Thai patients with LV systolic dysfunction without angina and without LV regional wall motion abnormality and create a prediction score.

Method
Retrospective data from patients at a single tertiary-care center with LV systolic dysfunction (LV ejection fraction <50%) diagnosed between August 2000 and October 2014 were separated into a group with ischemic cardiomyopathy (ICM) and a group with NICM according to CAG. Predictors associated with CAD found in normal populations were determined. Multivariate analysis was used to identify predictors associated with significant coronary stenosis in patients with LV systolic dysfunction to develop a model to create a prediction score.

Results
We included data registered from 240 Thai patients with LV systolic dysfunction. Predictors associated with ICM were age (>60 years), sex (male), and a history of diabetes mellitus (DM). Predictors associated with NICM were body mass index (BMI) >25 kg/m2 and the presence of left bundle branch block (LBBB) on electrocardiography. A simplified equation to predict significant CAD in patients with LV systolic dysfunction is: 3(male sex) + 3(age >60 y) – 5(BMI >25 kg/m2) - 5(LBBB) + 5(DM) - 5. The sensitivity and specificity of this score are 60.5% and 85.1%, respectively.

Conclusion
Our prediction score has modest sensitivity, but high specificity for predicting significant CAD and can be used to determine who should not undergo CAG.

What is happening to laboratory medicine in Denmark?
Authors: Jørgensen Per E. 
Published: October 2018

Abstract
A number of current trends will affect and probably change laboratory medicine, as we know it. Scientific and technological developments, digital health with big data and artificial intelligence, and centralization will change the interfaces among the specialties of laboratory medicine. They might even challenge the identity of some specialties. Other trends such as demographic changes, increased complexity of health care, digital health with electronic health records, and more demanding and well-informed patients will change the way laboratory medicine specialties deliver their services. This paper discusses the possible changes of laboratory medicine in Denmark – a Scandinavian country where almost all hospitals are public. If Danish laboratories grasp the new possibilities instead of trying to avoid them, laboratory medicine is likely to prosper. Such a positive development will call upon good leadership and a genuine willingness among laboratory specialist to adapt to a future where their own specialty might be very different from today.
Household Disaster Preparedness in New York City before Superstorm Sandy: Findings and Recommendations

Published: October 2018

AbstractThis study focuses on household disaster preparedness in New York City (NYC) prior to Superstorm Sandy occurrence on October 25, 2012. The purpose of our analysis is to explain the level and patterns of disaster preparedness before a relatively rare natural disaster event occurred and to investigate the factors that influenced the capacity of NYC households to prepare for emergencies and disasters. A random telephone (RDD) survey comprised of 2001 NYC residents across all five boroughs was conducted by the NYC Department of Health and Mental Hygiene and completed before Sandy struck the City. These data were explored using frequencies, cross-tabs, and factor analysis to build a path model of household disaster preparedness. Findings indicate that household disaster preparedness levels in NYC are high, especially regarding the acquisition of emergency supplies and communication resources. A trust in local government and assistance from one’s social network are the strongest predictors of general household preparedness. Exogenous variables in our model – low income households and those with functional and access needs residents – will be more vulnerable during an actual disaster since they are less able to access communication technologies to search for self-protective disaster information and to communicate their needs during an emergency.
A finite difference method for the very weak solution to a Cauchy problem for an elliptic equation
Authors: Hào Dinh Nho , Thu Giang Le Thi , Kabanikhin Sergey , Shishlenin Maxim 
Published: October 2018

Abstract
We introduce the concept of very weak solution to a Cauchy problem for elliptic equations. The Cauchy problem is regularized by a well-posed non-local boundary value problem whose solution is also understood in a very weak sense.
A stable finite difference scheme is suggested for solving the non-local boundary value problem and then applied to stabilizing the Cauchy problem. Some numerical examples are presented for showing the efficiency of the method.

Authors: Yambulatov A. M. 
Published: October 2018

Aim. To study the peculiar features of hemogram indices and biochemical indices of blood in children with different vitamin provision.
Materials and methods. Vitamin A, C, D, E, B6 and B12 content in blood was determined in 188 children (aged 5–6 years) of pre-school educational institutions (PEI), who attended PEI for not less than 3 years and had a standard C-vitaminised diet.
Results. The study of a season provision with vitamins A, C, D, E, B6 and B12 showed that 75–85 % of children have a whole-year deficit of vitamins, characterized as polyhypovitaminosis in 40 %. Comparative analysis of blood hematological and biochemical indices in children with different vitamin provision was carried out.
Conclusions. Among children with insufficient vitamin provision there was noted more stressed state of hemopoietic erythrocytic blast and decreased proliferative activity of lymphomonocytic blast against the background of higher activity of allergic-type cell responses; lower level of protein, carbohydrate, mineral and energetic metabolism is observed in children with insufficient vitamin provision.

Rotunda de Ribeirão Vermelho: exemplo emblemático do patrimônio ferroviário brasileiro
Authors: Silva Ronaldo André Rodrigues da 
Published: October 2018

A importância dos complexos ferroviários para a história brasileira compõe-se a partir do desenvolvimento econômico-industrial de meados do século XIX. Constitui-se também uma relação entre a realidade histórico-social das cidades brasileiras e os complexos ferroviários por meio do desenvolvimento de sistemas sociais ou de infraestrutura de cidades e regiões. Dentre as estruturas ferroviárias, destacam-se as rotundas ferroviárias, não somente por sua importância para os complexos ferroviários e manutenção das máquinas, mas pela grandiosidade e identidade arquitetônica. Elas, comumente, constituíram-se como um dos principais edifícios e sempre despertaram interesse, desde sua centralidade nas oficinas à admiração das pessoas por seu tamanho, estrutura e complexidade o que as caracterizaria como elementos emblemáticos. A partir dessas ideias, o trabalho busca apresentar a realidade de um desses exemplares, a rotunda ferroviária de Ribeirão Vermelho, localizada na cidade homônima em Minas Gerais (Brasil). Propõe-se uma reflexão a partir do exemplo e da realidade dessa estrutura ferroviária que reflete, em grande parte, o complexo conjunto de elementos ferroviários no Brasil. Há aquelas que mantêm as suas funções, foram restauradas ou reutilizadas, mas também outras que foram transformadas em equipamentos sociais, e, negativamente, as abandonadas. Ao final, avaliam-se os diversos exemplos de rotundas ferroviárias, desde a reutilização e reconversão ao abandono e arruinamento. Por fim, a reflexão sobre a arquitetura ferroviária, seu aspecto singular e emblemático e sua importância para a memória e a história devem ser entendidos de acordo com as múltiplas e interdisciplinares interpretações acerca do patrimônio cultural e industrial e da memória histórica e social.

Published: October 2018

Abstract
Field "A" produces from a mixed-wet formation comprising of fine grained silicilite. The field is a sour light tight oil reservoir with permeability range from 0.001 – 0.1 mD, the only way to flow the existing vertical wells is through hydraulic fracs. Historically the wells have been fracced using water based frac fluids, which have caused severe negative consequences related to well integrity and reduced productivity. With a recovery factor of &lt;1% after 15 years of production, the main challenge and objective lies in enhancing productivity and unlocking the huge volumes of this reservoir through optimizing the field development concept, completion, frac design and execution.
A study was conducted with a recommendation to develop the field by drilling slanted wells with ~10 - 15 frac stages. The frac design in itself is unconventional or hybrid where the targeted frac half length is 5x more than the existing conventional ones. The use of oil based frac fluid instead of water is an opportunity actively pursued to enhance productivity and eliminate issues related to scale and corrosion that in the past have resulted in a loss of production.
Findings of the study have clearly indicated that developing the field with several slanted multi frac wells is economically attractive; with an increase in Net Present Value (NPV) by ~60% and decrease in Unit Technical Cost(UTC) by ~30% compared to developing the field conventionally with vertical wells.
Use of Rate Transient Analysis to Evaluate Hydraulically Fractured Well Performance in A Mature Gas Field
Authors: Al-Lawati Basayir , Blasingame Thomas 
Published: October 2018

Abstract
In this work, we assess the historical well performance for a mature gas condensate field in Oman (the field name is designated as "BHA," where "BHA" is a pseudonym). The reservoirs of the BHA field are complex and have low permeabilities which results in substantial uncertainty in reserves estimation, which in turn has resulted in regular modifications of the booked volumes. To confine these booked volumes, we employed two techniques: "time-rate" analysis (or Decline Curve Analysis (DCA)) and "time-rate-pressure" analysis (or Rate Transient Analysis (RTA)).
To perform the decline curve analysis work we used Microsoft Excel to match data using both the Modified Hyperbolic (MH) and Power-Law Exponential (PLE) DCA relations. We also used the Kappa Engineering product "Topaze" to conduct the Rate Transient Analysis (or RTA) by first estimating reservoir parameters and then performing a simulation history match of both the rate and pressure data. The DCA and RTA models were both used to construct a 30-year forecast and 30-year EUR values were obtained using these forecasts. Finally, we created parametric correlations using estimated reservoir properties from RTA and the matched parameters obtained using the MH and PLE relations for DCA.
The core purpose of this work was to provide assurance in the booked reserves volumes for these low permeability reservoirs and to obtain correlations of reserves and reservoir property estimates for fields like the BHA field.
The Environmental Impact of Cattle Access to Watercourses: A Review
Authors: O'Callaghan Paul , Kelly‐Quinn Mary , Jennings Eleanor , Antunes Patricia , O'Sullivan Matthew , Fenton Owen , hUallacháin Daire Ó. 
Published: October 2018

The degradation of freshwater resources and loss of freshwater biodiversity by anthropogenic activities, including agriculture, are of major global concern. Together with diffuse pollutants, point sources, such as where cattle have direct access to riparian margins and watercourses, can potentially present significant environmental challenges. These can include impacts on stream morphology, increased sedimentation, nutrient additions, microbial contamination, and impacts on aquatic biota. Mitigation measures aimed at reducing these frequently include reducing the amount of time cattle spend in riparian margins and watercourses. This is often accomplished through the provision of an alternative water supply and grazing management, or even cattle exclusion measures. Although a number of studies refer to potential negative impacts, there has been little attempt to review previous research on this topic. The key aim of this paper is to collate and review these disparate studies, as well as those relating to the effectiveness of mitigation measures. Although it is difficult to draw generalizations from studies due to the inherent variability between and within catchments, evidence pertaining to impacts in relation to sedimentation, pathogens, and riparian margin vegetation were strong. Conclusions in relation to impacts on stream morphology and nutrient parameters were less clear, whereas studies on responses of macroinvertebrate communities were particularly variable, with differences due to cattle access difficult to separate from catchment scale effects. A greater understanding of the impact of cattle access on watercourses under varying conditions will help inform policymakers on the cost effectiveness of existing management criteria and will help in revising existing measures.Core Ideas
It has been hypothesized that direct cattle access to waterways can result in impacts to streams.
Little effort has been made to collate information on the efficacy of mitigation measures.
Divergent results on the effect of cattle access on various parameters highlight the need for further research.
