Authors: Анисимов  , Anisimov Maksim
Published: July 2017

Currently, the use of wood plate materials (WPM) in various industries is steadily increasing due to a number of technological and economic advantages. Along with this, there is the improvement of methods of manufacturing and materials used for this purpose. One of the most commonly types of glue used for production of plywood as one of the types of WPM are urea-formaldehyde resins. In the manufacture of adhesive compositions based on them possible to use a wide range of sorbents that provide a variety of improved technological properties, such as adhesive, and the finished plywood. One of these properties is the level of free formaldehyde emissions from finished plywood, which directly affects to the possibility of its using in different rooms and characterizes the level of consumer risks in its operation. Scientifically it proved possible to reduce the level of emission of free formaldehyde from finished plywood with using of natural zeolite clinoptilolite treated in weak pulsed magnetic fields (SIMP) and ultra-high frequency electromagnetic fields (EMF microwave), as a sorbent of urea-formaldehyde resin filler in the manufacture of plywood for general using. This study evaluated the level of consumer risks in the operation of plywood manufactured with sorbent activated in SIMP and microwave EMF. In this paper describes the main influencing factors as well as the possibility of reducing calculation errors in consumer risk shows the feasibility of using a simplified calculation of constant values while respecting the basic influencing factors. Calculations of changes in con-sumer risk for saples of plywood manufactured with using sorbents, activated in SIMP and EMF microwave were made, established decrease by 25 and 33 % respectively.

Published: July 2017

The best method of hardening of low-value wood is pressing her to the extent of 40-50 %. About 2 times its volume decreases and, respectively, but the output of the modified wood. As hardener can be used on-nofibrillyarnuyu cellulose (NFP) in the form of a 2 % hydrogel magnetically activated. Completely replace the pressing NFP is impossible, since hydrogel has a very small concentration of NFP and receive content over 1 % in relation to dry wood impossible. Technology for producing modified wood involves activation of a 2 % hydrogel magnetization in STEL-49 to obtain the analyte with a potential of 600-800 mV and the pH = 2.5. In a 30 % aqueous urea solution was added 20 % activated hydrogel NFP stabilizer and 15 % the size of the particle board - UREAFORMALDEHYDE oligomer aqueous solution (UFC). The resulting mixture is impregnated with crude wood aspen or birch end under pressure to ensure through impregnation. The content of the mixture in the impregnated wood of 40-60 % by weight of the wood. The impregnated wood is dried with simultaneous compression to the extent of 20-25 %. The resulting wood has a moisture content 6-8 %, the density of 800-900 kg / m3, compressive strength parallel to the grain of 100-150 MPa. Due to the presence of urea loss on fire test is reduced 5 times. Biostability modified wood increases from baseline in 2-3 raza.Posle processing wood according to the procedure described obtained modified wood having a degree of compaction of 15 % birch and 25 % aspen, i.e. Use of the method reduces the degree of compaction is twice as compared with the known method, thus also increasing the yield of the resulting material. Reducing pressing for birch from 30 to 15 % increases the yield of modified wood by 15 %, ie 1 m3 with savings of 0.15 m3, with 1000 m3 -150 m3, When the selling price of the modified birch 30 thousand rubles. 1 m3 for savings of 150x30 = 4500 rubles. Reducing the degree of compaction of the aspen from 50 to 25 % increases the yield of modified wood by 25 %, i.e. 1 m3 with savings of 0.25 m3, with 1000 m3 -250 m3. When the selling price of the modified aspen wood 25 thousand rubles. 1 m3 for savings of 250x25 = 6250 rubles.

At present JSC «Russian Railways» forms a coherent policy on safety and reliability of the transportation process, with one of the most urgent is the problem of removing unwanted trees and shrubs in the right of way of railways. In accordance with the applicable instructions in the right of way is not allowed of weeds overgrowth of trees and shrubs. Removal of unwanted trees and shrubs in the right of way mechanical method can be carried out a working body (the cutting head), controlled by manipulator. The article examines the dynamic interaction between the rotor of the working body of unwanted trees and shrubs. On the basis of the actual conditions of the scheme developed by cutting shoots in which the axis of rotation of the rotor axis and are crossed overgrown, is at a distance, is given a number of dependencies. The resultant cutting force is determined taking into account the angle of the cutting speed and the angle of supply and axis deviation shoots under the influence of the tool in the direction of rotor rotation. It is shown that the height of the cut shoots continuously decreases to a certain minimum value determined in accordance with the technological map, and the value can be negative in the case of the interaction of the rotor with the soil. To ensure the effective cutting shoots without a break (to simultaneously transform it into chips the corresponding working body) is given a number of these conditions, the implementation of which depends on the physical and mechanical characteristics of the vegetation removed. Considered a dynamic interaction model rotary working member with trees and shrubs allows you to get a number of important practical recommendations for the whole system of machines having certain common properties.

Authors: Moruzzi Megan , McLeod Anne
Published: July 2017

Hypovolaemia leads to a number of physiological responses that require systematic assessment and interpretation. This article focuses on a case study of a patient with Parkinson's disease who became hypovolaemic after a fall at home, to illustrate the impact of hypovolaemia and current recommendations regarding fluid resuscitation. ABCDE (airway, breathing, circulation, disability, exposure) assessment and arterial blood gas analysis are considered, and interpretation is explained in light of the patient scenario.
Live tweeting by ambulance services: a growing concern
Authors: Baron Aidan , Townsend Ruth
Published: July 2017

Despite advances in technology being a driver of paramedic professional development, particularly over the past decade, the introduction of new forms of technology appears to have presented paramedics with some professional challenges. Paramedics, pre-hospital clinicians, and ambulance service providers in both the United Kingdom and Australia, have begun using social media technology to communicate what they do to the general public. Unfortunately some of the material that has been communicated appears to breach professional standards of practice, and therefore has the potential to cause harm to the patient, the individual paramedic, and the paramedic profession more broadly. This article will present the rationale behind why this behaviour is unprofessional, ethically and legally unsound, and why it must cease. We offer a tool that will assist paramedics, and other healthcare professionals, to practise safe and professional social media use in their workplace.

Reference values of fecal calgranulin C (S100A12) in school aged children and adolescents
Authors: Heida Anke , Kobold Anneke C. Muller , Wagenmakers Lucie , van de Belt Koos , van Rheenen Patrick F.
Published: July 2017

Background:

Calgranulin C (S100A12) is an emerging marker of inflammation. It is exclusively released by activated neutrophils which makes this marker potentially more specific for inflammatory bowel disease (IBD) compared to established stool markers including calprotectin and lactoferrin. We aimed to establish a reference value for S100A12 in healthy children and investigated whether S100A12 levels can discriminate children with IBD from healthy controls.

Methods:

In a prospective community-based reference interval study we collected 122 stool samples from healthy children aged 5–19 years. Additionally, feces samples of 41 children with suspected IBD (who were later confirmed by endoscopy to have IBD) were collected. Levels of S100A12 were measured with a sandwich enzyme-linked immunosorbent assay (ELISA) (Inflamark®). The limit of detection was 0.22 μg/g.

Results:

The upper reference limit in healthy children was 0.75 μg/g (90% confidence interval: 0.30–1.40). Median S100A12 levels were significantly higher in patients with IBD (8.00 μg/g [interquartile range (IQR) 2.5–11.6] compared to healthy controls [0.22 μg/g (IQR<0.22); p<0.001]). The best cutoff point based on receiver operating characteristic curve was 0.33 μg/g (sensitivity 93%; specificity 97%).

Conclusions:

Children and teenagers with newly diagnosed IBD have significantly higher S100A12 results compared to healthy individuals. We demonstrate that fecal S100A12 shows diagnostic promise under ideal testing conditions. Future studies need to address whether S100A12 can discriminate children with IBD from non-organic disease in a prospective cohort with chronic gastrointestinal complaints, and how S100A12 performs in comparison with established stool markers.
Serum omentin-1 is a novel biomarker for predicting the functional outcome of acute ischemic stroke patients
Authors: Xu Tian , Zuo Peng , Wang Yuqin , Gao Zhiwei , Ke Kaifu
Published: July 2017

Background:

Recent studies have suggested that omentin-1 plays a critical role in the development of cardiovascular disease. However, reported findings are inconsistent, and no study has evaluated the association between omentin-1 levels and a poor functional outcome after ischemic stroke onset.

Methods:

A total of 266 acute ischemic stroke patients were included in this study. All patients were prospectively followed up for 3 months after acute ischemic stroke onset and a poor functional outcome was defined as a major disability or death occurring during the follow-up period. A multivariable logistic model was used to evaluate the association between serum omentin-1 levels and the functional outcome of ischemic stroke patients at 3 months.

Results:

Ischemic stroke patients with poor functional outcome had significantly lower levels of serum omentin-1 than patients without poor functional outcome at the 3-month follow-up (50.2 [40.2–59.8] vs. 58.3 [44.9–69.6] ng/mL, p<0.01). Subjects in the highest tertile of serum omentin-1 levels had a 0.38-fold risk of having poor functional outcome, compared with those in the lowest tertile (p<0.05). A negative association between omentin-1 levels and poor functional outcome was found (p for trend=0.02). The net reclassification index was significantly improved in predicting poor functional outcome when omentin-1 data was added to the multivariable logistic regression model.

Conclusions:

Higher omentin-1 levels at baseline were negatively associated with poor functional outcome among ischemic stroke patients. Omentin-1 may represent a biomarker for predicting poor functional outcome of acute ischemic stroke patients.
Public Participation and Democratic Legitimacy of Rulemaking – A Comparative Analysis
Authors: Rakar Iztok
Published: July 2017

In recent years, public participation has been a frequent object of research, especially in relation to rulemaking procedures. The aim of the paper is to verify a common thesis, that public participation is a means for enhancing democratic legitimacy in rulemaking. In order to do so, the author defines legitimacy and legitimation, presents models of the democratic legitimacy of the executive and compares monistic and pluralistic understanding of democracy. The author then analyzes standpoints of American, English and German legal theory and case law and proposes a possible solution to the main research question.
Questioning the Moral Understanding of Law
Authors: Pavčnik Marijan
Published: July 2017

The primary content-related framework we are bound to are the basic human rights as established in the constitution. These basic rights may change and develop, yet as the heritage of our political and legal culture, they possess such a solid core meaning that only a “dogmatic sceptic” (G. Radbruch) can doubt it. In societies with plural values, the moral values expressed by the basic human rights are the most solid moral basis of law. The moral understanding of law is necessarily accompanied by a moral criticism of law. Such criticism is often not pleasing to the authorities, but it cannot be avoided if one wants to live up to our responsibility towards nature, society and future generations. A lawyer who is not interested in these issues and only sticks to the letter of the law acts in a fossilized manner and does not enrich the life that the law is intended for. Legal thought should always have its meaning, as Smole’s Antigone would say.
Application of Rough Set Theory to Establish the Amount of Waste in Households in Rural Areas
Authors: Szul Tomasz , Knaga Jarosław , Nęcka Krzysztof
Published: July 2017

The method based on rough set theory (RST) was used in the study to establish the rate of mass accumulation of waste in households in rural areas, which are characterised by different economic types, in case of which traditional statistical analyses are usually hardy reliable. The following indicators available in the General Statistical Office’s statistics were used in the analysis: population density, income level, main source of income, economic type of the municipality, area of agricultural land, age of the buildings and participation of gaseous fuels in meeting heat demands. The method shown should not be considered as a competition for statistical methods, but it could complement them, especially in cases when there are few objects to analyse, the more so as it proves useful in cases where input data are general, imprecise and uncertain. As has been shown in the study, with such data and a small number of objects, the relative error of estimation was 13% on average.
