Authors: Ružičková Dominika , Nel André , Prokop Jakub
Published: March 2019

Two new genera and species of Coniopterygidae (Neuroptera) are described and illustrated from mid Cretaceous (Cenomanian) amber of Myanmar. Mulleroconishyalinagen. n. et sp. n., attributed to the Coniopteryginae, bears a unique combination of venation characters and an abdomen without plicatures. The second new genus, attributed to the Aleuropteryginae, i.e. Palaeoconisazarigen. n. et sp. n., displays a unique pattern of crossveins 1m-cua and 2mp2-cua, with the latter crossing the pigmented spot. A check-list of all fossil genera and species of Coniopterygidae is provided.
The complete mitogenome of Helix pomatia and the basal phylogeny of Helicinae (Gastropoda, Stylommatophora, Helicidae)
Authors: Korábek Ondřej , Petrusek Adam , Rovatsos Michail
Published: March 2019

A complete mitochondrial genome of the Roman snail Helixpomatia Linnaeus, 1758 has been sequenced. The length and gene order correspond to that of other available helicid mitogenomes. We used the mitogenome sequence to reappraise the relationships among the four presumed principal groups of the helicid subfamily Helicinae. The results support the idea that the subfamily is divided between two western Palaearctic diversification centres: Iberian Peninsula and western Maghreb in the west, and Anatolia, the Aegean and Caucasus in the east. One group, the tribe Helicini, diversified in the east and the remaining three currently recognised tribes in the west. However, the exact relationships among lineages of the non-Helicini tribes could not be resolved.

Peer-Assisted Learning With Simulation for Examination and Transition Success
Authors: Rossler Kelly L.
Published: March 2019

This article reports how one pilot project explored prelicensure baccalaureate nursing students' perceptions of peer-assisted learning combined with simulation-based education to prepare for and enhance readiness for programmatic exit and national examinations. A convergent parallel mixed-methods study design was used to address the research questions. A nonprobability convenience purposive sample of 17 prelicensure baccalaureate nursing students enrolled in a programmatic synthesis course participated. Findings demonstrate how prelicensure nursing students, despite experiencing varied levels of anxiety, are ready to engage in peer-assisted learning strategies that incorporate simulation-based education to gain additional preparation for both programmatic and licensure examinations. In an era where hospitals are onboarding newly licensed nurses with simulation, hospital educators and specialists in the health care industry can look to the literature on anxiety and teaching preferences to determine opportunities to integrate peer learning and simulation within transition into practice programs.

Public Health Policy Simulation
Authors: Horton Shalonda Estelle Brazzell , Todd Ana T. , Johnson Karen E. , Gaskamp Carol D. , Guillet Nancy , Murray-Chavez Jennifer
Published: March 2019

Background:

Historically, nursing curricula have not offered opportunities for students to develop hands-on political competence. A public health policy simulation can improve students' ability to be change agents for health policy through advocacy.

Method:

The public health policy simulation was a combination of didactic preparation and hands-on application of advocacy training. At the simulation, held at the State Capitol, students visited legislators, gave an oral testimony before a mock hearing committee, and received feedback from legislators.

Results:

In general, students expressed being more knowledgeable and confident about the legislative process, advocacy for public health issues, communication with legislators, and the role of nursing in the public health policy arena. Students reported increased likelihood of advocacy for public health issues.

Conclusion:

Public health policy simulation should be part of nursing curricula to help to create a culture that dictates that public health policy is an integral component of the nursing profession.

Improving Transition to Practice: Integration of Advanced Cardiac Life Support Into a Baccalaureate Nursing Program
Authors: Powers Summer , Claus Nancy , Jones Allison R. , Lovelace Michael R. , Weaver Kendra , Watts Penni
Published: March 2019

Background:

Nursing students often lack the skills and confidence to intervene in the care of a deteriorating patient as they transition into clinical practice. Exposure to these situations is limited during their academic career. Our team sought to address this by embedding American Heart Association (AHA) advanced cardiac life support (ACLS) content into the curriculum and offering certification to senior-level students.

Method:

The senior skills course was redesigned to include education on current AHA ACLS guidelines and skills. ACLS algorithms were introduced and reinforced by mock code labs utilizing rapid cycle deliberate practice and interprofessional simulation. After completion of the semester, students were given the option to be ACLS certified.

Results:

Students and stakeholders reported positively on the ability to certify in ACLS at our institution prior to graduation and reported increased confidence in their ability to manage patients with cardiopulmonary arrest.

Conclusion:

Providing simulated experiences for these clinical situations can reportedly increase confidence and improve preparedness in senior-level BSN students.

Spontaneous rupture of the inferior vena cava (IVC) in the setting of IVC filter thrombosis: case report
Authors: Ludwig Daniel R , Fraum Tyler J , White G Lance , Narra Vamsi R
Published: March 2019

Spontaneous rupture of the inferior vena cava (IVC) is a rare entity. We report a case of a spontaneous IVC rupture associated with IVC filter thrombosis in a patient presenting with severe atraumatic back pain. Computed tomography (CT) identified a retroperitoneal hematoma and suggested IVC thrombosis. Magnetic resonance (MR) imaging confirmed the presence of IVC filter thrombosis and demonstrated a large defect in the infrarenal IVC, with the vessel lumen in free communication with the adjacent hematoma. The patient was managed conservatively and discharged in stable condition. MR imaging played an important role in characterizing the CT findings, which were unclear.

Authors: Wang Anxi , Shen Jian , Yan Leiming , Ren Yongjun , Liu Qi
Published: March 2019

Internet of things (IoT) is used to provide real-time data collection and analysis of the target area by the cooperation of low-cost devices. The authentication towards multiple devices has become the research hot-spot considering of the requirement in real applications. Sensitivity and privacy of data have caused widespread concerns because low-cost devices are neither tamper-proof nor capable of performing public key cryptography efficiently. However, many researchers only focus on the authentication between two devices in the network. They ignore the authentication among group devices attached to one network. In this paper, we propose A Practical Group Authentication Scheme for Smart Devices in IoT. Note that one device group to be authenticated consists of a group of smart devices. The personal digital assistant (PDA) as the group leader controls authentication operations in its group. From the security analysis, our scheme can resist to various attacks. In addition, the performance analysis shows that our scheme has lower computational cost than the existing scheme.
Suivi multiparamétrique de la première désorption thermique de PCB
Authors: Thannberger Laurent , Sangely Matthieu
Published: March 2019

Thermal desorption was pointed out, by several test phase, to be the only way to discard a PCBs contamination in 5000 t of soils. Many parameters were optimized to allow the whole mass of soil to be heated over 250°C, collecting in the same time all the nocuous vapors to ensure environmental safety of the works. Correct handling of all the parameters allowed driving a decay of more than 97 % in the whole mass of soil.

La désorption thermique a été désignée, après différents essais, comme la seule solution technique pour l’élimination de PCB dans 5000 t de terres. De nombreux paramètres ont dû être optimisés afin de porter cette masse à plus de 250°C, tout en collectant les vapeurs nocives pour assurer la sécurité environnementale de l’opération. La maîtrise de tous les paramètres a permis de mener à bien un abattement de plus de 97 % sur l’ensemble de la masse.
Approche géostatistique appliquée à l’évaluation d’un état de pollution des sols dans le cadre d’une session de site industriel
Authors: Garcia Florine , Cornet Christian , Garcia Michel , Mathieu Jean-Baptiste , Dumont Julien
Published: March 2019

This study focuses on the estimation of masses of contaminants in place inside a production site and the quantification of the spatial uncertainty related to the location of these masses. The aim is to provide an assessment of the current soil contamination (current status) before the transfer of the site to another industrial company. The proposed methodological approach relies on geostatistical modeling of the soil contamination by using a simulation method that generates a large number of realistic and equiprobable 3D images of grades for soil contaminants of interest. The images are realistic because they reproduce the grade data and their observed spatial variability. They are equiprobable in that they all have the same probability to represent the actual soil contamination. To assess the soil contamination before the site transfer, the masses of contaminants in place and the associated uncertainty can be estimated from the simulations, for the whole site or by zone. Using the simulations, it can be identified the locations where potential soil contamination sources are likely to be or not found with high enough confidence, and those where the soil contamination is uncertain. The sources of contamination are defined as corresponding to the areas where the vertical accumulation of contaminant mass exceeds some critical threshold above the saturated zone.

Cette étude porte sur l’estimation de masses de polluants en place à l’intérieur d’un site de production et sur la quantification de l’incertitude spatiale quant au positionnement de ces masses. Elle vise à produire un état de la pollution des sols actuelle avant la cession du site à un autre industriel. L’approche méthodologique proposée repose sur une modélisation géostatistique de la pollution des sols en utilisant une méthode dite de simulation qui permet de générer un grand nombre d’images 3D réalistes et équiprobables des teneurs en polluants d’intérêt dans les sols. Les images sont réalistes car elles reproduisent les données de teneur et leur variabilité spatiale observée. Elles sont équiprobables dans le sens où elles ont toutes la même probabilité de représenter l’état de pollution réel des sols. Comme résultats pour établir l’état de pollution du site avant cession, les simulations permettent de calculer la masse de polluants en place et l’incertitude associée, que ce soit sur l’ensemble du site ou par zone, et d’identifier avec confiance les endroits où les sols constituent ou non des sources de pollution potentielles et les endroits où leur niveau de pollution est encore incertain. Les sources de pollution sont définies sous la forme de seuils de dépassement de la masse de polluant cumulée verticalement au-dessus de la zone saturée.

In a context of control of urban sprawl and tensions on land use, brownfield redevelopment is a challenge for the sustainable development of territories. They are indeed land opportunities to develop ambitious territorial projects that are part of a strategy of circular economy.To support public and private actors in the management of their planning development project on degraded land, ADEME provides technical and financial support to all project leaders, especially local authorities, aiming at brownfield redevelopment projects that require decision-making studies and polluted soil remediation.In this framework, more than 110 brownfield redevelopment projects were laureates in the 2010-2016 period.Beyond these macro figures, it is essential to analyze the projects, with a view to developing a technical and economic overview of brownfield redevelopment, whether in terms of pollution management or sustainable urban development, to identify best practices, provide expertise to stakeholders and improve ADEME practices.This paper presents the outcomes of two studies conducted in this perspective.The outcomes will be made available online: https://www.ademe.fr/reconversion-friches-polluees-service-renouvellement-urbain-enseignements-technico-economiques.

Dans un contexte de maîtrise de l’étalement urbain et de tensions sur l’usage des sols, la reconversion des friches constitue un véritable enjeu pour l’aménagement durable des territoires.Dans ce cadre, l’ADEME accompagne les acteurs publics et privés dans la conduite de leurs projets de reconversion de friches polluées qui nécessitent des actions de dépollution. Ainsi, ce sont plus de 110 projets qui ont été lauréats des appels à projets lancés par l’ADEME entre 2010 et 2016.Quel bilan technique et économique peut-on tirer de ces opérations sur les plans de la dépollution et du projet d’aménagement ou de construction qui lui succède ? Quels impacts ces projets ont eu sur les territoires ? Des informations utiles peuvent-elles être mises à disposition des acteurs de la reconversion ? Autant de questions auxquelles le bilan lancé par l’ADEME en 2017 s’est attaché à répondre. Le bilan a été réalisé sur un panel de 95 opérations parmi ces lauréats qui représente près de 492 hectares reconvertis, 90 hectares dépollués, un montant de travaux de dépollution de 217 M€ sur lequel 38 M€ sont financés par l’ADEME. Les projets de reconversion portent sur la construction de 2,8 millions de m2 de surface de plancher de bâtiments dont environ 23000 logements (à 38 % à vocation sociale).Le présent article en présente les principaux résultats, qui sont accessibles de manière détaillés dans le rapport final de l’étude : https://www.ademe.fr/reconversion-friches-polluees-service-renouvellement-urbain-enseignements-technico-economiques.

Published: March 2019

Water samples from twenty water sources (fifteen boreholes and five streams) in Uzuakoli, Nigeria were collected for the period of 6 months covering the dry and rainy seasons to assess the level of contamination. The Microbiological characteristics including heterotrophic counts, coliform counts and physicochemical parameters includes pH, turbidity, dissolved oxygen, calcium, potassium, nitrate, magnesium and phosphate were evaluated using standard methods. The total Heterotrophic counts for the borehole during the dry and rainy season were 8.3 x 103 cfu/ ml and 10.8 x 104 cfu/ ml. The Heterotrophic counts for the stream were 12.7 x 104 cfu/ ml and 17.8x 106 cfu/ ml. The frequency of occurrence of the isolates are Staphylococcus aureus 63% in borehole and 85% in streams, Pseudomonas aeruginosa 49% in boreholes and 95% in streams, Proteus sp 52% in boreholes and 97% in streams, Streptococcus sp 46% in boreholes and 53% in streams, Enterobacter aerogenes 33% in boreholes and 63% in streams, Escherichia coli 16% in boreholes and 53% in streams and Salmonella sp no percentage in boreholes and 40% in streams. The result shows a significant difference at (P≤0.05) for the bacterial isolates. The physicochemical parameters of the borehole and stream water samples during the dry and rainy seasons were determined. The temperature ranged from 25oC 32oC; pH ranged from 5.3 8.1; turbidity ranged 0.03 3.23; dissolved oxygen ranged from 3.45–7.40mg/l; biochemical oxygen demand ranged from 1.20–4.32mg/l; chemical oxygen demand ranged from 2.50–5.21mg/l; Calcium ranged from 0.81–5.64mg/l; potassium ranged from 1.01–4.22mg/l; Nitrate ranged from 1.49–4.02mg/l; magnesium ranged from 0.13–2.20mg/l; phosphate ranged from 0.51–2.01mg/l. The water samples were all within the WHO limits apart from sample from Iyi Agbozu that had temperature of 32oC.

Authors: Guerrero M. Mar , Lacasa Carmen M. , Martínez Victoriano , Martínez-Lluch M. Carmen , Larregla Santiago , Lacasa Alfredo
Published: March 2019

The efficacy of soil biosolarization for the control of Verticillium dahliae and Rhizoctonia solani fungal pathogens was evaluated over two consecutive artichoke crop cycles in southeastern Spain. Soil biosolarization was applied in mid-June for 42 days. The evaluated soil treatments were: fresh sheep manure (FSM); beer bagasse (BB) plus FSM; broccoli crop residues plus FSM; and a control of non-disinfestated and non-amended soil. Different variables were analyzed: i) soil temperature during biosolarization; ii) soil inoculum density of Verticillium before and after biosolarization; iii) infectivity of V. dahliae and R. solani introduced inoculum after biosolarization treatments at 15 and 30 cm soil depth through bioassays; iv) crop disease incidence; and vi) marketable yield. Treatments were randomized in a complete block design with four replicates. Biosolarization treatments reduced levels of both fungal pathogens in both years and had significant lower percentages of affected plants at the end of the crop. All biosolarization treatments significantly improved marketable yield 22-29% to 38-59% compared to the non-disinfestated control in 2015-2016 and 2016-2017 crop cycles respectively. Biosolarization with different organic amendments can be recommended as an effective management strategy for the control of soil-borne fungal diseases in artichoke crops in southeastern Spain, especially in repeated monocultures which are cultivated intensively.
A Benchmarked Evaluation of a Selected CapitalCube Interval-Scaled Market Performance Variable
Authors: Lusk Edward J.
Published: March 2019

Context In this fifth analysis of the CapitalCube™ Market Navigation Platform[CCMNP], the focus is on the CaptialCube Closing Price Latest [CCPL] which, is an Interval Scaled Market Performance [ISMP] variable that seems, a priori, the key CCMNP information for tracking the price of stocks traded on the S&P500. This study follows on the analysis of the CCMNP’s Linguistic Category MPVs [LCMPV] where it was reported that the LCMPV were not effective in signaling impending Turning Points [TP] in stock prices. Study Focus As the TP of an individual stock is the critical point in the Panel and was used previously in the evaluation of the CCMNP, this study adopts the TP as the focal point in the evaluation montage used to determine the market navigation utility of the CCPL. This study will use the S&P500 Panel in an OLS Time Series [TS] two-parameter linear regression context: Y[S&P500] = X[TimeIndex] as the Benchmark for the performance evaluation of the CCPL in the comparable OLS Regression: Y[S&P500] = X[CCPL]. In this regard, the inferential context for this comparison will be the Relative Absolute Error [RAE] using the Ergodic Mean Projection [termed the Random Walk[RW]]  of the matched-stock price forecasts three periods after the TP. Results Using the difference in the central tendency of the RAEs as the effect-measure, the TS: S&P Panel did not test to be different from the CCPL-arm of the study; further neither outperformed the RW; all three had Mean and Median RAEs that were greater than 1.0—the standard cut-point for rationalizing the use of a particular forecasting model. Additionally, an exploratory analysis used these REA datasets blocked on: (i) horizons and (ii) TPs of DownTurns & UpTurns; this analysis identified interesting possibilities for further analyses.
Psychosocial Programmes and Employees Retirement Preparedness: Empirical Evidence From the Educational Sector in Kenya
Authors: Gathiira Titus G. , Muathe Stephen M.A. , Kilika James M.
Published: March 2019

Retirement is a process with employees planning decisions generally focusing on the subjective life expectancy, a mental model of years remaining before one dies. Indeed, the real exit of an individual from a career job is accompanied by changes that include social and psychological, resources leading to variations in an individual’s well-being. The purpose of this study was to assess how employees’ engagement in psychosocial programmes affects their retirement preparedness in the education sector in Kenya. The target population was 1,238 teachers aged 50 years and above and employed in public secondary schools by the Teachers Service Commission in Kirinyaga and Murang’a Counties by 2017. A representative sample of 334 respondents was selected using multistage sampling technique. Data was collected using semi structured questionnaire and interview guide. Logit regression was used to establish the relationships between variables in the study and to test the null hypotheses at P ≤ 0.05 confidence level. The findings indicate that even though the sampled pre-retiree teachers were not adequately prepared for retirement psychosocially, yet their engagement in psychosocial programmes increases their retirement preparedness level. The reported findings extend the current understanding of employee separation programmes and raise implications for the various theories that underpin employee separation decisions in HRM.

Published: March 2019

The effects of an oregano and/or rosemary (Origanum vulgare L. and/or Rosmarinus officinalis L.) dietary supplementation to the diet of fattening pigs were investigated. Thirty-two grower-finisher pigs (45 kg) were divided into four dietary groups identified as: control diet (CTR); CTR+ 0.2% oregano (O); CTR + 0.2% rosemary(R), and CTR+ 0.1% oregano + 0.1% rosemary (OR). During the finishing period, all groups received a further supplementation of 0.5% of conjugated linoleic acids (CLA). Blood samples were collected after an adaptation period of 15 days to the new diet (T1) and at the end of the finishing period (T2) to evaluate antioxidant status (total antioxidant power and reactive oxygen metabolites) and immune responses (lymphocytic phenotyping and IgG levels). Pork meat samples were evaluated for glutathione peroxidase activity (GSHPx), total phenolic content and preference rating. A significant increase in B lymphocytes (CD79+) and a higher IgG level was observed in the R and O groups (P<0.05). Furthermore, there were significant effects of dietary supplementation on meat GSHPx activity and total phenolic contents (P<0.001 and P<0.005, respectively). Preference rating showed that pork derived from group R was the most preferred by the consumers.
Surrealist Presencing in Theophile Gautier’s ‘The Mummy’s Foot’
Authors: Ammari Deema N. , Allawzi Areej K. , Odeh Akram A.
Published: March 2019

This paper attempts to pursue a Surrealist approach to Existential presencing as projected in Theophile Gautier’s ‘The Mummy’s Foot’. The existentialist individual is thrown into an absurd nonsensical world, and is only capable of giving meaning to his existence by distancing himself from society and proving his presence through subjective continuous action, or else risks his reduction to nonexistence. Likewise, the Surrealist aim is to escape the rational limitations of society hindering the individual’s ability to project his full imaginative potential. The only possible way for a Surrealist to truly experience and project his creativity and place in the world is through one’s sub-conscious, only possibly accessed in the dream world, which otherwise is never fully attainable in the waking-state. The paper attempts to offer a fresh perspective as it explores the possibility of tracing existential presencing by utilizing the Surrealist method of dream interpretation in literature. The conjoining of the waking-state and the dream world grants access to the possibility of proving one’s existence in either state, so long as subjective action is affected and continued in both realities.

Authors: Alsawalqah Hamad , Alshamaileh Yazan , Alshboul Bashar , Shorman Areej , Sleit Azzam
Published: March 2019

Productive firms try to deliver high-quality products to be globally competitive. Therefore, software development firms need to adhere to a set of best practices that improve their processes. Capability maturity model integration (CMMI) comprehensively assesses the maturity of a firm's processes. Representing a major departure from the traditional method of running quality management in software development firms, the adoption of CMMI has major ramifications and long-lasting effects on a company’s quality procedures. Unfortunately, the literature lacks information as to how firms should implement CMMI. Our research involved conducting an exploratory study examining the major factors that influenced CMMI adoption for Jordanian software development firms. Quality managers from eighteen software development organizations took an open-ended survey. The results show that the main factors in CMMI implementation in Jordanian software development firms were issues of its being too costly, having no time, dealing with market scope, and lack of top management support. Conclusions are also presented.

Authors: Kumar D. Vasanth , Mohan G. Madhan , Mohanasundaram K. M.
Published: March 2019

Garment Manufacturing is one of the oldest in the world, compromising a high number of critical operations. The main issues in the garment industry are the lead time, production rate, very poor line balancing and fabric wastes. Productivity improvement is carried out by implementing the various lean tools in the industry, such as 5S, Value Stream Mapping (VSM) and line balancing in the sewing section. After the implementation of lean tools in the garment industry, the outcomes observed are a reduction in work-in-progress inventory, increases in the production process and increased line efficiency. Similarly the before and after implementation of 5S, which shows space utilisation in the sewing section, is increased. In this research, an implementation study was conducted in only one organisation. Hence the results extracted by the conduct of this implementation study are achievable and adaptable in similar organisations.

Laboratory Setback Actuators and Explosive Suitability for Gun Launch
Authors: BAKER Ernest
Published: March 2019

There is currently no agreed standard methodology for assessing the suitability of explosives for gun launch or for the determination of acceptance criteria for explosive fill defects. Laboratory setback activator testing has been used as an assessment tool for investigating the suitability of explosives for gun launch. Unfortunately, laboratory setback activator testing is not standardized and large variations exist in activator design, function, and results between different laboratories. However, it is the only currently available tool for assessing an explosives safety and suitability to launch-induced setback forces. In laboratory setback activator tests, ignitions are observed at setback loadings that are much higher than produced in actual gun launched projectiles. This may be related to the defects in actual projectiles, which appear to be very different than the laboratory tests.

Steel of chemical composition Fe-0.58%C-1.80%Si-1.95%Mn-1.3Cr-0.7Mo (weight %), after isothermal heat treatment at 210°C, is characterized by following mechanical properties determined at static tensile test: yield strength YS0.2 = 1.3 GPa; ultimate tensile strength UTS = 2.05 GPa; total elongation E = 12%, hardness 610 HV and Charpy-V impact toughness 24 J at +20℃ and 14 J at -40℃. Stress-strain curves obtained for pre-stressed material before the next dynamic compression and after repeated compressions were analysed. Microstructure of the deformed specimens in areas of the dynamic impact was investigated. The effects of the dynamic repeated impact on changes in characteristics of the investigated material, in that on strain hardening mechanism, were established. Critical strains of 5.3% at strain rate 910 s-1 and about 10% at strain rate 50 s-1 for the nanostructured bainite were determined. Exceeding the critical strain under uniaxial repeated high-strain-rate compression, resulted in decreasing of ability of the steel for further plastic deformation and strain hardening.

The paper presents a system that is a worldwide-unique means designed for building engineering barriers, fitting into the quasi-intelligent battlefield concept. The weapons employed are an innovative solution that integrates acoustic, seismic, thermal and laser scanner sensors into a single quasi-intelligent decision-making system. The system enables deploying a minefield section which, after deactivating 1st and 2nd degree safeties, operate autonomously, selecting targets and eliminating them with an explosively formed projectile. The paper presents the concept of the system's design and results of tests of individual elements.

Anhydrous hydrazine in room temperature is colorless fuming oily liquid with ammonia-like odor. It is used in various industries for electrolytic plating of metals on glass and plastics, as a chemical intermediate for the synthesis of pesticides, insecticides, medicines and days. It is used also as water treatment agent in energy industry (corrosion inhibitor), rocket propellant and as explosives material. Long term exposure to hydrazine may cause to skin irritation and allergic reactions. Diluted aqueous solutions of hydrazine may be irritating for skin, eye and respiratory tract. Epidemiologic studies shows that chronic exposure to hydrazine may cause cancer. In European Union hydrazine is classified as a carcinogenic substance (cat. 1B). Experts from International Agency for Research on Cancer (IARC) have classified hydrazine as a compound probably carcinogenic to humans (Group 2A). Due to decreasing of MAC value for hydrazine in Poland it was necessary to develop and validate a sensitive method for determining hydrazine concentrations in the workplace air in the range from 1/10 to 2 MAC values, in accordance with the requirements of Standard No. PN-EN 482. The study was performed using a liquid chromatograph with spectrophotometric detection. All chromatographic analysis were performed with Discovery LC-18 150 × 2,1 mm analytical column, which was eluted with mixture of acetonitrile and water (6:4 v/v). The method is based on the collection of hydrazine on glass fiber filter impregnated with sulfuric acid, extraction with mixture of sodium dihydrogen phosphate and EDTA, derivatization of extracted compound with benzaldehyde and chromatographic determination of resulted solution with HPLC technique. The method is linear (r = 0.9989) within the investigated working range 0.15–3.5 μg/ml (0.00125–0.029 mg/m3 for a 240-L air sample). Calculated limit of detection (LOD) and limit of quantification (LOQ) were 0.0007 μg/ml and 0.0023 μg/ml, respectively. The average extraction efficiency of hydrazine from filters was 97% and samples stored in refrigerator are stable for 14 days. The analytical method described in this paper enables determination of hydrazine in workplace air. The method is precise, accurate and it meets the criteria for procedures for measuring chemical agents listed in Standard No. PN-EN 482. The method can be used for assessing occupational exposure to hydrazine and associated risk to workers’ health. The developed method of determining hydrazine has been recorded as an analytical procedure (see appendix). This article discusses the problems of occupational safety and health, which are covered by health sciences and environmental engineering.
Pentachlorophenol. Determination in workplace air by means of high performance liquid chromatography
Authors: Brzeźnicki Sławomir , Bonczarowska Marzena
Published: March 2019

Pentachlorophenol (PCF) in room temperature is a crystalline solid with phenol-like odor. It is soluble in most organic solvents (diethyl ether, acetone, carbon tetrachloride, methanol). It is slightly soluble in water. Pentachlorophenol is used as a fungicide, insecticide and as non-selective herbicide (defoliant) in cotton crops. It is also used as antimicrobial agent in leather, paper and textile industry. It has been widely used as wood preservative in wood and construction industry. Occupational exposure to pentachlorophenol may cause irritation of mucous membranes of the eyes and the upper respiratory tract and skin lesions. It may also lead to changes in the central nervous system like headache, insomnia, vertigo and depression. Acute poisoning may cause pulmonary edema, cardio-respiratory disorder and even death. Pentachlorophenol is also suspected to be carcinogenic to humans. The aim of this study was to develop and validate a sensitive method for determining pentachlorophenol concentrations in workplace air in the range from 1/10 to 2 MAC values, in accordance with the requirements of Standard No. PN-EN 482. The study was performed using a liquid chromatograph with spectrophotometric detection. All chromatographic analysis were performed with Zorbax SB-CN 250 × 4.6 mm analytical column, which was eluted with mixture of 0.1% phosphoric acid in acetonitrile and 0.1% phosphoric acid in water (6: 4 v/v). The method is based on the collection of pentachlorophenol on XAD 7 resin preceded by a glass fiber filter, extraction with methanol and chromatographic determination of resulted solution with HPLC technique. The method is linear (r = 0.9997) within the investigated working range 0.625–12.5 μg/ml (0.05–1.0 mg/m3 for a 25-L air sample). The calculated limit of detection (LOD) and limit of quantification (LOQ) were 0.014 μg/ml and 0.048 μg/ml, respectively. The average extraction efficiency of pentachlorophenol from filter and XAD 7 amounted to 95% and samples stored in refrigerator are stable for 14 days. The analytical method described in this paper enables determination of pentachlorophenol in workplace air. The method is precise, accurate and it meets the criteria for procedures for measuring chemical agents listed in Standard No. PN-EN 482. The method can be used for assessing occupational exposure to pentachlorophenol and associated risk to workers’ health. The developed method of determining pentachlorophenol has been recorded as an analytical procedure (see Appendix).

BackgroundThe trajectory of dementia through time is characterized by common transitions which are difficult for persons with dementia (PWDs) and their families and friends. Our study sought to identify determinants for the quality of transition outcomes.MethodA 24-month, prospective, longitudinal design identified specific transitions as they occurred in 108 person-with-dementia/caregiver dyads, and assessed the perceived transition quality from the perspective of the caregiver and what we denote as the ‘summative’ transition quality outcome variable (as explained in the Data Processing section under Methods).ResultsAmong caregivers and during the authors’ deliberations of the summative transition quality outcomes, good transition quality was associated with the PWD’s baseline Disability Assessment for Dementia (OR 1.04, 95% CI 1.02-1.06 per increase in percent score based on summative assessments), and with the PWD’s higher baseline quality of life scores (OR 1.11, 95% CI 1.05-1.18 per increase in unit of score in QOL-AD based on summative assessments). Caregiver-perceived better outcome quality was associated with lower caregiver burden, (OR 0.97, 95% CI 0.95-0.99 per unit CBI score increase).ConclusionIdentifying determinants of successful transitions is feasible and may be translated into practical guidance for use in clinical encounters. Those with worse prior quality of life or worse performance in activities of daily living appear to require specific support during transitions, as do those whose caregivers report higher levels of burden.

Authors: Martin Valdunciel M. Engracia , Cope Jonathan
Published: March 2019

Este ensayo propone cuatro tesis para una agenda de investigación de Estudios Críticos de Biblioteconomía y Documentación (Critical Library and Information Studies. CLIS). El autor argumenta que un compromiso normativo con las bibliotecas como instituciones sociales debería guiar cualquier futura agenda de investigación de CLIS, que las ciencias naturales son un modelo pobre para la investigación de CLIS, que el valor de la neutralidad debería abandonarse y que cualquier proyecto de CLIS debería proponer alternativas.
(Partner) Hunting in Rick Bass’ ‘Antlers’
Authors: Møller Ida Hagh
Published: March 2019

This paper aims to elucidate the proportionality amongst the micro-ideologies within the field that ecocriticism occupies. Through an analysis of Rick’ Bass short story ‘Antlers’ the paper points out and contrasts these micro-ideologies. Moreover, it examines the author’s usage of figurative language including allegory of hunting which the paper argues aims to depict human interrelations in contemporary society. Finally, it argues that the author implicitly advocates anthropocentrism over biologism and that his vision of environmentalism is influenced by his values. Said values are found to be pronounced in his fiction as well as his nonfictional accounts.
The Crosslinguistic Influence of First and Second Language on Third Language Acquisition
Authors: Helms Kirsten Lindegaard
Published: March 2019

This paper explores the crosslinguistic influences of first and second language on third language acquisition. While it has earlier been argued that Universal Grammar is lost with subsequent language acquisition, some studies indicate that Universal Grammar is not lost and is also applied when acquiring other languages. By drawing on two studies of third language acquisition where the third languages are V2, it is shown that when it comes to acquiring a third language, transfer can happen from both the first and second languages. One study showed that both the first and second languages can influence the acquisition of a third language while another argued in favor of the second language being the most dominant influence. On the basis of an examination of different theoretical approaches to language transfer, this paper argues that the Typological Primacy Model provides the most convincing and pragmatic explanation in that language transfer depends on linguistic circumstances.
