In Situ Bioremediation of a Gasoline‐Contaminated Vadose Zone: Implications from Direct Observations
Authors: Moshkovich Eyal , Ronen Zeev , Gelman Faina , Dahan Ofer 
Published: May 2018

Core Ideas
Controlled infiltration of amended water enhanced bioremediation.
Remediation strategy in contaminated vadose zone was evaluated in real time.
Vadose zone hydrochemical and isotopic properties were monitored in situ.
CSIA was applied to aqueous and vapor phases for attenuation assessment.
In situ bioremediation of a contaminated vadose zone requires implementing hydraulic and chemical conditions that stimulate the development of indigenous bacteria capable of degrading contaminants in the subsurface. We investigated enhanced biostimulation of a gasoline‐contaminated deep vadose zone through nutrient‐ and O2–amended water infiltration. A vadose zone monitoring system (VMS) provided real‐time observations of the treatment process's effect on hydrocarbon attenuation. The VMS data included continuous measurements of variations in water content, concentrations and isotopic compositions of methyl tert‐butyl ether and benzene, toluene, ethylbenzene, and xylene in pore‐water and gas phases, and concentrations of O2 and CO2 in the vadose zone gas phase. Real‐time observations from the unsaturated zone enabled interactive adjustment of the remediation strategy and improved biostimulation conditions for biodegradation of the target compounds. In the course of three infiltration events that included infiltration of an O2– and nutrient‐enriched water solution, a significant reduction in contaminant mass was observed across the unsaturated zone.
GROUNDWATER TIME SERIES
Authors: ERIKSSON ERIK 
Published: May 2018

The term “stochastic hydrology” implies a statistical approach to hydrologic problems as opposed to classic hydrology which can be considered deterministic in its approach. During the International Hydrology Symposium, held 6-8 September 1967 at Fort Collins, a number of hydrology papers were presented consisting to a large extent of studies on long records of hydrological elements such as river run-off, these being treated as time series in the statistical sense. This approach is, no doubt, of importance for future work especially in relation to prediction problems, and there seems to be no fundamental difficulty for introducing the stochastic concepts into various hydrologic models. There is, however, some developmental work required – not to speak of educational in respect to hydrologists – before the full benefit of the technique is obtained.
The present paper is to some extent an exercise in the statistical study of hydrological time series – far from complete – and to some extent an effort to interpret certain features of such time series from a physical point of view. The material used is 30 years of groundwater level observations in an esker south of Uppsala, the observations being discussed recently by Hallgren & Sands-borg (1968).
Promoting a sustainable traditional technique of aquifer water acquisition common to arid lands: a case study of Ghassem Abad Qanat in Yazd Province (Iran)
Authors: Megdiche-Kharrat Fairouz , Ragala Rachid , Moussa Mohamed 
Published: May 2018

Abstract
Qanats are a traditional technique used for aquifer water acquisition and irrigation in dry lands, common to the Middle East. They provide fresh water to communities of users by draining groundwater from aquifers. In Iran, authorities are reporting about 37,000 active qanats contributing about 11% of the country's total groundwater supply. Yazd Province, located in the central part of Iran's plateau, is among the driest regions of the country with more than one million people. It counts 3,193 known qanats with an annual discharge estimated today at about 350 million m3. Ghassem Abad qanat irrigates the agricultural lands of Ghassem Abad village in the Province of Yazd. Its water is managed by an administration headed by a mirab. This paper describes the qanat's mechanism and provides an overview about qanats in Iran. It also promotes, through the study of Ghassem Abad qanat, the related water management system as an example of eco-friendly traditional knowledge leading to social equity and sustainability. It explains how water is distributed to stakeholders (through water shares and irrigation cycles). Nevertheless, and for its survival, the qanat of Ghassem Abad has to continuously deal with social and economic challenges. The farmlands are continuously menaced by urban expansion.

Authors: Kip Heather A. , Kuro Maya , Hami Steven , Nugget Terry , Montre Evan R. 
Published: May 2018

Background:
Galanthum nivalis has been used throughout history for its medicinal properties.
Although traditionally used as an antidote to poison, G. nivalis has also recently been found
to have effects in neurological conditions such as Alzheimer’s Disease and mild cognitive impairment.
Recent studies also suggest that it may have neurological activity that may be beneficial for
psychiatric and neurological disorders like anxiety.
</P><P>
Objective: This study aimed to assess the neurological activity of G. nivalis extract using a behavioral
test of anxiety-like behavior in Syrian hamsters.

Methods:
G. nivalis extract was administered daily to hamsters while undergoing a semi-naturalistic
version of the open field test to assess anxiety. Hamsters were video recorded during their natural
active times beginning an hour before and ending an hour after lights-on and lights-off. Free roaming
behaviors were scored in a 2 x 4 m open pen with enrichment objects for hamsters to interact
with. After 10 days, hamsters were subjected to a social interaction test with a novel conspecific.

Results:
Hamsters receiving G. nivalis extract showed increased time that was spent free-roaming
and a greater proportion of that time was spent moving. They also spent more time interacting with
enrichment objects in the open pen. The social interaction test showed that hamsters receiving G.
nivalis extract spent more time playing with a novel conspecific.

Conclusion:
G. nivalis extract is a neurologically active natural product with behaviorally relevant
effects. It improved anxiety-like behavior in hamsters, as evidenced by increased time free roaming,
moving, and interacting with objects, while improving social interactions.

Artikkelissa kuvataan naisyrittäjien työhyvinvointia ja sen yhteyksiä työhyvinvointia ja liiketoimintaa tukevien palvelujen käyttöön. Tukipalveluina tarkastellaan työterveyshuolto- ja kuntoutuspalveluita sekä Elinkeino-, liikenne- ja ympäristökeskuksen (ELY) tarjoamia koulutusrahoitus-, konsultointi- ja neuvontapalveluita. Tutkimusaineisto (n=128) kerättiin sähköisellä kyselyllä vuosina 2010–2011 naisyrittäjien työhyvinvoinnin ja liiketoimintaosaamisen sekä yrittäjien sijaisjärjestelmän kehittämishankkeessa Keski-Suomessa. Naisyrittäjien työhyvinvointia kuvaavien muuttujien ja tukipalveluiden käytön välisiä yhteyksiä ja niiden tilastollista merkitsevyyttä tarkasteltiin ristiintaulukoimalla ja Fisherin tarkalla testillä. Naisyrittäjät (84 %) olivat omistautuneita työlleen ja tarmokkaita työssään. Heitä kuormitti yleisimmin työn epävarmuus sekä työn keskeytykset ja kiire. Työnantajayrittäjät kokivat stressiä enemmän kuin yksinyrittäjät (p = 0,039). Työterveyshuoltopalvelujen kattavuus oli heikko erityisesti yksinyrittäjien (13 %) keskuudessa, ja kuntoutuspalveluja oli käyttänyt harva naisyrittäjä (11 %). ELY-keskuksen neuvonta- ja yrittäjien koulutuspalvelujen käyttö oli sen sijaan melko yleistä (44 %). Naisyrittäjien psykososiaalisista kuormitustekijöistä työn keskeytyksillä ja kiireellä oli yhteys yrityskohtaistenkonsultointipalvelujen käyttöön (p = 0,024). Työn keskeytyksistä ja kiireestä kärsivät yksinyrittäjät olivat muita yleisemmin työterveyshuoltopalvelujen piirissä (p = 0,029). Työntekijöiden poissaoloista kuormittuneet työnantajayrittäjät olivat järjestäneet muita useammin työterveyshuoltopalvelut työntekijöilleen (p = 0,001). Tutkimuksen tulokset kertovat työterveyshuollon kapeasta roolista naisyrittäjien työhyvinvoinnin tukijana. Työterveyshuollon laajempi hyödyntäminen edellyttää palvelujen saatavuuden, hankinnan ja korvattavuuden kehittämistä. Jatkotutkimusta tarvitaan liiketoimintaa tukevien, yrityskohtaisten palvelujen merkityksestä naisyrittäjien työhyvinvoinnille.

New Bio-Scientific Interpretations of the Eco-Economic Zootehnization of the Romanian Performing Agriculture
Authors: Străteanu Amalia-Gianina , Stan Simona Nicoleta 
Published: May 2018

Abstract
It is known that in all Western European countries, during the 20th century was initiated, developed, applied and consolidated the bio-scientific principle of agriculture zootehnization, so this trend continues in the first two decades of the 21st century. Based of the official data of EUROSTAT, this article presents the concrete situation of the dynamics of the two main livestock productions, respectively milk and meat, using annual data, namely those published in 2016 and 2017. The authors use new bio-scientific arguments to analyze and interpret the concept of agriculture zootehnization, with unprecedented and documented ighlighting of polyvalent and synergistic aspects, between the effective zootechnical practice of the performing agriculture (on the one hand) and the bioeconomic management of animal husbandry (on the other hand). Thus, the authors report the fact that at 21 611 thousand head dairy cows in the EU (excluding the United Kingdom), is collected a production of 138 511 thousand tonnes milk, with a average milk production of 6 409.29 kg / head, of which in the milk industry (Table 3. with those 14 selected countries), the year is obtained, in thousand tons, 30 087 dairy products (milk for consumption, milk powder, butter and cheese). In the same sense, the authors present and analyze the dynamics of meat production from the farm livestock and they find that the annual values for carcass weight in thousands tons are for bovine 6,885, for pigs 22,522 and for sheep 423, which highlights a real zootechnical, genetic and bio-productive potential. We underline that in two synthesis tables, the authors present the numerical situation of the relations between the European Union and Romania, so in a professional way, through a new bio-scientific argument it is justifiably demonstrated that Romania needs to develop inter-, multi-and transdisciplinary and to apply a real country project for the Carpatho-Danubiano-Pontic autochthon space in its European context.
Health literacy of students. Results of an online survey at the Bochum health university (Germany) / Gesundheitskompetenz Studierender – Ergebnisse einer Online-Befragung an der Hochschule für Gesundheit Bochum
Authors: Reick Sibylle , Hering Thomas 
Published: May 2018

Abstract

Background

Health literacy is of growing importance in public health research in Germany. People with good health literacy are likely to make better health decisions. A large proportion of the German population, not just vulnerable groups, has a problematic or insufficient health literacy.

Aims
The study describes the health literacy of students at a German health university. It investigates the influence of sociodemographic and course-related factors on health literacy. The results are compared with those of the general population from Germany.

Methodology
Study participants were recruited by email. 203 students took part in the online survey (response rate 20.2%). From the European Health Literacy Questionaire 16 (HLS-EU-Q16) 127 datasets of students were completely available and were analyzed in this study. In addition to health literacy, sociodemographic and course-related factors were ascertained.

Results
39 (30.7%) of the students have a sufficient or excellent health literacy. On average, health literacy is lower in the group of students of health-related courses (M=30.6) than in the normal German population (M=34.5). The levels are particularly low in the dimensions of appraising and applying of health information.

Conclusion
The results must be interpreted with care. They can be used as a base for long-term monitoring of students’ health literacy and provide starting points for health promotion within the academic setting. Students of health-related degree should be encouraged to reflect on their own and others health literacy, as this is important for their future work with patients or clients.

Authors: Kapilan Natesan , Jullya Naik 
Published: May 2018

Abstract
The biodiesel has lower volatility and is costlier than the fossil diesel. Hence it is necessary to add a low cost fuel which has higher volatility, with the diesel. The tire pyrolysis oil (TPO) produced from waste tire and tubes have these desirable properties and hence in this work, we have mixed TPO with biodiesel to enhance the properties of the biodiesel. The engine tests were carried out on a single cylinder compression ignition engine with the mixture of biodiesel and TPO as fuel. From the engine tests, it is observed that the fuel mixture results in engine performance close to diesel operation at the higher injector nozzle opening pressure.

Published: May 2018

Abstract
The high-strength steels and tailor welded blanks (TWB) are applied in construction of cars parts to reduction of cars weight [1, 2]. The application of these materials brings possible complicatons during the forming when it proves the considerable influence of stress-strain characteristics differences of of the individual parts of TWB what result in non-constant material flow and consequently a negative movement of the weld interface [3, 4]. One of the ways of elimination of this negative effect is to choose a suitable blankholder system with optimal distribution of blankholder forces by using elastic blankholder with adjustable distribution of blankholder forces. Within the bounds of study the experimental blankholder system with elastic blankholder with adjustable distribution of blankholder forces was used [5, 6]. Finite element methods (FEM) simulation has unsubstitutable role n the study of formability of TWB whereby it is possible to determine the values and points of application of the blankholder forces [7, 8]. The FEM simulations results carried out in simulative LS-Dyna software are presented in this article which is focused on achieving weld interface movement minimalization of tailor welded blanks from DP600 and BH220 materials by optimization of blankholder forces [9, 10].
