Effect of Irrigation and Fertilization Levels on Mineral Composition of Cannabis sativa L. Leaves
A field experiment was conducted in central Greece to study the effect of two irrigation (I1: 100% ETo, I2: 60% ETo) and N-fertilization levels (N1: 244, N2: 184 kg ha-1), on the nutrients concentration of Cannabis sativa leaves (cv. âFibranovaâ). The N, K, Ca, Mg, P -concentration in the leaves was ranged by 2.8 to 3.51%, 1.8 to 2.57%, 1.96 to 2.17%, 0.86 to 0.88%, and 0.3 to 0.37% respectively, while by the micronutrients the iron showed the highest concentration that ranged by 129 to 139.8 mg kg-1dw. The treatment I1F1, where the highest level of irrigation and N -fertilization was applied, compared to the other treatments, showed the highest dry biomass yield, however, in the leaves the highest concentrations of N, K, Mn and Cu were not observed. Moreover, it was found that the N, K, Ca, Mg, P and Fe removal only by one ton dry biomass of leaves was ranged by 28 to 35.12 kg, 18.01 to 25.65 kg, 19.6 to 21.7 kg, 8.34 to 8.75 kg, 3.01 to 3.70 kg and 0.129 to 0.140 kg, respectively. These results could contribute optimal fertilizer application and therefore to the reduction of production costs of the crop
The evolution of labour law in the new member states of the European Union : 1995-2005 - country studies on Cyprus and Malta
This Report traces the development of Labour Law and the implications for Industrial Relations, as well as social and employment policy more generally, in the two small Mediterranean countries of Cyprus and Malta during the period 1995â2005. This period was particularly important for the two countries as it coincided with their efforts for accession to the European Union (EU) and the process of harmonisation with the Acquis Communautaire. Since their independence in 1960 and 1964 respectively for Cyprus and Malta, successive Governments in each country â working with the social partners â had sought to steer a policy of social cohesion to underpin their development efforts. Whilst these strategies were successful in fostering a long period of economic growth and peaceful labour relations, a major outcome was the existence of relatively inflexible labour markets. Liberalisation and globalisation of international markets, coupled with the pressure exerted by the accession process, which required the implementation of the Acquis Communautaire necessitated a series of changes with far reaching implications in social and economic affairs. Naturally the framework of Labour Law â and labour practices thereof â came under increasing pressure to adapt and reform. The Executive Summary describes the main aims and objectives of the Report on the evolution of Labour Law in Cyprus and Malta in the period 1995-2005, and provides an outline of the component chapters. Specifically the Report is divided into three chapters. The first and second chapters consist of the individual Reports on Cyprus and Malta respectively. These constitute the main body of the Report and investigate the evolution of Labour Law in the two countries separately and the implications for Industrial Relations, employment and social policy. The third chapter provides a concluding overview of the two countriesâ experiences and an evaluation of the state of implementation of the Acquis Communautaire in the fields examined.peer-reviewe
Synthesis and electrochemical study of CoNi2S4 as a novel cathode material in a primary Li thermal battery
The authors acknowledge support and contribution from AWE Plc for this work, and thank the STFC for neutron diffraction beam-time.In this work CoNi2S4 was investigated as a candidate cathode material for Li thermal batteries. The CoNi2S4 was synthesized by a solid state reaction at 550âŠC in a sealed quartz tube. Neutron powder diffraction was utilized to confirm normal spinel structure up to 200âŠC, however, there was cation disorder above this temperature. The electrochemical properties of the batteries were investigated at 500âŠC by galvanostatic discharge to elucidate the mechanism and the products NiS, Co3S4 and Co9S8 of the discharge mechanism were confirmed using powder X-ray diffraction. CoNi2S4 exhibits two voltage plateaus vs Li13Si4 at 500âŠC, one at 1.75 V and the second at 1.50 V. CoNi2S4 has an overall capacity of 318 mA h gâ1 from OCV 2.58 V to 1.25 V vs Li13Si4 which is comparable to that of the well-known metal disulfidesPublisher PDFPeer reviewe
Zirconium trisulfide as a promising cathode material for Li primary thermal batteries
In this work ZrS3 has been synthesized by solid state reaction in a sealed quartz tube and investigated as a candidate cathode material in Li thermal batteries. The structure of ZrS3 before and after cell testing has been studied using powder X-ray diffraction. A new spinel related material, LiZr2S4, has been identified as the product of the electrochemical process, which can be indexed to a = 10.452(8) Ă
cubic unit cell. The electrochemical properties of the batteries were investigated at 500 °C against Li13Si4 by galvanostatic discharge and galvanostatic intermittent titration technique (GITT). In a thermal Li cell at 500 °C a single voltage plateau of 1.70 V at a current density of 11 mA/cm2 was achieved with capacity of 357 mA h g-1. Therefore ZrS3 material has some promise as a cathode for Li thermal batteries.Publisher PDFPeer reviewe

Receiving support to quit smoking and quit attempts among smokers with and without smoking related diseases: Findings from the EUREST-PLUS ITC Europe Surveys
Introduction: Having a chronic disease either caused or worsened by tobacco smoking does not always translate into quitting smoking. Although smoking cessation is one of the most cost-effective medical interventions, it remains poorly implemented in healthcare settings. The aim was to examine whether smokers with chronic and respiratory diseases were more likely to receive support to quit smoking by a healthcare provider or make a quit attempt than smokers without these diseases. Methods: This population-based study included a sample of 6011 adult smokers in six European countries. The participants were interviewed face-to-face and asked questions on sociodemographic characteristics, current diagnoses for chronic diseases, healthcare visits in the last 12 months and, if so, whether they had received any support to quit smoking. Questions on smoking behavior included nicotine dependence, motivation to quit smoking and quit attempts in the last 12 months. The results are presented as weighted percentages with 95% confidence intervals (CI) and as adjusted odds ratios with 95% CI based on logistic regression analyses. Results: Smokers with chronic respiratory disease, those aged 55 years and older, as well as those with one or more chronic diseases were more likely to receive smoking cessation advice from a healthcare professional. Making a quit attempt in the last year was related to younger age, high educational level, higher motivation to quit, lower nicotine dependence and having received advice to quit from a healthcare professional but not with having chronic diseases. There were significant differences between countries with smokers in Romania consistently reporting more support to quit as well as quit attempts. Conclusions: Although smokers with respiratory disease did indeed receive smoking cessation support more often than smokers without disease, many smokers did not receive any advice or support to quit during a healthcare visit
Extent and correlates of self-reported exposure to tobacco advertising, promotion and sponsorship in smokers: Findings from the EUREST-PLUS ITC Europe Surveys
Introduction: Tobacco advertising, promotion, and sponsorship (TAPS) are known to promote tobacco consumption and to discourage smoking cessation. Consequently, comprehensive TAPS bans are effective measures to reduce smoking. The objective of this study was to investigate to what extent smokers are exposed to TAPS in general, and in various media and localities, in different European countries. Methods: A Cross-sectional analysis of national representative samples of adult smokers in 2016 from Germany, Greece, Hungary, Poland, Romania, and Spain (EUREST-PLUS Project, n=6,011), as well as England (n=3,503) and the Netherlands (n=1,213) (ITC Europe Surveys) was conducted. Prevalence of self-reported TAPS exposure is reported by country, and socio-economic correlates were investigated using logistic regression models. Results: Self-reported exposure to TAPS varied widely among the countries, from 15.4 % in Hungary to 69.2 % in the Netherlands. In most countries, tobacco advertising was most commonly seen at the point of sale, and rarely noticed in mass media. The multivariate analysis revealed some variation in exposure to TAPS by sociodemographic factors. Age showed the greatest consistency across countries with younger smokers (18-24-year-olds) being more likely to notice TAPS than older smokers. Conclusions: TAPS exposure tended to be higher in countries with less restrictive regulation but was also reported in countries with more comprehensive bans, although at lower levels. The findings indicate the need for a comprehensive ban on TAPS to avoid a shift of marketing efforts to less regulated channels, and for stronger enforcement of existing bans
Transition metal chlorides NiCl2, KNiCl3, Li6VCl8 and Li2MnCl4 as alternative cathode materials in primary Li thermal batteries
Special thanks to AWE Plc for their support and funding for this work. The authors would also like to acknowledge the EPSRC Platform Grant EP/K015540/1 and the Royal Society Wolfson Merit Award WRMA 2012/R2.Transition metal chlorides KNiCl3, Li6VCl8 and Li2MnCl4 were synthesized by solid state reaction in sealed quartz tubes and investigated as candidate cathode materials along with NiCl2 in Li thermal batteries. The structure and morphology were studied and electrochemical properties probed at high temperatures (400°Câ500°C) against Li13Si4 by galvanostatic discharge and galvanostatic intermittent titration technique (GITT). All the transition metal chlorides reduced to metal and the products of the discharge mechanism were confirmed by powder X-ray diffraction. NiCl2 was tested at 500°C and a capacity of 360 mAhgâ1 was achieved. KNiCl3 was tested at different current densities from 15 mA/cm2 to 75 mA/cm2 and a high voltage profile 2.30V was achieved at 425°C with a capacity of 262 mAhgâ1. Li6VCl8 was tested at 500°C and a 1.80V voltage plateau at a current density of 7.5 mA/cm2 was achieved with a capacity of 145 mAhgâ1. Li2MnCl4 was tested at the same current density at 400°C and a capacity of 254 mAhgâ1 was achieved. These transition metal chlorides exhibit higher voltage against Li13Si4 and, hence, provide more specific power compared to the well-known metal disulfides MS2 (M = Fe, Co, Ni) and may be promising cathode materials for Li thermal batteries.Publisher PDFPeer reviewe
Characteristics and correlates of electronic cigarette product attributes and undesirable events during e-cigarette use in six countries of the EUREST-PLUS ITC Europe Surveys
Introduction: This study assessed characteristics and correlates associated with e-cigarette product attributes and identified correlates of experiencing undesirable events during e-cigarette use among adult smokers across six European Union (EU) Members States (MS) prior to the implementation of the Tobacco Products Directive (TPD) in 2016. Methods: We conducted a cross-sectional survey with a nationally representative sample of adult cigarette smokers from six EU MS (Germany, Greece, Hungary, Poland, Romania, Spain) reporting e-cigarette use; randomly selected through a multistage cluster sampling design from June to September 2016. Stepwise logistic regressions were used to identify factors associated with use of flavors, noticing health warnings, mixing e-liquids, experiencing 'dry puff', e-liquid leaking during use and e-liquid spilling during refill. Results: Current daily or weekly prevalence of e-cigarette use among this sample of adult smokers was 7.5%. The most common attributes of e-cigarettes used included those that are flavored, contain nicotine, and are of tank style. Noticing health warnings on e-cigarette packaging and leaflets, respectively, was low (10.2% and 28%, respectively). Use of e-liquid refill nozzle caps, described as easy for a child to open, was associated with spilling during refill (OR=6.73; 95% CI: 2.02-22.37). Participants who adjusted occasionally or regularly the power (voltage) or temperature of their e-cigarette had greater odds of ever experiencing a 'dry puff' (OR=6.01; 95% CI: 2.68-13.46). Mixing different e-liquids was associated with leaking during use (OR=7.78; 95% CI: 2.45-24.73) and spilling during refill (OR=8.54; 95% CI: 2.29-31.88). Conclusions: Ongoing evaluation of factors associated with e-cigarette attributes and of the correlates of experiencing e-cigarette undesirable events during use, related to product design, is crucial to monitoring the impact of the implementing Acts of the EU TPD
