Published: April 2016

Abstract
For improving the understanding of interactions between hyperspectral reflectance and soil salinity, in situ hyperspectral inversion of soil salt content at a depth of 0-10 cm was conducted in Hetao Irrigation District, Inner Mongolia, China. Six filtering methods were used to preprocess soil reflectance data, and waveband selection combined by VIP (variable importance in projection) and b-coefficients (regression coefficients of model) was also applied to simplify model. Then statistical methods of partial least square regression (PLS) and orthogonal projection to latent structures (OPLS) were processed to establish the inversion models. Our findings indicate that the selected sensitive wavebands for the 6 filtering methods are different, among which the multiplicative signal correction (MSC) and standard normal variate methods (SNV) have some similar sensitive wavebands with unfiltered data. Derivatives (DF1 and DF2) could characterize sensitive wavebands along the scale of VNIR (350-1100 nm), especially the second derivative (DF2). The sensitive wavebands for continuum-removed reflectance method (CR) have protruded many narrow absorption features. For orthogonal signal correction method (OSC), the selected wavebands are centralized in the range of 565-1013 nm. The calibration and evaluation processes have demonstrated the second order derivate filtering method (DF2) combined with waveband selection is superior to other processes, for it has high R
2 (larger than 0.7) both in PLS and OPLS models for calibration and evaluation, by choosing only 156 wavebands from the whole 700 wavebands. Meanwhile, OPLS method was considered to be more suitable for the analyzing than PLS in most of our situations.

Published: April 2016

Abstract
The aim of this paper was to present possibilities of using different substrates to assist the bioremediation of soils contaminated with heavy metals, pesticides and other substances. Today's bioengineering offers many solutions that enable the effective conduct of biological remediation, including both biostimulation and bioaugmentation. For this purpose, they are used to enrich various organic substances, sorbents, microbiological and enzymatic preparations, chemical substances of natural origin or nanoparticles. The use of genetic engineering as a tool to obtain microorganisms and plants capable of efficient degradation of pollutants may cause the risks that entails the introduction of transgenic plants and microorganisms into the environment. In order to determine the efficacy and possible effects of the various bioremediation techniques, it is required to conduct many studies and projects on a larger scale than only in the laboratory. Furthermore, it should be emphasized that bioremediation involves interdisciplinary issues and therefore, there is a need to combine knowledge from different disciplines, such as: microbiology, biochemistry, ecology, environmental engineering and process engineering.
The Potential for Joint Farming Ventures in Irish Agriculture: A Sociological Review
Authors: Cush Peter , Macken-Walsh Áine 
Published: April 2016

Abstract
Joint farming ventures (JFVs) are promoted within Irish and EU policy discourses as strategies that can enhance the economic and social sustainability of family farming. Research has shown that JFVs, including arrangements such as farm partnerships, contract rearing and share farming, can potentially enable farmers to work cooperatively to improve farm productivity, reduce working hours, facilitate succession, develop skills and improve relationships within the farm household. In the context of increasing policy promotion of JFVs, there is a need to make some attempt at understanding the macro socio-cultural disposition of family farming to cooperation. Reviewing sociological studies of agricultural cooperation and taking a specific focus on the Irish contextual backdrop, this paper draws the reader’s attention to the importance of historical legacy, pragmatic economic and social concerns, communicative norms, inter-personal relationships, individualism and, policy and extension stimuli, all of which shape farmers’ dispositions to cooperation and to JFVs specifically.

Published: April 2016

AbstractVitamin D is mainly known for its effects on the bone and calcium metabolism. The discovery of Vitamin D receptors in many extraskeletal cells suggests that it may also play a significant role in other organs and systems. The aim of our study was to assess the relationship between 25(OH)D3levels, lower limb isokinetic strength and maximum oxygen uptake in well-trained professional football players. We enrolled 43 Polish premier league soccer players. The mean age was 22.7±5.3 years. Our study showed decreased serum 25(OH)D3levels in 74.4% of the professional players. The results also demonstrated a lack of statistically significant correlation between 25(OH)D3levels and lower limb muscle strength with the exception of peak torque of the left knee extensors at an angular velocity of 150°/s (r=0.41). No significant correlations were found between hand grip strength and maximum oxygen uptake. Based on our study we concluded that in well-trained professional soccer players, there was no correlation between serum levels of 25(OH)D3and muscle strength or maximum oxygen uptake.

Abstract
This study aimed to evaluate and compare the hydration states prior to different sporting events (training sessions, friendly and official matches) in elite female soccer players and relate that to the importance that the player attached to the hydration state as a determinant of sports performance. The hydration state of 17 female elite soccer players (age: 21.5 ± 3 years; body mass: 62 ± 6 kg; body height: 165 ± 9 cm) was determined by measuring their urine specific gravity (USG) prior to three different sports events: training sessions (PT), friendly (PF) and official (PO) matches. The importance that each player attached to the hydration state as a determinant of sports performance was evaluated through a simple questionnaire. An average of 47.05% of the soccer players were severely dehydrated (USG > 1.030), 33.33% were significantly dehydrated (USG > 1.020), 17.64% were mildly dehydrated (USG > 1.010) and 1.96% were euhydrated (USG < 1.010). The average USG was 1.027 ± 0.007 (PT = 1.029 ± 0.009; PF = 1.023 ± 0.010 and PO = 1.030 ± 0.006). Differences were found between urine specific gravity prior to a friendly and an official match (p = 0.03). No relationship was found between urine specific gravity and the importance each player attached to the hydration state as a determinant of sports performance. The results show that dehydration is the most prevalent hydration state of elite soccer players before training sessions, friendly and official matches. Players were most dehydrated prior to official matches, which was unlinked to the players’ perceived importance of hydration for sports performance.

Abstract
Conventional approaches for simulating steady-state distributions of dilute particles under diffusive and advective transport involve solving the diffusion and advection equations in at least two dimensions. Here, we present an alternative computational strategy by combining a particle-based rather than a field-based approach with the initialisation of particles in proportion to their flux. This method allows accurate prediction of the steady state and is applicable even at intermediate and high Péclet numbers

where traditional particle-based Monte-Carlo methods starting from randomly initialised particle distributions fail. We demonstrate that generating a flux of particles according to a predetermined density and velocity distribution at a single fixed time and initial location allows for accurate simulation of mass transport under flow. Specifically, upon initialisation in proportion to their flux, these particles are propagated individually and detected by summing up their Monte-Carlo trajectories in predefined detection regions. We demonstrate quantitative agreement of the predicted concentration profiles with the results of experiments performed with fluorescent particles in microfluidic channels under continuous flow. This approach is computationally advantageous and readily allows non-trivial initial distributions to be considered. In particular, this method is highly suitable for simulating advective and diffusive transport in microfluidic devices, for instance in the context of diffusive sizing.
Is There Such a Thing as Narrative Explanation?
Authors: Klauk Tobias 
Published: April 2016

AbstractSome narratives are explanatory, and some explanations are given by narrating. But are there explanations which are explanatorySince the concepts of narrative and explanation are contested, both concepts need to be explicated in order to investigate whether narrative explanations exist. As for explanation, the idea that some narratives are explanatory because they are narratives is often expressed by saying that the narrative form contrib­utes to the explanatory force of the explanation. Unfortunately, the notion of explanatory force is but a rather vague picture. It is not entirely clear what a contribution to explanatory force might consist in. After explicating what counts as an explanation, I therefore propose to substitute the notion of explanatory force by a more precise account. The one that is chosen for the purposes of this paper (but not the only possible choice) is van Fraassen’s account: explanations are seen as at least answers to how-questions or why-questions which are relevant for theMy explication of the notion of narrative already stands in this context. In order to find relevance relations between answers to how/why-questions andIn the main part of the paper, these inherently narrative candidates are then identified in the literature on narrative explanation, and I subsequently ask whether they can provide a relevance relation betweenThe last section of the paper then situates these considerations in their historical contexts, starting with Hempel’s theory of explanation. The question is asked why the idea of a special, narrative type of explanation seemed attractive in the first place. I come up with three tentative answers: the widespread discontent with Hempel’s theory of scientific explanation, the availability of narrative as an obvious but allegedly underrated aspect of explanations, and the availability of a list of candidates for which narrative explanation was supposed to work. None of these historical reasons, however, is ultimately conclusive.

Published: April 2016

Abstract

Objective:
The risk of neonatal respiratory morbidity between indicated deliveries vs. spontaneous deliveries has not been consistent in previous studies, in spite of the traditional belief that chronic intrauterine stress might have protective effect on fetal lung maturation. We hypothesized that the heterogeneous etiology of indicated preterm delivery may obscure the relationship between the etiologies of preterm birth and neonatal respiratory morbidity. To address this issue, we divided the indicated preterm birth (PTB) into medically-indicated (without fetal compromise) PTB and maternal/fetal-indicated PTB, and compared the neonatal respiratory morbidity according to the etiology of late PTB.

Study design:
Neonatal respiratory morbidities were examined in neonates who were delivered between 34+0 and 36+6 weeks of gestation according to the etiology of PTB: 1) medically-indicated PTB (but without fetal compromise), 2) maternal/fetal-indicated PTB, or 3) spontaneous PTB such as preterm labor or preterm premature rupture of membranes.

Results:
A total of 710 late preterm neonates were included in the study population, including 31 cases of medically-indicated PTB, 202 cases of maternal/fetal-indicated PTB, and 477 cases of spontaneous PTB. The rate of composite respiratory morbidity in cases of medically-indicated PTB is higher than both maternal/fetal-indicated PTB and spontaneous PTB (19% in medically-indicated PTB, 6% in maternal/fetal-indicated PTB, and 7% in spontaneous PTB). This difference between medically-indicated PTB and maternal/fetal-indicated PTB remained significant after adjustment for confounding variables.

Conclusion:
The medically-indicated PTB is associated with highest risk of neonatal respiratory morbidity in late PTB.
Social insurance in the Second Republic of Poland. Social advantage or the policy of caution
Authors: Chylak Karol 
Published: April 2016

Abstract
Social insurance was conceived from a great thought of the social caution, from the thought of protection of an uncertain future. That thought of caution, during the time of development of social insurance, was implemented by the public entities on the one hand and by the civil activity on the other one. However, the process of creation of the social insurance system in Poland did not represent the policy of caution executed by the state. The only sign of caution could be seen with reference to the insurance associations as there the participants decided whether to enter the system or not whereas the state executed the policy of giving privileges to the certain social groups
Regulating Effect of Asymmetrical Impeller on the Flow Distributions of Double-sided Centrifugal Compressor
Authors: Yang Ce , Liu Yixiong , Yang Dengfeng , Wang Benjiang 
Published: April 2016

AbstractTo achieve the rebalance of flow distributions of double-sided impellers, a method of improving the radius of rear impeller is presented in this paper. It is found that the flow distributions of front and rear impeller can be adjusted effectively by increasing the radius of rear impeller, thus improves the balance of flow distributions of front and rear impeller. Meanwhile, the working conversion mode process of double-sided centrifugal compressor is also changed. Further analysis shows that the flowrates of blade channels in front impeller are mainly influenced by the circumferential distributions of static pressure in the volute. But the flowrates of rear impeller blade channels are influenced by the outlet flow field of bent duct besides the effects of static pressure distributions in the volute. In the airflow interaction area downstream, the flowrate of blade channel is obviously smaller. By increasing the radius of rear impeller, the work capacity of rear impeller is enhanced, the working mode conversion process from parallel working mode of double-sided impeller to the single impeller working mode is delayed, and the stable working range of double-sided compressor is broadened.
The Foot is not an obligatory constituent of the Prosodic Hierarchy: “stress” in Turkish, French and child English
Authors: Özçelik Öner 
Published: April 2016

AbstractThis paper proposes that the presence/absence of the Foot is parametric; that is, contra much previous research (see e. g. Selkirk, Elisabeth (1995). Sentence prosody: intonation, stress and phrasing. In J. Goldsmith (ed.)The handbook of phonological theory. Cambridge, MA: Blackwell. 550–569., Vogel, Irene (2009). Universals of prosodic structure. In S. Scalise, E. Magni, & A. Bisetto (eds.)Universals of language today. Dordrecht: Springer. 59–82.), it is argued here that the Foot is not a universal constituent of the Prosodic Hierarchy; rather, some languages, such as Turkish and French, as well as early child languages, are footless. Several types of evidence are presented in support of this proposal, from both Turkish and French, as well as child English. A comparison of regular (word-final) and exceptional stress in Turkish reveals, for example, that regular “stress” is intonational prominence falling on the last syllable of prosodic words in the absence of foot structure. Both acoustic and formal evidence are presented in support of this proposal, as well as evidence from syntax-prosody interface. The paper also presents evidence for the footless status of French, which, unlike Turkish, is proposed to be completely footless. Several arguments are presented in support of this position, such as the fact that, in French, the domain of obligatory prominence is the Phonological Phrase (PPh), not the Prosodic Word (PWd); in a PPh consisting of several PWds, therefore, nonfinal PWds can surface without any kind of stress or prominence, suggesting that, at least for non-final PWds, one cannot assume stress or foot structure. Finally, the proposal is extended to additional languages, such as those demonstrating Default-to-Opposite Edge stress.

AbstractThe reactions of 5-azido-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde (azidopyrazole) with several classes of organophosphorus reagents: phosphonium ylides, Wittig-Horner reagents, dialkylphosphonates, trialkylphosphites, tris(dialkylamino)phosphanes, triphenylstibane, triphenylarsane, and Lawesson’s reagent are reported. Structural reasoning for the new products was based on compatible analytical and spectral data. The cytotoxic activity of most of the new products was evaluated against human breast carcinoma cell line (MCF7) and human hepatocellular carcinoma cell line(HepG2). Certain tested compounds showed promising results.

Published: April 2016

ObjectivesTo systematically review the incidence and factors associated with recurrences or new tumors after apparent complete resection of pheochromocytoma or thoraco–abdomino–pelvic paraganglioma.DesignA systematic review and meta-analysis of published literature was performed.MethodsPubmed and Embase from 1980 to 2012 were searched for studies published in English on patients with non-metastatic pheochromocytoma or thoraco–abdomino–pelvic paraganglioma, complete tumor resection, postoperative follow-up exceeding 1 month, and recurrence or new tumor documented by pathology, hormonal dosages, or imaging tests. Incidence rates of new events after curative surgery were calculated for each study that had sufficient information and pooled using random-effect meta-analysis.ResultsIn total, 38 studies were selected from 3518 references, of which 36 reported retrospective cohorts from the USA, Europe, and Asia. Patient follow-up was neither standardized nor exhaustive in the included studies. A clear description of patient retrieval methods was available for nine studies and the follow-up protocol and patient flow for four studies. Only two studies used multivariable methods to assess potential predictors of postoperative events.The overall rate of recurrent disease from 34 studies was 0.98 events/100 person-years (95% confidence interval 0.71, 1.25). Syndromic diseases and paragangliomas were consistently associated with a higher risk of a new event in individual studies and in meta-regression analysis.ConclusionsThe risk of recurrent disease after complete resection of pheochromocytoma may be lower than that previously estimated, corresponding to five events for 100 patients followed up for 5 years after complete resection. Risk stratification is required to tailor the follow-up protocol after complete resection of a pheochromocytoma or paraganglioma. Large multicenter studies are needed to this end.

Published: April 2016

BACKGROUND:In the United States, the proportion of Bordetella pertussis isolates lacking pertactin, a component of acellular pertussis vaccines, increased from 14% in 2010 to 85% in 2012. The impact on vaccine effectiveness (VE) is unknown.METHODS:We conducted 2 matched case-control evaluations in Vermont to assess VE of the 5-dose diphtheria, tetanus, and acellular pertussis vaccine (DTaP) series among 4- to 10-year-olds, and tetanus, diphtheria, and acellular pertussis vaccine (Tdap) among 11- to 19-year-olds. Cases reported during 2011 to 2013 were included. Three controls were matched to each case by medical home, and additionally by birth year for the Tdap evaluation. Vaccination history was obtained from medical records and parent interviews. Odds ratios (OR) were calculated by using conditional logistic regression; VE was estimated as (1-OR) × 100%. Pertactin status was determined for cases with available isolates.RESULTS:Overall DTaP VE was 84% (95% confidence interval [CI] 58%–94%). VE within 12 months of dose 5 was 90% (95% CI 71%–97%), declining to 68% (95% CI 10%–88%) by 5–7 years post-vaccination. Overall Tdap VE was 70% (95% CI 54%–81%). Within 12 months of Tdap vaccination, VE was 76% (95% CI 60%–85%), declining to 56% (95% CI 16%–77%) by 2–4 years post-vaccination. Of cases with available isolates, &gt;90% were pertactin-deficient.CONCLUSIONS:Our DTaP and Tdap VE estimates remain similar to those found in other settings, despite high prevalence of pertactin deficiency in Vermont, suggesting these vaccines continue to be protective against reported pertussis disease.
