Energy and Memory Efficient Data Loss Prevention in Wireless Sensor Networks
Authors: Hejazi Pooya , Ferrari Gianluigi
Published: July 2018

Load balancing, energy efficiency and fault tolerance are among the most important data dissemination issues in Wireless Sensor Networks (WSNs). In order to successfully cope with the mentioned issues, two main approaches (namely, Data-centric Storage and Distributed Data Storage) have been proposed in the literature. Both approaches suffer from data loss due to memory and/or energy depletion in the storage nodes. Even though several techniques have been proposed so far to overcome the mentioned problems, the proposed solutions typically focus on one issue at a time. In this paper, we integrate the Data-centric Storage (DCS) features into Distributed Data Storage (DDS) mechanisms and present a novel approach, denoted as Collaborative Memory and Energy Management (CoMEM), to overcome both problems and bring memory and energy efficiency to the data loss mechanism of WSNs. We also propose analytical and simulation frameworks for performance evaluation. Our results show that the proposed method outperforms existing approaches in various WSN scenarios.

Published: July 2018

The proposed research methodology aims to design a generally implementable framework for providing a house owner/member with the immediate notification of an on-going theft (unauthorized access to their premises). For this purpose, a rigorous analysis of existing systems was undertaken to identify research gaps. The problems found with existing systems were that they can only identify the intruder after the theft, or cannot distinguish between human and non-human objects. Wireless Sensors Networks (WSNs) combined with the use of Internet of Things (IoT), Cognitive Internet of Things, Internet of Medical Things, and Cloud Computing are expanding smart home concepts and solutions, and their applications. The primary objective of the present research work was to design and develop IoT and cloud computing based smart home solutions. In addition, we also propose a novel smart home anti-theft system that can detect an intruder, even if they have partially/fully hidden their face using clothing, leather, fiber, or plastic materials. The proposed system can also detect an intruder in the dark using a CCTV camera without night vision facility. The fundamental idea was to design a cost-effective and efficient system for an individual to be able to detect any kind of theft in real-time and provide instant notification of the theft to the house owner. The system also promises to implement home security with large video data handling in real-time.

Published: July 2018

Obesity and metabolic disorders can be risk factors for the onset and development of neurodegenerative diseases. The aim of the present study was to investigate the protective effects on dysmetabolism and neurodegeneration of a natural dietary supplement (NDS), containing Curcuma longa, silymarin, guggul, chlorogenic acid and inulin, on the brains of high fat diet (HFD)-fed mice. A decreased expression of FACL-4, CerS-1 and CerS-4, reduced cholesterol concentration, increased IR expression and insulin signaling activation, were found in brains of NDS-treated HFD mice, suggesting that NDS is able to prevent brain lipid accumulation and central insulin resistance. In the brains of NDS-treated HFD mice, the levels of RNS, ROS and lipid peroxidation, the expression of p-ERK, H-Oxy, i-NOS, HSP60, NF-kB, GFAP, IL-1β, IL-6, and CD4 positive cell infiltration were lower than in untreated HFD mice, suggesting antioxidant and anti-inflammatory effects of NDS. The decreased expression of p-ERK and GFAP in NDS-treated HFD mice was confirmed by immunofluorescence. Lastly, a lower number of apoptotic nuclei was found in cortical sections of NDS-treated HFD. All these data indicate that NDS exerts neuroprotective effects in HFD mice by reducing brain fat accumulation, oxidative stress and inflammation and improving brain insulin resistance.
Pseudopterosin Inhibits Proliferation and 3D Invasion in Triple Negative Breast Cancer by Agonizing Glucocorticoid Receptor Alpha
Authors: Sperlich Julia , Teusch Nicole
Published: July 2018

Pseudopterosin, produced by the sea whip of the genus Antillogorgia, possesses a variety of promising biological activities including potent anti-inflammatory effects. However, few studies examined pseudopterosin in the treatment of cancer cells and, to our knowledge, the ability to inhibit triple negative breast cancer (TNBC) proliferation or invasion has not been explored. Thus, we evaluated the as yet unknown mechanism of action of pseudopterosin: Pseudopterosin was able to inhibit proliferation of TNBC. Interestingly, analyzing breast cancer cell proliferation after knocking down glucocorticoid receptor α (GRα) revealed that anti-proliferative effects of pseudopterosin were significantly inhibited when GRα expression was reduced. Furthermore, pseudopterosin inhibited invasion of MDA-MB-231 3D tumor spheroids embedded in an extracellular-like matrix. Remarkably, the knockdown of GRα in 3D tumor spheroids revealed increased ability of cells to invade the surrounding matrix. In a co-culture, encompassing peripheral blood mononuclear cells (PBMC) and MDA-MB-231 cells, production of interleukin 6 (IL-6) and interleukin 8 (IL-8) significantly increased compared to monoculture. Notably, pseudopterosin proved to block cytokine elevation, representing key players in tumor progression, in the co-culture. Thus, our results reveal pseudopterosin treatment as a potential novel approach in TNBC therapy.

Published: July 2018

Wearable sensors for human physiological monitoring have attracted tremendous interest from researchers in recent years. However, most of the research was only done in simple trials without any significant analytical algorithms. This study provides a way of recognizing human motion by combining textile stretch sensors based on single-walled carbon nanotubes (SWCNTs) and spandex fabric (PET/SP) and machine learning algorithms in a realistic applications. In the study, the performance of the system will be evaluated by identification rate and accuracy of the motion standardized. This research aims to provide a realistic motion sensing wearable products without unnecessary heavy and uncomfortable electronic devices.
Novel Plasmonic Modes of Monolayer MoS$_2$ in the Presence of Spin-Orbit Interactions
Authors: Tao Z.H. , Dong H.M. , Duan Y.F. , Huang F.
Published: July 2018

We investigate on the plasmons of monolayer MoS2 in the presence of spin-orbit interactions (SOIs) under the random phase approximation. The theoretical study shows that two new and novel plasmonic modes can be achieved via inter spin sub-band transitions around the Fermi level duo to the SOIs. The plasmon modes are optic-like, which are very different from the plasmon modes reported recently in monolayer MoS2, and the other two-dimensional systems. The frequency of such plasmons increases with the increasing of the electron density or the spin polarizability, and decreases with the increasing of the wave vectors q. Our results exhibit some interesting features which can be utilized to the plasmonic and terahertz devices based on monolayer MoS2.

Published: July 2018

Carbon concrete PAN/lignin-based CF composites are a new promising material class for the building industry. The replacement of the traditional heavy and corroding steel reinforcement by carbon fiber (CF) based reinforcements offers many significant advantages: a higher protection of environmental resources because of lower CO2 consumption during cement production, a longer lifecycle and thus muss less damage in structural components and a higher degree of design freedom because lightweight solutions can be realized. However, due to cost pressure in civil engineering, completely new process chains are required to manufacture CF based reinforcement structures for concrete. The article describes the necessary process steps in order to develop CF reinforcement: (1) the production of cost-effective CF using novel carbon fiber lines, (2) the fabrication of CF rebars with different geometry profiles. It was found that PAN/lignin-based CF is currently the most promising material in order to meet the future market demands. However, significant research needs to be undertaken in order to improve the properties of lignin-based and PAN/lignin-based CF, respectively. The CF can be manufactured to CF-based rebars using different manufacturing technologies which have been developed on prototype level in this study.

ISSUES IN ASSESSMENT OF POTENTIAL RADON HAZARD AT BUILDING SITES
Authors: Ryzhakova N. K. , Stavitskaya K. O. , Udalov A. A.
Published: July 2018

High concentrations of radon in the premises leads to a risk of lung cancer for the population. In this regard, in the production of design and construction works, an assessment is made of the potential hazard of radon in the construction sites. At the present, the unified approach to methodology of assessment is not developed. Abroad, various categorical and numerical values, such as radon potential or radon index, are used as criteria for radon hazard. In different countries, these criteria are determined using various parameters: uranium / radium concentration, radon volumetric activity in soil air and premises, gas permeability of soils, geological structure of underlying rocks, dose rate of gamma radiation. Studies conducted abroad show that the parameters used, as a rule, do not correlate with the amount of radon entering buildings during its operation. In the Russian Federation, the radon flux density measured on the soil surface is used to estimate the potential radon hazard of a building site. Applied today method of potential radon hazard assessment has one general drawback. It is low reliability of results. Such a quality of assessments obtained by measuring the radon flux density is due to the variability in the values of this value and to the measurement of the surface of the soil. The paper discusses the results of measuring the radon flux density obtained by the methods of «accumulation chambers» and «carbon adsorbers» in the summer periods of 2014, 2016 and 2017. It was confirmed that the strongest influence on the values and variability of radon flux density is exerted by precipitation. The paper presents the results of radon flux density measurements on the soil surface, as well as on the surface of dense loams lying at depths of 0.5 m and 1.5 m. It is shown that the radon flux density measured on the soil surface is two to three times smaller than the values of this value measured on the surface of dense rocks. It is important to note that the lowest variability of the results (20%) was observed in 2014, when measurements were made on the surface of dense loams during dry, stable weather.

Authors: Delyagin W. M. , Aksyenova N. S. , Doktorova N. M.
Published: July 2018

Relevance. The bicuspid aortic valve (BAV) can be combined with genetic developmental syndromes, but the pediatric aspects of the problem have not been adequately studied. Goal. Determine the frequency of BAV from the data of the ultrasound examination rooms (ultrasound) and characterize the clinical and echocardiographic aspects of the bicuspid aortic valve. Material and methods. 19 patients with BAV (17 children and 2 adults) were examined. To evaluate the possible long-term consequences of BAV, 45 adults were examined: men 25 (mean age 61.72 ± 1.42 years), women 20 (mean age 64.9 ± 1.46 years). Results. The frequency of BAV according to the ultrasound examination rooms is 1 case per 20 000-23 500 studies. BAV was combined with genetic syndromes of connective tissue dysplasia (hypermobility syndromes of joints, Marfan, FreemanSheldon, etc.), registered in twins. The average value of the eccentricity index of the BAV leaflets was 3.5, the standard deviation was 1.1, the standard error was 0.274. In adult patients with BAV, calcification of the valves was observed, which was not detected in the control group (p = 0.006). Conclusion. BAV can be both an accidental finding, and be combined with another pathology. BAV is more often found in people with hereditary developmental syndromes. The presence of BAV requires the exclusion of genetic developmental syndromes. Despite the comparative rarity of BAV in the general population, a remote prognosis may be serious, which requires the pediatrician to organize interdisciplinary interaction.

Published: July 2018

A quality drug is central to the success of any therapeutic plan. The quality of drug is determined right from the collection to delivery to the patients. The commonest problem involving the medicinal plant stating materials is intentional or unintentional substitution and adulteration owing to multiple reasons like unavailability, higher costs, unfair trade etc. This trend was also present in the olden days, as evident from the concept of substitute drugs (Pratinidhi Dravya) as available in Yogratanakara, Bhavaprakasha and Bhaishajyaratnawali. Therefore, Charka and later Acharyas also have dealt with authentication and standardization of herbal drugs and formulations in detail by using four Pramanas (tools of knowledge) Ch.Vi.8/87. Nowadays the concept of substitution is entirely converted into intentional and unintentional malpractices of adulteration. The established authenticity parameters for plant material identification and standardization like organoleptic, physical, chemical and genetic parameters are relatively inaccessible for routine use. Not withstanding the accuracy and usefulness of these lab parameters and delay in the development of easy to perform parameters for reasonable drug authentication. These adulteration malpractices spoils the market of herbal industries. In this article we discuss about concept of substitution in ancient Ayurveda and at present intentional and unintentional adulteration practices.

A Fall Risk mHealth App for Older Adults: Development and Usability Study (Preprint)
Authors: Hsieh Katherine L , Fanning Jason T , Rogers Wendy A , Wood Tyler A , Sosnoff Jacob J
Published: July 2018

BACKGROUND

Falls are the leading cause of injury-related death in older adults. Due to various constraints, objective fall risk screening is seldom performed in clinical settings. Smartphones offer a high potential to provide fall risk screening for older adults in home settings. However, there is limited understanding of whether smartphone technology for falls screening is usable by older adults who present age-related changes in perceptual, cognitive, and motor capabilities.

OBJECTIVE

The aims of this study were to develop a fall risk mobile health (mHealth) app and to determine the usability of the fall risk app in healthy, older adults.

METHODS

A fall risk app was developed that consists of a health history questionnaire and 5 progressively challenging mobility tasks to measure individual fall risk. An iterative design-evaluation process of semistructured interviews was performed to determine the usability of the app on a smartphone and tablet. Participants also completed a Systematic Usability Scale (SUS). In the first round of interviews, 6 older adults participated, and in the second round, 5 older adults participated. Interviews were videotaped and transcribed, and the data were coded to create themes. Average SUS scores were calculated for the smartphone and tablet.

RESULTS

There were 2 themes identified from the first round of interviews, related to perceived ease of use and perceived usefulness. While instructions for the balance tasks were difficult to understand, participants found it beneficial to learn about their risk for falls, found the app easy to follow, and reported confidence in using the app on their own. Modifications were made to the app, and following the second round of interviews, participants reported high ease of use and usefulness in learning about their risk of falling. Few differences were reported between using a smartphone or tablet. Average SUS scores ranged from 79 to 84.

CONCLUSIONS

Our fall risk app was found to be highly usable by older adults as reported from interviews and high scores on the SUS. When designing a mHealth app for older adults, developers should include clear and simple instructions and preventative strategies to improve health. Furthermore, if the design accommodates for age-related sensory changes, smartphones can be as effective as tablets. A mobile app to assess fall risk has the potential to be used in home settings by older adults.
Interlocking directorates and different power forms: An explorative analysis in the Italian context
Authors: Esposito De Falco Salvatore , Cucari Nicola , Di Franco Federica
Published: July 2018

The purpose of the present paper is twofold. The first is to update the contribution by Drago et al. (2011) about cross-shareholdings and interlocking directorates in Italian listed companies (FTSE MIB) to 31 December 2016 and to reinforce theory of enlarged collusion. The second is to find how interlocking directorates can contribute to understanding the power structure. By using the social network analysis, we map the network structure of interlocking boards and employ centrality measures like degree, eigenvector and betweenness centrality along with the network density and average degree. We interpret eigenvector centrality as a measure of “effective power” of the connections because it can be seen as a weighted sum of not only direct connections but indirect connections, while betweenness centrality as a measure of “potential power” because it is a proxy of the volume of information that passes through the nodes. In this way, we provide a framework for selecting Italian firms with effective and potential power – around whom interactions and processes can be traced and analysed. In addition, we find that the position assumed by the controlling group of the Mediobanca Galaxy is definitely downsized.
Processing and mechanical characterization of Al2O3/Ni and Al2O3/C0 composites by pressureless sintering of nanocomposite powders
Authors: Kafkaslioğlu Yildiz , Yilmaz Hüseyin , Tür Yahya
Published: July 2018

Al2O3/Ni and Al2O3/Co nanopowder mixtures (with 3 vol.% of metallic phase)
were synthesized by heterogeneous precipitation method. In order to increase
the green strength, polypropylene carbonate (PPC) was used as a binder while
preparing green compacts. Uniaxially pressed powder mixtures were sintered
at 1550?C for 2 h in a reducing atmosphere. The effects of Ni and Co
nanophases on the microstructure and mechanical properties of Al2O3 ceramics
were studied by X-ray diffraction, scanning electron microscopy, Vickers
indentation technique and three-point bending tests. The metallic phase
hindered the densification of alumina matrix, yet hardness values of Al2O3,
Al2O3/Ni, and Al2O3/Co composites were comparable. Vickers fracture
toughness results indicate that the composites have higher fracture
toughness, but the characteristic flexural strength and Weibull modulus are
higher for the pure Al2O3.
La sociologie contre le socialisme dans l'oeuvre d'Emile Durkheim
Authors: Mladenovic Ivica
Published: July 2018

L?article analyse la comprehension du socialisme par Emile Durkheim, telle
qu?elle a ete exposee dans plusieurs articles academiques et dans un livre
publie apres sa mort. Durkheim a en effet etudie cette question profondement
et passionnement pendant les annees 1895-1896 dans le cadre d?un cours sur
le socialisme qu?il donnait a l?Universite de Bordeaux. Dans la premiere
partie de cet article, nous essayons de definir ce classique de la
sociologie scientifiquement ainsi qu?ideologiquement, au vu du contexte
sociohistorique de la Troisieme Republique, qui a, sans aucun doute,
principalement influence ses interets intellectuels majeurs. Dans la
deuxieme partie, nous analysons l?approche durkheimienne du socialisme qui a
ete dans une large mesure influencee par des facteurs non scientifiques, a
savoir, les tentatives du sociologue pour defendre son projet politique ?du
solidarisme? et de critiquer les paradigmes politiques concurrents. Au
centre de sa critique se trouve le socialisme qui, a la fin du dix-neuvieme
siecle, etait en pleine ascension, non seulement en tant que mouvement
politique, mais egalement en tant que source de connaissance. A tel point
que plusieurs intellectuels confondaient le socialisme et la sociologie, ce
qui etait particulierement genant pour le sociologue. De plus, on souligne
le fait que Emile Durkheim ne respecte pas dans son analyse du socialisme
les stricts criteres scientifiques, qui sont d?ailleurs introduits en
sociologie par lui-meme, de sorte que sa sociologie joue en meme temps un
double role: scientifique et d?ideologie politique.

INTRODUÇÃO: Um método de avaliação rápida e eficaz do desenvolvimento da linguagem oral é a utilização de checklists. OBJETIVO: O objetivo do estudo foi desenvolver um instrumento (checklist) para identificação precoce de crianças com risco para desenvolver alterações de linguagem oral ou que já apresentam sinais dessas alterações. MÉTODOS: O processo para a elaboração do checklist foi dividido nas seguintes etapas: etapa 1 - análise (preparação de uma versão prévia para ser analisada por fonoaudiólogos juízes), etapa 2 - revisão (adequação do checklist), etapa 3 - avaliação por usuários e juízes e etapa 4 - finalização. RESULTADOS: O checklist desenvolvido neste estudo foi denominado “Checklist para Identificação de Crianças com Risco ou Indícios Clínicos para Alteração de Linguagem- CICRICAL”. O instrumento foi dividido em duas partes: a primeira contemplou os aspectos relacionados à presença de fatores de risco e a segunda os principais marcos do desenvolvimento linguístico. Na etapa 1, oito juízes analisaram a versão prévia do checklist e a maioria considerou que o instrumento possuía informações claras e conteúdo adequado ao objetivo pretendido. A partir da análise das respostas, o checklist foi reformulado (etapa 2), tendo sido inserido um Manual de Aplicação e algumas informações adicionais. A versão reformulada foi avaliada pelos mesmos fonoaudiólogos que analisaram a versão preliminar e também por profissionais da saúde e educação (etapas 3 e 4). CONCLUSÃO: O “Checklist para Identificação de Crianças com Risco ou Indícios Clínicos para Alteração de Linguagem - CICRICAL” desenvolvido foi considerado um instrumento pertinente, abrangente, claro e relevante.

Authors: Cruz Ana Carolina Almendra , Momensohn-Santos Teresa Maria
Published: July 2018

Introdução: A habilidade auditiva de resolução temporal é caracterizada pela percepção de silêncio entre sons apresentados em função do tempo. Os idosos ouvintes normais e usuários de aparelho de amplificação sonora individual (AASI) necessitam de intervalos de tempo maior que jovens ouvintes normais para perceber o intervalo de silêncio entre os sons. Objetivo: Investigar a influência do uso de aparelho de amplificação sonora individual na habilidade de resolução temporal de um grupo de idosos. Método: A amostra foi composta por 40 idosos portadores de perda auditiva neurossensorial, simétrica de grau leve, moderado e severo bilateralmente que receberam seu par de AASI por meio do programa de saúde auditiva. Foram aplicados os testes do mini exame do estado mental (MMSE), teste de detecção de intervalo de silêncio aleatório (RGDT) e questionário Internacional de Avaliação dos Aparelhos de Amplificação Sonora Individual (QI-AASI). Os dados foram coletados com 15 e 90 dias de uso do AASI. Resultados: Comparando os resultados do teste RGDT antes e depois do uso de AASI observou-se melhora no desempenho dos idosos. No entanto, as variáveis: sexo, idade, desempenho cognitivo e satisfação do uso de AASI não foram estatisticamente significantes para a melhora nos resultados do teste RGDT. Conclusão: O uso de AASI em idosos, por si só foi eficiente na melhora do desempenho da habilidade auditiva de resolução temporal.

A mudança da pirâmide etária brasileira, com o aumento da população idosa, é um aspecto que se evidencia ao longo dos anos. A Instituição de Longa Permanência para Idosos (ILPI) pode ser um equipamento social como possível alternativa para o cuidado de algumas pessoas que envelhecem. Neste contexto, pode-se encontrar na formação de grupos, o fortalecimento do sujeito frente às adversidades em prol de uma melhor qualidade de vida, a qual pode se dar por meio da realização de atividades à promoção da saúde. Este trabalho tem o objetivo de descrever aspectos relativos às atividades em grupo de idosos de uma ILPI do sul do país. Foram realizadas atividades semanais com 20 idosos residentes na ILPI, totalizando 12 encontros. Pode-se observar predomínio do sexo masculino. As ações foram realizadas por meio de rodas de conversa, cantigas e confecção de materiais em conjunto, sendo parte das ações com enfoque ao aspecto lúdico. Buscou-se realizar a estimulação cognitiva, da comunicação, expressividade e do convívio social. Ao longo dos encontros observou-se crescente motivação dos residentes no envolvimento do que era proposto, bem como a aproximação dos profissionais da ILPI com as condutoras das atividades. A atuação fonoaudiológica se deu ao ampliar o olhar além do aspecto técnico, mas voltado à promoção da saúde do idoso.

Published: July 2018

Controlled water use is an important component of sustainable fresh-cut vegetable production because of limited water resources, and also for controlling the quality of wastewater re-used in vegetable processing or for irrigating on fields. In our study the water consumption in vegetable processing plants varied from 1.5 to 5.0 m3 t-1 of finished product. In one plant, monitored over three years, almost 90% of water was used for washing and rinsing of vegetables, but more than 90% of the organic load of the wastewater was generated from the processing stage. The results including organic load and the microbial quality of the wastewaters showed that the wastewater should be treated beforere-use.Separate treating of wastewaters from processing stage is recommended.  Pre-treatment of wastewater using precipitation chemicals and sedimentation in basins decreased the organic load and total solids in the water, allowing further treatment of the waters.

The study was conducted to evaluate an appropriate inclusion level of locally produced unprocessed or expander-processed coloured flowered faba bean (FB) (cv. ‘Kontu’) seeds in diets for laying hens. Egg production and egg quality variables were determined with 560 hens (Lohmann Selected Leghorn, LSL Classic) in a 40-week continued experiment. The hens were fed one of the five diets containing soybean meal as the main protein source. A diet without FB was served as a control diet. Both unprocessed and expander-processed FB was tested either in proportions of 50 g kg-1 or 100 g kg-1 in the diet. Faba bean inclusion (control vs. FB diets) had no effect on the egg production rate, egg mass production, feed consumption, or feed conversion ratio, but it decreased egg weight (p<0.05). Dietary FB inclusion tended to increase the mortality of the hens (p<0.10). Faba bean processing had no effects on egg production parameters or hen mortality. Daily egg mass production decreased and feed conversion ratio increased when FB proportion increased (from 50 to 100 g kg-1, p<0.05). Faba bean inclusion had no effects on egg exterior quality. It can be concluded that 50 g kg-1 of the FB studied (cv. ‘Kontu’) can be used in the diets of laying hens (LSL Classic) without negative effects on production performance or livability.

Meat quality traits for Holstein–Friesian (HF), Norwegian Red × Holstein–Friesian (NR) and Jersey × Holstein–Friesian (JE) cattle reared to slaughter as two genders (bulls and steers) and 2 slaughter weights (570 kg and 640 kg) were compared. Adipose tissue from JE was more yellow (p<0.05) than HF or NR which were similar. There was no difference between breeds and no breed-related interactions for chemical composition, cook loss or instrumental tenderness of longissimus thoracis et lumborum muscle (LT). When adjusted for differences in lipid concentration, LT from NR-sired animals tended to be less red (p=0.058) and LT from JE-sired animals had a lower hue (p<0.05). Substitution of NR or JE for HF sires in the dairy herd will not have important effects on LT characteristics in the production systems examined but the more yellow carcasses from JE-sired cattle may limit their suitability for markets with a carcass fat colour specification.

We applied gypsum (CaSO4×2 H2O) amendments to 100 m2 plots within two clay-textured fields, one under shallow cultivation to 10 cm depth and the other ploughed to 20 cm depth. Unamended plots and plots subjected to a CaCO3 (finely ground limestone) application served as controls. Separate soil monoliths (30 cm in diameter, 40 cm in depth) were collected for laboratory rainfall simulations from all plots 7, 19 and 31 months after the initial application of the amendments. Water passed through the monoliths during these simulations was analysed for turbidity, dissolved and particulate phosphorus (DRP and PP), nitrogen species, dissolved organic carbon (DOC), as well as dissolved Ca2+, Mg2+, K+ and S, pH, and electrical conductivity (EC). Over the three-year monitoring period, gypsum amended soils exhibited substantial decreases in turbidity (45%), PP (70%), DRP (50%) and DOC (35%) relative to control samples. The effects gradually decreased with time, and after 31 months gypsum effects on P species were detectible, but no longer statistically significant. We consider gypsum amendments as a potential tool for slowing P loss from agricultural areas with high P loss potential.

We aimed at assessing establishment risk for 25 arable weed species in a changing European climate for the period 2051–2080. An increase (0.3–46.7%) in the range size was projected for the 14 species and a decrease (1.2–67.4%) for the 11 species in a future climate. The inclusion of the land use data increased the explanatory power of the models. The greatest increases in range sizes were projected for Amaranthus retroflexus, Papaver hybridum and Fumaria parviflora, and declines for Sinapis arvensis, Cerastium semidecandrum and Chenopodium rubrum. Application of a more severe climate scenario (HadCM3A2) affected decline (0.5–18.5%) for 12 species and increase (2.2–31.5%) for 13 species in the range size projections compared with the less severe (HadCM3B2) scenario. Both model scenarios projected high percentage species loss in Mediterranean and temperate Europe, but high species gain in the Alps, Carpathians and in boreal Europe. The results suggest that even under moderate climate scenarios drastic changes in the weed establishment risk can be expected to take place in Europe in the future.

The growing popularity of horse keeping is accompanied by an increase of phosphorus (P) and faecal micro-organisms from outdoor paddocks. We used an indoor rainfall simulation to monitor  concentrations of dissolved reactive P (DRP) and faecal coliforms in runoff and percolation water from different paddock footings. Drainage water was also monitored from two paddocks constructed of woodchips. Sand retained more DRP (p<0.0001) and coliforms from percolation water than woodchips. Some of the footings were amended with P-sorbing materials, such as [Ca(OH)2], [Fe2(SO4)3], or Fe-gypsum, to retain DRP. High DRP concentrations (17–18 mg l-1) were observed in runoff from a woodchip footing amended earlier with Ca(OH)2 and in sand footing amended with CaCO3. However, application of Fe-gypsum to woodchips decreased the DRP load in percolation water by 83% compared to the footing without Fe-gypsum. Fe compounds were better than Ca compounds. The decrease in coliforms was usually small due to the modest pH changes in the water.

An experiment was conducted to compare a bunker silo sealing system comprising an oxygen barrier film (OB: 45μm thickness) with protective woven polypropylene with one comprising standard black polyethylene film (S; 125μm thickness) with protective tyres. Analysis of samples taken to 30 cm depth after 365 days of storage showed no differences in pH or lactic acid between the two sealing systems. There were no differences in aerobic bacterial count between silages. Whilst 2.56 log10 CFU moulds g-1 fresh weight were found in samples of silage sealed with S, no moulds were found in samples of silage sealed with OB. Aerobic stability, averaged 249 hours and 184 hours for OB and S, respectively. The OB system probably inhibited the development of the micro-organisms responsible for the initiation of aerobic deterioration to a greater extent than the standard silo sealing system.
The estimated nutritive value of three common grassland species at three primary growth harvest dates following ensiling and fractionation of press-cake
Authors: McEniry Joseph , O'Kiely Padraig
Published: July 2018

In a Green Biorefinery processing green biomass one possible application for the press-cake fraction is as a feedstuff for ruminants. This study investigates the effects of ensiling and fractionation on the estimated nutritive value of three grassland species harvested at different stages of maturity. Perennial ryegrass (Lolium perenne L., var. Gandalf), cocksfoot (Dactylis glomerata L., var. Pizza) and red clover (Trifolium pratense L., var. Merviot) were grown in field plots and harvested and ensiled in laboratory silos. These silages were subsequently fractionated into press-cake and press-juice fractions. Loss of soluble, fermentable organic matter during ensiling increased the relative proportions of fibre and crude protein. Fractionation resulted in the substantial reduction of herbage soluble nutrient and mineral content, increasing the fibre content and reducing digestibility and crude protein. The low energy and protein content of the press-cake fraction, especially at later harvest dates, will limit its use in ruminant diets.
