description: Residues from banana cultivation generates residues lack proper management. The objective of this research was to evaluate the physical properties of banana pseudostem for textile application. Specifically, et species: Musa paradisiaca, Musa sapientum and Musa acuminata. A completely randomized design was applied with three treatments, corresponding with the species under study, carrying out five repetitions for each treatment. The fiber extraction was artisan and followed the next steps: cutting, cleaning and transport (pseudostem), extraction, combing, drying and storage (fibre). The results of the statistical analysis showed that Musa sapientum fiber has the most length (123.34 cm), greater elongation (7.93%), and the highest: resistance (30.52 MPa), linear density (0.070 dtex), when compared with the results of the species M. paradisiaca, and M. acuminata. All the species under analysis had a circular cross section. M. acuminata presented the greatest uniformity in the arrangement of filaments. In addition, the three evaluated species are similar to abaca, ramie and sisal in length and thickness. Finally, it was found that the cost of production of the artisanal extraction of banana fiber requires an approximate investment of $3.60. In conclusion, the fiber obtained from the three of the species studied has appropriate physical properties for textile application.

description: Farmers are increasingly encountering complex challenges which require them to acquire in-depth knowledge of new technologies and best practices to bring about productive and sustainable farming systems. There is a need to update and improve knowledge and skills, particularly for those who have no or low levels of agricultural training. This study focuses on identifying existing and future skills gaps at farmlevel and investigates how knowledge provision and training should be developed and delivered to meet industry needs. This research obtained the views of key stakeholders and farmers around agricultural education provision and future training needs. The methodology combined semi-structured interviews and a farm-level survey. The results identified an immediate need to develop a programme of continuous professional development. The key barriers to training were time, cost and the relevance of training to a farmer’s particular farming system. Attitudes to training impact on the level of engagement with new practices and technologies; therefore the benefits of life-long learning within the sector need to be promoted. Agricultural education providers should develop stronger collaborations with other education providers and key stakeholders to ensure the sector needs are met.

description: Background & Hypothesis: Tension band wiring (TBW) is a common form of fixation for olecranon fractures. More unstable, oblique fractures are thought to not do as well and the more expensive plate fixation is preferred. This study aims to elucidate the limits for which simple olecranon fractures can be safely fixed using a TBW construct.Methods: MIMICS was used to create a 3D model of the ulna from an anonymised CT scan which was exported to SOLIDWORKS for modelling of the TBW construct with creation of fracture lines at the midpoint of the olecranon at 90,75,60 and 45 degrees to the long axis of the ulna. Finite element analysis was carried out using ABAQUS. The model was constrained proximally, and increasing axial loads of 50N, 250N and 500N was applied distally.Results: At axial loads of 50, 250 and 500N, the TBW construct demonstrated good stability with minimal displacement in all axis at all fracture angles. There was a trend towards increased fracture displacement with greater loads. There was an increase in fracture displacement with decreasing fracture angle, most markedly at below 60 degrees. At 500N of axial loading, net displacement was 0.000000183mm for the 90° fracture, 0.0043mm for 75° fracture, 0.0096mm for 60° fracture and 0.0132mm for 45° fracture.Discussion & Conclusion: The tension band wire appears to be stable at loads up to 500N at fracture angles ranging from 45 to 90 degrees. It may be prudent to avoid early loading of more oblique fractures to prevent risk of displacement.

description: Explaining why some species are disproportionately impacted by the extinction crisis is of critical importance for conservation biology as a science and for proactively protecting species that are likely to become threatened in the future. Using the most current data on threat status, population trends, and threat types for 446 primate species, we advance previous research on the determinants of extinction risk by including a wider array of phenotypic traits as predictors, filling gaps in these trait data using multiple imputation, and investigating the mechanisms that connect organismal traits to extinction risk. Our Bayesian phylogenetically controlled analyses reveal that insular species exhibit higher threat status, while those that are more omnivorous and live in larger groups have lower threat status. The same traits are not linked to risk when repeating our analyses with older IUCN data, which may suggest that the traits influencing species risk are changing as anthropogenic effects continue to transform natural landscapes. We also show that non-insular, larger-bodied and arboreal species are more susceptible to key threats responsible for primate population declines. Collectively, these results provide new insights to the determinants of primate extinction and identify the mechanisms (i.e. threats) that link traits to extinction risk.
Innovation Happens Elsewhere, but Where Does Design Happen? Considerations on Design and Participatory Processes in Emerging Information Technologies

description: By taking as departing point the convergence of emerging technologies and their related production practices, this work reflects on design and participatory processes. This contribution tries to highlight how these processes changed from the traditional Information and Software Systems (ISS) context to the emerging one, where technologies are mainly characterized by decentralized and open-ended processes. The paper presents the traditional conception of design as a linear process and problem-solving endeavour and the role that users’ participation has within this frame. It then moves to focus on how design for emergent technologies extends beyond the 'production' phase and on how the distribution of (users-)participants to these technologies intertwine with the endeavour of designing them.

description: This paper examines the ways in which apprentice scientists learn how to work in the laboratory day by day, the hypothesis being that practical learning is part of the process of becoming a scientist. The paper’s theoretical intention is multi-perspective, and unites various approaches: laboratory studies, practice studies, the corporeal turn perspective and that of communities of practice. The paper argues that learning is produced through the bodies of the apprentices. These embed a sociomaterial assemblage of heterogeneous elements, sustaining the collective laboratory work.

description: Finite-${\mathbf Q}$ magnetic instabilities are rather common in frustrated magnets. When the magnetic susceptibility is maximized at multiple-${\mathbf Q}$ vectors related through lattice symmetry operations, exotic magnetic orderings such as vortex and skyrmion crystals may follow. Here we show that a periodic array of nonmagnetic impurities, which can be realized through charge density wave ordering, leads to a rich phase diagram featuring a plethora of chiral magnetic phases, especially when there is a simple relation between the reciprocal vectors of the impurity superlattice and the magnetic ${\mathbf Q}$-vectors. We also investigate the effect of changing the impurity concentration or disturbing the impurity array with small quenched randomness. Alternative realizations of impurity superlattices are briefly discussed.

description: Many drugs possess modified pharmacological and toxicological potentials when administered in the form of their metal complex. All sulfonamides have one free amino group, which offers an extendable chemistry and makes them interesting potential ligand. Sulfapyridine (SPY) is one of the significant members of sulfa family. Sulfapyridine is widely used as an antibacterial, antithy-roid and antidiabetic drug. To look for a modified and alternative of SPY, we synthesize its metal (mercury) complex by chemical root and reflux method and characterized by few spectroscopic techniques like FT-IR, NMR and PL. Powder XRD data of the metal (mercury) complex of SPY is recorded using Rigaku Ultima IV X-ray diffractometer at Department of physics.

description: The purpose of this paper is to examine the financial performance of five pastoral dairy farming systems through the use of financial ratio analysis in the form of the Du Pont model and to determine any differences in the drivers of financial success between systems. The differing level and allocation of resources, or organisational structure, that each farm system adopts was the basis for a test to determine superior competitive advantage. This test was on the premise that if a farm system has a competitive advantage it would exhibit above average performance. While the on-farm competitive strategy is the same for all systems, cost leadership, the organisational design, and the resource configuration differ between farms. There are low-input farms which achieve low cost production through cost control (the numerator effect) and high-input farms which achieve it through improved outputs (the denominator effect). There has been significant debate in New Zealand as to which system is better with discussion focusing often on misleading metrics. The focus on competitive advantage and the rigour provided by the Du Pont model analysis enables a more balanced assessment of the benefits, or not, of intensification on New Zealand farms. The results highlight how misleading commonly used metrics can be. Despite differences in production and operating profit per hectare there is very little difference between return on assets and return on equity between the systems. Of particular interest is the consistency in operating profit margin between systems indicating no loss in operating efficiency as systems intensify. The only exception to this was the more intensive systems in 08/09 when input and output market price relativity was extremely unfavourable. Further research is required to determine if farms switch between systems as input and output market prices change and to explore those farms that are more resilient to such changes.
The Molecular Genetics Testing Lab. On the Fringe of Personhood

description: This article proposes to consider the deterministic potential of genetic testing by confronting the genetic “mystique” portrayed in popular culture (and in certain scientific literature), in which DNA is seen as the soul of the cell and genes as master molecules (Lindee and Nelkin 2004), with molecular genetic testing laboratory practices. We will look at the question of what genetic testing does, that is, the practice of genetic testing itself. The particular molecular testing laboratory we will be looking at tests for genetic markers associated with DSD (Disorders of Sex Development). The testing process reveals a previously invisible component of the body through the aid of technology, and a complex picture unravels regarding the role genes play in being considered “un-well”.

description: We consider (N,r) games of predation with N species and r < N prey and predators, acting in a cyclic way. Further basic reactions include reproduction, decay and diffusion over a regular grid, without a hard constraint on the occupation number per site, so in a "bosonic" implementation. For special combinations of N and r and appropriate parameter choices we observe games within games, that is, different coexisting games, depending on the spatial resolution. As concrete and simplest example we analyze the (6,3) game. Once the players segregate from a random initial distribution, domains emerge, which effectively play a (2,1)-game on the coarse scale of domain diameters, while agents inside the domains play (3,1) (rock-paper-scissors), leading to spiral formation with species chasing each other. As the (2,1)-game has a winner in the end, the coexistence of domains is transient, while agents inside the remaining domain coexist, until demographic fluctuations lead to extinction of all but one species in the very end. This means that we observe a dynamical generation of multiple space and time scales with emerging re-organization of players upon segregation, starting from a simple set of rules on the smallest scale and changed rules from the coarser perspective. These observations are based on Gillespie simulations. We discuss the deterministic limit derived from a van Kampen expansion. The linear stability analysis predicts the number of forming domains, their composition in terms of species; it also explains the instability of interfaces between domains, which drives their extinction; spiral patterns are identified as motion along heteroclinic cycles. The numerical solutions reproduce the observed patterns of the Gillespie simulations including even extinction events, so that the mean-field analysis here is very conclusive, which is due to the specific implementation of rules.

description: Externally designed strategies for improving the farm enterprise and reduce poverty among rural households may not produce desired results. For farm households to adopt economic approaches such as record keeping and management, innovative approaches that are participatory and which build on their indigenous knowledge are better. The value of farm level record keeping has been known for many decades now, yet many farmers in developing countries do not keep records. This paper presents the outcome of using innovative approaches that involved a rural community in a rural Ghanaian community. This research used consultation, village level meetings and participatory approaches to design user-friendly systems. This resulted in systems with which they can cope and which continued after the programme was over. There is the need to improve rural livelihoods by building on indigenous knowledge and using approaches that achieve greater productivity, efficiency, equity, profitability and sustainability. The findings show that rural households are knowledgeable and have the ability to decide on data collection formats that suit their needs.

description: Liquid transportation fuels require costly and time-consuming tests to characterize metrics, such as Research Octane Number (RON) for gasoline. If fuel sale restrictions requiring use of standard Cooperative Fuel Research testing procedures do not apply, these tests may be avoided by using multivariate statistical models to predict RON and other quantities. Here we show that an accurate statistical model for the RON of gasoline and gasoline-like fuels can be constructed by ensuring the representation of key functional groups in the spectroscopic data set are used to train the model. We found that a principal component regression model for RON based on IR absorbance and informed using neat and 134 mixtures of n-heptane, isooctane, toluene, ethanol, methylcyclohexane, and 1-hexene could predict RON for the 10 Coordinating Research Council Fuels for Advanced Combustion Engine (FACE) gasolines and 12 FACE gasoline blends with ethanol within 34.8+/-36.1 on average and 51.2 in the worst case. We next studied the effect of adding 28 additional minor components found in the FACE gasolines to the statistical model, and determined that it was necessary to add additional representatives of the branched alkane and aromatics classes to reduce model error. For example, adding 2,3-dimethylpentane and xylene to the previous model allowed it to predict RON for the 22 target fuels within 0.3+/-4.4 on average and 7.9 in the worst case. However, we determined that the specific choice of fuel in those classes mattered less than ensuring the representation of the relevant functional group. This work builds upon previous efforts by creating models informed by neat and surrogate fuels---rather than complex real fuels---that could predict the performance of complex unknown fuels.

description: We used classical and accelerated molecular dynamics simulations to characterize vacancy-mediated diffusion of cations in Gd$_2$Ti$_2$O$_7$ pyrochlore as a function of the disorder on the microsecond timescale. We find that cation vacancy diffusion is slow in materials with low levels of disorder. However, higher levels of disorder allow for fast cation diffusion, which is then also accompanied by fast antisite annihilation and ordering of the cations. The cation diffusivity is therefore not constant, but decreases as the material reorders. The results suggest that fast cation diffusion is triggered by the existence of a percolation network of antisites. This is in marked contrast with oxygen diffusion, which showed a smooth increase of the ionic diffusivity with increasing disorder in the same compound. The increase of the cation diffusivity with disorder is also contrary to observations from other complex oxides and disordered media models, suggesting a fundamentally different relation between disorder and mass transport. These results highlight the dynamic interplay between fast cation diffusion and the recovery of disorder and have important implications for understanding radiation damage evolution, sintering and aging, as well as diffusion in disorder oxides more generally.

description: We analyze some basic issues associated with Generalized Poisson-Kac (GPK) stochastic processes, starting from the extended notion of the Markovian condition. The extended Markovian nature of GPK processes is established, and the implications of this property derived: the associated adjoint formalism for GPK processes is developed essentially in an analogous way as for the Fokker-Planck operator associated with Langevin equations driven by Wiener processes. Subsequently, the regularity of trajectories is addressed: the occurrence of fractality in the realizations of GPK is a long-term emergent property, and its implication in thermodynamics is discussed. The concept of completeness in the stochastic description of GPK is also introduced. Finally, some observations on the role of correlation properties of noise sources and their influence on the dynamic properties of transport phenomena are addressed, using a Wiener model for comparison.

We establish that the functional derivative estimate is non-trivially sharp, by constructing a sequence $(f_n,0,u^{(n)})$, where for each $n\in\mathbb{N}$, $u^{(n)}:\mathbb{R}\times [0,T]\to\mathbb{R}$ is a solution to the Cauchy problem with zero initial data and nonlinearity $f_n:\mathbb{R}\to\mathbb{R}$, and for which $\sup_{x\in\mathbb{R}} |u_x^{(n)}(x,T)| \geq α>0$, with \[ \lim_{n\to\infty} \left( \inf_{t\in [0,T]} \left( \sup_{x\in\mathbb{R}}|u_x^{(n)}(\cdot , t)| - \mathcal{F}_t (f_n , 0 , u^{(n)}) \right) \right) = 0 . \]

description: A rational Diophantine m-tuple is a set of m nonzero rationals such that the product of any two of them increased by 1 is a perfect square. The first rational Diophantine quadruple was found by Diophantus, while Euler proved that there are infinitely many rational Diophantine quintuples. In 1999, Gibbs found the first example of a rational Diophantine sextuple, and Dujella, Kazalicki, Mikic and Szikszai recently proved that there exist infinitely many rational Diophantine sextuples. In this paper, generalizing the work of Piezas, we describe a method for generating new parametric formulas for rational Diophantine sextuples.

Starting from the full three-dimensional (3-D) Navier Stokes equations, we provide a detailed derivation of (i) the nonlinear one-dimensional (1-D) governing equations of arterial blood flow (Section 2.1), (ii) their theoretical analysis using the method of characteristics from which several pulse wave analysis methods can be derived (Section 2.2), and (iii) their reduction to the linear zero-dimensional (0-D) formulation governing the dynamics of arterial lumped parameters models (Section 2.3). Lastly, we detail the mathematical derivation of all haemodynamics-based pulse wave analysis methods reviewed in the main article, starting from 1-D or 0-D model results (Section 3).

description: We investigate analytically and numerically the nonstationary circuit QED setup in which $N$ independent qubits interact with a single mode of the Electromagnetic field confined in a resonator. We consider the harmonic time modulation of some parameter (atomic transition frequency or the atom-field coupling strength) and derive the unitary dynamics up to the second order in the modulation depth for $N=1$ and $N\gg 1$. It is shown that all the resonant phenomena that occur for modulation frequencies $\sim 2ω_{0}$ (where $ω_{0}$ is the cavity frequency) also occur for the halved frequencies. However, in the latter case the associated transition rates are significantly smaller and the modulation of the coupling strength is less effective. The transition rates are evaluated explicitly and the prospects of employing the second-order resonances in the phenomena related to the dynamical Casimir effect are examined.

description: In Ireland, the trade of milk quota is subject to regional restrictions and a large variation in quota prices between regions has caused some controversy. This article investigates this issue by analysing the functioning of the Irish milk quota exchange market. For this purpose, the economic value of milk quota is estimated using an optimisation framework. The estimated values are then compared to milk quota prices paid at the exchange market. The analysis reveals that quota is undervalued in the border, midlands and west and south-west regions, while milk quota is overvalued in the east and south regions. This implies that farmers in certain regions overpay for additional quota, while other farmers secure good value for their quota investments. The paper concludes by discussing that the identified regional differences are only partly explained by economic and production factors.

description: A completely nonparametric method for the estimation of mixture cure models is proposed. A nonparametric estimator of the incidence is extensively studied and a nonparametric estimator of the latency is presented. These estimators, which are based on the Beran estimator of the conditional survival function, are proved to be the local maximum likelihood estimators. An i.i.d. representation is obtained for the nonparametric incidence estimator. As a consequence, an asymptotically optimal bandwidth is found. Moreover, a bootstrap bandwidth selection method for the nonparametric incidence estimator is proposed. The introduced nonparametric estimators are compared with existing semiparametric approaches in a simulation study, in which the performance of the bootstrap bandwidth selector is also assessed. Finally, the method is applied to a database of colorectal cancer from the University Hospital of A Coruña (CHUAC).

description: В статье рассмотрена новая технология обработки семян, основанная на применении озонированных растительных масел. Описан процесс озонирования растительных масел с целью повышения их биологической активности с использованием специально сконструированного озонатора с автоматическим регулированием концентрации образующихся озонидов. Рассмотрена технология приготовления эмульсий на основе озонированного масла для предпосевной обработки семян. Показано, что при выращивании яровой мягкой пшеницы сорта Злата на опытном поле «Федерального исследовательского центра «Немчиновка» (Московская область) из семян, обработанных перед посевом эмульсией на основе озонированных масел, улучшались показатели структуры урожая (длина колоса, число колосков в колосе, число зерен в колосе, масса зерна с колоса, масса 1000 зерен), увеличивалось содержание белка и клейковины в зерне, а также значительно уменьшалось поражение листьев пшеницы септориозом.

description: Карбамид и аммиачная селитра — наиболее распространенные и применяемые в мире азотные удобрения. Их эффективность в различных почвенно-климатических условиях в настоящее время является одним из наиболее актуальных вопросов. Результаты большого ряда научных исследований однозначно указывают на то, что основными факторами, обусловливающими увеличение потерь аммиака из карбамида, являются: увеличение рН почвенного раствора, повышение температуры окружающей среды, увеличение влажности. Приведены результаты влияния почвенно-климатических факторов на эффективность азотных удобрений: наиболее высокие газообразные потери азота при использовании карбамида на почвах с высоким уровнем рН или низкой емкостью катионного обмена, при рН 7,5 теряется до 45% азота. Высокая температура окружающей среды и почвы также приводит к увеличению потерь азота и снижению эффективности карбамида вследствие ускорения процесса перехода азота из амидной формы в аммонийную. Опытным путем установлено, что при температуре окружающей среды 32°C потери азота достигают 20%. Определено влияние глубины заделки удобрений на количественные потери газообразного азота, снизить их возможно при заделке удобрения на глубину более 7,5 см. Выявлены преимущества и недостатки удобрений и установлены условия, позволяющие снизить газообразные потери азота. Нерациональное соотношение видов азотных удобрений в структуре минерального питания сельскохозяйственных культур приводит к значительным потерям азота, которые могут достигать 40%. Новой и наиболее современной технологией в области эффективности азотного питания является использование ингибиторов, обеспечивающих постепенное высвобождение элементов питания из удобрения. Использование эффективных способов внесения карбамида, правильный выбор форм удобрений, наиболее подходящих под агроклиматические особенности региона, позволят предотвратить увеличение потерь и даже добиться их снижения.

description: A generation, propagation, and transfer of phonon angular momenta are examined on thermal transport in chiral insulative and diamagnetic crystals of $α$-quartz. We found that thermally-driven phonons carry chirality-dependent angular momenta in the quartz crystals and they could be extracted from the quartz as a spin signal. Namely, chirality-induced selectivity of phonon angular momenta is realized in the chiral quartz. We argue that chiral phonons available in chiral materials could be a key element in triggering or enhancing chirality-induced spin selectivity with robust spin polarization and long-range spin transport found in various chiral materials.

description: Статья посвящена актуальной проблеме изучения особенностей обмена цинка в организме молочных коров при скармливании им зеленой массы и силоса козлятника восточного. Экспериментальная и аналитическая часть исследований выполнена в ФГБНУ «Всероссийский научно-исследовательский институт мелиорированных земель» (ФГБНУ ВНИИМЗ), на опытном полигоне, расположенном в центральной части Тверской области. Исследования проводились на коровах черно-пестрой породы с продуктивностью 4600-5000 кг/год молока. Эксперимент проводился на летних и зимних рационах кормления в специальном помещении. Для изучения процессов поедаемости, переваримости и использования питательных веществ различных рационов, процессов обмена в организме коров микроэлементов проведены физиологические опыты по методикам ФГБНУ ФНЦ ВИЖ им. Л.К. Эрнста и ФНЦ «ВИК им. В.Р. Вильямса» и зоотехнический анализ с учетом рекомендаций. В опытах был обеспечен методический принцип единства межгруппового различия и наличия контрольных животных, позволивший получить объективные сравнительные экспериментальные данные и достоверные выводы на основе математической обработки с использованием статистических компьютерных программ. Установлено, что концентрация цинка в молоке практически не зависит от содержания его в корме, изменение рациона кормления не приводит к коренной трансформации метаболизма цинка в организме коров.

description: В статье приводятся результаты исследования биохимического состава шишек хмеля сортов, произрастающих на территории Чувашской Республики. В настоящее время в Государственном реестре селекционных достижений зарегистрировано 12 сортов хмеля, допущенных для возделывания во всех хмелепроизводящих регионах России. По своим параметрам они вполне соответствуют современным требованиям интенсификации производства, имеют высокую продуктивность, достаточно приспособлены к местным природно-климатическим условиям. Хмель — это незаменимый компонент пива. В его шишках содержатся специфические горькие соединения, эфирные масла и полифенолы, без которых невозможно приготовить доброкачественное пиво. Для более полной и объективной оценки пивоваренных качеств изучен биохимический состав шишек по сумме смол, полифенолов и эфирных масел. Знать химический состав шишек хмеля и изменения состава в процессе формирования и созревания шишек важно для создания наиболее продуктивных сортов хмеля с оптимальными пивоваренными качествами. Кроме того, количественное содержание компонентов в шишках определяет сортотип хмеля. Чувашский хмель обладает хорошими пивоваренными качествами и пользуется спросом у пивоваров России. Биохимическая характеристика некоторых сортов Чувашии не уступает чешскому сорту Жатецкий.
