Controlled Deposition of Polyamide Nanofibers Through an Innovative Electrospinning Device

Electrospinning is a straightforward, cheap and unique method to produce novel fibers with diameter in the range of 100 nm and even less. Those nanofibers have a wide variety of applications such as: filters, membranes, composite reinforcement, drug delivery, protective barriers, sensors, wound dressings and tissue-engineered scaffolds where their unique properties contribute to product functionality. However, this process is characterized by a chaotic oscillation of the electrospinning jet which leads to the formation of beads an uneven nanofiber. This research work envisages the development of an apparatus to control the deposition of electrospun nanofibers through the use of a series of charged metal rings and the addition of a secondary power source, which enables a greater control over the polymer jet stream.

Genetic diversity within and among populations of Diprion pini (Hym., Diprionidae) determined by random amplified polymorphic DNA‐polymerase chain reaction of haploid males

Abstract: Based on haploid males, random amplified polymorphic DNA (RAPD) markers were used to study genetic variation within and among four French populations and one Finnish outgroup population of the common pine sawfly, Diprion pini (L.), representing a severe European forest pest associated with mass outbreaks. Taking into account that all multilocus haplotypes were detected, a total of 140 individuals were completely discriminated by means of 17 polymorphic markers (present or absent), which were amplified from nine selected random‐decamer primers. All populations shared the same genetic types, but pronounced population‐specific frequency distributions were found, indicating that on average 84% of the present genetic variation exists within populations and the remaining smaller part counts for interpopulational variation. The haplotype differentiation registered was able to distinguish between the class of lowland populations and the class of highland populations. Reproductive isolation and therefore limited altitudinal gene flow, indicated in case of a French highland population by an enlarged number of fixed markers, and hitchhiking effects with respect to selective processes at certain loci following local adaptation and speciation are discussed to explain the population structures found. A possible selection is indicated by five markers, showing significantly different frequency distributions between the class of highland populations and the class of lowland populations.
Sustainable practices for Pest and Disease management of Horticultural crops

The traditional practices, commonly known as indigenous technical knowledge (ITK) were ecological friendly, cost effective and were mostly suited for the particular situation. Painting of citrus trunk with lime against citrus trunk borer, pouring fresh milk on the crown of coconut against rhinocerous beetle, application of salt or salt solution against crown rot of coconut, smoking in the evening under mango trees against different pests, placing banana in the potato field against red ant, sparying of fish wash on vegetable crop against aphids were some of most commonly practices used by the farmers of different villages of Lakhimpur, Assam.
Visualizing climate change: an exploratory study of the effectiveness of artistic information visualizations

Artists creatively use scientific data in artistic information visualizations (AIVs) to address climate change. Yet, it is unclear how effective they are in making viewers consider climate change as important. To assess their reception, this research studies and compares AIVs in relation to four additional visual forms, which are common in the communication of climate change (information visualizations, news photos, digital art visuals and cartoons). Qualitative research consisting of a short survey, q-sort and semi-structured interviews was employed. Some AIVs were judged clearer and more agreed with than other AIVs, suggesting that a less abstract AIV style might be more suitable. In comparison to the other visual forms, the artistic information visualizations were the least effective in making viewers consider climate change as important. It appears that artists’ free choice of data focus and artistic styles faces limits when depicting a complex topic such as climate change. A need for clarity or accompanying descriptions to the visualizations, at least when targeted at the general public without art training, might be necessary. The study did not show distrust in art’s involvement in the climate change discourse.
Constrained RGBD-SLAM

SUMMARY This paper introduces a new RGBD-Simultaneous Localization And Mapping (RGBD-SLAM) based on a revisited keyframe SLAM. This solution improves the localization by combining visual and depth data in a local bundle adjustment. Then, it presents an extension of this RGBD-SLAM that takes advantage of a partial knowledge of the scene. This solution allows using a prior knowledge of the 3D model of the environment when this latter is available which drastically improves the localization accuracy. The proposed solutions called RGBD-SLAM and Constrained RGBD-SLAM are evaluated on several public benchmark datasets and on real scenes acquired by a Kinect sensor. The system works in real time on a standard central processing units and it can be useful for certain applications, such as localization of lightweight robots, UAVs, and VR helmet.

cGMP Binding to Noncatalytic Sites on Mammalian Rod Photoreceptor Phosphodiesterase Is Regulated by Binding of Its γ and δ Subunits*

The binding of cGMP to the noncatalytic sites on two isoforms of the phosphodiesterase (PDE) from mammalian rod outer segments has been characterized to evaluate their role in regulating PDE during phototransduction. Nonactivated, membrane-associated PDE (PDE-M, αβγ2) has one exchangeable site for cGMP binding; endogenous cGMP remains nonexchangeable at the second site. Non-activated, soluble PDE (PDE-S, αβγ2δ) can release and bind cGMP at both noncatalytic sites; the δ subunit is likely responsible for this difference in cGMP exchange rates. Removal of the δ and/or γ subunits yields a catalytic αβ dimer with identical catalytic and binding properties for both PDE-M and PDE-S as follows: high affinity cGMP binding is abolished at one site (K D >1 μm); cGMP binding affinity at the second site (K D ∼60 nm) is reduced 3–4-fold compared with the nonactivated enzyme; the kinetics of cGMP exchange to activated PDE-M and PDE-S are accelerated to similar extents. The properties of nonactivated PDE can be restored upon addition of γ subunit. Occupancy of the noncatalytic sites by cGMP may modulate the interaction of the γ subunit with the αβ dimer and thereby regulate cytoplasmic cGMP concentration and the lifetime of activated PDE during visual transduction in photoreceptor cells.
Reproductives and eggs trigger worker vibration in a subterranean termite

Abstract In insect societies, the presence of reproductives or eggs has been shown to shape several biological traits in the colony members. Social interactions are one of these traits that involve modification of the communication system of the entire colony. Many studies described the role of chemical compounds and dominance behaviors in the presence of reproductive but vibratory behaviors received very few investigations. Yet, vibratory behaviors are ideal candidates, particularly for subterranean species like termites, as they could be quickly transmitted through the substrate and could be very diversified (origin, modulation). Here, we investigated whether the presence of reproductives/eggs affects the vibratory behavior (body‐shaking) of workers in the subterranean termite Reticulitermes flavipes. Our results reveal that the presence of reproductives or eggs triggers an increase of workers' body‐shaking, independent of their colony of origin after 24 hr. We hypothesize that vibratory communication could be used to transfer information about the presence of reproductives and eggs to the entire colony, suggesting that vibratory behaviors could serve as an important yet neglected mediator of social regulation.
Executive Function in Infants and Toddlers Born Low Birth Weight and Preterm

Infants born low birth weight (LBW) and preterm were evaluated in a high-risk follow-up clinic and compared with infants born full term. A multivariate linear model was used to examine the overall differences on Bayley Scales of Infant Toddler Development (BSID-III) among three groups: full term, heavy LBW (<2,500 g ≥2,000 g), light LBW (<2,000 g). Results indicated no significant differences in BSID-III scores between the groups. The BSID-III was used to extrapolate indicators of executive function (EF) components. Dimensions of Mastery Motivation (DMQ 18) was correlated with the EF components. Findings showed that both LBW groups scored significantly lower than the full-term group on the EF components which include attention, plan/organize, working memory, and inhibit. Implications for research is discussed.
Legitimating the standard-setter of public sector accounting reforms

ABSTRACT This paper shows how the Brazilian Treasury has developed strategies to build legitimacy in a civil law context where the legislature left a vacuum regarding the accrual accounting standard-setting mandate. While the accounting ‘rule-enforcers’ neglected to require compliance with the rules, the ‘rule-makers’ co-operated with each other to build normativity for accounting rules and eventually attempted to develop new forms of enforcement, which the ‘rule-appliers’ lobbied against. IMPACT Brazil is not the only civil law country that has committed with international organizations to implement accrual accounting IPSAS and prepare whole of public sector accounts. The findings of this paper will be of value to policy-makers from other civil law countries in dealing with the assimilation of new accounting rules in a context of conflict between standard-setters and auditors.
Cutaneous myiasis caused by Dermatobia hominis in Thai travelers: first report in Thailand

Abstract Background: Myiasis is the infestation with fly larvae in live vertebrate hosts. The disease has not been reported in Thailand. Method and Results: We report the first case series of cutaneous myiasis caused by Dermatobia hominis in two Thai travelers who visited Brazil. Two of five travelers were infested with D. hominis larvae. Both presented with furuncular lesions. Surgical excision was performed for both patients and the larvae were removed. They were identified as second stage of D. hominis. Sequence data of both mitochondrial and nuclear genes of the larva were similar to previous reports from Brazil. Conclusion: With increasing travel into endemic countries of D. hominis, physician should be aware of this parasitic infestation.
Improved Convergence Speed of a DCD-Based Algorithm for Sparse Solutions

To solve a system of equations that needs few updates, such as sparse systems, the leading dichotomous coordinate descent (DCD) algorithm is better than the cyclic DCD algorithm because of its fast speed of convergence. In the case of sparse systems requiring a large number of updates, the cyclic DCD algorithm converges faster and has a lower error level than the leading DCD algorithm. However, the leading DCD algorithm has a faster convergence speed in the initial updates. In this paper, we propose a combination of leading and cyclic DCD iterations, the leading-cyclic DCD algorithm, to improve the convergence speed of the cyclic DCD algorithm. The proposed algorithm involves two steps. First, by properly selecting the number of updates of the solution vector used in the leading DCD algorithm, a solution is obtained from the leading DCD algorithm. Second, taking the output of the leading DCD algorithm as the initial values, an improved soft output is generated by the cyclic DCD algorithm with a large number of iterations. Numerical results demonstrate that when the solution sparsity γ is in the interval [ 1 / 8 , 6 / 8 ] , the proposed leading-cyclic DCD algorithm outperforms both the existing cyclic and leading DCD algorithms for all iterations.
Health condition identification for rolling bearing based on hierarchical multiscale symbolic dynamic entropy and least squares support tensor machine–based binary tree

Bearing health condition identification plays a crucial role in guaranteeing maximum productivity and reducing maintenance costs. In this article, a novel tensorial feature extraction approach called hierarchical multiscale symbolic dynamic entropy is developed, which can be used to assess the dynamic characteristic of the measured vibration data at different hierarchical layers and different scales. Besides, the influence of parameters in hierarchical multiscale symbolic dynamic entropy is investigated so as to select the optimal parameters. Then, a new multi-fault classifier called least squares support tensor machine–based binary tree is presented to achieve the fault identification automatically. In the least squares support tensor machine–based binary tree method, the divisibility measure strategy is constructed by two new separability measures (i.e. the average center distance of samples in one class, the center distance of samples between sub-class and global class). Finally, a novel intelligent fault diagnosis scheme based on hierarchical multiscale symbolic dynamic entropy and least squares support tensor machine–based binary tree is developed, which is applied to analyze the experimental data of rolling bearing. The results indicate that the proposed scheme has a superior performance in health condition identification. Compared with the existing symbolic dynamic entropy–based fault diagnosis methods, the proposed method has higher diagnostic accuracy and better stability.
Use of Deep Eutectic Solvents in the Treatment of Agro-Industrial Lignocellulosic Wastes for Bioactive Compounds

Lignocellulose is the most abundant component in nature since it refers to plant material. Beyond the enormous utilization of lignocellulose by human being, unignorable amount of waste is also formed simultaneously. Agro-industrial lignocellulosic wastes can cause environmental pollutions if not processed before discharged. An innovative approach for lowering the detrimental influences of lignocellulosic wastes is to consider them as a source of useful products rather than a waste to be decontaminated. Beyond the conventional techniques for evaluation of the wastes, new emerging techniques and the use of new solvents have drawn attention recently. Among new generation solvents, deep eutectic solvents (DESs) have been increasingly used in the treatment of lignocellulosics to produce value-added products such as biofuels, chemicals, and solvents and also used for the recovery of bioactive phenolic compounds. DESs are used extensively for fractionation of lignocellulosic wastes, often in combination with enzymatic hydrolysis of the biomass. On the other hand, extraction and recovery of bioactive compounds are also under research using DESs. This mini review summarizes the very recent literature reports on the use of DESs in treating agro-industrial wastes within the concept of valorization of biomass.
Constructive Near-Field Interference Effect in a Birdcage MRI Coil with an Artificial Magnetic Shield

Commonly an artificial magnetic shield is used to improve antenna radiation in the far-field region, thanks to the in-phase reflection of electromagnetic waves. Here the authors study the possibility of constructive field interference with respect to the $n\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}a\phantom{\rule{0}{0ex}}r\ensuremath{-}f\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}l\phantom{\rule{0}{0ex}}d$ region. This effect is useful in magnetic resonance imaging, where a conductive scanned sample (such as a patient) is located in the near-field region of radio-frequency coils. The team combines the most popular type of rf coil in magnetic resonance imaging, the ``birdcage'', with an artificial magnetic shield, and demonstrate the near-field efficiency improvement, even at relatively low MRI frequencies.
Two-Tier Converter: A New Structure of High Gain DC-DC Converter with Reduced Voltage Stress

With the advent of distributed generation (DG), the need for efficient power electronic converter is increasing as the incorporation of renewables with battery unit and loads rely heavily on them. This paper suggests an original structure of high-gain DC to DC converter named as “Two-Tier converter” with the reduction in voltage stress. The configuration is resultant of stacking two-stage of the classical boost converter. The voltage gain offered is high for even lower values of duty cycle as the relation of gain is quadratic. Also, the converter current at the input is continuous, and the load configuration offered is grounded. Analysis and operational modes of the proposed converters and effect of the effective series resistance of inductors on voltage gain are presented in detail. A comparative analysis of suggested and new high-gain converters is presented in detail. The suggested configuration is confirmed using detailed simulation studies.
Paludification of boreal soils reduces wood decomposition rates and increases wood-based carbon storage

Over long time periods, paludification reduces aboveground productivity resulting in forest retrogression. Paludified forests are typified by intense accumulation of the soil organic layer and a reduction in soil temperatures and nutrient availability. En route to paludification, early successional forests experience large inputs of deadwood biomass during the senescence of the post-fire cohort, much of which may be entombed in this rapidly growing soil organic layer. Here we examined the effects of paludification across a >2000-year chronosequence of black spruce forests on wood decomposition using three complementary approaches. We (1) repeatedly measured wood density of logs through time, (2) utilize a time-series of logs that varied in time since death, and (3) estimate woody biomass at the stand level as it progresses from live trees to snags, logs and ultimately to buried or decomposed deadwood. Together these approaches demonstrated a 6–7-year delay before the onset of rapid decomposition. We also found strong evidence that paludification results in a large proportion of logs becoming buried in the soil organic layer. Stand level modeling indicates that the rates of accumulation of buried deadwood were greatest following the senescence of the post-fire cohort when both soil organic layer build-up and creation of deadwood peaked. Following this period of high deadwood creation, stands enter a retrogressive state whereby productivity continues to decline albeit more slowly. Continued losses in woody carbon biomass from trees during this retrogressive state are offset by lower wood decomposition rates and a high biomass of accumulated buried deadwood, essentially stabilizing the wood based carbon budget in these ecosystems. We recommend that partial cutting be conducted prior to or near the senescence of the post-fire cohort to improve emulation of natural forest succession in terms of both live tree and deadwood biomass. Furthermore, deadwood during this period has an extremely short residence time and the dynamics of deadwood should recover much quicker than if harvesting is conducted later in succession when there is less live tree biomass and deadwood has longer residence times.
Arachnology in space and time: novel research on arachnid systematics and biogeography

Contemporary molecular and comparative morphological methods have had a huge impact on the understanding of arachnid systematics and biogeography, as they have for many groups of invertebrates. This was clearly evident at the 19th International Congress of Arachnology, which took place in Kenting National Park, Taiwan, from 23 to 28 June, 2013. The Congress was one of the first arachnid meetings to be dominated bymolecular papers in the systematics and biogeography sections, introducing new cases for studying behaviour and biogeography from molecular perspectives, and presenting several studies on species delimitation aided by DNA sequence data. This special issue on Arachnology, which arose from the Congress, is composed of a series of invited papers that pioneer poorly explored arenas of arachnid systematics. These include examples frommultiple arachnid groups, comprising the orders Pseudoscorpiones, Palpigradi, Opiliones and Araneae, as well as a diversity of geographical regions and methodologies. Three papers with an Australian perspective focus on, or make use of, extensive material from Western Australia, dealing with special aspects of phylogeography and cryptic diversity in pseudoscorpions (Harrison et al. 2014) and mygalomorph spiders (Castalanelli et al. 2014), and phylogeny of palpigrades (Giribet et al. 2014). The former two papers highlight the diversity and importance of the Australian biota and provide broad sampling of groups previously thought to contain little diversity. Several other papers also focus on biogeographical aspects at multiple scales, and include studies on Caribbean araneids (McHugh et al. 2014), New Zealand mite harvestmen (Fernández and Giribet 2014) and Mediterranean hexathelid spiders (Opatova andArnedo 2014). The special issue also includes the first phylogenetic hypothesis for the Palpigradi (Giribet et al. 2014), an example using phylogenies to study the evolution of group-living behaviour in kleptoparasitic spiders (Su and Smith 2014), and a paper that focusses on the systematics and taxonomic aspects of the large spider family Pholcidae (Huber et al. 2014). This vibrant collection of papers provides an important contribution to knowledge of arachnids and points to the broad diversity of research being undertaken on systematics, taxonomic groups, questions and approaches in this field. It also adds to the considerable archive of arachnological publications in Invertebrate Systematics, highlighted most recently in a virtual issue on this topic (http://www.publish.csiro.au/view/journals/ dsp_journal_virtual_issues_listed.cfm? VI=Arachnology&nid= 121). We hope that this special issue is of significant interest to both arachnology researchers and invertebrate systematists more generally, and that it serves to stimulate arachnid research even further.
