The Monitor project: JW 380 – a 0.26‐, 0.15‐M⊙, pre‐main‐sequence eclipsing binary in the Orion nebula cluster

We report the discovery of a low-mass (0.26 + 0.02, 0.15 + 0.01M O ) pre-main-sequence (PMS) eclipsing binary (EB) with a 5.3 d orbital period. JW 380 was detected as part of a high-cadence time-resolved photometric survey (the Monitor project) using the 2.5-m Isaac Newton Telescope and Wide Field Camera for a survey of a single field in the Orion nebula cluster (ONC) region in V and bands. The star is assigned a 99 per cent membership probability from proper motion measurements, and radial velocity observations indicate a systemic velocity within lσ of that of the ONC. Modelling of the combined light and radial velocity curves of the system gave stellar radii of 1.19 +0.004 -0.18 and 0.90 +0.17 -0.03 R⊙ for the primary and the secondary, with a significant third light contribution which is also visible as a third peak in the cross-correlation functions used to derive radial velocities. The masses and radii appear to be consistent with stellar models for 2-3 Myr age from several authors, within the present observational errors. These observations probe an important region of mass-radius parameter space, where there are currently only a handful of known PMS EB systems with precise measurements available in the literature.
The Effects of Learning Orientation on Implementation of Inbound Open Innovation in Low & Medium-Low Technology Firms

Despite the increasing attention to the open innovation, the effect of strategic capabilities as antecedents to implementation of open innovation in ‘low and medium-low technology’ (LMT) firms in technologically less advanced countries is largely unexplored. This paper strives to fill this gap by investigating the effect of learning orientation on implementation of inbound open innovation. Particularly, effect of commitment to learn, shared vision and open mindedness are considered. Building on the resourced based view, the study theoretically speculates a positive causation from learning orientation to inbound open innovation. Also, the moderating effect of market potential as an external environment component is assessed. Findings from the cross-sectional survey from 272 LMT firms in Sri Lanka reveals that both commitment to learn and open mindedness has positive effect though shared vision has no effect on inbound open innovation. Also, the moderating effect of the market potential is dissimilar. This paper extends the present knowledge by insisting the importance of capabilities particularly, learning capability on implementing open innovation. Findings of this study provide a practical insight into how components of learning capability, and contextual factors influence on implementing inbound open innovation. Finally, this paper points the limitations and further research opportunities.

The Physiological Characteristics, Expression of Oxidosqualene CyclaseGenes and Accumulation of Triterpenoids in White Birch (Betula platyphyllasuk) Saplings by Sa and Meja Treatment

The pentacyclic triterpenoids from birch (Betula platyphylla suk) have broad pharmacological activities and can be potentially used for the development of anti-cancer and anti-AIDS drugs. In this study, we explored the effects of spraying 3-year old white birch with different concentration of methyl jasmonate (MeJA) and salicylic acid (SA) on the expression of key genes in triterpenoid biosynthesis pathways and on the accumulation and physiological characteristics of triterpenoids in birch saplings. The results show that, spraying different concentration of MeJA and SA could obviously promote accumulation of total triterpenoids in 3-year old white birch. The triterpenoid content in the stem bark was significantly increased after 1d of treatment with 1 mmol·L-1 MeJA (MJ2) and after 14 d of treatment with 5 mmol·L-1 SA(SA1), triterpenoid contents of MJ2 and SA1 reaching 81.86 mg/g and 91.40 mg/g, increased by 46.11% and by 45.07% compare control(CK), respectively. In addition, MeJA and SA treatment increased the contents of chlorophyll a and b, antioxidant enzymes superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT), and photosynthetic performance, and affected the content of soluble sugar and soluble protein in birch leaf. Fluorescence quantitative polymerase chain reaction (qPCR) results showed that MeJA and SA treatment deferentially enhanced the expression of key genes farnesyl diphosphate synthase (FPS), cycloartenol synthase (BPX and BPX2), lupeol synthase (BPW) and beta-amyrin synthase (BPY) in triterpenoid synthesis pathway in birch bark and leaves. The results showed that MeJA and SA induced triterpenoid synthesis of birch plant is closely related with not only the expression of key genes of triterpenoid synthesis pathway but also photosynthesis, anti-stress response and physiological indexes, suggesting regulation of triterpenoid synthesis of birch by MeJA and SA may involve in more complex mechanisms at physiological and molecular level.
The application of enzymes for the removal of dyes from textile effluents

Dwindling water resources is a global problem. The effective effluent treatment is an important step towards conserving our water resources. Some pollutants such as dyestuffs resist degradation by conventional treatment methods and persist in the environment. Dye wastes represent one of the most problematic groups of pollutants because they can be easily identified by the human eye and are not easily biodegradable. The use of biotechnological processes in textile dye effluents treatment has attracted considerable attention and achieved interesting results in recent years. This work describes the use of enzymes as an alternative method for the treatment of such pollutants. Noteworthy processes for the treatment of dye waste include a biological treatment, filtration, catalytic oxidation, a sorption process and the combination of treatments. This emphasizes the need for current and future research with the focus on developing economically feasible and environmentally sustainable wastewater treatment practices.
Flavonoid Phenolics in Red Winemaking

This chapter reviews the chemical diversity of flavonoid phenolics in grapes (Vitis vinifera L.) with impact on the sensory properties of red wines. Anthocyanins, flavan-3ols, tannins, and polymeric pigments are discussed from a chemical, technological, and sensory perspective. Anthocyanins, responsible for the color of red wines, reach a peak of extraction after 4 or 5 days of maceration, followed by a decrease in their concentration as maceration progresses. Flavan-3-ols and oligomeric tannins from skins are responsible for bitterness and extracted within the first days of maceration, whereas extraction of seed-derived tannins requires longer maceration times. Matrix effects, including the presence of anthocyanins, polysaccharides, and other cell-wall components affect the rate of retention of tannins into wine. Polymeric pigments, bearing astringent and bitter properties different from those of intact tannins, are formed from covalent reactions between anthocyanins and tannins, putatively accounting for the changes in mouthfeel and textural properties of red wines during maceration and aging. Different maceration techniques applied during red wine production affect the rate, quantity, and the chemical composition of wine phenolics. Understanding of the factors that modulate phenolic retention into wine should allow the winemaker to adjust maceration variables to meet stylistic and/or commercial specifications.
Effect of Seed Heat-Treatment on the Oxidative Stability of Canola Oil Body Emulsions

Enhancement of oxidative stability of canola oil extracted from seed subjected to prior heat-treatment has been attributed to heat-induced generation of antioxidants from phenolic precursors occurring in canola seed. Dispersion of aqueous extracts of intact seed oil bodies (OBs) in water is a novel and interesting way of producing natural and oxidatively stable food emulsions with minimal use of synthetic antioxidants and emulsifiers. As there is growing interest in natural food emulsions containing unsaturated oils, we investigated whether the oxidative stability of canola OB emulsions could be further improved by subjecting canola seed to heat-treatment prior to oil body extraction. Oil-in-water (5%, w/w) emulsions of OBs extracted from canola seed before and after heat-treatment were considerably more resistant to oxidation than emulsions prepared from refined canola oil and Tween? 40 emulsifier. However, only small amounts (0.9% - 4.5% by weight) of the phenolic compounds present in canola seed were transferred to the OBs after aqueous extraction, and consequently there was no discernible effect on oxidative stability as a result of prior heat-treatment of the seed. Thus, in contrast to oil, there is no oxidative stability benefit to be gained by subjecting canola seed to heat-treatment prior to extraction of OBs.
Optical or Inertial? Evaluation of Two Motion Capture Systems for Studies of Dancing to Electronic Dance Music

What type of motion capture system is best suited for studying dancing to electronic dance music? The paper dis-cusses positive and negative sides of using camera-based and sensor-based motion tracking systems for group studies of dancers. This is exempliﬁed through experiments with a Qualisys infrared motion capture system being used alongside a set of small inertial trackers from Axivity and regular video recordings. The conclusion is that it is possible to ﬁne-tune an infrared tracking system to work satisfactory for group studies of complex body motion in a “club-like” environment. For ecological studies in a real club setting, however, inertial tracking is the most scalable and ﬂexible solution.
Factors affecting morbidity and mortality in peptic ulcer perforation

Perforated peptic ulcer is one of the most common surgical emergencies in South India. Peptic ulcers occur due to mucosal damage and subsequent ulceration due to increased aggressive factors, decreased protective factors, or both. The estimated prevalence of peptic ulcer disease in the western population ranges from 5 to 15%, with a lifetime incidence of almost 10%. With the introduction of H2 receptor antagonists and proton pump inhibitors, the incidence of elective surgery for peptic ulcer (PU) disease has decreased dramatically, although complications of peptic ulcer disease such as perforation and bleeding have remained fairly constant. However, there has been a considerable change in the epidemiology of perforated peptic ulcer in the west over the last two decades. Daniel TD mentions that the three most common complications of peptic ulcer disease, in ABSTRACT
Potent insecticidal activity of fruits and leaves of Capsicum frutescens (L.) var. longa (Solanaceae).

Capsicum frutescens (L.) var. longum (Solanaceae) is a well used tropical and subtropical medicinal plant. The present study was undertaken to investigate insecticidal activity of different concentrations of methanol extract of fruits and leaves of C. frutescens against 2nd and 3rd instar larvae of Aedes aegypti. The mortality of the larvae was found to be concentration dependent. Among larvae, 2nd instar larvae were shown to be more sensitive than 3rd instar larvae. The fruit extract has shown more killing effect than leaf extract. Preliminary phytochemical analysis showed the presence of tannins, alkaloids, steroids and glycosides in both extracts. The larvicidal activity of methanol extract may be attributed to the presence of phytoconstituents. This is the first report on the insecticidal potential of C. frutescens. Further studies on isolation of active compounds, mechanism of action, toxicity and field trials are under investigation.
Interactions between fungi, forest management, and ecosystem services

Fungi provide a wide range of ecosystem services (ES) in forests but have for long been difficult to study. Knowledge of their role in soil processes has therefore been lacking and not accounted for in forest management. With the recent development in methodology, we have begun to learn more about fungi and their role in ES provisioning. Interactions between fungi, forest management, and ES were investigated in boreal forests in Sweden. Soil fungal communities were characterised using high-throughput sequencing. Long-term impacts of tree harvesting versus retaining trees on the composition of ectomycorrhizal fungal (EMF) communities were investigated. Furthermore, as part of the Swedish Forest Soil Inventory and National Forest Inventory, and using structural equation modelling, the interplay between soil fungal community composition and tree growth was investigated. Finally, ES provided by fungi in forests were reviewed and potential consequences of Swedish forest management on selected ES were discussed. Temporary retention of trees for ten years did not seem to compensate for harvesting induced changes in EMF communities, which seemingly lasted for several decades. Permanent retention trees enabled local maintenance of some EMF. These results indicate that harvesting induced soil chemistry changes are more important than tree continuity in deciding post-harvest composition of EMF communities. Therefore, if aiming to conserve EMF, it is recommended to retain intact forest patches. Soil fungal community composition seemed to correlate with tree growth. Increased knowledge on fungal functional traits may therefore improve predictions of boreal forest productivity. Intensive management may alter fungal communities leading to undesired consequences for ES provided by fungi. A proposed way to ensure resilience of managed forests is therefore to consider potential impacts of forestry on fungal communities and to simultaneously aim for multiple ES.
Nitrogen Nutrition, Its Regulation and Biotechnological Approaches to Improve Crop Productivity

Nitrogen is the most important macronutrient needed for plant growth and development. The availability of nitrogen in the soil fluctuates greatly in both time and space. Crop plants, except leguminous plants, depend on supply of nitrogen as fertilizers. Large quantities of nitrogen fertilizers are applied to crop plants, but only 33% of it is utilized by the plant. Plants have developed efficient mechanisms to sense the varying levels of nitrogen forms and uptake them. They also have well developed mechanisms to assimilate the incoming nitrogen immediately or translocate to different parts of the plant wherever it is needed. Maintenance of nitrogen homeostasis is essential to avoid toxicity. Apart from translocation and assimilation, plants have developed different mechanisms, nitrogen efflux; vacuolar nitrogen storage and downward transport of nitrogen from aerial parts to roots, for maintaining nitrogen homeostasis. In crop plants the “grain yield per unit of available nitrogen in the soil” is referred as the nitrogen use efficiency (NUE) for which remobilization of nitrogen, mediated by various transporters plays a crucial role. All these processes are tightly regulated by proteins and microRNA in response to both external and internal nitrogen levels, carbon status of the plant and hormones. As most crop plants are non-leguminous and depend on soil nitrogen, more production could be achieved if crop plants can be made to utilize the available nitrogen efficiently. The recent explosion of research information and the mechanisms behind nitrogen sensing, signaling, transport and utilization enables biotechnological interventions for better nitrogen nutrition of crop plants. This review discusses such possibilities in the context of recent understanding of nitrogen nutrition and the genomic revolution sweeping the crop science.
Application of the method of additional conditions to the Neumann problem for the Laplace equation in the wedge

The method of additional conditions (MAC) gives a well characteristic of the finite stresses near the tip of a crack of the Griffth's problem in fracture mechanics, where is supposed of a finite elastic potential which entails the zero value of the integral. MAC uses special additional conditions to correct the given traditional problems. It could be considered as a method introducing a special variation to smooth the contradiction between the given problem and introduced additional condition. In this paper we apply this method to the probably most frequently occurring partial differential equation governing the behavior of certain physical quantities. The Laplace equation is considered in the wedge. For the given Neumann problem the derivative of the solution has a singularity at the origin for an obtuse angle. The solution is unique. The singularity can be considered as impossible from the physical point of view. There is suggested an additional condition which follows from the classical Green's formula and from the supposed to be bounded solution and its derivatives, and that can characterize the nonsingular solution at the origin. The first approximation is considered.
Landscape restoration after oil sands mining: conceptual design and hydrological modelling for fen reconstruction

Extraction of oil sands in the relatively dry Western Boreal Plains near Fort McMurray, Alberta, destroys the natural surface cover including fen peatlands that cover upto 65% of the landscape. Industry and environmental monitoring agencies have questioned the ability to reclaim fen peatlands in the post-mine landscape. This study proposes a conceptual model to replace fen systems with fen peat materials supported by groundwater inflow from a constructed watershed. A numerical model is used to determine the optimum system geometry, including the ratio of upland to fen area, thickness and slope of sand materials, and thickness of peat and of the liner that would result in flows that sustain peat wetness to a critical threshold soil water pressure of −100 cm of water at a peat depth of 10 cm. We also test the sensitivity of the system to variations in the value and spatial configuration of the hydraulic conductivity (K) of locally available materials. The optimal conditions were achieved using an upland area at least twice that of the fen, underlain by a sloping (3%) layer of fine-grained material with hydraulic conductivity (K) of 10−10 m/s, that maintains lateral groundwater flow in a sand layer with K of 10−4 to 10−5 m/s. Using daily climate inputs that included 1998, the driest summer on record, the model suggests that adequate wetness can be sustained in the fen for the growing season, and that the extent of water table recession was similar to undisturbed systems during that period.

Almost all its parts such as leaves, bark, root, flower, pods, gum, etc. are used in medication. This article briefly reviews the ethanobotanical as well as medicinal uses of A. nilotica with plant description.
On the Conditional Effect of Fine Particulate Matter on Cancer Mortality: Case Study of OECD Countries

Given the adverse effects of air pollution on human health, a lot of studies have empirically investigated the causal effect of air pollution on health. However, no study has considered how fine particulate matter interacts with GDP per capita to affect cancer mortality. This study therefore uses data for 20 OECD countries to estimate the conditional effect of air pollution on cancer mortality. To this end, a fixed effect panel regression model which takes both country and time fixed effects into consideration is estimated. The conditional causal effect of fine particulate matter was found to be negative 0.22 and significant at 1% level.
Interactions between ants, fruits and seeds in a restinga forest in south-eastern Brazil

Fleshy diaspores (fruits, seeds) comprise a large portion of the litter on the floor of tropical forests, and interactions involving litter-foraging ants and diaspores are common in these areas. In this study, the interactions between ants and non-myrmecochorous diaspores (i.e. not adapted to dispersal by ants) were surveyed along a 1.4-km transect in a restinga forest (sandy soil) on the coast of south-eastern Brazil. During 2 y of monthly samplings, 562 interactions involving 48 ant species and 44 species of diaspore (0.02–11.10 g) were recorded. Ant–diaspore associations involved a considerable part of the ground-dwelling ant community. Large ponerine ants individually removed the diaspores up to 13 m, whereas small ants (myrmicines) normally recruited workers and consumed the diaspore on the spot. Ant-derived benefits to diaspores of non-myrmecochorous plants included secondary dispersal (small to medium-sized diaspores), and increased germination success after seed cleaning by ants. Large ponerine ants such as Odontomachus chelifer and Pachycondyla striata were the main seed vectors. Seedlings of three species were associated with nests of O. chelifer. The results indicate that ants play an important role in fruit/seed biology in the restinga forest.
