Efecto de insecticidas sobre Liriomyza sativae (Diptera: Agromyzidae) y sus parasitoides en frijol, Phaseolus vulgaris

Liriomyza sativae una especie minadora de hojas notoriamente polifaga, constituye una de las principales causas de aplicaciones de insecticidas en frijol, Phaseolus vulgaris en Ecuador. No obstante, asociadas a este insecto existen varias especies de parasitoides las cuales generalmente regulan sus poblaciones cuando no existe interferencia debido a las aplicaciones de insecticidas. Para evaluar la magnitud del control biologico natural por estos parasitoides se realizaron dos estudios en el Centro Experimental “El Misionero” Guayas, Ecuador. En uno se observo la fluctuacion poblacional de L. sativae y la incidencia de sus parasitoides en una parcela sin insecticidas. En el otro se evaluaron los mismos factores en un experimento comparando dos tratamientos: 1. sin aplicaciones de insecticidas y 2. con aplicaciones semanales de una formulacion comercial de lambda cihalotrina + tiametoxam. En ambos casos se observo la diversidad de los parasitoides asociados con este minador. En el primer estudio se detecto baja infestacion (1,8 minas. foliolo -1) y alto porcentaje de parasitismo en minas (70,5 %). En el experimento los promedios generales de minas con larvas activas y porcentajes de parasitismo resultaron 11,8 ± 2,9 y 23,3 ± 5,0 % vs. 3,1 ± 0,8 y 61,8 ± 7,7 % para plantas tratadas con insecticidas y no tratadas, respectivamente. Closterocerus sp. , Chrysocharis sp. y Neochrysocharis sp. (Hymenoptera: Eulophidae) fueron los parasitoides de larva encontrados, asi como Ganaspidium sp. (Hymenoptera: Figitidae), un parasitoide de larva-pupario. Los resultados muestran la importancia de los parasitoides como reguladores de poblaciones de L. sativae y la interferencia de las aplicaciones indiscriminadas de insecticidas con el control biologico natural.
Real Drive Well-to-Wheel Energy Analysis of Conventional and Electrified Car Powertrains

Reducing fuel consumption and global emissions in the automotive sector has been a main focus of vehicle technology development for long time. The most effective goal to achieve the overall sustainability objectives is to reduce the need for non-renewable and fossil resources. Five vehicles, two conventional ICE, two hybrid-electric, and one pure electric powertrain, are considered. Non-renewable primary energy consumption and CO2 emissions are calculated for each powertrain considered. All data—including calculated values—are based on the experimental measure of fuel consumption taken in real driving conditions. The data were recorded in an experimental campaign in Rome, Italy on urban, extra-urban streets, and highway on a total of 5400 km and 197 h of road acquisitions. The analysis shows significant reductions in non-renewable fossil fuel consumption and CO2 emissions of hybrid-electric powertrains compared to conventional ones (petrol and diesel engines). Furthermore, a supplementary and very interesting comparison analysis was made between the values of energy consumptions measured during the tests in real driving conditions and the values deriving from the NEDC and WLTP homologation cycles.

Speciation and infrageneric classification in the planktonic dinoflagellate Tripos (Gonyaulacales, Dinophyceae)

The genus Tripos , formerly marine species of Ceratium , is the dinoflagellate with the greatest number of species and infraspecific taxa (~800) due to the high morphological intraspecific variability of numerous species. In the past, the species of Tripos were proposed into distinct genera. A re-instatement of this generic split is not justified due the difficulties to circumscribe the basal subgenera Amphiceratium and Archaeceratium , and the polyphyletic character of Biceratium . A new infrageneric classification is proposed. The subgenus Amphiceratium is dismembered after the classification of the sections Inflata and partially Fusiformia into Archaeceratium . The subgenus Tripos (autonym) replaces other names such as Tripoceratium or Orthoceratium . Based on the original descriptions, the records of T. furca and T. lineatus correspond to T. eugrammus and T. furca , respectively, and T. macroceros has been reported as T. contrarius . The names T. belone and T. carriensis have been misapplied for T. pacificus and T. volans , respectively. Tripos arcuatus , T. gracilis , T. inclinatus , T. scapiformis and T. subcontortus are revived to replace T. euarcuatus , T. declinatus , T. horridus , T. longirostrum and T. contortus , respectively. The species T. ramakrishnae and T. fusus var. schuettii were described from individuals infected by endoparasites. Tripos rotundatus comb. nov . is proposed for C. digitatum var. rotundatum. As a result of taxonomic revision, Tripos is restricted to 57 correct species, although the speciation and synonymy is largely incomplete due to lack of studies in the life cycle and molecular data.
A novel wearable wideband antenna for application in wireless medical communication systems with jeans substrate

Abstract In this paper, a novel wearable wideband antenna for application in wireless medical communication systems (0.9–6 GHz) is designed. For bandwidth enhancement, five parallel metal plates (PMPs) are placed on the top of the antenna’s patch without any disturbing effects on the performances. With the help of the proposed method, the bandwidth has been increased by about 3 GHz in comparison with the conventional one. The antenna dimensions are 60 × 48 × 0.8 mm3 or 0.72 × 0.57 × 0.009 λg 3 where λg is the guided wavelength at 2.4 GHz. Simple design, wearable, wide bandwidth, and compact size are the most important benefits of the proposed antenna. Finally, to prove the simulations and designs, the proposed antenna was fabricated. The measurement outcomes are also consistent with the simulation results.
Genomics and Computational Techniques Facilitate Understanding Antimalarial Drug Mechanisms of Action and Mechanisms of Resistance

by Katrina A. Button-Simons Malaria mortality has decreased substantially since 2000, largely due to the success of artemisinin combination therapies (ACTs). However, these gains are threatened by the emergence of artemisinin resistance in Southeast Asia. If artemisinin resistance spreads from Southeast Asia to Africa, as has happened for other drugs, malaria deaths due to Plasmodium falciparum would increase dramatically. There is an urgent need to develop new classes of effective antimalarial drugs and to extend the effectiveness of ACTs. Historically, ACTs contain partner drugs with a long metabolic half-life to counteract the rapid metabolism of artemisinin. Ideally, partner drugs in combination therapies should act synergistically, targeting different pathways. This requires knowledge of drug mechanism of action (MoA) and mechanism of resistance (MoR), which may not be related to MoA. Unfortunately, MoA and MoR are difficult to determine for large numbers of drugs using standard methods. Understanding MoA and Katrina A. Button-Simons MoR for artemisinin and candidate drugs will enhance our ability to rationally identify optimal ACT partner drugs to overcome existing resistance and to buy time to allow new drugs to progress through the drug development pipeline. Transcription profiling and chemogenomic profiling are ideal for quickly evaluating MoA of many compounds. Chemogenomic profiling is a powerful tool for determining drug MoA by comparing profiles of susceptibilities to a panel of drugs in a collection of mutant lines representing a wide range of disrupted genes. In our studies, artemisinin functional activity was linked to signal transduction and cell cycle regulation pathways. Transcription profiling of Plasmodium parasites perturbed briefly with sublethal concentrations of drug can be used to generate a drug pathway fingerprint to infer MoA. Transcriptional signatures of artemisinin resistance can be used to predict novel partner drugs for ACTs to treat artemisinin resistant infections. Artemisinin MoR is not fully understood. Pathway-based networks analysis of genomic variation data and gene expression data from published studies of artemisinin resistance can provide a more complete understanding of the mechanism underlying artemisinin resistance. Understanding MoA for drug candidates, along with a thorough understanding of artemisinin MoR would enhance efforts to design new combination therapies that can circumvent artemisinin resistance.
Assessing the sustainability of subsistence fisheries of small indigenous fish species: fishing mortality and exploitation of hill stream loaches in India

Small, least conspicuous fish species are targeted through subsistence fisheries in many regions of the world, but little is known about their population dynamics or exploitation levels. In the Western Ghats of India, part of a global biodiversity hotspot and an exceptional region of freshwater fish diversity and endemism, several small species of loaches are caught and sold in the local markets by marginalized communities through an unmanaged fishery, resulting in high levels of exploitation. Of particular concern is the fishery for the spiny loach, Lepidocephalichthys thermalis whose exploitation rates at various sites in the northern part of the Western Ghats region were observed to be greater than their E 50 (exploitation rate where the stock is reduced to half its virgin biomass). A comparison of various fishing sites showed that populations in the high anthropogenic impact areas (located close to urban settlements with high human population density, and impacted by various threats, i.e. introduced species, pollution) are exploited at a rate greater than 86% of their E max (exploitation producing maximum yield). The first quantitative information on population dynamics and exploitation levels of small indigenous fish species in tropical rivers indicates their potential vulnerability to over fishing, and is an important starting point for further investigations into similar fisheries in other regions of Asia and Africa.
Examining the importance of gamification, social interaction and perceived enjoyment among young female online buyers in India

Purpose The current research has dual motives. Firstly, this study aims to evaluate the effect of gamification on the behavioural intention (BI) of the young female consumers to use online websites for making purchases. Secondly, it examines the role of social interaction and perceived enjoyment (PE) – two antecedents that are considered to have an impact on the female buying behaviour in e-commerce. Design/methodology/approach A model is developed based on the technology acceptance model. The conceptual framework is augmented with additional constructs such as gamification, PE and social interaction. Data from a survey of 898 female respondents from India was collected to assess the proposed framework. The study uses partial least squares structural equation modelling technique to empirically validate the model. Findings Gamification exhibits a favourable influence on BI of young female consumers. Gamification also has a favourable and an indirect influence on BI through social interaction and PE. Although, gamification has a significant influence on perceived usefulness, the latter has no impact on the BI. The BI of using an online shopping website is directly associated with the buying intention. The online retailers need to offer an enjoyable and interactive experience to the female consumers so that the influence of gamification is sustainable. Originality/value The current research enlarges the ambit of gamification in the e-commerce segment, an area where empirical research is sparse. It highlights the significance of social interaction and PE as mediators. To the best of the author’s knowledge, gamification’s influence on female online buying behaviour has never been analysed before and hence different segmentation and marketing strategies are required to cater to their unique needs.

First Report of Heterobasidion occidentale on Sequoia sempervirens in Northern California

In 2007, Heterobasidion basidiocarps (“fruit bodies”) were found on 37 of 200 coast redwood (Sequoia sempervirens) stumps surveyed in four stands owned by the Green Diamond Resource Company near McKinleyville, CA (Humboldt County). All were second or third growth stands, last logged 7-13 years prior to the survey here described. In 2015, during a second follow-up survey, 10 fruit bodies and two rotted wood samples were collected from 10 separate stumps, their DNA was extracted, and the Internal Transcribed Spacer was amplified and sequenced using the ITS1f-ITS4b primers described by Gardes and Bruns (1993). All sequences (e.g. GenBank Accession No. MF488718) had a 99-100% homology with ITS sequences of Heterobasidion occidentale (e.g. Accession No. KC492946), a widespread root and butt rot agent common on Abies, Picea, and Tsuga spp. in western North America, and also found on Sequoiadendron giganteum in the Central Sierra Nevada (Garbelotto and Gonthier 2013). Sapwood in 97% (range 96-100%) of the 200 st.
Modular Approach to Adipose Tissue Engineering

Despite the increasing clinical demand in reconstructive, cosmetic and correctional surgery there remains no optimal strategy for the regeneration or replacement of adipose tissue. Previous approaches to adipose tissue engineering have failed to create an adipose tissue depot that maintains implant volume in vivo long-term (>3 months). This is due to inadequate mechanical properties of the biomaterial and insufficient vascularization upon implantation. Modular tissue engineering is a means to produce large volume functional tissues from small sub-mm sized tissues with an intrinsic vascularization. We first explored the potential of a semi-synthetic collagen/poloxamine hydrogel with improved mechanical properties to be used as the module biomaterial. We found this biomaterial to not be suitable for adipose tissue engineering because it did not support embedded adipose-derived stem cell (ASC) viability, differentiation and human microvascular endothelial cell (HMEC) attachment. ASC-embedded collagen gel modules coated with HMEC were then implanted subcutaneously in SCID mice to study its revascularization potential. ASC cotransplantation was shown to drive HMEC vascularization in vivo: HMEC were seen to detach from the surface of the modules to form vessels containing erythrocytes as early as day 3; vessels decreased in number but increased in size over 14 days; and persisted for up to 3 months. Early vascularization promoted fat development. Only in the case of ASC-HMEC cotransplantation was progressive fat accumulation observed in the module implants. Although implant volume was not maintained, likely due rapid collagen degradation, the key result here is that ASC-HMEC cotransplantation in the modular approach was successful

Temperature Control Project that Facilitates Learning of Difficult Concepts in Control Theory

This paper presents a design project and its assessment in an undergraduate control theory course. In the project, students mathematically modeled the thermal dynamics of a glass incubator and its heat source. Based on these models, they designed a lag compensator to keep the incubator temperature in a safe range when the external temperature fluctuates. It is hypothesized that activities planned in this real-world project can facilitate the learning of difficult controller design via the frequency response method. Multiple facets of student learning were assessed, including (a) a two-level objective assessment based on students’ written reports and (b) four-category student self-evaluation surveys. The former identifies how the project helps achieve ABET outcomes and how each of the four project activities support learning outcomes. Surveys assess students’ factorial knowledge and their perception about the project. Assessment results demonstrate that this project-based-learning experience effectively aids students in grasping difficult frequency-domain concepts and design methods.
Carbonylative Suzuki–Miyaura Coupling Reactions of Aryl Iodides with Readily Available Polymer-Immobilized Palladium Nanoparticles

Abstract Polysilane/alumina-supported palladium nanoparticle catalyzed carbonylative Suzuki–Miyaura coupling reactions under ligand-free conditions have been developed to synthesize diaryl ketones. High yields and selectivities were achieved even with low catalyst loading under atmospheric pressure of CO gas. A variety of aryl iodides and arylboronic acids could be utilized to afford the diaryl ketones in excellent yields. Moreover, the ligand-free immobilized palladium nanoparticles could be recovered by simple filtration and the catalytic activity could be maintained for several runs.

Only Daucosterol (5) has exhibited antiradical activity with an IC50 of (13.005 ± 0.005) mg/mL among the isolated compounds. Conclusion: This study provides scientific evidence and support for the traditional uses of F. abutilifolia stem barks in the treatment of diseases associated with oxidative stress.
Assessment of parasitic fungi for reducing soybean cyst nematode with suppressive soil in soybean fields of northeast China

ABSTRACT Experiments were conducted to study the inhibitor factors present in suppressive soil that suppressed the soybean cyst nematode (SCN) in the black soil fields with 21 years continuous cropping of soybean (SSSS) and 3 years continuous cropping of soybean followed by 1 year corn (SSSC). Compared with the SSSC field, the densities of SCN significantly (P < 0.05) declined in SSSS field. In a soil microcosm with suppressive soil, the population of SCN decreased after the addition of pimaricin (fungal inhibitor) and streptomycin (bacterial inhibitor), but the population of SCN declined more significantly by adding streptomycin to the suppressive soil than adding pimaricin. Fusarium equiseti, Pochonia chlamydosporia and Purpureocillium lilacinum were isolated from cysts, eggs and J2 of SCN and soil in SSSS and SSC field. The population density of these parasitic fungi was significantly (P < 0.05) higher in SSSS field than in SSSC field. The density of P. chlamydosporia was higher than other fungi. Real-time PCR was used to test genomic DNA of P. chlamydosporia in SSSS and SSC field soil. The mass of genomic DNA and the population density of P. chlamydosporia were significantly (P < 0.05) higher in SSSS field than in SSSC field. This study has revealed that fungi, especially P. chlamydosporia, may play an important role in the suppression of SCN population in the suppressive soil.
