Sugarcane yield response to calcium silicate on Florida mineral soils

Abstract Silicon (Si) is a beneficial nutrient for sugarcane (Saccharum spp.) and yield responses to Si amendment have been determined on soils with low soluble Si. Because a soil test Si calibration has not been published for sugarcane grown on Florida mineral soils, the objectives were to determine sugarcane yield response to silicon soil amendment on two mineral soils (Entisol and Spodosol) and to relate sucrose yield to soil-extractable Si. Calcium silicate application rates were 0, 3.4, and 6.7 Mg ha−1 (Site 1) and 0, 2.2, 4.5, and 6.7 Mg ha−1 (Site 2) in small-plot (120 m2 plot−1) experiments, with Si application resulting in significant increases in biomass and sucrose ha−1. Calcium silicate requirements of 6.7 and 4.3 Mg ha−1 were determined with initial acetic acid-extractable Si of 21 and 46 g m−3, respectively. Nonlinear models indicated that Si amendments will be required with acetic acid-extractable Si <105 g m−3.
Synergistic effect of Coriandrum sativum L. extracts with cefoxitin against methicillin resistant Staphylococcus aureus, extended-spectrum beta-lactamase producing Escherichia coli and Klebsiella pneumoniae -

Antibiotic resistance has become a general health problem that makes the treatment decisions of clinicians more difficult. Recently, plants and their compounds have been suggested as a potential alternative to antimicrobials.The present study was carried out to evaluate for the first time, possible synergistic interactions on the antibacterial efficacy of Coriandrum sativum L. seed extracts and cefoxitin in combination against three important nosocomial pathogens (methicillin resistant Staphylococcus aureus (MRSA), extended-spectrum beta-lactamase (ESBL) producing Escherichia coli and Klebsiella pneumoniae). The antibacterial effect studied using the disc diffusion and synergism was showed by checkerboard methods. In the disc diffusion method, combinations of both methanol (ME, 1250 µg/mL) and petroleum ether extracts (PE, 1250 µg/mL) with cefoxitin (30 µg/mL) showed an increase in antibacterial activity against all tested microorganisms. It was found that, combinations of Coriander seed ME and PE extracts with cefoxitin have synergistic interactions against ESBL positive K. pneumoniae at 0.03516 and 0.03125 Fractional inhibitory concentration (FIC) index (FICI), respectively. The FICI of combinations against MRSA and E.coli were found to be indifferent by the checkerboard method. An antagonistic effect was not found in these combinations. The current study clearly suggests the potential usage of Coriander seed extracts alone and in combination with cefoxitin for combating infections by ESBL positive K. pneumoniae strains
Egészségműveltséget mérő kérdőívek validálása hazai felnőttmintán Validation of health literacy questionnaires

Bevezetés: Az eredményes gyógyítás, rehabilitáció, egészségre nevelés és egészségfejlesztés elengedhetetlen feltétele, hogy az egyén az egészségműveltségének megfelelő módon jusson hozzá az egészségével kapcsolatos információkhoz. Célkitűzés: A kutatás célja két, az egészségműveltséget objektíven (Newest Vital Sign) és szubjektíven (Brief Health Literacy Screening Tool) mérő skála validálása volt. Ezen nemzetközi felmérésekben elterjedt és önmagukban is alkalmazható rövid tesztek segítségével vizsgálható az általános populáció egészségműveltsége. Módszer: A skálák tesztelése országos keresztmetszeti vizsgálat keretében zajlott a felnőtt lakosság körében. A kérdőívek megbízhatóságát és validitását az egyes kérdőíveken belüli Cronbach-α, Spearman–Brown és korrigált item-totál korrelációs együtthatók, valamint feltáró faktorelemzés (főkomponens-elemzés, varimax rotáció) segítségével értékeltük. Eredmények: A kérdőívek belső konzisztenciáját mérő Cronbach-α-érték a Newest Vital Sign kérdőív esetében 0,72, a Brief Health Literacy Screening Tool kérdőív esetében 0,87, míg a Spearman–Brown-féle korrigált korrelációval számított „split-half” megbízhatóság 0,76, illetve 0,88 volt. Az item-totál korrelációs vizsgálat során kapott korrelációs együtthatók minden esetben magasabbnak bizonyultak az elvárható 0,3-as értéknél. A faktorszerkezet feltárása rávilágított, hogy a két teszt az egészségműveltség más-más dimenzióit méri. Megbeszélés: Eredményeink alapján mindkét teszt megbízhatónak bizonyult; a Brief Health Literacy Screening Tool skála belső validitása magasabb, mint az eredeti kérdőívé. A faktorelemzés alapján a két kérdőív együttes alkalmazása is lehetséges, ha a cél a szubjektív és az objektív műveltség egyszerre történő vizsgálata. Következtetés: Eredményeink alapján javasoljuk a Brief Health Literacy Screening Tool és a Newest Vital Sign kérdőívek általunk validált változatának használatát kérdezőbiztosok által felvett, egészségműveltséget vizsgáló felmérések részeként.

An Optimized SVPWM Strategy for the Postfault Three-Level NPC Voltage Source Inverters

The three-phase three-level neutral-point-clamp inverters can be reconstructed into eight-switch three-phase inverters (ESTPIs) after a single-phase failure. However, different topologies of the ESTPIs are performed according to the failures in different legs, and accordingly, the ESTPIs are controlled by different kinds of space vector pulsewidth modulation (SVPWM) strategies and control algorithms, which may bring concerns in terms of the computational burden. Meanwhile, the dc-link neutral-point voltage fluctuation of the ESTPIs performs the imbalance three-phase current output and significantly deteriorates the fault-tolerant control performance. To address these problems, an optimized SVPWM strategy is proposed in this article. The three SVPWM algorithms are unified by a coordinate transformation, available for any-phase failure. Moreover, the moving average filter with a proportional controller is used to extract the dc component of the neutral-point voltage, which is regarded as the compensated amount to modify the duty-ratio of the basic voltage vectors. Finally, the current imbalance after single-phase failure is suppressed. The effectiveness of the proposed optimized SVPWM strategy is verified through simulation and experimental tests.
Novas formas de performance social no contexto digital da “economia da partilha”

This article investigates how Airbnb and Blablacar use the concept of haring to impact the ways of production of digital capitalism and organize new forms of social dramatization. Through the analysis of the interfaces of these digital platforms, it is argued in the paper that such structures provide to the people using services of sharing economy the organization of an idealized portrait of themselves, that is branded by social imaginaries about collaborative work, mutual trust and communitarian life. It was also found that the functioning of these platforms stimulates the construction of security spaces grounded on procedures of identity validation which are self-regulated through processes of two-sided review and mutual surveillance between both kind of participants. The aim of these processes is to ensure the reliable use of the services between consumers and providers. However, verifying that the success of the "sharing economy" is based on the idea of trust among peers, it was notice that such platforms can be spaces of reaffirmation and reproduction of social inequalities previously felt among social groups historically discriminated.

High-Speed Hybrid-Logic Full Adder Using High-Performance 10-T XOR–XNOR Cell

The main aim of our work is to achieve low power, high speed design goals. The proposed hybrid adder is designed to meet the requirements of high output swing and minimum power. Performance of hybrid FA in terms of delay, power, and driving capability is largely dependent on the performance of XOR-XNOR circuit. In hybrid FAs maximum power is consumed by XOR-XNOR circuit. In this paper 10T XOR-XNOR is proposed, which provide good driving capabilities and full swing output simultaneously without using any external inverter. The performance of the proposed circuit is measured by simulating it in cadence virtuoso environment using 90-nm CMOS technology. This circuit outperforms its counterparts showing power delay product is reduced than that of available XOR-XNOR modules. Four different full adder designs are proposed utilizing 10T XOR-XNOR, sum and carry modules. The proposed FAs provide improvement in terms of PDP than that of other architectures. To evaluate the performance of proposed full adder circuit, we embedded it in a 4-bit and 8-bit cascaded full adder. Among all FAs two of the proposed FAs provide the best performance for a higher number of bits.
A study of the effectiveness of a detergent-based California mastitis test (CMT), using Ethiopian and Nigerian domestic detergents, for the detection of high somatic cell counts in milk and their reliability compared to the commercial UK CMT

Background: The California mastitis test (CMT) is a simple cow-side indicator of the somatic cell count (SCC) in milk, providing a useful tool in identifying cases of subclinical mastitis in cattle. Mastitis, and in particular subclinical mastitis, is a major concern in Ethiopia and Nigeria, yet detection is challenging due to cost and access to commercial CMT reagents. Methods: Commercially available domestic detergents from Ethiopia and Nigeria were compared (n = 3 for each country) with the UK commercial CMT reagent in their ability to detect high SCC (>400,000 cells/ml milk). Sensitivity and specificity of the CMT test were calculated for the different detergents and positive and negative predictive values were established. Results: The average sensitivities of the tests ranged from 28-75% for the Ethiopian detergents and 68-80% for the Nigerian detergents, compared to 76% for the UK domestic detergent. Test specificities were 84-98%, 93-97% and 96%, respectively. Conclusions: Overall, the detergents demonstrated higher specificity than sensitivity. Nigerian detergents performed better than the Ethiopian products, however, the study identified suitable domestic detergents from both Ethiopia and Nigeria, comparable to the UK commercial CMT reagent, and we recommend their use as alternative CMT reagents for livestock-keepers to aid in cost-effective diagnosis of mastitis.
Comparison of computational and experimental saturation vapor pressures of α-pinene + O3 oxidation products

Abstract. Accurate information on gas-to-particle partitioning is needed to model secondary organic aerosol formation. However, determining reliable saturation vapor pressures of atmospherically relevant multifunctional organic compounds is extremely difficult. We estimated saturation vapor pressures of α-pinene ozonolysis derived secondary organic aerosol constituents using FIGAERO-CIMS experiments and COSMO-RS theory. We found a good agreement between experimental and computational saturation vapor pressures for molecules with molar masses around 190 g mol−1 and higher, most within a factor of 3 comparing the average of the experimental vapor pressures and the COSMO-RS estimate of the isomer closest to the experiments. Smaller molecules likely have saturation vapor pressures that are too high to be measured using our experimental setup. The molecules with molar masses below 190 g mol−1 that have several orders of magnitude difference between the computational and experimental saturation vapor pressures observed in our experiments are likely products of thermal decomposition occurring during thermal desorption. For example, dehydration and decarboxylation reactions are able to explain some of the discrepancies between measured and calculated saturation vapor pressures. Based on our estimates, FIGAERO-CIMS can best be used to determine saturation vapor pressures of compounds with low and extremely low volatilities.

Promoting Nursing Students’ Chemistry Success in a Collegiate Active Learning Environment: “If I Have Hope, I Will Try Harder”

The challenge in chemistry courses for nonscience majors (such as nursing majors) is not that the students cannot learn chemistry but that they think they cannot learn chemistry. With this in mind, the authors’ goal was to create a learning environment in which students would feel motivated to learn and would gain confidence in their ability to learn chemistry. In the one-semester chemistry courses for nursing majors described here, health-related scenarios (such as IV therapy, diabetes, blood chemistry, and brachytherapy) provide context, and POGIL activities provide process and content in a cooperative learning environment. In addition, strategic organization and alignment of learning outcomes helps students to focus on the concepts, principles, and theories that they are expected to learn in a meaningful way. Also essential for the success of this course is a caring yet rigorous instructor who effectively communicates that learning chemistry is difficult but doable. This combination of health-related s.
Facile and feasible conductometric immunoanalytical assay for alpha-fetoprotein using platinum-functionalized graphitic carbon nitride nanosheets

A simple and feasible conductometric immunoanalytical method was developed for the sensitive detection of a liver cancer biomarker (alpha-fetoprotein, AFP) on an interdigitated comb-like transducer, using platinum (Pt)-functionalized graphitic carbon nitride (g-C3N4) nanosheets. To construct such an immunosensing platform, platinum nanoparticles were initially loaded on the g-C3N4 nanosheets by the aid of a ethylene glycol reduction method. Thereafter, the as-prepared Pt–g-C3N4 nanohybrids were used as the affinity support for the immobilization of anti-AFP antibodies on the interdigitated electrode. Upon addition of AFP, the analyte reacted with the immobilized antibody to form the antigen–antibody immunocomplex, which was coated on the surface of the modified electrode, thereby partly decreasing the electrocatalytic efficiency of Pt–g-C3N4 towards the reduction of hydrogen peroxide (H2O2) in the presence of iodine ions (I−). The variation in the local conductivity by iodine ions could be detected by using an external conductometer on the basis of the Pt–g-C3N4 electrocatalytic reaction in 10 mM phosphate buffer (pH 6.5) containing 80 μM H2O2, 50 mM KI and 0.1 M NaCl. Under optimum conditions, the immunosensor exhibited good conductometric responses for the detection of AFP within the dynamic linear range of 0.1–100 ng mL−1 at a detection limit of 0.097 ng mL−1. The strong attachment of anti-AFP antibodies to the Pt–g-C3N4 brought good repeatability and intermediate precision down to ±12.7%. Importantly, no significant differences at the 0.05 significance level were encountered for the analysis of 12 human serum samples between the developed immunoassay and human AFP ELISA kit for AFP determination.
Electrostatic Unsteady Thermal Energy Harvester Using Nematic Liquid Crystal

A novel electrostatic unsteady thermal harvester is proposed using nematic liquid crystal as the temperature-sensitive dielectric. With its large anisotropic permittivity and relatively high resistivity, an early prototype is made using fluorinated liquid crystal BCH-5F.F. F. Temperature change of the liquid crystal induces its permittivity change, thereby output voltage is obtained. An effective circuit model is developed and the simulation results are compared with the experimental data for designing harvester with better performance.
