EFFECTS OF VARIABLE THERMAL CONDUCTIVITY AND CHEMICAL REACTION ON STEADY MIXED CONVECTION BOUNDARY LAYER FLOW WITH HEAT AND MASS TRANSFER INSIDE A CONE DUE TO A POINT SINK

The steady incompressible mixed convection boundary layer flow with variable fluid properties and mass transfer inside a cone due to a point sink at the vertex of the cone have been investigated. The fluid viscosity and thermal conductivity have been assumed to be temperature dependent. The governing fluid flow equations with boundary conditions have been transformed into set of coupled ordinary differential equations with the help of similarity transformations and solved Runge-Kutta method with shooting technique. The effects of Schmidt number, variable thermal conductivity parameter, mixed convection parameter, buoyancy parameter and chemical reaction parameter on velocity distribution, temperature distribution, concentration distribution, heat transfer rate and coefficient of skinfriction have been investigated. It is observed that concentration decreases with increasing Schmidt number and temperature increases with increasing values of thermal conductivity parameter. Also with increasing values of mixed convection parameter, velocity, temperature and concentration decreases. The present study is relevant in conical nozzle and diffuser flow problems exist in petroleum and chemical industries.
Effects of High Auxin Concentrations, Cold Storage, and Cane Position on Improved Rooting of Vitis aestivalis Michx. Norton Cuttings

More than 3,000 Norton hardwood cuttings were tested in an experiment conducted under commercial greenhouse propagation conditions. Treatment with 10,000 or 15,000 mg/L potassium salt of indolebutyric acid (KIBA) caused >70% of the cuttings to root, compared with 23% rooting of the nontreated control cuttings. In studies at a university greenhouse under intermittent mist, cuttings that were collected in January and stored in a cooler at 5°C for ≥55 days (>2300 hours of natural plus cooler chilling) formed more roots than cuttings receiving fewer hours of chilling. Cuttings in this experiment that were treated with 15,000 mg/L KIBA formed significantly more roots than cuttings not treated with auxin. Hardwood cuttings and softwood cuttings taken from more basal or middle cane segments rooted better than cuttings from nearer the apical region. Softwood cuttings formed more roots when treated with 2,500 mg/L KIBA compared to the nontreated control cuttings.
Bibliometric analysis of Scopus indexed publications on polymyxin resistance (2009-2018)

Background: Antimicrobial resistance is a serious public health problem that has become a global threat. Special attention should be given to polymyxins (polymyxin B and colistin) which, since their reintroduction into clinical practice, are considered "last resort" drugs. The objective of this study is to perform a bibliometric analysis of scientific research on polymyxin resistance.Methods: Scopus database was used to retrieve documents relevant to polymyxin resistance. At the beginning, all kinds of documents without year restrictions were included. Subsequently, the study period (2009-2018) was limited and analyzed using SciVal. Specifically, the 10 institutions and countries with the highest production, authors, journals, and most cited articles were analyzed. The growth of publications and citations was graphed, in addition to an analysis of the keywords using VOSviewer.Results: A total of 1,306 documents were retrieved (1947-2019). Original articles (76.95%) and letters to the editor (15.47%) were the most frequent types of documents. English was the predominant language with 1,270 documents (97.2%). In the period 2009-2018, there was a significant growth in publications (p-value < 0.001) retrieving 833 (64%) documents. The received citations were 23,974, with a peak in 2016 (8,033 citations). The United States and China lead the scientific production with 146 (17.5%) and 137 (16.4%) publications, respectively. University of Fribourg (Switzerland) was the most productive institution on the subject (44 documents), although University of Zhejiang (China) has caused the greatest impact (73.5 citations/article). Antimicrobial Agents and Chemotherapy ranked first with 140 documents. Most of the documents were published in quartile 1 journals (82.7% and 69.1%, according to Scimago Journal & Country Rank and CiteScore, respectively). Conclusions: The number of documents on polymyxin resistance has increased significantly in the recent years. In the last few years alone, 64% of all documents have been published. The United States and China lead the scientific production. Greater efforts are still needed to tackle this global problem.
Theoretical study of protonic conduction in Gd-doped BaCeO3 : an electrolyte for fuel cell

This thesis deals with the study of protonic diffusion, and to a lesser extent ionic, inside a Gd-doped BaCeO3, a possible electrolyte for fuel cell, using a multi-scale approach. First of all, first principles calculations have been made to determine stable positions for protonic defects OH_O and oxygen vacancies V O in the material. Then, using the same formalism of density functional theory, energy barriers for both kinds of defects have been computed between two stable positions. Finally, these barrier heights have been used in a Kinetic Monte-Carlo algorithm to simulate trajectories of protons or oxygen vacancies. This method allows to access macroscopic values that can be found by experiments, such as activation energy, diffusion coefficient or mobility, using only atomic data coming from ab initio simulations. Gadolinium seems to be an interesting dopant in barium cerate considering its weak power of attraction on the proton: the introduction of gadolinium creates lots of oxygen vacancies that will be able to incorporate water molecules, without trapping the hydrogen. Both these conditions are necessary to get a good electrolyte for protonic ceramic fuel cell.
Neogene restoration of geometry of the Neotethyan suture zone in Central Anatolia (Turkey)

ABSTRACT We have restored the geometries of suture zones that involved various continental blocks in central Anatolia during the Neogene, using palaeomagnetic data. Previously, the Kırşehir Block was proposed to be an NNE-SSW striking tectonic block broken into three fragments that they underwent clockwise rotations in the north and counter-clockwise rotations in the south during the Palaeogene, due to collision and N-S shortening of the Kırşehir Block between Tauride-Menderes Block in the south and the Pontides in the north. Our new results point out five distinct Neogene tectonic domains with distinct rotation patterns that indicate the rotational deformation of Central Anatolia is far more complex than generally presumed. Among these, 1) Kırıkkale-Bala Domain is rotated ~18° clockwise, 2) the Tuz Gölü Domain underwent ~14° counter-clockwise rotation, 3) the Alcı-Orhaniye Domain rotated ~35° counter-clockwise sense, 4) the Northern Haymana Domain underwent ~12° counter-clockwise rotation while 5) the Southern Haymana Domain underwent very small (~5° clockwise) net rotation since the early Miocene. The results also indicated that pre-Neogene configuration of the Izmir-Ankara Suture Zone was striking almost E-W while Inner-Tauride and Ankara-Erzincan suture zones were almost N-S in the study area. In addition, the fault zones that define the these domains extend from the Kırşehir Block into the over-riding blocks (Pontides) continuously without any deflection indicating that they were active during the Neogene and fragmented and dislocated the suture zones in the region.
Thiophene Donor for NIR-II Fluorescence Imaging Guided Photothermal/Photodynamic/Chemo Combination Therapy

Organic fluorophores/photosensitizers have been widely used in biological imaging and photodynamic and photothermal combination therapy in the first near-infrared windows. However, their applications in the second near-infrared (NIR-II) windows are still limited primarily owing to low fluorescence quantum yields (QYs). Here, a boron dipyrromethene (BDP) as the molecularly engineered thiophene donor unit with high QYs to the redshift is created. Thiophene insertion initiates substantial redshifts of the absorbance, as compared to its counterparts that introduce iodine. The fluorescent molecule can be triggered by a NIR laser with a single wavelength, producing emission in the NIR-II windows. Single NIR laser triggered phototherapeutic nanoparticles (NPs) are developed by encapsulating the BDP and chemotherapy drug docetaxel (DTX) using a synthetical amphiphilic poly(styrene- co -chloromethyl styrene)-graft-poly(ethylene glycol) functionalized with folic acid (FA). These BDP-T-N-DTX-FA NPs not only show superior solubility and high singlet oxygen quantum yield (ΦΔ =62%), but also demonstrate a single NIR laser-triggered multifunctional characteristics. After intravenous injection of the NPs into 4T1 tumor-bearing mice, the accumulation of the NPs in the tumor presented a high signal-to-background ratio (11.8). Furthermore, the 4T1 tumors in mice were almost eradicated by released DTX and PDT/PTT combination therapy from the BDP-T-N-DTX-FA NPs under the single NIR laser excitation.
Coping with the new norm: ICT-pedagogy integration awareness and competencies of TEI faculty

This study examined the Information and Communications Technology (ICT) - pedagogy integration awareness and competencies of faculty members of a teacher education institution (TEI). Descriptive research method was employed through the use of survey questionnaire to collect data. Fifty (50) faculty members served as respondents in this study. Most of the respondents perceived themselves to be extremely aware of utilizing ICT tools/ equipment and moderately aware of using application software despite reporting that they were self-taught in acquiring basic ICT skills. They were also found to be proficient in terms of level of competency in integration. It was also discovered that most areas of their competency were significantly related to respondents’ awareness in using ICT. This paper suggests that higher education institutions should devise innovative teacher training programs that will increase the ICT pedagogy awareness and integration of teacher education faculty members.

A new Schiff base NaL was prepared by condensation of sodium (3E)-3-hydrazinylidene-3H-1,2benzoxazole-2-ide-1,1-dioxide with 7-methyl-3-oxo-3,4-dihydroquinoxaline-2-carbaldhyde. The transition metal complexes of Cobalt (II), Nickel (II), Copper (II), Zinc (II) and Cadmium(II) with [L] Schiff base were prepared and fully Characterization on the basis of elemental analysis, HMR, Mass spectroscopy, FTIR and electronic spectra, as well as the molar conductivity and magnetic moment measurements were carried out to adopt the Octahedral geometry of [ML X.2H2O], M= Co(II),Ni(II), Cu(II), X=NO3 whereas the geometry of Zn(II) and Cd(II)complexes[MLX], X= Cl show tetrahedral geometry. The antimicrobial activity of the free Schiff base NaL and its metal complexes were screened against two gram positive and two gram negative bacterial Escherichia coli and Staphylococcus aures. It is obtained that the zinc (II) and Cd(II) complexes exhibited the highest inhibition zone in compared with the free ligand.
A Comparative Study of International and Chinese Public Health Emergency Management from the Perspective of Mapping Knowledge Domains

Background: At the end of 2019, the outbreak of the coronavirus disease 2019 (COVID-19) had severely damaging people’s life. China’s public health emergency management system had played an essential role in the handling and response of it, which had been appreciated by the World Health Organization and some countries. Hence it is necessary to make an overall analysis of the development of China’s health emergency management system. It can provide a reference for scholars to understand the current situation and look for new research points. Methods: We collected 2247 international from the Web of Science database, 959 Chinese articles from China National Knowledge Infrastructure database. Bibliometric and mapping knowledge domains analysis methods were used in this study for temporal distribution analysis, cooperation network, co-word network analysis. Results: The first international article in this field was published in 1991, while Chinese in 2005. Research institutions mainly come from universities and health institutions. Developed countries and European countries published more articles, while east of China published more. There are 52 burst words for international articles from 1999–2018, while 18 burst words for Chinese articles from 2003–2018. International top-ranked articles by citation appeared in 2005, 2007, 2009, 2014, 2015, 2016, while Chinese appeared in 2003, 2004, 2009, 2011.Conclusions: There are differences in the regional or economic distribution of international and Chinese cooperation networks. International research often relates to hot issues, mainly focus on the emergency preparedness and monitoring for public health events, while China’s focus on the public health emergency and their disposal. International begins the research with terrorism and bioterrorism, followed by disaster planning and emergency preparedness, epidemics and infectious diseases. China takes severe acute respiratory syndrome as the research background and legal system construction as the research starting point, followed by mechanism, structure, system, and learning from abroad of public health emergency management.
Influence of Crop Residue Types on Microwave-Assisted Liquefaction Performance and Products

Microwave-assisted polyhydric liquefaction of crop residues was a useful method for the conversion of lignocelluloses into biopolyols. Five types of crop residues were selected to investigate the effect of feedstock varieties on the microwave-assisted liquefaction performance and products. The microwave-assisted liquefaction characteristic of different feedstocks in ethylene glycol (EG) was evaluated by residue component analysis and kinetics modeling. Cellulose was proven to be the main residual content, and hemicelluloses and lignin were liquefied rapidly. According to the first-order model, degradation of cellulose was indicated to be the rate-determining step in the microwave solvolysis liquefaction of crop residues. Among the five types of crop residues, rice straw was the material most difficult to be liquefied. Acid-insoluble ash (AIA) was found to be significantly negatively correlated with the liquefaction rate of crop residues and cellulose. The hydroxyl number and acid number of microwave-assis.
Effect of DTPA and hydrogen peroxide on activated sludge performance

This work explores the behaviour of a standard biological treatment system when exposed to two of the most common residuals from novel bleaching processes: hydrogen peroxide and the chelant DTPA. The potential problems for an activated sludge biological treatment unit, from the introduction of a chelating agent and hydrogen peroxide, were anticipated to stem from the sequestering of vital trace elements by the chelant, and the oxidation of biomass by the hydrogen peroxide. Typical residual quantities from TCF bleaching processes are 0.875 g DTPA / L and 0.2 g FL,02 / L, although the peroxide residual concentration is variable, up to approximately 1 g/L. The effects of running a typical biological treatment system on effluent from novel bleaching processes were also determined, in addition to the effects of switching influent sources between novel and conventional bleaching effluent. Activated sludge secondary treatment systems could successfully treat elementally chlorine free (ECF) and totally chlorine free (TCF) bleached kraft mill effluents by achieving > 90% BOD removal, > 40 % COD removal, and 100% acute toxicity removal. Influent feed changes between untreated chlorine free bleaching effluent and conventional effluent (from a 60% C102 bleaching sequence) resulted in immediate changes in treatment efficiency. Switching from TCF to conventional effluent decreased BOD removal, whereas switching from ECF to conventional effluent increased BOD removal. The addition of DTPA and hydrogen peroxide was found to have significant effects on activated sludge treatment. Continuous treatment of peroxide-containing wastewater reduced floe density at peroxide concentrations greater than 200 500 mg/L, although treatment efficiency was maintained. Continuous treatment of DTPA containing wastewater resulted in BOD removal efficiencies of 60% at DTPA concentrations greater than 600 mg/L. The addition of both DTPA and peroxide at typical TCF bleached kraft mill effluent (BKME) residual concentrations caused biological treatment to cease entirely. Individually, the effects of hydrogen peroxide and DTPA were: the reduction of biomass metabolic activity at concentrations of 100 mg/L H 2 Q, and 500 mg/L DTPA, the induction of catalase activity upon H 2 0 2 addition, and the release of cellular material due to cell wall damage at DTPA concentrations greater than 50 mg/L.
Annealing-Induced Effects on the Chemical Structure of the In2S3/CuIn(S,Se)2 Thin-Film Solar Cell Interface

We have investigated the impact of heat treatments on the chemical structure of the In2S3/CuIn(S,Se)2 thin-film solar cell interface using X-ray photoelectron and soft X-ray emission spectroscopy. As-grown, we find the formation of a sulfur-poor (indium-rich) In2S3 surface, an abrupt interface, and sulfur atoms in both In2S3 and CuIn(S,Se)2 chemical environments (as expected for an abrupt interface and a thin overlayer). After a heat treatment at 200 °C to simulate subsequent process steps, a strong copper and sodium diffusion into the In2S3 layer is observed. This diffusion extends throughout the layer, indicating the formation of a copper–indium–sulfide phase.
Sampling Position under No-Tillage System Affects the Results of Soil Physical Properties

Understanding the spatial behavior of soil physical properties under no-tillage system (NT) is required for the adoption and maintenance of a sustainable soil management system. The aims of this study were to quantify soil bulk density (BD), porosity in the soil macropore domain (PORp) and in the soil matrix domain (PORm), air capacity in the soil matrix (ACm), field capacity (FC), and soil water storage capacity (FC/TP) in the row (R), interrow (IR), and intermediate position between R and IR (designated IP) in the 0.0-0.10 and 0.10-0.20 m soil layers under NT; and to verify if these soil properties have systematic variation in sampling positions related to rows and interrows of corn. Soil sampling was carried out in transect perpendicular to the corn rows in which 40 sampling points were selected at each position (R, IR, IP) and in each soil layer, obtaining undisturbed samples to determine the aforementioned soil physical properties. The influence of sampling position on systematic variation of soil physical properties was evaluated by spectral analysis. In the 0.0-0.1 m layer, tilling the crop rows at the time of planting led to differences in BD, PORp, ACm, FC and FC/TP only in the R position. In the R position, the FC/TP ratio was considered close to ideal (0.66), indicating good water and air availability at this sampling position. The R position also showed BD values lower than the critical bulk density that restricts root growth, suggesting good soil physical conditions for seed germination and plant establishment. Spectral analysis indicated that there was systematic variation in soil physical properties evaluated in the 0.0-0.1 m layer, except for PORm. These results indicated that the soil physical properties evaluated in the 0.0-0.1 m layer were associated with soil position in the rows and interrows of corn. Thus, proper assessment of soil physical properties under NT must take into consideration the sampling positions and previous location of crop rows and interrows.
PREPARATIVE SEPARATION OF HYDROXYL SAFFLOWER YELLOW A AND ANHYDROSAFFLOR YELLOW B IN PLANT EXTRACT OF CARTHAMUS TINCTORIUS L. BY REVERSE-PHASE MEDIUM-PRESSURE LIQUID CHROMATOGRAPHY

Two known flavonoids—hydroxyl safflower yellow A (HSYA) and anhydrosafflor yellow B (anhydro-SYB)—were isolated and purified from plant extract of Carthamus tinctorius L. for the first time by reverse-phase medium-pressure liquid chromatography (RP-MPLC) using a mobile phase system consisting of acetonitrile and water containing 0.5% acetic acid with a Biotage® SNAP Cartridge KP- C18-HS column. A total of 2.92 g of HSYA and 1.07 g of anhydro-SYB from 9.2 g plant extract of C. tinctorius L. , each at 100% and 93% as determined by high-performance liquid chromatography (HPLC), respectively. The identification of the two purified compounds was achieved by congruent retention times, the data of the liquid chromatography-electrospray ionization mass spectrometry (LC-ESI-MSn) with those of the authentic standards and literature reports. The fragmentation pathway was proposed according the LC-ESI-MSn data.
Effect of land configurations, establishment techniques and sources of nutrients on Suru sugarcane (Saccharum officinarum) under Konkan conditions of Maharashtra

Field experiment was conducted during suru (Saccharum officinarum L.) season (January) of 201417 to inves- tigate the effect of land configurations, establishment techniques and sources of nutrients on suru sugarcane (Sac- charum officinarum L.) under Konkan condition, at Agronomy Farm, College of Agriculture, Dapoli, Maharashtra. Weather during both the years was favourable and suitable for cultivation of sugarcane. The experiment was laid out in strip-split plot design comprising of 36 treatment combinations replicated thrice. Horizontal strips consisted of three land configurations. The vertical strips consisted of four establishment techniques with three sources of nutrients. Horizontal strips consisted of land configurations, viz. ridges and furrow (C ), broad bed furrow (C ) and 1 2 flat bed (C ). Vertical strips consisted of establishment techniques, viz. Planting two bud sets in field (M ), planting 3 1 single bud settlings raised in soil + FYM in 1:1 proportion (M ), planting single bud settlings raised in soil + 2 cocopeat in 1:1 proportion (M ) and planting single bud settlings raised in soil + vermicompost in 1:1 proportion 3 (M ) while sources of nutrients, viz. application of 100% RDF through straight fertilizers (F ), application of 75% 4 1 RDF through Modified Konkan Annapurna briquettes 2:1:1 (F ) and application of 50% RDF through modified 2 Konkan Annapurna briquettes 2:1:1 (F ). From the 3 years investigation, it is concluded that for obtaining higher 3 yield and net returns from sugarcane in lateritic soils of Konkan region, it should be grown by paired row planting on ridges and furrows with drip irrigation by using single bud settling raised in soil + FYM in 1:1 proportion and should be fertilized with recommended dose of fertilizers (250:125:125 kg NPK/ha) through straight fertilizers.
