Adult Education Teachers’ Competencies for the Implementation of Sustainable Development

This paper presents the results of a study conducted on a sample of teachers working in adult education in Croatia with the aim of determining whether they possess the competencies needed for the implementation of sustainable development in the teaching process. The results show that the teachers who participated in the study mostly expressed positive attitudes but lower levels of both knowledge about sustainable development concepts and education for it. Even though teachers on average self-evaluated that they possessed almost every generic and specific competency needed for sustainable development, their self-evaluation also shows that they only partially possess the competencies directly connected with the implementation of sustainable development in the adult education teaching process.
Mixture Ratio Design Optimization of Coal Gangue-Based Geopolymer Concrete Based on Modified Gravitational Search Algorithm

A green concrete, new type of coal gangue-based geopolymer concrete, was prepared. Coal gangue geopolymer concrete contains many mineral admixtures and alkaline activators; the concrete mixture ratio design has always been a complex problem. The framework of the mix design optimization by the proposed method is established in this work. The paper aims to minimize the economic cost under the premise of ensuring the strength and workability of coal gangue-based geopolymer concrete. Gravitational search algorithm (GSA) has the advantages of faster convergence speed and stronger exploitation performance compared with the traditional optimization algorithms. However, GSA tends to premature convergence and local optimum, with weak search ability. Therefore, chaotic map is introduced in the work here. Gravitational search algorithm was modified based on Chebyshev map in chaotic theory, and the modified equations were derived. The modified algorithm was verified by the calculation of typical functions. And results from traditional GSA and GSA modified by another chaotic mapping, logistic mapping, were compared and the characteristics of different GSA were analyzed and concluded. After that, the mix design of geopolymer concrete based on coal gangue with different strength grades was optimized with the modified GSA. Through analysis of the optimization results, cost variation of different strength grade coal gangue-based geopolymer concrete was revealed. Costs declined significantly; the higher the grades within a certain strength range, the more saved. Therefore, it can be inferred that the modified gravity search method provides a reliable tool for the optimization of mixture ratio of similar geopolymer concrete.
Clinicopathological and Microscopic Features of Trypanosoma brucei and Trypanosoma evansi Induced Infections in Sheep II

The present study elucidates further on clinical, gross, and microscopic pathologies induced by single or mixed infections with Trypanosoma evansi and Trypanosoma brucei in sheep. Briefly, the experimental animals were divided into four groups of three animals each. Animals in each group were either infected with T. brucei, T. evansi, mixed (T. brucei and T. evansi), or noninfected. Animals were observed for clinical, gross, and microscopic pathologies for 98 days (14 weeks). The clinical pathologies observed included loss of body condition, pale ocular mucus membrane, rough hair coat, scrotal oedema, scrotal degeneration, emaciation, and death. At necropsy, macroscopic or gross lesions included very pale and anaemic carcass composition, congested and pneumonic lungs with severe haemorrhages, serous atrophy of intestinal and body fats, lymphadenopathy, splenomegaly, and hepatomegaly. Microscopic lesions observed in the testes, spleen, liver, lungs, lymphoid, heart, and brain tissues of infected sheep were varied and included swollen kidney with renal tubular degeneration, the proliferation of lymphocytes at the germinal centers of the spleen, degeneration of the bronchioles, severe testicular degeneration with a reduction in the number of spermatogenic cell layers, degenerated Leydig and Sertoli cells with loss of sperm reserves in the seminiferous lumen, congested liver with sinusoidal spaces and the proliferation of monocytes and lymphocytes. The results indicate that trypanosomosis due to experimental T. brucei, T. evansi, or mixed infections may be an important cause of various grades of tissue and organ pathologies in sheep in trypanosome-endemic areas.
Control of chemically-driven convective dissolution by differential diffusion effects

Chemically driven convective dissolution can occur upon reaction of a dissolving species in a host phase when the chemical reaction destabilizes an otherwise stable density stratification. An A + B → C reaction is known to trigger such convection when, upon dissolution into the host solution, A reacts with B present in the solution to produce a sufficiently denser product C. We study numerically the effect of differential diffusion on such a chemically driven convective dynamics. We show that below the reaction front either double-diffusive or diffusive-layer convection can arise, modifying the local RayleighTaylor instability. When B diffuses faster than C, the density profile contains a local maximum at the reaction front, followed by a local minimum below it. A double-diffusive instability can develop below the reaction front, accelerating the convective dynamics and thereby enhancing the dissolution rate of A into the host phase. Conversely, when B diffuses slower than C, the density profile exhibits a local maximum below the reaction front and diffusive-layer convection modes stabilize the dynamics compared to the equal diffusivity case. When B and C diffuse at equal rates but faster than A, the convective dynamics is accelerated with respect to the equal diffusivity case.
Capturing marketing practices for harnessing value-in-use

ABSTRACT This study shows that providers increasingly adapt their marketing practices to customers’ usage processes, particularly with regard to how they manage individual goal achievement, ensure continuous revenue streams, provide digitally enabled on-demand availability and guide customers’ operant resource integration. Due to its abductive research approach, this project further reveals congruences as well as ambivalences and discrepancies between theoretical suggestions in the context of service-dominant logic and value-in-use and implemented practices. In so doing, it provides a novel practice-oriented perspective on value-in-use and contributes significantly to further development of middle range theory.
An integrative analysis of genome-wide 5-hydroxymethylcytosines in circulating cell-free DNA detects noninvasive diagnostic markers for gliomas

Abstract Background Gliomas, especially the high-grade glioblastomas (GBM), are highly aggressive tumors in the central nervous system (CNS) with dismal clinical outcomes. Effective biomarkers, which are not currently available, may improve clinical outcomes through early detection. We sought to develop a noninvasive diagnostic approach for gliomas based on 5-hydroxymethylcytosines (5hmC) in circulating cell-free DNA (cfDNA). Methods We obtained genome-wide 5hmC profiles using the 5hmC-Seal technique in cfDNA samples from 111 prospectively enrolled patients with gliomas and 111 age-, gender-matched healthy individuals, which were split into a training set and a validation set. Integrated models comprised 5hmC levels summarized for gene bodies, long noncoding RNAs (lncRNAs), cis-regulatory elements, and repetitive elements were developed using the elastic net regularization under a case–control design. Results The integrated 5hmC-based models differentiated healthy individuals from gliomas (area under the curve [AUC] = 84%; 95% confidence interval [CI], 74–93%), GBM patients (AUC = 84%; 95% CI, 74–94%), WHO II-III glioma patients (AUC = 86%; 95% CI, 76–96%), regardless of IDH1 (encoding isocitrate dehydrogenase) mutation status or other glioma-related pathological features such as TERT, TP53 in the validation set. Furthermore, the 5hmC biomarkers in cfDNA showed the potential as an independent indicator from IDH1 mutation status and worked in synergy with IDH1 mutation to distinguish GBM from WHO II-III gliomas. Exploration of the 5hmC biomarkers for gliomas revealed relevance to glioma biology. Conclusions The 5hmC-Seal in cfDNA offers the promise as a noninvasive approach for effective detection of gliomas in a screening program.
Dielectric relaxation and ac conduction in multiferroic Bi0.8Gd0.1Pb0.1Fe0.9Ti0.1O3 ceramics: impedance spectroscopy analysis

ABSTRACT The solid solutions of Bi0.8Gd0. 1Pb0.1Fe0. 9Ti0.1O3 have been prepared by the solid-state reaction method. The preliminary structural studies were carried out by X-ray diffraction technique showing the formation of polycrystalline sample with ABO3 type of perovskite structure with hexagonal symmetry for the Bi0.8Gd0. 1Pb0.1Fe0. 9Ti0.1O3 ceramic system at room temperature. Dielectric properties and impedance study of this ceramic have been characterized in the temperature range room temperature to 375 °C and frequency range 100 Hz–1 MHz. The maximum ferroelectric transition temperature (Tc) of this system was in the range 200 °C–260 °C with the dielectric constant of peak to be ∼30,170 at 1 kHz. The complex impedance plot exhibited one impedance semicircle observed at low temperature, whereas two semicircles above 80 °C and the centres of the semicircles lie below the real axis, which indicates that the material is non-Debye type. Single semicircle is explained by the grain effect of the bulk and double semicircle is due to the bulk and grain boundary effect. The bulk resistance and grain boundary resistance of the materials decrease with the increasing temperature, showing negative temperature and a typical semiconducting property, i.e. negative temperature coefficient of resistance behaviour.
Pore Structure and Compressibility of Coal Matrix with Elevated Temperatures by Mercury Intrusion Porosimetry

To gain a better understanding of the effect of heat (e.g., magma intrusion, geothermal fluids and enhanced coal-bed methane recovery process) on coal reservoir properties, the pore structure and compressibility of coal matrix for low rank coal (0.69% Ro, m) with elevated temperatures were investigated by using multiple methods, including thermogravimetry-mass spectrometry (TG-MS), scanning electron microscope (SEM), N2 adsorption/desorption at 77 K and mercury intrusion porosimetry (MIP). The results from TG-MS showed that moisture and partial volatiles were removed from the coal matrix, and pore structure almost remained unchanged during the low heat treatment (25∼200°C). The micropores and transition pores consisted of more than 80% of the total pore volume based on the MIP. The pore structure was slightly changed following the temperature increase to 400°C, and the bound moisture and partial organics in the coal were released and decomposed by the increased heat, respectively. When temperature reached 400°C, organic matter decomposition of the coal released a large amount of hydrocarbon and micromolecule gases. The meso- and macropore in the coal were significantly developed, occupying ∼35% of the total pore volume. Although there was no large change in generated gas composition after 600°C, the pore volume and structures, including pore size distribution, pore volume and pore connectivity, were significantly changed based on the MIP. The pore structure acquired from MIP exhibited a deviation when the mercury intruded pressure reached 10 MPa. A fractal model was introduced to correct the MIP data and acquire the pore compressibility of the coal matrix. The results showed that the pore compressibility decreased with increasing pressure and temperature. Thus, this study provides significant implications of the pore structure evolution of underground coals that encounter heating.
Ordering kinetics of Mg-Fe2+ exchange in a Wo43En46Fs11 augite

Abstract The kinetics of Fe2+-Mg exchange between the M1 and M2 sites (FeM22+ + MgM1 = Fe2+M1 + MgM2) were followed by ordering experiments in an augitic clinopyroxene (Ca0.841Na0.019Mg0.888Fe2+0.151 Ti0.011Al0.028Cr0.003Fe3+0.054Mn0.006)(Si1.914Al0.086) from a dike on Alicudi (Aeolian Islands, Italy). The same single crystal was annealed in silica tubes in an iron-wüstite buffered Ar atmosphere, at 700, 750, 800, 850, and 950 °C, followed by quenching after each thermal treatment, and was used for the collection of X-ray diffraction data and for microprobe analysis. Kinetic constants (K) for each isotherm were calculated from the distribution coefficient KD [= (Fe2+/Mg)M1/(Fe2+/Mg)M2] measured during a series of experiments carried out by increasing annealing times until exchange equilibrium was achieved. Calculations of K were performed using the Ginzburg-Landau equation, the kinetic model of Mueller, and the mathematical formulation proposed by Sha and Chappell (1996) to check the responses of various kinetic models for a Ca-rich pyroxene on the same data set. The activation energy of the Fe2+-Mg exchange spans a narrow range, yielding values of 200 (±28) kJ/mol, independent of the method used to calculate K.
An Efficient Pairing-free Batch Verification Scheme for VANET

An intelligent traffic system, which can flexibly allocate traffic resources, serves as a good assistant to help us improve traffic safety and efficiency of controlling traffic volume, providing instant traffic information and giving priority to ambulances. Although such system is powerful, it could be misused without prop er protection. For example, malicious drivers might forge the message of the ambulance so that they can quickly pass through intersections. In addition, because traffic information is huge and needs to be processed immediately, traditional schemes that pro cess the information one by one are not competent. For this issue, a lot of batch schemes have been proposed. Most of them adopt the algorithm of Bilinear pairing while the others tries to avoid it since pairing operations are complex. However, such pairin g - free schemes are not applicable because their calculation time will explode when there are more data waiting to be processed. In this article, we briefly describe those schemes and propose a more effective one to solve the problems mentioned above.
INFORMATION SYSTEM FOR INVENTORY OF GOODS USING PROTOTYPE MODEL

Inventory management is the most important activity, because if the inventory in the warehouse is not managed properly, it will allow a decrease in profits and loss of customers. PT Andalan Teknik Karetindo Putra Bangsa has weaknesses in its inventory management activities, where the presentation of the information is done manually, namely through the process of recording in a book, then transferred to the Speedsheet application. Sometimes the data submitted is inaccurate, that is, there are still errors regarding the stock of goods. In this research, we used a prototype software model. Making this website is made to overcome these problems and to increase the effectiveness and efficiency of company performance. Where we make 2 level access rights, namely for warehouse staff and company leaders. With this website, warehouse staff can quickly and accurately find out the availability of goods and leaders can immediately find out the stock of goods available in the warehouse and can immediately print inventory reports without having to ask to the warehouse
Practical Review and Comparison of Modified Covariance Estimators for Linear Mixed Models in Small‐sample Longitudinal Studies with Missing Data

Mixed‐effects models for repeated measures (MMRMs) with an ‘unstructured’ (UN) covariance structure are frequently used in primary analyses for group comparisons of incomplete continuous longitudinal data from drug development trials. However, MMRM‐UN analysis could lead to convergence problems in numerical optimisation, especially in trials with a small sample size or high dropout rate. Although the so‐called sandwich covariance estimator is robust against the misspecification of the covariance structure, its performance deteriorates for small sample sizes. We review eight modified covariance estimators adjusted for small‐sample bias and compare their performances in the framework of MMRM analysis through simulations. In terms of the type 1 error rate and coverage probability of confidence intervals for group comparisons, Mancl and DeRouen's covariance estimator (MD) shows the best performance among the modified covariance estimators, followed by Fay and Graubard's estimator. The performance of MD is nearly equivalent to that of the Kenward–Roger method with a UN structure. The Kenward–Roger method with first‐order autoregressive structure results in substantial inflation of the type 1 error rate in the scenario where the variance of measurements increases across visits. In summary, we recommend the use of MD in MMRM analysis if the convergence problem involving a UN structure occurs in small clinical trials.
A new low power current steering logic circuit for the design of digital subsystem

ABSTRACT Managing the speed and power trade-off is becoming increasingly challenging as the power supply voltage (Vdd) is scaled down in each era. Existing logic circuits that address the trade-off require more power. A new logic circuit made up of one PMOS and two NMOS is evaluated while coupled to a typical power delivery network (PDN). Simulated in a 0.09 µm CMOS, the present circuit not only reduces the supply current but also achieves a constant delay than the CSL, MCML and CS-CMOS while the Vdd switches from 0.7 to 1.1 V. Besides, the power consumption and delay sustain a shift of 0. 14µW and 0.3ps, respectively, following a 1OC change in temperature. However, the power consumption reduces by 0. 2µW for a Vdd drop of 1mV. But the effective supply voltage close to the circuit fluctuates as the PDN draws a sudden high current. This causes the delay to change and induces jitter in the output swing. The jitter introduced for a current ramp 0–40A in 10ns is 6.7ps. The usefulness of the present design is also observed by designing a latch, master-slave flip-flop (FF), frequency divider (FD) and ring oscillator (RO). Comparing the latch, FF, FD and RO built using the conventional, proposed designs and simulated in a 0.09-µm CMOS show the lowest power and delay.
Effect of essential oils on the development of Colletotrichum sp. fungus in fragments of Feijoa sellowiana fruits

The aim of this work was to evaluate the effect of the essential oils of Syzygium aromaticum, Cymbopogon citratus, Eucalyptus citriodora and Rosmarinus officinalis on the mycelial development of the fungus Colletotrichum sp. in fragments of Feijoa sellowiana fruits. The essential oils were incorporated in the PDA (Potato-Dextrose-Agar) medium in the concentrations of 250, 500 and 1000 ppm, 0 ppm (PDA only) (negative control), and fungicide fluazinam 1% (positive control). The area under the mycelial growth curve (AUMGC) and percent inhibition of mycelial growth (PIMG) were calculated. In the second evaluation, fruits fragments bordering the disease symptom were immersed in essential oils aqueous solution of S. aromaticum, C. citratus, and E. citriodora, at the concentration of 5000 ppm, 0 ppm (water only negative control) and fluazinam 1% (positive control). The immersion times in the treatments were: 2, 4, 8, 12 and 24 hours, with subsequent incubation in Agar-Agar medium at 25°C. This evaluation was performed daily for 15 days, observing the moment of fungal germination through the emission of the mycelium. It was verified from the obtained results that all treatments reduced the fungal growth, and the essential oils of C. citratus and S. aromaticum totally inhibited its growth from the dose 500 and 1000 ppm, respectively. Regarding the test on fruit fragments, the essential oil of S. aromaticum at the immersion times of 12 and 24 hours was effective in inhibiting the fungus until the 15 day of evaluation.
Comparative Theoretical Studies on Energetic Ionic Salts Composed of Heterocycle-Functionalized Nitraminofurazanate-Based Anions and Triaminoguanidinium Cation

Density functional theory and volume-based thermodynamics calculations have been performed to study the crystal densities, heats of formation (HOFs), energetic properties, thermodynamics of formation, and impact sensitivity for the salts composed of heterocycle-functionalized nitraminofurazanate-based anions and triaminoguanidinium cation. The results show that the triaminoguanidinium nitraminofurazanate-based salts have high densities and positive HOFs. The substitution of the oxygen-containing substituent (−NO2 or −C(NO2)3) is helpful for enhancing the densities and detonation properties of the nitraminofurazanate-based salts, and the substitution of −C(NO2)3 exhibits the best performance. Incorporating the conjugated bridge −N═N– or −N═N–N═N– into the heterocycle-functionalized nitraminofurazanate-based salts is favorable for improving the density and detonation properties of its salt. The tetrazole-functionalized salts exhibit the best detonation properties among the three salt series. The calculated .
