Effects of the addition of Fe-containing slag fertilizers on the changes in Eh in Paddy soil

Abstract Flooded soil with the addition of Fe-containing slags (1% to soil) was incubated under laboratory conditions. Five commercial slags were used in this study. The slag samples were numbered from I to V in ascending order of acid-soluble Ca content. The pH of the soil solution increased with the increase in the Ca content of the slags. All the Eh (oxidation-reduction potential) in the presence of the slags were lower than that of the control during the initial 8 d period of incubation. The Eh value in the presence of slag V which contained the largest amount of Ca was the lowest throughout the incubation period. These findings suggest that the major factor of Eh decrease among others including the increase in pH, dissolution of Fe(III), and production of Fe2+ was the increase in pH. In the case of slags II, III, and IV, the pH values were below 7.0during the early stage of incubation. Although the pH values increased with the increase in the Ca content, all the Eh values in the presence of slags II,.
DEPOSIÇÃO E DECOMPOSIÇÃO DA SERAPILHEIRA EM POVOAMENTOS DE Mimosa caesalpiniifolia, Acacia mangium E Acacia holosericea COM QUATRO ANOS DE IDADE EM PLANOSSOLO

Some of the leguminous tree associated to fixing bacteria and micorrizal fungi have good development in degraded soils. Aiming to evaluate the influence of these species on soil fertility level, dry matter production and the nutrient contents of litter originated from these plants were measured during 1995. The rate of litter decomposition was evaluated by analysing the material collected in 1995 and 1996. Homogeneous stands of Caesalpiniifolia mimosa ('Sabia'), Acacia mangium and Acacia holosericea established at the experimental station of the Embrapa at 4 m2/plant spacing were used. The Embrapa Agrobiology (Seropedica (RJ) - South latitude: 33o 49' 22o 45'; Longitude West of Greenwich: 43o 38' 43o 42'; quotas varying from 18 to 33 m). The annual mean production of litterfall was 10 Mg ha-1 for Mimosa caesalpiniifolia and 9 Mg ha-1 for both Acacia species.The leaves accounted for an average 64% of the litterfall of both Mimosa caesalpiniifolia and Acacia holoricea, and 70% of Acacia mangium. Reprodutive structures were the litterfall component with the highest nutrient content. Acacia mangium showed the highest nutrient translocation among plant parts and produced the poorest litter wich presented the lowest decomposition rate. Litterfal asssociated with 'sabia' was the richest one in terms of nutrient accumulation. Different decomposition rates of litter of the tree species studied could be used as a good strategy in order to supply nutrient requirements of different crops introduced in agroforestry production systems and for the recovery of degraded lands.
QuadroNet: Multi-Task Learning for Real-Time Semantic Depth Aware Instance Segmentation

Vision for autonomous driving is a uniquely challenging problem: the number of tasks required for full scene understanding is large and diverse; the quality requirements on each task are stringent due to the safety-critical nature of the application; and the latency budget is limited, requiring real-time solutions. In this work we address these challenges with QuadroNet, a one-shot network that jointly produces four outputs: 2D detections, instance segmentation, semantic segmentation, and monocular depth estimates in real-time (>60fps) on consumer-grade GPU hardware. On a challenging real-world autonomous driving dataset, we demonstrate an increase of+2.4% mAP for detection, +3.15% mIoU for semantic segmentation, +5.05% mAP@0.5 for instance segmentation and +1.36% in δ < 1.25 for depth prediction over a baseline approach. We also compare our work against other multi-task learning approaches on Cityscapes and demonstrate state-of-the-art results.
MOBILE PAYMENT ADOPTION INTENTION DURING PANDEMIC COVID-19 IN INDONESIA

Essentially, the fast development of technology, especially the internet, has created a shift in consumer behaviour with regards to shopping that has leaned toward online shopping. This drives the sprouting of many different types of mobile payment (M-payment) that can be used as a payment tool. Moreover, the world is currently facing the COVID-19 pandemic, in addition, Indonesia is currently doing a mass scale social distancing (PSBB) to stop the infection of COVID-19, among other things limiting out of the home movement, and practicing physical distancing. This appeal makes shops advising payments using M-payment or cashless. Hence, the main purpose of this study is to identify the impact of the COVID-19 pandemic on consumer attitude in Indonesia specifically in the adoption of mobile payment (M-payment) as the safe way to do payments. The assumption of M-payment adoption is based on situational influences, personal knowledge, and perceived usefulness. The research model has been empirically tested using 217 responses from a field questionnaire conducted in a number of large cities in Indonesia – by using the multiple regression analysis techniques. The findings of the study reveal that situational influences, personal attitude, personal knowledge have a significant effect on M-payment adoption in this global pandemic of Covid-19. Meanwhile, perceived usefulness has no significant effect on M-payment adoption in this global pandemic of Covid-19. A suggestion for the M-payment providers, despite PU having no significant effect, it continues to be one of the drawing factors for people to use M-payment, hence it's best for the M-payment to continue providing benefits to its users to increase cashless payment in order to stop the spread of COVID-19. Why is it important to continue providing benefits for users? Because this study has shown that personal attitudes and personal knowledge have a significant effect on the interest of M-payment users, which means during this COVID-19 pandemic, positive attitude and people’s knowledge regarding M-payment has been shaped due to the situation, therefore, by continuously providing benefits, M-payment platforms could increase the number of people using M-payment.
The surface properties of silica gels. II. Adsorption of water vapour

Adsorption isotherms of water vapour have been determined at 25° on some laboratory and commercial samples of silica gel. A McBain-Bakr type of sorption balance, which included a ‘Pyrex’ glass spring of high sensitivity, was employed. The Brunauer, Emmett & Teller (B.E.T.) method is used to compare the water isotherms with those of nitrogen, previously determined on the same samples. It appears likely that water does not form a close-packed monolayer.
Compatible thermoplastic starch/polyethylene blends by one‐step reactive extrusion

In the presence of dicumyl peroxide (DCP), the thermal plasticization of starch and its compatibilizing modification with polyethylene was accomplished by one-step reactive extrusion in a single-screw extruder at the same time. Because of the formation of polyethylene-graft-maleic anhydride (PE-g-MAH) during the extrusion, it was used as the compatibilizer between the thermoplastic starch and polyethylene. The blending samples were characterized by means of thermogravimetric analysis (TGA), scanning electron microscopy (SEM), dynamic thermal mechanical analysis (DTMA) and Fourier-transform infrared (FTIR) analysis. The experimental results showed that in the presence of DCP the addition of MAH improved the mutual dispersion of molecules in thermoplastic starch and polyethylene. From TGA, we concluded that the thermal stability of the blends with MAH was improved compared with the blends without MAH. The DTMA and FTIR results indicated that, with the addition of MAH, the compatibility of molecules between thermoplastic starch and polyethylene in the blends was improved.

Evaluating chemical dispersant efficacy in an experimental wave tank: 2 - Significant factors determining in situ oil droplet size distribution.

Abstract Chemical dispersion is one of the most cost-effective options to remediate oil spill at open sea. Identifying significant factors that determine in situ droplet size distributions facilitates mechanistic understanding of dispersant effectiveness. In this work, in situ dispersed oil droplet size distributions were characterized during testing of chemical dispersant effectiveness of two dispersants (Corexit 9500 and SPC 1000) on two oils [Medium South American (MESA) and Alaska North Slope (ANS)] under three wave conditions (regular nonbreaking, spilling breaking, and plunging breaking waves) in an experimental wave tank. Results showed that physical dispersion generated monomodal lognormal oil droplet size distributions of larger median diameters, whereas chemical dispersion produced bi- or trimodal lognormal oil droplet size distributions of smaller median diameters over a wider range. Factorial analysis of variance (ANOVA) followed by Tukey's paired comparison statistical data analysis indicated.
Simulation of the transport of Rn222 using on‐line and off‐line global models at different horizontal resolutions: a detailed comparison with measurements,

The short-lived radionuclide Rn 222 is emitted at a fairly constant rate from the continents and is a good surrogate for studying the transport of “air pollution” from polluted continental areas to clean, remote regions. The large concentration gradients of 2–3 orders of magnitude which exist between the continents and the remote atmosphere present a major challenge to the modelling of horizontal and vertical atmospheric transport. We use the global off-line tracer transport model TM3 at 3 different resolutions. Input to the model consists of meteorological data for the year 1993 obtained from the European Centre for Medium Range Weather Forecasts (ECMWF). The same meteorological data is used to constrain the climate model ECHAM4-T42-L19. Using these meteorological data, Rn 222 simulations are used to evaluate and document model performance and associated uncertainties. High time-resolution measurements made at 2 continental stations, 2 stations under continental influence and 4 remote sites, and aircraft measurements obtained during the NARE aircraft campaign are used for a detailed comparison. Although in specific regions there are inter-model differences of up to a factor of 2 in the calculated boundary layer concentrations, these differences are not translated into a better performance of either model for the stations used for comparison. We generally obtain high correlations of model results and measurements; these range from r = 0.6–0.8 for the continental and coastal stations and 0.5–0.6 for the remote sites. Calculated mean concentrations and corresponding standard deviations generally agree favourably with observations, lending credibility to the usefulness of our models for evaluating transport of air pollutants from continental sources to remote regions. The main cause of model deviations is probably related to uncertainties in the meteorological input data set provided by the ECMWF model and to a lesser extent by our knowledge of the spatial distribution of Rn 222 emissions and uncertainties involving sub-grid scale parameterization of vertical transport, e.g., diffusion and convection.

EFFICACY OF LACTOBACILLUS ACIDOPHILUS IN REDUCING TOXICITY OF PENICILLIUM GRANULATUM IN APPLE MALUS

This study aimed to isolate and diagnose the fungi associated with imported apple fruits sold in the local markets of Najaf Governorate. results of isolating fungi showed the presence of two species of Penicillium, two of Aspergillus, in addition to the presence of Rhizopus sp. and Alternaria sp. Penicillium had the highest occurrence ranged from 95 to 100% and a frequency from 0.5 58% and 65.2% in all apple varieties (yellow, red and green), followed by Aspergillus with occurrence ranging from 33% to 45% and a frequency between 23.2% and 28.5%, while Alternaria sp. had lowest percentage of occurrence ranged from 9% to 14%, with a frequency from 2.3% to 5.2%. Penicillium isolates were also diagnosed using PCR technique, where a new isolate was detected on apple fruits in Iraq after being screened in available NCBI data and it was recorded in the name Alhlali and sequences No. MT645651. The TLC test showed that among five Penicillium isolates, one isolate P. granulatum had an ability to produce the fungal toxin, Patulin. The study showed the efficacy of Lactobacillus acidophilus in inhibiting fungal radial growth of P. granulatum by 80.87% in PDA compared to the control treatment.
Investigation of the Structures of Attached and Lifted Flames with Various Ignition Positions over a Triple Concentric Burner in the Hysteresis Regime

This study focuses on the turbulent nonpremixed flame characteristics in a triple concentric burner with the ignition positions “on the burner” (upstream position) and “above the burner” (downstream position). The flames were attached and lifted when the ignition positions were upstream and downstream, respectively. Numerical simulations were performed for cold flow, attached, and lifted flames. The calculated lift-off height and velocity profiles were in good agreement with the experimental results. In both the attached and lifted flame cases, the flame was situated along the stoichiometric mixture fraction line and in the region where the Damkohler number (Da) was >1. The stoichiometric mixture fraction curve below the lifted flame was on the same line as the stoichiometric equivalence ratio curve of the cold jet. Furthermore, it was found that the two flames exist at the crossover point of the triple curves, which are comprised of the stoichiometric mixture fraction curves of two flames, the Da = 1 cur.
Strong magnetodielectric effects in magnetorheological elastomers

The effect of a uniform magnetic field on the permittivity of magnetorheological elastomers (MREs) is studied. MREs were synthesized on the basis of silicone rubber and magnetic fillers of various chemical nature (Fe, NdFeB and Fe3O4) and particle sizes. The value of permittivity was obtained from the measurements of the capacity of a plane capacitor with MRE samples. A strong increase of the permittivity (magnetodielectric effect) was observed when the applied field was perpendicular to the capacitor plates. The value of the magnetodielectric effect was found to be strongly dependent on the type of magnetic filler as well as on the size and concentration of magnetic particles within MRE composites. The highest magnetic response reaching 150% was observed for the MRE based on a magnetically hard NdFeB filler. A simple model explaining physical reasons for the magnetodielectric effect in a MRE is proposed. The developed MRE with a strong magnetodielectric effect is very promising for a wide range of applications, in particular, as magnetic field sensors and actuators.
Amorphous germanium carbides by radiolysis-CVD of germane/ethyne systems: Preparation and reaction mechanisms

Amorphous germanium carbides have been prepared by X-ray-activated chemical vapor deposition from germane/ethyne systems. Different mixtures containing the two reagents in variable molar ratios have been investigated with the aim of determining the factors which lead to the highest yields of solid products and of obtaining information on the main ionic and radical reaction paths giving the amorphous material. To this purpose, samples were irradiated consecutively four times in 0.5-h steps. Both qualitative and quantitative GC/MS analyses of the volatile products as well as the determination of the solid composition by elemental analysis were performed after each irradiation. Moreover, the ion/molecule reactions have been studied by ion trap mass spectrometry, determining the ionic reaction mechanisms and the rate constants of the most significant processes. The results indicate that two main and opposite factors affect the formation of the amorphous product: (a) both radical and ionic paths are favored by the presence of ethyne in excess with respect to germane; (b) the increase of content of ethyne in the irradiated mixtures lowers the total number of activated species. Therefore, the best yield of amorphous germanium carbides is obtained when germane and ethyne have a molar ratio between 2/1 and 1/1.
Undulation, dilation, and folding of a layered block copolymer

The response of a mesoscopic layered structure to deformation normal to the layers is prevalently accepted to occur by an undulation instability, a model which was developed for and tested extensively in liquid-crystalline systems. This model has been applied to a layered block copolymer melt by theoretical considerations [Z.G. Wang, J. Chem. Phys. 100, 2298 (1994)] and extended to alternating glassy/rubbery layers by simulation and theory [D.J. Read et al., J. Phys. D. 32, 2087 (1999)]. In both cases, an undulation instability at extremely small strain is predicted. In this study we investigate the deformation mechanism of a lamellar block copolymer structure, stretched in the direction perpendicular to the layers, by simultaneous in situ measurements of sample stress and elongation and two dimensional small-angle x-ray scattering, at a strain resolution of 0.5%. Deformed microstructures were also observed ex-situ with scanning probe microscopy. A styrene-butadiene-styrene triblock copolymer of total mol.
Developing Language Proficiency For Academic Purposes: A Study Of Sharia Law Students In Malaysia

Understanding a second language for specific purposes is useful especially in the academic environment. In recent years, the use of Arabic for Specific Purposes (ASP) has increased particularly in Malaysia where Arabic is gaining popularity. ASP has been introduced across various fields of study including Sharia Law. Arabic language proficiency used in teaching and learning Sharia Law is required. This study aims to explore the basic proficiency required for Arabic language as a medium of studying Sharia Law among final year students of Law in Malaysia. A sample of 30 final year students of Law was selected using purposive sampling technique. This sample was chosen based on the students’ ability in academic reading and their interest in enhancing Arabic language proficiency for academic purposes. The study found that Sharia Law students consider Arabic language important in studying Sharia Law. It was also found that the students have low level of Arabic language proficiency prior to their admission into the Sharia Law program. Therefore, there is a need for special Sharia Law curriculum in Arabic. The findings of this study is expected to influence the process of Arabic curriculum development and provision of academic reading materials to further suit the needs of non-native speakers of Arabic among Sharia Law students particularly in Malaysia.
Zero-Knowledge Succinct Arguments with a Linear-Time Prover

We construct a zero knowledge argument system with polylogarithmic communication complexity where the prover runs in linear time and the verifier runs in polylogarithmic time. This achieves a central goal in the area of efficient zero knowledge. Our result is a direct consequence of a new interactive oracle proof (IOP) that simultaneously achieves linear-time proving and zero knowledge. We construct an IOP where, for the satisfiability of an N -gate arithmetic circuit over any field of size Ω(N), the prover uses O(N) field operations and the verifier uses polylog(N) field operations (with proof lengthO(N) and query complexity polylog(N)). Polylogarithmic verification is achieved in the holographic setting for every circuit (the verifier has oracle access to a linear-time-computable encoding of the circuit whose satisfiability is being proved).
The development and implementation of two industrial chemistry case studies for the Israeli high school chemistry curriculum

The development and implementation of two case studies based on local chemical industries for the Israeli high school chemistry curriculum are discussed. The same approach was used to develop both industrial chemistry case studies which may also serve as a guideline for developing case studies based on different chemical industries in other parts of the world. Key concepts of industrial chemistry, as well as their interrelationship to other disciplines are presented throughout the course of the case studies. In order to teach the industrial chemistry topics and its varied interdisciplinary components effectively, it is vital that teachers are trained to deal with all the material. Therefore, this paper also presents two different types of in‐service teacher training: a regular in‐service training course and an intensive in‐service training workshop whose goal is to train teachers to use an interdisciplinary approach effectively when teaching the industrial chemistry case studies. It is suggested that in‐s.

Characteristic magnetovolume effects in Invar type Fe-Pt alloys

The thermal expansion and the forced volume magnetostriction have been measured for the Invar type Fe-Pt alloys. Derived values of the spontaneous volume magnetostriction are large and the same order of magnitude as those for the Fe-Ni Invar alloys. Their dependence on concentration and chemical ordering can be explained by the change of Fe-Fe atom pairs and their temperature dependence satisfies the empirical relation, omega s(T)=CM2(T). The forced volume magnetostriction observed at 4.2K is about one order smaller than that for Fe-Ni Invar alloys. This suggests the presence of strong ferromagnetism in Fe-Pt Invar alloys, although this contradicts the observation of large values for the high-field susceptibility in these alloys.
The course of hydration: Its practical importance and theoretical interpretation

The practical usefulness of plaster is due to the solidification (set) which accompanies the chemical process of hydration. The paper exposes the mathematical relationship between the time it takes to hydrate (completely or to any incomplete extent) and such physicochemical parameters as the rates of dissolution and growth of the hemi- and dihydrates respectively, the solubilities, the number of dissolution and growth nuclei, particle shapes, etc. Possible modes of action of impurities, retarders and accelerators are suggested by implication. The basic principles from which this relationship is derived are mentioned. The various very different shapes which the hydration curve (extent of conversion versus time) can take are shown. A simple method is indicated to express mathematically the hydration curve of any given plaster. Reference is also being made to the relation between set and water gauge. Finally, the limitations of the theory are indicated.
