Growth and yield of corn grown on two alluvial soils of Louisiana applied with different phosphorus rates

ABSTRACT The influence of soil properties on phosphorus (P) availability of Louisiana alluvial soils is not fully understood. A pot experiment was conducted in 2011 to evaluate the effect of different P fertilizer rate (0, 34, 67, 101 and 134 kg P2O5 ha−1) on corn growth and development on Perry clay and Commerce silt loam (sil) soils and relate Mehlich-3 and Bray-2 soil test P values with yield, total biomass, and P uptake of corn. The Bray-2 P values were six times higher than Mehlich-3 P values for Commerce sil while they were similar for Perry clay. Bray-2 and Mehlich-3 extractable-P of both soils increased with increasing P rate but only corn grown on Perry clay responded to P rate (P < 0.05). Implementation of appropriate testing procedure for estimating plant-available P in soil is an important component of effective P fertilization guidelines for corn.
Sensory analysis and physicochemical characteristics of carica [Vasconcellea pubescens] fruit leather with seaweed [Eucheuma cottonii] addition

Carica [Vasconcellea pubescens] is a type of papaya fruit mostly cultivated in the Dieng area, Central Java, Indonesia. Carica is smaller than regular papaya, has an orange to yellow color, the flesh is tough, has a lot of sap and the taste is a bit sour. One of the products that can be made from Carica is fruit leather. Fruit leather is the processed fruit puree in the form of a thin sheet with a thickness of 2-3 mm, resembles a skin, has a plastic texture, can be rolled, and has a distinctive fruit flavor. The seaweed [Eucheuma cottonii] which mostly contains carrageenan, is added in the process to give the elastic texture to the fruit leather. The purposes of this study are to compare the effect of seaweed concentration on Carica fruit preferred by panelists and to analyze the physicochemical characteristics of the fruit leather. The process of making Carica fruit leather is done by preparing Carica puree, adding sugar, adding seaweed, heating, molding, and drying. The statistical analysis shows no effect of seaweed concentration on the panelists’ preference test. The product has a sweet and slightly sour taste, yellowish to light brown color with the aroma of Carica. The physical analysis shows that the fruit leather has a thickness of 1.8-2.0 mm, a chewy texture, and a yield of 22.46-27.21%. Chemical analysis shows that the water content is 22.18-25.31%, the vitamin C content is 0.94-1.69 mg/100g, and dietary fiber is 5.19-10.31%.
Impact of Date Residues, Humic Acid and The Level of Irrigation in Growth and Yield of Onions (Allium cepa L.)

A field experiment was carried out in Anbar Governorate, Heet city, during December 2018 to May 2019 in sandy clay loamy soil . The experiment included three factors : Date residues were added at two levels (0 and 5%) of soil weight mixed with the soil, Humic acids was added to the soil in three levels (0, 15 and 30 kg ha−1 ),The amount of irrigation 100 % and 50% of the net irrigation depth calculated from the measurements of the American type A evaporation basin were added. Study factors were distributed according to the split -split plot design within RCBD with three replications. The results showed that the study parameters had a significant effect on the values of plant height, fresh weight of leaves, number of leaves, average bulb weight and total bulbs yield. The highest values of plant height, number of tube leaves, average weight of bulb, and total bulbs yield were 78.3 cm, 25.0, 85.0 gm and 30.82 ton ha-1 respectively when adding 5% of date residues and the humic level was 15 kg ha-1 and irrigation water 100% compared to 27.1 cm and 3.0, 26.1 gm and 2.0 ton ha-1 when date residues are not added, and a humic level of 0 kg ha-1 and the amount of irrigation water 5 0%. The bilateral and triple interaction between the three factors also show a significant effect on some plant traits.
Polyaniline/TiO2 Composite Nanotubes

Polyaniline (PANI) composite nanotubes (90−130 nm in diameter) containing titanium dioxide (TiO2) nanoparticles (about 10 nm in diameter) were synthesized through a self-assembly process in the presence of β-naphthalenesulfonic acid (β-NSA) as the dopant. It was found that the morphology, size, conductivity, and hydrophobicity of the PANI−β-NSA/TiO2 composite nanotubes were affected by the content of TiO2 nanoparticles in the nanotubes. The micelles composed of β-NSA anions and anilinium cations containing TiO2 were proposed to interpret the formation mechanism of the self-assembled composite nanotubes. The Raman spectra and X-ray diffraction characterizations show that the main chain of the composite nanotubes is identical to that of the doped PANI, and indicate that there is no chemical interaction between PANI and TiO2.
Development of A Doum Palm Shelling Machine

The traditional method used in Nigeria for removing the shell of doum palm is tedious, consumes time and also result in musculoskeletal strains and cuts. Despite an extensive search, no published literature was available on the development of a machine to shell the nuts of doum palm. To overcome this problem, a power operated doum palm de-shelling machine was designed and developed to help improve efficiency and productivity in producing vegetable ivory, doum oil and these can profoundly influence the socio-economic security of doum palm farmers. The average dimension of the doum palm nuts for the outer and inner shell layer in the three principal axes (namely, length, width, and thickness) were found to be 48.11mm, 37.69mm, 33.28mm and 32.59mm, 26.70, 23.09 respectively and its equivalent geometric mean diameter, surface area and sphericity were also found to be 39.22mm, 4832.42mm2, 81.52% and 27.18mm, 2320.86mm2, 83.39% respectively. All materials used in the fabrication of this machine are of standard specification and locally sourced. The machine is powered by a 0.70 hp electric motor and when the doum palm nuts are fed into the hopper, they pass through to the shelling unit where the shells are removed without causing damage to the nuts. The shelling units comprises of an adjuster and a shelling drum. The doum palm nuts flows to the shelling drum and they make impact with the shelling drum and the walls of the adjuster giving rise to a very great impact force that eventually shells the doum palm nuts. The shelled doum palm nut thereafter falls out through the outlet. The adjuster is used to regulate the shelling unit to the desired fit for different sizes of the doum palm nuts to be shelled. Performances test analysis conducted show that the machine shelled the fruits without nut breakage and also that the machine capacity is 2376 nuts/hr and the shelling efficiency is 73%.
Theoretical analysis and experimental validation of frequency-moldable electrostatic energy harvesters biased with a high elastic electret film

It is an effective strategy to improve the power output of energy harvesters by adjusting resonance frequency of the devices to adapt to complex frequency distribution of vibrations in environments. This paper presents mechanical analysis and experimental validation of a kind of light-weighted, flexible electrostatic vibrational energy harvesters with a customizable resonance frequency range. Such energy harvester consists of a stretchable electret beam, whose high elasticity was achieved by introducing a corrugated structure, an arc-shaped counter electrode, and a light seismic mass. The resonance behavior of the device can be simulated by the corrugated beam with flexible support at both ends. Mechanical analytical modeling allows one to predict resonance frequency of energy harvesters, making the devices potentially interesting for customizable resonance harvesting and broad bandwidth energy harvesting, and thus to satisfy actual application scenarios. The experimental results are in agreement with the theoretical prediction. For a device with an initial size of 15 × 10 × 9 mm3 and a seismic of 0.06 g, by modulating the length of the fluorinated polyethylene propylene electret beam from 15 to 35 mm, a customizable resonance frequency ranging 14–60 Hz, and the normalized output power up to several 100 μW was achieved, demonstrating great superiority.
Effect of precursor on the catalytic properties of Ni2P/SiO2 in methyl palmitate hydrodeoxygenation

The effect of phosphorus precursor on the physicochemical and catalytic properties of silica-supported nickel phosphide catalysts in the hydrodeoxygenation (HDO) of aliphatic model compound methyl palmitate (C15H31COOCH3) has been considered. Nickel acetate (Ni(OAc)2) and diammonium hydrogen phosphate ((NH4)2HPO4) (phosphate precursor) or nickel hydroxide (Ni(OH)2) and phosphorous acid (H3PO3) (phosphite precursor) have been used for the catalyst preparation by incipient wetness impregnation of SiO2 with an aqueous solution of the precursors, followed by temperature-programmed reduction in hydrogen flow. Chemical analysis (ICP-AES), H2-TPR, NH3-TPD, 31P MAS NMR, XRD, and TEM have been employed for the characterization of the catalysts. The optimal reduction parameters of the silica-supported nickel phosphide catalysts have been found for the phosphate and phosphite precursors in terms of their activity in methyl palmitate HDO. The Ni2P/SiO2 catalysts prepared by the phosphite method have shown higher catalytic activity in comparison with the Ni2P/SiO2 catalysts prepared by the phosphate method. The activity has been shown to depend on the catalyst handling after reduction: in situ reduced catalysts demonstrate higher conversion of methyl palmitate than the samples exposed to the reduction, passivation and re-reduction steps.
Reduction of annotation efforts for multiclass object detection by using a domain awareness data combination strategy

To train convolutional neural networks (CNN) it is common practise to collect a huge amount of data. This is cost intensive and often not applicable. Up to date several studies have investigated the concept of few shoot learning, e.g. 1-3 samples per class. Suboptimal is still the over fitting resulting from the gap between training data and representative test data in the application. Since this is still a field of intensive research, an alternative and common approach is transfer learning with data- and image augmented pictures. However, collecting and labelling data for fine-tuning can still take an enormous amount of time, when it comes to multiclass pictures in industrial applications like assembly kit verification. The kits often contain stock lists with a small interclass and a high intraclass-distance. A specific characteristic of stock lists is that parts are easily adaptable and exchangeable. To bring object detection closer to the industry, we successfully show a dataset driven approach that combines a single class collection of pictures, which we call single class (SC) dataset and adapt with a few samples the specific multiclass use case. In result, we use a model trained on a huge SC dataset that can easily and fast be adapted to specific industrial use cases.
The effect of enzyme concentration on physcical characteristics of pumpkin (Cucurbita moschata) puree and its dried extract

Pumpkin (Cucurbita moschata) contain many nutritional and biologically active components such as carotenoid content, polysaccharides, sterols, vitamins and protein. Since pumpkin has perishable characteristics, pumpkin must be preserved to increase the shelf life. The present study describe the possibility of producing spraydried pumpkin extract to increase the shelf life. Since pumpkin have high viscosity, it tend to cause deposit in the wall of spray drying chamber. With the help of enzyme liquefaction technique, the viscosity of the pumpkin can be reduced. In this research, pumpkin puree were individually treated with Pectinex Ultra-SP (0-2.5% w/v). Then, concentration Pectinex Ultra SP that produce the best viscosity reduction of pumpkin puree were chosen and treated with Celluclast 1.5 L (0-2.5% w/v). The results showed that 2.5% w/v of both Pectinex and Celluclast 1.5 L produced high viscosity reduction, clarity, total soluble solid and low pH. Then this pumpkin extract are subjected to spray drying condition and physical properties are measured. The spray drying of pumpkin extract with 2.5% w/v Celluclast 1.5 L and 2.5% w/v of Pectinex Ultra SP showed the higher yield of pumpkin powder, while no differences in moisture content, water activity and colour.
Users’ Intentions and Behaviors Toward Portable Scanner Application – Do Education and Employment Background Moderates the Effect of UTAUT Main Theory?

The use of the Android Operating System in almost all smartphones in the world broadens the possibility of how people use the smartphones itself, including the use of smartphone cameras as an alternative to scanners. This article discusses how people behave in using the scanner application on smartphones for the purpose of document scanning. The method used here is the Extended Unified Theory of Acceptance and Use of Technology (UTAUT) analysis or called UTAUT2 with the addition of moderating variables outside the UTAUT2 model, namely the level of education and employment of 296 respondents that explores some questions regarding their behavior in using portable scanner application on their smartphones. The results of this study show that not all factors in UTAUT affect people’s desire to use this application. Some factors which also have a partial result is the moderating effect of the factors of age, experience, level of education and employment.
Wax Deposition in the Oil/Gas Two-Phase Flow for a Horizontal Pipe

An experimental flow loop was designed and constructed to perform the wax deposition tests under the oil/gas two-phase flow conditions in a horizontal pipe. The oil sample came from the Daqing Oilfield of China, which was characterized by high wax content. A particular local sampler was designed and installed at the outlet of the test section in the flow loop to make up for the drawback of no visual observation during the course of flow pattern verification, which is a good device to help verify the flow pattern by analyzing the inner flow situations at different circumferential and vertical positions. Using the local sampler in combination with analyzing the changes in pressure drop and liquid holdup, which is defined as the fraction of an element of pipe occupied by liquid at the same instant, flow patterns were identified and divided into two main categories, namely, the stratified flow and slug flow. Wax deposition tests were selected in the definite flow pattern regions instead of flow pattern transi.
Effect of different nitrogen fertilizers on nutritional status and some fruit quality parameters of the apple cv. Starkcrimson

The effect of certain fertilizers (potassium nitrate, calcium nitrate, ammonium sulphate and urea) on the nutritional status and some fruit quality parameters of the apple cv. Starkcrimson was investigated. The highest yield was measured when plants were fertilized with the higher dose of potassium nitrate. By increasing N dose at all treatments, yield increased too. Furthermore, application of potassium nitrate increased yield compared to ammonium sulphate and urea. By increasing N dose at all treatments, mean fruit weight increased too. Application of all type of fertilizers improved fruit shape. Soluble solids content was not significantly affected by the various treatments. Flesh firmness was significantly higher when plants were fertilized with potassium nitrate compared to ammonium sulphate for the same N units applied. Higher fruit set was measured after application of potassium nitrate compared to the other treatments. From our results it is concluded that the higher yield that was measured after application of potassium nitrate compared to ammonium sulphate and urea could be ascribed to higher fruit set. At the 2 rd and the 3 rd years of the experiment, by increasing N dose of fertilizers, N concentration of leaves increased but only at the case of potassium nitrate was significantly higher. Application of ammonium sulphate increased N concentration of leaves more than urea.
CHEMICAL OXIDATION OF TREATED TEXTILE EFFLUENT BY HYDROGEN PEROXIDE AND FENTON PROCESS

In this study the possibility to apply the oxidation process for treating textile effluents, by using hydrogen peroxide and Fenton process was evaluated through determining the color and chemical oxygen demand (COD) removal. The experimental variables studied include the dosages of hydrogen peroxide and iron salts, oxidation time and pH value. The result showed that oxidation process using hydrogen peroxide alone is inefficient in COD and color removal, since only 25 % of COD removal and 21.3 % of color removal were obtained at 100 mg/L H2O2 dosage, pH 5 and 60 minutes contact time. Fenton process is normally used in textile wastewater treatment. However, in Malaysia, it is a new technology applied for treatment of textile effluents. Results obtained from this study showed that Fenton process is efficient in removing color. The color removal reaches a maximum of 90% at reaction time of 30 minutes under the action of the Fenton reagent. Although the COD removal is not very effective using Fenton process, in this study it still complies standard B in Environmental Quality Act, 1974. The percentage of COD removal obtained from this experiment is 67.1 % and the concentration is 85 mg/L under 125 mg/L H2O2 dosage, 3 mg/L Fe 2+ dosage and pH 4. From this study one may conclude that Fenton process for the treatment of textile effluent favors rather the removal of color than of COD.

Effect of conceptual change texts on physics education students’ conceptual understanding in kinematics

The purpose of this research was to determine the effect of conceptual change oriented instruction using Conceptual Change Texts (CCT) toward the physics education students’ conceptual understandings in kinematic. The research used quasi-experimental method with pre-test and post-test control group design. The sample was selected based on purposive sampling technique comprised of two groups of students from two different campuses of a public university in South Sumatra, Indonesia. The instrument used was the Indonesian version of the Force Concept Inventory (FCI). The data was analyzed to determine the mean N-gain of the experimental and control group while the independent sample U-test by α = 0,05 were used to test the hypothesis. The findings showed that 1) there were some students’ alternative conceptions with the level of their conceptual understanding 26,2%, 2) the mean N-gain of experimental and control group were 41,85% and 1,60% respectively, and 3) there was a significant difference increases in students’ conceptual understanding between who were taught using conceptual change texts and conventional one. Therefore, in terms of alternative conceptions held by students, teachers can use conceptual texts teaching materials to facilitate students’ conceptual change.
Acoustic Emission Signal Analysis on Corroded Concrete Beam

The steel corrosion of concrete structures has been one of the primary causes of structural degradation. Early identification of the steel corrosion might help minimize the location and the duration of the repair required and the cost associated with restoration work. The acoustic emission (AE) technique is more effective for assessing the corrosion of the steel reinforcement in the concrete structures. The AE technique successfully monitors and analyses energy signals released from the crack of the concrete matrix by the corrosion activity using AE sensors placed on the concrete surfaces. The main objective of this research is to assess the flexural behaviour of the corroded concrete beam specimens under the loading test using the AE technique. Three concrete beams were performed for the evaluation of corroded concrete beam specimens using the AE technique. During the experiments, the corroded beam specimens were flexural loaded together with data acquisition by the AE technique. The data obtained were processed, and AE parametric-based analysis was carried out. The AE technique was successfully conducted for fracture monitoring of the corroded beam specimen under flexure load. The AE parameters include the AE hits, and the Ib-value of the AE data was successfully introduced to assess the flexure behaviour of the corroded concrete beam specimens. It can be found that fluctuation follows a rising pattern in the Ib-value and then a declining trend in the Ib value. The lowest Ib-value exists at the damage stage IV for all beam specimens except the HC beam specimen. The lowest Ib-value occurs at the beginning of the damage stage III for the HC beam specimen.
Studying the Effect of Different Fertilizers Types and Methods of Application on Nodulation, Growth and Yield of Some Chickpea Varieties Under Rainfed Conditions

This experiment was conducted in Sharya-Duhok area, Iraqi Kurdistan region under rainfed conditions during the season of 2018-2019 to study the nodulation status, growth and yield performance of two local varieties of chickpea (Shamy and Marakshy) in relation to three different fertilizers types and methods of application i.e. bio fertilizer (Corabac G) and seed priming in super phosphate 2% and Diammonium phosphate (DAP) in addition to control treatment. The experiment was designed by Randomized complete block design with four replications. The results clearly showed significant reduction in both number and dry weight of nodules per plant in fertilizer treatment as compared to untreated (control treatment), except seed priming in super phosphate 2% as it significantly enhanced the nodule dry weight displaying non responding of chickpea to soil fertilization in regards of nodules development. However the final seedyield was not significant in the study, but its highly correlated to the above ground biomass (r =0.74**) and number of seeds per plant (r = 0.33*); Shamy variety of chickpea was superior in number of branches, number of pods and seeds per plant, while the Marakshy variety was superior in the plant height, height of lowest pod, and weight of seeds. Regarding fertilizers treatments effects, both seed priming in super phosphate and DAP fertilizer treatments were significantly surpassed in number of branches, pods and seeds per plant. Shamy variety performed better in number of branches and seeds per plant with DAP fertilizer, while Marakshy produced the same traits better in seed priming treatment. Bio-fertilizer (Corabac G) was inferior in most of the studied traits of chickpea. Accordingly, the obtained results conclude that the nodulation in chickpea not respond to the soil application of fertilizers, while positively to seed treatment (priming). The results also suggest both method of fertilization (DAP and seed priming) for improving yield related componets, but Corabac G bio fertilizer is not recommended under similar conditions.
