Data acquisition for testing potential detection of Flavescence dorée with a designed, affordable multispectral camera
Authors: Barjaktarović Marko , Santoni Massimo , Faralli Michele , Bertamini Massimo , Bruzzone Lorenzo
Published: September 2023

There is a constant push on agriculture to produce more food and other inputs for different industries. Precision agriculture is essential to meet these demands. The intake of this modern technology is rapidly increasing among large and medium-sized farms. However, small farms still struggle with their adaptation due to the expensive initial costs. A contribution in handling this challenge, this paper presents data gathering for testing an in-house made, cost-effective, multispectral camera to detect Flavescence dorée (FD). FD is a grapevine disease that, in the last few years, has become a major concern for grapevine producers across Europe. As a quarantine disease, mandatory control procedures, such as uprooting infected plants and removing all vineyard if the infection is higher than 20%, lead to an immense economic loss. Therefore, it is critical to detect each diseased plant promptly, thus reducing the expansion of Flavescence dorée. Data from two vineyards near Riva del Garda, Trentino, Italy, was acquired in 2022 using multispectral and hyperspectral cameras. The initial finding showed that there is a possibility to detect Flavescence dorée using Linear discriminant analysis (LDA) with hyperspectral data, obtaining an accuracy of 96.6 %. This result justifies future investigation on the use of multispectral images for Flavescence dorée detection.

Published: September 2023

The species diversity, abundance, and location of intestinal bacteria bear major consequences on host intestinal functions, affecting the balance between health and disease. Recent studies addressed the relative abundance of bacteria in feces and on the gut mucosal surface. However, few of these publications reported the absolute number of bacteria in different compartments of the gut, especially those associated with the intestinal epithelial surface, compared to the luminal content reflected by feces. In this study, the number of bacteria present in the lumen or associated with the mucosal surface of mice gut samples was calculated using the bacterial “internal standard method” during sequencing. Three spiking bacteria were used for mutual corroboration. The microbiota spatial distribution in the cecum, proximal and distal colon were studied in the lumen content and gut wall fixed niches. This study also provides an example to demonstrate that absolute and relative quantification may yield different conclusions. This study’s method may eliminate such misjudgments and provide insight into the distribution and quantity of gut microbiome.

The experiment was laid out in Randomized Block Design (RBD) with ten treatments viz., T1 (Control), T2 (100% RDF), T3 (70% RDF + 30% FYM), T4 (70% RDF + 30% Compost), T5 (70% RDF + 30% Poultry manure), T6 (70% RDF + 30% FYM + Mepiquat chloride @ 1250 ml/ha), T7 (70% RDF + 30% Compost + Mepiquat chloride @ 1250 ml/ha), T8 (70% RDF + 30% Poultry manure + Mepiquat chloride @ 1250 ml/ha), T9 (33.3% FYM + 33.3% Compost + 33.3% Poultry manure) and T10 (25% RDF + 25% FYM + 25% Compost + 25% Poultry manure + Mepiquat chloride @ 1250 ml/ha) with three replications. The data obtained revealed that treatment T2 (100% RDF) obtained higher number of stems/hill being statistically identical with all the treatments except T10, T9 and T1. Maximum plant height, LAI and haulm DMA were recorded in T2 which was statistically at par with T3, T4 and T5 and significantly superior to the rest of the treatments. The yield attributes and yield viz., number of tubers/plant, average tuber weight, processable tuber grade and total tuber yield was recorded significantly higher in T2 than all other treatments but remained statistically at par with T6, T7 and T8. Regarding the quality parameters, all the treatments showed non-significant variation except tuber dry matter content which was found significantly higher in T1 and lower in T2. The highest gross returns, net returns and B:C ratio were also obtained in treatment T2 followed by T8.

Three F2 populations derived from three non Bt hirsutum female lines (DHS-114, DHS-121, DHS-108) and male Bt parent UASD Event No. 78, independently, were evaluated for yield and yield related traits. F2 generation of three crosses recorded transgressive segregants for number of bolls per plant (45), number of monopodia per plant (38), average boll weight (36) and seed cotton yield per plant (18). Cross DHS–114 × Event No.78 recorded 15 transgressive segregants, with 0.7% to 104.6% higher seed cotton yield than check ARBH-813 (56.2 g/plant). In crosses DHS–121 × Event No.78 and DHS–108 × Event No.78, 15 and five segregants showed higher performance with yield advantage of 0.4 to 71.7% and 14.4 to 56.6%, respectively. These selected transgressive segregant plants can be advanced to further generations to help in isolating and stabilizing superior genotypes with Cry1Ac gene.

A field study was conducted in the Village Sabli of district Tehri Garhwal to know the effect of optimum levels of fertilizer on growth, yield and quality of Chilli (Capsicum annuum L.) cv Pant C 1. To assess the effect of fertilizers on yield and yield parameters randomize block design (RBD) in field and completely randomized design (CRBD) in laboratory were used with 20 treatment combinations. In this study two levels of nitrogen (40 and 80 kg N ha-1), one level of phosphorus (35 kg P2O5 ha-1), two levels of potassium (35 and 60 kg K2O ha-1) and two levels of farmyard manure (20 and 25 tonns ha-1) were taken. Among all treatment combinations, fertilizer dose of NPK and farmyard manure 80:35:35 kg and 25 t ha-1 (T9 treatment) was found most suitable for cultivation of chilli. A significant increase in yield and yield parameters were recorded like number of fruits plant-1, length of the fruit, 100 fruit weight, fruit yield kg plot-1, fruit yield q ha-1 and dry fruit yield q ha-1. The result found promising when 80 kg nitrogen, 35 kg phosphorus, 35 kg potassium and 25 tonns farmyard manure ha-1 respectively were used and was found significantly superior over other treatments. A significant effect of treatment on mean daily germination, highest value of relative growth index was recorded for T9 treatment. The T7 treatment had registered maximum mean germination time. The various treatments had significant effect on T50 and highest T50 value was observed in T7 treatment. On the basis of above study it can be suggested that fertilizer ratio of N:P:K (80:35:35) with 25 t ha-1 of FYM give good yield and plant growth.

Nanomaterials have many beneficial applications; however, their impacts on the environment necessitate an assessment. Understanding any possible negative effects of nano-based products on soil health needs to be performed before their extensive use in crop production and commercialization. Microorganisms are considered the most sensitive indicators of environmental stresses. Thus, this study assessed the effects of nanoformulated plant growth regulator (HormoGroe®) on the culturable soil bacterial population, dehydrogenase (DHA) and urease (UA) activities, and microbial biomass (MCB) in Lipa clay loam (LCL) and Sariaya sandy loam (SSL) over 75-day incubation period in the laboratory. Results showed the treatments had no significant effect on the culturable bacterial population. HormoGroe® had no adverse impact on DHA in both LCL and SSL. HormoGroe® significantly enhanced UA in SSL at 35 days after amendment (DAA) but significantly decreased UA in LCL at 75 DAA, while it decreased significantly the MCB at 35 and 1 DAA in LCL and SSL, respectively. Regardless of the amendments, LCL had higher DHA and UA but lower MCB than SSL. The effect of HormoGroe® and the non-nanomaterials on the parameters measured was influenced by soil type. In conclusion, HormoGroe® is safe for soil microbiome, mainly bacteria in crop production.

Published: September 2023

This experimental study determined the effectiveness of the Kantutay (Lantana camara Linn.) as an organic pesticide against rice stem borer (Sciropophaga incertulas). A single factor randomized complete block design was utilized for efficacy tests of the L. camara extract under laboratory and field conditions. Results showed that the extracted L. camara had an insecticidal activity against the rice stem borer. The pure concentration obtained the highest mortality rate – 86.11 and 85.19% under field and laboratory conditions, respectively. Under field conditions, the plant’s extract was significantly less effective compared to the commercial pesticide. However, it was not significantly different in terms of effectiveness under laboratory conditions.

Ultisols are old soils, inferior and acidic. However, tropical secondary forests (SF) under this soil are transformed into grasslands (GL) and forest plantations (FP) which could profoundly affect the carbon and nutrient stocks. To support efforts in conserving tropical forest, estimates of these are essential, especially in addressing climate change and carbon sequestering. This study aimed to quantify soil organic carbon (SOC), total aboveground biomass (TAGB) and nutrient stocks of SF transformations using three adjacent land-use types, namely SF, GL and FP with comparable climate, parent material, soil type and geology. Results showed that land-use mean of organic carbon, TAGB, potential cation exchange capacity, effective cation exchange capacity, exchangeable acidity, hydrogen ion, aluminum, magnesium, calcium, potassium, sodium and the base saturation decreased when SF was converted into GL and then into FP. Additionally, there was a slight increase in SOC stocks, total nitrogen, available phosphorus and pH in H2O when SF was converted into GL and then into FP. This study indicates that SF conversion into GL and FL did not affect SOC stocks and has no significant relationship with TAGB.

This study determined the heavy metal concentration of soil of Bagong Silang dumpsite and screened the phytoremediation potential of naturally occurring plants in the area. The concentrations of the heavy metals on soil and plant samples were determined using inductively coupled plasma mass spectrometry. Soil analysis showed that lead (Pb) and chromium (Cr) exceeded the permissible level accepted by the United States Environmental Protection Agency (USEPA) regulatory standards for heavy metals in residential and industrial soil. Ipomoea aquatica, Chloris barbata and Cynodon dactylon were the most dominant plant species present in the dumpsite area. In terms of heavy metal uptake in shoots, C. dactylon was the most efficient in accumulating Pb and Cr, while C. barbata and I. aquatica for arsenic (As) and cadmium (Cd) accumulations, respectively. In terms of heavy metal uptake in roots, I. aquatica was the best in accumulating almost all the heavy metals tested except Pb. Meanwhile, I. aquatica has the capacity of As and Cd phytostabilization (BCF >1) and C. barbata of Cd phytostabilization. In this study, only I. aquatica showed an enrichment factor of greater than 1 (Cd = 1. 17). The findings of the present study showed that the Bagong Silang dumpsite is contaminated with Pb and Cr. The study also revealed that C. dactylon was an efficient translocator of heavy metals in the shoots, while I. aquatica and C. barbata were most efficient in stabilizing heavy metals in the roots. However, supplementary analysis must be done to substantiate the potential of I. aquatica, C. barbata and C. dactylon as phytoremediators of heavy metals.

In the United States, attempts have already been made to use distilled spirits as an organic modifier. However, the chromatograms produced were inferior in terms of number of theoretical plates (NTP) and noise compared with chromatograms produced using HPLC grade ethanol. This study aimed at finding a locally available vodka that produces chromatograms comparable with ACS HPLC grade ethanol in terms of NTP and noise. Three brands of locally produced vodka (Cossack, Antonov and Tosca) were tested and the brand that passed the ACS set limits for absorbance and residue on evaporation was selected. The brand that passed specifications was then used for isocratic and gradient HPLC separation. All experimental runs were carried out in triplicates. It was found out that Antonov Vodka passed the said set limits, which was then used in separating caffeine and benzoic acid under isocratic and gradient modes. Results revealed that the resulting chromatograms had NTP and baseline noise that were comparable to the ACS HPLC grade ethanol. In the case of caffeine, the NTP under isocratic conditions were 6006.67±36.35 and 5943.33±12.74 for ACS HPLC grade ethanol and Antonov Vodka, respectively. Using Antonov Vodka, good separation of caffeine and benzoic acid from other matrix components in three brands of energy drinks (Cobra, Lipovitan and Red Bull) was likewise observed. Hence, with the proper validation procedures in place like testing the robustness of the analytical method, Antonov Vodka may replace HPLC grade ethanol in the analysis of some samples.

This paper presents a comparative analysis of techno-economic viability of four different system configurations (photovoltaic [PV]/diesel generator [DG], PV/battery [BAT], DG/BAT and DG-only) for energizing outdoor telecommunication sites located within the latitude 7.15˚N and longitude 3.35˚E of Abeokuta, Ogun State, Nigeria. The site used in this study has a maximum and average load of 1697 W and 39.6 kWh/day, respectively. Among all configurations examined, PV/BAT system configuration achieved the lowest life cycle cost (LCC) of ₦133,064,109 and cost of energy (COE) of ₦0.70 with a renewable fraction of 100%, adjured as the most cost-benefit configuration. However, the configuration with the least initial capital cost of ₦4,375,000 (DG-only) was the worst system configuration due to its high LCC (₦593,667,359) and COE (₦12.95). Suffice it to know that both high fuel consumption and exorbitant cost of maintenance account for this unfavorable scenario of DG-only system configuration. In line with the results obtained, it is unarguable that the system configuration with least initial capital cost might not be necessarily be the most suitable system configuration for any proposed telecommunication site. Conclusively, hybrid renewable system configuration showed superior performance relative to the long-used orthodox DG-only system.
Acoustic Characterization of Retrofit Vertical Duct Soundproof Enclosure for Portable Mini-Generators
Authors:   Mechanical Engineering Department, University of Nigeria, Nsukka Enugu, Nigeria, Agbo Cornelius O. A.
Published: September 2023

Environmental noise pollution from electric power generators has become seemingly intractable in most developing countries due to the epileptic power supply. Families as well as corporate organizations now rely on these standby generators for their daily electricity needs. The concern of this paper was the characterization of the developed vertical duct soundproof acoustic enclosure on mitigating the noise produced by portable mini generators. A total of six acoustic parallelepiped boxes were produced using chopped strand E-glass fiber mat reinforced composite panels with polyurethane foam inner lining. The generator noise spectra with and without the enclosure were obtained for comparative analysis. The sound pressure level of the generator noise at each enclosure height was also measured. It was found out that the noise level reduced by 12.8 dBA when the sound pressure levels at both conditions were taken and compared at optimal enclosure height (1600 mm). The result from exhaust ducting showed that exhaust duct projection, channeling out the fumes, did not significantly impact the enclosure insertion loss. The enclosure and the generator were also found to be in stable, acceptable thermal conditions while operating at rated load with a maximum temperature of 39 °C measured inside the enclosure. This eliminates the need for artificial cooling and its consequent power drain.

Education 4.0 in the Philippines encourages the use of advanced technologies in facilitating the educational ecosystem where teachers are required to be competent in information and communications technology (ICT). On the contrary, the established instrument in assessing the pedagogical ICT competence in the Philippines is still a manual process showing a gap between the actual and the ideal in terms of education 4.0 requirement. In this paper, it is empirical to develop a model and implement this model in actual system development where the software learns through time based on the data collected from the system users in predicting the pedagogical ICT competence of the teachers. This study was conducted in a Philippine state university, where the total enumeration of the respondents was taken. The use of Knowledge Discovery in Databases was utilized to develop a model using J48 algorithm, evaluated through 10- cross-fold validation, and used to develop an application that predicts the pedagogical ICT competence of the teacher using R programming. The result showed a significant improvement and efficiency in predicting the pedagogical ICT competence of the teachers.

The biogas-driven pump-based integrated farm with a total land area of 1.08 ha is located in Bakir, Bagabag, Nueva Vizcaya, Philippines. The farm owner was primarily practicing monoculture with rice as the product. Originally, the annual income of the farmer is Php 66,087.51. With the introduction of the biogas-driven pump-based integrated farming system (IFS), the income of the farm owner has increased to Php 196,940.13. The farm is now engaged in rice, vegetables, swine, and fish production. It was found out that both systems have a positive net present value; therefore, they are financially viable. However, biogas-driven pump-based IFS has a higher net present value of Php 601,461.41 compared with monoculture (Php 116,040.11). For the internal rate of return, biogas-driven pump-based IFS has a higher rate than the monoculture. Concerning the return on investment, the biogas-driven pump-based IFS has a rate of 25%, which is higher than the monoculture (13%).

Nowadays, smart cities are using advanced technologies to control and coordinate physical, social, and commercial enterprise systems to deliver high-quality services to their residents while guaranteeing the effective usage of available resources. Numerous major corporations, as well as government bodies, are involved in the construction of smart cities because smart city activities also need information that is obtained from organizations. Blockchain-based technology allows for peer-to-peer exchanges as a public ledger that maintains records of transactions, smart contracts, agreements, and shipments without third-party mediators. In the future, smart cities will be equipped with several innovative technologies, a huge amount of data, a lot of Internet of Things (IoT) devices, and a heterogeneous environment. However, data processing among IoT devices in futuristic smart cities is a challenging task. In this paper, the author proposed a blockchain-based big data integrity service framework for IoT devices data processing in smart cities. The author collected the necessary data from various resources and applied three experiments to evaluate the key performance indicators. K-mean algorithm was used to classify the data, and blockchain strategy was applied to ensure secure communication among IoT devices. The framework was simulated and tested using 100 devices. The proposed framework allowed IoT devices to efficiently use information collected from different resources to engage in operational processes and exchange information.

Electrical discharge machining (EDM) is one of the most crucial non-traditional machining methods used in molds and dies manufacturing, and conductive materials machining, which are difficult to machine by traditional methods. The EDM performance is affected by several machining parameters with different contribution percentages. In this study, the experimental investigations were conducted on DIN 2767 tool steel using CuCrZr, Cu and CuCo1Ni1Be (CNB) electrodes. The most influential process parameters were focused on to improve the EDM performance. The value of the process parameters and their levels were discharge current (6, 12 and 25 A), pulse-on time (50, 200 and 800 μs) and pulse-off time (50, 200 and 800 μs). Optimal levels of machining process parameters were obtained by employing the Taguchi L27 orthogonal arrays. The experimental results showed that the optimal combination of the machining parameters for maximum material removal rate was A3B2C1 using a CNB electrode. For minimum tool wear rate, the optimal parametric combination was A1B3C1 and Cu electrode. The optimal parametric combination was A1B3C3 and CuCrZr electrode for minimum surface roughness. The study further revealed the relation and interaction effect between process parameters for the performance measures. Lastly, the process parameters affected and changed the DIN 2767 tool steel workpieces’ surface integrity as evidenced by the scanning electron microscopy images.

Generating accurate and timely internal and external audit reports may seem difficult for some auditors due to limited time or expertise in matching the correct clauses of the standard with the textual statement of findings. To overcome this gap, this paper presents the design of text classification models using support vector machine (SVM) and long short-term memory (LSTM) neural network in order to automatically classify audit findings and standard requirements according to text patterns. Specifically, the study explored the optimization of datasets, holdout percentage and vocabulary of learned words called NumWords, then analyzed their capability to predict training accuracy and timeliness performance of the proposed text classification models. The study found that SVM (96.74%) and LSTM (97.54%) were at par with each other in terms of the best training accuracy, although SVM (67.96±17.93 seconds [s]) was found to be significantly faster than LSTM (136.67±96.42 s) in any dataset size. The study proposed optimization formulas that highlight dataset and holdout as predictors of accuracy, while dataset and NumWords as predictors of timeliness. In terms of actual implementation, both classification models were able to accurately classify 20 out of 20 sample audit findings at 1 and 3 s, respectively. Hence, the extent of choosing between the two algorithms depend on the datasets size, learned words, holdout percentage, and workstation speed. This paper is part of a series, which explores the use of Artificial Intelligence (AI) techniques in optimizing the performance of QMS in the context of a state university.

This study fabricated a wall-panel board made of rice husk and red clay-based geopolymer. The geopolymer paste was studied at varying molarities of alkali-activator solution with a fixed ratio of Na2SiO3/NaOH at 2.5. A calcined red clay was used as the aluminosilicate precursor at a mass ratio of 1:1 to the activator solution. The geopolymer paste was heated at 80 °C for 12 h in a conventional oven and then aged for seven days at room condition. It was found out that 12 molars of NaOH in geopolymer paste provided the maximum flexural strength of 5.48 MPa. The rice husk was then introduced to the geopolymer paste at varying amounts from 10 to 20 wt% based on the mass of the paste. It was observed that the flexural strength and bulk density of the solidified composites decreased with an increasing amount of rice husks. Correspondingly, the measured flexural strengths varied from 4.21 to 3.13 MPa, whereas the bulk densities measured from 1.84 to 1.51 g/cm3. It was further observed that the addition of rice husks at 15 wt% in the geopolymer composite exhibited a lower thermal conductivity of 0.297 W/m-°K. The increased addition of rice husks above such amount negligibly decreased the thermal conductivity of the geopolymer composite. Lastly, the fabricated wall-panel board using the rice husk and red clay-based geopolymer is a promising lightweight and insulating material in the construction industry.
