FRUIT QUALITY INSPECTION AND SELLING SYSTEM The agricultural sector is one of the most important in any country. Farmers and ranchers in some countries, however, In comparison to other developed countries, fishermen have limited technology. The low quality of crops, fruits, and vegetables is one of the consequences of limited technology. This is due to the fact that the quality of the products is only determined by external factors such as appearance, shape, colour, and texture, which are prone to human errors. When determining the quality and ripeness level of fruit, consistency is required, which can be challenging and time-consuming for individuals when it becomes repetitive work. The purpose of this paper is to present various methods and approaches for making ripe fruit detection and classification easier and more convenient by using the machine learning and machine vision algorithms.

Simulation of a Composite with a Polyhydroxybutyrate (PHB) Matrix Reinforced with Cylindrical Inclusions: Prediction of Mechanical Properties Biocomposite development, as a sustainable alternative to fossil-derived materials with diverse industrial applications, requires expediting the design process and reducing production costs. Simulation methods offer a solution to these challenges. The main aspects to consider in simulating composite materials successfully include accurately representing microstructure geometry, carefully selecting mesh elements, establishing appropriate boundary conditions representing system forces, utilizing an efficient numerical method to accelerate simulations, and incorporating statistical tools like experimental designs and re-regression models. This study proposes a comprehensive methodology encompassing these aspects. We present the simulation using a numerical homogenization technique based on FEM to analyze the mechanical behavior of a composite material of a polyhydroxybutyrate (PHB) biodegradable matrix reinforced with cylindrical inclusions of flax and kenab. Here, the representative volume element (RVE) considered the geometry, and the numerical homogenization method (NHM) calculated the macro-mechanical behavior of composites. The results were validated using the asymptotic homogenization method (AHM) and experimental data, with error estimations of 0.0019% and 7%, respectively. This model is valuable for predicting longitudinal and transverse elastic moduli, shear modulus, and Poisson's coefficient, emphasizing its significance in composite materials research.

Machine learning approach for the prediction of the number of sulphur atoms in peptides using the theoretical aggregated isotope distribution Based on the validation analysis it can be concluded that the prediction of the number of sulphur atoms based on the isotope profile fails, because the isotope ratios are not measured accurately. These results indicate that it is valuable for future instrument developments to focus more on improving spectral accuracy to measure peak intensities of higher-order isotope peaks more accurately.

Advanced Nanoscale Characterizations of Solid Oxide Cell Electrodes Solid oxide cells (SOCs) have attracted a growing attention thanks to their high efficiency and ability to operate in both electrolysis (SOEC) and fuel cell (SOFC) modes. Despite its great potential, the current SOC technology faces significant cell degradation during long-term operation. The degradation phenomena are still not well understood as they involve complex and intricate processes arising at different length scales. Additionally, it has been shown that the degradation rate under SOEC operation is generally higher than in SOFC mode. To address this issue, durability tests were performed in SOEC mode at 750, 800 and 850 °C for 2000 h at -1 A cm -2 in 10/90 vol.% H 2 /H 2 O and dry air. The electrochemical performance of the cells was assessed using electrochemical impedance spectroscopy. In addition, advanced characterization techniques with nanometer and atomic resolution have been used to study material degradation after long-term testing.

RESEARCH AND ANALYSIS OF THE TECHNOLOGY OF RESTORATION OF HYDRO-TECHNICAL STRUCTURES OF TRANSPORTATION BUILDING FROM CULVERTS BY THE SLEATHING METHOD Introduction. Hydrotechnical structures of transport construction from road culverts are used to pass water under roadways and other structures. One of the ways to increase the durability and reliability of road culverts is to carry out repairs by the sleeve method. The proposed method involves the installation of a new road culvert in the middle of a defective road culvert, and the space between the pipes is filled with mortar. The distribution of the mixture will further determine the effectiveness of the applied restoration method and the reliability of the repaired structure. The relevance of the work consists in determining the efficiency of filling the inter-pipe space with mortar. Problem Statement. From the literature analysis, it was established that road culverts are in difficult operating conditions, which is the reason for their premature destruction. The existing methods of repair do not provide the necessary quality of the restored building, and the existing global approaches are not fully studied. Purpose. It consists in refining the technology of restoration of hydraulic structures of transport construction from road culverts by the sleeve method, which ensures high reliability and durability of the structure in difficult operating conditions.

Scale Up Nanostructured Lipid Carrier (NLC) Koenzim Q10 Menggunakan Matriks Lipid Asam Stearat-Isopropil Palmitat Overexposure to the sun can lead to the production of reactive oxygen species (ROS), which accelerates the aging process of the skin. The formation of ROS can be prevented with antioxidant compounds. Coenzyme Q10 is a lipophilic antioxidant because it has 10 isoprene side chains, causing coenzyme Q10 to have low skin penetration ability. Thus, the Coenzyme Q10 Nanostructured Lipid Carrier (NLC) technology was created to improve coenzyme Q10's skin penetration. This research examined the physicochemical properties of scaled-up Coenzyme Q10 NLC formulation. The method used is High Shear Homogenization HSH), by testing two formulas, namely F1 with 20% surfactant content and 30% surfactant F2. The results obtained for the physicochemical characteristics of F1 and F2 were seen from the organoleptic parameters which were yellowish in color, semisolid, and had a characteristic odor of fat; viscosity (825.60±537.63cps; 2588.33±584.42cps), pseudoplastic flow properties; pH (5,74±0,057; 5,80±0,021), particle size (592,33±158,19nm; 257,5±39,53nm), zeta potential (-12,73±18.5mV; -36, 1±20.91mV), polydispersity index (0,461±0,129; 0,223±0,104), spherical and smooth surface morphology; decreased and increased peak height at º2Th (21.5645, 23.005; 18.9246, 22.9967), and no interaction was found between the active ingredient and the carrier. This study finds that a successful formulation of coenzyme Q10 NLC has been made.&#x0D; Scale (ratio) ; Chemistry ; Materials science ; Physics Coconut Research and Applications ; Genetics, Bioinformatics, and Biomedical Research ; Computational Drug Discovery Methods

Hybrid polypropylene biocomposites reinforced with short man-made cellulose fibres and softwood flour - optimisation of properties using Response Surface Methodology Abstract Wood-plastic composites and composites reinforced with natural and man-made cellulose fibres are being extensively used in automotive and building industries. The main shortcoming of the former is their low impact resistance and brittleness. The relatively high cost of natural and cellulose fibres is the limitation of the latter. This research uses a hybrid combination of wood flour and short man-made cellulose fibres to develop PP composites for injection moulding that excel in mechanical characteristics and have low material cost. Both reinforcements are of wood origin. The synergistic hybrid effect of this combination of reinforcements helps to achieve their mechanical performance superior to that of WPCs at preserved low cost. The proposed Response Surface Methodology enables to calculate necessary weight fractions of two reinforcements to achieve desired mechanical properties like strength, Young’s modulus and impact resistance at adopted material cost.

Stability Indicating Double Divisor Spectrophotometric Method for determination of Diloxanide Furoate and Metronidazole in Their Binary Mixture Diloxanide furoate (DXF) and Metronidazole (MTZ) are commonly combined as a binary mixture for the treatment of a variety of diseases brought on by bacteria and parasites including amoebiasis and giardiasis. Different analytical methods were established for determination of both DXF and MTZ, However, only one chemometric spectrophotometric method was established for their stability indicating determination which involves problematical steps and specific software program. Herein, double divisor ratio spectra derivative (DDRSD) method is exploited for quantification of DXF and MTZ in presence of DXF-degradation products (FUR and DEG). The recommended DDRSD method is linear over the range of 2&amp;ndash;25 and 1&amp;ndash;25 &amp;micro;g/mL for DXF and MTZ, correspondingly. Additionally, the suggested method was effectively employed to their pharmaceutical formulations with good findings. Besides, the recommended DDRSD method was validated conforming to ICH guidelines. The introduced DDRSD method is simple, selective, and economic and could be implemented for quality control samples of the studied drugs.

Statistical assessment of the comparative breaking strength of yarns with different fiber composition This article studied the factors affecting the quality of cotton yarn. The properties of cotton fiber and their changes in technological processes play an important role in product production. Therefore, cotton fibers with different staple lengths of 28.5, 29.0, and 29.5 mm were used in the test work. Because it is advisable to use long fiber cotton fiber to get single yarn spun for sewing threads, for each option, different twists on the thread, i.e. the number of twists in 1 meter of thread were 850, 900, 950 b/m. The strength of individual threads ensures the quality of the product obtained from it, so we use the above number of twists. In order to determine the relative breaking strength of a single thread for sewing threads, experimental tests were conducted. According to the conducted experimental tests, 2 incoming factors were selected. As an output parameter, the relative tensile strength of the yarn, sN/tex (U) as input parameters, the effect of fiber staple length in mm, and the number of twists on the b/m indicator were studied based on the experiment. As a result of theoretical studies, the optimal value of the relative breaking strength of the thread from 16.25 sN/tex to 17.54 sN/tex, the staple length of the fiber should be more than 29.5 mm, and the number of twists should be 900 twist/meter It was determined that it should be. Based on the obtained conclusions, scientific and research work was carried out in the control enterprise. Based on the results of this research, the preliminary results of choosing the direction of further research were obtained. For this, LOTs were organized in the enterprise in various options. LOT-1 consists of Porloq-4, LOT-2 Bukhara-102, LOT-3 Sultan varieties. Based on the research results, the coefficient of variation in the linear density of yarns with different fiber content, the coefficient of variation in the number of twists, breaking strength, the variation coefficient in breaking strength, elongation at break, the coefficient of variation in elongation at break, comparison of the coefficients of variation for breaking strength and specific breaking strength were studied. When analyzing the effect of the composition of the fiber mixture on the physical-mechanical properties of the yarns for 3 LOTs, it was seen that the quality indicators of the yarns obtained from the LOT-1 mixture are higher than the indicators of the yarns obtained from other mixtures.

Vegetative Growth Response of Entog Dwarf Coconut (Cocos Nucifera L.) to Different Planting Hole Size and Compound Inorganic Fertilizer Application Entog Dwarf coconut is a national superior variety. The purpose of this study was to determine the vegetative growth of Entog Dwarf coconut at 7-10 months of age. The research was conducted at the Palm Plant Research Institute in Manado (Upper Kima Experimental Garden and Ecophysiology Laboratory) using a factorial group randomized design with 2 factors and 3 replications. The first factor was the planting hole with a depth of 100cm and 60cm. The second factor was compound inorganic fertilizer with doses of 1.5kg, 1.0kg, 0.5kg, and control. Nutrient analysis of soil and leaves without fertilization at 7 and 10 months and after fertilization at 10 months. The results of the analysis of variance at the 5% level showed that planting holes had a significant effect, while compound inorganic fertilizers had a significant effect on vegetative characters. The tallest plants were about 51.2-63.7cm with a dose of 0.5-1.5kg while the shortest was 27.2cm, the largest stem circumference was 10.8-11.3cm with a dose of 0,5kg and 1.5kg while the smallest was 6.42cm, and the largest number of leaves was 3.67 midribs with a dose of 1.5kg while the smallest number was 2.67 midribs, where all vegetative characters were categorized as low in control plants. The interaction between the two factors had no significant effect on vegetative growth. The vegetative characters observed were positively correlated. The results of nutrient analysis of pH, moisture content, organic carbon, nitrogen, phosphorus, potassium, stomatal index, and chlorophyll showed little difference both without fertilization and after fertilization.

Extend Nearly Pseudo Quasi-2-Absorbing submodules(II) Time series analysis is the statistical approach used to analyze a series of data. Time series is the most popular statistical method for forecasting, which is widely used in several statistical and economic applications. The wavelet transform is a powerful mathematical technique that converts an analyzed signal into a time-frequency representation. The wavelet transform method provides signal information in both the time domain and frequency domain. The aims of this study are to propose a wavelet function by derivation of a quotient from two different Fibonacci coefficient polynomials, as well as a comparison between ARIMA and wavelet-ARIMA. The time series data for daily wind speed is used for this study. From the obtained results, the proposed wavelet-ARIMA is the most appropriate wavelet for wind speed. As compared to wavelets the proposed wavelet is the most appropriate wavelet for wind speed forecasting, it gives us less value of MAE and RMSE.

Improved detection and consistency of RNA-interacting proteomes using DIA SILAC Abstract The RNA-interacting proteome is commonly characterized by UV-crosslinking followed by RNA purification, with protein recovery quantified using SILAC labeling followed by data-dependent acquisition (DDA) of proteomic data. However, the low efficiency of UV-crosslinking, combined with limited sensitivity of the DDA approach often restricts detection to relatively abundant proteins, necessitating multiple mass spec injections of fractionated peptides for each biological sample. Here we report an application of data-independent acquisition (DIA) with SILAC in a total RNA-associated protein purification (TRAPP) UV-crosslinking experiment. This gave 15% greater protein detection and lower inter-replicate variation relative to the same biological materials analyzed using DDA, while allowing single-shot analysis of the sample. As proof of concept, we determined the effects of arsenite treatment on the RNA-bound proteome of HEK293T cells. The DIA dataset yielded similar GO term enrichment for RNA-binding proteins involved in cellular stress responses to the DDA dataset while detecting extra proteins unseen by DDA. Overall, the DIA SILAC approach improved detection of proteins over conventional DDA SILAC for generating RNA-interactome datasets, at a lower cost due to reduced machine time.
