With the raising popularity of digital devices in the current society, the present image detection system is becoming a great threaten. Especially the appearance of the recaptured images. It can be used in traditional invalid digital image detection algorithm. There is a new algorithm in this paper is presented to detect the recaptured and real image. The algorithm obtains low-frequency images, directional filtering images and high-frequency images by multiple application frequency domain filtering. Then the proposed algorithm analyzes the directional filtering images and high-frequency images by means of LBP algorithm to extract features. At last, the recaptured images were classified by the SVM. The experimental results demonstrated the algorithm in this paper could be effectively identify in the recaptured images.

Hepatocellular carcinoma (HCC) is the most common liver neoplasm in dogs and can be treated by the Viscum album therapy in a curative or palliative way. The objective is to report a hepatocellular carcinoma case in a dog treated by homeopathic therapy, extending to Palliative Care, with a 24-month survival. A 12-year-old Schnauzer male with a history of a liver nodule was treated by intravenous and subcutaneous applications of V. album in different dynamization and combinations, chromotherapy, and oral homeopathic medicines. The tumor growth was controlled, and the health condition of the patient was stable while the medication was given as prescribed. However, as application frequency was reduced, tumor growth increased, and health deterioration was verified. Nevertheless and contrary to expectations, the patient had a 24-month survival. Therefore, these findings point to the potential of V. album on enhancing the quality of life, controlling tumor growth, and prolonging survival on patients with HCC. Patients under continuous treatment would benefit better of these properties.

Abstract The striped flea beetle (SFB, Phyllotreta striolata) is an important pest of the cruciferous crops in Asia. SFB is regarded as the most destructive pest of cruciferous crops in China due to the severe crop loss and frequent infestation incidents. As no SFB resistant cultivar is available at present, therefore, application of insecticides is the primary method of SFB control. On the contrary, the exploitation of chemical insecticides causes severe environmental issues and is not cost-effective. The use of a seed-pelletized coating of spinetoram effectively reduced SFB feedings on the flowering cabbage seedlings, whereas in combination with the insect-proof net, it controlled the SFB infestation throughout the cabbage growth period. The analysis of the pesticide residues in soil and different cabbage parts indicated the degradation dynamics of spinetoram. Furthermore, estimation of the half-life of spinetoram revealed that via seed-palletized application spinetoram half-life was found to be 2.82 days in soil, 4.21 days in the root, 5.77 days in the stem, and 3.57 days in the leaf, respectively. Both the lower pesticide residues and the half-life of spinetoram in soil and cabbage parts suggested it to be a promising environment and food-safe pesticide in controlling SFB. Moreover, the seed-pelletized coating ensured a sustainable release of spinetoram that can reduce the pesticide application frequency and be cost-effective and pocket-friendly for the farmers.

Abstract Slow growth rate of tissue-cultured banana seedling’s performance and high post-transplanting mortality rate are commonly due to low rate mineral content in the soil, climate change and soil-borne disease. This study aimed to evaluate the effects of potassium silicate (K2SiO3) on growth, physio-biochemical changes on Berangan banana seedlings grown under tropical climate conditions. The experiment was conducted under a rain shelter and all treatments were arranged in a randomized complete block (RCBD) design. The plants were soil drenched with K2SiO3 at constant 0.0901 M by 25 mL/plant after two weeks of transplanting with different frequencies application: 0-day interval (DI) served as control, 7 DI (12×), 15 DI (6×) and 30 DI (3×) throughout three months experimental period. Results showed that K2SiO3 (13% SiO2, 20% K2O) applied on healthy banana seedlings at 15 days interval significantly improved morphological growth trait (plant height, pseudo-stem diameter size, total leaf area, root length, and dry matter biomass) and physiological traits characters, but reduced proline and MDA content in plant tissues of banana. Hence, the results confirmed that each banana seedlings that received K2SiO3 at optimum frequency rate (15DI) had successfully enhanced the growth performance with better quality of Berangan banana seedlings at commercial-scale production.

More than 40 years ago G.N. Shangin-Berezovsky was the first to discover the effect of ultrahigh dilution substances on plant growth and development. Further studies in this area attracted interest of many scientists. Studies of the effect and use of ultrahigh dilution substances in agriculture is becoming increasingly popular worldwide. This study was aimed to determine efficiency of different ways of use of homeopathized (e.g. used in ultrahigh dilutions) fertilizers in plant cultivation. We studies the results of ultrahigh dilution fertilizers in different crops. These fertilizers were used in different modes: by watering, spraying, soaking, and strewing. The effect of the frequency of their application was also studied. In all cases when homeopathized remedies were prepared a lot of attention was paid to correct selection of fertilizers. Confirmed increase of plant productivity with the use of a fertilizer was the main criterion for its selection. The results were compared to the control group of plants which were grown in similar conditions in terms of growing technique, water supply and sun exposure. The studies demonstrated reliable increase of productivity of all studied plants with the use of ultrahigh dilution fertilizers in different modes of application. It was found out that the results in vegetables were similar between all breeds within the species, whereas in fruit trees (e.g. apple and pear trees) there was some variability of results depending on the way of selection. The results demonstrated that for fruit trees application of homeopathized fertilizers once a season was preferable and sufficient. For vegetables monthly application frequency should not be exceeded. Increasing frequency of application causes a decrease of productivity. For root crops single application at the time of planting was sufficient and effective. In such a way, our studies demonstrated effectiveness of the use of ultrahigh dilution fertilizers in plants. The results show that the use of homeopathized substances can be promising to increase productivity of agricultural crops.

The efficacy of 1-methylcyclopropene (1-MCP) in maintenance of apple fruit quality can differ depending on apple cultivar, ethylene content at harvest, 1-MCP concentration, the interval between harvest and 1-MCP application, and the number of applications. In this study, we investigated whether the 1-MCP concentration and its application frequency differently affected fruit quality attributes of the two new apple cultivars ‘Arisoo’ and ‘Picnic’. The fruits were treated with 1-MCP (as single or double treatments) at the rate of 0 μL L−1 (control), 0.5 μL L−1, 1 μL L−1, 0.5 + 0.5 μL L−1, and 1 + 1 μL L−1 for 18 h, and they were stored at 0 °C up to six months. Comparatively, the fruit qualities of 1-MCP treated fruits were higher than that of the control during cold storage, with a higher suppression of internal ethylene content and a slower reduction of titratable acidity in 1-MCP treatments than the controls throughout the cold storage in both cultivars, regardless of the concentration and number of applications. Reduction of fruit firmness and soluble solid contents were maintained by single application of 0.5 μL L−1 1-MCP in ‘Arisoo’ apple, while double application of 0.5 + 0.5 μL L−1 was needed in ‘Picnic’ cultivar. The effective concentration for weight-loss reduction was found to be the single application of 1 μL L−1 1-MCP in both ‘Arisoo’ and ‘Picnic’. Conclusively, 1-MCP as single treatment at the rate of 0.5 μL L−1 could be sufficient in inhibiting ethylene action and maintaining fruit quality losses during cold storage, particularly in ‘Arisoo’. However, double application of 1-MCP might be necessary for some quality attributes in ‘Picnic’ apple.

Abstract The integrated rice and cattle system (SITT) is an innovative technology package to increase agricultural production and encourage zero waste fulfillment. The technology components introduced include new HYV, fertilization, young seedlings, organic fertilizers, Jajar Legowo, IPM, bio urine, and compost. Although it has been implemented at the farmer level, there are insufficient details of its adoption performance; therefore, it is necessary to measure the adoption to evaluate the technology dissemination. This research objective was to analyze the farmers’ adoption level, adoption period, and technology application frequency. The research was conducted in Serdang Bedagai, North Sumatra, in 2018. The respondents were 40 farmers (cooperator and noncooperator), and the respondents’ selection was made purposively. The data obtained were analyzed using qualitative and quantitative descriptive approaches. The results showed that the adoption of technology by cooperator farmers was higher than noncooperator farmers, both from the perspective of each technology component and the level of adoption. The average duration of technology adoption by farmers was 44,0% require more than one planting season, 28,4% require one planting season, and 27,6% require less than one planting season. The frequency of technology application showed that farmers who apply SITT technology more than two planting seasons were 66,0%, exactly two planting seasons were 24,5%, and one planting season was 9,5%. Thus, to increase farmers’ adoption of technology, the technology should be suited to farmers’ preferences and needs, increase profits and ensure that the technology is available in the field. Moreover, providing continuous assistance during the introduction of technology.

AbstractThe European Green Deal aims to reduce the use of chemical pesticides by half by 2030. Decision support systems are tools to help farmers schedule fungicide spraying based on disease risk and can reduce fungicide application frequency and overall use. However, the potential benefit of decision support systems compared to traditional calendar-based strategies has not yet been rigorously quantified. Here we synthesise 80 experiments and show that globally decision support systems can reduce fungicide treatments by at least 50% without compromising disease control. For a given fixed number of fungicide sprays, decision support systems were as effective as calendar-based programs in reducing disease incidence. When the number of sprays was halved, the increase in disease incidence was lower for decision support system-based strategies than calendar-based strategies. Our findings suggest that decision support systems can reduce fungicide use while limiting the risk to plant health and resistance development.

Micromachining allows the production of parts and components on a micro scale with high precision and has become a key process to meet the growing demand for micro parts and micro components. To meet the quality requirements of the generated surfaces and reduce the cutting forces, strategies have been analysed, such as the use of the cutting fluid. Therefore, this research aimed to verify the effect of the frequency of the use of cutting fluid during the micro-milling of the Inconel 718 alloy. For this purpose, an ultra-refined cemented carbide micro end mill coated with (Al, Ti) N and 400 µm in diameter was used. A spindle speed of 20,000 rpm, a cutting speed of 13.8 m/min, a feed per tooth of 5 µm/tooth and an axial depth of cut of 40 µm were used as cutting parameters. Two frequencies of application of the cutting fluid were evaluated, corresponding to the flow rate of 40.7 and 270.0 ml/ h, in addition to the dry test. To measure the cutting forces, a Kistler dynamometer with operating range of -5 kN to +10 kN was used. In addition, the process simulation was performed using the AdvantEdge software by ThirdWave Systems. The results showed that the higher flow of the cutting fluid provided lower cutting forces and that, in dry machining, the cutting force increased significantly during the machining of a slot.
